[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise stated, the directional words such as "upper" and "lower" used generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0037] The embodiments of the present application provide an alignment handle and a knee joint surgery alignment verification tool, which are described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0038] First, the embodiment of the present application provides an alignment handle for knee joint surgery alignment verification, such as Figure 1 and Figure 4As shown, the alignment handle 10 includes a handle body 11, and the handle body 11 includes an alignment portion 111 and a joint portion 112 that are connected to each other. The side of the joint portion 112 that is away from the alignment portion 111 is used to be detachably connected to at least two different types of surgical instruments 30, and the surgical instruments 30 need to be checked during knee joint surgery. Among them, the surgical instrument 30 is provided with an interface 31 for matching and connecting with the joint portion 112, and the interfaces 31 on different types of surgical instruments 30 are the same, so as to achieve the adaptation of different types of surgical instruments 30 to the alignment handle 10. In other words, the alignment handle 10 in the embodiment of the present application can be adapted to different types of surgical instruments 30 in knee joint surgery, so that the types and quantities of instruments required in knee joint surgery can be greatly reduced, thereby improving the efficiency of the operation.

[0039] Among them, at least one first alignment hole 1111 is provided on the alignment part 111, and the first alignment hole 1111 penetrates the alignment part 111 along the first direction X. The first alignment hole 1111 is used for inserting the vertical line rod 20, so as to check the vertical lines of different types of surgical instruments 30 through the vertical line rod 20. That is to say, when checking the vertical line, the surgical instrument 30 is placed at the corresponding position during the knee joint surgery, and the joint part 112 of the alignment handle 10 is matched and connected with the interface 31 on the surgical instrument 30, and the vertical line rod 20 is inserted into the first alignment hole 1111, and then the position of the surgical instrument 30 is adjusted according to the relationship between the axis of the vertical line rod 20 and the vertical line at the corresponding position, so as to ensure that the surgical instrument 30 is adjusted to the target position, so as to facilitate the operation.

[0040] It should be noted that the first direction X in the embodiment of the present application refers to the thickness direction of the alignment handle 10, that is, the direction of the vertical line when the vertical line is checked. In other words, when the vertical line is checked, it is possible to judge whether the corresponding surgical instrument 30 is adjusted to the target position based on whether the axial direction of the vertical line rod 20 inserted into the first alignment hole 1111 is consistent with the vertical line of the corresponding position.

[0041] In the embodiment of the present application, the alignment handle 10 includes a handle body 11, and the handle body 11 includes an alignment portion 111 and a coupling portion 112 that are interconnected. The side of the coupling portion 112 that is away from the alignment portion 111 is used for detachable connection with at least two different types of surgical instruments 30. The alignment portion 111 is provided with at least one first alignment hole 1111, and the first alignment hole 1111 penetrates the alignment portion 111 along a first direction X. The first alignment hole 1111 is used for inserting a vertical alignment rod 20 so as to perform vertical alignment verification on different types of surgical instruments 30 through the vertical alignment rod 20. The present application designs the alignment handle 10 to be detachably connected to different types of surgical instruments 30, and sets the same interface 31 on different types of surgical instruments 30, so that during the knee joint surgery, only one alignment handle 10 can be used to cooperate with the line-setting rod 20 and different types of surgical instruments 30 to achieve the line verification of different positions in the knee joint surgery, thereby reducing the types and number of instruments required in the knee joint surgery, and then effectively simplifying the coordination process between the alignment handle 10 and different types of surgical instruments 30, thereby improving the surgical efficiency.

[0042] Optionally, the alignment handle 10 includes a snap-in connector 12, which is movably connected to the coupling portion 112, and the snap-in connector 12 is used to receive a driving force to move between a locked position and an unlocked position, that is, the alignment handle 10 cooperates with the surgical instrument 30 through the snap-in connector 12 and the coupling portion 112 at the same time to improve the connection stability between the alignment handle 10 and the surgical instrument 30, and at the same time, the movement of the snap-in connector 12 between the locked position and the unlocked position can realize a detachable connection between the alignment handle 10 and the surgical instrument 30.

[0043] When the clamping member 12 is in the locking position, the clamping member 12 is used to be inserted into the interface 31 of the surgical instrument 30 and clamped with the surgical instrument 30 to lock the surgical instrument 30 and the joint 112; when the clamping member 12 is in the unlocking position, the clamping member 12 can be separated from the surgical instrument 30 to release the lock of the surgical instrument 30 and the joint 112. In other words, the alignment handle 10 is mainly connected to the surgical instrument 30 by the clamping and separation of the clamping member 12 and the interface 31 on the surgical instrument 30, and the joint 112 mainly plays a positioning role to improve the stability of the alignment handle 10 when connected to the surgical instrument 30.

