Problems solved by technology

During the operation, the diseased femoral head should be removed first, and then the artificial femoral head should be implanted. However, due to the protection of the diseased femoral head by surrounding soft tissues and ligaments, and the hyperplasia and sclerosis of the diseased hip joint, the diseased femoral head is often difficult to remove from the acetabulum
[0003] In the prior art, doctors usually use a spiral-shaped head extractor to vigorously twist the femoral head into the cancellous bone to take out the femoral head. In order to hold the femoral head and prevent rotation, it is necessary to hammer into the head extractor or use Kirschner wires to temporarily stabilize the femoral head. , but it may cause accidental injury to patients and surgeons

Embodiment 1

[0013] A femoral head head removal device, comprising a sleeve (1) and a head removal device. The inside of the sleeve (1) is hollow, and one end is a tine (2); one end of the head remover is a handle (4), and a connecting rod (5) is connected to the handle (4), and one end of the connecting rod is a self- Tapping head (3); the head remover can pass through the hollow structure of the sleeve (1).

[0014] When in use, insert the tines of the sleeve (1) into the surface of the femoral head to obtain a grip on the femoral head and prevent the rotation of the femoral head, and then insert the connecting rod (5) of the head extractor into the sleeve (1), Unscrew the femoral head via the self-tapping threaded head (3) on the connecting rod (5).

Abstract

The invention discloses a medical femoral head taking device. The medical femoral head taking device comprises a sleeve and a head taking device. The sleeve is hollow, and sharp teeth are arranged at one end of the sleeve. A handle is arranged at one end of the head taking device, a connecting rod is connected to the handle, and a self-tapping threaded head is arranged at one end of the connecting rod. The head taking device can penetrate through the hollow structure of the sleeve. The medical femoral head taking device is simple in structure, convenient to operate, and capable of effectively reducing the femoral head taking difficulty, operation time is shortened, and it is guaranteed that operations are smoothly performed.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a medical femoral head head harvesting device. Background technique [0002] At present, total hip replacement and artificial femoral head replacement have become very common and are the most effective way to solve the ultimate joint disease of the hip joint. During the operation, the diseased femoral head should be removed first, and then the artificial femoral head should be implanted. However, due to the protection of the diseased femoral head by surrounding soft tissues and ligaments, and the hyperplasia and sclerosis of the diseased hip joint, the diseased femoral head is often It is difficult to remove from the acetabulum. [0003] In the prior art, doctors usually use a spiral-shaped head extractor to vigorously twist the femoral head into the cancellous bone to take out the femoral head. In order to hold the femoral head and prevent rotation, it is necessary ...
