Definitions

  • the present invention patent application relates to a surgical stapler group and a surgical instrument , in particular an accessory for a surgical instrument generally known as a laparoscopic stapler .
  • the present invention relates to a surgical stapler group and a laparoscopic surgical instrument for bariatric surgery .
  • Bariatric surgery includes all those surgical interventions aimed at reducing or removing, at least partially, the stomach in order to reduce the weight of people suf fering from obesity .
  • Known surgical techniques include : SLEEVE GASTRECTOMY, GASTRIC BYPASS, and GASTRIC BANDING. Apart from gastric banding, the known surgical techniques require extensive gastric resections and gastro-intestinal anastomoses . This is made possible by surgical instruments , in particular accessories for a laparoscopic stapler, generally known as staplers .
  • Well-known laparoscopic staplers have a substantially scissor-like structure with two opposing arms , which are guided in a known way in order to be operated remotely by a laparoscopic stapler .
  • one of the two arms includes a blade , which cuts through the tissues as the arms are brought together so that they press against each other .
  • Laparoscopic staplers of the type described above further comprise cartridges configured to apply staples at the same time as the cut and along both sides of the blade . Therefore , a laparoscopic stapler of the type described above is configured to perform a tissue section line and, at the same time , apply layers of staples to the sides of the section line to suture the cut edges .
  • Figure 1 schematically shows a person' s abdomen indicating the positions (numbered with Roman numerals from I to V) of the incisions that are normally made during a bariatric surgery intervention .
  • the stapler is introduced into the abdomen via incision I , near the navel . Once inside the abdomen, the stapler is guided to the stomach .
  • Figures 2 and 3 schematically illustrate a surgical technique known as the SLEEVE GASTRECTOMY, which involves making a section line such that a portion of the stomach is removed . This intervention is further complicated by the need to remove a portion of the stomach from the patient .
  • Figure 4 shows an additional surgical technique known as the MAGENSTRASSE/MILL GASTROPLASTY .
  • This technique involves the creation of a slot , or an opening, at the level of the gastric antrum approximately 5- 6 cm from the pylorus . This slot is necessary to allow a stapler blade to pass through the stomach completely . Once the blade has been inserted through the slot , the resection is made in one or two di f ferent directions . In particular, proceeding with the section towards the angle of His , the MAGENSTRASSE is completely isolated from the gastric body . This intervention is known as MAGENSTRASSE .
  • the mill is reduced, no longer antral but prepyloric, an intervention known as the LONG MAGENSTRASSE GASTROPLASTY ( as shown in Figure 3 ) .
  • This method also involves pyloric finger fracture , ef fectively turning the intervention into a true gastric bypass .
  • the method shown in Figure 4 although it does not involve the resection of part of the stomach, nevertheless entails an operating risk comparable to that of the SLEEVE GASTRECTOMY due to the extensive section edges .
  • Surgical techniques using known staplers of the type described above have the disadvantage of having to cause very extensive section edges or perform the complete removal of a portion of the stomach .
  • the extensive section lines (for example , those performed according to the operating methods shown in Figures 1 to 3 ) expose the patient to the risk of fistulas and haemorrhage .
  • gastric tube dilation which is responsible for the inef fectiveness of the surgery, with weight regain, may occur in the patient .
  • the method is also burdened by a very high percentage of gastroesophageal reflux disease , which is almost impossible to treat surgically .
  • non-negligible morbidity and mortality rates are associated with the above surgical techniques , especially when referred to the reasons for the intervention, which are often l inked to conditions that statistically may reduce li fe expectancy but are not disabling or a direct cause of possible short-term death .
  • the obj ect of the present invention is to provide a surgical instrument which allows a new bariatric surgery technique to be performed without involving the resection and/or dissection of the stomach .
  • FIG. 1 schematically shows a person ' s abdomen and some details of the stomach and stomach wall ;
  • FIG. 5 is a schematic view of a surgical instrument according to the present invention, in use ;
  • FIG. 6 to 9 are schematic views of examples of bariatric surgery techniques achievable with a surgical instrument according to the present invention.
  • FIG. 10A is a schematic view of a laparoscopic stapler comprising a surgical instrument according to the present invention
  • FIG. 10B is an exploded view of a surgical stapler group according to the present invention.
  • Figure I OC shows the surgical stapler group in Figure 10B in an operating configuration
  • FIG 11 is a schematic view of the surgical stapler group in Figure 10B in a further operating configuration
  • FIG. 12 shows a variant of a surgical stapler group according to the present invention.
  • FIG. 13 and 14 show a variant of a surgical stapler group according to the present invention in respective di f ferent operating configurations .
  • Figure 1 schematically shows the abdomen of a patient P indicating the positions (numbered with Roman numerals from I to V) of the incisions that are normally made during a bariatric surgery intervention .
  • the wall T of the stomach S is a thick tissue comprising three layers of muscle tissue , indicated by Tl , T2 and T3 , and a mucosa M rich in glands G .

  • the surgical instrument 1 is identi fied as a stapler .
