In orthopedic surgical procedures various tools and instruments are used to remove damaged or diseased bone, prepare the bone for the insertion of prosthetic implant components, to remove instruments that have been temporarily affixed to the bone or to remove previously placed or temporary prosthetic implant components. Certain tools used during these procedures provide a force toward or force away from the surgical area to assist in the surgical procedure. For example, “slap hammers” (also known as “slaphammers” or “slide hammers”) have been developed and are widely used in orthopedic procedures to apply an impacting force on various tools used during surgery. Slap hammers typically consist of a guide rod and a sliding weight. One end of the guide rod is affixed to an object, such as a device or a surgical instrument. The sliding weight may be thrown upward, away from the surgical site, generating a force when the sliding weight strikes a stop on the end of the guide rod. The sliding weight may be repeatedly “thrown” away from the surgical site to extract the device or the instrument attached to the guide rod. Alternatively, the hammer may be dropped or “thrown” downward, toward the surgical site to impact a stop at end of the guide rod that is attached to the device or instrument.
A slap hammer tool for an orthopedic procedure includes U.S. Pat. No. 6,814,738, which discloses a handle portion and a substantially cylindrical, hollow slideable mass disposed around the handle portion and mated to a surgical tool such that when the mass is positioned in a first orientation it may be used to generate a force, and when the mass is positioned in a second orientation the mass may be removed from the slap hammer tool. U.S. Pat. No. 6,709,439 discloses a hollow tube, a handle slideably disposed around the tube and a mass coupled to the handle and disposed within the hollow tube such that movement of the handle causes simultaneous movement of the mass to deliver a force. U.S. Pat. No. 8,486,084 discloses a guide rod defining a longitudinal axis, a striking member disposed on the guide rod and selectively positionable at various locations along the guide rod, and a sliding weight slideable along the guide rod between a first end of the guide rod and the striking member.
Current slap hammers used in orthopedic surgical procedures, for example to remove a femoral stem implant in hip replacement surgery, require a tool that produces significant momentum along an axis of the femoral stem implant to break the implant fixation to the bone. Thus, slap hammer tools used in orthopedic surgical procedures are large and heavy in order to generate sufficient momentum and force, making the devices difficult to use and requiring significant space for storage and transport. Accordingly, there remains a need for an improved slap hammer device that is compact for ease of handling and storage, yet provides enough momentum or “throw” to effectively apply an insertion force or removal force to an object, such as a surgical device or a surgical instrument.
A slap hammer tool includes a guide rod, including a first end configured for coupling to an object, and a second end coupled to a handle assembly. The handle assembly includes a first member and a second member slideably movable relative to each other. In certain embodiments, the handle assembly can also be slideably movable relative to the guide rod. In some embodiments one or both of the first member and the second member of the handle assembly can comprise a weight or be formed of a weighted or heavy material.
The handle assembly can be actuated by a user by sliding the handle assembly along an axis of the guide rod to generate momentum and to impact a surface or feature of the guide rod, or apply a force through the guide rod to a device or instrument coupled to the guide rod, such as a surgical instrument or a surgical device. In certain embodiments the handle assembly can include a drive feature to assist coupling and uncoupling of the guide rod with an object, such as a surgical instrument or a surgical device.
In certain embodiments a slap hammer tool system includes a guide rod, configured for coupling to an object, and a telescoping handle assembly couplable to the guide rod. The telescoping handle assembly includes at least two members telescopically engaged with one another such that one member is receivable or retractable within, and extendable from, the other member. The telescoping handle assembly allows the handle members to be stored, one within the other, providing a compact handle for use with the guide rod. In certain embodiments the telescoping handle assembly can include a drive feature to assist coupling and uncoupling of the guide rod with an object, such as a surgical instrument or a surgical device. One or more of the telescoping segments of the handle assembly can comprise a weight or be formed of a heavy material.
