Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical treatment, in particular to a visible pharyngeal foreign body forceps. Background Technique
[0002] A foreign body forceps is a medical device specifically designed for removing and clearing foreign bodies in the human pharynx. The foreign body forceps mainly consists of a forceps head, an outer tube, a cable, a handle, etc. At present, when using the foreign body forceps, a flashlight is needed for illumination. If the foreign body is in a relatively deep position in the pharynx, a rigid nasopharyngoscope is generally needed to confirm the position of the foreign body. In this way, during the operation, it is necessary to hold the rigid nasopharyngoscope and the foreign body forceps separately for operation, and it is not convenient to operate with both hands at the same time. At the same time, because the positions where the foreign body is stuck in the throat are different, during actual operation, it is often necessary to adjust the posture of holding the forceps to make the opening of the forceps correspond to the angle of the foreign body. The change of the holding forceps posture makes the operation less convenient than holding it directly. At the same time, because the rigid nasopharyngoscope is relatively large in size and the pharyngeal space is small, the rigid nasopharyngoscope pushing against the pharynx easily causes nausea, which further affects the operation.

[0011] (III) Advantageous Effects
[0012] Compared with the prior art, the present utility model provides a visible pharyngeal foreign body forceps, which has the following advantageous effects:
[0013] 1. For this foreign body forceps, by installing a camera and a lighting lamp on the pliers rod with a sleeve, supplementary lighting can be provided by means of the lighting lamp during use, and at the same time, imaging of the inside of the pharynx is carried out by using the camera, which is convenient for positioning and confirmation of the foreign body. The rotatable setting of the pliers head enables it to rotate to the corresponding orientation according to the position of the foreign body, so as to facilitate the clamping of the foreign body, thus facilitating the removal operation of the foreign body. At the same time, the integrated setting of the lighting and the forceps not only does not require separate operation, but also reduces the space and reduces the reaction of causing nausea in the pharynx.
[0014] 2. For this foreign body forceps, through the restraint of the guiding shaft and the sleeve rod, the soft rope can ensure the connection to the movable clamping plate while preventing the looseness from being damaged due to rotation when the pliers head rotates, ensuring a stable movement stroke of the pliers handle to the movable clamping plate.
[0015] 3. For this foreign body forceps, through the combination of the push plate and the sleeve with flat cuts, when the pliers head rotates, a positioning effect in four directions can be provided after rotation. After positioning, the pliers head is not easily rotated randomly, which is convenient for operation and use. Description of the Drawings

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.
[0022] Please refer to Figures 1-4 , a visible pharyngeal foreign body forceps, including a hollow pliers rod 1, a rotatable pliers head 2 is installed at the front end of the pliers rod 1, a fixed clamping plate 3 is integrally formed and connected to the front end of the pliers head 2, a movable clamping plate 4 is closely attached to the side of the fixed clamping plate 3, the movable clamping plate 4 is hinged and fixed to the corresponding position of the pliers head 2 through a hinge shaft 5, a closing spring 6 is installed at the position corresponding to the end of the movable clamping plate 4 inside the pliers head 2, and the closing spring 6 pushes the movable clamping plate 4 to closely attach to the fixed clamping plate 3 to form a closure. A hollow sleeve rod 9 is hot-melt installed at the center position of the rear side of the pliers head 2. Two fixed plates 8 are hot-melt installed inside the pliers head 2 between the front end of the sleeve rod 9 and the rear end of the movable clamping plate 4. Two guide shafts 7 are hot-melt installed between the two fixed plates 8. A limit sleeve 14 is hot-melt installed outside the sleeve rod 9 at the rear side of the pliers head 2. A limit ring groove 15 is preset on the outer peripheral surface of the limit sleeve 14. A limit ring plate 16 is hot-melt installed on the inner wall of the front end of the pliers rod 1 corresponding to the limit ring groove 15. The limit ring plate 16 abuts against the limit ring groove 15 to form a limit rotational connection between the pliers head 2 and the pliers rod 1. A fixed pliers handle 18 is integrally formed and installed at the position close to the front side of the rear end of the pliers rod 1. A movable pliers handle 19 is hinged and installed at the position close to the rear side of the rear end of the pliers rod 1. A soft rope 17 is connected between the rear end of the movable clamping plate 4 and the movable pliers handle 19. The soft rope 17 bypasses the guide shaft 7 and passes through the sleeve rod 9 into the pliers rod 1;
[0023] A sleeve 20 is welded and installed on the outer side of the pliers rod 1 corresponding to the front end and the middle position. The front end of the sleeve 20 is close to the pliers head 2. An LED illuminating lamp 22 and a camera 23 are installed inside the front end of the sleeve 20. The signal wires 21 of the illuminating lamp 22 and the camera 23 pass through the rear end of the sleeve 20 and are connected to the back position of the display 24. A power supply wire 25 is also connected to the back of the display 24. A grip 26 is hot-melt installed at the bottom of the display 24.
[0024] When in use, first connect the power supply through the power supply wire 25 to supply power, so that the lighting lamp 22 and the camera 23 are turned on and working. The lighting lamp 22 emits light when it works. Hold the pliers rod 1 from the position of the pliers handle, and use the camera 23 to display the image in front on the display 24. Insert the pliers head 2 into the throat. On the basis of the light provided by the lighting lamp 22, confirm the position of the foreign body stuck in the pharynx through the camera 23. After confirming the position of the foreign body, open the movable pliers handle 19, pull the movable splint 4 with the soft rope 17, so that it compresses and deforms the closing spring 6 and then opens. Move to make the foreign body enter between the fixed splint 3 and the movable splint 4, close the movable pliers handle 19, and the closing spring 6 resets to push the movable splint 4 to close, thereby biting the foreign body. At this time, the foreign body can be taken out. When it is found that the position where the foreign body is stuck is not in the same direction as the opening direction of the movable splint 4 and the pliers holding posture needs to be adjusted to adapt to the position of the foreign body, temporarily take out the pliers, and use the limiting rotation relationship between the limiting sleeve 14 and the limiting ring plate 16 to rotate the entire pliers head 2 so that it is adjusted to the required angle, and then insert it again to take out the foreign body. You don't need to change the pliers holding posture.
