Description

Technical Field

[0001] This invention relates to the field of artificial joint repair tools, specifically to a fully adjustable osteotomy device. Background Technology

[0002] In total knee replacement surgery, the position and angle of the osteotomy surface are generally adjusted by intramedullary positioning. The perfection of the surgery depends on the surgeon's experience and requires a high level of skill.

[0003] The application of navigation tools enables external measurement of force lines, individualized force line control, precise preoperative dual-plane planning, and easier achievement of ligament balance.

[0004] This invention aims to better realize the preoperative and intraoperative planning functions of navigation. Unlike traditional surgery, the planning process does not have a standard reference point at the beginning, and each patient's actual situation is different, so the navigation tool needs to be different. Therefore, the adjustability of the tool is required to be high.

[0005] Currently, all osteotomy tools used in total knee replacement are fixed osteotomy methods. Taking distal femoral osteotomy as an example, it requires the combined use of an intramedullary locator and a distal osteotomy plate. The intramedullary locator adjusts the varus / valgus angle of the femur, while the distal osteotomy plate adjusts the amount of bone removed. Traditional osteotomy instruments can only adjust the varus / valgus angle and the amount of bone removed, but cannot adjust the anteversion / anteroversion angle. Since navigation-guided osteotomy methods measure the force line direction externally, they require adjustment of the anteversion / anteroversion angle of the femur. Therefore, traditional instruments cannot meet the adjustment requirements of navigation-guided osteotomy.

[0006] In clinical surgery, the need for navigation tools varies depending on the individual patient's condition. However, total knee arthroplasty requires a high degree of adjustability for these tools, and current osteotomy tools still present the problem of inflexible adjustment of the amount of bone removed. Therefore, a more reasonable technical solution is needed to adapt to different osteotomy requirements. Summary of the Invention

[0007] The purpose of this invention is to provide a fully adjustable osteotomy tool to solve the problem that the amount of osteotomy that can be flexibly adjusted when performing osteotomy with existing osteotomy tools.

[0008] To achieve the above objectives, the present invention provides an omnidirectional fine-tuning osteotomy device, comprising:

[0009] Base;

[0010] A bone volume adjustment mechanism is connected to the base. The telescopic end of the bone volume adjustment mechanism can move along the Z direction to adjust the length of the osteotomy. The telescopic end of the bone volume adjustment mechanism is provided with a fixed seat.

[0011] A flexion adjustment mechanism, the movable end of which can move along the Z direction, is connected to the fixation base so that when the bone mass adjustment mechanism is activated, the distance between the fixation base and the base can be adjusted.

[0012] A tilt adjustment mechanism, the adjustment end of which is movable along the Z-axis, is connected to the fixed base; and

[0013] The osteotomy mechanism is connected at one end to the adjustment end of the tilt adjustment mechanism and at the other end to the movable end of the flexion adjustment mechanism. The fixed base is movably connected to the osteotomy mechanism via the first column.

[0014] Wherein, the line connecting the adjusting end and the first column is perpendicular to the line connecting the movable end and the first column. When the bending adjustment mechanism is activated, the osteotomy mechanism can rotate around the X-axis; when the tilt adjustment mechanism is activated, the osteotomy mechanism can rotate around the Y-axis.

[0015] In one possible design, the bone mass adjustment mechanism includes a first rotating column, a first rack, and a first gear that meshes with the first rack; the length direction of the first rack is parallel to the Z-direction.

[0016] The first rotating column is rotatably connected to the base, and the first gear is fixedly connected to the first rotating column by a key connection and meshes with the first rack so that when the first rotating column is turned, the first rack can be driven to move along the Y direction.

[0017] In one possible design, the end of the first rotating column is provided with a first screw cap, and the first screw cap is provided with at least two arc-shaped grooves.

[0018] In one possible design, the bone mass adjustment mechanism further includes a mounting base detachably connected to the base by fasteners; the mounting base is disposed between the first screw cap and the base; the first rotating column passes through the mounting base and the base in sequence and is connected to the first gear.

[0019] In one possible design, the base is provided with a stop groove, and the first rack is provided with a stop platform adapted to the stop groove, so that when the stop platform is engaged in the stop groove, the position of the first rack can be limited.

[0020] In one possible design, the flexion adjustment mechanism includes a second column, a second rack, and a second gear that engages with the second rack; the length direction of the second rack is parallel to the Z-direction, and the second rack is connected to the osteotomy mechanism;

[0021] The second rotating column is rotatably connected to the fixed base, and the second gear is fixedly connected to the second rotating column by a key connection and meshes with the second rack, so that when the second rotating column is turned, the second rack can be driven to move along the Y direction, thereby driving the osteotomy mechanism to rotate around the X axis.

