Safety locking mechanism for a medical clip device
First Claim
1. An elongated medical clip applying device having a hand holdable housing at a proximal end thereof and a barrel clip-dispenser at a distal end thereof for dispensing squeezable clips onto a mammalian tissue, said device includinga hollow inner sleeve arranged within said housing, said sleeve having a proximal end for receiving a clip feeder cartridge therein;
- a proximal bearing slidably disposed about a proximal circumference of said inner sleeve;
a trigger lever attached to said housing, said trigger lever having a linkage bar thereon connected to a finger for moving said proximal bearing proximally and distally; and
a lock mechanism arranged in said sleeve arranged to deny a clip feeder cartridge entry into said sleeve when said proximal bearing is adjacent said lock mechanism.

Abstract
An elongated medical clip applying device having a hand holdable housing at a proximal end thereof and a barrel clip-dispenser at a distal end thereof is arranged for dispensing squeezable clips onto a mammalian tissue. The device includes a hollow inner sleeve arranged within the housing. The sleeve has a proximal end for receiving a clip feeder cartridge therein. A proximal bearing is slidably disposed about a proximal circumference of the inner sleeve. A trigger lever is attached to the housing, the trigger lever having a linkage bar thereon connected to a finger for moving the proximal bearing proximally and distally. A lock mechanism is arranged in the sleeve to deny a clip feeder cartridge entry into the sleeve when the proximal bearing is adjacent the lock mechanism.

9. A method of locking an elongated medical clip applying device to prevent inadvertent loading of a clip cartridge into an inner sleeve thereof, which sleeve and an extended distal barrel supportively arranged in a housing of said device, comprising:
-
arranging a locking mechanism in a proximal portion of said sleeve in said housing;
pulling a trigger lever on said housing to unlock said locking mechanism upon emptying of clips from a cartridge previously loaded into said sleeve and barrel;
loading a clip cartridge into a proximal end of said sleeve; and
releasing said trigger lever to advance said clip cartridge within said sleeve and barrel of said device. - View Dependent Claims (10, 11, 12, 13, 14)
forming a slot in said inner sleeve at said proximal end thereof, for receipt of said locking mechanism.

11. The method as recited in claim 10, including:
placing a pivotable key in said slot to effect passage of a clip cartridge within said sleeve.
-
12. The method as recited in claim 11, including:
moving a bearing radially adjacent said key in said slot to prevent pivoting of said key from said slot and thereby effectively blocking said sleeve from further loading.
-
13. The method as recited in claim 12, including:
moving said bearing from a position radially adjacent said slot and said key, to permit said key to be pivoted outwardly from said slot thereby permitting entry and passage of a clip cartridge therewithin.
-
14. The method as recited in claim 12, including:
pivoting said locking mechanism into engagement with a hole in said clip cartridge to lock said cartridge in said clip applying device.
