Abstract

A surgical clip applicator (1) having a handle (2) with an operating device (4) and a shaft tube (6) mounted to the handle (2) is disclosed in which is arranged a connecting rod (8) longitudinally displaceable by the operating device (4) and restorable by spring tension, a clip magazine (12) containing several clips (10) and receivable in the shaft tube (6), and a jaw member (14) for closing the clips (10) at the distal and (16) of the shaft tube (6).

Claims

1. In combination:

(a) a surgical clip applicator comprising;

a handle,

a shaft tube mounted to the handle and defining a clip magazine-receiving region at a distal end thereof,

a connecting rod movably positioned within the shaft tube, the connecting rod extending into the handle, and a jaw member positioned at a distal end of the shaft tube; and

(b) a clip magazine containing a plurality of clips and a clip reloader,

wherein the clip magazine is removably received within the clip magazine-receiving region at the distal end of the shaft tube, the connecting rod includes a projection that engages a resilient coupling member which is operatively connected to the clip reloader so that distal movement of the connecting rod may effect distal movement of the clip reloader, and the connecting rod includes at least one camming face at a distal end thereof so that distal movement of the connecting rod may effect camming of the jaw member.

2. The combination of claim 1, wherein the shaft tube includes a pawl adjacent the clip magazine-receiving region and wherein the pawl releasably maintains the clip magazine in engagement with the shaft tube.

3. The combination of claim 1, wherein the surgical clip applicator has a substantially semicircular cross-section in the clip magazine-receiving region and the clip magazine has a substantially semicircular cross-section.

4. The combination of claim 1, wherein the surgical clip applicator is fabricated from metal.

5. The combination of claim 1, wherein the clip magazine further comprises an inspection window.
