Abstract
The utility model discloses a limiting structure of an anorectum anastomat. The limiting structure comprises a push rod and a needle bin sleeve. The push rod is connected with the needle bin sleeve through a bushing, the bushing is installed in a fixed handle, one end of the bushing is connected with the needle bin sleeve, the other end of the bushing is in coaxially assembled connection with the push rod, the push rod is provided with a limiting boss, and an inner wall of the bushing is provided with a limiting block corresponding to the limiting boss. The rear end of the bushing is made into the limiting structure, force is transmitted to the fixed handle through the bushing, large force can be borne, a clamping opening structure is omitted, and instrument safety is improved.
Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of position limiting structure of anorectal anastomat.
Background technology
The anorectal anastomat now is widely used in the hemorrhoid operation.Present product and its initial product are no matter be that bigger variation has all taken place for profile or internal structure.Topmost variation is that original nail bin cover adopts tightening ring to be connected with the aluminum straight tube, now its merging has been become monoblock type nail bin cover.
Monoblock type nail bin cover adopts bayonet coupling with the device body by lining, spacing after present apparatus adopts nail bin cover rear end as percussion.Handle a period of time compressing tissue owing to continue firmly to hold with a firm grip after operation needs to pull the trigger, nail bin overlaps spacing need and bears more energetically, and the junction bayonet socket is deviate from easily.
The utility model content
The technical problem that this utility model mainly solves provides a kind of position limiting structure of anorectal anastomat, can avoid bayonet arrangement, has improved the safety of apparatus.
For solving the problems of the technologies described above, the technical scheme that this utility model adopts is: the position limiting structure that a kind of anorectal anastomat is provided, comprise: push rod and needle chamber cover, be connected by a lining between described push rod and the needle chamber cover, described lining is installed in the fixed handle, and described lining one end is connected with described needle chamber cover, and the other end is connected with the coaxial assembling of push rod, described push rod is provided with positive stop lug boss, and the described lining inwall of corresponding described positive stop lug boss is provided with limited block.
In preferred embodiment of this utility model, described lining is provided with buckle, by bayonet socket and the clamping of needle chamber cover.
In preferred embodiment of this utility model, described push rod is straight push rod.
In preferred embodiment of this utility model, described positive stop lug boss is semicircle positive stop lug boss.
In preferred embodiment of this utility model, described limited block is semicircle limited block.
The beneficial effects of the utility model are: the position limiting structure of this utility model anorectal anastomat adopts the lining rear end to make position limiting structure, and power is delivered to fixed handle by lining, can bear more energetically, has avoided bayonet arrangement, has improved the safety of apparatus.
Description of drawings
Fig. 1 is the structural representation of position limiting structure one preferred embodiment of this utility model anorectal anastomat;
Fig. 2 is the explosive view of the position limiting structure of anorectal anastomat shown in Figure 1;
The labelling of each parts is as follows in the accompanying drawing: 1, push rod, 2, positive stop lug boss, 3, limited block, 4, lining, 5, the needle chamber cover, 6, fixed handle, 7, bayonet socket.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1 and Fig. 2, this utility model embodiment comprises:
A kind of position limiting structure of anorectal anastomat comprises: push rod 1 and needle chamber cover 5, described push rod 1 be connected by a lining 4 between needle chamber overlaps 5, described lining 4 is installed in the groove of a fixed handle 6 correspondences.Push rod 1 described in the utility model is preferably straight push rod.
Described lining 4 one ends are connected with described needle chamber cover 5, and described lining 4 is provided with buckle, overlaps 5 clampings by bayonet socket 7 and needle chamber.
Lining 4 other ends connect in push rod 1 coaxial assembling, and described push rod 1 is provided with positive stop lug boss 2, and corresponding described positive stop lug boss 2 described lining 4 inwalls are provided with limited block 3.
The preferred described positive stop lug boss 2 of this utility model is semicircle positive stop lug boss.Described limited block 3 is semicircle limited block 3.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes this utility model description and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