In other embodiments a slap hammer tool system includes a guide rod configured for coupling to an object and configured for telescopic engagement with a telescoping handle assembly, such that the guide rod is receivable or retractable within the handle assembly and extendable from the handle assembly. The guide rod when telescopically coupled to the telescoping handle assembly allows at least a portion of the guide rod to be stored within the handle assembly, providing a compact slap hammer tool for storage and transport.
The telescoping movement of the handle assembly in relation to the guide rod can generate an impacting force when one or more of the telescoping handle members are slideably moved in relation to each other and in relation to the guide rod. Extension of the telescoping handle members away from the guide rod extends the distance the handle assembly can be moved away from guide rod, creating greater momentum and allowing a longer “throw” or force to extract an object, such as an instrument or device coupled to the guide rod of the slap hammer.
The telescoping segments of the handle assembly can nest, one within the other, in a collapsed configuration. The telescoping handle assembly telescopically coupled to the guide rod permits at least a portion of the guide rod to nest within the handle assembly, providing a compact slap hammer tool for storage and transport.

Configurations and methods of use for a slap hammer tool are disclosed herein. In one embodiment, a slap hammer is configured for engagement and disengagement with an object, such as an instrument or device used in connection with a surgical procedure. For example, an engagement of the slap hammer tool with an object, such as a surgical instrument or a surgical device, can be used to insert, place, extract, reposition, or otherwise manipulate the object.
A connecting portion 102 of a slap hammer tool 100 can extend between a first end 108 and a second end 110 and can include a shaft or a guide rod 106 having a length extending between the first end 108 and the second end 110 of the connecting portion 102. A guide rod 106 of the connecting portion 102 can include a hollow body or a solid body.
In one ore more embodiments a connecting portion 102 can include a stop 112, 114 disposed on or coupled to the connection portion 102. In this configuration, an impacting feature 128, 136, 138 of the handle assembly 104 can be configured to contact a stop 112, 114 disposed on or coupled to the connecting portion 102. In some embodiments a stop 112 can be located at or adjacent to a first end 108 of the connecting portion 102. In some embodiments a stop 114 can be located at or adjacent to a second end 110 of the connecting portion 102.

When an impacting feature 128, 136, 138 of the handle assembly 104 contacts a stop 112, 114, 126 a force f in the direction of the slideable movement of a telescoping member 120, 130 of the handle assembly 104 can be applied to the stop 112, 114, 126, the force f being transmitted to a second end 110 of the connecting portion 102 and an object engaged with or coupled to the connecting portion 102, for example an object coupled to the connecting portion 102 through a engagement or connecting feature 116 of the slap hammer tool 100.
In some embodiments a telescoping handle assembly 104 can be actuated by slideable movement of a telescoping member 120, 130 of the handle assembly 104 in a first direction D1 along an axis α of the connecting portion 102 such that an impacting feature 128, 136, 138 disposed adjacent to an interior chamber 124, 134 of handle assembly 104 can apply a force f to a stop 112, 114, 126 disposed on or coupled to the connecting portion 102 or a first member 120. In some configurations a stop 112, 126 can be positioned within an interior chamber 124, 134 of the handle assembly 104.
In other embodiments a telescoping handle assembly 104 can be actuated by slideable movement of a slideable member 120, 130 of the handle assembly 104 in a second direction D2, opposite the first direction D1, along an axis α of the connecting portion 102, such that an impacting feature 128 disposed on an exterior surface of the handle assembly 104 can apply a force f to a stop 112, 114, disposed on or coupled to the connecting portion 102, and such that an impacting feature 136 of the second member 130 of the handle assembly 104 can apply a force f to a stop 128, disposed on or coupled to the first member 120. It will be understood that in any embodiment a handle assembly 104 and a connecting portion 102 can be configured such that slideable movement of a slideable member 120, 130 of the handle assembly 104 in relation to the connecting portion 102 can include slideable movement in one or both of the first direction D1 and the second direction D2.
In one or more embodiments a slap hammer tool 100 can include a connecting portion 102, as previously described, coupled to a handle assembly 104 that is configured for slideable movement relative to the connecting portion 102.

