Abstract

The invention relates to the production of a vertical gastric resevoir for the surgical treatment of morbid obesity. Said reservoir consist of a clamp comprising two plates articulated at the lower end thereof and an automatic closing system in the upper part thereof, reinforced with a sealing system. Both plates are provided with two extensions (one at each end of the instrument) on the right-hand edge thereof. Both extentions are provided with two openings that are used to fix the instrument to the stomach wall. The application of said instrument and the technical solution provided are as follows: the substitution of metal staples which are subsequently eliminated in between 15% and 20% of patients and which result in failure of the vertical band gastroplasty operation. Eventually, and instrument coulb also be used for producing small gastric reservoirs used for gastric bypass with minor curvature instead of metal staples.

Claims

1. Gastric clamp for Vertical Band Gastroplasty (V.B.G.) and gastric By-pass with a minor curve.

2. Gastric clamp, according to claim 1, characterised by having a frame in which two articulated plates, a closing system, a sealing or reinforcement system, a curvilinear configuration of blunt edges with a flat internal surface, a system for fixing to the stomach and an overall covering are included.

3. Gastric clamp, according to claim 2, characterised by both plates being articulated at the lower end, by means of a hinge system, with a stop that permits rotation of 180°

over the axis.

4. Gastric clamp, according to claim 3, characterised by its external configuration being curvilinear, with blunt edges and its internal surface being flat.

5. Gastric clamp, according to claim 4, characterised b having an automatic closing system at the open end of both plates.

6. Gastric clamp, according to claim 5, characterised by having a sealing or reinforcement system, in the form of a female part (independently of the rest of the instrument), that that embraces the open end of the clamp along a length of 1.25 cm, once this is in the closed position.

7. Gastric clamp, according to claim 6, characterised by the system of fixing to the stomach on the right edge of the clamp having two wide parts, located on their upper end and on the lower one, each wide part with two holes, that allows for the passage of button sutures.

8. Gastric clamp, according to claim 7, characterised by the entire instrument being manufactured in titanium or in an inert plastic material.

9. Gastric clamp, according to claim 7, characterised by the entire instrument being covered in P.T.F.E. or Teflon.

10. Gastric clamp, according to claims 8 and 9, characterised by the plates being 8.5 cm in length and 10 mm wide.
