Description

Spine scope minimal access surgery instrument that facilitates use

Technical Field

The utility model belongs to the technical field of the medical treatment, concretely relates to backbone scope for minimal access surgery apparatus who facilitates use.

Background

Surgical forceps are a common surgical instrument used clinically to hold tissue to be treated. However, there are a number of problems in clinical applications: when the clamping force is small, the clamped tissue is easy to slide; if the clamping force is too large, tissue damage is likely to occur. The effective clamping force is obtained on the premise of not causing tissue damage, and the key problem in the safe use of the surgical forceps is solved. Smart materials are materials that can sense environmental stimuli and respond to them with certain smart characteristics. By function, smart materials can be classified into optical fibers, shape memory alloys, piezoelectrics, electrorheological fluids, and electro (magneto) strictive materials, among others. The shape memory alloy is an intelligent material capable of memorizing the original shape, and has super-elasticity property, namely, the mechanical elasticity range of the shape memory alloy is far higher than that of a common material. The shape memory alloy also has good biocompatibility and is widely applied in the biomedical field. By utilizing the superelasticity property of the shape memory alloy, a minimally invasive surgical instrument with intelligent characteristics is developed, so that not only can effective clamping force be obtained, but also human tissues can be protected from being damaged, and the minimally invasive surgical instrument has important scientific significance and application value for clinical surgery.
