The circular sshivayushche-cutting devices Ethicon Endo-Surgery CDH_A-SDH_A
The circular sshivayushche-cutting devices are intended for formation of circular anastomoz of type "the end in the end", "the end sideways". Devices with an external diameter of head of 21, 25, 29, 33 mm are issued. For adaptation to concrete clinical situations and taking into account preferences of surgeons each model is produced in two modifications: with straight lines (SDH, Es-Dee-Eych) and bent (CDH, Si-Di-Eych) a trunk. Length of devices allows to form anastomoza from the place of introduction of the device at a great distance. The circular sshivayushche-cutting devices form a two-row circular mechanical seam by means of the brackets from titanic alloy located in chessboard order. The edge from steel of the 400th series guarantees the most careful formation of an anastomoz. The compressions of fabrics regulated degree and height of closing of brackets promote adequate compression of fabrics, the correct formation of brackets, providing a reliable hemostasis, good blood supply in a zone of an anastomoz and its tightness. Existence of tactile and sound indication of a proshivaniye allows the surgeon to control process of formation of an anastomoz. Troakar is built in a working part of circular devices that promotes atraumatic introduction of the tool to a gleam of hollow body. Existence of an additional troakar in a delivery set for carrying out a head of the device through a wall of hollow body. Formation of an adequate internal gleam of an anastomoz, a low profile of a removable head, the mechanism of bystry opening and closing of the device provide safe extraction of the device from a zone of an anastomoz. The rubberized handles and ergonomic design of devices are developed for convenience of work of the surgeon. Thanks to simplicity of formation of anastomoz and usability the circular sewing devices widely are used when forming gastroentero-and gastroduodenoanastomoz, a resection obodochny, sigmovidny and a rectum, in many cases allowing to avoid imposing of an external stoma. PPH is modification of the circular sewing device with not separated head adapted for carrying out a circular resection of a mucous rectum and surgical treatment of hemorrhoids. Having all advantages of the circular sewing devices, RRN allows to create wide mucous and submucous anastomoz a rectum above the gear line. One of the most significant characteristics of the devices PPH is the adjustable height of closing of brackets that provides individual approach to fabrics of various thickness and promotes a reliable hemostasis. Gemorroidopeksiya across Longo with use of RRN is characterized by considerable decrease in expressiveness intra-and a postoperative pain syndrome and bystry return of the patient to a normal way of life.
The circular sshivayushche-cutting devices with a direct or curved trunk providing formation of a 2-row skobochny seam with adjustable height of closed bracket from 1,0 to 2,5 mm by means of brackets of the In-shaped form from titanic alloy with a simultaneous section of fabric
surgical interventions on a gullet, a stomach and intestines
Removable golovkadiametr heads: 21 mm, 25 mm, 29 mm, 33 mm
Trunk length: 180 mm
Trunk form: direct, curved
Quantity of rows of a skobochny seam: 2
Height of closing of brackets: regulated 1,0-2,5 mm
Height of a leg of an open bracket: 5,5 mm
Material of brackets: titanic alloy
Total of proshivaniye: 1
QUALITATIVE MECHANICAL SEAM:
Tselnolity basic part of a head of the device and adjustable height of closing of a bracket provide controlled degree of a compression of the sewn fabrics that guarantees high-quality formation of brackets of uniform height on all length of a seam.
Properties of titanic alloy from which brackets are produced prevent the return opening of already created brackets.
Height of a leg of an open bracket, greatest in class (5,5 mm) allows to form brackets even during the work with thick fabrics.
FLEXIBILITY AND USABILITY:
Adjustable degree of a compression of fabrics, and also presence of 4 various diameters of a head of the device allow to adapt to any clinical situation.
Well visualized compression scale with marking on height of the closed bracket simplifies use of the device.
The antiskid covering and ergonomic design facilitate use and control of the device.
The removable low-profile head provides ease of introduction of a working part to a cavity of body.
The cut laying provides tactile and sound control at a proshivaniye and a section of fabrics.
Existence of a safety lock interferes with a casual proshivaniye.
Thanks to a wide gleam of an anastomoz and a narrow anastomotichesky lip the device is easily taken from the created anastomoz without extras.
