Medical vacuum tweezers and a tissue suturing device incorporating them

Medical vacuum tweezers for tissue suturing

This technology describes a medical vacuum tweezers that forms needle holes and depressions on opposing plates and constitutes a tube, and a tissue suturing device including it.

In microsurgeries, such as ophthalmology, it has been difficult to precisely control the shape and depth of sutures.

This technology improves the accuracy and controllability of wound suture shape and depth by inducing temporary deformation of the contacted tissue through the depressions within the vacuum tweezers.

Key Features:

• Needle holes formed on opposing first and second plates
• Side plates connecting the plates to form a tube
• Depressions positioned higher than the suture needle
• Improved accuracy and controllability of suture shape and depth