In some embodiments a slideable handle assembly can include a first member 120 and a second member 130 that can be configured for slideable movement relative to each other. In some embodiments a first member 120 can be configured for slideable movement relative to a connecting portion 102 independently of slideable movement of a second member 130 relative to the connecting portion 102. In other embodiments a slideable second member 130 can be configured for slideable movement relative to a connecting portion 102 independently of slideable movement of a first member 120 relative to the connecting portion 102. One or both of a slideable first member 120 and a slideable second member 130 of the handle assembly 104 can include tubular segments. In some embodiments a slideable handle assembly 104, including one or both of the slideable first member 120 and the slideable second member 130, can include a weight or be fabricated from a weight or a heavy material.

In some embodiments a handle assembly 104 can be configured to surround at least a portion of a guide rod 106 of a connecting portion 102. In some embodiments a first member 120 of a slideable handle assembly 104 can be configured to receive a first end 108 of a connecting portion 102. In some embodiments a first member 120 of a slideable handle assembly 104 can be configured to receive at least a portion of a guide rod 106 of a connecting portion 102.
In some embodiments a second member 130 of a slideable handle assembly 104 can be configured to be disposed about a first member 120 of the slideable handle assembly. In some embodiments a second member 130 of a handle assembly 104 can be configured to be disposed about a first end 121 of a first member 120 of a slideable handle assembly. In other embodiment a second member 130 of a slideable handle assembly 104 can be configured to surround at least a portion of a first member 120 of the slideable handle assembly 104. In some embodiments a second member 130 of a slideable handle assembly 104 can be configured to receive at least a portion of a first member 120 of the slideable handle assembly 104.
Therefore, as a slideable handle assembly 104 is slideably actuated by a user, such as by sliding a second member 130 of the slideable handle assembly 104 over at least a portion of a first member 120 of the slideable handle assembly 104 and by sliding, concurrently or consecutively with sliding of the second member 130, a first member 120 of the handle assembly 104 along an axis α of the connecting portion 102, the first member 120 of the handle assembly 104 can contact a stop 112, 114 disposed on or coupled to the connecting portion 102. When the first member 120 of the slideable handle assembly contacts a stop 112, 114 of the connecting portion 102, a force f in the direction of the slideable movement of the first member 120 can be applied to the stop 112, 114, the force being transmitted to a second end 110 of the connecting portion 102 and an object engaged with the connecting portion 102, for example an object coupled to the connecting portion 102 through a engagement or connecting feature 116 of the slap hammer tool 100.
In some embodiments a slideable handle assembly 104 configured to be slideably coupled to a connecting portion 102 can be actuated by slideable movement of a second member 130 of a handle assembly 104 over a at least part of a first member 120 of the handle assembly 104 to contact a stop 126, 128 disposed on or coupled to the first member 120 of the slideable handle assembly 104. When the second member 130 of the handle assembly contacts a stop 126, 128 on the first member 120 of the handle assembly 104, a force f in the direction of the slideable movement of the second member 130 can be applied to the stop 126, 128, the force being transmitted to a second end 110 of the connecting portion 102 and an object engaged with the connecting portion 102, for example an object coupled to the connecting portion 102 through an engagement or connecting feature 116 of the slap hammer tool 100.
In some embodiments a slideable handle assembly 104 can be actuated by slideable movement of a second member 130 of the handle assembly 104 in a first direction D1 over at least a portion of a first member 120 of the slideable handle assembly 104 to apply a force f in the direction D1 to a stop 126, 128 disposed on or coupled to the first member 120, and slideable movement of a first member 120 of a handle assembly 104 in the first direction D1 along an axis α of the connecting portion 102 to apply a force f in the direction D1 to a stop 112, 114 disposed on or coupled to the connecting portion 102. When the second member 130 of the slideable handle assembly contacts a stop 126, 128 on the first member 120 of the slideable handle assembly 104 and when the first member 120 of the slideable handle assembly 120 contacts a stop 112, 114 on the connecting portion 102, a force f in the direction D1 can be applied, respectively, to stops 126, 128 and stop 112, 114 the force continuing in a direction toward a second end 110 of the connecting portion 102 and toward an object engaged with the connecting portion 102, for example an object coupled to the connecting portion 102 through a connecting feature 116 of the slap hammer tool 100.
