[0033] For details, see Figure 2 and Figure 3 Compared with the traditional biopsy forceps, the clamping part of the biopsy forceps is divided into an outer clamp and an inner clamp 4. The inner clamp 4 is in the middle of the outer clamp, and the surface of the outer clamp is relatively smooth. In this way, when performing cervical biopsy, the outer clamp can protect the tissue in the cervix, avoid damage, and improve the patient's satisfaction. In addition, the biopsy forceps can simultaneously pull the first pull rod 2 in the clamp body 1 and a plurality of second pull rods 20 arranged in pairs through the movable handle 6, so that the outer clamp and the inner clamp 4 can move forward at the same time. The front end of the outer clamp is smooth and is used for preliminary biting of the cervical part where the tissue needs to be grasped, while the inner clamp 4 grasps the tissue through the blades 5 arranged toward each other at the front clamping part. Through the combination of the inner and outer clamps, the cervical tissue can be effectively grasped, thereby providing an effective guarantee for the subsequent smooth completion of the tissue biopsy.

[0034] As an optional implementation, in some embodiments, the outer surface of the clamp body 1 is covered with an outer sheath 9. The outer sheath 9 can be made of a soft material, such as medical plastic or rubber, so that on the one hand, the clamp body 1 can be protected from damage, and on the other hand, when the clamp body 1 enters the cervix, it plays a role in protecting the patient's cervical tissue.

[0035] As an optional implementation, in some embodiments, an elastic strip 8 is provided between the fixed handle 7 and the movable handle 6. The elastic strip 8 is in an inverted V shape between the fixed handle 7 and the movable handle 6. When the doctor releases the movable handle 6, the elastic strip 8 can automatically reset the movable handle 6 due to its elasticity, thereby restoring the clamp to its original position.

[0036] As an optional implementation, in some embodiments, the outer surface of the movable handle 6 is provided with anti-slip grooves 10 near its lower end. In this way, when the doctor holds the biopsy forceps, the friction between the palm and the movable handle 6 can be increased to avoid failure due to slipping during operation.

[0037] As an optional implementation, in some embodiments, the fixed handle 7 has a finger placement portion 11 and a through hole 12, and the through hole 2 is located below the finger placement portion 11. The shape of the finger placement portion 11 is adapted to the index finger, middle finger, and ring finger, and the size of the through hole 12 can accommodate four fingers other than the thumb to pass through at the same time, so that the doctor can hold the biopsy forceps according to the actual operation requirements or the doctor's own habits, so that the process of grabbing cervical tissue is smoother and smoother, thereby improving the success rate.

[0038] As an optional implementation, in some embodiments, the plurality of external clamps include an upper clamp 13 and a lower clamp 14, and the outer side of the upper clamp 13 and the outer side of the lower clamp 14 are both rounded. The external clamp is composed of an upper clamp 13 and a lower clamp 14, and the outer side of the upper clamp 13 and the lower clamp 14 are both rounded, and the whole is in the shape of a spoon. When the upper clamp 13 and the lower clamp 14 are closed, they are staggered to achieve the effect of cutting cervical tissue, so that it is not easy to cause damage to the cervical tissue. According to actual needs, it can also be replaced with a left clamp and a right clamp or increase a left clamp and a right clamp.

[0039] As an optional implementation, in some embodiments, the shape of the blade 5 is triangular. The blades 5 are arranged in a row and have a serrated structure as a whole, which makes it easier to grasp cervical tissue.

[0040] As an optional implementation, in some embodiments, the material of the clamp body 1 is stainless steel. The clamp body 1 is made of high-quality stainless steel, and its surface is smooth and easy to clean and disinfect, meeting medical requirements.

[0041] As an optional implementation, in some embodiments, the length of the clamp body 1 is 17-19 cm, wherein the clamp body 1 of this length can meet most requirements for grasping cervical tissue, but can be adjusted according to actual conditions to meet the requirements for grasping cervical tissue.

[0042] Working principle: When in use, the doctor's hand passes through the through hole 12 or the finger is placed on the finger placement part 11 to hold the fixed handle 7 and extend the forceps body 1 into the cervix, and move it to the part where the cervical tissue needs to be grasped. In this process, the outer forceps 4 are spoon-shaped and smooth in appearance, so it is not easy to cause damage to the cervical tissue, reducing the pain of the patient and improving satisfaction. When moving to the grasping position, the palm of the hand pinches the movable handle 6, so that the rotating shaft 3 rotates counterclockwise to move the pull rod 2 backward, and then the upper forceps 13, the lower forceps 14 and the inner forceps 4 move forward. The upper forceps 13 and the lower forceps 14 are used to initially bite the cervical part where the tissue needs to be grasped, and the inner forceps 4 grasps the cervical tissue through the blade 5. After the grasping is completed, the forceps body 1 is moved out of the cervix, and the movable handle 6 is released to restore the biopsy forceps to its original state. The operation is simple and convenient.

[0043] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0044] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable ordinary technicians in the field to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model.
