Description
Technical field
It is positioned the utility model relates to field of medical article technology more particularly to a kind of clip for artificial blood vessel and solid
Fixed device.
Background technique
For severe aortic vascular lesion or the patient of damage, clinically it is generally necessary to carry out surgery open chest surgery, answer
Manually blood vessel substitutes the blood vessel of itself lesion or damage.Existing artificial blood vessel is that medical macromolecular materials is taken to weave
At tubular structure, in surgical procedure, generally requires and operated in the case where stopping cycling condition, take around 30min, for the arterial blood
There are ischemics, oxygen deficit problem for the organ that pipe dominates, and for ischemic, the more sensitive organ of anoxic, long-time ischemic may shadow
Its function is rung, serious person can lead to organ ischemia, anoxic necrosis.Patent name is artificial blood vessel, Patent No.
A kind of artificial blood vessel is described in the patent of invention of CN201610639554, only needs the operating time of 2min or so can be complete
At operation, but above-mentioned artificial blood vessel is in the course of surgery, and doctor is needed to look for the company of bracket and native blood vessel according to feel
Place is met, then bracket, native blood vessel and clip are fixed with cotton rope, due to feel difference, may cause cotton rope binding loosely
Or binding position is not right, delays operating time or causes the complication such as leakage, bleeding, increases the medical-risk of patient.
Utility model content
To solve in the prior art, artificial blood vessel connects the existing fixed technical problem inconvenient, operation difficulty is big of operation,
The technical solution of the utility model is as follows:
Clip positioning and fixed device of one of the utility model for artificial blood vessel, including clip, pressing hand
Handle, activity orientation arm and bundled piece；The side wall of the pressing handle opens up through slot, and the hoop sleeve is set to the through slot of pressing handle
One end of end, the activity orientation arm is hinged by shaft with pressing handle, and the other end is removably connected with bundled piece；It is described
The distance of bundled piece to shaft is equal to the distance that the clip arrives shaft, when the activity orientation arm rotate to press handle
When axis parallel, the bundled piece is contacted with clip.
Further, the bundled piece is band or cotton rope.
Further, the activity orientation arm is tower structure, and one end far from the pressing handle has notch, described
The end face of notch opens up fixing groove, and the bundled piece is fastened in fixing groove.
Further, annular groove is opened up on the outside of the clip, the annular groove is arranged along the circumferential edge of clip, when
After the bundled piece tightening, the bundled piece is fixed in groove.
Further, two annular stop protrusions are arranged in the outside of the clip, and two annular stop protrusions are along card
The circumferential edge of hoop is arranged in parallel, and after bundled piece tightening, the bundled piece is fixed between two annular stop protrusions.
Clip positioning and fixed device of one of the utility model for artificial blood vessel, compared with prior art,
It has the advantage that:
Clip positioning and fixed device, clip of one of the utility model for artificial blood vessel can pass through handle
Easily release is in bracket and artificial blood vessel junction, and then thumb, index finger press registration arm, fastens band or cotton rope, Ji Keshi
Existing precise positioning and fixation, when can avoid operating in art, doctor with hand with the junction for feeling to find out bracket and artificial blood vessel,
It is easy to use to reduce doctor's operation difficulty, operating time is saved, patients surgery risk is reduced.
Detailed description of the invention
Fig. 1 is a kind of stereoscopic schematic diagram of clip positioning and fixed device for artificial blood vessel in the utility model；
Fig. 2 is a kind of front view of clip positioning and fixed device for artificial blood vessel in the utility model；
Fig. 3 is the top view of Fig. 2；
Fig. 4 is the bottom view of Fig. 2.
Specific embodiment
Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model is clearly and completely described.
Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
Every other embodiment, fall within the protection scope of the utility model.
As shown in Figs 1-4, clip 1 fixed device of one of the utility model for artificial blood vessel, including clip 1,
Press handle 2, activity orientation arm 3 and bundled piece；The side wall of pressing handle 2 opens up through slot 7, and clip 1 is sheathed on pressing handle 2
7 end of through slot, when squeezing pressing handle 2 with hand, the diameter of end becomes smaller, and be detached from clip 1 can easily from end, activity is fixed
One end of position arm 3 and pressing handle 2 are hinged by shaft 5, and the other end is removably connected with bundled piece；Bundled piece is to shaft 5
Distance is equal to the distance that clip 1 arrives shaft 5, when activity orientation arm 3 rotates the axis parallel extremely with pressing handle 2, binding
Part is contacted with clip 1.Bundled piece is band 4 or cotton rope, preferably band 4.
The working principle of the utility model is as follows:
In vitro under cycling condition, the lesion vessels of patient are cut, clip 1 is first mounted on to the end of pressing handle 2, are pricked
Band 4 is mounted on activity orientation arm 3, and activity orientation arm 3 lifts, and the end for pressing handle 2 is protruded into the cut ends of patient vessel,
So that clip 1 is connected to the inner wall of blood vessel, rotation activity orientation arm 3 to 1 direction of clip, at this time activity orientation arm 3 just with clip 1
Position it is corresponding, tense band 4 be allowed to pre-fix clip 1 and patient's native blood vessel, squeeze press handle 2 make the straight of its end
Diameter becomes smaller, and clip 1 is detached from from the end of pressing handle 2, pressing handle 2 is exited, by conveying device by integral type artificial blood vessel
Holder part reach in clip 1, discharge, be fixed on clip 1 between bracket and native blood vessel, finally tense band 4
It realizes and fixes.
Activity orientation arm 3 is tower structure, and one end far from pressing handle 2 has notch, and the end face of notch opens up solid
Determine slot 6, bundled piece is fastened in fixing groove 6.
To prevent bundled piece from sliding from clip 1, in one embodiment, the outside of clip 1 opens up annular groove 8,
Annular groove 8 is arranged along the circumferential edge of clip 1, and after bundled piece tightening, bundled piece is fixed in annular groove 8.
In another embodiment, two annular stop protrusions, two annular stop protrusion edges are arranged in the outside of clip 1
The circumferential edge of clip 1 be arranged in parallel, after bundled piece tightening, bundled piece is fixed between two annular stops protrusions.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with the power
Subject to the protection scope that benefit requires.
