Tissues such as arachnoid, tumor envelope, blood vessel and the like need to be cut off in neurosurgery, particularly, in neurosurgery under an endoscope, the operation relates to deep brain tissues, the space is narrow, the channel is long and narrow, the action difficulty of the traditional microscissors is high, and the action space needed after the scissors are crossed is large. In the working channel with radian, the traditional scissors or microscissors can not be unfolded to work effectively at all. This places new demands on scissors in neurosurgical curved working channel procedures.
Secondly, department surgeons such as neurosurgery discover that the existing microscissors have the following defects in long-term operation experience: (1) the longer and longer the gun-shaped arm of the scissors or microscissors requires a larger operating space. (2) The opening arm of the microsciscope is long, only the opening with the front end of about 1-1.5mm is used for shearing in deep brain tissue, and the opening redundancy is too large. (3) The endoscope operation needs frequent replacement of medical instruments, thereby delaying the operation time; in the process of replacing medical instruments, the vision of a surgeon is separated from the surgery, so that the risk of mistaken injury is caused. (4) In the time of replacing the aspirator with the microscissors, the new bleeding covers the original bleeding part, which causes difficulty in the continuous operation. (5) Cannot pass through the arc-shaped working channel. These problems have long been limiting for surgeons such as neurosurgery, and a new soft hydraulic micro-scissors is needed to solve these problems.
