This disclosure relates to a medical device. The medical device comprises a first and a second component. The first component comprises a first portion having a first handle part and a second portion having a grip. The second component is linked to the first component and is configured to be in communication with the first component to be actuated from an open to a closed position. The second component defines a third portion and a fourth portion, the third portion defining a second handle part and the fourth portion defining a second grip that is configured to grip a tissue in combination with the first grip portion of the first component. In certain embodiments, the first component or second component comprises a substantially straight member attached distally from the grip.

An electrosurgical forceps includes first and second shaft members pivotably coupled to one another such that pivoting of the first and second shaft members between spaced-apart and approximated positions pivots jaw members thereof between open and closed positions. A proximal end portion of the second shaft member may be pivoted against a resilient bias of a spring element to apply a predetermined clamping pressure on tissue and ultimately engage an activation switch to delivery electrosurgical energy to the clamped tissue.

An electrocautery unit for connecting to a handle of an electrocautery device, the unit comprises a body, a light unit and an electrode. The body has a body proximal end and a body distal end, and a body axis extending lengthwise along the center of the body. The body’s proximal end comprises a connecting element for connecting said body to a handle having a handle axis extending lengthwise along the center of the handle, so that said body axis is coaxial with said handle axis when said body is connected to said handle. The light unit may be constructed and arranged to emit a light having a central axis coaxial with said body axis. The electrode comprises a proximate end connected to the body distal end, and an electrode tip at a distal said. When the electrode is connected to the body, the electrode lays outside of the body axis and extends into said body axis such that the electrode tip is within said body axis, wherein said light and said electrode tip are coaxial to said body axis and said handle axis.

Disclosed is a console for operating an actuating mechanism, relating to the technical filed of automatic control, and being for use in resolving the technical problem of shift of a controller under the influence of gravity. The console for operating an actuating mechanism includes a controller and a support base. The controller is constrained in both the longitudinal direction and the vertical direction, so that connection between the controller and the support base is tight and reliable, and no displacement would occur in any of three directions (i.e., the longitudinal direction, the horizontal direction, and the vertical direction). Thus, the phenomenon that position information given by the controller is inaccurate due to shift of the controller under the influence of the gravity after long-term usage can be avoided, thereby removing the factors affecting success of surgery, and ensuring the success rate of the surgery.

An end effector assembly suitable for use with a forceps includes opposing first and second jaw members pivotably mounted with respect to one another. The first jaw member includes one or more pivot holes defined therein configured to receive a portion of a pivot pin therein. The end effector assembly also includes an electrically-insulative hinge configured to electrically isolate the first and second jaw members from one another including one or more pivot-hole locators having an aperture defined therein. The electrically-insulative hinge is attached to the first jaw member such that the one or more pivot-hole locators align with the one or more pivot holes of the second jaw member.

A medical instrument comprising a device for activating or deactivating a function of the instrument. The device comprises first and second parts, which are each movable into an operative position relative to the other part to activate or deactivate a function of the instrument. A second control element for moving the second part into the operative position provides a control portion and comprises, for moving the first part into the operative position, a first control element which provides an additional control portion. The first control element can be moved in an opposite direction the direction from the second control element. Accordingly, the function is activated by moving a control element in a distal direction, and by moving another control element in a proximal direction. A deflection of force by one actuating element for actuating the first part or the second part in the opposite direction is not necessary.

A surgical gripping/holding instrument having two instrument branches which are coupled pivotably with respect to one another. Each branch has a distal gripping/holding portion, a proximal instrument actuating portion, and an intermediate region which connects the distal and proximal portions preferably integrally, and having an instrument lock, of which the locking elements which can be brought into latching engagement with one another are arranged or formed on the instrument branches. The actuation of the instrument for opening and closing is functionally separated from actuation of the instrument for locking and unlocking the instrument by the positioning of the instrument lock in the intermediate region of the instrument. Therefore, each actuation can be carried out individually.

The present disclosure discloses a control handle, which includes an outer clamp arm control mechanism and an inner clamp arm control mechanism. The outer clamp arm control mechanism may be configured to control the movement of an outer clamp arm of a tissue clamping device, and include a sleeve, a first control part, and a sliding part. The sliding part may be disposed in the sleeve. The first control part may rotate to drive the sliding part to move in the sleeve along a length direction of the sleeve, so as to control the opening and closing of the outer clamp arm. The inner clamp arm control mechanism may be configured to control the movement of an inner clamp arm of the tissue clamping device, and include a housing and a second control part. The second control part may pass through and move along a second sliding groove to control the opening and closing of the inner clamp arm relative to the outer clamp arm.

A forceps includes a pair of jaw members movable relative to one another, one of the jaw members defining a blade channel therein configured to house a cutting mechanism. The cutting mechanism includes: a blade having camming slots defined along a length thereof and one or more blade springs operably associated therewith configured to bias the blade within the blade channel; and a blade cam including camming surfaces configured to operably engage the corresponding camming slots of the blade. The blade cam includes a proximal end operably coupled to an actuation rod configured to move the blade cam upon movement thereof. The actuation rod, upon movement thereof, moves the camming surfaces of the blade cam into engagement against the camming slots forcing the blade into the blade channel against the bias of the biasing spring to cut tissue therebetween.

A staple cartridge comprising a cartridge body comprising a longitudinal slot, a deck surface, and a plurality of staple cavities defined in the cartridge body is disclosed. The cartridge body further comprises a plurality of projections extending from the deck surface. A surface of each projection is flush with one of a proximal end wall and a distal end wall of each staple cavity. The staple cartridge further comprises staples removably stored in the staple cavities.
