Description

Technical Field

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

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items that are used directly or indirectly on the human body. With the rapid development of medical technology, suture needles are used to suture surgical wounds during the operation of medical staff to ensure the patient's postoperative recovery. However, during the use and transfer of suture needles, they often fall to the ground.

[0003] Currently, in the operating room, after surgery, medical staff need to check the sutures. If the number of sutures is incorrect, repeated checks and searches are required. However, it's easy for sutures to fall to the ground. To ensure they aren't left inside the patient, they need to be found, but due to their small size, they are difficult to locate. When a suture falls to the ground, visual inspection alone is time-consuming and laborious. Furthermore, when the suture isn't visible on the ground, medical staff often kneel on one knee and use a magnet to examine the gaps under the operating table. Because the area under the table is dark, this affects the efficiency of finding the suture, and the increased size of the operating room makes the entire search extremely time-consuming. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a needle finder for operating room care, solving the problem that suture needles are difficult to locate due to their small size. When a suture needle falls to the ground, visual inspection alone is time-consuming and laborious. Furthermore, when the needle is not visible on the ground, medical staff often kneel on one knee and use a magnet to search the gaps under the table or cabinet. Since the area under the table or cabinet is dark, this affects the efficiency of needle finding. Moreover, with the increased size of the operating room, the entire search becomes extremely time-consuming.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] An operating room needle finder, comprising:

[0007] The base plate has a fixed magnetic plate at its bottom and rollers at the four corners of its bottom wall.

[0008] The operating frame includes a crossbar and two connecting rods. One end of the two connecting rods is fixedly connected to both sides of the base plate, and the crossbar is fixedly connected between the other ends of the two connecting rods. The two connecting rods are set at an angle.

[0009] The first magnetic attraction mechanism is set on the base plate and includes two movable magnetic plates. The two movable magnetic plates are symmetrically arranged on the top of the base plate, and the opposite sides of the two movable magnetic plates are hinged to the top two sides of the base plate through hinges.

[0010] A second magnetic attraction mechanism is slidably disposed at the bottom of the base plate; and

[0011] A drive structure is mounted on the operating frame and is used to drive the rotation and unfolding of the first magnetic attraction mechanism.

[0012] The aforementioned operating room needle finder, driven by a drive structure, causes two movable magnetic plates to flip to the sides of the bottom, allowing the fixed and movable magnetic plates to attract the suture needles together, thus enabling a faster search of the entire operating room. The second magnetic attraction mechanism allows it to slide under the operating table or into narrow areas to attract and search, avoiding the need for medical staff to lie down to search.

[0013] Furthermore, the hinge includes two hinge plates and a hinge shaft. Two symmetrically arranged hinge plates are provided on the top two sides of the base plate. The two ends of the hinge shaft are rotatably connected between the two hinge plates, and one end of the hinge shaft rotatably extends through one of the hinge plates to the outside. The two movable magnetic plates are driven by the drive structure to rotate around the hinge shaft, so that the two movable magnetic plates rotate to the two sides of the base plate.

[0014] Furthermore, the drive structure includes a drive rod, a gear set, and a check valve. The crossbar has a hollow interior, and the drive rod is rotatably fitted inside the crossbar. Both connecting rods have first receiving grooves along their axial direction, and the bottom plate has a second receiving groove that communicates with the first receiving groove. The gear set is located inside the first and second receiving grooves. Both ends of the drive rod rotate through the side walls of the two connecting rods and extend into the first receiving groove. By rotating the drive rod and transmitting the transmission through the gear set, the hinge shaft can be rotated. One end of the drive rod rotates through a connecting rod and extends to the outside. The check valve is located on the connecting rod to limit the rotation direction of the drive rod.

[0015] Furthermore, the gear set includes a first gear, a second gear, a third gear, a fourth gear, a first bevel gear, a second bevel gear, a first toothed belt, and a second toothed belt. The first gear is fixedly connected to both ends of the crossbar inside the first receiving groove. The second gear and the first bevel gear are rotatably arranged in parallel in the second receiving groove via a first support rod. The third gear and the second bevel gear are rotatably arranged in parallel in the second receiving groove via a second support rod. The second support rod is located above the first support rod, and the first bevel gear and the second bevel gear are meshed together. The first gear and the second gear are rotatably connected via a first toothed belt. The fourth gear is fixedly sleeved on the outer side of the end of the hinge shaft. The third gear and the fourth gear are rotatably connected via a second toothed belt.

