Most of these cannula operations rely on manual work, and the stability and accuracy of the hand-held cannula is difficult to master due to the small insertion opening and the relatively flexible tubing. Chinese patent 2014107409122 discloses a clamp type cardiovascular surgery cannula propeller which adopts the relative motion of a clamp type fixed grab handle and a movable grab handle to drive a ratchet disc at the front end of the grab handle to rotate, and the rotating ratchet disc drives a cannula to advance. The clamp type cardiovascular operation cannula propeller avoids the defects caused by manual cannula operation, and the stability and accuracy of the operation are greatly improved. However, the structure is relatively complex, so that the failure rate is high; in addition, the clamp type grab handle has large volume and large action amplitude, the disassembly and assembly operations of the propeller are complex, and the requirements of narrow operation space and fine operation cannot be met.

Detailed Description
The invention will be further described with reference to the drawings and examples.
As shown in fig. 1, the pusher for surgical cannulas according to the present invention includes a balloon 1, and an introduction tube 2 and an extraction tube 3 symmetrically disposed at two ends of the balloon 1, wherein the introduction tube 2 and the extraction tube 3 are located on the same central axis 10, so that a surgical cannula 11 is inserted into the introduction tube 2 and the extraction tube 3. The balloon 1 is made of soft and elastic materials such as silica gel, rubber and the like, is deformed when being squeezed by hand, and can quickly recover the shape after the hand is released. The inlet pipe 2 and the outlet pipe 3 are made of hard materials which are not easy to deform, such as stainless steel, hard plastic and the like. The ingress pipe 2 and the egress pipe 3 are fixedly connected with the balloon 1 by adopting an adhesive, and can be connected with the balloon 1 into a whole by adopting a casting technology.
The inner wall of the balloon 1 is fixedly connected with a mounting plate 4 and a guide sleeve 5, the mounting plate 4 is a plate body perpendicular to the central axis, the edge of the mounting plate 4 is fixedly connected with the inner wall of the balloon 1, a through hole is formed in the center of the mounting plate 4 and positioned at the central axis 10 so that an operation cannula 11 passes through the mounting plate 4, the mounting plate 4 is made of hard materials, and the inner wall of the balloon supporting the position enables the balloon not to be concavely deformed; the guide sleeve 5 is positioned between the delivery pipe 3 and the mounting disc 4, an arc-shaped elastic sheet 6 is sleeved in the guide sleeve 5 in a sliding manner, one end of the elastic sheet 6 is fixedly connected to the mounting disc 4, the other end of the elastic sheet is fixedly connected with a friction plate 7, the guide sleeve 5 is a tubular body with a guide hole, the guide sleeve is fixedly connected to the inner wall of the balloon 1 far away from the central axis 10, the axis of the guide hole is parallel to the central axis 10, and the middle section of the elastic sheet 6 is inserted into the guide hole of the guide sleeve 5, so that the elastic sheet can freely slide in the guide hole and can not rotate around the central axis 10 under the constraint of the guide sleeve 5. The two ends of the elastic sheet 6 are close to the central axis 10, the distance between the middle section and the central axis 10 is larger than the two ends, the connection point of the elastic sheet 6 and the mounting plate 4 is positioned around the through hole, the distance between the friction sheet 7 and the central axis 10 is slightly larger than the radius of the operation cannula 11, and when the operation cannula 11 is mounted, the friction sheet 7 is very close to but does not contact with the operation cannula 11 in a loose state, and the elastic sheet 6 is stressed to press the friction sheet 7 to rapidly contact with the operation cannula 11. As shown in fig. 2, the friction plate 7 is semi-arc, the elastic plates 6 are symmetrically arranged on two sides of the central axis 10 in pairs, the number of the elastic plates can be 2 or four, and of course, the number of the elastic plates 6 and the guide sleeve 5 is identical to the number of the friction plates 7. The corresponding friction plates 7 are symmetrically arranged on two sides of the central axis 10, and the operation cannula 11 positioned on the central axis 10 is in a surrounding and clamping state. When the surgical cannula 11 is used, the surgical cannula 11 is inserted into the balloon 1 from the ingress pipe 2, the cavity surrounded by the friction plates 7 is finally led out from the egress pipe 3, and when the surgical cannula 11 needs to be pushed forward, as long as the balloon 1 is held by hand and extruded, one end of the elastic sheet 6 with the friction plates 7 is close to the central axis 10 after being extruded, the friction plates 7 are pressed on the surgical cannula 11, the friction plates 7 are clamped around the surgical cannula 11 in an annular mode, and at the moment, the elastic sheet 6 can be continuously extruded to drive the surgical cannula 11 to move in the direction of the egress pipe 3 through the friction plates 7. The check device is arranged in the inner cavity of the ingress pipe 2, and when the hand spring sheet 6 is loosened to rebound after the balloon 1 is extruded, the check device can clamp the surgical cannula 11 to prevent the surgical cannula 11 from rebounding. Repeatedly pressing the balloon 1 to press the elastic sheet 6 can continuously move the surgical cannula 11 in the direction of the guide tube 3.
As shown in fig. 1 and 3, the non-return device comprises an end cover 8 and a plurality of claw pieces 9 connected to the end cover 8, the end cover 8 is of a circular sheet structure with an outer diameter larger than that of the ingress pipe 2, the end cover 8 is positioned at the outer end of the ingress pipe 2, the center of the end cover 8 is provided with an ingress hole 81, the claw pieces 9 are uniformly distributed around the ingress hole 81, the outer ends of the claw pieces 9 arranged parallel to the axis of the ingress pipe 2 are fixedly connected to the end cover 8, the inner ends of the claw pieces 9 penetrate through the ingress pipe 2 and extend into the inner cavity of the balloon 1, the claw pieces 9 around the edge of the ingress hole 81 enclose a tubular structure, and the inner diameter of the tubular structure is slightly larger than that of the surgical cannula 11 so that the surgical cannula 11 can be smoothly inserted into a cavity enclosed by the ingress hole 81 and the claw pieces 9. The junction of the inner wall of the balloon 1 and the ingress pipe 2 is provided with a horn-shaped transition section 12, the inner end of the claw piece 9 is provided with a convex block 91 matched with the horn-shaped transition section 12, and the convex position of the convex block 91 points to the horn-shaped transition section 12. When the surgical cannula 11 moves in the direction of the guide tube 3, the surgical cannula 11 drives the claw 9 and the end cover 8 to move towards the inner side of the balloon 1, the convex block 91 is separated from the transition section 12, and the movement of the surgical cannula 11 is not blocked; on the contrary, when the operation cannula 11 is withdrawn towards the direction of the ingress pipe 2, the operation cannula 11 drives the claw piece 9 and the end cover 8 to move outwards, at the moment, the convex block 91 is blocked by the transition section 12, the transition section 12 extrudes the inner end of the claw piece 9 to enable the inner end of the claw piece 9 to deviate towards the operation cannula 11, and the operation cannula 11 is held to enable the claw piece 9 to be unable to move, so that the purpose of stopping the backstop is achieved. When the surgical cannula 11 is detached, the surgical cannula 11 can be smoothly extracted from the ingress pipe 2 only by pressing the end cover 8 with one hand to keep the end cover at the inner dead point position and the claw piece 9 is not moved along with the surgical cannula 11.
