Involving a medical device, specifically a ball probe.
Background technology:
In the surgical treatment of spinal patients, it is often necessary to insert pedicle screws for fixation. The traditional treatment method is for doctors to manually insert pedicle screws into the patient's body using the spine. Due to the sharp front end of the bone cone, the insertion force is difficult to grasp, which can easily penetrate the cortical bone of the pedicle and may also damage the patient's spinal cord, nerve roots, viscera, or large blood vessels, posing a significant risk.
The usual method now is to use a ball head probe in conjunction with a neural monitor and disposable electrode to help doctors accurately insert pedicle screws. However, the existing ball head probes have a straight needle rod, and when doctors need to observe the placement position, they often adjust the angle of the ball head probe significantly due to the difference between the surgical wound and the target position, which can cause secondary damage to the surgical wound.
Therefore, it is necessary to design a ball probe to solve the problem of secondary damage to the surgical wound caused by significant adjustment of the ball probe angle due to the difference between the surgical wound and the target position in existing technology.
