Abstract
The invention relates to an instrument for cardiovascular surgery, and particularly relates to a handheld surgical cannula pusher. The handheld surgical cannula pusher comprises a rotating wheel bin and a cover plate, wherein the cover plate is hinged to the upper end of the rotating wheel bin; the rotating wheel bin is of a shell structure of which the upper end is opened; a rotating wheel is mounted inside an inner chamber of the rotating wheel bin by a bearing; an arc-shaped groove is formed in the outer circumference of the rotating wheel; a rotating wheel bin handle and a cover plate handle are respectively and correspondingly arranged on the rotating wheel bin and the cover plate; a cannula slot is fixedly formed in the inner side of the cover plate; the cannula slot is provided with a notch in the cannula wall towards a ratchet plate; a mounting hole is formed in a wheel shaft of the rotating wheel; a crank arm provided with a hand wheel is fixedly mounted in the mounting hole. The pusher is used for pushing a cannula to move forwards by manually rocking the rotating wheel, and the pressure of the rotating wheel to the cannula is controlled by the handle, so that defects caused by manually pushing the cannula are avoided, and the handheld surgical cannula pusher is simple in structure, convenient to use and greatly improved in operation stability and accuracy.
Description
Technical field
The present invention relates to a kind of cardiovascular operating instrument, is a kind of hand held 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 object of the invention is to solve the problems of the technologies described above, the hand held surgical cannula propeller that a kind of structure is simple, easy to use, improve intubate operation Stability and veracity is provided.
For solving the problems of the technologies described above, technical scheme of the present invention is as follows: hand held surgical cannula propeller of the present invention comprises runner storehouse, is hinged on the cover plate of upper end, runner storehouse, described runner storehouse is the shell structure of upper end open, by bearing, runner is installed in the inner chamber in runner storehouse, the excircle of described runner is provided with arc groove, on described runner storehouse and cover plate, correspondence is provided with runner storehouse lever and cover plate lever respectively, the inner side of described cover plate is installed with tube seat, and described tube seat is provided with notch towards the tube wall of the ratchet cover plate; The wheel shaft of described runner is provided with installing hole, in described installing hole, fixedly mounts the connecting lever with handwheel.
Described cover forward end, with the hangers to downward-extension, described hangers is provided with hangers axle, and the upper end of described runner storehouse housing is provided with axis hole, and described hangers axle is arranged in the axis hole in runner storehouse.
This propeller adopts hand runner to advance intubate to advance, and lever controls runner to the pressure of intubate, and avoid the artificial defect advancing intubate to bring, structure is simple, easy to use, and stability and the accuracy of operation increase substantially.
