[0030] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0031] See also Figure 1-6 As shown, a digestive tract bleeding suction device, the digestive tract bleeding suction device comprising:

[0032] A suction assembly 2 is fixedly arranged on the side of the gastroscope 1, and the suction assembly 2 and the gastroscope 1 are fixed via a fixing portion 5;

[0033] The outer surfaces of the gastroscope 1 and the suction assembly 2 are covered and fixed with a coating layer 3;

[0034] The interior of the suction component 2 is provided with a stirring component 4, and the stirring component 4 is used to stir and break the blood clot during suction;

[0035] Through the above technical solution, the suction component 2 is combined and fixed with the gastroscope 1, and an external coating layer 3 is provided, so that the suction head end of the suction component 2 can be fixed to the front end of the gastroscope, so that the accumulated blood in the gastric cavity can be effectively sucked out, and a stirring component 4 is provided. Through the setting of the stirring component 4, larger blood clots can be stirred and broken, thereby ensuring effective suction when blood clots are formed due to heavy bleeding.

[0036] The suction assembly 2 comprises a suction tube 201 and a suction port at the front end. The suction port is located at the front end of the gastroscope 1 and has a diameter of 6 mm or greater. A connecting chamber 202 is fixedly connected to the upper end of the suction tube 201. A connecting tube 203 is fixedly connected to the side wall of the connecting chamber 202. One end of the connecting tube 203 is provided with a connector 204. With this technical solution, when blood clots need to be aspirated, the connector 204 can be connected to a medical negative pressure suction device, thereby allowing the blood clot to be aspirated through the suction port at the front end of the suction tube 201.

[0037] Embodiment 1 of the fixing portion 5:

[0038] The fixing portion 5 is a buckle, which is fixed to the curved outer wall of the suction tube 201 . The buckle is engaged with the curved wall of the gastroscope 1 , thereby fixing the gastroscope 1 and the suction tube 201 .

[0039] Embodiment 2 of the fixing portion 5:

[0040] The fixing portion 5 is a hook and loop fastener, one end of which is fixed to the suction tube 201 . The hook and loop fastener surrounds the gastroscope 1 and is fixed to the gastroscope 1 , thereby fixing the gastroscope 1 to the suction tube 201 .

[0041] The coating layer 3 is a medical-grade PE plastic film. Through the setting of the coating layer 3, it can be replaced each time it is used to prevent cross infection. Specifically, the plastic film is a film with an adhesive layer. When replacing, the old film is torn off and the new film is wrapped around the gastroscope 1 and the suction component 2, and sealed and fixed by the adhesive layer.

[0042] The stirring assembly 4 includes a fixed end cover 401, a rotating shaft 402, a transmission shaft 403, a retaining frame 404 and a working part 405. The transmission shaft 403 is arranged in the inner cavity of the suction tube 201, and the bottom end of the transmission shaft 403 is fixedly connected to the working part 405. The working part 405 is arranged on the retaining frame 404 and is rotatably connected to the retaining frame 404. The retaining frame 404 is fixedly connected to the inner wall of the suction tube 201, and the upper end of the transmission shaft 403 is fixedly connected to the rotating shaft 402. Through the present technical solution, by connecting the rotating shaft 402 to an external driving device, the driving device drives the rotating shaft 402 to rotate, and then drives the transmission shaft 403 to rotate, thereby driving the working part 405 to rotate, and the blood clot is stirred and broken.

[0043] The rotating shaft 402 is rotatably connected to a fixed end cover 401, and the fixed end cover 401 is fixedly arranged at one end of the connecting compartment 202.

[0044] The transmission shaft 403 is a slender, flexible shaft capable of transmitting torque. Preferably, the transmission shaft 403 is a coil spring structure wound with nickel-titanium alloy wire, with an outer diameter of 1.2 mm and a bending radius of ≤ 20 mm. During torque transmission, the gastroscope 1 is allowed to bend 180° without affecting the transmission of rotational motion. The outer layer of the transmission shaft 403 is coated with polytetrafluoroethylene to reduce frictional resistance with the inner wall of the suction tube 201.

[0045] The working part 405 includes a circular plate 4051 and a stirring blade 4053. The circular plate 4051 is fixedly set at the bottom end of the transmission shaft 403. A plurality of connectors 4052 are fixedly set on the bottom side of the circular plate 4051. The connectors 4052 are distributed in a circular array. The bottom end of the connector 4052 is rotatably connected to the stirring blade 4053. A fixed guide rod 4054 is fixedly connected to the center position of the circular plate 4051, and a movable guide rod 4055 is slidably connected in the inner cavity of the fixed guide rod 4054. The bottom end of the movable guide rod 4055 is rotatably connected to a number of connecting frames 4056. One end of the connecting frame 4056 extends to the side wall of the stirring blade 4053 and is rotatably connected to the stirring blade 4053. The bottom end of the movable guide rod 4055 is fixedly connected to one end of a spring 4057, and the other end of the spring 4057 is fixedly connected to the bottom surface of the circular plate 4051. Through this technical solution, when the transmission shaft 403 rotates, the circular plate 4051 can be driven to rotate. The centrifugal force generated causes the movable guide rod 4055 to overcome the resistance of the spring 4057 and move downward, and push the stirring blade 4053 outward through the connecting frame 4056, so that the working diameter is expanded, thereby performing large-scale stirring and crushing.

[0046] Specifically, when the transmission shaft 403 rotates, the circular plate 4051 drives the connecting head 4052 and the stirring blade 4053 to perform circular motion. The centrifugal force generated by the stirring blade 4053 forces the movable guide rod 4055 to slide axially downward along the fixed guide rod 4054. At this time, the spring 4057 is stretched; when the movable guide rod 4055 moves downward, the connecting frame 4056 pushes the stirring blade 4053 to expand outward around the hinge point of the connecting head 4052, so that the maximum working diameter of the stirring blade 4053 is expanded. When the speed decreases, the rebound force of the spring 4057 drives the movable guide rod 4055 to move upward, driving the stirring blade 4053 to retract inward to its initial state.

[0047] During operation, first start the stirring component 4 to rotate, and then the working part 405 is expanded to mechanically break up the blood clot; simultaneously turn on the external negative pressure device to generate negative pressure at the suction port, and the broken blood clot fragments are sucked into the connecting chamber 202 through the suction tube 201; the synergistic effect time of the stirring component 4 and the negative pressure suction is controlled at 3-5 minutes / time to avoid mucosal damage.

[0048] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
