Abstract
Abstract Disclosed is a method of suturing the abomasum of a ruminant animal. The method includes inserting one end of a cannula through the belly of the animal and into the lumen of the abomasum. One end of a suture and toggle attached thereto is inserted through a bore of the cannula and into the lumen by travel of a trocar through the bore behind the toggle. The extent of the travel of the cannula into the lumen is limited by providing an outer end of the cannula with a flange that engages the hide of the animal and the travel of the trocar through the bore of the cannula is limited by providing the trocar with a handle that abuts against the flange of the cannula.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
230 words
A method of suturing the abomasum of a ruminant animal comprising: inserting one end of a cannula through the hide of the animal and into its lumen through a wall of the abomasum; inserting one end of a suture and toggle attached thereto in a bore of the cannula and directing the toggle into the lumen of the animal by travel of a forward pointed end of a trocar through said bore behind the toggle, the trocar having an axial slot for receiving the suture and containing it in and along the length of the cannula, and the cannula having an outer end for location outside of the animal; limiting the extend of the travel of the cannula into the lumen by providing the outer end of the cannula with an integral flange that engages the hide of the animal and prevents the cannula from slipping completely into the lumen; limiting the travel of the trocar through the bore of the cannula by providing the trocar with a handle that abuts against the flange of the cannula after the toggle clears the cannula in the lumen and the forward end of the trocar behind the toggle enters the lumen beyond the end of the cannula; removing the cannula and trocar from the lumen; and using the toggle and suture to tie the stomach wall of the animal to its side.
Claim 2
Independent Claim

A method of suturing the abomasum of a ruminant animal comprising: inserting one end of a cannula through the hide of the animal and into its lumen through a wall of the abomasum; inserting one end of a suture and toggle attached thereto in a bore of the cannula and directing the toggle into the lumen of the animal by travel of a forward pointed end of a trocar through said bore behind the toggle, the trocar having an axial slot for receiving the suture and containing it in and along the length of the cannula, and the cannula having an outer end for location outside of the animal; limiting the extend of the travel of the cannula into the lumen by providing the outer end of the cannula with an integral flange that engages the hide of the animal and prevents the cannula from slipping completely into the lumen; limiting the travel of the trocar through the bore of the cannula by providing the trocar with a handle that abuts against the flange of the cannula after the toggle clears the cannula in the lumen and the forward end of the trocar behind the toggle enters the lumen beyond the end of the cannula; removing the cannula and trocar from the lumen; and using the toggle and suture to tie the stomach wall of the animal to its side.
Claim 3
Dependent Claim

The method of claim 1 including: inserting a second suture and toggle in the lumen of the animal using the steps of claim 1 and in a manner that locates the two sutures with ends located outside of the animal; and tying the outside ends of the two sutures together to secure the wall of the abomasum to one side of the animal.
