According to one aspect, a hand assist device may be configured for use with an endoscope. The hand assist device may comprise a body configured to removably couple to a handle of the endoscope. The body may comprise a recess configured to receive the handle of the endoscope. The recess may extend from a proximal end of the body to a distal end of the body. The body may also comprise a palm support portion and a finger support portion proximal to the palm support portion. The body may further comprise a base support portion distal to the palm support portion.

An orthopaedic driving instrument including a first end portion, a second end portion opposite the first end portion, and a central portion, intermediate the first and second end portions, comprising a central section having an outer diameter representing a maximum outer diameter of the driving instrument. The first end comprises a first driving interface sized and shaped to, in operation of the instrument, engage a screw interface of a screw for applying torque to the screw. The second end comprises a second driving interface sized and shaped as the size and shape of the first driving interface.

A wrench structure includes a main body provided with a drive portion, a shank, a protruding block, a handle, a first connecting portion, and a second connecting portion. The shank has two first faces and two second faces formed on two sides thereof. The protruding block has two third faces and two fourth faces. The handle has two fifth faces and two sixth faces. The first connecting portion has two seventh faces and two eighth faces. Thus, the main body is sequentially provided with the drive portion, the shank, the second connecting portion, the protruding block, the first connecting portion, and the handle. The shank, the protruding block, the first connecting portion, and the handle have different height and width defined therebetween.

An oral hygiene device, in particular a toothbrush, includes at least one application unit having a base body, further includes at least one handle unit, in particular a manual handle unit, having a base body, and including at least one coupling unit for releasably coupling the application unit to the handle unit, wherein the base body of the handle unit has a hardness and/or a density that is greater than a hardness and/or density of the base body of the application unit.

A multi-component housing having a length and comprising at least a first component comprising a first plastic material, a second component comprising a second plastic material, and a third component comprising a third plastic material. The housing includes at least one tolerance-elimination element made of the second plastic material and longitudinally attached to the first component along the housing's longitudinal axis. The tolerance-elimination element has an average length extending parallel to the housing's longitudinal axis, which average length is at least ten times less than the length of the housing. The third component at least partially forms an outer surface of the housing, so that the tolerance-elimination element is at least partially overmolded by the third plastic material.

A handle of a hand tool includes a main body with a front annular portion, a gripping portion, and a tail portion. The gripping portion has a first expanded section and a reduced section. The outer diameter of the first expanded section, whose front end is connected to the front annular portion, is increased rearward. The outer diameter of the reduced section, which is connected to the rear end of the first expanded section, is reduced rearward. The tail portion has a second expanded section and a closure section. The outer diameter of the second expanded section, whose front end is connected to the rear end of the reduced section, is increased rearward. The outer diameter of the closure section, whose front end is connected to the second expanded section, is reduced rearward. The junction between the reduced section and the second expanded section forms an annular recess.

A combination snake catching and killing device is provided. The device includes an elongated hollow body configured to house a blade assembly with a blade used for dismembering a snake when fired. A handle assembly includes a handle, a charge handle configured to cock and fire the blade, and a grip lever configured to activate a gripping member with jaws that can grip a snake allowing a user to handle and/or relocate a snake or kill the snake, as necessary.
