Description

Traction reduction appliance for lower limb fracture

Technical Field

The utility model belongs to the technical field of medical instrument, a low limbs fracture pulls utensil that resets is related to.

Background

In the operation of lower limb fracture treatment, the traction operation is a basic and also very important operation, the effect of which directly affects the surgical result and the recovery after the operation. In the current fracture surgery treatment, the traction operation is mostly completed by doctors with reference to preoperative or intraoperative perspective images by experience and freehand, the operation is not only complicated but also depends on the clinical experience of the doctors, and meanwhile, the doctors often need to be directly exposed to X-rays for operation, so that the radiation dose of the doctors is increased.

At present, in operations such as tibial fracture reduction, knee joint replacement and the like, a doctor is often required to hold a diseased limb with two hands to keep the diseased limb at a knee bending position, so that a large amount of physical strength of the doctor is consumed, the stability of the diseased limb in the operation cannot be ensured due to the instability of force application of the hand, and the operation effect is difficult to ensure.

At present, some traction beds are also available, which can rotate inside and outside to adjust the fracture position to reach the position required by doctors, but the volume and the weight of the traction bed are large, high-temperature sterilization and disinfection cannot be realized, and the affected limb is suspended by slight traction in the use process, the large leg and the small leg are kept on the same straight line, and the knee joint cannot be bent, so that the traction bed cannot be used in the fracture operation of the tibia basically, the price of the traction bed is high, and the configuration of each hospital is limited. And the traction bracket is partially used, but the traction bracket for the tibial fracture operation at present has various structures, does not form a unified product, has incomplete functions and can not meet the use requirements.

Through retrieval, the utility model patent with the Chinese patent grant publication number of CN207220997U and the grant publication date of 20180413 discloses a traction reduction device, which comprises a bracket for keeping the knee bending position of an affected limb, wherein the bracket comprises a main panel, a support plate and a self-locking structure; the self-locking structure is used for hinging the top end of the main panel and the top end of the supporting plate, and an adjustable supporting angle used for supporting the knee bending position of a patient is formed between the plane of the main panel and the plane of the supporting plate in a hinging manner; the main panel is provided with a traction resetting module; the supporting plate is used for supporting the main panel; the main panel realizes the support of the affected limb and the fixation of the traction reduction module. The disadvantages are that: the traction resetting module is used for limiting the traction angle of the traction assembly; the support plate and the main panel are relatively narrow in size and easy to topple over after standing up; the adjustment mode is troublesome, the adjustment range is large and unstable, and the affected limb is easily injured.
