Abstract
The invention discloses a magnetic device applicable to anastomosis of large vessels. Two elliptic-cylinder-shaped anastomosing rings which correspond to the pipe diameter of the large vessels to be anastomosed and contain permanent magnets are utilized to finish anastomosis of the vessels with different pipe diameters; the opposite surfaces of two permanent magnet anastomosing rings are smooth and polished, so that the endangiums of the vessels are neatly aligned, and further the defects of narrow anastomosing ports, blood leakage, and various complications such as massive haemorrhage, local tissue granuloma and pseudoartery formation and the like due to slipping of ligatures caused by manual suture for anastomosis are avoided; as the anastomosing rings are designed to be elliptic-cylinder-shaped, clamping and fixing with surgical instruments in surgery are convenient, and the magnetic device is very beneficial to anastomosis operation of the large vessels at deep parts of the body cavity; and the time of utilizing the anastomat to carry out anastomosis on the large vessels is more than five times shorter than that of manual anastomosis, so that the condition that the blood of tissues and organs are blocked for long time so as to cause ischemic operation of the organs or congestion and edema and further cause dysfunction of the organs. In addition, the end surface adopts conical titanium alloy needles and corresponding conical small holes so as to be beneficial to tight alignment of the anastomosing ports in surgery.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, be specifically related to a kind of magnetic devices that is applicable to aorta anastomosis.
Background technology
Aorta anastomosis is but still continued to use the identical method of craft before more than 100 year in the traditional operation, become the aorta anastomosis technology of main flow now, though very big progress has been arranged in the selection of suture material, but this traditional manual suture method still fails to meet fully ideal vascular anastomosis principle, the speed of not only coincideing is slow, also may cause occurring in the art serious hemodynamics and interior environment disorder, operation wound is bigger, inflammatory mediator release, when particularly in capital operation, needing the trunk of depths in the identical body cavity, can cause the organ ischemic necrosis because of long-time blocking blood flow, or the congestion edema causes the anastomotic stoma oozing of blood, or postoperative the Secondary cases massive hemorrhage occurs because of the ligature slippage, and postoperative also can cause local granulation tissue reaction and hypertrophy because of ligature retains in vivo, has increased the weight of patient's body injury; Also may cause the damage of blood vessel wall to form various complication such as false aneurysm in addition, influence anastomotic healing, and manual coincideing also needs operator to have higher surgical operation skill.These shortcomings are still affecting the various long-term efficacies that relate to vascular anastomosis so far.But in art, utilize the device that just has only simple cylindric vascular anastomosis the manual anastomosis of blood vessel of suture so far, the operating theater instruments that this cylindrical-shaped structure is not easy in the operation process grips, particularly be unfavorable for very much the aorta anastomosis operation in body cavity deep, cause the long and big shortcoming of identical difficulty of surgical stapling time, thus the serious unsuccessful consequence that causes angiorrhexis to cause severe loss of blood of vascular anastomosis that also can cause.
Summary of the invention
In order to overcome the deficiency that above-mentioned prior art exists, the object of the present invention is to provide a kind of magnetic devices that is applicable to aorta anastomosis, utilize two the elliptical cylinder-shape anastomosis ring that include permanent magnet corresponding to finish coincideing of different tube diameters blood vessel with the caliber of trunk to be coincide, two level and smooth polishings of permanent magnet anastomosis ring opposite face make tunica intima neatly involutory, avoid manual sutures to coincide being brought anastomotic stricture, seepage blood, the ligature slippage causes massive hemorrhage, the local organization granuloma, the shortcoming that complication such as false tremulous pulse formation are many, because anastomosis ring is designed to elliptical cylinder-shape, be convenient to use in the art operating theater instruments to grip, be beneficial to very much the aorta anastomosis operation in body cavity deep, and utilize this anastomat to carry out more identical person of spent time of aorta anastomosis and will shorten more than 5 times, avoided histoorgan to cause organ dysfunction because of long-time blocking blood flow causes operation of organ ischemia or congestion edema.The close apposition of the anastomotic stoma during coniform titanium alloy pin of employing and corresponding coniform aperture help performing the operation on the end face in addition.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of magnetic devices that is applicable to aorta anastomosis, form by two elliptical cylinder-shape permanent magnet anastomosis ring, two permanent magnet anastomosis ring respectively comprise a shape size unanimity and have the aperture with the polypropylene column shell 2 for the treatment of the elliptical cylinder-shape hollow hole 5 that anastomosis of blood vessel 11 calibers are consistent, this column shell 2 has cylindroid annular groove 6 on an end face, this end face just is divided into outer face and inner face two parts by cylindroid annular groove 6 like this, this cylindroid annular groove 6 be embedded with its central axis with the corresponding to cylindroid annular permanent magnet 1 of these cylindroid annular groove 6 central axis, the magnetic of the permanent magnet 1 of these two elliptical cylinder-shape permanent magnet anastomosis ring is opposite, an end face of permanent magnet 1 is mutually concordant with inner face with described outer face, in addition at the outside coniform titanium alloy pin 7 of vertebra point that also is distributed with on the outer face more than three, have an inside coniform aperture 4 of vertebra point on the outer face between two adjacent titanium alloy pins 7, the outer surface of coniform aperture 4 positions of the titanium alloy pin 7 of each elliptical cylinder-shape permanent magnet anastomosis ring and another elliptical cylinder-shape permanent magnet anastomosis ring coniform titanium alloy pin 7 that mirror image is corresponding and corresponding one by one and the inner wall shape size of coniform aperture 4 are consistent.
Finish coincideing of different tube diameters blood vessel by utilizing two elliptical cylinder-shape anastomosis ring that include cylindroid annular permanent magnet 1 corresponding with the caliber of trunk to be coincide, two level and smooth polishings of permanent magnet anastomosis ring opposite face make tunica intima neatly involutory, avoid manual sutures to coincide being brought anastomotic stricture, seepage blood, the ligature slippage causes massive hemorrhage, the local organization granuloma, the shortcoming that complication such as false tremulous pulse formation are many, because anastomosis ring is designed to elliptical cylinder-shape, be convenient to use in the art operating theater instruments to grip, be beneficial to very much the aorta anastomosis operation in body cavity deep, and utilize this anastomat to carry out more identical person of spent time of aorta anastomosis and will shorten more than 5 times, avoided histoorgan to cause organ dysfunction because of long-time blocking blood flow causes operation of organ ischemia or congestion edema.The close apposition of the anastomotic stoma during coniform titanium alloy pin of employing and corresponding coniform aperture help performing the operation on the end face in addition.
