TST33 – Tissue Selecting Therapy Stapler
Single use internal stapler
Circular Stapled hemorrhoidopexy (CSh), characterized by a circular incision of the rectal mucosa,[1] is an effective technique for treating prolapsing hemorrhoids. However, the incidence of postoperative urgency and anal stenosis was reported to be as high as 40 %[2] and 6 %,[3]respectively.
Removal of large areas of the anoderm and hemorrhoidal rectal mucosa, without the sparing of adequate mucocutaneous bridges, can lead to scarring and a progressive chronic stricture.[3], [4]
These complications, might be related to the presence of too many staples in the sensitive lower rectum and the nature of the staple line (full circumference).[5]
- Permanent parallel compression
- Anti-retrieval lock technology
- DAO unit
- ASL – Built-in Automatic Safety Lock prevents accidental mis-firing
- Adjustable staple closure height ranging from 1 mm to 2.5 mm
