Abstract

The utility model relates to a half round type bone-connecting device, comprising an upper half ring and a lower half ring with an inner ring gear. The upper half ring is connected with the lower half ring by three elevating screws used for adjusting a space between the upper half ring and the lower half ring, the upper half ring is provided with two bone needle adjusting stands, a big universal joint bone needle stand is connected with the lower half ring inner gear, and a bone needle horizontal-shift device is arranged on a needle-arranging nut of the bone needle adjusting stand of the upper half ring. The utility model can little adjust limb position, can enhance bone-connecting accuracy rate, and can penetrate bone needle from any direction. The utility model has the advantages that patients' pain is small and doctors can avoid damage from X-ray, and is suitable for connecting bone at each position of breaking limbs on human body limbs.

Description

Novel semicircular multifunctional bone fracture device

This utility model is a kind of device that is used to draw with the reseting fracture limbs.

Traditional synthetism mode such as surgical operation steel plate, steel nail bone internal fixation, clamping plate skin external fixation, Gypsum Fibrosum skin external fixation traction treatment etc., what have wants second operation, skin external fixation traction treatment etc., what have wants second operation, it is not firm that skin external fixation mode exists the severed limb location, disadvantages such as easy infection make the patient stand the misery that bring the return location again in the treatment, also make the doctor repeatedly be subjected to the infringement of X ray to health, for overcoming these deficiencies, people have invented bone fracture device, are 96222616.5 " semicircular multifunctional bone fracture device " as application number, and it has overcome the defective of traditional synthetism apparatus and synthetism mode, the whole bone in extremity fracture position is fixed once to be finished, the synthetism operating time is short, damages for a short time, and the patient suffering is little, but human limb is not straight, thereby existing bone fracture device also to exist the spicule direction of threading a needle single, can not adapt to limbs naturalness, severed limb reset be difficult for fine setting and spicule can not before and after the deficiency of translation.

The purpose of this utility model is, a kind of spicule of can in any direction wearing is provided, the severed limb fine-tuning novel semicircular multifunctional bone fracture device that resets.

Following mode can realize this utility model:

A kind of novel semicircular multifunctional bone fracture device, comprise following semi-ring, worm screw and an internal ring gears engaged that goes up semi-ring and have the internal ring gear, but the adjustment of left rotation and right rotation three elevating screws of semi-ring spacing up and down connects upward semi-ring and following semi-ring, establish two spicule adjustment racks on the last semi-ring, a big universal joint spicule frame also is set is connected with following semi-ring inner circular tooth wheel.

Can adjust the spicule translation device that spicule moves forward and backward is installed on the dress pin nut of a spicule adjustment rack of semi-ring.

Last semi-ring middle inside is equipped with the triaxial spicule frame.

The big universal joint spicule of this utility model frame is taken turns the severed limb synthetism that combines and be applicable to each position of extremity with following semi-ring inner circular tooth, the spicule translation device can make the once correctly butt joint of disconnected stubble with the shift unit that can finely tune the severed limb position, and can in any direction wear spicule, the whole accurate speed of bone is fast, and the patient suffering is little, fixes after resetting, this semi-circular bone fracture device is fixedly after the severed limb, still leave the space, do not influence and suffer from the limb blood circulation, the healing of order fracture limbs is fast.
