Abstract
The invention discloses a scar subcutaneous releasing knife which comprises a handheld handle and a knife handle connected to the handheld handle. The tail end of the knife handle is connected with a knife body, and the included angle formed by the plane where a cutting edge of the knife body is located and the axis of the knife handle is alpha. According to the scar subcutaneous releasing knife, the design that the included angle formed by the plane where the cutting edge of the knife body is located and the axis of the knife handle is 120 degrees is adopted, when a scar releasing operation is conducted, stripping of the scar releasing knife most saves labor, the consistency of a stripping plane is the highest, the injury to normal tissue is the minimum, meanwhile, scar releasing can be conducted with only a small incision, the knife body of the scar releasing knife is made of titanium alloy materials of surgical knife blades, and therefore the scar subcutaneous releasing knife has good hardness and sharpness and can evenly and fast conduct scar releasing.
Description
Technical field
The present invention relates to medical operation device, be specifically related to a kind of for the subcutaneous scalpel of loosening of cicatrix.
Background technology
Cicatrix is one of very common disease of skin surgery and plastic surgery.Along with growth in the living standard, people improve day by day to treatment hope and the therapeutic effect of cicatrix.The Therapeutic Method of cicatrix is capable a variety of at present, comprises excision, filling, laser therapy, medicine etc.Depressed scar usually has obvious adhesion with subcutaneous tissue, the therefore Therapeutic Method DeGrain of medicine, laser, and excision wound is larger, and postoperative have a new cicatrization; Adopt the method for filling to treat, need to carry out that sufficient cicatrix is subcutaneous loosens, mainly at present adopt that shears is subcutaneous loosens and syringe needle repeatedly stabs and loosens.And all there is obvious shortcoming in these two kinds of methods: 1. shears subcutaneous loosen need to be larger otch just can carry out, therefore can cause significantly new cicatrix; Syringe needle repeatedly stamp can cause loosening inhomogeneous and incomplete, thereby impact fill effect.
Summary of the invention
The object of the present invention is to provide a kind ofly for the subcutaneous Minimally Invasive Surgery cutter of loosening of cicatrix, solve shears in above-mentioned large otch and the puncture needle problem of non-uniform of loosening of loosening, reach Wicresoft and the object of evenly loosening.
Object of the present invention is achieved through the following technical solutions: the subcutaneous Debonding knife of a kind of cicatrix, and comprise hand holding handle and be connected to the handle of a knife on hand holding handle, be connected with cutter hub at the end of handle of a knife, the axis of its cutting edge of described cutter hub plane of living in and handle of a knife forms angle α.
Optimum, described angle α is 120 °; By repeatedly repetition test of user, only have when the axis of its cutting edge of cutter hub plane of living in and handle of a knife forms angle and form 120 °, while carrying out cicatrix absent-mindedness operation, it peels off the most laborsaving, peels off plane concordance the highest, and normal tissue damage is minimum.
Cutter hub of the present invention can design like this: described cutter hub is arc sickle shaped, and inner side has cutting edge, adopts this kind of design, coordinate the angle of 120 ° to peel off operation, realize otch little, absent-mindedness good evenness, absent-mindedness can not become the object of significantly new cicatrix completely.
Cutter hub of the present invention can also have following several design:
Described cutter hub both sides have cutting edge, and cutter hub narrows gradually and forms endways top tip part along free end.
Described cutter hub outer has cutting edge, and cutter hub narrows gradually and forms endways circular arc end along free end.
Described cutter hub is the flat bladed that outer has cutting edge.
Described cutter hub is lance shape, and both sides, buck knife body one end have cutting edge.
In the present invention, optimum design is that described hand holding handle length accounts for 2/3 of whole scalpel length, and under this length, executing patient, to hold cutter comfort level better, executes art more convenient laborsaving.
Described handle of a knife and cutter hub are the integrative-structure that titanium alloy is made, and make it have good hardness and sharpness, all even Adhesion releases that carries out fast.
On described hand holding handle, be also provided with anti-skid structure, this anti-skid structure can be also some anti-slip veins for some salient points.
The present invention compared with prior art, there is following advantage and beneficial effect: adopt its cutting edge of cutter hub plane of living in to form angle with the axis of handle of a knife and become the design of 120 °, while carrying out cicatrix absent-mindedness operation, it peels off the most laborsaving, peel off plane concordance the highest, normal tissue damage is minimum.Only need a very little otch can carry out Adhesion release simultaneously, and the titanium alloy material of its cutter hub employing knife blade, good hardness and sharpness therefore there is, all even Adhesion releases that carries out fast.
