[0047] like Figures 1 to 10As shown, an embodiment of the present invention provides a clamping forceps for removing foreign bodies from the throat, including a first handle 1 and a second handle 2, one end of the first handle 1 is fixedly connected to the second bend 4, one end of the second handle 2 is fixedly connected to the first bend 3, one end of the second bend 4 is fixedly connected to an external threaded ring 7, the outer surface of the external threaded ring 7 is connected to a rotating clamping component 5, and one side of the first handle 1 and the second handle 2 are both connected to a fixing component 6.

[0048] like Figures 2 to 6 As shown, the rotating clamping assembly 5 includes a first internally threaded sleeve 53 threadedly connected to the surface of the externally threaded ring 7 and a rectangular frame 52 hinged at one end of the first bend 3, a swing arm 51 is fixedly connected to one side of the rectangular frame 52, a fixed shaft 511 is fixedly connected to the upper surface of the swing arm 51, a diamond wire 516 is wound around the outer surface of the fixed shaft 511, a first clamping block 54 is rotatably connected to one side of the first internally threaded sleeve 53, a support shaft 510 is fixedly connected to one side of the first clamping block 54, a gear 58 is fixedly connected to the middle of the outer surface of the support shaft 510, and second clamping blocks 55 are fixedly connected to both sides of the support shaft 510, a semicircular through groove 512 is provided on one side of the first internally threaded sleeve 53, a moving plate 513 is slidably connected to the inner side wall of the first internally threaded sleeve 53, a semicircular groove 515 is provided on one side of the moving plate 513, a telescopic rod 514 is slidably connected to the interior of the semicircular groove 515, and a rack 59 is fixedly connected to one side of the telescopic rod 514.

[0049] A third spring 517 is fixedly connected to the edge of one side of the movable plate 513, one side of the telescopic rod 514 passes through the interior of the semicircular through groove 512 and slides, one side of the rack 59 extends to the bottom of the gear 58 and meshes with the gear 58, a hinge shaft is provided at the hinge between the rectangular frame 52 and the first bend 3, and the hinge shaft is located inside the rectangular frame 52 and adapts to each other, the swing arm 51 and the second bend 4 are hinged to each other, and the first handle 1 and the second handle 2 are hinged to each other in the middle.

[0050] A replacement assembly 56 is connected to one side of the movable plate 513 away from the telescopic rod 514 , a guide assembly 57 is connected to one side of the inner wall of the first internally threaded sleeve 53 , and the other end of the diamond wire 516 passes through the guide assembly 57 and is connected to the replacement assembly 56 .

[0051] Through the above technical solution, when the clamping forceps are used, the first handle 1 and the second handle 2 are opened to drive the first bend 3 and the second bend 4 to rotate and cross each other, one end of the first bend 3 drives one end of the swing arm 51 to rotate around the hinge, and the swing arm 51 drives the fixed shaft 511 to swing to one side, and the fixed shaft 511 pulls the diamond wire 516 to drive the replacement component 56 and the moving plate 513 to move to one side inside the first internally threaded sleeve 53, stretching the third spring 517, and the first internally threaded sleeve 53 pulls the rack 59 to move through the telescopic rod 514, thereby driving The gear 58 rotates, and the gear 58 drives the support shaft 510 to rotate, thereby driving the second clamping block 55 to rotate and clamp the first clamping block 54 close to each other. When the first handle 1 and the second handle 2 are released, the third spring 517 pulls the movable plate 513 to reset, and the second clamping block 55 and the first clamping block 54 are opened to each other, and the first handle 1 and the second handle 2 are closed, which solves the problem that when clamping foreign objects, the first handle 1 and the second handle 2 need to be opened for a long time by hand to keep the clamping claws open, which will cause discomfort and soreness in the hands for a long time, and increase the difficulty of operation for doctors;

[0052] When the clamping direction needs to be adjusted at the same time, the first clamping block 54 and the second clamping block 55 are rotated, and the first clamping block 54 is rotated on one side of the first internal threaded sleeve 53, and the telescopic rod 514 moves inside the semicircular groove 515 and the semicircular through groove 512 at the same time, while the movable plate 513 remains stationary inside the first internal threaded sleeve 53. Not only can the clamping claws of the clamping pliers be adjusted to different angles and the foreign matter can be clamped at the best clamping angle when clamping the foreign matter, but it also ensures that when the first clamping block 54 is rotated, the diamond wire 516 will not be affected by the rotation and cause the diamond wire 516 to break.

