A surgical clipper blade assembly includes a stationary blade and a moveable blade adjacent the stationary blade. The moveable blade is configured to reciprocate relative to the stationary blade to remove hair from a skin area. A blade housing houses the stationary blade and the moveable blade. The blade housing has a guide surface that faces the skin area during a hair removal process. A skin conditioning member in the form of a pad that extends along at least one of a skin facing surface of the stationary blade and the guide surface of the blade housing. The skin conditioning member includes a skin preparation composition. Reciprocating motion of the moveable blade vibrates the skin conditioning member against the skin area as the skin preparation composition is released onto the skin area.

A surgical hair clipper assembly includes a clipper body and a blade assembly connected to the clipper body. The blade assembly includes a moveable blade configured to reciprocate to remove hair from a skin area and a blade housing that houses the moveable blade. The blade housing has a guide surface that faces the skin area during a hair removal process. A suction attachment includes a clipper attachment connected to the clipper body and a nozzle structure connected to the clipper attachment and extending distally to an end. The end is located no more than about ten millimeters proximal of a plane defined by the guide surface.

Suction attachments for surgical hair clippers and methods of using such suction attachments

A surgical hair clipper includes a clipper body and a blade assembly connected to the clipper body. The blade assembly includes a moveable blade configured to reciprocate to remove hair from a skin area and a blade housing that houses the moveable blade. The blade housing has a guide surface that faces the skin area during a hair removal process. A touch sensor is exposed at the guide surface for contact with the skin area during use. A processor receives a signal from the touch sensor when the touch sensor contacts the skin area. The processor uses logic saved in a memory to instruct a feedback device to provide an indication of skin contact between the touch sensor and the skin area.

An adjustable length laparoscopic instrument is provided. The instrument includes a shaft with a shaft distal end and a shaft proximal end. The instrument further includes an actuation rod with an actuation rode distal end and an actuation rod proximal end. The actuation rod is receivable by the shaft such that the actuation rod can translate longitudinally relative to the shaft to actuate an end effector. The instrument further includes a handle configured to hold the shaft and the actuation rod. The handle is configured to cause the actuation rod to translate longitudinally relative to the shaft to actuate the end effector. The instrument further includes a length adjustment mechanism configured to adjust a shaft length. The shaft length is defined between the handle and the shaft distal end.

Adjustable length laparoscopic instrument

An adjustable retractor blade and retractor system are disclosed. The retractor blade includes a fixed portion, extendible portion, and means for adjusting the length of the retractor blade. The means for adjusting may include a threaded rod engaging the fixed portion with the extendible portion. In one aspect, the extendible portion includes a plurality of stackable members, with the length of the adjustable blade adjusted by attaching stackable members. In one aspect, the fixed portion includes a plurality of holes, and the extendible portion includes at least one post, the plurality of holes configured to receive the at least one post, with the length of the adjustable blade adjusted by slidably displacing the extendible portion until the at least one post engages with at least one of the plurality of holes. Methods are provided for adjusting the length of a retractor blade.

Adjustable length, reusable retraction blades

A trocar assembly includes a cannula having a proximal portion and an opposing distal portion. The distal portion is configured to extend into a patient body. The cannula defines an access channel between the proximal portion and the distal portion, wherein the access channel is configured to receive a scope such that the scope can be maneuvered through the access channel to a location within the patient body. A cleaning element at the distal portion is configured to contact at least a distal end of the scope.

Trocar assembly with a cleaning element for use during a laparoscopic procedure

A trocar assembly with an integrated scope-cleaning structure may have a proximal portion configured for accessibility by a user and a cannula extending distally from the proximal portion and configured to extend distally into a patient body, where the cannula is further configured to receive a distal end of a scope such that the scope can be maneuvered through the cannula to a location within the patient body. A cleaning element may be included, where the proximal portion includes a housing, where the cleaning element is substantially located within the housing.

Trocar assembly with a movable cleaning element

The present disclosure relates to a trocar assembly with an integrated scope-cleaning structure. The trocar assembly may include a housing defining boundaries of a chamber with (a) a proximal opening configured to receive a distal end of a scope, and (b) a distal opening in fluid and mechanical communication with a trocar cannula. The trocar assembly may further include a cleaning element located at least partially between the proximal opening and the distal opening, where the cleaning element is movable with respect to the housing from at least a first setting where a first portion of the cleaning element may be in a first location and may form a first cleaning surface within the chamber, the first cleaning surface configured to remove debris from a distal end of the scope when the distal end of the scope contacts the first portion of the cleaning element.

The present disclosure relates to a housing for a laparoscopic trocar assembly with an integrated scope-cleaning structure. The housing may include a shell forming a wall portion of a chamber and a cleaning element forming at least a portion of an internal surface of the chamber, the cleaning element configured to remove debris from a distal end of a scope upon contact between the cleaning element and the distal end of the scope. The cleaning element may be movable with respect to the shell of the housing in response to an input force upon the shell that moves a portion of the shell and a portion of the cleaning element between a default state and a displaced state.

The present disclosure relates to a trocar assembly with an integrated scope-cleaning structure. The trocar assembly may include a chamber with a proximal opening configured to receive a distal end of a scope. A cannula extend distally from the chamber and may be configured to extend distally into a patient body. The cannula may be further configured to receive the distal end of the scope such that the scope can be maneuvered through the cannula to a location within the patient body. The trocar assembly may include a cleaning element forming a surface within the chamber, where the surface of the cleaning element is configured to remove debris from at least one non-longitudinal, end-facing surface of the scope.
