Fixation device for blood vessel cut
Abstract
Abstract Translated from Japanese (57)【要約】 【課題】 血管切断部を一定の厚さの断面正円形に整形 すべく固定する。 【解決手段】 固定器1は、エアの送入、排出によって 拡縮し、縮小時に血管a端部内側に挿入可能な拡縮体た るゴムサック2と、このゴムサック2を支持しその口部 2aを経てゴムサック2内に連通するエア流通路を備え た支持部3と、前記エア流通路を介してゴムサック2内 にエアを送入するためのエア供給部4とを備える。血管 a切断面から補強用接着剤を注射し前記ゴムサック2を 血管a切断部の内側に挿入した後、エア供給部4を作動 させてゴムサック2内にエアを送入して拡張させ血管a 切断部を整形すべく固定する。前記接着剤が固化した ら、両血管a切断部に人工血管両端を縫合する。血管a 切断部は、その内側で拡張したゴムサック2によって押 し広げられ一定の厚さの断面正円形に整形される。 (57) [Summary] [PROBLEMS] To fix a cut section of a blood vessel so as to form a circular cross section of a certain thickness. SOLUTION: A fixing device 1 expands / contracts by feeding and discharging air, and a rubber sack 2 which is an expandable / contractible body which can be inserted inside an end of a blood vessel a when contracted. The rubber sack 2 supports the rubber sack 2 and passes through a mouth 2a thereof. A support portion 3 having an air flow passage communicating with the inside of the rubber sack 2 and an air supply portion 4 for feeding air into the rubber sack 2 through the air flow passage. After injecting the reinforcing adhesive from the cut surface of the blood vessel a and inserting the rubber sack 2 inside the cut portion of the blood vessel a, the air supply unit 4 is operated to feed air into the rubber sack 2 to expand the blood vessel a. Fix the cut to shape. When the adhesive solidifies, both ends of the artificial blood vessel are sutured to the cut portions of both blood vessels a. Blood vessel a The cut portion is pushed and spread by the rubber sack 2 expanded on the inside thereof, and is shaped into a circular section having a constant thickness.
