Description
Technical field
The utility model be related to surgical operating instrument, particularly cranial surgery be used for press from both sides close the fixture of arteries tumour.
Background technology
Aneurysm clip in operation for intracranial aneurysm using widely, its product and species and model on the market at present
It is various.Because the position of intracranial aneurysm generation is different and comes in every shape, therefore, if the operation of every entocranial artery needs to prepare
The aneurysm clip of dry type number is very more, is closed for selecting suitable aneurysm clip to carry out folder.Operation is set to become complicated, it is difficult to grasp
Make.In addition the surgical field of view narrow space, no small difficulty is added to clip operation.
Chinese patent literature is disclosed a kind of " aneurysm clip and the aneurysm clip placement pliers coordinated with it "
(CN201120337070.8).Two jig arm that the aneurysm clip is combined together by elastomeric element, the jig arm includes using
Provided with recessed on the outside of the gripping section and the lever piece of control gripping section activity of clamping Aneurysmal neck, the lever piece of two jig arm
Groove, the groove is corresponding with the lever piece bearing of trend of jig arm;There is problems with it:The gripping section of its jig arm can not be to multiple
Miscellaneous shape, such as arc, the aneurysm of semicircle shape carry out effective totally enclosed type folder and closed, thus this complicated shape is moved
Arteries and veins knurl, can only carry out folder using multiple clips and close, increase operating difficulty, and to close effect undesirable for folder.
Chinese patent literature is also disclosed " a kind of articulated type aneurysm clip "(CN201610254105.9).Pass through elasticity dress
Put and connect as one and two retractable jig arm, fair device is connected between two jig arm, two jig arm are included extremely respectively
It is hinged between few two joint arms, adjacent two joint arm using hinge ... ....Its whole jig arm can be with curved or semicircle
Type ... ..., so that adapting to the especially many side encirclement type aneurysms ... ... of different shape realizes complete clamping aneurysm.
But, there is following defect in it:First, parts are more, structure is more complicated;Second, due to the visual area scope very little of operation of opening cranium,
Especially in the case of one perforate of head, aneurysm is located at arteries behind, and the aneurysm clip can not be across blood vessel to aneurysm
Folder is carried out to close.
Utility model content
The purpose of this utility model, which is to provide one kind, to be closed across blood vessel to the vertical folder of irregular aneurysm progress(Along parallel to
Artery direction folder is closed)Roll in stretch formula aneurysm clip.
What the purpose of this utility model was realized in:One kind stretches formula aneurysm clip, left jig arm and right jig arm shape in can rolling over
Shape is symmetrical, and left and right jig arm is linked together by spring, and two blend stops are separately positioned on the friendship on the forward and backward surface of left and right jig arm
Near mutual position, the left jig arm is hinged by lever piece and gripping section to be constituted, and gripping section is sequentially cut with scissors by more than one articular lamella
Connect and form, lever piece is made up of left convex semicircle segmental arc and right convex section and left ramp down section tandem array.
The articular lamella is that the axle on three, previous articular lamella is loosely inserted into the hole on lever piece top, latter joint
Axle on plate is loosely inserted into the hole on previous articular lamella, and three articular lamellas be hinged after the clamping face that is formed be a plane.
The lower inside of the lever piece has for strutting the flange that support is engaged.
Another object of the present utility model, which is to provide one kind, to be closed across blood vessel to the horizontal folder of irregular aneurysm progress(Hang down on edge
It is straight to be closed in artery direction folder)Roll in stretch formula aneurysm clip.
What the another object of utility model was realized in:One kind stretches formula aneurysm clip, left jig arm and right jig arm in can rolling over
Symmetrical shape, and left and right jig arm is linked together by spring, two blend stops are separately positioned on the forward and backward surface of left and right jig arm
Near interaction locations, the left jig arm is hinged by lever piece and gripping section to be constituted:Lever piece is by left convex semicircle segmental arc and right convex arc
Shape section and left ramp down section tandem array composition, activity insertion is horizontal respectively for two piece axles of the gripping section on two vertical articular lamellas
Constituted into two holes at the left and right two ends of articular lamella, and in the hole in the middle part of the horizontal articular lamella of axle activity insertion on lever piece.
The clamping face that the horizontal articular lamella and two vertical articular lamellas are formed after being hinged is a plane.
The lower inside of the lever piece has for strutting the flange that support is engaged.
Compared with prior art, the beneficial effects of the utility model are:
1st, parts are few, simple in construction, are easy to processing.
2nd, the alternative existing multiple aneurysm clips of this aneurysm clip one, and complete to close irregular aneurysmal folder, and
Folder can be carried out across arteries to the aneurysm behind the blood vessel of visual area to close.
To complicated shape(Irregularly, it is curved etc.)Aneurysm clip closed operation, it is not necessary to multiple aneurysm clips, only need one
This individual aneurysm clip can be completed.After the exposure of visual area, using gripper clamp clipping operation section(Also referred to as handle)The flange of bottom, overcomes
The elastic force of spring, left and right jig arm is parallel separated, the gripping section of left and right jig arm is directed at aneurysmal root, and according to artery
The profile of knurl, the articular lamella of bending gripping section carries out folder and closed.
Irregular aneurysm of this aneurysm clip before to visual area direction arteries carry out folder close it is outer, moreover it is possible to across moving
Arteries and veins blood vessel carries out folder to the aneurysm after blood vessel and closed.
This money aneurysm clip is that turning joint plate and two lever piece shapes are devised on the basis of existing aneurysm clip
Into for crossing over arterial vascular circle, the shape that aneurysm clip can be constantly adjusted by the activity in joint closes different shape to press from both sides,
The aneurysm of diverse location.Folder closes local blood vessel structure can be fully reduced after aneurysm, form, out of shape, will not cause part
Narrow, the distortion of blood vessel.Make blood vessel patency more preferably, the compliance of blood flow is bigger, and the spasm extent of blood vessel is lighter.Reduce
The incidence of cerebral ischemia and cerebral infarction.Therefore, the advantage of this aneurysm clip allows operation for intracranial aneurysm more human nature and more
Safety.
