Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, in particular, a hernia patch cutting mechanism. BACKGROUND

[0002] Hernia refers to the peritoneum supporting internal organs at a location due to surgical injury or pathological changes caused by rupture or weakening, so that the abdominal internal organs protrude outward through the rupture or weakening site to form a local mass. Hernia generally occurs in the inguinal region, waist and navel, etc. It can be divided into inguinal hernia, femoral hernia, umbilical hernia, incisional hernia, lumbar hernia, etc. Hernia generally cannot self-heal, and in severe cases, it affects the patient's walking and normal activities, posing a serious threat to human health and life. If not treated in time, it can lead to intestinal ischemia and necrosis and endanger life.

[0003] The ideal method for treating hernia at present is hernia patch repair, that is, using patch material to cover the damaged part to repair the hernia ring, which has low postoperative recurrence rate, short operation time and fast wound healing. In the 1980s, American surgeons first proposed and adopted tension-free hernia repair surgery to treat hernia. So far, tension-free hernia repair surgery has been widely clinically verified and is considered the safest and most effective treatment method.

[0004] At present, the hernia patch needs to be trimmed according to the different shapes of the patient's tissue in the operation to adapt to different tissue shapes. At present, doctors mostly use scissors to trim the hernia patch, but due to the special material, trimming is difficult, which brings many inconveniences to the operating doctors and reduces work efficiency.
