[0023] The following embodiments further illustrate the content of the present invention, but should not be construed as a limitation to the present invention. Without departing from the spirit and essence of the present invention, any modification or replacement made to the methods, steps or conditions of the present invention shall fall within the scope of the present invention.

[0024] Please refer to Figure 1 , a pair of medical forceps with an anti-fatigue auxiliary device, the medical forceps 2 includes a clamping end 201 and a connecting end 202, and the pair of medical forceps with an anti-fatigue auxiliary device further includes:

[0025] A guide member 1. The guide member 1 is disposed on the outer surface of the middle parts of the two clamping arms of the medical forceps 2. The guide member 1 includes a guide inclined surface 101. The fixed side of the guide inclined surface 101 is connected to the clamping arm of the medical forceps 2. The included angle α between the guide inclined surface and the plane where the clamping arm of the medical forceps is located in the direction of the connecting end 202 is an acute angle;

[0026] A driving ring 3. The driving ring 3 is sleeved on the guide inclined surface and the driving ring 3 slides on the guide inclined surface 101;

[0027] A handle 4. The handle 4 includes a thumb-holding section 401, an elastic connecting section 402 and a four-finger holding section 403 connected in sequence. The end of the four-finger holding section 403 is fixedly connected to the driving ring 3, and the end of the thumb-holding section 401 is detachably connected to the connecting end 202 of the medical forceps 2.

[0028] The design of the handle 4 enables the user to drive the opening and closing of the medical forceps through the natural movements of the thumb and four fingers. When the user tightly holds the handle 4 with the four fingers and the thumb, the four-finger holding section 403 will be squeezed inward. Through the sliding of the driving ring 3 on the guide inclined surface 101, since the guide inclined surface gradually rises from the clamping end 201 of the medical forceps 2 to the connecting end 202, the two clamping arms of the medical forceps 2 are pushed closer to achieve the clamping action. On the contrary, when the user relaxes the four fingers, the elasticity of the elastic connecting section 402 will cause the four-finger holding section 403 to open outward, the driving ring 3 slides downward accordingly, and the two clamping arms of the medical forceps 2 will also separate accordingly to complete the releasing action.

[0029] Specifically, the guide inclined surface can be solid or there is a space for accommodating fingers between the guide inclined surface and the clamping arm.

[0030] Such as Figure 2As shown, in some embodiments, a thread 4011 is provided at the end of the thumb-holding section 401, a threaded hole 2021 matching the thread is provided at the connecting end 202, and the thumb-holding section 401 is rotatably connected to the elastic connecting section 402.

[0031] When it is necessary to disassemble the handle, simply rotate the thumb-holding section 401 to separate the thread 4011 on the end of the thumb-holding section 401 from the threaded hole 2021 of the connecting end 202, and the handle 4 can be easily removed.

[0032] When the handle 4 is removed, the user can also directly use the medical forceps as a conventional tool and directly operate the clamping arms of the medical forceps through the thumb and index finger for clamping and releasing actions. This design not only meets the user's need for medical forceps with an anti-fatigue auxiliary device but also retains the independent use function of the medical forceps itself, making the device more flexible and adaptable in practical applications.

[0033] In some embodiments, as Figure 4 shown, the position of the guide member 1 is closer to the clamping end 201. In this way, when the handle 4 is removed, the user can directly use the medical forceps through the thumb and index finger, and the guide member 1 does not interfere with the placement position of the fingers, which is more in line with the traditional usage habit.

[0034] In some embodiments, as Figure 3 shown, the guide member 1 further includes a baffle 11. The baffle 11 is connected to the outside of the guide inclined surface 101. The baffle 11 is arranged parallel to the guide inclined surface 101. A gap for the driving ring to slide is left between the baffle 11 and the guide inclined surface 101. The inclined surface 101 and the clamping arm are fixedly connected through a fixed surface, and the fixed edge is formed on the fixed surface.