[0022] In one possible design, the top of the second rack is provided with a first ball head, and the bottom surface of the osteotomy mechanism is provided with a first ball socket that is adapted to the first ball head. The first ball head is engaged in the first ball socket so that when the second rack moves, it can drive the osteotomy mechanism to move.

[0023] In one possible design, a neck column is provided between the first ball head and the second rack, the flexion adjustment mechanism further includes a limiting platform, the bottom surface of the osteotomy mechanism is provided with a limiting groove adapted to the limiting platform, the neck column passes through the limiting platform, and the limiting platform is locked in the limiting groove.

[0024] In one possible design, the tilt adjustment mechanism includes a turntable, a third rotating column, a base, and a second column. The second column is connected to the osteotomy mechanism, the base is disposed at the bottom of the second column, and the third rotating column is rotatably connected to the fixed seat and eccentrically connected to the turntable so that when the third rotating column is turned, it can drive the turntable to push the base.

[0025] In one possible design, the osteotomy mechanism includes an osteotomy plate and an adjustment plate snapped onto the osteotomy plate; one end of the adjustment plate is rotatably connected to the adjustment end of the tilt adjustment mechanism, the other end is rotatably connected to the movable end of the flexion adjustment mechanism, and the third end is rotatably connected to the first column.

[0026] This method allows for adjustment not only of the bone resection length but also of the resection angle (including inversion / exversion and flexion angles). This enables the resection of bone of different shapes and lengths based on the patient's bone condition, helping surgeons to perform osteotomies from various angles and dimensions to maximize practical needs, restore the patient's normal posture, and bring benefits to the patient. This expands the applicability of this omnidirectional micro-adjustable osteotomer, making it better suited to different osteotomy requirements.

Detailed Implementation

[0033] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] According to a specific embodiment of the present invention, an all-around fine-tuning osteotomy device is provided. This all-around fine-tuning osteotomy device can be used in conjunction with a knee joint navigation system to complete precise knee joint surgery, thereby improving the accuracy of the surgery and the patient's satisfaction rate.

[0035] See Figure 1 and Figure 2 As shown, the omnidirectional fine-tuning osteotomy device includes: a base 11; a bone volume adjustment mechanism 2 connected to the base 11, the telescopic end of the bone volume adjustment mechanism 2 being movable along the Z-direction to adjust the length of the osteotomy, the telescopic end of the bone volume adjustment mechanism 2 being provided with a fixed seat 7; a flexion adjustment mechanism 3, the movable end of which is movable along the Z-direction, the flexion adjustment mechanism 3 being connected to the fixed seat 7 so that when the bone volume adjustment mechanism 2 is activated, the distance between the fixed seat 7 and the base 11 can be adjusted; an tilt adjustment mechanism 4, the adjustment end of which is movable along the Z-direction, the tilt adjustment mechanism 4 being connected to the fixed seat 7; and an osteotomy mechanism 5, one end of which is connected to the adjustment end of the tilt adjustment mechanism 4, and the other end of which is connected to the movable end of the flexion adjustment mechanism 3, the fixed seat 7 being movably connected to the osteotomy mechanism 5 via a first column 6.

[0036] The line connecting the adjusting end and the first column 6 is perpendicular to the line connecting the movable end and the first column 6. When the bending adjustment mechanism 3 is activated, the osteotomy mechanism 5 can rotate around the X-axis; when the tilt adjustment mechanism 4 is activated, the osteotomy mechanism 5 can rotate around the Y-axis.

[0037] This method allows for adjustment not only of the bone resection length but also of the resection angle (including inversion / exversion and flexion angles). This enables the resection of bone of different shapes and lengths based on the patient's bone condition, helping surgeons to perform osteotomies from various angles and dimensions to maximize practical needs, restore the patient's normal posture, and bring benefits to the patient. This expands the applicability of this omnidirectional micro-adjustable osteotomer, making it better suited to different osteotomy requirements.

[0038] It should be noted that in this invention, when the movable end of the flexion adjustment mechanism 3 drives the osteotomy mechanism 5 to rotate around the X-axis, the adjustment angle is the flexion angle, and the rotation range is ±8°, that is, the osteotomy mechanism 5 can rotate around the X-axis within a range of 16°; when the adjustment end of the tilt adjustment mechanism 4 drives the osteotomy mechanism 5 to rotate around the Y-axis, the adjustment angle is the inversion / exversion angle, and the rotation range is ±8°, that is, the osteotomy mechanism 5 can rotate around the Y-axis within a range of 16°. The bone volume adjustment mechanism 2 is mainly used to adjust the amount of osteotomy, with an adjustment range of ±8mm, that is, the adjustment range of the amount of osteotomy is 16mm.

