Description
Technical field
This utility model is related to medical instruments field, particularly a kind of medical double-sleeve pipe device.
Background technology
At present abdominal surgery postoperative drainage pipe species is various, for appropriate use drainage tube can reduce post-operative complication.
The postoperative conventional drainage way of abdominal surgery has three kinds：(1) cigarette drain, be generally used for sepage it is less when.(2) tubulose
Drain, is generally used for that sepage is more, thick thick one, and drainage time is longer.(3) ditube drainage.Continual rinsing double-jacket tube negative pressure
Drain can in time, thoroughly discharge wound chamber hydrops and slough, make wound surface or vomica keep efficient drain, wound chamber to reduce, promote
Enter wound healing.Being clinically used for the disease of abdominal surgery has small bowel fistula and a fistula of colon, abdominal cavity and Soft Tissue Abscess: An Experimental-subphrenic abscess,
Pelvic abscess, soft tissue deep abscess, wound and capital operation for example hepatic portion excision and kposthesiss, duodenum kposthesiss,
Technique in Abdomino-perineal Resection for Cancer of Rectum, acute critical pancreatitis drainage, radical surgery of carcinoma of pancreas head, severe multiple injuries and hollow organ
Damage postoperative etc..
The principle of double-jacket tube negative pressure drainage is the outer tube that a porous is cased with outside the inner sleeve with negative pressure suction force, interior
There are a 3-6mm widths between outer tube wall, air can be appointed to enter unobstructedly.Trocar sheath plays a supportive role, and using breast/silica gel tube, keeps away
Exempt from intestinal wall or tissue is damaged and blocked by vacuum suction suction catheter.Many side openings of surrounding are conducive to expanding attractived region, make double
Its vicinity produces omnibearing negative pressure, promotes the formation of sinus tract.When intraperitoneal has liquid, liquid is by from the porous of trocar sheath
It is middle into inside and outside ligament, then by with negative pressure inner tube absorb.When intraperitoneal no liquid, suction catheter is aspirated between inner and outer pipes
Gap enter air, so, Intraabdominal tissue, organ not with the inner tube directly contact with negative pressure, tissue quilt will not occur
Negative suction pipe and be damaged.Double-set abdominal cavity inner casing tube is thinner, acts primarily as the effect of attraction, and by negative pressure Intraabdominal drawing is made
Stream thing is removed in time, the particularly big blood of viscosity, is just suctioned out by negative pressure before not solidifying, and can be reduced tissue occlusion and be drawn
Flow tube duct.But drainage-fluid contains cellulose tissue chip, slough, thrombin activity material, itself can block tube chamber.And
And the moisture of these materials blotted by negative pressure after be more easy in the inner sleeve of lacuna blocking so as to prematurely lose drain work
With.It is difficult to change during blocking, often results in drain failure.
At present, in abdominal surgery, particularly liver and gall pancreas surgery, the use of double-jacket tube is wide, but necrosis, slough tissue
Or sludged blood Chang Yi blocks double-jacket tube inner tube.Particularly surgery of liver row Hepatectomy, liver wound surface or abdominal cavity hemorrhage,
Hematocele has little time to suction out, and blood clot quickly will block inner sleeve suction hole, causes postoperative clinical observation difficult.Meanwhile, now
The more double-jacket tube of Clinical practice, inner tube changes relatively difficult once blocking, and easily causes double-jacket tube displacement and retrograde infection, because
And have to for double-jacket tube to be changed to single lumen catheter, lose the effect of continual rinsing drain.
