Gastrointestinal clamp fixation device

Abstract

The invention relates to a clamp type fixing device, and belongs to the technical field of medical apparatuses and instruments. The device comprises a shell, a first push rod, a second push rod, a stretchable flexible shaft, a first clamp finger, a second clamp finger, a first auxiliary clamp and a second auxiliary clamp. One end of the first push rod and one end of the second push rod are each provided with a flange protruding outwards in the radial direction, a sealing ring is arranged on each flange, the shell is partitioned by the two flanges into three independent cavities, the three cavities are communicated with an external hydraulic medium through a power pump, the two ends of the stretchable flexible shaft are connected with the two flanges respectively to form an elastic shaft with the two ends capable of working stretchably, the other end of the first push rod and the other end of the second push rod stretch out of the shell separately, the first auxiliary clamp is arrangedon the first clamp finger, and the second auxiliary clamp is arranged on the second clamp finger. Due to cooperative use of the first clamp finger, the second clamp finger, the first auxiliary clamp and the second auxiliary clamp, clamping is reliable, a foreign matter cannot slip out, the long foreign matter can be fixed, and the application range is enlarged.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a clip-type fixation device in the digestive tract for removing foreign bodies from the digestive tract. Background technique [0002] Gastrointestinal foreign bodies are common abdominal emergency foreign bodies, most of which are swallowed, especially in infants and mental illness or suicide attempts. Most of the foreign bodies can be discharged through the anus, but some patients need surgical treatment because of difficulty in foreign body discharge or complications. According to the circumstances, the operation is divided into two cases: one is a non-invasive operation, which uses a guide tube to enter the digestive tract from the mouth to remove the foreign body, and the other is to directly open an incision in the abdominal cavity to remove it. [0003] However, whether it is invasive or non-invasive, it needs to be fixed by a fixation device when taking it out, s...
