When in a surgery, the novel small needle knife shovels and strips, horizontally strips, longitudinally strips and the like in the deep, thereby obviously reducing the pain of a patient in the surgery, basically ensuring not to damage the non-lesion tissue around, affectively preventing from being damaged or cutting off the ligament, the tendon and the like, not only ensuring the therapical effect but also avoiding the discomfort of the patient after the surgery, is applicable to soft tissue injury lesion and bone and joint lesion surgeries, has simple structure and low prices, and is worthy of wide popularization.

Description

Novel small needle knife

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of novel small needle knife.

Background technology

The small needle knife therapy is a kind of closure lysis between operation method and non-operative treatment, and its indication mainly is that the soft tissue injury sexually transmitted disease (STD) becomes and osteoarthrosis.Because the small needle knife therapy is to operate treatment under non-direct-view, if to human dissection particularly topography be unfamiliar with, maneuver is improper, cause damage easily, when carrying out method strip operation such as pinch spalling, horizontal stripping, vertical stripping in the deep, maneuver is suitable light, not so can aggravate the pain, even the non-pathological tissues tissue around the damage.Do at joint and vertically to cut when stripping, easily damage or cut off ligament, tendon etc.

The utility model content

For overcoming above-mentioned defective, the utility model discloses a kind of novel small needle knife, by changing pin knife-edge shape, alleviate patient's pain in the operation, and improved the sense of discomfort of patient's postoperative.

The technical scheme that this utility model adopted is a kind of novel small needle knife, comprises handle, the needle body, pin cutter three parts, and pin cutter width generally equates with diameter of needle body, cutting edge is sharp, and the point of a knife angle is an acute angle, and pin cutter blade is not a straight line, be the setback line, the angle of setback line is the obtuse angle.

Described point of a knife angle is 30 °, and blade setback wire clamp angle is 169 °.

The beneficial effects of the utility model are in the operation, are difficult for causing damage.When carrying out method strip operation such as pinch spalling, horizontal stripping, vertical stripping in the deep, obviously alleviate pain in patient's art, basic assurance does not damage non-pathological tissues tissue on every side.Do at joint and vertically to cut when stripping, long plantar ligament and plantar aponeurosis that mediation is nervous are effectively avoided damage or are cut off ligament, tendon etc.Both guarantee curative effect, removed the discomfort of postoperative patient again from.
