Description

Technical Field

[0001] The present invention relates to the field of medical equipment treatment, and in particular to an ultrasonic treatment head. The present invention also relates to an ultrasonic treatment device comprising the ultrasonic treatment head. Background Art

[0002] Ultrasound therapy uses ultrasound to produce significant mechanical and thermal effects on human tissues. It can not only accurately diagnose patients' diseases, but also provide precise puncture and minimally invasive treatment for patients. Taking minimally invasive treatment as an example, during the treatment process, with the help of the physical properties of ultrasound such as tissue penetration and focusability, low-energy ultrasound waves outside the body are focused on the target area inside the body. Through the effects of high temperature produced by high-intensity ultrasound at the focus, the tissues inside the target area are completely destroyed without damaging tissues outside the target area, thus achieving non-invasive removal of target tissues.

[0003] In actual treatment, the target area of ​​treatment is often located at different depths. The operator needs to frequently replace gel pads of different specifications. Gel pads of different specifications correspond to target areas of different depths, which makes the operation more cumbersome. A small number of existing ultrasonic treatment devices are equipped with a coupling device, and a focal length adjustment unit is provided in the coupling device, so that the ultrasonic wave in the coupling device changes its propagation direction with the help of the focal length adjustment unit, so that the penetration depth of the ultrasonic wave focus changes, and the ultrasonic wave is set at target areas of different depths. This focal length adjustment unit includes a plurality of liquid capsules filled with coupling fluid, and different liquid capsules are isolated from each other. The ultrasonic wave propagates at different speeds in different liquid capsules, so that the ultrasonic wave changes the penetration depth of the focus through multiple refractions. However, the penetration depth of the ultrasonic wave focus is easily affected by factors such as the volume and viscosity of the coupling fluid in each liquid capsule, and the adjustment accuracy is low. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide an ultrasonic treatment device and an ultrasonic treatment head, which utilize a gear transmission mechanism to adjust the focus of all detection blocks to move along the center line of the gel pad, thereby achieving precise adjustment of the penetration depth with high adjustment accuracy.

[0015] Preferably, it also includes an outer shell with a support frame inside and a gland ring covering the outer circumference of the gel pad and used to fix the gel pad placed on the support frame to the outer shell.

[0016] Preferably, an abutment flange is integrally provided at the end of the gel pad, and a stop flange abutting against the abutment flange is integrally provided on the inner wall of the center hole of the gland ring.

[0017] Preferably, mutually engaging teeth and engaging grooves are provided between the clamping sleeve of the gland ring and the connecting sleeve of the outer shell.

[0019] Preferably, it also includes:

[0020] a drive motor for providing power to the drive train;

[0025] When the driving wheel train rotates, the driving wheel train drives all the transmission wheel trains to rotate synchronously, and each set of transmission wheel trains drives the detection blocks connected to it to swing, changing the detection angle of each detection block. Based on the special distribution of all the detection blocks, when the driving wheel train drives all the detection blocks to swing synchronously at a preset angle through the transmission wheel train, on the center line, the distance between the focus of all the detection blocks and the gel pad reaches a preset distance, which is the penetration depth of the ultrasonic treatment head, thereby achieving the adjustment of the penetration depth.

[0049] The embodiment of the present invention discloses an ultrasonic treatment head, which includes a plurality of detection blocks 11, a gel pad 5, a plurality of transmission gear trains and a drive gear train.

[0050] Any detection block 11 includes an insulating shell 111 and a plurality of piezoelectric crystals 112. The insulating shell 111 is disc-shaped and has a receiving groove in the center. The receiving groove can be a cylindrical groove. All piezoelectric crystals 112 are fixed to the receiving groove of the insulating shell 111 by means of insulating glue. The receiving groove is specifically equipped with seven piezoelectric crystals 112, one of which is fixed at the center of the receiving groove, and the other six piezoelectric crystals 112 are evenly distributed in a circular ring around the center of the receiving groove. The insulating glue can be epoxy resin potting glue, but is not limited thereto. The piezoelectric crystal 112 can be a ceramic crystal that converts high-voltage electric pulses into ultrasonic waves, but the type of piezoelectric crystal 112 is not limited thereto.

[0051] The gel pad 5 covers the entire detection block 11, can fit the skin softly, and is made of sound-permeable material. The ultrasonic treatment head provided by the present invention also includes a transducer 1 for converting electrical energy into sound energy. The transducer 1 can use high-frequency ultrasound to clearly display lesions occurring in muscles, tendons, ligaments, peripheral nerves, and superficial soft tissues, so as to diagnose diseases of the musculoskeletal system. In order to make the gel pad 5 and the transducer 1 reliably cooperate, the gel pad 5 is provided with a groove that cooperates with the transducer 1. The end of the gel pad 5 away from the transducer 1 is a flat-headed conical structure, but its structure is not limited to this.

[0052] It should be particularly noted that all the detection blocks 11 are distributed according to a certain rule, all the detection blocks 11 are distributed along the concave spherical surface, and the focal points of all the detection blocks 11 converge on the center line of the gel pad 5 .

