The guide device for needle puncture according to one embodiment of the present invention comprises: a body; a guide part which has a guide hole provided therein so as to be tilted at a certain angle along the height direction, the guide hole allowing an injection needle to pass therethrough so that during injection needle puncture, the insertion angle of the injection needle can be constantly maintained; and a sliding member which is coupled to the body so as to be slidingly movable, wherein the spaced distance between the guide hole and a medical ultrasound apparatus is adjusted through relative movement of the body or the sliding member so that a target location into which the distal end of the injection needle is inserted can be located on entrance path of the injection needle. ## Claims ### Claim 1 A guide device for injection needle puncture, the guide device comprising: a body; a guide part that has a guide hole provided therein to be tilted at a certain angle along a height direction, the guide hole allowing an injection needle to pass therethrough so that, when the injection needle is punctured into a human body, an insertion angle of the insertion needle is guided and the insertion angle is constantly maintained; and a sliding member slidably coupled to the body, wherein a separation distance between a medical ultrasound apparatus and the guide hole is adjusted so that a target position into which an end of the injection needle is to be inserted is located on an entry path of the injection needle by relative movement of the body or the sliding member, wherein the guide part includes a guide main body rotating about a hinge shaft with respect to the body to adjust an angle of the guide hole, and the guide hole is formed to penetrate the guide main body along a height direction of the guide main body, wherein a plurality of angle adjustment grooves that are concentrically arranged about the hinge shaft are provided at one side of the guide main body, and a fixing pin that is inserted through a side portion of the body is inserted into the angle adjustment grooves to fix the angle of rotation of the guide main body. ### Claim 2 (depends on 1) The guide device of claim 1, wherein a partial length of the guide hole including an upper end exposed to the outside is formed to have a cross-sectional area that is relatively larger than a remaining portion so that insertion of the injection needle into the guide hole is facilitated. ### Claim 3 (depends on 1) The guide device of claim 1, wherein a cross-sectional area of the guide hole gradually decreases from top to bottom at least partially or entirely so that insertion of the injection needle into the guide hole is facilitated. ### Claim 4 (depends on 1) The guide device of claim 1, further comprising a scales part to check the separation distance between the medical ultrasound apparatus and the guide hole. ### Claim 5 (depends on 4) The guide device of claim 4, wherein the scales part has the form of a ruler provided along a longitudinal direction at one surface of the sliding member. ### Claim 6 (depends on 4) The guide device of claim 4, wherein the scales part has the form of a ruler provided along a longitudinal direction at one surface of the body. ### Claim 7 (depends on 4) The guide device of claim 4, wherein an indicator configured to indicate a position corresponding to a lower end of the guide hole is provided at one side of the body. ### Claim 8 (depends on 1) The guide device of claim 1, wherein the guide hole is formed to penetrate the body along the height direction of the body. ### Claim 9 (depends on 1) The guide device of claim 1, wherein a lever part is provided at one end of the hinge shaft. ### Claim 10 (depends on 1) The guide device of claim 1, wherein an angle indicating part is provided at one side of the body to check an angle of rotation of the guide main body. ### Claim 11 (depends on 1) The guide device of claim 1, wherein the separation distance between the guide hole and the medical ultrasound apparatus is a linear distance between the lower end of the guide hole and a lower end of the medical ultrasound apparatus. ### Claim 12 (depends on 1) The guide device of claim 1, wherein an angle of inclination of the guide hole is formed to be an angle in the range of 0° to 90° with respect to a horizontal surface. ### Claim 13 (depends on 12) The guide device of claim 12, wherein the angle of inclination of the guide hole is formed to be any one angle of 30°, 45°, or 60° with respect to the horizontal surface. ### Claim 14 (depends on 1) The guide device of claim 1, wherein a contact part coming into contact with one surface of the medical ultrasound apparatus is provided at a free end side of the sliding member. ### Claim 15 (depends on 14) The guide device of claim 14, wherein the contact part is a plate-shaped member perpendicularly extending from an end of the sliding member toward one side. ### Claim 16 (depends on 1) The guide device of claim 1, wherein a stopper member configured to restrict movement of the sliding member is provided in the body. ### Claim 17 (depends on 16) The guide device of claim 16, wherein the stopper member is at least one set screw that is screw-coupled to one side of the body, and when the set screw moves by rotation, an end of the set screw presses the sliding member at the middle of the length thereof.
