Abstract
This utility model relates to a kind of Endo-GIA of convenient clamping, the movable shank of the key comprising nail supporting base, assembly clamping plate and be arranged on assembly clamping plate, and described movable shank of the key and assembly clamping plate are formed and are rotatably assorted; Movable shank of the key is provided with release-push, be slidably connected between described release-push and movable shank of the key, between the front end of described release-push and movable shank of the key, back-moving spring is set, resilient engagement is formed between described release-push and movable shank of the key, the tail end of described assembly clamping plate is provided with hook, described release-push is provided with the hook groove for matching with this hook.While movable shank of the key pins alignment pin, the hook on clamping plate tangles the release-push on shank of the key through hook groove, thus movable shank of the key is not easily got loose, and can prevent it from being flicked.
Description
Technical field
This utility model relates to a kind of Endo-GIA of convenient clamping.
Background technology
Traditional Endo-GIA as shown in Figure 1, comprise nail supporting base (10), nail supporting base cover plate (20), to ailhead, assembly clamping plate (30), movable shank of the key (40) etc.
When Endo-GIA uses, pin alignment pin by movable shank of the key (40) and realize docking of nail supporting base (10) and assembly clamping plate (30), grip tissue is to carry out related surgical operation then.Movable shank of the key (40) is lifted to discharge alignment pin to be separated upper and lower parts after finishing using.Strength appropriateness when current structural requirement apparatus is locked, too be tightly inconvenient to operate, too loose apparatus is subject to external force and has the risk flicked, and control has certain difficulty.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of Endo-GIA of convenient clamping.
This utility model solves the technical scheme that its technical problem adopts: a kind of Endo-GIA of convenient clamping, the movable shank of the key comprising nail supporting base, assembly clamping plate and be arranged on assembly clamping plate, and described movable shank of the key and assembly clamping plate are formed and are rotatably assorted;
Described movable shank of the key is provided with release-push, be slidably connected between described release-push and movable shank of the key, between the front end of described release-push and movable shank of the key, back-moving spring is set, resilient engagement is formed between described release-push and movable shank of the key, the tail end of described assembly clamping plate is provided with hook, described release-push is provided with the hook groove for matching with this hook.
Further, the below of described movable shank of the key is provided with the spring leaf for resetting.
Further, the tail end of described release-push forms thumb press curved surface.
The beneficial effects of the utility model are: when movable shank of the key pins alignment pin while, the hook on clamping plate tangles the release-push on shank of the key through hook groove, thus movable shank of the key is not easily got loose, and can prevent it from being flicked.
Release-push releasing activity shank of the key can be pressed when the procedure is completed and movable shank of the key restPoses under the effect of spring leaf, thus make more convenient to operate.

Detailed description of the invention
By reference to the accompanying drawings this utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with this utility model.
As shown in Fig. 2 to 8, a kind of Endo-GIA of convenient clamping, the movable shank of the key 2 comprising nail supporting base, assembly clamping plate 1 and be arranged on assembly clamping plate 1, movable shank of the key 2 is formed with assembly clamping plate 1 and is rotatably assorted.
Movable shank of the key 2 is provided with release-push 3, be slidably connected between release-push 3 and movable shank of the key 2, between the front end of release-push 3 and movable shank of the key 2, back-moving spring 4 is set, resilient engagement is formed between release-push 3 and movable shank of the key 2, the tail end of assembly clamping plate 1 is provided with hook 6, release-push 3 is provided with the hook groove 32 for matching with this hook 6.
The below of movable shank of the key 2 is provided with the spring leaf 5 for resetting.The tail end of release-push 3 forms thumb press curved surface 31.
As shown in Figure 5, before percussion, press down rotation activity shank of the key 2, hook 6 touching release-push 3, makes release-push 3 forward stressed, mobile also compression reseting spring 4; As shown in Figure 6, after hook 6 enters completely, under the effect of back-moving spring 4, release-push 3 recovers, and hook 6 coordinates with the hook groove 32 on release-push 3, thus movable shank of the key 2 is not easily unclamped, and now anastomat just can complete percussion task; As shown in Figure 7, after percussion task completes, through thumb press curved surface 31, press release-push 3 forward, hook 6 is now in free state; Then, as shown in Figure 8, under the effect of spring leaf 5, after movable shank of the key 2 throws off assembly clamping plate 1, original state is returned to.
Adopt Endo-GIA of the present utility model, after movable shank of the key 2 coordinates with assembly clamping plate 1, movable shank of the key 2 can be made not easily to get loose, can prevent it from being flicked.Release-push 3 releasing activity shank of the key 2 can be pressed when the procedure is completed and movable shank of the key 2 restPoses under the effect of spring leaf 5, thus make more convenient to operate.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content in description, must determine its technical scope according to right.
