Description

Technical Field

[0001] The utility model relates to a needle finder, in particular to a safe needle finder which is convenient to adjust. Background Art

[0002] In surgical operations, surgical needles of various specifications and models are often used. Since the suture needles are very small, they are easily mixed with other instruments or dropped during use. Currently, hospitals use needle finders to search for them.

[0003] Existing needle finders are generally fixed in place. Therefore, it is generally necessary to select a needle finder of appropriate specifications based on the area of ​​the operating room to avoid choosing a needle finder with too small specifications, which will lead to low efficiency in needle finding. If the specifications are too large, it will be easily entangled or blocked by various objects when used in a small area, resulting in poor needle finding effect. At the same time, a large-sized needle finder is also likely to take up more space resources when placed.

[0004] Based on this, it is necessary to design a safe needle finder that is easy to adjust, so as to meet the needs of safe needle finding in operating rooms of different areas, while saving space resources when placing it. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Embodiment: A convenient and adjustable safety needle finder, such as Figure 1 and Figure 2 As shown, it includes a first box body 1, a second box body 2, a first magnet 201, a second magnet 202 and a driving assembly. The first box body 1 is slidably connected to the inner side of the second box body 2. The length of the second box body 2 is twice the length of the first box body 1. A pulley 5 is provided at the bottom of the first box body 1. A slide groove 203 for horizontal sliding of the first box body 1 is provided on the symmetrical inner wall of the second box body 2. A notch is provided at the bottom of the first box body 1 and the second box body 2. The bottoms of the first box body 1 and the second box body 2 are inclined from their circumferential outer walls to the notch. This arrangement To facilitate the needle to enter the first box body 1 and the second box body 2 through the gap, an N-shaped first magnet 201 is provided in the first box body 1, and an N-shaped second magnet 202 is provided in the second box body 2. The second magnet 202 slides with the first magnet 201. The first magnet 201 and the second magnet 202 are used to absorb the needle into the first box body 1 and the second box body 2 when finding the needle, thereby realizing the needle finding function. The first box body 1 and the second box body 2 are jointly provided with a driving component for driving the first box body 1 to slide horizontally along the slide groove 203 of the second box body 2.

[0023] like Figure 5As shown, the driving assembly includes a first protrusion 11, a second protrusion 21, a first threaded rod 6, a knob 601 and a connecting rod 602. A symmetrical second protrusion 21 is provided on the right outer wall of the second box body 2, and a connecting rod 602 is rotatably provided between the two second protrusions 21. The longitudinal section of the connecting rod 602 is a polygonal setting, preferably a hexagonal setting. A first protrusion 11 is provided on the outer wall of the first box body 1 away from the second box body 2 on the right side, and a first threaded rod 6 is movably provided between the first protrusion 11 and the second protrusion 21, wherein the first threaded rod 6 is rotatably connected to the first protrusion 11, and the first threaded rod 6 is threadedly connected to the second protrusion 21. The interior of the threaded rod 6 is hollow and slides with the connecting rod 602. The end of the first threaded rod 6 away from the two sides is connected to a knob 601. The thread grooves of the two first threaded rods 6 on the front and rear first boxes 1 are in opposite directions. The length of the connecting rod 602 is twice the length of the first threaded rod 6. Therefore, by turning any knob 601, the knob 601 drives the first threaded rod 6 connected to it to rotate, and the first threaded rod 6 drives the connecting rod 602 to rotate, and the other first threaded rod 6 is driven to rotate through the connecting rod 602. Through the rotation of the two first threaded rods 6, the first boxes 1 on the front and rear sides of the second box 2 are driven to move closer to or away from each other.

[0024] When in use, by turning the knob 601, the knob 601 drives the first threaded rod 6 connected thereto to rotate, and the rotation of the first threaded rod 6 drives the connecting rod 602 to rotate. Since the first threaded rod 6 is threadedly connected to the second protrusion 21, the inner cavity of the first threaded rod 6 slides horizontally along the connecting rod 602 when the first threaded rod 6 rotates, so that the first box body 1 slides into the inner side of the second box body 2 along the sliding groove 203, and the first magnet 201 slides into the lower inner side of the second magnet 202; at the same time, when the knob 601 drives the first threaded rod 6 connected thereto to rotate, the first threaded rod 6 drives the connecting rod 602 to rotate, and through the connecting rod 6 The rotation of 02 drives the other first threaded rod 6 to rotate. Since the thread grooves of the two first threaded rods 6 are in opposite directions, by turning any knob 601, the first boxes 1 on both sides of the second box 2 can be moved closer to or away from each other, so that according to the needs of needle finding, the first box 1 and the second box 2 can be unfolded to adapt to a large area of ​​needle finding scenes and improve the needle finding efficiency, or the first box 1 can be folded in the second box 2 to adapt to more crowded and small area of ​​needle finding scenes. When not in use, the first box 1 can be folded in the second box 2 to reduce the footprint of the needle finder.

[0025] like Figure 1-5As shown, it also includes a telescopic rod 4, a rotating shaft 401, a ring 7, a spring 701, a fixed plate 702, a clamping rod 703, an arc-shaped limit plate 71, a 7-shaped block 72 and a second threaded rod 8. The top of the second box body 2 is rotatably connected to the fixed plate 702, and the top of the fixed plate 702 is symmetrically provided with a 7-shaped block 72. The 7-shaped blocks 72 are rotatably connected with the rotating shaft 401. The rotating shaft 401 is connected to the telescopic rod 4. The top of the telescopic rod 4 is connected with a handle 3. The arc-shaped limit plate 71 is symmetrical. The ground is arranged on both sides of the rotating shaft 401, and the bottom of the arc-shaped limit plate 71 is connected to a clamping rod 703, and the clamping rod 703 is plugged into the through hole and the circular hole opened on the fixed plate 702. The two arc-shaped limit plates 71 are commonly connected to the circular ring 7, and a spring 701 is arranged between the circular ring 7 and the fixed plate 702. The two ends of the spring 701 are respectively connected to the circular ring 7 and the fixed plate 702. A second threaded rod 8 is threadedly connected to the 7-shaped block 72, and the lower end of the second threaded rod 8 is rotatably connected to the circular ring 7.

[0026] When the second threaded rod 8 is rotated forward, the second threaded rod 8 drives the ring 7 to move upward, and the ring 7 moves upward to drive the arc limiting plate 71 and the clamping rod 703 to move upward. After the clamping rod 703 is away from the circular hole opened in the top of the second box body 2, the fixing plate 702 can rotate freely. By rotating the fixing plate 702 90 degrees, the 7-shaped block 72, the rotating shaft 401 and the telescopic rod 4 on the fixing plate 702 are rotated 90 degrees. The second threaded rod 8 is rotated in the opposite direction, and the second threaded rod 8 drives the ring 7 downward. The ring 7 moves upward to drive the arc limiting plate 71 and the clamping rod 703 to move downward. The clamping rod 703 passes through the through hole on the fixing plate 702 from top to bottom and is inserted into the circular hole on the top of the second box body 2, thereby limiting the fixing plate 702. Through the above operation, the handle 3 and the telescopic rod 4 can be flexibly rotated to meet the user's needs.

[0027] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
