Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be pointed out that for those of ordinary skill in the art, a number of modifications and improvements can be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0015] See figure 1 and figure 2 , Is a structural exploded schematic diagram of a bone connection device provided by the present invention. The bone connection device includes an acetabular cup connection frame 10 for connecting with an acetabular cup (not shown), and a pubic bone connection frame 11 arranged on the acetabular cup connection frame 10. The bone connecting device can be made of metal material as a whole.

Abstract

The invention provides a bone connector which comprises an acetabular cup connecting rack and a pubic connecting rack. The acetabular cup connecting rack is used for being connected with an acetabular cup. The pubic connecting rack is disposed on the acetabular cup connecting rack. The acetabular cup connecting rack comprises an adjusting rack and a circular slider disposed in the same. The circular slider is connected with the acetabular cup and is capable of sliding lengthwise along the adjusting rack. The adjusting rack is provided with a bolt. The pubic connecting rack is screwed to the bolt and comprises a conical bar used for being connected with human pubis. The slider is circular and capable of sliding lengthwise along the adjusting rack, so that the acetabular cup is capable of rotating with the slider on the adjusting rack and sliding lengthwise along the adjusting rack, and the acetabular cup is adjusted in three directions. Therefore, adjustment is made according to actual conditions as far as possible during surgery. In addition, the bone connector is made of easy fitting structures such as bolts and nuts, so that the bone connector can be connected in an assembled manner.

Description

Technical field [0001] The invention relates to a medical human artificial limb, in particular to an adjustable bone connection device. Background technique [0002] There are many types of artificial hip joint designs in the field of clinical medical engineering, and tumor-type artificial hip joints are one of them. Tumor-type artificial hip joints mainly include four parts: 1. pelvic prosthesis, 2. acetabular cup, 3. pubic joint device, 4. artificial hip prosthesis. Pubic connection device is used for tumor-type artificial hip joint to realize the connection and positioning of pelvis, femur and pubic bone. [0003] The existing tumor-type artificial hip joint prosthesis pubic bone connection device is mainly a nail plate structure, and a customized steel plate is used to connect the acetabular cup and the pubic bone surface with screws. The shortcomings of this type of pubic connection device are obvious, mainly in the inability to realize the assembled connection, and it is di...
