The clamp 4 may be a clamp structure of a conventional stone surgical device, and is not limited or described herein.
In the operation process, after the clamp 4 is close to the calculus, the air bag 3 is inflated to expand the air bag 3 and open the urethra, so that the calculus can be conveniently moved after being clamped by the clamp 4. Meanwhile, when the clamp 4 clamps the calculus and moves backwards, the air bag 3 is of a flexible structure, the clamp 4 can drive the calculus to move together and extrude the air bag 3 to deform, and finally the air bag 3 can semi-wrap the clamp 4 and the calculus; at this point, the air bag can deflate.
In getting the calculus clamp and outwards pulling the in-process of taking out, because the calculus outside is half wrapped up by gasbag 3, utilize gasbag 3 to wrap up the outside of calculus, like this, at the in-process that the pulling calculus took out from the urethra, the calculus does not with urethra direct contact, can effectually reduce the urethra by the calculus fish tail to the reduction is to the damage that the patient caused.
Wherein, the free end of the handle 1 is provided with a first finger ring 101, two sides of the slide block 11 are respectively provided with a second finger ring 102, the operator inserts the thumb into the first finger ring 101, and the middle finger and the index finger are respectively inserted into the corresponding second finger rings 102.
Further, in order to facilitate the inflation treatment of the balloon 3 during the operation, an air inlet pipe 13 communicated with the sheath pipe 2 is arranged on the handle 1, and the air input from the air inlet pipe 13 is filled into the balloon 3 through the sheath pipe 2.
Specifically, an external medical air supply source outputs air through an air inlet tube 13, and the air is transmitted into the balloon 3 via the sheath tube 2, so that the balloon 3 is inflated in the urethra. And for the air inflow, the air inflow is controlled according to the size of the calculus in the actual operation process, so that the clamp 4 can clamp and move the calculus, and the limitation is not made.
Further, in order to connect the balloon 3 between the sheath 2 and the clamp 4, the balloon 3 is provided with connecting tubes 31 at both ends, respectively, one of the connecting tubes 31 is connected to the sheath 2, and the other connecting tube 31 is provided with the clamp 4.
Specifically, the airbag 3 is generally made of a flexible material such as silica gel, the connecting pipe 31 can be made of a hard plastic, the airbag 3 is integrally formed with the connecting pipe 31 during processing, and then the airbag is connected with the sheath tube 2 and the clamp 4 through the connecting pipe 31.
