[0002] In the prior art, when using ultrasound to locate the location of the lesion area in the area to be detected, or using ultrasound to promote the absorption of drugs in the lesion area, the ultrasonic generator often accidentally deviates from the area of ​​action of the ultrasonic generator, causing the area of ​​action of the ultrasonic generator to be unable to maintain alignment with the area to be detected and / or the lesion area, thereby causing a deviation between the subsequent drug administration area and the actual lesion area.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figure 1 、 Figure 2 As shown, the present invention discloses an ultrasonic introduction device, which includes a base 1. The base 1 is provided with: an ultrasonic assembly, which includes an ultrasonic unit 4 arranged near the distal end 3 of the base; a positioning assembly, which includes a first positioning member 5 arranged near the proximal end 2 of the base; wherein the ultrasonic introduction device has an idle state and a working state. When the ultrasonic introduction device switches from the idle state to the working state, an external force causes the base 1 to enter the vagina until it enters the vagina to a set depth; when the ultrasonic introduction device is in the working state, the ultrasonic unit 4 releases ultrasonic waves to a set area, and the first positioning member 5 is interference fit with the inner wall of the vagina.

[0032] The present invention provides an ultrasonic component and a positioning component on a base 1. The ultrasonic component is arranged near the distal end 3 of the base, and the positioning component includes a first positioning member 5 arranged near the proximal end 2 of the base. When the ultrasonic introduction device is switched from an idle state to a working state, the base 1 enters the vagina to a set depth under an external force, such as the force of an operator. When the ultrasonic introduction device is in the working state, the base 1 has entered the vagina to a set depth. At this time, there is an interference fit between the first positioning member 5 and the inner wall of the vagina. The force between the first positioning member 5 and the inner wall of the vagina plays a fixing and limiting role on the base 1, so that when the ultrasonic introduction device is in the working state, the base 1 will not be affected by the patient's vaginal contraction, the operator's accidental shaking, etc. Therefore, the base 1 drives the ultrasonic unit 4 to deviate, and then when the ultrasonic introduction device is in working state, the ultrasonic unit 4 can maintain the alignment of the ultrasonic unit 4 and the lesion area and / or the area to be detected, so that the ultrasonic unit 4 can detect the area to be detected and / or promote the drug absorption effect in the lesion area, thereby ensuring the effectiveness of the ultrasonic operation. At the same time, the first positioning member 5 also alleviates the problem that the base 1 drives the ultrasonic component to deviate due to the large vibration generated when the ultrasonic unit 4 releases ultrasonic waves, and cannot maintain the alignment of the ultrasonic unit 4 and the area to be detected and / or the lesion area, further improving the detection effect of the ultrasonic unit 4 on the area to be detected, and / or promoting the drug absorption effect in the lesion area.

[0033] The working state in this article can be understood as the state when the structure is used, and the idle state can be understood as the state when the structure is not used; for example, the working state of the ultrasonic component means that the ultrasonic component enters the vagina and generates ultrasonic waves to the lesion area or the area to be detected; the working state of the base 1 means that the base 1 has entered the vagina to the required depth; the working state of the first positioning member 5 means that the first positioning member 5 is in contact with the vagina, which can prevent the base 1 and other structures provided on the base 1 from shifting. The alignment of the ultrasonic unit and the area to be detected and / or the lesion area can be specifically achieved through other imaging devices, such as a camera inserted into the vagina. The camera can be independently set relative to the ultrasonic introduction device, or it can be set on the base 1 and connected to an external display device. The operator can adjust the direction of the ultrasonic unit by rotating the base 1 through the state between the ultrasonic unit and the area to be detected and / or the lesion area fed back by the display device.

