Mandibular sinus membrane separator capable of detecting tissue perforation

摘要

A pump (19) is connected to a fluid source (26) and conveys a controlled volume of fluid. A fluid line (15) is connected between the fluid source and an access port (12) to the tissue layers (2,9), to supply fluid to between the layers. A sensor (21) detects values characterizing the pressure in the flow path of the fluid. A control device receives signals generated by the sensor and evaluates them to regulate the volume of fluid to be fed, and to detect unacceptable changes in pressure.
