specific Embodiment approach 1

[0011] Specific implementation mode one: combine figure 1 This embodiment is described. A half-ring restoration device for long bone fractures of limbs in this embodiment includes a slidable base and a half-ring restoration assembly. The half-ring restoration assembly is arranged on the slidable base. The slidable base includes a first Fixed slider 1, second fixed slider 2, moving slider 3 and two sliders 4, the half-ring restoration assembly includes two upper sliders 5, two lower sliders 6 and two sets of bone needles for lifting The shifter 7, the first fixed slider 1 and the second fixed slider 2 are arranged sequentially from left to right, and two sliders 4 are arranged side by side between the first fixed slider 1 and the second fixed slider 2, and the moving The slider 3 is slidably installed on the two sliders 4 between the first fixed slider 1 and the second fixed slider 2, and the half-ring restoration assembly also includes two semi-annular rotating rings 8 and a s...

specific Embodiment approach 2

[0012] Specific implementation mode two: combination figure 1 Describe this embodiment, each semi-annular rotating ring 8 of this embodiment all comprises worm screw 11, half-ring fixing frame 12 and turbine 13, and half-ring fixing frame 12 is arranged on the first fixed slider 1 or moving slider 3, A worm 11 is provided at the bottom of the half-ring fixing frame 12, and a worm gear 13 is arranged on the inner wall of the half-ring fixing frame 12, and the worm gear 13 and the worm screw 11 are engaged with each other. Such setting facilitates the flexible swing of the semi-circular rotating ring 8 during use. Other compositions and connections are the same as in the first embodiment.

[0013] When this embodiment is in use, the operation process is carried out by a doctor. Turn the other end of the screw rod 9 to rotate the handle to move the position on the slider 3, and insert the worm 11 through the rotating shaft or a wrench. In the needle shifter control hole 19, the...

specific Embodiment approach 3

[0014] Specific implementation mode three: combination figure 1 The present embodiment will be described, and the turbine 13 of the present embodiment is a semi-annular turbine. Such setting is convenient for the patient to place the affected part, and at the same time facilitates the mutual cooperation with the worm 11 to swing. Other compositions and connections are the same as those in the second embodiment.

Abstract

The invention discloses a limb long bone fracture semicircular reduction device, and relates to a fracture reduction device. The reduction device aims at solving the problem that the existing close reduction fracture external fixing stand is inconvenient for traumatic fracture and open fracture. A first fixing slide block and a second fixing slide block of the reduction device are arranged from left to right sequentially; two slide rods are arranged between the first fixing slide block and the second fixing slide block; a movable slide block is slidingly arranged on the two slide rods and between the first fixing slide block and the second fixing slide block; two semicircular rotary rings are arranged on the first fixing slide block and the movable slide block respectively; two spicule angle adjustment seats are arranged on the outer side of each of the two semicircular rotary rings; two movable spicule lifting shifters are arranged on two upper slide rods; one end of a lower screw penetrates through the second fixing slide block to be connected with the movable slide block; and a rotary handle is suspended at the other end of the screw. The reduction device is used for fracture reduction.

Description

technical field [0001] The invention relates to a fracture restoration device, in particular to a half-ring restoration device for long bone fractures of extremities, which belongs to the field of medical instruments. Background technique [0002] Fracture reduction, fixation, and functional training are the three major principles of fracture treatment, as well as the basic principles of rehabilitation therapy. Clinically, fracture reduction is divided into anatomical reduction and functional reduction, and the reduction methods are divided into manual reduction and open reduction. Two, functional training is the main means of rehabilitation after fractures, and patients should be encouraged to perform functional training early to promote fracture healing and prevent or reduce the occurrence of sequelae and complications. In recent years, with the rapid development of medical devices, functional reduction is usually used for fracture restoration. The Chinese patent publicati...
