Description

Technical Field

[0001] The invention relates to the field of osteotomy operation auxiliary equipment, in particular to an osteotomy guide device. Background Art

[0002] In medical treatment, some cases often require osteotomy. Take Developmental Dysplasia of the Hip (DDH) as an example. DDH is one of the common diseases that require osteotomy. Its symptoms are that the femoral head loses its normal relationship with the acetabulum in the joint capsule, resulting in abnormal development before and after birth.

[0003] At present, the surgical treatment of DDH usually adopts the posterior approach to perform femoral rotation and shortening osteotomy on the patient. Specifically, during the operation, a bone segment is usually cut from the femur first, and then the two femoral segments after osteotomy are connected, and finally the cut bone segment is divided into two arc-shaped bone pieces along the axial direction, and the two arc-shaped bone pieces are wrapped at the interface of the femoral connection, and then the bone pieces are sutured to make them firmly wrapped at the connected femur.

[0004] The current osteotomy guide tool is prone to shaking when clamped on the bone, making the osteotomy surface uneven. As a result, when the two femur sections are docked, the two osteotomy surfaces are difficult to fit tightly, making it difficult for the two femur sections to fuse together, affecting the patient's postoperative healing efficiency.

[0030] like Figure 1 and Figure 2 As shown, the osteotomy guide device of the first embodiment includes: a measuring rod 10 , a first clamping structure 20 and a second clamping structure 30 . Among them, the measuring rod 10 has a first measuring scale 11 arranged along the axial direction of the measuring rod 10; the first clamping structure 20 and the second clamping structure 30 are arranged on the measuring rod 10 at intervals, and the second clamping structure 30 is adjustably arranged on the measuring rod 10; the first clamping structure 20 and the second clamping structure 30 both include: a fixed column 21 arranged along the vertical direction and an upper clamping jaw 22, a lower clamping jaw 23 and a first locking member 24 arranged on the fixed column 21, the upper clamping jaw 22 and the lower clamping jaw 23 are used to clamp bones, the upper clamping jaw 22 is movably arranged on the fixed column 21, the first locking member 24 is used to lock the upper clamping jaw 22 and the lower clamping jaw 23, a first osteotomy groove 221 is arranged on the upper clamping jaw 22, a second osteotomy groove 233 is arranged on the lower clamping jaw 23, and a mounting hole 2241 is also arranged on the upper clamping jaw 22, and the measuring rod 10 is inserted into the mounting hole 2241 of the first clamping structure 20 and the mounting hole 2241 of the second clamping structure 30.

[0031] Applying the technical solution of this embodiment, the osteotomy guide device includes a measuring rod 10, a first clamping structure 20 and a second clamping structure 30. The first clamping structure 20 and the second clamping structure 30 are arranged on the measuring rod 10 at intervals. The measuring rod 10 has a first measuring scale 11 arranged along the axial direction of the measuring rod 10. The doctor can know the distance between the first clamping structure 20 and the second clamping structure 30 through the first measuring scale 11, thereby achieving precise adjustment of the osteotomy length. The first clamping structure 20 and the second clamping structure 30 both include: a fixing column 21 arranged in the vertical direction, an upper clamping jaw 22 and a lower clamping jaw 23. The upper clamping jaw 22 and the lower clamping jaw 23 clamp the human skeleton together and can be locked by the first locking member 24, thereby achieving stable clamping of the human skeleton. At the same time, the upper jaw 22 is provided with a first osteotomy groove 221, and the lower jaw 23 is provided with a second osteotomy groove 233. During osteotomy, the doctor performs osteotomy on the human bone along the extension direction of the first osteotomy groove 221 and the second osteotomy groove 233. Specifically, the doctor intercepts the human bone through the first osteotomy groove 221 of the first clamping structure 20 and the second osteotomy groove 233 of the first clamping structure 20 and forms a first osteotomy surface. Correspondingly, the human bone is intercepted through the first osteotomy groove 221 of the second clamping structure 30 and the second osteotomy groove 233 of the second clamping structure 30 and forms a second osteotomy surface, and the first osteotomy surface and the second osteotomy surface are connected to complete the osteotomy operation. The above structure adopts the method of directly setting the osteotomy groove on the clamping structure, which can ensure that the first clamping structure 20 and the second clamping structure 30 can maintain stable clamping during osteotomy, thereby improving the flatness of the first osteotomy surface and the second osteotomy surface. On the other hand, the first osteotomy groove 221 and the second osteotomy groove 233 are respectively arranged on the upper clamping jaw 22 and the lower clamping jaw 23, which can also ensure the contact area between the upper clamping jaw 22 and the lower clamping jaw 23 and the human skeleton, thereby further improving the clamping stability of the first clamping structure 20 and the second clamping structure 30, and further improving the flatness of the first osteotomy surface and the second osteotomy surface. Therefore, the technical solution of this embodiment effectively solves the problem of poor clamping stability of the osteotomy guide tool in the related art, resulting in uneven osteotomy surface.

