Description

A kind of surgical cannula propeller
Technical field
The present invention relates to a kind of cardiovascular operating instrument, specifically a kind of surgical cannula propeller.
Background technique
In heart or Great Vessel Operations, it is often necessary to enter surgical catheters in human body interpolation, these intubations completely according to It is inserted by the hand-held intubation of medical staff to operative incision.This handwork holds intubation to the more demanding of operator Stability and accuracy are difficult to grasp.Chinese patent 2012102651582 discloses a kind of " Angiocarpy operation cannula fixing clamp ", The end of intubation can be clamped in surgical procedure using the fixed frame, fixed frame operation is held in catheterization procedure can be in certain journey The Stability and veracity of intubation is improved on degree.But the fixing clamp can only play fixed intubation and the effect convenient for holding, It cannot achieve the movement for promoting intubation, the operation that the mobile arm of operator realizes intubation still relied in intubation, for not It is accurate in surgical procedure, steadily to move arm be very difficult for skilled practitioner.
Summary of the invention
Present invention aim to address above-mentioned technical problem, provide a kind of structure it is simple, it is easy to use, improve intubation operation The surgical cannula propeller of Stability and veracity.
In order to solve the above technical problems, technical scheme is as follows: a kind of surgical cannula propeller of the present invention It including handle, is fixedly mounted on the runner storehouse of handle upper end, runner is equipped with by bearing in the runner storehouse, on the runner Rocking handle is installed, the upper end in the runner storehouse is fitted with clamp nut, and the inner end of the clamp nut in runner storehouse passes through spiral shell Line is connected at least two compression bars, and at least two compression bars are respectively fixedly connected with the both ends of the pressing plate made of elastic material, described Pinch roller is installed on pressing plate；Guiding tube is provided between pressing plate and runner, the guiding tube is mounted on the bulkhead in runner storehouse, The axis of guiding tube is located on the tangent line of runner；The edge of the pinch roller and runner is provided with the arc-shaped of matching surgical cannula Annular groove.
Mounting hole is provided on the pressing plate, the pinch roller is rotatably installed in mounting hole by shaft.
The runner is provided centrally with jack, and connecting lever is inserted in the jack, and the rocking handle is mounted on connecting lever.
It is provided with long hole on the bulkhead in the runner storehouse, guiding tube is mounted in long hole, and the inner end of guiding tube is fixedly connected In the end of pressing plate.
The surgical cannula propeller uses runner hand feed, avoids that manual operation bring is unstable, accuracy is poor Defect, structure is simple, easy to use, and the stability and accuracy of operation increase substantially.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of one embodiment of the invention.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Fig. 3 is the planar structure schematic diagram of pressing plate.
Fig. 4 is the structural schematic diagram of another embodiment of the present invention.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
As shown in Figure 1 and Figure 2, a kind of surgical cannula propeller of the present invention includes handle 1, is fixedly mounted on handle 1 The runner storehouse 2 at end is equipped with runner 3 by bearing in the runner storehouse 2, is equipped with rocking handle 4 on the runner 3.In use, one Hand catches handle 1 to be fixed, and the other hand drives 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 end of the clamp nut 7,8 in runner storehouse 2 is logical It crosses and is threaded at least two compression bars 9,10.Clamp nut 7,8 is rotated, clamp nut 7,8 is with compression bar 9,10 relative rotation Adjustable distance between the two.
At least two compression bars 9,10, which are respectively fixedly connected with, is equipped with pinch roller 12 on the both ends of pressing plate 11, the pressing plate 11, Pressing plate 11 is made of materials such as elasticity preferable plastics, stainless steels, when 11 both ends of pressing plate push, pinch roller 12 can be made to press Tightly on the wheel rim of runner 3.
Such as Fig. 1 embodiment, 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 push, surgical cannula 19 is pressed on runner 3 by pinch roller, with the rotation of runner 3, to being pushed forward Send surgical cannula 19.
As shown in figure 3, being provided with mounting hole on the pressing plate 11, the pinch roller 12 is rotatably installed in peace by shaft It fills in hole.In order to preferably push surgical cannula 19, the edge of 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 two 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 On connecting lever 41.On the one hand the advantages of this 4 structure of rocking handle, can according to need the connecting lever 41 of replacement different length model, separately On the one hand rocking handle movement can be made more stable.Certainly, as another embodiment of the present invention, directly rocking handle 4 can also be installed In the non-center location 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 invention, long hole, guiding tube 5,6 are provided on the bulkhead in the runner storehouse 2 It is mounted in long hole, the inner end of guiding tube 5,6 is fixedly connected on the end of pressing plate 11.The width of long hole is straight with guiding tube 5,6 Diameter matches, and the length direction of long hole is consistent with the moving direction of pressing plate 11, adjusts clamp nut 7,8, pressing plate 11 moves up and down While, guiding tube 5,6 also moves up and down therewith and as the circular arc at 3 edge of runner generates slight inclination, not only may be used in this way To realize that surgical cannula 19 is pressed on runner 3 by pinch roller 12, it can also realize that surgical cannula 19 pushes the adjusting 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 Frictional force between runner 3 is lucky, and rotation crank 4 can push surgical cannula 19 to advance.
