Description

Technical Field

[0001] The present invention relates to the technical field of minimally invasive positioning of a perforaminal endoscopic disc, and in particular to a precise locator for a minimally invasive channel of a perforaminal endoscopic disc. Background Art

[0002] In modern medicine, minimally invasive surgical techniques are widely used due to their advantages of minimal trauma, rapid recovery, and few complications. Transforaminal endoscopic lumbar discectomy (PES), a key minimally invasive technique, is primarily used to treat spinal conditions such as herniated discs and spinal stenosis. This technique involves inserting small instruments into the intervertebral foramen to directly perform lesion removal or other treatments, significantly minimizing damage to surrounding tissues and improving surgical safety and effectiveness. While PES has achieved remarkable success in clinical practice, it still faces several challenges. First, precise positioning is crucial for successful surgery. Traditional positioning methods rely heavily on the surgeon's experience and the assistance of intraoperative imaging equipment, which carries a certain risk of error. Second, due to the complex anatomy of the intervertebral foramen, injury to adjacent nerves and blood vessels is difficult to avoid during surgery. Furthermore, postoperative complications such as infection, bleeding, and nerve damage remain pressing issues. PES, a minimally invasive technique that accesses the intervertebral foramen through a small incision to treat the intervertebral disc, nerve roots, and surrounding tissues, is increasingly being used in spinal surgery due to its minimal trauma and rapid recovery. However, the success of the surgery depends heavily on the precise positioning of the surgical instruments. To this end, we designed a precise locator for minimally invasive perforaminal endoscopic discectomy to improve the safety and effectiveness of the operation.

[0003] During the use of the precise locator, since the patient's lumbar spine requires minimally invasive surgery, the irradiation light spot needs to be accurately positioned on the patient's lumbar spine. If the patient's waist cannot be temporarily restrained and shifted, the light spot cannot be accurately positioned at the minimally invasive part of the lumbar spine, causing the doctor to be unable to accurately perform minimally invasive surgery on the patient's lumbar spine. Summary of the Invention

[0004] The present invention relates to a precise locator for a minimally invasive percutaneous endoscopic lumbar channel. The arc-shaped protrusion of the device first lifts the patient's chest and abdomen to arch the lumbar spine at the back, and by lifting the chest and abdomen, causes the lumbar spine to kyphosis, directly exposing the target intervertebral space or vertebral plate, reducing obstruction of soft tissue. This posture adjustment facilitates the doctor to quickly locate the surgical site through imaging equipment (such as X-ray or CT), shortens the preoperative preparation time, and facilitates the light spot irradiated by the irradiation tube to be aimed at the minimally invasive part of the patient's lumbar spine for positioning. The two limiting plates firmly clamp the patient's two sides to prevent waist displacement. The bilateral splints fix the patient's torso to prevent lumbar displacement caused by muscle relaxation or accidental movement during the operation. Especially under local anesthesia, the patient may move due to pain or tension. The limiting design can prevent the instrument from accidentally damaging nerves or blood vessels, and facilitates the doctor to perform minimally invasive surgery at the patient's lumbar positioning site.

[0005] In a first aspect, the present invention provides a precise locator for a minimally invasive transforaminal endoscopic lumbar disc, comprising: a supporting plate; four rectangular slots are formed on the upper end of the supporting plate, and threaded slots are formed at both ends of the rectangular slots; mutually symmetrical support bases are mounted at the lower end of the bottom of the supporting plate, and universal wheels are mounted at the four corners of the bottom of the support bases; mutually symmetrical fixing brackets are fixedly mounted in the four rectangular slots of the supporting plate, and fixing holes are formed at the rear ends of the upper ends of the fixing brackets; A crossbeam plate is slidably mounted on the upper ends of the two fixing frames at opposite ends, and a slot is provided on the upper end of the crossbeam plate; an arc-shaped protrusion is installed in the middle of the upper end of the bearing plate; protective plates are fixedly mounted on both ends of the arc-shaped protrusion; fixing holes are respectively provided in the middle of the two protective plates, and four anti-drop holes are provided on the protective plates; and electric rods are fixedly mounted on the fixing holes of the two protective plates; Limit plates are fixedly installed on the opposite ends of the two electric rods, and four anti-slip rods are fixedly installed on the side walls of the limit plates. Extension plates are fixedly installed on the front side walls of the two protective plates, and a through limiting opening is opened on the extension plate. A through light plate is inserted in the limiting opening, a baffle is fixedly installed on the upper end of the light plate, and hooks are evenly installed on the bottom of the light plate.

