Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. It should be noted that unless otherwise explicitly stated or limited, the terms "mounted," "connected," and "disposed" are to be construed broadly and their meaning in the context of this patent may be understood by those skilled in the art as appropriate.

Referring to fig. 1-6, an ultrafine biopsy forceps comprises a handle 7, a spring tube 5 is arranged on one side of the handle 7, a forceps head mechanism is fixedly connected to one end of the spring tube 5, the forceps head mechanism comprises a forceps head frame 8, a pull rod frame 10 and two rotating plates 12, an arc-shaped groove 13 is formed on the upper surface of each rotating plate 12, a moving pin shaft 11 and a moving pin shaft hole which can be mutually clamped are respectively arranged on each rotating plate 12, a fixed pin shaft 9 and a clamping groove are integrally formed on the forceps head frame 8, a pull rod moving pin shaft hole with the specification matched with the moving pin shaft 11 is integrally formed on the pull rod frame 10, one end of the pull rod frame 10 passes through the clamping groove on the forceps head frame 8, the pull rod moving pin shaft hole on the pull rod frame 10, the moving pin shaft 11 on the rotating plates 12 and the moving pin shaft hole on the rotating plates 12 form clamping fit, and the fixed pin shaft 9 on the forceps head frame 8 is clamped in the arc-shaped groove 13 on the two rotating plates 12, when the pull rod frame 10 is pulled, the two rotating plates 12 can do opening and closing movement, the clamp heads 14 are fixedly connected to one sides of the two rotating plates 12, the rotating plates 12 enable the clamp heads 14 to be in a closed design through the arc-shaped grooves 13, cell tissues for biopsy sampling can be clamped, the phenomenon that the biopsy tissues fall off when the clamp head frame 8 exits from a focus is avoided, and the success effect of biopsy sampling is guaranteed;

circumference one side integrated into one piece of binding clip 14 has the cutter, and the cooperation design of cutter on binding clip 14 can be when carrying out biopsy cell tissue sample, can be quick cut the cell tissue of focus department, avoids biopsy cell tissue to be difficult for droing the phenomenon that appears tearing, has reduced patient's pain, has ensured biopsy forceps's result of use, satisfies medical personnel's user demand

The handle 7 comprises a core bar 1, sliding grooves 2 are formed in two sides of the core bar 1, a sliding ring 3 is connected in the sliding grooves 2 in a sliding mode, one end of the core bar 1 is fixedly welded with a spring tube 5, and the spring tube 5 is communicated with the core bar 1; through the design of the communication among the spring tube 5, the core bar 1 and the binding clip frame 8, the steel wire rope 4 can be directly connected with the pull rod frame 10 and the sliding ring 3, and the stability between the steel wire rope 4 and the sliding ring 3 as well as the pull rod 10 is ensured; the openings of the arc-shaped grooves 13 are opposite in direction, a boosting pipe 6 is fixed on one side of the sliding ring 3, one end of the boosting pipe 6 is bolted with a steel wire rope 4, the steel wire rope 4 penetrates through the spring pipe 5 to be bolted with the pull rod frame 10, and the steel wire rope 4 is pulled to enable the tong head 14 to do opening and closing movement.

The working principle is as follows: during the use, before the doctor uses biopsy forceps to carry out the sample of living cell, binding clip 14 belongs to the closure state, thereby can be directly stretch into focus department with pincers head frame 8 through the speculum pincers way, when needing to open binding clip 14, promote sliding ring 3 and move down in spout 2, then the compression of boosting tube 6, wire rope 4 moves down, thereby make pull rod frame 10 slide forward in binding clip frame 8, at this moment, rotor plate 12 rotates to both sides through arc 13, thereby make binding clip 14 open, when the doctor is pressing from both sides when getting the biopsy tissue, the hand loosens sliding ring 3, under the elasticity of spring 6, make wire rope 4 tensile, thereby drive pull rod frame 10 and upwards slide, and then make rotor plate 12 pass through arc 13 and make binding clip 14 closed.

The above, only be the embodiment of the preferred of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, which are designed to be replaced or changed equally, all should be covered within the protection scope of the present invention.
