Abstract

The utility model relates to a structure of medical small needle scalpel, mainly the bottom of the needle scalpel handle is provided with a cavity and also is provided with a thread hole at the side, the thread hole is communicated each other with the cavity so that vertical shape is formed between the thread hole and the cavity, when needle body blade is inserted into the needle scalpel handle through the cavity, the fixing part resists against the needle body blade through thread hole so that the needle body blade is fixed with the needle scalpel handle each other so as to be advantageous for medical micro-invasive operation, when repeated application is required, the fixing part is turned loose and then the needle body blade is replaced so as to meet the requirement of health care and more meet the green design, the utility model is an environment-friendly and low cost operation device.

Description

The structure of medical small needle knife

Technical field

This utility model relates to a kind of structure of medical small needle knife, particularly about the structure of a kind of replaceable needle body blade with the medical small needle knife that meets health care and require.

Background technology

See also existing small needle knife schematic perspective view shown in Figure 1, it consists predominantly of needle body blade 2 and handle of a knife 1, this needle body blade 2 firmly links with the bottom of handle of a knife 1, it can be manipulated, because this small needle knife 3 is not to use aseptic packaging or deserted medical apparatus, make it before medical Minimally Invasive Surgery treatment, all need with needle body blade 2 and handle of a knife 1 thorough disinfection, to meet the requirement of health care; In addition, if small needle knife 3 then needs to grind again, to guarantee the sharpness of needle body blade 2 after reusing for several times again.

Though above-mentioned small needle knife 3 can reach the effect of medical treatment, it is still more numerous and diverse in using on the step, and does not meet health care and requirement cheaply.

Therefore, provide a kind of improved simple structure and easy to use, meet health care, medical small needle knife is real in necessary cheaply.

Summary of the invention

Main purpose of the present utility model is to provide a kind of replaceable needle body blade, to meet the structure of the medical small needle knife that health care requires.

A time purpose of the present utility model is the structure that is to provide a kind of simple structure and medical small needle knife easy to use.

Another purpose of the present utility model is to be to provide a kind of structure that can significantly reduce the medical small needle knife of manufacturing cost.

Can reach the structure of the medical small needle knife of above-mentioned utility model purpose, include pin handle of a knife, needle body blade and fixture, this pin handle of a knife is made by the material that can have an X-rayed, and be provided with hole in its bottom, side then is provided with screwed hole in addition, this screwed hole and hole run through mutually, make and be vertical configuration between screwed hole and hole, when needle body blade sees through hole insertion pin handle of a knife, fixture then rotates into by screwed hole and supports mutually with the upper limb of needle body blade, make needle body blade and pin handle of a knife interfix, be beneficial to the use of medical Minimally Invasive Surgery; When desire is reused, then fixture is unscrewed, and the discharge and change the needle body blade, by this to meet the requirement of health care, and because of needle body blade is a jettisonable, therefore no longer include the doubt of reusing communicate illness because of utensil, more conform with green design, environmental protection and meet economic benefit simultaneously.

The structure of medical small needle knife provided by the utility model when comparing mutually with other existing small needle knife, has more following advantage:

1. this utility model is the needle body blade that utilizes jettisonable, makes it no longer include the doubt of reusing communicate illness because of utensil.

2. this utility model is the needle body blade that utilizes jettisonable, makes it effectively solve surgical instrument when reusing, the problem that the sterilization of utensil and utensil blade sharpness grind.

3. firmly whether but this utility model is the pin handle of a knife that utilizes perspectivity, it can be known when the discharge and change the needle body blade see needle body blade and pin handle of a knife, to increase the safety in the use.

Description of drawings

Fig. 1 is the schematic perspective view of existing small needle knife;

Fig. 2 is the decomposing schematic representation of the structure of the medical small needle knife of this utility model;

Fig. 3 is the schematic perspective view of the structure of the medical small needle knife of this utility model.

Specific implementation method

See also Fig. 2 and shown in Figure 3, be the schematic perspective view of medical small needle knife provided by the utility model, mainly include pin handle of a knife 4, needle body blade 5 and fixture 6; The front end of this needle body blade 5 has blade, and it is cylindric that the rear end then is.

This pin handle of a knife 4 by perspectivity good and acidproof, alkali proof acryl made, and its bottom is provided with hole 41, and be provided with screwed hole 42 in addition in the side of pin handle of a knife 4, this screwed hole 42 runs through mutually with hole 41, make 41 of screwed hole 42 and holes be vertical configuration, when the needle body blade 5 of stainless steel system sees through hole 41 insertion pin handle of a

knifes

4,6 of fixtures can rotate into and support mutually with the upper limb of needle body blade 5 by screwed hole 42, make 4 on needle body blade 5 and pin handle of a knife interfix, be beneficial to the use of medical Minimally Invasive Surgery; When desire is reused, then fixture 6 is unscrewed, and discharge and change the needle body blade 5, by this meeting the requirement of health care, but and because of pin handle of a knife 4 be perspectivity, so in the process that needle body blade 5 is installed, firmly whether user can know to see needle body blade 5 and pin handle of a knife 4, increasing the safety on using, and because of needle body blade 5 be jettisonable, therefore no longer include the doubt of reusing communicate illness because of utensil, more conform with green design, environmental protection and meet economic benefit simultaneously.

Above-mentioned explanation only is specifying of this utility model specific embodiment, right persons skilled in the art can be understood, any unsubstantiality change or conversion all are included in this utility model scope, and this embodiment is not in order to limit claim of the present utility model.
