Thread type double-pole electrocoagulator

Abstract

The present invention relates to a linear bipolar electric coagulator which comprises a pair of electric coagulating heads (1), wherein, each electric coagulating head (1) consists of an electrode head (2), an electrode cover (5) and a forceps head cover (3); the back of the electrode head (2) is expanded to be covered inside the electrode cover (5); the back of the electrode cover (5) is expanded to form the forceps head cover (3). The electric coagulating heads (1) are sheathed at a forceps head of various kinds of biting forceps to be penetrated into the operation cavity for the electric coagulating hemostasis of various kinds of positions. The linear bipolar electric coagulator of the present invention can be matched with the biting forceps of various kinds of shapes and is fit for the electric coagulating hemostasis of each position inside nose and skull base, which has the advantages of simple structure and low cost and being one-off and convenient for using.

Description

technical field [0001] The invention relates to a medical instrument for nasal endoscopic surgery, in particular to a line type bipolar electric coagulator. Background technique [0002] Transnasal endoscopic surgery is a milestone in rhinology surgery. After nearly 70 years of development, the surgical indications of nasal endoscopic surgery have been continuously expanded, and the restricted area of ​​surgery has been continuously broken. For the treatment of nasal sinus tumors and skull base lesions, nasal Endoscopic technology has begun to show its advantages, which also put forward higher requirements for other surgical instruments. Among them, the development of surgical forceps is the most perfect, and various shapes of forceps can basically meet the needs of surgery, while hemostasis The current methods are limited to compressing or adding vasoconstrictors such as epinephrine to cotton pads. The bipolar coagulator commonly used clinically is forceps type. In the dee...

AI Technical Summary

Problems solved by technology

In recent years, bipolar coagulation forceps have been developed in laparoscopic surgery and neurosurgery. The wire is placed in the sliding rod, and the two teeth of the bipolar coagulation forceps are tightened by pulling the sliding rod to perform electrocoagulation. When tightening the two teeth of the bipolar coagulation forceps, the hand should move forward in coordination. In the narrow and fragile operation cavity of the nasal skull base, the operation requirements are relatively high, and its shape is single and the clamping force is weak, so it is not applicable Due to the variable angle and strong rigidity of the nasal skull base surgery and the limited space, due to the narrow surgical area of ​​the nasal skull base, surgical instruments of different shapes are required for different parts of the surgical area. At present, there is a lack of a clinical Bipolar coagulator for treating bleeding in different parts
