Technical Field

[0001] The invention relates to the field of medical auxiliary equipment, and in particular to a handheld push-type needle picking device. Background Art

[0002] Medical needles are a commonly used tool in medical procedures, mainly used for injecting drugs, extracting body fluids, infusions and other operations. They are usually made of stainless steel and have different lengths and diameters to suit different medical procedures. During the specific operation process, because the needle is very thin, medical staff generally wear gloves when working, so it is easy for the needle to fall accidentally. At this time, if the medical staff squats down to pick up the needle manually, the gloves will be contaminated, and may even cause the medical staff to be accidentally pricked by the needle.

[0003] Therefore, a hand-held push-type needle picking device is now developed to address the above problems. Summary of the invention

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] A handheld push-type needle picking device, such as Figure 1-Figure 9As shown, it includes a mounting rod 1, a mounting seat 2 is connected to the lower part of the mounting rod 1, and two rolling balls 3 are rotatably connected to the bottom of the mounting seat 2, and the rolling balls 3 are used to assist the mounting seat 2 to move quickly on the ground. A mounting cylinder 4 is installed on the right side of the mounting rod 1, and a rotating seat 5 is rotatably arranged on the rear side of the mounting cylinder 4. A magnetic suction frame 6 for adsorbing and picking up the needle is installed on the rotating seat 5, and a sliding ring 8 is slidably connected to the mounting cylinder 4. Two positioning frames 7 are installed at the lower part of the sliding ring 8. The bottom of the positioning frames 7 are all arc-shaped structures, and the positioning frames 7 are used to position and limit the needle drop area. A cam 9 is rotatably connected inside the mounting cylinder 4, and a first spring 10 is connected between the sliding ring 8 and the mounting cylinder 4. A missing gear 12 is arranged on the cam 9, and a volute spring 11 is connected between the missing gear 12 and the mounting cylinder 4. A plurality of fixed rods 15 are arranged inside the mounting rod 1, and a rotating wheel 16 is installed on the cam 9. A pulling handle 18 is rotatably arranged on the left part of the mounting rod 1. The movable handle 18 is an L-shaped structure. A pull rope 17 is connected between the pulling handle 18 and the rotating wheel 16. The pull rope 17 is wound between the fixed rods 15. A spur gear 13 is arranged on the inner side of the rotating seat 5. The spur gear 13 and the missing gear 12 are meshed with each other. A clamp 19 is arranged on the left part of the mounting rod 1. Two second springs 20 are arranged on the clamp 19. The clamp 19 is used to lock and fix the pulling handle 18. A toggle member 22 is installed on the cam 9. An elastic sheet 21 is arranged on the inner side of the mounting tube 4. A fixed ball for improving the locking stability is arranged on the elastic sheet 21. The elastic sheet 21 is used to lock and fix the sliding ring 8. A detection head 24 is arranged at the bottom of the mounting tube 4. The detection head 24 is used to assist the operator to view the ground situation. A viewing screen 14 is installed on the upper part of the mounting rod 1. The viewing screen 14 is used to intuitively display the shooting situation of the detection head 24. A hand-holding rubber member 23 is arranged on the top of the mounting rod 1. Anti-slip grooves are arranged on the hand-holding rubber member 23.

[0027] It should be noted that when the needle falls on the ground, in order to facilitate medical staff to quickly pick up the needle, the present device can be used for operation assistance. First, by holding the mounting rod 1, holding the hand-holding rubber member 23, and then driving the device to move as a whole, the bottom of the device is moved to the needle drop area, and after positioning is completed, the pull handle 18 is pressed inward for a distance, so that the clamp 19 locks and fixes the pull handle 18 for the first time under the action of the second spring 20. At this time, as the pull handle 18 moves, it will drive the pull rope 17 to move, and the pull rope 17 will be locked after the movement is completed. After the completion, it will drive the rotating wheel 16 to rotate, so that the cam 9 rotates 90 degrees. The cam 9 rotates 90 degrees to press the sliding ring 8 downward, so that the sliding ring 8 drives the positioning frame 7 to move downward, thereby completing the positioning of the needle drop area. At this time, the positioning frame 7 will move downward and contact the ground, locking the needle in the inner area of ​​the positioning frame 7. At the same time, the elastic sheet 21 will be deformed once due to the downward movement of the sliding ring 8, and will reset after the sliding ring 8 passes the position of the fixed ball, thereby relying on the fixed ball to fix the sliding ring 8. The first spring 10 remains in a compressed state. Observe the viewing screen 14 to determine the specific position of the needle, and then continue to press the pull handle 18 to make the pull handle 18 move inward again. Relying on the cooperation of the clamp 19 and the second spring 20, the pull handle 18 is locked and fixed for the second time. At this time, since the pull handle 18 continues to be pressed, the pull rope 17 will pull the rotating wheel 16 to rotate again, so that the cam 9 continues to rotate until the cam 9 drives the missing gear 12 to move and the missing gear 12 and the spur gear 13 are meshed with each other. At this time, the spur gear 13 will drive the rotating seat 5 to rotate, so that the magnetic suction bracket 6 flips downward. At the same time, the toggle member 22 will follow the cam 9 to move to the outside of the elastic sheet 21. At this time, the detection head 24 is used to determine the position of the needle, and then the moving device enables the magnetic suction frame 6 to adsorb the needle to complete the needle picking operation. After the needle is picked up, the pull handle 18 is reset. At this time, under the action of the scroll spring 11, the cam 9 will rotate and reset, so that the toggle frame pushes the elastic sheet 21 to move outward, releasing the lock on the sliding ring 8. Under the action of the first spring 10, the sliding ring 8 will slide upward and reset, so that the device returns to its initial state.

Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
