Abstract
The invention concerns a surgical apparatus for irrigating an operative site during endoscopic surgery. The apparatus comprises a reservoir of irrigation fluid contained within an air actuated pouch, a pump for inflating the pouch so that the reservoir is compressed, pressure control means, a microprocessor for operating the system, heating panels contained within the pouch for providing heated irrigation fluid, and a nozzle and tube for delivering the irrigation fluid to an operative site. The apparatus also provides a stick fitting for attaching tubing to the fluid reservoir. In addition to the stick fitting, the apparatus provides a locking receiver system for insuring that the stick fitting will not disengage during use.
Claims21
A surgical apparatus, comprising:
- a flexible pouch having a substantially enclosed inside cavity defined by at least one flexible wall for containing and substantially fully enclosing at least bottom and side surfaces of a disposable flexible fluid reservoir;
- said pouch further comprising a second inflatable cavity exterior to said inside cavity for receiving a pressurized fluid and applying a compressive force against said at least one flexible wall of said inside cavity.
A surgical apparatus for preventing contamination of irrigation fluid during surgery, comprising:
- a flexible pouch having a substantially enclosed inside cavity defined by at least one flexible wall for containing and substantially fully enclosing at least bottom and side surfaces of a disposable flexible fluid reservoir, and a second inflatable cavity external to said inside cavity for receiving a pressurized fluid and applying a compressive force against said at least one flexible wall of said inside cavity;
- a pump for inflating said second cavity;
- pressure control means for regulating said pressurized fluid;
- and
- a heater for heating said fluid.
A surgical apparatus for reducing the risk patient hypothermia and contamination of irrigation fluid during surgery, comprising:
- a flexible pouch having a substantially enclosed inside cavity defined by at least one flexible wall for containing and substantially fully enclosing at least the bottom and side surfaces of a disposable flexible fluid reservoir, said reservoir having a stick fitting secured to said bottom through which said fluid is discharged, a second inflatable cavity external to said inside cavity for receiving a pressurized fluid and applying a compressive force against said at least one flexible wall of said inside cavity, said second cavity having a plurality of chambers, said chambers being interconnected by channels for even inflation of said second cavity, a heater having at least one heating panel within said pouch inside cavity for heating said fluid;
- a support bag for containing said reservoir, said support bag being insertable into said pouch;
- a pump for inflating said second cavity;
- a solenoid valve for regulating said pressurized fluid;
- said at least one heating panel further comprising thermistors for maintaining said fluid at a temperature between about 85.degree. F. and about 115.degree. F.