[0034] The base 1 can be understood as having sufficient hardness to support and carry the structure of components such as the ultrasonic component, positioning component, disinfection component and drug delivery component. At the same time, the hardness of the base 1 should not be too large to avoid the base 1 accidentally touching the vaginal wall when entering the vagina, causing serious damage to the vaginal wall, and the base 1 will not be deformed due to the squeezing that the vagina may cause on it when entering the vagina. The distal end 3 of the substrate refers to the area where the substrate 1 extends into the vagina when the ultrasonic introduction device is used. The proximal end 2 of the substrate refers to the area where the substrate 1 is located outside the body and is operated by an operator or mechanical device when the ultrasonic introduction device is used. The proximal end 2 and distal end of the substrate do not refer solely to the two ends of the substrate 1. When required by the working conditions, the proximal end 2 and distal end of the substrate may also include a larger area. For example, if the working conditions require, such as if the space at the distal end 3 of the substrate is insufficient to install the ultrasonic component, drug delivery component, and disinfection component, some structures of the ultrasonic component, drug delivery component, and disinfection component are placed near the distal end of the substrate 1, in the area between the distal end and the proximal end of the substrate 1. In this case, for ease of description, the area occupied by the ultrasonic component, drug delivery component, and disinfection component is referred to as the "distal end of the substrate 1." The length of the substrate 1 is greater than the length required for the substrate 1 to enter the vagina, so that the operator or mechanical device can adjust the position and posture of the substrate 1 through the proximal end 2 of the substrate, which is the area outside the body of the substrate 1.

[0035] In the present invention, the base 1 can be a cylindrical, rectangular, or other shaped structure. Since the corners of the cylindrical structure change smoothly and do not have sharp corners, it is less likely to cause significant damage to the vagina. Therefore, a cylindrical base 1 is generally selected. If a rectangular structure is selected as the base 1, a flexible layer must be wrapped around the corners of the rectangular structure to prevent the sharp corners from directly contacting the vagina and causing serious damage to the vagina. However, regardless of the shape of the base 1, it is necessary to ensure that the base 1 and the disinfection component, ultrasonic component, positioning component, drug delivery component, etc. provided on the base 1 can smoothly enter the vagina and will not cause significant damage to the vaginal wall during the entry process.

[0036] The ultrasonic unit 4 is disposed near the distal end 3 of the substrate. This does not necessarily mean that the ultrasonic unit 4 is disposed at the distal end 3 of the substrate. Rather, it means that the ultrasonic unit 4 is closer to the distal end 3 of the substrate than the proximal end 2 of the substrate. If required by the working conditions, the ultrasonic unit 4 can be disposed at the distal end 3 of the substrate, or between the distal end 3 and the proximal end of the substrate. The ultrasonic assembly also includes an ultrasonic device connected to the ultrasonic unit 4, which is located outside the body and can generate ultrasonic waves. When the ultrasonic unit 4 is used to detect the location of the lesion, the ultrasonic unit 4 can specifically be a probe that can release ultrasonic waves, such as the ultrasonic imaging probe described in patent document CN113080869B. When the ultrasonic unit 4 is used to promote the absorption of drugs by tissue cells, the ultrasonic unit 4 can specifically be the ultrasonic probe described in patent document CN209137791U, or the ultrasonic probe described in patent document CN221412022U. The ultrasonic device can specifically be an ultrasonic diagnostic instrument, or an ultrasonic diagnostic system (commonly known as a black and white ultrasound) excluding the ultrasonic probe. It should be noted that the above-mentioned specific types of ultrasonic units 4 and ultrasonic devices are only some embodiments listed for the purpose of understanding the functions of the ultrasonic unit 4 and the ultrasonic device. The ultrasonic unit 4 can also be other probes that can release ultrasonic waves, perform ultrasonic detection, or use ultrasonic waves to promote drug absorption. Similarly, the ultrasonic device can also be other structures that can generate and output ultrasonic waves through ultrasonic components.

[0037] The ultrasonic assembly includes several ultrasonic units 4 arranged at intervals along the side of the base 1. By setting up several ultrasonic units 4, on the one hand, the coverage range of the ultrasonic wave is increased, so that the lesion area or the area to be detected can evenly receive the ultrasonic wave. On the other hand, when the total output power of the ultrasonic unit 4 is the same, compared with a single ultrasonic unit 4, setting up multiple ultrasonic units 4 reduces the output energy of a single ultrasonic unit 4, and reduces the stimulation of the ultrasonic unit 4 to the inner wall of the vagina, so as to prevent the patient from having a violent physiological reaction and pushing the ultrasonic introduction device out of the vagina, thereby reducing the working efficiency of the ultrasonic introduction device. Several ultrasonic units 4 are set at intervals, which avoids the problem of multiple ultrasonic units 4 being set up in a concentrated manner, causing the patient to be overly stimulated. However, it should be noted that the present invention sets up several ultrasonic units 4, not to reduce patient stimulation at the expense of the effect of ultrasonic detection and drug diffusion, but to reduce patient stimulation while ensuring that the ultrasonic wave can comprehensively detect the area to be detected, or promote the smooth realization of functions such as drug absorption in the lesion area. Several ultrasonic units 4 can be arranged at intervals along the extension direction of the substrate 1, or several ultrasonic units 4 can be arranged at intervals along the circumference of the substrate 1, or several ultrasonic units 4 can be distributed in a spiral shape with the axial direction of the substrate 1 as the axis; or the ultrasonic units 4 can be distributed on the substrate 1 in other directions and in other forms.

