Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to a dual-scene operating room needle locator. Background Technology

[0002] With the continuous development of surgical procedures in terms of type, complexity, and precision, the types and models of sutures required during surgery are constantly changing. The "Operating Room Nursing Practice Guidelines" places great emphasis on suture verification. However, surgical sutures, as foreign objects, are still frequently left inside patients. Surgical sutures are crucial items to count during surgery. Due to their tiny size, lost sutures are difficult to find, often delaying surgery and increasing surgical risks, causing greater suffering and financial loss to patients. Therefore, specialized suture-finding devices are necessary.

[0003] Currently used needle-finding devices can only locate needles on the ground. When a needle falls onto the operating table, it cannot be located by the device, which limits the device's functionality. To address this issue, we provide a dual-scenario operating room needle-finding device. Summary of the Invention

[0004] In view of the problem that existing technologies cannot locate needles when they fall on the operating table, thus limiting the implementation of the device, the purpose of this invention is to provide a dual-scene operating room needle locator.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A dual-scene operating room needle-finding device includes:

[0007] A mobile trolley and two rotating push rods rotatably connected to the top of the mobile trolley;

[0008] The metal detector is provided in multiple groups, with each group having multiple metal detectors, and the multiple metal detectors are distributed at equal distances at the bottom of the mobile vehicle.

[0009] A mode switching aid is located on both sides of the mobile cart and is used to switch the needle finding mode of the mobile cart. The mode switching aid is used to switch the mobile cart between the ground moving needle finding mode and the operating table fixed needle finding mode.

[0010] The mode switching assistant includes:

[0011] The sliding frames are slidably connected to both sides of the rotating push rod. Each sliding frame has two clamping components rotatably connected to its inner side. In the fixed needle-finding mode of the operating table, the clamping components are clamped to the edge of the operating table, so that the moving trolley is suspended above the operating table.

[0012] An adjustment component, located inside the mobile trolley, is used to adjust the position of each group of metal detectors installed at the bottom of the mobile trolley.

[0013] Optionally, the clamping assembly includes a swing rod rotatably connected to the inner side of the sliding frame, an auxiliary rod is provided at the front end of the swing rod, a second rotating block is rotatably connected at the front end of the auxiliary rod, a first clamping block is fixedly connected to one side of the second rotating block, and a second clamping block is provided on the inner side of the first clamping block.

[0014] Optionally, a one-way threaded screw is rotatably connected to the inner side of the first clamping block, and one end of the one-way threaded screw extends through to the top of the first clamping block. A limiting block is fixedly connected to one side of the second clamping block. The limiting block is threadedly connected to the outer wall of the one-way threaded screw. A limiting groove matching the limiting block is opened on the inner side of the first clamping block. The second clamping block is slidably connected to the first clamping block through the limiting block fixedly connected to one side.

[0015] Optionally, the clamping assembly further includes a guide groove formed inside the swing rod, and an extension rod is slidably connected inside the guide groove. The auxiliary rod is rotatably connected to the extension rod through a third rotating block.

[0016] Optionally, the adjustment assembly includes a slot formed inside the moving trolley, with two transmission rods rotatably connected to the inside of the slot. Each transmission rod consists of two reciprocating lead screws, and a moving block is installed on the outer wall of each reciprocating lead screw. A set of swing blocks is provided at the bottom of each moving block, and multiple swing blocks are provided in each set. Each swing block is fixedly connected to a metal detector, and an automatic bending auxiliary assembly is provided inside each set of swing blocks.

[0017] Optionally, a limiting rod is fixedly connected to the inner side of the slot, and an auxiliary groove matching the limiting rod is opened on the inner side of the moving block. The moving block is slidably connected to the limiting rod through the auxiliary groove opened on the inner side.

[0018] Optionally, the adjustment assembly further includes a spur gear fixedly connected to the outer wall of the transmission rod, a rack fixedly connected to the bottom of the sliding frame via a connecting block, and the rack meshing with the spur gear. The inner side of the moving trolley is provided with a rectangular groove communicating with the empty slot, and the rectangular groove matches the connecting block.