In some embodiments a handle assembly 104 can be actuated by slideable movement of a second member 130 in a second direction D2, opposite the first direction D1, over a portion a first member 120 of the slideable handle assembly 104 to apply a force f in the direction D2 to a stop 126, 128 disposed on or coupled to the first member 120, and slideable movement of the first member 120 of a handle assembly 104 in the second direction D2 along an axis α of the connecting portion 102 to apply a force f in the direction D2 to a stop 112, 114 disposed on or coupled to the connecting portion 102. When the second member 130 of the handle assembly contacts a stop 128, 128 of the first member 120 and when the first member 120 of the slideable handle assembly contacts a stop 112, 114 of the connecting portion 102, a force f in the direction D2 can be applied, respectively to stop 126, 128 and stop 112, 114 the force continuing in a direction toward a second end 110 of the connecting portion 102 and toward an object engaged with the connecting portion 102, for example an object coupled to the connecting portion 102 through a connecting feature 116 of the slap hammer tool 100. It will be understood that any embodiment of a handle assembly 104 and a connecting portion 102 as described herein can be configured such that slideable movement of the handle assembly 104 in relation to the connecting portion 102, including slideable movement of a slideable first member 120 and a slideable second member 130 in relation to a connecting portion 102, can include slideable movement in one or both of a first direction D1 and a second direction D2.
In one or more embodiments of a slap hammer tool 100 a connecting portion 102, as previously described, can be configured to be detachably coupled to a handle assembly 104 configured for slideable movement relative to a connecting portion 102. The handle assembly 104 can include a first member 120 configured to detachably couple the handle assembly 100 to the connecting portion 102, and a second member 130 configured for slideable movement relative to the first member 120 and relative to the connecting portion 102 when the handle assembly is detachably coupled to the connecting portion 102. One or both of first member 120 and a second member 130 of the handle assembly 104 can include tubular segments. In some embodiments a first member 120 of the handle assembly 104 can be configured to be slideably received at least partially within a tubular second member 130 of the handle assembly 104. In other embodiments a handle assembly 104 can include at least two tubular members 120, 130 such that a first member 120 can be configured to be slideably received within the second member 130.
As shown in
It will be appreciated that one or both of a first member 120 and a second member 130 of a slideable handle assembly 104, as described above, can include two or more slideable segments. For example first member 120 can include segments 120A, 120B that can be configured to slideably fit one within another, and second member 130 can include segments 130A, 130B that can be configured to slideably fit one within another, and in turn the first member segments 120A, 120B can be configured to slideably fit within the second member 130 or to slideably fit within a segment 130A, 130B of the second member 130.
In some embodiments a first segment 120A, 130A, respectively, of a first member 120 or a second member 130 can have a smaller diameter than a second segment 120B 130B, which may allow the first segment 120A, 130A to be slideable within the second segment 120B, 130B of, respectively, the first member 120 and the second member 130. In an example, a first segment 120A of a first member 120 can have a smaller diameter than a second segment 120B of the first member 120, and a first segment 120A of the first member 120 can be slideably received within the second segment 120B of the first member 120. A segment 120A, 120B of the first member 120 can have a smaller diameter than a second member 130 or a segment 130A, 130B of a second member 130, and a first member segment 120A, 120B can be slideably received within the second member 130 or a segment 130A, 130B of the second member 130. Similarly, a first segment 130A of a second member 130 can have a smaller diameter than a second segment 130B of the second member 130 and can be slideably received within the second segment 130B of the second member 130. In an example, a first member segment 120A, 120B having the largest diameter among all of the segments 120A, 120B of the first member 120 can be configured to be slideably received at least partially within a second member 130 or within a second member segment 130A, 130B having the smallest diameter among all segments 130A, 130B of the second member 130.
