Description
Technical field
The present invention relates to a kind of magnetic pressure to squeeze anastomosis ring.More particularly to one kind there is fastening-type bolt and concealed safety to justify
The fastening of knife, which declines, follows closely magnetic pressure squeezing anastomosis ring.
Background technology
China's hemorrhoid incidence of disease is higher, and with age, its incidence of disease also gradually increases.As Chinese society is old
Age degree is aggravated, and the problem can be protruded more and more.It is current III-IV degree prolapsed internal hemorrhoids mainly uses operative treatment, in the past with
Based on Milligan-Morgan methods, Italian scholar Longo in 1998 proposes mucous membrane ring cutting in the hemorrhoid using titanium nail circular staplers first
Art (Procedure for prolapse and hemorrhoids, PPH).PPH is relaxed straight by stapler circular resection
Intestines lower end mucous membrane and submucous tissue, while being coincide to remote, near-end mucous membrane, anus pad is elevated, is suspended in again straight
Intestines lower end, recover the normal anatomical structures of mucous membrane of anal canal and sphincter, improve anus self-control function.Confession is also cut off simultaneously
The Major Vessels of hemorrhoid are answered, reduce CBF under mucous membrane, the postoperative gradual atrophy of haemorrhoids.PPH, which has, does not destroy anus pad normal physiological work(
The advantages that, podex anatomical physiology being met, be simple to operate, short term effect is good, promoted rapidly in the world.
But gradually found during the Clinical practice of nearly 20 years thereafter, circular titanium nail stapler row PPH is postoperative,
Titanium follows closely long period indwelling, easily causes the complication such as bleeding, intractable anus pain or falling inflation, narrow, infection, the retention of urine,
And recurrence prolapsus rate height, continuous bleeding for a long time also be present, the stricture of anus, fecal incontinence, chronic ache, perform the operation is remained again
The major defect that titanium nail influences.And titanium nail stapler complex manufacturing, titanium nail is tiny, and quantity is more, and yield rate is difficult to reach
To 100%, de- nail is caused to directly result in the severe complications such as bleeding or anastomotic leakage.Therefore, circular titanium nail stapler is straight in knot
Enterochirurgia field, especially for mucosectomy in hemorrhoid, arrived need update when.
Squeezing property anastomosis (including nail ring, memorial alloy ring, degradable ring, magnet ring etc.) preferably solve above-mentioned lack
Fall into.Squeezing property anastomosis principle is that surrounding tissue growth healing, anastomosis ring gradually takes off thereafter by squeezing site tissue necrosis
Fall, form squeezing previous anastomotic.The common disadvantage for following closely ring, memorial alloy ring and degradable ring is that structure is more complicated, and volume is slightly larger, because
This causes stenosis of bowel, discharge difficult.And gradual, non-penetrating type squeezing can not be formed, healing is slower.
Magnet ring, which coincide, belongs to uniform, lasting, non-penetrating, gradual squeezing healing, it is advantageous that magnet ring finally can be with excrement
Just excrete, do not remain any foreign matter, the defects of avoiding titanium nail stapler foreign matter permanent indwelling.And it coincide and subtracts compared with titanium nail
Bleeding, the risk of infection are lacked.It is earliest that Dutch Jansen etc. was used in 1981 for alimentary tract anastomosis that magnetic squeezing, which coincide,
Cobalt permanent magnet magnetic pole and supporting polymer inner support, external diameter 25,28 and 30mm (internal diameter is respectively 13,15 and 17mm), it is 21
Example patient (average age 65.8 years old) implements clinical low level colorectolostomy.As a result postoperative 7-12d, magnet ring are arranged with stool
Go out.As a result postoperative have 1 patient's previous anastomotic to split to perform the operation again, and 1 patient's previous anastomotic meroblastic cleavage is opened, the postoperative 3d hearts of 1 patient
Infarct is died, and remaining 18 patient, which fully recovers, to leave hospital.But due to magnetic material limitation at that time, magnetic force is weaker, and magnetic pole volume is larger, weight
To measure heavier, internal diameter smaller (only 13-17mm) easily causes to block, and the fastener such as non-bolt, clinical safety are under suspicion,
Thereafter gradually go out of use.
Patent applicant in 2006 successfully carries out dog liver transfer operation Great vascular reconstruction (Transplant using magnetic anastomosis rings
Proc.2006Nov；38(9):3070-4), patent applicant in 2013 successfully carries out rats'liver shifting using magnetic anastomosis rings again
Plant Major Vessels and rebuild (Transpl Int.2015 Jan；28(1):89-94), blood vessel healing rate is very fast, and healing quality is good
It is good.Thus the Research foundation of hemorrhoid cirso- group resection and anastomosis has been established.In the same year, permit through patent applicant, Geng Shu '
An etc. has carried out the experiment of mucous membrane ring cutting in pig hemorrhoid using two simple magnet rings on this basis, works well, all magnet rings are equal
(Surg Today.2015 Jan are smoothly excreted in postoperative 7-10d；45(1):78-82).At present, magnetic anastomosis exist
Had been widely used in world wide Cholangio- jejunostomy, vascular anastomosis, coronary bypass, gastrointestinal anastomosis, lemostenosis dredging,
The fields such as Gastroesophageal Reflux treatment.The studies above is as the most important theories basis of this patent.
But the magnetic stapling apparatus referred to due to previous literature or patent, which is used for hemorrhoid, to coincide etc. and to remain in open defect,
Most magnetic stapling apparatus be two simple magnet rings, it is difficult to meets clinical safety, the accurate requirement such as reliable, apart from clinical practice
It is still remote, it is necessary to solve following problem：
1) cardinal principle of magnet ring clinical practice is to be unable to that magnetic force is excessive to be caused to come off in advance, can not magnetic force is too small causes
Previous anastomotic disengages, slips or misplaced, and these belong to severe complication.
2) magnet ring feature itself is that magnetic force is decayed rapidly as tissue thickness increases, and hemorrhoid nearby have inflammation water more
Swollen, the venous group of varicose causes tissue thicker in addition, hence it is evident that weakens magnetic attracting force, easily causes previous anastomotic to disengage.And with
The regression of previous anastomotic inflammation oedema and the necrosis by squeezing tissue, magnetic attracting force is increasing, and necrosis is more and more faster, and is cured
Sum velocity is not accelerated, therefore is easily come off before healing.And each the age of patient, tissue thickness, body weight etc. differ,
Therefore need solve this great problem.
3) magnet ring own material is mostly neodymium iron boron or other rare earth materials, exists and is easily disintegrated, is difficult to Precision Machining, holds
The defects of easily being corroded by human internal environment.
If 4) add thicker common metal shell, local magnetic screen is easily caused, has a strong impact on the magnetic force of magnet ring.
5) other magnet rings lack fastener in addition, in the case where organizing thicker or oedema, easily disengage, serious shadow
Ring Clinical practice security.
