Abstract
The invention discloses a hepatic blood vessel clipping device which comprises a hollow sleeve, wherein a hollow trocar penetrates through the inside of the hollow pipe; the tip end of the hollow trocar extends out of the hollow sleeve; the hollow trocar sleeves a probe for detecting a blood vessel in the liver; when the blood vessel to be detected is detected, the hollow trocar and the probe are removed out of the hollow sleeve; a blood vessel clip penetrates through the hollow sleeve, and the clipping part of the blood vessel clip gets close to the blood vessel to be detected and can slip the blood vessel to be detected; the clip application part of the blood vessel clip extends out of the end, away from the blood vessel to be detected, of the hollow sleeve. By the cooperation with training of an ultrasonic and 1:1 3D printing in-vitro model, the device can precisely go to a part which probably bleeds and clip the part, so that ischemia and discoloring of the hepatic segment of a tumor region can be directly caused, and a precise resection line is formed; therefore, the hepatic lesion can be quickly and safely cut off, and a new era for the hepatic surgery is opened.
Description
Technical field
The present invention relates to a kind of liver vessel folder closes device.
Background technology
Liver is maximum digestive gland in digestion, and adult human liver averagely weighs between 1～2.5 kilogram, exercises
Multiple indispensable important physiological function.Hepatectomy in surgery of liver is basic and requisite operation technique, by
Very abundant in the blood supply of liver, containing portal vein, Hepatic artery, three sets of vascular systems of hepatic vein, only it is just to reach into hepatic blood flow
Arrive 1400ml/min, and liver has been opaque bulk (length and width of liver, thick about 25.8cm, 15.2cm, 5.8cm), reality
Matter internal organs, internal blood vessel complexity is it is impossible to effectively find rapidly trunk by general straightforward procedure to carry out hemostasis by ligation, institute
It is frequently accompanied by bleeding profusely with hepatectomy.Massive hemorrhage is also to lead to post-operative complication and main causes of death.Therefore, liver blood
Stream interrupter technique is increasingly widely applied.Due to the blood vessel of liver deep in liver parenchyma it is impossible to ligature easily, so
Current hepatic vascular exclusion mode is not the blood vessel being directed to tumor vicinity in liver, but the supply blood outside liver
Pipe is controlled, for example porta hepatis, secundum porta hepatis, suspension scheme etc..And, block and can draw into hepatic blood flow row hepatectomy
Play normal liver tissue and suffer from ischemical reperfusion injury, especially to merging patient with liver cirrhosis, initiation liver failure can be increased even
Dead possible.Therefore, how to control intraoperative hemorrhage and reduce the infringement to liver function for the ischemia-reperfusion, always surgery of liver
In great difficult problem.
With the development in epoch, from world's the first pringle method hepatic portal occlusion, to half liver in-degree sequence, selectivity
Region in-degree sequence method, total hepatic vascular exclusion, develop into loop around in-degree sequence from continuous blocking-up now
Block or carry out before hepatic portal occlusion Ischemic reperfusion blocking-up, selectivity total hepatic vascular exclusion technology/holding postcava unobstructed
The technology such as omni-liver blood stream interruption.
It is now recognized that preferable liver blood method of flow control should possess following condition: (1) thoroughly blocking blood flow.Energy
Block enter liver and the blood flow flow going out liver enough, make surgical field of view clear；(2) selectivity is good.Can selective exclusion intend being removed
Hepatic segments, few to residual liver function influence；(3) few on systemic hemodynamic impact；(4) simple to operate, safe and easy to learn.But
Bleeding in hepatectomy and ischemia-reperfusion lead to damage, liver failure problem to still fail to solve well.
Prior art is not directed to the blood vessel of the possible bleeding of tumor section, but from being far apart, easy to handle
Carry out the blocking-up (also corresponding to folder to close) of liver blood flow outside liver.Unnecessary hepatic ischemia reperfusion so can be caused to damage
Wound, thus cause clinically fatal liver failure.And bloodstream blocking/the folder of this indirect type closes scheme operating time
Long, the anesthesia that patient suffers from, bleeding equivalent damage are bigger, expend more.
Content of the invention
The technical problem to be solved is, not enough for prior art, provides a kind of liver vessel folder to close device.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is: a kind of liver vessel folder closes device, including
Hollow bushing；Hollow bushing pin passes through from described hollow bushing, and described hollow bushing needle tip stretches out described hollow bushing；
Described hollow bushing needle guard is in the probe for detecting blood vessel in liver；When detecting blood vessel to be detected, described hollow
The trocar and described probe remove described hollow bushing, and a blood vessel applicator passes through described hollow bushing, and described blood vessel is applied
The retained part of binder is close and can clamp described blood vessel to be detected；The clamp part of described blood vessel applicator stretches out described sky
Heart sleeve pipe is away from one end of described blood vessel to be detected.
Within 3mm, so design can reach effective puncture liver to described hollow bushing internal diameter, forms operation logical
Road, and there is not big bleeding.
Described hollow bushing pin is cylindrical shape, and the tip of cylindrical shape has a slope or taper seat.Using circle
The hard material of column, can effectively penetrate liver, result in the liver of hardening including a variety of causes, and indeformable, prevent
It is punctured to the position of mistake.Most advanced and sophisticated slope or taper seat can effectively pierce liver, form subsequently required operation
Duct.
Compared with prior art, the had the beneficial effect that assembly of the invention of the present invention, cooperation is ultrasonic and 1:1
3d prints external model training, can accurately attack the position of possible bleeding directly, carries out pressing from both sides closed operation, can directly result in tumor
The hepatic segments ischemia variable color in region, forms and accurately excises line, thus the pathological changes that hepatectomize that can be quick, safe, open liver
New era of surgery.
Brief description
Fig. 1 is embodiment of the present invention positioning unit structural representation；
Fig. 2 is embodiment of the present invention grip unit structural representation.
Specific embodiment
As shown in figure 1, embodiment of the present invention positioning unit includes hollow bushing 1；Hollow bushing pin 2 is from described hollow bushing
Pass through in 1, and described hollow bushing 1 is stretched out at described hollow bushing pin 2 tip；Described hollow bushing pin 2 is enclosed within for detecting liver
On the probe 3 of dirty interior blood vessel；When detecting blood vessel 6 to be detected, described hollow bushing pin 2 and described probe 3 removal are described
Hollow bushing 1, the blood vessel applicator 4 of grip unit passes through described hollow bushing 1, and the retained part of described blood vessel applicator 4
Near and described blood vessel to be detected can be clamped；The clamp part of described blood vessel applicator 4 stretches out described hollow bushing 1 away from institute
State one end of blood vessel to be detected.
Blood vessel applicator can adopt titanium clamp pincers.
During use, hollow bushing pin and probe (such as ultrasonic probe) insertion hollow bushing puncture and enter liver parenchyma,
Probe can detect the various pipeline configurations in liver parenchyma, prints solid transparent model in the 3d of external ultrasound probe and 1:1
The lower auxiliary of three reorientations auxiliary under, the blood vessel needing clamping can be navigated to, then remove the trocar and probe, titanium is pressed from both sides
Pincers stretch into from hollow bushing, under the auxiliary of external ultrasound probe, clamp the blood vessel needing clamping.
Puncture road the shortest can be selected by the transparent liver of one to one printing and vascularity model during use
Footpath, accurately punctures, folder closes blood vessel in liver, substantially reduces amount of bleeding, greatly reduce operating difficulty, when greatly shortening operation
Between.
