Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an irradiation head assembly and its millimeter-wave therapy device. Background Technology

[0002] In current millimeter-wave therapy devices, the treatment head, which is part of the irradiation head assembly, is usually aimed directly at the patient's treatment area during treatment. Sometimes, to improve the treatment effect, the treatment head is usually close to or directly attached to the patient's skin. However, when the patient's treatment area is injured, the treatment head can obstruct the patient's view, making alignment difficult. Furthermore, the treatment head may touch the patient's wound, and direct exposure to the wound can easily cause secondary damage to the patient's wound. Summary of the Invention

[0003] The purpose of this invention is to provide an irradiation head assembly and its millimeter-wave therapy device, which can avoid secondary damage to the patient's trauma site and meet different usage needs.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an irradiation head assembly, comprising: a treatment head; a fixing frame, wherein the treatment head is disposed on the fixing frame; a support member, wherein the support member is used to connect with an external adjustable bracket; an alignment ring, wherein the alignment ring is used to correspond to the treatment site of the patient and is disposed on the support member; contact blocks, wherein multiple contact blocks are detachably disposed on the alignment ring, and the multiple contact blocks are evenly distributed around the circumference of the alignment ring axis; and a rotating assembly, wherein the rotating assembly is used to drive the fixing frame to rotate and drive the treatment head to correspond to the position of the alignment ring.

[0005] Furthermore, it also includes a support component, which can be used to fit and be placed at different positions on the alignment ring, supporting the sterile gauze used to cover the patient's wound.

[0006] Furthermore, the alignment ring is provided with multiple arc-shaped grooves, which are evenly distributed around the circumference of the alignment ring axis. The support component is used to fit in any two adjacent arc-shaped grooves.

[0007] Furthermore, the support assembly includes: two arc-shaped support plates that are adapted to an arc-shaped groove; and multiple arc-shaped rods of different sizes disposed between the two arc-shaped support plates.

[0008] Furthermore, the alignment ring is provided with multiple limit slots, which are evenly distributed around the circumference of the alignment ring axis; the number of limit slots is equal to the number of contact blocks and their positions correspond, and each contact block is interference-fitted into the corresponding limit slot.

[0009] Furthermore, the contact block includes: a locking part for interference fit in the limiting slot; and a contact part connected to the locking part.

[0010] Furthermore, the support component includes: a connecting block, which is fixedly connected to the alignment ring; and a support base, which is fixedly connected to the connecting block.

[0011] Furthermore, the support also includes a connecting seat, which is disposed on the support body and is used to connect with an external adjustable bracket.

[0012] Furthermore, the rotating assembly includes: a drive shaft rotatably mounted on a support base; a driven gear fixedly sleeved outside the drive shaft; a drive motor mounted on the support base, with a driving gear sleeved outside the output end of the drive motor; and a driving gear used to drive the driven gear to rotate; wherein, a fixed bracket is fixedly sleeved outside the drive shaft, and the driven gear meshes with the driving gear.

[0013] A millimeter-wave therapy device includes the aforementioned irradiation head assembly.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows.

[0015] 1. Compared with the traditional method of directly aiming the treatment device at the patient's treatment area, the present invention can avoid visual interference caused by the head of the treatment device covering the patient's eyes, thereby achieving more accurate and convenient positioning.

[0016] 2. When the patient has trauma in the treatment area, the trauma can be avoided by adjusting the position of the alignment ring or by removing the contact block; at the same time, it is convenient to lay sterile gauze on the support component to cover the trauma and avoid secondary damage to the patient's trauma site; at the same time, it avoids discomfort to the trauma site caused by sterile gauze during the treatment process.

