Here it is in close up. Turn needle through tissue. Then either push through a bit, or pull through from the other side. Practice grabbing needle on other side so it is ready to go for the next bite. Economy of movement. Remember to turn through curvature of needle. 2/5

Free-Hand Suturing—Control of the Arm, Hand, and Fingers🕊️ 👉In deep or restricted operative fields, there may be no place to rest the arm or hand, requiring precise suturing while keeping the upper limb suspended. 👉Accurate needle handling depends on coordinated control of the arm, hand, and fingers even without a fixed resting point.

From #SevenBypasses: “Infinitesimal forces drive the needle forward and the wall backward, the needlepoint pierces the tissue with a haptic “pop” that transmits through the instruments, fires the fingertips’ sensory receptors, and stimulates the faintest of perception of a bite. The needle glides through the tissue until the driver meets the microforceps to fully consume the bite. The microforceps then exits the arterial lumen, gently lifts the second wall with its fine tips, and the cycle repeats. Another collision of infinitesimal forces and another haptic pop as the needle pierces and glides and bites. With a squeeze of the microforceps and a release of the driver, the driver circles around to counter-sweep the tissue off the back end of the needle and the needle completes its bite...”

Jet injectors were used for mass vaccination, and as an alternative to needle syringes. The devices used compressed air to deliver vaccines, forcing the liquid through the skin without a needle; the jet injector was widely hailed as "the peace gun."

Jet injectors were widely used for mass vaccination campaigns as a needle-free alternative. Powered by compressed air, these devices forced the vaccine through the skin without a needle and were popularly hailed as “the peace gun.” Why were they discontinued?

VIDEO | Doctors of a private hospital in Tamil Nadu's Thanjavur have set a record by removing a four-cm-long needle from a 14-year-old girl's lung without using a knife in three and a half minutes. The girl had swallowed the needle while dressing. Doctors of the hospital used a modern technology called Bronchoscopy to remove the needle. (Full video available on PTI Videos -

💉 Pulley injection — why the short-axis approach? The short-axis approach offers a simple but important advantage: continuous visualization of the digital neurovascular bundles throughout the procedure, allowing precise and controlled needle placement. Another useful trick: when the goal is injection rather than pulley release, adjacent symptomatic pulleys—or any contiguous structure—can be treated through a single skin entry point, redirecting the needle under ultrasound guidance, as shown in the video. One entry. Two pulleys—or any contiguous structure. Full control. 🎯

One ordinary silver needle. Hair thin. Almost invisible, She holds it between her fingers like it’s nothing then gives it the tiniest flick. In a single heartbeat, that one needle splits into three sharp, deadly, and perfectly controlled. No grand gestures. No loud words. Just pure, terrifying precision.

One of my favorite needle drops of all-time is D’Angelo’s “Sh*t, Damn, Motherf*cker” in The Best Man. The perfect track for when Lance put two and two together.

Weaving nail art? Yes, it looks incredibly unique, but using a needle that close to the skin? One wrong move and it’s a disaster. Would you risk it for the aesthetic?

Surgical Simulation—From Basic Skills to Procedure-Specific Practice🎥 👉Repetitive practice of fundamental skills—needle handling, suture placement, and knot tying—builds the precision and economy of motion required in cardiac surgery. 👉Procedure-specific models, such as VSD patch closure, allow these basic skills to be integrated into a realistic operative sequence before performing them in the operating room.

whenever the subject of "best needle drops" comes up, i rarely see this one mentioned. though it is undoubtedly top-tier; a number as stupid, and energizing, as the film.
