Embodiment Construction

[0038] The following is attached Figure 1-6 The application is described in further detail.

[0039] The embodiment of the present application discloses a double-action pelvic canine joint prosthesis. refer to figure 1 , a double-moving pelvic canine joint prosthesis comprising a pelvic main body 1, an acetabular outer cup 2 is movably connected to the pelvic main body 1, an acetabular outer cup 2 is internally fixed and connected to an acetabular liner 3, and an inner acetabular liner 3 is movably connected to a ceramic The ball head 5 is fixedly connected to the ceramic ball head 5 with a short handle 6 of trabecular bone. After the pelvic main body 1 is implanted, because the pelvic main body 1 is movably connected with the acetabular outer cup 2, and the acetabular lining 3 is movably connected with the ceramic ball head 5, the pelvic canine joint prosthesis forms a double-moving structure, which expands the pelvic canine joint prosthesis. range of activities of the bo...

Abstract

The invention relates to a double-acting pelvic dog joint prosthesis, and relates to the field of animal joint prostheses, the double-acting pelvic dog joint prosthesis comprises a pelvic main body and an acetabular outer cup movably connected in the pelvic main body, an acetabular lining is fixedly connected in the acetabular outer cup, a ceramic ball head is movably connected in the acetabular lining, and a bone trabecula short handle is fixedly connected to the ceramic ball head. The pelvic dog joint prosthesis has the advantages that the moving angle of the bone trabecula short handle and the pelvic main body is enlarged, the moving range of the pelvic dog joint prosthesis in an animal joint is enlarged, and the normal physiological activity of the animal is met.

Description

technical field [0001] The present application relates to the field of animal joint prosthesis, in particular to a double-action pelvic canine joint prosthesis. Background technique [0002] Pelvic bone tumor is a common disease among pelvic injuries. The treatment methods for pelvic tumors are mainly various pelvic tumor resection and reconstruction operations. The main reconstruction methods include artificial prosthesis reconstruction, joint fusion, autologous tumor bone inactivation, and allogeneic bone reconstruction. At present, artificial pelvic canine joint prosthesis is mainly used for reconstruction treatment of animals. [0003] The pelvic canine joint prosthesis consists of a pelvic body and a short trabecular stem capable of moving on the pelvic body. During the reconstruction treatment, the pelvic canine joint prosthesis is implanted in the animal body, so that the pelvic canine joint prosthesis is used to replace the acetabular rotation center of the animal,...
