Description

Assisted imaging positioning kit

This invention relates to an auxiliary imaging positioning kit.

With the advancement of medical equipment, surgical wounds have gradually entered the era of minimally invasive surgery. The development of minimally invasive wound surgery has been the main topic of orthopedic and spinal surgery in recent years. The biggest advantage of minimally invasive surgery is that it reduces tissue trauma with small wounds, allowing the surgical site to heal as soon as possible. However, the success of minimally invasive surgery depends on the accuracy of the incision. If the incision location can be accurately determined before the incision is made, the wound does not need to be enlarged or increased, and the recovery time after surgery can be shortened and the risk of infection can be reduced.

C-arm X-ray cameras are commonly used tools in orthopedic surgery because of their high mobility, fast imaging speed, and low imaging cost. In practice, in order to effectively confirm the position of the tool, the C-arm X-ray camera must be used frequently to update the image. This causes patients to be exposed to high doses of radiation during surgery. For medical staff, long-term accumulated radiation doses will also pose a serious threat to their health. Therefore, how to effectively reduce the use of C-arm X-ray cameras and maintain or even improve surgical accuracy is an important consideration for both patients and medical staff.

In practice, radiographic positioning is often used before surgery, and the doctor then uses experience to infer the incision position based on the images of each film. For example, in minimally invasive spinal surgery, the incision is 1.5-2 cm, and the incision position must be very accurate. Traditional positioning is to place instruments on the lesion site, or to pierce a hole with a needle as a positioning mark. Please refer to Appendix 1, which is an X-ray photo of an example of traditional positioning using instruments placed on the lesion site to assist in positioning.

However, puncturing with a needle can easily cause unnecessary pinholes in patients. Placing instruments at the lesion site as a surgical incision mark and then marking it, for minimally invasive surgery, surgical markings are made in centimeters, and it is often impossible to accurately grasp the marking distance. In addition, with traditional instrument positioning methods, there are also situations where the instrument blocks the positioning image display. Therefore, how to develop a marker that can be marked on the patient before surgery to provide a reference and auxiliary display mark when taking X-ray images is an important topic, in order to improve the accuracy of surgical site positioning, achieve minimally invasive wound surgery, and shorten the patient's surgical recovery period. While increasing accuracy, it also reduces the number and amount of radiation exposure during positioning, reduces the time surgical medical staff are exposed to radiation, and improves the operating room environment and occupational safety. This is a clinical problem that needs to be solved urgently.

Previous technologies have revealed that imaging positioning gel can solve the above clinical problems. However, there is no device that assists in applying imaging positioning gel on the patient's body, which makes the clinical application of imaging positioning gel very inconvenient.

Therefore, one of the technical problems that the present invention aims to solve is to provide an auxiliary imaging positioning kit in which an auxiliary imaging positioning gel is applied on the patient's body.
