Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.
As shown in fig. 1 to 3, the intervertebral prosthetic implant tool includes: a frame 10, a measuring part 20 and a polishing part 30. The frame 10 has a reference surface 14. The measuring section 20 is provided on the frame body 10 movably in the horizontal direction and floatably in the vertical direction. The measuring part 20 has a depth measuring state moving in a horizontal direction to extend into the human body intervertebral space and a height measuring state floating in a vertical direction and abutting against the human body vertebral body. When the measuring section 20 is in the depth measuring state, the measuring section 20 moves in the horizontal direction so as to protrude from the reference surface 14. The grinding section 30 is provided on the measuring section 20. When the measuring part 20 is in a height measuring state, the measuring part 20 is abutted with the human vertebral body through the polishing part 30, and the polishing part 30 is used for polishing the human vertebral body.
By applying the technical scheme of the embodiment, the measuring part 20 is in a depth measuring state moving along the horizontal direction, so that the measuring part 20 is moved into a gap between two human vertebrae, and the measuring part 20 floats along the vertical direction, so that the polishing part 30 can polish the human vertebrae. After polishing is completed, the measuring part 20 is in a height measuring state floating in the vertical direction, and the polishing part 30 is abutted with the human vertebrae, so that the measuring part 20 can measure the distance between the two human vertebrae through the polishing part 30. The measuring part 20 is in a depth measuring state moving along the horizontal direction, the reference surface 14 is abutted against a first side wall of the human body vertebral body (namely, a side edge of one end of the vertebral body end plate), and the end part of the measuring part 20 extends into a gap between the vertebral bodies of the human body and moves to a second side wall of the vertebral body opposite to the first side wall, so that the depth of the gap between the vertebral bodies of the human body is measured through the measuring part 20. Therefore, the intervertebral prosthesis implantation tool can polish the human vertebrae and measure the distance between the human vertebrae and the depth of the gaps, so that the specification of the implanted prosthesis which is required to be screened in a test mode in the related technology is avoided, and the damage to the human vertebrae is reduced. Therefore, the technical scheme of the embodiment effectively solves the problem that the specification of the implanted prosthesis is screened in a test mode in the related technology, and the vertebral body of the human body is easily damaged.
It should be noted that "the measuring portion 20 is movable in the horizontal direction" and "the measuring portion 20 is floatable in the vertical direction" refer to the movement and the floating direction of the intervertebral prosthetic implantation tool in the use state.
By applying the technical scheme of the embodiment, the heights of different positions in the gaps between the vertebral bodies of the human body can be continuously measured, and the measurement efficiency is improved. And the height and longitudinal length dimensions of the applicable prosthesis 60 can be derived from the measured height and depth verticals to determine the model and gauge of the prosthesis 60. Further, the frame body 10 includes a frame body 11 extending in a horizontal direction. The two measuring parts 20 are provided at the upper and lower sides of the rack body 11 opposite to each other, and the two measuring parts 20 can float in the vertical direction with respect to the rack body 11 to be close to or apart from each other. The upper measuring part 20 can be abutted with the upper human body vertebral body through the arrangement of the upper measuring part 20 and the lower measuring part 20, and the lower measuring part 20 can be abutted with the lower human body vertebral body, so that the accuracy and the efficiency of height measurement are improved. The intervertebral prosthesis implantation tool further comprises a clamping structure movably arranged on the frame body 11, the clamping structure is clamped on the outer sides of the two measuring parts 20, and the clamping structure moves to drive the two measuring parts 20 to be close to each other. This allows an operator to drive both measuring sections 20 to float via the clamping structure, facilitating adjustment of the measuring sections 20 during height measurement.
As shown in fig. 1 to 3, a rotation shaft is provided on the rack body 11. The clamping structure comprises a first clamping piece 41 and a second clamping piece 42 which are arranged in a crossing mode, and the first clamping piece 41 and the second clamping piece 42 are arranged on the frame body 11 in a penetrating mode through the rotating shaft in a rotatable mode. The spindle has a first side remote from the measuring portion 20 and a second side close to the measuring portion 20. The first clamping member 41 includes a first operating handle 411 disposed at a first side of the rotation shaft and a first clamping arm 412 disposed at a second side of the rotation shaft, and the second clamping member 42 includes a second operating handle 421 disposed at the first side of the rotation shaft and a second clamping arm 422 disposed at the second side of the rotation shaft. The first clamping arm 412 is located outside one measuring section 20 and the second clamping arm 422 is located outside the other measuring section 20. The first and second handles 411 and 421 are moved closer to each other to bring the two measuring portions 20 closer to each other by the first and second clamp arms 412 and 422. The clamping structure is simple in structure, and the two measuring parts 20 can be clamped by the first clamping piece 41 and the second clamping piece 42 which are arranged in a crossing manner, and the two measuring parts 20 are driven to be close to each other by driving the first operating handle 411 and the second operating handle 421 to be close to each other.
