Electrotome head special for thyroid and neck surgeries

Abstract

The invention discloses an electrotome head special for thyroid and neck surgeries. An electrotome nose is oblique; the upper edge and the lower edge of the electrotome head are parallel; the interval between the upper edge and the lower edge is 2-3mm; the included angle between the oblique edge of the electrotome nose and the upper edge is 45-60 degrees; crossing points of all edges are in arc connection; the oblique edge is 3.0-3.5mm long; the electrotome nose is 3-5cm long; a high-resistance and high-temperature resistant ZrO2 material is coated to the middle part of the electrotome head; the upper edge of the front end part, not coated with the ZrO2 material, of the electrotome head is 3-4mm long. The slope of the front end of the electro tome head is linear, the contact area with a tissue is increased compared with that of the traditional electrotome, and the electrocoagulation effect is enhanced; precise point-like coagulation is more easily finished by the acute angle front end of the electrotome nose, and the precise and accurate hemostasis demands of the thyroid surgery are met; the high-resistance and high-temperature resistant ZrO2 material is coated at the exposed part in the middle of the electrotome head, so the unnecessary electric burn of the contacted peripheral tissue caused by the middle position of the electro tome head is avoided.

Description

technical field [0001] The invention relates to a surgical electric knife commonly used in medical operations, in particular to a special electric knife head for thyroid and neck surgery. Background technique [0002] Surgical electric knife is the most commonly used medical device in surgery. The head of the traditional surgical electric knife is arc-shaped. During the operation, the head of the electric knife is in arc-shaped contact with the surgical cut surface. In addition to cutting the surface tissue, it is easy to damage the important deep tissue during cutting. Neck surgery is also prone to damage to important nerves. At present, the incidence of thyroid disease is increasing year by year, and there are so many patients who need surgical treatment, the demand for specialized and refined surgical instruments is very urgent. Neck surgery, especially thyroid surgery, has small incisions and a relatively small operating space. Accurate hemostasis at the bleeding point ...

AI Technical Summary

Problems solved by technology

Due to the curved shape of the traditional electric knife head, the middle part of the electric knife head is a stainless steel conductive structure, which makes the middle part of the electric knife head easy to contact with the surrounding tissue, and the electric burns the surrounding structure

Unable to complete precise hemostasis
