ABSTRACT:
A needle holder which is used in laparoscopic surgeries by being inserted into a trocal tube inserted into a body cavity of a patient includes an elongated insertion rod having a tip portion; a holding member provided at the tip portion of the insertion rod for removably holding the needle; position control mechanism operable from the outside of the body for adjusting the position of the needle to be held by the holding member; fixing members for fixing the holding member with respect to the insertion rod at a state that the holding member has been adjusted by the position control mechanism; and switching mechanism for switching the state of the holding member between a first state in which the holding member is adjustable with the position control mechanism and a second state in which the holding member is fixed with respect to the insertion rod by means of the fixing members. The holding member is formed from a pair of pinch members each having a semi-spherical shape. The pinch members are joined together to form a substantially spherical body which is rotatable between the fixing member at the tip portion of the insertion rod, thereby enabling to adjust the position of the needle held between the pinch members easily from the outside of the body by operating the position control mechanism when carrying out the step of piercing body tissue during suturing inside the body cavity.
