Description

Take repeatable electric knife pen of interchangeable protective structure

Technical Field

The utility model relates to the field of medical equipment, in particular to a repeatable electric knife pen with a replaceable protection structure.

Background

The surgical pencil is an electrosurgical instrument for cutting tissue instead of a mechanical scalpel. 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. In surgery, high frequency pencil knives are often used. High frequency electric stylets with high frequency and high voltage current cut and coagulate tissue with high impedance, resulting in vaporization or coagulation of the tissue. Wherein, the electric knife pen point can be attached with partial eschar, and blood dirt can be contacted with the electric knife pen. The doctor needs to clean the pencil head of the electric knife or replace the pencil to continue the operation, which seriously affects the operation progress.

Chinese patent CN112089488A discloses an electric knife for breast cancer surgery, comprising a knife handle and a wire, wherein the wire is positioned in the middle of the knife handle, knife sleeves are arranged at two ends of the knife handle, and knife heads are arranged at the ends of the knife sleeves. The tool bit is connected with fixed threaded rod through the pivot, and the dead lever distal end is equipped with the mounting groove, has the movable rod in the mounting groove, is connected with the spring between the inner wall of movable rod and mounting groove. When the device is used, the sleeve is enabled to realize quick switching of the cutter heads on different cutter heads by rotating the rotary rod, so that the working efficiency is improved and the neatness is maintained. But can not replace the tool bit when using, and waste time and energy inconvenient fixed tool bit for availability factor has reduced.

Chinese patent CN218128726U discloses a disposable scab removing electric knife pen, including the electric knife pen body, the sliding hole has been seted up respectively to the both sides of the outside one end of electric knife pen body, be equipped with the scab brush on the inside fixedly connected with cleaning mechanism of electric knife pen body. During use of the pencil, the scab brush may be used to clean the blade head when eschar occurs at the head of the pencil. However, cleaning in the middle of the operation delays the operation process, reduces the operation efficiency, and does not completely remove eschar, so that the electric knife pen is not used as a new electric knife pen.

Detailed Description

The present utility model will be described in detail with reference to the accompanying drawings, but the protection of the present utility model is not limited to the following:

referring to fig. 1-5, a repeatable electric knife pen with a replaceable protection structure is provided, wherein a main body is the electric knife pen, a replaceable knife head is arranged at the front end of the electric knife pen, and a cable is arranged at the tail end of the electric knife pen; the outer surface of the electric knife pen is coated with a protective structure 1 which can be separated from the electric knife pen; the protective structure 1 is internally provided with a cavity for accommodating the electric knife pen, and when the electric knife pen is placed in the cavity, the electric knife pen can be isolated from the external environment. Wherein, the protection structure 1 can establish sterile barrier to prevent blood dirt from entering the electric knife pen, and the protection structure 1 does not need to be cleaned and directly uses as disposable consumable. The replaceable tool bit can be provided with different specifications for use, can be used for rapidly replacing the replaceable tool bit with different specifications in the operation process for operation, can be used as disposable consumable, and can be reused after disinfection and cleaning are finished after use. The protection structure 1 can also be applied to other types of electric knife pens, and is not limited to common monopole electric knife pens; e.g. a doctor blade pencil, a pencil of LEEP knife; the protective structure 1 is preferably in the shape of an electrotome pen, but can also be correspondingly adjusted due to ergonomics, and the size, shape and size can be changed.
