Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a removal forceps for a circumferential rib fixator. Background Art

[0002] In the modern medical field, fracture treatment has become a common clinical treatment method. Among them, the use of a rib fixator (whose shape is like Figure 3 ) plays a crucial role in the treatment of thoracic injuries. However, in the prior art, due to the lack of a dedicated removal tool, there are still many problems in the removal process of the rib fixator.

[0003] The traditional method for removing a rib fixator usually uses ordinary medical forceps for clamping. However, ordinary medical forceps can only clamp one end of the splint of the rib fixator and cannot provide sufficient reaction force, making the removal process extremely difficult and prone to causing secondary injuries to patients. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a removal forceps for a circumferential rib fixator aiming at the above deficiencies existing in the prior art. The removal forceps for a circumferential rib fixator can act on both sides of the rib fixator simultaneously through reaction force, making the removal process of the rib fixator easier and safer.

[0005] To solve the above problems, the utility model adopts the following technical scheme:

[0006] A removal forceps for a circumferential rib fixator includes a fixed seat and movable rods. There are two movable rods, which are rotatably installed on both sides of the top of the fixed seat. An operation handle is fixedly installed at the top end of the movable rod, and a hook part with adjustable length is fixedly installed at the bottom end. The bottom end face of the fixed seat is an arc adapted to the arc-shaped main board of the rib fixator. When clamping the rib fixator, the bottom end face of the fixed seat is lapped on the arc-shaped main board of the rib fixator, and the hook part hooks the splint of the rib fixator.

[0007] Preferably, a rubber pad is embedded in the bottom end face of the fixed seat.

[0008] Preferably, the two movable rods are symmetrically distributed on both sides of the fixed seat and can rotate along their connection points with the fixed seat.

[0009] Preferably, the hook part includes a hollow rod and an adjusting rod. The hollow rod is fixedly installed at the lower end of the movable rod, and the adjusting rod is slidably arranged in the hollow rod, and the bottom end of the adjusting rod is in a hook shape for hooking the splint of the circumferential rib fixator.

[0010] Preferably, the hooking portion further comprises a screw rod, which is threadedly connected to the hollow rod, and one end of the screw rod located inside the hollow rod is rotatably connected to the adjusting rod via a bearing.

[0011] Preferably, the thickness of the adjusting rod gradually decreases from one end close to the hollow rod to the other end.

[0012] Preferably, the adjusting rod is made of PVC.

[0013] Preferably, the operating handle is arc-shaped.

[0014] Preferably, the surface of the operating handle is covered with an anti-slip cover.

[0015] The embracing rib fixator removal forceps of the utility model are equivalent to a reaction force pliers, which act on both sides simultaneously to pry open the splints of the rib fixator with force in opposite directions, thereby making the rib fixator removal process easier and safer. This design overcomes the problems that traditional medical forceps can only clamp one end, have uneven force, and are prone to secondary injuries. The position of the adjustment rod is adjustable, and the doctor can adjust the position of the adjustment rod according to the specific size and shape of the rib fixator to ensure that the adjustment rod can effectively hook the splints of the rib fixator, thereby providing sufficient reaction force during the removal process.

[0024] The present utility model provides a circumferential rib fixator removal forceps, which includes a fixed seat and a movable rod. There are two movable rods, and the two movable rods are rotatably installed on both sides of the top of the fixed seat. An operation handle is fixedly installed at the top end of the movable rod, and an adjustable-length hook portion is fixedly installed at the bottom end. The bottom end surface of the fixed seat is an arc adapted to the arc-shaped main board of the rib fixator. When clamping the rib fixator, the bottom end surface of the fixed seat is lapped on the arc-shaped main board of the rib fixator, and the hook portion hooks the splint of the rib fixator.

[0025] Embodiment 1

[0026] As Figures 1-3 shown, this embodiment discloses a circumferential rib fixator removal forceps for removing the circumferential rib fixator of a rib fracture patient. The circumferential rib fixator includes an arc-shaped main board and a plurality of splints distributed on both sides of the main board. The circumferential rib fixator removal forceps includes a fixed seat 1 and a movable rod 2. There are two movable rods 2, and the two movable rods 2 are rotatably installed on both sides of the top of the fixed seat 1. An operation handle 3 is fixedly installed at the top end of the movable rod 2, and an adjustable-length hook portion is fixedly installed at the bottom end. The bottom end surface of the fixed seat 1 is an arc adapted to the arc-shaped main board of the rib fixator 8. When clamping the rib fixator 8, the bottom end surface of the fixed seat 1 is lapped on the arc-shaped main board of the rib fixator 8, and the hook portion hooks the splint of the rib fixator 8.

[0027] Specifically, the bottom end surface of the fixing base 1 is an arc-shaped notch, and the shape of the arc-shaped notch is completely consistent with the arc shape of the back side of the mainboard of the rib fixer 8, and an elastic rubber pad 6 is embedded inside the arc-shaped notch. The rubber pad 6 can provide greater friction. When the bottom end surface of the fixing base 1 contacts the mainboard of the rib fixer 8, the rubber pad 6 can increase the stability of the device and prevent sliding or displacement during the removal of the rib fixer 8.

[0028] like Figure 1 , 2 As shown, the two movable rods 2 are symmetrically distributed on both sides of the fixing base 1, and can be rotated along the connection point with the fixing base 1 to adjust the position of the hook part to match the size of the rib fixer 8, so that the hook parts on both sides are synchronously clamped on the splint of the rib fixer 8.

