Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a spinal surgery retracting device.
Background
Retractors provide surgeons with access to surgical sites, such as during spinal surgery, for example discectomy, laminectomy, facetectomy (facectomy), interbody fusion, pedicle screw fixation, and similar procedures. Common spinal surgery is performed using an open procedure that results in a relatively large incision, the destruction or removal of important soft tissue, and a long recovery time for the patient. Minimally invasive techniques have become increasingly popular, particularly for spinal surgery, wherein surgical procedures are performed on a patient using relatively small incisions and surgical access, often resulting in smaller incisions or multiple relatively small incisions, less soft tissue retraction and resection, and shorter recovery times for the patient than open procedures. In some cases, minimally invasive procedures can achieve comparable or improved long-term surgical results compared to open procedures and can provide short-term advantages, including reduced post-operative pain, reduced post-operative use of anesthetics, reduced tissue destruction (thereby enabling reduced scar tissue and having potential advantages (when revision is needed)), reduced blood loss, reduced recovery time, shorter hospital stays, and smaller incisions with cosmetic requirements. However, a smaller incision reduces the surgeon's line of sight to directly view the surgical site because the patient's soft tissue often limits the surgeon's ability to view the surgical site.
However, the complex procedures and instruments used in some minimally invasive spinal surgeries often require removal and replacement of the different instruments by closing the cannula or sleeve, thereby fatiguing the surgeon and extending the time of the surgery and anesthesia of the patient. Moreover, when complex procedures and instruments are used, the complex procedures and instruments may cause surgical delays, particularly for newly trained or novice medical personnel and surgeons, and some of the existing spinal surgical retraction devices are inconvenient to secure to the bedside or the frame and may slip easily, so that it is necessary to design a new type of spinal surgical retraction device to solve these problems.
