Embodiment 1

[0031] Embodiment one: if figure 1 , 2 , 3, the present embodiment includes a ground support structure 1, and the support assembly for one side of the affected leg is installed on the ground support structure 1. The support assembly can be one set or two sets, depending on the patient's injury situation. The support assembly includes a thigh support 21 erected on the ground support structure 1, and a thigh support 211 for placing the thighs is also erected on the thigh support 21; a thigh support unit 22 is also installed between the thigh support 21 and the ground support structure 1 , the thigh support unit 22 is used to support the thigh support 21 . A calf support 31 is also erected on the ground support structure 1, and a calf support 311 for placing the calf is also erected on the calf support, and a hydraulic cylinder 32 is also installed between the calf support 31 and the ground support structure 1, and the hydraulic cylinder 32 is used for It supports the lower leg...

Embodiment 2

[0037] Embodiment two: if Figure 4 , 5 As shown, the difference from Embodiment 1 is that the top of the thigh bracket 211 and the bracket rod 212 are connected by a secondary universal joint 91, and a buffer limit unit 6 is also provided between the thigh bracket 211 and the bracket rod 212, The buffer limit unit 6 includes: an upper annular guide groove 92 set at the bottom of the thigh bracket 211 and centered on the auxiliary universal joint 91; The upper block 93 of sliding fit; the lower annular guide groove 94 provided on the side wall of the bracket rod 212 and arranged axially around the bracket rod 212; clamped in the lower annular guide groove 94 and connected with the lower annular guide groove 94 is a lower block 95 that slides and fits; the arc-shaped sleeve 61 and the arc-shaped rod 62 that are socketed and matched with each other, the arc-shaped sleeve 61 and the arc-shaped rod 62 are all arc tubes centered on the auxiliary universal joint 91 be placed in th...

Embodiment 3

[0038] Embodiment three: as Image 6 As shown, the difference from Embodiment 1 is that the lifting support unit is a hydraulic cylinder 32b, and one axial end (piston rod end) of the hydraulic cylinder 32b is hingedly matched with the bottom of the calf support 31, and the other axial end (cylinder body) of the hydraulic cylinder 32b is end) is hingedly fitted with the ground support structure 1. The effect of the hydraulic cylinder 32b is not only to realize the lifting of the calf support 31, but also to support the calf support 31, and cooperate with the calf support 31 to play a supporting role when it is connected with the universal joint part 4, so as to ensure the stability of the calf support 31 during work. Of course, the hydraulic cylinder 32b can also be replaced by telescopic elements with axial functions such as telescopic rods or cylinders, and these devices all have a locking function after axial telescopic expansion. In addition, the number of hydraulic cylin...

Abstract

The invention discloses an auxiliary device of a combined lower limb orthopedic operation traction bed. The auxiliary device comprises a ground supporting structure. A supporting component is mounted on the ground supporting structure and comprises a thigh support, a shank support, a universal joint member used for connecting the thigh support with the shank support, a thigh bracket set up on the thigh support, a shank bracket set up on the shank support, a thigh supporting unit for supporting the thigh support, and an ascending-descending supporting unit used for driving the shank support to ascend and descend and supporting the shank support to swing around the universal joint member, wherein an operating space which is not connected is formed between the shank bracket and the thigh bracket. The auxiliary device has the advantages that for a patient with femoral neck fracture, the fractured side can be fully and stably abutted when being placed, so that physical strength consumption and nervousness of the patient are reduced; physical strength of an operator can be saved with the help of an operation support, the femoral neck fracture can be positioned conveniently, and accuracy of embedding insertion removing is improved greatly.

Description

technical field [0001] The invention relates to the field of orthopedic surgery, in particular to a hybrid auxiliary device for lower limb orthopedic surgery traction bed. Background technique [0002] Displaced femoral neck fracture is one of the difficulties in trauma orthopedic treatment. For displaced femoral neck fractures, closed reduction and internal fixation is the main treatment. For severe displaced fractures, when closed reduction is not ideal, open reduction and internal fixation can be considered, and the surgical incision can be selected through the anterior approach of the hip joint (Smith- Peterson incision) or lateral hip approach (Watson-Jones incision); for elderly patients with femoral neck fractures, hip replacement techniques can also be considered, but in general, closed reduction and internal Mainly fixation. The method of internal fixation is currently based on multiple (usually 3) parallel hollow threaded screws. The threaded screws are passed th...
