[0002] With the development of medical technology, navigation systems have been used in surgery to better assist surgeons in performing surgery. In some navigation surgeries, optical tracers are usually used to navigate and track some surgical instruments to determine their positions, so that surgical operations can be performed under real-time navigation display. However, many commonly used supporting instruments in surgery do not have navigation functions, especially some instruments with higher operating risks. They need to be operated in some high-risk areas of clinical operations, such as areas near nerves. These high-risk operations often test the surgeon's clinical experience. In addition, during surgery, when the navigation function is not needed, the relevant instruments may affect the surgeon's operation. Utility Model Content

[0028] In the following description, the descriptions about directions, such as "upper", "lower", "inner", "outer", "radial", "axial", etc., which may be used, are only for the convenience of description, unless otherwise specified, and are not intended to form any limitation on the technical solution of the utility model. In addition, in the following description, terms such as "first", "second", etc. are used to describe the elements of the present application, and these terms are only used to distinguish the elements, and are not intended to limit the nature, sequence, order or number of these elements.

[0029] Figure 1 An overall schematic diagram of a connection device with a quick-change interface according to the utility model is shown. Figure 2FIG. 1 shows a first cross-sectional view of a connection device with a quick-change interface according to the present utility model. Figure 1 and Figure 2 As shown, the connection device with a quick-change interface of the present invention has an interface body 1, and the interface body 1 has a first part, for example, a columnar shape, and a second part and a third part extending from the first part. As an example, Figure 1 As shown, the interface body is generally in an inverted Y-shape or T-shape. On the first part, an interface 1a is provided for connecting with the component to be connected. The second part and the third part are respectively connected with two clamping parts to be described below.

[0030] The interface body 1 also has a through hole for the adjustment component 4 to pass through. Figure 2 As shown, the middle part of the adjusting component 4 is not provided with threads, and is supported inside the through hole of the interface body 1, and can rotate around its own axis, but cannot move along its axis. Specifically, the middle part of the adjusting component 4 is blocked by the interface body 1, and thus cannot move axially. Preferably, a first operating part 5 is provided at one end of the adjusting component 4. On both sides of the first part, a first movable part 2 and a second movable part 3 are provided, respectively. Connecting parts are provided inside the first movable part 2 and the second movable part 3, respectively, so that when the adjusting component 4 is rotated by the first operating part 5, the adjusting component 4 can rotate to drive the first movable part 2 and the second movable part 3 to move along the axis of the adjusting component 4.

[0031] As a specific implementation method, see Figure 2 , the connecting pieces in the first movable part 2 and the second movable part 3 have internal threads. Correspondingly, two sections of external threads are provided on the adjusting part 4, and the two sections of external threads are respectively engaged with the internal threads of the connecting pieces in the first movable part 2 and the second movable part 3. Further, the rotation directions of the internal threads on the connecting pieces in the first movable part 2 and the second movable part 3 are opposite, so that when the adjusting part 4 rotates, the first movable part 2 and the second movable part 3 move in opposite directions. The first movable part 2 and the second movable part 3 are respectively fixedly connected to the first clamping part 6 and the second clamping part 7, and the first clamping part 6 and the second clamping part 7 can be rotated by the rotating shafts provided on the second part and the third part of the interface body 1, respectively. Therefore, when the first movable part 2 and the second movable part 3 move axially, they will also drive the first clamping part 6 and the second clamping part 7 to rotate around the rotating shaft, thereby realizing the approach or distance of the two clamping parts, thereby realizing the clamping or loosening of the parts.

[0032] like Figure 1As shown, since the first movable part 2 and the second movable part 3 need to rotate around the rotating shaft located on the second part and the third part when moving along the axial direction of the adjusting component 4, a spherical accommodation space is provided inside the first movable part 2 and the second movable part 3. Correspondingly, the outer contour of the connecting member also has a spherical surface. As a result, relative rotation can occur between the connecting member and the movable part. As a result, when the connecting member moves axially through the threaded connection, it can drive the movable part to move while also causing the movable part to rotate around the rotating shaft provided on the second part and the third part of the interface body 1.