[0053] Several groups of transmission gear trains are connected to all the detection blocks 11 in a one-to-one correspondence, and the driving gear trains are meshed with all the transmission gear trains to achieve power transmission.

[0054] When the driving wheel train rotates, the driving wheel train drives all the transmission wheel trains to rotate synchronously, and each group of transmission wheel trains drives the detection blocks 11 connected thereto to swing, thereby changing the detection angle of each detection block 11. Based on the special distribution of all the detection blocks 11, when the driving wheel train drives all the detection blocks 11 to swing synchronously at a preset angle through the transmission wheel train, the distance between the focus of all the detection blocks 11 and the gel pad 5 on the center line reaches a preset distance, and the preset distance is the penetration depth of the ultrasonic treatment head, thereby achieving the adjustment of the penetration depth. The preset angle refers to the distance between the focus of all the detection blocks 11 and the gel pad 5 on the center line when the ideal penetration depth is reached.

[0055] In summary, the ultrasonic treatment head provided by the present invention optimizes its own mechanical structure and utilizes a gear transmission mechanism for power transmission, thereby accurately adjusting its penetration depth with high adjustment accuracy.

[0057] Any set of transmission gear trains includes a double gear 9, and a transmission gear 91 and a driving bevel gear 92 are fixed at both ends of the double gear 9, respectively. The transmission gear 91 is meshed with the inner gear ring of the rotating gear plate 8, and the transmission gear 91 and the driving bevel gear 92 are fixedly connected through a transmission shaft, so that the rotating gear plate 8 drives the driving bevel gear 92 to rotate synchronously through the transmission gear 91. The axis of the transmission shaft is parallel to the center line of the gel pad 5. Any set of transmission gear trains also includes a driven bevel gear 10, one end of the driven bevel gear 10 is meshed with the driving bevel gear 92, and the other end thereof is fixedly connected to the detection block 11 through a connecting shaft 12, so that the driving bevel gear 92 drives the detection block 11 to swing synchronously through the driven bevel gear 10. The connecting shaft 12 is rotatably mounted on the support column 32, and the connecting shaft 12 is perpendicular to the center line of the support frame 3. The support column 32 is vertically arranged on the support frame 3, and the support column 32 is used to support the rotation of the connecting shaft 12.

[0058] A limiting member is provided between the connecting shaft 12 and the supporting column 32, and the limiting member is used to limit the axial movement of the connecting shaft 12. The limiting member can be a clamping spring installed on the connecting shaft 12, but is not limited thereto.

The gland ring 4 covers the outer periphery of the gel pad 5, the gel pad 5 passes through the gland ring 4, and the gel pad 5 is fixed to the outer shell 2 by the gland ring 4.

[0060] An abutment flange 51 is integrally provided at one end of the gel pad 5 close to the support frame 3, and a stop flange 41 is integrally provided on the inner wall of the center hole of the pressure cover ring 4. The end faces of the abutment flange 51 and the stop flange 41 abut against each other to prevent the gel pad 5 from axially moving relative to the support frame 3, so that the gel pad 5 is tightly pressed against the support frame 3.

[0061] The gland ring 4 is fixed on the outer shell 2. The gland ring 4 includes a clamping sleeve 42 vertically connected to the stop flange 41. The top of the outer shell 2 is integrally fixed with a connecting sleeve, and the clamping sleeve 42 is sleeved on the outer periphery of the connecting sleeve.

[0062] The ultrasonic treatment head provided by the present invention also includes a driving motor 6 and a controller, and the driving motor 6 is used to provide power for the driving gear train. The driving motor 6 can specifically be a servo motor. The controller is connected to the driving motor 6. When the controller receives an input of a preset distance equal to the preset penetration depth, the controller controls the driving motor 6 to rotate along a preset direction at a preset angle, and the driving motor 6 drives all the detection blocks 11 to automatically and synchronously swing at a preset angle through the transmission gear train, so that the detection blocks 11 can realize automatic swinging, and the degree of automation and control accuracy are both high. The preset distance can be input into the controller through a terminal such as a display screen.

[0063] The working principle of the ultrasonic treatment head provided by the present invention is as follows:

[0064] Start the driving motor 6, which rotates clockwise. The driving motor 6 drives the rotating toothed disc 8 to rotate clockwise through the driving gear 7. The rotating toothed disc 8 drives all the driven gears to rotate counterclockwise. The driven gear drives the driving bevel gear 92 connected thereto to rotate counterclockwise synchronously. The driving bevel gear 92 drives the driven bevel gear 10 to rotate clockwise. The driven bevel gear 10 drives the detection block 11 connected thereto to swing downward. The focal points of all the detection blocks 11 move along the center line of the gel pad 5 toward the direction close to the gel pad 5, and the penetration depth decreases. On the contrary, the detection blocks 11 swing in the opposite direction, and the penetration depth increases.
