[0001] The present invention relates to the technical field of annulus fibrosus suturing device, and particularly relates to an annulus fibrosus suturing device under spinal endoscope. Background Art

[0002] In the spinal structure, the annulus fibrosus is an important part of the intervertebral disc. It surrounds the nucleus pulposus and plays a role in stabilizing the spine and buffering pressure. However, due to factors such as aging, trauma, or bad postures, the annulus fibrosus may be damaged or ruptured, resulting in the protrusion of the nucleus pulposus, compressing the nerve root or spinal cord, and causing pain, numbness, or even dysfunction. In minimally invasive spinal surgery, suturing the annulus fibrosus is a challenging step. Due to the narrow surgical space, manual suturing is difficult to operate, and it is difficult to ensure the accuracy and stability of suturing. Based on this background, the annulus fibrosus suturing device came into being.

[0034] In order to make a clearer explanation and illustration of the technical solutions and implementation methods of the present invention, the following introduces the preferred specific embodiments for implementing the technical solutions of the present invention.

[0035] Embodiment 1: The spinal endoscope fiber ring stapler as a whole is composed of a stapler mechanism 1, a stapler tip 2, a suture anti - detachment sleeve 3, and a needle tube steering mechanism 4. The stapler handle 11 of the stapler mechanism 1 adopts an ergonomic arc design, which is convenient for doctors to hold and operate. The front end face of it is fixedly connected with a thread outlet needle tube 12 and a thread return needle tube 13, and the thread outlet needle tube 12 is located above the thread return needle tube 13. The front end of the curved needle 21 of the stapler tip 2 has a downward - bent arc, and the front end of the pointer 22 has a notch for receiving the suture spit out from the inside of the curved needle 21. The rear ends of the curved needle 21 and the pointer 22 are both fixedly connected with bellows 24, and the rear ends of the bellows 24 are respectively connected with the front ends of the thread outlet needle tube 12 and the thread return needle tube 13. The outer rear sides of the curved needle 21 and the pointer 22 are fixedly connected with a front side sleeve 25, and the outer front sides of the thread outlet needle tube 12 and the thread return needle tube 13 are fixedly connected with a rear side sleeve 23.

[0036] In the suture anti - detachment sleeve 3, the conical tube 31 is inlaid and fixed at the front - end port of the pointer 22. Six groups of silicone columns 34 are fixedly arranged in an annular array on the inner - cavity side wall of the conical tube 31. The inner - end head of the silicone column 34 is fixedly connected with a C - shaped rubber sheet 33. A wedge - shaped block 35 with a thin upper part and a thick lower part is fixedly connected to the outer - side wall of the C - shaped rubber sheet 33. A metal movable ring 37 is sleeved outside the wedge - shaped block 35. An electromagnet 32 adsorbed to the metal movable ring 37 is fixed in the bottom - space of the inner cavity of the conical tube 31. An inclined hole is formed inside the front - end head of the pointer 22, and the inclination angle of the inclined hole is the same as the inclination degree of the cut at the front - end head of the curved needle 21. The outer - ring surface of the conical tube 31 is fixedly connected with the side wall of the inner cavity of the inclined hole. The bottom - end face of the conical tube 31 is flush with the outer - ring surface of the pointer 22. The wedge - shaped block 35 is C - shaped and protrudes inward, and a transverse groove is provided on the surface of the side close to each other for clamping the suture. A number of fixing blocks 36 are fixedly arranged in an annular array on the inner - cavity side wall of the conical tube 31. The outer - ring surface of the electromagnet 32 is fixedly connected with the end of the fixing blocks 36 that gather together, and the adsorption end face faces the metal movable ring 37.

