SURGICAL SCALPEL FOR ELECTROSURGERY AND ELECTROSURGICAL SYSTEM

摘要

A surgical scalpel for electrosurgery and an electrosurgical system.The surgical scalpel includes a scalpel handle (40) and a scalpel head (41) mounted on the scalpel handle (40) detachably. The scalpel head (41) includes an external conductor (413), an internal conductor (411), an insulating medium (410), a positive electrode (412) and a water supply pipe (419).An arch shaped notch (4132) is provided at the external end of the external conductor (413). An upper external electrode (4133) and a lower external electrode (4131) are provided at the two ends of the arch shaped notch (4132), respectively. The insulating medium (410) and the internal conductor (411) are fixedly mounted inside the external conductor (413). The insulating medium (410) is located between the external conductor (413) and the internal conductor (411).The positive electrode (412) is provided on the external conductor (413) or the internal conductor (411). The water supply pipe (419) is provided in the external conductor (413) or in the insulating medium (410).The invention makes use of the advantages of a radio frequency electrosurgical scalpel, a medical water jet scalpel, and a microwave surgical scalpel.