[0032] like Figure 1 and Figure 2As shown, in the first embodiment, the lower clamping jaw 23 is fixedly arranged on the fixed column 21, and the upper clamping jaw 22 is provided with a through hole 223, the through hole 223 and the mounting hole 2241 are isolated from each other, and the axis of the through hole 223 and the axis of the mounting hole 2241 are arranged to intersect, the upper clamping jaw 22 is sleeved on the fixed column 21 through the through hole 223, the fixed column 21 is provided with a first external thread, the first locking member 24 is sleeved on the fixed column 21 and is located above the upper clamping jaw 22, and the first locking member 24 is provided with a first internal thread hole arranged in cooperation with the first external thread. In the above structure, the through hole 223 is used to penetrate the fixed column 21, and the mounting hole 2241 is used to penetrate the measuring rod 10. The above setting method has a simple structure and an optimized layout. On the one hand, the distance between the first clamping structure 20 and the second clamping structure 30 can be clearly seen through the measuring rod 10, and on the other hand, the longitudinal adjustment of the upper clamping jaw 22 can be realized, which is convenient for clamping the human skeleton.

[0033] It should be noted that the above-mentioned "intersecting" arrangement means that the axis of the through hole 223 and the axis of the mounting hole 2241 have an angle in space, and are not arranged in parallel. In this embodiment, the axis of the through hole 223 and the axis of the mounting hole 2241 are arranged vertically in space.

[0034] like Figure 1 and Figure 2 As shown, in the first embodiment, the lower clamping jaw 23 includes a lower fixing plate 231 fixedly connected to the fixing column 21 and a lower clamping plate 232 connected to the lower fixing plate 231, the lower clamping plate 232 is provided with a lower clamping groove for contacting and cooperating with the bone, and the second osteotomy groove 233 extends along the length direction of the lower clamping plate 232. In the above structure, the lower fixing plate 231 is used to be connected to the fixing column 21, and the lower clamping plate 232 is used to be provided with a lower clamping groove, so as to facilitate clamping of the human bone.

[0035] It should be noted that, in order to improve the fit between the lower splint 232 and the human skeleton, the end of the lower splint 232 away from the lower fixing portion is an arc-shaped plate, and accordingly, the lower clamping groove is also an arc-shaped groove.

[0036] like Figure 1 and Figure 2As shown, in the first embodiment, the upper clamping jaw 22 includes a mounting block 224 and an upper clamping plate 225 connected to the mounting block 224, a mounting hole 2241 is arranged on the side wall of the mounting block 224 and extends along the width direction of the upper clamping jaw 22, a through hole 223 is arranged on the top wall of the mounting hole 2241 and extends along the thickness direction of the upper clamping jaw 22, and an upper clamping groove 2251 for contacting and cooperating with the bone is arranged on the upper clamping plate 225. In the above structure, the mounting block 224 is used to realize the installation of the upper clamping jaw 22 and the measuring rod 10 and to realize the movement of the upper clamping jaw 22 in the vertical direction, which is specifically embodied in that the through hole 223 and the mounting hole 2241 are arranged on the mounting block 224. This arrangement makes the structure of the upper clamping jaw 22 simple and compact.

[0037] like Figure 1 and Figure 2 As shown, in the first embodiment, the side wall of the measuring rod 10 is also provided with a reference line 12 extending along the axial direction of the measuring rod 10, and the upper surface of the upper clamping jaw 22 of the second clamping structure 30 is also provided with a second measuring scale 2242 extending along the length direction of the upper clamping jaw 22, and the second measuring scale 2242 is matched with the reference line 12 for measurement. In the above structure, the patient may have femoral internal rotation (possibly due to the bone deformation caused by the "inward-facing" feet when the patient walks) or external rotation (possibly due to the bone deformation caused by the "outward-facing" feet when the patient walks) before the operation. In order to solve the problem of internal rotation or external rotation of the patient's bones, the osteotomy guide device of this embodiment also has the function of being able to adjust the bone rotation direction during osteotomy. Specifically, the doctor installs the first clamping structure 20 and the second clamping structure 30 on the bone, adjusts the distance between the first clamping structure 20 and the second clamping structure 30, and performs osteotomy on the human bone through the first osteotomy groove 221 and the second osteotomy groove 233 on the first clamping structure 20 and forms a first osteotomy surface. The doctor then adjusts the position of the second clamping structure 30 by rotating the second clamping structure 30 according to the patient's internal rotation or external rotation angle. The rotation angle can be indicated by the second measuring scale 2242 in coordination with the reference line 12. After adjusting the angle of the second clamping structure 30, the doctor performs osteotomy again to form a second osteotomy surface. In this way, when the first osteotomy surface and the second osteotomy surface are in close contact, the rotation direction of the human bone can be corrected.

