Problems solved by technology

[0005] To sum up, the problem existing in the prior art is: the existing lumbar retractor generally pulls away from the body of the retractor. Pulling in this way may expand the range on both sides of the incision, resulting in increased bleeding. conducive to surgery

Abstract

The invention belongs to the technical field of medical treatment and discloses a lumbar three-direction minimally invasive retractor. Displacement detectors embedded on retractable pulling hooks areused for detecting a pulling distance through an improved two-dimensional Peierls-Nabarro dislocation model; detected data are transmitted to a control center; after comparing the detected data with built-in parameters for analysis, the control center transmits a control instruction to a data processing module on a motor, and the pulling distance of the retractable pulling hooks is controlled according to the processed data. According to the lumbar three-direction minimally invasive retractor, the three-direction retractable puling hooks are adopted; through automatic adjustment and fine adjustment, the range size of both sides of an incision is fixed, the amount of bleeding of a patient is decreased, convenience is provided for doctors during surgery while the pain of the patient is relieved, the operation time is shortened, and the operation efficiency is improved.

Description

technical field [0001] The invention belongs to the field of medical technology, in particular to a lumbar three-way minimally invasive retractor. Background technique [0002] Retractors, also known as retractors, are used to retract tissues and expose the surgical field for easy exploration and operation. They can be divided into two types: hand-held retractors and automatic retractors. There are various specifications of different shapes and sizes, and the appropriate retractor can be selected according to the operation needs. Existing lumbar retractors generally pull apart the retractor body. Pulling in this way may expand the range on both sides of the incision, resulting in increased bleeding, which is not conducive to the operation. [0003] With the increasing development of the Internet today, smart devices have gradually penetrated into our lives. These smart devices make our lives more efficient and convenient. [0004] On existing minimally invasive retractors,...
