As an optimization solution, the first clamping part is further provided with a first clamping part anti-slip layer, and the second clamping part is further provided with a second clamping part anti-slip layer.

As an optimization solution, both the anti-slip layer of the first clamping part and the anti-slip layer of the second clamping part are anti-slip protrusions.

As an optimized solution, the direction of the aforementioned anti-slip protrusion is perpendicular to the axis of the clamping portion where it is located.

As an optimization solution, the aforementioned first handle is also provided with a first handle extension, the first handle extension is provided with a ratchet 1, and the handle 2 is also provided with a second handle extension , the extension part of the second handle part is provided with a ratchet two, and when the first clamping part engages with the second clamping part, the ratchet one is connected to the ratchet two.

As an optimized solution, the first ratchet has one tooth, and the second ratchet has multiple teeth.

As an optimized solution, the first ratchet has multiple teeth, and the second ratchet has one tooth.

As an optimization solution, there are two arc directions of the aforementioned arc portion.

The beneficial effects achieved by the present invention: during surgery, the arc part of the present invention can bypass the covering tissue or organ, so that the jaws (clamping part) can smoothly contact the organ that needs to be operated on, which is beneficial to the operation. On the other hand, since the present invention can bypass blocked tissues or organs, it can reduce the incision length of the patient's epidermis and reduce the pain of the patient.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

As shown in Figures 1 and 2: a medical curved bar pliers, including a clamp bar one 1 and a clamp bar two 4, one end of the clamp bar one 1 is provided with a first hand-held part 11, and the other end is connected to the first clamping part 2. One end of the rod 24 is connected to the second hand-held part 3, and the other end is provided with a second clamping part 41. The end of the first clamping part 2 is provided with a first clamping part protrusion 21, and the first clamping part protrudes 21. 21 connects the second clamping part 41, and the second handle part 3 is provided with the second handle part protrusion 31, and the second handle part protrusion 31 connects the pincer rod one 1, and the pincer rod one 1 and the pincer rod two 4 are both Including the bending portion 5 and the arc portion 6 , the bending direction of the bending portion 5 is on the plane where the first handle portion 11 and the second handle portion 3 are located.

As shown in Figure 3: the convex connecting parts of the above-mentioned two pliers rods are provided with pits, and the projections are provided with through holes, which are connected to the inside of the pits through pin shafts, so that when the clamping part is opened or closed by operating the handle ( Relative sliding occurs between the two pincer bars), the protrusion rotates in the pit with the connecting pin as the center, and the cross section of the pit is slightly larger than the cross section of the protrusion, so that the protrusion can have enough space for movement.

Combining FIG. 4 and FIG. 5 : the arc direction of the arc portion 6 is perpendicular to the bending direction of the bending portion 5 . Like this, there are two arc directions of the arc portion 6 (two are opposite), one is shown in Fig. 4, and the other is shown in Fig. 5, and in actual application, both arc directions can be made respectively, Form a pair of tools. It should be noted that when the clamping part is clamped or opened by the handle part, the two pliers rods slide axially. Therefore, in the actual manufacturing process, the arc size of the arc part 6 is controlled to avoid the If the clamping part is too large, the clamping part cannot be opened.

In order to enhance the reliability of the clamping part, the first clamping part 2 is also provided with a first clamping part anti-skid layer 22, and the second clamping part 41 is also provided with a second clamping part anti-skid layer 411, and the first clamping part 2 is also provided with a second clamping part anti-skid layer 411. Both the anti-slip layer 22 of the holding part and the anti-slip layer 411 of the second clamping part are anti-slip protrusions, and the direction of the anti-slip protrusions is perpendicular to the axis of the clamping part. This prevents the clamped object from coming off.

1, 2 and 7: the first handle 11 is also provided with a first handle extension 12, the first handle extension 12 is provided with a ratchet one 121, and the second handle 3 is also provided with a second handle part extension 32, the second handle extension part 32 is provided with a ratchet two 321, when the first clamping part 2 and the second clamping part 41 are engaged, the ratchet one 121 is connected to the ratchet two 321, and the ratchet One of the ratchets 121 and ratchet 2 321 has only a single tooth, and the other has multiple teeth, which is convenient for the two ratchets to be engaged. Can.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, some improvements and modifications can also be made. It should also be regarded as the protection scope of the present invention.
