Description

Medical electric surgical knife

Technical Field

The utility model relates to the field of surgical instruments, in particular to a medical surgical electrotome.

Background

The surgical instruments refer to medical instruments used in clinical surgery, and include scalpels, scissors, forceps, retractors, suture needles, and the like. With the continued development of the medical technology, more and more advanced surgical instruments are being used in clinical surgery.

Medical scalpels are advanced electrosurgical instruments that replace mechanical scalpels for tissue cutting. The tissue is heated when the high-frequency high-voltage current generated by the tip of the effective electrode contacts with the body, so that the separation and solidification of the body tissue are realized, and the purposes of cutting and hemostasis are achieved. The high-frequency electrotome is widely applied to all levels of operations at present, and has the functions of electrocoagulation and electrotome, so that bleeding can be reduced while tissues are effectively cut, a good operation field is provided, the operation efficiency is greatly improved, the damage is small, and the high-frequency electrotome is popular in various surgical departments.

Most of the common electric knives are straight knife heads, and have good effect when being applied to excision of face and neck parts. However, for submucosal tumor of tonsils and pharynx, the straight knife head is often unable to meet the needs of the surgeon because of its fixed angle, and the straight knife head easily blocks the doctor's view. Most of the bending cutter heads are needle-shaped, and the cutting and hemostasis effects are limited, so that the bending cutter heads can only be used for treating special diseases of the oral cavity and eyes. Therefore, for a narrow surgical field such as tonsils and pharynx, a doctor can often only perform surgery by using a conventional mechanical blade, and bleeding risk is high and surgery time is long by using the conventional mechanical blade.
