As shown in fig. 1, the present embodiment provides a ligation device for assisting cervical polyp removal, at least comprising: the body comprises a working part 1 and a handheld part 2 which are connected, the handheld part 2 can drive the working part 1 to reach the position of the root of a polyp, and the working part 1 is provided with a cavity 3 which can be communicated with the region where the polyp is located and the outside of the body; the fixing piece 5 is arranged on the working part 1 and is positioned in the cavity 3, the fixing piece 5 can fix the ligature rope 4 wound with the coil 6 in the cavity 3, and the cavity 3 allows two ends of the ligature rope 4 to extend out of the body through the cavity 3, so that the coil 6 is tightened when the two ends of the ligature rope 4 are pulled out of the body, and the root of the meat is fastened after the coil 6 is separated from the fixing piece 5. For example, the working portion 1 may have a ring-like or tubular structure.
The ligation device for assisting cervical polyp removal provided by the embodiment can send the working part 1 into the root position of the polyp through the handheld part 2, and can pull the two ends of the ligature rope 4 outside the body to tighten the coil 6 of the ligature rope 4 positioned in the cavity 3, so that the root of the polyp is tightened; moreover, under the effect of the fixing piece 5, the ligature rope 4 can be prevented from moving in the process of being sent into the body and in the earlier stage of dragging the ligature rope 4, and accurate ligation is facilitated. So set up, avoided operating in the vagina, prevent that the operation is failed to draw down the polyp, avoid the polyp directly to drag down the back broken end and retract into the cervical canal in be difficult to hemostasis, avoid the bleeding that dribbling is inexhaustible after the operation to reduce the risk of abortion.
For example, the working portion 1 has an annular structure, and an inner ring region of the annular structure forms a cavity 3; the fixing member 5 is provided on the inner ring wall of the annular structure. Preferably, a plurality of fixing pieces 5 are arranged along the circumferential direction of the inner ring of the annular structure at intervals, and the plurality of fixing pieces 5 are respectively adapted to different positions on the coil 6 so as to limit the coil 6 to a position parallel to the plane where the annular structure is located, and prevent the root of the polyp from being tied up after the coil 6 is tilted. For example, three to four such fixtures 5 may be provided. For example, the whole annular structure can be made of plastic, and the size of the annular structure can be designed according to actual needs, and is not particularly limited herein. For example, the two ends of the coil 6 on the ligature 4 may be wound and knotted, and the knots may be conventional surgical knots to ensure that the coil 6 is tied once.

So arranged as to draw the tying rope 4 from outside the body to tighten the loops 6.
For example, the surfaces of the first guide wheel 7 and the second guide wheel 8 are provided with wire grooves suitable for limiting the swing of the ligature rope 4, so that the ligature rope 4 can be prevented from falling off the first guide wheel 7 or the second guide wheel 8 during traction.
Preferably, the first guide wheel 7 and the second guide wheel 8 are arranged at 180 degrees apart, so that traction force can be more uniform, and the tightening effect of the coil 6 is better.
The hand-hold part 2 is a rod-shaped structure, one end of the rod-shaped structure is connected with the annular structure, and the other end of the rod-shaped structure extends along the axial direction of the annular structure. For example, the number of the hand-held parts 2 may be one or two. For example, the hand-holding part 2 may be made of plastic, so as to reduce the cost, and the size of the hand-holding part 2 may be designed according to the actual needs, which is not particularly limited herein.
The ligation device for assisting cervical polyp removal can flexibly select different types of lines, and has good applicability.
Wherein, can set up spacing ring 9 on the loop configuration, perhaps set up spacing hole isotructure in a certain position on the loop configuration, the tip of ligature rope 4 passes spacing ring 9 or spacing hole earlier before winding up first leading wheel 7 or second leading wheel 8, can be with ligature rope 4 low like this, avoid ligature rope 4 between coil 6 and the leading wheel to the inclination of coil 6 too big for the coil 6 to coil 6 takes place to warp the phenomenon when preventing to pull ligature rope 4, influences ligature's precision. For example, the contact points of the components with the ligature rope 4 may be smoothed to reduce friction during traction.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the utility model.
