Description
Technical field
The utility model relates to the field of medical instrument technology, and in particular to a kind of netraneurysm folder.
Background technique
Clinically, intracranial aneurysm, which carries out classification by form, can be divided into hepatic hydatid disease, netraneurysm, dissecting aneurysm
With irregular aneurysm.The most common are the hepatic hydatid disease for having the base of a fruit, most common treating method be exactly mechanicalness filling and it is general
Logical artery clamp folder closes.It is extremely low wider but for netraneurysm, it can not press from both sides and close from root；Simultaneously without capsule structure, it is also difficult into
Row filling.Currently used method is to be clamped by aneurysm clip to the blood vessel at tumour place, and aneurysm is pushed back blood
In pipe, prevent from threatening to circumvascular nerve after aneurysm is prominent.Aneurysm clip includes handle, elastic mechanism and two
Grip block；Since blood vessel weave in forms rete vasculosum, the longer handle of aneurysm clip can be to other blood vessels or mind of surrounding
Through interfering；Meanwhile after elastic mechanism failure, two grip blocks can open, and aneurysm can be protruded again, again to trouble
Person's life threatens.
Utility model content
The purpose of this utility model is to provide a kind of to will not influence it after clamping with the blood vessel of netraneurysm
His blood vessel or nerve, while self-locking netraneurysm folder is able to achieve after elastic mechanism failure.
In order to achieve the above objectives, the technical solution of the utility model is to provide a kind of netraneurysm folder, including torsional spring and
Two clamping units being oppositely arranged, each clamping unit include the grip shank of arc folder and arc, and the arc folder includes interior
Double wall and outer double wall；Described grip shank one end is fixedly connected with arc folder, and the grip shank other end is contacted with outer double wall, described
Biological membranous layer is coated on interior double wall；The torsional spring both ends are fixedly connected with two grip shanks respectively, in the middle part of the torsional spring with two
Grip shank contact, two grip shanks are articulated with the position between the torsional spring and arc folder.
The technical principle of this programme is: torsional spring is pulled, torsional spring drives grip shank rotation, so that two arc folders are opened,
Two arcs are clipped on blood vessel after opening, then torsional spring resets, and closes two arc clips, so that the shuttle shape of protrusion be moved
Arteries and veins tumor pushes back intravascular.
This programme has the technical effect that after torsional spring failure, since two grip shanks are hinged, hinge joint and torsional spring cooperate shape
At self-locking, two arcs folders will not open, and aneurysm will not be protruded again, to release aneurysm protrusion to the life of patient
It threatens；Simultaneously grip shank contact with outer double wall so that two arcs press from both sides and two grip shanks combine after it is oval, moved with tradition
The relatively long handle of arteries and veins tumor folder is compared, and this programme will not interfere other blood vessels or nerve after clamping blood vessel, and fail in torsional spring
Grip shank can externally double wall play a supportive role afterwards.
Further, the grip shank is equipped with the holding tank with cooperation in the middle part of torsional spring.Having the technical effect that for this programme will
Torsional spring is placed in the stability that torsional spring can be improved in holding tank, while lock is realized in torsional spring and the cooperation of the hinge joint of two grip shanks
It is not easy to slide when tight effect, so that it is guaranteed that the clamping effect of arc folder.
It further, further include tension spring, tension spring both ends are fixedly connected with two grip shanks respectively.The technical effect of this programme
Be: after torsional spring failure in the case where hinge joint and torsional spring cooperatively form self-locking, arc folder is can be improved in the pulling force of tension spring
Fastening degree, effectively prevent aneurysm to protrude.
Further, medical adhesive dressing oxidant layer is equipped on the face that two arc folders contact with each other.The technical effect of this programme
It is: can also be effectively sterilized while preventing arc folder from opening.
Further, the arc folder and grip shank are integrally formed.This programme has the technical effect that on the one hand convenient add
On the other hand work ensures that junction is more smooth, will not scrape injured tissue.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of netraneurysm folder of the utility model；
Fig. 2 is enlarged drawing at A in Fig. 1.
Specific embodiment
Below by the further details of explanation of specific embodiment:
Appended drawing reference in Figure of description include: torsional spring 1, the first arc press from both sides the 2, first grip shank 3, first in double wall 4,
First outer double wall 5, the second arc press from both sides double wall 8, the second outer double wall 9, holding tank 10, tension spring 11 in the 6, second grip shank 7, second.
A kind of netraneurysm folder as shown in Figure 1, including torsional spring 1, positioned at first clamping unit in left side and positioned at the right side
Second clamping unit of side, the ellipsoidal cross section of aneurysm clip.First clamping unit includes the first arc folder 2 and the first clamping
Handle 3, the first arc folder 2 include double wall 4 and the first outer double wall 5 in first；2 one of first grip shank, 3 right end and the first arc folder
Molding, 3 left end of the first grip shank is contacted with the first outer double wall 5.
Second clamping unit includes the second arc folder 6 and the second grip shank 7, and the second arc folder 6 includes 8 He of double wall in second
