Abstract
A novel device for applying hemostatic clips in laparoscopic surgery incorporates a distal hook into a multiple-firing titanium clip applier. The hook may be used for blunt dissection of tissue, and to displace and control ducts and vessels during clip application. A single instrument may be used to achieve hemostasis in areas that are difficult to reach, and past pointing problems encountered with straight on clip appliers are alleviated. Comparative testing of the holding force of the curved clips used with this device versus the straight clips used in conventional multiple-clip appliers demonstrated a higher mean pull-off force of 0.473 lbs versus 0.33 lbs. Clinical application of the device in laparoscopic procedures including cholecystectomy, vaginal hysterectomy, Nissen fundoplication, vagotomy, varicocelectomy, and lymphadenectomy show the utility of the hook clip applier.