[0016] Furthermore, the anti-reverse component includes an anti-reverse box, which is fixedly mounted on the connecting rod. The bottom of the anti-reverse box is open, and an anti-reverse shaft is rotatably mounted inside the anti-reverse box. One end of the anti-reverse shaft rotatably extends through the side wall of the anti-reverse box to the outside. An anti-reverse wheel is fixedly mounted on the outside of the drive rod and inside the anti-reverse box. Two symmetrically arranged first anti-reverse teeth and second anti-reverse teeth are fixedly mounted on the outside of the anti-reverse shaft and inside the anti-reverse box. The first anti-reverse teeth and second anti-reverse teeth can interlock with the anti-reverse wheel.

[0017] Furthermore, the anti-reverse component includes a limiting piece. The side of the anti-reverse box away from the connecting rod has a first limiting groove and a second limiting groove that are spaced apart. One end of the limiting piece is hinged to the end of the anti-reverse shaft located outside the anti-reverse box, and the other end is used to engage in the first limiting groove or the second limiting groove.

[0018] Furthermore, the second magnetic attraction mechanism includes two sliding plates. Slide grooves are provided on both sides of the base plate away from the operating frame. The two sliding plates are respectively inserted into the two slide grooves and slidably connected. The bottom of the two sliding plates is connected to a sliding magnetic plate by a spring.

[0019] Furthermore, a third receiving groove is provided at the bottom of the two sliding plates, the top of the sliding magnetic plate is inserted into the third receiving groove and slidably connected, and one end of the sliding magnetic plate is hinged to the top wall of the third receiving groove. Multiple springs are provided between the top of the sliding magnetic plate and the top wall of the third receiving groove.

[0020] Furthermore, a fourth receiving groove is provided on both sides of the base plate. The fourth receiving groove is connected to the third receiving groove. A push block is slidably provided in the fourth receiving groove, and the end of the push block is fixedly connected to the sliding plate.

[0021] The beneficial effects of this invention are as follows: This operating room needle finder uses a rotating drive rod, which, through the transmission of a gear set, causes two movable magnetic plates to flip to the sides of the bottom, allowing the fixed and movable magnetic plates to attract the suture needles together, thus enabling a faster search of the entire operating room floor. Simultaneously, a backstop device restricts the rotation direction of the drive rod, preventing it from rotating backward. Furthermore, by moving the sliding magnetic plate to the front of the base plate, it can extend under the operating table or into narrow areas to attract and search for the needle, avoiding the need for medical staff to lie down to search.

[0040] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0041] In the description of this invention, it should be understood that the terms "center", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation and positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific way. Therefore, they should not be construed as limitations on this invention.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0043] Please see Figures 1 to 3 The present invention provides an operating room nursing needle finder, comprising a base plate 10, an operating frame 20, a first magnetic attraction mechanism 30, a second magnetic attraction mechanism 40, and a driving structure 50. The bottom of the base plate 10 is provided with a fixed magnetic plate 11, and each of the four corners of the bottom wall of the base plate 10 is provided with a roller 60 with a self-locking function. The operating frame 20 includes a crossbar 21 and two connecting rods 22. One end of the two connecting rods 22 is fixedly connected to both sides of the base plate 10, and the crossbar 21 is fixedly connected between the other ends of the two connecting rods 22, and the two connecting rods 22 are inclined. The first magnetic attraction mechanism 30 is disposed on the base plate 10, and the second magnetic attraction mechanism 40 is slidably disposed on the bottom of the base plate 10. The driving structure 50 is disposed on the operating frame 20 and is used to drive the rotation and unfolding of the first magnetic attraction mechanism 30.

