[0023] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.
[0024] In the existing scheme, in order to effectively adjust the osteotomy guide plate to adapt to the osteotomy operation on the target affected part, an adjustment structure is usually added to the osteotomy guide plate, for example, a forward and backward tilt adjustment structure is added to the osteotomy guide plate, or a swing angle adjustment structure is added to the osteotomy guide plate, or a telescopic adjustment structure is added to the osteotomy guide plate, or a combination of at least two of the aforementioned adjustment structures. However, in the existing adjustment structure that simultaneously realizes the tilt angle, swing angle and telescopic adjustment of the osteotomy guide plate, since its structure usually adopts the method of integrating the structure into a single structural member, it is easy to cause the range of movement of the structural member to be small, and then the amplitude of the osteotomy guide that can be adjusted by the structure as a whole is small. Therefore, the small adjustment amplitude of the osteotomy guide plate has become a problem that needs to be solved urgently.
[0025] In order to solve the aforementioned problems, the present application provides an osteotomy guide 10 . Figure 1 FIG. 1 is a schematic diagram showing the structure of the osteotomy guide 10. Figure 1 As shown, the osteotomy guide 10 includes: an osteotomy guide plate portion 11, a telescopic portion 12, a fixing portion 13, a hinge portion 14, an inclination angle adjustment portion 15 and a swing angle adjustment portion 16.
[0026] The hinge part 14 is hinged with the telescopic part 12 to form a first hinge axis D1 around which they rotate. The first hinge axis D1 is consistent with the depth direction of the osteotomy groove 111 of the osteotomy guide plate part 11. The hinge part 14 is hinged with the osteotomy guide plate part 11 to form a second hinge axis D2 around which they rotate. Figure 2The right side view of the osteotomy guide 10 is shown, with reference to Figure 2 As shown, the second hinge axis D2 is consistent with the length direction of the osteotomy groove 111 of the osteotomy guide plate part 11.
[0027] in, Figure 2 The first direction Y is shown in FIG. The first direction Y is the depth direction of the osteotomy groove 111. The first hinge axis D1 is consistent with the depth direction of the osteotomy groove 111, that is, the first hinge axis D1 is consistent with the direction of the first direction Y, that is, the first hinge axis D1 extends along the first direction Y. After being hinged, the hinged portion 14 and the telescopic portion 12 can both rotate around the first hinge axis D1. Similarly, Figure 1 , the second direction X is shown in FIG. The second direction X is the length direction of the osteotomy groove 111. The second hinge axis D2 is consistent with the length direction of the osteotomy groove 111, that is, the second hinge axis D2 is consistent with the direction of the second direction X, that is, the second hinge axis D2 extends along the second direction X. After being hinged, the hinge portion 14 and the osteotomy guide plate portion 11 can both rotate around the second hinge axis D2.
[0028] It should be noted that the aforementioned first hinge axis D1 is consistent with the first direction Y, and the second hinge axis D2 is consistent with the second direction X. It is not required that the first hinge axis D1 is completely consistent with the first direction Y, nor is it required that the second hinge axis D2 is completely consistent with the second direction X. They only need to be basically consistent. For example, there may be an angle of less than or equal to 10 degrees between the first hinge axis D1 and the first direction Y, and between the second hinge axis D2 and the second direction X, but it is not limited thereto. The first hinge axis D1 is basically consistent with the first direction Y, and the second hinge axis D2 is basically consistent with the second direction X, which can be flexibly selected according to actual needs.
[0029] The fixing portion 13 is used to be fixed relative to other structures of the osteotomy guide 10. The telescopic portion 12 includes a first telescopic portion 121 and a second telescopic portion 122. The first telescopic portion 121 passes through the fixing portion 13 and can move relative to the fixing portion 13 along a direction passing through the fixing portion 13.
[0030] Among them, the fixing part 13 is used to remain fixed relative to other structures of the osteotomy guide 10, that is, when the osteotomy guide 10 is used, the fixing part 13 can be fixed to other structures used as a reference, such as the moving end of the robotic arm of a surgical robot, or the fixing part 13 can be directly held by hand to achieve the adjustment of the inclination angle, swing angle and telescopic amount based on the fixing part 13 as a reference.
[0031] and, Figure 1 and Figure 2The third direction Z is also shown in the figure. The third direction Z is the direction passing through the fixing portion 13. The first telescopic portion 121 can move relative to the fixing portion 13 along the direction passing through the fixing portion 13, that is, the first telescopic portion 121 can move relative to the fixing portion 13 along the third direction Z. By the movement of the first telescopic portion 121 along the third direction Z, the hinged portion 14 hinged to the telescopic portion 12 can be driven, and then the osteotomy guide plate 112 hinged to the hinged portion 14 can be driven, so as to adjust the telescopic amount of the osteotomy guide plate 112.
