An instrument and method for tissue thermotherapy including an inductive heating means to generate a vapor phase media that is used for interstitial, intraluminal, intracavity or topical tissue treatment. In one method, the vapor phase media is propagated from a probe outlet to provide a controlled vapor-to-liquid phase change in an interface with tissue to thereby apply ablative thermal energy delivery.

A surgical stapler includes an anvil half and a cartridge half. The anvil half includes an anvil channel member and an anvil surface. The cartridge half releasably couples with the anvil half and includes a cartridge channel member having a distal portion that receives a staple cartridge, and a latching member coupled to the cartridge channel member and movable between open and closed positions. A resilient member is arranged at a proximal end of one of the anvil half or the cartridge half, and a projection is arranged at a proximal end of the other of the anvil half or the cartridge half. The resilient member is configured to contact and releasably couple with the projection to thereby couple the proximal end of the anvil half with the proximal end of the cartridge half while the latching member is in the open position.

Resected bone and/or tissue removal instruments and related methods are disclosed. The instruments include a first elongate member including a first head portion with a front edge and a first handle portion. The instrument further includes second elongate member rotatably coupled to the first elongate member at a first rotation point, the second member including a second handle portion and an end portion. The instrument also includes a third elongate member rotatably coupled to the first elongate member at a second rotation point, the third member including a second head portion and an end portion. The end portions of the second and third members are rotatably coupled at a third movable rotation point positioned between the first and second rotation points. The second head portion includes an interior surface with a front cutting tooth defining a free end of the second head portion.

The invention provides a pair of dual-purpose forceps, comprising a first forceps body and a second forceps body. When the first forceps body is connected with the second forceps body by means of a first pressurizing connecting member and a second pressurizing connecting member, a first handheld member and a second handheld member move towards each other, and a first pressurizing functional member and a second pressurizing functional member also move towards each other to complete pressurizing; when the first forceps body is connected with the second forceps body by means of a first opening connecting member and a second opening connecting member, the first handheld member and the second handheld member move towards each other, and a first opening function member and a second opening function portion face away from each other to complete opening. The dual-purpose forceps is simple in structure and is operated conveniently so that the double-purpose forceps can switch freely between opening and pressurizing functions conveniently and quickly.

An ultrasonic surgical instrument and method of assembly with a predetermined alignment includes first and second modular assemblies and an electrical lockout. The first modular assembly includes at least a portion of an end effector configured to manipulate a tissue. The second modular assembly includes a transducer power circuit and an activation switch electrically connected to the transducer power circuit. The electrical lockout is electrically connected to the transducer power circuit and configured to inhibit the activation switch from powering the ultrasonic transducer with the first and second modular assemblies misaligned from the predetermined alignment such that the first and second modular assemblies are in a locked-out state. The electrical lockout is further configured to allow the activation switch to power the ultrasonic transducer with the first and second modular assemblies in the predetermined alignment such that the first and second modular assemblies are in an operational state.

A forceps having at least a first jaw with a longitudinal axis is disclosed. The first jaw can include a body portion, a first flange, a second flange and a cam pin. The first flange can define a first cam slot with a longitudinal extent along the longitudinal axis. The second flange can be spaced from the first flange a distance transverse to the longitudinal axis of the first jaw and can have a second cam slot. The cam pin, with a longitudinal axis, can be moveably secured within the first cam slot and the second cam slot. A diameter of the cam pin can be less than a width between a first longitudinal edge that defines a first side of each of the first cam slot and the second cam slot and a second longitudinal edge that defines a second opposing side of each of the first cam slot and the second cam slot so that the cam pin is moveably received by both the first cam slot and the second cam slot. With the first jaw pivoted to at least a first position, the cam pin and first flange can be configured such that the first longitudinal edge is contacted by the cam pin but the second longitudinal edge is spaced from the cam pin. The cam pin and second flange can be configured such that the first longitudinal edge is spaced from the cam pin but the second longitudinal edge is contacted by the cam pin.

A surgical instrument has at least two individual components that are movable relative to one another, each comprising a sliding surface region, and jointly forming a sliding surface pair. The sliding surface regions abut one another in sliding surface region sections and slide on one another. Only one of the sliding surface regions of each sliding surface pair comprises a hard material surface layer which is materially bonded to the individual component in the respective sliding surface region. The sliding surfaces of the sliding surface region sections of each sliding surface pair have a distance of less than 0.05 mm and 0.025 mm from each other. In a sliding surface pair, the relative movement of the two individual components the sliding surface regions of which form this sliding surface pair takes place in mutually parallel planes of movement.

A surgical tool for separating two components, for example removing a femoral head from a femoral stem, having a four bar chain whose four bars are a first handle (L1), an crossover component (L2), a second handle (L3) and a crossbar (L4) pivotally connected respectively by: a first joint (J1) between the first handle and the crossover component; a second, crossover joint (J2) between the crossover component and the second handle; a third joint (J3) between the second handle and the crossbar, and a fourth joint (J4) between the crossbar and the first handle, and wherein, upon application of a gripping force to the first and second handles, the first and second jaws separate from one another so as to separate the two components engaged therewith.
