Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a shoulder joint auxiliary reduction device. Background Art

[0002] In the traditional treatment of shoulder dislocation, although a variety of manual reduction techniques have been widely used, such as the Hippocrates method, there are still some significant technical problems in actual clinical operation. These problems are mainly manifested in the following two aspects:

[0003] Manual reduction technique is highly dependent on the physician's experience and practical skills. This technique requires high professionalism from the physician and requires precise control of the direction and strength of the force during operation. However, due to differences in clinical experience and personal understanding, the success rate of reduction has certain fluctuations. In the case of insufficient experience or poor skills, the physician may find it difficult to ensure that the direction and strength of the force are optimal, resulting in failure or delay of the reduction attempt. In addition, there are variations in the anatomical structures of different patients, including the laxity and muscle condition of the shoulder joint, which further increases the uncertainty of the reduction operation. Therefore, this traditional method that is highly dependent on experience may be difficult to ensure the timeliness and effectiveness of reduction in some cases.

[0004] During the traditional manual reduction process, patients often face great pain and discomfort. This pain is not only caused by the dislocation itself, but also related to the external force applied during the reduction process. It is difficult for doctors to accurately control the location and intensity of the force during manual reduction, which may cause additional pulling and damage to soft tissues, and even induce muscle spasms. In addition, the lack of effective auxiliary equipment to stabilize the patient's body posture and reduce the pressure during the force application process will further aggravate the patient's discomfort. In some complex cases, general anesthesia or muscle relaxants may be required to reduce pain, which increases the complexity and potential risks of treatment, especially in environments with limited resources or where patients are not suitable for anesthesia, which increases the difficulty of operation and medical risks.

[0005] In summary, the existing manual reduction technology for shoulder dislocation is difficult to ensure efficient and safe treatment effects in all cases due to the high experience requirements of doctors and insufficient attention to patient comfort and safety. This shows that it is necessary to develop a new auxiliary reduction device to help doctors improve operating efficiency, while improving patient experience, reducing pain and potential injury risks. By providing a more stable and adjustable force application scheme, such a device can provide a more reliable and comfortable solution for the reduction of shoulder dislocation. Summary of the invention

[0009] Furthermore, the outer sides of the outer tube and the arm arc plate are provided with silicone pads for the medical staff's feet to bear force; the silicone pad of the outer tube is provided with an arc-shaped protrusion on the side close to the arm arc plate, and the silicone pad of the arm arc plate is provided with an arc-shaped depression on the side close to the outer tube; the arm arc plate is rotatably connected to the inner rod through a rotating shaft, and the rotating shaft is provided with a tightening screw for fixing the rotation position of the arm arc plate.

[0010] Furthermore, the inner side surface of the arm arc plate is arc-shaped to adapt to the physiological curvature of the human arm, and the inner side surface of the rib arc plate is arc-shaped to adapt to the physiological curvature of the human ribs. The inner sides of the arm arc plate and the rib arc plate are also provided with silicone pads, and the connecting piece between the arm arc plate and the rib arc plate is provided with a soft pad.

[0011] Furthermore, the rib arc plate is provided with a fixing belt for fixing to the patient's ribs, the fixing belt is provided with multiple groups of adjustment buckles each with an adjustable length, the rib arc plate fits the user's ribs, the fixing belt is wrapped around the user's chest to fix the rib arc plate, and the arm arc plate fits the user's right arm.

[0012] Furthermore, ratchets are evenly provided on both sides of the inner wall of the outer cylinder, and the inner rod is correspondingly provided with a limit clamp adapted to the ratchet. The inner rod is also provided with a handle for the doctor to hold, and the handle is fixedly connected to the inner rod through a connecting rod. The outer cylinder is provided with a slot for the connecting rod to move, and the handle is provided with a control handle for controlling the engagement state of the limit clamp and the ratchet; the control handle is rotatably connected to the handle through a connecting shaft, and a spring for resetting is provided in the connecting shaft.

[0013] Furthermore, the direction of the ratchet is consistent with the direction in which the inner rod is pulled out of the outer tube, the limit clamp is provided with a slope in the direction in which the inner rod is pulled out, the ratchet is provided with a slope that matches the slope of the limit clamp, the limit clamp is provided with a vertical surface in the direction in which the inner rod is pushed, and the ratchet is provided with a vertical surface that matches the vertical surface of the limit clamp.

[0014] Furthermore, the limit clamp is slidably connected to the inner rod through a fixedly connected driving rod, the driving rod is fixedly connected to the limit plate, a spring group is provided between the limit plate and the side wall of the inner rod, one end of the driving rod is fixedly connected to the limit clamp, and the other end is provided with a transmission rack; the control handle also includes a bevel gear group, a transmission rod and a transmission gear, and the transmission gear is meshingly connected with the transmission rack.

