[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0026] According to an embodiment of the present utility model, a connection structure is provided. Figures 1 to 4, including: a mounting component 10, a clamping portion 1 is provided on the outer surface of the mounting component 10, the clamping portion 1 includes a protruding fixing block 11 and an abutting portion 12 provided on the fixing block 11; a mounting seat 20, the mounting seat 20 includes a mounting groove 201, the mounting groove 201 is used to accommodate the mounting component 10; a first limiting portion 2 is protrudingly provided on the inner wall surface of the mounting groove 201, the first limiting portion 2 is provided with an opening 21 for the clamping portion 1 to pass through, and a clamping groove 22 is provided on one side of the first limiting portion 2 close to the bottom of the mounting groove 201, the clamping groove 22 abuts against the abutting portion 12 to prevent the mounting component 10 from leaving the mounting groove 201.

[0027] By setting the first limiting portion 2 and the clamping portion 1, an opening 21 is set on the first limiting portion 2, so that the clamping portion 1 can pass through the first limiting portion 2, so that the clamping portion 1 and the mounting component 10 as a whole enter the mounting groove 201, and the mounting component 10 is rotated to make the abutting portion 12 abut against the clamping groove 22, which can prevent the mounting component 10 from leaving the mounting groove 201 as a whole, thereby completing the connection between the mounting component 10 and the mounting seat 20, realizing the rapid installation of the mounting component 10 and the mounting seat 20, making the installation and disassembly process simpler and more labor-saving, and solving the technical problem of poor disassembly efficiency of the reflective ball seat in the related technology.

[0028] Specifically, the engaging groove 22 includes a first engaging surface and a second engaging surface, a certain angle is set between the first engaging surface and the second engaging surface, and the first engaging surface and the second engaging surface are respectively in abutment with the abutment portion 12, that is, the engaging groove 22 is in a "V" shape.

[0029] In the connection structure of this embodiment, see Figure 2 The abutment portion 12 is protruding from the fixing block 11, and the abutment portion 12 is embedded in the clamping groove 22. Through the above arrangement, the abutment portion 12 is embedded in the clamping groove 22, which can limit the relative position of the mounting component 10, so as to prevent the mounting component 10 from sliding relative to the first limiting portion 2 or preventing the mounting component 10 from rotating circumferentially, so that the mounting component 10 and the mounting seat 20 maintain a stable connection relationship.

[0030] In some embodiments, the abutting surface of the abutting portion 12 is configured as a smooth arc-shaped surface.

[0031] In some embodiments, the abutting portion 12 is a hemispherical structure.

[0032] It is understandable that the abutment portion 12 adopts a smooth arc surface or a hemispherical structure, which can achieve automatic centering, so that the abutment portion 12 automatically enters the engaging groove 22 and quickly completes the engaging of the abutment portion 12 and the engaging groove 22 .

[0033] In the connection structure of this embodiment, see Figure 3The first position-limiting portion 2 includes a first guide surface 23, and a certain angle is set between the extension direction of the first guide surface 23 and the extension direction of the first position-limiting portion 2, and the abutting portion 12 is slidably arranged relative to the first guide surface 23. By setting the first guide surface 23, the abutting portion 12 is avoided when the mounting component 10 rotates, so as to avoid the abutting portion 12 from colliding with the first position-limiting portion 2, so that the abutting portion 12 can smoothly enter the clamping groove 22.

[0034] Specifically, the first guide surface 23 is spaced apart from the engaging groove 22 . When the mounting component 10 rotates, the abutting portion 12 passes through the first guide surface 23 and enters the engaging groove 22 .

[0035] In the connection structure of this embodiment, see Figure 3 The mounting seat 20 includes a guide step 3 arranged on the inner wall surface of the mounting groove 201, and the guide step 3 includes a second guide surface 31, and the second guide surface 31 is arranged corresponding to the opening 21; a sliding surface 111 is arranged on the side of the fixed block 11 away from the abutment portion 12, and the sliding surface 111 and the second guide surface 31 are slidably arranged relative to each other.

