Area of Science:

Biomedical Engineering
Surgical Instrumentation
Microsurgery Techniques

Context:

Traditional retractors in microsurgery can limit operative field visibility and cause collateral tissue trauma.
Mouse models are crucial for preclinical research, requiring precise surgical tools.

Purpose:

To develop and evaluate a novel retractor system utilizing a magnetic fixator for enhanced mouse microsurgery.
To compare the efficacy of the new retractor against traditional methods in otocyst exposure procedures.

Summary:

A novel retractor with a magnetic fixator was designed using a magnet, screw, nuts, and stainless steel wire hook.
The retractor allows for rapid tissue retraction, creating an expanded and clear operative field.
Adjustable height, orientation, and traction strength offer precise control during microsurgery.

Impact:

The novel retractor facilitates a shorter operative incision, reducing trauma to muscles and vessels.
It minimizes the accidental rate of bleeding during mouse microsurgery.
This tool provides a simple, powerful, and minimally invasive solution for mouse microsurgery, particularly for otocyst exposure.
