Being butted on flexible handle 20, push rod 40 front end connects movable binding clip 70；Described flexible handle 20 opens and Guan Bi
Movable binding clip 70 can be driven to open and Guan Bi；Also including a lockable mechanism 80, this lockable mechanism 80 includes:
Depression bar 81, described fixed handle 10 part is provided with the draw-in groove that Open Side Down, and this depression bar 81 is connected to this
It is rotationally connected with fixed handle 10 in draw-in groove and by depression bar steady pin 811, and this depression bar 81 can carry shape upper
Change between state and pressed status；Depression bar 81 lower end offers the groove 812 that Open Side Down and left and right is through, groove
The opening part of 812 is provided with the axis 813 connecting two cell walls；
Spacer 82, is fixed in flexible handle 20, and the free-end of spacer 82 is positioned at the groove 812 of depression bar 81
In and be positioned on axis 813；The lower periphery of spacer 82 is provided with pawl structure；Axis 813 and pawl structure
Cooperate and can change between engagement and released state；
Shifting block 83, is socketed on outside fixed handle 10 and by shifting block steady pin and fixed handle 10 and depression bar 81
Connecting, this shifting block steady pin is equipped with in the slide opening being opened on fixed handle 10 and depression bar 81 and can be
Slide in slide opening, make this shifting block 83 can slide between primary importance and the second place along fixed handle 10；This group
A last item 831 that can press depression bar 81 it is additionally provided with on block 83；When shifting block 83 is positioned at primary importance, last item 831
Separating with depression bar 81, depression bar 81 is in the state of putting forward, and axis 813 and pawl structure are in engagement, fixed
In bit slice 82 can continue to stretch into groove 812 but can not skid off, flexible handle 20 can continue Guan Bi but can not open
(as shown in Figure 1)；When shifting block 83 is positioned at the second place, last item 831 is pressed downward against dynamic pressure bar 81, depression bar 81
Being in pressed status, axis 813 and pawl structure are in released state, and spacer 82 can stretch into and skid off groove
812, flexible handle 20 can freely close and open (as shown in Figure 2).
Among the present embodiment, described depression bar 81 has spaced apart Part I and Part II, and connects
Part I and the coupling part of Part II, this Part I, Part II and coupling part cooperate and make
Depression bar 81 forms a class U-shaped structure；The draw-in groove of described fixed handle 10 is located in Part I and coupling part
In；One end of Part I is rotationally connected with fixed handle 10 by described depression bar steady pin 811；Second
/ one end is provided with described groove 812；This Part I is provided with a projection, and this projection is mutual with last item 831
Coordinating, when shifting block 83 is positioned at primary importance, last item 831 separates with projection, makes last item 831 and depression bar 81
Separating, depression bar 81 is in the state of putting forward；When shifting block 83 is positioned at the second place, last item 831 slides into high spot
And depress projection depression bar 81 is moved down, depression bar 81 is in pressed status.
Among the present embodiment, described claw beam 30 has the perfusing hole 31 that a water supply stream enters；Described push rod 40
In being socketed on claw beam 30 and gap between slide anteroposterior, and push rod 40 and claw beam 30 can constitute in claw beam 30
Cross aquaporin；Gap between described fixed pliers head 60 and movable binding clip 70 constitutes the delivery port flowed out for current,
So, when needing in operation to rinse, it is right that the flushing liquor such as physiological saline can enter from perfusing hole and flow out at binding clip
Operative region is carried out, and claw beam 30 itself becomes current perfusion channel, it is not necessary to additionally add perfusion equipment,
Volume is little, and 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 of energy mounting or dismounting, it is not necessary to can during flushing
Perfusing hole is sealed, prevents introduced contaminants from polluting inside engaging clamp.
Among the present embodiment, described push rod 40 is provided with a chute 41, is provided with a baffle plate 33 in described claw beam 30,
During push rod 40 slide anteroposterior, this baffle plate 33 can slide in chute 41, limits the sliding distance of push rod 40, from
And the maximum folding angle of control activity binding clip 70, preventing movable binding clip 70 from excessively flicking, bring patient need not
It is connected by an elastic component 42 between the wound wanted, and this baffle plate 33 with cell wall after chute 41, this elastic component
42 for example, springs, after unclamping flexible handle, this elastic component 42 can promote push rod 40, flexible handle 20 and activity
Binding clip 70 resets.
As required, can also arrange a swinging plate between push rod 40 and flexible handle 20, this swinging plate passes through
Handle steady pin 50 is fixed in flexible handle 20, and this swinging plate is resisted against on push rod 40, passes through flexible handle
20 drive swinging plate to rotate to promote push rod 40 to slide, the sensitiveest.
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 end is provided with binding clip moving pin 43, and this binding clip moving pin 43 is equipped with in being opened in activity
Binding clip slotted eye 71 on binding clip 70 is interior and can slide in this binding clip slotted eye 71, so, and one side time actually used
Face can prevent movable binding clip 70 stuck, on the one hand also can promote the opening and closing of movable binding clip 70.
Among the present embodiment, described engaging clamp is made up of medical stainless steel material, convenient cleaning and high-temperature sterilization.
Onsite application mode of the present invention is as follows:
The engaging clamp of the present embodiment in use, only need to clutch flexible handle 20, and flexible handle 20 rotates and pushes away
Dynamic push rod 40 forward slip, now elastic component 42 forced compression, during push rod 40 forward slip, binding clip moving pin
43 promotion activity binding clips 70 rotate with binding clip steady pin 61 for axle, and now binding clip moving pin 43 is at binding clip slotted eye
Slide in 71, on the one hand prevent stuck, on the one hand also make movable binding clip close downwards；Unclamp flexible handle 20
After, elastic component 42 pressure disappears, and elastic component 42 resets, and promotes push rod under the effect of elastic component 42
40 slide backward, thus promote flexible handle 20 to reset and movable binding clip 70 opens.
When needs activity binding clip 70 persistently closes with clamping tissue, shifting block 83 is pushed into forward primary importance, this
Time depression bar 81 on carry, the pawl structure of spacer 82 be connected on the axis 813 of depression bar 81 formed engagement,
Pawl structure makes spacer 82 can only continue to slide in groove 812 and cannot slide outward, flexible handle
20 can only continue Guan Bi and cannot open, and movable binding clip 70 also cannot open, thus stings tight tissue block, now
Operator is not required to for a long time firmly grips said handle and can grip out by tissue；When need not clamping tissue, will dial
Block 83 is pushed into the second place backward, and now depression bar is pressed for 81 times, the pawl structure of spacer 82 and axis 813
Being in released state, spacer 82 can in groove 812 slidably, and now flexible handle 20 can freely be opened
Opening and close, movable binding clip 70 also can freely open and Guan Bi, facilitates operation technique.
The above, only present pre-ferred embodiments, therefore the scope that the present invention implements can not be limited according to this,
The equivalence change i.e. made according to the scope of the claims of the present invention and description and modification, all should still belong to the present invention and contain
In the range of.
