As shown in fig. 1 to 3, a puncture rotary-cut suction device capable of automatically rebounding when a hard object occurs in an operation includes a suction tube 1 and a rotary-cut tube 2, wherein the head of the suction tube 1 is an inclined opening 10, and the head of the rotary-cut tube 2 is provided with a plurality of cutting teeth 20; the rotary cutting tube 2 is sleeved in the suction tube 1, the head of the rotary cutting tube 2 is telescopic in an inclined plane opening 10 of the suction tube 1, one end of the tube body of the rotary cutting tube 2 is provided with a strip-shaped groove 21 along the axial direction of the rotary cutting tube 2 on the surface of the tube body of the rotary cutting tube 2, at least two sections of the strip-shaped groove 21 are arranged, the strip-shaped grooves 21 are symmetrically arranged on the surface of the rotary cutting tube 2, the surface of the tube body of the rotary cutting tube 2 is also provided with a curved surface groove 22, the curved surface groove 22 is arranged between the two strip-shaped grooves 21, the head and the tail of the curved surface groove 22 are sequentially communicated with the head and the tail of the two strip-shaped grooves 21, and the curved surface grooves 22 are symmetrically arranged on the surface; the inner wall of the suction tube 1 is provided with a boss 3, the boss 3 slides in a strip-shaped groove 21 and a curved groove 22, the end part of the rotary cutting tube 2 is sequentially connected with a rotary ring 4, a spring 5 and a fixed cylinder 6, the rotary ring 4 rotates relative to the end part of the rotary cutting tube 2, the spring 5 is fixed between the rotary ring 4 and the fixed cylinder 6, and the fixed cylinder 6 is fixed on the inner wall of the suction tube 1; the periphery of the surface where the inclined plane opening 10 is located is provided with a trigger button 7, and the trigger button 7 is externally connected with an induction protection device along the inner wall of the suction tube 1 through a lead.

When medical personnel operate the suction tube 1, the rotary cutting tube 2 sleeved in the suction tube 1 can remove thrombus and breeding matters near tissues, simultaneously the suction tube 1 sucks contents in a human body, the operation is clear, the pollution chance is reduced, the tail part of the suction tube 1 is provided with a pressure device, after negative pressure is generated, the contents in the human body enter the suction tube 1 under the action of the negative pressure, before the suction tube 1 sucks the contents, the rotary cutting tube 2 is firstly needed to cut the periphery of the human body tissues needing to be sucked so that the suction tube 1 enters the work to achieve the function of matching work, when the rotary cutting tube 2 cuts and touches hard objects, mutual acting force is generated between the hard objects and the rotary cutting tube 2, the tail part of the rotary cutting tube 2 is provided with a strip-shaped groove 21 and a curved groove 22, at the moment, the curved groove 22 moves relatively along a boss 3 of the suction tube 1 under the action of force, the path of the relative movement of the boss 3 is: the rotary cutting pipe 2 rotates from top to bottom along the curved groove 22 and rotates relative to the rotary ring 4 to avoid interference. After the relative rotation for half a circle, the boss 3 makes relative ascending movement to recover the original point through the elastic force action of the spring 5, so that in the operation, when the rotary cutting tube 2 contacts a hard object, the rotary cutting tube cannot resist the hard object all the time, the hard object (bone) cannot be stabbed, and the protection effect is achieved. The fixing cylinder 6 is used for fixing and limiting, and the rotary cutting tube 2 is prevented from falling out of the suction tube 1. Attract pipe 1 in the art of cooperation rotary cutting pipe 2, attract trigger button 7 on 1 inclined plane opening 10 of pipe is touching hard thing (skeleton) in the human body, and hard thing (skeleton) drive trigger button 7 switches on, and trigger button 7 passes through the wire with information and transmits to external response protection device on, and medical personnel make the judgement through observing the signal indication that response protection device sent this moment, promptly: the whole rotary cutting suction device is properly pulled out towards the outside of the body through manpower or medical auxiliary instruments, or the rotary cutting part of the rotary cutting suction device is adjusted, and the working path of the rotary cutting suction device is repositioned, so that secondary injury in the operation of a patient is avoided, and equipment can be protected.

As shown in fig. 2, the length of the strip-shaped groove 21 is stopped in the rotary-cut tube 2, and the depth of the strip-shaped groove 21 is the same as that of the curved groove 22; ensures the smooth relative movement of the boss 3 in the strip-shaped groove 21 and the curved groove 22,

the number of turns of the spring 5 is 8-10; the elastic force is enough, if the number of turns is too much or too little, and in the case of too little, the elastic force is insufficient and unstable. And elastic fatigue is easy to occur; because the acting force when the cutting teeth 20 of the rotary-cut tube 2 contact hard objects is relatively small in the operation, if the number of turns is too large, the elastic force is too large, and the rotary-cut tube 2 can not realize retraction movement.

The diameter of the boss 3 is smaller than or equal to the width of the strip-shaped groove 21 and the curved surface groove 22; also ensures smooth movement of the boss 3 in the strip-shaped groove 21 and the curved groove 22.

The curved groove 22 is connected from the tail of one of the strip-shaped grooves 21 to the head of the other strip-shaped groove 21; a curved groove 22 is formed between the two strip-shaped grooves 21, and the curved groove 22 is arranged at the upper right and the lower right, so that the boss 3 can be ensured to float up and down in the curved groove 22 in a relative motion manner to reach an optimal state, that is, the telescopic distance of the rotary cutting pipe 2 is longer.

The curved surface of the curved surface groove 22 is a smooth arc surface; the interference and the clamping phenomenon when the boss 3 contacts with the surface of the curved surface groove 22 are avoided.

The head and tail surfaces of the strip-shaped groove 21 are in cambered surface transition; the smoothness of the relative movement of the boss 3 is better.

The trigger buttons 7 are enclosed on the surface of the suction tube 1 where the inclined plane opening 10 is located, and at least four trigger buttons 7 are arranged; the trigger button 7 is also provided with a rubber layer 8, and the rubber layer 8 is coated on the trigger button 7 and connected to the suction tube 1; at least four trigger buttons 7 are arranged and are enclosed on the inclined plane opening 10, so that the trigger buttons 7 can be switched on when the surfaces of different positions on the circumference of the suction tube 1 are in contact with hard objects in the body, and the rubber layer 8 is used for reducing the uncomfortable feeling of the trigger buttons 7 in contact with the body.

The above description is for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way, and modifications and variations can be made without departing from the principles of the present invention.