[0032] refer to Figure 8 The structural schematic diagram of the swing angle adjustment part 16 is shown, and the swing angle adjustment part 16 includes a swing angle adjustment button 161, a swing angle adjustment rod 162 and a swing angle connecting member 163. The swing angle adjustment button 161 is installed on the second telescopic part 122 and can rotate in the direction around the first hinge axis D1. The hinge part 14 is provided with a swing groove 141. The swing angle adjustment rod 162 is parallel to the first hinge axis D1 and matches the swing groove 141. The swing angle connecting member 163 connects the swing angle adjustment rod 162 and the swing angle adjustment button 161.
[0033] The swing angle adjustment knob 161 can rotate in the direction around the first hinge axis D1, that is, the swing angle adjustment knob 161 can rotate with the first hinge axis D1 as the rotation axis. The swing angle adjustment rod 162 cooperates with the swing slot 141, that is, the swing angle adjustment rod 162 can be installed in the swing slot 141 accordingly, and can rotate in the swing slot 141 with the first hinge axis D1 as the rotation axis. When the swing angle adjustment knob 161 is rotated, it rotates around the first hinge axis D1, thereby driving the swing angle connecting member 163 to rotate. Through the rotation of the swing angle connecting member 163, the swing angle adjustment rod 162 is driven to rotate around the swing angle adjustment knob 161. Furthermore, through the cooperation between the swing angle adjustment rod 162 and the swing slot 141, the rotation of the swing angle adjustment knob 161 drives the movement of the hinge part 14 through the swing slot 141, so that the hinge part 14 rotates around the first hinge axis D1, and drives the osteotomy guide plate 112 hinged thereto through the hinge part 14 to adjust the swing angle of the osteotomy guide plate 112.
[0034] Furthermore, the swing angle adjustment button 161, the swing angle adjustment rod 162 and the swing angle connecting member 163 can be integrally formed into the swing angle adjustment portion 16, but are not limited thereto. At least one of the swing angle adjustment button 161, the swing angle adjustment rod 162 and the swing angle connecting member 163 can also be formed as a separate part and then assembled with other structures to form the swing angle adjustment portion 16.
[0035] The inclination adjustment part 15 is installed on the hinge part 14. The inclination adjustment part 15 can move relative to the hinge part 14 in a direction perpendicular to the second hinge axis D2. The inclination adjustment part 15 is provided with an inclination groove 151. The osteotomy guide plate part 11 includes an osteotomy guide plate 112, an inclination adjustment rod 113 and an inclination connection member 114, the inclination adjustment rod 113 is parallel to the second hinge axis D2, and the inclination connection member 114 connects the inclination adjustment rod 113 and the osteotomy guide plate 112. The osteotomy guide plate 112 is provided with an osteotomy groove 111. The inclination adjustment rod 113 and the inclination groove 151 are correspondingly matched.
[0036] It should be noted that when the first hinge axis D1 is completely consistent with the first direction Y, and the second hinge axis D2 is completely consistent with the second direction X, the first hinge axis D1 is perpendicular to the second hinge axis D2. At this time, the inclination adjustment part 15 moves in a direction perpendicular to the second hinge axis D2, that is, it can move in the direction of the first hinge axis D1. However, when the first hinge axis D1 is not perpendicular to the second hinge axis D2, at this time, the inclination adjustment part 15 moves in a direction perpendicular to the second hinge axis D2, not in the direction of the first hinge axis D1.
[0037] When the inclination adjustment portion 15 moves in a direction perpendicular to the second hinge axis D2, the inclination groove 151 provided thereon also moves therewith. Thus, the inclination adjustment portion 15 drives the inclination adjustment rod 113 to move through the matching relationship between the inclination groove 151 and the inclination adjustment rod 113. After the inclination adjustment rod 113 moves, it drives the osteotomy guide plate 112 through the inclination connector 114, and makes the osteotomy guide plate 112 rotate around the second hinge axis D2, so as to adjust the inclination of the osteotomy guide plate 112.
[0038] In the aforementioned embodiment, the hinged portion 14 is hingedly connected to the osteotomy guide plate portion 11, which can be referred to Figure 2 and Figure 3 The two side views of the osteotomy guide 10 are shown, wherein: Figure 3 The left side view of the osteotomy guide 10 is shown. The hinge portion 14 may be provided with a hinge hole that penetrates the hinge portion 14 along the second direction X, and the osteotomy guide plate portion 11 may include an opening portion 115 that extends along the third direction Z. Two opening portions 115 may be provided, and they may be located on both sides of the osteotomy guide plate 112 along the second direction X. The space between the two opening portions 115 is used to adapt to the portion of the hinge portion 14 provided with the hinge hole. The opening portions 115 are all provided with hinge holes that are located on the same axis along the second direction X. When the portion of the hinge portion 14 provided with the hinge hole is inserted between the opening portions 115, the hinge hole provided on the opening portion 115 and the hinge hole provided on the hinge portion 14 are located on the same axis. The hinge portion 14 and the osteotomy guide plate portion 11 are then hinged by providing a hinge 20 in the hinge hole.
[0039] Furthermore, on the basis of the opening portion 115 being provided on the osteotomy guide plate 112 , the inclination connecting member 114 may also extend from the opening portion 115 and connect the opening portion 115 and the inclination adjusting rod 113 .
