Description

Portable two-purpose, which is chosen, controls pin

Technical field

The utility model belongs to technical field of medical instruments, and in particular to a kind of portable two-purpose, which is chosen, controls pin.

Background technology

Pricking therapy is on the skin at the certain position of patient, and skin is broken with three-edged needle, round-sharp needle, injection injection needle Lower white fiber sample thing, it is a kind of traditional remedies of the traditional Chinese medical science to treat the method for disease.It is usually used in hemorrhoid, anal fissure, hyperthyroidism, urgency The illnesss such as membranous conjunctivitis, sty, acne.

At present, medical worker operate when, be to be operated using common injection needle mostly, if skin choose mouth it is shorter if Fine with injection needle, and longer if choosing mouth, then injection needle uses more difficult, need to change and longer choose pin.And And the existing syringe needle for choosing pin instrument is typically all exposed in the external world, is easily infected by extraneous miscellaneous bacteria.

The content of the invention

The utility model needs according to circumstances to change syringe needle and pin in use in order to solve to choose pin in the prior art The problem of exposed, there is provided a kind of portable two-purpose, which is chosen, controls pin.

A kind of portable two-purpose, which is chosen, controls pin, including hollow handle, connector and needle body, one end of the hollow handle are provided with Shi pins, the other end are provided with internal thread, and the both ends of connector are respectively equipped with the external screw thread matched with the internal thread of hollow handle, needle body One end insertion connector.

The top of Suo Shu Shi pins is rounded nose.

The material of the hollow handle, connector and needle body is copper or stainless steel.

During without using needle body, the insertion hollow handle of needle body, pass through the external screw thread of connector and the internal thread of hollow handle Connection, during using needle body, connector is turned on, is overturn, makes needle body outside, by the external screw thread of the connector other end and hollow Handle connects.

Hollow handle one end Shi pins can be both used as and skin surface was passed through again as the prolongation of hollow handle The instrument of network pressing.

The beneficial effects of the utility model are as follows：

1. the utility model can protect needle body not infected or damage；

It is 2. easy to carry；

3. Shi pins can extend handle as a part for handle, easy to operate, can be used as to press channels and collaterals again.
