Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment and relates to an ultrasonic treatment device, in particular to an endoscopic straight-rod curved surface scanning treatment head. Background Art

[0002] Chronic cervicitis is a common gynecological disease, and 60% to 80% of women of childbearing age have suffered from this disease. At present, the main methods of physical treatment for chronic cervicitis are: laser therapy, cryotherapy, infrared coagulation therapy, microwave therapy, cervical loop electrosurgical excision surgery and focused ultrasound therapy. Except for focused ultrasound therapy, these physical treatment methods are aimed at destroying the cervical lesions from the outside of the skin to the inside of the deep tissue, allowing the surrounding normal squamous epithelium to grow toward the cervical canal opening to achieve the purpose of covering the wound. However, these physical treatment methods have the following disadvantages:

[0003] (1) The treatment depth is not deep enough, it is difficult to destroy deep lesions, the treatment is not thorough, and the possibility of recurrence is high;

[0004] (2) Damage to the cervical epidermis produces scars, destroying the normal cervical structure and making it difficult to repair;

[0005] (3) Scar formation causes cervical stenosis, increasing the possibility of cervical dystocia and infertility;

[0006] (4) There are many side effects after treatment, including large amounts of vaginal discharge, scab shedding, bleeding, etc.

[0007] Focused ultrasound therapy is a method of focusing low-energy ultrasound from outside the body through tissues on the target area. The thermal effect generated by the ultrasound extends from the deep side of the tissue to the shallow side, directly destroying pathogens (streptococci, staphylococci, enterococci, gonococci, Chlamydia trachomatis, HPV, etc.) and their products. Under the action of ultrasound of the same energy intensity, inflammatory infiltrating cells and diseased tissues are first damaged or destroyed, while the normal cervical structure is preserved, and the tissue can restore normal elasticity and function. While focusing ultrasound treats damaged lesions, it can also improve local tissue microcirculation and enhance local tissue immune function.

[0008] At present, focused ultrasound treatment uses an endoscopic straight-rod treatment head, whose treatment body extends through the vagina to the cervix, adjusts the ultrasound focus plane output by the treatment body, and thus uses focused ultrasound to treat the lesion area of ​​the cervix. During treatment, the operator needs to hold the endoscopic straight-rod treatment device and move it within the range of the upper surface of the cervix in the patient's body (circular area with a diameter of about 30 to 40 mm). However, this endoscopic straight-rod treatment head still has some disadvantages: the operator cannot observe the condition of the patient's cervix during the treatment process, that is, an endoscope and other equipment are required to determine the lesion area, and then adjust the ultrasound focus plane to achieve it; the endoscopic straight-rod treatment device cannot move evenly on the annular involute of the upper surface of the cervix in the patient's body, which will cause the endoscopic straight-rod treatment device to have a certain degree of blindness in treatment, which is very likely to cause omission of treatment points, too long treatment time for individual points, and overlapping treatment points. Too long treatment time for individual points and overlapping treatment points will cause overtreatment, which will destroy the normal cervical structure and make it difficult to repair; omission of treatment points makes the treatment incomplete, and chronic cervicitis cannot be cured.

[0045] The present invention is now further described in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0046] like Figure 1 to Figure 3 As shown, an endoscopic straight-rod treatment head includes a shell 1, one end of which forms a handle portion for an operator to hold; the other end of the shell 1 is open, and a support assembly 2 is fixed to the inner wall of the shell 1 near the opening, and a sound-transmitting cover 3 is arranged on the opening, and a cavity is formed between the support assembly 2 and the sound-transmitting cover 3 for containing coupling water to form a water bag; a focusing transducer 4 is arranged in the cavity, and the focusing transducer 4 is connected to one end of a crank assembly 5, and the other end of the crank assembly 5 is connected to a rotating assembly 6, and the rotating assembly 6 is connected to a lifting assembly 7, so that the crank assembly 5 drives the focusing transducer 4 to rotate and swing in the entire cavity, thereby realizing uniform scanning of the involute surface or the annular surface.