[0053] like Figure 7 As shown, the replacement component 56 includes an externally threaded rod 561 fixed on one side of the movable plate 513, a groove 565 is opened on one side of the externally threaded rod 561, and two trapezoidal blocks 562 are evenly slidably connected to the inner surface of the groove 565. The sides of the two trapezoidal blocks 562 close to each other are fixedly connected to the clamping plate 564, and a second internally threaded sleeve 563 is threadedly connected to the outer surface of the externally threaded rod 561.

[0054] The upper surface of the clamping plate 564 is evenly provided with anti-skid protrusions, and two groups of anti-skid protrusions are staggered with each other.

[0055] When the diamond wire 516 is used for a long time and breaks unexpectedly, it is necessary to replace the diamond wire 516 in time. The first internally threaded sleeve 53 is rotated to remove the first internally threaded sleeve 53 from the outer side of the externally threaded ring 7, and the second internally threaded sleeve 563 is rotated to make the second internally threaded sleeve 563 away from the two trapezoidal blocks 562, and the two trapezoidal blocks 562 are pulled apart from each other, and the remaining part of the diamond wire 516 is taken out from the inside of the groove 565, and one end of the new diamond wire 516 is inserted between the two clamping plates 564, and the second internally threaded sleeve 563 is rotated. One end of the second internally threaded sleeve 563 contacts the hypotenuse of the trapezoidal block 562 and pushes the trapezoidal block 562 to move toward the inside of the groove 565. The two clamping plates 564 approach each other to tightly clamp and fix one end of the diamond wire 516. At this time, the first internally threaded sleeve 53 is rotated back to the externally threaded ring 7, and the other end of the diamond wire 516 is wound around the fixed shaft 511 to ensure that the diamond wire 516 is in a straight state, so that the clamping forceps can continue to be used, thereby improving the reuse rate of the clamping forceps, reducing consumables of medical equipment, and making it easier to replace the diamond wire 516.

[0056] like Figure 8 As shown, the guide assembly 57 includes two vertical rods 571 fixed to the inner surface of the first internal threaded sleeve 53, and the two vertical rods 571 are fixedly connected to a connecting plate 572 on one side close to each other, and the connecting plate 572 is rotatably connected to two guide wheels 573 on one side close to each other, and the diamond wire 516 passes between the two guide wheels 573.

[0057] When the clamping pliers are in use, the diamond wire 516 plays a vital role. However, when the fixed shaft 511 is pulled by the diamond wire 516 to move the movable plate 513, the fixed shaft 511 and the replacement component 56 are in different vertical planes and staggered with each other, causing the diamond wire 516 to be in a tilted state between the fixed shaft 511 and the replacement component 56. When the diamond wire 516 is tilted, it will contact the edge of the first internal threaded sleeve 53. The diamond wire 516 is easily broken, which reduces the service life of the diamond wire 516. Therefore, two guide wheels 573 are set on the first internal threaded sleeve 53, so that the diamond wire 516 moves between the two guide wheels 573, so that the part of the diamond wire 516 close to the external threaded rod 561 is at the center of the first internal threaded sleeve 53, preventing the diamond wire 516 from contacting and rubbing with the edge of the first internal threaded sleeve 53, reducing the wear of the diamond wire 516, and improving the service life of the diamond wire 516.

