Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a flushing device for shoulder arthroscopic surgery. Background Art

[0002] The irrigation device for shoulder arthroscopic surgery is a device used to inject irrigation fluid into the joint cavity during arthroscopic surgery to clean and flush foreign matter, diseased tissue, blood, tissue fluid and excised tissue fragments in the joint, thereby keeping the surgical area clean and providing a clear surgical field of view.

[0003] When flushing the joint cavity, the existing flushing device for shoulder arthroscopy surgery drives the gear to rotate through the reduction motor, thereby driving the tooth plate to move, and then driving the pressure roller to move, so that the outer surface of the pressure roller is tightly attached to the outer surface of the flushing liquid bag and moves. By squeezing the flushing liquid bag, the liquid in the flushing liquid bag is injected into the joint cavity through the catheter. When the flushing liquid bag needs to be placed and removed, the pressure roller needs to be slightly moved upward to separate the pressure roller from the flushing liquid bag before the flushing liquid bag can be placed and removed. Although this device can provide sufficient pressure for flushing, when the flushing liquid bag needs to be placed and removed, the user needs to slightly move the pressure roller upward. Therefore, it is not very convenient when placing and removing. Utility Model Content

[0004] The cam is secured to the interior of the housing and has a shaft supported by the guide rail, the guide rail being fixedly secured to the interior of the housing and slidably connected to the gear train.

[0005] As an improvement of the above technical solution, a spring is wound around the surface of the moving rod, one end of the spring is fixedly connected to the connecting plate, and the other end of the spring is fixedly connected to the pressure roller frame.

[0006] As an improvement of the above technical solution, the upper end of the moving rod is fixedly connected to a sleeve frame, and the interior of the shell is slidably connected to a sliding plate, which passes through the sleeve frame and is slidably connected to the sleeve frame.

[0007] As an improvement of the above technical solution, one end of the pressure roller frame is fixedly connected to an arc-shaped baffle, and the arc-shaped baffle is arranged corresponding to the pressure roller.

[0008] As an improvement to the above technical solution, a layer of anti-slip grooves is provided on the inner bottom surface of the shell.

[0009] Beneficial effects of the utility model:

[0010] Since the shape of the slide is a broken line, the pressure roller is initially located at the highest point of the slide, so that the pressure roller maintains a distance of one end from the inner bottom surface of the shell, which makes it easy for the user to place the flushing liquid bag. When the pressure roller completes the extrusion work, the sliding rod slides inside the slide, so that the pressure roller rises to the highest point of the slide again. At the same time, the moving rod slides upward relative to the connecting plate, so that the pressure roller maintains a distance of one end from the inner bottom surface of the shell, which makes it easy for the user to remove the flushing liquid bag, thereby improving the ease of use of this mechanism.

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] See also Figure 1-5 The utility model provides a technical solution: a flushing device for shoulder arthroscopy surgery, comprising a shell 1, a rectangular opening 2 and a circular opening 3 are opened on the surface of the shell 1, a baffle 4 is slidably connected to the end surface of the shell 1, a flushing mechanism 5 is provided inside the shell 1, the flushing mechanism 5 includes a reduction motor 51, a reduction motor 51 is installed inside the shell 1, the output end of the reduction motor 51 is connected to a gear 52, a guide rail 53 is fixedly connected to the inside of the shell 1, a slider 54 is slidably connected to the inside of the guide rail 53, and one end of the slider 54 is fixedly connected to a connecting rod. The connecting rod 55 has a tooth plate 56 fixedly connected to one end of the connecting rod 55, which meshes with the gear 52. The lower end of the tooth plate 56 is fixedly connected to a connecting plate 57. The surface of the connecting plate 57 is slidably connected to a moving rod 58 that passes through it. The moving rod 58 is rotatably connected to a pressure roller 591 through a pressure roller frame 59 set at its lower end. The rotating shaft end of the pressure roller 591 is rotatably connected to a sliding rod 592. The interior of the shell 1 is fixedly connected to a slideway 593. One end of the sliding rod 592 extends to the interior of the slideway 593 and is slidably connected to the slideway 593.

[0019] In this embodiment, first slide the baffle 4 upward and separate the baffle 4 from the shell 1, then put the washing liquid bag into the shell 1 so that one end of the washing liquid bag corresponds to the pressure roller 591, and at the same time, pass the catheter of the washing liquid bag through the circular opening 3, then reset the baffle 4, and then start the reduction motor 51, thereby driving the gear 52 to rotate, and then driving the tooth plate 56 to move, and at the same time the tooth plate 56 passes through the rectangular opening 2, thereby driving the slider 54 to slide inside the guide rail 53 through the connecting rod 55, and at the same time the connecting plate 57 moves, thereby driving the pressure roller 591 to roll on the surface of the washing liquid bag through the moving rod 58 and the pressure roller frame 59. As the pressure roller 591 moves, The sliding rod 592 is driven to slide inside the slide 593. Since the shape of the slide 593 is a broken line, the pressure roller 591 is initially located at the highest point of the slide 593, so that the pressure roller 591 maintains a distance of one end from the inner bottom surface of the shell 1, so that it is convenient for the user to place the flushing liquid bag. When the pressure roller 591 completes the extrusion work, the sliding rod 592 slides inside the slide 593, so that the pressure roller 591 rises to the highest point of the slide 593 again. At the same time, the moving rod 58 slides upward relative to the connecting plate 57, so that the pressure roller 591 maintains a distance of one end from the inner bottom surface of the shell 1, so that it is convenient for the user to remove the flushing liquid bag, thereby improving the convenience of use of this mechanism.

[0020] Specifically, a spring 594 is wound around the surface of the moving rod 58 , one end of the spring 594 is fixedly connected to the connecting plate 57 , and the other end of the spring 594 is fixedly connected to the pressure roller frame 59 .

[0021] In this embodiment, when the sliding rod 592 slides on the inclined portion of the slide 593, the moving rod 58 slides up and down. By setting the spring 594, the elastic force of the spring 594 can make the moving rod 58 rise and fall more stably, thereby making this mechanism more stable when working.

[0022] Specifically, the upper end of the moving rod 58 is fixedly connected to the sleeve frame 595 , and the interior of the housing 1 is slidably connected to a sliding plate 596 . The sliding plate 596 passes through the sleeve frame 595 and is slidably connected to the sleeve frame 595 .

[0023] In this embodiment, when the pressure roller 591 rolls on the surface of the flushing liquid bag, the moving rod 58 drives the sleeve frame 595 to slide on the surface of the sliding plate 596. The provided sliding plate 596 can stabilize the flushing liquid bag, thereby improving the squeezing effect of this mechanism on the flushing liquid bag. When the pressure roller 591 is in the ascending stage, the sleeve frame 595 drives the sliding plate 596 to slide upward inside the shell 1, thereby increasing the distance between the sliding plate 596 and the bottom of the shell 1, thereby facilitating the user to place and remove the flushing liquid bag.

[0024] Specifically, one end of the pressure roller frame 59 is fixedly connected to an arc-shaped baffle 597 , and the arc-shaped baffle 597 is arranged corresponding to the pressure roller 591 .

[0025] In this embodiment, the arc-shaped baffle 597 is provided to prevent the pressing roller 591 from rolling the partially squeezed flushing liquid bag into the interior of the pressing roller 591 .

[0026] Specifically, a layer of anti-slip grooves 6 is provided on the inner bottom surface of the housing 1 .

[0027] In this embodiment, the anti-slip grooves 6 are provided to increase the friction between the housing 1 and the flushing liquid bag, and the flushing liquid bag can be better stabilized in conjunction with the sliding plate 596 .

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
