Abstract

The utility model discloses an adjustable position-limited operating knife with a double-face edge, which is composed of a knife blade 1 and a knife handle 2. The utility model is characterized in that the knife blade 1 is in a structure of the double-face edge, and is fixed to one side of the lower side of the knife handle 2 by using screws 3; the other side is provided with a sliding limited wheel 4; the knife blade 1 is also provided with a safe plastic knife sheath 5. The adjustable limited operating knife with a double-face edge not only has the advantages that the depth is adjustable, the incision depth is easy to control, and the phenomenon of the deflective and askew incision because of the dithering of hands is avoided, but also has the advantages of time saving and safety for replacing the knife blade.

Description

Double-sided blade adjustable limiting scalpel

Technical field

This utility model relates to a kind of improvement of scalpel, and tool fallow land a kind of double-sided blade adjustable limiting scalpel of saying so is applicable to the patient skin otomy.

Technical background

When surgical operation is cut skin at present, the scalpel that uses generally is made up of blade and handle of a knife, blade has the branch of round end, tip, blade must be installed on the handle of a knife during use, when skin was cut in operation, operating doctor can be held handle of a knife and directly cut skin, this dermatotomy, though existing extensive use also has weak point: the one, notch depth is difficult to control, crosses and can injure its hetero-organization deeply; The 2nd, the operating doctor that has is in cutting the skin process, and hands easily produces shake, causes otch not straight, occurs askewly partially, influences suture quality; The 3rd, existing blade divide again round end, point first two, use that to change blade both time-consuming, easily hinder finger again, very dangerous.

Summary of the invention

The purpose of this utility model is to provide a kind of depth-adjustment, controls notch depth easily, avoids that otch to occur askew partially because of hands shake, changes that blade saves time, the double-sided blade adjustable limiting scalpel of safety.

For reaching above purpose, technical solution adopted in the utility model is: this double-sided blade adjustable limiting scalpel, constitute by blade and handle of a knife, it is characterized in that blade is a double-sided blade, and be screwed a side below handle of a knife, opposite side is established the slip position-limited wheel, also is provided with safe plastics sheath on blade.This utility model is also implemented by following measure: described blade simultaneously be the semicircular arc sword, and one side is the triangle sword, between the two-edged and be provided with scale, for ease of the replacing blade, is provided with the open type sliding tray in the middle and upper part of blade; Described slip position-limited wheel is made of wheel body, bearing pin, establishes screw thread at an end of bearing pin, after bearing pin is installed wheel body, is screwed into screw thread in the screw of handle of a knife.When using this utility model, operating doctor takes off sheath earlier, according to the operative site skin thickness, the position-limited wheel wheel body diameter horizontal level that the required scale of blade transferred to and slide is tightened screw, then behind slip position-limited wheel wheel body contact skin, it promptly is notch depth, the position-limited wheel that slides this moment works, and slides on skin along cut line one side, avoids the askew partially phenomenon that does not directly produce because of hands shake otch.

The beneficial effects of the utility model are: compare with the scalpel of present use, not only have depth-adjustment, control notch depth easily, avoid the askew partially advantage of otch occurring because of hands shake, but also have when changing blade save time, safe advantage.
