外科器械之Surgical scissors

打算自己买一把好用点的通用型组织剪，搜了一下，发现我们常用的“组织剪”其实种类还挺多。从材料来分，有不锈钢、高碳不锈钢、钨碳钢（tungsten-carbine）以及钛合金；Supercut剪刀的刃部会有细齿，剪切的可以时候避免组织滑动。

Mayo scissors

这个是手术室最常见的。
Mayo scissors are heavy scissors that can be straight or curved. Straight Mayos are often called “Suture Scissors.”

Metzenbaum scissors

比Mayo更修长，尤其是刃部更窄，适合精细操作，不要用于剪线。
Metzenbaum scissors or “Metz” are used for fine dissection and cutting. They are most frequently slightly curved. A common mistake is to use Metzenbaums to cut suture, which dulls the scissors and renders then less useful for dissection.

Iris scissors

我们常说的“眼科剪”。
Iris scissors are even finer than Metzenbaums and are used for cutting fine structures. They are short, straight, and sharp.

Potts scissor

这个颌面外科基本没见过用的。
Potts scissors are angled and most frequently used for cutting into vascular structures, as in a venotomy or arteriotomy.

Tenotomy scissors

刃部尤其精细。
Tenotomy scissors are surgical scissors used to perform delicate surgery. They can be straight or curved, and blunt or sharp, depending upon necessity. This equipment can be used in many surgical specialties, in particular delicate operations in ophthalmic surgery, oral and maxillofacial surgery, or in neurosurgery.
