Publication number: 20210267638Abstract: The present invention relates to an insufflator with integrated smoke evacuation. By virtue of a novel control method of the evacuation volumetric flow rate, the following advantages are achieved. First, a reduction of the pressure in the cavity due to the evacuation is prevented. An empirically determined safety factor is determined, which results in the evacuation volumetric flow rate not exceeding the maximum possible insufflation volumetric flow rate. Second, the exchange volumetric flow rate is limited. It is limited such that the sum of the currently calculated leakage and the evacuation volumetric flow rate does not exceed a defined value. Thus, stress on the patient due to unnecessarily high exchange volumetric flow rates and the associated cooling and drying processes is prevented.Type: ApplicationFiled: July 5, 2019Publication date: September 2, 2021Inventor: Jan BISCHOF

Publication number: 20210267655Abstract: A bone fixation clamp includes first and second clamp members, a stud, and a locking nut. The first member extends along a curve corresponding to an outer surface of a first portion of bone and includes an opening extending therethrough along an axis extending adjacent to the bone. The second member extends along a curve corresponding to an outer surface of a second portion of bone. The stud is receivable within the opening of the first member. The nut includes a threaded channel threadedly engaging a portion of the stud so that, when the first and second members are in the operative configuration, the nut is threadable over the stud to fix the first and second members over bone. The nut includes an anti-loosening feature which, when the nut is threaded over the stud, results in an interference with threading along the stud.Type: ApplicationFiled: February 28, 2020Publication date: September 2, 2021Inventors: Kenny Koay, Peter Fatone, Timothy Reppert
