Problems solved by technology

Such applicator devices are difficult to handle and the end result of the anastomosis is highly dependent on the mutual arrangement between the anastomotic ring device and the applicator device as well as the individual components of the anastomotic ring device (in the case where the anastomotic ring device comprises multiple individual parts) Mutual arrangement between

Embodiment approach

[0043] According to one embodiment, the retaining element 2C of the anastomotic ring device 2 comprises: a proximal annular shoulder 28 adapted to engage with the proximal surface of the proximal compression ring 2B; and protruding distally from the proximal annular shoulder The longitudinal portion forms elastically supported snap teeth 29, which protrude radially outwards from the longitudinal portion to achieve snap engagement with the distal compression ring 2A. The longitudinal portion of the retaining element 2C and the snap teeth define slits or windows 30 which are aligned with the fixed teeth 15 of the retractable retainer 12 so that the retaining element 2C can be moved farther away. The side compression rings 2A engage without interfering with the collapsible retainer 12 .

[0044] The elongated insertion shaft 5 also houses a central access rod 31 , which is slidably housed within the outer tube 21 and has a distal end defining the above-mentioned second connection...

Abstract

A surgical instrument (1) for implanting an anastomotic ring device (2) comprises an anvil (7) including a first connecting part (9) and a seat (15) for receiving a distal compression ring (2A), an actuating member (8) comprising: - one or more seats (22,24) for receiving a proximal compression ring (28) and a retention element (2C); - a second connecting part (17) configured to engage the first connecting part (9) for connecting the anvil (7) with the actuating member (8), wherein the second connecting part (17) is movable to approximate the distal compression ring (2A) towards the proximal compression ring (2B); - an actuating part (24) configured to act on the retention element (2C), the actuating part (24) being movable for moving the retention element (2C) towards and in engagement with the distal compression ring (2A) to connect the compression rings.

Description

technical field [0001] The present invention relates generally to devices and methods for surgically modifying organs and vessels, and more particularly to an applicator for an anastomotic ring device for joining two organs or two parts of the same organ. Parts, for example, of the stomach and small intestine, as well as for connecting blood vessels in certain areas. Background technique [0002] The percentage of the world's population suffering from morbid obesity continues to increase. Severely obese people are at greater risk for heart disease, stroke, diabetes, lung disease and accidents. Due to the impact morbid obesity has on the lives of patients, methods for treating morbid obesity are currently being investigated. [0003] Various non-surgical treatments for morbid obesity have been tried without practically lasting success. Dietary counseling, behavioral modification, wire binding the patient's jaws to close, and pharmacological approaches have all been tried a...
