Surgical instrument
The invention relates to the technical field of medical instruments, discloses a surgical instrument, and particularly relates to a shapeable surgical instrument suitable for single-port endoscopic surgery, which comprises an inner rod assembly, an outer rod assembly and a handle assembly. The outer rod assembly is made of annealed metal (such as pure copper or copper alloy), can be shaped by hands and is kept in a bent form; the inner rod is a nickel-titanium alloy multifilament or a stranded rope, and low-resistance rotation in a bending state is achieved. The handle rotating wheel drives the inner rod to rotate and is matched with the axial push-pull of the rear handle, so that the 360-degree real-time angle adjustment and opening and closing actions of the working part (forceps piece / scissors) are controlled by a single hand, and the forceps piece / scissors do not need to be taken out of a body. The problems that a traditional straight rod instrument cannot reach a narrow area, a pre-bending instrument cannot be adjusted in an operation, and an existing shaping instrument needs in-vitro angle adjustment of two hands are solved, the operation efficiency is improved, and the cleaning and sterilizing time is shortened.

A surgical instrument
This invention relates to the field of medical device technology and discloses a surgical instrument, particularly a malleable surgical instrument suitable for single-port laparoscopic surgery, comprising an inner rod assembly, an outer rod assembly, and a handle assembly. The outer rod assembly is made of annealed metal (such as pure copper or copper alloy), which can be hand-shaped and maintain a bent shape; the inner rod is made of nickel-titanium alloy multifilament or stranded rope, enabling low-resistance rotation in a bent state. The inner rod is rotated by a handle wheel, and in conjunction with the axial push-pull of the rear handle, 360° real-time angle adjustment and opening / closing of the working part (clamps / scissors) can be achieved with one hand, without the need for removal from the body. This invention solves the problems of traditional straight rod instruments being unable to reach narrow areas, pre-bent instruments not being able to be adjusted intraoperatively, and existing malleable instruments requiring two hands for external angle adjustment, thus improving surgical efficiency and shortening cleaning and sterilization time.
