Publication number: 20230270335Abstract: In various aspects, a microsurgical apparatus disclosed herein includes a shaft having a shaft distal end, a shaft proximal end with a handle mounted to shaft proximal end. The microsurgical apparatus includes a tool package having an actuator at a tool package proximal end of the tool package and a tool at a tool package distal end of the tool package. The actuator cooperates mechanically with the tool. A sleeve lumen disposed within the tool package slidably receives the shaft for releasable lockable engagement of the tool package proximal end with the handle and with the shaft distal end being generally coextensive with the tool package distal end. Light source(s) and image sensor(s) located proximate the shaft distal end allow viewing of regions distal to the shaft including the tool when the tool package is mounted to the shaft. Exemplary methods of use of the microsurgical apparatus are also disclosed herein.Type: ApplicationFiled: May 4, 2023Publication date: August 31, 2023Inventor: MAREK SEKOWSKI

Patent number: 10835360Abstract: A periodontal endoscope includes an imaging handle having an imaging end that supports a camera sensor and an introducer including an introducer blade such that the introducer blade is selectively rotatable about the camera sensor for engaging gingival tissue in the field of view for any rotational orientation of the introducer blade relative to the camera while illuminated by an optical fiber bundle. An automatic illuminance controller controls an illumination light source at least within each frame as the frame is scanned based on dynamic range of the camera sensor such that high intensity areas of the frame receive a reduced amount of illumination light by reducing the illumination drive signal as compared to low intensity areas of the frame which receive an increased amount of illumination light by increasing the illumination drive signal relative to the high intensity areas.Type: GrantFiled: March 27, 2017Date of Patent: November 17, 2020Assignee: Research and Development International CorporationInventor: Marek Sekowski

Publication number: 20200229702Abstract: In various aspects, the microsurgical apparatus disclosed herein includes a shaft having a shaft distal end, a shaft proximal end with a handle mounted to shaft proximal end. The shaft may have a constant cross-section. In various aspects, the microsurgical apparatus includes a tool package having an actuator at a tool package proximal end of the tool package and a tool at a tool package distal end of the tool package. The actuator cooperates mechanically with the tool to alter the tool between a disengaged position and an engaged position as the actuator is altered between a first actuator position and a second actuator position, in various aspects. A sleeve disposed within the tool package forms a sleeve lumen that extends generally between the tool package proximal end and the tool package distal end, and the sleeve lumen slidably receives the shaft for releasable lockable engagement of the tool package proximal end with the handle, in various aspects.Type: ApplicationFiled: January 19, 2019Publication date: July 23, 2020Inventor: MAREK SEKOWSKI
