چکیده انگلیسی
Waterjet cutting technology is considered a promising technology to be used for minimally invasive removal of interface tissue surrounding aseptically loose hip prostheses. The goal of this study was to investigate the feasibility of waterjet cutting of interface tissue membrane. Waterjets with 0.2Â mm and 0.6Â mm diameter, a stand-off distance of 5Â mm, and a traverse speed of 0.5Â mm/s were used to cut interface tissue samples in half. The water flow through the nozzle was controlled by means of a valve. By changing the flow, the resulting waterjet pressure was regulated. Tissue sample thickness and the required waterjet pressures were measured. Mean thickness of the samples tested within the 0.2Â mm nozzle group was 2.3Â mm (SD 0.7Â mm) and within the 0.6Â mm nozzle group 2.6Â mm (SD 0.9Â mm). The required waterjet pressure to cut samples was between 10 and 12Â MPa for the 0.2Â mm nozzle and between 5 and 10Â MPa for the 0.6Â mm nozzle. Cutting bone or bone cement requires about 3 times higher waterjet pressure (30-50Â MPa, depending on used nozzle diameter) and therefore we consider waterjet cutting as a safe technique to be used for minimally invasive interface tissue removal.
