Description
Technical field
The present invention relates to medical instruments fields, and in particular to a kind of blood vessel anastomat.
Background technology
Vascular anastomosis technology starts from Carrel before more than 100 years, and A, (1908) and Hopfnet, E, (1903) etc. apply hand
Work sewing carries out vasotransplantation and the replantation of a severed limb, and by the development of more than 100 years, this technology has been widely used for respectively
In kind surgical operation.At present, the anastomosis of five major classes have been developed in vascular anastomosis.
First, blood vessel suture anastomosis
Using suture carry out vascular anastomosis be currently generally acknowledged vascular anastomosis standard method and a few days ago clinically most often
Vascular anastomosis method.With the development of medicine, more and more operations use this mode.The scope of application has been directed to shaping
The various fields such as surgery, liver and gall surgical department, cardiothoracic surgery, Urology Surgery, gynemetrics.But suture method anastomosis of blood vessel also has shortcoming：
1) cumbersome, operating time is very long；2) it is higher to the skill set requirements of doctor, it is difficult expertly to slap in a short time without training
It holds；3) surgical quality is easily influenced by the psychology of doctor, physiology fluctuation；4) blood vessel is elastic, soft, scalable tissue,
Manual suture is difficult that it is positioned, and suture needle is difficult accurately to suture.So carrying out vascular anastomosis using suture, it is easy to appear sutures
Not close, suture is too deep or excessively shallow, sutures the problems such as too tight or too loose, causes blood vessel leakage or vascular thrombosis symptom, finally causes
The failure of operation.
2nd, blood vessel mechanicalness anastomosis
It is with a kind of vascular anastomosis of special vascular anastomosis device replacement or partial alternative suture that blood vessel mechanicalness, which is coincide,
Method can be divided into tiretube process, needle ring method etc. according to principle.The application of mechanical vascular anastomosis significantly simplifies operation behaviour
Make, shorten operating time, reduce tissue damage and postoperative infection chance in art.But also there is distinct disadvantage：1) because to make
Blood vessel is connected with set or ring, so anastomosis blood vessel is stiff, blood vessel normal contraction and the physiological function of diastole is affected, and limits
The growth of blood vessel has been made, therefore has been not suitable for teenage patient；2) blood vessel of pullling of relatively large distance is needed when coincideing, easily causes blood vessel
Tear；3) cannot coincide the discrepant blood vessel of caliber.4) easily foreign body granuloma is formed in externa.
3rd, blood vessel bonds anastomosis
It is a kind of side that the blood vessel both ends of close apposition are glued together using medical adhesive that blood vessel, which bonds anastomosis,
Method.Before bonding, it is necessary to be smeared again after blood vessel close apposition, avoid adhesive intravasation chamber.Bond anastomosis
Major advantage damages the transmural at vascular anastomosis in avoiding suture needle and suture, eliminates the foreign matters such as suture to tube wall
Long stimulus caused by productive reaction.Its shortcoming is also very apparent：1) bond after previous anastomotic poor flexibility, matter is crisp, has
Certain toxicity；2) first suture needle traction blood vessel or built-in hollow stent are needed, because blood vessel is a hollow hose, row bonds
It need to show when identical and blood vessel both ends are maintained into open state；3) if can reach adhesive does not enter tube chamber, operating difficulty is very big,
It is high to the operation level requirement of doctor.
4th, blood vessel laser anastomosis
The mechanism of laser anastomosis of blood vessel is that luminous energy is changed into thermal energy, raises local tissue temperature, fibrinolysis,
Polymerization, solidification, so that ends of vessels is bonded together.The advantages of laser coincide：1) weld tissue inflammation reaction is small, is formed
Adhesion and narrow phenomenon are small, and organization healing is fast；2) blood vessel after coincideing can be grown with individual growth, suitable for the children growth phase
Blood vessel coincide.The shortcomings that laser coincide：1) the vascular anastomosis initial stage compressive resistance that laser coincide is relatively low, this is also laser kiss
Conjunction technology is in the bottleneck of clinical practice；2) blood vessel holder is needed, in order not to be polluted to blood, so to vessel support
The requirement of object is very high.At present, the method for finding the initial compressive resistance that can improve engaging tissue is such modus operandi research
Direction.If future can have breakthrough, blood vessel laser, which coincide, can just be gradually available for clinic.
5th, blood vessel high-frequency electrocoagulation anastomosis
Blood vessel high-frequency electrocoagulation anastomosis are the methods for completing vascular anastomosis using electric heating solidification.By the way that high-frequency electrical is circulated
Become thermal energy, make the protein receptor thermocoagulation in externa and middle level, so as to achieve the purpose that anastomosis of blood vessel.Heat suitable for when,
The tissue of this solidification can keep the continuity of blood vessel, and can retain tissue biological and learn characteristic.If otherwise electric current is excessive, continue
Overlong time, bonding place make bonding insecure by comprising excessive solidified structure；And it is difficult to bond during shortage of heat.Meanwhile
Coagulation tweezers are easy to cling tissue, and previous anastomotic is often easily torn when removing tweezers.Therefore, the size and kiss of electric current are strictly grasped
It is the key that such method success to close the time.
At present, it is needle ring method that mechanical vascular anastomosis are most commonly used in clinic.Using 2 small rings of plastics, every
6 small pins and 6 apertures are uniformly alternate on small ring, and through aperture, turning up and is fixed on 6 by 90 degree for one side ends of vessels when coincideing
On small pin；Other end blood vessel equally operates, then the pin of two needle rings, hole are mutually embedded in pairing.Its shortcoming includes：1) compared with blood
For pipe diameter, the length of small pin is very long, before coincideing, it is necessary to the length that vascular wall stretches higher than needle point, and turns up 90 degree and consolidates
Due on pin, since stretching is long, easily cause the tear of blood vessel；2) internal diameter of two plastic hoops necessarily requires unanimously, so
Cannot coincide the discrepant blood vessel of caliber；3) after coincideing, plastic hoop is permanently sleeved on vessel outer wall, can not only generate body
Rejection, and blood vessel can be caused stiff, and blood vessel normal contraction and the physiological function of diastole are affected, limit blood vessel
Growth.
The present invention inherit the existing machinery anastomosis operation time it is short, be easy to standardization the advantages that on the basis of, further change
The shortcomings that being apt to above-mentioned needle ring method.
