Nest joint is connected in outer fix bar by the internal thread of outer sleeve, treats that threaded rod is connected to ilium on the bulb of multi-directional ball
External fixing rack and femur external fixing rack；The femur external fixing rack includes external fixing rack, and the external fixing rack is outer fixed for straight trip
Bar, near-end is provided with screw thread, connects the lower end of universal hip joint mobilizer.
It is used as further scheme of the invention：Pressurization locking knob is provided with the universal cup-and-ball joint, can be universal
Activity, reaches the various angles needed for movable hip joint, and locking knob is tightened after angle needed for being adjusted to.
It is used as further scheme of the invention：The outer fixation fixed for femur is provided with the femur external fixing rack
Pin, and be fixed on by outer geometrical clamp on femur external fixing rack.
It is used as further scheme of the invention：It is solid outside the ilium external fixing rack, universal hip joint mobilizer and femur
The main body for determining frame is made by aluminum alloy material.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention provides and adjustable shelf is fixed outside a kind of modular hip prosthesis, and structure is novel；The present invention is used for the pressure for mitigating hip joint
The fixed angle of power, as needed dynamic adjustment hip joint.The invention can make patient's hip strut or pressurize, as needed adjustment
Hip joint pressure, can dynamically adjust the fixed angle of hip joint.Be association of activity and inertia it is universal adjustment hip joint fixed angle and work
Dynamic angle；The needle rod holder fixed form that the connection of external fixing rack and sclerotin is commonly used using current orthopaedics；This kind of external fixing rack structure
Simply, install, it is easy to operate.
