Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] Example 1

[0046] See also Figure 1 - Figure 7 , a gastrointestinal catheterization assistive scope that facilitates the placement of intestinal obstruction catheters through visualization, including:

[0047] Intestinal obstruction catheter fixation device 1;

[0048] A pagoda-shaped disposable Y-type connecting valve 2 installed on the top of the intestinal obstruction catheter fixing piece 1;

[0049] A catheter 3 installed at the bottom of the intestinal obstruction catheter fixing member 1;

[0050] The electronic flexible mirror 4 with a channel is plugged into the inner side of the pagoda-shaped disposable Y-shaped connecting valve 2, and the bottom of the electronic flexible mirror 4 with a channel passes through the intestinal obstruction catheter fixing piece 1 and extends to the inner side of the catheter 3;

[0051] A control handle 12 mounted on the top of the electronic soft mirror with channel 4;

[0052] An adjustment mechanism 13 provided on the control handle 12;

[0053] A plurality of working channels 5 are provided on the channeled electronic soft endoscope 4, and the plurality of working channels 5 are arranged in a circular array;

[0054] A plurality of guide wires 6 are sequentially arranged in a circular array in the channeled electronic soft endoscope 4, and the plurality of guide wires 6 are respectively plugged into the plurality of working channels 5, and the plurality of guide wires 6 are all connected to the adjustment mechanism 13;

[0055] A fixing assembly 7 is provided at the bottom of the guide wire 6;

[0056] And a protective component 16 is provided on the electronic soft mirror with a channel 4.

[0057] The present invention provides a gastrointestinal catheterization auxiliary mirror that is easy to insert into the intestinal obstruction catheter through visualization. When in use, the electronic soft mirror with a channel 4 is inserted into the catheter 3 through the pagoda-shaped disposable Y-shaped connecting valve 2 and the intestinal obstruction catheter fixing piece 1, and then inserted into the intestinal obstruction catheter channel, so that image navigation can be realized, helping the operator to intuitively observe the direction of the intestine, so as to more accurately insert the catheter 3 into the intestinal obstruction site. At the same time, with the cooperation of the working channel 5 and the guide wire 6, the device has both support and guidance functions, reducing the impact of the intestinal bend on the electronic soft mirror with a channel 4 The medical staff then controls the multiple guide wires 6 through the adjustment mechanism 13, so that the guide wires 6 can drive the flexible end of the channeled electronic flexible mirror 4 to bend under the cooperation of the fixing component 7. At the same time, the channeled electronic flexible mirror 4 drives the catheter 3, thereby realizing multi-directional bending of the catheter 3 and the channeled electronic flexible mirror 4 to adapt to the sharp angle turning of the intestine. Finally, the protective component 16 can protect the camera on the channeled electronic flexible mirror 4 to avoid the camera on the channeled electronic flexible mirror 4 from being stained with stains, which makes the shooting picture blurred and unclear.

[0058] Furthermore, two LED lights 8 are symmetrically fixedly installed on the bottom of the electronic soft mirror with channel 4, and the two LED lights 8 are respectively located on both sides of the camera on the electronic soft mirror with channel 4.

[0059] Specifically, the LED light 8 can illuminate the area around the flexible end of the electronic flexible endoscope with channel 4, so that the camera at the flexible end of the endoscope can take clearer pictures.

[0060] Furthermore, the fixing assembly 7 includes an outer spiral tube 71 fixedly mounted on the bottom end of the guide wire 6 , and an inner threaded sleeve 72 is threadedly connected to the outer side wall of the outer spiral tube 71 .

[0061] Specifically, the inner screw sleeve 72 is manually threaded onto the outer screw tube 71, so that while the guide wire 6 is manually controlled, the guide wire 6 drives the inner screw sleeve 72 through the outer screw tube 71, so that the top of the inner screw sleeve 72 contacts the end of the soft mirror with a channel electronic soft mirror 4, and then can drive the end of the soft mirror with a channel electronic soft mirror 4 to bend, thereby realizing multi-directional bending of the catheter 3 and the electronic soft mirror with a channel 4, and adapting to the sharp angle turns of the intestine.