[0039] In one embodiment of the present invention, the bone mass adjustment mechanism 2 includes a first rotating column 21, a first rack 22, and a first gear 23 that engages with the first rack 22; the length direction of the first rack 22 is parallel to the Z direction; the first rotating column 21 is rotatably connected to the base 11, and the first gear 23 is fixedly connected to the first rotating column 21 by a key connection and meshes with the first rack 22 so that when the first rotating column 21 is turned, the first rack 22 can be driven to move along the Y direction.

[0040] Specifically, when the first rotating column 21 is turned in the first direction, the first gear 23 rotates, transmitting force to the first rack 22, causing it to move vertically and thus adjusting the position between the base 11 and the fixed seat 7. When the first rotating column 21 is turned in the second direction, the first gear 23 rotates, transmitting force to the first rack 22, causing it to move vertically in the opposite direction. This allows for adjustment of the amount of osteotomy.

[0041] In one embodiment provided by the present invention, see [reference needed]. Figure 1 and Figure 2 As shown, the end of the first rotating column 21 is provided with a first screw cap 24, and the first screw cap 24 is provided with at least two arc-shaped grooves 25, so that the fingertips can fit tightly in the grooves 25, thereby holding the first screw cap 24 to effectively rotate the first rotating column 21, and thus adjust the position of the first rack 22.

[0042] In this invention, the first screw cap 24 is provided with four arc-shaped grooves 25, and the grooves 25 have curved surfaces, so as to make it easy to fit the fingertips.

[0043] In one embodiment of the present invention, the bone mass adjustment mechanism 2 further includes a mounting base 26, which is detachably connected to the base 11 by fasteners; and the mounting base 26 is disposed between the first screw cap 24 and the base 11; the first rotating column 21 passes through the mounting base 26 and the base 11 in sequence and is connected to the first gear 23.

[0044] The design of the mounting base 26 provides a support point for the first screw cap 24, thereby allowing the first rotating column 21 to rotate smoothly. Additionally, it avoids direct wear on the outer surface of the fixed base 7, thus improving the smoothness of rotation.

[0045] It is understood that in this invention, the first rotating column 21 can be connected to the fixed base 7 by a threaded connection, so that the first rotating column can be locked onto the fixed base 7 while rotating, preventing backward movement, thereby enabling the first gear 23 and the first rack 22 to mesh and transmit power stably.

[0046] In one embodiment of the present invention, a stop groove 12 is provided on the base 11, and a stop platform 27 adapted to the stop groove 12 is provided on the first rack 22, so that when the stop platform 27 is engaged in the stop groove 12, the position of the first rack 22 can be limited, thereby preventing the movement range of the first rack 22 from exceeding the limit and affecting the normal use of the osteotomy device.

[0047] In one embodiment of the present invention, the flexion adjustment mechanism 3 includes a second rotating column 31, a second rack 32 and a second gear 33 that cooperates with the second rack 32; the length direction of the second rack 32 is parallel to the Z direction, and the second rack 32 is connected to the osteotomy mechanism 5.

[0048] The second rotating column 31 is rotatably connected to the fixed base 7. The second gear 33 is fixedly connected to the second rotating column 31 by a key connection and meshes with the second rack 32. When the second rotating column 31 is turned, the second rack 32 can be driven to move along the Y direction, thereby driving the osteotomy mechanism 5 to rotate around the X axis.

[0049] Specifically, when the second rotating column 31 is turned in the first direction, the second gear 33 rotates. The second gear 33 then transmits force to the second rack 32, causing it to move vertically. This, in turn, causes the osteotomy mechanism 5 to rotate around the X-axis, resulting in the osteotomy mechanism 5 oscillating. When the second rotating column 31 is turned in the second direction, the second gear 33 rotates. The second gear 33 then transmits force to the second rack 32, causing it to move in the opposite direction vertically. This, in turn, causes the osteotomy mechanism 5 to oscillate in the opposite direction. Thus, the bending angle is adjusted.

[0050] It should be noted that the first direction refers to either clockwise or counterclockwise, and the second direction refers to the opposite direction to the first direction, which is either counterclockwise or clockwise.

[0051] When the second sprocket 31 is turned, whether the second rack 32 moves upward or downward depends on the position of the first rack 22 relative to the second gear 33. For example, when the second rack 32 is located to the right of the second gear 33 (understood by comparison with the direction of the drawing viewed at eye level), turning the second sprocket 31 clockwise will cause the second rack 32 to move downward; while turning the second sprocket 31 counterclockwise will cause the second rack 32 to move upward. Those skilled in the art can configure this according to actual needs; this invention is merely illustrative.

