[0047] As Figures 1 to 10As shown in the figure, an embodiment of the present invention provides a clamping forceps for removing foreign objects in the throat, which includes a first handle 1 and a second handle 2. One end of the first handle 1 is fixedly connected to a second bent portion 4, and one end of the second handle 2 is fixedly connected to a first bent portion 3. One end of the second bent portion 4 is fixedly connected to an external thread ring 7, the outer surface of the external thread ring 7 is connected with a rotary clamping assembly 5, and a fixing assembly 6 is connected to one side of the first handle 1 and the second handle 2.
[0048] As Figures 2 to 6 shown, the rotary clamping assembly 5 includes a first internal thread sleeve 53 threadedly connected to the surface of the external thread ring 7 and a rectangular frame 52 hinged to one end of the first bent portion 3. One side of the rectangular frame 52 is fixedly connected to a swing arm 51, the upper surface of the swing arm 51 is fixedly connected to a fixed shaft 511, a diamond wire 516 is wound around the outer surface of the fixed shaft 511, one side of the first internal thread sleeve 53 is rotatably connected to a first clamping block 54, one side of the first clamping block 54 is fixedly connected to a support shaft 510, 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 semi-circular through groove 512 is formed on one side inside the first internal thread sleeve 53, a moving plate 513 is slidably connected to the inner side wall of the first internal thread sleeve 53, a semi-circular groove 515 is formed on one side of the moving plate 513, a telescopic rod 514 is slidably connected to the inside of the semi-circular groove 515, and a rack 59 is fixedly connected to one side of the telescopic rod 514.
[0049] One side of the edge of the moving plate 513 is fixedly connected to a third spring 517. One side of the telescopic rod 514 passes through the inside of the semi-circular through groove 512 and slides. One side of the rack 59 extends below the gear 58 and meshes with the gear 58. A hinge shaft is provided at the hinge joint between the rectangular frame 52 and the first bent portion 3, and the hinge shaft is located inside the rectangular frame 52 and is mutually adapted. The swing arm 51 and the second bent portion 4 are hinged to each other, and the middle parts of the first handle 1 and the second handle 2 are hinged to each other.
[0050] The side of the moving plate 513 away from the telescopic rod 514 is connected with a replacement assembly 56, one side of the inner wall of the first internal thread sleeve 53 is connected with a guiding assembly 57, and the other end of the diamond wire 516 passes through the guiding assembly 57 and is connected with the replacement assembly 56.
[0051] Through the above technical solution, when using the clamping pliers, the first handle 1 and the second handle 2 are opened to drive the first bent part 3 and the second bent part 4 to rotate and cross each other. One end of the first bent part 3 drives one end of the swing arm 51 to rotate around the hinge point. The swing arm 51 drives the fixed shaft 511 to swing to one side. 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 internal thread sleeve 53, stretching the third spring 517. The first internal thread sleeve 53 pulls the rack 59 to move through the telescopic rod 514, thereby driving the gear 58 to rotate. The gear 58 drives the support shaft 510 to rotate, thereby driving the second clamping block 55 to rotate and approach the first clamping block 54 for clamping. When the first handle 1 and the second handle 2 are released, under the pulling of the third spring 517, the moving plate 513 is reset, the second clamping block 55 and the first clamping block 54 are opened, and the first handle 1 and the second handle 2 are closed, solving the problem that when clamping foreign objects traditionally, it is necessary to keep the first handle 1 and the second handle 2 open for a long time by hand to keep the clamping claws open, which will cause discomfort and soreness in the hand after a long time and increase the operation difficulty for doctors;
[0052] Meanwhile, when it is necessary to adjust the clamping direction, the first clamping block 54 and the second clamping block 55 are rotated. The first clamping block 54 rotates on one side of the first internal thread sleeve 53, and the telescopic rod 514 moves inside the semi-circular groove 515 and the semi-circular through groove 512 at the same time, while the moving plate 513 remains stationary inside the first internal thread sleeve 53. Not only can the clamping claws of the clamping pliers be adjusted to different angles to clamp foreign objects at the best clamping angle when clamping foreign objects, but also it is ensured 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] As Figure 7 shown, the replacement component 56 includes an external threaded rod 561 fixed to one side of the moving plate 513. A groove 565 is provided on one side of the external threaded rod 561. Two trapezoidal blocks 562 are evenly and slidably connected to the inner surface of the groove 565. A clamping plate 564 is fixedly connected to the side of the two trapezoidal blocks 562 that are close to each other. The external surface of the external threaded rod 561 is threadedly connected with a second internal thread sleeve 563.
[0054] Anti-slip protrusions are evenly arranged on the upper surface of the clamping plate 564, and the two groups of anti-slip protrusions are arranged staggeredly.
[0055] When the diamond wire 516 accidentally breaks during long-term use, it is necessary to replace the diamond wire 516 in a timely manner. Rotate the first internal thread sleeve 53 to remove the first internal thread sleeve 53 from the outside of the external thread ring 7. Rotate the second internal thread sleeve 563 so that the second internal thread sleeve 563 moves away from the two trapezoidal blocks 562. Pull the two trapezoidal blocks 562 apart from each other, and then take out the remaining part of the diamond wire 516 from the inside of the groove 565. Insert one end of the new diamond wire 516 between the two clamping plates 564. Rotate the second internal thread sleeve 563. One end of the second internal thread sleeve 563 contacts the hypotenuse of the trapezoidal block 562 and pushes the trapezoidal block 562 to move into the inside of the groove 565. The two clamping plates 564 move closer to tightly clamp and fix one end of the diamond wire 516. At this time, rotate the first internal thread sleeve 53 back onto the external thread ring 7, and wind the other end of the diamond wire 516 around the fixed shaft 511 to ensure that the diamond wire 516 is in a straightened state, so that the clamping pliers can continue to be used, improving the reuse rate of the clamping pliers, reducing the consumables of medical devices, and at the same time, the operation of replacing the diamond wire 516 is simpler.
