BACKGROUND: Hospitals in low resource settings (LRS) can benefit from modern laparoscopic methodologies. However, cleaning, maintenance and costs requirements play a stronger role while training and technology are less available. Steerable laparoscopic instruments have additional requirements in these settings and need extra identified adaptations in their design. METHOD: Several modular detachability and tip steerability features were applied to the SATA-LRS instrument platform designed specifically for LRS. Ten subjects participated a dis- and reassembly experiment to validate the modularity, and in a steering experiment using a custom made set-up to validate steering. RESULTS: A new steerable SATA-LRS instrument was developed with the ability to exchange end-effectors through a disassembly of the shafts. Experiments showed an average 34 and 90 s for complete dis- and reassembly, respectively. Participants were able to handle the instrument independently after a single demonstration and 4 rounds of repetitions. Precise tip-target alignment in the box set-up showed a very short learning-curve of 6 repetitions. CONCLUSION: A novel instrument platform with articulating and rotating end-effector was designed for LRS. Within a minute the SATA-LRS can be disassembled to component level for inspection, cleaning, maintenance and repair, and can be autonomously reassembled by novices after a minimal training. The modular buildup is expected to reduce purchasing and repair costs. The instrument has been shown intuitive by use without extensive training. The experimental part of the paper was very detailed, including the reaction process of 2,5-Dioxopyrrolidin-1-yl 2-(acetylthio)acetate(cas: 76931-93-6Recommanded Product: 2,5-Dioxopyrrolidin-1-yl 2-(acetylthio)acetate)
2,5-Dioxopyrrolidin-1-yl 2-(acetylthio)acetate(cas: 76931-93-6) belongs to pyrrolidine. Pyrrolidine being a good nucleophile easily undergoes electrophilic substitution reactions with different electrophiles such alkyl halides and acyl halides, and forms N-substituted pyrrolidines. N-Alkylpyrrolidine on further reaction with alkyl halide provided quaternary salts.Recommanded Product: 2,5-Dioxopyrrolidin-1-yl 2-(acetylthio)acetate
