OneShot-M: A New Device for Close Laparoscopy Pneumoperitoneum

Abstract

The use of the proposed device showed an induction time as quick as the standard laparoscopic closed abdominal entry. The patented device is cheap and allows a safe abdominal entry. In addition, abdominal entry is much faster than the classic open technique.

Direct Trocar Insertion using an Abdominal Wall-Lifting Device in Laparoscopic Surgery: Pilot Study on Porcine Model

“…OneShot-M feasibility had already been successfully proven in 2018 in an experimental study on porcine model, for which the device was specially designed and created in order to allow the passage of a 15 cm-long Veress needle [35]. In that work, the self-made suction cup system allowed us to gain abdominal entry and pneumoperitoneum fast and securely in all procedures, without any intraoperative and postoperative complication linked to Veress needle technique.…”

“…According to the promising findings of this previous research [35], in the current study we evaluated OneShot-M performance applied to the DTI method. This goal required the necessary adjustment of the device structure from the aforementioned prototype, in order to create an access hole suitable for the introduction of a 5 mm-long trocar (Figure 1).…”

“…OneShot-M prototype configuration is described in Figure 1. Compared to the prototype used in the previous work [35], when the access hole was specially designed to allow Veress needle insertion, the suction cup device has been modified so that it could be crossed by a 5-mm trocar/cannula. Briefly, twenty-four hours before surgery, all animals started fasting.…”

“…In a previous work we evaluated and successfully tested in an in vivo animal model the feasibility, effectiveness, and safety of OneShot-M, a suction cup device that we designed and initially proposed for making Veress needle introduction secure, simple and speed [35]. In the effort to optimize the efficacy of DTI method, the current study aimed to report our experience in a porcine model using a prototype of OneShot-M modified in order to facilitate the direct positioning of the first trocar.…”
