Publication number: 20240060584Abstract: A connection portion for a surgical instrument provides an improved means of connection between a surgical instrument and a hose. The hose may supply irrigation fluid or may be connected to a suction source. The connection portion includes a part which is connected to and movable with the hose, ensuring that the connection between the connection portion and the hose does not limit the flow of fluid through the hose even as the hose moves. This further reduces the apparent feeling of weight caused by the hose on the surgical instrument.Type: ApplicationFiled: August 14, 2023Publication date: February 22, 2024Applicant: GYRUS MEDICAL LIMITEDInventor: Christopher CHAPMAN
