[0002] Minimally invasive spinal surgery has gradually become a major alternative to some open surgeries due to its smaller incision, less bleeding, shorter operation time, faster recovery, and lower complication rate. Spinal endoscopic surgery primarily utilizes a percutaneous endoscopic discectomy (PED) or arthroscopy to magnify the surgical field and uses water-based irrigation to ensure a clear surgical field. Based on the surgical technique, it is mainly divided into percutaneous endoscopic discectomy (PED) (foraminal approach and interlaminar approach), unilateral double-port endoscopy (UBE), and open single-port split endoscopy (OSE). Currently, existing minimally invasive spinal techniques use fixed-angle channels, and the position of the beam or the PED (or discoscope) is fixed. When the view is obstructed, adjustments are difficult, resulting in low efficiency. Utility Model Content

[0028] The following is combined Figures 1-6 This invention describes a minimally invasive spinal access channel. The minimally invasive spinal access channel includes: an operating channel 1, an observation channel 2, and an adjustment unit 3.

[0029] The first end of the observation channel 2 is hinged to the first end of the operation channel 1; the adjustment unit 3 is connected between the second end of the operation channel 1 and the second end of the observation channel 2, and the adjustment unit 3 can extend and retract to adjust the angle of the observation channel 2.

[0030] Taking percutaneous endoscopic discectomy (PED) as an example, observation channel 2 and operating channel 1 are two core components that work together to complete the surgery. Observation channel 2 (the endoscope channel) contains an endoscope (equipped with a camera and a cold light source), allowing the surgeon to clearly see real-time images of the spinal canal on a monitor, including structures such as herniated discs, compressed nerve roots, the dural sac, and bone hyperplasia. Operating channel 1 (the working channel), running parallel to observation channel 2, is used by the surgeon to insert various delicate surgical instruments into the spinal canal for actual manipulation. In existing technologies, operating channel 1 and observation channel 2 are at fixed angles, making adjustment difficult when the view is obstructed, causing inconvenience and low efficiency during surgery.

[0031] To address the aforementioned problems in the prior art, this invention provides an adjustment unit 3 between the operation channel 1 and the observation channel 2. The first end of the observation channel 2 is hinged to the first end of the operation channel 1. By providing the adjustment unit 3 between the second end of the operation channel 1 and the second end of the observation channel 2, the adjustment unit 3 can extend and retract, thereby adjusting the angle between the observation channel 2 and the operation channel 1.

[0032] During surgery, the extension and retraction of the adjustment unit 3 can be adjusted to a suitable tilt angle between the observation channel 2 and the operation channel 1, which facilitates observation and surgical operation and improves efficiency.

[0033] Furthermore, a mounting plate is provided on the outside of the operating channel 1. The mounting plate has a groove to facilitate positioning in conjunction with other components.

[0034] This invention provides a minimally invasive spinal access channel, comprising: an operating channel 1, an observation channel 2, and an adjustment unit 3. The first end of the observation channel 2 is hinged to the first end of the operating channel 1; the adjustment unit 3 is connected between the second end of the operating channel 1 and the second end of the observation channel 2, and the adjustment unit 3 is capable of telescopic movement to adjust the angle of the observation channel 2. In this minimally invasive spinal access channel, the first end of the observation channel 2 is hinged to the first end of the operating channel 1. By setting the adjustment unit 3 between the second end of the operating channel 1 and the second end of the observation channel 2, the adjustment unit 3 can telescopically adjust the observation channel 2 and the operating channel 1 to a suitable tilt angle, facilitating observation and surgical operation and improving efficiency.

[0035] Example 1: like Figure 1 and Figure 2 As shown, in this embodiment, the adjustment unit 3 includes a folding plate 301, with its first end connected to the second end of the operation channel 1 and its second end connected to the second end of the observation channel 2.

[0036] Specifically, the folding plate 301 is composed of multiple retractable and foldable plates connected together. The distance between adjacent plates can be manually adjusted to achieve the retractable movement of the folding plate 301. To achieve positioning of the folding plate 301, connecting rods can be set between the folding plates 301, and positioning components are set on the connecting rods. The positioning of the folding plate 301 is achieved by locking the positioning components. The folding plate 301 is preferably made of corrosion-resistant and easy-to-clean materials such as stainless steel, and can withstand high temperature and high pressure sterilization to ensure a sterile surgical environment. The folding parts connecting the plates can adopt a movable connection method, such as setting hinges.

