Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and more specifically, to a head traction hammer kit and a head traction hammer medical device. Background Technology
[0002] Currently, during cranial traction surgery, a traction brace needs to be fixed to the patient's head. Figure 1 As shown in the diagram, the traction frame is connected to multiple counterweights via traction ropes. When the weight of the counterweights acts on the head, the skull is compressed, thereby pulling on the cervical spine and relieving nerve compression caused by cervical spine problems.
[0003] During skull traction, the traction weight should be determined according to the doctor's orders, taking into account factors such as the patient's age, muscle development, type of traction used, traction site, duration of injury, extent, severity, and type of trauma. Furthermore, the traction force needs continuous adjustment during the process. A heavier weight is applied initially for the first 24-48 hours to quickly pull the fracture ends apart, followed by maintaining traction with a lighter weight. Different counterweights need to be changed during this process; therefore, in hospital settings, the counterweights are usually moved manually by medical staff.
[0004] If the weight of a single counterweight is relatively light, it is not a problem to move it. However, the traction weight depends on the cervical spine fracture and dislocation. Sometimes the weight of a single counterweight is relatively large, and it is obviously very difficult to move the counterweight by hand.
[0005] Therefore, existing technologies need to be improved. Utility Model Content

[0047] Please see Figure 2 and Figure 3 This embodiment provides a head traction hammer kit, which includes: a support base 100, a plurality of counterweights 200 and an auxiliary transfer rod 300. The support base 100 has a storage space 140. The counterweights 200 are stacked in the storage space 140 to increase the weight of the support base 100. The auxiliary transfer rod 300 is used to cooperate with the counterweights 200 so that the auxiliary transfer rod 300 drives the counterweights 200 to move.
[0048] Please combine Figure 1 As shown, during skull traction, the traction weight should be determined according to the doctor's advice, taking into account factors such as the patient's age, muscle development, type of traction used, traction site, duration of injury, extent, severity, and type of trauma. Simultaneously, the traction force needs continuous adjustment during the traction process. A heavier weight is applied initially for the first 24-48 hours to quickly pull the fracture ends apart, followed by maintaining traction with a lighter weight. During this process, different counterweights (200) need to be changed. Since a single counterweight (200) may be quite heavy, it can easily lead to difficulties in moving it.
[0049] In this embodiment, the head traction hammer kit includes a support base 100, several counterweights 200, and an auxiliary transfer rod 300. The auxiliary transfer rod 300 serves as a special tool for moving the counterweights 200, which can reduce the difficulty of moving, save effort, and improve work efficiency.
[0050] For example, when the total traction weight required is large, multiple counterweights 200 can be used in combination to meet clinical traction needs. An auxiliary transfer rod 300 is connected to each individual counterweight 200, and then the auxiliary transfer rod 300 is used to move each counterweight 200 sequentially into the storage space 140 of the support base 100. This reduces the difficulty for medical staff in moving the counterweights 200, saves their effort, and improves work efficiency. This device is suitable for moving counterweights 200 of different sizes and weights.
[0051] The support base 100 is used to connect with the traction rope 410 of the traction bracket 400. The support base 100 has a storage space 140 for accommodating the counterweight 200 to prevent the counterweight 200 from slipping off the support base 100, thus ensuring the safe use of the head traction hammer.
[0052] Therefore, in this embodiment, the head traction hammer kit can move the counterweight 200 into the storage space 140 of the bearing base 100 through the auxiliary transfer rod 300, which can reduce the difficulty of medical staff moving the counterweight 200, save medical staff's strength, improve work efficiency, and is simple to operate, convenient to use, and highly safe.
[0053] Specifically, please refer to Figure 3The counterweight 200 includes a counterweight disc 210, a central connecting hole 240, a strip notch 230, and a limiting rib 220. The central connecting hole 240 is located at the center of the counterweight disc 210. The strip notch 230 extends from the edge of the counterweight disc 210 to the central connecting hole 240 and is connected to the central connecting hole 240. The limiting rib 220 is provided on the counterweight disc 210 and is used to limit the sliding of the counterweight disc 210.
