Abstract

The invention discloses a retractor for neurosurgery. The retractor comprises four connecting pipes, four connecting cylinders and an adjusting mechanism; the two ends of each connecting pipe are arranged in the different connecting cylinders in a sliding and sleeved mode respectively, and the adjacent connecting pipes are sequentially connected through the connecting cylinders to form a closed rectangular frame; the adjusting mechanism comprises a first rotating shaft, a first rack and a first gear; the first rotating shaft is fixedly sleeved with the first gear; the first rack is arranged ina first guide groove; the ends of the two ends of the first rack extend into the connecting cylinders; the first rack is in engaged connection with the first gear; and one end of the first rotating shaft is inserted into the connecting pipes, and the other end is arranged outside the connecting pipes. According to the retractor for the neurosurgery, the first rotating shaft is rotated to drive the first rack and a second rack to move in the first guide groove and a second guide groove correspondingly, so that the ends of the connecting pipes slide in the connecting cylinders, the distance between every two adjacent connecting pipes is freely adjusted according to the size of a wound, and the retractor adapts to and fixes 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...
