Description
Technical Field
The invention relates to the technical field of medical equipment, in particular to a special fixer capable of recovering an esophageal stent line.
Background
Cancer is one of ten major causes of death of Chinese, and among them, cancers of digestive tract including esophagus, stomach and colorectal cancer cause high death rate every year. These cancers often cause a blockage of the digestive tract, which affects feeding or defecation, and in the past, patients often have solved their nutritional or defecation problems by way of an entero-or gastrostomy when faced with a blockage of the digestive tract and the patient is unable to remove the tumor surgically or otherwise. The biggest problem of esophageal cancer is obstruction, but gastrostomy still cannot allow patients to eat food from mouth, and in order to allow patients to eat food from mouth to meet desire of mouth, esophageal stents for opening tumor obstruction are developed. Early esophageal stents were made of harder plastic, patients suffered from obvious pain after placement and had many complications, and patients had low acceptance, in recent years, due to the progress of medical materials, many alloy substances were applied to medical treatment, and an alloy metal stent was a nickel-titanium alloy product that can be self-expanded, has elasticity, flexibility and high memory, and was applied to esophageal tumors, opening the door for widespread application of esophageal stents with low pain and low complications.
Because the requirement on the position for placing the esophageal stent is very high, in order to ensure the accuracy of the position for placing the esophageal stent, the recyclable esophageal stent is generally adopted at present. The recyclable esophageal stent is designed for benign stenosis and short-time fistula plugging, the stent is fully covered with a film, and the film exceeds the end edge of the stent, so that the occurrence of irritant hyperplasia is reduced to the maximum extent; in order to facilitate the recovery and the adjustment of the position when the stent is placed in, the generally recoverable esophageal stent is connected with a recovery wire, so that the expanded end edge of the stent can be conveniently tightened when the stent is recovered, and the stent is convenient to recover.
After the recoverable esophageal stent is placed into a patient, one end of the recovery line is led out from the corner of the mouth of the patient along the esophagus of the patient, and then the recovery line is fixed on the side face of the patient by using an adhesive tape, so that the influence of the recovery line on the feeding of the patient is avoided as much as possible, and the esophageal stent is convenient to recover; however, since the recovery thread is led out from the corner of the mouth of the patient, discomfort and injury can be caused to the corner of the mouth of the patient, and after a long time, the recovery thread is likely to be damaged due to the fact that the patient eats and chews the recovery thread.