[0054] In this embodiment, the counterweight disc 210 is equivalent to the counterweight block 200 having a disc-shaped structure. This design, without sharp edges, eliminates the risk of injury to medical personnel due to accidental bumps during use, thus avoiding injury, saving space, and improving comfort and safety during use. It should be understood that the shape of the counterweight block 200 is not limited to the disc shape described above; the shape of the counterweight block 200 can also be other forms, which are not limited here.
[0055] The central connecting hole 240 is located at the center of the counterweight disc 210. The central connecting hole 240 is used to install the counterweight disc 210. For example, when the counterweight block 200 is moved, the second rod 330 can pass through the central connecting hole 240 to realize that the second rod 330 can connect multiple stacked counterweight blocks 200 in series. Alternatively, when the counterweight disc 210 is placed in the storage space 140, the traction rod 120 can pass through the central connecting hole 240 to realize that the traction rod 120 can connect multiple stacked counterweight blocks 200 in series.
[0056] The strip-shaped notch 230 extends from the edge of the counterweight disc 210 towards the central connecting hole. The strip-shaped notch 230 can be understood as the entrance to the central connecting hole, facilitating the passage of the auxiliary transfer rod 300 and the traction rod 120 through the central connecting hole. When the auxiliary transfer rod 300 is needed to move the counterweight disc 210, the second rod 330 of the auxiliary transfer rod 300 can be inserted into the central connecting hole through the strip-shaped notch 230; or, when the traction rod 120 needs to connect multiple stacked counterweight blocks 200 in series, the strip-shaped notch 230 can be aligned with the traction rod 120, and then the counterweight disc 210 can be pushed toward the traction rod 120, so that the traction rod 120 is placed inside the central connecting hole.
[0057] The limiting rib 220 is used to restrict the sliding of the counterweight disc 210. For example, the bottom of the counterweight disc 210 is provided with a first rib (not shown in the figure), and the top of the counterweight disc 210 is provided with a second rib. When two counterweight discs 210 are stacked and assembled, the second rib of the lower counterweight disc 210 can be embedded in the first rib of the upper counterweight disc 210, or the first rib of the upper counterweight disc 210 can be embedded in the second rib of the lower counterweight disc 210. In this way, the second rib and the first rib abut against each other to prevent the upper counterweight disc 210 and the lower counterweight disc 210 from sliding against each other.
[0058] Specifically, please refer to Figure 2 The supporting base 100 includes: a first base plate 110, a traction rod 120, and a guardrail 130. The first base plate 110 is used to abut against the counterweight 200. The traction rod 120 is located in the middle of the first base plate 110. The guardrail 130 is located around the first base plate 110. The guardrail 130 is connected to the first base plate 110 to form a storage space 140.
[0059] In this embodiment, a traction rod 120 and a guardrail 130 are provided on the first base plate 110. The traction rod 120 is used to connect with the traction rope 410 of the traction bracket 400, serving to connect the bearing base 100 and the traction bracket 400. The first base plate 110 and the guardrail 130 are connected to form a storage space 140 for accommodating the counterweight 200. The guardrail 130 serves a protective function to prevent medical staff or other personnel from touching the counterweight 200, which could cause the counterweight 200 to detach from the bearing base 100. For example, if medical staff accidentally touch the counterweight 200, it may fall, which could interrupt traction treatment or even cause the counterweight 200 to hit other people. Therefore, the guardrail 130 can ensure the safe use of the counterweight 200.
[0060] Specifically, please refer to Figure 2 The first base plate 110 includes a first disc 111, a traction rod 120 is provided in the middle of the first disc 111, and a guardrail 130 is provided around the first disc 111.
[0061] In this embodiment, the first base plate 110 includes a first disc 111, that is, the first base plate 110 is made of a disc structure. The disc structure has no sharp edges, which eliminates the risk of medical staff being injured by accidental bumps during use. It can avoid injury, save space, improve aesthetics, and improve comfort and safety during use.
[0062] Specifically, please refer to Figure 2 The traction rod 120 includes a first rod body 121 and a pull ring 122. The first rod body 121 is fixed to the middle position of the first base plate 110, and the pull ring 122 is disposed at the end of the first rod body 121 away from the first base plate 110.
