Traction apparatuses can be used to facilitate spinal surgery. For example, this document provides traction apparatuses that engage with the skull of a patient, traction apparatuses that engage with the pelvis of a patient, and cervical traction systems for use in conjunction with the skull and/or pelvis traction apparatuses to facilitate correction of occipito-cervical-thoracic deformities, and to safely position the head during spinal surgery. Additionally, this document provides thoraco-lumbar-pelvic spinal deformity correction apparatuses to manipulate the position of the pelvis in relation to the spine during surgery.

The present invention includes a system, kit and apparatus to aid in the realignment of one or more bones of a patient. The present invention provides a substantially rigid orthopedic stabilization scaffold for attachment of one or more external fixators for the realignment of one or more bones of a patient. The orthopedic stabilization scaffold includes a first anchorable frame and a second anchorable frame that are connectable at a point and removably attachable to an operating table.

The present disclosure relates to a universal and liquid expansion type clamping device for a pelvic fracture reduction robot. The clamping device is composed of an affected side spherical hinge support module, a pin rod clamping part, a rod-rod clamping part, a butt joint module, and a healthy side fixing module. The affected side spherical hinge support module is a main module for the pelvis clamping device, and by adopting a spherical hinge structure, the affected side spherical hinge support module is connected to the pin rod clamping part and the butt joint module respectively. The rod-rod clamping part is fixedly installed on one side of an operation table by the healthy side fixing module.

The present application provides external bone fixation systems. The systems include one or more pairs of bone fixation platforms in the form of rings or partial rings. The platforms may be coupled to corresponding bone segments. The pair of platforms are configured to accept a plurality of struts extending therebetween. The struts are configured to attach to the platforms via joints that provide three degrees of rotation. The struts are also configured such that their longitudinal length extending between the joints/platforms can be incrementally adjusted while attached to the platforms. The struts are further configured such that their total range of length adjustment can be increased by coupling at least one add-on component to the struts in situ. The lengths of each of the plurality of struts may be adjusted to arrange the platforms, and thereby the bone segment coupled thereto, in particular relative positions and orientations.

The present application discloses a needle clamping device and a leg support device. The needle clamping device includes a first component having a shaft portion; a second component hinged with the shaft portion, the second component includes a first portion and a second portion whose relative position is variable, the first portion and the second portion are arranged to clamp the shaft portion when the relative position changes; a clamping mechanism for clamping the needle, the clamping mechanism is connected to the second component, and the clamping mechanism is arranged so that at least part of the structure further clamps the first portion and the second portion, and drives the first portion and the second portion to change their relative position so that the second component clamps the shaft portion in the process of clamping the orthopaedic needle.

An automatic traction device for a lower limb fracture osteosynthesis includes a chassis structure, a lower leg supporting structure and an upper leg supporting structure connected two by two. The automatic traction device further includes a tibia distal position adjusting device, for adjusting a position and an angle of a distal end of a tibia, on the lower leg supporting structure and close to the first end portion of the lower leg supporting structure; and a tibia proximal position adjusting device, for adjusting a position and an angle of a proximal end of a tibia, on the lower leg supporting structure and close to the second end portion of the lower leg supporting structure.

Systems and methods include stabilizing a leg and providing femoral distraction during a knee arthroplasty surgery. The disclosed systems include a leg holder to receive a foot of a patient and a femoral distractor received in the leg holder and disposed underneath a knee of the patient. The femoral distractor is actuated to increase or decrease in length to distract the femur such that a surgeon may cut to resection the femur without also simultaneously providing distraction of the femur.
