Title: Innovations of Keith E. Nelson
Introduction
Keith E. Nelson is a notable inventor based in Los Angeles, California. He has made significant contributions to the field of cryosurgery, holding two patents that showcase his innovative approach to medical technology. His work focuses on developing disposable cryosurgical probes that enhance surgical efficiency and patient safety.
Latest Patents
One of his latest patents is the "Disposable, defrostable cryosurgical probe." This small, disposable device features a self-contained liquid refrigerant supply, allowing it to operate in both freeze and defrost modes. In freeze mode, the refrigerant is delivered to the probe tip as a two-phase fluid, enabling prolonged freezing of tissue with a limited refrigerant supply. To detach the probe tip from tissue, a button is pressed to switch to defrost mode, where room temperature liquid refrigerant is used to warm the tip. This innovative design allows for multiple cycles between freeze and defrost modes before the refrigerant supply is depleted.
Another significant patent is the "Cryosurgical probe," which is also a small, self-contained, disposable device. It features a pencil-like housing that contains a refrigerant cartridge and a hollow tip. A capillary tube connects the cartridge to the tip, with a multi-turn coil design that stabilizes the refrigerant temperature. This ensures a uniform mass flow rate of refrigerant to the probe tip, enhancing its effectiveness during surgical procedures.
