1. An endosurgical device comprising:
a tube having a proximal tube end and an opposite distal tube end, and at least one lengthwise extending channel extending there-between,
an end effector provided at the opposite distal tube end, and
a device operating part at the proximal tube end, wherein
the tube has a first lengthwise extending channel of the at least one lengthwise extending channel for supplying a liquid to the end effector, a second lengthwise extending channel of the at least one lengthwise extending channel for removing matter from or at the end effector, and a third lengthwise extending channel of the at least one lengthwise extending channel for accommodating an electrical wire connected to the end effector to apply current to perform diathermy,
an effector sleeve surrounds the tube at least at the opposite distal tube end of said tube, and being arranged to enclose at least at the opposite distal tube end of the tube,
the device operating part comprises a slide rail assembly, the slide rail assembly comprises at least a main slide guide body that accommodates an end effector slider and a junction slider,
the main slide guide body has a guideway with a proximal guide end and an opposite distal guide end that receives the tube,
the end effector slider is adapted to slide in the guideway at the opposite distal guide end, and is connected to the effector sleeve to operate said effector sleeve in relation to the end effector, and
the junction slider is adapted to slide in the guideway between the proximal guide end and the end effector slider, the junction slider is connected to the tube to arrange the first lengthwise extending channel of the at least one lengthwise extending channel, the second lengthwise extending channel of the at least one lengthwise extending channel and the third lengthwise extending channel of the at least one lengthwise extending channel of the tube in communication with the end effector.