[0052] In one embodiment of the present invention, the top of the second rack 32 is provided with a first ball head 34, and the bottom surface of the osteotomy mechanism 5 is provided with a first ball socket adapted to the first ball head 34. The first ball head 34 is engaged in the first ball socket so that when the second rack 32 moves, it can drive the osteotomy mechanism 5 to move. In this way, the first ball head 34 can drive the osteotomy mechanism 5 to move. The matching method of the first ball head 34 and the first ball socket is beneficial to drive the osteotomy mechanism 5 to move smoothly and adapt well to the height of the second rack 32.

[0053] Furthermore, a cervical column is provided between the first ball head 34 and the second rack 32. The bending adjustment mechanism 3 also includes a limiting platform 35. The bottom surface of the osteotomy mechanism 5 is provided with a limiting groove adapted to the limiting platform 35. The cervical column passes through the limiting platform 35, and the limiting platform 35 is locked in the limiting groove. In this way, the cervical column can be held by the limiting platform 35, so that when the second rack 32 moves, it can drive the osteotomy mechanism 5 to move.

[0054] The purpose of this design is that the first ball head 34 and the first ball socket cooperate, and the limiting platform 35 and the cervical column cooperate, which can form a dual connection relationship. Even if the cooperation of one of them fails, the osteotomy mechanism 5 can still be effectively moved through the cooperation of the other.

[0055] In one embodiment of the present invention, the tilt adjustment mechanism 4 includes a turntable 41, a third rotating column 42, a base 43, and a second column 44. The second column 44 is connected to the osteotomy mechanism 5, and the base 43 is disposed at the bottom of the second column 44. The third rotating column 42 is rotatably connected to the fixed base 7 and eccentrically connected to the turntable 41 so that when the third rotating column 42 is turned, the turntable 41 can be driven to push the base 43.

[0056] Specifically, when the third rotating column 42 is turned, the eccentric setting allows the turntable 41 to push the base 43 up and down, thereby adjusting the position of the second column 44 and indirectly adjusting the sway angle of the osteotomy mechanism 5. This allows for adjustment of the inversion / exversion angle.

[0057] Specifically, the top of the second column 44 is provided with a second ball head, and the bottom surface of the osteotomy mechanism 5 is provided with a second ball socket that matches the second ball head. The second ball head is engaged in the second ball socket so that when the second column 44 moves, it can drive the osteotomy mechanism 5 to move. In this way, the second ball head can drive the osteotomy mechanism 5 to move. The matching method of the second ball head and the second ball socket is beneficial for driving the osteotomy mechanism 5 to move smoothly and adapting well to the height of the second column 44.

[0058] Similar to the structure of the second rack 32, a neck column is also provided between the second ball head and the second column 44. The tilt adjustment mechanism 4 also includes a limiting platform 35. The bottom surface of the osteotomy mechanism 5 is provided with a limiting groove adapted to the limiting platform 35. The neck column passes through the limiting platform 35, and the limiting platform 35 is locked in the limiting groove. In this way, the neck column can be held by the limiting platform 35, so that when the second column 44 moves, it can drive the osteotomy mechanism 5 to move.

[0059] In this invention, the top of the first column 6 is also provided with a third ball head, and the bottom surface of the osteotomy mechanism 5 is provided with a third ball socket that matches the third ball head. The third ball head is engaged in the third ball socket so that when the first column 6 moves, it can drive the osteotomy mechanism 5 to move. In this way, the third ball head can drive the osteotomy mechanism 5 to move. The matching method of the third ball head and the third ball socket is beneficial to driving the osteotomy mechanism 5 to move smoothly and adapting well to the height of the first column 6.

[0060] In this invention, a neck column is also provided between the third ball head and the second column 44. The bottom surface of the osteotomy mechanism 5 is provided with a limiting groove, and a limiting platform 35 is engaged in the limiting groove. The neck column passes through the limiting platform 35, and the limiting platform 35 is engaged in the limiting groove. In this way, the neck column can be held by the limiting platform 35, thereby allowing the first column 6 to move slightly relative to the osteotomy mechanism 5, and thus adapt to the position of the bending adjustment mechanism 3 and the tilt adjustment mechanism 4.

[0061] In one embodiment, the mating structure of the ball head and the ball socket is also adapted to the first rack 22, the second rack 32, and the first post 6.

[0062] In one exemplary embodiment of the present invention, the osteotomy mechanism 5 includes an osteotomy plate 51 and an adjusting plate 52 snapped onto the osteotomy plate 51. One end of the adjusting plate 52 is rotatably connected to the adjusting end of the tilt adjustment mechanism 4, the other end is rotatably connected to the movable end of the flexion adjustment mechanism 3, and the third end is rotatably connected to the first column 6. In this way, when the adjusting plate 52 is lifted upwards or moved downwards, it can drive the osteotomy plate 51 to move synchronously. Furthermore, the way the adjusting plate 52 and the osteotomy plate 51 are coupled facilitates installation and maintenance.

[0063] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