It will be appreciated that more or fewer segments 120A, 120B of a first member 120 and more or fewer segments 130A, 130B of a second member 130 of a slideable handle assembly 104 can be provided as required or desirable for a particular use. In particular, the number of slideable segments of a first member 120 and a second member 130 can be varied as required or desired to provide the desired “throw”, momentum or force to manipulate an object coupled to the slap hammer tool 100. Also, the length of any slideable segment 120A, 120B, 130A, 130B of a first member 120 and a second member 130 of a telescoping handle assembly 104 can be varied as required or desired to provide the desired “throw”, momentum or force to manipulate an object coupled to the slap hammer tool 100.
In some embodiments the handle assembly 104, including one or both of the first member 120 and the second member 130 of the slideable handle assembly 104, can include a weight or be fabricated from a weight or a heavy material. In some embodiments a first member 120 of the handle assembly can include a stop 126, 128 disposed on or coupled to the first member 120. In some embodiments a first member 120 of a slideable handle assembly 104 can include a first stop 126, disposed proximal to a second member 130 of the handle assembly 100 and a second stop 128 disposed proximal to a connecting portion 102 of the slap hammer tool 100.
Therefore, when a connecting portion 102 of a slap hammer tool 100 is detachably coupled to a first member 120 of a handle assembly 104, the handle assembly 104 can be actuated by a user, such as by slideably moving a second member 130 of the handle assembly 104 over at least a portion of the first member 120 of the handle assembly 100, the second member 130 of the handle assembly 104 can contact a stop 126, 128 disposed on or coupled to the first member 120 of the handle assembly 104. When the second member 130 of the handle assembly 104 contacts a stop 126, 128 disposed on the first member 120, a force f in the direction of the slideable movement of the second member 130 can be applied to the stop 126, 128, the force being transmitted to a first end 108 of the connecting portion 102, to a second end 110 of connecting portion 102, and to an object engaged with or coupled to the second end 110 of connecting portion 102, for example an object coupled to the connecting portion 102 through an engagement or connecting feature 116 of the connecting portion 102.
In some embodiments a handle assembly 104 can be actuated by slideable movement of a second member 130 of a handle assembly 104 in a first direction D1 over a portion of a first member 120 of the handle assembly 104 to apply a force f to a stop 126, 128 disposed on or coupled to the first member 120. In other embodiments a handle assembly can be actuated by slideable movement of a second member 130 of a handle assembly 104 in a second direction D2, opposite the first direction D1, over a portion of a first member 120 of the handle assembly 104 to apply a force f to a stop 126, 128 disposed on or coupled to the first member 120 or to apply a force f to a stop 112, 114 on the connecting portion 102. It will be understood that any embodiment of a handle assembly 104 and a connecting portion 102 can be configured such that slideable movement of the handle assembly 104 in relation to the connecting portion 102, including slideable movement of a second member 130 in relation to one or both of a first member 120 of the handle assembly 104 and a connecting portion 102, can include slideable movement in one or both of the first direction D1 and the second direction D2.
In one or more embodiments of a slap hammer tool 100 a connecting portion 102, as previously described, can be configured to be detachably coupled to a handle assembly 104. An example of a detachable handle assembly coupled to a connecting portion 102 is illustrated in
In other embodiments, connecting portion 102 can be detachably coupled to handle assembly 104 through a detachable coupling means 160, 162. In some embodiments, connecting portion 102 can include a coupling 160, such as a threaded portion, and handle assembly 104 can include a corresponding coupling 162 configured to mate with connecting portion coupling 160. In some embodiments connecting portion coupling 160 can include one of external threads or internal threads, and the handle assembly coupling 162 can include the other one of external threads or internal threads. It will be understood that any number of other means, fasteners and coupling mechanisms 160, 162 can be used for detachable coupling a handle assembly 104 to a connecting portion 102.
