Sawtooth is provided with sliding-rail groove 31, is meshed, sliding ball 34 can be entered using the pointed tooth 344 of sawtooth and tooth element
Row control, it is ensured that when need not slide；But in 1 stress of connecting rod, connecting rod 1 is driven by head lifting part 33 and slided
Dynamic ball 34 is moved, and so because the sawtooth in sliding-rail groove 31 produces pressure to the pointed tooth 344 of tooth element, can make to support with pointed tooth
The spring 343 that body 345 is connected is compressed so that sliding ball 34 can be slided in sliding-rail groove 31 again；It so can both meet connection
The movement of bar 1, when to vascular suture, can limit the movement of connecting rod, it is to avoid vascular suture process is impacted again.
Preferably, as shown in figure 4, length direction of the guide pin slot 21 along the assistor 2 is set.During vascular anastomosis,
The blood vessel two ends for needing vascular anastomosis are respectively fitted over to the two ends of assistor 2, at this moment, the horizontal guide pin slot 21 on the surface of assistor 2
Vertical with vascular anastomosis, the direction of guide pin slot 21 is the direction of routing of suture needle.During vascular anastomosis, suture needle is according to guide pin slot 21
Direction carry out vascular anastomosis, it is to avoid the problem of vascular anastomosis for looking for inaccurate direction to cause deviates, be also avoided to find direction accurately
Time-consuming problem.
Preferably, above-mentioned assistor 2 is elliptical cylinder body.Because vessel sections are circle, assistor 2 is set to ellipse
The position that blood vessel is preferably needed vascular anastomosis by circular cylinder physical efficiency is propped up, convenient operation；Other elliptical cylinder body is propped up
The one side of vascular anastomosis is needed, and some spaces are also left apart from the back side of blood vessel, the one side of vascular anastomosis had so both been propped up,
Blood vessel will not again be propped up excessive, so as to cause angiorrhoxis.
Preferably, above-mentioned guide pin slot 21 can set several on assistor 2, during vascular anastomosis, be kissed when needing blood vessel
After the position of conjunction is sewed it up, by adjusting the direction of connecting rod assistor 2 can be made to rotate in the blood vessel, make next guide pin slot 21
The position of vascular anastomosis the need for being in newly, then continues to suture, up to needing suture using suture needle in new guide pin slot 21
Position sew it up untill.Several guide pin slots 21 are set, facilitate vascular anastomosis, it is to avoid the operation that only one of which guide pin slot 21 is caused
Complicated the problem of.
Preferably, guide pin slot 21 should have certain depth, and this depth should be adapted to passing through for suture needle.Vascular anastomosis
When, direction cabling of the suture needle along guide pin slot 21 penetrates blood vessel and when pass blood vessel, it is necessary to certain space in suture needle,
When passing blood vessel, because exterior space is big, so will not be impacted to suture needle, if but the depth of guide pin slot 21 not enough,
Suture needle cannot be made easily to pass in and out blood vessel, vascular suture is impacted.So, guide pin slot 21 is provided with certain depth,
It can be suture needle intravasation slot milling, facilitate the progress of vascular anastomosis.

Into.The connecting rod movable part 11 can be made up of metals such as the less filamentary silvers of diameter, and other regions of connecting rod 1 can be by being relatively large in diameter
The material such as filamentary silver, stainless steel or hard medical plastic be made.Because connecting rod movable part 11 can be bent, vascular anastomosis it
Before, connecting rod movable part 11 is first adjusted into correct position, connecting rod 1 is formed suitably with assistor 2 during so as to vascular anastomosis
Angle, facilitates the progress of vascular anastomosis.
Preferably, the one end of above-mentioned connecting rod 1 away from the assistor 2 is provided with handle 4.The handle 4 can be by nontoxic wood
Material or plastics are made, and material therefor needs to adapt to hot environment, to be gone out to the vascular anastomosis support with guide pin slot
Bacterium sterilizes.Handle 4 is arranged at the one end of connecting rod 1 away from assistor 2, and medical personnel use the vascular anastomosis support with guide pin slot
When, can be with hand-held handle 4 at, use vascular anastomosis support with guide pin slot more convenient.
Preferably, the assistor 2 of the above-mentioned vascular anastomosis support with guide pin slot should be designed so that several model, such as ellipse
The real axis of round cylinder and the length of the imaginary axis can be arranged to different ratios, to adapt to the blood vessel of different tube diameters, use
Before should according to it is required suture blood vessel caliber carry out selection use.Medical personnel choose suitable before vascular anastomosis is carried out
The vascular anastomosis support with guide pin slot, to adapt to the blood vessel of different tube diameters, the process of vascular anastomosis can be accelerated, also made identical
Process is more convenient.
Preferably, above-mentioned slide rail connector 3 should be arranged to sufficiently small part, on assistor 2, connect assistor
2 with connecting rod 1.When carrying out vascular anastomosis, the size of whole assistor 2 intravascular due to the two ends of assistor 2 being put into
It is unsuitable excessive, and slide rail connector 3 is connected on assistor 2, as a part for assistor 2, if slide rail connector 3 is excessive,
The oversized of whole assistor 2 can be caused, it is impossible to and blood vessels caliber matches.So, by slide rail connector 3 set enough to
It is small, be conducive to the size by assistor 2 to diminish, medical personnel also can more easily use band guide pin when carrying out vascular anastomosis
The vascular anastomosis support of groove.
Preferably, the surrounding of assistor 2 and surface should be set to smooth structure, during operation, and the smooth structure, which can reduce, to rub
Wipe power, make assistor 2 be placed into it is intravascular and when rotating in the blood vessels, can be more smooth, it is unobstructed, it also avoid pair
The abrasion of vascular wall, plays a part of protecting blood vessel.