[0044] In use, when searching the bottom of the operating room, the first magnetic attraction mechanism 30 is flipped by the drive structure 50, so that the first magnetic attraction mechanism 30 is flipped to the side of the bottom plate 10, thereby increasing the searching area of ​​the needle finder, saving time, and thus enabling a faster search of the entire operating room, so as to attract the suture needle to the fixed magnetic plate 11 and the first magnetic attraction mechanism 30; when searching under the operating table or in narrow areas, the second magnetic attraction mechanism 40 is slid out. Because the second magnetic attraction mechanism 40 is long and narrow, it can go deep under the operating table or in narrow areas to attract and search, avoiding the need for medical staff to lie down to search.

[0045] Please refer to the following: Figure 5 Specifically, the first magnetic attraction mechanism 30 includes two movable magnetic plates 31, which are symmetrically arranged on the top of the base plate 10. The opposite sides of the two movable magnetic plates 31 are hinged to the top sides of the base plate 10 via hinge members. Each hinge member includes two hinge plates 32 and a hinge shaft 33. Two symmetrically arranged hinge plates 32 are respectively provided on the top sides of the base plate 10. The two ends of the hinge shaft 33 are rotatably connected between the two hinge plates 32, and one end of the hinge shaft 33 rotatably extends outward through one of the hinge plates 32. Driven by the drive structure 50, the two movable magnetic plates 31 rotate around the hinge shaft 33, causing them to rotate to the sides of the base plate 10. The movable magnetic plates 31 and the fixed magnetic plate 11 are magnetic and can attract suture needles.

[0046] Initially, the two movable magnetic plates 31 are stored on top of the base plate 10. When it is necessary to unfold the two movable magnetic plates 31, the hinge shaft 33 is driven to rotate by the drive structure 50. The hinge shaft 33 drives the movable magnetic plates 31 to rotate, causing the movable magnetic plates 31 to start to flip until they flip 180 degrees. At this time, the movable magnetic plates 31 are flipped to the side of the base plate 10, and the bottom surface of the movable magnetic plates 31 is flush with the fixed magnetic plate 11. By pushing the base plate 10 to move, the suture needles on the bottom surface can be attracted to the movable magnetic plates 31 and the fixed magnetic plate 11. The unfolding of the two movable magnetic plates 31 increases the search area on the ground, and the operating room can be searched more quickly.

[0047] Please refer to the following: Figure 6 , Figures 7 to 8In this embodiment, the drive structure 50 includes a drive rod 51, a gear set 52, and a backstop 53. The crossbar 21 has a hollow interior. The drive rod 51 is rotatably sleeved inside the crossbar 21. The two connecting rods 22 are provided with first receiving grooves 23 along the axial direction. The bottom plate 10 is provided with a second receiving groove 12, which communicates with the first receiving groove 23. The gear set 52 is disposed inside the first receiving groove 23 and the second receiving groove 12. The two ends of the drive rod 51 rotate through the side walls of the two connecting rods 22 and extend into the first receiving groove 23. By rotating the drive rod 51, the transmission of the gear set 52 can drive the rotation of the hinge shaft 33. One end of the drive rod 51 rotates through a connecting rod 22 and extends to the outside. The backstop 53 is disposed on the connecting rod 22 to limit the rotation of the drive rod 51.

[0048] When it is necessary to drive the movable magnetic plate 31 to rotate, the drive rod 51 rotates, and through the transmission of the gear set 52, the hinge shaft 33 rotates, thereby driving the movable magnetic plate 31 to rotate. Moreover, due to the restriction of the anti-reverse component 53, the drive rod 51 will not be driven to rotate by the movable magnetic plate 31, thus preventing the movable magnetic plate 31 from losing control after the medical staff stops rotating the drive rod 51 during operation. At the same time, by adjusting the anti-reverse component 53, the drive rod 51 can be rotated in the reverse direction.