A detachable handle assembly 104 can be configured to include a slideable first member 120 and a slideable second member 130 configured for slideable movement relative to the first member 120. In some embodiments each of the first member 120 and the second member 130 can be configured for slideable movement relative to the connecting portion 102. In some embodiments slideable movement of the slideable first member 120 relative to the connecting portion 102 can be configured to be independent of slideable movement of the second member 130 relative to the connecting portion 102. In some embodiments slideable movement of the slideable second member 130 relative to the connecting portion 102 can be configured to be independent of slideable movement of the first member 120 relative to the connecting portion 102. In some embodiments, one or both of a slideable first member 120 and a slideable second member 130 of the handle assembly 104 can include tubular segments. In some embodiments a first member 120 of the handle assembly 104 can be configured to be at least partially slideably received within a tubular second member 130 of the handle assembly 104. In other embodiments, a handle assembly 104 can include at least two tubular members 120, 130, such that a tubular first member 120 can be configured to be slideably received within the tubular second member 130.
It will be appreciated that one or both of a first member 120 and a second member 130 of a slideable handle assembly 104, as described above, can include two or more slideable segments. For example first member 120 can include segments 120A, 120B that can be configured to slideably fit one within another, and second member 130 can include segments 130A, 130B that can be configured to slideably fit one within another, and in turn the first member segments 120A, 120B can be configured to slideably fit within the second member 130 or to slideably fit within a segment 130A, 130B of the second member 130.
In some embodiments a first segment 120A, 130A, respectively, of a first member 120 or a second member 130 can have a smaller diameter than a second segment 120B 130B, which may allow the first segment 120A, 130A to be slideable within the second segment 120B, 130B of, respectively, the first member 120 and the second member 130. In an example, a first segment 120A of a first member 120 can have a smaller diameter than a second segment 120B of the first member 120, and a first segment 120A of the first member 120 can be slideably received within the second segment 120B of the first member 120. A segment 120A, 120B of the first member 120 can have a smaller diameter than a second member 130 or a segment 130A, 130B of a second member 130 and a first member segment 120A, 120B can be slideably received within the second member 130 or second member segment 130A, 130B. Similarly, a first segment 130A of a second member 130 can have a smaller diameter than a second segment 130B of the second member 130 and can be slideably received within the second segment 130B of the second member 130. In an example, a first member segment 120A, 120B having the largest diameter among all of the segments 120A, 120B of the first member 120 can be configured to be slideably received at least partially within a second member 130 or within a second member segment 130A, 130B having the smallest diameter among all segments 130A, 130B of the second member 130.
It will be appreciated that more or fewer segments 120A, 120B of a first member 120 and more or fewer segments 130A, 130B of a second member 130 of a slideable handle assembly 104 can be provided as required or desirable for a particular use. In particular, the number of slideable segments of a first member 120 and a second member 130 can be varied as required or desired to provide the desired “throw”, momentum or force to manipulate an object coupled to the slap hammer tool 100. Also, the length of any slideable segment 120A, 120B, 130A, 130B of a first member 120 and a second member 130 of a telescoping handle assembly 104 can be varied as required or desired to provide the desired “throw”, momentum or force to manipulate an object coupled to the slap hammer tool 100.
In some embodiments the handle assembly 104, including one or both of the first member 120 and a second member 130 of the handle assembly 104, can include a weight or be fabricated from a weight or a heavy material. In some embodiments a first member 120 of the handle assembly can include a stop 126, 128 disposed on or coupled to the first member 120. In some embodiments a first member 120 of a slideable handle assembly 104 can include a first stop 126, disposed proximal to a second member 130 of the handle assembly 100, and a second stop 128 disposed proximal to the connecting portion 102.
Therefore, when a connecting portion 102 is detachably coupled to a slideable handle assembly 104 the slideable handle assembly 104 can be actuated by a user for slideable movement relative to the connecting portion 102, such as by sliding a first member 120 over a coupling segment of the slideable handle assembly 104 and by sliding, concurrently or consecutively with sliding of the first member 120, a second member 130 of the handle assembly 104 over at least a portion of the first member 120 of the slideable handle assembly 104, the second member 130 of the handle assembly 104 can contact a stop 126, 128 disposed on or coupled to the first member 120 of the slideable handle assembly 104. When the second member 130 of the slideable handle assembly 104 contacts a stop 126, 128, a force f in the direction of the slideable movement of the second member 130 can be applied to the stop 126, 128, the force being transmitted to a first end 108 of connecting portion 102, a second end 110 of connecting portion 102, and an object engaged with the second end 110 of connecting portion 102, for example an object coupled to the connecting portion 102 through an engagement or connecting feature 116 of the slap hammer tool 100.