[0019] Optionally, the automatic bending assist component includes a first rotating block disposed between every two of the swing blocks;

[0020] The swing block on the side closer to the moving block is fixedly connected to the first rotating block, and the swing block on the side farther from the moving block is rotatably connected to the first rotating block.

[0021] Optionally, the automatic bending auxiliary component further includes a rotating shaft fixedly connected to both ends of the first rotating block, a groove is provided on the inner side of the swing block, one end of the rotating shaft passes through the inner side of the groove and is fixedly connected to a ring, and a torsion spring is installed between the ring and the groove.

[0022] Optionally, the bottom of the mobile trolley is fixedly connected to two support plates, and each set of swing blocks is attached to the top of the support plates.

[0023] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0024] In the above scheme, by setting a mode switching assistant, the device can perform needle retrieval operations both on the ground and on the operating table, thereby improving the efficiency of needle retrieval for medical staff and enhancing the overall practicality of the device.

[0025] By setting up an adjustment component, when the moving trolley moves longitudinally, the sliding frame is limited, which causes the spur gear and rack to mesh during the lateral movement of the moving trolley, driving the transmission rod to rotate. This allows the two sets of metal detectors at the bottom of the moving trolley to move away from the moving trolley, thus realizing lateral detection. This expands the detection range of the metal detectors from "only covering the area directly below the moving trolley" to "the lateral areas on both sides of the moving trolley", such as the outer edge of the operating table frame and the edge of the surgical drape, areas that were originally not covered due to the limited width of the moving trolley. This effectively eliminates lateral detection blind spots, prevents needles from being missed in the gaps or edges not covered on both sides of the moving trolley, and reduces the needle finding blind spots, thereby further improving the convenience of needle finding.

[0026] By setting up an automatic bending auxiliary component, the torsion springs between each pair of swing blocks, from the center to the tail, are initially in a compressed state. When the compressed torsion springs move away from the support plate through the swing blocks, the swing blocks can rotate slightly at a certain angle under the action of the torsion springs. Through multiple compressed torsion springs, the metal detector can tilt at a certain angle during lateral movement to cover and approach the patient for close detection. The near-surface area of ​​the operating table is not a flat plane (such as the patient's body contour protrusion, surgical drape folds, and local undulations caused by instrument placement). Traditional fixed-angle metal detectors are prone to forming "gaps" with the surface, causing needles to be missed in the gaps. The core advantage of the automatic bending auxiliary component is "adaptive tilting". Since the detection sensitivity of the metal detector is directly related to the "detection distance": the closer to the metal needle, the stronger the sensing signal and the less likely it is to be missed, especially for small diameter suture needles. Therefore, the accuracy of detection can be improved by using an adaptive tilting metal detector. Attached Figure Description

[0044] like Figures 1 to 8 As shown, this embodiment of the invention provides a dual-scene operating room needle retrieval device, including: a mobile cart 1 and two rotating push rods 2 rotatably connected to the top of the mobile cart 1; metal detectors 10, with multiple sets of metal detectors 10, each set containing multiple metal detectors 10, and the multiple metal detectors 10 being evenly distributed at the bottom of the mobile cart 1; a mode switching assistant, located on both sides of the mobile cart 1, used to switch the needle retrieval mode of the mobile cart 1, the mode switching assistant being used to switch the mobile cart 1 between a ground-moving needle retrieval mode and a fixed needle retrieval mode on the operating table; the mode switching assistant includes: sliding frames 3 slidably connected to both sides of the rotating push rods 2, each sliding frame 3 having two clamping components rotatably connected to its inner side, in the fixed needle retrieval mode on the operating table, the clamping components clamp to the edge of the operating table, so that the mobile cart is suspended above the operating table.

[0045] Specifically, the clamping assembly includes a swing rod 4 rotatably connected to the inner side of the sliding frame 3. An auxiliary rod 5 is provided at the front end of the swing rod 4. A second rotating block 17 is rotatably connected to the front end of the auxiliary rod 5. A first clamping block 19 is fixedly connected to one side of the second rotating block 17. A second clamping block 20 is provided inside the first clamping block 19. A one-way threaded screw 21 is rotatably connected to the inner side of the first clamping block 19, and one end of the one-way threaded screw 21 extends through to the top of the first clamping block 19. A limit block is fixedly connected to one side of the second clamping block 20. The limit block is threaded to the outer wall of the one-way threaded screw 21. A limit groove matching the limit block is provided on the inner side of the first clamping block 19. The second clamping block 20 is slidably connected to the first clamping block 19 through the limit block fixedly connected to one side. The clamping assembly also includes a guide groove provided inside the swing rod 4. An extension rod 18 is slidably connected inside the guide groove. The auxiliary rod 5 is rotatably connected to the extension rod 18 through a third rotating block 26.

