The specific embodiment
In order to make content of the present utility model more clear and understandable, below in conjunction with specific embodiments and the drawings, content of the present utility model is described in detail.
This utility model filled type Control of Hemorrhage in Laparoscopic Liver door bloodstream blocking band is the flat soft band of a unidirectional expansion, be preferably the flat soft band of medical silica-gel material, when use by outside Liu Yu abdominal cavity, its one end, all the other major parts are placed into intraperitoneal, around all or part of hepatoduodenal ligament, tentatively tie up filled media (air, CO with one-way ventilation control device
2or normal saline) rear its inside unidirectional expansion, thus closely tie up all or part of hepatoduodenal ligament, in blocking-up hepatoduodenal ligament, Hepatic artery, portal venous flow etc., realize vascular inflow occlusion blood flow under peritoneoscope.
Below in conjunction with accompanying drawing, specific embodiment is described.
Referring to figs. 1 to Fig. 6, comprise strip tubular body 100 according to the filled type Control of Hemorrhage in Laparoscopic Liver door bloodstream blocking band of this utility model preferred embodiment; Wherein strip tubular body 100 first end 101 is in the longitudinal direction opened, and strip tubular body 100 the second end 102 in the longitudinal direction seals, thereby forms the inner space of the opening with first end 101 places.
Strip tubular body 100 has and is filled with filled media to inner space by the opening at first end 101 places (for example, filled media includes but not limited to air, CO
2or normal saline) time full state.
And, with the perpendicular cross section of the length direction of strip tubular body 100 on, the wall thickness of the first side 10 of strip tubular body 100 is less than the wall thickness of the second side 20 of strip tubular body 100; Under full state, the expansion rate of the wall of the first side 10 is greater than the expansion rate of the wall of the second side 20 thus.
Wherein, preferably, described strip tubular body 100 is flexible main body.
Preferably, the material of described strip tubular body 100 is medical silica-gel.
Preferably, the wall thickness that makes the second side 20 of strip tubular body 100 is at least five times of wall thickness of the first side 10 of strip tubular body 100, makes filled type Control of Hemorrhage in Laparoscopic Liver door bloodstream blocking band substantially show as unidirectional expansion under full state.
Further preferably, the wall thickness that makes the second side 20 of strip tubular body 100 is at least ten times of wall thickness of the first side 10 of strip tubular body 100, now better bonding to dilatancy.
On the other hand, preferably, for the selection of the wall thickness of the first side 10 and the wall thickness of the second side 20, can be concrete thickness limited ratio, is at least five times of expansion rate of the wall of the second side 20 but can make the expansion rate of the wall of the first side 10; More preferably, can make the expansion rate of the wall of the first side 10 is at least ten times of expansion rate of the wall of the second side 20.
And, further, as shown in Figure 5 and Figure 6, preferably, also comprise according to the filled type Control of Hemorrhage in Laparoscopic Liver door bloodstream blocking band of this utility model preferred embodiment: the connection tube 200 being connected with the opening at first end 101 places of described strip tubular body 100.Come to be conveniently filled with filled media to inner air by connecting a connection tube 200.
And preferably, described connection tube 200 is connected to the opening with first end 101 places of described strip tubular body 100 removably, like this can more convenient operation when concrete.
Like this, as shown in Figure 5 and Figure 6, when filled type Control of Hemorrhage in Laparoscopic Liver door bloodstream blocking band of the present utility model uses, need only and stay connection tube 200 filled medias outside abdominal cavity at it, its one end (first end of opening) stayed outside abdominal cavity, all the other major parts are placed into intraperitoneal, around all or part of hepatoduodenal ligament; Just can make it be positioned over intraperitoneal and tentatively to tie up the part of all or part of hepatoduodenal ligament B full; Wherein, thin-walled side (the first side 10) is towards hepatic portal blood flow, inside unidirectional expansion, the blood flow of Hepatic artery C, portal vein D and common bile duct E in blocking-up hepatoduodenal ligament; Realize the effect of pringle maneuver.Aforesaid operations is simple, quick, and barrier effect is thorough.This utility model filled type Control of Hemorrhage in Laparoscopic Liver door bloodstream blocking band is a soft band (flexible main body) in addition, does not take an operation path and certain intraperitoneal space, does not affect follow-up operation technique.This utility model has overcome existing various simple and easy Porta hepatis blocker and under peritoneoscope, has been not easy operation, and it is firm not that hepatoduodenal ligament is tied up knotting, clamp, blocks thoroughly, may affect the shortcomings such as subsequent operation.
Can find out, filled type Control of Hemorrhage in Laparoscopic Liver door bloodstream blocking band of the present utility model is effectively tied up hepatoduodenal ligament by unidirectional expansion energy, and vascular inflow occlusion blood flow is tied up reliably, is difficult for slippage, the big or small scalable of the relevant position of tying up and formation.
Manufacture for above-mentioned filled type Control of Hemorrhage in Laparoscopic Liver door bloodstream blocking band, can choose the medical silica-gel nontoxic to human body, by Design of Dies, process with injection machine.Blocking-up band is realized unidirectional expansion by the flat soft uneven thickness (outside is thick, and inner edge is thin) with wall of medical silica-gel.The length of blocking-up band, width and connection tube diameter, the connection tube length in cross section can be any appropriate size, or can manufacture the bloodstream blocking band of width, connection tube diameter and the connection tube length with different length, cross section, to can adopt for concrete patient the bloodstream blocking band of different size.
In addition, it should be noted that, unless stated otherwise or point out, otherwise the descriptions such as term " first " in description, " second ", " the 3rd " are only for distinguishing each assembly, element, step of description etc., rather than for representing logical relation or the ordering relation etc. between each assembly, element, step.
