Abstract

The invention discloses a hydrophilic interface manufacturing method and system for holding biological tissues. The method comprises the steps: obtaining the maximum slippage force and the minimum damage force of a biological tissue in advance, and selecting a force value which is greater than the maximum slippage force and is smaller than the minimum damage force as the tension of an optimized liquid film; determining an optimized structure parameter value corresponding to the optimized liquid film tension according to the relationship between the structure parameter of the hydrophilic interface and the liquid film tension, and manufacturing the hydrophilic interface according to the optimized structure parameter value, thereby realizing accurate design of the structure parameter of the hydrophilic interface. The liquid film tension of the manufactured hydrophilic interface is accurately controlled between the maximum slippage force and the minimum damage force, so that the liquid film tension generated by the hydrophilic interface realizes stable and non-damage clamping and pulling of the interface and human tissues, and the technical problems of tissue damage and slippage easilycaused when an existing surgical instrument clamps biological tissues are solved.

Description

technical field

[0001] The invention relates to the field of manufacturing a hydrophilic interface of surgical instruments, in particular to a method and system for manufacturing a hydrophilic interface for absorbing biological tissues. Background technique

[0002] Different from open surgery and traditional endoscopic surgery, the surgical robot completes the surgical operation through the mapping action of the mechanical device. The surgeon cannot directly touch the tissue, and cannot provide real-time feedback on the force load on the hydrophilic interface of the tissue during the operation through the limb receptors. Only through visual feedback and The operating experience of the surgeon judges the stress on the tissue. There is a lack of force feedback, and the force load output cannot be adjusted in a timely and accurate manner, which may easily lead to irreversible damage such as tissue tearing and bleeding. Therefore, how to eliminate the abnormal mechanical contac...