[0036] Specifically, a certain angle is set between the extension direction of the second guide surface 31 and the axial direction of the mounting groove 201, so that the mounting component 10 is guided when the mounting component 10 rotates. When the clamping portion 1 enters the mounting groove 201 through the opening 21, the mounting component 10 rotates and the sliding surface 111 and the second guide surface 31 slide relative to each other, so that the mounting component 10 moves along the second guide surface 31 toward the bottom of the mounting groove 201, thereby moving the abutment portion 12 to the bottom of the clamping groove 22.

[0037] Specifically, the guide step 3 is protrudingly arranged on the inner wall surface of the mounting groove 201, and the guide step 3 includes a circumferential limit surface, and the extension direction of the circumferential limit surface is parallel to the axial direction of the mounting groove 201. The same mounting component 10 includes multiple clamping parts 1. By calculating the distance and number of the clamping parts 1, a clamping part 1 is set as a circumferential stop for the rotational movement of the mounting component 10, that is, when the mounting component 10 rotates, any one of the clamping parts 1 slides relative to the second guide surface 31. When the clamping part 1 serving as the circumferential stop hits the circumferential limit surface, the mounting component 10 stops rotating, and the abutment part 12 moves just to the bottom of the clamping groove 22, thereby realizing the clamping connection between the abutment part 12 and the clamping groove 22.

[0038] Specifically, the guide step 3 is connected to the bottom surface of the mounting groove 201 , and the distance between the second guide surface 31 and the bottom surface of the mounting groove 201 gradually decreases toward the direction approaching the bottom surface of the mounting groove 201 .

[0039] In the connection structure of this embodiment, see Figure 1 and Figure 4 The mounting seat 20 includes a second limiting portion 4, which is located at a side of the mounting seat 20 away from the first limiting portion 2, and abuts against the mounting component 10. The second limiting portion 4 is telescopically arranged along the axial direction of the mounting groove 201. By providing the second limiting portion 4, the second limiting portion 4 abuts against the bottom of the mounting component 10, so that the abutting portion 12 is pressed against the clamping groove 22, thereby locking the mounting component 10 in the mounting seat 20.

[0040] Specifically, the second limiting portion 4 is telescopically arranged along the axial direction of the mounting groove 201, that is, the second limiting portion 4 can move up and down along the axial direction of the mounting groove 201, thereby satisfying the requirement of the mounting component 10 to move up and down, so that the mounting component 10 can move back and forth in the height direction along the second guide surface 31; when the clamping portion 1 serving as a circumferential stop hits the circumferential limiting surface, the mounting component 10 stops rotating, and the abutment portion 12 moves to the bottom of the clamping groove 22. Through the upward movement of the second limiting portion 4, the abutment portion 12 can enter the clamping groove 22, so that the clamping groove 22 is clamped with the abutment portion 12.

[0041] When the connection structure in this embodiment is applied to the tracker bracket, the mounting component 10 is locked in the mounting seat 20, which can prevent the luminous ball seat from rotating and shaking in the mounting seat 20, thereby improving the connection stability between the luminous ball seat and the tracker bracket, avoiding the phenomenon of inaccurate positioning of surgical tools during surgery, improving the success rate of the surgery, and avoiding affecting the progress of the surgery.

[0042] In the connection structure of this embodiment, see Figure 4 The second limiting part 4 includes: an elastic member 41; a limiting cover 42, one side of the limiting cover 42 abuts against the mounting component 10, and the other side of the limiting cover 42 abuts against the elastic member 41. By providing the elastic member 41, the reciprocating movement requirement of the second limiting part 4 can be met, and the second limiting part 4 can be automatically reset after the mounting component 10 is pressed by a person's hand.

