Description
Technical field
This utility model belongs to technical field of surgical instruments, specifically, relates to and a kind of liver week organizes retention device.
Background technology
In surgical operation, during right hepatic lesion excision, usually because position is excessively dark, and cause liver to appear very difficult, not easily observe liver, thus be unfavorable for the carrying out of operation, and the liver existed in prior art appears apparatus, but be by surgical grasping forceps, liver forceps etc., liver is turned up mostly, to appear hepatic lesions position, thus increase the operation technique visual field, but when being turned up liver by these apparatuses, Chang Yin breaks liver or tears tissue and bleeding occurs, and brings misery to patient, increases operation strength and the difficulty of doctor.
Utility model content
For solving above technical problem, the purpose of this utility model is to provide a kind of liver week to organize retention device, simple to operation, liver appears abundant, the simultaneously not easily tissue such as liver injury, improves the efficiency of surgical and the safety of patient, reduces operation strength and difficulty.
This utility model object is achieved in that a kind of liver week organizes retention device, its key is: comprise two sides stop bracket, described in two sides, the inner side edge of stop bracket is hinged by Torque force hinge joint, this stop bracket entirety all bends to circular arc to homonymy, the stop bracket of arc is mainly for being adapted to the outer space shape of liver, be convenient to block liver week tissue, in the outer side edges of stop bracket described in two sides, correspondence is provided with fastening device.
Adopt said structure, open fastening device, two sides stop bracket opens under the elasticity tension effect of Torque force hinge joint, then device is inserted into after below liver, liver is between the stop bracket of two sides, right side stop bracket blocks stomach, colon, nethike embrane Deng Gan undertissue, left side stop bracket blocks the tissues such as diaphram, stop bracket articulated section, two sides is outwards raised, liver is slowly carried away, reach the object appearing liver, the stop bracket of frame-type can be spacing between it stably by liver, appearing of diseased region can not be affected again simultaneously, expand the visual field of surgical operation, improve procedure efficiency and effect, and the relatively existing pawl of this device and pincers etc. have the advantages such as contact area is large, not easily cause and break liver or tear the danger such as tissue, improve the safety of operation.
Above-mentioned fastening device comprises the clamping joint of buckling groove and the setting of corresponding buckling groove, described clamping joint in cylindric, this clamping joint is fixedly installed along the outer side edges of a described stop bracket, described buckling groove is arranged in the outer side edges of stop bracket described in another, the rounded groove in cross section of this buckling groove, when described clamping joint is positioned at described buckling groove, described in two sides, the outer side edges of stop bracket connects and fixes.
Adopt said structure, there are not sharp-pointed parts, only need clamping joint link groove can realize connecting and fixing of stop bracket outer side edges.
Above-mentioned stop bracket comprises outer link, inboard Sinks, the parallel lever be distributed between described outer link and inboard Sinks, the two ends of described lever are fixedly connected with inboard Sinks with described outer link respectively, described lever is convexly curved, it is vertical with the rotating shaft of described Torque force hinge joint that this lever bends face, place, and described buckling groove and clamping joint are separately positioned on two described outer link.
Adopt said structure, the stop bracket of frame-type can be spacing between it stably by liver, appearing of diseased region can not be affected again simultaneously, expand the visual field of surgical operation, improve procedure efficiency and effect, and the relatively existing pawl of this device and pincers etc. have the advantages such as contact area is large, not easily cause and break liver or tear the danger such as tissue, improve the safety of operation.
Above-mentioned outer link upwards arches upward curved, and this outer link and the coplanar setting of described inboard Sinks, the length of described lever shortens from one end of outer link gradually to the other end.
Adopt said structure, device is made to adapt to the shape of liver on the whole, while ensureing liver parking space, reduce device to the extruding of its hetero-organization as far as possible, outer link arches upward curved, when inserting whole device, outer link by appropriate the opening outward of liver peripheral tissue, can be convenient to the insertion of whole device.
Above-mentioned lever is Telescopic supporting rod.
Adopting said structure, when drawing high or shrink longitudinal rod, the active area of whole stop bracket can be increased, to adapt to the liver of different size.
Beneficial effect:
This utility model one organizes retention device in liver week, extruding perienchyma within reason, not easily damage is caused to liver, fully can also appear liver simultaneously, expand the visual field of surgical operation, improve procedure efficiency and effect, improve the safety of operation, and the liver of different size can also be adapted to, improve the scope of application of device.
