I have found the Pilot Kakuno (about ¥1000, so inexpensive) - just IMO, - pilot ink is very easy flowing, the nibs are great for my writing style, pull off cap not screw, so much easier and readier to use, easy to clean. I work in the UK health service which is not a good place for stationery lovers.

"Example: My wife is in surgery, and has told me how surgical tools often come billed as a set. Rather than being able to bill for a single tool, if an operation requires another duplicate of the same tool the surgeon will often just open an entire new set." That could be because the instrument required has been sterilised as part of a set and is not sterilised individually. This is a common problem in the UK where I work (as a surgeon), - the logistics of individually tracking all single packaged instruments would be unworkable and hugely costly.So they are grouped as a set for a particular operation.

(Not remotely competing) neurosurgeon here. Vision never ceases to amaze me in its robustness. Patients with long-standing (years) visual field defect from pituitary tumour will recover their vision within minutes of it being decompressed. One of the most satisfying things I do is ask the patient in the recovery area if they can see the time on the clock opposite them, - the operation having finished 30 mins ago. Most can, - this says much more about nature, nerve compression and neuronal plasticity than the surgery.

Yes, tho they have been around now for about 20y, are big (no good for eg neurosurgery, ent) and cost $2m. You don't need that for lap appendicectomy, - just a better scope, and a good surgeon. Robots have no advantage over human dexterity. They have a few niche roles eg where we can't get our hands in eg the prostate.

Noted. What has been stable for a long time and remains frustratingly static and unrefined is the field of surgcial instruments. There are a few exceptions but most haven't changed in the 20years I have been a surgeon. The regulatory costs of developing new instruments and intertia of manufacturers doesnt help. Once a manufacturer gains a market share they try and keep by not innovating which keeps their deveopment costs down and the consumer volume is comparatively low. I don't get the feeling there is any sense of patient altruism. I have been using the same 4mm dia endoscope 25cm long since 2007 when the first iphone came out. It is very simple, made of glass fibres with a sony 3chip camera that is 10y old. We get some v slow progression on video output and have just got 4k. Compared to consumer tech the advances are ridiculously slow. We need a camera (the iphone camera is small enough) on a steerable stick. How hard an engineering task can that be?.

Dueling Scar 6 years ago

The facial nerve is the 7th cranial nerve. It's branches innervate the muscles of facial expression. It is deep and it takes a deep cut to sever it's branches usually through muscle. Most of the scars are horizontal and I dont think I have seen one associated with a facial palsy.

Are these milliseconds? The visual evoked response latency ( time taken from the eye to electrical activity in the occipital cortex ) is about 88 ms in Women and 92 ms in men. There will be additional time for the visual object ( eg cursor) to be processed and appreciated in higher centres.
