Disclosed herein is an instrument that enables the in situ formation of architected planar biomaterials and tissues by translating a printer head along a deposition surface such as a patient having burn injuries. In handheld embodiments of the instrument, cell-laden biopolymer solutions are perfused through a moving microfabricated printer head and deposited onto a stationary planar surface or a wound. The printer head may be translated via a drive mechanism. A soft deformable roller mitigates further damage to the injured area of skin as it rolls over it and a gimbal mechanism to which the printer head is attached is in contact with the injured tissue but is configured so that the printer head while in contact with tissue, does not exert undue pressure on the would area.

Devices and methods for wound-conformal guidance of bioprinter printhead

Disclosed herein is a bioprinter that enables the in situ formation of architected planar biomaterials and tissues by translating a printer head along a deposition surface, such as skin wounds. In handheld configurations of of the instrument, cell-laden biopolymer solutions are perfused through a moving microfabricated printhead and deposited onto a stationary planar surface or a wound. The printer head may be translated via a drive mechanism. Different embodiments of the instrument are disclosed form vivo application in small animals, as well as for large animal and clinical application. A stationary embodiment of the instrument is well suited for the continuous formation and roll-to-roll processing of planar biomaterials and tissues.

The present invention is a training device that helps the players of cue sports to realize their mistakes and improve their skills. The device comprises of a laser module that can be placed onto the cue to emit a line laser on the cue ball, the target ball and the playing surface or ground as an aiming guide. The device comprises of a self-balancing system to automatically hold the laser on top of the cue for a proper beam. The device further comprises of a control board to program different duty cycles and coaching scenarios of the device.
