Retraction device for clinical operation of neurosurgery department

Abstract

The invention relates to the field of medical treatment, in particular to a neurosurgery clinical operation retractor which comprises two telescopic rods, the two telescopic rods are perpendicular to each other, a supporting ring is mounted at the moving end of the transverse telescopic rod, and positioning holes are formed in the upper surface of the supporting ring in the circumferential direction. The outer wall of the supporting ring is sleeved with a plurality of retraction mechanisms in the circumferential direction, and amplification mechanisms are installed at the top ends of the retraction mechanisms; the retraction mechanism comprises a supporting seat, the supporting seat sleeves the outer wall of the supporting ring, the supporting seat is U-shaped, a positioning pin is mounted at the top end of an inner cavity of the supporting seat, the positioning pin is inserted into an inner cavity of the positioning hole to prevent the supporting seat from being positioned, and a supporting plate is mounted at the top end of the supporting seat. Multi-point and multi-angle retraction of tissue can be achieved, the retraction area meets the retraction requirement, an operation is facilitated, the operation view is enlarged, the operation difficulty is reduced, and asthenopia of a doctor is prevented.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a retractor device for clinical neurosurgery. Background technique [0002] Neurosurgery is a branch of surgery that applies unique neurosurgery research methods on the basis of surgery as the main treatment method to study the human nervous system, such as the brain, spinal cord and peripheral nervous system, and related affiliates. Retractors are often used in neurosurgery. Retractors, also known as retractors, are used to retract tissues, reveal the scope of surgery, and facilitate exploration and operation. They can be divided into two types: hand-held retractors and automatic retractors. There are various shapes and sizes of specifications, and the appropriate retractor can be selected according to the needs of the operation; [0003] The retractor is an essential instrument for medium and large-scale operations. The number of retractors and the retraction angle of the re...