[0037] The front U - shaped seat 41 of the needle - tube steering mechanism 4 has a U - shaped vertical cross - section, and the rear U - shaped seat 42 has a U - shaped cross - section. The front - end of the front U - shaped seat 41 is fixedly connected with a front connecting column 47, and the rear - end of the rear U - shaped seat 42 is fixedly connected with a rear connecting column 43. The upper and lower surfaces of the front - end of the front connecting column 47 are fixedly connected with the mutually - close side walls of the front sleeve 25. The upper and lower surfaces of the rear - end of the rear connecting column 43 are fixedly connected with the mutually - close side walls of the rear sleeve 23. A cross - shaft 44 is rotatably arranged between the front U - shaped seat 41 and the rear U - shaped seat 42. A shaft pin is fixed on each of the upper, lower, left, and right side walls of the cross - shaft 44, and the shaft pins respectively penetrate through the 4 mutually - close end heads of the front U - shaped seat 41 and the rear U - shaped seat 42. Support plates 46 are fixedly arranged on the left and right side walls of the front U - shaped seat 41 and the upper and lower side walls of the rear U - shaped seat 42. A micro - electric push rod 45 is fixed on the mutually - close side walls of the support plates 46. The telescopic end head of the micro - electric push rod 45 on the front U - shaped seat 41 is hinged to the front - end head of the rear U - shaped seat 42, and the telescopic end head of the micro - electric push rod 45 on the rear U - shaped seat 42 is hinged to the rear - end head of the front U - shaped seat 41. A trigger for controlling the suture to spit out from the inner part of the outlet needle - tube 12 is arranged on the front side of the suture - stapler handle 11. The doctor controls the suture to spit out by operating the trigger, and uses the cooperation of the curved needle 21 and the pointer 22 for suture operation. When the direction of the needle - tube needs to be adjusted, the front U - shaped seat 41 and the rear U - shaped seat 42 are driven to rotate relative to each other through the telescopic movement of the micro - electric push rod 45 to realize the steering of the needle - tube. When the suture passes through the conical tube 31, the electromagnet 32 is energized to adsorb the metal movable ring 37, and the wedge - shaped block 35 clamps the suture under the action of the C - shaped rubber sheet 33 to prevent it from falling off.

[0038] Example 2: On the basis of Example 1, the structure of the tip 2 of the stapler is further optimized. The materials of the curved needle 21 and the pointer 22 are selected as high-strength and high-toughness medical stainless steel to improve their durability and puncture performance. The corrugated pipe 24 is made of medical silicone material with good flexibility and elasticity, which can not only ensure the soft connection between the curved needle 21 and the pointer 22 and the wire outlet needle tube 12 and the wire return needle tube 13, but also adapt to certain bending and twisting movements. The front side sleeve 25 and the rear side sleeve 23 are made of medical plastic material with a smooth surface to reduce friction with the surrounding tissues.

[0039] In the suture anti-detachment sleeve 3, the inner wall of the tapered tube 31 is polished to reduce the resistance when the suture passes through. The hardness of the silicone column 34 is moderate, which can not only provide sufficient support but also will not cause excessive extrusion to the suture. The elasticity of the C-shaped rubber sheet 33 is precisely adjusted to ensure that when the electromagnet 32 adsorbs the metal movable ring 37, the wedge block 35 can tightly hold the suture, and when the electromagnet 32 is powered off, the wedge block 35 can quickly release the suture.

[0040] The cross shaft 44 of the needle tube steering mechanism 4 is made of high-strength alloy steel material to ensure its rotation accuracy and stability. The stroke and thrust of the micro electric push rod 45 are precisely designed according to actual needs to ensure that the relative rotation angle of the front side U-shaped seat 41 and the rear side U-shaped seat 42 can be accurately controlled. During actual surgery, the doctor operates the trigger on the stapler handle 11 to precisely control the length and speed of the suture ejected from the wire outlet needle tube 12, and uses the cooperation of the curved needle 21 and the pointer 22 to accurately pass the suture through the annulus fibrosus tissue. When the suture direction needs to be adjusted, the needle tube steering mechanism 4 is driven by the micro electric push rod 45 to quickly and accurately adjust the curved needle 21 and the pointer 22 to the required angle. The suture anti-detachment sleeve 3 effectively prevents the suture from detaching during the suture passing process, improving the accuracy and reliability of the suture.

[0041] Example 3: On the basis of Example 1 and Example 2, some auxiliary functions are added. A display screen is set on the stapler handle 11 to display parameters such as the suture ejection length, the needle tube steering angle, and the power-on state of the electromagnet 32, which is convenient for the doctor to understand the working state of the stapler in real time. At the same time, sensors are set inside the stapler mechanism 1 to detect the tension and position of the suture. When the suture tension is too large or the position is abnormal, the sensors transmit signals to the control system, and the control system issues an alarm to remind the doctor.