[0046] The top of the mobile cart 1 can be equipped with an alarm light for detection. When the metal detector 10 senses a needle, it transmits a signal to the PLC controller, which then controls the alarm light to perform an alarm operation. How the metal detector 10 performs the detection operation is existing technology, so it is not described in detail in this solution. First, when the user needs to perform a needle-finding operation on the ground, the rotating push rod 2 can be rotated out to push the mobile cart 1 to move on the ground and pass through the metal detector 10 for detection, thereby performing the needle-finding operation.

[0047] When medical staff need to locate the needle on the operating table, the rotating push rod 2 can be retracted. Then, the swing rods 4 on both sides of the moving cart 1 can be rotated, and the auxiliary rod 5 can be pulled to adjust its length. At the same time, the auxiliary rod 5 can be rotated 90 degrees, and the angle of the second rotating block 17 can be adjusted as needed until the second clamping block 20 and the first clamping block 19 can be adjusted to be located on both sides of the operating table frame. Then, the one-way threaded screw 21 can be rotated until the second clamping block 20 and the first clamping block 19 form a clamp on the operating table frame. After the four second clamping blocks 20 and the first clamping blocks 19 are clamped on the operating table frame and support the moving cart 1, the staff can manually push the moving cart 1 to move longitudinally along the patient's surgical site for detection. This realizes needle locating in both ground and operating table scenarios, which greatly improves the efficiency of needle locating for medical staff and enhances the overall practicality of the device.

[0048] like Figures 2 to 4As shown, the adjustment assembly, located inside the mobile trolley 1, is used to adjust the position of each group of metal detectors 10 installed at the bottom of the mobile trolley 1. The adjustment assembly includes a slot 6 opened inside the mobile trolley 1. Two transmission rods 7 are rotatably connected to the inside of the slot 6. Each transmission rod 7 consists of two reciprocating lead screws. A moving block 13 is installed on the outer wall of each reciprocating lead screw. A set of swing blocks 12 is provided at the bottom of each moving block 13. Multiple swing blocks 12 are provided in each set, and each swing block 12 is connected to a metal detector 10. 0. Fixed connection, the inner side of the empty slot 6 is fixedly connected to the limit rod 14, the inner side of the moving block 13 is provided with an auxiliary slot that matches the limit rod 14, the moving block 13 is slidably connected to the limit rod 14 through the auxiliary slot on the inner side, the adjustment component also includes a spur gear 8 fixedly connected to the outer wall of the transmission rod 7, the bottom of the sliding frame 3 is fixedly connected to a rack 9 through a connecting block 16, and the rack 9 meshes with the spur gear 8, the inner side of the moving trolley 1 is provided with a rectangular slot that communicates with the empty slot 6, and the rectangular slot matches the connecting block 16.

[0049] When the moving carriage 1 moves longitudinally, the sliding frame 3 is limited, so when the moving carriage 1 moves laterally, the spur gear 8 and the spur rack 9 mesh, driving the transmission rod 7 to rotate. This allows the two sets of metal detectors 10 at the bottom of the moving carriage 1 to move away from the moving carriage 1, thus realizing the lateral detection operation. This expands the detection range of the metal detectors 10 from "only covering the area directly below the moving carriage 1" to "the lateral areas on both sides of the moving carriage 1", such as the outer edge of the operating table frame and the edge of the surgical drape, areas that were originally not covered due to the limited width of the moving carriage 1. This effectively eliminates the lateral detection blind spot, prevents needles from being missed in the gaps or edges not covered on both sides of the moving carriage 1, and reduces the needle finding blind spot, thereby further improving the convenience of needle finding.

