Title: Washing system for endoscopic surgical therapy
Inventor: TIMS JERRY L
IPC: A61B17/00
Filed: 2000-09-25
Abstract: PROBLEM TO BE SOLVED: To reduce a cost by exchangeably constituting a portion of a pump. SOLUTION: The washing system for use during an endoscopic or minimum penetration type surgical therapy is disclosed. Both of a vacuum and a pressurized washing liquid are continuously supplied to a trumpet valve for prompt use during surgery. A pump for supplying the pressurized washing liquid is a recycling motor but has a throw-away head which is exchangeable during the procedure. If there is a request for the washing liquid in an initial period, a control circuit automatically decreases the supply voltage to the pump. When (a) there is no request for washing upon lapse of a second period longer than the first period and (b) the voltage to the pump is not decreased, the voltage to the pump is not decreased or the pump is stopped. The washing system is supplied in a kit form and the parts are exchanged during the procedure included therein.

Filed: 2000-11-27
Abstract: PROBLEM TO BE SOLVED: To obtain technology which can speedily perform parameter extraction for obtaining a real solution as a parameter extracting method for a physical property model which can sufficiently decrease the values of errors that feature values in an error function have by the feature values even if the values of the errors have large and small differences. SOLUTION: The error function S is defined by summing up the values obtained by dividing the squares of differences between respective feature values giy and functions fy (vi, P) corresponding to them by variance σiy2 of observation values of multiple samples over multiple external factor groups. Even if the errors that the respective feature values have are different, they are divided by the variance σiy2 by the feature values and then the influence of variance and deviation of the observation values included in the errors can be corrected. Further, the dependence of values of the error function S upon a χ2 distribution is used to verify whether or not the function fy (vS, P) can reproduce the observation values and when so, the current parameter group P is extracted as a parameter group which gives the minimum value of the error function S.