[0017] 3. The support components can be used at different positions on the alignment ring, and the use of the support components as needed improves the adaptability of the entire irradiation head assembly. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] Please see Figures 1-9The present invention provides a technical solution: an irradiation head assembly, comprising a support member 1 and a fixing frame 2, wherein a treatment head 3 is fixed on the fixing frame 2, and the treatment head 3 is used to connect to an external host device via a connecting cable; an alignment ring 5 is provided on the support member 1, and the alignment ring 5 is used to correspond to the part of the patient to be treated; a rotating component 4 is also provided on the support member 1, the rotating component 4 is connected to the fixing frame 2, and the rotating component 4 is used to drive the fixing frame 2 to rotate or reset, thereby driving the treatment head 3 to rotate and making the treatment head 3 correspond to the position of the alignment ring 5; the support member 1 is used to connect to an external adjustable bracket (e.g., a universal adjustable bracket), thereby realizing the position adjustment and fixation of the alignment ring 5.

[0033] The rotating assembly 4 includes a drive shaft 41 rotatably mounted on the support 1, with the axis of the drive shaft 41 parallel to the axis of the alignment ring 5. The drive shaft 41 is movably mounted on the support 1 via bearings. The fixing frame 2 is fixedly sleeved on the outside of the drive shaft 41, and a driven gear 42 is also fixedly sleeved on the outside of the drive shaft 41. A drive motor 43 is mounted on the support 1, and a driving gear 44 is fixedly sleeved on the outside of the output shaft of the drive motor 43. The driving gear 44 meshes with the driven gear 42. The transmission ratio between the driving gear 44 and the driven gear 42 is greater than 1, and the drive motor 43 can be a stepper motor for convenient and precise control of the rotation angle. By driving the driving gear 44 to rotate through the drive motor 43, the driven gear 42 and the drive shaft 41 are further rotated, thereby driving the fixing frame 2 and the treatment head 3 to rotate, thus enabling the treatment head 3 to align with the alignment ring 5. Figure 7 The state shown.

[0034] The alignment ring 5 has a circular structure, and multiple contact blocks 6 are evenly distributed on the alignment ring 5. The multiple contact blocks 6 are evenly distributed around the circumference of the alignment ring 5 axis, and each contact block 6 can be detachably mounted on the alignment ring 5. Specifically, the alignment ring 5 is provided with multiple limiting slots 51, the number of limiting slots 51 being equal to the number of contact blocks 6, and each contact block 6 is respectively fitted into a limiting slot 51. The contact block 6 consists of a contact part 61 and a locking part 62. The contact part 61 and the locking part 62 can be integrally molded. The entire contact block 6 can be made of rubber or silicone to give it a certain degree of elasticity. In addition, the locking part 62 is used to interfere with the limiting slot 51. The cooperation between the locking part 62 and the limiting slot 51 facilitates the assembly and disassembly of the contact block 6.

[0035] In addition, when the treatment head 3 is aligned with the alignment ring 5, there is a small gap between the contact block 6 and the treatment head 3.

[0036] The contact portion 61 is used to contact the patient's skin. The thickness of the middle portion of the contact portion 61 is greater than the thickness of the alignment ring 5. The alignment ring 5 is located at the middle position of the contact portion 61 near the end of the locking portion 62. Figure 3As shown, the part of the contact portion 61 that comes into contact with the patient's skin is configured in an arc shape; since the alignment ring 5 is located in the middle of the contact portion 61 near the end of the locking portion 62, when the contact portion 61 comes into contact with the patient's skin, the contact of the alignment ring 5 with the patient's skin can be reduced or avoided.

[0037] A support component 7 can be fitted onto the alignment ring 5. The support component 7 can be positioned at different locations on the alignment ring 5, and the sterile gauze covering the patient's wound can be placed on the support component 7. Specifically, the alignment ring 5 is provided with multiple arc-shaped grooves 52, and the number of arc-shaped grooves 52 is even. Figure 5 As shown, there are six arc-shaped grooves 52, which are evenly distributed around the circumference of the alignment ring 5. The support assembly 7 is used to fit in any two adjacent arc-shaped grooves 52. The support assembly 7 includes two arc-shaped support pieces 71, which are adapted to the arc-shaped grooves 52. The two arc-shaped support pieces 71 are used to fit in two adjacent arc-shaped grooves 52. Multiple arc-shaped rods 72 of different sizes are connected between the inner ring surfaces of the two arc-shaped grooves 52. The multiple arc-shaped rods 72 have the same diameter and are in corresponding positions. The diameter of the arc-shaped rods 72 is very small and can be set to 0.5-1mm.

