Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a needle locator for operating rooms. Background Technology

[0002] In the operating room of a hospital, medical staff work under great pressure every day. In order to ensure the safety of patients, the entire operation must strictly follow the operating procedures to ensure that there are no hidden dangers in every step before, during and after the operation. Therefore, an inventory of instruments must be carried out after each operation to check whether all the instruments used have been retrieved. The existing needle locator in the operating room uses a magnet to directly attract and locate the needle. If the needle is attracted to the needle locator, it usually needs to be removed by hand. Moreover, since medical staff are mostly in full protective gear in the operating room, it is inconvenient for them to remove the needle. In order to solve the existing problems, a needle locator for the operating room is proposed. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of manually removing needles adsorbed on needle locators, and the fact that general needle locators do not have a folding structure, resulting in them occupying a large space when placed, thus reducing the operating space in the operating room. Therefore, this invention proposes a needle locator for the operating room.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design an operating room needle locator, comprising a housing with a needle locating port at the bottom, a servo motor fixedly mounted at the top of the housing, a transmission gear set fixedly mounted at the end of the transmission shaft of the servo motor, multiple sets of magnetic rollers rotatably mounted inside the housing, a driven wheel rotatably mounted inside the housing, a transmission column rotatably mounted inside the housing, one end of the transmission column penetrating the housing and fixedly connected to the transmission gear set, a transmission magnetic roller fixedly mounted on the outside of the transmission column, the transmission magnetic roller, the multiple sets of magnetic rollers, and the driven wheel sharing a track, and a storage box slidably mounted inside the housing, the storage box being coaxially arranged with the driven wheel.

[0006] Preferably, the bottom of the housing is equipped with casters.

[0007] Preferably, a bearing is fixedly mounted on the top of the housing, and a first bracket is movably mounted on the top of the bearing.

[0008] Preferably, a second bracket is slidably disposed inside the first bracket, and a buckling mechanism for adjusting the telescopic length of the second bracket is disposed inside the second bracket.

[0009] Preferably, the buckling mechanism includes a box body, with the bottom of the second bracket fixedly installed to the box body. A sliding block is slidably arranged inside the box body, and straight grooves are opened on both sides of the sliding block. A support column is fixedly installed on one side of the sliding block, and the support column passes through holes opened in the box body, the second bracket, and the first bracket. A return spring is fixedly installed on one side of the sliding block, and one end of the return spring is fixedly installed to the box body. Two sets of driven rods are slidably arranged on the outside of the box body, and a sliding column is fixedly installed at one end of each of the two sets of driven rods. The two sets of sliding columns match the two sets of straight grooves. A transmission rod is fixedly installed at one end of the driven rod through a connecting plate, and the transmission rod passes through the top of the second bracket.

[0010] Preferably, the first bracket has multiple sets of holes.

[0011] The beneficial effects of the needle retrieval device proposed in this utility model are as follows: The device uses magnetic rollers and transmission magnetic rollers to generate magnetic force to attract fallen needles, while simultaneously driving the conveyor belt to rotate. The attracted needles are intercepted by the conveyor belt, which moves them until the magnetic force disappears, at which point the needle falls into the second support. This eliminates the need for medical staff to manually retrieve the needle, avoiding inconvenience during protective measures. A sensor is installed inside the second support; when a needle falls in, an external light illuminates, alerting medical staff that the needle has been found and further searching is unnecessary, reducing search time and improving needle retrieval efficiency. Furthermore, through the rotation of the bearings, the cooperation of the casters, and the movement of the first support on the bearings, the housing can change different angles to search various corners, increasing the needle retrieval area and improving the device's practicality. Subsequently, the second support can be retracted into the first support by pressing the transmission rod, and the first support can be folded on top of the housing for easy storage, saving space and thus increasing the operating space in the operating room.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1

[0022] Reference Figure 1-5 A needle-finding device for operating rooms includes a housing 1 with a needle-finding port 13 at the bottom. A servo motor 6 is fixedly mounted on the top of the housing 1, with the servo motor 6 placed on the outside to prevent magnetic forces from affecting its normal operation. A transmission gear set 7 is fixedly mounted on the end of the transmission shaft of the servo motor 6. Multiple sets of magnetic rollers 10 are rotatably mounted inside the housing 1. The magnetic rollers 10 generate magnetic force to attract needles while reducing the friction of the track 8 during rotation, thus reducing the energy consumption of the servo motor 6. A driven wheel 11 and a transmission column 1 are rotatably mounted inside the housing 1. 2. One end of the transmission column 12 passes through the housing 1 and is fixedly connected to the transmission gear set 7. A transmission magnetic roller 14 is fixedly installed on the outside of the transmission column 12. The transmission magnetic roller 14, multiple sets of magnetic rollers 10 and the driven wheel 11 are together fitted with a track 8. The housing 1, the second bracket 4, the transmission gear set 7 and various connecting structures are all made of aluminum. Aluminum is lightweight but has high strength, good corrosion resistance and plasticity. Moreover, aluminum has very weak magnetism and cannot generate strong magnetic interaction with magnets. A storage box 5 is slidably installed inside the housing 1. The storage box 5 is coaxially arranged with the driven wheel 11.

[0023] The bottom of the housing 1 is equipped with casters 9.

[0024] A bearing 2 is fixedly installed on the top of the housing 1, and a first bracket 3 is movably installed on the top of the bearing 2.

[0025] The caster wheel 9 and the bearing 2 complement each other. When it is necessary to change the angle, the bearing 2 can change the direction better by rotating. At the same time, because the caster wheel 9 is a ball, it can react to the turning of the bearing 2 more quickly.

