Description
Art
This utility model relates to a kind of rotatable type liver surgery postcava root vascular anatomy elastic separating plier, belongs to technical field of medical instruments.
Background technology
Secundum porta hepatis is the position that three hepatic veins (right, in, left) converge with postcava, is the main efferent tract of liver blood flow, and position is relatively deep and is close to diaphram.It is frequently necessary to separate ligation a certain or certain two hepatic vein during liver surgery to block the blood flow flowing out this region liver, there is no the dedicated separation pincers of disengagement chamber portal root blood vessel the most clinically, use large size division of chest disease elastic separating pliers or right angle vascular forceps to replace more.Due to particularity and the importance of caval vein root dissection position, from the point of view of above replacement apparatus is either in terms of the convenience or safety of patient's operation, the most unsatisfactory.Patient uses above replacement fracture caval vein root blood vessel, during the most hepatic venous rear wall, need a hands to take off diaphragm top liver and exert oneself downward tractive to expose secundum porta hepatis, simultaneously, forward lean, another holds the hands of replacement apparatus need to constantly convert the anatomical position holding pincers mode to adapt to postcava root institute separated part, separation efficiency is relatively low and operates uncomfortable, and the most more worry is easily to damage big blood vessel wall under the operation the most smoothly that pincers mode is held in constantly conversion and cause substantial amounts of hemorrhage.Therefore we need a kind of anatomical features according to postcava root badly and design dedicated separation pincers, the operation of patient can be facilitated to improve again the safety of operation.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency in the presence of prior art, and provides that a kind of utilitarian function is prominent, reasonable in design, patient can be facilitated to operate and the anatomical isolation pincers of safely and effectively disengagement chamber portal root blood vessel.
This utility model solves above-mentioned technical problem and be the technical scheme is that
A kind of anatomical isolation pincers being exclusively used in disengagement chamber portal root blood vessel, it is characterised in that: it includes head end separated part, claw beam, attachment means, grip device, connecting rod, rotation wheel and hole flushing part, total length 25cm；
Head end separated part outside and claw beam Joint, the internal steel wire Joint with attachment means, the two ends of connecting rod are hinged with grip device and claw beam respectively, and rotation is taken turns and claw beam Joint, and hole flushing part takes turns Joint with rotating；
Head end separated part is made up of the pincers leaf that two panels is hinged, has, inside pincers leaf, the dentalation mutually coincideing, and clamps leaf the first segment length 2cm, the second segment length 1cm, two sections in 90 degree arc angles, whole separated part and claw beam are 120 degree of arc angles；
Claw beam hollow, is formed by two sections, and there is attachment means the inside, is two stone dead wires inside first paragraph, connects the spring inside separated part and second segment；
Grip device is made up of two parts, affixed with claw beam first paragraph symmetry, is provided with, inside two bracelets, the tooth button matched mutually；
Being provided with rotation wheel on claw beam, its rotation realizes 360 degree of rotations of separated part；
It is provided with hole flushing part on claw beam, communicates with rotation wheel inside and attachment means.
The beneficial effects of the utility model are, compared with prior art, have a following positive effect:
Rotate arranging of wheel to realize head end separated part and rotate at any angle, the vessel anatomy complicated to cater to caval vein root, it is to avoid inconvenience that the twisting of patient's health and wrist is caused and insecurity；
In attachment means spring the stability that can improve operation is set, realized by the opening and closing of grip device that separated part is safer stable opens and Guan Bi；
Hole flushing part communicates inside wheel and attachment means with rotating, in order to realize comprehensive cleaning of the whole elastic separating plier of Post operation；
This utility model utilitarian function highlights, reasonable in design, can make the blood vessel of the disengagement chamber portal root that patient is more convenient and safe in the limited exposure visual field, shorten operating time, improve efficiency；
This utility model processing and manufacturing is easy, with low cost, more suits the needs of surgery of liver clinical treatment.
This utility model really belongs to innovation at aspects such as structure designs, has bigger improvement and innovation than currently used product structure and function aspects, and practical, has preferable market prospect.
