Abstract
The utility model discloses an angiocarpy intervening anti-reversing guider, which comprises a puncture needle stand 1, a sleeve 2 and a plunger piston 3, wherein the puncture needle stand 1 is fixed in the middle of the front wall of the sleeve 2 which is provided inside with the plunger piston 3, the center of the plunger piston 3 is axially provided with a guide hole 4, the front opening of the guide hole 4 is provided with an elastic diaphragm seal 5. Because a guide device and anti-reversing control are added and the angiocarpy intervening anti-reversing guider is operated under hermetic condition, the angiocarpy intervene anti-reversing guider is easy and safe to operate, and can prevent blood from flowing back when a guide thread or a guide tube is inserted, the guide thread can be inserted stably and a puncture needle does not generate shift, and thereby the utility model can improve the success rate of intervene cure, lightens labor of medical staff and eases the mental load of patients.
Description
Technical field
This utility model relates to a kind of cardiovascular interventional medical device, and specifically a kind of cardiovascular is got involved anti-reverse guider.
Background technology
The cardiovascular interventional therapy is meant by puncture needle pin chamber, under the diagnostic imaging instrument instructs, lead or conduit is inserted in the patient's blood vessel technology of diagnosing and treating.In clinical manipulation, normally directly thrust blood vessel and again seal wire is penetrated puncture needle pin intracavity with puncture needle, stretch into conduit along seal wire then, in conduit, inject contrast agent or inject medicine again, or inject suppository and do the suppository treatment, also available ordinary syringe is thrust blood vessel, and then syringe unloaded from puncture needle, seal wire is sent in the blood vessel by piercing needle, the weak point that runs in operation is again: penetrate before the seal wire or penetrate in the process of seal wire, can produce backflow of blood, cause hemorrhage and pollution work surface, also easily cause puncture needle displacement injured blood vessel simultaneously, also can cause puncture failure sometimes, need again puncture again.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, easy to operate, can prevent that backflow of blood, seal wire are stable and penetrate and prevent that the cardiovascular that produces the puncture needle displacement from getting involved anti-reverse guider.
For reaching above purpose, the technical scheme that this utility model adopted is: this cardiovascular is got involved anti-reverse guider, by the puncture needle needle stand, sleeve, plunger constitutes, the puncture needle needle stand is fixed on telescopic front bulkhead middle part, plunger is located in the sleeve, it is characterized in that establishing pilot hole vertically at the center of plunger, in use, when seal wire or conduit pass in pilot hole, can reach stable orientation, reduce deflection, in the intravasation of puncture needle pin chamber, establish elasticity envelope film at the front end oral area of pilot hole, seal wire or conduit pass from the centre bore of elasticity envelope film, under the effect of elasticity envelope film,, prevent that blood from refluxing with the pilot hole sealing.This utility model is also implemented by following measure: described elasticity envelope film is the conical plastics film cylinder, end opening is bonded on the inwall on guide apertures edge, suitable for reading is automatic shutoff mouth, when blood refluxes, blood enters the inwall and the taper elasticity of pilot hole and seals between the outer wall of film, make suitable for reading being adjacent on the outer wall of seal wire or conduit, prevent that blood from refluxing; Oral area is also established sealing-plug in the pilot hole rear end, when puncture, can keep the airtight of pilot hole, on the front end outer wall of plunger, establish two ring sealing ring draw-in grooves, be embedded in sealing ring at the sealing ring draw-in groove, make plunger in sleeve, seal slip, and make the barrel bore of plunger front end form enclosed cavity.When using this utility model, earlier puncture needle is installed in and wears on time pin needle stand, puncture the pumpback plunger, in the sleeve cavity of plunger front end, flow into if see blood, show promptly and puncture successfully that the sealing-plug with rear end, plunger guide hole takes off again, and seal wire is penetrated in pilot hole, from the hole of elasticity envelope film, enter in the puncture needle needle stand, in the puncture needle intravasation, insert conduit along seal wire more again, whole process is carried out under the diagnostic imaging instrument instructs.
The beneficial effects of the utility model are: compare with present employed interventional therapy puncture needle, owing to added guider and anti-reverse current control, and under air-proof condition, operate, so in inserting seal wire or catheter procedure, easy and safe to operate, can prevent in inserting seal wire or catheter procedure that blood from refluxing, seal wire can stablize and penetrate, puncture needle can not produce displacement yet, can improve the interventional therapy success rate, alleviates medical personnel's labor intensity and patient's mental burden.
Description of drawings
Fig. 1 is that this utility model structure is along the axis cross-sectional schematic.
Fig. 2 penetrates the application state sketch map for this utility model seal wire.
The specific embodiment
Make this utility model with reference to accompanying drawing 1.This cardiovascular is got involved anti-reverse guider, constitute by puncture needle needle stand 1, sleeve 2, plunger 3, puncture needle needle stand 1 is fixed on the front bulkhead middle part of sleeve 2, plunger 3 is located in the sleeve 2, pilot hole 4 is established at center at plunger 3 vertically, seal wire or conduit can reach stable orientation when passing in pilot hole 4, reduce deflection, in the intravasation of puncture needle pin chamber, establish elasticity envelope film 5 at the front end oral area of pilot hole 4, seal wire or conduit pass from the centre bore of elasticity envelope film 5, under the effect of elasticity envelope film 5, with pilot hole 4 sealings, prevent that blood from refluxing.Described elasticity envelope film 5 is the conical plastics film cylinder, end opening is bonded on the inwall on 4 mouthfuls of edges of pilot hole, suitable for reading is automatic shutoff mouth, when blood refluxes, blood enters the inwall and the taper elasticity of pilot hole 4 and seals between the outer wall of film 5, make suitable for reading being adjacent on the outer wall of seal wire or conduit, prevent that blood from refluxing; Also establish sealing-plug 6 at pilot hole 4 rear end oral areas, when puncture, can keep the airtight of pilot hole 4, on the front end outer wall of plunger 3, establish two ring sealing ring draw-in grooves, be embedded in sealing ring 7 at the sealing ring draw-in groove, make plunger 3 in sleeve 2, seal slip, and make sleeve 2 inner chambers of plunger 3 front ends form enclosed cavity 8.
