[0036] The utility model provides an interlocking mechanism of an implantation tool, which comprises a shell, a driving button, and a ejection piece; an elastic cantilever is arranged in the shell; the driving button is arranged on the shell; the ejection piece comprises a ejection piece body, a pushing part, and a buckle part, and the pushing part and the buckle part are respectively arranged on the ejection piece body; the pushing part is arranged corresponding to the driving button, and is used for pushing the driving button to move relative to the shell, so that the driving button squeezes and limits the elastic cantilever, so that the elastic cantilever buckles the buckle part. In the interlocking mechanism of the implantation tool, the pushing part is provided on the ejection piece. When the ejection piece is installed in the shell, the driving button can be driven to move by the pushing part, so that the driving button squeezes and restricts the elastic cantilever in the shell, and then the ejection piece is snapped onto the shell through the elastic cantilever. During assembly, only the ejection piece needs to be pushed to complete the installation and positioning of the driving button and the snap-on installation of the ejection piece, which can simplify the number of parts and realize the locking and disengagement freedom of the ejection piece. At the same time, it can also make the assembly process simpler, reduce the assembly difficulty, and improve the assembly efficiency.

[0037] Please refer to Figures 1 to 4 The present embodiment provides an interlocking mechanism 100 of an implantation tool, which includes a housing 10, a driving button 20, and a push piece 30. The housing 10 is provided with an elastic cantilever 40, and the driving button 20 is provided on the housing 10. The elastic cantilever 40 refers to a component that can undergo elastic deformation after being subjected to force, and can restore its state when the force is reduced or eliminated.

[0038] The ejection member 30 includes an ejection member body 31, a pushing portion 32, and a buckle portion 33, wherein the pushing portion 32 and the buckle portion 33 are respectively arranged on the ejection member body 31. The pushing portion 32 is arranged corresponding to the driving button 20, and the pushing portion 32 is used to push the driving button 20 to move relative to the housing 10, so that the driving button 20 squeezes the elastic cantilever 40 to limit the position, so that the elastic cantilever 40 buckles the buckle portion 33. In other words, the pushing portion 32 is used to push the driving button 20 to move, so that the driving button 20 moves to a desired position, and the driving button 20 after the movement will squeeze the elastic cantilever 40 correspondingly, and the elastic cantilever 40 squeezed by the driving button 20 will block the buckle portion 33 correspondingly, so that the ejection member 30 is buckled on the elastic cantilever 40, so as to realize the buckle connection between the ejection member 30 and the housing 10.

[0039] When the ejection member 30 is installed into the housing 10, Figure 1As shown, before the assembly is pushed, the driving button 20 is in a depressed state. When the ejection member 30 is pushed, the end surface of the pushing portion 32 will push against the bottom surface of the driving button 20. At this time, the ejection member 30 will push the driving button 20 until the ejection member 30 is pushed to the stop end surface 101 of the housing 10 and stops moving (as shown in FIG. Figure 2 When the ejection member 30 stops advancing, the ejection member 30 moves downward under the elastic force of the ejection spring 50 until the buckle portion 33 contacts the elastic cantilever 40 and stops moving downward. Since the elastic cantilever 40 is blocked from deforming by the driving button 20, the elastic cantilever 40 cannot deform, and the elastic cantilever 40 blocks the buckle portion 33, thereby buckling the ejection member 30 on the housing 10.

[0040] When the implantation tool is used, the operator only needs to press the drive button 20, and the drive button 20 will give the elastic cantilever 40 a deformation space, so that the elastic cantilever 40 can smoothly retreat and deform, so that the ejection member 30 is detached from the elastic cantilever 40.

[0041] The interlocking mechanism 100 of the implant tool provided in this embodiment can simplify the structure of the implant tool, reduce the number of parts in the implant tool, and realize the locking and disengagement freedom of the ejection piece 30, while also simplifying the assembly process. During the assembly process, the ejection piece 30 can be pushed to complete the installation and positioning of the drive button 20 and the snap-fit ​​installation between the ejection piece 30 and the shell 10, thereby reducing the difficulty of assembly and improving the assembly efficiency.

