An adjustable stroke length percussion massage device includes a stroke arm connected to a piston which is connected to a massage tool for providing a massage to a user. The stroke arm is secured to a crank pin of a crank mechanism which includes a rotatably connected crank housing and crank base, the crank pin being movably secured between the crank housing and crank base such that the crank pin moves from a first end to a second end of a sliding groove located in the cam housing when a rotation direction of the single unit is reversed by a motor. When the crank pin is moved from the first end to the second end of the sliding groove, a stroke length of the piston is changed.

A percussive massage adaptor and device for delivering effective masseusive contact with a body while providing tactile feedback to the masseuse includes a flexible hand sleeve having a pressure distribution element on a top surface above the masseuse's backhand. A reciprocating shaft, powered by a motor, contacts the pressure distribution element to distribute percussive forces to the hand and fingers of the masseuse.

A system and method of using a lead introduced to a subject proximate to a region of pain is contemplated to deliver pain relief without the need for multiple needle insertions or electrical stimulation. The three-dimensional lead may include spring-like characteristics and/or coils to translate mechanical energy into the therapy.

A percussive massage device may include a housing having a housing interior. A motor may be positioned in the housing interior and may include a rotatable motor shaft having a motor axis. A battery may be positioned in the housing interior. A switch may be configured to activate the motor. A reciprocating shaft may operatively be connected to the rotatable motor shaft. The reciprocating shaft may include a distal end and is able to reciprocate in response to rotation of the rotatable motor shaft. A vent may extend through a vent opening in the housing to provide ventilation to the housing interior.

A percussion massager feature describe herein provides for locking the control display through the touchscreen of the percussion massager to ensure accidental bumps to the display do not disrupt treatment.

Disclosed is a handheld tool using a battery pack (1). A positioning hole (118) is provided on the surface of the battery pack, a locking mechanism (31) matching the positioning hole is provided inside the handheld tool for locking or unlocking the battery pack, and an ejection mechanism (32) is further provided inside the handheld tool to work in conjunction with the locking mechanism to eject the battery pack when the battery pack is unlocked. The battery pack of the handheld tool can be completely inserted into a holding portion of the handheld tool, such that the tool can be made smaller. Moreover, the battery pack has a smooth surface and is convenient to carry, such that assembly/disassembly of the battery pack into/from the tool is more convenient. In addition, there is no detached gap between a tool housing and the battery pack on the surface of the tool, such that the appearance of the tool is more aesthetic.
