Cryosurgical device with a probe coupling formed from the socket and the plug of cryoprobes

摘要

A cryosurgical device, with a control for the supply and/or removal of a coolant gas to a cryoprobe via a return flow or a supply flow. The device has at least one socket for the attachment of a rigid cryoprobe and a flexible cryoprobe. The socket and the plugs of the cryoprobes each form probe couplings. The configuration of the cryosurgical device allows both rigid and flexible cryoprobes to be automatically connected to the appropriate return flow conduit, independently of the level of knowledge of operating personnel.

1. A cryosurgical device comprising:
a first type of cryoprobe comprising a first-cryoprobe supply flow conduit and a first-cryoprobe return flow conduit; a second type of cryoprobe comprising a second-cryoprobe supply flow conduit and a second-cryoprobe return flow conduit; a socket comprising a socket supply flow conduit and two socket return flow conduits, wherein the first type of cryoprobe and the second type of cryoprobe are configured to be inserted into the socket such that only one of the first type of cryoprobe and the second type of cryoprobe is inside the socket at a time a control for a supply and a removal of a coolant gas to the first type of cryoprobe and the second type of cryoprobe when inserted into the socket; wherein the second-cryoprobe return flow conduit requires a different supply pressure or backflow pressure than the first-cryoprobe return flow conduit, and wherein the removal of the coolant gas from the second type of cryoprobe when inserted in the socket takes place via the second-cryoprobe return flow conduit and a first of the two socket return flow conduits and the removal of the coolant gas from the first type of cryoprobe when inserted in the socket takes place via the first-cryoprobe return flow conduit and a second of the two socket return flow conduits.