[0006] Furthermore, a buffer groove is provided in the middle of the upper end of the supporting plate, and a fixing groove is provided in the middle of the buffer groove. Mutually symmetrical guide holes are provided at both ends of the supporting plate, and a hydraulic cylinder is fixedly installed at the fixing groove in the middle of the buffer groove.

[0007] Furthermore, the upper ends of the two support bases are respectively fixedly mounted with electric push rods, the lower ends of the two electric push rods are respectively fixedly mounted with stabilizing plates, and a circle of bolts is inserted on the stabilizing plates, and two vertically upward guide rods are respectively fixedly mounted on the two support bases.

[0008] Furthermore, the two ends of the lower ends of the two fixing frames are respectively fixed with symmetrical side ear plates, and the side ear plates are inserted with penetrating bolts. The upper ends of the two fixing frames are respectively provided with rail openings, and telescopic rods are respectively fixed with the fixing holes of the two fixing frames.

[0009] Furthermore, a display screen is fixedly mounted on the card slot of the crossbeam plate, track blocks are fixedly mounted on both sides of the crossbeam plate, and an electric push rod A is fixedly mounted on the right end of the upper end of the crossbeam plate.

[0010] Furthermore, the crossbeam plate is provided with mutually symmetrical anti-slip openings, and an anti-slip frame is slidably installed at the anti-slip openings. A circular hole is provided in the middle of the lower end of the anti-slip frame, and a small electric rod is fixedly installed through the circular hole of the anti-slip frame.

[0011] Furthermore, a connecting plate is fixedly mounted on the lower end of the small electric rod, and three penetrating screws are inserted into the connecting plate. A connecting mold is mounted on the bottom of the connecting plate.

[0012] Furthermore, a penetrating irradiation tube is installed in the middle of the connecting mold, and a camera is installed at the bottom of the connecting mold.

[0013] The present invention provides a precise locator for a minimally invasive transforaminal endoscopic lumbar disc, which has the following beneficial effects: When the precise locator of the present invention is in use, during the process of minimally invasive lumbar surgery on the patient, the arc-shaped protrusion first lifts the patient's chest and abdomen to arch the lumbar spine at the back, and by lifting the chest and abdomen, the lumbar spine is convexed, directly exposing the target intervertebral space or vertebral plate, reducing the obstruction of soft tissue. This posture adjustment makes it convenient for doctors to quickly locate the surgical site through imaging equipment (such as X-ray or CT), shortening the preoperative preparation time, and facilitating the alignment of the light spot irradiated by the irradiation tube with the patient's minimally invasive lumbar spine for positioning. The two limiting plates firmly clamp the patient's two sides to avoid waist displacement, and the bilateral splints fix the patient's torso to prevent lumbar displacement caused by muscle relaxation or accidental movement during the operation. Especially under local anesthesia, the patient may move due to pain or tension. The limiting design can prevent the instrument from accidentally injuring nerves or blood vessels, making it convenient for doctors to perform minimally invasive surgery at the patient's lumbar positioning site.

[0014] In addition, a small electric rod is used to move the irradiation tube and camera downward to create an appropriate distance between the irradiation tube and the patient's back. When the irradiation tube is turned on, it will emit a focused blue light spot. The camera can provide high-resolution regional images. The camera can magnify the surgical area several to dozens of times through the display screen, clearly displaying fine structures such as intervertebral discs, nerve roots, and blood vessels, reducing the risk of accidental injury to surrounding tissues. The distance between the irradiation tube and the patient's back is precisely adjusted through the electric rod to ensure that the light spot is focused on the target area (such as the intervertebral disc or nerve root), avoiding improper distance caused by manual operation errors (too close may burn tissue, too far will cause the light spot to diverge).

[0015] In addition, using hooks to hook the pulled top, pulling the top upward and fixing it with hooks can prevent the clothes from sliding down and interfering with the surgical area (such as the L1-L5 lumbar vertebrae) during the operation, and avoid frequent adjustments of body position that affect surgical accuracy. According to the lumbar structure of each patient, a hydraulic cylinder is used to slowly push the arc-shaped protrusion upward, and the arc-shaped protrusion is used to lift the patient's chest. At this time, the patient's lumbar spine will also arch, widening the posterior intervertebral space, especially the L4-L5, L5-S1 and other segments. It is easier for doctors to insert puncture needles, interlaminar foraminal endoscopes or minimally invasive instruments, reducing the risk of compression on the nerve roots, reducing the difficulty of operation, and making it easier for doctors to perform minimally invasive surgery on the patient's lumbar spine.

