Abstract

The subject of the present invention is a surgical blade comprising a tube (1) one of the ends of which is open in the form of a sharp cutting channel (2). According to the invention, the surgical blade comprises a tube (1), one end of which is open in the form of a sharp cutting channel (2) which, when a surgical clamp (4) is introduced therein, its jaws (5) extending beyond the sharp cutting edge (2) and gripping a viscus (3), slides over the surgical clamp (4) which guides it towards the jaws (5) and cuts the viscus (3), only on one side and in line with the jaws (5), by its end in the shape of a sharp cutting channel (2), the viscus (3) on the other side of the jaws not being cut and remaining trapped in the jaws (5) of the surgical clamp (4). The surgical blade according to the invention is particularly intended for endoscopic surgery.

Description

Le domaine technique de l'invention se rapporte à la chirurgie. The technical field of the invention relates to surgery.

Lors d'une intervention chirurgicale endoscopique, on réalise simultanément les deux opérations de saisir un viscère et de le sectionner en introduisant par deux orifices différents deux instruments différents : une pince chirurgicale pour saisir le viscère et un instrument tranchant pour sectionner le viscère. Les deux instruments n'étant pas parallèles puis qutils sont introduits par deux orifices différents, il est difficile de sectionner régulièrement et au ras des mors de la pince chirurgicale le viscère.During an endoscopic surgical intervention, the two operations are carried out simultaneously to grasp a viscera and to cut it by introducing two different instruments through two different orifices: surgical forceps to grasp the viscera and a cutting instrument to cut the viscera. The two instruments not being parallel since they are introduced through two different orifices, it is difficult to regularly section and flush with the jaws of the surgical forceps the viscera.

La présente invention a pour objet un couteau chirurgical perfectionné qui remédie à ces inconvénients. The present invention relates to an improved surgical knife which overcomes these drawbacks.

Ce couteau chirurgical comprend un tube dont l'une de ses extrémités est ouverte en forme de gouttière coupante et tranchante. This surgical knife comprises a tube, one of its ends of which is open in the form of a cutting and sharp gutter.

Ce couteau chirurgical est introduit dans la cavité dans laquelle on intervient, soit directement par un orifice son autre extrémité est alors munie d'une soupape, soit dans une canule déjà munie d'une soupape. Dans le tube du couteau chirurgical est introduit une pince chirurgicale. Aussi un seul orifice est utilisé pour introduire les deux instruments : la pince chirurgicale et le couteau chirurgical. Les mors de la pince chirurgicale dépassant l'extrémité coupante et tranchante du couteau chirurgical peuvent s'ouvrir et saisir le viscère. Le couteau chirugical est alors manoeuvré en le faisant glisser sur la pince chirurgicale qui lui sert de guide en direction des mors de la pince chirurgicale. This surgical knife is introduced into the cavity in which one intervenes, either directly through an orifice its other end is then provided with a valve, or in a cannula already provided with a valve. A surgical forceps is inserted into the tube of the surgical knife. Also a single hole is used to introduce the two instruments: the surgical forceps and the surgical knife. The jaws of the surgical forceps protruding from the cutting and sharp end of the surgical knife can open and grip the viscera. The surgical knife is then maneuvered by sliding it over the surgical forceps which serves as a guide in the direction of the jaws of the surgical forceps.

D'un côté des mors de la pince chirurgicale et du côté de la gouttière coupante et tranchante du couteau chirurgical le viscère est sectionné par la gouttière coupante et tranchante régulièrement et au ras des mors de la pince chirurgicale. Du côté opposé à la gouttière coupante et tranchante, le viscère n'est pas sectionné et reste prisonnier des mors de la pince chirurgicale. On one side of the jaws of the surgical forceps and on the side of the cutting and cutting gutter of the surgical knife, the viscera is sectioned by the cutting and cutting gutter regularly and flush with the jaws of the surgical forceps. On the side opposite to the cutting and sharp gutter, the viscera is not cut and remains trapped in the jaws of the surgical forceps.

On a décrit ci après, à titre d'exemple non limitatif, un mode de réalisation du couteau chirurgical selon l'invention avec référence au dessin annexé dans lequel
La figure 1 est une vue en élévation du couteau chirurgical
La figure 2 est une vue à plus grande échelle de l'extré- mité du couteau chirurgical coupante et tranchante
La figure 3 est une vue en perspective de l'extrémité du couteau chirurgical coupante et tranchante
Les figures 4 a à 4 d sont des schémas montrant l'utilisation du couteau chirurgical selon l'invention.
An embodiment of the surgical knife according to the invention has been described below, by way of non-limiting example, with reference to the attached drawing in which
Figure 1 is an elevational view of the surgical knife
Figure 2 is an enlarged view of the end of the cutting and sharp surgical knife
Figure 3 is a perspective view of the end of the cutting and cutting surgical knife
Figures 4 a to 4 d are diagrams showing the use of the surgical knife according to the invention.

Tel qu'il est représenté au dessin, le couteau chirurgical selon l'invention comporte un tube 1 dont une extrémité est ouverte en forme de gouttière coupante et tranchante 2. As shown in the drawing, the surgical knife according to the invention comprises a tube 1, one end of which is open in the form of a cutting and sharp gutter 2.

Pour sectionner le viscère 3 on introduit dans le tube du couteau chirurgical 1 une pince chirurgicale 4, les mors de la pince chirurgicale 5 dépassant l'extrémité coupante et tranchante du couteau chirurgical 2 peuvent s'ouvrir (figure 4a) et saisir le viscère 3 (figure 4b). Le tube du couteau chirurgical 1 est manoeuvré en le faisant glissé sur la pince chirurgicale 4 qui de sert de guide en direction des mors de la pince chirurgicale 5 en dirigeant la gouttière coupante et tranchante 2 du côté des mors 5 où le viscère 3 désire être sectionné. On poursuit la manoeuvre, la gouttière coupante et tranchante 2 sectionne alors le viscère 3 d'un seul côté et au ras des mors de la pince 5 (figure 4c). On retire le couteau chirurgical 1, le viscère sectionné 3 est alors prisonnier des mors de la pince chirurgicale 5 (figure 4d).  To cut the viscera 3, a surgical forceps 4 is inserted into the tube of the surgical knife 1, the jaws of the surgical forceps 5 projecting beyond the cutting and sharp end of the surgical knife 2 can open (FIG. 4a) and grasp the viscera 3 (Figure 4b). The tube of the surgical knife 1 is maneuvered by sliding it over the surgical forceps 4 which serves as a guide in the direction of the jaws of the surgical forceps 5 by directing the cutting and cutting gutter 2 towards the jaws 5 where the viscera 3 wishes to be sectioned. The maneuver is continued, the cutting and cutting gutter 2 then cuts the viscera 3 on one side and flush with the jaws of the forceps 5 (FIG. 4c). The surgical knife 1 is removed, the severed viscus 3 is then trapped in the jaws of the surgical forceps 5 (FIG. 4d).

Le couteau chirurgical selon l'invention est particulièrement destiné à la chirurgie endoscopique. The surgical knife according to the invention is particularly intended for endoscopic surgery.

I1 va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et représenté, mais en couvre au contraire toutes les variantes.  It goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants thereof.
