Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an operating room nursing needle finder. Background Technology

[0002] During surgery, ensuring the accurate counting and retrieval of all instruments used is crucial. This is especially true for small and critical items such as surgical needles, as any loss can lead to serious medical accidents, including but not limited to the retention of foreign bodies in the body requiring additional surgery. Traditional manual retrieval methods are not only time-consuming but also prone to human error. To address these issues, a specially designed operating room needle finder has been developed to improve safety and efficiency during surgery.

[0003] Patent publication number CN222091749U discloses an operating room needle finder. It includes a main frame, with connecting brackets fixedly connected to both sides of the back of the main frame. A rotating groove is fixedly connected to one side of the top of each connecting bracket. This invention allows the electromagnetic chuck to rotate upwards after absorbing the suture needle through the rotatable connection between the main frame and the connecting frame. The needle finder's length can be adjusted according to needs via buttons and holes, making it easier to insert the electromagnetic chuck into gaps for needle retrieval. However, since it mainly relies on the electromagnetic chuck to absorb and retrieve suture needles, and not all suture needles are made of magnetic materials such as iron, it can easily lead to missed needles for non-magnetic needles, thus its practicality needs improvement. Therefore, we designed an operating room needle finder to achieve comprehensive needle retrieval in the operating room. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, an operating room needle finder is provided to reduce the occurrence of missed needles in the operating room and improve the needle finding effect.

[0005] The technical solution of this utility model is as follows: a needle finder for operating room care, comprising a mounting plate, which serves as the assembly carrier for the needle finder. A caster wheel is mounted on the rear side of the bottom surface of the mounting plate. The front part of the mounting plate is a downwardly inclined plate, and at least two caster wheels are mounted on the front end of the bottom surface of the front part of the mounting plate. It also includes mounting blocks, sliding blocks, rollers, adhesive fabric, and springs. Mounting blocks are symmetrically fixedly mounted on both sides of the middle portion of the mounting plate. Sliding blocks are slidably mounted on the bottom of both mounting blocks. The sliding blocks are connected to guide rods and... The mounting blocks on the sides slide together, and a roller is rotatably mounted between the two sliding blocks. The outer surface of the roller is covered with adhesive cloth, which has a certain degree of stickiness. The adhesive cloth is used to stick needles and other impurities on the ground. A scraping groove is opened on the inclined surface of the front plate of the mounting plate. A spring is provided between the mounting block and the corresponding sliding block. The spring acts on the roller through the sliding block, so that the adhesive cloth on the roller adheres to the scraping groove of the inclined plate at the front of the mounting plate. The lowest surface of the adhesive cloth on the roller is flush with the bottom surface of the first and second universal wheels.

[0006] In one embodiment, the adhesive cloth is attached to the surface of the roller by an adhesive, detachable winding, which allows for easy installation and removal from the roller surface, thus facilitating cleaning and maintenance of the adhesive cloth.

[0007] In one embodiment, a collection frame is installed on the top surface of the front part of the mounting plate. The opening of the collection frame is inclined and fits against the bottom of the downwardly inclined front part of the mounting plate. The collection frame is located below the scraping opening of the mounting plate and is used to collect needles and other substances scraped off by the scraping opening.

[0008] In one embodiment, an electromagnet is also included. An electromagnet is installed on the bottom surface of the front plate of the mounting plate. The mounting plate is located on the front side of the roller. The electromagnet is used to pre-attract magnetically attracted metal needles and other substances on the needle-finding surface. In conjunction with the adhesive cloth on the roller rolling on the ground, any missed non-magnetic substances and magnetically attracted metal needles are further adhered and cleaned by the adhesive cloth, thereby improving the needle-finding effect of the needle finder.

[0009] In one embodiment, a metal detector is also included. The metal detector is mounted on the rear bottom surface of the mounting plate and is located on the rear side of the roller. The metal detector is used to detect whether there is metal on the ground after passing through. The metal detector has a built-in alarm to remind the user whether a metal needle has been missed when it is missed.

[0010] In one embodiment, a guide frame is fixedly installed on the rear side of the top surface of the mounting plate. The guide frame consists of two vertically oriented branch pipes. A sliding frame is slidably installed on the guide frame. The sliding frame facilitates user operation and allows the needle finder to be moved on the ground for needle finding operations, enabling the entire needle finder to reach into difficult-to-pass needle finding corners.

[0011] Compared with the prior art, the present invention has the following advantages: 1. This utility model uses a combination of adhesive cloth and electromagnet to not only adhere to needles and other impurities of various materials, but also to pre-adsorb magnetically adsorbable metal substances on the ground, thereby effectively reducing the possibility of omissions. It is also equipped with a metal detector and an alarm, which can detect whether there are any undiscovered metal needles on the ground in the final stage and promptly remind the user when omissions are found.

[0012] 2. The mounting plate of this utility model is provided with a collection frame located below the scraping nozzle at the front. When the adhesive cloth rolls, the attached needles will be scraped off and slide into the collection frame when passing through the scraping nozzle, simplifying the needle collection process.