[0016] By using the side walls of the two limiting plates to firmly clamp the patient's sides, the patient is restricted by the side walls of the two limiting plates and will not easily turn over or move. The clamping of the limiting plates can prevent the patient's position from shifting due to unconscious movement or muscle contraction, ensuring the stability of the surgical target position and making it easier for doctors to perform minimally invasive surgery on the patient's lumbar spine.

[0022] Among them, a buffer groove 101 is provided in the middle of the upper end of the supporting plate 1, and a fixed groove is provided in the middle of the buffer groove 101. The lower end of the arc-shaped protrusion 5 is installed in the buffer groove 101. Mutually symmetrical guide holes 102 are provided at both ends of the supporting plate 1. A hydraulic cylinder 103 is fixedly installed at the fixed groove in the middle of the buffer groove 101. The upper end of the hydraulic cylinder 103 is fixedly connected to the bottom of the arc-shaped protrusion 5. According to the lumbar vertebra structure of each patient, the hydraulic cylinder 103 is used to slowly push the arc-shaped protrusion 5 upward, and the arc-shaped protrusion 5 is used to lift the patient's chest. At this time, the patient's lumbar vertebra will also be arched, which is convenient for the doctor to perform minimally invasive treatment on the patient's lumbar vertebra. The upper ends of the two supporting bases 2 are respectively fixedly installed with electric push rods 201, and the two electric push rods 201 are installed with a synchronous operation system. The upper ends of the two electric push rods 201 are fixedly connected to the bottom of the supporting plate 1. The two electric push rods 201 are used to push the supporting plate 1 upward at the same time, and then move the supporting plate 1 to the top of the bed. When the support plate 1 is moved up and down, the guide holes 102 on the support plate 1 are restricted by the guide rods 203, and the support plate 1 can only slide up and down to prevent the support plate 1 from tilting when sliding up and down, and the support plate 1 cannot be stably attached to the bed.

[0023] Among them, the two ends of the lower ends of the two fixing frames 3 are respectively fixed with symmetrical side ear plates 301, and the side ear plates 301 are inserted with through bolts. The upper ends of the two fixing frames 3 are respectively opened with track openings 302, and the fixing holes of the two fixing frames 3 are respectively fixed with telescopic rods 303. The two telescopic rods 303 are installed with a synchronous operation system. The two telescopic rods 303 can move the cross beam 4 back and forth at the same time. The front ends of the two telescopic rods 303 are respectively fixedly connected to the two track blocks 402. When the two telescopic rods 303 are used to move the cross beam 4 back and forth, the anti-slip frame 405 installed on the cross beam 4 will also move with it, so as to facilitate the irradiation tube 409 on the anti-slip frame 405 to accurately locate the patient's lumbar spine and perform minimally invasive surgery on the patient's lumbar spine.