[0056] As Figure 8 shown, the guiding assembly 57 includes two vertical rods 571 fixed to the inner surface of the first internal thread sleeve 53. Connecting plates 572 are fixedly connected to the sides of the two vertical rods 571 close to each other. Two guiding wheels 573 are rotatably connected to the sides of the connecting plates 572 close to each other. The diamond wire 516 passes between the two guiding wheels 573.
[0057] When the clamping pliers are in use, the diamond wire 516 plays a crucial role. However, when the fixed shaft 511 pulls the moving plate 513 to move through the diamond wire 516, the fixed shaft 511 and the replacement assembly 56 are offset from each other in different vertical planes, causing the diamond wire 516 to be in an inclined state between the fixed shaft 511 and the replacement assembly 56. When the diamond wire 516 is inclined, it will contact the edge of the first internal thread sleeve 53, and the diamond wire 516 is easily broken, reducing the service life of the diamond wire 516. Therefore, two guiding wheels 573 are provided on the first internal thread sleeve 53, so that the diamond wire 516 moves between the two guiding wheels 573, making the part of the diamond wire 516 close to the external threaded rod 561 be at the center of the first internal thread sleeve 53, preventing the diamond wire 516 from contacting and rubbing against the edge of the first internal thread sleeve 53, reducing the wear of the diamond wire 516, and increasing the service life of the diamond wire 516.
[0058] As Figure 9As shown, the fixing component 6 includes through holes 61 formed on the outer sides of the first handle 1 and the second handle 2. On both sides of the inner surface of the through hole 61, second barbed racks 64 are fixedly connected. A hollow rod 63 is slidably connected inside the through hole 61. Through grooves 66 are formed on both sides of the hollow rod 63. First barbed racks 62 are slidably connected inside the through grooves 66. On one side of the two first barbed racks 62 close to each other, a first spring 67 is fixedly connected. At the bottom of the hollow rod 63, an arc-shaped clamping plate 65 is fixedly connected.
[0059] The first barbed rack 62 and the second barbed rack 64 mesh with each other. A rubber pad is arranged on one side of the arc-shaped clamping plate 65. On the side of the hollow rod 63 away from the arc-shaped clamping plate 65, a releasing component 68 is arranged.
[0060] When a doctor uses the clamping forceps, due to the same specifications, but different doctors have a low degree of cooperation when using them. There is a large gap between the doctor's fingers and the ring parts of the first handle 1 and the second handle 2. It is more laborious and the operation is prone to deformation during the opening and closing operations. It is very easy to cause accidental injuries to patients when clamping foreign objects. Therefore, when a doctor uses the clamping forceps and the 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-shaped clamping plate 65 to approach the fingers. The hypotenuse of the teeth of the first barbed rack 62 slides with the hypotenuse of the teeth of the second barbed rack 64. When the arc-shaped clamping plate 65 squeezes and fixes the fingers, the first barbed rack 62 and the second barbed rack 64 mesh and cannot move in the reverse direction, so that the fingers are fixed to the first handle 1 and the second handle 2, making the first handle 1 and the second handle 2 more adapted to the fingers, and enabling the first handle 1 and the second handle 2 to move quickly with the movement of the fingers, making the operation of the clamping forceps more accurate.
[0061] As Figure 10 As shown, the releasing component 68 includes a push rod 681 slidably connected to one side of the hollow rod 63. Two hinge rods 682 are hinged to one side of the push rod 681. A ring 683 is fixedly connected to the outer surface of the push rod 681. A second spring 684 is sleeved on the outer surface of the push rod 681.
[0062] The second spring 684 is located inside the hollow rod 63. Both sides of the second spring 684 are fixedly connected to the hollow rod 63 and the ring 683 respectively. The hinge rod 682 is hinged to one side of the first barbed rack 62.
[0063] When not in use, the clamping pliers need to be removed from the finger. Push the push rod 681 to drive one end of the two hinge rods 682 to move. The two hinge rods 682 pull the two first thorn racks 62 closer to each other, causing the first thorn rack 62 and the second thorn rack 64 to separate from each other, releasing the fixation of the hollow rod 63. Pull the hollow rod 63 to drive the arc-shaped clamping plate 65 to move, separating the arc-shaped clamping plate 65 from the finger and quickly separating the finger from the clamping pliers. 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 pliers, the first clamping block 54 can be rotated to flexibly adjust the clamping direction. When the diamond wire 516 breaks, the first internal thread sleeve 53 can be removed from the external thread ring 7. The diamond wire 516 can be quickly clamped and fixed through the replacement component 56, facilitating the replacement of the diamond wire 516. At the same time, the guiding component 57 can guide the diamond wire 516 to prevent the diamond wire 516 from contacting and rubbing against the edge of the first internal thread sleeve 53.
[0066] Then, through the fixing component 6, the doctor's finger, the first handle 1 and the second handle 2 are fixed, which can make the clamping pliers fit the finger better, move quickly with the movement of the finger, and make the adaptability of the clamping pliers higher. The releasing component 68 can quickly separate the first handle 1 and the second handle 2 from the finger, and the operation is simple.
[0067] The present invention covers any alternatives, modifications, equivalent methods and solutions made within the essence and scope of the present invention. For the public to have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention. However, those skilled in the art can fully understand the present invention without these detailed descriptions. In addition, well-known methods, processes, procedures, components and circuits are not described in detail to avoid unnecessary confusion to the essence of the present invention.
[0068] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
