[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0028] A specific embodiment of the utility model is as follows Figure 1 and Figure 2 As shown, a foreign body removal device for digestive endoscope (hereinafter referred to as removal device) is disclosed, comprising a connecting tube 1, a capturing sleeve 2, an air bag 3 and an airway tube 4, one end of the capturing sleeve 2 is fixedly connected to the connecting tube 1, the other end of the capturing sleeve 2 is connected to the air bag 3, and the airway tube 4 is connected to the air bag 3. The connecting tube 1 is used to connect with the digestive endoscope, the capturing sleeve 2 is used to capture foreign bodies in the digestive tract, and the air bag 3 can be inflated through the airway tube 4, thereby expanding and blocking the capturing sleeve 2, preventing the foreign bodies in the capturing sleeve 2 from escaping from the capturing sleeve 2, and there is no need to re-perform the capturing operation, thereby improving work efficiency.

[0029] Preferably, the retrieval device of the utility model further comprises a first restraining ring 5 and a first traction rope 6. The first restraining ring 5 is arranged at one end of the capture sleeve 2, which is an open end. The airbag 3 is connected to the capture sleeve 2 through the first restraining ring 5; one end of the first traction rope 6 is connected to the first restraining ring 5, and the other end of the first traction rope 6 is a free end. The first traction rope 6 is arranged in the connecting tube 1 and the capture sleeve 2. The outer wall of the capture sleeve 2 can be connected to the outer wall of the connecting tube 1, and the capture sleeve 2 is in a reflexed state. At this time, the capture sleeve 2 is used to capture foreign matter in the esophagus; the outer wall of the capture sleeve 2 can be separated from the outer wall of the connecting tube 1, and the capture sleeve 2 is in a wrapped state. At this time, the foreign matter is stored in the capture sleeve 2. The first traction rope 6 is used to pull the capture sleeve 2, so that the capture sleeve 2 is transformed from the reflexed state to the wrapped state, and the foreign matter is wrapped.

[0030] Preferably, the connecting tube 1 and the capturing sleeve 2 are both in the shape of round tubes, so as to adapt to the shape of the esophagus and reduce damage to the inner wall of the esophagus.

[0031] Preferably, the airbag 3 is a circular airbag to adapt to the inner wall of the capture sleeve 2.

[0032] Preferably, there are multiple first traction ropes 6, and the connection points between each first traction rope 6 and the first restraint ring 5 are evenly distributed on the circumference of the first restraint ring 5, so that when the multiple first traction ropes 6 transform the capture sleeve 2 from the folded state to the wrapped state, the force on the first restraint ring 5 is uniform.

[0033] Preferably, the first constraint ring 5 is an elastic constraint ring, and the first constraint ring 5 is used to constrain the open end of the capture sleeve 2 so that the inner diameter of the open end of the capture sleeve 2 remains unchanged.

[0034] If the capture sleeve 2 is transformed from the folded state to the wrapped state in the esophagus, but the foreign body is not wrapped, the digestive endoscope needs to be removed from the esophagus and the capture sleeve 2 needs to be manually placed in the folded state, which affects the surgical operation. Figure 3 As shown, the removal device of the utility model also includes a second traction rope 7, one end of the second traction rope 7 is connected to one end of the capture sleeve 2, and the other end of the second traction rope 7 is a free end. The second traction rope 7 is used to connect the outer wall of the capture sleeve 2 with the outer wall of the connecting tube 1, so that the capture sleeve 2 is in a folded state, and there is no need to remove the digestive endoscope from the esophagus and manually fold the capture sleeve 2, thereby ensuring the smooth progress of the foreign body removal operation.

[0035] Preferably, there are multiple second traction ropes 7, and the connection points between each second traction rope 7 and the capture sleeve 2 are evenly distributed on the circumference of the capture sleeve 2, so that when the multiple second traction ropes 7 transform the capture sleeve 2 from the wrapped state to the folded state, the capture sleeve 2 is evenly stressed.

[0036] In order to facilitate the capture sleeve 2 to be in the folded state, preferably, as Figure 2 As shown, the capture sleeve 2 includes a plurality of structural plates 21, and the outer wall of the capture sleeve 2 is composed of a plurality of structural plates 21. One end of the structural plate 21 is connected to the first restraining ring 5, and the other end of the structural plate 21 is connected to the connecting pipe 1. The first restraining ring 5 is used to restrain the plurality of structural plates 21, so that there is no gap between the plurality of structural plates 21 and the connecting end of the first restraining ring 5.

[0037] When the capture sleeve 2 is wrapped, gaps may exist between the multiple structural plates 21, causing foreign matter to break away from the outer wall of the capture sleeve 2 and cause damage to the esophagus. Figure 3 As shown, the retrieval device of the present invention further includes a second restraining ring 8 , which is disposed on the capture sleeve 2 . Specifically, the second restraining ring 8 is disposed on the side wall of the structural plate 21 .

[0038] Preferably, the second restraint ring 8 is an elastic restraint ring, which is used to restrain the multiple structural plates 21 to prevent gaps from appearing on the outer wall of the capture sleeve 2, thereby preventing foreign matter from detaching from the outer wall of the capture sleeve 2 and causing damage to the esophagus.

[0039] The implementation principle of a foreign body removal device for a digestive endoscope in this embodiment is as follows: when it is needed to be used, the operator connects the connecting tube 1 to the digestive endoscope, and connects the airway tube 4 to the inflation device. The operator folds the capture sleeve 2 by pulling the free end of the second traction rope 7. The first constraint ring 5 can keep the capture sleeve 2 folded back and sleeved on the outer wall of the connecting tube 1. At this time, the digestive endoscope is pushed into the patient's body. After the foreign body is captured by the instrument, the operator pulls the free end of the first traction rope 6 to separate the folded capture sleeve 2 from the connecting tube 1 and wrap the foreign body. At this time, external gas can be transported to the airbag 3 through the airway tube 4 to expand the airbag 3. As the airbag 3 expands, the first constraint ring 5 can be blocked, so that the foreign body cannot escape from the capture sleeve 2.

[0040] Compared with the prior art, the airbag 3 of the removal device of the utility model can be inflated through the airway tube 4, thereby expanding and blocking the capture sleeve 2, preventing the foreign matter in the capture sleeve 2 from escaping from the capture sleeve 2, and will not cause secondary injury to the patient, thereby improving work efficiency; the second traction rope 7 can connect the outer wall of the capture sleeve 2 with the outer wall of the connecting tube 1, so that the capture sleeve 2 is in a folded state, and there is no need to remove the digestive endoscope from the esophagus and manually fold the capture sleeve 2, thereby ensuring the smooth progress of the foreign body removal operation; the outer wall of the capture sleeve 2 is composed of a plurality of structural plates 21, which is convenient for putting the capture sleeve 2 in a folded state; the second restraint ring 8 can restrain a plurality of structural plates 21, prevent gaps from appearing on the outer wall of the capture sleeve 2, thereby preventing foreign matter from escaping from the outer wall of the capture sleeve 2 and causing damage to the esophagus, thereby ensuring the smooth progress of the foreign body removal operation.

[0041] The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
