An ambidextrous locking clamp system for providing a user the ability to use the right or left hand to engage and disengage a ratcheting means on the clamp. The clamp includes hingedly connected first and second elongated members each with a finger engaging member, a working head, and a latching member featuring ratcheting teeth. The teeth are engaged by moving the finger engaging members toward each other in an engaging motion, and are disengaged by sliding them in a disengaging motion perpendicular to the engaging motion with opposing force applied to the finger engaging members. One of the elongated members includes a planar portion that is rotatably received in a slot defined in a female portion of the other elongated member. The planar portion can include a wedge that contacts a side of the female portion that defines the slot when the clamp is in a closed position.

The present disclosure is directed to a medical instrument. The medical instrument may include a delivery device and a retraction mechanism including a target tissue anchor and a first stabilizing anchor, wherein the target tissue anchor attaches to target tissue and connects to the delivery device.

An ambidextrous locking clamp system for providing a user the ability to use the right or left hand to engage and disengage a ratcheting means on the clamp. The clamp has hingedly connected first and second elongated members each with a finger engaging member arm, a finger engaging member, a working head, and a latching member featuring ratcheting teeth. The teeth face each other in a direction parallel with a longitudinal axis of the clamp. The teeth are engaged by moving the finger engaging members toward each other in an engaging motion, and are disengaged by sliding them in a disengaging motion perpendicular to the engaging motion with opposing force applied to the finger engaging members. A space is defined between the finger engaging member arms and the finger engaging members. The latching members extend into the space from where the finger engaging members transition from their corresponding finger engaging member arms.

An energy-based surgical device includes an elongated outer tube having a distal overhang, a proximal hub, a distal cutting member, and a flat spring. The distal cutting member has a U-shaped cutting edge and defines a mouth with the distal overhang extending therethrough. The flat spring includes a first portion extending distally along an exterior surface of the elongated outer tube and the distal overhang, a second portion extending from the first portion and bent over a free distal end of the distal overhang, and a third portion extending from the second portion proximally through the mouth of the distal cutting member and into the lumen of the elongated outer tube and traverses a majority of a diameter thereof. The distal cutting member and flat spring are adapted to connect to a source for electrosurgical energy for conducting bipolar energy through tissue disposed therebetween to cut tissue.

A surgical clamp jaw is disclosed, having an inner profile and a deflection control profile opposite the inner profile. In one embodiment, the inner profile has a first substantially concave profile in an unclamped position and a second substantially flat profile in a clamped position. In one embodiment, the deflection control profile has one or more sets of corresponding abutment surfaces, at least one set of which is not contacting each other when the inner profile is in the unclamped position and which is contacting each other when the inner profile is in the clamped position. In one embodiment, the surgical clamp jaw defines one or more flexion assistance voids, wherein at least one of the one or more flexion assistance voids is in contact with a gap between one of the one or more sets of corresponding abutment surfaces.

Methods and apparatus for end effector control and calibration are described. The method may include detecting a signal in response to movement of a first tube relative to a second tube, the first tube driving movement of a clamp arm of the end effector. The method may further include determining a clamp arm position of the end effector relative to a ultrasonic blade of the end effector based on the signal. The method may also include adjusting a power output to the ultrasonic blade of the end effector based on the clamp arm position.

A surgical instrument includes a female instrument part that defines a hollow volume in a coupling region and a male instrument part that forms a guide section in the coupling region. The guide section is configured to at least partially pass through the hollow volume. A pivoting element, which has an upper section, a center section, and a lower section, couples the female instrument part and the male instrument part to each other in such a way that the female instrument part and male instrument part can pivot relative to each other about an axis of rotation of the pivoting element. A lateral upper contact step is formed between the upper section and the center section of the pivoting element and a lateral lower contact step is formed between the lower section and the center section of the pivoting element.

Surgical tissue fusion instrument having two gripping structures which are movable relative to each other, are designed for gripping and bringing together biological tissue sections, and are assigned heat-generating means designed in such a way that tissue fusion takes place between the biological tissue sections by heat being supplied in the area of the gripping structures. At least one gripping structure is assigned a fluid-conducting system, which is designed to supply at least one liquid or flowable additive to the tissue sections during a tissue fusion process.

A vascular catheter wire clamp is provided. The vascular catheter clamp includes an elastic body, a clamping shaft, and a clamping shaft receiving passageway. The elastic body includes a first arm having a first retention surface, a second arm having a second retention surface, and a bent section connecting the first arm and the second arm such that first arm away from the bent section and parallel with the second arm. The clamping shaft extends inward from outward facing surface of the first arm and includes a retention member positioned along an end thereof. The clamping shaft receiving passageway is positioned through the second arm and corresponds with the clamping shaft and the retention member.

A surgical clamping device includes a handgrip, an actuation assembly, an elongated body portion, an upper jaw assembly, and a lower jaw assembly. Each of the upper and lower jaw assemblies includes and an elongated jaw body and a distal clamping portion that is supported on a distal end of a respective elongated jaw body. Each of the elongated jaw bodies includes a proximal end that is pivotally connected to the actuation assembly by a pivot member located within the handgrip. The pivot member is spaced from the distal clamping portions of the upper and lower jaw assemblies such that the distal clamping portions of the upper and lower jaw assemblies remain substantially parallel as the upper and lower jaw assemblies are pivoted between open and clamped positions.
