[0031] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0032] Example 1, as Figure 1 and Figure 2As shown in the figure, a needle-finding device for operating room nursing includes a housing 1. Universal wheels 2 are fixedly connected to the four corners at the lower end of the housing 1. A handle 3 is fixedly connected to the front end of the housing 1. A storage battery 4 is fixedly installed on the rear side of the lower part of the inner surface of the housing 1. A needle-finding component 5 is provided on the housing 1. A disinfection component 6 is provided on the right part of the inner surface of the housing 1.

[0033] In the process of implementation of this embodiment, the medical staff in the operating room hold the handle 3 by hand and drive the housing 1 to move on the operating room floor through the universal wheels 2. Before moving, the storage battery 4 supplies power to the needle-finding component 5, and the needle-finding component 5 searches for the surgical needles dropped on the ground. When the surgical needles are found, the infrared sensor can be used to remind the medical staff in the operating room. After the surgical needles are separated by the needle-finding component 5, they are automatically collected, and the surgical needles are disinfected by the disinfection component 6 during the collection process.

[0034] The above-mentioned storage battery 4 is a mature power energy storage technology means and device in the prior art. In this solution, its function of supplying power to the needle-finding component 5 is utilized, and its internal structure, principle and connection method will not be elaborated.

[0035] Specifically, in order to realize the search and automatic collection of surgical needles, refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 In this embodiment, the needle-finding component 5 includes a concave hole plate 51 fixedly connected to the left part of the inner surface of the housing 1. An adsorption mechanism 52 is arranged on the inner surface of the concave hole plate 51. A limiting mechanism 53 is jointly arranged on the front and rear parts of the inner surface of the housing 1. A rotating mechanism 54 and a collecting vibration mechanism 55 are arranged on the lower part of the inner surface of the housing 1. A needle feeding mechanism 56 is arranged on the lower right part of the inner surface of the housing 1.

[0036] Furthermore, refer to Figure 3 and Figure 4 In this embodiment, the adsorption mechanism 52 includes a threaded rod 522 rotatably connected to the inner surface of the housing 1. A V-shaped hole plate 521 threadedly connected to the outer surface of the threaded rod 522 and slidably connected to the inner surface of the concave hole plate 51. A servo motor 523 is fixedly installed at the front end of the housing 1. The output end of the servo motor 523 is fixedly connected to the front end of the threaded rod 522 through a coupling. A slide rod 524 is jointly slidably connected to the inner surfaces of the concave hole plate 51 and the V-shaped hole plate 521. An electromagnet 525 is rotatably connected to the inner surface of the slide rod 524.

[0037] Furthermore, refer to Figure 3 and Figure 5, in this embodiment, the limiting mechanism 53 includes a rectangular rod 531 fixedly connected to the front and rear inner surfaces of the housing 1. A slider 532 is slidably connected to the outer surface of the rectangular rod 531, and a round rod 533 slidably connected to the sliding rod 524 is fixedly connected to the lower end of the slider 532.

[0038] During the implementation process, the output end of the servo motor 523 drives the threaded rod 522 to rotate through a coupling. Since the V-shaped orifice plate 521 is threadedly connected to the threaded rod 522, the V-shaped orifice plate 521 moves backward on the inner surface of the concave orifice plate 51. The sliding rod 524 is slidably connected to the V-shaped orifice on the inner surface of the V-shaped orifice plate 521 and the concave orifice of the concave orifice plate 51. Under the action of the V-shaped orifice plate 521, the sliding rod 524 continuously moves upward at the bottom of the front section of the concave orifice plate 51, causing the sliding rod 524 to slide upward on the outer surface of the round rod 533. When the sliding rod 524 moves to the horizontal position of the concave orifice plate 51, at this time, the sliding rod 524 is located at the intersection of the V-shaped orifice plate 521. At this time, the sliding rod 524 will move backward, causing the slider 532 to move backward on the rectangular rod 531. When it moves to the rearmost horizontal position of the concave orifice plate 51, at this time, the sliding rod 524 will slide downward on the inner surface of the concave orifice plate 51 under the action of the V-shaped orifice plate 521, causing the electromagnet 525 to extend into the inner cavity of the housing 1. The electromagnet 525 adsorbs the surgical needle through its magnetic attraction ability. After the electromagnet 525 adsorbs the surgical needle, it can be sensed by two vertically distributed infrared sensors, and the medical staff will be reminded that the surgical needle has been found, realizing the automatic adsorption of the surgical needle, saving the time for the medical staff to search for the surgical needle, and improving the surgical efficiency.

