Technical field
The present invention relates to a kind of cardiovascular operating instrument, specifically a kind of hand-rail type surgical cannula propeller.
Background technology
In heart or Great Vessel Operations, it is often necessary to be inserted into surgical catheters in human body, these intubations completely according to
Insert to operative incision by the hand-held intubation of medical personnel.Requirement of this manual work to operator is higher, hand-held intubation
Stability and accuracy are difficult to grasp.Chinese patent 2012102651582 discloses one kind《Angiocarpy operation cannula fixation clamp》,
The end of intubation can be clamped in operation process using the fixed mount, hand-held fixed mount operation can be in certain journey in catheterization procedure
The Stability and veracity of intubation is improved on degree.But the fixation clamp can only play fixed intubation and be easy to hand-held effect,
Cannot realize advancing the action of intubation, the operation that operator's movement arm realizes intubation be still relied in intubation, for not
For skilled practitioner, in operation process accurately, stably to move arm be extremely difficult.
The content of the invention
Present invention aim to address above-mentioned technical problem, there is provided a kind of simple structure, easy to use, raising intubation operation
The hand-rail type surgical cannula propeller of Stability and veracity.
To solve above-mentioned technical problem, technical scheme is as follows:Hand-rail type surgical cannula propulsion of the present invention
Device includes handle, is fixedly mounted on the runner storehouse of handle upper end, and runner, the runner are provided with by bearing in the runner storehouse
On rocking handle is installed, the upper end in the runner storehouse is fitted with clamp nut, and the inner of the clamp nut in runner storehouse passes through
At least two depression bars are threaded with, at least two depression bars are respectively fixedly connected with the two ends of pressing plate made by elastomeric material, institute
State and be provided with pressing plate pinch roller, pressing plate is made up of plastics or stainless steel material made by the elastomeric material;Pressing plate with turn
Guiding tube is provided between wheel, the guiding tube is arranged on the bulkhead in runner storehouse, the axis of guiding tube is located at the tangent line of runner
On;The edge of the pinch roller and runner is provided with the circular arc-shaped ring groove of matching surgical cannula.
Installing hole is provided with the pressing plate, the pinch roller is rotatably installed in installing hole by rotating shaft.
The runner is provided centrally with jack, and connecting lever is inserted in the jack, and the rocking handle is arranged on connecting lever.
Elongated hole is provided with the bulkhead in the runner storehouse, guiding tube is arranged in elongated hole, and the inner of guiding tube is fixedly connected
In the end of pressing plate.
The hand-rail type surgical cannula propeller adopts runner hand feed, it is to avoid unstable, standard that artificial operation brings
The true defect of property difference, simple structure, easy to use, the stability and accuracy of operation are increased substantially.
Description of the drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the A-A sectional views of Fig. 1.
Fig. 3 is the planar structure schematic diagram of pressing plate.
Fig. 4 is the structural representation of another embodiment of the present invention.
Specific embodiment
With reference to the accompanying drawings and examples the present invention is further described.
As shown in Figure 1 and Figure 2, hand-rail type surgical cannula propeller of the present invention includes handle 1, is fixedly mounted on handle 1
The runner storehouse 2 of upper end, runner 3 is provided with the runner storehouse 2 by bearing, and rocking handle 4 is provided with the runner 3.When using,
Handle 1 is caught to be fixed on the other hand, another handss drive runner 3 to rotate by rocking handle 4.
The upper end in the runner storehouse 2 is fitted with clamp nut 7,8, and the inner of the clamp nut 7,8 in runner storehouse 2 leads to
Cross and be threaded with least two depression bars 9,10.Clamp nut 7,8 is rotated, clamp nut 7,8 is rotated against i.e. with depression bar 9,10
Scalable distance between the two.
At least two depression bars 9,10 are respectively fixedly connected with and pinch roller 12 are provided with the two ends of pressing plate 11, the pressing plate 11,
Pressing plate 11 is made using the elasticity preferably material such as plastics, rustless steel, when the two ends of pressing plate 11 push, presses can pinch roller 12
Tightly on the wheel rim of runner 3.
Such as Fig. 1 embodiments, guiding tube 5,6 is provided between pressing plate 11 and runner 3, the guiding tube 5,6 is fixedly mounted
On the bulkhead in runner storehouse 2, the axis of guiding tube 5,6 is located on the tangent line of runner 3.Surgical cannula 19 passes through guiding tube 5,6, when
When pressing plate 11 and pinch roller 12 are pushed, pinch roller is pressed on surgical cannula 19 on runner 3, with the rotation of runner 3, pushes away forward
Send surgical cannula 19.
As shown in figure 3, being provided with installing hole on the pressing plate 11, the pinch roller 12 is rotatably installed in peace by rotating shaft
In dress hole.In order to the edge for preferably pushing surgical cannula 19, the pinch roller 12 and runner 3 is provided with matching surgical cannula 19
Circular arc-shaped ring groove, pinch roller 12 and runner 3 clamp surgical cannula 19 from upper and lower both sides respectively.
As shown in Fig. 2 the runner 3 is provided centrally with jack, connecting lever 41 is inserted in the jack, the rocking handle 4 is pacified
It is mounted on connecting lever 41.On the one hand the advantage of the structure of this rocking handle 4 can as needed change the connecting lever 41 of different length model, separately
On the one hand rocking handle action can be made more stable.Certainly, as another embodiment of the present invention, it is also possible to directly install rocking handle 4
The non-home position such as the edge in runner 3, rotation crank 4 can drive runner 3 to rotate.
As shown in figure 4, another embodiment of the present invention, is provided with elongated hole, guiding tube 5,6 on the bulkhead in the runner storehouse 2
In elongated hole, the inner of guiding tube 5,6 is fixedly connected on the end of pressing plate 11.The width of elongated hole is straight with guiding tube 5,6
Footpath matches, and the length direction of elongated hole is consistent with the moving direction of pressing plate 11, adjusts clamp nut 7,8, and pressing plate 11 is moved up and down
While, guiding tube 5,6 is also moved up and down therewith and as the circular arc at the edge of runner 3 produces slight inclination, so not only may be used
To realize that pinch roller 12 is pressed on surgical cannula 19 on runner 3, can also realize that surgical cannula 19 pushes the regulation in direction.
In operation, by the front end insertion guiding tube 5,6 of surgical cannula 19, adjusting clamp nut 7,8 makes surgical cannula 19
With the frictional force between runner 3 just, rotation crank 4 can promote surgical cannula 19 to advance.
