Joint positioning guide plate based on medical image

Abstract

The invention relates to the technical field of medical devices, specifically a joint positioning guide plate based on medical images, including a positioning guide plate body. The structure of the present invention is provided with three sets of elastic connectors of the same structure at the lower end of the arc-shaped plate, the first elastic connector, The second elastic connector and the third elastic connector fix the positioning guide plate on the lower end surface of the arc-shaped plate, the first elastic plate on the elastic connector is fixedly connected with the lower end surface of the arc-shaped plate, and the second elastic connector on the elastic connector The plate is fixedly connected to the upper end surface of the positioning guide plate, and the elasticity of the first elastic plate and the second elastic plate itself, as well as the springs arranged between the first elastic plate and the second elastic plate, can well ensure that the positioning guide plate fits the human body The joint setting can effectively avoid the tight fit caused by muscle relaxation, and at the same time, the positioning guide plate has a certain A certain amount of stability.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a joint positioning guide plate based on medical images. Background technique [0002] Total knee arthroplasty has become an effective method for surgical treatment of end-stage knee osteoarthritis, rheumatoid arthritis and other diseases. It can effectively relieve knee pain, correct lower limb deformity and improve knee joint function. The key to TKR technology is to restore the normal anatomical force line of the lower limbs, deal with varus and varus of the knee joint, and reduce the occurrence of complications. [0003] With the rapid development of computer technology, space navigation technology and image processing technology, computer-aided navigation technology has been widely used in TKR surgery. The computer-aided navigation technology system is to form a three-dimensional visual image after the imaging data obtained before and during the operation are proces...

Problems solved by technology

It can perform simulated surgery, automatically select the most suitable size joint parts before the operation, simulate the operation, place sensors on the bone during the operation, and have an infrared camera on the navigation system to dynamically track the real-time spatial position of the surgical instrument relative to the patient's anatomical structure Based on this, the surgeon can accurately place the artificial joint, and use computer technology, space navigation technology, and 3D printing technology to make a joint positioning guide, which can well ensure that the produced joint positioning guide matches the patient's joints, and the joint positioning During the use of the guide plate, the patient’s joints and the operating table need to be connected with each other through screws, but the patient’s joints often cause the muscles of the joints to loosen due to operations during the operation, and the guide plate produced at this time cannot be very fast. If it fits the patient's joints well, it will have a great impact on the operation of the operation.
