Horizontal Microsurgery Scissors

Horizontal Microsurgical Scissors

This technology is a microsurgical instrument that utilizes the deformation of a tension pressure unit within a surgical robot arm to convert vertical physical movement into horizontal motion via a bent link structure, thereby driving the scissor mechanism to open and close the blades.

Existing surgical tools are limited to vertical movement because the scissor blades are aligned with the robot arm, which reduces accessibility and operational efficiency when dissecting or incising vertically elongated scar tissue.

This technology features a bent internal core that positions the scissor blades along a horizontal axis. It employs a mechanism that converts vertical transfer force into horizontal driving force by transmitting pressure changes from the tension pressure unit through a vertical transfer tube, a transfer connection tube, and a horizontal transfer tube. Applicable to surgical robots, interventional systems, and medical automation, it enables users to perform procedures with greater control and accuracy, thereby enhancing the precision and effectiveness of microsurgery.

Key Features:

• A horizontal microsurgical scissor for incising patient lesions, comprising a scissor robot arm that includes a scissor unit for cutting micro-tissues,
• a tension pressure unit provided on the outer circumference of an internal core that changes in length due to pressure,
• a scissor opening/closing unit that opens and closes the scissor unit according to the movement of an external barrel,
• and an external barrel with one end formed in close contact with the lower end of the tension pressure unit, moving in the opposite direction of the one end according to the length change of the tension pressure unit.