[0058] like Fig. 9As shown, the fixing assembly 6 includes a through hole 61 opened on the outside of the first handle 1 and the second handle 2, and the second thorn racks 64 are fixedly connected to the two sides of the inner surface of the through hole 61, and the inside of the through hole 61 is slidably connected to the hollow rod 63, and the two sides of the hollow rod 63 are opened with through grooves 66, and the inside of the through groove 66 is slidably connected to the first thorn rack 62, and the first spring 67 is fixedly connected to the side where the two first thorn racks 62 are close to each other, and the bottom of the hollow rod 63 is fixedly connected to an arc-shaped clamping plate 65.

[0059] The first thorn rack 62 and the second thorn rack 64 are meshed with each other, a rubber pad is provided on one side of the arc-shaped clamping plate 65 , and a release assembly 68 is provided on the side of the hollow rod 63 away from the arc-shaped clamping plate 65 .

[0060] When a doctor uses the clamping forceps, due to the same specifications, different doctors may not be able to fit in well with each other. There is a large gap between the doctor's fingers and the ring parts of the first handle 1 and the second handle 2, which makes the opening and closing operations more laborious and the operation is easily deformed, which can easily cause accidental injuries to the patient when clamping foreign objects. Therefore, when the doctor uses the clamping forceps, when the doctor's fingers pass through the ring parts of the first handle 1 and the second handle 2, the hollow rod 63 is pushed to drive the arc splint 65 closer to the fingers, and the beveled edge of the teeth of the first thorn rack 62 slides with the beveled edge of the teeth of the second thorn rack 64. After the arc splint 65 squeezes and fixes the fingers, the first thorn rack 62 and the second thorn rack 64 are meshed and cannot move in the opposite direction, so that the fingers are fixed to each other with the first handle 1 and the second handle 2, so that the first handle 1 and the second handle 2 are more compatible with the fingers, and the first handle 1 and the second handle 2 move quickly with the movement of the fingers, so that the clamping forceps can be operated more accurately.

[0061] like Fig.10 As shown, the release assembly 68 includes a push rod 681 slidably connected to one side of the hollow rod 63, one side of the push rod 681 is hinged with two hinged rods 682, the outer surface of the push rod 681 is fixedly connected with a ring 683, and the outer surface of the push rod 681 is sleeved with a second spring 684.

[0062] The second spring 684 is located inside the hollow rod 63 , and two sides of the second spring 684 are fixedly connected to the hollow rod 63 and the ring 683 respectively. The hinge rod 682 and one side of the first thorn rack 62 are hinged to each other.

[0063] When not in use, the clamping forceps need to be removed from the fingers, and the push rod 681 is pushed to drive one end of the two hinged rods 682 to move. The two hinged rods 682 pull the two first thorn racks 62 closer to each other, so that the first thorn racks 62 and the second thorn racks 64 are separated from each other, and the fixation of the hollow rod 63 is released. The hollow rod 63 is pulled to drive the arc splint 65 to move, and the arc splint 65 is separated from the fingers to quickly separate the fingers from the clamping forceps, and the second spring 684 pushes the ring 683 to ensure that the push rod 681 is always in the initial position.

[0064] The working process provided by the present invention is as follows:

[0065] First, when using the clamping forceps, the first clamping block 54 can be rotated to flexibly adjust the clamping direction. When the diamond wire 516 is broken, the first internally threaded sleeve 53 can be removed from the externally threaded ring 7. The diamond wire 516 can be quickly clamped and fixed by the replacement component 56, which is convenient for replacing the diamond wire 516. At the same time, the guide component 57 can guide the diamond wire 516 to prevent the diamond wire 516 from contacting and rubbing with the edge of the first internally threaded sleeve 53.

[0066] Then, the doctor's fingers and the first handle 1 and the second handle 2 are fixed by the fixing component 6, so that the clamping forceps can fit the fingers more closely and can move quickly with the movement of the fingers, making the clamping forceps more adaptable. The releasing component 68 can quickly separate the first handle 1 and the second handle 2 from the fingers, and the operation is simple.

[0067] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0068] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
