Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is elaborated.
As Figure 1-Figure 5, a kind of breast malignant tumor body cutting circular operation knife, comprises handle of a knife, described handle of a knife is inlaid with cutter hub, described cutter hub is annular cutter hub, and the lower end of described annular cutter hub is provided with blade, the surface of described handle of a knife be provided with for point hold hold groove.The cylinder of described handle of a knife to be cross section can be regular polygon, and described in hold groove and be equipped with on the side of described regular polygon cylinder.Described annular cutter hub cross section is circular or oval.The outer surface of described annular cutter hub is also carved with rule groove, is convenient to doctor and determines penetraction depth easily in use.The blade of described annular cutter hub is obtained by medical steel metal, and described handle of a knife is obtained by medical rigid plastics.The internal diameter of described annular cutter hub is 3-8cm, specifically can determine the diameter of annular cutter hub according to practical situation.
As shown in Figure 6, as preferred implementation of the present utility model, for being flexibly connected between handle of a knife described in the utility model and annular cutter hub, in described handle of a knife, be provided with annular hollow structure, described annular hollow structure internal diameter be not less than the external diameter of annular cutter hub; Described handle of a knife is cross section is orthohexagonal column structure, the cylinder plane at place, described orthohexagonal every bar limit offers for point hold hold groove, described holding on groove offers through hole, described through hole is perpendicular to the plane in its regular hexagon sideline, place, and extend in annular hollow structure, described through hole also mates clamp column, the back-moving spring be arranged in described clamp column being also provided with stopping means in described through hole and mating with stopping means; Described annular cutter hub and described cutter handle combining part are provided with the cutter hub through hole mated with described through hole, described clamp column is the different cylinder of two sections of diameters, described diameter small end stretches in through hole, the diameter of described cutter hub through hole is not less than the diameter of clamp column diameter small end and is not more than the diameter of the large end of clamp column diameter, and the diameter of the large end of described clamp column is not more than the diameter of through hole.This embodiment, can coordinate the cutter hub of multiple different-diameter to use by a handle of a knife simultaneously.
When needs use this utility model, select the circular operation knife of suitable diameter size, during as row mammary gland cancerous protuberance thing extensive lumpectomy, swollen thing diameter is 1cm, and be circular substantially, according to relevant professional knowledge, this makes Professional knowledge belong to this medical domain known technology, do not belong to protection part of the present utility model, selection diameter is the circular ring-shaped scalpel of 4-5cm, swollen thing is placed in home position, hand-held handle of a knife, careful rotation cuts lump surrounding tissue to pectoralis major fascia surface, remove circular operation knife, thing will be swollen from pectoralis major skin cut, respective handling can be done further as requested.
By selecting the size of suitable size, be placed in the swollen thing surface of an incision skin, by clockwise and counterclockwise low-angle circumgyration incision repeatedly, can by the complete separation of normal structure of swollen thing and around certain limit, basal surface can be removed complete for the normal structure of swollen thing and around certain limit from patient body with apparatuses such as Electric scalpels, have structure simple, save time, safe, the easy to use and advantage conveniently promoted the use of.This circular operation knife is not only positive circle, also has oval, as minor axis be 4cm, major diameter is 6cm, or minor axis be 5cm, major diameter be 7cm etc. all likely because lump has oval, have orbicular.Orbicular internal diameter diameter be 3cm-8cm not etc.Oval minor axis is 3cm-6cm, major diameter be 4cm-8cm not etc.
