Abstract

The utility model discloses a combined visible cambered surface touching skin positioning skin cutting device, which consists of an oblate tool shank (1), a blade (2) and a semicircular plate-shaped positioning body (3). The cutting device is characterized in that the blade (2) is inserted into the oblate holes of the semicircular plate-shaped positioning body (3) and the oblate tool shank (1); the blade is pushed out by a push handle (11), and is fixed by a bolt (4). The front wall of the oblate tool shank (1) is provided with depth setting calibration (10). The sidewall of the semicircular plate-shaped positioning body (3) is provided with an LED light source (14). As the combined visible cambered surface touching skin positioning skin cutting device adopts the cambered surface of the semicircular plate-shaped positioning body to contact the surface of skin, fingers do not contact skin, and the cutting depth is predetermined; therefore, the cutting depth can be adjusted and fixed conveniently, the cutting is not displaced or skew easily, two lips of the incision are symmetrical, and the incision can be sewn easily. As the small illumination devices are arranged on the two sides of a knifepoint part, at the state of no spatial occupancy, the two sides of the blade do not have shadows; the surgery line of sight facilitates observation, thereby being good for improving surgery quality.

Description

Make up visual cambered surface and touch skin location dermatotome

Technical field

This utility model relates to a kind of medical surgical instrument, and specifically a kind of visual cambered surface of combination when being applicable to the operation of department of general surgery incision of skin is touched skin location dermatotome.

Background technology

At present, perform an operation when cutting skin, cut skin with scalpel always in department of general surgery, this scalpel is made of blade, handle of a knife, and when skin was cut in operation, the patient held handle of a knife armrest method skill and directly cuts skin, its weak point: the one, notch depth is difficult to adjust, and the depth is difficult for the location; The 2nd, armrest refers to touch cutaneous branch support when cutting skin, holds the cutter hands and often produces shake, causes the edge of a knife not to be straight line, occurs askewly partially, influences suture quality; The 3rd, blade and handle of a knife be for fixedlying connected, and is not easy to sterilization and cleans; The 4th, can produce shade at the shady face of blade and handle of a knife, but the influence apparent resolution.

Summary of the invention

The purpose of this utility model be to provide a kind of not only depth-adjustment, easily control notch depth, avoid that otch to occur askew partially because of hands shake, but also the visual cambered surface of combination that shady face can not produce shade when being convenient to dismounting sterilization, operation is touched skin location dermatotome.

For reaching above purpose, the technical scheme that this utility model adopted is: this makes up visual cambered surface and touches skin location dermatotome, by flat body handle of a knife, blade, semicircle plate-like positioning body constitutes, connection-peg is established on top at semicircle plate-like positioning body, the flat mouthful of internal fixation that connection-peg inserts flat body handle of a knife lower end connects, it is characterized in that establishing the blade head in semicircle plate-like positioning body inserts flat hole, in flat body handle of a knife, establish the blade shank and insert flat hole, the blade head of the tip of blade in semicircle plate-like positioning body inserts the flat hole and stretches out, and be screwed, blade is a triangular edges, establish guide chute along blade shank centrage, screw screws in the guide chute of blade shank in the screw that inserts flat hole perpendicular to the blade head, when the blade tip stretch out the length of semicircle plate-like positioning body selected after, tighten screw, blade is fixed, on the front side wall of flat body handle of a knife, establish axial slide opening, the pushing handle of blade shank upper end stretches out from axial slide opening, on the edge of axial slide opening, be provided with the depthkeeping scale, promotion adjustment by pushing handle, the length that stretch out at the adjustable blade tip, lower sidewall at semicircle plate-like positioning body is established circular pocket, establish led light source in circular pocket, half of led light source exposes.This utility model is also implemented by following measure: battery case is established in the upper end in flat body handle of a knife, led light source is connected with battery case by lead, on and off switch is located on the sidewall on flat body handle of a knife top, makes two sides of blade tip can shade not occur because of having set up semicircle plate-like positioning body by lighting led light source; Flat body handle of a knife, blade, semicircle plate-like positioning body are stainless steel material and make.When using this utility model,, determine the point of a knife exposed length, tighten screw then, can determine that blade cuts the skin degree of depth, turn on the power switch and get final product operation technique by the adjusting of pushing handle according to the operative site skin thickness.

The beneficial effects of the utility model are: compare with the skin scalpel of cutting of present use, owing to adopted the cambered surface of semicircle plate-like positioning body to touch skin surface, the reuse finger does not touch skin, cutting-in is fixing in advance, so it is fixing that cutting-in is convenient to adjust, tangent line is difficult for askew partially, and the edge of a knife two lips are easy to sew up symmetrically; Owing to increased small illuminator in the nose part both sides, so under situation about not taking up space, make the equal shadow-free in blade both sides, the operation sight line is convenient to observe, and can be beneficial to and improve the operation quality.