[0040] The hinged portion 14 is hinged to the telescopic portion 12 and can be as follows: Figure 1 and Figure 2 As shown, and refer to Figure 4 The structural schematic diagram of the hinged portion 14 and the telescopic portion 12 is shown, the hinged portion 14 is provided with a through hole penetrating the hinged portion 14 along the first direction Y, and the second telescopic portion 122 is correspondingly provided with a through hole penetrating the hinged portion 14 along the first direction Y. The hinged connection of the hinged portion 14 and the telescopic portion 12 is achieved by matching the through holes correspondingly and arranging the hinge 20 in the through holes.
[0041] Through the above-mentioned settings, the inclination of the osteotomy guide plate 112 can be adjusted through the inclination adjustment part 15, the swing angle of the osteotomy guide plate 112 can be adjusted through the swing angle adjustment part 16, and the telescopic extension of the osteotomy guide plate 112 can be adjusted through the fixing part 13 and the first telescopic part 121. Among them, the inclination adjustment part 15 moves in a direction perpendicular to the second hinge axis D2 to ultimately drive the change of the inclination of the osteotomy guide plate 112, and the way in which the inclination adjustment part 15 moves in a direction perpendicular to the second hinge axis D2 can effectively increase its adjustment range through the longer movement distance of the inclination adjustment part 15 in this direction. The swing angle adjustment part 16 effectively lengthens the distance between the swing angle adjustment button 161 and the swing angle adjustment rod 162 through the swing angle connector 163, effectively increasing the adjustment range of the swing angle adjustment part 16.
[0042] Furthermore, since the inclination adjustment portion 15 is installed on the hinge portion 14 and is directly associated with the osteotomy guide plate portion 11 and the hinge portion 14 which are hinged to each other, the swing angle adjustment portion 16 is installed on the second telescopic portion 122 and is directly associated with the telescopic portion 12 and the hinge portion 14 which are hinged to each other, and the first telescopic portion 121 is installed on the fixed portion 13, it is possible to effectively avoid mutual interference between the various adjustment structures, and it is also possible to avoid affecting the adjustment range of other structures when adjusting the adjustment range of some adjustment structures. Furthermore, it is possible to more quickly adjust through the various adjustment structures according to actual needs, or to more quickly adjust the adjustment range of some or all of the adjustment structures.
[0043] Therefore, according to the aforementioned embodiment, the osteotomy guide 10 can simultaneously achieve an increase in the adjustment range of the inclination angle, swing angle and telescopic amount of the osteotomy guide plate 112, and can more quickly adjust through various adjustment structures according to actual needs, or more quickly adjust the adjustment range of part or all of the adjustment structures.
[0044] In some embodiments, Figure 5 It is shown that Figure 1Section view along section line AA. Figure 5 As shown in the figure, and referring to the contents shown in other figures, the inclination adjustment part 15 includes an inclination adjustment button 152 and a threaded part 153 that are fixedly connected. The inclination adjustment button 152 is used to drive other structures of the inclination adjustment part 15 to adjust the inclination of the osteotomy guide 10.
[0045] The hinged portion 14 is provided with an inclination adjustment hole 142 corresponding to the inclination adjustment portion 15. At least a portion of the inner wall of the inclination adjustment hole 142 is provided with threads corresponding to the threaded portion 153 and is used to cooperate with the threaded portion 153.
[0046] Specifically, at least part of the inner wall of the inclination adjustment hole 142 is provided with threads corresponding to the threaded portion 153, and the entire inner wall of the inclination adjustment hole 142 may be provided with threads corresponding to the threaded portion 153, or part of the inner wall of the inclination adjustment hole 142 may be provided with threads corresponding to the threaded portion 153. The threads on the inner wall of the inclination adjustment hole 142 are matched with the threads of the threaded portion 153. Therefore, when the inclination adjustment knob 152 is rotated, it drives the fixedly connected threaded portion 153 to rotate together. When the threaded portion 153 rotates, the inclination adjustment knob 152 is moved in a direction perpendicular to the second hinge axis D2 through the threads correspondingly provided on the inclination adjustment hole 142. When the inclination adjustment knob 152 moves up and down, the inclination adjustment rod 113 and the inclination connection member 114 are driven through the inclination groove 151 to drive the osteotomy guide plate 112 to adjust its inclination.
[0047] The surface of the tilt adjustment button 152 is provided with a plurality of tilt fixing grooves 1521 arranged in an array and extending in the extending direction of the tilt adjustment button 152. The hinge portion 14 is provided with a tilt limiting structure 143, which extends in the extending direction of the tilt adjustment button 152 and is arranged opposite to the tilt fixing groove 1521. A limiting latch 17 is provided in the tilt limiting structure 143, and the limiting latch 17 can move in the direction toward the tilt adjustment button 152. The limiting latch 17 is used to be fixedly matched with the tilt fixing groove 1521 after moving.
[0048] The inclination limiting structure 143 extends along the extension direction of the inclination adjusting knob 152, that is, the inclination limiting structure 143 extends from the hinge portion 14 along the first direction Y. The inclination fixing groove 1521 is arranged opposite to the inclination limiting structure 143, that is, the inclination fixing groove 1521 is in the third direction Z and keeps facing the inclination limiting structure 143.
