ANASTOMOSIS DEPLOYMENT FORCE TRAINING TOOL
First Claim
1. An anastomosis training device, comprising:
- a housing portion comprising an external tube member and an internal tube member, the internal tube member includes an internal tube lumen connected to an internal tube recess, the internal tube member slidingly residing with the external tube member;
a spring member mounted within the internal tube recess;
a distal wire member connected to a distal end of the spring member, the distal wire member extending through a distal tube portion, wherein the distal wire member is fixedly attached to a retention member; and
a proximal wire member connected to a proximal end of the spring member, the proximal wire member extending through a proximal tube portion wherein the proximal wire member is fixedly attached to a manipulation member.

Abstract
An anastomosis training device and related methods of use that provides medical professionals with real-time feedback of pulling force. The anastomosis training device can include a housing portion, a spring member, a proximal catheter portion and a distal catheter portion. The housing portion can include an external tubing member that slidingly retains an internal tubing element and the spring member. A proximal wire assembly attaches the spring member to a manipulation assembly and a distal wire assembly attaches the spring member to a retention member that allows the anastomosis training tool to be anchored to a suitable surface. As a user applies a pulling force to the manipulation assembly, the internal tubing member is slidably withdrawn from the external tubing member to expose a visible force scale that indicates the level of pulling force being applied by the user.

9. A method for simulating an anastomosis procedure with a training device, comprising:
-
providing an anastomosis simulation device having a fixation end, a housing portion, and a manipulation end; anchoring the fixation end to a non-movable surface; and applying a pull force to the manipulation end such that an internal tube member within the housing portion is slidably withdrawn such that a visible force scale on the internal tube member is visible, said visible force scale being representative of the applied pull force. - View Dependent Claims (10, 11, 12)