[0049] The gear set 52 includes a first gear 521, a second gear 522, a third gear 523, a fourth gear 524, a first bevel gear 525, a second bevel gear 526, a first toothed belt 527, and a second toothed belt 528. The first gear 521 is fixedly connected to both ends of the crossbar 21 inside the first receiving groove 23. The second gear 522 and the first bevel gear 525 are rotatably arranged in parallel in the second receiving groove 12 through the first support rod 54. The third gear 523 and the second bevel gear 526 are rotatably arranged in parallel in the second receiving groove 12 through the second support rod 55. The second support rod 55 is located above the first support rod 54, and the first bevel gear 525 and the second bevel gear 526 are meshed together. The first gear 521 and the second gear 522 are rotatably connected through the first toothed belt 527. The fourth gear 524 is fixedly sleeved on the outer side of the end of the hinge shaft 33. The third gear 523 and the fourth gear 524 are rotatably connected through the second toothed belt 528. After the drive rod 51 is rotated, the first bevel gear 525 is driven to rotate through the transmission of the first gear 521 and the second gear 522. The first bevel gear 525 drives the second bevel gear 526 to rotate. Then, the hinge shaft 33 is driven to rotate through the transmission of the third gear 523 and the fourth gear 524, thereby causing the corresponding movable magnetic plate 31 to flip and unfold the two movable magnetic plates 31.

[0050] Please refer to the following: Figure 9The anti-reverse component 53 includes an anti-reverse box 531, which is fixedly mounted on the connecting rod 22. The bottom of the anti-reverse box 531 is open. An anti-reverse shaft 532 is rotatably mounted inside the anti-reverse box 531. One end of the anti-reverse shaft 532 rotatably extends through the side wall of the anti-reverse box 531 to the outside. An anti-reverse wheel 533 is fixedly mounted on the outside of the drive rod 51 and inside the anti-reverse box 531. Two symmetrically arranged first anti-reverse teeth 534 and second anti-reverse teeth 535 are fixedly mounted on the outside of the anti-reverse shaft 532 and inside the anti-reverse box 531. The first anti-reverse teeth 534 and the second anti-reverse teeth 535 can interlock with the anti-reverse wheel 533. Before the drive rod 51 is rotated in the forward direction, the anti-reverse shaft 532 is rotated so that the end of the first anti-reverse tooth 534 is engaged with the anti-reverse wheel 533, so that the drive rod 51 can only rotate in the forward direction and cannot rotate in the reverse direction. This prevents the drive rod 51 from rotating due to the driving of the movable magnetic plate 31 after the medical staff stops rotating the drive rod 51. Similarly, when the end of the second anti-reverse tooth 535 is engaged with the anti-reverse wheel 533, the drive rod 51 can only rotate in the reverse direction and cannot rotate in the forward direction.

[0051] Preferably, the anti-reverse component 53 includes a limiting piece 536. The anti-reverse box 531 has a first limiting groove 537 and a second limiting groove 538 spaced apart on its side away from the connecting rod 12. One end of the limiting piece 536 is hinged to the end of the anti-reverse shaft 532 located outside the anti-reverse box 531, and the other end is used to engage in the first limiting groove 537 or the second limiting groove 538. When the end of the first anti-reverse tooth 534 engages against the anti-reverse wheel 533, and the medical staff needs to change the anti-reverse direction of the drive rod 31, the end of the limiting piece 536 is pulled out from the first limiting groove 537. By rotating the anti-reverse shaft 532, the end of the second anti-reverse tooth 535 engages against the anti-reverse wheel 533, so that the end of the limiting piece 536 can engage in the second limiting groove 538.

[0052] like Figure 1 , Figure 2 and Figure 10 As shown, in this embodiment, the second magnetic attraction mechanism 40 includes two sliding plates 41. Slide grooves 45 are provided on both sides of the base plate 10 away from the operating frame 20. The two sliding plates 41 are respectively inserted into the two slide grooves 45 and slidably connected. A sliding magnetic plate 42 is connected to the bottom of the two sliding plates 41 via a spring 43. By sliding the two sliding plates 41 out of their corresponding slide grooves 45, the two sliding plates 41 move to the front of the base plate 10. When encountering narrow areas that are difficult for medical staff to locate, the base plate 10 is pushed to move the sliding plates 41 to the narrow area for attraction and retrieval.