[0062] Furthermore, a protective sleeve 9 is installed on the outer side walls of the outer spiral tube 71 and the inner screw sleeve 72, and the material of the protective sleeve 9 is rubber, and the groove on the inner side of the protective sleeve 9 is an inverted T shape.

Since the groove on the inner side of the protective sleeve 9 is an inverted T-shape, the protective sleeve 9 can protect the outer side walls of the outer screw tube 71 and the inner screw sleeve 72 while also protecting the exposed top, thereby improving the protection area and effect of the protective sleeve 9.

[0064] Furthermore, the adjustment mechanism 13 includes a first T-shaped rod 1301 rotatably mounted on the front side of the control handle 12, and the two guide wires 6 located on the left and right sides are fixedly connected to the first T-shaped rod 1301.

[0065] Specifically, by manually rotating the first T-shaped rod 1301 forward or reverse, the first T-shaped rod 1301 can drive the guide wire 6 located on the left or right side to reel, thereby enabling the soft end of the electronic soft endoscope with a channel 4 to bend left or right. Then, when the soft end of the electronic soft endoscope with a channel 4 needs to bend forward or backward, the second T-shaped rod 1302 is manually rotated forward or reversed, thereby enabling the second T-shaped rod 1302 to drive the guide wire 6 located on the front or rear side to reel, thereby enabling the soft end of the electronic soft endoscope with a channel 4 to be adjusted at multiple angles.

[0066] Furthermore, an instrument channel 14 and a video signal line 15 are respectively provided on the control handle 12 .

[0067] Specifically, water can be injected or surgical instruments can be inserted through the instrument channel 14 to perform related operations. Then, the other end of the video signal line 15 can be manually connected to the electronic endoscope image processor, so that the video signal from the electronic endoscope with channel 4 can be transmitted back to the electronic endoscope image processor for processing.

[0068] Furthermore, the protective component 16 includes a fixed tube 1601 rotatably mounted on the outer wall of the channeled electronic soft mirror 4, and the fixed tube 1601 is located near the end of the channeled electronic soft mirror 4, the inner side of the fixed tube 1601 is threadedly connected to a connecting tube 1602, and a lens 1603 is fixedly mounted on the inner wall of the connecting tube 1602, a driving mechanism is provided on the inner side of the channeled electronic soft mirror 4, and the driving mechanism is connected to the fixed tube 1601.

[0069] Specifically, the fixed tube 1601 is driven to rotate by the driving mechanism, and then the rotating fixed tube 1601 synchronously drives the connecting tube 1602 and the lens 1603 inside it, so that the stains on the surface of the lens 1603 can be removed under the action of centrifugal force, thereby ensuring the clarity of the picture taken by the channel electronic soft mirror 4.

[0070] Furthermore, the driving mechanism includes a motor 17 fixedly mounted on the channeled electronic soft mirror 4, the output end of the motor 17 is fixedly connected to an inner magnet ring 18, an outer magnet ring 19 is fixedly mounted on the inner wall of the fixed tube 1601, and the inner magnet ring 18 and the outer magnet ring 19 are non-contact magnetically coupled.

[0071] Specifically, the inner magnet ring 18 is driven by the motor 17 , and then the fixed tube 1601 is rotated by the outer magnet ring 19 , so that the stains on the surface of the lens 1603 can be removed under the action of centrifugal force.

[0072] Example 2

[0073] Based on Example 1, in this embodiment: a lubricating layer is provided on the outer walls of the catheter 3 and the electronic flexible mirror with a channel 4. The lubricating layer is a hydrophilic coating 10 coated on the outer walls of the catheter 3 and the electronic flexible mirror with a channel 4. The outer wall of the hydrophilic coating 10 is coated with a medical glycerin layer 11.

[0074] The technical solution provided in this embodiment is: through the hydrophilic coating 10 and the medical glycerin layer 11, the friction resistance between the catheter 3 and the intestinal wall and between the channeled electronic flexible endoscope 4 and the catheter 3 can be effectively reduced, which can effectively improve the smoothness and safety of insertion.

[0075] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
