Description

A traction device

Technical Field

The utility model belongs to the technical field of medical equipment, and in particular relates to a traction device.

Background Art

Fracture is a common clinical disease. The main methods of reduction after fracture are divided into manual reduction, traction reduction and surgical reduction. The traditional suspension traction method generally uses one end of a traction rope or bandage to connect to the bracket at the fracture site, and the other end is passed around the pulley to hang weights, and the traction force is controlled by manually increasing the number of weights or changing the weight of the weights. Different sizes of traction force will be used for different fracture patients, which will result in medical staff preparing a large number of weights of different weights in the process of adjusting the traction force. The workload is heavy, and the weights need to be frequently replaced according to the actual situation in the later stage, which is extremely inconvenient to use. During orthopedic surgery, it is generally necessary to use an orthopedic surgical traction device to fix the leg.

Prior art, such as the orthopedic surgical traction device proposed in the patent application number CN202120017789.7, has a leg receiving device and a leg fixing device that cooperate to solve the problems of the existing traction device being inconvenient to fix, especially in the case of emergency, and some of the inability to adjust will cause secondary injury to the patient, and some of the difficulty in adjustment will delay the effect of the operation. However, it cannot only have one force point for traction of the lower limbs, and is not very suitable for some patients with knee injuries or excessive weight. It is also not easy to install on the bed frame, and cannot match bed frames of different widths, which is not convenient for users to use.

By adopting the technical solution, the traction device can be installed on beds of different widths through the mounting frame 1. When in use, the first traction frame 2 supports the user's thigh, and the second traction frame 3 supports the user's calf, which can ensure more stable traction while minimizing the possibility of knee injury.

In this embodiment, a stabilizing member 23 is further provided on the first traction frame 2, and the stabilizing member 23 is provided between the second traction member 31 and the first traction member 22. The stabilizing member 23 further fixes the knee so that the lower limbs will not swing left and right, thereby enhancing the stability of the traction device.

In this embodiment, the first traction member 22 is provided with two groups, including a retractable first connecting rod and an adjustable length receiving belt. The two groups are convenient for the user to use the left and right lower limbs simultaneously or separately. The receiving belt supports the user's thigh, and the connecting rod is retractable and the receiving belt is adjustable in length, which is suitable for different body groups.

In this embodiment, two groups of the second traction members 31 are provided, including a retractable second connecting rod and a receiving plate with adjustable inclination. The receiving plate is provided as an arc-shaped plate, which supports the calf, expands the contact area, reduces the compressive pressure, and improves the comfort of the device.

In this embodiment, the mounting frame 1 is further provided with a support plate 11, one end of the support plate 11 is fixedly connected to the mounting frame 1, and the other end is fixedly connected to the first traction frame 2, and the end of the support plate 11 connected to the mounting frame 1 is also connected to the second traction frame 3, and the support plate 11 simultaneously supports the first traction frame 2 and the second traction frame 3 to ensure the stability of the first traction frame 2 and the second traction frame 3 relative to the mounting frame 1.

In this embodiment, the mounting frame 1 is further provided with a plurality of mounting holes 12. The mounting frame 1 is mounted on the bed through the plurality of mounting holes 12, and the installation is more stable and convenient.

In this embodiment, the length of the connecting belt is adjusted by a snap connection. The snap connection is simple and easy to operate, and it is convenient to adjust the length of the connecting belt.

In this embodiment, the stabilizing member 23 is slidably disposed on the first traction frame 2 via a slider 21 , and the stabilizing member 23 can be adjusted in height by sliding to adapt to different individual users.

Working principle and usage process:

During installation, the mounting frame 1 is installed on the bed body through multiple groups of mounting holes 12. When in use, lift the user's thigh, unfasten the receiving belt buckle, lift the user's thigh into the receiving belt, adjust the locking buckle, adjust the inclination angle of the receiving plate, place the user's calf on the arc-shaped receiving plate, adjust the height of the stabilizing member 23, and fix it on both sides of the knees to prevent the user's lower limbs from shaking left and right.

Example 2
