Embodiment Construction

[0019] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] The overall structure of the present invention is as Figure 1 to Figure 4 shown.

[0021] Such as figure 1 , the series-parallel long bone reduction robot consists of a series part and a parallel part. The two are connected or split; when connecting the series part and the parallel part, the fixed plate 2 and the fixed plate 7 of the series part are respectively placed on the proximal platform connecting plate 19 and the far-end platform connecting plate 16, and then the proximal platform The pressing plate 20 and the far-end platform pressing plate 17 are respectively fixed on the proximal platform connecting plate 19 and the distal platform connecting plate 16 by bolts or other means, and can connect the series part and the parallel part. Take the opposite steps when splitting the two. Pass the positioning rod 1 through the fixin...

Abstract

The invention discloses a long bone resetting robot in series-parallel connection, which comprises a serial connection part and a parallel connection part, wherein the serial connection part comprises a near-end fixing mechanism and a far-end fixing mechanism which are connected or disconnected through a positioning rod; each of the near-end fixing mechanism and the far-end fixing mechanism comprises a fixing plate, a locking bolt, a connecting rod, a connecting rod mounting base, a bracket rod and a latch clamping mechanism; the latch clamping mechanism comprises a connecting bolt and a latch; the parallel connection part comprises a far-end platform panel, a far-end platform connecting plate, a far-end platform pressing plate, a near-end platform panel, a near-end platform connecting plate, a near-end platform pressing plate and a stretching rod mechanism; and the stretching rod mechanism comprises a connecting hinge, a sleeve and a connecting rod. The long bone resetting robot in series-parallel connection is mainly used for realizing a function of assisting the resetting of long bone fracture by the robot under a closed condition. The long bone resetting robot in series-parallel connection has the characteristics of flexible mechanism, large work space, convenience in operation, and the like, and has an excellent application prospect.

Description

technical field [0001] The invention relates to a series-parallel long bone reset robot, which belongs to the technical field of surgical medical instruments. Background technique [0002] Traditional reset methods mainly rely on the experience and skills of doctors. The operation time is long, the work intensity of medical staff is high, the reset accuracy is not easy to guarantee, and problems such as poor reset are prone to occur. Common closed reduction, percutaneous or small incision fixation methods require intraoperative X-ray image perspective positioning, and doctors and patients are easily exposed to radiation. Open reduction is easy to damage the blood supply and soft tissue around the fracture, causing more bleeding and easy infection, which is an important reason for fracture nonunion. These problems can be effectively solved by using robot-assisted reset. In the current study, Gramham A.E. abroad disclosed a femoral shaft fracture reduction system in the docu...
