Description

Technical Field

[0001] This utility model relates to the field of ultrasonic therapy equipment technology, and in particular to a water-circulating focused ultrasound superficial tissue cervical treatment gun. 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 superficial tissue cervical treatment gun has an outer tube, a water balloon, a transducer, etc. Existing ultrasound treatment equipment for cervical treatment guns has the following drawbacks:

[0005] 1. The transducer of the treatment gun is prone to overheating and damage during treatment, which affects the treatment effect and the product's lifespan;

[0006] 2. The positional relationship between the water-filled balloon and the transducer in the cervical treatment gun has a significant impact on the treatment effect;

[0007] 3. Existing treatment guns have water pipes, electrical wires, coaxial cables, etc. arranged separately, which makes changing the treatment gun cumbersome and involves multiple strands of wire.

[0008] 4. The ordinary plugs and sockets currently in use have obvious shortcomings in terms of safety, durability, applicability and maintenance costs, and therefore cannot provide sufficient reliability for the equipment, affecting the overall stability and efficiency of the equipment.

[0009] 5. The outer tube of the existing treatment gun needs to be quickly replaced before or after treatment to improve treatment efficiency. At the same time, it is very important that the outer tube can be quickly removed in emergency situations, such as when the patient experiences adverse reactions or needs to stop treatment immediately. Summary of the Invention

[0010] 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 water-circulating focused ultrasound superficial tissue cervical treatment gun is provided.

[0011] The technical solution adopted by this utility model to solve its technical problem is: a water-circulating focused ultrasound superficial tissue cervical treatment gun, including a handle, an outer tube and an inner tube, wherein the handle is a hollow structure and a printed circuit board is installed in the inner cavity of the handle;

[0012] The head of the handle is rotatably mounted with an outer tube, which is hollow. An inner tube is installed inside the outer tube, and an inner drain pipe and an inner water inlet pipe are installed inside the inner tube. Transducers are installed at the ends of the inner drain pipe and the inner water inlet pipe. A sound-permeable membrane is installed on the end face of the outer tube and is locked to the outer tube by fasteners.

[0013] The handle has a cable installed at the tail, and the inner drain pipe and inner water inlet pipe are respectively connected to the outer water inlet pipe and outer drain pipe in the cable, bypassing the printed circuit board.

[0014] The cable is equipped with a self-locking quick-connect plug and socket at the end.

[0015] Furthermore, the handle has a hollow structure, and a knob-type depth adjustment device is installed in the inner cavity of the handle. The knob-type depth adjustment device includes a threaded component and a threaded rotating buckle. The threaded component is sleeved on the inner tube and is pinned by a pin. The outer peripheral wall of the threaded component extends out of the handle. The threaded rotating buckle is sleeved on the handle and is threadedly engaged with the threaded component extending out of the handle.

[0016] Furthermore, the distance between the transducer and the acoustic membrane in the focused ultrasound superficial tissue cervical treatment gun is adjusted to 1–4 mm by the knob-type depth adjustment device.

[0017] Furthermore, the handle includes a handle body, on which an annular groove is provided. At the bottom of the annular groove, an opening communicating with the inner cavity of the handle body is provided. The openings are symmetrically arranged, and the outer peripheral wall of the threaded component extends out from the opening.

[0018] Furthermore, the threaded part includes a cuboid portion and an arc portion. Both ends of the cuboid portion are provided with arc portions, and the outer arc surface of the arc portion is provided with an external thread portion. The external thread portion extends beyond the opening of the handle. The cuboid portion is provided with a through hole in the axial direction and a pin hole in the longitudinal direction.

[0019] Furthermore, the threaded part has a trapezoidal thread, and the cuboid part of the threaded part and the opening of the handle are in transition or interference fit.

[0020] 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; the threaded rotary buckle includes a first part and a second part, one part has a locking head at the edge of the connecting surface, and the other part has a corresponding buckle at the edge of the connecting surface, and the first part and the second part are joined together as a whole by inserting the locking head into the buckle.

[0021] Furthermore, the cable includes an external water inlet pipe, an external drain pipe, a power cord, and a coaxial cable. The external water inlet pipe and the external drain pipe are located in the middle and are arranged side by side. A coaxial cable and part of the power cord are installed at the junction of the external water inlet pipe and the external drain pipe. Another part of the power cord is installed above the coaxial cable. A filler layer is used to fill the gap between the power cord and the aluminum foil layer of the cable.

[0022] Furthermore, the cable is covered with an aluminum foil layer, which is then covered with a sheath layer. Between the aluminum foil layer and the sheath layer, a braided shielding layer and a non-woven fabric layer are sequentially wrapped from the inside out.

[0023] Furthermore, the power cord includes a conductor and an insulating layer, the outer periphery of which is covered by the insulating layer.

[0024] The beneficial effects of this utility model are:

[0025] 1. This utility model forms a water circulation in the treatment gun by connecting the inlet pipe and the outlet pipe, which effectively prevents the transducer from being damaged during treatment, thereby improving the treatment effect and product lifespan.

[0026] 2. The rotary depth adjustment device in the focused ultrasound superficial tissue cervical treatment gun allows for pre-adjustment based on clinical conditions or adjustment of the transducer and water balloon distance during treatment. This facilitates clinical treatment by doctors and improves treatment effectiveness.

[0027] 3. The cable integrates the water pipe, power cord, and coaxial cable into one piece, eliminating the hassle of changing the treatment gun and reducing the trouble of multiple strands of wire.

[0028] 4. Self-locking quick-connect plugs and sockets prevent water from flowing out and causing short circuits when plugging and unplugging. The self-locking quick-connect design makes installation and removal convenient and avoids the risk of accidentally knocking the socket off.

[0029] 5. The outer tube is quick-connected by rotation, and the outer tube is sterile, making it easy for doctors to remove and install. Attached Figure Description
