Automatic retractor device for endoscopic thyroid surgery

Abstract

The invention discloses an automatic retractor device for endoscopic thyroid surgery, which comprises an inner push handle, an inner rod, an inner supporting head, an outer push handle, an outer rod and an outer supporting head. The inner push handle and the inner supporting head are connected to the two ends of the inner rod respectively, the outer push handle and the outer supporting head are connected to the two ends of the outer rod respectively, the inner rod stretches out and draws back in the outer rod, and the inner push handle is located at the same end, on the outer rod, of the outer push handle, the inner supporting head is positioned at the same end of the outer supporting head on the outer rod, a connecting block is arranged on the face, facing the inner rod, of the inner push handle, external threads are arranged on the outer circumferential face of the connecting block, a connecting groove is formed in the face, back to the outer rod, of the outer push handle, internal threads are arranged on the inner circumferential face of the connecting groove, and the connecting block is connected with the connecting groove through the threads.

Description

technical field [0001] The invention relates to a medical device, in particular to an automatic hook device for laparoscopic thyroid surgery. Background technique [0002] In the process of thyroid surgery, because the lymph node is sandwiched between the muscle and the thyroid gland, the medical staff need to make two holes on the patient's skin surface, and then put two medical braces into the patient's body through the two holes, one of which is medical The support applies force to the muscle, and the other medical support applies force to the thyroid, so that the distance between the muscle and the thyroid is widened, preventing the muscle and the thyroid from being close to the lymph nodes, so that enough space can be made to remove the lymph nodes and prevent the lymph node from being resected. Scraping the muscle and thyroid gland while removing the lymph nodes makes it easier to remove the lymph nodes. [0003] The deficiency of above-mentioned technology has: [0...

AI Technical Summary

Problems solved by technology

[0004] 1. Two holes are made on the patient's skin surface, and the patient suffers more damage

[0005] 2. The medical staff need to use two sets of medical supports, and the two sets of medical supports need to keep applying force in opposite directions. The operation steps are relatively cumbersome, and the work intensity of the medical staff is relatively high.
