Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an orthopedic nail removal device with a base having a stable structure. Background Art

[0002] Orthopedic nail removal is a common procedure in orthopedic surgery. It is mainly used to remove metal fixtures such as fixation screws and intramedullary nails that were previously implanted in the body after fracture healing. This process usually requires local or general anesthesia. The doctor enters the body through the original surgical incision and uses special tools to unscrew or remove the fixture. Due to factors such as the complex bone structure, large individual differences, and limited operating space, orthopedic nail removal often involves certain technical difficulties and risks. Therefore, during the nail removal process, ensuring the stable fixation of the patient's limb is of great significance to improving surgical efficiency and reducing operational risks.

[0003] Orthopedic nail removal devices occupy a crucial position in the field of orthopedic medical devices. As a key auxiliary device, their structural design and stability have a decisive impact on the overall surgical effectiveness and safety. In particular, existing orthopedic nail removal devices have gradually exposed a series of significant limitations and technical issues in the core process of intraoperative fixation of the patient's limb.

[0004] Specifically, existing orthopedic nail removal devices commonly struggle to stabilize the patient's limb in practical applications. Traditional nail removal devices often utilize simple support structures or rely on manual support from medical staff, making them difficult to flexibly adjust and precisely secure based on the patient's body shape, limb length, and surgical site. This lack of stability can easily lead to slight movement or shaking of the patient's limb during the nail removal procedure, increasing the difficulty of operating the instrument and potentially causing misoperation, resulting in soft tissue damage or other complications. Furthermore, existing devices lack adaptability to different surgical positions and fail to provide reliable support, further exacerbating the uncertainty of the nail removal operation. These issues directly lead to reduced surgical efficiency, increased operational complexity for physicians, and difficulty meeting clinical requirements for high precision and safety. More seriously, operational errors caused by insecure limb fixation not only significantly increase the patient's pain and postoperative recovery time, but also pose potential risks to the overall quality and safety of the surgery. Therefore, given the many shortcomings of the existing technology, an innovative orthopedic nail removal device is urgently needed to address these challenges. Summary of the Invention

[0005] The purpose of the present invention is to provide an orthopedic nail removal device with a stable base structure, which solves the problem that the nail removal devices in the prior art mostly use simple support structures or rely on manual support from medical staff, which is difficult to flexibly adjust and accurately fix according to the body shape, limb length and surgical site of different patients. It is easy to cause slight movement or shaking of the patient's limbs during the nail removal operation, thereby increasing the difficulty of operating the instrument and may even cause misoperation, resulting in soft tissue damage or other complications.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The invention discloses an orthopedic nail removal device with a stable base structure, comprising a frame body, a supporting plate slidably connected to the inner side of the frame body, and a plurality of arc-shaped plates fixedly connected to the top of the supporting plate, and a top frame fixedly connected to the top of the frame body, a screw rod rotatably connected to the inner side of the top frame, and a driving motor fixedly connected to one side of the outer wall of the top frame by a bolt, and one end of the screw rod passes through one side of the top frame and is transmission-connected to the output shaft of the driving motor, and one end of the screw rod is screwed through a nut seat by threaded engagement, and an arc-shaped pressure plate is fixedly connected to the bottom of the nut seat, and the arc-shaped pressure plate is located on the top of the supporting plate.

[0008] Preferably, sliders are fixedly connected to both sides of the carrying plate, and both sliders are slidably connected to the inner wall of the frame through sliding grooves.

[0009] Preferably, one side of the two sliders is fixedly connected to a base plate, and the top of the two base plates is provided with a top plate fixedly connected to the frame, and the top of the two top plates is fixedly connected to a cylinder by bolts, wherein the output shafts of the two cylinders respectively pass through the two top plates and are fixedly connected between the tops of the two base plates.

[0010] Preferably, both sides of the carrying plate are fixedly connected with connecting plates, and one side of the two connecting plates is fixedly connected with a slide plate, and one end of the two slide plates is slidably connected to the side wall of the frame through the vertical groove.

[0011] Preferably, support rods are provided on both sides of the frame, and one end of the two support rods passes through the side wall of the frame and the two slides in sequence. A tension spring is sleeved on one end of the two support rods, and one end of the support rod is elastically connected to the side wall of the frame through the tension spring.

[0012] Preferably, one end of the screw is rotatably connected to the inner wall of the top frame through a rotating shaft, and the other end of the screw passes through the side wall of the top frame through a bearing sleeve. A sliding block is fixedly connected to the top of the nut seat, and the sliding block is slidably connected to the top of the top frame through a sliding groove.

[0013] The present invention has at least the following beneficial effects:

[0014] The present invention realizes the rapid and stable fixation of the patient's limbs by arranging a combined structure of a bearing plate and an arc plate, combined with the arc-shaped pressure plate on the top and the driving mechanism, effectively solving the problem of inconvenience in stabilizing the limbs in the prior art, and significantly improving the stability and safety of the nail removal operation; secondly, the screw driven by the driving motor drives the nut seat and the arc-shaped pressure plate to move up and down, thereby realizing automatic clamping control, reducing the uncertainty caused by the traditional reliance on manual support of medical staff, reducing the complexity of operation, and improving the efficiency of surgery; thirdly, the structure has good adjustable adaptability, and the clamping force can be flexibly adjusted by controlling the motor speed and stroke. The device can be adjusted to different degrees and positions to meet the clinical application needs of different body shapes, different parts and different postures, thereby enhancing the versatility and practicality of the device. In addition, the design effectively avoids the risk of operational errors caused by loose limb fixation, reduces the possibility of accidental injury to soft tissue, thereby reducing the patient's intraoperative discomfort and the incidence of postoperative complications, and further ensuring the overall quality and safety of the operation. In summary, the device not only overcomes the shortcomings of the existing orthopedic nail removal devices in structural design, but also, based on actual clinical needs, improves the humanization and intelligence level of the equipment, and provides reliable technical support for the efficient and safe implementation of orthopedic surgery.
