High-frequency electric knife tool bit capable of reducing adhesion

Abstract

The invention discloses a high-frequency electric knife tool bit capable of reducing adhesion. The high-frequency electric knife tool bit consists of a handle and blade, wherein the blade is provided with three rectangular hollow structures and a semicircular hollow structure; the three rectangular hollow structures are arranged in sequence from a position near the handle to the end part of the blade; the semicircular hollow structure is positioned on the end part of the blade; the blade surface is coated with a layer of zirconium dioxide coating. By adopting the hollow structures and coating treatment, tissue adhesion can be reduced effectively, and electric burning without adhesion is realized. During surgical operation, the tool bit does not produce harmful substances, is non-toxic and harmless, and has no effect on the health of operators and patients.

Description

technical field [0001] The invention relates to a novel high-frequency electric knife head for reducing tissue adhesion during minimally invasive surgery, and belongs to the technical field of minimally invasive medical devices and appliances. Background technique [0002] With the continuous innovation and development of medical technology, minimally invasive surgery technology is becoming more and more mature, and has gradually become a new trend of surgery. Since the cutting temperature is above 400°C during the operation, practice has proved that the living tissue cut by the high-frequency electric knife is prone to high-temperature burns, tissue cracking, and eschar carbonization, and then adheres to the surface of the blade, and the center of the knife head has the most serious adhesion. , which can even cause tissue tearing. In order to ensure the smooth progress of the operation, it is necessary to change the knife frequently or wipe off the adhered carbonized tissu...

Problems solved by technology

But this method has a limited scope of application, and the anti-adhesive effect is general

There is also a type of single coating treatment on the surface of the cutter head, typically coated with polytetrafluoroethylene (polytetrafluoroethylene is often used for non-stick pan coating), but during the operation, the cutter head coating is exposed to high temperature. Will volatilize harmful substances and pose a health threat to doctors and patients

All in all, traditional cutter heads are limited to varying degrees by poor effect, complex structure, high temperature release of toxic substances or high cost of the coating, so design a simple structure, obvious effect, non-toxic and harmless and low cost The high-frequency electric knife head is of great significance