[0038] The ultrasonic unit 4 can be arranged to protrude from the outer surface of the base 1, or a groove can be provided on the base 1 and the ultrasonic unit 4 can be installed in the groove so that the ultrasonic unit 4 does not protrude from the outer surface of the base 1; the specific arrangement method depends on the working conditions.

[0039] The base 1 is provided with a channel 12 for the ultrasonic unit 4 to enter and exit the base 1. The ultrasonic assembly also includes a driving unit connected to the ultrasonic unit 4. When the ultrasonic unit 4 is in a working state, the driving unit applies a first force to the ultrasonic unit 4. The first force causes the ultrasonic unit 4 to extend out of the channel 12 until the ultrasonic unit 4 abuts the vagina. This avoids the problem of ultrasonic wave reflection and energy loss during propagation due to the gap between the ultrasonic unit 4 and the vagina, improves the efficiency of ultrasonic wave propagation in the corresponding area of ​​the vagina, enables ultrasonic wave to act on deeper tissue cells, improves the ultrasonic detection effect and promotes the absorption of drugs by tissue cells; when the ultrasonic unit 4 is in an idle state, the driving unit applies a second force to the ultrasonic unit 4, which is the opposite of the first force. The second force causes the ultrasonic unit 4 to be retracted into the channel 12 and does not protrude from the outer surface of the base 1. On the one hand, this reduces the stimulation of the ultrasonic unit 4 to the vagina, and on the other hand, it reduces the probability of the ultrasonic unit 4 being covered by the drug in the vagina and blocking the output window of the ultrasonic unit 4. In addition, a sealing member 14 such as a sealing ring can be set between the channel 12 and the ultrasonic unit 4 to fill the gap between the channel 12 and the ultrasonic unit 4, thereby preventing drugs, body fluids and other substances in the vagina from entering through the channel 12 and contaminating the output window of the ultrasonic unit 4 as much as possible.

[0040] When the channel 12 is arranged at the distal end 3 of the base, along the axial direction of the base 1, or inclined relative to the axial direction of the base 1 (excluding the radial direction of the base 1), the driving unit may include a driving rod, the first end of the driving rod extends out of the proximal end 2 of the base, and the second end of the driving rod is provided with a plurality of ultrasonic units 4. When the ultrasonic unit 4 is required to extend out of the base 1 and abut against the vagina, the operator or mechanical equipment can manipulate the second end of the driving rod to move the driving rod toward the distal end of the base 1, and then extend the ultrasonic unit 4 out of the channel 12 and abut against the vagina; when the ultrasonic unit 4 is not needed, the driving rod can be moved into the base 1 so that the ultrasonic unit 4 is retracted into the channel 12. At this time, the channel 12 includes a movement path of the ultrasonic unit 4 provided on the base 1 and in the base 1; and when the ultrasonic unit 4 is not in use, the driving rod can be pulled out of the base 1 so that the ultrasonic unit 4 is detached from the base 1.

