Description
Technical field
The present invention relates to medical thrust technical fields, and in particular to a kind of sting device.
Background technology
The double-jacket tube that existing clinical operation uses, often needs underwent operative to place to position of disease and is rinsed and treats, and for
No operation patient or can not be resistant to the patient of operation there is no it is a set of integrate puncture, placement, irrigation and drainage double-jacket tube dress
It sets.Therefore for the existing often only passive drainage of such patient, or interruption water filling irrigation and drainage is repeatedly punctured, curative effect it is also to be difficult to
It is satisfied.
Clinic puncture drainage is that Seldinger sets tube method using more method at present, and the puncture mode of the technology is
Through ultrasound or CT positioning targets penetrating area.It using lidocaine local anaesthesia and is soundd out in target area after sterile drape, after
It uses puncture needle instead and is vertically pierced into epidermis until reaching target depth (can be by positioning such as syringe extraction or ultrasound, CT), insert
Enter seal wire, after determining that seal wire has been enter into target area, exit puncture needle, is used in combination at gauze pressing puncture.It is led along seal wire insertion
Pipe (can be first inserted into for several times along seal wire with the expander of thickness same as conduit, to expand wound road, conduit be made to be easy to logical when necessary
Cross, extract expander, then conduit is inserted into along seal wire), seal wire is extracted, three-way cock and drainage bag are connected.Finally conduit is carried out
Part is fixed, disinfection.Conduit it can be drained or be administered whereby.But such conduit has no individual water inlet line and gives part
Lasting water inlet is rinsed, therefore cannot keep lasting local cleaning action, while local organization, foreign matter, sludged blood etc. also often block
Tube chamber keeps drainage effect unsatisfactory.
And the double-jacket tube for being placed in operation, the ability with continual rinsing drainage, and since it is relatively more advantageous
Placement location, therefore cleaning capacity drains more merely often more preferably clinical effectiveness.But clinically current this used
There is no the functions that independently puncture for class double-jacket tube, therefore for No operation or can not be resistant to the patient of operation, and such disadvantage limits
Its clinical application.
Also, since puncture needle in the prior art, conduit, seal wire are individual components, in piercing process, need point
Other each component of independent operation, step is complex cumbersome, also limits the application of current drainage catheter.

Illustrate the application method of sting device provided by the invention below：
Method one：Suitable for site of puncture dissection, clear (such as seroperitoneum amount is big, and the interference of the institutional frameworks such as no intestinal tube is worn
Pierce path etc.), the low patient of puncture risks.
1, puncture needle 200 is installed in outer tube 100, the installing port of the needle guard 202 and outer tube 100 of puncture needle 200
103 are screwed connection, and needle core 201 is screwed with needle guard 202 and is connect, limited 202 position of needle guard using connector 102
Position makes the front end of the tip of needle core 201, the front end of needle guard 202, the front end of connector 102, outer tube 100 form a back taper
Structure.
2. the best site of puncture of localization by ultrasonic and paracentesis depth, are used in combination marked.It sterilizes, 2% benefit is used after drape
Cacaine local anaesthesia.It is used in combination blade to cut sizeable " ten " font notch at label point of puncture.
3. operating the corresponding site that the sting device protrudes into portion into the human body, the position of outer tube 100 is constant, takes out
The needle core 201 of puncture needle 200 in outer tube 100 connects syringe in 202 tail end of needle guard and extracts judgement puncture effect.
4. after choosing proper site and depth, pulling out the needle guard 202 of puncture needle 200, marking 100 depth of outer tube and disappearing
Poison is fixed.
5. inner suction pipe 300 is extend into outer tube 100, liquid is inputted to 100 water inlet 106 of outer tube, liquid is successively
It is expelled to human body corresponding site by water inlet line 107, suction hole, which is handled, is then started and inner suction pipe 300
The negative pressure equipment 500 of connection makes the outer tube 100 for extending into human body and inner suction pipe 300 generate negative pressure, utilizes outer tube
100 and the suction hole of inner suction pipe 300 liquid of human body is drawn, while ambient atmos are by 100 air inlet of outer tube
105 and the tube chamber of admission line 108 and outer tube 100 enter the head end working region of outer tube 100, and by inner suction pipe 300
It draws, ensures the moderate without being damaged to human body of the suction force of inner suction pipe 300.
Method two：Higher suitable for puncture risks, local tissue structures are complicated, need the patient of more accurate operation.
It is connect 1. the needle guard 202 of puncture needle 200 is screwed with the installing port 103 of outer tube 100, makes needle guard 202
Front end, the front end of connector 102, outer tube 100 front end formed an inverted trapezoidal structure (i.e. without 201 structure of needle core).
2. the best site of puncture of localization by ultrasonic and paracentesis depth, are used in combination marked.It sterilizes, 2% benefit is used after drape
Cacaine local anaesthesia.
3. being placed in seal wire using Seldinger puncture methods, size is cut at point of puncture skin along seal wire using blade and closed
Suitable " ten " font notch.
4. using the sting device without needle core 201 in step 1, pipeline of the seal wire in needle guard 202 is set to pass through, while making whole
A sting device enters human body target position along seal wire and reaches target depth.Seal wire is pulled out after reaching target depth, in needle guard
202 tail ends, which connect syringe and extract, to be judged to puncture effect.After reaching ideal effect, 200 needle guard 202 of puncture needle is pulled out.Mark housing
100 depth of pipe is simultaneously sterilized, is fixed.
5. inner suction pipe 300 is extend into outer tube 100, liquid is inputted to 100 water inlet 106 of outer tube, liquid is successively
It is expelled to human body corresponding site by water inlet line 107, suction hole, which is handled, is then started and inner suction pipe 300
The negative pressure equipment 500 of connection makes the outer tube 100 for extending into human body and inner suction pipe 300 generate negative pressure, utilizes outer tube
100 and the suction hole of inner suction pipe 300 liquid of human body is drawn, while ambient atmos are by 100 air inlet of outer tube
105 and the tube chamber of admission line 108 and outer tube 100 enter the head end working region of outer tube 100, and by inner suction pipe 300
It draws, ensures the moderate without being damaged to human body of the suction force of inner suction pipe 300.
Method three：Suitable for needing the patient of lasting seal wire guiding after the puncture of method one.
