Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and a kind of compact conformation is provided, and easy to operate, precise control is flexible, realizes the slotting device that send of angiocarpy bracket that quick inserting send.
For achieving the above object, the technical scheme that this utility model adopts is: this angiocarpy bracket is inserted and sent device, it is characterized in that: by rack platform, be positioned at the conduit conveying mechanism on rack platform, the guiding mechanism that is positioned at rack platform front end forms, described rack platform bottom is provided with telescopic supporting leg, described guiding mechanism has the pole of the capable of regulating angle of bend being fixedly connected on rack platform, the end of pole is provided with fairlead, fairlead is two halves formula structure articulated structure, locking clasp is locked two halves formula fairlead, described conduit conveying mechanism is by micromachine, driving wheel, pinch roller, travelling gear and control circuit form, driving wheel is made up of the first driving wheel and the second driving wheel, described the first driving wheel directly connects micromachine, the first driving wheel opposite side is fixedly connected with driving gear, driving gear coordinates driving driven gear, driven gear drives the driven gear being positioned on the second driving wheel to rotate, thereby realize the synchronous rotation of the first driving wheel and the second driving wheel, pinch roller is convertible structure, described pinch roller is arranged on turning rod, turning rod is hinged on the support of rack platform, between turning rod and rack platform, be provided with the tension spring for compressing conduit, described in the time of operating position, driving wheel matches with pinch roller, and the work surface position that described driving wheel matches with conduit with pinch roller is provided with annular groove, described control circuit is arranged on rack platform bottom, and with micromachine control connection, the button of the control rotating in control circuit is drawn by wire.
Described driving wheel and pinch roller are the rubber wheel that coefficient of friction is large.
The endoporus of described fairlead is smooth structure.
In described control circuit, be also provided with the knob of controlling micromachine rotating speed speed.
Adopt the beneficial effect of technique scheme: this angiocarpy bracket is inserted the electric inserting that send device to realize in the time doing angiocarpy bracket intervene operation and sent operation, have simple to operate, use safety, advantage quickly and accurately.In the time using this device, catheter end is snapped in fairlead, the middle part of conduit is placed on driving wheel, upset pinch roller, under the effect of tension spring, compress conduit, and the groove at the driving wheel consisting of rubber and pinch roller middle part positions, guaranteed the frictional force that drives conduit to advance.The button advancing by pressure-controlled, micromachine drives conduit to advance, and unclamps button and stops action, retreats button by pressure-controlled, and conduit retreats, the speed of advancing by the controlled rider of adjusting knob.Control knob is drawn by wire, facilitates doctor's operation.
