Abstract
A bioelectronic surgical suture for monitoring suture tension includes a conductive material made of electropositive material, and a sleeve made of electronegative material. The sleeve is a hollow capillary, the conductive material is arranged in the sleeve through infusion, and is processed by a first laser scanning operation after infusion. An outer wall of the sleeve has a micro-nano structure manufactured by a second laser scanning operation.
Claims7
A bioelectronic surgical suture for monitoring suture tension, comprising:
- a conductive material made of electropositive material, and
- a sleeve made of electronegative material, wherein
- the sleeve is a hollow capillary, the conductive material is arranged in the sleeve through infusion, and is processed by a first laser scanning operation after infusion;
- an outer wall of the sleeve has a micro-nano structure manufactured by a second laser scanning operation;
- the bioelectronic surgical suture is a self-powered sensor based on a principle of triboelectric nanogenerator;
- and the suture tension of the bioelectronic surgical suture causes changes in a contact area between the bioelectronic surgical suture and a sutured tissue, and output electrical signals changes to monitor the suture tension on the bioelectronic surgical suture.