[0043] In the connection structure of this embodiment, see Figure 4 The mounting seat 20 comprises: a bottom plate 202, the bottom plate 202 is located at the bottom of the mounting groove 201, an adjustment opening 203 and an adjustment hole 204 are provided on the bottom plate 202, a limit cover 42 is inserted into the adjustment opening 203, the adjustment hole 204 is connected with the mounting groove 201 through the adjustment opening 203, and the limit cover 42 is movably arranged in the adjustment hole 204 along the axis direction of the mounting groove 201; and a cover plate 205, the cover plate 205 is arranged on the adjustment hole 204, and the cover plate 205 is in contact with the elastic member 41. By setting the adjustment opening 203 and the adjustment hole 204, the limit cover 42 and the elastic member 41 can be limited.

[0044] In the connection structure of this embodiment, see Figure 4 The limit cover 42 is provided with a baffle 421, which abuts against the adjustment opening 203 to limit the limit cover 42. By providing the baffle 421 to limit the relative position of the limit cover 42, the limit cover 42 and the elastic member 41 maintain a stable assembly relationship.

[0045] Preferably, the mounting component 10 is a cylindrical structure, and the mounting groove 201 is a circular groove body.

[0046] In the connection structure of this embodiment, see Figure 2-3 The first limiting portion 2 is annular; the clamping portion 1 includes a plurality of clamping portions 1 arranged in an array around the axis of the mounting groove 201; the opening 21, the first guide surface 23 and the clamping groove 22 are each provided with a plurality of corresponding ones. Through the above arrangement, the connection stability between the mounting component 10 and the mounting seat 20 is improved.

[0047] Preferably, the clamping parts 1 include three, and the three clamping parts 1 are evenly distributed on the outer wall surface of the mounting component 10, and the opening 21, the first guide surface 23 and the clamping groove 22 are all set to three

[0048] Preferably, in this embodiment, only one guide step 3 is provided.

[0049] The method of using the connection structure in this embodiment is as follows:

[0050] 1. Place the mounting component 10 on the mounting seat 20 , align the clamping portion 1 with the opening 21 , insert the mounting component 10 into the mounting groove 201 , press down the mounting component 10 manually and make the mounting component 10 rotate and slide clockwise along the second guide surface 31 .

[0051] 2. When the abutment portion 12 moves to the bottom of the snap-in groove 22, the installation component 10 stops rotating, the human hand releases, the second limit portion 4 automatically resets and abuts against the bottom of the installation component 10, and the installation component 10 moves upward to make the abutment portion 12 abut against the snap-in groove 22, completing the installation of the installation component 10.

[0052] 3. When removing the installation component 10, the person manually presses the installation component 10 downward again and rotates the installation component 10 in the opposite direction, so that the abutment portion 12 leaves the clamping groove 22, and the installation component 10 rotates counterclockwise along the second guide surface 31 so that the clamping portion 1 is aligned with the opening 21. At this time, the installation component 10 can be separated from the installation groove 201, and the removal of the installation component 10 is completed.

[0053] In the tracker bracket of this embodiment, see Figure 1 The tracker bracket includes a connecting structure for mounting a reflective ball seat, and the connecting structure is the above-mentioned connecting structure.

[0054] The connection structure in this embodiment is applied to the tracker bracket, the mounting component 10 is combined with the reflective ball seat, and the mounting seat 20 is arranged on the tracker bracket, so that the mounting component 10 is easy to install. Only by pressing and rotating the mounting component 10 can the automatic positioning and locking be completed synchronously, thereby realizing the rapid disassembly and assembly of the reflective ball seat and the tracker bracket, improving the installation efficiency of the reflective ball seat, and making the installation and disassembly process more convenient, fast, simple and practical, with a high safety factor. As long as the mounting component 10 is not pressed down and rotated, the mounting component 10 cannot be detached by itself, has a strong adaptability to surgical procedures with large vibrations, and has a high structural reliability, thereby ensuring the normal progress of the operation.