[0044] In some embodiments, the joint portion 112 includes a first surface 1121 and a second surface 1122 opposite to each other, and the first surface 1121 and the second surface 1122 extend in a direction from the alignment portion 111 toward the joint portion 112, that is, the first surface 1121 and the second surface 1122 are two opposite surfaces extending in a length direction of the alignment handle 10. The clamping member 12 is located on the first surface 1121 and is movably connected to the joint portion 112. A clamping portion 121 is formed on a side of the clamping member 12 away from the alignment portion 111. When the clamping member 12 moves from the unlocking position to the locking position, the clamping portion 121 moves in a direction from the second surface 1122 toward the first surface 1121, so that the clamping member 12 is clamped with the surgical instrument 30; when the clamping member 12 moves from the locking position to the unlocking position, the clamping portion 121 moves in a direction from the first surface 1121 toward the second surface 1122, so that the clamping member 12 is separated from the surgical instrument 30.

[0045] It should be noted that the spacing between the first surface 1121 and the second surface 1122 can represent the minimum size that the interface 31 on the surgical instrument 30 needs to be compatible with in the direction from the first surface 1121 to the second surface 1122 when the coupling portion 112 is connected to the surgical instrument 30. In the embodiment of the present application, when the clamping member 12 moves from the locked position to the unlocked position, the clamping member 12 moves along the first surface 1121 toward the second surface 1122, and the clamping member 12 is located on the first surface 1121. Therefore, this design method can effectively reduce the increase in the size of the interface 31 on the surgical instrument 30 caused by the clamping portion 121 when the clamping member 12 is clamped with the surgical instrument 30, thereby facilitating the design of the interface 31 on different types of surgical instruments 30, so that the alignment handle 10 can be adapted to more types of surgical instruments 30.

[0046] In other embodiments, Figure 2 As shown, the alignment handle 10 includes an elastic member 13, which is connected between the clamping member 12 and the joint portion 112. The driving force received by the clamping member 12 includes the force provided by the elastic member 13 to the clamping member 12 along the second surface 1122 toward the first surface 1121, and the clamping member 12 is used to receive the force and move from the unlocking position to the locking position. In other words, the clamping member 12 can automatically move from the unlocking position to the locking position under the action of the force provided by the elastic member 13, so that after the clamping member 12 and the joint portion 112 are inserted into the interface 31 on the surgical instrument 30, the clamping portion 121 can automatically engage with the surgical instrument 30 under the action of the elastic member 13, so as to achieve self-locking of the alignment handle 10 and the surgical instrument 30.

[0047] In some other embodiments, the clamping member 12 is rotatably connected to the joint portion 112, so that the clamping member 12 can rotate around the rotation axis a between the locked position and the unlocked position, and the extension direction of the rotation axis a forms an angle with the direction of the second surface 1122 toward the first surface 1121. In other words, the clamping member 12 can be rotated relative to the joint portion 112 by pressing, so that the clamping portion 121 rotates between the unlocked position and the locked position, so as to facilitate the rapid assembly and disassembly of the alignment handle 10 and the surgical instrument 30 during the operation, thereby improving the operation efficiency.

[0048] Among them, the clamping member 12 and the joint part 112 can be connected by a pin, that is, pin holes are correspondingly opened on the clamping member 121 and the joint part 112, and the pin passes through the clamping member 12 and the joint part 112 at the same time, so that the clamping member 12 can be rotatably connected with the joint part 112 around the pin axis.

[0049] It should be noted that, in the embodiment of the present application, the position at which the clamping member 12 is rotatably connected to the engaging portion 112 is arranged between the elastic member 13 and the clamping portion 121, so as to ensure that in the process of the clamping portion 121 moving from the unlocking position to the locking position, while the elastic member 13 provides a force along the second direction Y toward the first direction X to the clamping member 12, the clamping portion 121 can also move along the second direction Y toward the first direction X, so that the clamping member 12 can automatically move from the unlocking position to the locking position under the action of the elastic member 13, thereby realizing the self-locking of the alignment handle 10 and the surgical instrument 30.

[0050] Optionally, a mounting groove 1121a is formed on the first surface 1121 of the joint 112, and the clamping member 12 is located in the mounting groove 1121a to reduce the overall thickness of the alignment handle 10, thereby reducing the size of the interface 31 on the surgical instrument 30 for mating with the alignment handle 10, so as to facilitate the design of the interface 31 on the surgical instrument 30, thereby helping the alignment handle 10 to adapt to more surgical instruments 30.

