The utility model is characterized in that a guide wire is be telescopically clamped by the telescopic clamping design; the utility model is suitable for clamping guide wires of different models, and that is to say that the utility model is suitable for clamping guide wires of different thicknesses; a guide wire penetrates through a shaft core from the middle part of the rotation device, distance between the clamping part of a clamping rod and the front end of the guide wire can be reduced, different parts of the guide wire can be respectively and conveniently fixed, and the condition that a turning effect can not be played because of torque force of the guide wire can be avoided; the clamping rod, the push and holding handle and the appearance of the shell can be made to integrally and simultaneously move in the same direction when the push and holding handle or the shell is rotated because of the anti-skid design of the clamping rod, a push and holding handle and the appearance of a shell. The rotation device has the advantages of small size and simple operation.
Description
Technical field:
This utility model relates to a kind of medical apparatus and instruments, for carry out being used for a kind of device that auxiliary seal wire turns in the intervention diagnosis and therapy work in blood vessel.
Background technology:
Interventional radiology is as the third-largest diagnostic and therapeutic system in the modern clinical therapeutics, just with it under the medical image guiding, the collection diagnostic imaging is treated with invasive and is the distinct subject characteristics of one, obtains the approval of academia and extensive patients.Interventional technique is under the guiding of medical imaging device in the blood vessel, utilizes the Clinics and Practices that apparatus carried out operations such as puncture needle, seal wire and conduit.Seal wire is also referred to as guiding steel wire, is modern angiography imperative equipment.The effect of seal wire is that guiding and support catheter are by soft tissues such as subcutaneous tissue, arterial walls, through the puncturing hole intravasation; Guide catheter is by tortuous, hardened blood vessel, and selectivity or super selection enter the vessel branch of inspection; Reinforced tube hardness is beneficial to control lead; Making exchanging pipe uses; The head end softness can reduce the damage of conduit to blood vessel.
Seal wire has certain toughness and elasticity, head end mostly is elbow, to make things convenient for guide catheter to enter different vessel branches, the surface of seal wire scribbles Teflon or heparin-Teflon, purpose is to increase the seal wire smoothness, reduce coefficient of friction and reduce thrombosis, therefore, when reversing seal wire and enter particular blood vessel, usually because the seal wire surface is smooth especially, lack enough frictional force between glove and the seal wire, seal wire is turned to can not be successful, the seal wire distributor seal wire that provides at present turns to auxiliary device to arrest the end that fixed position is positioned at seal wire, and it is very inconvenient to use.
Summary of the invention:
In order to remedy the defective that seal wire turns to auxiliary device, this utility model provides a kind of seal wire clipping rotator, and the clipping rotator of this seal wire can stretch easily and clamp various model seal wires, manually rotation, seal wire is rotated thereupon, the various functions of performance seal wire by required either direction.
The technical scheme that its technical problem that solves this utility model adopts is: this utility model by attachment cap, lock sleeve, overcoat, spring, supporting rod, shell, push away and hold seven parts of handle and form.It is characterized in that attachment cap is positioned at the head end of this device, there is female thread at the attachment cap rear portion, the overcoat front portion has external screw thread to coincide with it, the overcoat middle front part has a groove, attachment cap is connected one with groove with shell by sleeve thread, lock sleeve is positioned at the overcoat front position, the head end of supporting rod is positioned at overcoat, penetrate from lock sleeve and attachment cap rear portion, the anterior skin of supporting rod is a spring, and the spring outside is an overcoat, limited step in the spring front end terminates in the overcoat, the rear end peaks at the anterior limited step of supporting rod, the supporting rod rear portion is that oblate cylinder is fixed in to push away and holds the handle front portion, pushes away to hold that handle is anterior to be the triangular prism profile, and the rear portion is a cylindrical shape, outermost layer is a shell, and to be the triangular prism profile hold handle and coincide and be connected with pushing away shell.Attachment cap, lock sleeve, overcoat, spring, supporting rod, shell, push away and hold handle and be all coaxial hollow-core construction.
Before push away and hold handle, push away and hold handle and in shell, move forward, be fixed in and push away the supporting rod of holding on the handle and move forward thereupon, because the effect of overcoat and two limited steps of supporting rod, spring will be compressed, in supporting rod front end when reach, insert seal wire owing to the front wide and rear narrow design outline of lock sleeve is opened along the attachment cap oral area, follow axle center hole and can hold the handle base apertures and wear the axle center and go out with pushing away from supporting rod under the push mode before holding handle pushing away; Releasing pushes away before pushing away and holding handle, elastic force effect because of spring, supporting rod moves after holding handle with pushing away, the supporting rod front end is owing to the pincers hoop effect of lock sleeve clamps seal wire, the elastic force of spring is big more, the strength of moving behind the supporting rod is strong more, the supporting rod chucking power is also just big more, and is strong more with the clamping action of seal wire, manually rotates this rotator shell or pushes away and hold handle, handle is anterior to be triangular prism because hold at shell rear portion and pushing away, the supporting rod rear portion is the design of oblate column structure, rotational shell or push away hold handle all can make the three simultaneously equidirectional being integral rotatablely move, seal wire rotates thereupon, then the seal wire head end will turn to simultaneously according to the different rotary angle, thus the various functions of performance seal wire.
The beneficial effects of the utility model are: the flexible clipping design clamping different model of can stretching is the seal wire of different thicknesses (4F-7F); Seal wire is from the break-through of clamper axle center and mistake, can make the clamping part of supporting rod and conductive filament head end distance from dwindling as far as possible, avoids can not bringing into play steering-effecting because of seal wire has enough torsion; The rotator volume is little, manipulates simple.
