AI Technical Summary

Problems solved by technology

The biopsy forceps adopts the upper and lower opening and closing of the forceps head to collect samples. The following problems exist in the collection process: because the surface of the cervix is ​​very slippery, especially for postmenopausal women, the cervix is ​​hard, and the biopsy forceps are more likely to slip off during the sampling process. Displacement, it is difficult to collect cervical biopsy accurately and accurately at one time, and often requires multiple operations to take out the required samples, which will cause low work efficiency for medical staff and increase the pain suffered by patients

Embodiment 1

[0033] Such as Figure 1-8 As shown, a cervical lesion tissue biopsy forceps capable of fixing anti-slipping and accurate positioning is characterized in that it includes a forceps body 1 and a positioning suction assembly 2 installed on the forceps body 1; the forceps body 1 includes a fixed handle 11, Movable handle 12, fixed pliers bar 13, sliding push rod 14, movable pliers head 15, and elastic pressing member 16;

[0034] The fixed pliers rod 13 is extended in the transverse direction, and the lateral rear end is fixedly connected to the upper part of the fixed handle 11. The fixed pliers rod 13 is provided with a fixed pliers extending vertically through the fixed pliers rod 13 near the lateral rear end of the fixed handle 11. The slotted hole 131 of the rod 13, the movable handle 12 is positioned at the lateral front of the fixed handle 11 and below the slotted hole 131, and the upper end of the movable handle 12 is fixedly provided with a connecting rod body 121 extend...

Embodiment 2

[0044] Such as Figure 9 As shown, the difference between this embodiment and Embodiment 1 is that the traction assembly includes a movable block 25 located between the guide block 21 and the movable handle 12 and below the fixed clamp rod 13 and fixedly connected to the pipe body 23, and a The connecting rod 26 whose one end is hinged with the movable block 25 and whose other end is hinged with the movable handle 12. This embodiment uses the connecting rod 23 to pull the tube body 23 to move back and forth relative to the guide block 21 (similar to the slider crank mechanism), so that the type of the tube body 23 is not limited to flexible pipes, other plastic hard tubes or metal tubes are also fine.

Abstract

The invention relates to the technical field of biopsy forceps, in particular to cervical lesion tissue biopsy forceps capable of being fixed, preventing slippage and accurately positioning. The cervical lesion tissue biopsy forceps comprise a forceps body and a positioning suction assembly installed on the forceps body; the forceps body comprises a fixed handle, a movable handle, a fixed forceps rod, a sliding push rod, a movable forceps head and an elastic jacking piece; the positioning suction assembly comprises a guide block, a suction nozzle and a pipe body, the tail end of the pipe body is connected with the negative pressure pump body, and the positioning suction assembly further comprises a traction assembly which is fixedly connected to the movable handle and located on the pipe body between the guide block and the fixed handle. According to the invention, the positioning suction assembly is added on the basis of existing biopsy forceps, a part needing to be collected is sucked and positioned through the suction nozzle, and in the shearing process of the movable forceps head, the sucked part is pulled backwards and fed into the shearing opening, so that living tissue is conveniently collected, and the biopsy forceps have the advantages of being fixed, resistant to skid, capable of accurately collecting samples; therefore, working efficiency is improved and the examination pain of the patient is reduced.

Description

technical field [0001] The invention relates to the technical field of biopsy forceps, in particular to a cervical lesion tissue biopsy forceps capable of fixing, preventing slippage and accurately positioning. Background technique [0002] Cervical biopsy is a biopsy of the cervix, that is, using biopsy forceps to take a small piece or a few pieces of tissue from the surface of the cervix for pathological examination to confirm the diagnosis. It is mostly used in suspicious cervical cancer or cervical smears. Cells, or suspected specific inflammation, such as cervical tuberculosis. Cervical biopsy can confirm the diagnosis and determine the treatment method. Cervical biopsy is a reliable basis for the diagnosis of cervical cancer. [0003] The patent number is "ZL201920285929.1", a disposable cervical biopsy forceps. The biopsy forceps includes a fixed handle, a movable handle, an elastic plate, a forceps rod, a push rod and a forceps head. The upper end of the fixed handl...