[0026] A first bracket 3 is movably mounted on the top of the bearing 2. A second bracket 4 is slidably disposed inside the first bracket 3. A latching mechanism for adjusting the telescopic length of the second bracket 4 is disposed inside the second bracket 4.

[0027] In practical use, the servo motor 6 is first started, driving the transmission gear set 7 to rotate. After the transmission gear set 7 rotates, it continues to drive the transmission column 12 to rotate. The transmission column 12 then drives the transmission magnetic roller 14, which is fixedly installed thereto, to rotate. When the transmission magnetic roller 14 rotates, it drives the externally mounted track 8 to run under the support of the transmission magnetic roller 14 and the driven wheel 11. Then, medical staff can push the second support 4. The second support 4 generates a thrust on the first support 3, and the first support 3 generates a thrust on the bearing 2. The bearing 2 then pushes the housing 1 to move. During the movement, the magnetic force of the magnetic roller 10 is used to find the needle. After finding the needle in an open area, when it is necessary to find the needle in a corner, the medical staff only needs to rotate the second support 4. The second support 4 drives the first support 3 to rotate, and the first support 3 drives the bearing 2 to rotate. Then, the thrust is continued to be applied. When the universal wheel 9 senses the change in direction, due to the characteristics of its spherical shape, it will move according to the direction of the subsequent applied force. By varying the housing 1 at multiple angles, needle searching can be performed in more corners, increasing the needle-searching area and improving the practicality of the needle-searching device. During the search process, the magnetic roller 10 and the transmission magnetic roller 14 emit magnetic force outward through the needle-searching port 13 at the bottom of the housing 1, attracting fallen needles. When a needle is attracted, it is intercepted by the track 8 mounted on the outside. After being intercepted by the track 8, the needle moves with the track 8. When the track 8 moves to the driven wheel 11, the distance between the track 8 and the drive wheel 11 is... As the needle moves further away from the magnetic roller 10, the magnetic force weakens and can no longer attract the needle. The needle will then fall into the storage box 5 below the driven wheel 11. Once the needle is in the storage box 5, medical staff do not need to manually remove it, avoiding inconvenience for them while in full protective gear. After the needle falls into the storage box 5, the sensor inside the storage box 5 will be triggered, and the warning light on the outside of the storage box 5 will immediately light up, reminding medical staff that the needle has been found and there is no need to continue searching, thus reducing search time and improving needle retrieval efficiency.

[0028] Example 2

[0029] Currently, most needle-finding devices do not have a folding structure, which means they require a large amount of space to be placed, thus reducing the operating space in the operating room. (Refer to...) Figure 1-7As another preferred embodiment of this utility model, based on embodiment 1, it further includes a buckling mechanism comprising a box body 18, with the bottom of the second bracket 4 fixedly installed to the box body 18, a sliding block 20 slidably disposed inside the box body 18, and straight grooves 21 opened on both sides of the sliding block 20, the straight grooves 21 having a straight opening of 45 degrees and being obliquely chiseled, a support column 19 fixedly installed on one side of the sliding block 20, the support column 19 penetrating through the holes opened in the box body 18, the second bracket 4 and the first bracket 3, and a return spring 22 fixedly installed on one side of the sliding block 20, one end of the return spring 22 being connected to the box body 18. 8. Fixed installation: Two sets of driven rods 23 are slidably arranged on the outside of the box body 18. A sliding column 24 is fixedly installed at one end of each set of driven rods 23. The two sets of sliding columns 24 are matched with two sets of straight grooves 21. A transmission rod 17 is fixedly installed at one end of the driven rod 23 through a connecting plate. The transmission rod 17 passes through the top of the second bracket 4. The transmission rod 17 is on the outside, which makes it easy for medical staff to directly exert force on the support column 19 without bending over or other methods. They only need to hold the handle on the second bracket 4 and press the transmission rod 17 that passes through. The operation is simple, convenient and quick.

[0030] The first bracket 3 has multiple sets of holes. After the support column 19 passes through the holes, it plays a fixing role on the second bracket 4. There are multiple sets of holes, which can also be used to adjust the height of the second bracket 4 so that the needle finding device can be more suitable for different users.

[0031] In actual use, after the needle is located, medical staff need to store the housing 1 aside. At this time, they only need to hold the handle on the second bracket 4 and press the transmission rod 17 to apply pressure. The transmission rod 17 then applies pressure to the driven rod 23 through the connecting plate. The driven rod 23 will slide downward in the housing 18, which in turn drives the sliding column 24 to move downward. When the sliding column 24 moves downward, it passes through the inclined straight groove 21. Due to its inclination, the straight groove 21 converts the downward force transmitted by the sliding column 24 into the force that moves the sliding block 20 backward. At this time, the return spring 2... 2. As the sliding block 20 moves backward, it retracts, causing the sliding block 20 to move the support column 19 backward. The support column 19 will no longer be stuck in the hole on the first bracket 3. Consequently, the second bracket 4, without support on the first bracket 3, will slide downward until it reaches the bottom. At this point, the transmission rod 17 can be released. Then, a rotational force is applied to the second bracket 4. The second bracket 4, through the first bracket 3, drives the bearing 2 to rotate. When it rotates to a certain angle, the second bracket 4 can be lowered. Because the first bracket 3 rotates on the bearing 2, the first bracket 3 will fold the second bracket 4 onto the housing 1. Figure 4 This reduces the space required for storage, making it easier to store and saving space, thereby increasing the operating space in the operating room.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
