Minimally invasive surgery, as a hot spot for future surgical development, is believed to be no stranger, and in recent years, a new member of this family has been added to the field of orthopedics: discoscopic technology. The cone discoscopic surgery technique belongs to the family of (MED) endoscopic techniques. Like all endoscopic techniques, the discoscopic technique has the advantages of small wound, good field of view and illumination conditions, short hospitalization time and fast physical recovery. The entire discoscopy system consists of several systems such as camera system, surgical instruments, access accessories, and recording system. The camera system consists of cameras, optical fibers and light bulbs, which are responsible for providing lighting and real-time camera functions in the surgical area, while the surgical instruments are “small but complete”, ranging from various types of nucleus pulposus forceps, to cleverly conceived hook-shaped suction tubes, to scrapers designed for different directions of operation. The complete combination is a powerful guarantee of the powerful function of discoscopic technology. The snake-shaped free arm, which can be bent in multiple directions in three-dimensional space, extends freely when loosened, as its name implies, and is as strong as an iron wrist and steel arm when tightened. With this tool, the discoscopy system can significantly expand the operating space and complete the operation of multiple segments. If the design of the discoscope is ingenious, how does it work in practice? Let’s take a look at a disc nucleus pulposus procedure performed with the discoscope system. After the routine sterilization of the sheet, the operator fixes the fixed arm next to the operating table and attaches the serpentine free arm. A small 1.5-cm incision is made in the patient’s back at the projection of the patient’s spinal space. At this point, the dilating tube comes into play. Starting with the smallest tube, a larger dilator tube is applied layer by layer. Each layer of the dilatation tube reached all the way down to the surface of the vertebral plate. Thus, a skin incision of only 1.5 cm was dilated little by little into an aperture of 1.8 cm in diameter. Don’t underestimate this 1.8 cm diameter, but it is the entire space of the entire operation, from the cortex, subcutaneous tissue, and muscle layer to the outside of the vertebral plate. Looking directly down through the incision, it is simply a tunnel hit in the body, how can this be operated? Don’t worry, this problem is solved when we connect to the camera lighting system. The endoscope can magnify the image up to 64 times, and the lighting device can provide a bright, stable light source, and more because the camera is close to the surgical operation area. As a result, reflected on the screen, the vertebral morphology, blood vessels and other tissues are much clearer than they normally are in similar procedures. Of course, this has placed higher demands on the operator, because a slight movement by the operator will be magnified several times on the screen, so that the entire discoscopic operation is very fine and accurate. It is this high demand on the operation that ensures minimal surgical damage and complete patient removal. The relatively confined surgical area and the high precision of the operation have given rise to a set of delicate surgical instruments. These seemingly ordinary surgical instruments are coated with a black surface to reduce surgical reflections. The surgical operation part of the instruments has a precise scale to guarantee the operator’s mastery of the operation scale. The entire instrumentation system is highly stable, and the main components can be autoclaved, allowing multiple discoscopic surgical operations to be performed in a single day. Thus, although the basic operation and principles of surgery are the same, we will be surprised when we finish the operation to find that the entire skin incision can be covered with a Band-Aid, making it truly “minimally invasive”. As a new member of the minimally invasive surgery family, may the discoscopic technology, which “removes patients within an inch of their lives,” thrive for the benefit of more patients.