[0053] Preferably, the bottom of the two sliding plates 41 is provided with a third receiving groove 46, and the top of the sliding magnetic plate 42 is inserted into the third receiving groove 46 for sliding connection. One end of the sliding magnetic plate 42 is hinged to the inner top wall of the third receiving groove 46 by a connecting rope 48, so that the sliding magnetic plate 42 cannot be completely ejected outside the third receiving groove 46. Multiple springs 43 are provided between the top of the sliding magnetic plate 42 and the inner top wall of the third receiving groove 46. When the connecting rope 48 is fully extended, the end of the sliding magnetic plate 42 is still located in the third receiving groove 46. In the initial state, the springs 43 are in a compressed state. When the sliding plate 41 is completely slid out of the groove 45, the elastic force of the springs 43 ejects the sliding magnetic plate 42 from the third receiving groove 46. At this time, the sliding magnetic plate 42 is in an inclined state. When it is necessary to slide the sliding plate 41 into the groove 45, the inclination of the sliding magnetic plate 42 allows the sliding magnetic plate 42 to be smoothly stored in the third receiving groove 46.

[0054] Furthermore, a fourth receiving groove 47 is provided on both sides of the base plate 10. The fourth receiving groove 47 is connected to the third receiving groove 46. A push block 44 is slidably provided in the fourth receiving groove 47, and the end of the push block 44 is fixedly connected to the sliding plate 41. By pushing the push block 44, the sliding plate 41 can be driven to slide to the outside of the groove 45.

[0055] The working principle of this invention is as follows: When medical staff need to locate suture needles on the floor of the operating room, they rotate the anti-reverse shaft 532 in the forward direction, causing the end of the first anti-reverse tooth 534 to engage with the anti-reverse wheel 533. At this time, the end of the limiting piece 536 is inserted into the first limiting groove 537 and engaged. Then, the drive rod 51 is rotated, which drives the first bevel gear 525 to rotate through the transmission of the first gear 521 and the second gear 522. The first bevel gear 525 drives the second bevel gear 526 to rotate. Then, through the transmission of the third gear 523 and the fourth gear 524, the hinge shaft 33 is rotated, causing the two movable magnetic plates 31 to start to flip until the two movable magnetic plates 31 are flipped to both sides of the base plate 10. After that, the medical staff can push the operating frame 20 to move so that the suture needles on the floor can be attracted to the movable magnetic plates 31 and the fixed magnetic plates 11.

[0056] When it is necessary to store the two movable magnetic plates 31, the limiting piece 536 is pulled out from the first limiting groove 537 and the anti-reverse shaft 532 is rotated so that the end of the second anti-reverse tooth 535 is engaged against the anti-reverse wheel 533, while the end of the first anti-reverse tooth 534 is disengaged from the anti-reverse wheel 533; then the end of the limiting piece 536 is inserted into the second limiting groove 538 and engaged; then the drive rod 51 is rotated in the reverse direction and driven by the transmission of the gear set 52 to rotate the hinge shaft 33, so that the ends of the two movable magnetic plates 31 flip up and rise until the two movable magnetic plates 31 fall onto the top of the bottom plate 10.

[0057] When medical staff need to locate suture needles in the narrow area of ​​the operating room, pushing the push block 44 can cause the sliding plate 41 to slide to the outside of the slide groove 45. The elastic force of the spring 43 will pop the sliding magnetic plate 42 out of the third receiving groove 46. At this time, the sliding magnetic plate 42 is in an inclined state, so that the sliding magnetic plate 42 can be inserted into the narrow area to attract the suture needle. When the push block 44 is pushed back, the sliding magnetic plate 42 is in an inclined position, which will cause the sliding plate 41 to slide into the third receiving groove.

[0058] The beneficial effects of this invention are as follows: This operating room needle finder, through the transmission of the rotating drive rod 51 via the gear set 52, causes the two movable magnetic plates 31 to flip to both sides of the bottom, so that the fixed magnetic plate 11 and the movable magnetic plate 31 together attract the suture needle, thereby enabling a faster search of the entire bottom surface of the operating room; at the same time, the anti-reverse component 53 can limit the rotation direction of the drive rod 51, preventing the drive rod 51 from rotating back; and by moving the sliding magnetic plate 42 to the front side of the bottom plate 10, the sliding magnetic plate 42 can extend under the operating table or move in narrow areas to attract and search, avoiding the need for medical staff to lie down to search.
