Guide wire thrusterTechnical field
The present invention relates to technical field of medical instruments, a kind of guide wire thruster.
Background technology
Along with the continuous progress of medical skill, Minimally Invasive Surgery is widely used in various diseases treatment, including brain bloodThromboembolism treatment etc. in pipe disease, Cerebrovascular stenosis interventional therapy, acute ischemic cerebrovascular disease time window.In Minimally Invasive SurgeryNeeding interventional therapy, doctor carries out the excision of focus in all kinds of apparatuses being sent into patient body by seal wire.Seal wire is being delayed by doctorDuring slow feeding human body, seal wire bending often occurring, traveling has some setbacks, and needs often to arrange seal wire, adds operationTime, the problem bringing misery to patient.
Summary of the invention
It is an object of the invention to provide a kind of guide wire thruster, be susceptible to bending with solution seal wire in getting involved operation,Problem during Operation Fee.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of guide wire thruster, it includes that box body, the top of described box body are provided with seal wire box, and the top of seal wire box can be opened,Seal wire box is provided with hole with the connecting portion of box body, is provided with the drivewheel and driven pulley contacted with each other, the side of drivewheel in box bodyPart extends the sidewall of box body, and the rotating shaft of drivewheel is fixed on box body, and the rotating shaft of driven pulley is fixed on box by connecting rodOn the sidewall of body, the bottom of box body is provided with guide wire exit openings pipe, and the contact point of hole, guide wire exit openings pipe, drivewheel and driven pulley is positioned atOn straight line.
Preferably, described connecting rod is installed in orbit, and the bottom of connecting rod is provided with spring, and spring bottom is fixed on the side of box bodyOn wall.
Preferably, described drivewheel, the sidewall of driven pulley are provided with decorative pattern.
Preferably, it is packed with having sprayed the sponge of heparin sodium saline in described guide wire exit openings pipe.
The present invention in use, put in seal wire box by doctor by neat for seal wire, and by one end of seal wire from hole, activelyWheel and the contact point of driven pulley, guide wire exit openings pipe pass seal wire box and box body successively, enter human body with medical apparatus and instruments after connecting,During pushing, doctor at the uniform velocity stirs the side of drivewheel, seal wire along with the rotation of drivewheel Yu driven pulley, by slowly, evenIn the feeding human body of speed, bending will not occur.
The invention have the benefit that
(1) present invention pass through drivewheel, the rotation of driven pulley so that seal wire is no longer bent over, by slowly, at the uniform velocity be sent to peopleIn body, doctor without arranging seal wire, has saved operating time in operation process, alleviates the misery of patient；
(2) present invention is by the rotating shaft clamping of driven pulley in connecting rod, and the tail end of connecting rod arranges spring, can make leading of different thicknessesSilk all contact points from drivewheel with driven pulley pass so that the present invention is applicable to all kinds of operation；
(3) present invention drivewheel, driven pulley side on decorative pattern is set, the coefficient of friction with seal wire can be increased, make seal wireAt the uniform velocity, smoothly advance；
(4) present invention is packed with having sprayed the sponge of heparin sodium saline in guide wire exit openings pipe, can effectively prevent exogenesis bloodBolt forms and reduces interior former thrombosis.

Detailed description of the invention
The present invention is further detailed explanation below in conjunction with the accompanying drawings.
A kind of guide wire thruster as shown in Figure 1 to Figure 3, it includes that box body 1, the top of box body 1 are provided with seal wire box 8, leadThe top of silk box 8 can be opened, and seal wire box 8 is provided with hole 7 with the connecting portion of box body 1, is provided with the active contacted with each other in box body 1Wheel 2 and driven pulley 3, drivewheel 2, the sidewall of driven pulley 3 be provided with decorative pattern, and the lateral section of drivewheel 2 extends the side of box body 1Wall, the rotating shaft of drivewheel 2 is fixed on box body 1, and the rotating shaft of driven pulley 3 is fixed on the sidewall of box body 1 by connecting rod 4, evenBar 4 is installed in track 9, and the bottom of connecting rod 4 is provided with spring 5, is fixed on the sidewall of box body 1 bottom spring 5；The end of box body 1Portion is provided with guide wire exit openings pipe 6, is packed with having sprayed the sponge of heparin sodium saline in guide wire exit openings pipe 6；Hole 7, guide wire exit openings pipe 6,The contact point of drivewheel 2 and driven pulley 3 is positioned on straight line.
The present invention in use, put in seal wire box 8 by doctor by neat for seal wire, and by one end of seal wire from hole 7, mainDriving wheel 2 and the contact point of driven pulley 3, guide wire exit openings pipe 6 pass seal wire box 8 and box body 1 successively, connect laggard with medical apparatus and instrumentsEntering human body, during pushing, doctor at the uniform velocity stirs the side of drivewheel 2, seal wire along with the rotation of drivewheel 2 with driven pulley 3,By in feeding human body slowly, at the uniform velocity, bending will not occur.
The present invention passes through drivewheel, the rotation of driven pulley so that seal wire is no longer bent over, by being sent to slowly, at the uniform velocityIn human body, doctor without arranging seal wire, has saved operating time in operation process, alleviates the misery of patient；By driven pulleyRotating shaft clamping in connecting rod, the tail end of connecting rod arranges spring, and the seal wire of different thicknesses can be made all from drivewheel and driven pulleyContact point pass so that the present invention is applicable to all kinds of operation.
