Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a bone traction device. Background Art

[0002] A skeletal traction device is a medical device used to traction and fix the skeletal system to treat fractures, spinal problems, joint dislocations, etc. The purpose of a skeletal traction device is to change the position of bones or joints by applying traction force, promote fracture healing, correct spinal deformities, and reduce joint dislocations. The use of a skeletal traction device needs to be carried out under the guidance of a doctor, who will develop a corresponding treatment plan based on the patient's condition and needs, and monitor and adjust the size and direction of the traction force.

[0003] The traction of existing skeletal traction devices usually requires the use of counterweights to provide constant traction. The role of the counterweight is to balance the traction force applied to the body by applying gravity to maintain a stable traction state. When using a skeletal traction device, the doctor will determine the required traction force based on the patient's specific situation and needs and select the appropriate counterweight. Counterweights are usually achieved by adding metal or heavy objects to the traction device. The specific counterweight method and weight depend on different traction devices and treatment needs. Some devices may be equipped with fixed counterweights, while other devices may require manual adjustment of the number and position of counterweights.

[0004] However, this type of weight design may not be easy to adjust, and the weight needs to be added or removed manually. This may require frequent operation and adjustment, increasing the workload of medical staff, and may cause inconvenience and discomfort. If the weight is not properly fixed or adjusted, there may be safety hazards. Unstable weights may cause the traction device to fall off or the traction force to increase suddenly, causing discomfort or injury to the patient. Utility Model Content

[0025] Specifically, when using the traction therapy device, the patient can place his legs on the main support 1. The main support 1 is made of solid metal material and is covered with a soft gasket 13 on the surface to ensure the patient's comfort. Then, the restraint belt 9 firmly fixes the legs on the main support 1 to prevent movement during the traction process, thereby ensuring the safety and effectiveness of the treatment. Subsequently, the patient drives the threaded column 16 to rotate through the handle 15. During this process, the threaded column 16 will push the splint 17 to move toward the patient's leg and gradually clamp the traction position. When the splint 17 clamps the patient's traction position, the motor 4 starts to drive the winch 5 to rotate. The rotation of the winch 5 will gradually retract the tension rope 6, and then pull the traction frame 8 to pull the patient. During the process of tightening the tension rope 6, the tension sensor 7 will monitor the magnitude of the tension in real time. When the tension reaches the preset value, the tension sensor 7 will send a signal to the motor 4 to stop rotating, thereby ensuring the safety and effectiveness of the traction therapy.

[0029] Specifically, first, when the device needs to be fixed in a specific position, the threaded column 2 19 can be driven to slide out from the inside of the cross bar 12 by rotating the control handle 3 24. As the threaded column 2 19 slides out, the clamp 1 20 will extend to the foot of the bed. Next, the foot of the bed can be clamped by rotating the clamp 21. The design of the clamp 21 enables it to fit closely to the foot of the bed, thereby ensuring the stability between the device and the foot of the bed. At this time, the foot of the bed has been firmly clamped by the clamp 1 20 and the clamp 2 21.

In addition, the device also has a certain versatility. Since the design of the clamp block one 20 and the clamp block two 21 has a certain adjustability, it can adapt to bed legs of different sizes and shapes, so that the device can be widely used in different scenarios to meet the diverse needs of users.

[0030] Working principle: When traction is performed on the patient, the legs can be placed on the main support 1, and then the legs are bound by the restraint belt 9 and fixed by the Velcro 10.
