Abstract
The invention discloses a surgical knife special for cutting a membranous tissue and belongs to a medical surgical instrument, in particular to the surgical knife special for cutting the membranous tissue. The surgical knife consists of a knife rest and a knife blade, wherein a knife rest body consists of a knife handle 1 and a knife head; the front end of the knife head is a guide head 4; the back part of the guide head is provided with an upright knife blade 3; a back support 2 is arranged obliquely above the knife blade; and the guide head has a circular arc shape and is flat. The knife rest, the knife blade 3 and the like can be manufactured respectively and assembled with each other, and the knife rest can also be manufactured from organic materials such as plastic and the like and arranged and molded with the knife blade by pouring at one step, so that the surgical knife is suitable for dispensable use. The guide head has smooth appearance, so that the surgical knife has the advantages that: the surgical knife avoids damaging a tissue structure under the membranous tissue accidentally, cuts correctly and is easy and convenient to operate.
Description
Technical field
The invention belongs to a kind of medical surgery surgical instrument, particularly belong to a kind of special-purpose surgical knife that is used for membranaceous tissue cutting.
Background technology
In surgical operation,, still there is not special equipment as the cutting of thigh fascia lata, muscle sheath, peritoneum etc. for membranaceous tissue.Current practice is: scratch osculum with scalpel at membranaceous tissue, strut with mosquito forceps, bit by bit cut with the general surgery cutter, cut on the temple limit, often needs two people's compounding practices.Or tissue cut insert in the otch, cut on the temple limit, bit by bit cuts off.Because it is sharp-pointed that above-mentioned used scalpel or tissue are cut front end, and visual bad, thus other organizational structure under the membranaceous tissue accidentally injured easily, and operation is slowly.
Summary of the invention
Purpose of the present invention promptly is to provide a kind of novel membranaceous tissue cutting special-purpose surgical knife, with the purpose that reaches easy to use, quick, avoids accidentally injuring other organizational structure under the membranaceous tissue.
Membranaceous tissue cutting special-purpose surgical knife disclosed in this invention is made up of knife rest and blade, and knife rest is made of handle of a knife and cutter head, it is characterized in that, the front end of cutter head is a seeker, and there is axial blade at the rear portion of seeker.
Membranaceous tissue cutting special-purpose surgical knife disclosed in this invention, seeker profile slyness, front end is pointed the upwarping of finger.Except that playing guiding function, can also separate that other organizational structure makes it to dodge under the membranaceous tissue, and membranaceous tissue can be provoked, be convenient to blade cuts, so have good effect easy to use, as can not stab other tissue.
Description of drawings
Accompanying drawing partly discloses specific embodiments of the invention, is further described below in conjunction with accompanying drawing:
Fig. 1, membranaceous tissue cutting special-purpose surgical knife front view;
Fig. 2, membranaceous tissue cutting special-purpose surgical knife vertical view;
Fig. 3, A-A is to view;
Fig. 4, B-B is to view.
The specific embodiment
As shown in Figure 1 and Figure 2, membranaceous tissue cutting special-purpose surgical knife disclosed in this invention, its knife rest is made of handle of a knife 1 and cutter head.The front end of cutter head is a seeker 4.For avoiding stabbing other tissue, as Fig. 2, shown in Figure 4, seeker 4 is circular arc, flat, pointed the upwarping of front end finger.The end of handle of a knife 1 has horizontal holding rod 7, is convenient to grip and operation.
As shown in Figure 1, at the rear portion of seeker 4, there is axial blade 3 junction of seeker 4 and handle of a knife 1, and blade forward.Blade in the present embodiment, its blade is rectilinear, can be arc also, or has " L " shape of bending.But the blade rail head, certain angle also can recede.
In addition, be protection blade and play better support fixation effect, and avoid injuring its thing, be provided with a thumb back up 2 at the oblique upper of blade, lump together with bulk junction, blade promptly is installed in the angle of back up and body formation.For better fixed installation blade 3, on above-mentioned back up 2, be provided with fastening bolt 6, cooperate with the screwed hole of presetting on the back up.
As Fig. 1, shown in Figure 3, the rib shape projection 5 of suitable cut direction is arranged in the installation position of blade.Rib shape projection 5 bootstrap heads swell gradually along center line, and extending back slightly increases to blade, coincide with the blade bottom.Rib shape projection can make membranaceous tissue local tighten when cutting, has the effect that increases tension force, is convenient to cut.
Membranaceous tissue cutting special-purpose surgical knife disclosed in this invention, related knife rest can utilize organic materials such as metal material or plastics to make, and assembles with blade 3 then.Perhaps, tool holder body adopts organic material such as plastics to make, and with blade once mounting moulding by casting, can reach and reduce cost, be fit to disposable purpose.Described seeker 4 parts preferably are made into dark colours such as redness, purple, black, may be seen indistinctly under translucent membranaceous tissue, can bring into play better guiding function.
Membranaceous tissue cutting special-purpose surgical knife disclosed in this invention in use, is at first scratched osculum at membranaceous tissue, seeker is stretched under the membranaceous tissue, and membranaceous organizing gently provoked, and slowly promotes forward, and axial blade is about to membranaceous tissue and severs.Since seeker profile slyness, and can be close to membranaceous tissue after provoking, profile is high-visible under membranaceous tissue, and color is may be seen indistinctly, so have the good effect of avoiding accidentally injuring, cutting accurate, easy operation, simple operation.
