Description

Lower leg fracture sterile aseptic lifting device

technical field

The utility model relates to the field of orthopedic surgical appliances, in particular to a sterilized and aseptic lifting device for calf fractures.

Background technique

At present, the tibia and fibula are the most frequently fractured parts of long tubular bones, accounting for about 8%-10% of systemic fractures. Traffic injuries are the most common, while falls are less common and the most serious injuries occur in traffic injuries.

The tibia and fibula are often prone to simultaneous tibiofibular fractures under violent action, and are combined with severe calf soft tissue damage. At present, the disinfection of the lower limbs is mainly carried out by the doctor's manual lifting of the lower limbs. Manual lifting of the feet has obvious shortcomings. Human strength is limited. As time goes by, fatigue will gradually appear, and it is difficult to maintain proper treatment of patients. For severe comminuted fractures of the tibial and fibula, it is necessary for the assistant to pull and lift effectively at the same time, which will be a great test for the assistant. If you cannot maintain a good posture, you will Contaminated wounds, in severe cases, will cause damage to the blood vessels and nerves of the patient's lower legs, and the probability of lower extremity compartment syndrome will also increase.

Therefore, it is an important direction that many clinical orthopedic surgeons have been exploring, which can not only reduce the workload of medical staff, but also reduce the injury of patients. In 2013, domestic doctors such as Wen Yayuan invented a "lower limb disinfection supporter", patent number "201310389871.3", which uses slide rails and two jacks to replace artificial leg lifting; Hak from the Geisinger Medical Center of Colorado State University in the United States In the JOT magazine in July 2013, Professor et al. introduced the method of hanging the lower limbs by hanging from the roof. The method can be applied to disinfection of the lower limbs of patients with no trauma or normal lower limb force lines. However, for severe multiple fractures of the lower leg, how to effectively maintain the line of force and complete disinfection for a long time has become a prominent clinical problem in reducing iatrogenic injuries.

Therefore, the fracture of the backbone after the fracture, some of which are multiple fractures, when the fracture is lifted during disinfection, it is easy to cause secondary damage to the leg.

Facing the problems of many patients with lower limb injuries, relative shortage of surgeons who are prone to fatigue, and difficult to maintain the posture of lower limb surgery disinfection, the utility model of a safe and effective lower limb disinfection tool has become the common wish of the majority of hand orthopedic surgeons. .

Utility model content

The utility model aims to solve the above-mentioned problems in the prior art, and provides a sterilized and aseptic lifting device for calf fractures, which stretches the leg muscles, lifts the legs in a balanced manner, and reduces secondary damage to the legs.

The utility model adopts the technical scheme to solve the technical problem: the sterilized and aseptic lifting device for calf fractures includes a base on which a support frame is fixed, and a thigh fixing mechanism for fixing the root of the thigh is installed on the support frame. The ankle stretching mechanism for external stretching and the lifting mechanism for supporting the feet, the top of the support frame is fixed with a horizontal support rod, the thigh fixing mechanism is installed at the inner end of the horizontal support rod, and the ankle stretching mechanism is installed on the support frame. The lifting mechanism is distributed on the horizontal support rod; the thigh fixing mechanism includes a lifting rod slidingly installed on the inner end of the horizontal supporting rod. The lower end of the lifting rod is rotatably connected with a rotating rod. The lower end is equipped with a fixed ferrule; the lifting mechanism includes a chute arranged on the lateral support rod, a set of sliding wheels are installed in the chute, and positioning screws are installed on the sliding wheels, and the lower end of the sliding wheel is hung with a suspension ring. , a pair of suspension frames are connected to the suspension ring; the ankle stretching mechanism includes a sliding sleeve arranged on the support frame and sliding up and down, fastening screws are installed on the sliding sleeve, and a rotating head is installed on the side of the sliding sleeve, and the opening on the rotating head There is a mounting hole, a sliding rod is installed in the mounting hole, and a positioning bolt for positioning the sliding rod is installed on the rotating head. The inner end of the sliding rod is fixed with a support plate. The support surface of the support plate is horizontally concave. A side plate is fixed on the side, and a fixing ring for fixing the patient's ankle is installed at the end of the support plate.

This is mainly for the disinfection before the fracture operation. First, fix the thigh root, and then put the fractured leg on the hanger and the support plate. The fixing ring is fixed on the patient's ankle, and then the leg is stretched outward by sliding the rod to keep the leg in a stretched state, avoiding the extrusion of the backbone and muscles, and expanding the skin of the leg, which is convenient for disinfection. After each pass, replace the hanger and support the new hanger on the area that has been disinfected, so as to achieve comprehensive disinfection without causing leg damage.

In order to be further improved, a sleeve is connected to the inner end of the sliding rod, and a spring connected to the sliding rod is installed in the sleeve, and the fixing ring is fixed on the sleeve. In this way, the sliding pull rod has a certain elastic space when pulling the legs, so as to avoid straining the legs.

Further improvement, the support frame is provided with a positioning slider, which cooperates with the side of the hospital bed, and the side of the hospital bed is provided with a bar-shaped groove, and the positioning slider is snapped into the bar-shaped groove and is slidably matched with it. This moves the position of the support bracket.

Further improvement, a vertical plate is installed on the support plate, the lower end of the vertical plate is rotated and installed on the support plate, a buckle on the toe is installed on the inner side of the upper end of the vertical plate, and a hook for pulling the vertical plate outward is connected to the outer side of the upper end of the vertical plate. Elastic drawcord. This cooperates with the fixing of the retaining ring, which fixes the toe part and pulls the toe outward to prevent the toe from hooking up.

The beneficial effects of the utility model are: the utility model provides a disinfection auxiliary device for patients with severe fractures, fixes and lifts the fractured legs, and at the same time straightens the legs, fully disinfects the legs, and fixes and supports the legs in place , to avoid secondary injury, and straighten the legs, not only reduce the workload of medical staff, but also facilitate the operation on the legs, which is conducive to widespread promotion.
