The present disclosure relates to an orthopedic device for compression or distraction of bone parts.
Orthopedic devices utilizing elongated pins as fasteners for compression or distraction of bone parts finds many uses for treating orthopedic patients. “Elongated pins” will be used herein to refer to various pins and wires, such as K-wires, used for fixating bone parts or providing anchors. Therefore, there is a continuing need for an improved orthopedic device that expands the scope and ability of the orthopedic surgeons in treating patients in a variety of conditions.
According to an aspect of the present disclosure an orthopedic device that can be used for compression or distraction of bone parts is described. The orthopedic device comprises an elongated body having first and second ends, a first arm member attached to and transversely extending away from said first end and terminating at an outer end and a second arm member transversely extending away from said elongated body and having a base portion and an outer end. The base portion is configured and adapted to movably engage the elongated body allowing the second arm member to be longitudinally movable along said elongated body. Said second arm member extends from the elongated body in the same direction as the first arm member. The orthopedic device also includes a locking sleeve hingeably connected to the outer end of each of the first and second arm members by a biaxial hinge block, wherein the locking sleeve is configured for receiving and locking on to an elongated pin and the biaxial hinge block is configured to allow each of the locking sleeve to swivel in two different directions with respect to its corresponding arm member about two orthogonally oriented axes.
According to another aspect, an assembly comprising a biaxial hinge block; and a locking sleeve is disclosed. In the assembly, the biaxial hinge block and the locking sleeve are configured to hingeably connect the locking sleeve to an arm member of an orthopedic device, said biaxial hinge block being configured to allow the locking sleeve to swivel in two different directions with respect to the arm member about two orthogonally oriented swivel axes.
The features shown in the above referenced drawings are illustrated schematically and are not intended to be drawn to scale nor are they intended to be shown in precise positional relationship. Like reference numbers indicate like elements.
This description of the exemplary embodiments is intended to be read in connection with the accompanying drawings, which are to be considered part of the entire written description. In the description, relative terms such as “lower,” “upper,” “horizontal,” “vertical,”, “above,” “below,” “up,” “down,” “top” and “bottom” as well as derivative thereof (e.g., “horizontally,” “downwardly,” “upwardly,” etc.) should be construed to refer to the orientation as then described or as shown in the drawing under discussion. These relative terms are for convenience of description and do not require that the apparatus be constructed or operated in a particular orientation. Terms concerning attachments, coupling and the like, such as “connected” and “interconnected,” refer to a relationship wherein structures are secured or attached to one another either directly or indirectly through intervening structures, as well as both movable or rigid attachments or relationships, unless expressly described otherwise.
The actual structural mechanism for enabling the movable engagement between the elongated body 110 and the second arm member 111 can be one of many such structures known in the art. Referring to
The base portion 113 is configured with ratcheting mechanisms that can selectably operate in compression or distraction mode. For example, the base portion 113 can be provided with a spring-loaded ratcheting pin mechanism 116 for limiting the moving direction of the second arm member 111 along the elongated body 110 to be a one-way movement, as shown in
In the configuration shown in
In order to move the elongated body 110 in the direction of the arrow BB1, the spring-loaded ratcheting pin mechanism 116 is turned 180 degrees so that the slanted side of the detent 116a is now facing in the opposite direction. This feature is used to change the direction of the one-way movement second arm member 111 so that the operation of the orthopedic device 100 is changed from compression to distraction and vice versa. The spring loaded ratcheting pin mechanism 116 can be turned 180 degrees by pulling the pin mechanism out using the thumb wheel 117, turning it 180 degrees and releasing it. The spring bias will return the pin mechanism 116 to the seated position but with the detent 116a now facing 180 degrees from before. Then, the pinion gear 115a can be turned in the direction of the arrow BB and move the elongated body 110 in the direction of the arrow BB1. Another example of the ratcheting mechanism between the base portion 113 and the elongated body 110 is described in U.S. patent application Ser. No. 13/712,300, filed by the Applicant on Dec. 12, 2012, the contents of which is incorporated herein by reference.
In the orthopedic device 100 according to the present disclosure shown I
In
Referring to
The locking sleeve 120 comprises an elongated shaft 124 having an elongated pin receiving bore 127 (see
As shown in
An example of the orthopedic device 100 with 3-point bending yoke attachments 500A and 500B attached to the first and second arm members 111, 112 is shown in
As shown in
Referring to
In the illustrated example, the first hinge joint is formed by a swivel pin 121 that is aligned with the x-axis and connects the biaxial hinge block 130 to the arm extension pieces 111a, 112a. The first swivel axis, x-axis, is oriented parallel to the elongated body 110 of the orthopedic device.
According to an aspect of the present disclosure, the first hinge joint can be configured and adapted to be normally locked at a desired swivel angle and prevented from swiveling about the first swivel axis, x-axis, by a spring-loaded locking pin 112b. When the spring-loaded locking pin 112b is pressed, the first hinge joint is unlocked and free to swivel about the x-axis.
The second hinge joint of the biaxial hinge block 130 will be described in more detail using the additional
The alignment-tab-receiving end 132 of the through-hole 131 has an opening outline that matches the transverse cross-sectional outline of the alignment tabs 128 so that in the locked first position, where the swiveling shaft 125 is pushed further into the through-hole 131, the alignment tabs 128 engage or mate with the alignment-tab-receiving end 132 and prevent the locking sleeve from swiveling about the y-axis.
In one embodiment, the locked first position holds the locking sleeve 120 in an orientation that keeps the elongated shaft 124 of the locking sleeve 120 in a parallel orientation with the arm members 111, 112 of the orthopedic device. In another embodiment, the alignment tabs 128 and the alignment-tab-receiving end 132 can be configured to hold the locking sleeve 120 in any desired angular orientation about the y-axis.
Referring to
According to an embodiment, the locking key 140 is spring-loaded within the biaxial hinge block 130 to be urged in the direction C shown in
As described, the orthopedic device 100 of the present disclosure is a universal device that can be used for compression or distraction of bone parts that are secured to the first and second arm members 112, 111 by elongated pins, such as K-wires, locked into the elongated pin receiving bores 127 of the locking sleeves 120. Referring to
Although the invention has been described in terms of exemplary embodiments, it is not limited thereto. Rather, the appended claims should be construed broadly, to include other variants and embodiments of the invention, which may be made by those skilled in the art without departing from the scope and range of equivalents of the invention. The scope of the invention disclosed herein is to be limited only by the following claims.
