[0002] Interventional ultrasound technology, a branch of modern ultrasound medicine, is a new technology developed based on ultrasound imaging to further meet the needs of clinical diagnosis and treatment. During interventional ultrasound procedures, various ultrasound puncture probes and puncture frames attached to the probes are tools of interventional ultrasound, offering greater precision and a higher success rate compared to manual puncture. However, different puncture sites require different needle insertion angles, necessitating puncture frames with varying angles. Currently, hospitals use non-adjustable puncture frames in various sizes, selecting the appropriate size based on the specific needs, but the angle cannot be arbitrarily adjusted, making it inconvenient to use. To accommodate different puncture angle requirements, an adjustable puncture frame is needed. Utility Model Content

[0023] A specific embodiment, as shown in the figure, represents a preferred embodiment of this utility model. A simple puncture frame with adjustable needle insertion angle mainly includes a housing 2, which is fitted onto the lower end of an ultrasonic probe 1. The upper and lower ends of the housing 2 are open. The front of the housing 2 has an inwardly inclined slope. The back and two sides of the housing 2 are parallel to a vertical plane. The inclined slope fits against the lower end of the front of the ultrasonic probe 1. A latch 12 is provided on the inclined slope. A protrusion 13 at the lower end of the front of the ultrasonic probe 1 is movably engaged within the latch 12. A connecting hole is provided on the back of the housing 2. A connecting stud 16 is threaded onto the connecting hole. One end of the connecting stud 16 is connected to a washer 17, and the other end of the connecting stud 16 is connected to a handle 14 for rotation. One end of the washer 17 abuts against the back of the ultrasonic probe 1. The lower end of the inclined surface of the casing 2 is provided with a protruding strip 10. The length direction of the protruding strip 10 is parallel to the lower end face of the casing 2. A rotating hole is provided on the protruding strip 10. A rotating shaft is rotatably connected to the rotating hole. Both ends of the rotating shaft are vertically connected to connecting rods 9. The two connecting rods 9 are symmetrically arranged. A connecting plate 4 is installed between the two connecting rods 9. Angle rulers 3 are installed on both sides of the connecting plate 4. Arc-shaped sliding holes are provided on both sides of the casing 2. The angle rulers 3 are slidably connected to the sliding holes. A fixing hole is provided on the side of the casing 2. The fixing hole communicates with the sliding hole. A fixing stud is threadedly connected to the fixing hole. The end face of the fixing stud abuts against the angle ruler 3 in the sliding hole. A pin seat 5 is detachably connected to the outer plate surface of the connecting plate 4.

[0024] In specific implementation of this invention, to ensure a better fit between the housing 2 and the ultrasound probe 1, the structure of the housing 2 is designed according to the structure of the ultrasound probe 1. Therefore, the housing 2 has an inclined surface. When the housing 2 is fitted onto the ultrasound probe 1, the inner side of the inclined surface fits against the front of the ultrasound probe 1. The existing ultrasound probe 1 has a protrusion 13, which is detachably connected to the existing puncture frame. Without changing the structure of the existing ultrasound probe 1, a slot 12 is provided on the inclined surface of the housing 2. Since the size of the housing 2 is larger than the size of the lower end of the ultrasound probe 1, it is convenient for the housing 2 to be fitted from the lower end of the ultrasound probe 1. The protrusion 13 of the ultrasound probe 1 is engaged in the slot 12 of the housing 2, and the protrusion 13 extends out of the housing 2 from the slot 12. Therefore, the inclined surface of the housing 2 fits better against the front of the ultrasound probe 1. Then, a connecting stud 16 is threaded into the connecting hole of the housing 2, and the washer 17 of the connecting stud 16 abuts against the back of the ultrasound probe 1, fixing the housing 2 onto the ultrasound probe 1. A rotating shaft is rotatably connected to the rotating hole of the protrusion 10 on the housing 2. A connecting plate 4 is installed between the two connecting rods connected to the rotating shaft. The connecting plate 4 is slidably connected in the sliding hole on the housing 2 through the angle gauge 3. It is threadedly connected to the fixing hole on the housing 2 using a fixing stud. The fixing stud abuts against the angle gauge 3, and the angle of the connecting plate 4 is fixed by the angle gauge 3. The placement angle of the connecting plate 4 is set by the angle gauge 3, and the needle seat 5, which is detachably connected to the connecting plate 4, is used to set the insertion angle of the puncture needle.

[0025] Because puncture requires strict hygiene control, the needle hub 5, which comes into contact with the puncture needle, must be kept strictly hygienic. For ease of use, the needle hub 5 is detachably connected to the connecting plate 4, allowing for easy removal for disinfection or replacement. Furthermore, the needle hub 5 is a disposable product made of silicone, the same material as existing puncture frames; it can be removed and discarded after each use. To facilitate removal of the needle hub 5, the connecting plate 4 has multiple insertion holes, and multiple insertion blocks 7 are mounted on the back of the needle hub 5. These insertion blocks 7 are movably inserted into the insertion holes. A syringe 8 is located on the front of the needle hub 5. When the needle hub 5 is mounted on the connecting plate 4, the length direction of the syringe 8 is perpendicular to the length direction of the protrusion 10. The syringe 8 has a side opening 15, which is parallel to the length direction of the syringe 8. When needed, the insertion blocks 7 on the needle hub 5 are inserted into the insertion holes on the connecting plate 4 to fix and limit the needle hub 5. Furthermore, the insert 7 is made of elastic silicone. When inserted into the insertion hole, the insert 7 deforms, allowing it to be inserted into the insertion hole. The puncture needle is inserted into the syringe 8 of the needle holder 5. The syringe 8 limits the angle of the puncture needle. After the puncture needle is inserted, it detaches from the syringe 8 through the side opening 15.

[0026] There are other ways to connect the needle holder 5 to the connecting plate 4. Further, the outer surface of the connecting plate 4 has a protruding locking block 18, on which the needle holder 5 is movably engaged. The back of the needle holder 5 has a locking groove 19, which is movably engaged with the locking block 18. A syringe 8 is mounted on the front of the needle holder 5. When the needle holder 5 is mounted on the connecting plate 4, the length direction of the syringe 8 is perpendicular to the length direction of the protrusion 10. The syringe 8 has a side opening 15, which is parallel to the length direction of the syringe 8. Further, the locking block 18 has the same structure as the protrusion 13 of the original ultrasound probe 1. The needle holder 5 can be connected to the locking block 18 using one of the existing specifications of puncture needles. After connection, the angle can be adjusted using the connecting plate 4 and the angle ruler 3. Because an existing puncture frame is used, it is not necessary to remanufacture the needle holder 5, reducing manufacturing costs.

[0027] Because the syringe 8 is relatively small, a guide plate is further provided at the upper end of the syringe 8 to facilitate the insertion of the puncture needle. The guide plate is an arc-shaped plate 6 that is wider at the top and narrower at the bottom, and an opening is provided on the guide plate. The opening is aligned with the side opening 15. The arc-shaped plate 6 allows the puncture needle to enter the syringe 8 more easily and then exit the syringe 8 through the opening and the side opening 15.

[0028] Furthermore, the flat surface of the gasket 17 is provided with a silicone pad, which increases the friction and plays a buffering role.

[0029] Furthermore, the inner surface of the housing 2 is provided with cushioning pads to protect the ultrasonic probe 1 from wear.

[0030] Furthermore, a nut 11 is installed on the outer end of the fixing stud to facilitate rotation of the fixing stud.

[0031] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
