Novel thyroid surgery drag hook

Abstract

The invention discloses a novel thyroid surgery drag hook, and belongs to the technical field of medical instruments. The novel thyroid surgery drag hook is provided with a mode rotary adjusting piece, so that an outer side hook head can be rotationally adjusted; an inner connecting hook plate, the outer side hook head, an inner hook adjusting piece and a linkage adjusting piece are combined to be arranged, so that novel thyroid surgery drag hook has a one-way use mode and a two-way use mode; when the drag hook is used in the one-way mode, the outer side hook head and an inner side hook head can be clamped to the inner side and the outer side of an anterior cervical muscle group of a patient correspondingly, the situation that the drag hook slides when the anterior cervical muscle group of the patient is pulled can be effectively avoided, and stability is greatly improved; when the drag hook is used in the two-way mode, the anterior cervical muscle group can be pulled in two directions at the same time, so that the use amount of the drag hook can be remarkably reduced, manpower can be reduced, hindrance to operation of a doctor can be greatly reduced, and practicability is greatly improved; compared with an existing right-angle drag hook, the drag hook is diversified in function and high in stability.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and more specifically relates to a novel retractor for thyroid surgery. Background technique [0002] Retractors, also known as retractors, are used to retract tissues to expose the area to be operated on and facilitate exploration and operation. They can be divided into two types: hand-held retractors and automatic retractors. There are various specifications of different shapes and sizes, and the appropriate retractor can be selected according to the operation needs. [0003] In conventional open thyroid surgery, the exposure of the operative field is very critical. For this reason, retractors must be used to pull apart the anterior neck muscles located in front of the thyroid gland. The commonly used retractors in thyroid surgery are right-angled retractors in the shape of flat hooks. [0004] The existing right-angle retractor has a simple structure but single function and poor s...

AI Technical Summary

Problems solved by technology

[0004] The existing right-angle retractor has a simple structure but single function and poor stability. It is prone to slipping during use, and one right-angle retractor can only pull the anterior neck muscles in one direction, resulting in the need for multiple people to hold multiple right-angle retractors for pulling. In order to reveal a sufficient surgical field, it is not only a waste of manpower, but also will inevitably hinder the doctor's operation due to the large number of people.
