The specific embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

1 to 4, including the handle 1 in the up and down direction, the lower end of the handle 1 is respectively provided with baffles 2 on both sides, and a clamp is arranged between the two baffles 2, and the clamp includes a left jaw 3 and a right The clamping jaw 4, the middle part of the left clamping jaw 3 and the right clamping jaw 4 are hingedly connected to the baffle plate 2 through the pin shaft 5 respectively, the lower end of the clamp extends out of the baffle plate 2, and the handle 1 is provided with a through groove 6 that runs through up and down, and the through groove 6 A sliding rod 7 is slidably connected between the left clamping jaw 3 and the right clamping jaw 4 . The lower end of the sliding rod 7 is provided with a blade 8 , and the lower end of the clamp can be clamped with the rising of the sliding rod 7 .

In order to clamp the lower end of the clamp with the rise of the sliding rod 7, the upper ends of the left clamping jaw 3 and the right clamping jaw 4 are respectively connected to the front and rear axial rollers 9 in rotation, and the left and right sides of the sliding rod 7 are respectively provided with rollers 9 located below the rollers 9. The trapezoidal block 10, the distance between the upper end of the side of the trapezoidal block 10 away from the sliding rod 7 and the sliding rod 7 is smaller than the distance between its lower end and the sliding rod 7, and the inclined surfaces of the two trapezoidal blocks 10 can be respectively corresponding to the rollers on the side 9 contacts.

In order to open the lower end of the clamp, the left and right sides of the baffle plate 2 are respectively provided with swinging grooves 11 penetrating through the front and rear, respectively. The two swinging grooves 11 are respectively slidably connected with connecting rods 12 in the front and rear axial directions. The ends are respectively fixedly connected with the upper end of the clamp on the corresponding side, and the opposite sides of the front ends of the two connecting rods 12 are connected by a tension spring 13 .

In order to facilitate the up and down movement of the sliding rod 7, the handle 1 is provided with a rectangular groove 14 in the up-down direction and running through its front surface. The rectangular block 15 to which the sliding rod 7 is fixed, the front end of the rectangular block 15 protrudes from the rectangular slot 14 and is provided with a push block 16 .

In order to fix the position of the sliding rod 7, a rack 17 is provided on the left side wall of the rectangular slot 14, a spring sheet 18 that can be inserted into the slot is provided on the upper end of the rectangular block 15, and the push block 16 is provided with an up-down direction and a front-rear direction. A block 20 located above the rectangular block 15 is slidably connected to the through groove 19 , and the block 20 can shield the upper end of the spring sheet 18 .

In order to facilitate the use of the patient, the opposite surfaces of the left gripper 3 and the right gripper 4 are respectively provided with friction blocks 21 located at the lower ends thereof, and both sides of the blade 8 are respectively provided with cutting edges.

When the utility model is in use, the blade 8 is set lower than the clamp, the block 20 is located on the right side of the spring sheet 18, and the position of the sliding rod 7 is fixed;

Use the blade 8 to excise the surrounding tissue of the patient's kidney stone. After the excision is completed, push the block 20 downward so that the block 20 no longer blocks the upper end of the spring sheet 18. At this time, the push block 16 is moved upward, and the push block 16 The rectangular block 15 drives the sliding rod 7 to move upward along the through slot 6, the sliding rod 7 drives the blade 8 to move upward, and the rectangular block 15 drives the spring sheet 18 to move upward. keep swinging left and right;

As the sliding bar 7 moves upward, the sliding bar 7 drives the two trapezoidal blocks 10 to move upward. When the inclined surfaces of the two trapezoidal blocks 10 are in contact with the rollers 9 on their corresponding sides, the blade 8 is higher than the lower end of the clamp, and at this time, through the left clamp The claw 3 and the right clamping claw 4 clamp the kidney stones. As the trapezoidal block 10 moves upward, the trapezoidal block 10 drives the upper end of the clamp to swing outward, and the upper end of the clamp drives the two connecting rods 12 to move along the swing grooves 11 on the corresponding sides respectively.
