Appl. No.:

17/240381

Inventors:

- Zug, CH
Katherine J. Schmid - Cincinnati OH, US
Harry Randolph Adams - Fort Thomas KY, US

Assignee:

Cilag GmbH International - Zug

International Classification:

A61B 17/34
A61B 17/02

Abstract:

A trocar assembly that includes a trocar and a seal cartridge configured to be releasably coupled to the trocar. The seal cartridge includes a top cap that includes a main body and a latch ring. The latch ring is grounded to the main body at a first angular position and has a latch located at a second angular position angularly offset from the first angular position. Applying a radial load on the latch causes the latch ring to flex in torsion at an intermediate portion that angularly interposes the first and second angular positions.

International Classification:

A61B 17/34

Abstract:

A trocar assembly includes a seal assembly that maintains insufflation pressure when sized seal cartridges are removed and replaced. The trocar assembly includes a housing that defines a working chamber, and a cannula distally extends from the housing and defines a lumen that communicates with the working chamber. The seal cartridge is arranged within the working chamber, and may include one or both of a proximal seal assembly and a distal seal assembly arranged distally from the proximal seal assembly, and may further include a bushing extending distally from a distal end of the seal cartridge and into the lumen. A tertiary seal may also be positioned within the working chamber distal to the seal cartridge, such that the bushing extends through the tertiary seal when the seal cartridge is received within the working chamber.
