Description
Technical field
The present invention relates to a kind of medical puncturing apparatus, more particularly, to a kind of pneumothorax puncture needle.
Background technology
Thoracocentesis is one of clinical conventional diagnostic method, the pressure its object is to clarifying a diagnosis and mitigating internal organs,
Its main operational steps is：(1) in selected point of puncture inserting needle local anaesthesia；(2) puncture needle is checked, prepares to puncture；(3)
Patient is punctured in point of puncture, and shown in slow inserting needle to B ultrasonic positioning during depth, can try pumpback, such as be taken out without gas or liquid
Go out, appropriate inserting needle can be continued, extracted out if any gas or liquid, then stop continuing inserting needle, aspirate intrathoracic gas or liquid,
Complete to puncture；(4) when being needed to intrapleural injection after puncture is finished, puncture needle need to be extracted, is injected with syringe；(5) complete
After above-mentioned steps, need to be covered at puncture with sterile gauze, blend compounds cloth is fixed.
Existing puncture needle is difficult accurately to hold penetration depth, often needs multiple pumpback, when chest intracavity gas or liquid are taken out fewer and fewer,
Visceral pleura increasingly presses close to partial pleura, and patient such as thinks that extract gas or liquid as far as possible needs conversion needle tip position often, this
Sample is very easily damaged to visceral pleura, internal organs.If the hydrops amount in chest is few, point of puncture position is on the lower side
Or site of puncture is when closing on important organ or blood vessel, so it is easier to damage；When being needed to intrapleural injection after puncture is finished,
Puncture needle need to be extracted, is injected with syringe, operated relatively complicated.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of simple structure, syringe needle thorn that is easy to operate, being prevented from puncture needle
Hinder the pneumothorax puncture needle of important organ.
The technical solution adopted for the present invention to solve the technical problems is：Pneumothorax puncture needle, including the needle tubing with pointed syringe needle,
Also include nook closing member, spring, the needle tubing afterbody is provided with grip part, the liquid collecting cavity for connecting needle tubing pin hole be provided with grip part,
With diameter greater than the pinhole diameter, nook closing member is that some cylinders of guiding gutter are provided with outer circumferential walls to liquid collecting cavity, and nook closing member is installed
Can slide in needle tubing and wherein, grip part tail end is provided with the through hole passed through for nook closing member, spring housing is placed on nook closing member
In liquid collecting cavity, the annular stop block with diameter greater than pinhole diameter is provided with nook closing member outer circumferential walls, the limited block is placed in liquid collecting cavity
Interior and contacted with spring, in nature positioned at beyond the position of needle tubing syringe needle, nook closing member front end is located at when puncturing for nook closing member front end
In needle tubing pin hole.
Wherein, the nook closing member is provided centrally with injection orifice, and the injection orifice is axially through nook closing member.
Wherein, pod apertures are provided with the grip part.
It is further that the nook closing member front end is circular blunt nosed.
It is further that identification rings are provided with the outer circumferential walls of nook closing member tail position, the identification rings are located at outside grip part.
It is further that grip part is connected to one with needle tubing.
The beneficial effects of the invention are as follows：Compared to existing puncture needle, pneumothorax puncture needle of the present invention increased prevents internal important organ
The nook closing member being wounded by stabbing, nook closing member is located in pin hole when puncturing, and nook closing member extends over syringe needle after puncture needle head punctures partial pleura
Position, it is to avoid after syringe needle enters thoracic cavity, due to being difficult to hold paracentesis depth, adjust the position of puncture repeatedly and cause naked
The sharps injury of dew occurs to the situation of important organ in thoracic cavity；Needle tubing afterbody is provided with the grip part with liquid collecting cavity, on nook closing member
Annular stop block be placed in liquid collecting cavity and contacted with spring, spring can adjust nook closing member position according to stressing conditions；Grip part
On be provided with the pod apertures of external suction device, intrathoracic gas and liquid enter liquid collecting cavity by the guiding gutter set on nook closing member
Afterwards, discharged by pod apertures；Nook closing member is provided centrally with the injection orifice of insertion nook closing member body, needs to be noted in thoracic cavity after puncture is finished
During medicine, the rubber hose of connection syringe can be connected in nook closing member afterbody set, just can be to intrapleural injection without extracting puncture needle, letter
Operating process is changed；Identification rings are additionally provided with the outer circumferential walls of nook closing member afterbody, patient just can sentence by judging the position of identification rings
It is disconnected to puncture progression, it is to avoid multiple pumpback.