[0038] When the alignment ring 5 is fitted with the support component 7, the two arc-shaped support pieces 71 contained in the support component 7 are coaxial with the alignment ring 5. Since the number of arc-shaped grooves 52 on the alignment ring 5 is even, the arc-shaped support pieces 71 can be replaced to cooperate with different arc-shaped grooves 52, thereby realizing the change of position of the support component 7.

[0039] In this embodiment, the alignment ring 5 is adjusted to be close to the patient's treatment site by the action of the external adjustable bracket, so that the middle through hole of the alignment ring 5 corresponds to the patient's treatment site; if the patient's treatment site is untraumatized, the contact part 61 of the contact block 6 can be in contact with the patient's skin; then, the fixing frame 2 and the treatment head 3 are driven to rotate by the action of the drive motor 43, so that the head of the treatment head 3 corresponds to the position of the alignment ring 5, and the patient can be treated by the treatment head 3; after the treatment is completed, the treatment head 3 is driven to reset by the action of the drive motor 43.

[0040] If the patient has a wound at the treatment site, the alignment ring 5 is adjusted to be close to the patient's treatment site by the action of the external adjustable support, so that the middle through hole of the alignment ring 5 corresponds to the patient's treatment site. The alignment ring 5 is also adjusted so that each contact block 6 avoids the wound. If one or more contact blocks 6 cannot avoid the wound, the corresponding contact block 6 can be pulled out, and then the other contact blocks 6 can be brought into contact with the patient's skin. Afterwards, depending on the degree of wound healing, it can be selected whether to place the support component 7 on the alignment ring. If the degree of healing is good, the support component 7 is not needed, that is, there is no need to use sterile gauze to cover the wound. If the degree of healing is poor, the support component 7 is placed in a suitable position, and one or two layers of sterile gauze of appropriate size are laid flat on the support component 7 (specifically on multiple arc-shaped rods 72). The sterile gauze can be cut to the appropriate size. In addition, the number of support components 7 can be increased according to the wound area. The maximum number of support components 7 is half the number of arc-shaped grooves 52, that is, as shown in the figure. Figure 6 As shown, up to three support components 7 can be placed, and the three support components 7 will not interfere with each other; finally, the fixed frame 2 and the treatment head 3 are driven to rotate by the drive motor 43, so that the head of the treatment head 3 corresponds to the position of the alignment ring 5, and the patient can be treated at this time; of course, since the thickness of the sterile gauze is small, the treatment instrument will not come into contact with the sterile gauze during the rotation of the treatment instrument after the sterile gauze is laid flat; after the treatment is completed, the treatment head 3 is driven to reset by the drive motor 43.

[0041] In this embodiment, the alignment ring 5 is first aligned with the patient's treatment area, facilitating the subsequent alignment of the treatment head 3 with the patient's treatment area. Because the alignment ring 5 has a circular structure, when aligning the alignment ring 5 with the patient's treatment area, compared to the direct alignment method of traditional treatment instruments, visual interference caused by the treatment head is avoided, resulting in more accurate and convenient alignment. Simultaneously, when the patient's treatment area has a wound, the position of the alignment ring 5 can be adjusted or the contact block 6 can be removed to avoid contact with the wound. Furthermore, by placing the support component 7 at a suitable position on the alignment ring 5 and covering the wound with sterile gauze, the direct impact of the treatment head 3 on the patient's wound area during treatment is reduced or avoided. On the other hand, direct contact between the sterile gauze and the wound is prevented, thus avoiding discomfort caused by the sterile gauze during treatment.

[0042] Since the support component 7 can be fitted at different positions on the alignment ring 5, and more than one support component 7 can be used as needed, it is easy to meet different usage requirements and improve the adaptability of the entire irradiation head assembly. When the support component 7 is not needed, it can be removed, which helps to avoid weakening the treatment effect of the treatment head 3.
