Definitions
- the present invention relates to the field of medical devices for surgical suturing by endoscopic method, and more particularly by flexible endoscopy.
- Endoscopic surgery is a method of visual exploration of the interior of a cavity using optical tubular equipment introduced either through the body's natural orifices (flexible endoscopy) or through incisions of a few millimeters in the cavity. skin (laparoscopy). This method allows the insertion and use of instruments within the body in order to carry out surgical operations. This type of minimally invasive surgery offers many advantages over traditional surgical techniques (reduction in post-operative pain, recovery time and complications, etc.).
- miniaturized instruments have thus been proposed for this purpose, and in particular forceps, scissors, electric scalpels, etc. All these miniaturized instruments are designed to be introduced into the body either through small-section trocars (laparoscopy) or through the working channel of flexible endoscopes.
- surgeons have various techniques at their disposal. These techniques consist either of placing staples or clips or of performing suturing by remotely activating a needle carrying a suture thread.
- the present invention belongs to this last family of solutions.
- the invention relates more particularly to the family of curved needles adapted to new techniques for suturing in flexible endoscopy.
- a camera needle adapter which comprises a tube-shaped body having a proximal end, a distal end, a longitudinal axis and a lumen which extends the along the longitudinal axis.
- a centrally located side access opening is formed in an outer wall of the tube-shaped body.
- a needle attachment channel is formed in the outer wall and extends between the side access opening and the distal end of the tube-shaped body.

- the axial forward translation (towards the intestinal lumen) of the gripping tool (300) thus makes it possible to extract the surgical needle (200) from the said longitudinal groove(s). (104) by pushing it towards the distal end (102) of the cap (100), towards the intestinal lumen, making it possible to gradually deliver said surgical needle (200) into the gastrointestinal tract without ever letting go.
- the needle gripping tool (300) being rotatable, the surgical needle (200) is itself progressively and precisely controllable in rotation when held by the gripping tool (300). .
- the holding means (105) of the suture thread (210) is provided by a groove-shaped housing dug into the internal face of the tubular wall (103) of the cap (100) so as not to increase the diameter of this one. Indeed, the smaller the diameter, the easier the handling of the invention and its passage through the gastrointestinal tract (particularly in the esophagus).
- the means for holding said suture thread (210) is constituted by one or more circular groove(s) (105).
- the hold can also be achieved by gluing, for example by a glue allowing release when traction is exerted on the needle (200).
- said circular groove(s) (105) is/are arranged at the distal end (102) of the cap (100) near its opening as illustrated on the . It(s) are located in a transverse plane located at the distal end of the longitudinal groove(s) (104) for holding the surgical needle (200).
- the suture thread (210) emerging from one of the pointed ends (202) of said surgical needle (200) will travel through the longitudinal groove(s) (104) allowing said surgical needle (200) to be held in place. ) before winding into the circular groove(s) (105).
- said circular groove(s) (105) is/are arranged at the proximal end (101) of the tubular wall (103) of the cap ( 100); it(s) are therefore located upstream of the longitudinal groove(s) (104).
- the circular groove(s) (105) for holding the suture thread is/are in relief relative to the surface of the tubular wall (103) of the cap (100).
- the circular groove(s) (105) is/are represented by an addition of material in the shape of a crown relative to the surface of the tubular wall (103) of the heading (100).
- the circular groove(s) (105) is/are represented by a withdrawal of material relative to the surface of the tubular wall (103) of the invention forming a narrow slot in the thickness of the tubular wall (103) of the cap (100).
- This embodiment makes it possible to avoid reducing the endoscopist's field of vision by not adding additional thickness to that of the tubular wall (103) of the cap (100).
- the circular groove(s) (105) for holding the suture thread (210) is/are arranged over the entire circumference of the invention parallel to the tubular wall (103) of the invention in order to allow the entire length of the wire to be stored without hindering the visibility of the endoscopist or the passage of tools.
- the holding zones (105) of the suture thread (210) are not continuous but constituted by a succession of holding segments.
- the thread can be held in place by temporary bonding, which does not resist traction exerted by the operator or by friction in the groove.
