Background

Echinococcosis (echinococcosis) is a chronic parasitic disease caused by infection of human with echinococcus larvae (echinococcosis). The clinical manifestations of this disease vary depending on the location, size and presence of complications of hydatid cyst. The echinococcosis combined sac sequentially comprises a fibrous layer, a horny layer, a hair growth layer, an ascon and a sac fluid from outside to inside, and due to the protective action of the fibrous layer and the horny layer, the conventional drug therapy has no effect in the treatment of the echinococcosis. At present, the main treatment modes are complete excision of the outer capsule (liver and fibrous layer) and excision of the inner capsule (horny layer and hair growing layer) under the condition of opening the abdomen.

At present, the echinococcus hepatica endocyst extirpation adopts self-made suction tubes (comprising a number 26 latex tube, a 50ml syringe needle and a 20ml syringe needle), firstly uses the suction tube to suck the echinococcus cyst fluid, extracts the suction tube, enlarges the incision, takes out cyst skin (not inactivated) and then injects hypertonic saline into the cyst through a water injection tube to kill echinococcus. The suction tube is self-made in the process, occupational exposure risks exist, the hydatid is easily exposed in the inserting and pulling process, the abdominal cavity is planted, the incision is enlarged, and the non-inactivated cyst skin is taken out, so that the hydatid is also easily exposed to the abdominal cavity.
