Problems solved by technology
[0004] Although the effect is good when the Brownian frame is used for the treatment of such fractures, there are many problems at the same time. One is that the overall structure of the Brownian frame is relatively large. The object is in the form of weights, and in order to obtain more accurate traction, there are various types of weights, which makes storage and retrieval very troublesome, and the safety factor is not high when used, and it is easy to hurt medical staff
Moreover, even if a variety of weights are used, it is difficult to make the traction force accurate and affect the therapeutic effect

Embodiment Construction
[0032] The present invention will be further described below in conjunction with drawings and embodiments.
[0033] refer to Figure 1 to Figure 9 , an integrated bone retractor, including a telescopic rod 4 and a clamping part 2 and a pulley 5 respectively arranged at both ends of the telescopic rod 4, the clamping part 2 is used for clamping on a hospital bed, and the pulley 5 is used for wearing multiple Leash. A base 1 is also provided between the clamping part 2 and the telescopic rod 4, and the telescopic rod 4 is rotatably plugged into the base 1, and the base 1 is also opened for placing The accommodating groove 14 of the telescopic rod 4 is also provided with a force adjuster 6 on the telescopic rod 4 . It is worth noting that the strength regulator here can be purchased from the market, that is, it can generate a specific pulling force on the traction rope. For example, in this embodiment, a commercially available fishing reel is used, which includes a shell 61, an...

The invention relates to the technical field of orthopedics medical instruments, and particularly provides an integrated bone tractor. The integrated bone tractor comprises a telescopic rod (4), a clamping connection portion (2) and a pulley (5), wherein the clamping connection portion (2) and the pulley (5) are arranged at the two ends of the telescopic rod (4) respectively. A base (1) is furtherarranged between the clamping connection portion (2) and the telescopic rod (4). The telescopic rod (4) is rotationally connected to the base (1) in an inserted manner. A containing groove (14) for containing the telescopic rod (4) is further formed in the base (1). A force regulator (6) is further arranged on the telescopic rod (4). The integrated bone tractor has the beneficial effects that a traditional Brown's bracket and weight traction are abandoned, and transferring and usage are more convenient to carry out; and at the same time, the integrated bone tractor is suitable for fracture treatment of children as well, and the medical cost is reduced.
Description
technical field [0001] The invention relates to an orthopedic medical device, in particular to an integrated bone tractor. Background technique [0002] When the patient's femur is fractured, it is often necessary to use a bone distractor for treatment. At present, the bone distractor in the prior art refers to figure 1 , including the traction arch a and the Kirschner wire c, the traction arch a is provided with a pull ring b, when the bone distractor is used for treatment, it is often necessary to use a Brownian frame for assistance. The existing treatment process is as follows: insert the Kirschner wire c into the traction arch a, drive the Kirschner wire c into the bone, and pass the traction wire through the pull ring b for traction. And the use method of Brown's frame is to place patient's lower limbs on the Brown's frame and use traction rope to connect weight to pull ring b by traction pulley to reach the purpose of treatment. [0003] For the treatment of children...
