Description

Technical Field

[0001] This utility model relates to the field of ultrasound therapy technology, and in particular to a focused ultrasound superficial tissue cervical treatment gun with a knob-type depth adjustment device. Background Technology

[0002] The focused ultrasound superficial tissue cervical treatment gun is a medical device that uses high-energy focused ultrasound (HIFU) technology to treat cervical-related diseases. Its most significant feature is its "inside-out" treatment approach, meaning it treats from the deep part of the lesion to the superficial layer while preserving the surface tissue.

[0003] By taking advantage of the differences in the sensitivity of different tissues to ultrasound, under the same energy intensity, inflammatory infiltrating cells and lesions under the cervical mucosa are damaged or destroyed first, while normal cervical stromal tissue can be preserved intact.

[0004] The focused ultrasound (FUS) cervical treatment gun for superficial tissue consists of an outer rod, a water-filled balloon, and a transducer. The positional relationship between the water-filled balloon and the transducer significantly impacts the treatment outcome. Current ultrasound treatment equipment for cervical tissue can only adjust the outer rod during treatment, which limits the available space in the cervix. If the distance between the water-filled balloon and the transducer is too great, the following consequences may occur:

[0005] 1. The focused ultrasound energy generated by the transducer needs to be transmitted to the treatment area through the water bag. If the distance between the two is too far, some energy will be lost during the transmission process, resulting in less energy reaching the lesion and affecting the treatment effect;

[0006] 2. The position of the water bag determines the focal point of the ultrasound waves emitted by the transducer. If the distance between the water bag and the transducer is not appropriate, the focal point may deviate from the target area, reducing the accuracy of the treatment.

[0007] 3. If the distance between the water bag and the transducer is too far, the surrounding normal tissue will receive too much energy, increasing the risk of side effects such as tissue damage or pain. At the same time, the position of the water bag directly affects the temperature and energy distribution in the treatment area, which may also lead to poor treatment results or even require repeated treatment.

[0008] Therefore, there is an urgent need for a cervical treatment gun that can adjust the distance between the transducer and the water bag inside the treatment gun. Summary of the Invention

[0009] The technical problem to be solved by this utility model is: in order to solve the problems existing in the prior art in the background art, a focused ultrasound superficial tissue cervical treatment gun with a knob-type depth adjustment device is provided, which can pre-adjust the distance between the transducer and the water bag inside the treatment gun according to the patient's body characteristics (weight, etc.).

[0016] Furthermore, the threaded part has a trapezoidal thread.

[0017] Furthermore, the cuboid portion of the threaded part and the opening of the handle are in a transition or interference fit.

[0018] Furthermore, the outer surface of the threaded rotary buckle has threaded protrusions, and the inner surface of the threaded rotary buckle has an internal thread portion that mates with the threaded component.

[0019] Furthermore, the threaded rotary buckle includes a first part and a second part. One part has a locking head at the edge of its connecting surface, and the other part has a corresponding buckle at the edge of its connecting surface. The first part and the second part are joined together as a whole by inserting the locking head into the buckle.

[0020] Furthermore, it also includes a water bladder and a transducer, with the water bladder installed at the end of the outer rod and the transducer installed at the end of the inner rod.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0032] Example 1:

[0033] like Figures 1-7The illustrated focused ultrasound superficial tissue cervical treatment gun with a knob-type depth adjustment device includes a handle 1. An outer rod 2, made of 0.5mm thick medical-grade stainless steel, is mounted at one end of the handle 1 for fixing and guiding, allowing for precise guidance. An inner rod 3 is installed within the inner cavity of the outer rod 2. The handle 1 has a hollow structure, and a knob-type depth adjustment device is installed within its inner cavity.

[0034] The knob-type depth adjustment device includes a threaded component 4 and a threaded rotating buckle 5. The threaded component 4 is sleeved on the inner rod 3 and pinned by a pin 6. The outer peripheral wall of the threaded component 4 extends out of the handle 1. The threaded rotating buckle 5 is sleeved on the handle 1 and threadedly engages with the threaded component 4 extending out of the handle 1.

[0035] The distance between the transducer and the water balloon in the focused ultrasound superficial tissue cervical treatment gun, which is adjusted by a knob-type depth adjustment device, is 1-4 mm. The original distance from the water balloon 15 is 0.5 mm. The four adjustment positions are 1.5 mm, 2.5 mm, 3.5 mm, and 4.5 mm, respectively.

[0036] like Figure 6 As shown, the handle 1 includes a handle body, and the handle body has an annular groove 7. The bottom of the annular groove 7 has an opening 8 that communicates with the inner cavity of the handle body. The openings 8 are symmetrically arranged, and the outer peripheral wall of the threaded part 4 extends out from the opening 8.

[0037] like Figure 3 As shown, the threaded part 4 has a trapezoidal thread, which rotates smoothly. The threaded part 4 includes a cuboid part and an arc part. Both ends of the cuboid part are provided with arc parts. The outer arc surface of the arc part is provided with an external thread part 10.

[0045] Step 2: Snap the rotating buckle 5 onto the trapezoidal threaded part 4;

[0046] Step 3: Before treatment, rotate the rotating buckle 5 to adjust the threaded part 4. The threaded part 4 pushes the inner rod 3 to adjust the depth to 4 levels. Set the depth by rotating the rotating buckle 5 to adjust the distance between the transducer 14 and the water bag 15. Confirm the depth by rotating the scale mark 13.

[0047] Example 2:

[0048] The difference from Embodiment 1 is that the threaded rotating buckle 5 includes a first part 51 and a second part 52. The connecting surface edge of the second part 52 is provided with a buckle head 53, and the connecting surface edge of the first part 51 is provided with a corresponding buckle 54. The first part 51 and the second part 52 are joined together as a whole by inserting the buckle head 53 into the buckle 54.

[0049] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
