This patent document pertains generally, but not by way of limitation, to an orthopedic device, tool, or instrument holder including a universal connection.
Tools or other instruments can be used by a surgeon to complete a surgical procedure (e.g., an orthopedic procedure). For example, intramedullary rods, drill guides, reamers, and pin and screw drivers can be used during the orthopedic procedure. During the procedure, when different instruments or devices are being used, the surgeon may have to switch between various device holders, which can increase surgery time.
The present inventors recognize, among other things, that a two-way quick connection and release configuration for a tool or device can be beneficial. The two-way connection allows the orthopedic device holder to be used in different configurations depending on the type of orthopedic tool being used and the preference of a surgeon. Additionally, a single activation can quickly connect and release the orthopedic tool at each configuration. The orthopedic device holder can be readily used with different orthopedic tools of differing sizes.
To further illustrate the orthopedic device holder disclosed herein, a non-limiting list of examples is provided here:
Example 1 can include subject matter such as an orthopedic device holder. The orthopedic device holder can include a body portion having a proximal end and a distal end, the body portion defining a first bore extending in a direction substantially perpendicular to a longitudinal axis of the body portion, the body portion including at least one opening extending into an interior of the first bore, a plunger portion extending into a channel of the body portion and defining a second bore, the plunger portion including at least one opening extending into an interior of the second bore, a locking bar operably coupled to the body portion and moveable between a first position and a second position, such that in the first position, the locking bar is in a locked configuration with respect to the first bore and in the second position, the locking bar is in an unlocked configuration with respect to the first bore, a locking sleeve slidably mounted on the plunger portion and moveable between a first position and a second position, such that in the first position, the locking sleeve is in a locked configuration with respect to the second bore, and in the second position, the locking sleeve is in an unlocked configuration with respect to the second bore, and a locking lever operably coupled to the body portion and configured to move between a first position and a second position to simultaneously transition the locking sleeve and the locking bar from the respective first positions to the respective second positions.

These and other examples and features of the present orthopedic device holders and kits will be set forth in part in the following Detailed Description. This Overview is intended to provide non-limiting examples of the present subject matter—it is not intended to provide an exclusive or exhaustive explanation. The Detailed Description below is included to provide further information about the present orthopedic device holder, kit, and method.
In the drawings, like numerals can be used to describe similar elements throughout the several views. Like numerals can be used to represent different views or configurations of similar elements. The drawings illustrate generally, by way of example, but not by way of limitation, various embodiments discussed in the present document.
The present orthopedic device holder (hereinafter referred to interchangeably as “device holder”) is configured to provide a quick and easy releasable connection for a plurality of orthopedic devices. The device holder can include a two-way connection such that the operator can select which connection configuration to use. The orthopedic device holder can also prove useful in applications to provide a securable, releasable connection for a plurality of different orthopedic devices used during an orthopedic procedure. The orthopedic device holder and its components can be made of a wide variety of materials, such as metal alloys, stainless steels, aluminum, titanium, polymers, or carbon fiber.
The plunger portion 14 can include a proximal end 24 and a distal end 26. As discussed herein, the plunger portion 14 can extend into a channel 36 of the body portion 4. The plunger portion 14 can define a second bore 28 of the body portion 4. As discussed herein, the first bore 10 and the second bore 28 have substantially identical cross-section geometries such that an orthopedic device can be interchangeably coupled to either the first bore 10 or the second bore 28.
The locking sleeve 16 can be slidably mounted on the plunger portion 14 and can be moveable between a first position and a second position. When the locking sleeve 16 is in the first position, the locking sleeve 16 can be in a locked configuration with respect to the second bore 28. When the locking sleeve 16 is in the second position, the locking sleeve 16 can be in an unlocked configuration with respect to the second bore 28.
The locking bar 18 can include a proximal end 32 and a distal end 30. In an example, the locking bar 18 can be operably coupled to the body portion 4. The locking bar 18 can be moveable between a first position and a second position. When the locking bar 18 is in the first position, the locking bar 18 can be in a locked configuration with respect to the first bore 10. When the locking bar 18 is in the second position, the locking bar 18 can be in an unlocked configuration with respect to the first bore 10.