[0049] In addition, the limit pin 17 can move in the direction toward the inclination adjustment button 152, that is, after the limit pin 17 moves toward the inclination adjustment button 152, it can partially extend out of the inclination limiting structure 143. By matching the part of the limit pin 17 extending out of the inclination limiting structure 143 with the inclination fixing groove 1521, the rotational freedom of the inclination adjustment button 152 is limited, thereby fixing the inclination of the osteotomy guide plate 112.
[0050] According to the aforementioned embodiment, when the inclination adjustment knob 152 is rotated to a specific position, the inclination adjustment knob 152 can be fixed by moving the limit pin 17. Thus, compared with the general solution of using spring clips to increase damping to achieve soft fixation, the inclination angle of the osteotomy guide 112 can be effectively fixed. Furthermore, the shaking of the osteotomy guide 112 during the osteotomy process can be effectively reduced or even avoided, so as to improve the osteotomy accuracy of the osteotomy guide 10.
[0051] In some embodiments, the inclination angle adjusting portion 15 is provided with threads. Figure 5 As shown in the figure, and with reference to the contents shown in other figures, the inclination adjustment part 15 also includes a linkage part 154. The linkage part 154 is provided with an inclination groove 151. The linkage part 154 is fixedly connected to the threaded part 153 and is located on a side of the threaded part 153 away from the inclination adjustment button 152. The inclination groove 151 surrounds the linkage part 154.
[0052] Since the inclination adjustment part 15 can move in a direction perpendicular to the second hinge axis D2 by cooperating the threads of the threaded part 153 with the threads on the inner wall of the inclination adjustment hole 142, the inclination groove 151 surrounds the linkage part 154, so that during the rotation and movement of the inclination adjustment part 15, the part of the inclination adjustment rod 113 located in the inclination groove 151 will not affect the rotation of the inclination adjustment part 15. Therefore, compared with the general solution of using spring clips to increase damping to achieve soft fixation, the inclination angle of the osteotomy guide plate 112 can be effectively fixed, and further, the shaking of the osteotomy guide plate 112 during the osteotomy process can be effectively reduced or even avoided, so as to improve the osteotomy accuracy of the osteotomy guide 10.
[0053] In some embodiments, reference Figure 6 Another cross-sectional view of the tilt angle adjustment portion 15 is shown. Figure 6 As shown, the inclination adjustment portion 15 includes an inclination adjustment button 152, an inclination thread portion 155 and a linkage portion 154. The inclination adjustment button 152 is fixedly connected to the inclination thread portion 155, and is used to drive other structures of the inclination adjustment portion 15 to adjust the inclination of the osteotomy guide 10. The cross-sectional diameter of the inclination thread portion 155 is smaller than the cross-sectional diameter of the linkage portion 154. The linkage portion 154 is provided with an inclination groove 151.
[0054] The linkage part 154 is provided with an angled threaded hole corresponding to the angled threaded part 155, and the inner wall of the angled threaded hole is provided with threads corresponding to the angled threaded part 155. The threads of the angled threaded part 155 and the angled threaded hole cooperate with each other.
[0055] The surface of the tilt adjustment button 152 is provided with a plurality of tilt fixing grooves 1521 arranged in an array and extending in the extending direction of the tilt adjustment button 152. The hinge portion 14 is provided with a tilt limiting structure 143, which extends in the extending direction of the tilt adjustment button 152 and is arranged opposite to the tilt fixing groove 1521. A limiting latch 17 is provided in the tilt limiting structure 143, and the limiting latch 17 can move in the direction toward the tilt adjustment button 152. The limiting latch 17 is used to be fixedly matched with the tilt fixing groove 1521 after moving.
[0056] The inclination threaded portion 155 cooperates with the thread of the inclination threaded hole, and during the rotation of the inclination adjustment knob 152, the rotational freedom of the linkage portion 154 is limited, so that the linkage portion 154 moves in a direction perpendicular to the second hinge axis D2 relative to the inclination threaded portion 155. That is, the linkage portion 154 moves in a direction perpendicular to the second hinge axis D2 on the inclination threaded portion 155 through the action of the thread. At this time, the position of the inclination adjustment knob 152 in the direction perpendicular to the second hinge axis D2 does not change during the rotation process.
[0057] The rotational freedom of the linkage part 154 during the process of rotating the inclination adjustment knob 152 can be limited by providing an inclination groove 151 whose cross section is adapted to the cross section of the inclination adjustment rod 113, as described later. The rotational freedom of the linkage part 154 is limited by the matching relationship between the inclination adjustment rod 113 and the inclination groove 151. However, in other embodiments, the rotational freedom of the linkage part 154 can be limited by the matching relationship between the inclination adjustment rod 113 and the inclination groove 151. For example, the rotational freedom of the linkage part 154 can be limited by making the hinge part 14 wrap the linkage part 154, and the cross section of the hole of the linkage part 154 correspondingly provided in the hinge part 14 is adapted to the linkage part 154, and there is abutting relationship with the linkage part 154 (such as a rectangular cross section and a semicircular cross section, etc.).
