Problems solved by technology

However, the current domestic minimally invasive medical cutting wires are generally not soft enough, and doctors need to use a lot of force during the operation, which can easily cause physical discomfort to patients, and more importantly, increase the difficulty of the operation
Moreover, during the operation, the two ends of the medical steel wire are easily scattered, which makes this section of medical minimally invasive cutting wire unusable, because both ends of the wire cannot be smoothly introduced into the patient's body.

Abstract

The invention discloses a wire-like element which comprises, by weight, 65-75 parts of Fe, 15-20 parts of Cr, 9-12 parts of Ni and 9-19 parts of C. The invention further discloses a medical minimal invasive cutting line which comprises a core wire, wherein the core wire comprises a plurality of intertwined wire-like elements with smooth surfaces. The invention further discloses a method for manufacturing the medical minimal invasive cutting line which includes the step: knitting a plurality of intertwined wire-like elements with the smooth surfaces in an interweaving manner to form the core wire. The wire-like element is good in strength and extensibility and excellent in toughness and flexibility, the core wire knitted by the wire-like element serves as the medical minimal invasive cutting line and has excellent flexibility and enough thinness, spiral springs are arranged at two ends of the medical minimal invasive cutting line, so that two ends of the core wire cannot be dispersed, functions cannot lose, and the problems of insufficient softness and easy dispersion of two ends of an existing minimal invasive cutting line are solved.

Description

technical field [0001] The invention belongs to the field of minimally invasive surgery consumables, and relates to a filamentous element, a medical minimally invasive cutting wire and a manufacturing method thereof. Background technique [0002] In minimally invasive operations such as carpal tunnel cutting, braided medical consumables such as medical steel wires are introduced into the carpal tunnel and cut. When the medical minimally invasive cutting wire or other consumables enter the patient's body, it is very important that the medical minimally invasive cutting wire is soft enough, has sufficient cutting effect, and sufficient toughness, etc. This has a great impact on the patient's health. If the performance of the medical minimally invasive cutting wire is good, it will firstly reduce the difficulty of the doctor's operation, shorten the operation time, and reduce the patient's physical pain. Second, the medical minimally invasive cutting wire with excellent perform...
