Description
Technical field
This utility model belongs to field of surgical, relates to a kind of knife blade that flap is used of peeling off.
Background technology
Usually need to strip flap in the surgical operation, when particularly burn, face-lifting etc. need be carried out skin grafting, the flap tissue constituted by having certain thickness subcutaneous fat and skin, and function is a flap coverage.At present, when the peeling operation flap when peeling off gap between subcutaneous tissue and the mammary gland body of gland (as), the method for use usually is to use electric knife to cut or use the general surgery blade of single-blade to cut.These peel off mode because there is not the help of specific purpose tool, cause the flap became uneven easily, and peeling rate are slow, and operation is wasted time and energy, inefficiency.Because certain technical requirements is arranged, so the abecedarian is not easy to grasp.Thereby, press for a kind of apparatus that can well peel off flap of research and development in the clinical treatment at present.
The utility model content
The purpose of this utility model is, a kind of knife blade of peeling off flap when surgical operation is provided.
The purpose of this utility model realizes by following technical proposal:
A kind ofly peel off the knife blade that flap is used, comprise cutter head, blade, handle of a knife trepanning, cutter head links to each other with blade, and blade has the handle of a knife trepanning, and wherein cutter head and/or blade at least one worn some protrusions.
Described knife blade, protrusion smooth surface wherein, the top is plane, cambered surface or hemisphere face.Protrusion height is 3mm～10mm, is consistent highly usually; Protrusion quantity is generally 2-12.Be fulcrum with the protrusion top that is positioned at cutter head and/or blade lower surface when peeling off flap, utilize blade cutting skin to peel off, can keep the flap thickness peeled off even.The upper surface of cutter head and/or blade also can have some protrusions, and the flap that can avoid peeling off is adhered to the blade upper surface, improves the speed that flap is peeled off.
Described knife blade, wherein the arrangement mode of a plurality of protrusions is an array.Array refers to the major axis with respect to blade, and protrusion presents horizontal embarking on journey and erects into the arrangement of row.Because the occupy-place of handle of a knife trepanning, protrusion can lack in the position of correspondence, and protrusion also can be arranged by arcual row or column.
Described knife blade, wherein cutter head and blade are that blade extends to the cutter head top from the blade front portion in conplane twolip or single-blade structure.
Described knife blade, wherein twolip converges at the cutter head top end, and there is sword on the cutter head top; The cutter head top is tip, round end, tack, oval head or similar round head.
Described knife blade, wherein blade is plane, handle of a knife trepanning and existing blade holder coupling.
This blade adopts metal material, but sterilizations such as damp and hot sterilization of withstand high temperatures or oxirane.
The beneficial effects of the utility model:
This utility model change lacks the present situation that the flap tissue is peeled off special equipment at present, the cutter head of this knife blade and/or blade have some ganoid protrusions, its critical function is the thickness that guarantees flap, the realization of this function props up skin by operator with this protrusion top, the uniform flap of thickness can be separated easily, and the speed that flap is peeled off can be improved.Twolip design of the present utility model can make operator be positioned at the equal energy of any side handled easily of operative region.
Description of drawings
Fig. 1 is the structural representation of this utility model patent.
Fig. 2 is the sketch map that this utility model cutter head and/or blade lower surface have protrusion.
Fig. 3 is the sketch map that this utility model cutter head and/or blade upper surface and lower surface all have protrusion.
Among the figure: 1 is cutter head, and 2 is blade, and 3 is the handle of a knife trepanning, and 4 is protrusion, and 5 is blade.
The specific embodiment
By the following examples this utility model is further elaborated.
In conjunction with Fig. 1～3, a kind ofly peel off the knife blade that flap is used, comprise cutter head 1, blade 2, handle of a knife trepanning 3, cutter head links to each other with blade, and blade has the handle of a knife trepanning, and wherein cutter head and/or blade at least one worn some protrusions 4.Protrusion smooth surface, top are plane, cambered surface or hemisphere face.Protrusion height is 3mm～10mm, is consistent highly usually; Protrusion quantity is generally 2-12.Be fulcrum with the protrusion top that is positioned at cutter head and/or blade lower surface when peeling off flap, utilize blade cutting skin to peel off, can keep the flap thickness peeled off even.The upper surface of cutter head and/or blade also can have some protrusions (Fig. 3), and the flap that can avoid peeling off is adhered to the blade upper surface, improves the speed that flap is peeled off.The arrangement mode of a plurality of protrusions can be array.Array refers to the major axis with respect to blade, and protrusion presents horizontal embarking on journey and erects into the arrangement of row.Because the occupy-place of handle of a knife trepanning, protrusion can lack in the position of correspondence, and protrusion also can be arranged by arcual row or column.Cutter head and blade are that blade 5 extends to the cutter head top from the blade front portion in conplane twolip or single-blade structure.Wherein twolip converges at the cutter head top end, and there is sword on the cutter head top; The cutter head top is tip, round end, tack, oval head or similar round head.Wherein blade is plane, and handle of a knife trepanning and existing blade holder coupling need not customize blade holder, and be applied widely.This knife blade adopts metal material to make usually, but sterilizations such as damp and hot sterilization of withstand high temperatures or oxirane.
During operation, earlier this knife blade is installed on the existing blade holder.The patient hands handle of a knife, the blade of cutter head portion is inserted the following proper depth of skin, protrusion with cutter head and/or blade lower surface props up skin, continue to insert forward, brandish handle of a knife to a side or to both sides, drive blade, hints on operation is that the protrusion that guarantees cutter head and/or blade lower surface props up skin all the time, can separate the uniform flap of thickness.The petechia can utilize other apparatuses such as electric knife to be stopped blooding.