[0058] After the inclination adjustment portion 15 moves to a specific position, the inclination limiting structure 143 can be partially extended to achieve the cooperation between the partial limiting pin 17 extending out of the inclination limiting structure 143 and the inclination fixing groove 1521, thereby limiting the movement freedom of the inclination adjustment button 152, thereby achieving the fixation of the inclination angle of the osteotomy guide plate 112.
[0059] According to the above-mentioned embodiment, when the inclination adjustment button 152 moves to a specific position, the inclination adjustment button 152 can be fixed by moving the limit latch 17. In addition, since the position of the inclination adjustment button 152 in the direction perpendicular to the second hinge axis D2 does not change during the rotation process, the activity space required for the overall movement of the inclination adjustment part 15 is also small after the rotation of the inclination adjustment part 15, thereby, the inclination adjustment of the osteotomy guide 10 can be achieved by occupying a small activity space, and compared with the general solution of using a spring sheet to increase damping to achieve soft fixation, the inclination of the osteotomy guide plate 112 can be effectively fixed, and further, the shaking of the osteotomy guide plate 112 during the osteotomy process can be effectively reduced or even avoided, so as to improve the osteotomy accuracy of the osteotomy guide 10.
[0060] In some embodiments, reference Figure 7 Another cross-sectional view of the tilt angle adjustment portion 15 is shown. Figure 7 As shown, the inclination adjustment part 15 includes an inclination adjustment button 152 and a linkage part 154 which are fixedly connected. The inclination adjustment button 152 is used to drive other structures of the inclination adjustment part 15 to adjust the inclination of the osteotomy guide 10. The linkage part 154 is provided with an inclination groove 151.
[0061] The surface of the inclination adjustment button 152 is provided with a plurality of inclination fixing grooves 1521 which surround the inclination adjustment button 152 and are arranged in an array in the extension direction of the inclination adjustment button 152. The hinge portion 14 is provided with an inclination limiting structure 143 which extends in the extension direction of the inclination adjustment button 152 and is arranged opposite to the inclination fixing groove 1521. A limiting latch 17 is provided in the inclination limiting structure 143, and the limiting latch 17 can move in the direction toward the inclination adjustment button 152. The limiting latch 17 is used to be fixedly matched with the inclination fixing groove 1521 after movement.
[0062] The surface of the tilt adjustment button 152 is provided with a plurality of tilt fixing grooves 1521 surrounding the tilt adjustment button 152. Figure 7 The plurality of inclination fixing grooves 1521 shown in the figure all surround the inclination adjusting button 152. And the inclination fixing grooves 1521 surrounding the inclination adjusting button 152 are arranged along the first direction Y on the surface of the inclination adjusting button 152.
[0063] By directly moving the inclination adjustment portion 15 in a direction perpendicular to the second hinge axis D2, after the inclination adjustment portion 15 moves to a specific position, the inclination limiting structure 143 can be partially extended to achieve the cooperation between the partial limiting pin 17 extending from the inclination limiting structure 143 and the inclination fixing groove 1521, thereby limiting the movement freedom of the inclination adjustment button 152, thereby achieving the fixation of the inclination angle of the osteotomy guide plate 112.
[0064] According to the aforementioned embodiment, when the inclination adjustment button 152 moves to a specific position, the inclination adjustment button 152 can be fixed by moving the limit pin 17. Thus, compared with the general solution of using spring clips to increase damping to achieve soft fixation, the inclination of the osteotomy guide 112 can be effectively fixed. Furthermore, the shaking of the osteotomy guide 112 during the osteotomy process can be effectively reduced or even avoided, so as to improve the osteotomy accuracy of the osteotomy guide 10.
[0065] In some embodiments, on the basis of the aforementioned surface of the tilt adjustment button 152 being provided with a plurality of tilt fixing grooves 1521 surrounding the tilt adjustment button 152, as Figure 7 As shown, the inclination adjustment part 15 further includes a linkage part 154. The linkage part 154 is provided with an inclination groove 151. The linkage part 154 is fixedly connected to the threaded part 153 and is located on a side of the threaded part 153 away from the inclination adjustment button 152. The inclination groove 151 extends from the surface of the linkage part 154 into the linkage part 154, and the cross section of the inclination groove 151 is adapted to the cross section of the inclination adjustment rod 113.
[0066] The inclination groove 151 extends from the surface of the linkage part 154 into the linkage part 154, and the cross section of the inclination groove 151 is adapted to the cross section of the inclination adjustment rod 113, so that the portion of the inclination adjustment rod 113 located in the inclination groove 151 can be matched with the inclination groove 151. When the inclination adjustment part 15 moves in a direction perpendicular to the second hinge axis D2, the rotational freedom of the inclination adjustment part 15 can be limited by the cooperation between the inclination adjustment rod 113 and the inclination groove 151, so that the inclination adjustment part 15 set in this way can be prevented from generating unnecessary rotation during the adjustment process, thereby affecting the inclination adjustment of the osteotomy guide 10. Therefore, through the above-mentioned embodiment, compared with the general solution of using spring sheets to increase damping to achieve soft fixation, the fixation of the inclination angle of the osteotomy guide plate 112 can be better achieved, and then, the shaking of the osteotomy guide plate 112 during the osteotomy process can be better reduced or even avoided, so as to improve the osteotomy accuracy of the osteotomy guide 10.
