The utility model discloses a detailed description:
1. the navigation method comprises the following steps: the instrument combination using the scheme is operated by the following steps during clinical operation:
the first step is as follows: the physician inserts the insertion tube mechanism 2 of the endoscope from one end of a standard nasogastric feeding tube and exposes a small section from the other end. It should be noted that the designed length of the endoscope insertion assembly is greater than the length of a standard feeding tube.
The second step is that: the doctor operates the endoscope, inserts the inserting tube mechanism 2 with the nutrition tube into the nasal cavity of the patient, and enters the stomach of the patient through the cardia;
the third step: the doctor can control the insertion tube mechanism 2 to carry the feeding tube to go further according to the internal image of the human body by observing the picture on the image processor (which is a matched instrument or system), control the snake bone component 23 to bend by the deflector rod, check images in different directions and find the pyloric opening at the same time;
the fourth step: after seeing the pylorus opening, the doctor inserts the guide wire mechanism 3 into the endoscope from the guide wire inlet 1, and after the guide wire soft head 32 penetrates out of the instrument passage opening 245, the doctor continues to control the guide wire mechanism 3 to go deep, and the guide wire soft head 32 firstly probes into the pylorus opening by utilizing the flexibility and the gravity action of the guide wire soft head 32. At this time, because the patient lies down in the clinical operation, the direction of the pyloric opening under the body position is exactly the direction of gravity;
the fifth step: after the head of the guide wire 31 leaves a distance (about 3-4 cm) away from the instrument passage port 245, the doctor controls the insertion tube mechanism 2 to carry the feeding tube to go further, and the insertion tube assembly and the feeding tube synchronously probe into the pylorus port by using the rigid navigation function of the guide wire 31. At this time, the snake bone assembly 23 can be controlled to bend by the deflector rod, and the direction of the guide wire 31 can be further corrected in a small degree. Repeating the above steps, navigating with the guide wire 31 through the insertion tube until the nutrition tube can successfully pass through the pylorus, and placing into duodenum or jejunum;
and a sixth step: the inserting tube mechanism 2 and the guide wire mechanism 3 are drawn out, and the tube placing operation is finished;
with regard to the concept of "navigating each other", it can be understood from two aspects:
(1) The insertion tube of the endoscope is generally relatively soft and, after insertion into the stomach of a human body, the driving force of the physician continues to be applied outside the body without the guide wire mechanism 3, but the distal end portion is difficult to continue to advance, with the result that the curvature of the body portion of the insertion tube assembly in the stomach of the human body increases, but the distal end remains in place. The flexibility of the guide wire soft head 32 and the rigidity of the guide wire mechanism 3 body provide direction navigation for the insertion tube mechanism 2 of the endoscope, under the navigation action, a doctor applies driving force outside the body, and the tip assembly 24 can further advance to a target;
(2) The appropriate bending of the snake bone assembly 23 of the endoscope can correct the direction of advancement of the guide wire mechanism 3, while the insertion tube mechanism 2 also provides an advancement track for the guide wire mechanism 3.
In conclusion, after the ordinary skilled in the art reads the document of the present invention, according to the present invention, the technical solution and technical concept of the present invention do not need creative mental labor to make other various corresponding transformation schemes, which all belong to the protection scope of the present invention.
