Description

technical field

[0001] The invention relates to a retractor, in particular to a disposable brain operation retractor. Background technique

[0002] A retractor in a broad sense refers to a type of medical device that is in contact with human body tissue in order to obtain a surgical field of view and an operating space during a surgical operation. With the development of medical technology, the types and functions of retractors are becoming more and more abundant.

[0003] However, for fine tissues of the human body, such as brain tissue, it is difficult for some retractors to provide good support for the operation. For example, in neurosurgical operations such as ventricular tumors, ventricular hemorrhage, brain subcortical tumors, intracerebral hematoma, and endoscopic surgery, it is difficult to use the existing guide to detect brain tumors and brain tumors located in the deep center of the brain.
