Abstract
The utility model discloses a kind of Genneral Surgery ball-bag dilation tube, comprise catheter proximal end, conduit middle-end, distal end of catheter and air bag, conduit middle-end outer wrap has air bag, distal end of catheter is tapered, air bag is the edge of snowflake sheet shape on the cross section vertical with axis, edge is round and smooth and on same circumference, after air bag is full, form multiple passage, the outer surface of the edge protuberance of air bag is irregular is distributed with several salient points, salient point is biological or medication coat, and edge is 4 to 8 lobes, and catheter proximal end is connected with threeway handle.This utility model structure is simple, reasonable in design, sacculus after expansion can not block this section of biliary tract completely, the air-flow in biliary tract is made still to be in maintenance circulation status, anti-extrusion performance improves, the outer surface of edge protuberance is irregular is distributed with several for biological or medication coat salient point, and increase friction, security performance is high.
Description
Technical field
This utility model relates to field of medical article technology, is specifically related to a kind of Genneral Surgery ball-bag dilation tube.
Background technology
At present, known sacculus dilating catheter clinically, is mainly used in recovering the expansion at human body Stenosis position, as blood vessel, urinary catheter, biliary tract, trachea, fallopian tube, esophagus etc., also has for calculus of bile duct treatment.
In the recent period, to the biliary tract stenosis after biliary duct injury and liver transplantation, a kind of method of gradual biliary tract expansion is newly used to clinically achieve satisfied curative effect.Its principle is exactly in biliary tract, place dilating sacculus by the method for operation, and a period of time implements to be interrupted to narrow bile duct after surgery, not only gradual expansion, reaches the effect of expansion biliary tract but also biliary tract can not be made downright bad due to long-time pressurized.But this sacculus all blocks biliary tract when filling, cause sacculus inside and outside formation pressure reduction, be easily shifted after placement.When sacculus is just difficult to again it be put back to original position once depart from operating position, cause operative failure.In addition, even if sacculus is not shifted, if but there is at treatments period damages such as breaking in sacculus, will thoroughly lose the effect for the treatment of, the foley's tube being difficult to more renew is to narrow positions.
Utility model content
The purpose of this utility model provides a kind of circulation that can not only maintain air-flow in this biliary tract while expansion biliary tract with regard to being, eliminates biliary tract clogging, also has Genneral Surgery's ball-bag dilation tube that wear-resisting resistance to pressure is good, safety is high simultaneously.
The technical scheme taked for this utility model that solves the problem is to provide a kind of Genneral Surgery ball-bag dilation tube, comprise catheter proximal end, conduit middle-end, distal end of catheter and air bag, described conduit middle-end outer wrap has air bag, described distal end of catheter is tapered, described air bag has the edge in snowflake sheet shape on the cross section vertical with axis, described edge is round and smooth and on same circumference, after air bag is full, form multiple passage, the outer surface of the edge protuberance of described air bag is irregular is distributed with several salient points, described salient point is biological or medication coat.
Preferably, described edge is 4 to 8 lobes.
Preferably, described catheter proximal end is connected with threeway handle.
Preferably, the material of described air bag is polyurethane elastomer, nylon, block polyether acidamide resin, polyolefin or polyester.
The beneficial effect adopting technique scheme to produce is: this utility model structure is simple, reasonable in design, the dredging the planning function of general general ball-bag dilation tube can not only be had, more because sacculus edge is 4 to 8 lobes, after sacculus is full, form multiple passage, make the sacculus after expansion can not block this section of biliary tract completely, the air-flow in biliary tract is made still to be in maintenance circulation status, anti-extrusion performance improves, the outer surface of edge protuberance is irregular is distributed with several for biological or medication coat salient point, and increase friction, security performance is high.

Detailed description of the invention
Referring to accompanying drawing, provide detailed description of the invention of the present utility model, be used for being further described formation of the present utility model.
As shown in the figure: a kind of Genneral Surgery ball-bag dilation tube, comprise catheter proximal end 1, conduit middle-end 2, distal end of catheter 3 and air bag 4, described conduit middle-end 2 outer wrap has air bag 4, described distal end of catheter 3 is tapered, described air bag 4 is the edge 5 of snowflake sheet shape on the cross section vertical with axis, described edge 5 is round and smooth and on same circumference, after air bag 4 is full, form multiple passage 9, the outer surface of the edge protuberance 6 of described air bag 4 is irregular is distributed with several salient points 7, and described salient point 7 is biological or medication coat.
Preferably, described edge 5 is 4 to 8 lobes.
Preferably, described catheter proximal end 1 is connected with threeway handle 8.
Preferably, the material of described air bag 4 is polyurethane elastomer, nylon, block polyether acidamide resin, polyolefin or polyester.
The beneficial effect adopting technique scheme to produce is: this utility model structure is simple, reasonable in design, the dredging the planning function of general general ball-bag dilation tube can not only be had, more because sacculus edge is 4 to 8 lobes, after sacculus is full, form multiple passage, make the sacculus after expansion can not block this section of biliary tract completely, the air-flow in biliary tract is made still to be in maintenance circulation status, anti-extrusion performance improves, the outer surface of edge protuberance is irregular is distributed with several for biological or medication coat salient point, and increase friction, security performance is high.
Embodiment recited above is only be described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from this utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of this utility model request protection, all records in detail in the claims.
