Abstract
The utility model provides a trocar type puncturing needle for pneumothorax used for pneumothorax puncture operation. It comprises an exterior needle guard and a needle core of which the external diameter adapts to the inner diameter of the exterior needle guard, and the needle core can freely pump in the exterior needle guard; the head of the needle core is a dead end, and the flank of its anterior part is equipped with a liquid outlet hole, and its stern is equipped with a liquor outlet; the needle peak of the exterior needle guard is equipped with an injection orifice. The utility model reduces the traditional pneumatothorax treatment from an operation to a simple paracentesis importing duct, and no stitch needed after tube inserting, and only a simple partial fixing needed. It greatly simplifies the clinical handling procedure, reduces the patient's pain, decreases the patient's expense, and avoids the blemish to organs when the traditional steel needle directly extracts the air. The utility model has the advantages of convenient function, low blemish to flab, low infection rate, being safe and reliable, and has simple structure and low cost, and also is easy for commercial process.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of puncture needle that is used for thoracic cavity (pneumothorax) operation.
Background technology
Existing pneumothorax infusion therapy method, all need surgical operation to cut thoracic wall, sew up thoracic wall after inserting conduit, so not only big to the wound of soft tissue, local infection rate height, the course of disease are longer, and to the patient cause spirit and sensual misery (sebific duct back and forth, easily punctures visceral pleura during insertion, causes bleeding due to trauma, bloody pleural fluid, pachynsis pleurae etc.).
Summary of the invention
This utility model aims to provide that a kind of wound is little, infection rate is low, and the needle guard tubular type pneumothorax puncture needle that can alleviate patient's misery, shorten the course of treatment.
The purpose of this utility model can realize by following measure:
A kind of needle guard tubular type pneumothorax puncture needle comprises outer needle guard and nook closing member, and the external diameter of described nook closing member is suitable with the internal diameter of outer needle guard, and freely twitches in the needle guard outside; The head of described nook closing member is a cecum, and its front end side is provided with liquid outlet, and its afterbody is provided with leakage fluid dram; The pin peak of described outer needle guard is provided with injection orifice.
Described nook closing member is a plastic catheter, and its afterbody is provided with the conduit handle, and the conduit handle is provided with leakage fluid dram.
The afterbody of described outer needle guard is provided with needle handle, and this needle handle and above-mentioned conduit handle are suitable.
The conduit handle of described nook closing member is provided with medicine-pouring hole.
This utility model compared with prior art has the following advantages:
1, this utility model adopts outer casing needle, nook closing member structure combining, traditional pneumothorax treatment is reduced to a simple puncture from an operation imports conduit, must not sew up after the intubate, only do simple fixation in the part and get final product with adhesive plaster, simplified the clinical manipulation program greatly, alleviated the patient suffering, reduced patient's medical expense, when having avoided traditional draw point directly to bleed to the damage of internal organs.
2, this utility model is easy to operate, little to the damage of soft tissue, infection rate is low.
3, this utility model is simple in structure, cost is low, is easy to suitability for industrialized production.
4, nook closing member of the present utility model is made by plastic catheter, and certain pliability is arranged, and enters to be difficult for behind the thoracic cavity giving a discount, be subjected to the thoracic wall extruding indeformable, do not stop up, safe and reliable.

The specific embodiment
A kind of needle guard tubular type pneumothorax puncture needle is made up of the outer needle guard 1 of metal and plastic catheter nook closing member 2 two parts, and the external diameter of plastic cement nook closing member 2 is suitable with the internal diameter of outer needle guard 1, and conduit nook closing member 2 is freely twitched in the needle guard 1 outside; The head of plastic catheter nook closing member 2 is a cecum, and its front end side (can be not ipsilateral) be provided with liquid outlet 3, and its afterbody is provided with conduit handle 4, and is provided with leakage fluid dram 6 and medicine-pouring hole 8 on conduit handle 4; The pin peak of the outer needle guard 1 of metal is provided with injection orifice, and its afterbody is provided with needle handle 7, and needle handle 7 matches with above-mentioned conduit handle 4.
This puncture needle can be made into the model that varies in size, and its outer needle guard is generally the 14-20 pin, and syringe needle is long to be the 3-4 centimetre, and the nook closing member catheter length is the 15-30 centimetre.
Earlier plastic cement nook closing member 2 is inserted in the outer needle guard 1 during use, make the cecum of plastic cement nook closing member 2 not expose the pin peak; On the leakage fluid dram 6 of plastic catheter handle 4, connect syringe or discharging tube or exhaustor again, and medicine-pouring hole 8 usefulness stopples 9 plugs are tight; With hands the needle handle 7 of outer needle cannula 1 is pinched together with plastic cement nook closing member 2, then syringe needle is thrust the site of puncture, insert back (penetrating thoracic wall) fixed jacket needle tubing 1 on the other hand, just plastic catheter 2 pushes thoracic cavity (syringe needle is still on thoracic wall) gently in overcoat needle tubing 1 on the other hand, after treating that nook closing member 2 is pushed into the thoracic cavity certain depth, outer needle guard head is extracted the thoracic cavity, only let the acupuncture needle remain at a certain point core is in the thoracic cavity, with adhesive plaster nook closing member conduit 2 is fixed on the thoracic cavity, outer needle guard 1 pipe metal needle handle that withdraws from and conduit sleeve are lived fixing, in case outer needle guard 1 slides outside the plastic cement nook closing member.
