[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Combine the following Figure 1-Figure 6 The utility model describes a buckle structure and a surgical positioner assembly.

[0030] In the first aspect, Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a buckle structure 1, comprising: a buckle body 11 and a navigation mark 12; the buckle body 11 is configured to be snapped into a buckle hole 21 on a surgical positioning carrier 2, and the navigation mark 12 is arranged at at least one end of the buckle body 11 along the axial direction of the buckle hole 21.

[0031] It is understandable that the buckle body 11 may be an elastic member with a certain rigidity, and the buckle body 11 may be deformed when subjected to force, so that the buckle body 11 may be engaged in the engaging hole 21. Optionally, the buckle body 11 may be an injection molded part.

[0032] The navigation mark 12 may be a mark that can be recognized by an optical tracker, for example, the navigation mark 12 is a reflective sheet or a mark with a specific color or shape. The navigation mark 12 may be bonded to at least one end of the buckle body 11 by using adhesive (such as adhesive aid).

[0033] The clamping hole 21 can be a through hole or a blind hole provided on the surgical positioning carrier 2; the surgical positioning carrier 2 includes but is not limited to surgical instruments and auxiliary instruments used for surgery.

[0034] When the card hole 21 is a through hole, the navigation mark 12 can be set at one end or both ends of the buckle body 11 along the axial direction of the card hole 21. When the card hole 21 is a blind hole, the navigation mark 12 is set at one end of the buckle body 11 away from the bottom of the blind hole along the axial direction of the card hole 21.

[0035] In this way, when the buckle body 11 is buckled into the buckle hole 21 on the surgical positioning carrier 2, it can ensure that the navigation mark 12 is exposed on the surface of the surgical positioning carrier 2 so that the optical tracker can recognize the navigation mark 12 and further determine the position of the surgical positioning carrier 2.

[0036] As can be seen from the above, the buckle structure 1 can integrate the navigation mark 12 on the buckle body 11, so that the buckle body 11 can be conveniently clamped on the surgical positioning carrier 2 required for the operation. For example, the surgical positioning carrier 2 is a surgical instrument and an auxiliary instrument used for the operation. In actual applications, this design realizes the separate setting of the navigation mark 12 and the surgical instrument, which is convenient for the optical tracker to locate the surgical instrument according to the guidance provided by the navigation mark, and facilitates the reuse of the surgical instrument, which is beneficial to reducing the cost of surgery, reducing the scrap rate of surgical instruments and auxiliary instruments used for surgery, and further facilitating the promotion and application of surgical navigation.

[0037] In some embodiments, Figure 1 and Figure 2As shown, the buckle body 11 includes a cover body 111 and a plurality of clamping parts 112 ; the plurality of clamping parts 112 are disposed on a first end surface of the cover body 111 , and the plurality of clamping parts 112 are arranged in a circle relative to the center of the cover body 111 .

[0038] At the same time, Figure 5 and Figure 6 As shown, a clamping structure 211 is provided on the hole wall of the clamping hole 21 , and a plurality of clamping portions 112 are configured to be clamped with the clamping structures 211 respectively.

[0039] It is understandable that the operator presses the cover 111 to drive the cover 111 to drive the multiple engaging parts 112 to be inserted into the engaging hole 21 , and during the insertion process, the multiple engaging parts 112 are engaged with the engaging structures 211 on the hole wall of the engaging hole 21 .

[0040] Optionally, when the multiple clamping parts 112 are clamped with the clamping structure 211, the cover 111 covers the first end of the clamping hole 21, and the second end surface of the cover 111 is exposed on the surface of the surgical positioning carrier 2. The first end surface and the second end surface of the cover 111 are arranged opposite to each other.

[0041] Optionally, the clamping portion 112 is an elastic clamping piece that can undergo slight deformation, so as to achieve clamping between the clamping portion 112 and the clamping structure 211 .

