Problems solved by technology

[0005] (1) In bone graft surgery, taking autologous iliac crest needs to increase the trauma of the patient, while using allogeneic bone or artificial bone is prone to rejection
[0006] (2) For patients who have undergone autologous ilium bone grafting, there will be no place to take bone when repeat surgery is required

Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] Such as figure 1 As shown, the limb long bone metaphysis bone extractor provided by the embodiment of the present invention includes: an outer sleeve 1 , an inner core 2 , and a ring saw 3 .

[0022] An inner core 2 is installed inside the outer sleeve 1, and the length of the inner core 2 is equivalent to that of the outer sleeve 1. The end of the inner core 2 contacts the middle ring saw 3, and the end of the middle ring saw 3 is set in a sawtooth shape.

[0023] As a preferred embodiment, the diameter of the outer sleeve 1 matches the size of the corresponding intramedullary nail.

[0024] As a preferred embodi...

Abstract

The invention belongs to the technical field of medical technology, and discloses a limbs long bone metaphysis bone fetcher. The limbs long bone metaphysis bone fetcher is provided with an outer sleeve; the inside of the outer sleeve is internally provided with an inner core, the length of the inner core is equivalent to the outer sleeve, the end of the inner core is in contact with a ring saw, and the tail end of the ring saw is arranged in a zigzag shape. The limbs long bone metaphysis bone fetcher can be perfectly matched with the intramedullary nail system, so that the fixation failure canbe avoided, the intact bone of the limbs long bone metaphysis can be taken out, the bone graft is convenient, the non-healing of the fracture end can be reduced, the iliac or allograft bone or the artificial bone graft can be avoided, and the pain and the financial burden of the patients can be relieved.

Description

technical field [0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a bone extractor for the metaphysis of limbs and long bones. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] During fracture surgery, bone grafting is sometimes required to transplant bone tissue into the patient's body where the bone is missing, needs to be strengthened or fused. Due to the different sources of bone, it can be divided into autologous bone graft and allogeneic bone graft. Autologous bone transplantation generally needs to take bone from the patient's own iliac crest. This bone grafting has no rejection reaction and the effect is good, but at the same time it causes certain trauma to the patient, and resources are limited. Bone grafting surgery, if you want to do another revision operation, it will inevitably lead to an embarrassing situation where there i...