[0050] like Figures 2 to 8 As shown, each set of swing blocks 12 is equipped with an automatic bending auxiliary component on its inner side. The automatic bending auxiliary component includes a first rotating block 15 disposed between every two swing blocks 12. The swing block 12 on the side closer to the moving block 13 is fixedly connected to the first rotating block 15, and the swing block 12 on the side farther from the moving block 13 is rotatably connected to the first rotating block 15. The automatic bending auxiliary component also includes a rotating shaft 23 fixedly connected to both ends of the first rotating block 15. A groove 22 is provided on the inner side of the swing block 12. One end of the rotating shaft 23 passes through the inner side of the groove 22 and is fixedly connected to a ring 24. A torsion spring 25 is installed between the ring 24 and the groove 22. Two support plates 11 are fixedly connected to the bottom of the moving trolley 1, and each set of swing blocks 12 is attached to the top of the support plate 11.

[0051] The torsion springs 25 between each pair of swing blocks 12, arranged from the center to the tail, are initially in a compressed state. When the compressed torsion springs 25 move away from the support plate 11 through the swing blocks 12, the swing blocks 12 can rotate slightly at a certain angle under the action of the torsion springs 25. Through multiple compressed torsion springs 25, the metal detector 10 can tilt at a certain angle during lateral movement to cover and approach the patient for detection. The near-surface area of ​​the operating table is not a flat plane (such as the patient's body contour protrusion, surgical drape folds, and local undulations formed by the placement of instruments). The traditional fixed-angle metal detector 10 is prone to forming "gaps" with the surface, causing needles to be missed in the gaps. The core advantage of the automatic bending auxiliary component is "adaptive tilt". Since the detection sensitivity of the metal detector 10 is directly related to the "detection distance": the closer to the metal needle, the stronger the sensing signal and the more difficult it is to miss (especially for small diameter suture needles), the accuracy of detection can be improved by using an adaptive tilt metal detector 10.

[0052] The working process provided by the technical solution of this invention is as follows:

[0053] The top of the mobile cart 1 can be equipped with an alarm light for detection. When the metal detector 10 senses a needle, it transmits a signal to the PLC controller, which then controls the alarm light to perform an alarm operation. How the metal detector 10 performs the detection operation is existing technology, so it is not described in detail in this solution. First, when the user needs to perform a needle-finding operation on the ground, the rotating push rod 2 can be rotated out to push the mobile cart 1 to move on the ground and pass through the metal detector 10 for detection, thereby performing the needle-finding operation.

[0054] When medical staff need to locate the needle on the operating table, the rotating push rod 2 can be retracted. Then, the swing rods 4 on both sides of the moving trolley 1 can be rotated, and the auxiliary rod 5 can be pulled to adjust its length. At the same time, the auxiliary rod 5 can be rotated 90 degrees, and the angle of the second rotating block 17 can be adjusted as needed until the second clamping block 20 and the first clamping block 19 can be adjusted to be located on both sides of the operating table frame. Then, the one-way threaded screw 21 can be rotated until the second clamping block 20 and the first clamping block 19 form a clamp on the operating table frame. After the four second clamping blocks 20 and the first clamping blocks 19 are clamped on the operating table frame to support the moving trolley 1, the staff can manually push the moving trolley 1 to move longitudinally along the patient's surgical site for detection.

[0055] When the mobile trolley 1 moves longitudinally, the sliding frame 3 is limited, so when the spur gear 8 and the spur rack 9 mesh during the lateral movement of the mobile trolley 1, the drive rod 7 rotates, so that the two sets of metal detectors 10 at the bottom of the mobile trolley 1 can move away from the mobile trolley 1, thereby realizing the lateral detection operation.

[0056] The torsion springs 25 between each pair of swing blocks 12, arranged from the center to the tail end, are initially in a compressed state. When the torsion springs 25 in the compressed state move away from the support plate 11 through the swing blocks 12, the swing blocks 12 can rotate slightly at a certain angle under the action of the torsion springs 25. Through multiple torsion springs 25 in a compressed state, the metal detector 10 can tilt at a certain angle during the lateral movement to cover and get close to the patient for detection.

[0057] This invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this invention. To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0058] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
