[0002] Tweezers come in various materials, with stainless steel being a common choice. Stainless steel is durable, rust-resistant, and suitable for various environments, such as medical settings and laboratories. Doctors and nurses use tweezers to pick up cotton balls for disinfection or to remove foreign objects from wounds. The automatic rebound feature of spring-loaded tweezers speeds up the process, eliminating the need for manual adjustment of the grip. After each use, the tweezers automatically return to a position where they can grasp objects.
[0003] In existing technologies, some spring-loaded forceps require medical staff to hold them for extended periods and apply pressure to counteract the rebound force in order to grip the gauze. This keeps the hand muscles in a state of tension and contraction, which can lead to overwork and reduced work efficiency over time.
[0004] Therefore, in order to address the above shortcomings, this application proposes a spring-loaded tweezers to solve the aforementioned problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a spring-loaded tweezers, which aims to solve the problem that some spring-loaded tweezers in the prior art require holding the tweezers for a long time, causing the hand muscles to be in a tense state for a long time, resulting in excessive muscle fatigue and affecting work efficiency.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A spring-loaded forceps includes a sphere, with forceps rotatably connected to both the left and right ends of the sphere. A connecting plate is fixedly connected to the bottom end of one forceps, and a toothed plate is fixedly connected to the bottom end of the other forceps. Multiple toothed blocks are fixedly connected to the side of the connecting plate near the toothed plate. A connecting frame is fixedly connected to the right side of one forceps, and an elastic reset plate is fixedly connected to the top of the connecting frame. A serrated retaining plate is fixedly connected to the left side of the other forceps. A spring-loaded steel sheet is connected to the top of one forceps. Multiple massage components for massaging the patient are fixedly connected inside the sphere.
[0008] As a further description of the above technical solution:
[0009] The massage component includes multiple positioning posts, the exterior of which is fixedly connected to the interior of the sphere, and massage rollers are rotatably connected to the exterior of each positioning post.
[0010] As a further description of the above technical solution:
[0011] The exterior of each of the massage rollers is rotatably connected to the interior of the sphere, and a limiting opening is provided on the top side of the sphere;
[0012] As a further description of the above technical solution:
[0013] Anti-slip pads are fixedly connected to the opposite sides of the two tweezers, and multiple anti-slip textures are provided on the opposite sides of the two anti-slip pads.
[0014] As a further description of the above technical solution:
[0015] The toothed plate has multiple toothed grooves on its left side, and the toothed block matches the toothed grooves;
[0016] As a further description of the above technical solution:
[0017] The bottom side of the elastic reset plate has multiple V-shaped openings, and the elastic reset plate matches the serrated clamping plate.
[0018] As a further description of the above technical solution:
[0019] One of the tweezers has a T-shaped groove on its right side, one end of the spring steel sheet is slidably connected to the inside of the T-shaped groove, and the other end of the spring steel sheet is connected to the left side of the other tweezer.
[0020] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, when the two tweezers move to the same side, they will respectively drive the connecting plate and the toothed block to move to the same side. Then, the toothed block on the surface of the connecting plate abuts against the gauze, so that the position of the elastic reset plate and the sawtooth plate is adjusted according to the thickness of the gauze. Then the toothed block will abut against the gauze, so that it can be embedded in the interior of the toothed plate. Through the engagement of the elastic reset plate and the sawtooth plate, the gauze is fixed, and there is no need to apply pressure to clamp the gauze for a long time, reducing hand fatigue and thus improving work efficiency.
[0024] 2. In this utility model, by holding two anti-slip pads, the contact area with the hand is increased by utilizing the rubber material of the anti-slip pads and the anti-slip texture on the surface, thereby improving the anti-slip effect; and the arc surface at the top of the ball can press the accumulated fluid or pus under the patient's skin, while the massage wheel in the massage component can rotate with the movement of the ball when in contact with the patient's skin, playing a role in massage and promoting blood circulation.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1 to 3This utility model provides an embodiment of a spring-loaded forceps, comprising a sphere 1. The sphere 1, through its curved top surface, allows it to press on fluid or pus under the patient's skin. Forceps 2 are rotatably connected to both ends of the sphere 1, and the forceps 2 work together to grasp gauze. A connecting plate 3 is fixedly connected to the bottom end of one forceps 2, and the connecting plate 3 is welded to the forceps 2 to ensure long-term use and prevent breakage. A toothed plate 6 is fixedly connected to the bottom end of the other forceps 2. Multiple toothed grooves 7 are formed on the left side of the toothed plate 6. Multiple toothed blocks 4 are fixedly connected to the side of the connecting plate 3 near the toothed plate 6. The shape of the toothed grooves 7 is adapted to the toothed blocks 4, so that the gauze can be embedded inside the toothed plate 6 when grasping it. The toothed blocks 4 match the toothed grooves 7 to grasp the gauze, providing space for the gauze to be properly secured.
