Mouse Crush -

High-end gaming mice are often (sometimes under 60 grams) to allow for faster movement. Ironically, this makes them even more susceptible to being "crushed" compared to the heavy, clunky office mice of the early 2000s. 4. How to Prevent the Crush

Animal Preparation : Adult C57BL/6 mice (20–30 g) are anesthetized with isoflurane. Under aseptic conditions, the sciatic nerve is exposed at the mid-thigh level. Crush Instrument : A standardized crush is applied using fine jeweler’s forceps (No. 5 Dumont) or a non-serrated hemostat clamped to a fixed pressure (e.g., 40 N for 30 seconds). More advanced protocols use a calibrated pneumatic device to ensure reproducibility. Marking the Lesion : To track regeneration, the crush site is often marked with a 10-0 epineurial suture or fluorescent dye. Post-operative Care : Mice are monitored for autotomy (self-mutilation) and housed on soft bedding. mouse crush
