Description

The microneedle cutter

This utility model relates to a kind of orthopedics department scalpel, especially is suitable for the microneedle cutter of loosening and cutting off pathological tissue.

In technique known, the small needle knife that the orthopedics department treatment is used is made up of handle of a knife, needle body, pin cutter etc., and the pin cutter is made flat bladed.In the process of carrying out treatment of arthritis, hyperosteogeny diseases, pathological tissue or tension force fibrous tissue can be loosened and cut off to small needle knife, cures Bone injury disease.But, the pin blade type of this small needle knife has only a kind of flat sword type, during operation, the pathological tissue in deep can't be loosened and cut off to this cutter, can not complete penetrating tissue, lower intraosseous pressure, in addition, handle of a knife and needle body junction excessively section are short, stress concentration ruptures during use easily, can not satisfy the needs of clinical treatment.

In order to overcome the deficiency that existing small needle knife could be loosened and cut off the pathological tissue in deep and the fracture of handle of a knife and needle body place is taken place easily, this utility model provides a kind of microneedle cutter, the pin cutter has five kinds of difformities, become one group of microneedle cutter, not only microneedle cutter bulk strength, stiffness are good, can loosen and cut off the pathological tissue in deep, and scar tissue that can also loosen adhesion, microcirculation improvement.

The technical scheme that its technical problem that solves this utility model adopts is: the microneedle cutter is made up of handle of a knife, needle body, pin cutter, the indication of pin cutter direction etc., the pin cutter has five kinds of difformities, divide flat blade shape, oblique blade shape, three-blade shape, sickleshaped and wooden fork shape, become one group of microneedle cutter.Microneedle cutter integral body is made by medical stainless steel, and it is cone-shaped that needle body is, and the handle of a knife tail end is carved with cue mark.The handle of a knife of eight angulars is stressed evenly, and the indication of the pin cutter direction of handle of a knife tail end makes operator understand the blade direction of microneedle cutter all the time.The closed pathological tissue of getting involved, loosen and cutting off the deep of pin cutter energy; The scar tissue of loosen adhesion correctly; The Bone injury disease of difform pin cutter treatment different parts, different pathological form.

The beneficial effects of the utility model are that the closed pathological tissue of getting involved, loosen and cutting off the deep of pin cutter energy can penetratingly be organized, and lowers joint synovial bursa intraosseous pressure, microcirculation improvement.One group of five kinds of difform microneedle cutter can be treated multiple Bone injury diseases such as cervical vertebra inflammation, scapulohumeral periarthritis, breast lumbar vertebra matter hypertrophy, sciatica.Easy and simple to handle, frangibility not.

Below in conjunction with accompanying drawing this utility model is further specified.

Fig. 1 is the critical piece structure chart of microneedle cutter;

Fig. 2 is five kinds of difform pin cutter diagrammatic sketch of microneedle cutter.

The pin cutter 1 needle body 2 handle of a knifes 3 name labels 4 parallel edges of a knife indicate the 5 tapered edges of a knife to indicate 6 sickleshaped pin cuttves, 7 three-blade shape pin cuttves, 8 flat blade shape pin cuttves, 9 oblique blade shape pin cuttves, 10 wooden fork shape pin cuttves 11 among the figure

In Fig. 1, the microneedle cutter indicates 5 tapered edges of a knife indication 6 etc. to form by pin cutter 1, needle body 2, handle of a knife 3, name label 4, the parallel edge of a knife.Microneedle cutter integral body is made by medical stainless steel, and needle body 2 is cone-shaped, and big small end is excessively level and smooth, and small end is a pin cutter 1, and big end is a handle of a knife 3.Handle of a knife 3 is eight angulars, and except that rib middle part bright finish is carved with the name label 4, all the other all roll on the straight line decorative pattern, and it is parallel with the edge of a knife that the handle of a knife tail end is carved with parallel lines, and it is parallel with the tapered edge of a knife to be carved with acute angle.Microneedle cutter shown in Figure 2 has five kinds of difformities, divides sickle shaped 7, three bladeds 8, flat bladed 9, oblique bladed 10 and wooden fork shape 11, becomes one group of microneedle cutter.Difference requirement and bright finish according to operation are carved with name label, select the microneedle cutter for use, hold with a firm grip the handle of a knife of eight angulars, observe the indication of handle of a knife tail end pin cutter edge of a knife direction, all the time confirm the blade direction of microneedle cutter, in conjunction with diagnosis experience and treatment standard, carry out the Bone injury disease operation of different parts, different pathological form.
