An endoscopic wire clamping device as shown in fig. 1-2, comprising: the wire clamping device comprises a clamping plate 20 for clamping a wire 10, a bottom plate 30 for guiding and limiting the clamping plate 20, a pulling plate 40 for pulling the clamping plate 20 and enabling the clamping plate 20 to move along the guiding direction of the bottom plate 30 so as to clamp or release the clamping plate 20, and a driving piece 50 for driving the pulling plate 40 to act.

The clamping device is used for clamping the tail end of the snake bone pipe to fix the snake bone pipe, so that the tail end of the snake bone pipe is kept unchanged on the premise that the front end bending part is smoothly bent, and the tail end of the snake bone pipe is prevented from being elastically deformed. Specifically, the present embodiment causes the clamping plate 20 to clamp or unclamp the wire 10, i.e., the end of the snake bone canal, by the cooperation of the base plate 30, the pulling plate 40 and the clamping plate 20. An operator operates the driving part 50 to enable the pulling plate 40 to pull the clamping plate 20 along the guiding direction of the bottom plate 30, so that the clamping plate 20 is displaced, and the clamping plate 20 clamps the wire 10 in the displacement process through the limit of the bottom plate 30; on the contrary, when the wire 10 needs to be loosened, the driving member 50 is operated to move the pulling plate 40 in the opposite direction, so as to drive the clamping plate 20 to displace, and the clamping plate 20 loosens the wire 10 during the displacement process through the limit of the bottom plate 30.

As shown in fig. 3, the base plate 30 includes a stopper 31 for guiding and stopping the chucking plate 20; the limiting portion 31 comprises two first through grooves 311 matched with the thickness of the clamping plate 20 and used for inserting the clamping plate 20, and a horn-shaped opening 312 used for loosening the clamping plate 20, wherein the horn-shaped opening is formed in two free ends of the first through grooves 311. The two first through grooves 311 are arranged in parallel at intervals and are used for inserting the pair of clamping plates 20, and the trumpet-shaped opening 312 is arranged at the free end of the two first through grooves 311, so that when the clamping plates 20 are displaced and move towards the direction of the first through grooves 311, the clamping plates 20 clamp the wires 10; conversely, when the clamp plate 20 is displaced in the direction of the flared opening 312, the clamp plate 20 opens at the flared opening 312, releasing the wire 10.

As shown in fig. 1 and fig. 4, the driving member 50 of the present embodiment is a screw, and the pulling plate 40 is provided with a threaded hole 41 that is screwed into the screw. That is, the rotational movement of the screw is converted into the linear movement of the pulling plate 40 to pull the clamping plate 20 to be displaced. When the screw rod is rotated to a certain direction, the pulling plate 40 moves linearly towards the head direction of the screw rod, and the clamping plate 20 is pulled to clamp the wire 10; on the contrary, when the screw rod is rotated in the opposite direction, the pulling plate 40 moves linearly toward the direction of the clamping plate 20, so as to drive the clamping plate 20 to move to the flared opening 312, and loosen the wire 10. In addition, in order to make the screw rotate, the pulling plate 40 does linear motion instead of the screw, so the screw of the present embodiment is configured such that the end of the screw abuts against the clamping plate 20, and the screw is limited, thereby preventing the screw from generating linear motion when the screw rotates.

In other embodiments, the driving member 50 and the pulling plate 40 can be a screw nut pair, the driving member 50 is a screw, and the pulling plate 40 is a nut engaged with the screw. Alternatively, the connection may be made using a spring or the like capable of reciprocating motion.

As shown in fig. 4, a second through slot 42 is disposed on the pulling plate 40 for inserting and matching with the bottom plate 30 and limiting and guiding the pulling plate 40. That is, the slotting direction of the second through slot 42 is matched with the linear motion direction of the pulling plate 40, so that when the pulling plate 40 moves linearly, the second through slot 42 is in sliding fit with the bottom plate 30 along the slotting direction of the second through slot 42, and a certain limiting and guiding effect is exerted on the pulling plate 40.

In this embodiment, the pulling plate 40 is a U-shaped pulling plate 40, the clamping plate 20 is disposed between two opposite side edges, the two opposite side edges of the U-shaped pulling plate 40 are connected to the clamping plate 20, the number of the second through grooves 42 is two, and the two second through grooves 42 are symmetrically disposed on the two opposite side edges of the U-shaped pulling plate 40. And the threaded hole 41 is arranged on the bottom edge of the U-shaped pulling plate 40.

In the present embodiment, the pulling plate 40 and the clamping plate 20 are connected by bolts, i.e. the bolts pass through the pulling plate 40 and the clamping plate 20 and are connected. In other embodiments, it may be pinned or welded or riveted.

As shown in fig. 5, the clamping plate 20 includes a connecting plate 21 connected to the pulling plate 40, and a clamping head 22 for clamping the wire 10. The connecting plate 21 includes a third through groove 211 cooperatively connected with the base plate 30, and a fourth through groove 212 for giving way to the wire 10, and when the endoscope wire clamping device of the present embodiment is used, the wire 10 passes through the fourth through groove 212.

Because the wire 10 comprises the snake bone canal steel wire 11 and the sleeve 12 sleeved outside the snake bone canal steel wire 11, the chuck 22 in the embodiment is a soft chuck with elasticity, and the adjustment of clamping tightness is realized by utilizing the powerless characteristic of a soft material, so that the motion capability of the snake bone canal steel wire 11 is ensured while the sleeve 12 is clamped. The cartridge 22 may be a silicone cartridge, a rubber cartridge, or a sponge cartridge.

Since the pulling plate 40 pulls the clamping plate 20 to move so as to clamp or loosen the wire 10, in order to ensure that the clamping and loosening actions of the clamping plate 20 are smoothly performed, the connecting plate 21 according to the present embodiment is an elastic plate, that is, when the wire is pulled by the pulling plate 40 and is subjected to the limiting action of the bottom plate 30, the wire 10 can be clamped or loosened. The connecting plate 21 of the present embodiment is a stainless steel plate, and a 302 stainless steel plate is used, which not only ensures the strength of the connecting plate 21, but also ensures certain elasticity.

As shown in fig. 1 and fig. 6, the present embodiment further includes a handle 60, and the clamp plate 20 is fixedly connected to the handle 60. The bottom plate 30 is further provided with a yielding portion 32 for being connected with the handle 60 through a bolt, and the yielding portion 32 is a through hole or a through groove.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
