A hand-operable surgical clip applicator, the applicator comprising: a barrel having a first end and a second end, the second end formed as a first crimping surface and being able to accommodate a surgical clip; a crimping lever, the crimping lever pivotally connected to the barrel, the crimping lever having a second crimping surface and an opening peg integrally formed therewith, the second crimping surface being in opposition to the first crimping surface, the first crimping surface and the second crimping surface being biased away from one another; and a pushrod, which may abut, and in use does abut, the crimping lever and constrains the opening peg, the pushrod being slidably located within the barrel; wherein the hand-operable surgical clip applicator is configured such that movement of the pushrod towards the second end of the barrel causes the pushrod to push the crimping lever, further causing the second crimping surface to close onto the first crimping surface, thereby in use urging a surgical clip from an open position towards a closed position, the pushrod comprising a transfer rod and a pusher, the pusher having a stop face, the transfer rod and pusher being slidably located within the barrel, the pusher including a slot through which a portion of the opening peg extends, wherein movement of the pushrod away from the second end of the barrel causes a surface formed by the slot in the pusher to pull the opening peg, further causing the second crimping surface to open away from the first crimping surface, and the hand-operable surgical clip applicator being characterised by the transfer rod and pusher being releasably connected together by a bayonet joint, and the pusher abutting the crimping lever and constraining the opening peg of the crimping lever. a barrel having a first end and a second end, the second end formed as a first crimping surface and being able to accommodate a surgical clip; a crimping lever, the crimping lever pivotally connected to the barrel, the crimping lever having a second crimping surface and an opening peg integrally formed therewith, the second crimping surface being in opposition to the first crimping surface, the first crimping surface and the second crimping surface being biased away from one another; and a pushrod, which may abut, and in use does abut, the crimping lever and constrains the opening peg, the pushrod being slidably located within the barrel; wherein the hand-operable surgical clip applicator is configured such that movement of the pushrod towards the second end of the barrel causes the pushrod to push the crimping lever, further causing the second crimping surface to close onto the first crimping surface, thereby in use urging a surgical clip from an open position towards a closed position, the pushrod comprising a transfer rod and a pusher, the pusher having a stop face, the transfer rod and pusher being slidably located within the barrel, the pusher including a slot through which a portion of the opening peg extends, wherein movement of the pushrod away from the second end of the barrel causes a surface formed by the slot in the pusher to pull the opening peg, further causing the second crimping surface to open away from the first crimping surface, and the hand-operable surgical clip applicator being characterised by the transfer rod and pusher being releasably connected together by a bayonet joint, and the pusher abutting the crimping lever and constraining the opening peg of the crimping lever.
