Retractor for surgical operation

Abstract

The invention relates to a retractor for a surgical operation.The retractor comprises a hinge base.Movable arms are arranged on the two sides of the hinge base and hinged to the hinge base.Each movable arm comprises a retraction rod, wherein the retraction rod is provided with grabbers.The movable arms are connected with a control device for controlling the movable arms to be opened and closed.The control device comprises push rods and a control rod.The push rods are fixedly connected with the movable arms.The control rod penetrates through the hinge base and comprises a connecting plate.The connecting plate is provided with a pair of jack props.Each push rod is provided with a long hole.The jack props are matched with the long holes in the push rods.The hinge base is provided with a fastening bolt.Torsion springs are arranged between the movable arms and the hinge base.The hinged points of the movable arms and the hinge base are located on the axes of the push rods.The push rods are pushed away through the control rod, so that the movable arms are driven to be opened to retract tissue, the control rod is fixed to the hinge base through the fastening bolt, positioning is firm and reliable, and operation is easy and convenient.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a surgical retractor. Background technique [0002] A retractor is a surgical instrument used to retract the muscle tissue at the surgical incision, revealing the surgical field of view, and facilitating exploration and operation. Commonly used retractors include metal retractors and soft retractors. At present, the mechanical double-claw retractors commonly used in surgery are mostly made of metal materials such as stainless steel and titanium alloys. The advantages are that they can provide a large supporting force for the surgical incision and allow repeated disinfection. After the retractor retracts the surgical incision, it needs to be kept open to facilitate the operation. At present, when the common retractor retracts the musculature to both sides, it needs to be strenuously retracted, which is inconvenient to operate. And when the retractor is positioned in a state, ...

AI Technical Summary

Problems solved by technology

At present, when the common retractor retracts the muscle tissue to both sides, it needs to be pulled apart with great effort, which is inconvenient to operate

And when the retractor is positioned in a state, the positioning device is relatively cumbersome to operate, and the retractor is likely to be automatically closed when the muscle tissue at the incision contracts, which brings inconvenience to the operation, and even affects the operation process, causing accidents.
