217 driving square shaft 218 drive screw rod 219 to rotate, and then drive nut 220 is along 214 linear slide of guide rod, the line of nut 220
Property slide and can drive the main body running part of the second structural bone 104 and the 3rd drive mechanism 207 while doing linear movement, because
This can realize the feed motion of two first structure bones 103 and second structural bone 104 with respect to supporting member 105.
When rotate the 3rd control change 208 when, its can drive gear 223 rotate, square so as to be driven by sleeve 224
Axle 225 drives worm screw 226 to rotate, and then drives worm gear 227 to rotate, and the rotation of worm gear 227 carries movable slider 229 by connecting rod 228
Along 222 linear slide of guide rod, the linear slide of slide block 229 can drive two first structure bones 103 to do linear movement, therefore can
The elevating movement of high-definition camera 101 is enough realized.
When the present invention is applied in operation, the operable cystoscope mirror body 10 through sterilization of surgeon inserts urethra
In, after high-definition camera 101 is stretched out from light-wall pipe 106, rotation wherein controls change 208 to adjust two first structure bones
103 and second structural bone 104 extend out to appropriate length from supporting member 105, then rotate another control change 208 and control
Then the pitching of high-definition camera 101 is rotated the 3rd control change 208 and is driven high-definition camera 101 overall with adjustable visual angle
Enter to give to adjust imaging region further.After the position of high-definition camera 101 is finished with pose adjustment, can be by being arranged symmetrically
Operation tool is inserted in the interface 231 of 202 both sides of sub-shell, to put transurethral urology procedure to good use.
