Abstract

The invention discloses a femoral head interior support device. The femoral head interior support device comprises a cylindrical support body with a net structure, wherein a hemispherical support part with the net structure is arranged at the front end of the support body, and a fixation component used for fixing the support body on the femoral head is arranged at the tail end of the support body. The femoral head interior support device provided by the invention has the advantages that the support body is implanted into the femoral head, the support part at the front end of the support body supports the femoral head, the fixation component is utilized and fixed on a bone outside the femoral head, and the support body and the support part of the femoral head interior support device can be fixed at a position where the femoral head is implanted; after the interior support device is fixed, the interior support device can not shift as time goes on, permanent support on the femoral head is guaranteed, mechanical properties of the femoral head are guaranteed, the femoral head cannot collapse any more, and an operation course of a patient can be smoothly carried out.

Description

technical field [0001] The invention relates to a medical device, in particular to a supporting device implanted in a femoral head for supporting the femoral head. Background technique [0002] At present, the bone at the femoral head necrosis is supported to prevent the bone from collapsing, such as the patent number 201520151774.4, the application date is 2015.03.17, and the name is "a mesh support device for the treatment of femoral head necrosis". The disclosed support includes three parts: a head, a body and a tail, and the head, body and tail are connected as one and has an internal hollow structure, the angle between the head and the central axis of the body forms an obtuse angle, and the head is a curved hemisphere , the body is cylindrical, with multiple hexagonal hollow through holes on the body wall, and a hexagonal mesh support on the inner wall. After the supporter is implanted in the head and neck of the femoral head, the hemisphere of the head is placed upward...