[0047] The sound-transmitting cover 3 is a hard shell cover with a spherical curved surface structure to ensure that the focusing transducer 4 is fully coupled with the coupling water in the cavity; a control panel 8 is provided on the handle part to facilitate opening, closing and related visual operations; a cable inlet is provided on the end surface of the handle part, which is arranged on the end surface and does not affect the operator's operation. A sound-transmitting cover 3 with a thin film plane is added or adopted behind the sound-transmitting cover 3, and the sound-transmitting cover 3 can be a disposable design for easy replacement.

[0048] The housing 1 is composed of a handle housing 11 and a straight rod housing 12 assembled together. The straight rod housing 12 includes an outer shell and an inner shell. A symmetrically distributed circulating water channel 13 is formed between the outer shell and the inner shell to form an elliptical cross section of the straight rod housing 12. Figure 4 As shown. The outer shell and inner shell mentioned here are equivalent to the straight rod outer shell 12 having an outer layer and an inner layer, and the circulating water channel 13 is located between the outer layer and the inner layer. In actual manufacturing, the diameter of the outer shell 1 is 20 to 40 mm, and the optimal diameter is 35 mm to 25 mm. The elliptical straight rod outer shell 12 is relatively fixed to the position of the cervix in the patient's body, providing treatment coordinate positioning for treatment planning. One end of the circulating water channel 13 is located in the cavity, and the other end of the circulating water channel 13 is located on the end surface of the handle.

[0049] Furthermore, other channels are provided between the outer shell and the inner shell, and imaging equipment, lighting equipment, etc. can be provided in the other channels. The imaging equipment is specifically a medical miniature camera plus a cable, and the lighting equipment is a light-emitting conductor, which can be provided together with the imaging equipment or separately provided in the channel. More specifically, the miniature camera can be placed on one side of the front end of the treatment head, and the light-emitting body can be provided on the other side of the front end.

[0050] like Figure 4 As shown, the support assembly 2 includes a support frame 21 and a mounting plate 22. The support frame 21 is tightly fitted on the inner wall of the inner shell. A through hole is provided in the middle of the support frame 21 for the second connecting rod 52 to pass through. A flange 211 is formed on the upper edge of the support frame 21. The mounting plate 22 is limited in the flange 211 and is connected to the support frame 21 by bolts. A matching hole is provided in the middle of the mounting plate 22 to accommodate the rotation of the universal rotating member 521.

[0051] like Figure 3 and Figure 5 As shown, the crank assembly 5 includes a connecting rod 1 51 and a connecting rod 2 52 which are hinged together. When the connecting rod 1 51 and the connecting rod 2 52 are in a straight line, the focusing transducer 4 is located at the bottom of the cavity, and the connecting rod 2 52 is provided with a universal rotating member 521 (spherical structure) rotating on the supporting assembly 2. Of course, the crank assembly 5 can also be composed of more connecting rods (for example, 3), but the angle between each section of the connecting rod, the relationship between the length of the straight rod housing 12, and the swing of the focusing transducer 4 need to be considered.

[0052] like Figure 4 and Figure 5 As shown, the lifting assembly 7 is arranged in the handle housing 11, and includes a lifting stepping motor 71, a reducer 72 and a lifting screw 73. The lifting stepping motor 71 is connected to the reducer 72, and the output end of the lifting stepping motor 71 is connected to the lifting screw 73. The lifting screw 73 extends into the straight rod housing 12 and is provided with a threaded sleeve 74 that moves back and forth along it, and the threaded sleeve 74 is connected to the mounting seat 60 of the rotating assembly 6. A lifting guide rail 121 is protrudingly provided on the inner wall of the inner shell of the straight rod housing 12, and a slide groove 601 that slides along the lifting guide rail 121 is provided on the side wall of the mounting seat 60. The lifting stepping motor 71 rotates, driving the lifting screw 73 to rotate, and the threaded sleeve 74 drives the mounting seat 60 to move back and forth along the lifting screw 73. At the same time, the mounting seat 60 slides along the lifting guide rail through the slide groove 601 to ensure the stability of the lifting of the mounting seat 60.

[0053] like Figure 3 to Figure 5 As shown, the rotating assembly 6 includes a rotating motor 61 and an adapter 62 . The rotating motor 61 is connected to the mounting seat 60 . The output shaft of the rotating motor 61 is connected to the adapter 62 . One end of the adapter 62 is hinged to one end of the crank assembly 5 .