[0067] In some embodiments, Figure 5 and Figure 7 As shown and with reference to the contents shown in other figures, the linkage part 154 of the inclination adjustment part 15 can be located in the hinge part 14. By opening the inclination hole 144 in the part of the hinge part 14 corresponding to the inclination adjustment rod 113 and the inclination groove 151, the inclination adjustment rod 113 is provided to extend into the hinge part 14 through the inclination hole 144, and then extends into the inclination groove 151, so as to achieve the matching of the inclination adjustment rod 113 and the inclination groove 151. In addition, the diameter of the inclination hole 144 is adapted to the range of the inclination adjustment part 15, that is, the diameter of the inclination hole 144 is consistent with the moving distance of the inclination adjustment part 15 in the direction perpendicular to the second hinge axis D2.
[0068] It should be noted that the above is only a relatively feasible relative relationship between the hinge 14, the tilt adjustment rod 113 and the tilt adjustment part 15, but in other embodiments, it is not limited to this, and the part of the linkage part 154 provided with the tilt groove 151 can extend out of the hinge 14. The tilt adjustment rod 113 directly extends from the hinge 14 into the tilt groove 151 to achieve cooperation with the tilt groove 151.
[0069] In some embodiments, based on any of the above-mentioned configuration schemes of the inclination angle adjustment unit 15, as Figure 5 and Figure 7 As shown in the figure, and with reference to the contents shown in other figures, the inclination limiting structure 143 is provided with a limiting latch hole 1431. The limiting latch 17 is located in the limiting latch hole 1431.
[0070] An elastic member 18 is provided between the limit pin 17 and the limit pin hole 1431. The limit pin 17 includes a first pin segment 171 and a second pin segment 172, and the diameter of the first pin segment 171 is larger than the diameter of the second pin segment 172. The elastic member 18 abuts against the first pin segment 171, and the other end abuts against the bottom of the limit pin hole 1431. The first pin segment 171 can extend out of the inclination limiting structure 143 in the direction toward the inclination adjustment knob 152, and cooperate with the inclination fixing groove 1521. The second pin segment 172 extends into the elastic member 18.
[0071] Compared with the general solution of using spring clips to increase damping to achieve soft fixation, this arrangement can effectively fix the inclination angle of the osteotomy guide 112, and further, can effectively reduce or even avoid the shaking of the osteotomy guide 112 during the osteotomy process, so as to improve the osteotomy accuracy of the osteotomy guide 10.
[0072] In some embodiments, Fig. 9 FIG. 1 is a schematic diagram showing the structure of the swing angle limiter 19. Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown in the figure, and with reference to the contents shown in other figures, the osteotomy guide 10 further includes a swing angle limiter 19. The swing angle limiter 19 is mounted on the second telescopic portion 122 and can move along the first hinge axis D1.
[0073] The swing angle connecting member 163 includes a swing angle connecting plate 164 whose edges are at least partially arcuate. At least part of the arcuate edge of the swing angle connecting plate 164 is a gear structure. The swing angle limiting member 19 includes a limiting base 191, a limiting adjustment button 192 and a limiting protrusion 193. The limiting adjustment button 192 is used to drive the swing angle limiting member 19 to move as a whole. The limiting adjustment button 192 and the limiting protrusion 193 are located on the same side of the limiting base 191. The limiting protrusion 193 is used to mesh with the gear structure of the swing angle connecting plate 164 after the swing angle limiting member 19 moves toward the swing angle connecting plate 164.
[0074] The swing angle connecting member 163 is a swing angle connecting plate 164 with at least a portion of its edge being arc-shaped. The swing angle connecting plate 164 may have a portion of its edge being arc-shaped, that is, the swing angle connecting plate 164 may be as follows: Figure 8 A semicircular structure is shown, but in other embodiments it is not limited thereto, and the swing angle connecting plate 164 may also have all edges that are arc-shaped.
[0075] Furthermore, the swing angle limiter 19 includes a limit base 191, a limit adjustment button 192 and a limit protrusion 193. The limit base 191, the limit adjustment button 192 and the limit protrusion 193 may be formed as a whole with the swing angle limiter 19, but is not limited thereto. Any at least two of the aforementioned parts may be formed as a whole and then assembled with other parts to form the swing angle limiter 19. Alternatively, all the parts may be formed separately and then assembled to form the swing angle limiter 19.
[0076] According to the above-mentioned setting, when the swing angle adjustment knob 161 is rotated to the desired position, the swing angle connecting plate 164 connected to the swing angle adjustment knob 161 is also rotated to the fixed position. At this time, the swing angle limiter 19 is moved to make the limiter protrusion 193 mesh with the teeth of the swing angle connecting plate 164 to achieve the fixation of the position of the swing angle adjustment knob 161. Thus, compared with the general solution of using springs to increase damping to achieve soft fixation, the swing angle of the osteotomy guide plate 112 can be effectively fixed, and further, the shaking of the osteotomy guide plate 112 during the osteotomy process can be effectively reduced or even avoided, so as to improve the osteotomy accuracy of the osteotomy guide 10.
