Definitions
- the present invention relates to surgical devices for making and locating an orifice in a wall located in a soft opaque medium for the purpose of performing, at least at said orifice, a given surgical procedure.
- the device described in this document comprises an oblong drill rod having a cross section of a given value, a cylindrical thin pin having a cross section of a value less than that of the cross section of the drill rod, and a longitudinally formed breakthrough in the drill rod, the piercing having a cross section of a shape substantially complementary to at least a portion of that of the thin pin so that the latter is adapted to be guided by sliding.
- the present invention aims to achieve an improvement, in particular to promote the sliding of the thin pin relative to the drill rod and to further facilitate its use by surgeons. More specifically, the present invention relates to a surgical device for making an orifice in a wall located in a soft opaque medium and locate it in order to perform, at least at this orifice, a given intervention having the characteristics listed in particular in the appended claims 1 or 2.
- Figures 1 to 3 show three schematic views illustrating the implementation of the surgical device according to the prior art described in FR 2 911 804 to achieve by locating an orifice in a wall located in a soft opaque medium for the purpose of performing, at least at the orifice, a given surgical procedure, when this wall is made of a relatively hard and / or rigid and / or friable material, and
- FIGS. 4 and 5 show two views illustrating the preferred embodiment of the improved device according to the invention, FIG. 4 being a front view and FIG. 5 being a cross-sectional view referenced V-V in FIG. 4.
- the present invention relates to a surgical device for making an orifice 1 in a wall 2 located in a soft opaque medium 3 and locate it in order to perform, at least at this orifice, a given medical intervention.
- opaque medium soft 3 means a medium of any kind not transparent visible radiation, such as a fluid or semi-fluid, elastic, or semi-elastic body, etc., such as the skin, muscles, etc., which, after being pierced, closes on itself .
- Another operation is to perform the assembly of at least one thin pin 12 in cooperation with the drill rod 10, by mutual sliding in a longitudinal bore 20 formed in the drill rod, so that a first end 14 of the thin pin 12 is located in at least a portion of the orifice 1 and that its other end 16 is located outside the soft opaque medium, that is to say in the outer space 30 delimited by the face 17 of the opaque medium 3 opposite on its face 18 which is opposite the wall 2, figurel.
- the face 18 is shown in contact with the wall 2.
- Another operation consists in maintaining the thin pin 12 so that its first end 14 remains in the orifice 1 when, by sliding the drill rod 10 with respect to the thin pin 12, FIG. 2, the drill rod 10 is removed from the orifice 1 that she made.
- the last operation is to perform the action given at the orifice 1 by guiding along the thin pin 12, FIG.
- the thin pin 12 can be slid along the drill rod 10 after completion of the orifice by means of the drill rod, and before the latter is removed from the orifice 1. But the implementation of these first two operations can also be carried out as follows: the thin pin 12 is slid along the drill rod 10, then the orifice 1 is made with the drill rod 10 carrying the thin pin 12, and finally the drill rod is removed of the orifice 1 leaving in place the thin pin 12 so that its first end 14 dips into the orifice 1.
- the thin pin 12 will be positioned along the drill rod 10 so that its first end 14 is located in at least a portion of the orifice 1 when it has been realized .
- the second mode of implementation is however preferable because, by positioning the first end 14 of the thin pin near the piercing tip 19 of the drill rod 10 before the embodiment of the orifice 1, it is certain that this first end 14 will dive into this hole.
- the improvement according to the invention provided to this device consists in that it comprises, as mentioned above, a cylindrical drill rod 10 advantageously of revolution defined along a longitudinal axis 11 and having a cross section of a given value, a cylindrical thin pin 12 advantageously of revolution and a longitudinal groove 20 formed in the drill rod 10 substantially parallel to the longitudinal axis 11 and opening on the side surface 24 of the drill rod 10 through a longitudinal opening 200.
- the longitudinal groove 20 is made, Figures 4 and 5, so that its depth and the width of the longitudinal opening 200 are determined so that when the thin pin 12 slides along the groove, this pin does not rests only on the two edges 200-1, 200-2 of the longitudinal opening 200, these two edges constituting low friction guide rails for the thin pin during its sliding relative to them.
- the device comprises a cylindrical drill rod advantageously of revolution 10 defined along a longitudinal axis 11 and having a cross section of a given value, a cylindrical thin pin 12 of axis 22 and a radius of value Ray having a cross section of a value less than that of the cross section of the drill rod 10, and a longitudinal groove 20 of substantially cylindrical shape made in the drill rod 10 substantially parallel to the longitudinal axis 11 and opening on the side surface 24 of the drill rod 10 by a longitudinal opening 200 of a width of value Val less than double Ray.
- this longitudinal groove 20 is made to have a depth greater than the difference between (i) the value Ray, and (ii) the value of the difference between the value Ray and the value of the distance between the axis 22 of pin 12 and a chord of the circular section of this pin having a length of value Val, so that, by sliding along the groove, the pin rests only on the two edges 200-1, 200-2 defined by the common edges of this groove and the cylindrical lateral surface of the drill rod 10.
- the device comprises reference means connected to the drill rod 10 for indexing the position of the longitudinal groove 20 with respect to this drill rod 10, for example at the top of this rod, since after having implanted it and before sliding the pin 12 along the groove, it is sometimes difficult in the operating environment to properly note the position of the entrance of this groove.
- Such a mark may consist of a raised rib 100 made at the top of the drill rod 10, the top of this rod being its end opposite its penetrating end 19.
- each of the two edges 200-1 and 200-2 is constituted by the top of an acute dihedron to limit as much as possible the friction forces when the pin slides on the drill rod.
- such a drill rod 10 is of the drill type or the like made of a rigid metallic material such as steel or the like, with a cylindrical body generally of revolution terminated by a piercing tip 19, for example in the form of gouge or the like, which allows to make orifices generally by rotation about the longitudinal axis of the drill rod 0.
- the thin pin 12 is generally made of a rigid metallic material such as steel or the like and is in the form of a needle or the like which is as thin as possible while still having good rigidity over its entire length, although it may slightly bend.