[0054] The lifting stepper motor 71 and the reducer 72 form a lifting device, a rotating motor 61 (stepping motor), a secondary crank connecting rod, and a focusing transducer 4 to form a mechanical structure for rotating the crank connecting rod. The mechanical structure is contained in a shell composed of an elliptical shell 1 and a spherical hard shell sound-transmitting cover 3. The lifting device bends the secondary crank connecting rod to make the focusing transducer 4 and the central axis of the treatment head produce a deflection angle, and the rotating motor 61 rotates to produce a circular scan, and the combination of the two realizes involute curved surface scanning. The circulating water channels 13 on both sides of the elliptical straight rod shell 12 provide circulating degassed water for the sound-transmitting cover 3, and the circulating degassed water fills the spherical hard shell sound-transmitting cover 3, and the focusing transducer 4 swings and rotates in the cavity. During treatment, the sound-transmitting cover 3 has good acoustic coupling with the patient's cervical epidermis. When the swing angle of the focused transducer 4 is 0 degrees, that is, when its axis coincides with the central axis of the treatment head, it is the deepest treatment depth of the curved surface treatment; when the swing angle of the focused transducer 4 is the maximum, that is, when the angle between its axis and the central axis of the treatment head is the largest, the focused treatment is at the edge of the treatment head, which is the shallowest treatment depth of the curved surface treatment.

[0055] Automatic treatment: according to the patient's condition, set the height range of the lifter, the treatment speed of the rotary motor 61 and the ultrasonic energy. Figure 6 As shown, after the treatment head completes good acoustic coupling with the cervical surface, the automatic treatment button is activated through the control panel 8, and the treatment head realizes complete involute (annular) surface scanning treatment from outside to inside (or from inside to outside). The involute (annular) surface is as shown in FIG. Figure 6 As shown in the invisible part, the device stops working automatically after the scanning is completed. Among them, the height of the lifter controls the deflection angle between the focusing transducer 4 and the central axis of the treatment head, and the rotation of the rotary motor 61 drives the focusing transducer 4 to move in an annular manner. The combination of the two realizes involute (annular) curved surface scanning.

[0056] Single ring treatment: according to the patient's condition, set the height of the lifter, the treatment speed of the rotary motor 61 and the ultrasonic energy. Figure 7 As shown, after the treatment head has completed good acoustic coupling with the cervical surface, the automatic treatment button is activated through the control panel 8, and the treatment head performs a complete annular scanning treatment. Figure 7 As shown in the shaded area, the device stops working automatically after the scanning is completed. The height of the lifter controls the deflection angle between the focusing transducer 4 and the central axis of the treatment head, and the rotary motor 61 rotates the transducer in a circular motion.

[0057] Shape-following treatment: According to the condition of the patient, the treatment area and ultrasonic energy are selected, and the height of the elevator and the position of the rotating motor 61 are configured. After the treatment head completes good acoustic coupling with the cervical surface, the treatment button is activated through the control panel 8, and the treatment head realizes scanning treatment of the shape-following area, and the device automatically stops working after the scanning is completed. Among them, the height of the elevator controls the deflection angle between the focusing transducer 4 and the central axis of the treatment head, and the rotating motor 61 controls the annular coordinate position of the focusing transducer 4. Among them, the central single point treatment, that is, the deflection angle between the focusing transducer 4 and the central axis of the treatment head is 0.

[0058] As another implementation method, Figure 8 As shown (the state where the housing 1 is removed), the input end of the lifting stepper motor 71 is connected to a manual adjustment member 711 extending out of the handle housing 11, and the manual adjustment member 711 can be manually operated to adjust the height of the rotating motor 61, thereby changing the bending degree of the crank assembly 5, that is, changing the deflection angle between the focusing transducer 4 and the central axis of the treatment head. Of course, the lifting stepper motor 71 can also be eliminated, and a worm gear structure can be adopted, the torsion plate 711 shaft is connected to the worm gear, the worm gear is meshed with the worm gear, the worm gear is connected to the lifting screw 73, and the worm gear is installed on a mounting frame through a bearing, and the mounting frame is set on the inner wall of the handle housing 11.

[0059] The above-mentioned implementation mode is only for illustrating the technical concept and features of the utility model, and its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
