Description
Technical field
The utility model belongs to medical instrument, especially a kind of thorax puncture outfit.
Background technology
Pleural effusion and pneumothorax are clinical common diseases, such disease mostly uses thoracocentesis at present and thoracic cavity is planted pipe and drawn
The therapeutic modality of stream.It needs to use pneumothorax puncture needle, the puncture needle to be hollow structure using thoracocentesis, its rear end is connected with
The silica gel hose being connect with syringe.When treatment, puncture needle needle point is inserted into chest, and by the nipple of front end of the syringe needle
Emulsion tube is connected, syringe piston rod, pleural effusion or intrathoracic gas is pulled to be inhaled into the pipe of syringe by puncture needle
In cylinder, after device socket to be injected is filled hydrops or gas, emulsion tube is closed with hemostasis clamp, removes syringe, syringe is pushed to live
Plug, by socket hydrops or after gas squeezes out, then syringe connected into emulsion tube, unclamps haemostatic clamp, the thoracic cavity of patient is accumulated
Liquid or gas are extracted again, are so moved in circles, until the pleural effusion of patient or gas extraction is clean.
In carrying out puncturing extraction pleural effusion or gas process using puncture needle, since puncture needle needle point is always positioned at trouble
In person thoracic cavity, and syringe need to be removed and load onto repeatedly, puncture needle needle point is easy to cause to damage to chest inner tissue.
And in extracting pleural effusion or gas process, the pin hole of puncture needle is possible to be blocked by lung tissue, to influence thoracic cavity
The smooth extraction of hydrops or gas.Furthermore pick up syringe repeatedly, two people needed to coordinate, ambient atmos be easily accessible thoracic cavity and
Cause to infect.
Invention content
The purpose of this utility model is to provide a kind of thorax puncture outfit, and pleural effusion is extracted to patient puncture with it
Or normal structure in chest will not be caused to damage in gas process.
The another object of the utility model is to provide a kind of thorax puncture outfit, and thoracic cavity is extracted to patient puncture with it
In hydrops or gas process, puncture needle pin hole will not influence the smooth pumping of pleural effusion or gas because of the blocking of thoracic cavity inner tissue
It takes.
Thorax puncture outfit described in the utility model, including puncture needle, puncture needle rear end is provided with to be connected to puncture needle axis hole
Spliced eye, further include puncture cannula, driving nut and converter, the back segment of puncture needle be provided with external screw thread, puncture cannula
Rear end is provided with limited step, circumferentially offers annular groove on the inner peripheral surface of driving nut front end, puncture cannula is sleeved on
It is sleeved on puncture needle back segment with puncture needle clearance fit, driving nut on puncture needle and is screwed on puncture needle, puncture cannula rear end
Limited step is located in the annular groove of driving nut and annular groove clearance fit；Converter is three-port structure, including its front end
The fluid outlet of fluid inlet, the pump orifice of its rear end and its side, fluid inlet, fluid outlet and pump orifice pass through converter
Interior chamber is connected, and the first check valve is provided at fluid inlet, only fluid is allowed to enter converter from fluid inlet
Chamber in, fluid outlet is provided with the second check valve, only allow fluid out of converter chamber through fluid outlet
Outflow, converter are plugged on by fluid inlet in the spliced eye of puncture needle rear end.
The puncture cannula front end offers the fluid inlet hole being connected to puncture cannula axis hole.
When puncture procedure, first rotation driving nut makes puncture needle be moved axially in puncture cannula, until puncture needle needle point
Just expose outside puncture cannula front-end port, then puncture needle is inserted into together with puncture cannula in chest, it is then anti-again
Nut is driven to rotation, puncture needle needle point is made to be retracted in puncture cannula.After the nipple of front end of the syringe needle is plugged on converter
In the pump orifice at end, syringe piston rod is pulled, pleural effusion or intrathoracic gas are by puncture cannula port through puncture needle axis
Hole, fluid inlet, the first check valve enter in converter chamber and syringe socket, after device socket to be injected fills with, push note
Emitter piston rod, syringe socket and the indoor pleural effusion of converter chamber or intrathoracic gas are through the second check valve from fluid
Outlet is discharged, repeatedly pulling and push injection device piston rod, until chest hydrops or intrathoracic gas are completely drawn out.
The fluid inlet hole that puncture cannula front end opens up can prevent puncture cannula port from being blocked by thoracic cavity inner tissue and make chest
Chamber hydrops or intrathoracic gas cannot enter in puncture cannula.
The utility model, in the pleural effusion for extracting patient or intrathoracic gas, is punctured due to having this kind of structure
Needle needle point is always positioned in puncture cannula, therefore will not be organized to cause to damage to patient lungs；Turn there are two check valve due to having
Parallel operation, in operation, syringe do not have to remove from puncture outfit that chest hydrops or intrathoracic gas can be completed
It extracts, so as to avoid frequent grafting and removes the troublesome operations of syringe, easy to operate, only operation can be completed in one people of need,
Also avoid the infection risk caused by ambient atmos enter thoracic cavity simultaneously；Due to offering and puncturing in puncture cannula front end
The fluid inlet hole of casing axis hole connection, even if chest inner tissue blocks puncture cannula port, pleural effusion or thoracic cavity
Interior gas can also be entered by the fluid inlet hole in puncture cannula, therefore enable the extraction of pleural effusion or chest intracavity gas
It is smoothed out.