[0042] Optionally, in order to meet the requirement of simultaneously engaging multiple engaging portions 112, the engaging structure 211 is an annular structure and is extended along the circumference of the engaging hole 21. The multiple engaging portions 112 can be arranged to be evenly distributed around the circumference relative to the center of the cover body 111.

[0043] Optionally, the clamping structure 211 may be an annular clamping groove provided on the hole wall of the clamping hole 21 , and a protrusion adapted to the annular clamping groove is provided on the clamping portion 112 .

[0044] Optionally, the clamping structure 211 can be an annular protrusion provided on the hole wall of the clamping hole 21, and the clamping portion 112 is provided with a clamping structure such as a clamping groove or a protrusion adapted to the annular clamping groove. In this way, when the multiple clamping portions 112 are inserted into the clamping hole 21, the multiple clamping portions 112 can be driven by the clamping structure 211 to move closer to each other until the multiple clamping portions 112 are respectively clamped with the clamping structure 211.

[0045] In some embodiments, Figure 1 As shown, a first end surface of the cover body 111 is provided with a limiting portion 1110 , which is radially located between the clamping portion 112 and the edge of the cover body 111 ; the limiting portion 1110 is configured to abut against the clamping hole 21 along the axial direction.

[0046] It is understandable that, during the process of inserting the buckle body 11 into the buckle hole 21 , the limiting portion 1110 of the cover body 111 can abut against the buckle hole 21 axially to limit the installation position of the buckle body 11 relative to the buckle hole 21 , thereby ensuring the stability of the installation of the buckle body 11 .

[0047] Optionally, the limiting portion 1110 can be a limiting surface arranged on the first end surface of the cover body 111, and the inner wall of the insertion end of the card hole 21 is provided with a step surface 212, at least part of the cover body 111 is embedded in the insertion end of the card hole 21, and the limiting surface of the cover body 111 can abut against the step surface 212 along the axial direction of the card hole 21.

[0048] In some embodiments, Figure 1 , Figure 2 and Figure 6 As shown, the clamping portion 112 includes a reinforcing section 1121 and a clamping section 1122 ; one end of the reinforcing section 1121 is connected to the first end surface of the cover body 111 , and the other end is connected to one end of the clamping section 1122 ; the clamping section 1122 is configured to clamp with the clamping structure 211 .

[0049] It is understandable that the locking hole 21 of the surgical positioning carrier 2 has a mating section and a locking section, the first end of the mating section is provided with a recessed groove, the bottom of the recessed groove is formed as the above-mentioned limiting surface, the second end of the mating section is connected to one end of the locking section, and the inner wall of the locking section is provided with a locking structure 211 extending along the circumferential direction.

[0050] The reinforcing section 1121 of the snap-fitting portion 112 and the matching section of the snap-fitting hole 21 correspond to each other, and the reinforcing section 1121 determines the stability between the snap-fitting body 11 and the surgical positioning carrier 2; the snap-fitting section 1122 of the snap-fitting portion 112 and the snap-fitting structure 211 of the snap-fitting section are snap-fitted, and the snap-fitting portion 112 determines that the snap-fitting body 11 is not easy to detach from the snap-fitting hole 21 of the surgical positioning carrier 2.

[0051] Therefore, by configuring the snap-fit ​​portion 112 as the reinforcement segment 1121 and the snap-fit ​​segment 1122 , the reliability and stability of the connection between the snap structure 1 and the surgical positioning carrier 2 can be ensured, which provides a guarantee for the safe use of surgical navigation.

[0052] In some examples, in order to ensure a tight fit between each clamping portion 112 and the clamping hole 21, the diameter of the peripheral wall of the plurality of clamping portions 112 can be set to be larger than the inner diameter of the clamping hole 21, and the fitting tolerance between the peripheral wall of the clamping portion 112 and the inner wall of the clamping hole 21 is S, and the value range of S is 0.01-0.03mm, for example, S can be 0.01mm, 0.02mm or 0.03mm.