The locking lever 22 can be operably coupled to the body portion 4. The locking lever 22 can operate as the single activation mechanism that connects and releases an orthopedic tool at each connection point (e.g., the first bore 10 and the second bore 28) of the device holder 2. The locking lever 22 can be configured to move between a first position and a second position. When the locking lever 22 moves from the first position to the second position (e.g., by a user pressing on the locking lever 22), the locking lever 22 can simultaneously transition the locking bar 18 and the locking sleeve 16 from the respective first positions to the respective second positions. Thus, a single activation can transition the orthopedic device holder 2 from a locked configuration to an unlocked configuration at each connection point.
The resilient member 20 can include a proximal end 19 and a distal end 21. The resilient member 20 can be positioned around the proximal end 24 of the plunger portion 14. Additionally, the resilient member 20 can be positioned between the locking sleeve 16 and an interior ledge 38 (as shown in
The body portion 4 can include at least one opening 40 in a side wall of the first bore 10. The at least one opening 40 can be configured such that it extends into an interior 48 of the first bore 10. In an example, the body portion 4 can include two openings 40 extending into the interior 48 of the first bore 10. In still another example, the body portion 4 can include more than two openings 40 extending into the interior 48 of the first bore 10. The body portion 4 can also define an indentation 50. As described herein, the indentation 50 can interact with the locking bar 18 as the locking lever 22 is transitioned from the first position to the second position. The body portion 4 can also define a locking hole 42 that can receive a locking bar 106 to lock the locking lever 22 to the body portion 4 (as shown in
As illustrated in
While the locking lever 22 is in the first position, the locking balls 94 can be positioned near a first end 91 of the ramped surface 92 and partially extend through the opening 56 in the plunger portion 14 and can fit into a mating recess of an orthopedic device. The engagement between the locking balls 94 and the mating recess of the orthopedic device can prevent axial movement of the orthopedic device. The ramped surfaces 92 can interact with the locking balls 94 as the locking lever 22 is transitioned from the first position (e.g., locked positioned) to the second position (e.g., unlocked position). For example, as the locking lever 22 transitions form the first position to the second position, the locking sleeve 16 can move relative to the plunger portion 14. As the locking sleeve 16 moves relative to the plunger portion 14, the relationship between the ramped surfaces 92 and the locking balls 94 changes such that the locking balls 94 are substantially positioned within a cavity 95 formed by the ramped surfaces 92. Thus, while the locking lever 22 is in the second position, the locking balls 94 are not positioned within the second bore 28 of the plunger portion 14 and do not engage the orthopedic device positioned within the second bore 28 (as shown in
As the locking sleeve 16 moves relative to the plunger portion 14, the ramped surfaces 92 of the locking sleeve 16 interact with the locking balls 94 such that the locking balls 94 are positioned within the cavity 95 formed by the ramped surfaces 92. In other words, the locking balls 94 are no longer engaging the openings 56 of the plunger portion 14. Similarly, as the locking bar 18 moves relative to the plunger portion 14, the ramped surfaces 102 of the locking bar 18 interact with the locking balls 74 such that the locking balls 74 are positioned within the cavity 103 formed by the ramped surfaces 102. In other words, the locking balls 74 are no longer engaging the openings 48 of the body portion 4.
As the locking lever 22 transitions to the second position, the locking arms 98 can move within the indentations 50 of the body portion 4. As the locking arms 98 move within the indentations 50, the relationship between the ramped surfaces 102 and the locking balls 74 changes such that the locking balls 74 are substantially positioned within a cavity 103 formed by the ramped surfaces 102, as shown in
As the locking lever 22 transitions to the second position, the locking sleeve 16 moves along the plunger portion 14. As the locking sleeve 16 moves along the plunger portion 14, the relationship between the ramped surfaces 92 and the locking balls 94 changes such that the locking balls 94 are substantially poisoned within a cavity 95 formed by the ramped surfaces 92, as shown in
