APPLICATOR FOR POWER INFLUENCE BY MICROKNIVES SET Russian patent published in 2006 - IPC A61B17/20 

FIELD: surgery.

SUBSTANCE: applicator can be used for through-skin injection of matters. Devices for power influence by penetrating member onto corneous layer have case with first and second ends, piston, power spring, blocking mechanism and unblocking mechanism. First end of case is made for placement of penetrating member. Piston is disposed for slide inside the case for power influence by penetrating member on corneous layer. Power spring intends for generation of influence force onto piston and for displacement of piston behind first end of case. The spring is capable of compressing matter along the passage of piston inside case. Blocking mechanism is made for unblock of engagement of piston and case by one hand after the piston finds its place inside the case. Power spring effects by piston onto penetrating member and presses penetrating member out into mentioned corneous layer. Methods of triggering of the device and of power influencing by penetrating member onto corneous layer have steps of displacement and block of device with piston and case. Displacement of piston to position of triggering relatively case is carried out by pressing piston and case with blocked piston at triggering position by mentioned pressing. Device is made for triggering and blocking by means of one hand only. As a result spring-loaded applicator is proposed for through-skin member which is triggered by one hand of user.

EFFECT: improved efficiency; minimal force of hand.
