AI Technical Summary

Technical Problem

Traditional surgical incision expansion methods require assistance from multiple assistants, which increases the risk of intraoperative contamination. Handheld surgical hooks cause fatigue and instability in the operation of medical staff. The existing forceps cannot fully open the incision, occupying surgical space, affecting the main surgery Doctor's operation.

Method used

A surgical incision dilator including an articulated expansion member and a removable expansion mechanism is designed to deform the expansion member in a transverse position by rotating the electric drive rod, increasing the incision expansion range, and ensuring by magnetic adsorption and limiting tabs. Stability and easy disassembly of the expander.

Benefits of technology

A wider surgical incision opening is achieved, reducing fatigue of medical staff, providing maximum surgical space, and ensuring stability and convenience of the dilator during use and disassembly.

Abstract

The invention discloses a surgical incision dilator. The surgical incision dilator comprises a dilating part, a positioning strip and a dilating mechanism, the two groups of expansion pieces are horizontally arranged, the two ends of the two groups of expansion pieces are hinged to the same hinge piece respectively, and the two groups of expansion pieces can deform outwards in the middle positions of the expansion pieces under the action of external force; the positioning strip is arranged between the two hinging pieces, the two ends of the positioning strip are detachably connected relative to the hinging pieces, and the length of the expansion piece can be kept unchanged in the longitudinal position of the surgical incision in the deformation process of the expansion piece; the expansion mechanism is arranged on the positioning strip and used for applying external force capable of enabling the expansion piece to deform to the expansion piece, so that the expansion piece expands the surgical incision in the transverse position of the surgical incision; according to the surgical incision expander provided by the invention, the area of a part in contact with a surgical incision is increased, so that the expanded range of the surgical incision is expanded; after the surgical incision is expanded and fixed, the expansion mechanism can be detached to provide the maximum surgical space.
