摘要
The liquid nitrogen cryosurgical apparatus with a set of Suwalski cardiac surgery cryoprobes comprises of the liquid nitrogen container (1) installed on the mobile frame (11) comprising of a base and a profiled extension arm. The container (1) cooperates with the supply head (5) which is detachably connected to the supply line (2) by means of connector (7) fastening the line (2) to the head (5). The cooling medium used is the liquid nitrogen which is transported from the container (1) through the supply line (2) and is supplied to the selected Suwalski cardiac surgery cryoprobe (4) tip seated in the socket inside the handle (3) of the supply line (2). The supply line (2) comprises of four coaxially arranged flexible hoses, and the first internal hose (14) supplies the liquid nitrogen. The electrical system of the supply head (5) is connected by means of the power supply connector (8), located on the wiring harness end, with the control panel (6) installed on the mobile frame (11) extension arm. The line (2) handle (3) holder (12) is also attached to the extension arm of the said frame (11). On the base of the mobile frame (11) the power switch (9) with a network cable socket, fuses (10) and the supply head (5) holder (13) are located. On the end of the supply line (2) a teflon locking sleeve (15) is located. One end of the sleeve (15) has a cryoprobe teflon socket (16, 17) attached, whereas on the other end a teflon mounting socket (19) of the first internal hose (14) is located.
