Multi-ligator device that generates a signal when a ligation ring is released

Multi-ligator device that generates a signal when a ligation ring is released

Official Gazette of the United States Patent & Trademark Office Patents 1234(4), May 23

A multi-ligator device that provides a signal to an operator indicating the release of a ligation ring from the ligator head. Thus, greatly simplifying the use of mechanically decoupled ligator-devices and relieving an operator from having to sense via transmitted vibrations when a ligation ring is detached from a ligator head. The multi-ligator device is constructed using a control unit to operate a ligator head that is connected to the control unit via a flexible shaft. The ligator head supports a plurality of ligation rings that are released by operating the control unit. When a ligation ring is released a signal is generated. The signal can be any one, or a combination, of a mechanical, acoustical, and a visual signal. Additionally, a kit for mounting a ligation ring on a ligator head uses a shaft having a cone-shaped portion to stretch the ligation ring. A lubricant is applied to both the ligation ring and shaft to facilitate the manipulation of the ligation ring. A ring loader is used to push the ligation ring from the tip of the cone shaped portion onto a cylindrical portion of the shaft. Then, a ring pusher is used to push the ligation rings past the cylindrical portion of the shaft and onto the ligator head while the ligator head and the shaft are axially aligned.
