Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a gastroscope lower bougie expansion guide wire exchange fixing device for stenosis.
Background
Aiming at the upper gastrointestinal stenosis patient, the currently common treatment means is upper gastrointestinal dilation, the upper gastrointestinal dilation refers to that a guide wire is introduced under the direct vision of an endoscope or by means of the endoscope, a dilator is placed, so that the stenosis is relieved, the problems of malnutrition, dehydration and water and electrolyte imbalance of the patient caused by long-term incapability of eating are solved, and bougie dilation is mainly aimed at unpowered stenosis, neoplastic stenosis, inflammatory stenosis, anastomotic stenosis, postoperative symptom marks and the like.
When the bougie is expanded, firstly, a guide wire is inserted through an endoscope biopsy hole, the front end of the guide wire is inserted into a narrow part under the condition of direct vision of an endoscope, then the endoscope is withdrawn under the condition of keeping the guide wire immovable, then the hollow expanded bougie is sleeved into the guide wire, and the bougie cone part is slowly sent in along the guide wire until the bougie body part covers the narrow part, the expanded bougie is withdrawn after one minute, the guide wire still needs to be fixed, the diameter of the expanded bougie is sequentially and gradually increased, and the narrow part is expanded.
However, during the dilation, after the endoscope is withdrawn, the physician cannot observe the situation inside the patient's body, and once the guidewire is moved, it may cause tissue damage and the dilating bougie cannot reach the stricture, when the guidewire is longer than the initial length outside the body → it may cause dislocation → the dilating duct cannot reach the stricture, and when the guidewire is shorter than the initial length outside the body → it will cause perforation, so the principle of guidewire exchange is required to be performed throughout the dilation process: dilation catheter advance → guidewire fixation don't advance; the expanding catheter goes out → the guide wire synchronously advances at the same frequency, and no matter the expanding bougie advances or retreats, the friction force drives the guide wire to move, so that the existing medical staff often need an assistant to fix the guide wire during operation, and when the expanding bougie is moved by a doctor, the assistant moves the guide wire in the opposite direction at the same frequency to keep the relative position of the guide wire unchanged, and the assistant is difficult to keep accurate cooperation with the doctor in manipulation frequency by experience and feeling. To this end, we propose a gastroscopic stent guidewire exchange fixture for stenosis.
