Embodiment 1

[0022] as attached Figure 1-3 As shown, the puncture positioning guide for percutaneous nephrolithotomy of the present invention has a structure of a puncture positioning guide for percutaneous nephrolithotomy, including a square, a 90° protractor 2, a half-groove pointer 3, It is characterized in that a level 5 is installed on the long arm 4 of the square, a groove a7 is opened on the short arm 6 of the square, and a hole is drilled at the center of the protractor 2 at 9 places, and a half-groove pointer 3 is installed there; Open a groove b8 at 10 cm from the bottom edge of the protractor 2, install a level 5 on the protractor 2, and connect the protractor 2 and the square through the connecting piece 1 through the groove a7 and the groove b8. The groove a7 on the short arm 6 of the square is 5cm long, and the width is 0.2cm. The groove b8 on the protractor 2 is 6 cm long and 0.2 cm wide. The protractor 2 can move left and right along the groove b8 of itself, and can also...

Embodiment 2

[0025] as attached Figure 1-3 As shown, the puncture positioning guide for percutaneous nephrolithotomy of the present invention has a structure of a puncture positioning guide for percutaneous nephrolithotomy, including a square, a 90° protractor 2, a half-groove pointer 3, It is characterized in that a level 5 is installed on the long arm 4 of the square, a groove a7 is opened on the short arm 6 of the square, and a hole is drilled at the center of the protractor 2 at 9 places, and a half-groove pointer 3 is installed there; Open a groove b8 at 15 cm from the bottom edge of the protractor 2, install a level 5 on the protractor 2, and connect the protractor 2 and the square by bolts passing through the groove a7 and the groove b8. The groove a7 on the short arm 6 of the square is 7.5cm long and 0.3cm wide. The groove b8 on the protractor 2 is 9 cm long and 0.3 cm wide. The protractor 2 can move left and right along the groove b8 of itself, and can also move up and down alo...

Abstract

The invention relates to medical appliances, in particular to a puncture positioning guide device for percutaneous nephrolithotomy, which consists of a try square, a protractor and a semi-groove-shaped pointer, and is characterized in that: a level gauge is installed on a long arm of the try square, and a groove a is arranged on a short arm. The circle center of the protractor is retained, a hole is drilled at the circle center, the semi-groove-shaped pointer is installed at the hole, and a puncture needle can be arranged in the semi-groove-shaped pointer; and a groove b is arranged at the bottom edge of the protractor, the level gauge is installed on the protractor, and a connecting piece is used for penetrating through the grooves a and b to connect the protractor and the try square together. The protractor can move left and right along the groove thereof, and also can move up and down along the groove on the short arm of the try square. The puncture positioning guide device is convenient and quick to use, can greatly improve the safety, accuracy and efficiency of surgery, can prevent or obviously reduce the X-rays and computed tomography (CT)-rays which are required by positioning, and has a better social effect.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a puncture positioning guide for percutaneous nephrolithotomy. Background technique [0002] At present, when performing percutaneous renal puncture, X-ray positioning puncture, B-ultrasound positioning puncture, and CT positioning puncture are often used. In X-ray positioning puncture, when the patient is prone, vertical and horizontal fluoroscopy is performed on the stone, and then the side of the stone is viewed. Direction, relying on the operator to constantly adjust the angle between it and the horizontal plane for puncture. The fluorescent screen is only a two-dimensional image displayed, and cannot display the puncture depth and puncture direction. It is necessary to adjust the puncture depth and puncture direction during puncture. Repeated puncture may easily lead to Bleeding increases the pain of the patient; B-ultrasound positioning puncture When the puncture ne...
