Abstract

1534472 Surgical coding and cauterisation devices ERBE ELEKTROMEDIZIN KG 2 May 1977 [14 May 1976] 18322/77 Heading A5R A cryosurgical probe comprises a heating coil 5 for thawing the probe and cauterisation purposes, fitted into a hollow inner cooling section of the cooling tip, the heating coil being such that cauterisation may follow a freezing procedure, and a film 7 of flexible elastomeric plastics material provided on the outer surface of the probe, at least over the part of the probe causing cauterisation, the plastics material being such as to withstand temperatures of up to 200‹C and to prevent tissue adhering during the cauterisation process. The probe also includes a refrigerant, e.g. liquid nitrogen, supply line 1 inside a heat-insulating shaft 6 and has a temperature sensor 9. The heating coil may have a power rating of 120 Watts to reach cauterisation temperatures. A heat insulating tip 10 is provided to prevent unintended freezing or cauterisation of the bladder wall in a transurethral resection operation. The film 7 may be a linear copolymer of vinylidene fluoride and hexafluoropropylene, and the tip may be of the same material or polytetrafluoroethylene.
