A novel hand-held surgical retractor, designed like a bayonet, simultaneously retracts both sides of an incision. This versatile instrument offers potential applications beyond its primary surgical use.

Area of Science:

Surgical instrumentation
Medical device design

Background:

Surgical procedures often require effective tissue retraction to ensure adequate visualization and access.
Existing retractors may necessitate multiple instruments or additional personnel for simultaneous bilateral retraction.

Purpose of the Study:

To introduce a novel hand-held surgical retractor.
To describe the design and functionality of a cross-action bayonet-style retractor.
To highlight the device's capability for simultaneous retraction of bilateral incision lips.

Main Methods:

Design and fabrication of a hand-held surgical retractor.
The retractor features a double-bladed, cross-action bayonet configuration.
Evaluation of the device's ability to retract both sides of an incision concurrently.

Main Results:

A functional hand-held double-bladed retractor was successfully designed.
The cross-action bayonet mechanism allows for simultaneous retraction of opposing incision edges.
The device demonstrated efficacy in retracting both lips of a surgical incision.

Conclusions:

The designed retractor offers a streamlined approach to simultaneous bilateral wound retraction.
The innovative design may improve surgical efficiency and reduce the need for additional surgical assistants.
The retractor's adaptable design suggests potential for broader clinical applications.
