Clamps
|
| Acland clamps are appreciated worldwide for
microvascular surgery. they are light, simple, compact and
easy to apply with wide gripping surfaces, which spread
the closing pressure uniformly across small, delicate
vessels, avoiding harmful crushing and slipping of the
vessels. A safety-stop avoids overstressing of the clamp
spring. |
|
|
|
Each clamp size is available in 3 different types:
-single clamp
-double clamp with approximator
-double clamp with approximator and frame |
| We recommend the approximator with frame
for almost all end-to-end anastomosis, particularly when
operating without assistance. |
| The approximator without frame is used when
the presence of an assistant makes a frame unnecessary, or
when the available apace does not allow the use of a
frame. |
|
|
"A" and
"V" Pattern Clamps |
| Clamps are available in "A" and
"V" pattern. The difference between the two
patterns is the inward curvature of the jaws near the very
tip of the "A" clamp. This modification
eliminates the sliding out of thick-walled arteries.
"V" clamps have perfectly flat jaws. |

|
Clamps for
Clinical Work |
| We recommend "A" clamps for
arteries and "V" clamps for veins in lower
extremities. |
|
|
Clamps for Animal
Work |
Rats and rabbits have very thin-walled
arteries, so "A" clamps should not be used. In
this case "V" clamps are suitable for both
arteries and veins.
Dogs have thicker-walled arteries, so that "A"
and "V" clamps are recommended. |

|
Clamp sizes
|
| Each clamp size works best over a
particular range of vessel sizes, as indicated below.
"Vessel size" refers to the external diameter of
the dilated vessel. |
| Clamp
Size |
Length |
Vessel
Size |
| C-1 |
8mm |
0.3-0.8mm |
| C-2 |
11mm |
0.7-1.5mm |
| C-3 |
14mm |
1.0-2.2mm |
| C-4 |
17mm |
2.0-3.5mm |
| C-5 |
25mm |
3.5-5.0mm |
These data also apply to the
corresponding double clamps.

Care of Clamps |
| During the operation do not allow blood to
dry on the clamps. Immediately after use, the clamps should
be immersed in cleaning solution for 30 minutes. Hold the
immersed clamp open for a while to wet the inner surfaces.
Move approximator clamps laterally a few times. Rinse well
with a fine jet of distilled water to remove all blood
residues. Dry the clamps immediately. |
