ABSTRACT:
An endoscope for use in the removal of tumors from hollow body organs such as the bladder. The endoscope consists of a sheath (49) through which extends a telescope (40) and a suction diathermy tube (2, 31, 60) the non-operation end (3, 33) of which communicates with a suction device. Provision (51, 52) is made for an irrigation fluid to be passed through the endoscope. The diathermy tube (2, 31, 60) has an electrode tip (7, 8) which may be formed from electrically conducting resistance wire connected (5, 39, 63) to a diathermy machine. The electrode tip is found adjacent an aperture (4, 9, 41) at the operative of the tube whereby tissue can be immediately removed by suction after severance by the electrode tip. The degree of suction applied to the tube (2, 31, 61) is controlled by a finger hole (38a, 55, 66) located at or near the end (3, 33) of the tube (2, 31, 61). Alternatively the tube (31) may be formed of a metal tube (34) coated with an insulating plastics material (35) and having a cutting or coagulating tip (34a), provision (37, 38, 43, 45, 53, 54) being made for reciprocating the tube up and down the endoscope.
