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 As a user applies a pulling force to the manipulation assembly, the internal tubing member is slidably withdrawn from the external tubing member to expose a visible force scale that indicates the level of pulling force being applied by the user.

Claims

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.

2. The anastomosis training device of claim 1, further comprising:

an anchor device for attachment to a surface, the anchor device attaching to the retention member for fixing the training device relative to the surface.

3. The anastomosis training device of claim 2, wherein the anchor device comprises a vacuum cup and a retention hook, said vacuum cup sealingly engaging the surface.

4. The anastomosis training device of claim 3, wherein the retention member comprises an eye bolt, and wherein said eyebolt is retained by the retention hook.

5. The anastomosis training device of claim 1, wherein the internal tube member comprises an exterior surface having a visible force scale, said visible force scale being viewable as a pulling force is applied to the manipulation member and said internal tube member is slidingly withdrawn from the external tube member.

6. The anastomosis training device of claim 5, wherein the visible force scale comprises a plurality of spaced apart, circumferential grooves on the exterior surface, each groove representing a force increment.

7. The anastomosis training device of claim 6, wherein the visible force scale further comprises at least three different colors, wherein a first color represents application of insufficient force, a second color represents an application of optimal force and a third color represents an application of excessive force.

8. The anastomosis training device of claim 1, wherein the manipulation member simulates an anastomosis manipulation member including a plurality of access ports.
