A surgical clamp assembly includes a clamp having movable jaws, each of which has a clamping surface for engaging a portion of a patient's body. An electrode forms a portion of the clamping surface of at least one of the jaws, the electrode being capable of heating, severing, or cauterizing the portion of the patient's body that is grasped by the clamp. If desired, the clamp assembly can be provided with a retainer that prevents the jaws from being opened accidently. The clamp assembly also can include an actuator that can be detached from the clamp and removed from the operative site, leaving the locked clamp in place. In this type of assembly, when it is desired to remove the clamp, the actuator can be reattached to the clamp and used to disengage the toothed retainer, and thereafter can be used to spread the jaws in order to permit the clamp to be removed.

A surgical clamp includes opposing jaws and a covering enhancing traction between the jaws and a body conduit. A multiplicity of fibers oriented to extend longitudinally between the clamp and conduit may be composed of filaments and either woven or non-woven to form a fabric. A variety of weaves are contemplated to provide different textures, each having its own traction characteristics. The nature of the weave can control characteristics such as smoothness, absorption, and texture. The fibers or filaments may be formed from any solid or semi-solid material, adding its own characteristics to the resulting fabric insert or clamp.

The invention concerns a clamp, especially a surgical clamp, with a left clamp half to receive a left half of a breastbone during a surgical procedure, a right clamp half to receive a right half of the breastbone, as well as a first toothed rod and a detent mechanism engaging in the first toothed rod to secure the left clamp half at a distance from the right clamp half, wherein the detent mechanism engaging in the first toothed rod has a detent region extending at least from the left clamp half to the right clamp half.

The present invention generally provides a surgical clamp for use with a surgical retractor support frame. The surgical clamp has a handle that rotates about a first pivot point from a first position to a second position, and a second pivot point eccentric to the first pivot point. The surgical clamp also has an intermediate link with a first portion that rotates about the second pivot point and a second portion that is rotatably connected to a third pivot point on an output link. The intermediate link is manipulated by rotation of the handle, and the intermediate link further manipulates the output link from a first position to a second position. The output link is operably connected to at least one of the first and second clamps to apply a clamping force on a surgical instrument to lock the surgical instrument in place.

An ultrasonic surgical clamp coagulator apparatus is configured to effect cutting, coagulation and clamping of tissue by cooperation of a clamping mechanism of the apparatus with an associated ultrasonic end-effector. The clamping mechanism includes a pivotal clamp arm, which cooperates with the end-effector for gripping tissue. The clamp arm is provided with a clamp tissue pad that has at least one raised portion to achieve the desired cutting and coagulation effect on the tissue.

Opposable surgical clamp members having opposable resilient pads with wedge-shaped and cylindrical protrusions extending from the surfaces of the pads and the use of such members for occluding vessels and other tubular body structures are described. The protrusions are arranged such that when the members are moved toward one another, the protrusions of one pad interdigitate with the protrusions of the other pad. Upon engagement with a vessel, portions of the vessel are forced into the interdigital spaces providing for improved gripping of the vessel. The protrusions also resist lateral or transverse movement of a clamped vessel relative to the pads. The existence of through holes under the pad surface alters the relative resiliency of the pad, allowing for an overall pad resiliency that minimizes trauma to a clamped vessel while allowing the local resiliency of the protrusions themselves to be of a hardness to avoid excessive deflection and retain the desired shape and gripping ability.

A surgical clamp is provided that is applied through a laparoscopic port and is used for clamping off a portion of an organ. The surgical clamp comprises an elongated flexible bioabsorbable polymer band laced with a hemostatic agent. The band has a proximal end and a distal end. A bioabsorbable polymer tie secures in place the proximal end of the band to the distal end of the band. A conductive wire snare is provided to cut and cauterize a target.

The invention relates to a medical surgical clamp matched with an endoscope, in particular to a visible surgical clamp with an endoscope sheath used for taking the intrauterine device out from the uterus. The existing visible surgical clamp is used in the birth control surgery, for example in the surgery to take the intrauterine device out from the uterus with the endoscope. Due to the easy bleeding of the endometrium tissue, the lens of the endoscope is easily contaminated to dim the surgery view, and the device is inserted in and taken out repeatedly for flashing, therefore the surgery time is prolonged and the operation is complicated. After the improvement, the groove formed after the side by side arrangement of the endoscope sheath and the drive rod is also fixed with two flush pipes 15 and 17, wherein the open of one flush pipe faces the open of the endoscope sheath 10, and the open of the other flush pipe faces a clamp head 6. A surgical cannula is provided, and the water nozzle on the surgical cannula is communicated with a negative pressure source to absorb and remove the water of flushing. The improved surgical clamp provides clear surgery view, has compact integral structure and convenient operation, and can shorten the surgery time.
