Operation retractor provided with multi-claw adjusting function

Abstract

The invention relates to a medical auxiliary tool, in particular to an operation retractor provided with a multi-claw adjusting function. The operation retractor is fixed on an operation table through a suspending frame, a rotating hand wheel is rotated by a hand to drive a worm to rotate, the worm rotates, moves downward and is in meshing transmission with a worm wheel, the worm wheel and a rocking arm are driven to drive retractor claws to move together, a ratchet wheel arranged at the upper end of each retractor claw and a ratchet claw arranged at the lower part of the rocking arm are meshed, the ratchet claw provides a restoring force through a reset spring and is still located in a tooth groove of the ratchet wheel, and the ratchet claw is clamped inside the tooth groove of the ratchet wheel and is locked. More than four retractor claws evenly distributed inside a hinged supporting base frame can realize the synchronous unfolding or synchronous contracting, the operation is simple, and the operation view can be effectively exposed. Meanwhile, the supporting inclined angle of any retractor claw can be manually and independently adjusted according to needs, all tissues can be conveniently and effectively retracted during an operation, and the adjusting is flexible.

Description

technical field [0001] The invention relates to a medical auxiliary tool, in particular to an operation retractor with multi-claw adjustment function. Background technique [0002] Retractors, also known as retractors, are used to retract tissues and expose the surgical field for easy exploration and operation. They can be divided into two types: hand-held retractors and automatic retractors. There are various specifications of different shapes and sizes, and the appropriate retractor can be selected according to the operation needs. Automatic retractors are self-fixing retractors, also known as self-sustaining retractors, such as two-leaf and three-leaf automatic retractors, which can be used in operations on the abdominal cavity, chest cavity, pelvic cavity, waist, and brain. Omni-directional surgical retractor is a new type of automatic retractor, which can fully expose the surgical field, save 1-2 assistants, and significantly reduce the labor intensity of surgical assi...

AI Technical Summary

Problems solved by technology

However, the existing retractors have complex structures, occupy a large space, are inconvenient to operate, are troublesome to use, are not convenient for exploration and operation, and cannot effectively reveal the surgical field.