[0015] Furthermore, the arm arc plate is also provided with an auxiliary rod, which is also provided with a connecting structure including an outer tube and an inner rod. The inner rod slides unidirectionally with the ratchet provided on the inner wall of the outer tube through a limit clamp and a control button for controlling the matching relationship between the limit clamp and the ratchet. A spring group is provided between the limit clamp and the control button, and the limit clamp is disengaged from the ratchet through the control button; the auxiliary rod also includes a connecting seat, which is fixedly connected to the back side of the arm arc plate, and the connecting seat is rotatably connected to the outer tube of the auxiliary rod. The head end of the inner rod is provided with an auxiliary handle for holding.

[0016] During the routine reduction process, it is necessary to step on the patient's armpit with your foot to resist, and use your hand to pull the patient's hand hard, while the sole of the foot pushes the humerus outward. If the entire upper arm is externally rotated at the same time, it will be easier to reduce the dislocation. By adding an auxiliary rod, this function can be achieved in a more quantitative and simple way. The ratchet under the armpit is to achieve outward push and protect the axillary nerve. The patient grabs the auxiliary handle at the distal end of the auxiliary rod with his hand, and the doctor can reduce the force when pulling the patient's arm. The auxiliary rod is provided with a ratchet in the connecting part to prevent it from retreating after traction, and the purpose of the auxiliary rod being able to rotate is to increase external rotation while the ratchet is used in one direction, making it easier to reduce. Some patients can even be reduced by only pulling and externally rotating the auxiliary rod, and the ratchet also has another function of quantitatively reducing the risk of repeated squeezing of the dislocated humerus forward and causing axillary nerve damage during normal reduction due to the doctor's lack of strength.

[0017] On the other hand, the present invention proposes that the specific steps of resetting the device include:

[0018] S1: After wearing the device, the patient first holds the auxiliary handle protrusion of the auxiliary rod, and then the doctor pulls the auxiliary rod to give the upper limb an axial traction;

[0019] S2: The doctor then uses his foot or the assistant uses a knob to control the expansion of the axillary connection to push the humerus outward;

[0020] S3: The patient grasps the auxiliary handle to achieve external rotation of the upper limb and complete the reduction operation.

[0021] The specific use is to adjust the reduction steps according to the doctor's needs, omitting S2 or S3.

[0022] Beneficial effects of the present invention:

[0023] The present invention utilizes the precise connection between the rib arc plate and the arm arc plate, and realizes the precise adjustment of the force application distance through the design of the outer tube and the slidable inner rod. The arc design of the rib arc plate and the arm arc plate fits the physiological structure of the human body, ensuring that the device can stably and accurately apply force along the anatomically optimal path during the resetting process. This design reduces the possibility of resetting failure due to different medical experiences and improves the success rate of resetting. The adjustability of the connecting parts allows real-time adjustment based on the individual differences of different patients, ensuring that the direction and intensity of the force can reach the ideal state under any circumstances.

[0024] The present invention is provided with silicone pads and soft pads on the inner side of the ribs and arm arc plates. These cushioning materials not only increase the force-bearing area, but also disperse the pressure applied to the skin surface, reducing the risk of damage to the axillary nerves. The elastic material and adjustable airbags in the soft pads can provide appropriate cushioning and adaptive adjustment during the force application process, reducing soft tissue damage and patient pain caused by excessive external force. This cushioning design provides a more comfortable and safe patient experience by optimizing the combination of material performance and human contact mechanics.

[0025] The present invention enables the inner rod to slide unidirectionally in the outer tube through the limit clamp and ratchet mechanism, thereby ensuring accurate control of the position during the force application process. This design greatly simplifies the reset operation, converts complex manual adjustments into controllable mechanical operations, and reduces the reliance on the doctor's superb skills and experience. The doctor can use the design of the foot to resist the device to further stabilize the operation, freeing both hands for more precise intervention or observation, thereby improving the overall operation efficiency and accuracy.

[0026] The design of the fixing strap and the adjustment buckle on the rib arc plate of the present invention, combined with the inflation and deflation function of the airbag in the cushion, enables the device to be individually adjusted according to the physical characteristics of different patients. This design allows the device to adapt to the physiological structure of the shoulders and chest of different patients, thereby enhancing its clinical applicability. By adjusting the fit and compression of each component in real time during use, the device can better meet the needs of different patients and ensure the stability and safety of the device during the reduction process.

[0027] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Example 2

[0046] The specific operation steps of the shoulder joint auxiliary reduction device described in this embodiment include:

[0047] After the patient was identified as having an anterior right shoulder dislocation, imaging studies were performed to confirm the type and severity of the dislocation. Based on full informed consent, the physician explained the reduction process to the patient and prepared the device.

