Vessel sealing forceps with a bipolar electrode

摘要

PROBLEM TO BE SOLVED: To provide bipolar forceps which can seal a blood vessel and tissue consistently and effectively, and cannot be damaged by continuous use and cleaning.;SOLUTION: The bipolar electric surgical instrument (hereafter referred to as forceps) includes end effectors 22, 24, facing each other, and a handle 16 to relatively move end effectors to each other. An electrode assembly 21 can be attached to and removed from forceps. The electrode assembly comprises a pair of electrodes attached to the distal end facing each other. Each of the electrodes can removably engage with one of the end effectors. As a result, the electrodes is present in such a relation as to face each other. At least one stopper member controls the distance between the electrode assembly and the facing electrode. The bipolar forceps include at least one stopper member which can selectively engage with at least one of the electrodes.;COPYRIGHT: (C)2009,JPO&INPIT
