clamp - 1. any device used to grip, join, compress, or fasten parts.

2. a surgical instrument for effecting compression. See accompanying table and see also under forceps.



Cope clamp, a crushing clamp with several hinged segments for use in surgery of the colon and rectum.
cotton roll rubber dam clamp, a rubber dam clamp with a buccal and lingual wing or flange to hold cotton rolls in position in the mouth; useful in the placement of direct gold or other restorative material in subgingival class V cavity preparations.
Crile clamp, a rubber-shod clamp to secure temporary hemostasis in suture of blood vessels.
Doyen clamp, a forceps with flexible blades for clamping tissues to control bleeding temporarily during operations on the gastrointestinal tract.
Gant clamp, a right-angled clamp used in operating on hemorrhoids.
gingival clamp, a clamp for retracting gingival tissues.
Goldblatt clamp, a clamp for the renal artery to produce experimental hypertension; see also Goldblatt hypertension under hypertension and Goldblatt kidney, under kidney.
Joseph clamp, a clamp used after a nasal operation to improve the alignment of the mobilized fragments of the bony framework of the nose.
Mikulicz clamp, a clamp used for crushing the septum between the proximal and distal segments of the colon after exteriorization.
mosquito clamp, a small hemostatic clamp.
patch clamp, a type of voltage clamp in which a patch electrode is pressed against an area of the plasma membrane of a cell, forming an electrically tight seal so that the flow of current through individual ion channels can be measured.
Payr clamp, a crushing clamp used in resections of the stomach, intestine, and colon.
Péan clamp, a curved or straight hemostatic clamp with serrations along the entire length of the jaw.
pedicle clamp, clamp forceps (def. 1); see under forceps.
Potts clamp, an atraumatic clamp used to grasp a blood vessel.
Rankin clamp, a three-bladed clamp for crushing the colon during resection.
rubber dam clamp, a device made of spring metal that is used to retain a rubber dam on a tooth; it has beveled jaws that contact the tooth and a bow that connects the jaws.
Sehrt clamp, a clamp for compressing the aorta or for compressing a limb to arrest hemorrhage; called also Sehrt compressor.
voltage clamp, an electronic technique employing the feedback principle to impose a fixed potential difference across a cell membrane; used in the study of ion channels. Voltage across the membrane is fixed at a set level and the current changes to counterbalance any induced flow of ions; the current change is a measure of the change in conductance of the membrane for one or more specific ions.