[0063] In this embodiment, the first rod 121 is used to connect the first base plate 110, and the pull ring 122 is used to connect the first rod 121 to the traction rope 410 of the traction bracket 400. For example, the traction rope 410 can be provided with a hook 340, which is connected to the pull ring 122 through the hook 340. The structure is simple, the connection is stable, the operation is convenient, and the use is easy.
[0064] Specifically, please refer to Figure 2 The guardrail 130 includes a fence 132 composed of several guard rods 131 and a capping ring 133. The fence 132 is fixed around the first base plate 110, and the capping ring 133 is located at the end of the fence 132 away from the first base plate 110.
[0065] In this embodiment, the fence 132 and the capping ring 133 are used to form an open storage space 140, which plays a protective role and prevents medical staff or other personnel from touching the counterweight 200 and causing the counterweight 200 to fall off the bearing base 100. At the same time, the fence 132 has a hollow structure, which can provide operating space for moving the counterweight 200.
[0066] Specifically, please refer to Figure 2 The auxiliary transfer rod 300 includes: a second base plate 310, a base plate rib 320, a second rod body 330, and a hook 340. The second base plate 310 is used to abut against the counterweight 200. The base plate rib 320 is disposed on the second base plate 310 and is used to connect with the counterweight 200 to limit the sliding of the counterweight 200. The second rod body 330 is disposed at the middle position of the second base plate 310 and is used to cooperate with the counterweight 200 so that the second base plate 310 can bear the counterweight 200. The hook 340 is disposed at the end of the second rod body 330 away from the second base plate 310.
[0067] In this embodiment, the second rod 330 is disposed on the second base plate 310, which is used to abut against the counterweight 200. When moving the counterweight 200, medical staff can hold the second rod 330 so that the second base plate 310 can support the counterweight 200. Alternatively, other auxiliary tools can be used to pull the second rod 330 so that the second base plate 310 can bear the counterweight 200, which is highly safe.
[0068] The bottom plate rib 320 is provided on the second bottom plate 310. The bottom plate rib 320 has the function of strengthening the structural strength of the second bottom plate 310 and restricting the sliding of the counterweight 200. The bottom plate rib 320 can abut against the counterweight 200 to prevent the counterweight 200 from sliding. For example, the bottom of the counterweight 200 can be provided with a limiting rib 220. When the second rod 330 passes through the central connecting hole, the limiting rib 220 can be embedded in the bottom plate rib 320, or the bottom plate rib 320 can be embedded in the limiting rib 220 to achieve mutual abutment between the limiting rib 220 and the bottom plate rib 320, preventing the counterweight 200 from sliding on the second bottom plate 310. The hook 340 is located at the end of the second rod 330 away from the second base plate 310. The hook 340 can be easily gripped to prevent the second rod 330 from falling out of the hands of medical staff. At the same time, the hook 340 can be easily connected to other auxiliary tools.
[0069] Specifically, please refer to Figure 2 and Figure 3 The second base plate 310 includes a second disk 311, and the diameter of the second disk 311 is smaller than the diameter of the counterweight 200.
[0070] In this embodiment, the auxiliary transfer rod 300 is used to assist in moving the counterweight 200. For example, please refer to... Figure 4 The counterweight 200 can be transferred to the storage space 140 by the auxiliary transfer rod 300. When the auxiliary transfer rod 300 moves the counterweight 200 into the storage space 140, the center connecting hole of the counterweight 200 needs to be disengaged from the second rod 330 and connected to the traction rod 120. First, the strip notch 230 is moved away from the traction rod 120, and the second rod 330 is moved outward along the strip notch 230 so that the second rod 330 is disengaged from the counterweight 200. Then, the counterweight 200 is rotated so that the strip notch 230 faces the traction rod 120. Then, the counterweight 200 is pushed so that the strip notch 230 moves along the traction rod 120 until the traction rod 120 is placed in the center connecting hole. The diameter of the second disc 311 is smaller than the diameter of the counterweight 200. This minimizes the diameter of the first disc 111, reducing the space occupied by the bearing base 100. For example, the diameter of the first disc 111 is D1, and the diameter of the counterweight 200 is D3. D1 is slightly larger than twice D3, allowing the counterweight 200 to be moved within the fence 132, thus ensuring high safety.
