The present disclosure is directed to an inflatable-cushion inflation and sealing device. The device includes an inflation assembly configured for insertion between first and second overlapping film plies. The inflation assembly includes a fluid conduit configured to direct a fluid in between the plies to form one or more cushions. The fluid conduit includes a nozzle. The inflation assembly includes a cutting member. The cutting member includes a blade holder with a blade and a blade guard mounted thereon. The blade guard has a safety position in which the blade is covered and a retracted position in which the blade is exposed. Installation of the blade holder onto the inflation assembly automatically positions the blade in the working position with the blade guard retracted. Removing the tray from the inflation assembly automatically positions the blade in the safety position by covering the blade with the blade guard.

A forceps includes an end effector assembly having first and second jaw members movable between a spaced-apart position and an approximated position for grasping tissue therebetween. A knife assembly having a cutting blade disposed at a distal end thereof is also provided. The knife assembly is translatable relative to the end effector assembly between a retracted position and an extended position, wherein the cutting blade extends between the jaw members to cut tissue grasped therebetween. The knife assembly includes a proximal component and a first distal component that includes the cutting blade. The proximal and first distal components are removably coupled to one another to facilitate replacement of the first distal component. Methods of preparing such forceps for reuse are also provided.

The present disclosure provides a dual-blade tendon cutting apparatus and cartridge for multiple apparatuses. Exemplary aspects of the present disclosure relate to a cutting implement that comprises two parallel blades that are spaced apart from one another by a predefined distance. The distance between the blades determines a lateral size of a graft being taken from the quadriceps tendon. To simplify matters for the surgeon, a cartridge is provided with three different blade sets. Much like a razor that has a disposable head, the cutting implement may attach to a desired blade set and be used.

A knife cartridge for use in a surgical instrument. The knife cartridge includes a blade that can be operated by a second operating element. The blade is held in a blade housing that can be transferred from a first locking position (passive position) into a second locking position (active position) by a first operating element. In the passive position the blade housing is completely located inside the cartridge housing and the blade is locked therein. In the active position the blade housing projects out of the cartridge housing. Only in the active position a locking between the blade housing and blade can be released, whereby also only then a driving connection is established between the second operating element and the blade.

Disclosed herein are apparatuses, systems, kits, and methods for treating skin, such as skin tightening or for treating diseases, disorders, and conditions that would benefit from tissue area or volume reduction, skin restoration, skin tightening, skin lifting, and/or skin repositioning and/or for generally improving skin function or appearance (e.g., the removal of unwanted skin features or irregularities such as sebaceous glands, sweat glands, hair follicles, necrosis, and fibrosis). Such apparatuses, systems, kits, and methods comprise an apparatus having a handheld main body and a detachably attachable tip comprising one or more needles.

A utility tool device including a handle with a tool recess and a lever arm recess; a rotatable lever arm with a magnet that is configured to fit in the lever arm recess; and a rotatable lever hinge attached to the lever arm and configured to attach to a tool; wherein the tool recess is configured to have a tool fit in the tool recess; and wherein the magnet is configured to lock a tool in place when the lever arm is in the lever arm recess.

A safety scalpel is made of a blade shield, blade, blade holder and handle. The blade holder is located in the front portion of the handle and the blade holder and handle are of integral connection structure or separate plug type connection structure. The blade is fixed in the front portion of the blade holder and the blade shield is slidably mounted on the blade holder, wherein: the blade holder is provided with a first sliding channel and the first sliding channel is provided with a first front locking channel at its front end. A deadlock channel is set in front of the first front locking channel. The blade shield may be moved further forward after use to make the first protrusion of blade shield fall in deadlock channel to enter the deadlocking state. The construction thoroughly eliminates the safety problem of reusing scalpel.
