DESCRIPTION 

Endoscopically placed clips have become one of the most important accessories while performing therapeutic endoscopy. O-CLIP is an endoscopic mechanical device made from an electrically insulated material, which is passed via the biopsy/suction channel during an upper or lower endoscopy. Design will be like the previously made ENDOGRIP forceps but will add a mechanism to detach the tip of ENDOGRIP forceps making it the O-CLIP. 

NEED FOR DEVELOPING THIS DEVICE

1. O-CLIP is an endoscopic mechanical clipping device made of electrically insulated material which is used to achieve hemostasis through direct compression or tamponade of vessels and tissue approximation of bleeding stigmata. The shape of these clips helps to take the contour of the pedicle easily and thereby achieving hemostasis. 

1. O-CLIP comes in different diameters to help with different sizes of polyp pedicles.

1. O-CLIP has a unique design due to shape and malleability which helps in achieving hemostasis. The deployment of the O-CLIP is like deploying a regular endoclip which will make it easier to use. 

DESCRIPTION

1. The pedunculated polyp has pedicle that usually has a feeding vessel and therefore has a high potential for post-polypectomy bleeding. To prevent excessive bleeding, a loop ligating device like an endoloop (Polyloop; Olympus America, Inc.) can be deployed around the pedicle to act as a tourniquet to prevent bleeding after the polyp is removed. 

1. The technique of deploying an endoloop involves opening the loop, then maneuvering it around the polyp, and bringing it down to the level of the pedicle The tightened endoloop around the stalk acts like a tourniquet, tamponading the vessel in the pedicle. 

1. This deployment of the endoloop can be challenging sometimes, as the endoloop is floppy and not as stiff as a snare. Also, it is important to position the endoloop on the stalk at some distance away from the lower edge of the polyp so that polypectomy can be performed above the endoloop. After polypectomy, the endoloop should still be securely tight around the remaining pedicle. 

1. Compared to the endoloop, the unique design of O-CLIP with its shape, malleability, and ease of deployment can be a great addition to achieving hemostasis in therapeutic endoscopy. 

1. O-CLIP achieves hemostasis through direct compression or tamponade of vessels and tissue approximation of bleeding stigmata. 

MECHANISM of the O-CLIP

1. O-CLIP is passed via the biopsy/suction channel. 

1. Made of electrically insulated material, it measures standard size of 5 French in size. The distal end of the opened clip has different sizes which can be used based on the size of the pedicle.
