Abstract
An irrigation/aspiration apparatus is provided for use with surgical instrumentation requiring irrigation and aspiration of fluids and a peristaltic pump. The apparatus includes a housing and a manifold for connecting a transfer tube with aspiration and irrigation lines from the surgical instrumentation and with waste and supply lines. An opening the housing enables access to the transfer tube in order to control fluid flow therein. A diaphragm mounted to the housing and in fluid communication with the aspiration tube enables both pressure measurement and pressure control in the tubing when the housing is inserted into a drawer in the console and in operative engagement with a peristaltic pump head disposed therein.
Claims16
An irrigation/aspiration apparatus for use with surgical instrumentation requiring irrigation and aspiration of fluids and a peristaltic pump, the apparatus comprising:
- an aspiration tube;
- a housing comprising means for both supporting the aspiration tube and enabling access thereto for contact with a peristaltic pump head and for connecting said aspiration tube with an aspiration line of a surgical device;
- means for connecting a supply line to both the aspiration line and an irrigation line of the surgical device;
- means for enabling the regulation of irrigation fluid flow in said supply line into both said irrigation and aspiration lines of the surgical device;
- and
- means, comprising a diaphragm, for both measuring fluid pressure in the aspiration line and for abruptly changing the pressure of the fluid in the aspiration line by movement of the diaphragm in response to the pressure measurement.
An irrigation/aspiration apparatus for use with surgical instrumentation requiring irrigation and aspiration of fluids and a peristaltic pump, the apparatus comprising:
- a housing;
- manifold means, removably attached to said housing, for connecting a transfer tube with aspiration and irrigation lines from the surgical instrumentation and with waste and supply lines;
- means, defining an opening in said housing, for enabling access to a transfer tube connected to the aspiration line for engagement with a peristaltic pump head;
- means for enabling control of fluid from said supply line to both said aspiration and irrigation lines through said transfer tubes;
- and
- first diaphragm means for measuring fluid pressure in the aspiration line through the transfer tube, and
- second diaphragm means responsive to the pressure measurement for abruptly changing the pressure of the fluid in the aspiration line by movement of the diaphragm.
Irrigation/aspiration apparatus for use with surgical instruments requiring irrigation and aspiration of fluids and an instrument console having a peristaltic pump head and an opening for access thereto, the apparatus comprising:
- a housing adapted for insertion into the instrument console opening and comprising means for both supporting an aspiration tube and for enabling operational contact therewith by said peristaltic pump head when the housing is inserted into the instrument console opening;
- a diaphragm attached to said housing and in fluid communication with said aspiration tube;
- a pressure transducer disposed in said instrument console;
- a solenoid disposed in said instrument console;
- and
- means, attached to said diaphragm, for removably coupling said diaphragm to both the pressure transducer and the solenoid, when said housing is inserted into the instrument console opening.
