Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and specifically relates to a disposable cervical biopsy forceps. Background Art

[0002] Cervical biopsy is the biopsy of the living tissue of the cervix, that is, taking a small piece or several pieces of tissue from the cervix for pathological examination to determine the diagnosis. The disposable cervical biopsy forceps have been widely used in clinical practice due to their advantages such as large sample volume, high biopsy accuracy, and little harm to patients.

[0003] Currently, in the prior art, in order to facilitate the upper jaw head to be pressed into the lower jaw head for tissue sampling, through holes are provided in the lower jaw head. Therefore, when in use, the sampled tissue is very easy to fall from the bottom through hole of the lower jaw head. In the existing sampling forceps, a tissue pocket is fixed in the lower jaw head. The disposable cervical biopsy forceps further include a tissue pocket, and the tissue pocket is connected below the lower jaw head and communicated with the lower jaw head. The tissue pocket is generally buckled in the lower jaw head.

[0004] However, after the existing disposable cervical biopsy forceps sample the living tissue, the living tissue falls into the through hole. When the user holds and presses the jaw head, if the user's hand loosens, the jaw head will accidentally open, and the tissue will fall out of the jaw head, thus affecting the use of the disposable cervical biopsy forceps. Therefore, in view of the above problems, a disposable cervical biopsy forceps is proposed. Summary of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art, the utility model provides a disposable cervical biopsy forceps.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: The disposable cervical biopsy forceps of the utility model include a biopsy forceps body; one end of the biopsy forceps body is connected with a connecting rod; the other end of the connecting rod is connected with a jaw head; the bottom of the biopsy forceps body is hinged with a movable handle; elastic plates are fixedly connected between the movable handle and the biopsy forceps body; fixed rods are fixedly connected to both sides of the biopsy forceps body; a telescopic column is fixedly connected to one side of the fixed rod; a first return spring is sleeved and connected to the surface of the telescopic column; one end of the telescopic column is fixedly connected with an inclined block; an auxiliary rod is fixedly connected to one side of the movable handle; an inclined connecting block is fixedly connected to one end of the auxiliary rod; the inclined connecting block is used in cooperation with the inclined block.

[0007] Preferably, an auxiliary block is fixedly connected to one side of the inclined block; a pull column is fixedly connected to one side of the auxiliary block; the surface of the pull column is slidably connected with the fixed rod.

[0008] Preferably, a second return spring is sleeved and connected to the surface of the pull column; the second return spring is located between the fixed rod and the auxiliary block.

[0009] Preferably, a blocking nut is threadedly connected to one end of the pull column; the blocking nut is circular.

[0010] Preferably, an anti-slip nut is rotatably connected to one end of the connecting rod; the other side of the anti-slip nut is rotatably connected to the sampling forceps body.

[0011] Preferably, the fixed rod is in an L shape, and the length of the inclined connecting block is greater than the length of the inclined block; the moving distance of the inclined connecting block is the same as the moving distance of the clamping of the forceps head.

[0012] Preferably, the number of the fixed rod, the telescopic column, the inclined block, the inclined connecting block and the auxiliary rod is two, and the fixed rod, the telescopic column, the inclined block, the inclined connecting block and the auxiliary rod are symmetrically distributed on both sides of the sampling forceps body.

At the same time, the movable handle 102 drives the auxiliary rod 109 to move, the auxiliary rod 109 drives the inclined connecting block 110 to move, the inclined connecting block 110 compresses the inclined block 108, and the inclined block 108 compresses the first return spring 107. When the inclined connecting block 110 moves to the other side of the inclined block 108, under the action of the first return spring 107, the inclined block 108 resets, and the inclined block 108 limits the inclined connecting block 110, thereby fixing the movable handle 102, thereby fixing the forceps head 101, thereby reducing the possibility of the living tissue falling off and improving the practicability of the cervical biopsy forceps.

[0027] Further, as Figure 4 and Figure 5 shown, one side of the inclined block 108 is fixedly connected with an auxiliary block 2; one side of the auxiliary block 2 is fixedly connected with a pull column 201; the surface of the pull column 201 is slidably connected with the fixed rod 104; during operation, after taking out the living tissue, the user pulls the pull column 201 on the fixed rod 104, the pull column 201 drives the auxiliary block 2 to move, the auxiliary block 2 drives the inclined block 108 to move, and under the action of the elastic plate 103, the movable handle 102 resets, the forceps head 101 opens, and the living tissue is taken off for the next operation.

[0028] Further, as Figure 5As shown, a second return spring 3 is sleeved and connected to the surface of the pull post 201; the second return spring 3 is located between the fixed rod 104 and the auxiliary block 2; during operation, the auxiliary block 2 compresses the second return spring 3, and after the pull post 201 is released, under the action of the second return spring 3, the auxiliary block 2 is reset.

[0029] Furthermore, as Figure 5 shown, one end of the pull post 201 is threadedly connected with a blocking nut 4; the blocking nut 4 is circular; during operation, the blocking nut 4 blocks the pull post 201, reducing the detachment of the pull post 201 from the fixed plate, thereby reducing the influence on the operation of the pull post 201.

[0030] Furthermore, as Figure 2 shown, one end of the connecting rod 105 is rotatably connected with an anti-slip nut 5; the other side of the anti-slip nut 5 is rotatably connected with the sampling forceps body 1; during operation, the anti-slip nut 5 is provided to facilitate the user's rotation, reduce sliding, and facilitate the user's replacement.

[0031] Working principle: The user holds the movable handle 102, and the movement of the movable handle 102 drives the clamping head 101 to clamp and take the living tissue in the patient's cervix. At the same time, the movable handle 102 drives the auxiliary rod 109 to move, the auxiliary rod 109 drives the inclined connecting block 110 to move, the inclined connecting block 110 compresses the inclined block 108, and the inclined block 108 compresses the first return spring 107. When the inclined connecting block 110 moves to the other side of the inclined block 108, under the action of the first return spring 107, the inclined block 108 resets, and the inclined block 108 limits the inclined connecting block 110, thereby fixing the movable handle 102, thereby fixing the clamping head 101, thereby reducing the possibility of the living tissue falling, improving the practicability of the cervical living tissue sampling forceps. After taking out the living tissue, the user pulls the pull post 201 on the fixed rod 104, the pull post 201 drives the auxiliary block 2 to move, the auxiliary block 2 drives the inclined block 108 to move, under the action of the elastic plate 103, the movable handle 102 resets, the clamping head 101 opens, and the living tissue is taken off for the next operation. The auxiliary block 2 compresses the second return spring 3, and after the pull post 201 is released, under the action of the second return spring 3, the auxiliary block 2 is reset. The blocking nut 4 blocks the pull post 201, reducing the detachment of the pull post 201 from the fixed plate, thereby reducing the influence on the operation of the pull post 201. The anti-slip nut 5 is provided to facilitate the user's rotation, reduce sliding, and facilitate the user's replacement.
