Title
(EN) ELECTROSURGICAL INSTRUMENT
(FR) INSTRUMENT ÉLECTRO-CHIRURGICAL
Abstract
(EN)
An electrosurgical device having a radiating tip portion for delivering electromagnetic energy to biological tissue, where the electrosurgical device is disposed in a catheter. The electrosurgical device is movable relative to the catheter between a deployed position where the radiating tip portion is exposed and a retracted position where the radiating tip portion is contained within the catheter. In this manner, the radiating tip portion may be retracted until the moment when it is to be used. This may facilitate insertion of the device through an instrument channel of a surgical scoping device. In particular, this may prevent the radiating tip portion from catching on the instrument channel when the device is inserted into the instrument channel, which could cause damage to the instrument channel and/or radiating tip portion.
(FR)
Dispositif électro-chirurgical comportant une partie pointe rayonnante pour délivrer de l'énergie électromagnétique à du tissu biologique, le dispositif électro-chirurgical étant disposé dans un cathéter. Le dispositif électro-chirurgical est mobile par rapport au cathéter entre une position déployée dans laquelle la partie pointe rayonnante est exposée et une position rétractée dans laquelle la partie pointe rayonnante est contenue à l'intérieur du cathéter. De cette manière, la partie pointe rayonnante peut être rétractée jusqu'à ce qu'au moment où elle doit être utilisée. Ceci peut faciliter l'introduction du dispositif dans un canal d'instrument d'un dispositif d'endoscopie chirurgicale. En particulier, ceci peut empêcher la partie de pointe rayonnante de s'accrocher sur le canal d'instrument lorsque le dispositif est introduit dans le canal d'instrument, ce qui pourrait provoquer un endommagement du canal d'instrument et/ou de la partie pointe rayonnante.