[0013] 3. The adhesive cloth of this utility model adopts a design that allows for detachable winding and assembly onto the roller surface, making it convenient for users to clean and maintain the equipment, thereby improving its practicality and efficiency. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] An operating room needle finder, such as Figures 1-4 As shown, the device includes a mounting plate 1, which serves as the assembly carrier for the needle finder. A caster wheel 2 is mounted on the rear side of the bottom surface of the mounting plate 1. The front part of the mounting plate 1 is a downwardly inclined plate, and at least two caster wheels 3 are mounted on the front end of the bottom surface of the front plate. It also includes mounting blocks 5, sliding blocks 6, rollers 7, adhesive cloth 8, and springs 9. Mounting blocks 5 are symmetrically fixed on both sides of the middle section of the mounting plate 1. Sliding blocks 6 are slidably mounted on the bottom of each mounting block 5. The sliding blocks 6 slide against the corresponding mounting blocks 5 on the same side via guide rods. A roller 7 is rotatably mounted between the two sliding blocks 6. Adhesive cloth 8 is provided on the outer surface of the roller 7. The adhesive cloth 8 has a certain degree of stickiness and is used to adhere needles and other impurities to the ground. An opening is made on the inclined surface of the front plate of the mounting plate 1. There is a scraping opening 121. A spring 9 is provided between the mounting block 5 and the corresponding sliding block 6. The spring 9 acts on the roller 7 through the sliding block 6, so that the adhesive cloth 8 on the roller 7 adheres to the scraping opening 121 of the front inclined plate of the mounting plate 1. The lowest point of the adhesive cloth 8 on the roller 7 is flush with the bottom surface of the universal wheel 1 2 and universal wheel 2 3. By pushing the mounting plate 1, the universal wheel 1 2 and universal wheel 2 3 cooperate to make the adhesive cloth 8 on the roller 7 adhere to the ground of the needle search and roll. The adhesive cloth 8 can adhere to needles and impurities of various materials on the ground. When the needles adhered to the surface of the adhesive cloth 8 scrape the scraping opening 121 on the mounting plate 1, the needles will be scraped off by the scraping opening 121 and slide onto the front inclined plate of the mounting plate 1. This makes it easier to find needles on the ground and reduces the possibility of missing needles when using magnetic needle search.

[0021] like Figure 2 As shown, the adhesive cloth 8 is attached to the surface of the roller 7 by adhesive detachable winding. The adhesive cloth 8 can be easily installed and removed from the surface of the roller 7, which facilitates cleaning and maintenance of the adhesive cloth 8.

[0022] like Figure 1 and Figure 2 As shown, a collection frame 12 is installed on the top surface of the front part of the mounting plate 1. The opening of the collection frame 12 is inclined and attached to the bottom of the downwardly inclined front part of the mounting plate 1. The collection frame 12 is located below the scraping opening 121 of the mounting plate 1. The collection frame 12 is used to collect needles and other substances scraped off by the scraping opening 121.

[0023] like Figure 3As shown, it also includes an electromagnet 11. The electromagnet 11 is installed on the bottom surface of the front plate of the mounting plate 1. The mounting plate 1 is located on the front side of the roller 7. The electromagnet 11 is used to pre-attract magnetic metal needles and other substances that exist on the needle-finding ground. In conjunction with the adhesive cloth 8 on the roller 7 rolling on the ground, the non-magnetic substances and magnetic metal needles that are missed are further adhered and cleaned by the adhesive cloth 8, thereby improving the needle-finding effect of the needle finder.

[0024] like Figure 1 and Figure 3 As shown, it also includes a metal detector 10. The metal detector 10 is installed on the rear bottom surface of the mounting plate 1. The metal detector 10 is located on the rear side of the roller 7. The metal detector 10 is used to finally detect whether there is metal on the ground. The metal detector 10 has a built-in alarm to remind the user whether a metal needle has been missed when a metal needle is missed.

[0025] like Figure 1 and Figure 4 As shown, a guide frame 4 is fixedly installed on the rear side of the top surface of the mounting plate 1. The guide frame 4 consists of two vertically oriented branch pipes. A pusher frame 13 is slidably installed on the guide frame 4. The pusher frame 13 facilitates user operation and pushes the needle finder on the ground to perform needle finding operations, so that the entire needle finder can reach into needle finding corners that are difficult to pass through.

[0026] When using this needle finder to locate needles on the operating room floor, the operator holds the pusher 13 and, by adjusting the height and angle of the guide frame 4, smoothly pushes the device into the area of ​​the operating room floor that needs cleaning. After activation, the electromagnet 11 located below the front of the mounting plate 1 is energized, generating a strong magnetic field that preferentially attracts scattered ferromagnetic surgical needles or metal debris, reducing the workload of the subsequent adhesive cloth 8. At the same time, the roller 7, under the elastic pressure of the spring 9, adheres to the scraping edge 121 of the mounting plate 1. With the coordinated rolling of the universal wheels 2 and 3, the roller 7, whose surface is covered with high-adhesion medical-grade silicone adhesive cloth 8, rotates at a uniform speed. During the rolling of the adhesive cloth 8 on the roller 7 on the floor, non-magnetic needles (such as some alloy or plastic suture needles), tissue debris, hair, and other impurities are removed. The material is captured by adhesion. When the roller 7 rotates to the metal scraper 121 on the inclined plate at the front of the mounting plate 1, the cutting structure at the edge of the scraper 121 contacts the surface of the adhesive cloth 8 at a specific cutting angle. The tension change of the adhesive cloth 8 during its rewinding precisely peels off the adhesive. The scraped-off needle slides along the inclined plate into the collection frame 12 on the mounting plate 1 for collection. During the movement of the equipment, the broadband metal detector 10 on the mounting plate 1 scans the cleaned area in pulse mode. If a residual metal signal is detected, an audible and visual alarm is immediately triggered to prompt a re-inspection. After the entire area is covered, the magnetic needle attracted by the electromagnet 11 can be automatically detached by power failure and is easy to collect later. This, together with the non-magnetic needles collected by the adhesive cloth 8, forms a double insurance, thereby improving the needle recovery rate in the operating room.

[0027] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
