Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to a bougie expanding guide wire exchange fixing device under a gastroscope for stenosis.
Background
For patients with upper gastrointestinal stenosis, the current common treatment method is upper gastrointestinal dilation, which is to introduce a guide wire under direct vision of an endoscope or by means of the endoscope, and place a dilator, so that the stenosis is relieved, the problems of malnutrition, dehydration and water and electrolyte imbalance caused by long-term incapacity of eating of the patients are solved, and the bougie dilation is mainly aimed at unpowered stenosis, neoplastic stenosis, inflammatory stenosis, anastomotic stoma stenosis, postoperative scars and the like.
When the bougie is expanded, a guide wire is inserted through an endoscope biopsy hole, the front end of the guide wire is inserted into a narrow place under the direct vision of an endoscope, then the endoscope is withdrawn under the condition of keeping the guide wire still, the hollow expanded bougie is sleeved into the guide wire, the bougie cone part is slowly fed in along the guide wire until the bougie body part covers the narrow part, the expanded bougie is withdrawn after one minute, the guide wire still needs to be fixed, the diameter of the expanded bougie is gradually increased in sequence, and the narrow part is expanded.
However, during the expansion, after the endoscope is withdrawn, the medical staff cannot observe the condition in the patient, once the guide wire moves, the tissue is possibly damaged, the expansion bougie cannot reach the narrow part, when the guide wire is longer than the initial external length, the expansion pipe can be displaced and removed, the expansion pipe cannot reach the narrow part, and when the guide wire is shorter than the initial external length, the anti-displacement causes perforation, so that the guide wire exchange needs to be performed in the whole expansion process according to the principle: expanding the catheter, fixing the guide wire, and not advancing; the expanding catheter goes out to the guide wire to synchronously go in the same frequency, and because the expanding probe can have friction force to drive the guide wire to move no matter when advancing or backing, the conventional medical staff often needs an assistant to fix the guide wire when operating, and when the doctor moves the expanding probe, the assistant moves the guide wire in the opposite direction of 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 operation in the aspect of manipulation frequency by experience and feel. To this end, we propose a stenotic gastroscopic bougie-dilating guidewire exchange fixture.
