Situation

Transanal insertion of a circular stapler, e.g., for resection with an anastomosis, bears some risks of injuries: 

• Sphincter lesion
• Internal sphincter rupture
• Collision with the mucosa folds
• Risk of perforation

These risks stem mainly from the angular edge of the stapler. 

Eventual consequences

• Up to 36% of patients suffer temporary  of anal incontinence 
• 18% of patients suffer from a sphincter injury 
• Anal incontinence for liquid stool

Situation

Stool residuals are in the bowel and often contaminate the stapler head / stapler seam

Eventual consequences

• Contamination of the seam may contribute to anastomosis leaks

With mprotect
m-protect covers the stapler head and can reduce such contamination

Technical Specs

• 3 sizes: 28/29 – 31/32 – 33/34
• Easy to use
• Compatibable with all standard circular staplers
