Description

Technical Field

[0001] The present invention relates to a guide frame, and in particular to a multi-dimensional puncture guide frame for interventional ultrasound. Background Art

[0002] Interventional ultrasound technology, as a branch of modern ultrasound medicine, is a new technology developed on the basis of ultrasound imaging to further meet the needs of clinical diagnosis and treatment. The application of ultrasound probes configured with puncture stands for puncture surgery is very extensive. The puncture needles used in different surgeries are of different models, and the puncture needles must be easily separated from the puncture stand. During the puncture process, the puncture stand must be able to clamp the puncture needle well and achieve stable needle insertion guidance. Ultrasonic puncture guides are used in the field of inductive puncture of patients in medicine, avoiding errors caused by manual puncture, and are therefore widely used.

[0003] There are still some defects and deficiencies in the current use of the guide frame. The specific areas that need improvement are as follows: Existing guide frames are not easy to adapt and adjust according to the in-plane method and the out-of-plane method; When using the in-plane method and the out-of-plane method, the existing guide frame is not easy to quickly disassemble the adjustment component after the puncture is completed, thereby affecting the subsequent puncture operations; Existing guide frames are mostly set near the ultrasound probe, and their angle adjustment mostly relies on hand-gripping. This makes the support for multi-dimensional angle adjustment unstable, thus affecting the puncture effect. The existing guide frame does not have the function of locating the patient's puncture site, so the operator's hand needs to be suspended in the air for support, which increases the operator's arm fatigue; The existing guide frame has a relatively simple function and is not convenient for adjusting the patient's upper limbs or lower limbs.

Then, the moving mechanism 3 is rotated so that the adjustment mechanism 2 and the guide mechanism 1 on the moving mechanism 3 are rotated to be located above the two support plates 5 and correspond to the positioning slots. Then, the lifting plate 323 is released so that the fourth elastic member 322 pushes the two limiting plates 321 into the positioning slots. In this way, the moving mechanism 3 after rotation adjustment can be fixed, thereby facilitating puncture guide adjustment of the upper or lower limbs.

[0033] The operating steps of the present invention are: The in-plane method can be operated by rotating the worm 15 on the guide mechanism 1. The worm 15 drives the worm wheel 17 and the first rotating shaft 16 to rotate synchronously. The first rotating shaft 16 drives the gear 18 to rotate and engage to drive the tooth plate 12 to move closer to the clamping assembly 14, thereby adjusting the tooth plate 12 to drive the adjustment assembly 13 to approach the clamping assembly 14, and then place the ultrasonic probe between the clamping plate 145 and the clamping pad 147 on the clamping assembly 14, and then rotate the first screw 146 to drive the clamping plate 145 to clamp and fix the ultrasonic probe, and then pull the adjustment assembly The telescopic rod 135 on the 13 drives the brake column 137 to disengage from the brake hole 138, and then rotates the second stabilizing plate 133 to drive the guide tube 134 to tilt to a suitable angle. At the same time, the telescopic rod 135 drives the first fixing ring to squeeze the first elastic member 136. After the guide tube 134 is rotated to a suitable angle, the telescopic rod 135 can be released to push the brake column 137 into the corresponding brake hole 138, thereby angularly positioning and fixing the second stabilizing plate 133 and the guide tube 134. This makes it easier to perform guided puncture using the in-plane method. The out-of-plane method is to detect the depth of the puncture point, and then rotate the worm 15, which drives the worm gear 17 and the first rotating shaft 16 to rotate synchronously. The first rotating shaft 16 drives the gear 18 to rotate and engage to drive the toothed plate 12 to move away from the clamping assembly 14, thereby adjusting the distance between the guide tube 134 on the adjusting assembly 13 and the ultrasonic probe clamped on the clamping assembly 14 to be consistent with the depth of the puncture point, and then pull the telescopic rod 135 on the adjusting assembly 13 to drive the brake column 137 to disengage from the brake hole 138, and then rotate the second stabilizing plate 133 to drive the guide tube 134 to tilt to 45°. At the same time, the telescopic rod 135 drives the first fixing ring to squeeze the first elastic member 136, so that the guide tube 134 can be rotated to a suitable angle, and then the telescopic rod 135 can be released to push the brake column 137 into the corresponding brake hole 138, so that the second stabilizing plate 133 and the guide tube 134 are adjusted 45° and then positioned and fixed. In this way, the out-of-plane method can be used to guide puncture. To disassemble the adjustment assembly 13, the second fixing ring on the first push-pull column 1310 is pulled to squeeze the second elastic member 1311, thereby driving the inner insert plate 1312 to separate from the hole plate 122. In this way, the adjustment assembly 13 can be lifted up and disconnected from the tooth plate 12, thereby facilitating the withdrawal of the guide frame and subsequent puncture operations. For the dimensional adjustment of the guide mechanism 1, the brake assembly 22 on the adjusting mechanism 2 is adjusted, and the blocking plate 225 on the brake assembly 22 is pulled to move and disengage the tooth groove on the semicircular tooth groove plate 210, and then the brake assembly 22 is rotated to rotate, so that the brake assembly 22 drives the fourth rotating shaft 21 on the adjusting mechanism 2 to rotate, so that the fourth rotating shaft 21 can drive the guide mechanism 1 to rotate as a whole to adjust the flip angle. After adjusting to a suitable angle, the second push-pull column 222 can be pulled so that the limiting ring 223 on the second push-pull column 222 squeezes or stretches the two third elastic members 224, so that the second push-pull column 222 drives the blocking plate 225 to correspond to the tooth groove on the semicircular tooth groove plate 210, and then pushes the blocking plate 225 to be stuck on the tooth groove to form a brake, so that the rotation angle can be positioned and fixed; Then, the spiral ring 23 is rotated along the spiral pattern on the fourth rotating shaft 21, so that the spiral ring 23 moves, driving the inner ring 232 on the outer ring 231 to move synchronously and pushing the limit ring 241 and the push-pull ring 24 to move synchronously. In this way, the two first clamping shafts 242 on the push-pull ring 24 can drive the two linkage plates 25 to move, so that the two linkage plates 25 drive the second clamping shafts 26 and the two third flip plates 27 to rotate and tilt along the fifth rotating shaft 28. In this way, the third flip plates 27 can drive the guide mechanism 1 as a whole to rotate and tilt, thereby adjusting the support in different dimensions. For the adjustment of the moving mechanism 3, by rotating the second screw rod 33, the second screw rod 33 drives the lifting plate 34 to synchronously adjust the lifting height, so as to adjust it to the appropriate height, and then rotate the third screw rod 36, so that the third screw rod 36 drives the push plate 35 to move synchronously, and the push plate 35 synchronously drives the adjustment mechanism 2 and the guide mechanism 1 to move, so as to facilitate the support and fixation of the patient's puncture point. For the rotation adjustment of the moving mechanism 3, by pulling the lifting plate 323 on the limiting assembly 32 upward, the lifting plate 323 drives the two limiting plates 321 to disengage from the positioning grooves on the two supporting plates 5. At the same time, the two limiting plates 321 squeeze the two fourth elastic members 322, and then rotate the moving mechanism 3 so that the adjustment mechanism 2 and the guide mechanism 1 on the moving mechanism 3 rotate to be located above the two supporting plates 5 and correspond to the positioning grooves, and then release the lifting plate 323, so that the fourth elastic member 322 pushes the two limiting plates 321 into the positioning grooves, so that the moving mechanism 3 after rotation adjustment can be fixed, so as to facilitate the puncture guide adjustment of the upper or lower limbs.
