Description

Technical Field

[0001] The utility model relates to the technical field of puncture positioning, in particular to a puncture accurate positioning guide. Background Art

[0002] The puncture precision positioning guide is a device used to help doctors accurately position the puncture during medical procedures. It usually consists of a guide needle or catheter, which can help doctors accurately guide the puncture instrument to the target location in the patient's body through X-rays, ultrasound or other imaging technologies. This guide can improve the accuracy and safety of the operation, reduce the operation time and risk of injury, and is suitable for a variety of interventional surgeries and treatments.

[0003] Currently, when performing puncture on patients, doctors often hold the ultrasound probe with one hand to determine the puncture position through the instrument, and use the other hand to hold the puncture needle for puncture. The puncture needle often needs to be tilted to penetrate the skin. However, holding the puncture needle with one hand requires both ensuring the puncture angle and gradually exerting force to penetrate the puncture needle, which is easily affected by hand shaking and produces deviations, thereby affecting the puncture accuracy.

[0004] In view of the above problems, the utility model document proposes a puncture precise positioning guide. Utility Model Content

[0005] The utility model provides a precise puncture positioning guide, which solves the shortcomings of the prior art that when holding the puncture needle with one hand, it is necessary to ensure the puncture angle and gradually exert force to pierce the puncture needle, which is easily affected by the shaking of the hand and causes deviation, thereby affecting the puncture accuracy.

[0006] The utility model provides the following technical solutions:

[0007] A puncture precise positioning guide, comprising:

[0008] A support box, the support box is placed vertically, and a needle sleeve for the puncture needle to pass through is provided outside the box opening of the support box;

[0009] An adjustment component is arranged on the support box and is used to adjust the position of the needle sleeve at multiple angles. The adjustment component includes a threaded rod rotatably installed on both ends of the inner wall of the support box, a sliding seat is threadedly connected to the threaded rod, one side of the sliding seat passes through the box opening of the support box and is fixedly installed with an electric push rod, a U-shaped frame is fixedly provided at the output end of the electric push rod, a rotating seat is rotatably installed on the outer wall of the U-shaped frame, and the outer wall of the needle sleeve is fixedly connected to the inner wall of the rotating seat.

[0010] In a possible design, a first driving motor for driving the threaded rod to rotate is fixedly mounted on the top of the outer wall of the support box.

[0011] In a possible design, a second driving motor for driving the rotating seat to rotate is fixedly installed in the U-shaped frame.

[0012] In a possible design, limiting sliding blocks are fixedly provided on both sides of the sliding seat, and limiting sliding grooves for slidably installing the limiting sliding blocks are provided on the inner wall of the support box.

[0013] In a possible design, an arc-shaped clamping piece is provided inside the needle sleeve, a threaded tube is connected to the outside of the needle sleeve, a hand-tightening bolt is threadedly connected to the threaded tube, one end of the hand-tightening bolt passes through the inner wall of the needle sleeve and is rotatably connected to the outer wall of the arc-shaped clamping piece.

[0014] In a possible design, an L-shaped connecting frame is fixedly provided on the outer wall of the support box, and a fastening sleeve for fixing the device on the ultrasonic probe is fixedly provided on the other end of the L-shaped connecting frame.

[0015] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0016] In the present application, when in use, the fastening sleeve is put on the ultrasonic probe and the bolts on the fastening sleeve are tightened, so that the device is fixed on the ultrasonic probe to reduce accidental shaking. The ultrasonic probe is placed close to the epidermis of the part to be punctured, and then the part to be punctured detected by the ultrasonic probe is observed through the external display. Then, the threaded rod is driven to rotate by the first driving motor, and under the limiting action of the limiting slider and the limiting slide groove, the sliding seat is prompted to slide up and down to change the longitudinal position of the needle sleeve, and the lateral position of the needle sleeve is changed by the extension and contraction of the output end of the electric push rod. The rotating seat is driven to rotate by the second driving motor to change the inclination angle of the needle sleeve, thereby accurately adjusting the position of the needle sleeve, and helping to reduce hand shaking to improve the puncture accuracy;

[0017] After adjusting the position of the needle sheath according to the depth of the puncture site, the puncture needle can be passed through the needle sheath for puncture. The hand-tightened bolt can be screwed according to the radius of the puncture needle to make the arc-shaped clamping piece fit the outer wall of the puncture needle to adapt to the use of puncture needles with different radii. It can also reduce the shaking of the puncture needle, which helps to further improve the puncture accuracy.

[0018] The utility model has the following beneficial effects:

[0019] The utility model can fix the device on the ultrasonic probe by arranging the fastening sleeve, thereby reducing accidental shaking. By arranging the adjustment component, the position of the needle sleeve can be accurately adjusted, and it helps to reduce hand shaking to improve puncture accuracy.

[0020] In the utility model, the hand-tightening bolt is screwed to make the arc-shaped clamping piece fit the outer wall of the puncture needle, so as to adapt to the use of puncture needles with different radii, and the shaking of the puncture needle can be reduced, which helps to further improve the puncture accuracy.