[0041] The drive unit may also not adopt the above structure. For example, when the channel 12 includes a first channel arranged radially along the base 1, the drive unit includes a first drive rod 8 and a second drive rod 9. The first drive rod 8 is arranged along the axial direction of the base 1, and the first end of the first drive rod 8 extends out of the proximal end 2 of the base. The second end of the first drive rod 8 is provided with a first bevel gear 10. The second drive rod 9 is arranged radially along the base 1. The first end of the second drive rod 9 is threadedly connected to a support 13. The ultrasonic unit 4 is provided on the support 13. The support 13 is slidably connected to the first channel in the extension direction of the first channel. The second end of the second drive rod 9 is provided with a second bevel gear 11. The first bevel gear 10 and the second bevel gear 11 At this time, the operator can rotate the operating end to drive the second drive rod 9 to rotate via the first drive rod 8, and the second drive rod 9 to rotate the support 13. However, since the support 13 and the first channel are slidably connected in the direction of the first channel, this restricts the rotation of the support 13, so that the support 13 and the ultrasonic unit 4 can only move along the direction of the first channel under the drive of the second drive rod 9. By changing the rotation direction of the operating end, the ultrasonic unit 4 can be moved toward or away from the base 1. At the same time, the operating end can also be connected to a rotary drive device such as a rotary motor, which can drive the first drive rod 8 to rotate, saving the operator's physical strength. The number of second drive rods 9 and ultrasonic units 4 depends on the number of gears that can mesh with the first bevel gear 10. For example, if the first bevel gear 10 can mesh with two second bevel gears 11, two ultrasonic units 4 can be provided, and multiple sets of the first drive rods 8 and second drive rods 9 described above can be arranged radially along the base 1 to ensure that the number of ultrasonic units 4 meets the working conditions. Moreover, when the first driving rod 8 is arranged axially along the base 1, a second channel can also be arranged at the distal end 3 of the base along the axial direction of the base 1. At this time, the driving unit also includes a third driving rod, and the first end of the third driving rod is provided with a support 13, and the support 13 is provided with an ultrasonic unit 4. The second end of the third driving rod is provided with a third bevel gear, and the third bevel gear is engaged with the first bevel gear 10. In this way, when the first driving rod 8 is rotated, the second driving rod 9 and the ultrasonic unit 4 on the third driving rod can move in the direction of approaching and away from the base 1, thereby allowing the base 1 to release ultrasonic waves to the lesion area or the area to be detected in multiple directions at the side and distal end.

[0042] Alternatively, the channel 12 is arranged along the radial direction of the base 1 or in another direction inclined relative to the axial direction of the base 1. The driving unit includes an operating rod, the first end of which extends out of the base 1. The second end of the operating rod is provided with a plurality of support rods. The ultrasonic unit 4 is provided at the end of the support rod away from the operating rod. The support rods are elastic rods. Because the support rods are elastic rods, they can bend relative to the operating rod, thereby dividing the force of the operating rod along the axial direction of the base 1 into a force along the extension direction of the channel 12. In turn, the ultrasonic unit 4 can move along the extension direction of the channel 12, so that the ultrasonic unit 4 abuts against the vagina or retracts into the channel 12.

[0043] It should be noted that the channel 12 of the present invention can extend in the axial or radial direction of the base 1, or can be arranged at an angle relative to the axial direction of the base 1, depending on the specific working conditions. Furthermore, the drive unit is not limited to the above configuration; other structures can also be used as the drive unit while meeting the above functions.

[0044] Furthermore, a cover plate can be provided at the channel 12 to block the channel 12 and prevent drugs in the vagina from entering the channel 12 and covering the output window of the ultrasonic unit 4. For example, one side of the cover plate can be hinged to the outlet of the channel 12, and an elastic member such as a spring can be provided on the side opposite to the hinge point of the cover plate and the channel 12, with both ends of the elastic member connected to the outlet and the cover plate respectively (when the channel 12 includes a first channel and a second channel, a cover plate is provided at the outlet of the first channel and the second channel, and the setting manner of the cover plate at the outlet of the first channel and the outlet of the second channel is the same as the setting manner of the cover plate at the outlet of the channel 12). In this way, when the ultrasonic unit 4 does not extend out of the channel 12, the cover plate is buckled at the outlet under the second force applied by the elastic member, thereby avoiding the problem of vaginal drugs entering the channel 12 and covering the output window of the ultrasonic unit 4. When the ultrasonic unit 4 needs to extend out of the channel 12 and release ultrasonic waves, the driving unit applies a first force to the ultrasonic unit 4. At this time, the first force needs to be greater than the second force, so that the ultrasonic unit 4 can push the cover plate open and extend out of the channel 12 to abut against the vagina. In addition, an ejector rod can be provided, which is connected to the output end of the drive unit. The ultrasonic unit 4 is arranged along the circumference of the ejector rod and is arranged to avoid the cover plate, thereby reducing the area of ​​the ultrasonic unit 4 pushing the cover plate and the area of ​​the ultrasonic unit 4 blocked by the cover plate, so that the ultrasonic unit 4 has a sufficiently large output window.