[0048] Device preparation and adjustment:

[0049] The device is designed to be highly adjustable to suit different patient sizes. The rib arc plate 1 and the arm arc plate 2 have an arc-shaped design that fits the physiological structure of the human body, ensuring that the device fits naturally with the patient's chest and shoulders. The rib arc plate 1 is fixed to the patient's chest by a fixing belt 6 and an adjustment buckle to ensure that the device is stable and will not move during the force application process.

[0050] When adjusting the device, the doctor adjusts the length of the connecting piece through the limit clamp 303 and the ratchet 3011. The sliding of the inner rod 302 in the outer tube 301 is precisely controlled so that the angle and strength of force are just in line with the anatomical requirements of shoulder joint reduction. The modular design of the device makes these adjustments intuitive and does not require complicated operations, greatly reducing the technical threshold of the doctor. This step not only prepares an ideal path for force application, but also ensures uniform pressure distribution through adjustment, minimizing the risk of unnecessary lateral force to the patient.

[0051] Force application process:

[0052] The core of the resetting operation lies in the stability and accuracy of force application. The doctor activates the force application function of the device by applying pressure with the foot. This design allows the doctor to flexibly operate with both hands to make necessary adjustments. The silicone pad 5 and soft pad 4 equipped on the inner side of the rib arc plate 1 and the arm arc plate 2 provide a comfortable contact surface. These materials not only disperse the force and reduce the pain caused by local pressure concentration, but also increase the safety of the operation and avoid nerve damage caused by soft tissue compression. The flexibility and elasticity of the silicone pad 5 allow it to adapt to the movement of the shoulder during the force application process, further ensuring the stability of the force application and the comfort of the patient during the process.

[0053] The design of the device allows the doctor to push the arm arc plate 2 outward by applying force with the foot. This mechanism takes advantage of the natural mechanical advantages of the human body. In terms of specific structure, the outer side of the arm arc plate 2 is equipped with a silicone pad 5. The soft silicone material not only ensures comfortable contact with the patient's shoulder, but also effectively disperses pressure when the foot applies force, reducing local stress concentration. During operation, the doctor can stand or sit next to the patient, use one foot to support the silicone pad 5 on the outer side of the arm arc plate 2, and push the arc plate to move by applying uniform force outward. This method allows the doctor to quickly apply or slow down force when needed, providing a convenient and intuitive operation method. At the same time, foot force can also keep the doctor's hands flexible and free to adjust or support the patient in real time.

[0054] In addition to the foot force application, the device is also designed with the function of controlling the relative position of the inner rod 302 and the outer tube 301 by the assistant holding the handle 3021. This design provides more precise control for force application, and is particularly suitable for resetting operations that require more delicate adjustments. The assistant can adjust the position of the inner rod 302 by moving the handle 3021, thereby achieving the outward push of the arm arc plate 2. If the outward push distance is too large or the resetting operation has been completed, the assistant can press the control handle 3022 to disengage the limit clamp 303 from the ratchet 3011, so that the inner rod 302 can slide flexibly and bidirectionally in the outer tube 301. This control method mainly relies on the ratchet 3011 and the limit clamp 303 inside the device to ensure the accuracy and directionality of force application during the adjustment process. The sliding of the inner rod 302 in the outer tube 301 is precisely designed to provide a stable and continuous thrust during the force application process. This force application method coordinated by the assistant can make the force application more gentle and precise, thereby adapting to the individual differences of different patients and specific shoulder dislocation conditions.

[0055] By precisely controlling the direction and strength of the force, the shoulder joint is slowly repositioned along the ideal anatomical path. Throughout the process, the doctor needs to closely observe the patient's reaction, and each adjustment needs to be fine-tuned based on the patient's immediate feedback. Precise control reduces the need for repeated force application, which not only improves the success rate of repositioning, but also greatly reduces the risk of possible complications.

[0056] Reset confirmation and subsequent processing:

[0057] Immediately after successful reduction, radiographic confirmation is obtained to ensure that the joint has been properly reduced and that no secondary injury has occurred. At this point, the physician can evaluate the effectiveness of the device and adjust it for subsequent reduction procedures if necessary.

[0058] To ensure stability after reduction, the patient will wear a support belt to limit excessive shoulder movement and help restore the normal physiological position. At the same time, appropriate pain medication will be provided according to the patient's needs. The doctor will also develop a detailed physical therapy plan, including gradually restoring the function and strength of the shoulder joint to ensure that the patient can resume normal activities in the shortest possible time.

[0059] The beneficial effects of the precision-designed shoulder joint auxiliary reduction device combined with the actual clinical operation details have been fully verified. It performs well in optimizing the force path, improving patient comfort and reduction success rate. Its modularity and easy adjustment characteristics enable even doctors with limited experience to perform operations accurately, thus greatly improving the clinical treatment efficiency and safety of shoulder dislocation.