[0053] In some examples, in order to ensure that the buckle body 11 is more firmly engaged in the engaging hole 21 , the dimensional tolerance gap corresponding to the reinforcement section in the engaging portion 112 may be set to be smaller than the dimensional tolerance gap corresponding to the engaging section.

[0054] In some embodiments, Figure 1 As shown, the gap width between the reinforcing sections 1121 of two adjacent clamping portions 112 is smaller than the gap width between the clamping sections 1122 of two adjacent clamping portions 112;

[0055] And / or, the reinforcing section 1121 and the clamping section 1122 of each clamping portion 112 are both extended along the circumferential direction of the cover body 111 , and the length of the reinforcing section 1121 extending along the circumferential direction is greater than the length of the clamping section 1122 extending along the circumferential direction.

[0056] It can be understood that multiple clamping parts 112 are arranged in sequence along the circumferential direction. By setting the gap width between the reinforcement sections 1121 of two adjacent clamping parts 112 to be smaller than the gap width between the clamping sections 1122 of two adjacent clamping parts 112, it can be ensured that the clamping section 1122 can have a larger movable space than the reinforcement section 1121, thereby facilitating the clamping between the clamping section 1122 and the clamping structure 211.

[0057] At the same time, when the plurality of clamping parts 112 are evenly distributed along the circumference, since the length of the reinforcing section 1121 extending along the circumference is greater than the length of the clamping section 1122 extending along the circumference, the gap width between the reinforcing sections 1121 of two adjacent clamping parts 112 will be smaller than the gap width between the clamping sections 1122 of two adjacent clamping parts 112. This design can ensure that the structural strength of the reinforcing section 1121 is greater than the structural strength of the clamping section 1122, so that the clamping section 1122 can achieve greater deformation flexibility than the reinforcing section 1121, and while maintaining the stability between the buckle body 11 and the surgical positioning carrier 2 based on the reinforcing section 1121, it is also convenient to use the clamping section 1122 to achieve reliable clamping between the buckle body 11 and the surgical positioning carrier 2.

[0058] In some embodiments, Figure 1 and Figure 6 As shown, the peripheral wall of the snap-fit ​​section 1122 is provided with a first protrusion, which extends along the circumference of the cover body 111 ; the snap-fit ​​structure 211 is a second protrusion extending along the circumference of the snap-fit ​​hole 21 , and the first protrusion is configured to snap-fit ​​with the second protrusion along the axial direction of the snap-fit ​​hole 21 .

[0059] It is understandable that a slot is formed between one end of the first protrusion facing the reinforcing section 1121 and the peripheral wall of the clamping section 1122. Since the first protrusion is arranged to extend along the circumference of the cover body 111, the slot is also arranged to extend along the circumference of the cover body 111, and the slot and the second protrusion are clamped to prevent the buckle body 11 from being separated from the clamping hole 21.

[0060] At the same time, by setting the second protrusion to extend along the circumference of the clamping hole 21, for example, the second protrusion can be set to be annular, this design can ensure that one second protrusion is clamped with multiple clamping parts 112 at the same time. In this way, in actual operation, there is no need to consider the posture of the clamp body 11 inserted into the clamping hole 21, that is, the clamping body 11 is directly inserted into the clamping hole 21 at any circumferential angle, and the clamping connection between the clamp structure 1 and the surgical positioning carrier 2 can be achieved, and the operation is simple and convenient.

[0061] Optionally, in order to facilitate the plugging operation of the buckle body 11 , the first protrusion can be provided at one end of the locking section 1122 away from the reinforcement section 1121 , and a guiding slope can be provided at one end of the first protrusion away from the reinforcement section 1121 .

[0062] During the clamping process, the guiding slope can ensure that the first protrusion passes through the surface of the second protrusion until the second protrusion is clamped in the clamping groove between the end of the first protrusion facing the reinforcing section 1121 and the peripheral wall of the clamping section 1122 .

[0063] In some embodiments, Figure 1 As shown, a navigation mark 12 is provided on the second end surface of the cover body 111 .

