Description

Multifunctional separation forceps for endoscopic thyroid surgery

Technical Field

The invention relates to the technical field of medical instruments, in particular to a multifunctional separating forceps for endoscopic thyroid surgery.

Background

Endoscopic thyroid surgery is a thyroid surgery operated under a complete endoscope, and is one of the current development directions of thyroid surgery technology. The operation is divided into various endoscopic thyroid operations such as oral surgery, breast milk surgery, full-mammary areola surgery, armpit surgery, retroauricular surgery and the like according to different approaches, and is divided into inflatable and non-inflatable endoscopic thyroid operations according to different cavity building ways. More and more thyroid and parathyroid surgeries can be performed endoscopically. The endoscopic thyroid surgery is an epoch-spanning progress of the traditional open thyroid surgery, and has the advantages of less bleeding, easy tissue amplification, no incision on the neck, beautifying and protection of a functional area and a sensory area in front of the neck.

The endoscopic thyroid surgery needs to use limited instruments in a relatively narrow space to accurately complete the operations such as separation, electrocoagulation and dissociation, so that multifunctional instruments are needed to assist in completing the operations, repeated replacement of the instruments can be avoided, and the operation efficiency is improved. The thyroid operation also relates to the identification and protection of numerous nerves such as recurrent laryngeal nerves, superior laryngeal nerves, vagus nerves, accessory nerves, phrenic nerves, cervical plexus nerves and the like, corresponding complications can be brought about by the damage of the nerves, particularly, the protection of the recurrent laryngeal nerves is the important part of the thyroid operation, the recurrent laryngeal nerves damage can cause postoperative hoarseness and cough caused by drinking water, and inconvenience is brought to the life of patients, the recurrent laryngeal nerves at two sides can cause dyspnea of the patients, the serious patients even suffocate and die, and the nerves can be identified and protected more effectively by a nerve monitoring technology. The combination of endoscopic instruments and electrosurgery is the basis of laparoscopic surgery, and can efficiently perform the processes of separating, pushing, jacking, pressing, picking, stripping, clamping and the like and hemostasis and blood coagulation. In the operation of the endoscopic thyroid surgery, the separating forceps are widely used for fine dissection and can carry out electrocoagulation, particularly bipolar electrode coagulation is particularly important in the endoscopic thyroid surgery, and can be used for accurately stopping bleeding and cutting tissues at the laryngeal point of the recurrent laryngeal nerve and the Berry ligament, so that the probability of thermal injury of the recurrent laryngeal nerve caused by a monopolar electric knife or an ultrasonic knife is reduced.

At present, the bipolar electrocoagulation under the endoscope has the defects that the metal exposed area is large and the precise electrocoagulation operation cannot be carried out, and the neurosurgical forceps under the endoscope only can carry out nerve stimulation but cannot carry out tissue separation, and the defects of poor operation instantaneity and low efficiency caused by carrying out a plurality of operation steps and repeatedly replacing instruments are overcome.

At present, no multifunctional separating forceps can simultaneously have the functions of fine separating forceps, bipolar coagulation forceps and nerve detection.

Therefore, there is a need for a multifunctional separation forceps for endoscopic thyroid surgery, which can perform fine separation and dissection, precise electrocoagulation hemostasis, precise nerve identification and nerve protection in a narrow space under an endoscope.
