Description
Technical field
The utility model relates to medical instruments field, dress is established in tunnel after more specifically to a kind of liver that can be monitored
It sets.
Background technique
Hepatocellular carcinoma is one of most common malignant tumour in world wide, and disease incidence and the death rate occupy malignant tumour
Forefront.China is liver cancer big country, and annual whole world new cases and death are to occur in China there are about half, improves liver cancer
Diagnosis and treatment level be of great significance.Currently, liver cancer is most effective and is uniquely possible to the treatment method cured still
It is hepatectomy.Carry out the excision of right half liver safely in open surgery, tunnel is around band technology after the liver created with Belghiti
(lifting technology around liver) is most useful, and the domestic refined window professor of Peng introduces and improved.Tunnel (is mentioned around liver around band technology after liver
Pull technology) the special anatomical features based on liver post gap.Tunnel refers to one between liver back segment inferior caval vein and liver parenchyma after liver
A relatively small number of potentiality gap of blood vessel, suitable for reading is vena hepatica filling nest, and lower mouth is caudate lobe rear, inferior caval vein front after liver
Crack, gap width averagely about 1cm, upper and lower diameter about 7cm.
Using tunnel after liver around band technology (i.e. around liver lift technology) key be to establish liver after tunnel, current main foundation
Belghiti is created, the domestic refined window professor of Peng introduces the standard diameter path method illustrated and establishes tunnel after liver.Using tunnel after liver around
Band technology (i.e. around liver lift technology), the liver that can rive under anterior approach center are split, thus exposure Oral Ganduqing liquior, right hepatic veins again from
It is disconnected, also avoid damage to inferior caval vein；Keep liver section minimum, most thin simultaneously, and controllable section bleeding；In addition avoid extruding liver swollen
Tumor.At present after establishing liver in tunneling process, mainly with big curved hemostat along the avascular area cephalad in liver post gap center
Vein lacuna passivity promotes, and joins forces foundation under finger guidance.This method is mainly carried out according to the experience of operator, is had
Certain " blindness ", has damage the possibility of Oral Ganduqing liquior.Oral Ganduqing liquior is damaged to reduce, many scholars improve standard pathway side
Method, but improve and substantially only shorten standard pathway, it is last or to be penetrated through using big curved hemostat, with very big " blind
Mesh ", can not tunnel is established after real-time monitoring liver process, there are biggish risks, it is easy to damage Oral Ganduqing liquior, cause
Operative failure.
In addition, tunnel after liver is established under laparoscope to be guided with finger, just in case damage Oral Ganduqing liquior, not only because of nothing
Method oppresses easily big bleeding with hand, and high pressure pneumoperitoneum is easy to form aeroembolism.Therefore the big curved hemostat of above-mentioned application penetrates through standard
The method of pathway is not appropriate for establishing tunnel after liver under laparoscope.Some scholars are attempted under laparoscope, using golden finger or nose
Stomach tube establishes tunnel after liver, but this method is only it is observed that liver post gap caudal initial part, can not observe among liver post gap
Portion and cephalic region, tunnel still has certain " blindness " after liver is directly established in guidance.
Utility model content
For existing tunneling technique of establishing after liver there are larger blindness, the problems such as risk is high, the utility model to be solved
Device is established in tunnel after certainly the technical issues of is to provide the liver that one kind can monitor, and tunnel is established after which can be monitored in real time liver
Process, considerably reduce the blindness operated in tunneling process after establishing liver, effectively increase the success rate of operation, simultaneously
Improve the accuracy of operation, the safety of effective guarantee operation.The utility model is applicable not only to human body, is also applied for other
Animal, comprising: partially there is the experimental animal of tunnel structure after liver similar with the mankind, such as dog.
The technical issues of to solve the utility model, the utility model adopts the following technical solutions:
Device is established in tunnel after a kind of liver monitored, and it includes that operation is established in tunnel that device is established in tunnel after the liver
Bar, in vivo fixed guidance device and external secured adjusted device, it includes monitoring device and tissue that operating stick is established in the tunnel
Dissection device, the monitoring device are used for the foundation in tunnel after real-time monitoring liver, and the anatomic tissue device is used for liver
Post gap carries out separation dissection, establishes tunnel after liver, and the internal fixed guidance device passes through the first restraint device and tunnel
Operating stick connection is established, fixed guidance device is used to fix in vivo, guide tunnel establishes operating stick, so that tunnel is established operating stick and exists
It is consistent with tunnel center longitudinal axis after liver in tunnel establishment procedure after liver；The external secured adjusted device is about got one's things ready by second
It sets and is connect with fixed guidance device in vivo, external secured adjusted device is described for adjusting and fixing guidance device in fixed body
External secured adjusted device establish operating stick by adjusting internal fixed guidance device to control tunnel so that behaviour is established in tunnel
Make bar and advance along tunnel after liver from the standard pathway direction of caudal cephalad, establishes tunnel after liver.Tunnel is built after the liver
Vertical device may be implemented after establishing liver in tunneling process, and monitoring device is protruded into inside liver post gap, after real-time monitoring liver between
The anatomical isolation of gap tissue considerably reduces the blindness operated in tunneling process after establishing liver, effectively increases operation
Success rate, while guaranteeing that the direction of advance of operating stick is established in tunnel using fixed guidance device and external secured adjusted device in vivo
It is consistent with tunnel center longitudinal axis after liver, avoid offset direction, it is ensured that tunnel is created as power after liver, while it is short quiet to avoid damage to liver
Arteries and veins, it is ensured that safety is established in tunnel after liver.
