Surgical clip applicator
First Claim
1. A surgical clip applicator adapted for the application of a surgical clip within the human body, the surgical clip applicator comprising:
- a ram;
a ram housing having proximal and distal ends and at least partially surrounding the ram;
a trigger housing including a trigger having an open position and a closed position, the trigger housing being mounted to the proximal end of the ram housing, the ram extending partially into the trigger housing and operatively connected to the trigger, the trigger spaced a first distance from the trigger housing in the open position and spaced a second distance from the trigger housing in the closed position, the first distance being larger than the second distance, a retaining mechanism retaining the trigger with respect to the trigger housing between the open and closed positions;
a cartridge removably mounted into the distal end of the ram housing, the cartridge including a plurality of surgical clips,wherein mounting the cartridge into the distal end of the ram housing urges at least a portion of the ram into the trigger housing set the trigger in the open position.

Abstract
A surgical clip applicator for applying surgical clips to body tissue includes an elongated ram housing that has proximal and distal ends and at least partially encloses a ram. A trigger housing includes a trigger that has an open position and a closed position. The trigger housing is mounted to the proximal end of the ram housing. The ram extends partially into the trigger housing and is operatively connected to the trigger. The trigger is spaced a first distance from the trigger housing in the open position and spaced a second distance from the trigger housing in the closed position. The first distance being larger than the second distance. A cartridge is removably mounted into the ram housing. The cartridge includes a plurality of the surgical clips. A retaining mechanism retains the trigger with respect to the trigger housing between the open and closed positions. Mounting the cartridge into the distal end of the ram housing urges at least a portion of the ram into the housing to set the trigger in the open position.

2. A surgical clip applicator adapted for the application of a surgical clip to body tissue, the surgical clip applicator comprising:
-
a ram; an elongated ram housing having proximal and distal ends and at least partially enclosing the ram; a trigger housing including a trigger having an open position and a closed position, the trigger housing being mounted to the proximal end of the ram housing, the ram extending partially into the trigger housing and operatively connected to the trigger, the trigger spaced a first distance from the trigger housing in the open position and spaced a second distance from the trigger housing in the closed position, the first distance being larger than the second distance, the trigger urging the ram toward the distal end of the ram housing as the trigger is moved from the open position to the closed position, a retaining mechanism retaining the trigger with respect to the trigger housing between the open and closed positions; a cartridge removably mounting into the distal end of the ram housing, the cartridge including a plurality of surgical clips and a pair of opposed jaws extending from a distal end of the cartridge, a clip driver for advancing one of the plurality of surgical clips at a time into the jaws when urged toward the distal end of the cartridge by the ram and a jaw driver for closing the jaws to pinch the one surgical clip when the jaw driver is urged toward the distal end of the cartridge by the ram, wherein mounting the cartridge to the distal end of the ram housing urges at least a portion of the ram into the trigger housing to set the trigger in the open position. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A surgical clip cartridge for use with a surgical clip applicator adapted for the application of a surgical clip to body tissue, the surgical clip applicator having an elongated ram housing having proximal and distal ends and including a ram, a trigger housing mounted to the proximal end of the ram housing, the ram extending partially into the trigger housing and operatively connected to a trigger having an open position and a closed position, the trigger spaced a first distance from the trigger housing in the open position and spaced a second distance from the trigger housing in the closed position, the first distance being larger than the second distance, the trigger urging the ram toward the distal end of the ram housing as the trigger is moved from the open position in which the trigger is enabled to initiate the application of a clip to the closed position in which the clip has been applied, the cartridge removably mounted into the distal end of the ram housing, the cartridge comprising:
-
a cartridge housing; a plurality of surgical clips; a pair of opposed jaws extending from a distal end of the cartridge housing; a clip driver disposed within the cartridge housing for advancing one of the plurality of surgical clips at a time into the jaws when urged by the ram; and a jaw driver disposed within the cartridge housing for closing the jaws to pinch the one surgical clip when urged by the ram, wherein a alignment member releasably retains the clip driver and the jaw driver in a mounted position such that the clip driver and the jaw driver are stationary with respect to each other and releases the clip driver and jaw driver in an active position once the cartridge is mounted into the ram housing and the trigger is moved out to the open position. - View Dependent Claims (17, 18, 19, 20)
