Shabbat 123B

אפיקטויזין בשבת. ורב ששת: התם ⁠— לאו אורחיה, הכא ⁠— אורחיה.

afiktoizin, a drug to induce vomiting, on Shabbat. Apparently, actions associated with treating the body on Shabbat are prohibited. And Rav Sheshet explains: There, with regard to a drug to induce vomiting, drinking it for any reason other than medicinal purposes is atypical. Here, aligning the limbs of an infant is typical conduct not undertaken solely for medicinal purposes.

אמר רב ששת: מנא אמינא לה ⁠— דתנן: מחט של יד ⁠— ליטול בה את הקוץ! ורב נחמן: התם ⁠— פקיד, הכא ⁠— לא פקיד.

Rav Sheshet said: From where do I say that this is the halakha? As we learned in the Mishnah: One is permitted to take an ordinary hand needle used for sewing clothes to extract a thorn with it. Apparently, some curative actions are permitted and there is no concern that they are similar to completing the production process of a vessel. And Rav Naḥman objects: That is no proof, as there, the thorn is merely deposited in the skin and it is not an organic part of the body. Removing a foreign object from the body effects no fundamental change in the body. Here, in the case of aligning the limbs, it is not merely tending to a foreign object deposited in the body; rather it involves effecting a fundamental change in the body itself, which is both a curative act and one similar to completing the production process.

מתני׳ קנה של זיתים, אם יש קשר בראשו ⁠— מקבל טומאה, ואם לאו ⁠— אין מקבל טומאה. בין כך ובין כך ⁠— ניטל בשבת.

Mishnah: A reed that is used for turning olives in a bundle, if there is a cork-like knot at the top of it, it can become ritually impure as a vessel, and if not, it cannot become ritually impure, because it is not a vessel. In either case, it may be moved on Shabbat for use in a permitted action.
