Among them: 1—Handheld end, 2—Pliers head, 3—Pliers arm, 4—Finger ring, 5—Hinge shaft, 6—Elbow, 7—Hook type tip, 8—Clamping part, 9—Scratches.

Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

As shown in Figures 1 and 2, the gallbladder stone removal forceps comprises a hand-held end 1, a pliers head 2 and a pliers arm 3, the hand-held end 1 is provided with a finger ring 4, and the pliers arms 3 are connected by a hinge shaft 5, and the An elbow 6 is connected under the hand-held end 1, the arc of the elbow 6 is 15-20°, the finger ring 4 and the hand-held end 1 are engaged, and the pliers head 2 is provided with a hook-shaped pointed head 7, The hook-shaped pointed head 7 is misplaced, and there is a clamping part 8 under the hook-shaped pointed head 7. When working, when a large stone is encountered, because the finger ring and the forceps arm are engaged, it can be easily disassembled. For the lower finger ring, the operator uses the elbow on the forceps arm to lift, with strong adhesion, which can effectively remove larger stones. The hook-shaped tip can easily pick the stones inside the gallbladder to a suitable position, which is convenient for taking out the stones. The structure is reasonable, practical and convenient, and suitable for popularization and use.

The hook-shaped pointed head 7 is misplaced, and can be matched with each other when not in use. When there is a stone located in a difficult-to-reach position in the gallbladder, the hook-shaped elbow can be used to slowly pick it out, and then use the clamping part to pick it out. Clamp out the stone.

It is worth noting that the clamping part 1 is circular, the clamping part is circular, beautiful and convenient to clamp, suitable for stones of various shapes, the diameter of the clamping part 1 is 3-5cm, the clamping Scratches 9 are engraved on the part 1, and the scratches 9 are wave-shaped. The scratches make the clamped stones not easy to slip, and the wave-shaped makes the clamping force of the clamping part stronger, which is suitable for use in the utility model.

In addition, the thickness of the clamping portion 8 can be determined according to actual needs, and the curvature of the elbow 6 can also be set according to the needs of the hospital.

Based on the above, when encountering a large calculus during work, the ring can be easily removed due to the snap connection between the ring and the forceps arm, and the operator can use the elbow on the forceps arm to lift the stone, which has strong adhesion and can be removed effectively For larger stones, the hook-shaped pointed tip can easily pick the stones inside the gallbladder to a suitable position, which is convenient for taking out the stones. It has a reasonable structure, is practical and convenient, and is suitable for popularization. For stones of various shapes, the scratches make the clamped stones not easy to slip, and the wave shape makes the clamping force of the clamping part stronger, which is suitable for use in the utility model.
