Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an anti-clogging filter for aseptic collection of synovial tissue during arthroscopic surgery. Background Technology

[0002] Arthroscopic surgery involves inserting a lenticule-equipped metal tube with illumination through a small incision into the joint cavity. The internal structure of the joint cavity is magnified on a monitor, allowing observation of lesions and their locations. Simultaneously, a comprehensive examination and cleaning of the affected area are performed under video monitoring. Synovectomy of the knee joint primarily involves removing the synovium within the knee joint under arthroscopic guidance, effectively relieving joint effusion and providing excellent treatment for joint inflammation.

[0003] The prior art CN221555976U discloses an anti-clogging filter for aseptic collection of synovial tissue during arthroscopic surgery. When collecting synovial tissue, the synovial tissue easily clogs the filter holes of the anti-clogging filter element. This results in some liquid remaining inside the anti-clogging filter element when the synovial tissue is removed for collection, which can easily cause contamination. Furthermore, when removing the synovial tissue, the anti-clogging filter element must be removed first, increasing the chance of contact with the anti-clogging filter element and hindering aseptic operation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides the following technical solution:

[0005] A filter for aseptic collection of synovial tissue during arthroscopic surgery includes an upper cover and a lower filter, wherein the upper cover and the lower filter are detachably connected.

[0006] An inlet pipe is fixedly installed on the upper cover cylinder, and an outlet pipe is fixedly installed on the lower filter cylinder;

[0007] A funnel-shaped filter screen is fixedly installed inside the lower filter cylinder. An anti-clogging cylinder is slidably installed at the bottom of the filter screen. Several through holes are opened on the outer wall and bottom of the anti-clogging cylinder. A strong magnet is installed inside the top of the anti-clogging cylinder.

[0008] An electromagnet is fixedly installed inside the upper cover cylinder. By energizing the electromagnet, the anti-blocking cylinder is attracted or repelled, thereby controlling the sliding of the anti-blocking cylinder.

[0009] Furthermore, a limiting post is fixedly installed at the bottom of the filter screen, and the anti-clogging cylinder is slidably sleeved on the limiting post and slides up and down on the limiting post.

[0010] Furthermore, a power supply and controller are fixedly installed inside the upper cover cylinder, and a charging port is provided on the outer wall of the upper cover cylinder.

[0011] Furthermore, the inlet pipe extends through the entire upper cover cylinder, and the outlet pipe is connected to the bottom of the lower filter cylinder.

[0012] Furthermore, the upper cover cylinder and the lower filter cylinder are connected by threads.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This utility model includes an upper cover cylinder and a lower filter cylinder, which are detachably connected. An inlet pipe is fixedly installed on the upper cover cylinder, and an outlet pipe is fixedly installed on the lower filter cylinder. A funnel-shaped filter screen is fixedly installed inside the lower filter cylinder. An anti-clogging cylinder is slidably installed at the bottom of the filter screen. Several through holes are formed on the outer wall and bottom of the anti-clogging cylinder, and a strong magnet is installed inside the top of the anti-clogging cylinder. An electromagnet, a power supply, and a controller are fixedly installed inside the upper cover cylinder. The controller intermittently controls the forward and reverse output current to the electromagnet, causing the electromagnet to attract or repel the strong magnet inside the anti-clogging cylinder. Due to the action of a limiting post, the anti-clogging cylinder slides up and down on the limiting post, pushing the slip film accumulated at the bottom of the filter screen upwards. This allows liquid to flow into the outlet pipe through the through holes on the outer wall and bottom of the anti-clogging cylinder, preventing a large amount of liquid from remaining on the filter screen. The detachable connection avoids contact with the filter screen, and the slip film at the bottom of the filter screen can be removed with tweezers. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] Please see Figure 1-4 A clogging-resistant filter for aseptic collection of synovial tissue during arthroscopic surgery includes an upper cover cylinder 1 and a lower filter cylinder 2, which are detachably connected. An inlet pipe 101 is fixedly mounted on the upper cover cylinder 1, and an outlet pipe 201 is fixedly mounted on the lower filter cylinder 2. A funnel-shaped filter screen 6 is fixedly mounted inside the lower filter cylinder 2, and an clogging-resistant cylinder 601 is slidably mounted at the bottom of the filter screen 6. Several through holes are formed on the outer wall and bottom of the clogging-resistant cylinder 601, and a strong magnet is installed inside the top of the clogging-resistant cylinder 601. An electromagnet 5 is fixedly mounted inside the upper cover cylinder 1. The energization of the electromagnet 5 attracts or repels the clogging-resistant cylinder 601, thereby controlling its sliding.

[0023] In this embodiment, a limiting post 602 is fixedly installed at the bottom of the filter screen 6, and the anti-clogging cylinder 601 is slidably sleeved on the limiting post 602 and slides up and down on the limiting post 602; a power supply 3 and a controller 4 are fixedly installed inside the upper cover cylinder 1, and a charging port is provided on the outer wall of the upper cover cylinder 1; the liquid inlet pipe 101 passes through the entire upper cover cylinder 1, and the liquid outlet pipe 201 is connected to the bottom of the lower filter cylinder 2; the upper cover cylinder 1 and the lower filter cylinder 2 are connected by threads.

[0024] In this embodiment, the upper cover cylinder 1 and the lower filter cylinder 2 are detachably connected. An inlet pipe 101 is fixedly installed on the upper cover cylinder 1, and an outlet pipe 201 is fixedly installed on the lower filter cylinder 2. A funnel-shaped filter screen 6 is fixedly installed inside the lower filter cylinder 2. An anti-clogging cylinder 601 is slidably installed at the bottom of the filter screen 6. Several through holes are opened on the outer wall and bottom of the anti-clogging cylinder 601, and a strong magnet is installed inside the top of the anti-clogging cylinder 601. An electromagnet 5, a power supply 3, and a controller 4 are fixedly installed inside the upper cover cylinder 1. The controller 4 intermittently controls the forward and reverse current output of the power supply 3. Electromagnet 5 is used to attract or repel the strong magnet inside the anti-clogging cylinder 601. Due to the action of the limiting post 602, the anti-clogging cylinder 601 is controlled to slide up and down on the limiting post 602, which can push the sliding membrane gathered at the bottom of the filter screen 6 upward, so that the liquid can flow into the liquid outlet pipe 201 through the through hole on the outer wall and bottom of the anti-clogging cylinder 601, thus avoiding the accumulation of a large amount of liquid on the filter screen 6. The detachable connection method can avoid contact with the filter screen 6, and the sliding membrane at the bottom of the filter screen 6 can be removed with tweezers.
