In order to solve above-mentioned technical problem, the invention discloses a kind of seal wire being arranged in endoscope lock, connect seal wire contained structure including on base, movable clamping block, base, seal wire contained structure arranges seal wire locking stop and seal wire lock slots；Described base is provided with circular hole, circular hole and the pincers road junction shape adaptation of endoscope, is used for floor installation at the pincers road junction of endoscope；Described movable clamping block is provided with the double-pore structure being connected, and one of them hole is identical with the hole shape of base, and another hole is less than the circular hole of base, for base is locked in the pincers road junction of endoscope；Described seal wire locking stop and seal wire lock slots are for winding fixing seal wire.
In the present invention, described base is provided with chute, and movable clamping block is provided with limited block, and described limited block moves in chute, thus the position of restriction activity clamping block.
In the present invention, being provided with spring in described base, in a free state, on movable clamping block, less hole card is locked on the pincers road junction of endoscope spring, thus locking seal wire lock automatically；Spring under compression, on movable clamping block, align with the pincers road junction of endoscope by bigger hole, is used for installing or dismantle seal wire lock.
In the present invention, a side end face of described movable clamping block inserted base is provided with for pacifying spring-loaded projection.
In the present invention, in described seal wire contained structure, it is provided with the sealing cap passed for seal wire.
In the present invention, being provided with sealing cap in seal wire contained structure, seal cap and be contained in seal wire lock inside, lower end coordinates with the extruding of speculum forceps road junction, for the thrust that the fixing offer of seal wire lock is certain, provides sealing function for pincers road junction.
The side of movable clamping block inserted base is provided with breach, so that there is certain elasticity the two side of seal wire locking stop.When assembling with base, sliding everywhere in both sides, is reduced by the extruding on inclined-plane, then can cross, it is achieved assembling.
Another scheme of the present invention, described base is provided with chute, movable clamping block is provided with limited block, described limited block moves in chute, thus the position of restriction activity clamping block, it being provided with spring in described base, spring is in a free state, on movable clamping block, less hole card is locked on the pincers road junction of endoscope, thus locking seal wire lock automatically；Spring under compression, on movable clamping block, align with the pincers road junction of endoscope by bigger hole, is used for installing or dismantle seal wire lock.
The present invention is applied to speculum forceps road junction, seals pincers road and fixing seal wire, can be firmly fixed to speculum forceps road junction, it is achieved effectively seal, and can easily mount and dismount, facilitate one-handed performance during surgical.
The present invention is integrated with a movable fixture block, spring, base and sealing cap, whole seal wire lock fixing, seal, seal wire is locked as one.Can easily realize that seal wire is installed by one hand to lock and dismounting seal wire lock, convenient laborsaving.The cap that seals within Tong Shi is recessed pyramidal structure, is inserted in endoscope channel, more preferable than the sealing cap sealing effectiveness of general closed planar.
