Thyroidectomy lacuna tractor of oral approach endoscope

Abstract

The invention discloses a thyroidectomy lacuna tractor of an oral approach endoscope. The tractor comprises a rod body and a hook connected to one end of the rod body, wherein the hook is V-shaped andis of a hollow tubular structure, the hook comprises a puncture part in a straight tube shape and a traction part, bottom ends of the puncture part and the traction part are smoothly connected through an arc connecting part, a beveling needle point is arranged at the top end of the puncture part, and the top end of the traction part is connected with the rod body; and a handle is arranged at oneend, away from the hook, of the rod body. According to the thyroidectomy lacuna tractor of the oral approach endoscope, the tube diameter of the hook is small, so that tractor punctures easily, can easily pull strap muscle, cannot shield the surgery field and has a good exposure effect.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an oral cavity tractor for laparoscopic thyroidectomy. Background technique [0002] At present, the generally used acupuncture-assisted laparoscopic retractor has a large diameter, high resistance when puncturing through the skin, and causes large trauma to the skin, and does not meet the aesthetic requirements. Moreover, the retractor is more suitable for pulling the sternocleidomastoid muscle during endoscopic lateral neck lymph node dissection. There is no retractor for the strap muscle, which is not conducive to retracting the tissue to expose the surgical area to ensure surgical safety. sex and effectiveness. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention provides an oral cavity retractor for laparoscopic thyroidectomy. The retractor has a thin diameter and is easy to puncture. It can easily pull up the ba...