[0077] In some embodiments, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig. 9As shown, the limiting base 191 may include a first limiting base portion 1911 and a second limiting base portion 1912, wherein the second limiting base portion 1912 is located on the side of the first limiting base portion 1911 facing away from the limiting adjustment button 192. The cross section of the first limiting base portion 1911 may be a "convex"-shaped structure to limit the rotational freedom of the limiting base 191, and a limiting protrusion 193 is provided at the protruding portion of the "convex" shape. The second limiting base portion 1912 may be a cylinder having a smaller diameter than the larger part of the "convex"-shaped structure, or may be consistent with the cross-sectional shape of the first limiting base portion 1911, but is not limited thereto.
[0078] The second telescopic portion 122 is provided with a swing angle limiting installation hole 1221 with the same cross-sectional shape corresponding to the first limiting base portion 1911 and the second limiting base portion 1912, for installing the swing angle limiting member 19. An elastic member is provided in the swing angle limiting installation hole 1221, for moving the swing angle limiting member 19 toward the swing angle connecting plate 164 and meshing with the teeth on the edge of the swing angle connecting plate 164. In the process of adjusting the swing angle adjusting portion 16, the swing angle limiting member 19 can be pressed to contact the swing angle limiting member 19 to limit the swing angle adjusting portion 16. Alternatively, the swing angle limiter 19 and the swing angle limiter mounting hole 1221 may both be provided with a helical tooth structure, and cooperate with the elastic member provided in the swing angle limiter mounting hole 1221, so that after pressing the swing angle limiter 19 once, the helical teeth on the swing angle limiter 19 mesh with the helical teeth on the swing angle limiter mounting hole 1221, so as to keep releasing the swing angle limiter 19 from limiting the swing angle adjustment part 16. After the swing angle adjustment is completed, the swing angle limiter 19 is pressed again to release the meshing between the helical teeth to release the swing angle limiter 19, so that the swing angle limiter 19 limits the swing angle adjustment part 16.
[0079] In some embodiments, Figure 4 As shown, a swing angle ball hole 1222 is also provided on the second telescopic portion 122. An elastic member and a swing angle ball are provided in the swing angle ball hole 1222. The elastic member applies force to the swing angle ball so that it abuts against the teeth of the swing angle connecting plate 164. Since the engagement between the swing angle ball structure and the teeth is unstable, the engagement between the swing angle ball and the teeth can apply a certain damping while the swing angle adjustment portion 16 can be relatively easy to rotate. Through the unstable engagement between the swing angle ball and the teeth, it is achieved that each time the swing angle is adjusted, the swing angle adjustment plate 164 can relatively easily move the length of an integer multiple of the tooth gap according to its tooth gap, and a certain damping is provided through the engagement between the swing angle ball and the teeth, thereby further increasing the feel and accuracy during adjustment, and facilitating the swing angle adjustment portion 16 to rotate quickly and accurately to achieve a preset swing angle.
[0080] In some embodiments, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the second telescopic portion 122 includes a bifurcated portion 1223 extending along both the second direction X and the third direction Z. A swing angle mounting column 1224 is provided on the bifurcated portion 1223. The swing angle adjustment knob 161 can be installed on the second telescopic portion 122 by being installed on the swing angle mounting column 1224.
[0081] In some embodiments, Figure 1 , Figure 2 and Figure 3 As shown in the figure, and with reference to the contents shown in other figures, the fixing portion 13 includes a telescopic limiting member 131 , a telescopic limiting hole 132 and a fixing portion base 133 .
[0082] The telescopic limit hole 132 is located on the fixed part base 133. The telescopic limit member 131 cooperates with the telescopic limit hole 132. The telescopic limit member 131 includes a fixedly connected telescopic limit button 1311 and a telescopic threaded portion 1312. The telescopic limit hole 132 is provided with threads corresponding to the telescopic threaded portion 1312. The side of the telescopic threaded portion 1312 away from the telescopic limit button 1311 abuts against the first telescopic portion 121 through the telescopic limit hole 132.
[0083] Among them, by rotating the telescopic limit button 1311, the telescopic threaded part 1312 fixedly connected thereto can be driven to rotate together. In the process of the rotation of the telescopic threaded part 1312, the telescopic limit member 131 can be moved toward the first telescopic part 121 or away from the first telescopic part 121 through the threaded structure corresponding to the telescopic limit hole 132. The telescopic limit member 131 moves toward the first telescopic part 121 and abuts against the first telescopic part 121, so that the telescopic limit member 131 can be locked and limited by the friction between the telescopic limit member 131 and the first telescopic part 121.
