Pull wire skidproof and antiskid device for medical esophageal stent

Abstract

The invention discloses a pull wire skidproof and antiskid device for a medical esophageal stent. The pull wire skidproof and antiskid device comprises a nose fixing device and an ear fixing device, wherein the nose fixing device and the ear fixing device are connected through an elastic band; the nose fixing device comprises a fixing plate, a nose stuffing pad is arranged on the fixing plate, anda graduation label plate is also rotatably connected to the fixing plate; the ear fixing device comprises a curved stent being conjunctive with the ear outline of a patient, and a rubber soft pad isarranged on the curved stent; and a pull wire locking device is also arranged at one end of the curved stent. The nose fixing device, the ear fixing device and the elastic band are in cooperation, thepull wire skidproof and antiskid device is simple in structure, the pull wire of the esophageal stent of the patient can be fixed, the condition that while in use, the esophageal stent displaces andslips can be avoided, the fine sliding of the pull wire can be shown in a quantification manner, and besides, the pull wire can be prevented from causing pressure sores on the nose and the faces of the patient.

Description

technical field [0001] The invention relates to an external fixation device for a medical esophageal stent, in particular to an anti-slip device for a traction wire of a medical esophageal stent. Background technique [0002] At present, there are many clinical patients with esophageal stenosis due to different reasons. Therefore, it is necessary to place an esophageal stent at the esophageal stenosis to prop up the stenosis. Therefore, a traction wire is often used to connect the esophageal stent, and lead it out from the patient's nasal cavity, and then fix the traction wire to the patient's face or ears. However, due to the daily facial activities of the patient, the tension of the traction wire will change, and it is still easy to cause the esophageal stent to slip. , and because the traction line is thin, it is very easy to cause damage to the patient's nasal mucosa and cause pressure sores on the patient's nose; since there is no mark on the traction line, and the leng...
