Problems solved by technology
[0003] However, in hip arthroplasty, for the direct anterior approach, because the patient’s proximal femur is difficult to expose, intraoperative manipulation may easily cause the patient’s medullary cavity to contusion or the prosthesis to penetrate the cortical bone, causing medical hazards

Embodiment Construction
[0045] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, so as to understand the essence of the present invention more clearly and intuitively.
[0046] combine figure 1 , figure 2 and image 3 shown;
[0047] A device for elevating the proximal femur in direct anterior approach hip arthroplasty provided by the present invention includes a holding member 10 for holding up the proximal femur and driving the holding member 10 up and down The lifting device 20, the main controller 30 for controlling the lifting device 20 and the fixing seat 40 for fixing the lifting device 20;
[0048] Wherein, the lifting member 10 is fixed on the lifting device 20 , the lifting device 20 is fixed on the fixing base 40 , and the lifting device 20 is connected to the main controller 30 by signals.
[0049] Based on the above, it is clear that a device for elevating the proximal femur in th...

The invention discloses a device for lifting the proximal femur in the direct anterior approach hip joint replacement. The device comprises a supporting part used for supporting the proximal femur, alifting device used for driving the supporting part to rise and fall, a main controller used for controlling the lifting device, and a fixing base used for fixing the lifting device, wherein the supporting part is fixedly arranged on the lifting device, the lifting device is fixed to the fixing base, and the lifting device is in signal connection with the main controller. The device has the beneficial effects that through the control of the main controller, the lifting device can drive the supporting part to rise or fall to the needed height for lifting the proximal femur of a patient, so thatthe lifting and exposing of the proximal femur of the patient are facilitated, a doctor can conveniently carry out the hip joint replacement on the patient later, the potential medical treatment hazards including that a medullary space file or a prosthesis penetrates through the cortex of bone and the like caused to the patient after the surgery are avoided, and further, the device is strong in practicability and good in use effect.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to a device for elevating the proximal end of the femur in direct anterior approach hip arthroplasty. Background technique [0002] In the prior art, there are surgical approaches such as direct anterior approach, anterolateral approach, and posterolateral approach for patients undergoing hip replacement. As for the direct anterior approach, as a truly minimally invasive approach, it has obvious advantages in low dislocation rate, good gait, and quick recovery, so it is preferred to be used by doctors during surgery. [0003] However, in hip arthroplasty, for the direct anterior approach, since the patient's proximal femur is difficult to expose, the intraoperative operation may easily cause the patient's medullary cavity to contusion or the prosthesis to penetrate the cortical bone, causing medical risks. [0004] Based on this, aiming at the current situation, a device ...