In this embodiment, before the measuring portion 20 is moved to the space between the two human vertebrae, the two measuring portions 20 are driven to approach each other by the clamping structure, so that the two measuring portions 20 can more smoothly enter the space between the two human vertebrae. One measuring part 20 is movable relative to the first clamping arm 412 and the other measuring part 20 is movable relative to the second clamping arm 422.
As shown in fig. 1 to 3, the frame body 10 includes a frame body 11 extending in a horizontal direction, and a rail 16 extending in the horizontal direction is provided on the frame body 11. The measuring part 20 includes a connecting member 21, a measuring member 22, and an elastic member 23. The connecting member 21 is movably provided on the frame body 11, and a guide sleeve 27 is provided on the connecting member 21 to be in guide-fit with the guide rail 16. The guide rail 16 and the guide sleeve 27 enable the connecting piece 21 to move along the guide direction of the guide rail 16, so that the movement of the measuring part 20 is smoother, and the measuring part 20 can be moved into the gap between the vertebral bodies of the human body conveniently. The measuring member 22 is floatably connected to the connecting member 21 by an elastic member 23 so that the measuring member 22 can move in synchronization with the connecting member 21 and float in the vertical direction with respect to the connecting member 21. The elastic member 23 is provided such that the measuring member 22 can float in the vertical direction with respect to the connecting member 21, and the elastic member 23 is provided such that the measuring member 22 is driven to move synchronously when the connecting member 21 moves. When the measuring member 22 enters the space between the vertebral bodies of the human body, the elastic member 23 is compressed so that the measuring member 22 can abut against the vertebral bodies of the human body.
In this embodiment, the driving connector 21 can drive the measuring member 22 to move in the horizontal direction. An operating handle is provided on the side of the connecting piece 21 facing away from the reference surface 14 to facilitate the driving operation of the connecting piece 21 by an operator.
As shown in fig. 1 to 3, the connecting member 21 is provided with a connecting rod 24, the measuring member 22 is provided with a connecting hole, and the connecting rod 24 is inserted into the connecting hole. The connecting rod 24 and the connecting hole enable the connecting piece 21 to more reliably drive the measuring piece 22 to move when moving, so that the synchronous movement of the measuring piece 22 and the connecting piece 21 is smoother and more reliable. When the measuring member 22 floats relative to the connecting member 21, the connecting hole is in plug-in engagement with the connecting rod 24. Thus, when the measuring piece 22 floats, the connecting piece 21 can drive the measuring piece 22 to synchronously move through the plug-in cooperation of the connecting rod 24 and the connecting hole. When the measuring piece 22 floats, the depth of the connecting rod 24 inserted into the connecting hole changes, so that the measuring piece 22 can float along the vertical direction and the connecting rod 24 can drive the measuring piece 22 to synchronously move.
In the present embodiment, the elastic member 23 is preferably a compression spring. When the elastic member 23 is in a natural state, i.e., the compression spring is not subjected to an external force, there is a space between the end of the connecting rod 24 and the bottom wall of the connecting hole, and the connecting rod 24 is inserted into the connecting hole, the elastic member 23 is compressed when the measuring member 22 floats, and the space between the end of the connecting rod 24 and the bottom wall of the connecting hole is reduced.
As shown in fig. 1 to 4, the frame body 10 includes a frame body 11 extending in a horizontal direction and a reference frame 12 provided on an end of the frame body 11. The reference surface 14 is provided on a side of the reference frame 12 away from the frame body 11, and the reference frame 12 is surrounded outside the measuring section 20 and the polishing section 30. Thus, the reference frame 12 can be abutted against the side surface of the human body vertebral body, the reference surface 14 on the reference frame 12 can be used as a reference, and the distance that the measuring part 20 and the polishing part 30 extend into the gap between the human body vertebral body can be conveniently obtained by measuring the distance that the measuring part 20 and the polishing part 30 protrude from the reference surface 14. The reference frame 12 is simple in structure and convenient to process. Further, the grinding section 30 includes a grinding head 31, a transmission member 32, and a driving member 33. The grinding head 31 is rotatably provided on the measuring part 20, and the grinding head 31 is rotated so as to grind the vertebral body of the human body.
