Abstract
A miniaturized pump assembly for inflow and outflow of fluid gas and smoke during arthroscopic and laparoscopic surgery.
Claims12
An arthroscopic surgical pump system comprising:
- a housing characterized by a distal end, a proximal end, and an inner diameter sized and dimensioned to be removably disposed over an arthroscopic instrument;
- and
- a modular pump assembly having a distal end and a proximal end, comprising:
- a inflow pump having at least one fluid inlet port for introduction of fluid from a fluid source;
- an outflow pump connected in series to the inflow pump and having at least one fluid output port for transmission of fluids out of the outflow pump;
- a pressure sensor contained at an end of the pump assembly and operable to obtain pressure readings and transmit the readings;
- and
- a pump controller operable to receive the readings from the pressure sensor to adjust the fluid introduction to the inflow pump or the expulsion of fluid from the outflow pump to maintain the pressures within a predetermined range;
- and
- wherein the modular pump assembly is entirely contained within the housing.

An arthroscopic surgical pump system comprising:
- a housing characterized by a distal end, a proximal end, and an inner diameter sized and dimensioned to be removably disposed over an arthroscopic instrument and including an outflow sheath within the housing;
- and
- a modular pump assembly having a distal end and a proximal end, comprising:
- a first inflow pump having at least one fluid inlet port for introduction of fluid from a fluid source;
- a second inflow pump connected in series to the first inflow pump;
- a pressure sensor contained at an end of the pump assembly and operable to obtain pressure readings and transmit the readings;
- a outflow pump connected in series to the first and second inflow pumps and having at least one fluid output port for transmission of fluids out of the outflow pump;
- and
- a pump controller board operable to receive the readings from the pressure sensor to adjust the fluid introduction to either the first or second inflow pump to maintain the pressures within a predetermined range;
- and
- wherein the modular pump assembly is entirely contained within the housing.
