Abstract
Disclosed is a soft bile duct support for bile duct drainage. One end of the soft bile duct support is a bile duct fixing portion in screw shape or C shape, the other end is a duodenum fixing portion in J shape or C shape, and a drainage section is placed between the two fixing portions. A screw-shaped or C-shaped structure has supporting and fixing functions inside a bile duct and prevents the support from slipping or slipping untimely, a J-shaped or C-shaped structure prevents the support from reversely entering the bile duct inside a duodenum cavity, and the J-shaped or C-shaped structure accelerates the support to shed punctually under the action of chime promotion and intestinal peristalsis. According to the demand of clinical bile duct drainage time, different duodenum fixing portions and bile duct fixing portions with different spiral degrees, spiral distances and C-shaped radians are designed. The support can substitute for T-shaped ducts in common bile duct exploratory operation and can also reversely enter the bile duct under a duodenal endoscope or can be directly placed in the bile duct through percutaneous transhepatic cholangiography puncture. The support can be used for surgical treatment for common bile duct stone choledocholith, preoperative biliary drainage for obstructive jaundice, palliative treatment for late malignant obstructive jaundice and non-surgical treatment for acute cholangitis.
Description
Technical field:
This utility model relates to a kind of soft biliary tract rack that is used for biliary drainage.
Background technology
At present, known biliary tract rack has three kinds: a kind of is as the memory alloy stent of long-term drain, costs an arm and a leg, and can not take out after it is once put into again, and is only applicable to the palliative therapy of pernicious obstructive jaundice in late period clinically.Another kind is the plastic stent of hard, and moderate cost is used extensivelyr, and its two ends band agnail (or Christmas is tree-shaped) plays fixation, and an end is in bile duct, and the other end is in duodenum, and the agnail at two ends prevents from the support slippage or drive in the wrong direction to enter in the bile duct; Under duodenoscope, drive in the wrong direction during application and insert bile duct, be used for subtracting before the operation of obstructive jaundice the medium-term and long-term supporting drainage treatment of Huang or good, pernicious biliary tract stenosis or carcinoma of head of pancreas.In recent years, when the choledocholithiasis operative treatment, substitute traditional T type Tube Drain both at home and abroad with this kind plastic stent, in the art support is inserted common bile duct far-end and duodenum through the direct motion of common bile duct otch, again with the common bile duct primary closure, obtained clinical effectiveness preferably: both avoided the inconvenience of patient at external long-term band T type pipe, prevented the generation that gallbladder leaks behind the direct primary suture again, the range of application of this kind support is further enlarged.But the shortcoming of plastic stent is to come off voluntarily, all need be after finishing therapeutic purposes under duodenoscope again with its taking-up (Zhang Kai, Wang Haowei, Wu Haorong etc. use the feasibility study of the capable laparoscopic common bile duct exploration of biliary stent.China Genneral Surgery magazine, 2006,12 (1): 21-23.Tang CN, Tai CK, Ha JP, et al.Antegradebiliary sgtenting versus T-tube drainage after laparoscopiccholedochotomy-a comparative cohort study.Hepatogastroenterology2006 May-Jun; 53 (69): 330-334.), increased patient's misery and financial burden.Hard because of the support quality again, in storing and taking-up process, the risk that causes duodenal injury is arranged.The third support is biliary tract that the inventor the designs support tube (patent No.: ZL200620072773.1) that comes off voluntarily, efficiently solve the problem that to get support again when being used for the choledocholithiasis operative treatment, support can come off after operation and discharge (Tian Mingguo with feces in 2 weeks voluntarily, Zhong Chongjun, Yang Junfeng etc., laparoscopic common bile duct exploration improvement biliary tract rack drainage, China Genneral Surgery magazine 200814 (9): 661-662), but, the biliary tract support tube that comes off voluntarily only limits to use in the exploration of common bile duct operation, can't under duodenoscope, drive in the wrong direction and insert, and the time that support comes off is constant, can not adjust the time of coming off according to the clinical treatment needs.Therefore, range of application is limited to.
Summary of the invention:
Cost an arm and a leg, use limitation in order to solve existing memory alloy stent, existing rigid plastics support quality is too hard, can not come off voluntarily and the existing biliary tract deficiency of limitation of support tube range of application that comes off voluntarily, this utility model provides a kind of soft biliary tract rack, this support is direct motion or drive in the wrong direction and to insert the drain position by all means both, can in different time, come off voluntarily or keep long-term drain and do not come off according to clinical needs again, softer because of quality, when placing and take out, can not cause intestinal injury.