[0042] In the suture anti - detachment sleeve 3, a temperature sensor is added to monitor the temperature inside the tapered tube 31 in real time, preventing damage to the suture caused by excessive temperature due to the long - term power - on of the electromagnet 32. In the needle tube steering mechanism 4, an angle limit device is set to limit the relative rotation angle between the front U - shaped seat 41 and the rear U - shaped seat 42, avoiding damage to the micro - electric push rod 45 and the cross - shaft 44 caused by excessive rotation. During actual surgery, the doctor can grasp the working parameters of the stapler in real time through the display screen and adjust the operation in a timely manner according to the feedback information of the sensor to ensure the safety and smoothness of the suturing process. For example, when the display screen shows that the suture tension is too high, the doctor can appropriately adjust the suture ejection speed or the direction of the needle tube; when the temperature sensor detects that the temperature inside the tapered tube 31 is too high, the control system automatically cuts off the power supply of the electromagnet 32 and resumes work after the temperature returns to normal. Through these auxiliary functions, the intelligence and safety of the fiber - ring stapler under spinal endoscopy are further improved.

[0043] According to the above - mentioned preferred technical solution content, the working process of this technical solution is described as follows: Before use, the stapler has been correctly assembled, and all components are firmly connected. It is confirmed that the suture anti - detachment sleeve 3 is in a normal working state, that is, the electromagnet 32 is in the off state, the metal movable ring 37 is not adsorbed, and the C - shaped rubber sheet 33 and the wedge - shaped block 35 are in a natural open state so that the suture can pass through smoothly.

[0044] The operator holds the stapler handle 11 and inserts the stapler tip 2, that is, the curved needle 21 and the pointer 22, into the surgical site through the working channel of the spinal endoscope and locates it at the position of the fiber ring to be sutured. When it is necessary to eject the suture, the operator presses the trigger on the front side of the stapler handle 11. After the trigger is pressed, it will trigger the suture - ejecting mechanism inside the stapler, and the suture will be pushed out from the inside of the wire - outlet needle tube 12. The ejected suture moves forward along the wire - outlet needle tube 12, passes through the incision at the front end of the curved needle 21, and enters the inclined hole inside the front end of the pointer 22.

[0045] When the suture enters the tapered tube 31, the suture will be located between the C - shaped rubber sheet 33 and the wedge - shaped block 35. At this time, the electromagnet 32 can be turned on. The electromagnet 32 will generate a magnetic field and adsorb the metal movable ring 37. After the metal movable ring 37 is adsorbed, it will move towards the direction of the electromagnet 32, thereby driving the C - shaped rubber sheet 33 and the wedge - shaped block 35 to tighten inward, clamping the suture tightly in the transverse groove of the wedge - shaped block 35 to prevent the suture from falling off from the tapered tube 31.

[0046] During the suturing process, it may be necessary to adjust the bending angles of the curved needle 21 and the pointer 22 according to the actual situation of the annulus fibrosus to facilitate better suturing. By controlling the telescopic movement of the micro electric push rod 45, the front U-shaped seat 41 and the rear U-shaped seat 42 can be driven to rotate relative to each other. Specifically, when the micro electric push rod 45 on the front U-shaped seat 41 extends, it will push the rear U-shaped seat 42 to rotate forward; when the micro electric push rod 45 on the rear U-shaped seat 42 extends, it will push the front U-shaped seat 41 to rotate backward. Through this relative rotation, the bending angles of the curved needle 21 and the pointer 22 can be changed to adapt to different suturing requirements.

[0047] After adjusting the suturing angle, the operator can move the suturing device so that the curved needle 21 and the pointer 22 pass through the part of the annulus fibrosus to be sutured. When the suture passes through the annulus fibrosus, the electromagnet 32 can be turned off, so that the metal movable ring 37 loses its adsorption force, and the C-shaped rubber sheet 33 and the wedge block 35 return to their original state under the elastic action of the silica gel column 34, releasing the clamping of the suture. At this time, the return wire needle tube 13 can be pulled to pull the suture out of the pointer 22, completing one suture. If necessary, the above steps can be repeated for multiple sutures until the annulus fibrosus is completely sutured.

[0048] The present invention is not limited to the above best implementation mode. Anyone should know that structural changes made under the inspiration of the present invention, as long as they have the same or similar technical solutions as the present invention, fall within the protection scope of the present invention. Finally, it should also be noted that the structures, proportions, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the limited conditions that the present application can be implemented. Therefore, they do not have technical essence. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the efficacy that the present application can produce and the purpose that can be achieved, should still fall within the scope that the technical content disclosed in the present application can cover.