[0038] It should be noted that if the patient's bone rotation needs to be corrected during the osteotomy process, at least one of the first osteotomy groove and the second osteotomy groove should be a broken line groove. This can form a plug-in structure when the two bone segments are docked, thereby reducing the probability of rotation between the two bone segments and helping to improve the correction effect of internal rotation or external rotation.

[0039] Specifically, if Figure 1 and Figure 2As shown, in the first embodiment, the measuring rod 10 is also provided with a reference line 12 extending in the axial direction of the measuring rod 10, and an inclined transition section is provided between the mounting block 224 and the upper clamping plate 225 of the upper clamping jaw 22 of the second clamping structure 30, so that the upper clamping plate 225 and the mounting block 224 are arranged at intervals in the vertical direction, and the upper surface of the mounting block 224 includes an arcuate surface, which is concentrically arranged with the side wall of the measuring rod 10, and the arcuate surface is also provided with a second measuring scale 2242 extending in the length direction of the upper clamping jaw 22, and the second measuring scale 2242 is matched with the measurement of the reference line 12. The above structure allows the doctor to adjust the position of the second clamping structure 30 by rotating the second clamping structure 30 according to the angle of internal rotation or external rotation of the patient, and the concentric arrangement of the arcuate surface with the side wall of the measuring rod 10 can improve the accuracy of adjusting the rotation angle of the second clamping structure 30, thereby helping to improve the correction effect of internal rotation or external rotation.

[0040] like Figure 1 and Figure 2 As shown, in the first embodiment, the projections of the first osteotomy groove 221 and the second osteotomy groove 233 on the horizontal plane are completely overlapped, and the first osteotomy groove 221 and the second osteotomy groove 233 are both straight line grooves or broken line grooves. In the above structure, the first osteotomy groove 221 and the second osteotomy groove 233 have the same structure, so that the doctor can insert the wire saw into the first osteotomy groove 221 and the second osteotomy groove 233 at the same time to perform osteotomy operations, thereby ensuring osteotomy efficiency.

[0041] Specifically, if Figure 1 and Figure 2 As shown, in the first embodiment, the first osteotomy groove 221 and the second osteotomy groove 233 are both broken line grooves, and the second osteotomy groove 233 includes a first straight groove segment 2211, a first connecting groove segment 2212 and a second straight groove segment 2213 which are sequentially arranged in the direction from close to the measuring rod 10 to far away from the measuring rod 10, and the first straight groove segment 2211 and the second straight groove segment 2213 are parallel and spaced apart in the width direction of the upper clamping jaw 22. On the one hand, the above structure can ensure the osteotomy efficiency of the doctor, and at the same time, the first osteotomy groove 221 and the second osteotomy groove 233 are both broken line grooves, so that the osteotomy guide device of this embodiment can have the function of correcting the patient's internal rotation or external rotation, thereby improving the functionality of the osteotomy guide device.

[0042] like Figure 1 and Figure 2As shown, in the first embodiment, the osteotomy guide device further includes an elastic member 40 and a second locking member 50. The elastic member 40 is sleeved on the measuring rod 10 and is located between the first clamping structure 20 and the second clamping structure 30. The elastic member 40 can push the second clamping structure 30 in a direction away from the first clamping structure 20 under the action of the elastic reset force; the second locking member 50 is adjustably arranged on the measuring rod 10 and is located on the side of the second clamping structure 30 away from the elastic member 40, and the second locking member 50 is in abutment with the second clamping structure 30. In the above structure, the elastic member 40 is sleeved on the measuring rod 10 and is located between the first clamping structure 20 and the second clamping structure 30, and can push the second clamping structure 30 in a direction away from the first clamping structure 20. The doctor can adjust the distance between the first clamping structure 20 and the second clamping structure 30 according to the length of the bone segment to be cut. Specifically, the elastic member 40 can stack the second clamping structure 30 to the end of the measuring rod 10 when no external force is applied, and the doctor needs to adjust the second locking member 50 to move the second clamping structure 30 toward the first clamping structure 20 to adjust the distance between the first clamping structure 20 and the second clamping structure 30 to a suitable position. On the one hand, the above structure enables the first clamping structure 20 and the second clamping structure 30 to be stably maintained at a suitable position. On the other hand, after the first osteotomy plane is formed, the first clamping structure 20 and the second clamping structure 30 can be maintained at a predetermined position under the action of the elastic reset force of the elastic member 40, thereby not affecting the formation of the second osteotomy plane.

