A surgical kit includes a surgical stapling device and a loading assembly. The surgical stapling device includes a tool assembly and a buttress material. The tool assembly includes first and second jaw members. The first jaw member supports a staple cartridge that includes a retention assembly. The retention assembly includes a cam block including a pair of protrusions and a spring biasing the cam block towards the second jaw member. The buttress material includes proximal and distal portions. The proximal portion defines bores laterally spaced apart and configured to receive the pair of protrusions of the cam block. The distal portion defines a cavity to be placed over a distal end portion of the staple cartridge. The loading assembly includes a housing defining a chamber configured to receive a portion of the buttress material. The housing includes a proximal portion defining a slot configured to receive the buttress material therethrough and the pair of protrusions of the cam block.

Methods for forming an implantable layer onto a staple cartridge are disclosed.

Devices for removing implanted objects from body vessels are provided. A device includes a sheath assembly having a cutting tip. The cutting tip includes a cutting surface that is adapted to cut tissue coupled to an implanted object as the cutting tip rotates. The sheath assembly further includes an outer shield carried outside of the cutting tip. The outer shield includes a distal opening, and the outer shield is translatable relative to the cutting tip from a first position to a second position and vice versa. In the first position the cutting surface of the cutting tip is disposed within the outer shield, and in the second position the cutting tip extends through the distal opening and the cutting surface is at least partially disposed outside of the outer shield.

A modular screw assembly for use in stabilizing a spinal column. The assembly has a fastener which couples to a screw head of a bone anchor, a screw head coupler, a retaining ring, and a friction ring. The fastener houses the screw head coupler, the retaining ring, and the friction ring. Translation of the fastener by the screw head results in the retaining ring elastically deforming and then snapping around the screw head.

A tool for installing and/or removing a protective cover of an instrument includes a body portion having an open end and a closed end. The open end defines an interior passage that extends into the body portion along a longitudinal axis of the body portion toward the closed end of the body portion. The interior passage is configured to receive at least a portion of the protective cover in the interior passage. One or more members are connected to the body portion, and each of the one or more members includes a free end movable relative to the body portion. Systems and methods relate to tools for installing and/or removing protective covers of instruments.

In a handle unit for interventional procedure, a master device for interventional procedure, and a remote control interventional procedure system, the handle unit is gripped by an operator. The handle unit includes a gripper, a mode selection module and a linear motion module. The gripper is gripped by the operator. The mode selection module is equipped to the gripper, and selects one of motion modes including a linear motion mode, a rotational motion mode and a plane motion mode. The needle linearly moves with one degree of freedom in the linear motion mode. The needle rotationally moves with two degrees of freedom in the rotational motion mode. The needle moves in a plane with two degrees of freedom in the plane motion mode. The linear motion module performs the linear motion of the needle based on the selection of the mode selection module, and is equipped to the gripper.

Disclosed is a portable multifunctional oral cavity cleaner which includes a tongue scraper, a material storage bottle, a material spraying device and a detachable housing; the tongue scraper can be changed into a contracted state from a stretched state via bending, rotating or folding, so as to reduce the volume of the oral cavity cleaner; an oral cavity cleaner body including the tongue scraper in the contracted state is housed in an inner cavity of the housing; and the housing can be reversely combined at the bottom of the oral cavity cleaner after being detached and used as a handle for prolonging the length of the oral cavity cleaner. The present application, featured with small size, light weight and portability, ensures hygiene in the carrying process and realizes multiple functions such as tongue coating removal, oral spray sterilization and interdental cleaning at one time.

A bone material dispensing device is provided. The bone material dispensing device comprises a housing having a proximal end, a distal end, and a longitudinal axis. The proximal end has a first opening and the distal end has a second opening. The first opening and the second opening are configured to slidably receive at least a portion of a plunger. A tubular member is provided that is pivotably connected to the housing and is configured for lateral movement relative to the longitudinal axis of the housing. The tubular member comprises a proximal opening, a distal opening and a channel disposed therebetween. The proximal opening, the distal opening and the channel of the tubular member are configured to receive at least the portion of the plunger. The tubular member is movable in a first position to align the proximal opening of the tubular member with the second opening of the housing to allow the tubular member to receive at least the portion of the plunger to dispense the bone material. A method of implanting bone material with the bone material dispensing device is also provided.

A cartridge assembly of a surgical stapling instrument includes a housing having an arcuate configuration, a knife disposed within the housing, and a staple actuator configured to eject staples. A longitudinally-extending cutting edge of the knife is configured to advance through tissue after the staple actuator ejects all of the staples from the cartridge assembly.

A surgical occluding device includes a body portion configured to radially surround a tissue lumen. The body portion includes a plurality of segments and a plurality of folds. Each fold of the plurality of folds is defined between adjacent segments of the plurality of segments. Half of the folds of the plurality of folds define acute angles, and half of the folds of the plurality of folds define obtuse angles. The body portion is movable from a first orientation where the acute angle defines a first acute angle, to a second orientation where the acute angle defines a second, smaller acute angle.
