First Claim
1. A puncturing guide for guiding a puncturing needle into a target site within a patient'"'"'s body, comprising:
- a base plate adapted to be positioned on the patient'"'"'s body at a defined puncturing entrance point,a needle guide adapted to guide the puncturing needle during insertion, anda retainer for securing the needle guide in a fixed position relative to the base plate,wherein the base plate is connected to a first section pivotable about a first axis and a second section pivotable about a second axis and attached to the needle guide such that the first and second sections are in a slidable arrangement,wherein said first and second sections cooperate in such a way that the needle guide is movable around a point that coincides with the defined puncturing entrance point,wherein the first section and the second section have shapes of two semi-circular equally sized bows pivotally attached to the base plate at positions separated by 90°
,wherein a slit is provided in each bow,wherein the needle guide is adapted to be arranged in the slits at an intersection point of the bows such that the needle guide is movable around the point that coincides with the defined puncturing entrance point,wherein the retainer has internal threads that mate with corresponding external threads on an upper part of the needle guide such that the needle guide is rotated to tighten and loosen the retainer to secure the needle guide in the fixed position.

Abstract
The invention provides a puncturing guide (1, 16) for guiding a puncturing needle into a target site within the body of a patient. The puncturing guide (1, 16) comprises a base plate (2, 17), a needle guide (3, 18), a retainer (4, 19) for securing the needle guide (3, 18) to the base plate (2, 17), a first segment (7, 20) of a first semi-sphere, a second segment (8, 21) of a second semi-sphere, and a needle guide (3, 18) attached to the second segment (8, 21). During a positioning operation, the second segment (8, 21) slides on the first segment (7, 20), so that the needle guide (3, 18) is movable around the center of the first semi-sphere, which is in level with the underside of the base plate (2, 17), thereby providing the possibility to position the tip of a puncturing needle at a puncturing point on the patient'"'"'s skin and then, in a separate operation, set the entrance angle of the puncturing needle without changing its entrance point.

7. A puncturing guide for guiding a puncturing needle into a target site within a patient'"'"'s body, comprising:
-
a base plate adapted to be positioned on the patient'"'"'s body at a defined puncturing entrance point, a needle guide adapted to guide the puncturing needle during insertion, and a retainer for securing the needle guide in a fixed position relative to the base plate, wherein the base plate is connected to a first section and a second section attached to the needle guide such that the first and second sections are in a slidable arrangement relative to each other, wherein the first and second sections are configured to allow the needle guide to be set such that a tip of the puncturing needle is located at the defined puncturing entrance point, wherein the first and second sections are configured to permit adjustment of the needle guide, prior to insertion, such that an entrance angle of the puncturing needle can be adjusted while prohibiting movement of the needle guide that would cause the tip of the puncturing needle to move from the defined puncturing entrance point, and wherein the retainer has internal threads that mate with corresponding external threads on an upper part of the needle guide such that the needle guide is rotated to tighten and loosen the retainer to secure the needle guide in the fixed position. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