Technical solution of the present utility model is: adopt soft conduit full of elasticity, that the lighttight medical macromolecular materials of radiation are made to make biliary tract rack, one end is bile duct fixed part type or a C type in the shape of a spiral, the other end is J type or C type for the duodenum fixed part, be the Drainage Section between two fixed parts, a plurality of drain side openings are established in two fixed parts and the outside thereof at support, and the support that is used for long-term drain is the attached superslide coating of outer wall surface within it.Thereby the bile duct fixed part stops support displacement slippage according to forming frictional resistance between the elasticity tension of helical structure or C type structure and the bile duct wall in bile duct, and the duodenum fixed part plays and stops support to drive in the wrong direction to the biliary tract internal shift and promote the dual function that support comes off.
Needs according to the biliary tract drainage time are designed to different bile duct fixed parts and duodenum fixed part, thereby satisfy different clinical treatment demands.The strong point of the spiral-shaped structure of bile duct fixed part in bile duct is laterally or arranged askew, and supporting surface is bigger, and the frictional resistance that produces when the support force tractive is bigger, thereby support is not easy early fallout.The time that support comes off is depended on the spiral number of degrees and the helix pitch of helical structure.The spiral number of degrees are big more, helix pitch is more little, supporting surface and the support force of support in bile duct is just big more, thereby the frictional resistance of helical structure and bile duct inwall is big more, and the resistance that helical structure produces during by narrow section or vater's papilla is also big more, and support is difficult for slippage more; Otherwise the spiral number of degrees are more little, helix pitch is big more, and the resistance that the frictional resistance of helical structure and bile duct inwall is just more little, helical structure produces during by narrow section or vater's papilla is also more little, therefore, and the easy more slippage of support.The strong point of C type structure in bile duct of bile duct fixed part is vertical arrangement, and supporting surface is less, the frictional resistance of its generation is little than helical structure when support is subjected to tractive, the easy early fallout of support, the time that comes off depends primarily on the radian of C type structure, when arc length was constant, radian was big more, and its support force to bile duct wall is big more; Radian is more little, and then support force is more little.Therefore, can control the time that support comes off by the radian of adjusting C type structure.The ring-type J type structure of duodenum fixed part is easily promoted by chyme in duodenum, drives support easily and comes off; And that C type structure is met the resistance that produces when chyme promotes is little, makes support be not easy to be pushed and holds time longlyer, can be used for long-term biliary tract drain.Therefore, C type-J support is held time the shortest, and spiral-C type support is held time the longest, and spiral-J support is held time between two parties.Be used for long-term or permanent spiral of inserting-C type support within it the attached superslide coating of outer wall surface can prevent that support from being stopped up by heavy-gravity bile or muddy stone.
When clinical practice, can in operation, in duodenum, insert seal wire through the common bile duct otch under the choledochoscope, or in biliary tract and duodenum, insert seal wire by the puncture direct motion of percutaneous liver and gall road during non-operation, or under duodenoscope, drive in the wrong direction and in bile duct, insert seal wire, again support is entangled seal wire and push the position that is fit to the biliary tract drain, withdraw from seal wire after-poppet its spiral of elastic recovery J type or C type structure at once with the propelling movement pipe.
The beneficial effects of the utility model are, can take the support of different bile duct fixed parts and different duodenum fixed parts according to the needs of clinical biliary tract drain, make it to come off voluntarily in different time or do not come off for a long time.In the bile duct exploration art, can replace traditional T type pipe, avoid the related complication of T type Tube Drain and patient, can obviously reduce the risk that gallbladder leaks behind the exploration of common bile duct primary closure for a long time with the inconvenience of drainage tube; Support drives in the wrong direction under duodenoscope and inserts per nasal biliary tract drain (ENBD) under alternative existing rigid plastics support of biliary tract and the alternative scope, because of quality soft, when placing, come off or taking out, intestinal injury can not be caused, bile loss and patient discomfort can be avoided behind the alternative ENBD with the nose conduit.Support also can puncture through the liver and gall road by percutaneous and insert the biliary drainage position, is used for the palliative treatment of pernicious obstructive jaundice.The patient of exploration of common bile duct T type Tube Drain postoperative common bile duct far-end benign stricture, can pull out T type pipe after under choledochoscope, inserting this support, thereby avoid long-term a large amount of bile losses by T type pipe sinus tract.
