Talk:Trocar

Merriam-Webster definition is better than other link's. "Carre" is the edge of a sword or so. —Preceding unsigned comment added by 77.197.248.37 (talk) 00:40, 29 August 2009 (UTC)

First paragraph is unclear.

It is unclear what the word "this" is referring to in the first paragraph. —Preceding unsigned comment added by 205.170.75.154 (talk) 22:14, 17 June 2010 (UTC)

First paragraph is worse than unclear.

"A trocar ... is a medical device that is made up of an obturator (which may be a metal or plastic sharpened or non-bladed tip), a cannula (basically a hollow tube), and a seal"

Well obturator links to "(surgery) An object used to obstruct a hole, such as a fissure of the palate.".

So a trocar is defined as 'a seal (which may be sharpened metal or plastic), a tube and a seal', which makes little sense.

My best guess is that by obturator, what is meant is a seal that can be opened (but then the seal on the other end must be openable) once the sharp part has penetrated the skin (or whatever).

ː fixed ǃ replaced the "obturator" by "awl" which makes more sense ǃ--Uruk (talk) 13:00, 25 September 2020 (UTC)

The correct terminology is obturator. If you are unsure, do not edit. --42.200.221.66 (talk) 07:58, 28 December 2020 (UTC)

Whoever wrote the article (article) loved putting little explanations (like this) in brackets, which is both lazy (less effort than writing a new sentence) and hard to read (as you can tell (from reading this)). -Ashley Pomeroy (talk) 00:31, 17 March 2017 (UTC)

Two types - drain / vent ~ laparoscopy port

The article has been tagged for recentism - and the lede certainly has that problem, focusing on laparoscopy ports. But the older, drain type comes up at several points through the body of the article (though never really explicitly distinguished from the laparoscopy type). Trocars as currently used by embalmers are unlikely to be laparoscopy ports(!); and veterinary use as described seems to be mostly for drainage / venting.

So the broader problem is tht the article needs to be organised according to these two different types of instrument, laparoscopy trocars (informally, "ports") and the familiar / traditional drain / vent trocars.

It would also be worth distinguishing both (using [[ Template:For |({{For]] or its friends) from catheter ports.

Apologies: I've chattered above about laparoscopy, inadvertently omitting thoracoscopy. I meant endoscopy generally, of course.

I've now had a go at the lede for some of the changes I've suggested - but it'll need revisiting when the article body is organised to contrast, explicitly, drain/vent ~ endoscopy trocars.

Now also had a go at setting up a disambiguation hatnote, "Not to be confused with the implanted blood access device" (+ pair).

Not at all sure I've (eg) used the right template. Please feel free to fix!
