Angiocarpy bracket is inserted and is sent device
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of easy to operate, use safe angiocarpy bracket to insert to send device.
Background technology
Along with the raising of living standard, the change of life style, cardiovascular disease incidence rate is more and more higher, and the coronary heart disease causing because cardiovascular is narrow has become and has jeopardized one of healthy and safe principal disease of human life.At present, the treatment of coronary heart disease is divided into Drug therapy, surgical operation and interventional therapy three major types.The Drug therapy cycle is long, it is slow to take effect, side effect is large, and patient easily produces the dependency to medicine; Surgical operation can produce permanent injury to patient; Interventional therapy method, because its wound is little, effective, becomes the narrow novel method of current treatment cardiovascular.Coronary artery bracket is by traditional sacculus dilating catheter, support implantable intravascular stenosis area, to prevent restenosis after percutaneous transluminal coronary angioplasty.In the time of interventional therapy, utilize x-ray radiography video surveillance conduit to enter aorta from small artery in human body, the slotting intravascular stent that send of conduit clinically, normally artificial hand-held conduit is by operating manually, insert and send the time long, manipulation is inconvenient, inserts the Stability and veracity sending and is affected.
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.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is the structural representation of the fairlead of amplification.
The specific embodiment
As shown in Fig. 1,2,3, a kind of angiocarpy bracket is inserted and is sent device, by rack platform 9, be positioned at 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 11, and described supporting leg 11 is expansion joint structure, can make rack platform maintenance level by the length that regulates supporting leg.Described guiding mechanism has the pole 13 of the capable of regulating angle of bend being fixedly connected on rack platform, the end of pole is provided with fairlead 1, the endoporus of described fairlead is smooth structure, and fairlead is two halves formula structure articulated structure, and locking clasp is locked two halves formula fairlead.Described conduit conveying mechanism is made up of micromachine 17, driving wheel, pinch roller 5, travelling gear and control circuit 12, driving wheel is made up of the first driving wheel 7 and the second driving wheel 4, described the first driving wheel 7 directly connects micromachine 17, the first driving wheel opposite side is fixedly connected with driving gear 8, driving gear 8 coordinates driving driven gear 6, driven gear 6 drives the driven gear 3 being positioned on the second driving wheel to rotate, thereby realizes the synchronous rotation of the first driving wheel 7 and the second driving wheel 4.Pinch roller 5 is convertible structure, described pinch roller is arranged on turning rod 14, turning rod 14 is hinged on the support 16 of rack platform, between turning rod and rack platform, be provided with the tension spring 15 for compressing conduit 2, described in the time of operating position, driving wheel matches with pinch roller, and described driving wheel is provided with annular groove with the work surface position that pinch roller matches with conduit 2; Described control circuit 12 is arranged on rack platform bottom, and with micromachine control connection, the button of the control rotating in control circuit is drawn on panel 10 by wire, is also provided with the knob of controlling micromachine rotating speed speed in described control circuit, and this button is arranged on panel 10.Described driving wheel and pinch roller are the rubber wheel that coefficient of friction is large, in drive conduit 2 is advanced, do not damage conduit, ensure carrying out smoothly of intervene operation.
This utility model describes by accompanying drawing, in the situation that not departing from this utility model scope, can also carry out various conversion and be equal to replacement this utility model patent, therefore, this utility model patent is not limited to disclosed specific implementation process, and should comprise the whole embodiments that fall within the scope of this utility model Patent right requirement.
