Description

Technical Field

[0001] The present invention relates to the technical field of thyroid surgical equipment, and more particularly, to a convertible separating forceps for endoscopic thyroid surgery. Background Art

[0002] In endoscopic thyroid surgery, the separating forceps is the most common surgical instrument, which is mainly applied in the following aspects: Tissue separation: During the separation of the thyroid gland from surrounding structures (such as the trachea, esophagus, etc.), the separating forceps can be used to lift tissues to assist sharp or blunt separation; Tissue traction: The separating forceps is used to traction thyroid tissues or other surrounding tissues to provide a better surgical field of view and operating space; Tissue fixation: During delicate operations, the separating forceps can help fix tissues to prevent their movement, enabling surgeons to perform surgeries more precisely.

[0003] Currently, the commonly used endoscopic separating forceps on the market have relatively fixed head end arcs and joints, with small mobility and limited adjustment ranges, which have certain limitations in surgeries with small operating spaces, such as endoscopic thyroid surgery, causing difficulties in operations such as separating the recurrent laryngeal nerve and cleaning lymph nodes, and the mutual limitation between instruments may cause secondary injuries.

[0004] In view of this, we now propose a convertible separating forceps for endoscopic thyroid surgery to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a convertible separating forceps for endoscopic thyroid surgery, which has a simple structure, is easy to use, and can quickly replace the separating forceps head.
