Description
- The invention relates to the field of surgical instruments, and in particular the instruments used manually by a practitioner to grasp body tissues.
- The invention more particularly relates to a surgical phlebectomy forceps.
- A phlebectomy is a surgical operation, primarily affecting the lower limbs, which consists of removing segments of varicose veins, said varicose veins being unattractive, painful, and accompanied by an alteration in the circulatory condition which carries a risk of complications.
- To allow this removal, the surgeon makes an incision in the patient's skin. He then grasps the vein using a hook known as a “Muller hook,” then removes it using “Halsted” or equivalent forceps, inserted into the incision.
- However, the use of this type of forceps has the drawback of requiring a relatively large incision, i.e. at least 4 to 5 mm. In fact, the width of the jaws, and particularly the branches, requires a large incision, In particular, the spacing of the branches when the forceps is opened is relatively significant and increases the necessary size of the incisions.
- Furthermore, the larger the radius of action of the forceps, the larger the space between the branches. Thus, when the segments of vein to be removed are at a significant distance from the incision, the practitioner must use a forceps with a significant length and the incision formed must be that much larger. Thus, in practice, practitioners prefer to make a number of incisions so as to limit the distances between the incisions and the vein segments to be removed and, as a result, the width of the incisions.
- Furthermore, these forceps are not very ergonomic. On the one hand, they do not allow sufficient gripping of the vein segments, such that the practitioner is sometimes several attempts by the practitioner are sometimes necessary to remove them. On the other hand, the manipulation of the handling branches near the patient's skin is not easy.
- The invention aims to resolve these problems by proposing an ergonomic surgical phlebectomy forceps making it possible to decrease the size and number of incisions necessary to remove all of the varicose veins.
- To that end, and according to a first aspect, the invention proposes a surgical forceps for removing varicose veins including:
-
- a body with an articulation plate and an elongate tubular sheath;
- two maneuvering branches mounted on the articulation plate and movable relative to each other between an open position and a closed position, each of these branches having a ring for the insertion of a finger;
- a gripper mounted at the distal end of the tubular sheath and having two jaws mounted movably relative to each other around an axis A between an open position and a gripping position, the inner faces of said jaws being toothed in order to hold the varicose veins; and
- means for transmitting the movement of the maneuvering branches to the jaws, via the tubular sheath, said means being designed to move the jaws to their gripping position when the maneuvering branches are closed together.
- Thus, when the forceps is positioned in its position to remove the vein, it is the tubular sheath that is positioned at the incision. However, the sheath has a limited section which also does not vary as a function of the position of the maneuvering branches or the jaws. In this way, the section of the tubular sheath being limited, the width of the incision may be limited.
- Furthermore, the presence of a device for transmitting the movement of the maneuvering branches to the jaws, through the sheath, makes it possible to increase the radius of action of the forceps without increasing the width of the incision. The forceps according to the invention then makes it possible to remove veins under the same conditions, whether they are close to or far away from the incision. Consequently, the number of incisions made during an operation may be significantly decreased.
- Advantageously, the rings are spaced apart by a distance of at least 1 cm relative to a working plane, orthogonal to the axis A, in which the jaws extend. This embodiment makes it possible to facilitate maneuvering of the forceps, as the rings are thus spaced away from the patient so as to form a free space between the patient and the maneuvering rings.
- Advantageously, the rings extend in a maneuvering plane inclined by an angle greater than 10° relative to the working plane and, preferably, inclined by an angle comprised between 20 and 30° relative to the working plane.
- Advantageously, the length of the tubular sheath is comprised between 10 and 25 cm. Preferably, the tubular sheath has a section smaller than or equal to 3 mm. In this way, the tubular forceps according to the invention makes it possible to remove veins situated more than 25 cm from the incision without requiring an incision having a width greater than 3 mm.
- Advantageously, the inner faces of the jaws have toothed surfaces with complementary shapes. This arrangement allows satisfactory maintenance of the vein segments in the gripper during the operation.
- Advantageously, the jaws are provided at their distal end with one or more claws. These claws allow anchoring of the jaws in the vein wall so as to allow easy removal of the veins.
- According to one embodiment of the invention, the means for transmitting the movement include a shaft translatable inside the tubular sheath and two connecting rods each having a first end rotatably mounted on one of the branches and a second end rotatably mounted on one end of the shaft. In this way, these transmission means are particularly simple.
- Advantageously, a first jaw is movably mounted relative to a second stationary jaw, around the axis A, and the distal end of the moving shaft is equipped with a connecting rod that is on the one hand movably mounted on said first jaw around a second axis B not combined with the axis A, and on the other hand mounted rotatably on the distal end of the shaft.
- According to a second aspect, the invention relates to an assembly including a set of surgical forceps according to the first aspect of the invention, each of said forceps comprising tubular sheaths of different lengths.
- Other aims and advantages of the invention will appear upon reading the following description, done in reference to the appended drawings, in which:
