Among the present embodiment, described depression bar 81 has spaced apart Part I and Part II, and connects the coupling part of Part I and Part II, and this Part I, Part II and coupling part cooperatively interact and make depression bar 81 form a class U font structure; Part I and coupling part are located in the draw-in groove of described fixed handle 10; One end of Part I is rotationally connected by described depression bar steady pin 811 and fixed handle 10; One end of Part II is provided with described groove 812; This Part I is provided with a projection, and this projection and last item 831 cooperatively interact, and in the time that shifting block 83 is positioned at primary importance, last item 831 separates with protruding, and last item 831 is separated with depression bar 81, depression bar 81 on carry state; When shifting block 83 is positioned at the second position, last item 831 slides into high spot and depresses projection depression bar 81 is moved down, and depression bar 81 is in pressed status.
Among the present embodiment, on described claw beam 30, have a water supply flow to into perfusing hole 31; Described push rod 40 is socketed in claw beam 30 and can slides in the interior front and back of claw beam 30, and gap between push rod 40 and claw beam 30 formed aquaporin; Gap between described fixed pliers head 60 and movable binding clip 70 forms the outlet flowing out for current, like this, while needing to rinse in operation, the flushing liquors such as normal saline can enter and flow out operative region is cleaned from binding clip from perfusing hole, and claw beam 30 itself becomes current perfusion channel, does not need additionally to add perfusion equipment, volume is little, surgical wound surface is little, and it is convenient to rinse, and surgical field of view is clear.
Among the present embodiment, described perfusing hole 31 is provided with the pouring stopper 32 that can install and remove, while not needing to rinse, perfusing hole can be sealed, and prevents that introduced contaminants from polluting engaging clamp inside.
Among the present embodiment, described push rod 40 is provided with a chute 41, in described claw beam 30, be provided with a baffle plate 33, while slip in push rod 40 front and back, this baffle plate 33 can be in the interior slip of chute 41, the sliding distance of restriction push rod 40, thereby the maximum folding angle of control activity binding clip 70, preventing that movable binding clip 70 from excessively flicking brings unnecessary wound to patient, and this baffle plate 33 is connected by an elastic component 42 between cell wall afterwards with chute 41, this elastic component 42 is for example spring, unclamp flexible handle after this elastic component 42 can impel push rod 40, flexible handle 20 and movable binding clip 70 to reset.
As required, between push rod 40 and flexible handle 20, a swinging plate can also be set, this swinging plate is fixed in flexible handle 20 by handle steady pin 50, and this swinging plate is resisted against on push rod 40, drive swinging plate to rotate to promote push rod 40 by flexible handle 20 and slide, more sensitive.
Among the present embodiment, described movable binding clip 70 is rotationally connected by binding clip steady pin 61 with fixed pliers head 60; Described push rod 40 front ends are provided with binding clip moving pin 43, this binding clip moving pin 43 is equipped with in the binding clip slotted eye 71 on being opened in movable binding clip 70 and can in this binding clip slotted eye 71, slides, like this, when actual use, can prevent that movable binding clip 70 is stuck on the one hand, switching that on the one hand also can promotion activity binding clip 70.
Among the present embodiment, described engaging clamp is made up of medical stainless steel material, convenient cleaning and high-temperature sterilization.
The on-the-spot occupation mode of the present invention is as follows:
The engaging clamp of the present embodiment in use, only need clutch flexible handle 20, flexible handle 20 rotates and promotes push rod 40 to front slide, now elastic component 42 is subject to force compresses, push rod 40 is during to front slide, and binding clip moving pin 43 promotion activity binding clips 70 rotate taking binding clip steady pin 61 as axle, and now binding clip moving pin 43 slides in binding clip slotted eye 71, one side prevents stuck, also makes on the one hand movable binding clip closed downwards; Unclamp after flexible handle 20, elastic component 42 pressures disappear, and elastic component 42 resets, and promote push rod 40 and slide backward, thereby promote that flexible handle 20 resets and movable binding clip 70 opens under the effect of elastic component 42.
While needing movable binding clip 70 to continue closure with clamping tissue, shifting block 83 is pushed into primary importance forward, now on depression bar 81, carry, the pawl structure of spacer 82 is connected on the axis 813 of depression bar 81 and forms engagement, pawl structure makes spacer 82 can only continue cannot to slide outward toward the interior slip of groove 812, flexible handle 20 can only continue closure and cannot open, movable binding clip 70 also cannot open, thereby sting tight piece of tissue, now operator does not need firmly to pinch for a long time handle and tissue holder can be taken out; While not needing clamping tissue, shifting block 83 is pushed into the second position backward, now depression bar 81 presses down, the pawl structure of spacer 82 and axis 813 are in released state, spacer 82 can be free to slide in groove 812, now flexible handle 20 can freely open and closure, and movable binding clip 70 also can freely open and closure, facilitates operation technique.
The above, only for preferred embodiment of the present invention, therefore can not limit according to this scope of the invention process, the equivalence of doing according to the scope of the claims of the present invention and description changes and modifies, and all should still belong in the scope that the present invention contains.
