As shown in fig. 1, the impact assembly includes an impact rod 21, an impact seat 2 and an impact hammer (not shown in the figure), the impact seat 2 is fixedly connected to one end of the impact rod 21, after the initial positioning, that is, the positioning plate 1 is placed above the vertebral plate 51 of the patient, the impact seat 2 is abutted to the part of the positioning plate 1 corresponding to the upper part of the body surface 5, then the impact hammer is used to strike the end of the impact rod 21 far from the impact seat 2, so as to transmit the force to the positioning plate 1, and the first positioning nail 11 and the second positioning nail 12 press out traces on the vertebral plate 51, and finally the positioning plate 1 is taken out, thereby completing the precise positioning of the intervertebral space 52.
After the location, stretch into body surface 5 below with the intervertebral foramen mirror from the incision, observe the vestige on the vertebral plate 51, on finding two vertebral plates 51 totally four indentation after alright confirm intervertebral space 52's position to be convenient for find the position of accurate intervertebral space 52 that needs the operation, and only need use X-ray transmission development when tentatively fixing a position, follow-up need not the reuse transmission development and fix a position, reduce the radiation that patient and operating personnel will bear, protection patient and operating personnel.
Example 2
As shown in fig. 3, the embodiment is different from embodiment 1 only in the shape of the positioning plate 1 and the shape of the impact base 2, specifically, one surface of the positioning plate 1 departing from the first positioning pin 11 and the second positioning pin 12 is set as an extrados surface 3, and the middle part of the extrados surface 3 in the length direction is arc-shaped and convex towards the direction close to the body surface 5, so that the contact area between the positioning plate 1 and the body surface 5 is increased, the sliding of the positioning plate 1 relative to the body surface 5 is limited, and the stability of the positioning plate 1 in positioning the indentation is improved.
The two ends of the inner arc surface 31 are provided with stabilizing parts 32, the stabilizing parts 32 are arc-shaped and convex towards the direction close to the body surface 5, and the radian of the positioning plate 1 is matched, so that the stability of the two ends of the positioning plate 1 is improved, and the sliding of the positioning plate 1 on the body surface 5 is further limited when the positioning plate is pressed.
Example 3
As shown in fig. 4, the difference between this embodiment and embodiment 2 lies in that the positioning plate 1 has a different structure, specifically, a limiting plate 4 is disposed on one side of the positioning plate 1 close to the vertebral plate 51, an elastic member, specifically, a spring 41 is connected between the limiting plate 4 and the positioning plate 1, and four springs 41 are disposed on the elastic member; all fixed perpendicularly of the four sides of locating plate 1 has bounding wall 42, and the one side that locating plate 1 was kept away from to bounding wall 42 has seted up spout 43, and four bounding walls 42's spout 43 communicates each other, and limiting plate 4 is along being close to or keeping away from the direction sliding connection in spout 43 of locating plate 1.
The limiting plate 4 is provided with a through hole 44, the extending part 13 and the tip part 14 are all arranged through the through hole 44, when the limiting plate 4 is positioned, the limiting plate 4 is firstly abutted against the vertebral plate 51, after the positioning plate 1 is impacted and is pressed down, the positioning plate 1 drives the tip part 14 to be pressed down to press the vertebral plate 51, due to the elastic force action of the spring 41, the depth of the tip part 14 pressed into the vertebral plate 51 can be limited, the vertebral plate 51 of a patient is protected, in addition, after the tip part 14 is pressed into the vertebral plate 51, the elastic force of the spring 41 is beneficial to the tip part 14 to be separated from the vertebral plate 51, and the problem that the positioning plate 1 is blocked and is difficult to take out is solved.
When locating plate 1 does not receive the impact, the distance that spout 43 is close to the lateral wall of locating plate 1 to the one side that limiting plate 4 deviates from vertebral plate 51 is 1~2mm, in this embodiment, this distance specifically is 2mm, and the toper tip of most advanced portion 14 is located the one side that limiting plate 4 is close to vertebral plate 51 this moment, when locating plate 1 receives the impact, locating plate 1 pushes down towards limiting plate 4 direction, until spout 43 is close to the lateral wall and the 4 butts of limiting plate of locating plate 1, restriction locating plate 1 and most advanced portion 14 continue to push in vertebral plate 51, and the stability of restriction is bigger, make most advanced portion 14 can only stretch out 2mm, in the extrusion trace, better protection vertebral plate 51.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
