Description
Technical field
The present invention relates to medical instruments fields, and in particular to a kind of laparoscope hepatic portal occlusion tool.
Background technique
Hepatotomy operation is often related to the blocking of hepatic portal blood vessel, reduces going out in operation to reduce the blood supply of liver
Blood volume.Traditional hepatotomy operation is carried out in a manner of abdomen by opening, and is generally ligatured with children's rubber urinary catheter to hepatic portal position,
Or carry out clamp with hilus hepatis blocks pincerses, blocking need to reopen a period of time after a certain period of time in case hepatic ischemia/reperfusion injury too long,
Completion, which is repeated several times, with this cuts liver process.In recent years, due to the advantages such as laparoscopic surgery is minimally invasive, post-operative recovery is fast, under laparoscope
Operation on liver is carried out also more and more.But since the notch of laparoscopic surgery is small, traditional hilus hepatis blocks pincerses are difficult to enter
Abdominal cavity, rubber urinary catheter also easily repeatedly can not be tied up and be loosened intraperitoneal.Therefore need one kind can be at present
Tool convenient under laparoscope, that hepatic portal occlusion is effectively performed.
Summary of the invention
The present invention is above-mentioned in order to overcome the shortcomings of, a kind of laparoscope hepatic portal occlusion tool, the laparoscope hepatic portal occlusion tool,
It is easy to operate, the degree of pressure of hepatic portal occlusion can be rapidly adjusted in vitro, repeatedly can be tied up and be loosened, and to Hilar
The tissue damage of position is small, can effective vascular inflow occlusion blood vessel.
A kind of laparoscope hepatic portal occlusion tool provided by the invention, it is made of casing, tie string, snak link, drag hook bar,
Snak link setting passes through the switch control on snak link there are two that can accommodate the duct that tie string passes through in cannula end, snak link
The fixed tie string of spring processed, when drag hook bar use, are inserted into casing, and tie string head end forms lasso, by drag hook bar catch on lasso into
Casing out.Casing is made of hard material, and is hollow tubular structure.
By having the rubber of certain elasticity to be made, a diameter of 0.5cm, head end forms circular the tie string
Lasso, lasso are made of silk thread, diameter 0.05cm, and tie string tail end has rope pendant.
The head end of the drag hook bar forms back hook, and the buckle above back hook rotates upwardly and downwardly openable or closing back hook,
The tail end of drag hook bar forms annulus.
Tool design of the invention is reasonable, and structure is simple, easy to operate, can rapidly adjust the pressure of hepatic portal occlusion in vitro
Range degree repeatedly can be tied up or be loosened, and small to the tissue damage at hepatic portal position, can effective and safe ground vascular inflow occlusion blood
Pipe.
Specifically, drag hook bar of the invention is more very thin than conventional laparoscopic surgical clamp figure, back hook can catch on and tie up
The lasso of rope, annulus can be entangled to pull operation, therefore can be not take up excessive casing space and can complete to catch on finger
And draw the function of tie string disengaging casing.Further, since casing space is not occupied excessively by drag hook bar, in tie string design
It is thicker than the laparoscope bounding wire of certain patents, and be made of the rubber with certain elasticity, closer traditional catheter,
Therefore small to the tissue damage at hepatic portal position, it is not susceptible to incised injury, too loose or tension will not be strangled.Further, due to bundle
Jag is thicker, keeps out between casing and hepatic portal tissue, therefore complete hard material can be used without damage hepatic portal in casing
Tissue is also not susceptible to the accident that casing folding is turned round.Cannula end forms snak link, and there are two can accommodate tie string to pass through for snak link
Duct, opening or closing for duct can loosen or fix tie string, press its switch and can rapidly realize and loosen or fix
Tie string, it is easy to operate, it is fixed.
Detailed description of the invention

Specific embodiment
The present invention is further described in conjunction with the accompanying drawings and embodiments.
Embodiment 1
Referring to figs. 1 to 4, a kind of laparoscope hepatic portal occlusion tool, by casing 1, tie string 2, snak link 3,4 groups of drag hook bar
At the setting of snak link 3 is in 1 tail end of casing, and snak link 3 is there are two that can accommodate the duct that tie string 2 passes through, by snak link 3
Switch 9 control the fixed tie string 2 of spring 10, spring 10 compresses if pinning switch 9, duct unlatching (as shown in Figure 3, Figure 4),
Tie string 2 is unclamped, can be twitched up and down, then spring 10 pops up trip switch 9, and (as shown in Figure 1) is closed in duct, and tie string 2 is fixed.
Casing 1 is inserted into when drag hook bar 4 uses, 2 head end of tie string forms lasso 5, catches on lasso 5 by drag hook bar 4 and passes in and out casing 1.
Casing 1 is made of hard material, and is hollow tubular structure.
For tie string 2 by having the rubber of certain elasticity to be made, a diameter of 0.5cm, head end forms circular lasso
5, lasso 5 is made of silk thread, diameter 0.05cm, and 2 tail end of tie string has a rope to fall 6, and tie string 2 can be prevented from snak link 3
Duct deviate from (as shown in Figure 1).
The head end of the drag hook bar 4 forms back hook 7, and the button 11 of 7 top of back hook is rotated upwardly and downwardly openable or closed
The tail end of back hook 7, drag hook bar 4 forms annulus 8.Back hook 7 can catch on the lasso 5 of tie string 2, can draw tie string 2 forward or to
After move, and be not easy (as shown in Figure 1), annulus 8 can be entangled with finger convenient for drawing operation.
Embodiment 2
When laparoscopic surgery, several handle holes can be generally held on the body of patient, insertion Trocar pipe, is used on handle hole
To be put into surgical instrument.For the present invention in use, casing 1 is first inserted into Trocar pipe, pressing snak link switch 9 opens duct,
The duct (referring to Fig. 3) that the head end of tie string 2 is passed through to snak link 3 enters abdominal cavity by casing 1.Tie string 2 is from needs
Around (this process can be with surgical clamp in other Trocar pipe auxiliary operations) below the hepatic portal blood vessel of blocking.Drag hook bar 4 passes through
Another duct of snak link 3 enters abdominal cavity, and the lasso 5 (as shown in Figure 1) of 2 head end of tie string is caught on the back hook 7 of drag hook bar,
Another duct that traction tie string 2 wears back snak link 3 returns to external (as shown in Figure 2).In vitro, by the head end of tie string 2
It being pulled outwardly with tail end, while casing 1 being pushed away to internal direction, casing 1 and tie string 2 just entangle and tighten blood vessel 12 at this time,
Finally unclamp again the switch 9 of snak link, the both ends (as shown in Figure 2) of fixed tie string 2.If you need to blood vessel of loosening, bullet need to be only pinned
It loosens after the switch 9 of spring button tie string 2.
