Pull hook for soft tissue channel

Abstract

The invention discloses a pull hook for a soft tissue channel. The pull hook comprises a handle and a working end. The included angle between the handle and the working end ranges from 30 degrees to 60 degrees. The working end is of a semi-cylinder shape or cylinder shape and comprises a handle connecting end, a tail end and a side wall with multiple small holes. The pull hook has the advantages that design is reasonable, the included angle between the working end and the handle is an acute angle, efforts are saved, injury to soft tissue is reduced, it is unnecessary to pull the soft tissue with efforts in use, and the space where the pull hook for the channel is placed is an operation space; all operations including titanium nail driving and bone cutting are completed in the working end and isolated from the surrounding soft tissue to protect the soft tissue; the small holes formed in the side wall of the working end of the pull hook for the channel can contain transbuccal trochar instrumentation and also can drain water.

Description

technical field [0001] The present invention relates to medical instruments, and more particularly, to a retractor for soft tissue tunnels. Background technique [0002] Surgical retractor is one of the most commonly used instruments in surgery. It exposes the operator with the largest possible field of view in the smallest possible incision, and is closely related to improving surgical quality, shortening surgical time, and reducing surgical trauma. Different surgical sites need to use different retractors. Due to the anatomy of the oral and maxillofacial region, the surgical operation space is narrow. In recent years, the minimally invasive endoscopic surgery of the maxillofacial region has increased year by year. The tunnel reaches the operating area, for which special retractor support is required to place the endoscopic system and surgical instruments. [0003] At present, there is no retractor specially used for soft tissue tunnels. The disadvantages of other traditio...

Problems solved by technology

[0003] At present, there is no retractor specially used for soft tissue tunnels. The disadvantages of other traditional retractors: ① In order to expose the operating space as much as possible, the surrounding soft tissues need to be stretched excessively, which often damages important structures such as facial nerves and blood vessels, resulting in complications such as facial paralysis and bleeding; Insufficient protection of the surrounding soft tissue, the soft tissue that cannot be covered by the retractor is easily injured by sharp objects and power drills; ③It is easy to slip off, exposing the blood vessels and nerves that should be protected, causing accidental injury to the operator and misleading the operation; ④Because of the size of the retractor itself, It is easy to block the operating direction of the instrument and interfere with the normal operation of the surgical instrument
