Description

Spiral thyroid retractor

Technical Field

The utility model relates to the field of medical equipment, concretely relates to thyroid gland spiral drag hook.

Background

The traditional method in thyroid surgery is to cut a small opening on the neck of a patient to expose the thyroid gland and then perform the surgery, but keloid scars can be left on the neck of the patient after the surgery, the appearance is affected, and the neck has more open blood vessels, which causes certain difficulty in performing the surgery. With the development of medical science and technology, endoscopic thyroid surgery through armpit or breast, thyroid surgery through armpit incision or breast incision, which is usually to open a small opening at the armpit or breast of a patient, then use a common retractor to insert from the surgical incision of the patient and extend into the neck of the patient, and then use the retractor to pull up the epidermal tissue of the patient, thereby providing a certain operation space for the doctor to perform the thyroid surgery, but the traditional retractor has the defects of limited upward pulling height of the epidermal tissue, narrow and small formed operation space, poor stability in the operation process, and great influence on the operation efficiency.

Therefore, in order to overcome the disadvantages of transcervical, transaxillary or transthoracic thyroid surgery, the existing thyroid surgery is generally prone to surgery from a natural cavity, and can effectively avoid scars left on the epidermis of a human body, for example, deep surgery from the oral cavity. But current thyroid surgery through the oral cavity vestibule is in the operation process, because the incision is less in the human oral cavity, leads to the operation space less, and conventional thyroid drag hook operation has a great deal of inconvenience, and the structure is compact enough, thereby the slippage phenomenon appears easily when colluding and drawing the thyroid gland, thereby be unfavorable for the abundant exposure of thyroid gland to influence operation effect and efficiency.

In order to solve the defects of the prior art, people have long searched for and put forward various solutions. For example, Chinese patent literature discloses an endoscopic thyroid surgery retractor [200420052593.8], which is formed by bending a metal wire. The drag hook body of the drag hook is in a V shape with a wide bottom, one end is a needle point, the other end is continued with the drag hook rod, and the drag hook rod is connected with the drag hook handle.

Above-mentioned scheme has solved the thyroid gland drag hook among the prior art to a certain extent and has been unfavorable for fully exposing the problem of thyroid gland, but this scheme still has a lot of not enoughly, for example: the structure is not compact enough, the antiskid effect is poor, and the like.
