DEVICE FOR instillation of liquid nitrogen at bone resection for tumors and tumor-like lesions

摘要

The utility model is intended for use in medicine, namely to traumatology and orthopedics, pediatric surgery and oncology, serves directly for surgery for tumors and tumor-like bone lesions. The proposed utility model aims to improve ease of use and the ability to conduct high-quality cryosurgical tool in the surgical treatment of tumors and tumor-like lesions of bone resection with various defects that can increase the effectiveness of treatment. Said technical result is achieved in that the cylinder cover is provided with a check valve for relieving excess pressure nitrogen gas cylinder connected to the adapter tube bent at an angle of 40-45 degrees, and Parker, which is placed in the upper hole tee which connects the proximal and distal part of the device, wherein is a needle moving inside the tee guide and the seals by the trigger with a return spring and a plug, and a front opening through a pad connecting tee Xia with the pipe, located in the coupling-tube having an open end, ground off at an angle of 45 degrees with the nipple used as a hose nozzle for electric pumps for discharging steam during instillation of liquid nitrogen into the bone wound. The device is made of a single-layer chemically resistant stainless steel insulated with the exception of the body casing and the handle linings made of fluoroplastic.
