Multi-side operation electric knife head

Abstract

The invention discloses a multiple-surface operation electrotome tool bit. The front end of the tool bet is coated with an anti-sticking conductive perfluoro caprylic acid material; the middle of the tool bit exposed outside a tool shank is coated with an insulating high-temperature resistant perfluoro caprylic acid material; the upper edge and the lower edge of the front end of the tool bit are parallel with each other; the upper edge and a beveled edge form an angle of between 45 and 60 degrees; the intersection part of the edges is cambered; all the margins of the upper edge, the lower edge and the beveled edge are chamber angles; the length of the beveled edge is between 2 and 4 millimeters; and the length of the lower edge is between 2 and 3 millimeters. The beveled edge of the frontend of the multiple-surface operation electrotome tool bit and a cutting plane just form surface-to-surface contact, thus the problems that the cutting depth in a tissue is hard to control and deep part important tissues of a cut surface are easy injure accidentally because of cutting on different planes in the cutting process; more importantly, the surface can play a role in separating passivityand scrapping. The surface on the lower edge of the front end of the tool bit can also cut the tissues on an electric coagulation lateral surface to form use functions of a plurality of surfaces.

Description

technical field [0001] The invention relates to a surgical electric knife commonly used in medical operations, in particular to a multi-faceted surgical electric knife head. Background technique [0002] Surgical scalpels are one of the most commonly used medical devices for surgeons to perform operations. Surgical operation doctors know in surgical practice that when the general operator holds the knife, the entire electric knife forms an angle of about 45-60 degrees with the cutting plane, while the traditional knife head forms a point between the knife head and the tissue when it is used. In this way, the depth of the tissue to be cut is not well grasped during operation, and it is easy to accidentally injure important tissues deep in the cutting surface by not cutting on the same plane, such as easy to accidentally injure blood vessels and bile ducts during bone surgery. The head of the traditional electric knife is made of stainless steel. During cutting, especially du...
