Abstract

1339218 Cryosurgical instruments R M WALLACH 29 Sept 1972 [6 Oct 1971] 45177/ 72 Heading A5R A cryosurgical instrument comprises a probe 14 having an internal expansion chamber 30 to which refrigerant is supplied through a restricted orifice 66 for providing a Joule-Thomson expansion of the refrigerant in the chamber, effluent gas being conveyed from the chamber along a path including a flow control valve 42 for selectively opening and closing the path. Saturated gas, e.g. carbon dioxide or nitrous oxide, is fed from cylinder 22 to expansion chamber 30 through a conduit 51 coaxial with a tubular body 13, the space therebetween providing a return path 67 for effluent gas. The path 67 communicates with valve 42 which has a flow passage 94, 92, 96 therethrough which is controlled by a valve element 100 biassed by spring 102 so that a segment 113 of the valve element seats against the inlet to bore 96. A lever 12 is pivotally connected to the valve element so that when lever 12 is moved anticlockwise valve element 100 moves against the spring to open the bore 96 and hence the passage through the valve to atmosphere at 44. A sintered disc 90 reduces the noise of escaping gas. To enable the flow passage to be kept open, the upper edge of lever 12 is bevelled and its connection to the valve element is such that it can be rotated clockwise to abut housing 106 thereby biassing the valve to the open position. The spring 102 is such that if the pressure within the instrument exceeds a predetermined amount the pressure acting through bore 94 on a shoulder 120 of the valve element will move the valve element away from the bore 96. A valve 20 is provided to interrupt the supply of refrigerant. In a valve modification, the segment 113 of the valve element is tapered and means are provided for presetting the distance by which it can move away from bore 96 thereby varying the size of the inlet to bore 96 to obtain a predetermined refrigerant flow rate and hence predetermined temperature of the probe.
