Jaw restraint
A jaw restraint is provided to temporarily secure an anvil assembly relative to a cartridge assembly during shipping. The jaw restraint generally includes a body portion having an upper arm for releasably securing the anvil assembly and a lower arm for releasably securing the cartridge assembly. An inwardly projection is provided between the upper and lower arms. The anvil assembly is secured between the upper arm and the inwardly directed projection and the cartridge assembly is secured between the lower arm of the inwardly directed projection. One or more finger members extending proximally from the body portion may be provided to facilitate biasing the upper arm away from the lower arm to release the anvil and cartridge assemblies from the jaw restraint. The jaw restraint may be provided with structure for engagement with shipping packaging.
1. A jaw restraint in combination with a surgical stapler, the jaw restraint comprising:
a first arm releasably attachable to a first jaw of the surgical stapler;
a first arcuate portion extending from the first arm;
a second arm releasably attachable to a second jaw of the surgical stapler;
a second arcuate portion extending from the second arm;
a projection directed inwardly between the first arm and the second arm; and
a first finger member and a second finger member, wherein both the first and second finger members extend in an opposite direction of the projection,
the first arcuate portion connecting the first arm to the projection, and the second arcuate portion connecting the second arm to the projection, wherein relative movement between the first finger member and the second finger member urges the first and second arms to pivot about the projection,
the projection is interposed between the first jaw of the surgical stapler and second jaw of the surgical stapler.
2. The jaw restraint as recited in claim 1 , wherein the movement of the first and second finger members towards each other urges the first and second arms to pivot away from each other.
3. The jaw restraint as recited in claim 1 , wherein the first arm defines a first recess, the second arm defines a second recess, and the first and second recesses are oriented towards one another.
4. The jaw restraint as recited in claim 1 , wherein the first arm includes an inwardly directed lip.
5. The jaw restraint as recited in claim 4 , wherein the inwardly directed lip includes an enlarged distal end.
6. The jaw restraint as recited in claim 1 , wherein the projection is formed from a flexible material.
7. The jaw restraint as recited in claim 1 , wherein the first and second arms are pivotable about the projection between a first jaw retaining position and a second jaw releasing position.
8. The jaw restraint as recited in claim 2 , wherein movement of the first and second finger members towards each other transitions the jaw restraint from a first jaw retaining position and a second jaw releasing position.
9. A jaw restraint in combination with a surgical stapler, the jaw restraint comprising:
a body portion having:
a first arm releasably attachable to a first jaw of the surgical stapler;
a first arcuate portion extending from the first arm;
a second arm releasably attachable to a second jaw of the surgical stapler;
a second arcuate portion extending from the second arm;
a projection directed inwardly between the first arm and the second arm;
a finger member extending in the opposite direction of the projection, the finger member extending from the first arcuate portion;
the first arcuate portion connecting the first arm to the projection and the second arcuate portion connecting the second arm to the projection; and
the projection is interposed between the first jaw of the surgical stapler and second jaw of the surgical stapler.
10. The jaw restraint as recited in claim 9 , wherein in an opposite arm defines a first recess facing a first direction, and the second arm defines a second recess facing the first direction.
