The scalable take-up 8 provides 0.5 to 2 N of traction force.
The folding device 12 realizes folder function by internal torsion spring.
In use, Circular permanent magnet iron 6 is anchored on extension plate 10 by magnetic force, by adjusting anchoring height, so as to change
Become drawing angle.
It can make have 0-270 degree angle between substrate plate 11 and extension plate 10 by adjusting the folding device 12.
The basin body 14 has upper edge, and square shaped pin hole 2 15 has several, is distributed in the upper edge.
Compared with prior art, the beneficial effects of the present invention are:
It can be single by three traditional people's operational transitions 1. the scalable blood vessel clip of magnetic orientation can replace manually pulling in art completely
People's operation, is greatly saved manpower；
2. the substrate plate of foldable extension plate is fixed on by bolt repairs liver basin lateral edge, extension plate is scalable as magnetic orientation
The positioning site of blood vessel clip can pull the angle of angle adjustment extension plate and substrate plate, adjustable range 0 according to needed for patient
Degree is to 270 degree；
3. the scalable blood vessel clip of magnetic orientation is located on extension plate by magnet, angle can be pulled according to needed for patient by magnetic
Sprocket bit point is finely adjusted, and in addition can be pulled dynamics by changing line stretcher length adjustment, will not be damaged group in drawing dynamics
Under the premise of knitting, makes drawing that can sufficiently expose surgical field of view, provide tension for surgical procedure.

Specific embodiment
The embodiment that the present invention will be described in detail with reference to the accompanying drawings and examples.
Magnetic orientation instrument is the important directions of magnetic surgery research, can pass through the directly or indirectly side of contact using magnetic material
Formula generates the characteristic of power effect, realizes the space orientation of functional module.The advantage of magnetic orientation instrument is pointing device design letter
It is single, it is not required to occupy too large space, while being easy to convert position location, move functional module can flexibly in working space.This
Before, in terms of the research of magnetic orientation instrument has been focused into laparoscopic instrument, it is intended to reduce abdominal cavity by magnetic orientation laparoscopic instrument
The quantity or diameter of mirror stamp card, improve operation minimal invasive.Therefore, designing a kind of small and exquisite, crawl precision can be appointed by repairing liver patient
The magnetic orientation instrument of meaning adjustment, for pulling, fixing liver and liver surrounding tissue, it is possible to reduce greatly improved while manpower
Repair hepatic efficiency.
Based on above-mentioned thought, overall structure of the invention as shown in Figure 1, by the scalable blood vessel clip 1 of two to four magnetic orientations,
Two to four foldable extension plates 2, one is repaired the composition of liver basin 3.
The scalable blood vessel clip 1 of magnetic orientation is as shown in Fig. 2, by Circular permanent magnet iron 6, nylon wire 7,8 and of scalable take-up
Blood vessel clip 9 four basic original part compositions, each scalable blood vessel clip altitude simulation manpower of magnetic orientation can be according to traction needed for operation
Power size adjusts the flexible line length of nylon, and traction force is controlled at 0.5 to 2 N, can guarantee not injury tissue and provides enough lead
Drawing tension；It can change drawing angle simultaneously by adjusting position of the magnet on extension plate 10.
For foldable extension plate 2 as shown in figure 3, being made of extension plate 10 and substrate plate 11, two pieces of stainless steel plates pass through folding
Device 12 connects.Extension plate 10 is that the magnet 6 of the scalable blood vessel clip 1 of magnetic orientation provides positioning site.The control of magnetic orientation binding force
It at 5 Ns or so, can guarantee in repairing liver operating process, magnetic orientation will not fall off easily, and patient can be according to drawing angle demand
Arbitrarily adjustment position location.The effect of substrate plate 11 is to be fixed on extension plate 10 to repair in liver basin lateral edge 14, central square pin
Hole 13 with repair the square shaped pin hole 15 of same size in liver basin lateral edge 14 through bolt 4 it is fixed can guarantee it is fixed, substrate plate in
Repair the swing offset that will not issue licence between liver basin.In addition, there is 0-270 degree angle between substrate plate 11 and extension plate 10, which can
It is adjusted by folding device 12, so as to provide more angle Selections for drawing.
The structure of liver basin 3 is repaired in the present invention as shown in figure 4, main material is carrying magnetic stainless steel, structure is band lateral edge 14
Basin body, repairing liver surgery can carry out in the basin.15 function of square shaped pin hole in lateral edge 4 is as described above.
Use process of the invention such as Fig. 5, liver 5 is placed in basin during repairing liver, is utilized respectively two scalable blood vessels
The fixed liver superior and inferior vena cava 16 of blood vessel clip 9 and infrahepatic vena cava 17 on folder 1, tensile nylon line 7, by 6 anchor of Circular permanent magnet iron
Be scheduled on extension plate 10, adjust anchoring height on extension plate 10 to adjust drawing angle, adjust 7 tensile elongation of nylon wire with
Traction force is adjusted, to keep liver superior and inferior vena cava 16 and 17 holding of infrahepatic vena cava horizontal, there is tension, convenient for finishing.