[0043] Preferably, the elastic member 40 is a wave spring.

[0044] like Figure 1 and Figure 2 As shown, in the first embodiment, the side wall of the measuring rod 10 includes a plane structure and an arc surface structure connected to the plane structure, the first measuring scale 11 is arranged on the plane structure, the arc surface structure is provided with a second external thread, the first clamping structure 20 is fixedly arranged on the measuring rod 10, the second locking member 50 is sleeved on the measuring rod 10, and the second locking member 50 is provided with a second internal thread hole arranged in cooperation with the second external thread. In the above structure, the side wall of the measuring rod 10 includes a plane structure and an arc surface structure connected to the plane structure so that the first clamping structure 20 and the second clamping structure 30 will not rotate on the measuring rod 10, so that the first clamping structure 20 and the second clamping structure 30 can be stably located in the clamping position. In addition, the measuring rod 10 is a threaded rod, and the second locking member 50 has a threaded hole. This matching mode enables the second locking member 50 to be stably and accurately adjusted on the measuring rod 10, which is conducive to improving the clamping stability of the first clamping structure 20 and the second clamping structure 30.

[0045] It should be noted that, in the first embodiment, the first clamping structure 20 is fixedly arranged with the measuring rod 10 .

[0046] like Figure 1 and Figure 2 As shown, in the first embodiment, the second locking member 50 includes a locking sleeve 51 and a handle 52 disposed on the outer side wall of the locking sleeve 51, the second internal threaded hole is disposed on the locking sleeve 51, and a notch 53 extending along the axial direction of the locking sleeve 51 is formed at one end of the locking sleeve 51 facing the second clamping structure 30, and the notch 53 is connected to the second internal threaded hole. In the above structure, the doctor can observe the first measuring scale 11 through the notch 53, thereby helping the doctor to know the accurate distance between the first clamping structure 20 and the second clamping structure 30.

[0047] Preferably, one end of the locking sleeve 51 facing the second clamping structure 30 is contracted toward the axis of the locking sleeve 51 , so that the locking sleeve 51 does not affect the measurement coordination between the second measuring scale 2242 and the reference line 12 .

[0048] Specifically, there are multiple notches 53 , and in the first embodiment, there are four notches 53 . Preferably, the angle between each notch 53 is 90°, and the intersection of the extension lines of the two sides of each notch 53 along the axis of the locking sleeve 51 is on the axis of the locking sleeve 51 .

[0049] like Figure 1 and Figure 2 As shown, in embodiment 1, the osteotomy guide device also includes a rotating rod 60, and a mounting hole for mounting the rotating rod 60 is provided on the first locking member 24. The rotating rod extends along the radial direction of the first locking member 24. The doctor can adjust the tightness of the first locking member 24 to the upper clamp 22 and the lower clamp 23 by rotating the rotating rod 60.

[0050] like Figure 3 and Figure 4 As shown, the present application also includes a second embodiment of the osteotomy guide device. The difference between the osteotomy guide device of the second embodiment and the osteotomy guide device of the first embodiment is that the structures of the first osteotomy groove 221 and the second osteotomy groove 233 are different. Specifically, in the second embodiment, the projections of the first osteotomy groove 221 and the second osteotomy groove 233 on the horizontal plane are partially overlapped. The above structure can further enhance the therapeutic effect of the osteotomy operation. Specifically, the doctor can select an appropriate osteotomy method according to the actual situation of the patient, thereby enhancing the therapeutic effect of the osteotomy operation.

[0051] Specifically, if Figure 3 and Figure 4As shown, in the second embodiment, the first osteotomy groove 221 includes a third straight groove segment 2217, a folded groove segment 2218 and a fourth straight groove segment 2219 arranged in sequence in the direction from close to the measuring rod 10 to far away from the measuring rod 10, and the folded groove segment 2218 includes a first folded groove segment connected to the third straight groove segment 2217 and a second folded groove segment connected to the fourth straight groove segment and arranged at an angle to the first folded groove segment; the second osteotomy groove 233 includes a fifth straight groove segment 2331 arranged opposite to the third straight groove segment 2217, a sixth straight groove segment 2332 arranged opposite to the fourth straight groove segment 2219 and a second connecting groove segment 2333 arranged offset from the folded groove segment 2218. The above structure is simple and easy to process, and enables the osteotomy guide device of this embodiment to have the function of correcting the patient's internal rotation or external rotation, thereby improving the functionality of the osteotomy guide device.

[0052] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0053] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0054] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
