Detailed ways

The present invention will be described in further detail below in conjunction with accompanying drawings 1-4.

Example: A minimally invasive lithotripsy device for removing stones during laparoscopic cholecystectomy, as shown in Figures 1 to 4, includes a side plate 1 and a holding tube 2, the side plate 1 is provided with two pieces, and the holding tube 2 One end of one end stretches between the two side plates 1, and the handle tube 2 is fixedly installed with a connecting rod 1 between the outer wall of the part of the two side plates 1 and the two side plates 1, and the handle tube 2 does not extend into The outer wall of the part between the two side plates 1 is depicted with anti-slip lines 18, the setting of the anti-slip lines 18 can prevent the holding tube 2 from slipping when the medical personnel hold the holding tube 2.

Grip tube 2 is equipped with cylinder body-4 that both ends pass through the handle tube 2, cylinder body-4 can slide in the handle tube 2, one end of cylinder body-4 is equipped with rack-5, and the other end is equipped with handle- 6. Two clamping arms are installed between the two side plates 1. The clamping arms include a fixed plate 7, a movable plate 8 and a clamping plate 9. The inner wall of the clamping plate 9 is fixedly equipped with a clamping pad 15, and the clamping pad 15 is used to increase the frictional force between the device and the calculus, so as to avoid slipping when the calculus is clamped.

One end of the fixed plate 7 is arranged in an arc shape and is equipped with a rack two 10 engaged with the rack one 5, and one end of the fixed plate 7 equipped with the second rack 10 is hinged between two side plates 1, that is, the fixed plate 7 can be Rotate around the hinge, between the movable plate 8 and the fixed plate 7 and between the clamping plate 9 and the movable plate 8 are all elastic hinges. displayed status.

A cylinder body two 11 with one end extending out of the cylinder body one 4 is installed in the cylinder body one 4, the cylinder body two 11 can slide along the cylinder body one 4, and the end of the cylinder body two 11 protruding out of the cylinder body one 4 is clamped close to the movable plate 8 A connecting rod two 12 is installed between one end of the plate 9, and the two ends of the connecting rod two 12 are hinged with the movable plate 8 and the cylindrical body two 11 respectively.
