Problems solved by technology

At present, there are still two extremes, either for the sake of surgical safety, excessive exposure, ignoring the soft tissue hinge and fracture blood supply, or blindly operating in order to protect the fracture blood supply, there are obvious disadvantages, very helpless
In surgical practice, the most likely to cause accidental injury is the backbone drilling. The drilling operation is not easy to locate, and the accuracy of the drilling is not easy to ensure. The contradiction between tissue exposure and protection of the periosteum and soft tissue hinges is more prominent.

Embodiment Construction

[0014] The present invention will be further described in conjunction with the accompanying drawings of the above-mentioned embodiments.

[0015] As shown in the figure, the backbone drilling protector of the present invention has a guide sleeve 6 with a drill hole 8, one end of the guide sleeve 6 is connected to the C-shaped backbone support handle 2, and the front end of the C-shaped backbone support handle 2 doubles as The drill baffle, the drill baffle is provided with a drill drop groove 1, the drill baffle corresponds to the center line of the drill hole 8, the guide sleeve 6 is equipped with a slider 3, and the rear end of the slider 3 is equipped with a return spring 7. The toggle handle 4 on the slider 3 is placed in the chute 5 of the guide sleeve 6 .

[0016] When performing the operation, push the toggle handle 4 backward to make the slider 3 retreat, insert the C-shaped backbone support handle 2 into the opposite side of the backbone, make the front end close to t...

Abstract

A diaphysis drilling protector for ensuring correct drilling on diaphysis and protecting periost and soft tissue has a guiding sleeve pipe with a drilling hole, and a C-shaped diaphysis supporting handle with a front end used as the barrier plate of drill bit.

Description

technical field [0001] The invention relates to a protector in backbone drilling operation, which belongs to clinical operation instruments. Background technique [0002] In extremity surgery, how to achieve clear exposure, avoid accidental injury, and at the same time protect the periosteum and soft tissue hinges as much as possible, and save the blood supply of fracture ends and fragments is an unsolved problem. At present, there are still two extremes, either for the sake of surgical safety, exposing beyond the scope, ignoring the soft tissue hinge and fracture blood supply, or blindly operating in order to protect the fracture blood supply, there are obvious disadvantages, very helpless. In surgical practice, the most likely to cause accidental injury is the drilling of the backbone. The positioning of the drilling operation is difficult, and the accuracy of the drilling is not easy to ensure. The contradiction between tissue exposure and protection of the periosteum and...
