Tissue reinforcement material loader and tissue reinforcement material loading kit
The present invention aims to provide a tissue reinforcement material applicator that enables quick, precise, and easy application of a stick-on tissue reinforcement material to a surgical stapler with less application failure, and a tissue reinforcement material application kit including the tissue reinforcement material applicator. Provided is tissue reinforcement material applicator for securing a stick-on tissue reinforcement material to a surgical stapler, the tissue reinforcement material applicator including a plate-shaped member, the tissue reinforcement material applicator having recesses opposing each other on both surfaces of the plate-shaped member, each recess having a shape corresponding to a shape of a portion of the surgical stapler to which the stick-on tissue reinforcement material is to be applied, each recess being continuous with the same edge of the plate-shaped member, each recess having brush-like protrusions on a bottom surface thereof, each recess having, in a side surface thereof, a securing groove for holding the stick-on tissue reinforcement material therein.
1 . A tissue reinforcement material applicator for securing a stick-on tissue reinforcement material to a surgical stapler,
the tissue reinforcement material applicator comprising a plate-shaped member,
the tissue reinforcement material applicator having recesses opposing each other on both surfaces of the plate-shaped member,
each recess having a shape corresponding to a shape of a portion of the surgical stapler to which the stick-on tissue reinforcement material is to be applied,
each recess being continuous with the same edge of the plate-shaped member,
each recess having brush-like protrusions on a bottom surface thereof,
each recess having, in a side surface thereof, a securing groove for holding the stick-on tissue reinforcement material therein.
2 . The tissue reinforcement material applicator according to claim 1 ,
wherein a bottom of the recesses is different in material from another portion.
3 . The tissue reinforcement material applicator according to claim 1 ,
wherein a bottom of the recesses has an opening in a portion that is to contact a tip of the surgical stapler.
4 . The tissue reinforcement material applicator according to claim 1 ,
wherein the brush-like protrusions have a density of 9 protrusions/cm 2 or greater and 25 protrusions/cm 2 or less.
5 . The tissue reinforcement material applicator according to claim 1 ,
wherein the brush-like protrusions have a length of 0.5 mm or greater and 5 mm or less.
6 . The tissue reinforcement material applicator according to claim 1 ,
wherein the brush-like protrusions become shorter toward ends of the recesses, the ends being on a proximal side of the surgical stapler.
7 . The tissue reinforcement material applicator according to claim 1 ,
wherein each recess becomes wider toward a proximal side of the surgical stapler.
8 . The tissue reinforcement material applicator according to claim 1 , comprising guide walls along both long sides of each recess.
9 . The tissue reinforcement material applicator according to claim 8 ,
wherein each guide wall has an end on a proximal side of the surgical stapler, and the end is inclined downward toward the proximal side.
10 . The tissue reinforcement material applicator according to claim 1 , comprising a grip at an end thereof on a distal side of the surgical stapler.
11 . The tissue reinforcement material applicator according to claim 10 ,
wherein the grip has a cut-out in a side surface on a side of the recesses.
12 . A tissue reinforcement material application kit comprising:
the tissue reinforcement material applicator according to claim 1 ; and
the stick-on tissue reinforcement material held in the securing grooves of the tissue reinforcement material applicator.
13 . The tissue reinforcement material application kit according to claim 12 , comprising a cap at an end thereof on a proximal side of the surgical stapler.
