[0030] In the specific implementation, through the flipping of the magnetic strip 3 and the design of the flipping mechanism, after the needle is magnetically found, the magnetic strip 3 is driven to flip through the flipping mechanism to realize the exchange of the upper and lower surfaces, so that the suture needles magnetically attracted to the bottom surface of the magnetic strip 3 are exposed to the top as the magnetic strip 3 flips, so that the suture needles are easy to observe; a pushing mechanism and a material receiving frame 10 are further provided, and the pushing mechanism is used to push and scrape the top surface of the flipped magnetic strip 3, so that the magnetically attracted suture needles can be pushed into the material receiving frame 10 to realize centralized collection. This is suitable for surgical situations that require the use of a large number of suture needles. After collection, the material receiving frame 10 is pulled out and the suture needles in the material receiving frame 10 can be poured out.

[0031] like Figure 3 and Figure 6As shown, the magnetic strip 3 includes a side strip 301 and a magnet 302, the side strips 301 are fixedly installed on the front and rear sides of the magnet 302, and the thickness of the magnet 302 is less than the thickness of the side strip 301, and the upper and lower surfaces of the magnet 302 and the side surfaces of the side strip 301 form a groove; the middle parts of both ends of the magnet 302 are fixedly installed with a rotating shaft 13, and the rotating shaft 13 is rotatably installed to the groove wall of the through groove 101.

[0032] By designing the side strip 301 and the magnet 302 at different heights, grooves are formed on both the upper and lower surfaces of the magnetic strip 3. When searching for the needle by magnetic attraction, the magnet 302 magnetically attracts the suture needle, so that the suture needle is collected at the bottom surface of the magnet 302, that is, in the groove at the bottom of the magnetic strip 3.

[0035] The docking groove 12 is used to align one side of the groove with the missing groove 1001. After the magnetic strip 3 is flipped over, the suture needle in the groove is pushed and scraped by the pushing mechanism, and can enter the receiving frame 10 through the docking groove 12 and the missing groove 1001.

[0036] like Figure 5 As shown, the pushing mechanism includes a movable bar 4 and a slider assembly 17 installed at the lower front and rear ends of the movable bar 4, two first slide grooves 7 are opened on the chassis 1, and the two first slide grooves 7 are respectively arranged in the front and rear of the through groove 101, and the slider assembly 17 is slidably installed in the first slide groove 7, and a plurality of scrapers 401 are fixedly connected to the bottom of the movable bar 4 at equal intervals along the length direction.

[0037] By driving the movable bar 4, all the scrapers 401 can be driven to move, and the scrapers 401 move in the grooves to scrape and push the suture needles therein.

[0038] The slider assembly 17 includes a sliding block 1701; a positioning hole 1704 is provided at the top of the sliding block 1701, a positioning column 1702 is connected to the positioning hole 1704 with a clearance fit, a connecting column 1703 is fixed to the top of the positioning column 1702, the connecting column 1703 is fixed to the bottom of the movable bar 4, and a spring 1705 is arranged inside the positioning hole 1704.

[0039] The slider assembly 17 can slide in the first slide groove 7 to provide guidance; at the same time, a spring 1705 is provided so that it has elastic force, and the scraper 401 is inserted into the groove. After insertion, the spring 1705 is still in a stretched state, so that the bottom of the scraper 401 presses against the groove wall to ensure the scraping effect of the scraper 401 in the groove.

[0040] One end of the spring 1705 is fixedly connected to the bottom hole wall of the positioning hole 1704 , and the other end of the spring 1705 is fixedly connected to the bottom end of the positioning column 1702 .

[0041] A first handle 5 is fixedly mounted at the top middle position of the movable bar 4 .

[0042] At least one caster 2 is installed at each of the four corners of the bottom of the outer frame 18 , and a connecting seat 8 is fixedly installed on one side of the outer frame 18 , and the connecting seat 8 is hinged to the bottom end of the hinged handle 9 .

[0043] The casters 2 can be used to move on the ground, and the hinged handle 9 can be used to push the outer frame 18 to move.

[0044] A second handle 11 is fixedly mounted on the top of the receiving frame 10 .

[0045] Instructions for use: When the entire needle finder is in use, the hinged handle 9 is held to push the device, and the casters 2 are used to move the chassis 1 on the floor of the operating room to various positions on the floor of the operating room, and the bottom surface of the magnet 302 in the magnetic attraction strip 3 is used for magnetic attraction to find the needle;

[0046] After finding the needle, the rotating rod 6 is manually rotated to drive the worm 16 to rotate. When the worm 16 rotates, all the worm wheels 15 are driven to rotate together through meshing transmission, so that the rotating shaft 13 is rotated, and the magnetic strip 3 is driven to flip and rotate. When the magnetic strip 3 flips, the side strip 301 pushes the ground, and the ground provides a reaction force. With the guidance of the slider 19 and the second slide groove 1802, the chassis 1 can automatically move up or down to ensure that the magnetic strip 3 can be flipped; the upper and lower sides of the magnetic strip 3 are adjusted, and it is flipped in place. Specifically, after flipping, one side of the groove on the top of the magnetic strip 3 is aligned with the docking groove 12, that is, it is judged that the flip is in place; after flipping, the magnetically attracted suture needle is exposed at the top of the magnetic strip 3, and then the first handle 5 is held and pushed. The sliding block 1701 slides in the first slide groove 7, so that the movable strip 4 approaches the material receiving frame 10, and the sliding block 1701 is elastically connected to the movable strip 4 through the spring 1705, such as Figure 5 As shown, the bottom of the scraper 401 contacts the top surface of the chassis 1, and the spring 1705 is in a stretched state. After the scraper 401 moves to the top of the groove, the elastic force of the spring 1705 drives the movable bar 4 downward, so that the scraper 401 is inserted into the groove. After insertion, the spring 1705 is still in a stretched state, but the stretching amount is reduced, so that the bottom of the scraper 401 presses the groove wall, and continues to push the first handle 5, driving the scraper 401 to move in the groove and the docking groove 12, and pushing the suture needle through the missing groove 1001 into the material receiving frame 10 for concentration;

[0047] Then, by pushing the first handle 5, the movable bar 4 and the scraper 401 are reset, and the scraper 401 moves to the side of the groove away from the docking groove 12, and then the first handle 5 is pulled upward to make the movable bar 4 and the scraper 401 move upward together, and then continue to push, so that the bottom of the scraper 401 contacts the top surface of the chassis 1, and the scraper 401 is not inserted into the groove, so that the push mechanism is reset. In the above process, the stretching amount of the spring 1705 is increased;

[0048] Finally, pull up the second handle 11 to remove the material receiving frame 10, then pour out the suture needles in the material receiving frame 10, and then reinstall the material receiving frame 10 into the embedding groove; after use, the magnetic strip 3 is flipped over and the upper and lower surfaces are swapped, but the upper and lower surfaces of the magnetic strip 3 are symmetrical in structure, and after swapping, there is no need to flip and reset.

[0049] The utility model is not limited to the above-mentioned embodiments. Any changes in shape or structure are within the protection scope of the utility model. The protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principle and essence of the utility model, but these changes and modifications are within the protection scope of the utility model.