[0051] There is a gap between the clamping part 121 and the bottom surface of the mounting groove 1121a, so that when the clamping part 12 moves from the locking position to the unlocking position, the clamping part 121 can move along the direction of the first surface 1121 toward the second surface 1122. That is to say, when the clamping part 12 is installed in the mounting groove 1121a, it is necessary to allow the clamping part 12 to have enough movable space in the mounting groove 1121a to facilitate the movement of the clamping part 12 between the locking position and the unlocking position. In addition, the bottom surface of the mounting groove 1121a can also play a role of limiting, so as to limit the moving distance of the clamping part 121 in the direction from the first surface 1121 to the second surface 1122, so as to avoid the clamping part 121 directly moving to the second surface 1122 exposed from the joint part 112 when the clamping part 12 is pressed, so that the clamping part 12 cannot be smoothly inserted into the interface 31 on the surgical instrument 30, thereby affecting the rapid assembly of the alignment handle 10 and the surgical instrument 30.

[0052] In some embodiments, Figure 2 and Figure 3 As shown, the mounting groove 1121a extends in the direction of the alignment portion 111 toward the coupling portion 112, and forms a first opening 1123 on the side of the coupling portion 112 away from the alignment portion 111, that is, the side of the coupling portion 112 away from the alignment portion 111 is a U-shaped opening structure, so that when the clamping portion 121 moves between the locking position and the unlocking position, the side of the coupling portion 112 away from the alignment portion 111 will not interfere with it.

[0053] Among them, the orthographic projection of the clamping portion 121 on the bottom surface of the installation groove 1121a is located on the side of the first opening 1123 close to the alignment portion 111, that is, when the clamping portion 121 is inserted into the interface 31 on the surgical instrument 30, the coupling portion 112 can also be partially inserted into the corresponding interface 31, so that the side wall of the inserted part of the coupling portion 112 can abut against the side wall of the interface 31, thereby improving the connection stability between the alignment handle 10 and the surgical instrument 30.

[0054] In other embodiments, a limiting portion 122 is formed on one side of the clamping member 12 close to the alignment portion 111. When the clamping member 12 moves between the locked position and the unlocked position, the limiting portion 122 moves in opposite directions to the clamping portion 121. That is, when the clamping member 12 is rotationally connected to the coupling portion 112, the clamping portion 121 and the limiting portion 122 are respectively located on opposite sides of the rotationally connected position of the clamping member 12 and the coupling portion 112.

[0055] The first surface 1121 of the joint 112 is provided with a limiting groove 1121b. When the clamping member 12 moves from the unlocking position to the locking position, the bottom surface of the limiting groove 1121b is used to abut against the limiting portion 122 to limit the moving distance of the limiting portion 122 in the direction from the first surface 1121 to the second surface 1122. That is to say, when the alignment handle 10 is not used in conjunction with the surgical instrument 30, the clamping member 12 in the alignment handle 10 can be simultaneously subjected to the force of the elastic member 13 and the bottom surface of the limiting groove 1121b. The force of the elastic member 13 prompts the limiting portion 122 to move along the first surface 1121 toward the second surface 1122, and the bottom surface of the limiting groove 1121b prevents the limiting portion 122 from moving along the first surface 1121 toward the second surface 1122, so that the clamping member 12 can maintain force balance when not in use, and will not shake at will, thereby reducing the risk of damage to the alignment handle 10 and increasing the service life of the alignment handle 10.

[0056] Optionally, a plurality of first alignment holes 1111 are provided on the alignment portion 111, and the plurality of first alignment holes 1111 are spaced apart along the direction of the joint portion 112 toward the alignment portion 111, that is, the plurality of first alignment holes 1111 are spaced apart along the length direction of the alignment handle 10, so that during knee joint surgery, the operator can select appropriate first alignment holes 1111 according to the actual situation of the patient, thereby avoiding interference between the vertical alignment rod 20 and human tissue after being inserted into the first alignment hole 1111, thereby making the alignment handle 10 more applicable.

[0057] In some embodiments, the first alignment hole 1111 extends continuously along the joint portion 112 toward the alignment portion 111, that is, the first alignment hole 1111 is in a long strip shape, so that during knee joint surgery, the operator can continuously adjust along the extension direction of the first alignment hole 1111 according to the actual situation of the patient to find the most suitable position, thereby avoiding interference between the vertical wire rod 20 and human tissue after being inserted into the first alignment hole 1111, thereby making the alignment handle 10 have a wider range of applications.