[0037] In this embodiment, the adjustment unit 3 further includes a first sleeve 302 and a second sleeve 303. The first sleeve 302 is fitted onto the outside of the operation channel 1 and connected to the first end of the folding plate 301; the second sleeve 303 is fitted onto the outside of the observation channel 2 and connected to the second end of the folding plate 301.

[0038] Specifically, the first set 302 and the second set 303 are respectively fitted onto the outer walls of the operation channel 1 and the observation channel 2, and are respectively connected to the plates located at both ends, thereby realizing the connection between the folding plate 301 and the operation channel 1 and the observation channel 2. Specifically, the first set 302 and the second set 303 are made of rubber material and are wrapped around the outer walls of the operation channel 1 and the observation channel 2.

The second connecting seat 306 is fixed to the second end of the operation channel 1; the connecting block 307 is hinged to the second connecting seat 306; the first end of the screw 308 is fixed to the connecting block 307, and the second end is threadedly connected to the threaded sleeve 305.

[0042] Specifically, the first connecting seat 304 and the second connecting seat 306 are respectively fixed on the outer walls of the operating channel 1 and the observation channel 2. The first connecting seat 304 and the threaded sleeve 305 are hinged together, the screw 308 is fixed on the connecting block 307, and the second connecting seat 306 is hinged to the connecting block 307. Through the above-mentioned hinged connection method, the normal extension and retraction movement of the two is ensured when the screw 308 rotates in the threaded sleeve 305.

[0043] In this embodiment, the first connecting seat 304 has a first positioning hole, the screw sleeve 305 has a second positioning hole, and the second positioning hole and the first positioning hole are connected by a rotating pin; the second connecting seat 306 has a third positioning hole, the connecting block 307 has a fourth positioning hole, and the fourth positioning hole and the third positioning hole are connected by a rotating pin.

[0044] Specifically, the first connecting seat 304 and the threaded sleeve 305 are rotatably connected by a positioning hole and a rotating pin, and the second connecting seat 306 and the connecting block 307 are also rotatably connected by a positioning hole and a rotating pin.

[0045] In this embodiment, the adjustment unit 3 further includes a rotary handle 309, which is located on the outside of the screw 308. Specifically, the rotary handle 309 is fixed to the outside of the screw 308 and has a serrated structure to increase friction. In use, manually rotating the rotary handle 309 can drive the screw 308 to rotate synchronously, thereby realizing the telescopic movement between the screw 308 and the sleeve 305.

The minimally invasive spinal channel also includes a silicone pad 501 and a nut 5. The silicone pad 501 is disposed on the inner wall of the second end of the observation channel 2; the nut 5 is connected to the threaded portion and encapsulates the silicone pad 501. In this embodiment, by providing the silicone pad 501 on the inner wall of the second end of the observation channel 2, elastic positioning and damping functions are provided, facilitating the insertion of the camera and cold light source into the observation channel 2 through the silicone pad 501; a groove for installing the silicone pad 501 is formed on the inner wall of the observation channel 2, and the silicone pad 501 is encapsulated and fixed in the observation channel 2 by the cooperation of the nut 5 and the threaded portion.

[0047] In Examples 1 and 2, as Figure 6 As shown, the minimally invasive spinal access channel also includes: a connector plate 601 and a connector seat 602 (the connector plate 601 and connector seat 602 are not shown in the attached figures of Embodiment 1, but their specific structures are the same as those in Embodiment 2). The connector plate 601 is fixed to the first end of the operating channel 1; the connector seat 602 is fixed to the first end of the observation channel 2, and the connector seat 602 has a connector groove. The connector plate 601 and the connector groove are connected by a rotating pin. Specifically, the connector plate 601 and the connector groove each have a positioning hole. The rotating pin is inserted into the positioning hole to achieve a rotatable connection between the connector plate 601 and the connector seat 602.

[0048] In Embodiments 1 and 2, the minimally invasive spinal channel further includes an overflow hole 4, located near the second end of the operating channel 1 and connected to it. Specifically, the overflow hole 4 is connected to an overflow tube. During use, blood and other fluids are drained through the overflow hole 4 to prevent them from overflowing from the operating channel 1.
