(4) the uterine clamp 4 is extended from one end of the electric handle 1 into and through the cutter head part of the excision cutter tube 2.
In the step (3), when the operation button 7 is pressed, the cutting knife tube 2 and the suction tube 3 are flush with each other at the end; when the operation button 7 is released, the end of the excision knife tube 2 extends outside the suction tube 3.
The working principle of the invention is as follows: when the invention is used, an operator firstly inserts the puncture cannula to establish a working channel, then stretches the excision device into the uterus of a patient through the puncture cannula, and grabs the tissue to be excised through the uterine grasper 4. The electric handle 1 is driven to act through the key after the uterine cramp 4 is grabbed, so that the driving part 5 drives the excision knife tube 2 to rotate, and the uterine cramp 4 is controlled to contact tissues with the knife head part of the excision knife tube 2 to form cutting, so that the tissues are separated from organs after cutting.
When the excision knife tube 2 is cut, the end of the aspiration tube 3 and the knife head are dislocated from each other in a natural state, and the knife head is exposed. When the excision knife tube 2 is in contact with an external organ, an operator can press the operation button 7 to enable the sliding seat 13 to transversely move and drive the lifting rod 12 to move upwards through the connecting rod 122; after the lifting rod 12 moves upwards, the brake block 121 and the transmission inclined plane 602 move relatively and drive the transfer ring 6 to move transversely, so that the transfer ring 6 overcomes the elastic piece 11 and drives the suction pipe 3 to move outwards. When the adapter ring 6 moves to the position that the slider 601 and the electric handle 1 are mutually attached at the joint surface 10, the end part of the suction tube 3 and the cutter head part of the excision knife tube 2 are mutually flush, and the sealing ring 16 and the positioning ring 17 are mutually attached, so that the excision knife tube 2 is wrapped, and the excision knife tube 2 is prevented from being contacted with external organs. Meanwhile, the operation button 7 triggers the suction device to act through the micro switch after being completely pressed, so that the liquid suction channel 8 can perform negative pressure suction on accumulated blood at the cutter head part, and the suction stability of the accumulated blood is ensured by matching with the sealing after the sealing ring 16 and the positioning ring 17 are tightly attached. When the suction tube 3 interferes with the cutting operation after wrapping, the operator can also release the operation button 7 accordingly and control the suction tube 3 to retract to the designated position, thereby improving the control effect on the suction tube 3.
When in actual use, an operator can control the excision device to carry out excision and suction operations at the same time as required, and can also independently control the excision device and can finish the excision operation and suction operations through one hand, so that compared with the existing electric excision device, the operation complexity and the control difficulty of the operator are not increased under the condition of improving the functionality, and meanwhile, the occupied space of the excision device in uterus is not increased, and the applicability and the actual use effect of the excision device are improved.