[0033] As an improvement of the utility model, Figure 1 As shown, an interface 1a is provided on the first part of the interface body 1 for connecting with the component to be connected. A receiving portion 1b is also provided on the first part for receiving components such as a locking portion and a spring to be described below.

[0034] Figure 3 A second cross-sectional view of a connection device with a quick-change interface according to the present utility model is shown. Figure 1 , Figure 2 and Figure 3 In the receiving portion 1b, a locking portion 9 is provided. The locking portion 9 has a main body, for example, which is cylindrical and thus defines an axis, and a conical portion 9a is provided on the main body. Preferably, a second operating portion 8 is provided at one end of the main body of the locking portion 9, so that the locking portion 9 can be moved along its own axis direction by the second operating portion 8. Furthermore, a cover 10 is also provided at one end of the receiving portion 1b. Figure 3 As shown, an elastic member 11 is further provided in the accommodating portion 1b. The elastic member 11 is a coil spring, one end of which abuts against the surface of the cover 10, and the other end abuts against the bottom surface of the tapered portion 9b perpendicular to the axis of the locking portion 9. In the first state, the second operating portion 8 is not operated, so the elastic member 11 is not subjected to the force from the operator.

[0035] Figure 4 An overall schematic diagram of the connection device with a quick-change interface according to the utility model and other components is shown. Figure 5 A cross-sectional view of the connection device with a quick-change interface according to the present invention connected to other components is shown. Figure 4 and Figure 5 ,and Figures 1 to 3 The difference is that the connection device with a quick-change interface of the present invention is connected to the component to be connected 12 through its interface 1a. Figure 5 It can be seen from FIG. 1 that the component to be connected 12 has a surface that matches the tapered surface of the tapered portion 9a.

[0036] During use, by pressing the second operating portion 8, the locking portion 9 can be moved along its own axis, thereby making room for the corresponding connecting portion on the component to be connected 12. When the corresponding connecting portion on the component to be connected 12 enters the interface 1a and matches the conical surface of the conical portion 9a, the connection between the connecting device and the component to be connected 12 can be achieved. At this time, the elastic member 11 can apply a greater force to the conical portion 9a, so that the conical portion 9a is more tightly connected to the corresponding portion of the component to be connected 12.

[0037] Although the tapered portion 9a is used as an example in the above exemplary embodiment, other shapes of structures may be provided to connect with the corresponding portion on the component to be connected 12. For example, a toothed connection may be adopted, that is, the tapered portion 9a in the figure is replaced with a toothed structure, which may be engaged with a matching toothed structure on the component to be connected 12, thereby achieving connection between the connecting device and the component to be connected 12.

[0038] As a specific application scenario, in use, the user can adjust the distance between the first clamping part 6 and the second clamping part 7 by rotating the first operating part 5, so as to clamp or disengage different medical devices to meet surgical needs. By pressing the second operating part 8, the connection with other components such as an optical tracer can be quickly achieved, so that the optical tracer can be used; or the optical tracer can be quickly removed by pressing the second operating part 8, so as to avoid interference with the tracer surgeon or other operators. The medical device clamped between the two clamping parts can be, for example, a rigid surgical tool such as a power tool handle, an ultrasonic bone knife handle, or a borescope handle, and the tracer is connected to the quick-change interface on the interface body, so that the position of these surgical tools can be determined by the tracer.

[0039] The above is a detailed description of the specific structure of the utility model. As can be seen from the above, the utility model proposes a connection device with a quick-change interface, which can use the first operating part to adjust the distance between the two clamping parts so as to be fixed with different medical devices, and use the second operating part to quickly connect or remove the tracer. Therefore, through the connection device of the utility model, different types of instruments can be connected on the one hand, and the tracer can be connected on the other hand, so as to realize intraoperative navigation, assist the surgeon to complete the surgical operation more safely and accurately, and also enable the surgeon to remove the optical tracer at any time during the operation to avoid the interference of the tracer with the surgeon's operation.