[0064] It is understandable that when the buckle body 11 is snapped into the buckle hole 21 on the surgical positioning carrier 2, the second end surface of the cover body 111 is exposed on the surface of the surgical positioning carrier 2. For example, the second end surface of the cover body 111 is flush with the first surface of the surgical positioning carrier 2. By setting the navigation mark 12 on the second end surface of the cover body 111, the optical tracker of surgical navigation can recognize the navigation mark 12 and accurately know the position of the surgical positioning carrier 2 based on the guidance provided by the navigation mark 12.

[0065] In some embodiments, Figure 1 and Figure 2 As shown, the buckle body 11 also includes a buckle body 113; the buckle body 113 is arranged on the first end surface of the cover body 111, and a plurality of snap-fitting parts 112 are arranged around the buckle body 113; the snap hole 21 is a through hole, the cover body 111 is configured to be arranged at the first end of the snap hole 21, and the buckle body 113 is configured to be exposed at the second end of the snap hole 21.

[0066] It is understandable that the buckle body 113 is columnar, and the buckle body 113 can be disposed at the center of the cover body 111 and coaxially arranged with the buckle structure formed by the plurality of buckle parts 112 .

[0067] The cover body 111, multiple snap-on parts 112 and the snap-on body 113 can be integrally injection molded. A certain radial gap needs to be reserved between the peripheral wall of the snap-on body 113 and the inner wall of the snap-on part 112 to meet the deformation requirements of the snap-on part 112, thereby facilitating the snap-on connection between the snap-on part 112 and the snap-on structure 211.

[0068] like Figure 3 and Figure 4 As shown, since the latch hole 21 is a through hole, when disassembling the latch structure 1, pressure can be applied to the end of the latch body 113 that is away from the cover body 111, and the cover body 111 transmits the pressure to each latching part 112, so that the latching part 112 is deformed and disengaged from the latching structure 211 on the hole wall of the latch hole 21. At this time, you only need to take the latch structure 1 out of the latch hole 21, and the operation is simple and convenient.

[0069] In some embodiments, Figure 1 As shown, a navigation mark 12 is provided at one end of the buckle body 113 away from the cover body 111 .

[0070] It is understandable that one end of the buckle body 113 away from the cover body 111 is exposed at the second end of the buckle hole 21, which makes the end of the buckle body 113 away from the cover body 111 exposed to the second surface of the surgical positioning carrier 2. For example, the end of the buckle body 113 away from the cover body 111 is flush with the second surface of the surgical positioning carrier 2. At this time, a navigation mark 12 is set at the end of the buckle body 113 away from the cover body 111 to facilitate the optical tracker of surgical navigation to identify the navigation mark 12.

[0071] In the second aspect, Figure 3 , Figure 4 and Figure 5 As shown, the embodiment of the utility model further provides a surgical positioning device assembly, including: a surgical positioning carrier 2 and the above buckle structure 1; the surgical positioning carrier 2 is provided with a buckle hole 21, and the buckle body 11 of the buckle structure 1 is buckled in the buckle hole 21.

[0072] It is understandable that the surgical locator assembly includes but is not limited to surgical instruments and auxiliary instruments used for surgery, which instruments may be implant mobile phone locators, calibration locators, end locators, etc.

[0073] At the same time, in order to ensure more accurate detection of the position of the surgical positioning carrier 2, a plurality of snap holes 21 are provided on the surgical positioning carrier 2, and a plurality of snap structures 1 are provided, and the snap bodies 11 of the plurality of snap structures 1 are snapped into the plurality of snap holes 21 one by one.

[0074] Since the surgical locator assembly includes a snap structure 1, and the specific structure of the snap structure 1 refers to the above embodiment, the surgical locator assembly shown in this embodiment includes all the technical solutions of the above embodiment, and therefore, at least has all the beneficial effects achieved by all the technical solutions of the above embodiment, which will not be repeated here one by one.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
