Description
Technical field
The present invention relates to medical instruments field, particularly relate to a kind of for operating minimally-invasive scalpel.
Background technology
Minimally Invasive Surgery is subject to the welcome of patient because wound is little, pain light, it is fast to recover.But due to the restriction of equipment and condition, performing the operation has very high requirement to doctor.In prior art, the scalpel of surgical clinical application has small needle knife and coventional scalpel usually, and small needle knife cutter head is narrow, the thin insufficient strength of cutter hub, in addition handle of a knife is short and small violin-shaped, is unfavorable for that cutter head regulates direction, cutting and separating and do not reach therapeutic purposes in addition; General surgery cutter blade is roomy, and normal tissue damage is large, is not suitable for doing Minimally Invasive Surgery.Therefore, how to design high with a kind of order of accuarcy, meat fiber tissue can not be cut off, pathological tissues in body is cut out wound little, go out insufficiency of blood, contact with air with intraluminal tissue without large area wound, reduce and infect probability, become the direction that those of ordinary skill in the art make great efforts.
Summary of the invention
The invention provides one for operating minimally-invasive scalpel, this minimally-invasive scalpel order of accuarcy is high, can improve therapeutic effect and can reduce tissue injury.
For achieving the above object, the technical solution used in the present invention is: a kind of for operating minimally-invasive scalpel, comprising: blade, handle of a knife and knife bar; This knife bar one end has groove, and the described handle of a knife cross section connected and composed by the first bar shaped portion and the second bar shaped portion is rectangle, and the described first bar shaped portion other end is fixed in the groove of described knife bar; The height in the first bar shaped portion higher than the height in the second bar shaped portion, the height of described blade higher than the height in the second bar shaped portion, this second bar shaped portion and form a groove area between the blade at its two ends and the first bar shaped portion; Described blade is welded on a side of described second front portion, bar shaped portion, the bottom face in blade bottom face and the second bar shaped portion is positioned at same plane and has bar weld zone between the two, has three Welding Areas between the upper surface of described blade and the upper surface in the second bar shaped portion; The knife edge of described blade and the length direction angle of blade are 79 ~ 81 °, and blade top has a chamfering inclined-plane.
The technical scheme improved further in technique scheme is as follows:
As preferably, described knife bar cross section is circular.
As preferably, the diameter of described knife bar is 1.5 ~ 1.7 millimeters.
As preferably, the rear portion being positioned at described knife bar is provided with the through hole of two parallel arrangements.
As preferably, between described first bar shaped portion and the second bar shaped portion, there is an inclined-plane connecting portion.
As preferably, described inclined-plane connecting portion and between the first bar shaped portion and the second bar shaped portion angle be 30 °.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1, the blade of Minimally Invasive Surgery cutter blade of the present invention and the length direction angle of blade are 79 ~ 81 °, substantially increase minimally-invasive scalpel accuracy; Blade top has a chamfering inclined-plane, minimally-invasive scalpel from push broach groove go out cutter cut and organize time, blade upper design one chamfering inclined-plane plays guide effect, greatly reduces blade top edge because of the resistance that brings of rubbing, thus reduces edge damage probability.
2, the blade due to minimally-invasive scalpel of the present invention is thin, fixed by Welding Area between blade upper surface and the second upper surface, bar shaped portion, and blade lower surface and the second bar shaped subordinate end face are fixed by bar weld zone, both effectively melting welding was avoided, can prevent from again snapping and embrittlement between blade and the second bar shaped portion, thus ensure that the precision of scalpel and extend the minimally-invasive scalpel life-span.
3, the present invention is used for operating minimally-invasive scalpel, its order of accuarcy is high, meat fiber tissue can not be cut off, wound is cut out to pathological tissues in body little, go out insufficiency of blood, contact with air with intraluminal tissue without large area wound, reduce and infect probability, without the need to sewing up, great shortening operating time, postoperative pain is light, recover fast, cicatrix is trickle or without cicatrix, be desirable surgical apparatus.
4, minimally-invasive scalpel knife bar of the present invention is circular, is conducive to minimally-invasive scalpel 360 ° of rotation process in scalpel assembly, improves the working place of operation.
