Featured I've got another one. This time a needlework tool?

This is a sewing or needlework punch of some kind. I know that much. But, is it a certain type of punch? It's even numbered, which I assume is for the size. And it's pretty long for a needlework punch, about 4" long overall.

Anyone know what it is?

 

for unpicking stitches .... a stitch unpicker

 

That is a lovely old tool!

 

Agatha Christie may have used it...

 

Surgical! Paracentesis needle (tympanic drainage)
https://www.collinmedical.fr/fr/consultation-en-otologie/3201-aiguille-a-paracentese-adulte.html

 

Spot On, kyra!

 

A paracentesis is when a needle is inserted into the peritoneal cavity (abdomen) to drain fluid that has accumulated.

Tympanic refers to the eardrum & you would never want an instrument such as this anywhere near your ear drum.

They do drain fluid that collects behind the ear drum mostly in children who have frequent ear infections. To do this they make a very tiny slit in the drum with a surgical blade & then place a tiny tube into the incision.

This allows for a way for the fluid to get out & the tubes will at some point fall out on their own.

 

The one on the link I posted is from a surgical instrument maker firm, is in the otological department, and is specified "adult paracentesis needle"

 

And this is why I am not in the medical field.

 

Paracentesis is performed with instruments called Trocars. Most that I found had this type of device as the center part of a drainage tool. The other part being a hollow tube. But finding the following picture of the case for a trocar looks pretty convincing.

Thank you! You set me in the right direction.

Thank you everyone. The discussions in these threads really helps me identify things.

 

That is confusing.

This type of trocar would not be used today unless you are in some remote area where modern things are not available.

The trocars they use now are all disposable mainly because the reusable ones were very difficult to clean. They also were just a very big sharp nail inside a tube that if you weren't careful could poke a hole in something very vital.

The late 1980s was also when laparoscopy surgery started to expand to include more surgeries such as gall bladder surgery. The disposable ones came with a safety feature that once the peritoneal cavity was penetrated a plastic guard would cover the end of the trocar thereby helping to prevent injury.

 

Is vintagerobins instrument hollow ?

because trocars are for puncturing or , nowdays, inserting a canular

https://en.wikipedia.org/wiki/Trocar



which is possible why this was found in a sewing kit and not a medecine chest

 

It isn't hollow.

 

I've been getting this done about every 5 years for half a century.
Excellent explanation!

 

I circulated for countless BM&T's (Bilateral Myringotomy & Tubes) in my years in the OR. Usually, the hardest part of my job was when they put the mask over the child's face who was sometimes under 2 years old & you basically had to throw yourself on top of the child to keep them from taking a nosedive off the OR bed.

 

[QUOTE="vintagerobin, It isn't hollow.[/QUOTE]

if its not hollow ..... how can you drain anything ?

 

stick it in.......pull it out......

 

Bless you!
I was 11yo my first time... I remember it involved general anesthesia and a two night stay in the hospital. Now, it's three minutes in the office with only a quick spray of a local anesthetic on the eardrum.