[0058] In other embodiments, the alignment portion 111 is further provided with a second alignment hole 1112, which penetrates the alignment portion 111 along a second direction Y, and the second direction Y forms an angle with the first direction X. The second alignment hole 1112 is used for inserting a vertical line rod 20, so as to perform vertical line verification for different types of surgical instruments 30 through the vertical line rod 20. The second direction Y refers to the width direction of the alignment handle 10, that is, the direction perpendicular to the vertical line when performing vertical line verification, that is, when performing vertical line verification, it is possible to assist in judging whether the corresponding surgical instrument 30 is adjusted to the target position according to whether the axial direction of the vertical line rod 20 inserted into the second alignment hole 1112 is perpendicular to the vertical line of the corresponding position.

[0059] Optionally, the alignment handle 10 further includes a rubber coating 14, which is wrapped around the outer surface of the alignment portion 111. The rubber coating 14 is provided with a second opening 141 at a position corresponding to the first alignment hole 1111, so that the vertical line rod 20 can pass through the second opening 141 and be inserted into the first alignment hole 1111. When performing vertical line verification, the alignment portion 111 of the alignment handle 10 is the main gripping area. By wrapping a layer of rubber coating 14 on the outer surface of the alignment portion 111, the friction force when the operator grips can be increased, and the gripping stability can be improved; at the same time, the rubber coating 14 forms an arc-shaped plane at the operator's gripping position, and the arc-shaped plane is used to fit the operator's palm to obtain a more comfortable gripping feeling, thereby improving the operator's operating experience.

[0060] It should be noted that if Figures 4 to 7 As shown, the surgical instrument 30 in the embodiment of the present application includes at least two of the distal femoral osteotomy block 32, the proximal tibial osteotomy block 33, the flexion-extension gap measurer 34 and the tibial support trial mold 35, that is, the alignment handle 10 in the embodiment of the present application is compatible with various surgical scenarios that require alignment during knee joint surgery without the need for additional instruments, thereby helping to improve surgical efficiency.

[0061] Secondly, an embodiment of the present application also provides a knee joint surgery line verification tool, which includes an alignment handle. The specific structure of the alignment handle refers to the above embodiment. Since the knee joint surgery line verification tool adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0062] like Figures 4 to 7 As shown, the knee joint surgery alignment verification tool 1 includes an alignment handle 10, a first surgical instrument, a second surgical instrument and an alignment rod 20. The first surgical instrument and the second surgical instrument are surgical instruments 30 of different types, that is, the first surgical instrument and the second surgical instrument can be at least two of the distal femoral osteotomy block 32, the proximal tibial osteotomy block 33, the flexion-extension gap measuring device 34 and the tibial tray trial mold 35. The alignment rod 20 is used to be inserted into the first alignment hole 1111 on the alignment handle 10 to perform alignment verification on the first surgical instrument and the second surgical instrument.

[0063] Among them, the first surgical instrument and the second surgical instrument are provided with the same interface 31, and the interface 31 is used for detachable connection with the alignment handle 10. By setting the interfaces 31 on different types of surgical instruments 30 to be the same, during the knee joint surgery, only one alignment handle 10 is needed to achieve mutual coordination with the line pole 20 and different types of surgical instruments 30, so as to realize the line verification of different positions in the knee joint surgery, thereby reducing the types and quantities of instruments required in the knee joint surgery, and then effectively simplifying the coordination process between the alignment handle 10 and different types of surgical instruments 30, thereby improving the surgical efficiency.

[0064] It should be noted that the first surgical instrument and the second surgical instrument are only used to represent different types of surgical instruments 30, and do not mean that there are only two types of surgical instruments 30, but refer to various surgical instruments 30 that need to be checked for alignment during knee joint surgery. The specific structure of the alignment handle 10 can refer to the relevant description in the above embodiment, and will not be repeated here.

[0065] Specifically, when using the knee joint surgery vertical line verification tool 1 to verify the vertical line, the surgical instrument 30 is placed at the corresponding position during the knee joint surgery, and the joint 112 and the clamping part 12 of the alignment handle 10 are matched and connected with the interface 31 on the surgical instrument 30. According to needs, the vertical line rod 20 is inserted into the first alignment hole 1111, or the vertical line rod 20 is inserted into the first alignment hole 1111 and the second alignment hole 1112 respectively. Then, the position of the surgical instrument 30 is adjusted according to the relationship between the axis of the vertical line rod 20 and the vertical line at the corresponding position to ensure that the surgical instrument 30 is adjusted to the target position to facilitate the smooth progress of the operation.
