Description
technical field
The present invention relates to a kind of cardiovascular operating instrument, is a kind of jaw type Angiocarpy operation 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 jaw type Angiocarpy operation 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: jaw type Angiocarpy operation cannula propeller of the present invention comprises determines lever, dynamic lever, described front end of determining lever is fixedly connected with side plate, the center of described side plate is provided with ratchet shaft by bearing, between described ratchet shaft and side plate, return spring is installed, ratchet the tip of the axis connects dynamic lever, ratchet shaft is set with the ratchet cover plate, the ratchet mechanism of single direction rotation is provided with between the described ratchet cover plate and ratchet shaft, determining to be provided with tube seat between lever and ratchet shaft, described tube seat is fixedly connected on to be determined on lever and is arranged on the tangent line place of the ratchet cover plate, tube seat is provided with notch towards the tube wall of the ratchet cover plate, with the groove mated with the notch on tube seat on the excircle of the described ratchet cover plate.
Described tube seat is the groove be made up of multiple spill pulley.
On ratchet shaft, between the ratchet cover plate and dynamic lever, be fixedly connected with discoid cover plate, described dynamic lever is fixedly connected on the outside of cover plate.
On ratchet shaft, between the ratchet cover plate and dynamic lever, be fixedly connected with discoid cover plate, the outside of described ratchet shaft is provided with installing hole, and described dynamic lever is inserted in the installing hole of ratchet shaft.
This propeller adopts the ratchet cover plate to advance intubate to advance, and avoid the defect that manual operation brings, structure is simple, easy to use, and stability and the accuracy of operation increase substantially.

detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1 and Figure 2, jaw type Angiocarpy operation cannula propeller of the present invention comprises determines lever 1 and dynamic lever 2, described front end of determining lever 1 is fixedly connected with side plate 3, the center of described side plate 3 is provided with ratchet shaft 4 by bearing, is provided with return spring 10 between described ratchet shaft 4 and side plate 3.As shown in Figure 3, this spring 10 can adopt torsion spring also can adopt extension spring, and its effect is can self-return after ratchet shaft 4 turns over certain angle.The end of ratchet shaft 4 connects dynamic lever 2, ratchet shaft 4 is set with the ratchet cover plate 5, is provided with the ratchet mechanism of single direction rotation between the described ratchet cover plate 5 and ratchet shaft 4, can promote the ratchet cover plate 5 synchronous rotary when ratchet shaft 4 turns clockwise time; When ratchet shaft 4 is rotated counterclockwise time, skid between ratchet shaft 4 and the ratchet cover plate 5, the ratchet cover plate 5 can not rotate thereupon.The concrete form of this ratchet mechanism can have multiple, as shown in Figure 5, the inner periphery of the ratchet cover plate 5 is provided with ratchet, the excircle of ratchet shaft 4 corresponding with it is then provided with ratchet, this ratchet is hinged in the groove of ratchet shaft 4 excircle, and utilizes torsion spring to make it have the ability of return.When ratchet shaft 4 turns clockwise, the front end of ratchet is stuck in ratchet, promotes the ratchet cover plate 5 synchronous rotary; When ratchet shaft 4 is rotated counterclockwise, ratchet is depressed by the inclined-plane of ratchet, and ratchet shaft 4 can be rotated counterclockwise without restriction.Certainly, also ratchet can be arranged on the inner peripheral surface of the ratchet cover plate 5, and ratchet be arranged on the excircle of ratchet shaft 4.
Determining to be provided with tube seat 6 between lever 1 and ratchet shaft 4, described tube seat 6 is fixedly connected on to be determined on lever 1 and is arranged on the tangent line place of the ratchet cover plate 5, tube seat 6 is provided with notch towards the tube wall of the ratchet cover plate 5, with the groove mated with the notch on tube seat 6 on the excircle of the described ratchet cover plate 5.During use, intubate 9 is inserted in tube seat 6, and the ratchet cover plate 5 is pressed in intubate 9 by the notch on tube seat 6, when the ratchet cover plate 5 rotates time, utilizes frictional force to promote intubate 9 pushed forward.
Described tube seat 6 is the grooves be made up of multiple spill pulley 61.The side of multiple spill pulleys 61 arranged together forms the cannula passage of a groove-like, so both can meet the requirement that intubate is passed through, and can reduce again intubate 9 and the frictional force of tube seat 6, make the promotion of the ratchet cover plate 5 easier.
As shown in Figure 2, on ratchet shaft 4, between the ratchet cover plate 5 and dynamic lever 2, be fixedly connected with discoid cover plate 7, described dynamic lever 2 is fixedly connected on the outside of cover plate 7.The ratchet cover plate 5 is between cover plate 7 and side plate 3, plays a protective role to ratchet mechanism, and presss from both sides when the ratchet cover plate 5 can be avoided to rotate and cause to seize up into foreign body.
As shown in Figure 3, on ratchet shaft, ratchet 4 coils between 5 and dynamic lever 2 and is fixedly connected with discoid cover plate 7, and the outside of described ratchet shaft 4 is provided with installing hole, and described dynamic lever 2 is inserted in the installing hole of ratchet shaft 4.Dynamic lever 2 adopts dismountable mounting structure, is convenient to the initial position adjusting dynamic lever 2.
In operation, inserted in tube seat 6 front end of intubate 9, hold and determine lever 1 and dynamic lever 2, continuous pressing can promote intubate 9 and advance.
