Description

Technical Field

[0001] The invention relates to the technical field of throat support and foreign body clamping, in particular to a throat esophagus support and foreign body clamping device. Background Art

[0002] Foreign objects swallowed by children may sometimes get stuck in the throat or esophagus. When removing the foreign objects, children are out of control and may not cooperate with the doctor in the foreign object removal operation. Using a laryngeal dilator to expand and support the throat can effectively improve the efficiency of foreign object removal. However, existing laryngeal dilator devices and foreign body removal tools are usually used separately, resulting in a long operation time. The general foreign body removal method is to clamp with handheld forceps, which requires high hand stability for the doctor. During the clamping process, the child's head shaking and swallowing will cause the dilator to shake with the head. The accuracy of using forceps to pass through the dilator to clamp the foreign body is reduced, and the operation is more difficult.

[0032] In one embodiment, Figure 1 As shown, the connecting member includes a connecting block 303 horizontally connected to the right end of the support plate 104, the left end of the connecting block 303 is rotationally connected to one end of the first connecting rod 301, the other end of the first connecting rod 301 is connected to the left end of the C-shaped fixed block 101, the right end of the connecting block 303 is rotationally connected to one end of the second connecting rod 302, the other end of the second connecting rod 302 is rotationally connected to the left end of the sliding block 102, when the sliding block 102 moves to the right, the sliding block 102 pulls the support plate 104 to the right through the second connecting rod 302, and under the support of the first connecting rod 301, the two support plates 104 move away from each other to achieve support for the throat.

[0033] In one embodiment, Figure 2 As shown, a camera mounting seat 106 is provided on the inner side of the left end of the support sheet 104. Generally, an endoscopic camera is used in the process of removing foreign objects, and the camera mounting seat 106 is convenient for fixing the endoscopic camera.

[0034] In one embodiment, Figure 2 and Figure 5 As shown, the clamping mechanism includes a sliding sleeve 401 slidably arranged in a fixed ring 103, a sliding core 402 is slidably arranged in the sliding sleeve 401, a chuck 403 is arranged at the right end of the sliding core 402, the chuck 403 includes two V-shaped clips connected to the right end face of the sliding core 402, the clips are arched, the chuck 403 is made of elastic stainless steel, the left end of the sliding core 402 is connected to a fixed handle 404, a rotating seat 405 is arranged on the right end face of the fixed handle 404, and the rotating seat 405 is rotatably connected to the middle part of the force application handle 406, The upper end of the force-applying handle 406 is rotatably connected to one end of the third connecting rod 407, a first clamping ring 408 is provided near the left end of the outer surface of the sliding sleeve 401, and the other end of the third connecting rod 407 is rotatably connected to the lower end of the first clamping ring 408, a return spring 409 is provided between the lower end of the force-applying handle 406 and the fixed handle 404, the sliding sleeve 401 is a bendable tube, the sliding core 402 is a bendable stainless steel core, and a bending structure is provided on the sliding sleeve 401 to bend the right end of the sliding sleeve 401. In the initial state, the return spring 409 is in a compressed state, and the force-applying handle 406 is in a bendable state. 06, the lower end is away from the fixed handle 404, the right end of the sliding sleeve 401 does not squeeze the chuck 403, under the action of the reset spring 409, the relative position between the sliding sleeve 401 and the sliding core 402 remains unchanged without external interference, the position of the sliding core 402 is adjusted by the fixed handle 404, the sliding sleeve 401 and the sliding core 402 slide or rotate synchronously in the fixed ring 103, and the position of the chuck 403 changes at the same time. After the chuck 403 approaches the foreign object, the lower end of the force-applying handle 406 is pinched, and the upper end of the force-applying handle 406 is pushed to the right through the third connecting rod 407. The sliding sleeve 401 slides to the right on the sliding core 402, and the right end of the sliding sleeve 401 squeezes the chuck 403, so that the chuck 403 closes and clamps the foreign matter. The bending structure can bend the right end of the sliding sleeve 401, and the sliding sleeve 401 drives the right end of the sliding core 402 to bend as well. The sliding sleeve 401 and the sliding core 402 rotate synchronously in the fixed ring 103, thereby expanding the clamping range of the chuck 403. The fixed ring 103 keeps the relative position between the sliding sleeve 401 and the entire device stable, thereby reducing the impact of the patient's head movement on the operator.

[0035] In one embodiment, Figure 2 , Figure 3 , Figure 6 and Fig. 9As shown, the curved structure includes a second clamping ring 501 disposed on the outer surface of the sliding sleeve 401 near the right end, two ropes 502 are symmetrically disposed at the left end of the second clamping ring 501, a rope groove 503 matching the rope 502 is disposed on the outer surface of the sliding sleeve 401, a third clamping ring 504 is disposed on the outer surface of the sliding sleeve 401 between the fixing ring 103 and the second clamping ring 501, the rope 502 slides through the third clamping ring 504, and the second clamping ring 501 and the third clamping ring 504 are embedded outside the sliding sleeve 401. The outer diameters of the second clamping ring 501 and the third clamping ring 504 are the same as the outer diameter of the sliding sleeve 401. The first clamping ring 408 is provided with a retracting structure for retracting and releasing the rope 502. The rope groove 503 is connected to the rope entrance and exit of the retracting structure. The retracting structure retracts the rope 502 on one side and releases the rope 502 on the other side at the same time, so that the part of the sliding sleeve 401 close to the right end is bent forward or backward. The third clamping ring 504 restricts the part of the rope 502 in the third clamping ring 504 to the rope groove 503, so as to limit the length of the bent part of the sliding sleeve 401.