[0029] like Figure 1 , 2 As shown, the hooking part includes a hollow rod 4 and an adjusting rod 5. The hollow rod 4 is fixedly installed at the lower end of the movable rod 2. The adjusting rod 5 is slidably arranged in the hollow rod 4, so as to be used to adjust the position of the adjusting rod, and the bottom end of the adjusting rod 5 is in a hook shape, which is used to hook the splint of the embracing rib fixer 8.

[0030] Specifically, the interior of the hollow rod 4 is a cavity, the middle part of which is fixedly mounted on the lower end of the movable rod 2, and the hollow rod 4 is perpendicular to the movable rod 2, and the adjusting rod 5 is slidably arranged in the internal cavity of the hollow rod 4. The hooking portion also includes a screw 7, which is arranged through one end of the hollow rod 4 and is threadedly connected to the hollow rod 4, and the end of the screw 7 located inside the hollow rod 4 is rotatably connected to the adjusting rod 5 through a bearing. The sliding connection between the adjusting rod 5 and the hollow rod 4 allows the adjusting rod 5 to move along the axial direction of the hollow rod 4. This design can achieve very fine adjustment, ensuring that the adjusting rod 5 can accurately correspond to the position and size of the rib fixer 8. Furthermore, one end of the hollow plate is threadedly connected to the screw 7, and the screw 7 rotates along the thread to achieve a change in position, and moves linearly along the axis of the thread, thereby pushing or pulling the adjusting rod 5.

[0031] Optionally, the thickness of the adjustment rod 5 gradually decreases from one end close to the hollow rod 4 to the other end. That is, the thickness of the end in contact with the patient and the rib fixator 8 is thinner, because the thinner end is more conducive to being embedded between the patient's skin and the splint of the rib fixator 8 on the one hand, and on the other hand, when contacting the patient's skin and soft tissue, due to its lighter weight and smaller pressure, it can reduce the pressure on the patient and improve the patient's comfort.

[0032] Optionally, the material of the adjusting rod 5 is PVC, and the bending portion of the bottom end (hook-shaped) of the adjusting rod 5 adopts an arc-shaped transition. The arc shape is conducive to dispersing pressure and reducing local stress concentration, thereby protecting the patient from injury by sharp edges. This shape also helps to more smoothly guide the rib fixator 8 through the bottom end of the adjusting rod 5, making it easier to remove the rib fixator 8.

[0033] like Figure 1 , 2 As shown, the operating handle 3 is arc-shaped. Specifically, the arc-shaped operating handle 3 imitates the arc of a natural hand-holding posture, which can make the doctor more comfortable to use and reduce fatigue of the wrist and arm. This design is conducive to improving the accuracy and stability of the operation during the operation. At the same time, the arc-shaped operating handle 3 can provide a larger force arm than a straight rod, which helps the doctor to make fine force adjustments and ensure that the action when removing the rib fixator is both stable and controllable.

[0034] Furthermore, the surface of the operating handle 3 is provided with an anti-slip cover, which can be made of rubber or other materials with a high friction coefficient. This design can prevent the doctor's hands from slipping during the surgical operation, especially when a large force is required to remove the rib fixator 8, which can ensure better grip and safe operation.

[0035] The use principle of the encircling rib fixator removal forceps in this embodiment is as follows:

[0036] First, according to the specific conditions of the patient and the size and shape of the rib fixator 8, the position of the adjusting rod 5 is adjusted to match the size and position of the rib fixator; specifically, by rotating the screw rod 7, the screw rod 7 moves along the thread between the screw rod 7 and the hollow rod 4, thereby pushing or pulling the adjusting rod 5;

[0037] Then, the bottom end surface of the fixing base 1 of the removal pliers is pressed against the back of the main board of the rib fixer so that the arc-shaped notch fits with the arc surface of the main board;

[0038] Align the adjusting rod 5 of the extraction pliers with the splint of the rib fixer, and then control the movable rod 2 to rotate by the operating handle 3, so that the hook portion at the bottom end of the adjusting rod 5 hooks the splint; specifically, when the two operating handles 3 are controlled to approach each other, the upper parts of the movable rods 2 approach each other, and the lower parts of the movable rods 2 move away from each other. At this time, the hook portion at the bottom end of the adjusting rod 5 moves outward to hook the splint;

[0039] Finally, the operating handles 3 are further controlled to move closer to each other, and the movable rod 2 is further opened, so that the two side splints of the rib fixator are stretched open, so as to facilitate the removal of the rib fixator from the patient's body; if there is a large resistance or the patient feels pain during this process, the position of the adjusting rod 5 can be adjusted to change the contact area between the adjusting rod 5 and the rib fixator, thereby changing the removal force to ensure the safety and comfort of the removal process.

[0040] The embracing rib fixator removal forceps in this embodiment are equivalent to a reaction force forceps, which act on both sides simultaneously to pry open the splints of the rib fixator with force in opposite directions, thereby making the rib fixator removal process easier and safer. This design overcomes the problem that traditional medical forceps can only clamp one end, have uneven force, and are prone to secondary injuries. The position of the adjustment rod 5 is adjustable. The doctor can adjust the position of the adjustment rod according to the specific size and shape of the rib fixator to ensure that the adjustment rod can effectively hook the splints of the rib fixator, thereby providing sufficient reaction force during the removal process.

[0041] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