[0024] Among them, the display screen 401 is fixedly mounted on the card slot of the crossbeam plate 4, and track blocks 402 are fixedly mounted on both sides of the crossbeam plate 4. The track blocks 402 are slidably mounted in the track openings 302. When the crossbeam plate 4 slides back and forth, the track blocks 402 are restricted by the track openings 302, and the crossbeam plate 4 can only slide back and forth to prevent the crossbeam plate 4 from tilting when sliding back and forth. An electric push rod A403 is fixedly mounted on the right end of the upper end of the crossbeam plate 4, and the left end of the electric push rod A403 is fixedly connected to the side wall of the upper end of the anti-slip frame 405. The electric push rod A403 can be used The anti-slip frame 405 is moved left and right to adjust its position. At the same time, the position of the irradiation tube 409 and the camera 410 at the lower end of the anti-slip frame 405 is also adjusted, so that the light spot emitted by the irradiation tube 409 is aimed at the minimally invasive part of the patient's lumbar spine, and the minimally invasive part of the patient is accurately positioned. Then the doctor will perform minimally invasive surgery on the patient's lumbar spine. The crossbeam 4 is provided with mutually symmetrical anti-slip openings 404, and the anti-slip openings 404 are slidably installed with an anti-slip frame 405, which is slidably installed in the anti-slip openings 404. When the anti-slip frame 405 slides left and right, the anti-slip frame 405 is affected by the anti-slip openings 404. 04 is limited to sliding left and right, and a round hole is opened in the middle of the lower end of the anti-slip frame 405, and a small electric rod 406 is fixedly installed on the round hole of the anti-slip frame 405. The small electric rod 406 is used to move the irradiation tube 409 and the camera 410 downward to create a suitable distance between the irradiation tube 409 and the patient's back. The camera 410 can provide high-resolution regional images. The camera 410 can magnify the surgical area several times to dozens of times through the display screen 401, clearly showing fine structures such as intervertebral discs, nerve roots, and blood vessels, reducing misunderstanding of surrounding tissues. To avoid injury risk, a connecting plate 407 is fixedly installed at the lower end of the small electric rod 406, and three penetrating screws are inserted on the connecting plate 407. The connecting mold 408 is firmly connected through the screws on the connecting plate 407. At this time, the connecting plate 407 will be fixedly connected to the connecting mold 408. The connecting mold 408 is installed at the bottom of the connecting plate 407. A penetrating irradiation tube 409 is installed in the middle of the connecting mold 408. When the irradiation tube 409 is started, a focused blue light spot will be emitted. A camera 410 is installed at the bottom of the connecting mold 408.

[0025] Example 2, based on Example 1, Figure 1 and Figure 8 As shown, the lower ends of the two electric push rods 201 are respectively fixed with a stabilizing plate 202, and a circle of bolts is inserted on the stabilizing plate 202. The stabilizing plate 202 and the bolts are removed, and then the bottom of the electric push rod 201 is fixedly welded to the supporting base 2 to firmly restrict the electric push rod 201. In this way, the electric push rod 201 will not fall over when touched, avoiding the loosening of the bolts due to long-term use and the inability to stabilize the electric push rod 201, while also saving the cost of parts.

[0026] The working principle of this embodiment is as follows: when in use, two electric push rods 201 are used to push the supporting plate 1 upward at the same time, and then the supporting plate 1 is moved to the top of the bed, and the supporting plate 1 is moved downward according to the height of the bed board, and the supporting plate 1 is placed steadily on the bed board. At this time, the bed board can support the supporting plate 1 and the patient, and then the patient's top is pulled toward the head, and then the light plate 508 is moved downward, and the hook 509 is used to hook the pulled top so that the top cannot move toward the waist. When the patient is undergoing intervertebral foramina surgery, During minimally invasive surgery, the patient's chest lies on the arc-shaped protrusion 5, and two electric rods 503 are used to push the two limit plates 504 in opposite directions. The side walls of the two limit plates 504 are used to firmly clamp the patient's two sides. At this time, the patient is blocked and restricted by the side walls of the two limit plates 504, and the patient will not turn over or move easily. According to the lumbar structure of each patient, the hydraulic cylinder 103 is used to slowly push the arc-shaped protrusion 5 upwards, and the arc-shaped protrusion 5 is used to lift the patient's chest. At this time, the patient's lumbar spine will also arch, and the two extension rods are used. The retraction rod 303 moves the crossbeam 4 back and forth, and the anti-slip frame 405 installed on the crossbeam 4 will also move accordingly. Then, the electric push rod A403 can be used to move the anti-slip frame 405 left and right to adjust its position. At the same time, the position of the irradiation tube 409 and the camera 410 at the lower end of the anti-slip frame 405 is also adjusted. At this time, the position of the irradiation tube 409 and the camera 410 can be moved back and forth, left and right, so that the light spot emitted by the irradiation tube 409 is aimed at the minimally invasive part of the patient's lumbar spine, and the minimally invasive part of the patient is accurately positioned. When the irradiation tube 409 is started, a concentrated blue light spot will be emitted. The small electric rod 406 is used to move the irradiation tube 409 and the camera 410 downward to create a suitable distance between the irradiation tube 409 and the patient's back. The camera 410 can provide high-resolution regional images. The camera 410 can magnify the surgical area several times to dozens of times through the display screen 401, clearly displaying fine structures such as intervertebral discs, nerve roots, and blood vessels, reducing the risk of accidental injury to surrounding tissues, and making it convenient for doctors to perform minimally invasive surgery on the patient's lumbar spine.
