Dislocation detecting system in hip joint replacement

Abstract

The invention provides a dislocation detecting system in hip joint replacement. The dislocation detecting system in the hip joint replacement comprises a bulb implant, and a light ray detecting module, a transmitting module, a processing module and a reminding module which are successively connected. The bulb implant comprises a base and a transparent hemispheric cover installed on the base. The light ray detecting module comprises an emitting device and a receiving device. The light ray emitted by the emitting device is pointed to the artificial acetabulum. The receiving device is used for receiving the light ray emitted by the emitting device. The light ray detecting module is used for generating light ray detection information, and sending the light ray detection information to the processing module through the transmitting module. The processing module is used for receiving the light ray detection information, and determining whether the bulb implant is dislocated according to thelight ray detection information; and while the bulb implant is dislocated, sending reminding information to the reminding module, and enabling the reminding module to remind. So the dislocation detecting system in the hip joint replacement is capable of assisting a doctor to discover the dislocation phenomenon in the hip joint replacement timely and intuitively, reducing the surgery difficulty, and improving the surgery success rate and the curative effect.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a dislocation detection system for hip joint replacement. Background technique [0002] Hip joint replacement, also known as artificial hip replacement, is to fix the artificial prosthesis, including the femoral part and the acetabular part, on the normal bone with bone cement and screws to replace the diseased joint and reconstruct the normal state of the patient's hip joint. It is a relatively mature and reliable treatment method. [0003] Due to the physiological structural characteristics of the hip joint, the outer side of the femoral head is covered by a thick layer of fat and muscle. In total hip replacement, there is a certain angle requirement for the installation of the ball head prosthesis. Therefore, after the installation is completed, the prosthesis trial Finally, the doctor needs to move the patient's hip in a wide range to know whether the size and positi...

Problems solved by technology

As a result, there is a problem that, because the position of the ball head prosthesis in the acetabulum cannot be intuitively understood, when the ball head prosthesis is partially or completely detached from the acetabulum, the doctor cannot do it first. It takes time to discover the dislocation problem, which increases the difficulty of the operation and reduces the success rate and curative effect of the operation
