Description
Technical field
The present invention relates to medical instruments field, relate in particular to a kind of operating Minimally Invasive Surgery cutter that is used for.
Background technology
Minimally Invasive Surgery is little because of wound, light pain, recovery receive patient's welcome soon.But because the restriction of equipment and condition, operation has very high requirement to the doctor.In the prior art, the scalpel that surgical clinical is used has small needle knife and general surgery cutter usually, and the small needle knife cutter head is narrow; The thin insufficient strength of cutter hub; Handle of a knife is short and small violin type in addition, is unfavorable for that cutter head regulates direction, in addition cutting and separating and do not reach therapeutic purposes; The general surgery cutter blade is roomy, and is big to normal tissue injury, is not suitable for doing Minimally Invasive Surgery.Therefore; How to design high with a kind of order of accuarcy, can not cut off the meat fiber tissue, to pathological tissues in the body cut out wound little, go out insufficiency of blood, no large tracts of land wound contacts with air with intraluminal tissue; Reduce and infect probability, become the direction that those of ordinary skills make great efforts.
Summary of the invention
The present invention provides a kind of operating Minimally Invasive Surgery cutter that is used for, and this Minimally Invasive Surgery cutter order of accuarcy is high, can improve therapeutic effect and can reduce tissue injury.
For achieving the above object, the technical scheme that the present invention adopts is: a kind ofly be used for operating Minimally Invasive Surgery cutter, comprise: blade, handle of a knife and knife bar; This knife bar one end has groove, and the said handle of a knife cross section that is connected and composed by the first bar shaped portion and the second bar shaped portion is a rectangle, and the said first bar shaped portion other end is fixed in the groove of said knife bar; The height of the first bar shaped portion is higher than the height of the second bar shaped portion, and the height of said blade is higher than the height of the second bar shaped portion, this second bar shaped portion and between the blade at its two ends and the first bar shaped portion, form a groove area; Said blade is welded on the forward side of the said second bar shaped portion; The bottom face of the blade bottom face and the second bar shaped portion is positioned at same plane and has the bar weld zone between the two, has three Welding Areas between the upper surface of the upper surface of said blade and the second bar shaped portion; The length direction angle of the knife edge of said blade and blade is 79 ~ 81 °, and blade top has a chamfering inclined-plane.
Further improved technical scheme is following in the technique scheme:
As preferably, said knife bar cross section is circular.
As preferably, the diameter of said knife bar is 1.5 ~ 1.7 millimeters.
As preferably, the rear portion that is positioned at said knife bar is provided with the through hole of two parallel arrangements.
As preferably, has an inclined-plane connecting portion between the said first bar shaped portion and the second bar shaped portion.
As preferably, angle is 30 ° between the said inclined-plane connecting portion and the first bar shaped portion and the second bar shaped portion.
Because the technique scheme utilization, the present invention compared with prior art has advantage:
1, the length direction angle of the blade of Minimally Invasive Surgery cutter blade of the present invention and blade is 79 ~ 81 °, has improved Minimally Invasive Surgery cutter accuracy greatly; Blade top has a chamfering inclined-plane, and when the push broach groove went out cutter and cuts and organizes, blade upper design one chamfering inclined-plane played guide effect, greatly reduces the resistance that the blade top edge brings because of friction, thereby has reduced the edge damage probability at the Minimally Invasive Surgery cutter.
2, because the blade of Minimally Invasive Surgery cutter of the present invention is thin; Fix through Welding Area between the blade upper surface and the second bar shaped portion upper surface; And the blade lower surface and the second bar shaped subordinate end face are fixed through the bar weld zone; Both effectively avoided melting welding, and can prevent again to snap and embrittlement between the blade and the second bar shaped portion, thereby guarantee the precision of scalpel and prolonged the Minimally Invasive Surgery cutter life-span.
3, the present invention is used for operating Minimally Invasive Surgery cutter, and its order of accuarcy is high, can not cut off the meat fiber tissue; It is little that pathological tissues in the body is cut out wound, goes out insufficiency of blood, no large tracts of land wound contacts with air with intraluminal tissue, reduces and infect probability; Need not to sew up; Shorten operating time greatly, postoperative pain is light, recovery is fast, cicatrix is trickle or do not have cicatrix, is ideal surgical apparatus.
4, Minimally Invasive Surgery cutter knife bar of the present invention is circular, helps Minimally Invasive Surgery cutter 360 ° of rotary manipulations in the scalpel assembly, has improved the working place of operation.
