Chip 201 is used for controlling filled media 300 being filled with to filled type Control of Hemorrhage in Laparoscopic Liver door bloodstream blocking with 100.
Also, include data base in Digital Control chip 401（It is not specifically illustrated）, in the data base, store liver and gall
Hepatoduodenal ligament week footpath delta data before and after pringle maneuver in operation.And, Digital Control chip 401 is according to filling out
Fill formula Control of Hemorrhage in Laparoscopic Liver door bloodstream blocking tough with hepatoduodenal before and after pringle maneuver in 100 size and hepatobiliary surgery
Filled media 300 is controlled in real time with all footpath delta datas to be filled with to filled type Control of Hemorrhage in Laparoscopic Liver door bloodstream blocking with 100, example
As calculated automatically the filled media volume that need to be filled with, so as to automatically control filled media to filled type Control of Hemorrhage in Laparoscopic Liver door blood flow
Block being filled with for band.
The specific embodiment of filled type Control of Hemorrhage in Laparoscopic Liver door bloodstream blocking band is described below in conjunction with accompanying drawing.
Referring to figs. 2 to Fig. 7, filled type Control of Hemorrhage in Laparoscopic Liver door bloodstream blocking band according to the preferred embodiment of the invention includes length
Bar shaped tubular body 100；The wherein first end 101 in the longitudinal direction of strip tubular body 100 is opened, strip tubulose master
The second end 102 in the longitudinal direction of body 100 is closed, so as to form the inner space with the opening at first end 101.
Strip tubular body 100 is with by the opening at the first end 101, internally space is filled with filled media (example
Such as, filled media includes but is not limited to air, CO2Or normal saline) when expanded state.
And, on the section perpendicular with the length direction of strip tubular body 100, strip tubular body 100
The first side 10 wall thickness less than strip tubular body 100 the second side 20 wall thickness；Thus under expanded state, the
Expansion rate of the expansion rate of the wall of side 10 more than the wall of the second side 20.
Wherein it is preferred to, the strip tubular body 100 is flexible body.
Preferably, the material of the strip tubular body 100 is medical silica-gel.
Preferably so that the wall thickness of the second side 20 of strip tubular body 100 is at least strip tubular body 100
Five times of wall thickness of the first side 10 so that filled type Control of Hemorrhage in Laparoscopic Liver door bloodstream blocking band basic upper table under expanded state
It is now unidirectional expansion.
It is further preferred that so that the wall thickness of the second side 20 of strip tubular body 100 is at least strip tubulose
Ten times of the wall thickness of the first side 10 of main body 100, can now better ensure that unidirectional dilatancy.
On the other hand, it is preferable that for the selection of the wall thickness of the wall thickness and the second side 20 of the first side 10, can not have
Body limits the ratio of thickness, and can be the five of the expansion rate at least expansion rate of the wall of the second side 20 of the wall for causing the first side 10
Times；It is highly preferred that ten times of the expansion rate at least expansion rate of the wall of the second side 20 of the wall of the first side 10 can be caused.
And, further, as shown in Figure 6 and Figure 7, it is preferable that connecting tube 200 and the strip tubular body 100
First end 101 at opening connection.
It is further preferred that the connecting tube 200 is connected releasably to and the strip tubular body 100
First end 101 at opening, so can be more convenient when concrete operation.
So, as shown in Figure 6 and Figure 7, if the present invention filled type Control of Hemorrhage in Laparoscopic Liver door bloodstream blocking band use when
Which stays 200 filled media of connecting tube outside abdominal cavity, by its one end（The first end of opening）Stay outside abdominal cavity, remaining major part is put
Intraperitoneal is inserted, around all or part hepatoduodenal ligament；Which can be made to be positioned over intraperitoneal and tentatively tie up whole
Or the part of part hepatoduodenal ligament B fills；Wherein, thin-walled side（First side 10）It is towards hepatic portal blood flow, inwardly unidirectional swollen
It is swollen, block the bile flow of Hepatic artery C, the blood flow of portal vein D and common bile duct E in hepatoduodenal ligament；Realize hepatic portal blood flow
The effect of blocking.Aforesaid operations are simple, quick, and barrier effect is thorough.Filled type Control of Hemorrhage in Laparoscopic Liver door bloodstream blocking band is in addition
One soft ribbons（Flexible body）, an operation path and certain intraperitoneal space is not take up, follow-up operation technique is not affected.This
Invention overcome existing various simple Porta hepatis blockers do not allow under peritoneoscope it is easy to operate, hepatoduodenal ligament tie up knotting,
Clamp is not firm enough, blocking not thoroughly, the shortcomings of subsequent operation may be affected.
On the basis of above-mentioned filled type Control of Hemorrhage in Laparoscopic Liver door bloodstream blocking band, the infusion pump with Digital Control chip
400 automatically control filled media is carried the connecting tube of check valve and is injected by high pressure and be packed into filled type Control of Hemorrhage in Laparoscopic Liver door blood
Flow resistance broken belt, filled type Control of Hemorrhage in Laparoscopic Liver door bloodstream blocking band oppress after unidirectionally expanding the whole tied up by which in abdominal cavity 500 or
Part hepatoduodenal ligament, realizes simple, efficient pringle maneuver under peritoneoscope, and does not affect subsequent operation.
For example, switch 402 is disposed with the housing of the infusion pump 400 with Digital Control chip 401, for starting and stopping
Only filled media 300 is filled with to filled type Control of Hemorrhage in Laparoscopic Liver door bloodstream blocking band 100.
It is further preferred that filled type Control of Hemorrhage in Laparoscopic Liver door bloodstream blocking band 100 is connected to band check valve via lock 101
201 connecting tube 200.It is stably connected with so as to be formed.
The present invention had both solved to realize the difficulty of pringle maneuver that is simple, efficient and not affecting subsequent operation under peritoneoscope
Topic, reduces the bleeding of laparoscopic liver resection, ensures the safety of laparoscopic liver resection, reaches Digital Control, simple again
Quick purpose.As long as realizing according to hepatoduodenal ligament Zhou Jing before pringle maneuver, calculate automatically need to fill or
The filled media volume of discharge, is filled automatically or is discharged filled media, automatically control under filled type peritoneoscope by infusion pump
Pringle maneuver band is full or reduces, and realizes quantified controlling pringle maneuver, opening and Xining.
Furthermore, it is necessary to explanation, unless stated otherwise or points out, term " first " otherwise in description, " the
Two ", the description such as " 3rd " is used only for each component in differentiation description, element, step etc., rather than for representing each
Logical relation or ordering relation between component, element, step etc..
