Detailed Description
The technical solutions of the present application will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, not all, of the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1 and 2, the present embodiment provides an acetabular file 100 and, for ease of illustration of the version of the present application, a tracer 200 is shown in fig. 2. The acetabular file 100 comprises a bearing 1, an acetabular file body 2 and a retaining structure 3.
As shown in fig. 3, the stand 1 includes a sleeve 11 and a support rod 12. In this embodiment, the sleeve 11 is substantially cylindrical, and the support rod 12 is disposed on the outer wall of the sleeve 11, and the axis of the support rod 12 is perpendicular to the axis of the sleeve 11. The support rod 12 is used to connect the tracer 200. The sleeve 12 is provided with a through hole 13, and the through hole 13 extends along the axis of the sleeve 12.
As shown in fig. 4, the acetabular bone file main body 2 comprises a filing head 21 and a connecting rod 22, wherein the filing head 21 is arranged at one end of the connecting rod 22, and the connecting rod 22 can drive the filing head 21 to rotate. The connecting rod 22 rotatably passes through the through hole 13 of the sleeve 11. When the acetabulum grinding device is used, the driver drives the connecting rod 22 to rotate, and the connecting rod 22 drives the filing head 21 to rotate so as to grind the acetabulum.
The limiting structure 3 is arranged on the connecting rod 22, and the limiting structure 3 limits the sleeve 11 of the support 1 to slide along the axis of the connecting rod 22, so that only relative rotation between the connecting rod 22 and the sleeve 11 is ensured.
When the acetabulum needs to be ground, the tracer 200 is connected to the support rod 12, and the filing head 21 is aligned to the acetabulum for grinding. The doctor, by holding the support 1, ensures that the sleeve 11 does not follow the rotation of the link 22. The navigation system of the surgical robot can identify the tracer 200, thereby determining the position of the acetabular file 100, and further calculating the angle of the connecting rod 22 relative to the acetabulum and the depth of the filing head 21 into the acetabulum. The angle and the depth of the acetabular grinding can be accurately controlled by a doctor through the acetabular file 100 of the embodiment, and the quality of the operation is improved.
As shown in fig. 5, the bush 11 is provided at both ends thereof with bushes 4, respectively, the bushes 4 are fitted into the through-holes 13, and the link 22 rotatably penetrates the bushes 4. The bush 4 is arranged between the connecting rod 22 and the sleeve 11, so that when the connecting rod 22 rotates, the direct contact friction between the connecting rod 22 and the sleeve 11 is avoided, and the service life of the acetabular file 100 is prolonged. The lining can be made of hydrogen peroxide or PEEK material sterilized by moist heat, and has high wear resistance.
As shown in fig. 6, the damping structure 5 is provided on the inner wall of the sleeve 11, and the damping structure 5 is in contact with the connecting rod 22. The damping force applied by the damping structure 5 to the link 22 blocks the rotation of the link 22. The damping structure 5 exerts a small damping force on the link 22, and basically does not influence the driver to drive the link 22 to rotate. When the connecting rod 22 is not required to rotate, the damping structure 5 can prevent the sleeve 11 and the connecting rod 22 from rotating relatively, and the safety of the operation is improved.
In an alternative, the inner wall of the sleeve 11 is provided with a groove 111. Optionally, the portion of the outer wall of the sleeve 11 corresponding to the groove 111 is provided with a protrusion 15, and the groove 111 extends to the protrusion 15 to increase the depth of the groove 111. The damping structure 5 comprises damping beads 51 and a resilient member 52. In this embodiment, the damping beads 51 are steel beads, the damping beads 51 are located in the grooves 111, and the top curved surfaces of the damping beads 51 extend out of the grooves 111 to contact the connecting rod 22. The elastic member 52 may be selected as a spring, and the elastic member 52 is located between the damping bead 51 and the bottom surface of the groove 111. The elastic force of the elastic member 52 presses the damping bead 51 against the link 22 to apply a damping force to the link 22. The damping structure 5 may be other forms of damping structures as desired.
According to an optional technical scheme of this application, be equipped with cleaning hole 14 on the lateral wall of sleeve 11, cleaning hole 14 and through-hole 13 intercommunication. After the acetabular file 100 is used up, dirt in the through hole 13 is cleaned through the cleaning hole 14, and the acetabular file 100 can be used next time conveniently. Alternatively, the number of the cleaning holes 14 is plural, and the plural cleaning holes 14 are circumferentially and evenly distributed around the axis of the sleeve 11.
Optionally, the cleaning aperture 14 is an oblong hole. The long sides of the oblong holes extend parallel to the axis of the sleeve 11, facilitating the cleaning of the through holes 13.
According to an alternative embodiment of the present application, the limiting structure 3 comprises two limiting rings, and the limiting rings are fixedly disposed on the connecting rod 22. In this embodiment, the two limiting rings are respectively located at the outer sides of the two bushings 4, and the two limiting rings limit the support 1 to slide along the axis of the connecting rod 22. The limiting structure 3 can be set into other limiting structures such as pins and the like according to requirements.
As shown in fig. 4, the end of the connecting rod 22 opposite to the filing head 21 is provided with a driver joint 211. The driver joint 211 is used for being connected with a driver, and the driver drives the connecting rod 22 and the filing head 21 to rotate so as to grind the acetabulum.
As shown in FIG. 7, the support rod 12 is provided with a positioning structure 121, and the positioning structure 121 is used for positioning the tracer 200. The positioning structure 121 of this embodiment is a positioning hole disposed on the top surface of the supporting rod 12, and the positioning hole is matched with the positioning post of the tracer 200 to position the supporting rod 12 and the tracer 200.
