Problems solved by technology

The Ligasure energy platform is bipolar electrocoagulation plus real-time feedback technology and intelligent host technology. The temperature of the blade is low and the lateral heat conduction is relatively small. However, in the application of thyroid surgery, the thicker blade can hardly achieve a fine coating Dissection operation also has a lot of inconvenience in the operation of protecting the recurrent laryngeal nerve and superior laryngeal nerve, and its high cost limits its application in the field of thyroid surgery

Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] The purpose of the present invention is to provide a bipolar electric coagulation forceps with airgel coating, which can solve its potential side effects to the greatest extent while retaining the advantages of bipolar electric coagulation forceps in fine operation in thyroid surgery. Heat conduction may cause damage to the recurrent laryngeal nerve and superior laryngeal nerve.

[0023] In order to make the above objects, features and advantages of the...

Abstract

The invention discloses a bipolar electrocoagulation forceps with aerogel coating for thyroid surgery, comprising a forceps holder, a first forceps piece, a second forceps piece, a first metal forcepstip and a second metal forceps tip. One end of the first forceps piece and one end of the second forceps piece are respectively arranged on the forceps holder. The fixing part of the first metal forceps tip is arranged at the other end of the first forceps sheet, and the fixing part of the second metal forceps tip is arranged at the other end of the second forceps sheet. The inner working ends ofthe first metal forceps tip and the second metal forceps tip are made of silver alloy, and are partially coated with aerogel material except the working end of the first metal forceps tip and the working end of the second metal forceps tip. The electric coagulation forceps can solve the problem of injury of recurrent laryngeal nerve and superior laryngeal nerve caused by lateral heat conduction in the application of thyroid surgical energy instruments.

Description

technical field [0001] The invention relates to the field of surgical instruments, in particular to a bipolar electric coagulation forceps for thyroid surgery with an airgel coating. Background technique [0002] Bipolar electric coagulation forceps are often used in thyroid surgery. In recent years, more and more energy devices have been used in thyroid surgery. However, hoarseness, coughing when drinking water, and Complications such as deep voice have always been a hot spot in the industry. The analysis found that the lateral heat conduction of energy devices is one of the important causes of nerve damage. High-frequency electric knife is the most traditional electrosurgical instrument. Its principle is to use the pulse time and extremely short high-frequency current to trigger the heat energy generated by the vibration of ions in human tissue in viscous body fluid. The maximum instantaneous temperature of the high-frequency electric scalpel can reach 400°C, and it is d...