[0042] Preferably, in one embodiment, the driving button 20 includes a button body 21 and a button buckle 22 disposed at the bottom of the button body 21, and the button buckle 22 is used to squeeze and limit the elastic cantilever 40. The pushing portion 32 is disposed corresponding to the button buckle 22, and is used to push the button buckle 22. That is to say, in this embodiment, the pushing portion 32 is specifically used to push the button buckle 22, thereby driving the driving button 20 to move as a whole. At the same time, the driving button 20 also squeezes and limits the elastic cantilever 40 through the button buckle 22 disposed at the bottom, so as to buckle the ejection member 30.

[0043] Preferably, in one embodiment, the button button 22 is located on the inner side of the elastic cantilever 40, and the buckle portion 33 is located on the outer side of the elastic cantilever 40. The inner side of the elastic cantilever 40 refers to the side of the elastic cantilever 40 that is relatively close to the central axis of the housing 10, and correspondingly, the outer side of the elastic cantilever 40 refers to the side of the elastic cantilever 40 that is relatively far away from the central axis of the housing 10. In this embodiment, the button button 22 squeezes and limits the elastic cantilever 40 on the inner side of the elastic cantilever 40, so that the elastic cantilever 40 deforms outward, thereby buckling the buckle portion 33. When the operator presses the drive button 20, the elastic cantilever 40 will deform inward and recover by its own elasticity.

[0044] Preferably, in one embodiment, the elastic cantilever 40 includes a connecting arm 41 and a clamping platform 42, and the connecting arm 41 is connected to the housing 10. The clamping platform 42 is arranged at the bottom of the connecting arm 41 to abut against and limit the buckle portion 33. That is to say, in this embodiment, the elastic cantilever 40 specifically limits the buckle portion 33 through the clamping platform 42, so that the ejection member 30 is clamped on the housing 10.

[0045] Preferably, in one embodiment, the inner surface of the buckle portion 33 (the surface close to the central axis of the housing 10) is provided with a hanging platform 331, and the clamping platform 42 is used to abut against and limit the hanging platform 331 to buckle the buckle portion 33. Through this structure, the reliability of the buckle connection between the ejection member 30 and the elastic cantilever 40 can be better guaranteed, and the ejection member 30 can be better prevented from accidentally slipping off.

[0046] More preferably, in one embodiment, the first surface 3311 of the hanging platform 331 for abutting against the card platform 42 and the second surface 421 of the card platform 42 for abutting against the hanging platform 331 are both inclined surfaces, and the moving direction ( Figure 3 The two inclined surfaces are inclined away from the central axis of the housing 10. The two inclined surfaces are arranged so that after the operator drives the button 20, the ejection member 30 can be separated from the elastic cantilever 40 more smoothly.

[0047] Preferably, in one embodiment, a guide slope 422 is provided on one side of the bottom of the card platform 42 close to the button button 22. When the ejection member 30 is pushed into the housing 10, the top surface of the push portion 32 contacts the guide slope 422, and the elastic cantilever 40 can be better guided by the guide slope 422, so that the elastic cantilever 40 is deformed outward, reducing the difficulty of pushing the ejection member 30.

[0048] Preferably, in one embodiment, the elastic cantilever 40 is provided with a plurality (at least two), and all the elastic cantilevers 40 are distributed in the shell 10 in an annular shape, that is, all the elastic cantilevers 40 are distributed in the shell 10 in an annular shape as a whole. Each of the elastic cantilever 40 is provided with a button buckle 22 and a buckle portion 33. That is, a button buckle 22 is provided on the inner side of each elastic cantilever 40, and a buckle portion 22 is provided on the outer side, so that the forces on each side between the driving button 20, the ejection member 30, and the elastic cantilever 40 can be more balanced. For example, in one embodiment, two elastic cantilevers 40 can be provided, and the two elastic cantilevers 40 can be arranged opposite to each other with the central axis of the shell 10 as the center interval.

[0049] Please refer to Figure 5 Meanwhile, in one embodiment, an implantation tool 1000 is also provided, which includes the interlocking mechanism 100 of the implantation tool, a transmitter 200, a sensor 300, and an implantation needle assembly 400. The transmitter 200 is detachably arranged on the ejection member 30, the sensor 300 is arranged on the transmitter 200, and the implantation needle assembly 400 is buckled on the ejection member 30.

[0050] The above is only an implementation method of the present invention. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements are within the protection scope of the present invention.
