A histology radius blade grossing knife is provided. The histology radius blade grossing knife has a blade mounting system adapted to operatively retain a histology radius trimming blade. The blade mounting system provides a retaining spine for engaging an upper edge of the trimming blade, wherein a rear portion of the retaining spine is securely sandwiched by retaining plates of the blade mounting system. Furthermore, the trimming blade provides notches and/or recesses for facilitating such operative association. Each histology radius trimming blade embodies a radiused or otherwise uniquely shaped heel for cutting and dissecting tissue.

An improved ergonomic hand-held instrument is provided with a housing having external surfaces defining contours which ergonomically engage surfaces of a user's thumb, index finger and middle finger when the user grasps the instrument, to provide a large surface area of contact between the user's hand and the instrument. The increased area of contact, compared to traditional designs, decreases the required level of applied unit area pressure, and also provides for greater control in manipulating the instrument by a wide range of users. The housing holds a removable cartridge having a working end or tip. The working end may be a pen, pencil, scalpel, knife, stylus, brush or similar tool. The top outer surface of the instrument includes an index finger compression surface for placement of the user's index finger. Base for storage of the instrument and at least one removable cartridge is also disclosed.

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 safety cutting device includes a slidable insert that moves longitudinally within a cavity of a housing. The slidable insert has a cutting blade attached and moves within the housing from a safe position in which the blade is covered to an exposed position for cutting. The safety device has a release button positioned near an anterior end of the housing. A biasing member automatically retracts the blade when the release button is activated.

A handle system includes a body extending between a first end and a second end. The handle system also includes a slot extending, at least partially, in the body, the slot forming a cavity. The handle system further includes a carrier arranged, at least partially, within the slot, the carrier further comprising a friction locker and at least one arm coupled to the friction locker, the at least one arm being rotatable about the friction locker. The handle system also includes a cap arranged on at least one of the first end or the second end. The handle system further includes a blade coupled to the at least one arm, the blade being rotatable about the axis between a retracted position where the blade is positioned within the slot and an extended position where the blade extends outwardly from the body.
