A syringe adaptor comprises: a body having a penetration hole formed therein, and having a first hole formed in the lower surface of the penetration hole to enable a syringe needle of a syringe to be inserted therein; an operator inserted in and coupled with the penetration hole to open the first hole; one or more piezoelectric bodies formed between the inner surface of the body and the penetration hole, and moving the operator in a length direction or an opposite direction of the syringe according to predetermined signal; a mounting unit having a second hole formed in a front end position opposed to the first hole, having the front end position coupled with a part of the lower surface of the body, having an elastic member disposed therein to be shrunken by the syringe, and having a syringe insertion hole formed in the rear end thereof to enable a syringe to be coupled therewith; an attachment plate coupled with the front end of the operator, moved by the movement of the operator, attached to an object, and having a third hole for enabling the syringe needle to be inserted therein and moved therewith; and an operating device for operating the piezoelectric bodies by applying the signal to the piezoelectric bodies according to a control command or a control parameter received from the outside. An insertion depth of a syringe needle with respect to a patient can be automatically adjusted. |
