Definitions
- the present invention relates to a bipolar forceps for pelviscopy allowing the coagulation of tissues.
- Clamps of this kind which are made of two parallel metal blades connected to a voltage source to use the blades as electrodes.
- the forceps include means for moving the blades relative to one another, when the latter is introduced into a cannula or trocar to deform the free ends of each blade in order to pinch the tissues to be coagulated.
- the displacement means generally consist of two handles, one of which is movable to allow the blades to slide inside the cannula or the trocar in order to deform the ends.
- clamps have an outside diameter of approximately 5 millimeters, which is too large to penetrate guides or cannulas of smaller diameter which are provided between 1, 5 and 3 millimeters of internal diameter.
- the metallic material used for the constitution of the blades such as of the alloy, does not make it possible to reduce the external diameter of the clamp without risking deteriorating its operation.
- bipolar forceps The purpose of the bipolar forceps according to the present invention is to be able to be inserted inside guides or cannulas whose internal diameter is less than 5 millimeters, while guaranteeing perfect functioning of the blades during their elastic deformation.
- a cylindrical support allowing, on the one hand the connection of the pair of blades to the guide, and on the other hand by means of elastic means the return of the pair of blades in a determined position, • and means for connecting the pair of blades to a voltage source so that each blade operates on an electrode to allow the coagulation of the tissues.
- each blade is made of a shape memory alloy of the hyper-elastic type in order to be able to have a very small outside diameter and a significant deformation of the ends.
- the bipolar forceps according to the invention is characterized in that the blades have, along the length of the sheathed part, an oblong profile of constant thickness.
- the bipolar forceps according to the invention is characterized in that the non-sheathed ends of the blades have an oblong profile whose thickness is less than that provided for the sheathed part allowing better elastic deformation under external stress on the one hand , and a larger contact surface facilitating tissue coagulation on the other hand.
- the bipolar forceps according to the invention is characterized in that the blades are joined together by means of a cylindrical tube which has at each end circular deformations allowing the longitudinal locking of the blades between them.
- the bipolar forceps according to the invention is characterized in that the tube has on its periphery and near a deformation a circular stop.
- the bipolar forceps according to the invention is characterized in that the blades are belted in another sheath over the entire length of the first sheath allowing them to be fixed together so as to prevent them from moving longitudinally relative to one another .
- the bipolar forceps according to the invention is characterized in that the tube and the blades are arranged inside a cylindrical support comprising at one end, and more particularly that turned on the side of the jaws, connection means which allow the attachment of the clamp on a small diameter guide.
- the bipolar forceps according to the invention is characterized in that the cylindrical support comprises, opposite the end carrying the connection means, elastic return means which consist of a handle and a return spring housed in the internal part of said support to come into abutment against the stop of the cylindrical tube.
- the bipolar forceps according to the invention is characterized in that the cylindrical support comprises, near the connection means, a sealed connection of the tap type for the introduction of a fluid into the internal channel of the guide and into the operating site.
- the bipolar forceps according to the invention is characterized in that the cylindrical support comprises elastic return means which consist of a handle formed by a curved and flexible branch which comes to bear against a housing of the voltage source.
- the bipolar forceps according to the invention is characterized in that the cylindrical support comprises, opposite the handle secured to its branch, a sealed connection of the tap type for the introduction of a fluid into the internal channel of the guide and in the operating site.
- Figures 1 and 2 are views illustrating the bipolar forceps for pelviscopy according to the present invention.
- FIGS 3 and 4 are detail views showing the arrangement of hyperelastic blades of the forceps for pelviscopy according to the present invention.
- Figure 5a is a section along AA of Figure 4, showing the sheathing of the hyperelastic blades of the forceps for pelviscopy according to the present invention.
- Figure 5b is a section similar to that of Figure 5a illustrating a variant of the sheathing of the hyperelastic blades of the forceps for pelviscopy according to the present invention.
- Figure 5c is a section along BB of Figure 4, showing the profile of the end, unsheathed, of the hyperelastic blades of the forceps for pelviscopy according to the present invention.
- Figure 5d is a section along CC of Figure 3, showing the attachment of the hyperelastic blades inside the forceps tube for pelviscopy according to the present invention.
- Figure 5e is a section along DD of Figure 3, illustrating the passage of the hyper-elastic blades inside the forceps tube for pelviscopy according to the present invention.
- Figures 6a to 6e are partial views showing the maximum stroke for the deformation of the hyper-elastic blades inside the guide of small diameter.
- Figure 7 is a view showing the cylindrical support of Figure 1 provided with fluid supply means of the internal channel of the guide receiving the clamp for pelviscopy according to the present invention.
- Figure 8 is a view illustrating a variant of the cylindrical support and more particularly elastic return means of the forceps for pelviscopy according to the present invention.
