Definitions

  • the present invention is related to an improvement in forceps for laparoscopy procedures. More specifically it consists of a laparoscopy procedure forceps which includes an ergonomic handle which allows the operation and angling control of the active part of these forceps.
  • the laparoscopy technique has become very popular in the last decade. During this time many technical advances contributed to this progress. The surgeon for his part should be familiar with all the basic laparoscopy operating material, because this type of surgery more than any other is dependent on the good functioning of the operating material.
  • the handles allow the manipulation of the instruments, allowing the fine positioning control of the forceps and dissectors and facilitating handling.
  • the prior art concept handles have two arms ending in rings to place the fingers, where the coming together and separating movement of the thumbs and index /middle finger directly correspond to the opening and closing of the functional arms of the instrument.
  • the handles can only operate the active part of the instrument, enabling its opening and closing.
  • the present invention is related to an improvement of forceps for laparoscopy procedures which consists of a handle with a rigid shank having an articulated distal segment which enables the active part angling of these forceps.
  • An invention characteristic is an improvement in the forceps for laparoscopy procedures which allows the operation of instruments and active part angling control of the forceps in a single instrument.
  • An invention characteristic is an improvement in the forceps for laparoscopy procedures which widens the working field of the surgeon to facilitate and simplify basic hand actuation s such as: separation, grasping, traction, dissecting and bipolar coagulation.
  • Figure 1 shows the perspective view of the handle connected to a rigid shank.
  • Figure 2 shows a side view of the arm connected handle and figure 2A shows the B-B cross section view.
  • Figure 3 shows the side view of the arm connected to the handle and figure 3A shows the A-A cross section view.
  • the improvement of forceps for laparoscopy procedures consists of a handle with a rigid shank having an articulated distal segment which enables the angling of the active part of these forceps.
  • the handle consists of a handle with a first (10) and a second arm (20) interconnected in the upper end part by a fastening method (30), this first (10) and second (20) arms are arranged descending and have the ring arrangement in the lower end part (11 and 21).
  • the second arm (20) has an extension (22) in the upper end part connectable to an actuation mechanism (40).
  • a flexible structure (41) extends, this has a connection (411) which connects the extension (22) to the upper end part of the first arm (10).
  • a third arm From the lower face of the actuation mechanism (40) a third arm
  • this third arm (50) projects out descending and aligned with the first (10) and second arm (20), this third arm (50) has at the lower end part a ring arrangement (51) and in the upper end part a connection (52) with an flexible structure (41 ). From the actuation mechanism is projected a rigid shank (100) which has an active part (110) at the opposite end part to the handle, this active part (110) is arranged in a segment which has a flexing area (111 ).
  • the flexible structure (41) which activates the flexing area (111) of the active part (110) enabling the articulation of the movable segment and at the active part end (110) enabling opening and closing.
  • the third arm (50) when activated enables the angling of the active part (110) of the rigid shank (100) through flexing this active part (110) activated by the flexible structure (41 ), as shown in figures 2 and 2A.
  • the (10) and second arm (20) when activated enable the opening and closing of the active part of the rigid shank (100) through the actuation of the flexible structure (41), as in figures 3 and 3A.
  • a ratchet (200) is put between the first (10) and second (20) arms in order to allow the actuation adjustment of the active part of the instrument.

Abstract

L'invention concerne une amélioration apportée à des pinces pour des interventions laparoscopiques. Les pinces de l'invention comprennent : un manche pourvu d'un premier bras (10) et d'un deuxième bras (20) interconnectés dans la partie d'extrémité supérieure par un système d'attache (30), le deuxième bras (20) possédant une extension (22) dans la partie d'extrémité supérieure pouvant être raccordée à un mécanisme d'actionnement (40); une structure flexible (41) qui s'étend à partir du mécanisme d'actionnement (40), ladite structure flexible (41) possédant une partie de raccordement (411) qui raccorde l'extension (22) à la partie d'extrémité supérieure du premier bras (10); un troisième bras (50) qui fait saillie vers le bas à partir de la face inférieure du mécanisme d'actionnement (40), ledit troisième bras (50) possédant un anneau au niveau de la partie d'extrémité inférieure (51), et dans la partie d'extrémité supérieure une partie de raccordement (52) à la structure flexible (41); une tige rigide (100) qui fait saillie à partir du mécanisme d'actionnement (40), ladite tige rigide (100) possédant une partie active (110) disposée dans un segment qui comprend une zone de flexion (111) activée par la structure flexible (41).
