Description

Technical Field

[0001] The utility model relates to the technical field of ultrasound-guided thermal perfusion puncture devices, in particular to an ultrasound-guided thermal perfusion puncture device. Background Art

[0002] Hot perfusion refers to the process of heating liquid medicine to a set temperature, then injecting it into the human chest and abdominal cavity, and then expelling it from the body after it acts in the chest and abdominal cavity for a set period of time.

[0003] Existing puncture methods include: 1. Anatomical landmark positioning method: This method relies on the doctor's in-depth understanding of the human anatomy; the puncture point is located by touching or visually observing surface landmarks, such as bone protrusions, muscle courses, etc. This method is simple and easy to use, but requires the doctor to have rich clinical experience and anatomical knowledge. 2. Radiological positioning method: Before treatment, radiological techniques such as X-rays, CT or MRI can be used to scan the body cavity to determine the exact location of the puncture point; this method can provide more accurate positioning information, but may require additional equipment and time. 3. Surface marking method: Based on radiological positioning, markings can be made on the body surface so that the puncture point can be found quickly and accurately during surgery; this method combines the accuracy of radiology with the convenience of surface positioning.

[0004] During hot perfusion therapy, ensuring accurate puncture positioning is essential to avoid injury. Therefore, whether the position of the puncture needle can be observed more intuitively during the puncture process will greatly affect the positioning accuracy, efficiency, and patient comfort.

The first arm 200 of the first bracket 20 is rotatably connected to the third arm 210 of the second bracket 21. The second arm 201 of the first bracket 20 is provided with a first connecting portion 202, and the fourth arm 211 of the second bracket 21 is provided with a second connecting portion 212. The first connecting portion 202 and the second connecting portion 212 are connected by a connecting screw 5.

[0028] The first bracket 20 is provided with a fixed support 204, and the fixed support 204 is provided with a mounting groove 206. The puncture needle 3 is fixedly installed in the mounting groove 206 by the fastener 4, and the puncture needle 3 faces the working direction of the probe 10;

[0029] The fixed support 204 is generally located on the upper side or the lower side of the probe 10, and can be set in the center. The purpose is to reduce the insertion angle of the puncture needle 3 during operation. At the same time, this design also makes the insertion distance of the puncture needle 3 shorter, and ultimately enables the puncture process (out-of-plane insertion) to be completed more accurately and efficiently during the hot perfusion operation, reducing damage to the patient's tissue. Moreover, the smaller insertion angle and distance also make the entire hot perfusion operation more convenient, improving the operability and safety during the hot perfusion treatment process.

[0030] It should be noted that this application utilizes the puncture holder assembly 2 to combine a heated perfusion puncture needle with handheld ultrasound technology, i.e., the handheld ultrasound device serves as a navigation device for the heated perfusion puncture needle. This design eliminates the need for extensive modifications to existing heated perfusion equipment, but instead cleverly leverages the portability and real-time imaging capabilities of the handheld ultrasound device to precisely guide the puncture needle during operation.

[0031] Specifically, combined Figure 4-Figure 6 As shown, the first connecting portion 202 is provided with a limited opening 203, the first end of the connecting screw 5 is rotatably connected to the second connecting portion 212, and the second end of the connecting screw 5 is connected to the fastening nut 6;

[0033] The second end of the connecting screw 5 is provided with a limiting cap 50. The fastening nut 6 is provided with a third connecting portion 60 and a slot 61. The third connecting portion 60 is in communication with the slot 61. The connecting screw 5 is threadedly connected to the third connecting portion 60, and the limiting cap 50 is retained within the slot 61.

[0035] Specifically, combined Figure 2-Figure 5 As shown, a first limiting groove 11 and a first limiting protrusion 13 are respectively provided on the outer side wall of the probe 10;

[0036] The inner side wall of the first support arm 200 and / or the third support arm 210 is provided with a second limiting protrusion 22 that engages with the first limiting groove 11;

[0037] The inner side wall of the second support arm 201 and / or the fourth support arm 211 is provided with a limiting notch 213 which engages with the first limiting protrusion 13;

[0038] Furthermore, a first retaining flange 12 is provided on the outer sidewall of the probe 10, and a second retaining groove 23 is provided on the inner sidewall of the first bracket 20 and / or the second bracket 21 to engage with the first retaining flange 12.

Furthermore, the puncture needle assembly is also easy to disassemble. By using the handheld ultrasound device to detect the puncture needle, the relative position of the puncture needle and its surrounding tissues can be displayed in real time, allowing the doctor to accurately guide the puncture needle to the target area, thereby ensuring the accurate delivery of therapeutic drugs and improving the accuracy and effectiveness of treatment. Furthermore, through ultrasound images, the doctor can clearly observe the tissues along the puncture needle's path, thereby avoiding damage to these tissues during the puncture process. This reduces the risk during treatment, ensures patient safety, and improves the comfort level during treatment.
