Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a double-chuck esophageal foreign body forceps. Background Art

[0002] In clinical surgery using esophageal foreign body forceps, sometimes some tricky situations may be encountered. For a clearer description, in the esophageal tube: the part close to the tongue is called the upper end, and the part close to the stomach is called the lower end. Some flaky foreign bodies, such as flaky fish bones, may cause the upper end to be stuck in the esophageal wall when causing esophageal obstruction, and the lower end to tilt and form an angle with the esophageal wall. Since the existing esophageal foreign body forceps can only clamp the foreign body from the upper end of the foreign body, even if the situation in the esophagus can be seen clearly, it is not easy to handle such foreign bodies. For example, the patent with patent number CN115414102A discloses a visualized esophageal foreign body forceps, including a first clamp handle and a second clamp handle, the first clamp handle and the second clamp handle are hinged at the upper part, the top of the second clamp handle is provided with a pull block, the upper part of the first clamp handle is hollow and an extension catheter is provided at the end away from the second clamp handle, and the extension catheter is provided with a clamp head at the end away from the first clamp handle. Although this structure can see the situation inside the esophagus through the camera and can judge the situation of foreign matter more accurately, there is not much optimization in the operation of the chuck, and it is still difficult to handle such situations.

[0005] Wherein, the secondary long tube is provided with a slide plate along the length direction, and the main long tube is provided with a slide groove outside, and the slide plate is placed in the slide groove.

[0006] Wherein, the auxiliary clamp is arranged in reverse.

[0007] Wherein, the connecting rod side walls of the auxiliary clamp have opening and closing slide grooves on both sides, and the auxiliary long tube has a sliding column slidably arranged in the opening and closing slide grooves, which is used to link the rotation of the auxiliary clamp along its lower side and the tail of the main long tube.

[0008] Wherein, the tail portion of the main long tube is provided with a plane (14) that engages with the auxiliary clamp engagement surface (71).

[0009] Wherein, the secondary long tube is provided with a hollow groove for cooperating with the secondary clamp to bite onto the plane.

[0010] The lower end of the auxiliary clamp has a rotating round head, the rotating round head is provided with an auxiliary clamp round hole (72) for hinged connection with the main long tube, and the peripheral surface of the rotating round head is provided with an angle limiting protrusion for limiting the maximum opening angle of the auxiliary clamp.

[0011] The implementation of the embodiments of the utility model has the following beneficial effects: the utility model adds an auxiliary chuck in the opposite direction on the basis of the original chuck, so that the instrument can use two chucks to clamp foreign objects from two opposite directions respectively, and is used to deal with sheet-like foreign objects that cannot be clamped from above because of the downward angle with the esophageal wall; and a restriction ring can be used to limit the movement of the auxiliary long tube, so that the auxiliary chuck is always in a closed state, reducing its influence on the use of the main chuck.