[0039] The above-mentioned electromagnet 525 is a mature magnetic attraction technology means and device in the prior art. In this solution, its function of generating magnetic force to adsorb the surgical needle is utilized, and its internal structure, principle, and connection method will not be elaborated.

[0040] The above-mentioned infrared sensor is a mature sensor in the prior art. In this solution, its internal structure, principle, and connection method will not be elaborated.

[0041] Further, referring to Figure 3 and Figure 6 , in this embodiment, the rotating mechanism 54 includes a first rack 541 fixedly connected to the lower inner surface of the housing 1. A gear 542 meshing with the first rack 541 is fixedly connected to the outer surface of the electromagnet 525.

[0042] Further, referring to Figure 3 、 Figure 7 and Figure 8, in this embodiment, the collection vibration mechanism 55 includes a circular ring block 551 fixedly connected to the lower part of the inner surface of the outer shell 1. A conical frame 552 is fixedly connected to the inner surface of the circular ring block 551. A toothed ring 553 is rotatably connected to the upper end of the circular ring block 551. A second rack 554 meshingly connected to the toothed ring 553 is fixedly connected to the right end of the V-shaped orifice plate 521. A fixed ring 555 is fixedly connected to the inner surface of the circular ring block 551. An arc-shaped block rod 557 is slidably connected to the inner surface of the fixed ring 555 in an annular and equidistant distribution. A first spring 558 is sleeved on the outer surface of several arc-shaped block rods 557. Both ends of the first spring 558 are fixedly connected to the lower end of the fixed ring 555 and the upper end of the arc-shaped block on the arc-shaped block rod 557 respectively.

[0043] During the implementation process, after the surgical needle is adsorbed, the reverse rotation of the servo motor 523 drives the electromagnet 525 to move forward through the cooperation of the V-shaped orifice plate 521 and the concave orifice plate 51. During the horizontal movement, the gear 542 meshes with the first rack 541, and then drives the electromagnet 525 to rotate on the inner surface of the slide rod 524. The lower end of the electromagnet 525 is in close contact with the inner surface of the conical frame 552 through a scraper. During the rotation of the electromagnet 525, the adsorbed surgical needle will be scraped off by the scraper, avoiding the residual magnetic force of the surgical needle after the electromagnet 525 is turned off, which makes the surgical needle unable to fall automatically. The surgical needle will fall into the inner cavity of the conical frame 552 under the action of gravity. After the electromagnet 525 adsorbs the surgical needle, it can automatically release it. Through the action of the scraper, the surgical needle is successfully removed, avoiding the problem that the surgical needle cannot fall automatically due to magnetic force residue, not only improving the cleanliness and operability of the surgical needle, but also reducing the intervention of medical staff and improving the working efficiency of the operating room.

[0044] Secondly, during the forward movement of the V-shaped orifice plate 521, it will drive the second rack 554 and the toothed ring 553 to be meshingly connected, causing the toothed ring 553 to rotate on the upper end of the circular ring block 551. During the rotation of the arc-shaped block 556, it will gradually squeeze the arc-shaped block rod 557, and the first spring 558 is in a compressed state. The arc-shaped block rod 557 will slide upward on the inner surface of the fixed ring 555, and the upper end of the arc-shaped block rod 557 will push against the conical frame 552, preventing the surgical needle falling into the conical frame 552 from getting stuck in the inner cavity of the conical frame 552, ensuring that the surgical needle will not get stuck or detained during the falling process, thereby improving the smooth release of the surgical needle, effectively avoiding operation delays caused by jams, enhancing the efficiency and safety of the operation, and reducing the extra workload of medical staff.

[0045] Further, refer to Figure 3 and Figure 9, in this embodiment, the needle feeding mechanism 56 includes a cylinder 561 fixedly connected to the inner surface of the housing 1. A circular block 562 is fixedly connected to the inner surface of the cylinder 561. A first piston rod 563 is slidably connected to the inner surface of the circular block 562. A placing block 564 is fixedly connected to the lower part of the inner surface of the housing 1. A second piston rod 565 is slidably connected to the inner surface of the placing block 564. The inner surfaces of the placing block 564 and the circular block 562 are connected by a pipeline. A collecting block 566 is fixedly connected to the left end of the second piston rod 565. A second spring 567 is sleeved on the outer surface of the first piston rod 563. The two ends of the second spring 567 are respectively fixedly connected to the upper part of the inner surface of the circular block 562 and the piston on the first piston rod 563.