[0084] With such an arrangement, the telescopic amount of the osteotomy guide 10 can be adjusted by pushing and pulling the first telescopic part 121 to move it relative to the fixed part 13, and at the same time, the telescopic amount of the osteotomy guide 10 can be fixed by the abutment of the telescopic limiter 131. Therefore, compared with the general solution of using spring clips to increase damping to achieve soft fixation, a greater friction effect can be achieved by abutment to effectively achieve the fixation of the swing angle of the osteotomy guide 112, and further, the shaking of the osteotomy guide 112 during the osteotomy process can be effectively reduced or even avoided, so as to improve the osteotomy accuracy of the osteotomy guide 10.
[0085] In some embodiments, based on the above-mentioned embodiments of specifically setting the fixing portion 13, as Figure 2 and Figure 3As shown, the fixing portion 13 is further provided with a friction column 134. The friction column 134 is arranged opposite to the telescopic threaded portion 1312, or is arranged opposite to the connecting rod portion between the telescopic threaded portion 1312 and the telescopic limit button 1311, so that the damping when the telescopic limit member 131 rotates can be increased to achieve fine abutment adjustment between the telescopic limit member 131 and the first telescopic portion 121.
[0086] For example, in the process of pushing the first telescopic part 121, the telescopic limiter 131 can be completely out of contact with the first telescopic part 121 to quickly move a larger range. After the rapid movement, the telescopic limiter 131 can be rotated to make it contact with the first telescopic part 121, but not completely limit the movement of the first telescopic part 121, so that the first telescopic part 121 can achieve fine telescopic adjustment with greater damping. Finally, after the adjustment is in place, the telescopic limiter 131 is rotated to contact the first telescopic part 121, and the first telescopic part 121 is bent and fixed. Therefore, while achieving fine adjustment of the telescopic amount of the osteotomy guide 10, a faster adjustment speed can be achieved.
[0087] In some embodiments, based on the aforementioned specific embodiments of setting the fixing portion 13, as Figure 2 and 4 As shown, at least one side surface of the first telescopic portion 121 is provided with a rack 1211 structure, that is, among the surfaces where the first telescopic portion 121 contacts the fixed portion 13, at least one surface is provided with a rack 1211 structure. A telescopic ball structure (not shown in the figure) is provided in the fixed portion 13 corresponding to the rack 1211. The telescopic ball portion is located in the fixed portion 13, and is abutted against the surface provided with the rack 1211 structure by the elastic force provided by the elastic member. Through the unstable engagement of the telescopic ball with the rack 1211, it is achieved that each time the telescopic adjustment is performed, the first telescopic portion 121 can be moved more easily by the length of the integer multiple of the tooth gap according to the tooth gap of the rack 1211, and a certain damping is provided by the engagement of the telescopic ball with the rack 1211, thereby further increasing the feel and accuracy during adjustment, and facilitating the first telescopic portion 121 to move quickly and accurately to achieve a preset telescopic amount.
[0088] In some embodiments, Figure 1 , Figure 2 and Figure 3 As shown, the osteotomy guide plate portion 11 further includes a tracking mounting platform 116. The tracking mounting platform 116 includes an inclined surface M1 for mounting a tracking device (not shown in the figure). The tracking device is used to determine the position of the osteotomy guide plate 112 after being recognized by the outside world.
[0089] Specifically, the tracking mounting platform 116 may include a platform body 1161 and a mounting body 1162. The platform body 1161 may include a slope M1 structure. The slope M1 structure may be the top of the slope M1 from the edge of the osteotomy guide plate 112 where the osteotomy groove 111 is provided, that is, the distance between the slope M1 and the osteotomy guide plate 112 is the smallest, and in the first direction Y, the distance between the slope M1 and the osteotomy guide plate 112 gradually increases. The mounting body 1162 may be located on the slope M1 structure. By mounting the tracking device on the mounting body 1162, the tracking device may be mounted on the tracking mounting platform 116.
[0090] Furthermore, the tracking device may include a signal emitted by the outside world (e.g., visible light, infrared light, ultraviolet light, and millimeter wave, etc.) to achieve recognition by the outside world. By installing the tracking device on the inclined surface M1 structure, the tracking device forms an angle with the osteotomy guide plate 112, which can effectively avoid the problem that when there is no angle between the tracking device and the osteotomy guide plate 112, the tracking device has a weak reflection effect in a specific direction, for example, in the first direction Y, resulting in a weak tracking effect.
[0091] Therefore, through the above-mentioned embodiments, while specifically realizing the tracking of the position and posture of the osteotomy guide plate 112, the problem of weak tracking effect caused by weak reflection effect of the tracking device in a specific direction can be effectively avoided, thereby realizing stable tracking of the position and posture of the osteotomy guide plate 112.
[0092] The present application also provides an osteotomy device, comprising any one of the aforementioned osteotomy guides 10 .
[0093] The osteotomy device also includes a movable mechanical arm, the end of which can be used to install medical equipment. The mechanical arm is used to drive the medical equipment installed at its end, so as to drive the medical equipment to realize or assist in realizing the osteotomy operation of orthopedic surgery. The fixing portion 13 of the aforementioned osteotomy guide 10 is installed at the end of the mechanical arm of the osteotomy device. The osteotomy device can specifically include an orthopedic surgical robot.