[0033] Reference Figures 2 to 4 One of the tweezers 2 has a connecting frame 8 fixedly connected to its right side. The top and right sides of the connecting frame 8 are open, forming a frame. An elastic reset plate 9 is fixedly connected to the top of the connecting frame 8. The elastic reset plate 9 is made of 65Mn spring steel, possessing elasticity and fatigue resistance. Multiple V-shaped openings 10 are provided on the bottom side of the elastic reset plate 9. A serrated clamping plate 11 is fixedly connected to the left side of the other tweezers 2. The elastic reset plate 9 matches the serrated clamping plate 11 and engages at the notch of the serrated clamping plate 11. The bottom side of the elastic reset plate 9 is slidably connected to the top side of the serrated clamping plate 11. The elastic design of the elastic reset plate 9 allows it to slide smoothly on the serrated clamping plate 11, thereby adjusting the angle between the two tweezers 2 to accommodate different thicknesses. The usable angle between the two tweezers 2 ranges from 0 to 30 degrees.
[0034] One of the tweezers 2 has a spring-loaded steel sheet 13 rotatably connected to its tip. The spring-loaded steel sheet 13 is made of copper alloy and has elastic recovery capability. The engaging force of the elastic reset plate 9 is greater than the elastic force of the spring-loaded steel sheet 13, allowing the elastic reset plate 9 to stably engage with the serrated clamping plate 11. A T-shaped groove 12 is provided on the right side of one of the tweezers 2. The T-shaped groove 12 is T-shaped with a protruding right end. One end of the spring-loaded steel sheet 13 is slidably connected inside the T-shaped groove 12. The T-shaped groove 12 restricts the spring-loaded steel sheet 13, allowing it to slide stably. The other end of the spring-loaded steel sheet 13 is connected to the left side of the other tweezers 2. The spring-loaded steel sheet 13 presses against the other tweezers 2, allowing the other tweezers 2 to squeeze the spring-loaded steel sheet 13, thus storing elastic potential energy in the spring-loaded steel sheet 13.
[0035] Furthermore, a guide plate 14 is fixedly connected to one end of the spring sheet 13. The guide plate 14 is used to guide the deformation of the spring sheet 13. The outside of the guide plate 14 is slidably connected to the inside of the T-shaped groove 12. The guide plate 14 can slide stably due to the restriction of the T-shaped groove 12.
[0036] Anti-slip pads 15 are fixedly connected to the opposite sides of the two tweezers 2. The anti-slip pads 15 are made of rubber, which is flexible and non-slip, making it easy to grip the two tweezers 2. Multiple anti-slip grooves 16 are formed on the opposite sides of the two anti-slip pads 15, and the depth of the anti-slip grooves 16 further improves the anti-slip effect.
[0037] The sphere 1 has multiple massage components fixedly connected inside, providing massage and blood circulation improvement functions. A limiting opening 17 is provided on the top side of the sphere 1 for aligning suture needles. The massage components include multiple positioning posts 18, all externally fixedly connected to the inside of the sphere 1. The positioning posts 18 are connected to the sphere 1 via welding, ensuring stable support. Massage rollers 5 are rotatably connected to the outside of each positioning post 18, providing a massage effect upon contact with the patient's skin. The massage rollers 5 are also rotatably connected to the inside of the sphere 1, restricting their rotation and ensuring stable rotation.
[0038] Working principle: Initially, the elastic reset plate 9 and the spring-loaded steel sheet 13 are in their natural state. When the user holds the ball 1 and applies external force to the tweezers 2, the two tweezers 2 slide towards each other. At this time, the elastic reset plate 9 will press against the other tweezer 2 and rotate and deform around one of the tweezers 2. Meanwhile, the connecting frame 8 and the serrated clamping plate 11 will slide towards each other until they engage. Then, the serrated clamping plate 11, through the notch at the top, presses against the elastic reset plate 9, allowing the elastic reset plate 9 to deform upwards under force. After reaching the desired position, the elastic reset plate 9 will return to its original position and engage with the serrated clamping plate 11. The locking force of the elastic reset plate 9 is greater than the rebound force of the spring-loaded steel plate 13, which keeps the two forceps 2 stationary. When the two forceps 2 move to the same side, the connecting plate 3 and the toothed block 4 also move to the same side. Then, the toothed block 4 on the surface of the connecting plate 3 presses against the gauze, so that the position of the elastic reset plate 9 and the serrated clamping plate 11 is adjusted according to the thickness of the gauze. Then the toothed block 4 will press against the gauze, so that it can sink into the toothed groove 7 opened in the toothed plate 6. Then, through the locking of the elastic reset plate 9 and the serrated clamping plate 11, the gauze is fixed, without the need for medical staff to apply pressure to clamp the gauze for a long time.
[0039] During use, by holding the two anti-slip pads 15, the rubber material of the anti-slip pads 15 and the anti-slip texture 16 on the surface are used to increase the contact area with the hand, thereby improving the anti-slip effect. In addition, during use, the arc surface at the top of the ball 1 can push down the accumulated fluid or pus under the patient's skin, and the massage roller 5 in the massage component can rotate with the movement of the ball 1 when in contact with the patient's skin, which plays a role in massaging and promoting blood circulation.
[0040] After use, by holding the elastic reset plate 9 and pulling it upward, the V-shaped opening 10 at the bottom of the elastic reset plate 9 is no longer engaged with the top of the serrated clamp plate 11. Then the spring steel sheet 13, which is in a compressed state, will reset and slide against another tweezer 2, causing the two tweezer 2 to slide to the opposite side and open, thus completing the reset of the two tweezer 2.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