In some embodiments a handle assembly 104 can be actuated by slideable movement of a first member 120 in a first direction D1 over a portion of a coupling segment of a handle assembly 104 and slideable movement of a second member 130 of a slideable handle assembly 104 in the first direction D1 over a portion of the first member 120 of the slideable handle assembly 104 to apply a force f in the direction D1 to a stop 126, 128 disposed on or coupled to the first member 120. In other embodiments a slideable handle assembly 104 can be configured to be actuated by slideable movement of a first member 120 in a second direction D2, opposite the first direction D1, over a portion of a coupling segment of the slideable handle assembly 104 and by slideable movement of a slideable second member 130 of a handle assembly 104 in the second direction D2 over a portion of the first member 120 of the slideable handle assembly 104 to apply a force f in the direction D2 to a stop 126, 128 disposed on or coupled to the first member 120 or to apply a force f in the direction D2 to a stop 112, 114 on the connecting portion 102. It will be understood that any embodiment of a handle assembly 104 and a connecting portion 102 as described herein can be configured such that slideable movement of the handle assembly 104 in relation to the connecting portion 102, including slideable movement of a first member 120 and a second member 130 in relation to a connecting portion 102, can include slideable movement in one or both of a first direction D1 and a second direction D2.
In one or more embodiments a slap hammer tool 100, as previously described, a connecting portion 102 can be configured for engagement and disengagement with an object, such as a surgical instrument or a device used in connection with a surgical procedure. An engagement feature 116 of the slap hammer tool 100 can be provided by various releasable connecting mechanisms, including, for example, a threaded connection or releasable coupling mechanism (e.g., as described in U.S. Patent App. Pub. No. 20130204265), allowing a releasable connection to be established with a slap hammer tool that is attachable to and removable from an object. Upon releasable coupling of an object to the slap hammer tool, the slap hammer tool 100 can be actuated as described above to provide force to the object in a desired direction. The releasable coupling of the slap hammer tool can be disengaged to detach the slap hammer tool from the object.
In one or more embodiments of a slap hammer tool 100 a connecting portion 102 can include an engagement feature 116 configured for engageable mating with a receiving member or receiving feature of an object, such as a surgical instrument or a surgical device. In some embodiments the removability and attachment of the engagement feature 116 from or to another object, respectively, can be provided by one or more receiving mechanisms in the object, such as threads, turn fasteners, cam fasteners, sliding fasteners, or push-button fasteners configured to receive an engagement feature 116 disposed on or coupled to a connecting end 110 of a connecting portion 102 of a slap hammer tool 100.
In some embodiments a handle assembly can include a drive feature 170 configured to engage an engagement feature 116 of the slap hammer tool 100 with a receiving feature of an object to be coupled to the slap hammer tool 100. A receiving feature of an object to be coupled to the slap hammer tool 100 can be configured (e.g., include internal threads, channels, or mechanisms) to engage an engagement feature 116 of the slap hammer tool 100 when a drive feature 170 of the slap hammer tool 100 is rotated in a first engaging direction (e.g., a clockwise direction). In a similar manner, the receiving feature of the object can be configured to disengage the engagement feature 116 of the slap hammer tool 100 when the drive feature 170 of the slap hammer tool is rotated in a second disengaging direction (e.g., a counter-clockwise direction).
Although the present slap hammer tool has been described with reference to a manipulation of an object used in connection with a surgical procedure or to perform various surgical techniques, it will be understood that the slap hammer tool as disclosed herein can be used with other objects and in connection with other manipulation procedures, methods and techniques in which a slap hammer tool can be or is customarily used.
