Summary of the invention

In sum, the purpose of this utility model mainly is the problem big to patient's limb injury during the tenosynovitis of the traditional narrow property of treatment of solution is performed the operation, and proposes a kind of de Quervain's disease small needle knife.

For realizing that the technical scheme that the purpose of this utility model adopts is: the de Quervain's disease small needle knife comprises needle body and cutter hub; Described needle body is a tubular body, and its front end is an arcual shank portion, and tail end is a needle handle portion; Described cutter hub comprises knife bar and is connected to cutter leaf and handle of a knife on knife bar front end and the tail end, wherein, described knife bar has identical radian with shank portion, knife bar interts in the tube chamber of needle body, described cutter leaf is the sidewall of a vertical knife bar and the cutter blade that has blade, and cutter leaf width is greater than the lumen diameter of knife bar diameter less than needle body.

Include as the technical scheme that this utility model is further improved:

Also comprise the arc pin heart that can place the tube chamber of needle body.

Also comprise an arc probe that can place the tube chamber of needle body.

The tail end of described needle handle portion is provided with a needle-blocking mouth longitudinally; Described handle of a knife is a thallus that can be stuck in the needle-blocking mouth; The tail end of the described pin heart also is provided with a pin heart handle that can be stuck in the thallus shape in the needle-blocking mouth.

When described pin heart handle was stuck in the needle-blocking mouth, the needle point of the described pin heart just protruded the front opening that places needle body.

The front opening of described needle body is curved tangent plane.

The beneficial effects of the utility model are: this utility model has changed traditional operation and has cut with the anatomical layer layering and expose pathological tissues and undergo surgery and cut the method that narrow stndon sheath reaches therapeutic purposes, this utility model is with used surgical instrument in the designed tenosynovitis operation that is used for the treatment of narrow property of another new knowledge of anatomical features, behind needle body transdermal arrival stndon sheath nearside, inserting cutter hub again from the inner chamber of needle body cuts narrow stndon sheath, thereby reach the purpose of treatment, this utility model has reduced damage and the mental pressure of traditional surgical approaches to patient's body, numerous and diverse program of simple original operation.
