Publication number: 20230165620Abstract: A cryosurgical instrument includes a feed line for conveying fluid into an expansion chamber. The feed line has a capillary line section that terminates in the expansion chamber and forms an aperture for the fluid to undergo the Joule-Thomson effect. The flow cross-section of the feed line decreases in at least one transition section of the feed line in the form of a funnel. Following each transition section there preferably follows a step section, in which latter section the flow cross-section is preferably largely constant. The last step section is preferably formed by the capillary line section. Due to the acceleration of the fluid in the transition sections and the abating of pressure fluctuations in the capillary tube section and, optionally in the additional step sections, the expansion range in the expansion chamber is increased, without impeding the backflow of the expanded gas out of the expansion chamber.Type: ApplicationFiled: January 20, 2023Publication date: June 1, 2023Inventors: Achim Brodbeck, Joerg Kronenthaler, Marcus Adler, Hanna Andel, Klaus Fischer

Patent number: 11426187Abstract: The forceps instrument includes a central pull-push member formed by transmission and actuating elements. The central push-pull member opens and closes the branches, and also acts as a tissue abutment that is variable based on the degree of closure of the branches. The variable tissue abutment may be configured as a slider element and is adjustable proportionally to the opening angle of the branches. When grasped, the vessels are brought proximally. The tissue abutment acts as a spacer between the hinge region and the grasped material. While the branches are being closed, the vessel is held stationary and compressed. During compression, expansion of the vessel occurs axially in distal and proximal directions. Due to the receding of the variable tissue abutment during the closing operation, room is created for the grasped material to escape. Tissue accumulations can thus be restricted and overstressing of the tissue can be counteracted.Type: GrantFiled: June 7, 2019Date of Patent: August 30, 2022Assignee: Erbe Elektromedizin GmbHInventors: Achim Brodbeck, Matthias Voigtlaender, Bernhard Nold, Tim Closs
