Description
Technical field
The invention belongs to the technical field of anatomical Hepatic segmentectomy instrument, in specially a kind of liver vascular puncture block pincers and
Its application method.
Background technology
Anatomical hepatic segmental resection is the standard art formula of row liver cancer radical excision.Because liver cancer is many less when
Infiltrated with portal vein or to Intrahepatic metastasis, anatomical excision is carried out to lotus knurl hepatic segments from the angle requirement of radical cure；On the other hand,
Majority of cases from the point of view of liver function, is not suitable for making the big of lobe of the liver or half liver etc because merging chronic hepatitis and hepatic sclerosis
Scope is cut off, it is contemplated that also to retain liver function while radical cure to tumour, such a art formula is established after weighing the advantages and disadvantages；Closely
The year progress of hepatotomy technology is mainly based upon the progress that method of losing blood is reduced in anatomical Hepatic segmentectomy and art and obtained.
Intraoperative ultrasound guiding Xiamen venipuncture injection developer determines that hepatic segments scope is to implement Hepatic segmentectomy " goldstandard " method.Reason
According to each hepatic segments to be cut off it is under independent one or several portal veins and arteria hepatica blood supply, intraoperative ultrasound orientation direction by being
With lancet puncture hepatic pedicle blood vessel, the methylene blue of several milliliters of injection, hepatic segments surface is in a big colour attaching area, shows the boundary of liver section
What line, the detachment liver parenchyma after row in-degree sequence at porta hepatis, ligation blood vessel and bile duct cut off so as to reach anatomical
Purpose.
The key point of this technology of successful implementation be intraoperative ultrasound identification hepatic segments hepatic pedicle blood vessel after, carry out accurately puncture,
Dyeing and hepatic segments enter effective control of hepatic blood flow.
As described above, current anatomical Hepatic segmentectomy is hepatic pedicle intravascular injection U.S. of positioning hepatic segments under ultrasound guidance mostly
Orchid makes liver surface be cut off after developing the color, and the hepatic blood flow that enters of hepatic segments often cannot be controlled effectively, be caused in detachment liver
Methylene blue fade is so as to can not correctly define the line of demarcation between hepatic segments cut off and normal hepatic segments during essence, thus hardly possible
To accomplish the accurate excision of hepatic segments；In addition, hepatic segments surface of a wound bleeding generally requires to block porta hepatis could effectively during excision
Control, and block and enter the ischemical reperfusion injury that hepatic blood flow frequently can lead to liver entirely, the patient heavier to hepatic sclerosis is postoperative
Liver function recovery is very unfavorable.Therefore, preferable mode be puncture dyeing while or later carry out hepatic segments enter hepatic blood flow
Effective control, this accurate excision to hepatic segments is vital.
The method that the hepatic segments of selectivity control at present enters hepatic blood flow is very limited, and minority report is dissected step by step from porta hepatis to be chased after
Track separation hepatic segments hepatic pedicle carries out ligation processing, and this method can be realized to left liver hepatic segments hepatic pedicle (to be entered because left side hepatic pedicle
Gan Qian branches), and to often wound is larger, blood loss is more, technical difficulty is high in right liver hepatic pedicle separation process and takes very much (right
Side hepatic pedicle is more in Gan Nei branches)；Thus this method is difficult to popularize.In consideration of it, how selectivity to hepatic segments hepatic pedicle (especially
It is right side) effective control for entering hepatic blood flow is also accurate surgery of liver major issue urgently to be resolved hurrily instantly.
The content of the invention
Pincers and application method are blocked it is an object of the invention to provide vascular puncture in a kind of liver, it is intended to anatomical hepatic segments
Resection operation flow is optimized.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：
Vascular puncture blocks pincers in a kind of liver, using crosspoint rotating shaft screw as boundary, point forearm and postbrachium two parts, postbrachium
Finger ring set and latch bar are respectively provided with the two-arm of left and right, finger ring set is arranged on postbrachium, and the latch bar on the postbrachium of left and right is complementary in opposite directions,
Blocked to be engaged, latch bar is hollow design in rotating shaft screw, left and right forearm, is provided with passage, in left and right forearm
Rear end is equipped with mounting hole, is connected with passage, and lateral aperture is provided with positioned at left forearm front end side, lateral aperture and left forearm it is logical
Road is connected, and left and right forearm front end is equipped with tip, and tip is semicircle cone, and both sides tip is closed on cone, right forearm
Tip in be provided with passage, and in its summit side provided with portalling, it is sophisticated in passage and right forearm in passage and go out
Hole is connected, and in left and right, forearm leading inside is respectively equipped with satinsky's clamp tooth and groove, and satinsky's clamp tooth is intermeshed with groove,
Forearm is closed into the slightly larger round estrade of the small rear end diameter of point diameter, is easy to pierce through blood vessel.
Further, mounting hole site is in the outside of left and right forearm rear end, and mounting hole is interior provided with installation screw thread, the peace of left forearm
Fill Kong Shangke connections and LED/light source or attractor are installed, syringe can be accessed by connecting tube on the mounting hole of right forearm, also may be used
High-frequency electrical condenser is installed in connection；Length scale mark is equipped with the forearm of left and right, mark spacing is 1cm, is easy to hold in art and wears
Pierce depth.
Further, on the inside of the leading portion of left and right forearm on occlusal surface, bar shaped not damaged of the left forearm provided with two longitudinal directions
Tooth is clamped, right forearm is provided with two grooves matched with satinsky's clamp tooth, and satinsky's clamp tooth is just embedding when left and right forearm is engaged
Together in groove.
Further, left and right forearm stops this segment distance near rear end rotating shaft screw to front end satinsky's clamp tooth section start
Carry out high-temperature insulation processing.
Further, postbrachium rear end, which is provided with hole clipping, hole clipping, is provided with rubber layer, and finger ring set front end is provided with installation axle, installs
