Description

Three-dimensional double-layer CT guided puncture positioning frame

technical field

The invention relates to a three-dimensional double-layer CT guided puncture positioning frame, which belongs to the field of medical needle support brackets.

Background technique

At present, when performing CT positioning, a single-layer positioning device is usually used, and the positioning is not accurate enough. When medical personnel perform percutaneous puncture, normal tissues around the lesion may be damaged.

Patent No. CN201220305313.4 discloses a three-dimensional double-layer CT guided puncture positioning frame, which has many defects in the application process:

1. It can only be used for single-layer puncture positioning;

2. When positioning, it is necessary to mark the puncture point with a pen, and the positioning is not accurate enough;

3. The upper positioning guide wire is fixed with adhesive tape, which is not fixed firmly and is not easy to replace.

Contents of the invention

Based on the above deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a three-dimensional double-layer CT-guided puncture positioning frame that can realize multi-layer puncture positioning, accurate positioning, and simple and fast operation.

The three-dimensional double-layer CT guiding puncture positioning frame of the present invention includes a frame body, _a lower layer positioning guide wire and an upper layer positioning guide wire made of N1 groups of metals. The bases are connected by the positioning guide wires of the lower layers, and the positioning guide wires of the lower layers are arranged at equal intervals, and N ₂ sets of equally spaced slots are arranged side by side on the upper end faces of the left and right brackets, N ₂ ≥ N ₁ , each lower layer The positioning guide wire has a set of slots corresponding to it. The two ends of the upper positioning guide wire are bent downward to form a bent end, and the two bent ends are respectively inserted into the corresponding slots on the left and right frames. A set of sliders is set on the guide wire, and each set of sliders is formed by n slider bodies of different colors arranged in the same order.

In this guiding puncture positioning frame, each group of sliders includes a plurality of slider bodies of different colors arranged in a fixed order. For example, each group of sliders includes blue, yellow, purple, and white colors from left to right. , red 5 slider body. The slider body of each color is used for the puncture positioning of the first layer. For example, the red slider corresponds to the positioning of the first layer of puncture, and the purple slider corresponds to the positioning of the second layer of puncture. Through 5 slider bodies of different colors, 5 layers of puncture can be achieved, and the value of n is determined by the actual puncture needs.

The use process of the above-mentioned three-dimensional double-layer CT-guided puncture positioning frame is as follows:

When in use, place the three-dimensional double-layer CT-guided puncture positioning frame on the patient's body, fix it with adhesive tape, make the lower positioning guide wire contact with the human skin, and then slide all the slider bodies to the same side (left frame pedestal side or the right pedestal side), and then start to select the puncture point, for example, when performing double-layer puncture, place the red slider on the fifth upper positioning guidewire and the red slider on the tenth lower positioning guidewire Slide to the desired position respectively, the line between the two red sliders is the direction of the first layer of puncture, then move the purple slider on the second upper positioning guide wire and the sixth lower positioning guide wire Slide the purple sliders to the required positions, and the line between the two purple sliders is the direction of the second layer of puncture. By analogy, the need for n-layer puncture can be easily realized by using n kinds of color sliders. When the number of slots on the upper end surface of the frame base of the frame body is greater than the number of positioning guide wires in the lower layer, both vertical puncture and angle puncture can be realized, and the application range is wide.

The above-mentioned frame can be an integral structure, and can also be formed by connecting the upper fixing frame and the lower connecting plate up and down, and the upper fixing frames of the left and right frames are fixedly connected through the middle beam. There are many ways to connect the upper fixing frame and the lower connecting plate, and the present invention adopts the following preferred scheme: the upper fixing frame and the lower connecting plate are connected by a child and a female gluing button, and the child gluing buttons are fixed on the bottom of each leg of the upper fixing frame , the female Velcro is fixed on the upper surface of the lower connecting plate, the positions of the child and the female Velcro correspond to each other, and the fast connection between the upper fixing frame and the lower connecting plate is realized through the child and female Velcro, which is easy to operate and can be removed after use. The upper fixing frame and the lower connecting plate are disassembled, which is easy to carry.

In order to better fit the three-dimensional double-layer CT-guided puncture positioning frame to the human epidermis, the lower connecting plate is preferably made of flexible materials, such as rubber strips, and the lower positioning guide wire is preferably elastic guide wire.

In addition to the above, the two ends and the outer sides of the left frame and the right frame are provided with fixing strips. The adhesive tape can be easily pasted through the fixing strip, and it is more convenient to place the three-dimensional double-layer CT guided puncture positioning frame on the patient's body and fix it through the fixing strip and the adhesive tape. Preferably, the number of upper positioning guide wires is the same as that of the lower positioning guide wires.

The beneficial effect that the present invention has compared with prior art is:

The three-dimensional double-layer CT-guided puncture positioning frame has an ingenious structural design, and can realize multi-layer puncture positioning through a plurality of sliders of different colors arranged in a fixed order on the lower positioning guide wire and the upper positioning guide wire; It is necessary to move the slider of the corresponding color, and the positioning is simple and precise; each upper positioning guide wire is inserted into the slot, which is very convenient to take out and easy to replace, and an appropriate number of upper positioning guide wires can be installed according to the needs, making the use more flexible.
