Description

Technical Field

[0001] The invention belongs to the technical field of in vivo cannulation, and in particular relates to a visualized bile and pancreas appendix cannulation system. Background Art

[0002] With the advancement of medical technology, imaging medicine can help doctors understand the patient's internal condition. For example, doctors can use an endoscope to obtain images of the corresponding parts of the patient's body.

[0003] In a Chinese patent with publication number CN109077695A, an endoscopic cannula is mentioned, including a cannula body and a plurality of camera wires for connecting to an endoscope camera. Along the circumference of the cannula body, the camera wires are arranged on the cannula body in sequence. In addition, an endoscope using the endoscopic cannula is also involved. Different from the existing wiring method of binding the camera wires into a harness, the camera wires are arranged on the cannula body, so that the camera wires are dispersedly arranged on the cannula body, avoiding the camera wire harness from occupying a relatively large independent space and reducing the available space in the cannula, greatly reducing the unusable space in the cannula, facilitating the arrangement of other tubes in the endoscope cannula, effectively reducing the caliber of the cannula, improving the ease of use and endoscopy accuracy of the endoscope cannula, and reducing the discomfort and pain of the patient.

[0004] During the application process, the applicant discovered that the above application had defects during use. Although the endoscope could be inserted into the patient's body to obtain corresponding imaging data, after the endoscope cannula was inserted into the patient's body, medical staff were unable to accurately adjust the direction of the complex cannula, resulting in the endoscope being unable to accurately align with the opening of the bile and pancreas appendix, thereby reducing the doctor's intubation success rate, and both the doctor and the patient had to be exposed to radioactive light.

[0034] Embodiment 1:

[0035] See also Figure 1 - Figure 7 Shown is a visualized biliopancreatic appendix cannulation system, comprising:

[0036] A plugboard 1, wherein a finger ring 2 is fixedly connected to the end of the plugboard 1;

[0037] A mounting plate 3, the mounting plate 3 is slidably plugged into the plug plate 1, and holes 4 are respectively provided at both ends of the mounting plate 3, a knob 5 is provided on the mounting plate 3, and a power connection socket 6 is provided on the knob 5;

[0038] A steel wire 8, wherein the steel wire 8 is slidably plugged into the plug board 1, and the steel wire 8 passes through the plug board 1 and is fixedly connected to the mounting plate 3;

[0039] An installation sleeve 11, wherein the installation sleeve 11 is fixedly installed at the end of the plugboard 1, and the first branch pipe 12 and the second branch pipe 13 are fixedly connected to both sides of the installation sleeve 11;

[0040] The cannula 14 is fixedly mounted on the end of the mounting sleeve 11, and the end of the cannula 14 is fixedly connected with a terminal tube 15. The mounting sleeve 11 and the cannula 14 are three-way tubes, and the terminal tube 15 is a two-way tube. An endoscope 16 and a guide wire 17 are respectively inserted into the inside of the cannula 14 through the first branch tube 12 and the second branch tube 13, and the endoscope 16 and the guide wire 17 extend and are inserted into the two inner channels of the terminal tube 15. The steel wire 8 passes through the mounting sleeve 11 and the cannula 14 and passes out from the end of the cannula 14. One end of the steel wire 8 passes through the cannula 14 and is fixedly mounted on the outer wall of the terminal tube 15.

[0041] As can be seen from the above, when the user needs to use the intubation system to obtain imaging data of the patient's body, the cannula 14 can be inserted into the patient's body according to the conventional intubation operation. When the user needs to adjust the lens direction of the endoscope 16, the thumb can be inserted into the ring 2, and then the index finger and the middle finger can be respectively inserted into the two sockets 4. The fingertips exert force to make the plug plate 1 and the mounting plate 3 slide against each other. At this time, the sliding mounting plate 3 drives the steel wire 8 to slide inside the cannula 14. The sliding steel wire 8 pulls the end tube 15 to bend, and the bending of the end tube 15 drives the endoscope 16 to bend, thereby changing the direction of the endoscope 16. The user can bend the endoscope 16 through operation, so as to adjust the endoscope 16 to a suitable angle for inserting the guide wire.

[0042] The steel wire 8 is fixedly connected to the knob 5 , and the steel wire 8 can be electrically connected to the outside world through the power socket 6 .

[0043] To facilitate the user to insert the endoscope 16 and the guide wire 17 into the installation sleeve 11 respectively, the first branch tube 12 and the second branch tube 13 are staggered on both sides of the installation sleeve 11, and the endoscope 16 and the guide wire 17 can be inserted into the first branch tube 12 and the second branch tube 13.
