Description

A kind of liquid-needle knife of controlling depth of cut

This utility model relates to medical apparatus, the specifically a kind of liquid-needle knife that can control depth of cut.

In today that science and technology is advanced by leaps and bounds, human had higher demand to health care, and any product has only continuous update, just has its indomitable vigorous vitality.It is unexceptional that the reform of same pin cutter cutter becomes, and it will be that pin cutter medical science forms and the important symbol that develops.The seriation of pin cutter, diversification, to specialize also will be the inexorable trend of pin cutter reform.

Liquid-needle knife resembles acupuncture therapy used " pin ", but end has the wide blade of 0.8-1mm.This cutter has certain stiffness and toughness, and is sharper, not turned so can cut or peel off pathological tissues in vivo, is particularly suitable for treating chronic soft tissue injuries.Liquid-needle knife is a hollow body, behind the arrival diseased region, can pumpback detect during treatment, and cutting is loosened, the injection related drugs, and injection of oxygen is stayed and is planted medicated line, is a kind of achieving many things at one stroke, the miniature closure new instruments of the pin hole that settles at one go.But the liquid-needle knife depth of needle of prior art is difficult for grasping, and mainly with doctor's experience, occurs the inserting needle error sometimes.Needle handle is easily slippage also, if overexert, fall through, may cause serious consequence.Prior art has improvement, perfect necessity.

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of liquid-needle knife of controlling depth of cut is provided, and can accurately grasp the degree of depth of feed under the situation of direct-view, improves therapeutic effect, avoids the inserting needle error, makes operation more firm, more accurate, safer.

The purpose of this utility model is achieved in that

A kind of liquid-needle knife of controlling depth of cut comprises needle body and needle handle, it is characterized in that:

On needle body, there is demonstration to thrust the graduation mark of the degree of depth;

Controller is housed on needle body, and this controller is cover shape, is set in the needle body cylindrical and can upper and lowerly moves, and the shift position locks with the tightening part.

Described controller is a metallic sheath, and its tightening part is a cross screw.

Described controller is an elasticity pincers, and its tightening part is a spring.

There is anti-skidding stricture of vagina on described needle handle surface.

Described needle body is a hollow pipe, and there is the socket that connects nook closing member and/or syringe its upper end.

The cutter head of described needle body can be flat sword type, any in oblate angle type, dog type, twolip cherry rifle type, Horse hoof dial type, the indwelling medicated line thimble tube.

This utility model has following positive beneficial effect:

1. be printed on scale mark on the needle body of this liquid-needle knife, clinical manipulation is unlikely to blindly, can accurately grasp the degree of depth of inserting needle under the situation of direct-view, and through sick institute during the treatment disease can injectable drug, and cutting is loosened, and injection of oxygen can be stayed again and plant medicated line.Accuracy is higher, simultaneously, is provided with the controller of the upper and lower slip of energy on the needle body, can accurately control the fixedly degree of depth of inserting needle.For example: need inserting needle 3cm safer at a certain position, so, we slide into the 3cm scale place of needle body to controller, and are fixing then, during the inserting needle cutter, avoid inserting needle to slip up like this, overexert, and fall through and cause serious consequence.

2. this liquid-needle knife handle is provided with anti-skidding stricture of vagina, pin cutter in the past, band sterile gloves during operation, be stained with disinfectant solution or medicinal liquid, easy slippage fell when hands was pinched the needle handle inserting needle, and anti-skidding stricture of vagina is arranged above the handle of a knife after the improvement, and the fastness of hand-held pin cutter is increased, dynamics when adding the large needle broadsword play, more firm when making it to operate, more accurate, safer.
