Abstract

The utility model relates to a surgical instrument for curing tenosynovitis, in particular to a scalpel blade for curing tenosynovitis. The scalpel blade comprises a blade main body which presents a flat shape; a blade head connected with the front end of the blade main body presents has an arc structure; the front end face of the blade head is formed by a straight line and two arc lines; the intersecting line of the two camber lines composes the blade edge; an included angle is formed between the blade edge and the upper plane of the blade main body; and the blade edge is parallel to the normal line of the upper plane. Compared with the prior art, the scalpel blade adopting the technical scheme has the advantages of simple structure, convenient manufacture, small tissue damage and safe operation.

Description

The knife blade of treatment tenosynovitis

Technical field:

This utility model relates to a kind of operating theater instruments for the treatment of tenosynovitis, a kind of specifically knife blade for the treatment of tenosynovitis.

Background technology:

Tenosynovitis is clinical comparatively common, can adopt Therapeutic Method such as sealing and massaging and physiotherapeutical in early days.Need operative treatment when expectant treatment is invalid, operation and needle knife therapy all might injured nerve or its hetero-organizations.

The utility model content:

Goal of the invention of the present utility model is to overcome the deficiency of background technology and provides a kind of making simple, the knife blade of easy to operate treatment tenosynovitis.

This utility model adopts following technical scheme:

A kind of knife blade for the treatment of tenosynovitis, comprise vane body, described vane body is flat, its whole curved structure of the cutter head that is connected with the vane body front end, the front end face of this cutter head is made of straight line and two camber lines, the intersection of these two camber lines constitutes blade, is provided with angle between the last plane of this blade and vane body, and this blade parallels with last planar normal.

This utility model that adopts technique scheme compared with prior art, have simple in structure, easy to make, damage little, the advantage of handling safety.

As a kind of optimal way of the present utility model, described two camber lines are symmetrical arranged, and described blade and last planar normal coincide.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the side view of Fig. 1.

Fig. 3 is that the A of Fig. 1 is to view.

The specific embodiment:

Below in conjunction with drawings and Examples in detail this utility model is described in detail:

A kind of knife blade for the treatment of tenosynovitis is referring to accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, among the figure: vane body 1, cutter head 2, front end face 3, installing hole 4, blade 5, angle 6, straight line 7, the first camber lines 8, the second camber lines 9, last plane 10.

Vane body 1 is flat in the present embodiment, cutter head 2 its whole curved structures that are connected with vane body 1 front end, the front end face of cutter head 2 is made of straight line 7 and two camber lines, article two, camber line is respectively first camber line 8 and second camber line 9, the intersection of first camber line 8 and second camber line 9 constitutes blade 5, be provided with angle 6 between the last plane 10 of blade 5 and vane body 1, angle 6 in the present embodiment is 25 °, blade 5 parallels with the normal on last plane 10, and the rear end of vane body 1 is provided with installing hole 4.

As a kind of optimal way of the present utility model, two camber lines in the present embodiment, promptly first camber line 8 and second camber line 9 are the symmetrical centre setting with the mid point of straight line 7, blade 5 and last plane 10 the normal setting that coincides, shown in accompanying drawing 3.

Certain fillet is suitably produced in front end face 3 its both sides in the present embodiment, is beneficial to the embedding otch.

Cut with ordinary blade earlier during the treatment tenosynovitis, the more common otch of otch is little, be separated to stndon sheath with mosquito forceps, cutter head 2 is close to stndon sheath pushes near-end to, blade 5 is towards stndon sheath, can feel after cutter head 2 is pushed into stndon sheath nearside edge has the step sense, is close to the key sheath then equally and lifts vane body 1 to returning, and narrow stndon sheath can be cut.
