Description
Technical field
This utility model relates to a kind of cardiovascular operating instrument, is a kind of hand-rail type surgical cannula propeller specifically.
Background technology
In heart or Great Vessel Operations, usually need to enter surgical catheters in human body interpolation, these intubation rely on the hand-held intubate of medical personnel to insert to operative incision completely.The requirement of this manual work to operator is higher, and the stability of hand-held intubate and accuracy are difficult to grasp.Chinese patent 2012102651582 discloses one " Angiocarpy operation cannula fixation clamp ", utilize this fixed mount can clamp the end of intubate in operation process, in catheterization procedure, hand-held fixed mount operation can improve the Stability and veracity of intubation to a certain extent.But this fixation clamp can only play fixing intubate and be convenient to hand-held effect, the action advancing intubate cannot be realized, still rely on operator to move the operation that arm realizes intubate in intubation, for unskilled doctor, it is very difficult for accurately, stably moving arm in operation process.
Summary of the invention
The purpose of this utility model solves the problems of the technologies described above, and provides the hand-rail type surgical cannula propeller that a kind of structure is simple, easy to use, improve intubate operation Stability and veracity.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows: hand-rail type surgical cannula propeller described in the utility model comprises handle, is fixedly mounted on the runner storehouse of handle upper end, by bearing, runner is installed in described runner storehouse, described runner is provided with rocking handle, the upper end in described runner storehouse is fitted with clamp nut, the inner being positioned at the clamp nut in runner storehouse has been threaded connection depression bar, at least two depression bars are fixedly connected on the two ends of pressing plate respectively, and described pressing plate is provided with pinch roller; Between pressing plate and runner, be provided with guiding tube, described guiding tube is arranged on the bulkhead in runner storehouse, and the axis of guiding tube is positioned on the tangent line of runner.
Described pressing plate is provided with installing hole, and described pinch roller is rotatably installed in installing hole by rotating shaft.
The center of described runner is provided with jack, and plug-in mounting connecting lever in described jack, described rocking handle is arranged on connecting lever.
The bulkhead in described runner storehouse is provided with elongated hole, and guiding tube is arranged in elongated hole, and the inner of guiding tube is fixedly connected on the end of pressing plate.
This hand-rail type surgical cannula propeller adopts runner hand feed, and avoid the defect of instability that manual operation brings, poor accuracy, structure is simple, easy to use, and stability and the accuracy of operation increase substantially.

Fig. 1 is the structural representation of this utility model embodiment.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the planar structure schematic diagram of pressing plate.
Fig. 4 is the structural representation of another embodiment of this utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further illustrated.
As shown in Figure 1 and Figure 2, hand-rail type surgical cannula propeller described in the utility model comprises handle 1, is fixedly mounted on the runner storehouse 2 of handle 1 upper end, is provided with runner 3, described runner 3 is provided with rocking handle 4 in described runner storehouse 2 by bearing.During use, catch handle 1 to be fixed on the other hand, another hands drives runner 3 to rotate by rocking handle 4.
The upper end in described runner storehouse 2 is fitted with clamp nut 7,8, and the inner being positioned at the clamp nut 7,8 in runner storehouse 2 has been threaded connection depression bar 9,10.Rotate clamp nut 7,8, clamp nut 7,8 and the relative rotation of depression bar 9,10 and scalable distance between the two.
At least two depression bars 9,10 are fixedly connected on the two ends of pressing plate 11 respectively, described pressing plate 11 is provided with pinch roller 12, pressing plate 11 adopts the materials such as the good plastics of elasticity, rustless steel to make, and time pressing plate 11 two ends press down, pinch roller 12 can be made to be pressed on the wheel rim of runner 3.
As Fig. 1 embodiment, be provided with guiding tube 5,6 between pressing plate 11 and runner 3, described guiding tube 5,6 is fixedly mounted on the bulkhead in runner storehouse 2, and the axis of guiding tube 5,6 is positioned on the tangent line of runner 3.Surgical cannula 19 is through guiding tube 5,6, and when pressing plate 11 and pinch roller 12 press down time, surgical cannula 19 is pressed on runner 3 by pinch roller, along with the rotation of runner 3, and pushed forward surgical cannula 19.
As shown in Figure 3, described pressing plate 11 is provided with installing hole, described pinch roller 12 is rotatably installed in installing hole by rotating shaft.In order to push surgical cannula 19 better, the edge of described pinch roller 12 and runner 3 is provided with the circular arc-shaped ring groove of coupling surgical cannula 19, and pinch roller 12 and runner 3 are respectively from upper and lower both sides clamping surgical cannula 19.
As shown in Figure 2, the center of described runner 3 is provided with jack, plug-in mounting connecting lever 41 in described jack, and described rocking handle 4 is arranged on connecting lever 41.The advantage of this rocking handle 4 structure can change the connecting lever 41 of different length model on the one hand as required, rocking handle action can be made more stable on the other hand.Certainly, as another embodiment of the present utility model, also directly rocking handle 4 can be arranged on the non-home positions such as the edge of runner 3, rotation crank 4 can drive runner 3 to rotate.
As shown in Figure 4, another embodiment of the present utility model, the bulkhead in described runner storehouse 2 is provided with elongated hole, and guiding tube 5,6 is arranged in elongated hole, and the inner of guiding tube 5,6 is fixedly connected on the end of pressing plate 11.The width of elongated hole and the diameter of guiding tube 5,6 match, the length direction of elongated hole is consistent with the moving direction of pressing plate 11, regulate clamp nut 7,8, while pressing plate 11 moves up and down, guiding tube 5,6 also moves up and down thereupon and produces slight inclination along with the circular arc at runner 3 edge, so not only can realize pinch roller 12 is pressed on runner 3 by surgical cannula 19, can also realize the adjustment that surgical cannula 19 pushes direction.
In operation, inserted the front end of surgical cannula 19 in guiding tube 5,6, regulate clamp nut 7,8 to make the frictional force between surgical cannula 19 and runner 3 lucky, rotation crank 4 can promote surgical cannula 19 and advance.