[0035] The design of the baffle 11 further enhances the sliding stability of the driving ring 3 on the guide inclined surface 101, preventing the driving ring 3 from shifting or jamming due to lateral force during the sliding process. At the same time, the baffle 11 also plays a certain role in dust prevention and protection, avoiding dust or fine substances from entering the sliding gap between the guide inclined surface and the driving ring, and ensuring the smooth operation of the device and the reliability of long-term use.

[0036] Further, an arc surface 102 is formed between the guide member 1 and the clamping arm of the medical forceps.

[0037] When the handle is removed, the user also operates by placing the thumb and index finger on the baffle 11 or the arc surface 102. Anti-slip patterns are provided on the baffle 11 and the arc surface 102, and these patterns increase the friction between the finger and the baffle, preventing slipping during the operation.

[0038] In some embodiments, to further enhance the user experience and the comfort of operation, such as Figure 1 as shown, a series of grooves matching the shape of four fingers are provided on the surface of the four-finger gripping section 403. These grooves can not only provide a conforming gripping feeling according to the natural bending shape of the user's fingers, but also increase the friction between the fingers and the gripping section to a certain extent, prevent slipping during operation, and improve the stability and precision of operation.

[0039] Meanwhile, in some embodiments, considering the pressure and discomfort that may be caused to the thumb web during long-term use, a soft gripping pad is provided at the thumb web gripping end 401. The gripping pad is made of medical-grade silicone material, has good elasticity and durability, can effectively relieve the fatigue of the thumb web during long-term gripping, and at the same time provides a comfortable gripping experience.

[0040] In some embodiments, a counterweight 2022 is added to the connecting end of the medical forceps. This counterweight design can balance the overall weight of the medical forceps, enabling medical workers to operate the medical forceps more labor-saving and stably during use, and further reducing the fatigue during long-term surgical operations. The selection of the counterweight material should consider its weight, corrosion resistance, and its impact on the overall performance of the medical forceps to ensure the safety and reliability of the medical forceps during use.

[0041] The anti-fatigue assist device of the present application can also be used on medical scissors. The specific principle is as Figure 5 shown. A medical scissors with an anti-fatigue assist device, the medical scissors 5 includes a scissor head and scissor handles, and a spring 6 is also installed between the two scissor handles. Similar to the design of the medical forceps, the anti-fatigue assist device includes a driving ring 3 and a handle 4. The driving ring is sleeved between the two scissor handles and can slide along the scissor handles. One end of the handle is fixedly connected to the driving ring 3, and the other end is fixedly connected to one of the scissor handles. When a medical worker needs to use the medical scissors with an anti-fatigue assist device, just place the thumb and four fingers on the thumb web gripping section 401 and the four-finger gripping section 403 respectively, and gently grip. As the four fingers are squeezed inward, the driving ring 3 will slide on the scissor handles, causing the two scissor heads to gradually close and complete the cutting action. On the contrary, when the medical worker relaxes the four fingers, the rebounding force of the spring 6 will cause the scissor heads to automatically open, and at the same time the driving ring and the handle will also reset, preparing for the next cutting operation. Similar to the design of the medical forceps, the handle of the medical scissors also uses the natural movements of the thumb web and four fingers as the driving force, and through the sliding of the driving ring 3 on the scissor handles, the cutting and resetting actions of the scissors are realized. This design effectively reduces the hand fatigue of medical workers when using scissors for a long time.

[0042] In summary, the medical forceps or medical scissors with an anti-fatigue auxiliary device provided by the present utility model effectively reduce the fatigue of medical workers during long-term surgical operations, improve the stability and comfort of surgical operations, through reasonable mechanical structure design, detachable connection structure and anti-slip texture. At the same time, the device also has good applicability and flexibility, and can meet the usage requirements of different medical workers.

[0043] Although the present utility model has been described in detail in the above text with general descriptions, specific embodiments and experiments, on the basis of the present utility model, some modifications or improvements can be made to it, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection required by the present utility model.
