Problems solved by technology

[0002] In orthopedic surgery, it is often necessary to use a bone drill to drill a bone canal on the bone, and then introduce sutures or other surgical instruments into the bone canal. If it is opened, it will be filled with a large amount of blood and soft tissue in the human body, making it difficult to reposition the specific position of the bone tunnel under arthroscopy. As a result, the operation time will be greatly prolonged and the operation risk will be increased.
[0003] At present, there is a lack of relevant positioning tools. In order to facilitate the positioning of the bone canal and the introduction of sutures during surgery, doctors often choose to expand the diameter of the bone canal, which will cause more bone loss and increase the risk of iatrogenic fractures
Currently, there is a lack of positioning and measuring tools for the bone canal, and it is difficult to find the specific position of the bone canal under arthroscopy, and because the diameter of the bone canal is small, it is often necessary to expand the bone canal to introduce sutures smoothly, which causes more injuries. Loss of bone mass, increasing risk of iatrogenic fractures

Abstract

The invention discloses a bone tunnel spacer which comprises a bone tunnel spacer rod and a plug embedded with the bone tunnel spacer rod, wherein the bone tunnel spacer rod is a hollow rod, and scales are marked on a rod body of the bone tunnel spacer rod. After being screwed into a bone tunnel, the bone tunnel spacer can help a doctor to establish a stable and clear instrument channel, has a measurement function and can measure the depth of the bone tunnel.

Description

technical field [0001] The invention relates to the technical field of channel opening in orthopedic surgery, in particular to a bone canal spacer. Background technique [0002] In orthopedic surgery, it is often necessary to use a bone drill to drill a bone canal on the bone, and then introduce sutures or other surgical instruments into the bone canal. If it is opened, it will be filled with a large amount of blood and soft tissue in the human body, making it difficult to relocate the specific position of the bone tunnel under arthroscopy. As a result, the operation time will be greatly prolonged and the operation risk will be increased. [0003] At present, there is a lack of related positioning tools. In order to facilitate the positioning of the bone canal and the introduction of sutures during surgery, doctors often choose to expand the diameter of the bone canal, which will cause more bone loss and increase the risk of iatrogenic fractures. Currently, there is a lack ...
