Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a sterile protective sleeve for surgical robots. Background Technology

[0002] Laparoscopy is used to assist surgeons in abdominal surgery. The camera and fiber optic cables in the laparoscopic imaging system need to be connected to the laparoscope lens inserted into the abdominal cavity. While the laparoscope lens can be sterilized, the connected camera and fiber optic cables cannot. Therefore, the portion of the components entering the surgical environment must be encased in a sterile protective sleeve to ensure a sterile surgical environment. This sterile protective sleeve is 1.5-2 meters long.

[0003] Existing protective sleeves are generally flat and straight strips that are stored after being rolled up. When using them, the rolled-up protective sleeve must first be unrolled, then the opening of the bag must be located and the protective sleeve opened, and finally the protective sleeve is placed on the optical fiber and camera. Because the protective sleeve itself is long, this type of protective sleeve is time-consuming and laborious to operate, and it is difficult for one person to complete the operation independently, making it inconvenient.

[0025] This embodiment proposes a sterile protective sleeve for surgical robots, such as... Figures 1 to 6 As shown, the protective sleeve 10 is a cylindrical protective sleeve that can be compressed and folded along the axial direction. The upper and lower ends of the protective sleeve 10 are provided with elastic bands 11, and the outer circumference of the elastic bands 11 is provided with a tightening component. The tightening component is used to tighten the opening of the elastic bands 11, thereby tightly fitting the elastic bands 11 to the equipment. Inside the protective sleeve 10, there are pull ropes 15 arranged in a ring along its axial direction. One end of the pull rope 15 is fixed inside the protective sleeve 10, and the other end of the pull rope 15 extends out of the protective sleeve 10 and extends in the vertical direction.

[0026] The fastening assembly includes Velcro 22 and Velcro 23 sewn onto the outer periphery of the elastic band 11. Velcro 22 and Velcro 23 can be glued together. When installing the protective cover 10 on the equipment, the operator opens the protective cover 10 by hand and puts the protective cover 10 on the equipment. At the same time, the elastic band 11, which extends out of the protective cover 10, is fixed to the equipment by the Velcro 22 and Velcro 23.

[0027] Please see Figure 1-6 The protective sleeve 10 has mounting rings 12 spaced vertically on its outer circumference. A slider 13 is slidably mounted on the mounting ring 12. A fixing block 14 is fixedly mounted on the mounting ring 12. An elastic element, which is a tension rope 24, is provided at the far end of the fixing block 14 and the slider 13. The elastic element is used to connect the fixing block 14 and the slider 13 together. A clamping component is provided at the near end of the fixing block 14 and the slider 13. The clamping component is used to clamp the fixing block 14 and the slider 13 together, thereby clamping the protective sleeve 10 onto the equipment and preventing the protective sleeve 10 from shifting during equipment use.

[0028] The clamping assembly includes a fixing plate 16 fixedly mounted on the slider 13. The slider 13 is provided with first ratchet teeth 17 spaced back and forth. The fixing block 14 is provided with a through groove that runs through the front and back. The fixing block 14 is provided with a receiving groove inside, which is connected to the through groove. A second ratchet tooth 18 that matches the first ratchet tooth 17 is slidably installed inside the through groove. A driving member is provided inside the receiving groove. The driving member is connected to the second ratchet tooth 18. The driving member is used to bring the second ratchet tooth 18 into the receiving groove, so that the first ratchet tooth 17 can freely enter and exit the through groove, and the first ratchet tooth 17 and the second ratchet tooth 18 are no longer jammed.

[0029] The driving component includes a driving block 19 that is slidably provided with a receiving groove inside, a sliding groove that is connected to the receiving groove on a fixed block 14, a moving block 20 that is slidably provided inside the sliding groove and connected to the driving block 19, a reset component that is provided inside the receiving groove and connected to the driving block 19, the reset component being used to push the second ratchet 18 out of the receiving groove through the driving block 19, so that the second ratchet 18 and the first ratchet 17 are re-engaged, the reset component being a spring 21.

[0030] After the protective cover 10 is placed on the equipment, the elastic band 11 is tightly attached to the equipment using the Velcro 22 and Velcro 23. At the same time, the slider 13 is slidable, and the first ratchet 17 on the slider 13 enters the through groove. The first ratchet 17 can push the second ratchet 18 into the receiving groove, while compressing the spring 21. When the first ratchet 17 and the second ratchet 18 are no longer engaged, the spring 21 drives the second ratchet 18 out of the receiving groove through the drive block 19, so that the first ratchet 17 and the second ratchet 18 re-engage. The first ratchet 17 and the second ratchet 18 make the slider 13 move only towards the fixed block 14 and not away from the fixed block 14. The tension rope 24 can tighten the protective cover 10, so that the protective cover 10 can be tightly attached to the equipment, preventing the protective cover 10 from shifting during equipment use and thus interfering with the equipment.

[0031] Please see Figure 1-6 Working principle: When in use, the operator opens the protective cover 10 by hand and puts the protective cover 10 on the equipment. At the same time, the elastic band 11 of the pull rope 15 extending outside the protective cover 10 is fixed to the equipment by the Velcro 22 and Velcro 23.

[0032] The elastic band 11 is tightly attached to the device using Velcro 22 and Velcro 23. Simultaneously, the slider 13 is slidable, and the first ratchet 17 on the slider 13 enters the through groove. The first ratchet 17 can push the second ratchet 18 into the receiving groove, while compressing the spring 21. When the first ratchet 17 and the second ratchet 18 are no longer engaged, the spring 21 drives the second ratchet 18 out of the receiving groove through the drive block 19, so that the first ratchet 17 and the second ratchet 18 re-engage. The first ratchet 17 and the second ratchet 18 ensure that the slider 13 can only move towards the fixed block 14 and cannot move away from the fixed block 14. The tension rope 24 can tighten the protective sleeve 10, so that the protective sleeve 10 can be tightly attached to the device, preventing the protective sleeve 10 from shifting during device use and thus interfering with the device.

[0033] When the protective cover 10 needs to be removed, pull the moving block 20. The moving block 20 drives the second ratchet 18 to move towards the receiving groove through the drive block 19. At the same time, the spring 21 is compressed, so that the first ratchet 17 can disengage from the through groove. Then, the operator first loosens the Velcro 22 and Velcro 23 on the elastic band 11 at the inner end of the pull rope 15 inside the protective cover 10. Then, the operator pulls the pull rope 15 by hand. At this time, the pull rope 15 can drive the protective cover 10 to move in the direction where the pull rope 15 extends out of the protective cover 10, thereby stretching and folding the protective cover 10. Finally, loosen the Velcro 22 and Velcro 23 on the elastic band 11 at the outer end of the pull rope 15 outside the protective cover 10.
