Problems solved by technology
[0003] However, the operator and the assistant often need to cooperate for a long time to cooperate tacitly. If the assistant is absent, the operation cannot be completed. If the assistant is a novice or does not have a tacit understanding with the operator, the efficiency of stone setting will be significantly reduced, and the operation time will be significantly prolonged. The patient's pain and complication rate. In addition, the area where the operator stands is small during the operation. The operator and the assistant standing in the operation area at the same time will hinder each other. The person completes the control of the mirror body and the control of the stone-net basket. At this time, it is necessary to provide a controller for the stone-net basket applied to the flexible ureteroscope.

The invention discloses a spiral stone dislodger controller applied to a flexible ureteroscope. The spiral stone dislodger controller comprises a fixed bracket, a handle telescopic rod, a gear and rack transmission mechanism, an elastic member and a trigger, wherein the free end of the handle telescopic rod is connected with a spiral stone dislodger; the gear and rack transmission mechanism comprises a first rack, a first gear, a second gear and a second rack; a positioning protrusion is fixedly arranged on the second rack; one end of the elastic member is fixedly connected with a positioningprotrusion; and the trigger penetrates through the fixed bracket to be fixedly connected with the first gear. According to the spiral stone dislodger controller disclosed by the invention, the handletelescopic rod, the gear and rack transmission mechanism, the elastic member and the trigger are used to control the opening or the closing of the spiral stone dislodger, one-man operation of operators is realized, and labor force is reduced; and the spiral stone dislodger controller disclosed by the invention is simple in structure, and easy to realize, the surgery time can be shortened, the painof patients can be alleviated and the surgery efficiency can be improved.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a stone-net basket controller applied to flexible ureteroscopes. Background technique [0002] Ureteroscopic stone extraction is suitable for patients with upper ureteral stones and renal pelvis calculi. During the operation, the operator finds stones by operating the flexible ureteroscope. When operating the flexible ureteroscope, the operator needs to hold the mirror body with both hands. One hand holds the handle to control the push rod to control the bending direction of the mirror body. The long mirror body controls the length of the mirror body into the body, and then the assistant puts the stone basket, and controls the opening or closing of the stone basket to grasp the stone and take it out of the patient's body. [0003] However, the operator and the assistant often need to cooperate for a long time to cooperate tacitly. If the assistant is absent, the operatio...
