摘要:
The invention relates to medical engineering and can be used for carrying out local cooling of various biological tissues for medical purposes, including for cryoablation limited volume pathological human tissue for the treatment of superficial and endocavitary cancer tumors, in urology, gynecology, neurosurgery, ophthalmology, dermatology, otolaryngology. The proposed autonomous device for locally cooling a biological tissue, comprising a thermally insulated cylindrical sealed housing containing a sealed metal flask and heat insulating sheath of polyurethane foam, a gate supply line cryoagent and working tip, sealed steel flask provided with a convex bottom insulating sheath of polyurethane foam has a recess in the central bottom body portion, the thickness of foam between the recess and the center of the bottom of the sealed metal oh flask 0.2-0.5 polyurethane insulation thickness in the cylindrical portion of the housing. The recess in the central part of the bottom of the housing has the form of a truncated cone having a large base diameter of 60-70 mm and a flat or convex small base. The thickness of the foam between the recess and the center of the bottom of the flask sealed metal is in the range 2-5 mm. The apparatus is provided with a support in the form of a flat disk with the protrusion of the polyurethane foam within the recess of the insulating sheath of polyurethane foam in the central part of the bottom of the housing. The stand can be fastened to a flat disk of material of high density, for example, a metal device has improved performance and ergonomics due to the optimal distribution of heat leakage along the surface of a device which performs reduction of heat leakage in the standby mode on the auxiliary table for Instrumentation (when preparing cryoprocedure) and increase during the procedure.Полезная модель относится к медицинской технике и может быть использовано для осуществления локального охлаждения различных биологических тканей с медицинской
