Description

Technical Field

[0001] The utility model relates to the field of retinal membrane stripping, in particular to a vitrectomy light guide fiber combined with a membrane stripper. Background Art

[0002] Modern vitrectomy primarily utilizes a closed three-port incision through the pars plana. These three ports are used for irrigation, illumination, and instrument manipulation, respectively. In complex cases with significant retinal proliferation, such as severe PDR and severe PVR, two-handed retinal peeling is often required. The cleanliness of the peeling is directly related to surgical outcome. However, during current intravitreal procedures, the left hand is used to control the light guide, leaving the right hand alone for peeling, significantly limiting the procedure. In practice, the narrow size of the eye and the limited intensity and range of light during surgery create significant inconvenience for medical personnel. This can lead to iatrogenic retinal tears, resulting in retinal breaks and hemorrhage, as well as multiple incisions into the sclera, resulting in pigment membrane detachment and incisional tears. Some surgeons utilize a four-port procedure, adding an additional port to house a ceiling light, allowing for hands-free intravitreal procedures. However, this increases the risk of complications such as cataracts and retinal detachment. Furthermore, the ceiling light's limited illumination angle and range impair illumination for certain quadrants.

[0003] In the existing technology, most of the film strippers are unable to adjust the telescopic stripper head, resulting in the film stripper head being exposed to the outside for a long time and being contaminated by dust due to contact with the air. The film stripper head cannot be protected, thereby affecting the service life of the film stripper head. In addition, the film stripper is not easy to pick up, cannot play an anti-slip role, and cannot be connected to the hand, resulting in inconvenience in operation during surgery and affecting work efficiency.

[0004] With regard to the existing technical structure, the structure without telescopic adjustment cannot make the film stripper head telescopically adjustable inside the light guide head, and it cannot be retracted into the light guide head, resulting in it being exposed to the outside and in contact with the air. Not only can it not provide protection, it also cannot play a dust-proof role. In addition, the film stripper is not convenient to hold for a long time during the operation, resulting in inconvenience in operation during the operation. Utility Model Content

[0025] Reference Figure 1 - Figure 4The utility model provides an embodiment of a glass-cut optical fiber combined with a film stripper, comprising a light guide head 1, a handle 2 fixedly connected to the outer wall of the light guide head 1, a switch 5 fixedly connected to the upper surface of the handle 2, a fixing rod 9 fixedly connected to the interior of the light guide head 1, a nut sleeve 11 rotatably connected to the outer wall of the light guide head 1, the fixing rod 9 slidably connected to the interior of the nut sleeve 11, a slide groove 13 is provided inside the nut sleeve 11, the fixing rod 9 is slidably connected to the interior of the slide groove 13, and a clamping plate 10 is fixedly connected to the outer wall of the fixing rod 9. A limiting groove 12 is provided inside the nut sleeve 11, and the clamping plate 10 is slidably connected to the inside of the limiting groove 12. The inner thread of the nut sleeve 11 is connected to the outer tube 8, and the outer wall of the outer tube 8 is provided with a threaded groove. The outer wall of the outer tube 8 is fixedly connected to the film stripper head 7. A light guide component is provided inside the outer tube 8. The light guide component is used to provide light during surgery. The light guide component includes a light guide lamp 6, which is fixedly connected to the inside of the outer tube 8. The inside of the light guide lamp 6 is fixedly connected to the guide light 3, and the outer wall of the guide light 3 is fixedly connected to the power interface 4;

[0026] Specifically, the power interface 4 is connected to the power cord, the light guide lamp 6 and the film stripper head 7 are controlled by the switch 5, and the nut sleeve 11 is rotated. The nut sleeve 11 rotates on the outer wall of the fixed rod 9 during rotation, and the outer wall of the fixed rod 9 is fixed with a clamping plate 10. The clamping plate 10 slides in the limiting groove 12 inside the nut sleeve 11 to play a limiting role, so that the nut sleeve 11 drives the outer tube 8 to move left and right and extend and retract inside the light guide head 1 during the rotation process, thereby driving the film stripper head 7 to move left and right and extend and retract, thereby achieving the effect of facilitating the extension and retraction adjustment of the film stripper head 7.

[0027] Reference Figure 1 and Figure 5 The outer wall of the light guide head 1 is fixedly connected to a first anti-slip cover 14, the outer wall of the handle 2 is fixedly connected to a second anti-slip cover 15, the interior of the first anti-slip cover 14 is provided with heat dissipation holes, the interior of the second anti-slip cover 15 is provided with heat dissipation holes, the upper surface of the second anti-slip cover 15 is fixedly connected to a first fixing clip 17, the outer wall of the first fixing clip 17 is rotatably connected to an elastic band 18, the outer wall of the second anti-slip cover 15 is slidably connected to a second fixing clip 19, the elastic band 18 is rotatably connected to the outer wall of the second fixing clip 19, the interior of the second fixing clip 19 is slidably connected to a sliding pin 20, a positioning hole 16 is provided inside the second anti-slip cover 15, the sliding pin 20 is slidably connected to the interior of the positioning hole 16, a spring 21 is provided inside the second fixing clip 19, one end of the spring 21 is fixedly connected to the interior of the second fixing clip 19, and the other end of the spring 21 is fixedly connected to the outer wall of the sliding pin 20;

[0028] Specifically, the first anti-slip cover 14 not only protects the light guide head 1, but also prevents slipping when taking it. The second anti-slip cover 15 on the outer wall of the handle 2 also protects the handle 2. During use, the hand is grasped on the outer wall of the second anti-slip cover 15. The elastic band 18 can be stuck on the outer side of the arm due to its elasticity. The tension of the elastic band 18 can be adjusted by moving the second fixing clamp 19. The second fixing clamp 19 drives the sliding pin 20 to slide and compresses the spring 21 during the sliding process. When the sliding pin 20 is stuck in the inside of the positioning hole 16, it is fixed, so as to achieve the effect of facilitating positioning, adjustment and fixation, and conveniently adjusting the tension of the elastic band 18. It can be adjusted according to usage requirements for easy operation.

[0029] Working principle: When using the film stripper to cut the optical fiber, first grasp the outer wall of the second anti-slip sleeve 15 with your hand, adjust the distance between the second fixing clamp 19 and the first fixing clamp 17 according to the size of your hand, and slide the second fixing clamp 19 to drive the sliding pin 20 to slide. During the sliding process, the sliding pin 20 is squeezed and the spring 21 is compressed. When the sliding pin 20 slides to the position of the positioning hole 16, the spring 21 resets and clamps the sliding pin 20 into the inside of the positioning hole 16 for fixation, making it easy to adjust the tension of the elastic band 18, thereby facilitating the operation during the operation. The film stripper head 7 is moved to a desired position by rotating the nut 11, thereby achieving the effect of multi-distance positioning and fixing. After the gripping is completed, the outer tube 8 is driven to extend and retract left and right inside the light guide head 1, thereby driving the film stripper head 7 to extend and retract through the extension and retraction of the outer tube 8, thereby achieving the effect of facilitating the extension and retraction adjustment, and protecting the film stripper head 7. When not in use, the outer tube 8 and the film stripper head 7 are retracted and retracted into the interior of the light guide head 1 together, and the film stripper head 7 is prevented from being exposed to the outside and contaminated with dust. The power interface 4 is connected to the power supply, and the start and stop of the light guide lamp 6 and the film stripper head 7 are controlled by the switch 5.
