Abstract

The invention discloses a disc-shaped gastrostomy tube extubation device and an extubation method, wherein the extubation device comprises a guiding pipe, a probe and a position clip member; a guidingwire is arranged inside the guiding pipe and the head of the guiding pipe is magnetic; the probe is made from soft magnet; the position clip member comprises a position clip member body and a first wiring; one end of the position clip member body is connected with the first wiring. In this way, the disc-shaped gastrostomy tube extubation device and the extubation method are provided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a disc-shaped gastrostomy tube extubation device and an extubation method. Background technique [0002] With the development of endoscopic treatment technology, Persutaneous Endoscopic Gastrostomy (PEG) has been widely accepted and used. Enteral nutrition for patients with loss of swallowing function or swallowing obstruction through PEG is in line with the physiological state, Compared with the traditional open gastrostomy operation, it has the advantages of less trauma, safety, convenience, and low cost, avoiding surgical risks, and the catheterization time can be as long as 3-5 years or more. It is mainly suitable for patients who cannot import food due to various reasons, need long-term nutritional support and indwelling nasogastric tube for more than 1 month, or cannot tolerate nasogastric tube, including various oral head and neck tumors, craniocerebral trauma, cerebrovascul...
