Detailed Description

For a better understanding of the present invention, reference will now be made in detail to the accompanying drawings.

Example 1

As shown in fig. 1, a pair of microscissors comprises a handle part 1, a fixed conduit part 2, a movable conduit part and a force application part. The fixed conduit part 2 is fixedly arranged on the handle part 1. The movable conduit part is installed on the fixed conduit part 2. The force application part is respectively connected with the handle part 1 and the movable conduit part. The fixed conduit part 2 has one closed end and the other open end. In actual use, a hose can be used to connect and fix the open end of the conduit part 2 and the negative pressure device. The fixed pipe part with one closed end is provided with a shearing blade hole 20, and the movable pipe part and the fixed pipe part 2 form relative movement by pressing the force application part, so that shearing action is completed at the shearing blade hole 20. By adopting the shearing mode and the force application mode, the utility model is convenient and safe, and can achieve good instantaneous shearing effect by small-amplitude pressing, thereby relieving the pain of patients. During application, the sheared lesion tissue is sucked out by the negative pressure device along the catheter.

Specifically, the handle portion 1 is provided with a fixed conduit connecting block 12, and the movable conduit portion includes a movable conduit connecting block 31 and a movable conduit 30. The urging portion includes an urging block 40 and a return spring 41. The movable conduit 30 is sleeved outside the conduit of the fixed conduit part 2, and the return spring 41 is arranged between the fixed conduit connecting block 12 and the movable conduit connecting block 31. Shearing is accomplished by the return action of return spring 41. When the cutting tool is used, a user holds the handle 1 with a hand and presses the force application block 40 to contract the return spring 41, so that energy is accumulated, and pushes the movable catheter connecting block 31 and the cutting blade hole 20 to be exposed, and after the lesion tissue enters the cutting blade hole 20, the force application block 40 is released, so that the energy accumulated in the return spring 41 is released, and the movable catheter connecting block 31 is pushed, and the cutting operation is completed at the cutting blade hole 20. The cut lesion tissue is sucked out along the fixed catheter part 2.

Specifically, a fixed conduit screw hole is formed in the fixed conduit connecting block 12, and the screw 5 penetrates through the fixed conduit screw hole to fix the fixed conduit part 2 on the fixed conduit connecting block 12. The movable guide pipe connecting block 31 is provided with a movable guide pipe screw hole, and the screw 6 penetrates through the movable guide pipe screw hole to fix the movable guide pipe 30 on the movable guide pipe connecting block 31. This configuration facilitates the reuse of the apparatus, and the fixed conduit part 2 and the movable conduit 30 can be attached or detached by tightening or loosening the

screws

5, 6. Thus, except the fixed conduit part 2 and the movable conduit 30, other parts can be reused, and the cost is reduced.

Specifically, the front of the handle part 1 is provided with a bracelet 10, and the rear of the handle part 1 is provided with a hose groove 11. The setting of bracelet 10 is convenient for the user and is held equipment tightly, and the setting of hose groove 11 is convenient for imbed the hose in hose groove 11 at practical application in-process, has just so reduced the hose and has operated the in-process to doctor's influence. The end of the movable conduit part used in cooperation with the shearing blade hole 20 is provided with a blade. The design is beneficial to quickly cutting off the pathological tissue, and the operation is easier for a doctor.

Example 2

As shown in fig. 2, the difference from embodiment 1 is that the handle portion 1 is provided with a fixed catheter connecting block 12 in this embodiment. The movable pipe portion includes a movable pipe connecting block 31 and a movable pipe 30. The urging portion includes an urging block 40 and a return spring 41. The movable conduit 30 is sleeved in the conduit of the fixed conduit part 2, and the return spring 41 is arranged between the force application block 40 and the fixed conduit connecting block 12. In actual use, the sheared lesion tissue is sucked out from one end of the movable catheter 30.

The above detailed description is not to be considered as limiting the invention, and insubstantial changes from the disclosure herein may be made by those skilled in the art without departing from the scope of the invention.
