Abstract

The invention discloses a retractor for neurosurgery, which comprises four connecting tubes, four connecting tubes and an adjustment mechanism. connected in turn to form a closed rectangular frame; the adjustment mechanism includes a first rotating shaft, a first rack and a first gear, the first gear is sheathed and fixed on the first rotating shaft, the first rack is arranged in the first guide groove, Both ends of the first rack extend into the connecting cylinder, the first rack is meshed with the first gear, one end of the first rotating shaft is inserted into the connecting pipe, and the other end is arranged outside the connecting pipe. The retractor for neurosurgery drives the first rack and the second rack to move in the first guide groove and the second guide groove respectively by rotating the first rotating shaft, so that the end of the connecting tube is in the connecting cylinder Sliding, according to the size of the wound, freely adjust the distance between two adjacent connecting tubes to adapt and fix the wound.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary tools, in particular to a retractor for neurosurgery. Background technique [0002] Neurosurgery is the application of unique neurosurgery research methods to study the human nervous system, such as the brain, spinal cord and peripheral nervous system, as well as its related subsidiary organs, such as the skull and scalp, on the basis of surgery as the main treatment method. , cerebrovascular meninges and other structural damage, inflammation, tumors, deformities and certain genetic metabolic disorders or dysfunctional diseases. [0003] Existing neurosurgery often needs to use retractors during the operation, but most retractors cannot adjust the appropriate size according to the size of the patient's wound, and often use several different retractors. The process of using like this is comparatively troublesome, can not improve quickness and sensitive effect of doctor's operation. More...