[0036] In one embodiment, Figure 3 , Figure 4 and Figure 6 As shown, the retractable structure includes a fixed sleeve 601 connected to the upper end of the first clamping ring 408, a matching rotating sleeve 602 is rotatably provided on the outer side of the fixed sleeve 601, the rope 502 is wound around the outer surface of the rotating sleeve 602 and the end is fixed on the outer surface of the rotating sleeve 602, the winding directions of the two ropes 502 are opposite, a rotating block 603 is rotatably provided on the inner side of the fixed sleeve 601, the upper end surface of the rotating block 603 is connected to the rotating disk connecting column 604, the upper end of the rotating disk connecting column 604 is connected to the third rotating disk 605, the outer diameter of the third rotating disk 605 is larger than the outer diameter of the rotating sleeve 602, the upper surface of the rotating sleeve 602 is annularly distributed with a plurality of plug-in grooves 606, A plurality of plug-in posts 607 are provided at positions corresponding to the plug-in slots 606 on the lower end surface of the disk 605, and the plug-in slots 606 match the plug-in posts 607. A rotation limiting structure is provided between the rotating block 603 and the fixed sleeve 601. By twisting the third rotating disk 605, the plug-in posts 607 on the third rotating disk 605 are plugged into the plug-in slots 606 to drive the rotating sleeve 602 to rotate, thereby retracting the rope 502 on one side and releasing the rope 502 on the other side at the same time, thereby bending the right end of the sliding sleeve 401. After the third rotating disk 605 is released, the rotation limiting structure prevents the tension on the rope 502 from pulling the third rotating disk 605, thereby maintaining the bending degree of the right end of the sliding sleeve 401 after the third rotating disk 605 is released.

[0037] In one embodiment, Figure 7As shown, the rotation limiting structure includes a plurality of telescopic cavities 701 arranged on the rotating block 603, the opening of the telescopic cavity 701 is arranged on the upper surface of the rotating block 603, the telescopic cavity 701 is connected to the side of the rotating block 603, a telescopic block 702 is slidably arranged in the telescopic cavity 701, the head of the telescopic block 702 is exposed to the outside of the side of the rotating block 603, a force spring 703 is arranged in the telescopic cavity 701, one end of the force spring 703 is connected to the tail of the telescopic block 702, and the other end of the force spring 703 contacts the inner wall of the telescopic cavity 701, and the rotating block 603 is provided with a telescopic block 702. A sealing cover 704 is provided on the surface for sealing the telescopic cavity 701, and a vertical limiting strip 705 matching the head of the telescopic block 702 is provided on the inner wall of the fixed sleeve 601. Under the action of the force spring 703, the head of the telescopic block 702 is stuck in the gap of the limiting strip 705, so that after the curvature of the right end of the sliding sleeve 401 is adjusted and the third rotating disk 605 is released, there is no relative rotation between the rotating block 603 and the fixed sleeve 601, so that the curvature of the right end of the sliding sleeve 401 is maintained, and the friction between the telescopic block 702 and the limiting strip 705 ensures that the rotating block 603 will not fall out of the fixed sleeve 601 during use.

[0038] In one embodiment, Figure 1 As shown, a cantilever connecting column 105 is provided on the right side of the front end surface of the C-shaped fixing block 101, so as to facilitate the installation of the entire device on the cantilever. The cantilever bears part of the weight of the entire device, thus reducing the burden on the patient.

[0039] The above embodiment discloses a throat esophagus support and foreign body clamping device, wherein the first rotating disk 204 rotates the screw rod 201, and the moving block 202 moves on the screw rod 201, and the moving block 202 drives the sliding block 102 to slide on the C-shaped fixed block 101 through the stud 203. When the sliding block 102 slides to the left, under the action of the connecting member, the sliding block 102 pushes the supporting piece 104 to the left through the second connecting rod 302. Under the support of the first connecting rod 301, the two supporting pieces 104 approach each other. After the supporting piece 104 is inserted into the throat, the sliding block 102 is moved rightward, and the sliding block 102 is moved to the left. 02 The support sheet 104 is pulled to the right by the second connecting rod 302. Under the support of the first connecting rod 301, the two support sheets 104 move away from each other to support the throat. Since the sliding sleeve 401 can slide and rotate in the fixing ring 103, when the patient's head shakes or swallows, causing the support sheet 104 to shake, the relative position between the sliding sleeve 401 and the C-shaped fixing block 101 remains stable, avoiding a large shake of the clamp 403 to affect the accuracy of clamping foreign objects. The position of the sliding core 402 is adjusted by the fixing handle 404, and the sliding sleeve 401 and the sliding The core 402 synchronously slides or rotates in the fixed ring 103, and the position of the chuck 403 changes. For foreign bodies attached to the esophageal wall, the third rotating disk 605 is twisted, and the plug-in column 607 on the third rotating disk 605 is plugged into the plug-in groove 606 to drive the rotating sleeve 602 to rotate, so that the rope 502 on one side is taken in and the rope 502 on the other side is released at the same time, so that the right end of the sliding sleeve 401 is bent, and the sliding sleeve 401 drives the right end of the sliding core 402 to bend, and the sliding sleeve 401 and the sliding core 402 can rotate synchronously in the fixed ring 103, and the chuck The clamping range of 403 is expanded. After the chuck 403 approaches the foreign object, the lower end of the force handle 406 is pinched, and the upper end of the force handle 406 pushes the sliding sleeve 401 to the right through the third connecting rod 407, so that the sliding sleeve 401 slides to the right on the sliding core 402, and the right end of the sliding sleeve 401 squeezes the chuck 403, so that the chuck 403 closes and clamps the foreign object, and then the sliding core 402 is pulled by the fixed handle 404 to transfer the foreign object to the inside of the support plate 104, and the sliding block 102 is moved to the left to cancel the support for the throat and remove the support plate 104 from the throat, completing the operation of removing the foreign object from the throat.

[0040] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