- Figure 9 is a view showing a variant of the cylindrical support of Figure 8 on which are provided means for feeding the internal channel of the guide receiving the forceps for pelviscopy according to the present invention.
- FIGS. 1 to 4 have shown a bipolar forceps 1 for pelviscopy comprising a pair of blades 2 which are connected to a voltage source 3, so that each blade functions according to an electrode for the coagulation of the tissues.
- Each blade 2 is made of a shape memory alloy of the hyperelastic type in order to be able to have a very small outside diameter, of the order of 1.6 millimeters, and a significant deformation of the ends of said blades.
- the blades 2 are partially covered with a plastic sheath 4 making it possible to isolate them from one another over a large part of them. It is noted that the blades 2 have over the length of the sheathed part 4 an oblong profile of constant thickness ( Figures 5a, 5b).
- the blades 2 each have one end 5, not sheathed, constituting the jaws of the bipolar forceps 1. It is noted that the ends 5 of the blades 2 have an oblong profile whose thickness is less than that provided for the sheathed part 4 (FIG. 5c). The thinner profile of the ends 5 of each blade 2 allows better elastic deformation under external stress on the one hand, and a larger contact surface facilitating the coagulation of the tissues on the other hand.
- the blades 2 are joined together by means of a cylindrical tube 6 which has circular deformations at each end 7 allowing the longitudinal locking of the blades between them and of preventing said blades from being able to move relative to one another. the other.
- the tube 6 has on its periphery, and near a deformation 7, a circular stop 8 making it possible to limit the longitudinal travel of the blades 2 (FIG. 5d, 5e).
- the latter Prior to the fixing of the blades 2 to each other inside the tube 6, the latter can be belted in another sheath 9 over the entire length of the first sheath 4.
- the sheath 9 can also replace the tube 6, because the belt of the latter around the blades 2 allows them to be fixed together so as to prevent them from moving longitudinally relative to one another (FIG. 5b).
- the tube 6 and the blades 2 are disposed inside a cylindrical support 10 comprising at one end, and more particularly that turned on the side of the jaws 5, connection means 11 which allow the clamp 1 to be fixed on a small diameter guide 12.
- the cylindrical support 10 comprises, opposite the end carrying the connection means 11, elastic return means 13 which consist of a handle 14 and a return spring, not shown, but housed in the part internal of said support to come into abutment against the stop 8 of the cylindrical tube 6.
- the clamp 1 has, before any introduction into a small diameter guide 12, jaws 5 which are always in the open position due to the curved profile which has been given to the blades 2.
- the elastic return means 13 determine the maximum longitudinal stroke that the blades 2 can make inside the support 10 and the guide 12.
- the closed position is obtained by the fact that the latter penetrate sufficiently inside an internal channel 15 of the guide 12 to deform the curved profile of the jaws 5 and apply them one against the other. the other.
- rest position is meant the position of the clamp 1 introduced into the operating site via the small diameter guide 12 and before any use of said clamp by the surgeon.
- the longitudinal displacement of the housing 16 in the direction of the support 10 makes it possible to slide the blades 2 inside said support and of the guide 12 in order to free the jaws 5 from the internal channel 15 (FIG. 6a).
- the surgeon can position between the open jaws 5 of the blades 2, tissues to be cauterized, such as blood vessels or the like.
- the surgeon gradually releases the housing 16 so that the elastic return means 13 move the blades 2 longitudinally relative to the guide 12 and inside the channel 15 to close the jaws 5 around the tissue to be cauterized (FIG. 6b to 6e). It then suffices to apply at the jaws 5 a sinusoidal voltage of the high frequency type via the tension source 3, in order to cauterize or coagulate the tissue.
- the surgeon opens the jaws 5 to release the cauterized tissue by pressing the housing 16 again so that the blades 2 slide inside the guide 12 (FIG. 6a).
- Figure 7 there is shown a first variant of the support 10 of Figure 1 with regard to the establishment near the connection means 11 of a sealed connection 17 of the tap type for introduction into the internal channel 15 of the guide 12 and in the operating site of a fluid.
- FIG. 8 a second variant of the support 10 of FIG. 1 has been shown with regard to the elastic return means 13 which consist of a handle 14 formed of a curved and flexible branch 18 which bears against the housing 16 of the voltage source 3.
- the branch 18 makes it possible to replace the spring introduced inside the support 10 and which comes to bear against the stop 8 of the cylindrical tube 6.
- FIG. 9 shows a variant of the support 10 of FIG. 8 which consists of having, opposite the handle 14 secured to its branch 18, a sealed connection 17 of the tap type for introduction into the internal channel 15 and in the operating site of a fluid.
- the guide 12 on which the support 10 of the clamp 1 is fixed can be, for example, the universal catheter described in the French patent application FR 97 13988 belonging to the applicants.
- the use of the universal catheter as guide 12 allows the surgeon to perform a particular operation related to fertilization by coagulation of the tubes.
