[0002] Minimally invasive surgery is currently the main research hotspot in surgical treatment, and often requires one instrument to achieve multiple functions. However, current instruments, such as endoscopic tumor dissection surgery, require the use of multiple instruments such as injection needles, electrocoagulators, and ligation devices. They have single functions and complex operating steps, and require the replacement of multiple instruments.

[0003] Urological surgery refers to surgical procedures that treat urinary system diseases. The urinary system includes organs such as the kidneys, ureters, bladder and urethra. Common urological surgeries include ureterolithotomy, ureteral end-to-end anastomosis, urethral stricture incision, etc. Currently, many clinical diseases require bladder injections through the urethra. The scope of application of urological surgical instruments is also gradually extending. New technologies that require bladder injections, biopsies, and other treatments are also being gradually developed. However, the current routine basic steps are to use a bladder injection needle to complete the bladder injection first, and then replace other surgical equipment such as an electrosurgical ring to perform steps including cutting and hemostasis.

[0043] When shearing is required, the sliding handle 302 is moved backward, the spring 6 is stretched, the sliding handle 302 moves backward, driving the cable 9 to move backward, and the cable 9 moves backward to drive the second blade 102 to rotate, so that the front end of the second blade 102 gradually approaches the first blade 101 to achieve a cutting effect, and the blade assembly 1 is an oblique scissors with a shearing function when it is opened, and the cutting function can be achieved by controlling the movement of the sliding handle 302.

[0044] Moreover, the first outer tube 201 is bendable, including the conductive wire 8, the guide tube 14, and the pull rope 9 passing inside, which are all movable structures. When the entire first outer tube 201 is bent and moved, its internal components can move in a coordinated manner to achieve multi-angle conversion. The conductive wire 8 is connected to the second blade head 102 to achieve electrocoagulation and hemostasis during the operation; the first blade head 101 is engraved with scales to achieve drug injection during the operation. At the same time, the thickness of the bladder wall can be observed to avoid excessive penetration and injuring other adjacent organs such as the intestines.
