Description

Technical Field

[0001] The utility model relates to the technical field of medical machinery, in particular to an adjustable traction device for postoperative rehabilitation of bone tumors. Background Art

[0002] At present, bone tumor surgery is one of the main methods for treating bone tumors. Its purpose is to remove tumor tissue through surgery to achieve the purpose of treatment. At present, the common traction methods in bone tumor postoperative rehabilitation include the following: Gravity traction: This is a simple and common traction method that uses gravity to traction the patient's bones or soft tissues. Patients can achieve this by hanging weights or using equipment such as gravity traction beds. Gravity traction is usually used for mild bone tumor postoperative rehabilitation, with limited effect, but low cost and easy operation. Continuous skin traction: This traction method applies continuous traction on the patient's skin surface and is often used to treat fractures, bone tumors, etc. It is usually achieved using instruments such as bandages, skin traction devices or external fixators, which can provide relatively continuous and uniform traction, but attention should be paid to skin protection to avoid skin damage. Intraosseous traction: This traction method directly applies traction to the bones by implanting internal fixation devices such as steel nails, screws, and steel plates in the bone. Intraosseous traction can provide strong traction and is suitable for traction that requires greater force after bone tumor surgery, but the surgical risk and complexity are high. External fixation traction: This traction method uses an external fixation device, such as an external fixator, to install on the outer surface of the patient's body to traction bones or soft tissues. External fixation traction can provide strong traction force and has good adjustability and stability. It is suitable for situations where the traction force and direction need to be precisely adjusted after bone tumor surgery. Mechanical traction: This traction method uses mechanical devices to traction the patient's limbs. Common ones include traction beds, adjustable mechanical traction devices, etc. Mechanical traction can provide more precise traction force and direction, and is suitable for situations where traction needs to be maintained for a long time after bone tumor surgery.

[0003] However, the existing traction devices currently have an inflexible adjustment mechanism design and a cumbersome adjustment process, which cannot meet the treatment needs of different patients. In addition, the traction devices in the prior art lack an effective traction direction and angle adjustment mechanism, which makes it impossible to accurately adjust the traction direction and angle during the treatment process, affecting the achievement of the treatment effect.

A gear A1401 is fixedly connected to the rotating rod A14, and the gear A1401 and the rack 1601 are meshed and connected with each other; the traction rope B11 in the utility model is installed on the traction frame 10, and a traction ring B1101 is connected to one end of the traction rope B11. The traction of the traction rope B11 in the utility model can be manually controlled by an external control handle 501, and can also be pulled by an externally arranged electric traction device (which belongs to the prior art, so the specific traction device of the traction rope B11 is not specifically shown in the figure).

[0052] The utility model is provided with an arm limiting mechanism 4 on both arm support plates 3, and the arm limiting mechanism 4 includes an arm support 401, a ratchet belt 402 and a limiting belt 403.

[0053] In the utility model, a rotating assembly is installed between the traction frame 10 and the adjusting rod 16, and the rotating assembly includes a gear housing 17, a gear B20 and a turntable 21. The gear housing 17 is fixedly connected to the top of the adjusting rod 16, and the turntable 21 is fixedly connected to the bottom of the traction frame 10. The gear B20 is arranged inside the gear housing 17, and the gear B20 is fixedly connected to the bottom of the turntable 21. A rotating rod B19 is rotatably connected inside the gear housing 17, and a hand wheel B18 is fixedly connected to one end of the rotating rod B19.

The user can adjust the speed or direction of the motor through the control button 24, thereby controlling the movement of the clamping roller. For example, increasing the operation of the control button 24 can increase the output power of the motor, so that the clamping roller 25 generates a greater clamping force, thereby increasing the traction force of the traction rope B11. The clamping roller 25 is driven and connected to the controller 23, and the clamping roller 25 can be driven to rotate by the controller 23. When the traction rope B11 needs to maintain a certain traction force after the traction rope B11 is adjusted, the traction rope B11 can be clamped by the clamping roller 25 to maintain the traction state of the traction rope B11.

[0055] Working principle: When the utility model is in use, the patient lies flat on the mattress 101. The patient who needs arm traction therapy places both arms or one arm on the arm support plate 3. The arm limiting mechanism 4 can be adjusted according to the size of the patient's arm to fix the position of the arm to ensure stable support of the arm. Then the traction ring A507 is put on the patient's wrist. The staff controls the winding shaft 503 to rotate at the same time by controlling the handle 501, thereby adjusting the tension of the traction rope A505 to achieve traction therapy for the patient's arm. The patient who needs leg traction therapy lies on his back or prone on the mattress 101, and the staff puts the traction ring B1101 on the patient's ankle. The staff can rotate the rotating rod B19 through the hand wheel B18 to adjust the rotation angle of the traction frame 10 relative to the adjusting rod 16, thereby changing the direction and angle of traction to meet different treatment needs. The traction of the traction rope B11 can be manually controlled by the external control handle 501, or it can be pulled by an externally arranged electric traction device. When the traction rope B11 needs to maintain a certain traction force after adjusting it, the traction rope B11 can be clamped by the clamping roller 25 on the controller 23 to maintain the traction state of the traction rope B11 to ensure that the treatment effect continues. After the treatment is over, the traction ring A507 and the traction ring B1101 can be directly untied to complete the rehabilitation treatment process.
