Abstract

The utility model relates to the technical field of medical devices, in particular to a thoracic closed drainage guide needle. The utility model aims at overcoming the shortcoming that the complicated closed drainage surgeries can be performed by surgeons for the treatment of pleural effusion and pneumatosis. The technical proposal includes a sleeve, a push rod and a needle, the utility model is characterized in that a guide tube which passes through and forms an acute angle with the sleeve is arranged on the sleeve which is arranged at one end of the push rod; the push rod is connected with the needle which is extended out of the sleeve, a cylindrical needle body of the needle is tightly combined with the inner diameter of the sleeve, and the two are matched by sliding. The utility model is applicable to the liquid discharge and gas exhaust treatments of pleural effusion caused by various diseases and various types of pneumothorax, and the utility model can inject the drug to the thoracic cavity through a drainage soft tube at any time.

Description

The closed drainage of pleural cavity guide needle

Relate to technical field:

This utility model relates to technical field of medical instruments, is specifically related to a kind of closed drainage of pleural cavity guide needle.

Background technology:

In the treatment at home and abroad at present to hydrothorax, pneumatosis, traditional closed drainage occupies than great share always, this method must be carried out complicated operative treatment by the surgeon, therefore used apparatus is many and be the routine operation apparatus, wound is big, untoward reaction or complication are many, and patient's hospital stays is long, and medical expense is big.Also there is not a kind of effective apparatus can be used for hydrothorax, pneumatosis are carried out drainage treatment at present.

Summary of the invention:

The purpose of this utility model provides a kind of closed drainage of pleural cavity guide needle, overcomes at present to being carried out the shortcoming of complicated closed drainage operation in the treatment of hydrothorax, pneumatosis by the surgeon.

To achieve these goals, technical solution of the present utility model is as follows: a kind of closed drainage of pleural cavity guide needle, comprise sleeve pipe 2, push rod 3 and syringe needle 1, its special character is: the sleeve pipe 2 of described push rod 3 one ends is provided with the guiding tube 4 that is acute angle, perforation with it; Described push rod 3 is connected with the syringe needle 1 that stretches out sleeve pipe 2, the cylinder needle body of this syringe needle 1 and sleeve pipe 2 internal diameter driving fits, between the two for being slidingly matched.

About 1～the 2mm in sleeve pipe 2 ends is stretched out in the cylinder needle body of syringe needle 1 and the junction at needle point position, and skin injury is less when puncture.

Above-mentioned push rod 3 diameters are less than sleeve pipe 2 internal diameters.

Both internal diameters of above-mentioned guiding tube 4 and sleeve pipe 2 are identical, can guarantee effectively that the drain flexible pipe 7 that passes in the middle of them can play and the extraneous effect that cuts off in inserting.

Above-mentioned guiding tube 4 is 10～30 degree with the angle of sleeve pipe 2, and drain flexible pipe 7 all can insert easily in this scope.

The needle point of above-mentioned syringe needle 1 is the rhizoma sparganic needle point.

Compared with prior art, advantage of the present utility model is as follows:

This utility model is simple in structure, and is simple for production, cheap; Easy and simple to handle, similar to the using method of common puncture needle, easily popularize, each doctor of section all can skillfully operate, grasp; Safe and reliable, operating time is short, and wound is little, several having no adverse reaction or complication, and therapeutic effect is good.It is applicable to hydrothorax, the discharge opeing of all kinds pneumothorax, the aerofluxus treatment of the various causes of disease, and can be by drain flexible pipe 7 at any time to intrapleural injection.Be a kind of the change at present to carrying out the apparatus of complicated closed drainage in the treatment of hydrothorax, pneumatosis by the surgeon.

The explanation of accompanying drawing drawing:

Fig. 1 is this utility model structure cut-away view;

Fig. 2 is this utility model user mode sketch map.

Description of reference numerals is as follows:

1-syringe needle, 2-sleeve pipe, 3-push rod, 4-guiding tube, 5-cover pipe plug, 6-push rod medicated cap, 7-drain flexible pipe.

The specific embodiment:

This utility model in development, exploitation with reference to the structure and the using method of common puncture needle.

Referring to Fig. 1, this utility model comprises sleeve pipe 2, push rod 3, cover pipe plug 5 and syringe needle 1, said sleeve pipe 2 relative push rod 3 one end openings, the sleeve pipe 2 of push rod 3 one ends is provided with and its perforation, the guiding tube 4 that is 20 degree angles, said push rod 3 diameters are less than sleeve pipe 2 internal diameters, it passes on the cover pipe plug 5, in this example, cover pipe plug 5 is the nut with sleeve pipe 2 thread connection, the end of said push rod 3 outside sleeve pipe 2 is provided with the push rod medicated cap 6 of thread connection with it, the other end is connected with syringe needle 1, sleeve pipe 2 end 1mm are stretched out in the cylinder needle body of this syringe needle 1 and the junction at needle point position, its cylinder needle body and sleeve pipe 2 internal diameter driving fits, can be slidingly matched between the two, both internal diameters of said guiding tube 4 and sleeve pipe 2 are identical.

Referring to Fig. 2, when using this utility model, do the long thorn mouth of an about 5mm at point of puncture with knife blade earlier, sting corium, promotion push rod medicated cap 6 makes the needle point that stretches out sleeve pipe 2 front ends be introduced into skin and punctures, make the front portion of sleeve pipe 2 enter pleural space, hold push rod medicated cap 6 then to rear haulage push rod 3, the cylinder needle body that makes sleeve pipe 2 front end syringe needles 1 is after the casing wall slip retreats to guiding tube 4 and sleeve pipe 2 perforations place always, again drain flexible pipe 7 is inserted pleural space through guiding tube 4, sleeve pipe 2, withdraw from guide needle and carry out drainage treatment.
