CN2822661Y - Adjustable sleeve needle type medical device for sucking/injecting liquid - Google Patents

Abstract

The utility model relates to an adjustable sleeve needle type medical device for sucking/injecting liquid. The utility model is characterized in that a central tube is tightly fixed on a positioning frame, and a positioning ring is installed on the positioning frame and is locked or loosened by a nut; a hose is connected with the positioning frame and a central tube syringe, an outer needle tube and a plug are tightly fixed on a needle cylinder which is printed with scales, the position of the central tube in the outer needle tube can be controlled, and thus pus can be diluted and sucked out conveniently; the plug forms a sliding fit with the central tube, a hoop is tightly matched with the needle cylinder and the hose is connected with the needle cylinder and a syringe of the outer needle tube. When the central tube syringe is pushed, the antiphlogistic liquid is injected to dilute the pus and the pus is sucked out when the syringe of the outer needle tube is pulled. The device is mainly used for diluting and sucking out pus in cysts, ethmoidal cellules and deep wounds, the curative effect of diminishing inflammation is achieved and the minimally invasive treatment is implemented.

Description

Adjustable trocar liquid is annotated and is inhaled medical treatment device

Affiliated technical field

This utility model relates to a kind of adjustable trocar liquid and annotates the suction medical treatment device, especially can carry out the device that can also carry out the pus sucking-off when antiinflammatory liquid injects a position to the affected part.

Background technology

Existing liquid injects, the sucking-off form, generally adopts two pins to puncture at diverse location, and inconvenient operation is if the affected part position is less, just not easy to operate with two pins.

Summary of the invention

The novel task of this use is will provide a kind of adjustable trocar liquid to annotate to inhale medical treatment device, and it has a position puncture by regulating the optimum efficiency that the central canal position reaches liquid injection, pus sucking-off.It is mainly used in cyst, sieve hole, the dilution than the gash pus, sucking-off, reaches the effect of anti-inflammatory treatment, and that device also has is simple in structure, volume is little, be convenient to characteristic such as operation.

The novel task of this use is finished as follows, and a part adds enough injection before needing puncture for treating in the central canal syringe, pushes away syringe the central canal air is discharged; Add a small amount of injection outside in the syringe, push away syringe outer needle tubing air is discharged, can puncture affected part, after putting in place, can push away centring ring as required, make central canal reach, can find out the length (so that the dilution of pus, sucking-off) of feeding, jam nut then by scale, use the adhesive tape fixture, just can push away the central canal syringe, liquid is injected, draw outer syringe, make the pus sucking-off, finish therapeutic process.

The beneficial effects of the utility model are, can replace some operation, implement minimally-invasive treatment, alleviate the patient suffering, save medical expense.