[0046] As can be seen from the above, the output needles collected by the conical frame 552 will slide through the pipeline into the inner cavity of the collecting block 566. When the electromagnet 525 returns to the initial state under the cooperation of the concave orifice plate 51 and the V-shaped orifice plate 521, at this time, the electromagnet 525 can enter the inner cavity of the cylinder 561 and squeeze the first piston rod 563 to move downward. The second spring 567 is in a compressed state. The first piston rod 563 will squeeze the hydraulic oil in the circular block 562 into the inner cavity of the placing block 564 through the pipeline, and then push the second piston rod 565 to move forward on the inner surface of the placing block 564, pushing the collecting block 566 to extend out of the inner cavity of the housing 1, thereby driving medical staff to take the surgical needles in the collection frame of the collecting block 566, avoiding the complexity and time delay of manual operation, which not only improves the efficiency of surgical needle collection, reduces unnecessary intervention, optimizes the operation process in the operating room, ensures the smooth progress of the operation, and improves the overall work efficiency and safety.

[0047] Embodiment 2. On the basis of Embodiment 1, this embodiment adds a disinfection component 6 for disinfecting the found needles, so as to achieve the purpose of disinfecting the found needles.

[0048] Specifically, in order to disinfect the found needles, refer to Figure 3 and Figure 10 , in this embodiment, the disinfection component 6 includes an inclined block 61 fixedly connected to the upper part of the outer surface of the second piston rod 565. An extrusion mechanism 62 and a spraying mechanism 63 are arranged on the right part of the inner surface of the housing 1.

[0049] Furthermore, refer to Figure 3 and Figure 10 , in this embodiment, the extrusion mechanism 62 includes a storage box 621 fixedly connected to the right part of the inner surface of the housing 1. A rectangular block 622 is fixedly connected to the left end of the storage box 621. A third piston rod 623 is slidably connected to the inner surface of the rectangular block 622. A third spring 624 is sleeved on the outer surface of the third piston rod 623. The two ends of the third spring 624 are respectively fixedly connected to the lower part of the inner surface of the rectangular block 622 and the piston on the third piston rod 623. The inner surface of the storage box 621 is connected to the inner surface of the rectangular block 622.

[0050] Further, referring to Figure 3 and Figure 10 In this embodiment, the spraying mechanism 63 includes a spraying pipe 631 fixedly connected to the inner surface of the rectangular block 622. A number of spray heads 632 are fixedly connected to the inner surface of the spraying pipe 631 at equal linear distances. One end of the spraying pipe 631 and the inner surface of the storage tank 621 and the inner surface of the rectangular block 622 where they communicate are both fixedly connected with one-way valves 633.

[0051] During the implementation process, when the second piston rod 565 moves forward, the inclined block 61 fixedly connected to its outer surface will squeeze the third piston rod 623 to slide upward on the inner surface of the rectangular block 622 during the forward movement, and the third spring 624 is in a compressed state, so that the disinfectant liquid in the inner cavity of the rectangular block 622 can enter the spraying pipe 631 through the one-way valve 633 on the spraying pipe 631 and be sprayed out through the spray heads 632 to automatically disinfect the surgical needles. It can accurately disinfect the surgical needles, ensure that the surgical needles are thoroughly disinfected, reduce omissions in manual operations, improve the hygienic safety of the surgical needles, reduce the risk of cross-infection, and also ensure the efficiency and consistency of the disinfection process, and improve the safety standards of the surgical environment.

[0052] Secondly, after the inclined block 61 moves away from the third piston rod 623, the third piston rod 623 will reset under the action of the third spring 624, and through the one-way valve 633 connected to the inner surface of the storage tank 621 and the inner surface of the rectangular block 622 where they communicate, under the action of the positive and negative pressure difference, the disinfectant liquid in the storage tank 621 is introduced into the inner cavity of the rectangular block 622 again.

[0053] The two one-way valves 633 mentioned above are mature one-way control components in the prior art. In this solution, their function of controlling the flow direction of the liquid is utilized, and it is ensured that the control directions of the two one-way valves 633 are opposite. The internal structure, principle and connection method will not be elaborated further.

[0054] Workflow: During use, the adsorption mechanism 52 and the limiting mechanism 53 cooperate to search for and adsorb the surgical needles on the operating room floor. After the search is completed, the adsorbed needles are detached and collected under the combined action of the rotation mechanism 54 and the collection vibration mechanism 55. Subsequently, the surgical needles are automatically fed by the needle feeding mechanism 56, and during the needle feeding process, the surgical needles are disinfected under the combined action of the extrusion mechanism 62 and the spraying mechanism 63.