[0045] The first positioning member 5 in the present invention has a variety of settings in terms of location, shape, and number. Specifically, only one first positioning member 5 can be provided. For example, the first positioning member 5 can be provided near the proximal end of the base 1. When the base 1 enters the vagina to a set depth, the first positioning member 5 abuts against the vaginal opening or the inner wall of the vagina near the vaginal opening, which reduces the manufacturing cost of the positioning assembly. Alternatively, the first positioning member 5 can also be provided along the distal end 3 of the base toward the proximal end of the base 1, that is, a plurality of first positioning members 5 are provided at intervals along the extension direction of the base 1. The plurality of first positioning members 5 improve the stability of the base 1 and the structure provided on the base 1 after entering the vagina, reduce the displacement of the base 1 and the structure provided on the base 1, and the interval setting avoids the problem that a large number of first positioning members 5 come into contact with the vagina, resulting in greater stimulation of the sensitive area of ​​the vagina, physiological reactions of the patient, and the vagina pushing the ultrasonic introduction device out, thereby ensuring the working efficiency of the ultrasonic introduction device.

[0046] The first positioning member 5 has two types: hard and flexible. Details can be found in the following discussion. When the first positioning member 5 is a hard first positioning member, the size of the first positioning member 5 needs to be customized according to the aperture of the patient's vagina. The first positioning member 5 can be a protrusion integrally formed with the base 1 and protruding outward relative to other areas of the base 1. Through the abutment between the protrusion and the vagina, the base 1 and structures such as the ultrasonic component provided on the base 1 can be avoided as much as possible from accidental displacement. At this time, the protrusion is a hard structure, and the first positioning member 5 is a hard first positioning member, which cannot change its shape; and / or, the first positioning member 5 can also be a balloon fixed to the outside of the base 1 by welding, bonding, etc. At this time, the first positioning member 5 is a flexible first positioning member, and the balloon can be an annular balloon or a spiral balloon arranged outside the base 1, or a plurality of point-shaped or block-shaped balloons can be arranged at intervals on the side of the base 1, including a balloon connected to a medium filling mechanism through a medium cavity provided on the base 1, and the medium filling mechanism is located outside the body. According to the type of filling medium, the medium filling mechanism can be divided into a gas-filled device such as an air pump and a liquid-filled device such as a liquid pump. The balloon has an active state and an idle state. When the balloon is in the active state, the medium filling mechanism fills the balloon with medium, causing the balloon to contact the vagina. When the balloon is in the idle state, the medium filling mechanism discharges the medium from the balloon, creating a gap between the balloon and the vagina, reducing contact between the two. It should be noted that the balloon and the protrusions should not protrude too much from the outer surface of the base 1 to prevent the first positioning member 5 from causing strong irritation to the vagina.

[0047] Furthermore, the ultrasonic introduction device in the present invention also includes a drug delivery component, which is arranged near the distal end 3 of the base body. The drug delivery component, the ultrasonic component, and the positioning component are arranged to avoid each other. When the drug delivery component is in working state, the drug delivery component can release the drug to the diseased area of ​​the vagina.

[0048] Depending on the different ways of adding drugs, the drug delivery component has various settings. For example, if the drug is applied on the base 1, it enters the vagina through the base 1 and brings the drug to the desired area. At this time, the drug delivery component can specifically be a drug delivery area provided on the base 1, that is, an area provided on the base 1 for applying the drug; or, the drug delivery area can also be a drug delivery groove provided on the base 1, and the drug delivery groove has an opening provided on the side away from the base 1. After the drug is placed in the drug delivery groove, the opening is kept facing upward to prevent the drug from falling out. After the drug delivery groove enters the vagina to a set depth with the base 1 and reaches the corresponding lesion area, the base 1 is rotated so that the drug in the drug delivery groove can be poured into the lesion area, thereby completing the drug delivery.

[0049] Furthermore, the drug delivery component may not adopt the above-mentioned structure. The drug delivery component includes a drug delivery layer that is sleeved on the outside of the base 1, and a drug storage cavity is formed between the drug delivery layer and the base 1. Alternatively, the drug storage cavity may be provided in the drug delivery layer, and a plurality of drug delivery holes 6 that are connected to the drug storage cavity are provided on the drug delivery layer. The drug delivery holes 6 are provided toward the vagina, and the longitudinal section of the drug delivery holes 6 gradually increases from the side close to the base 1 toward the side away from the base 1; wherein, the drug delivery cavity is connected to the drug delivery mechanism, and / or an elastic member is provided between the drug delivery layer and the base 1, and / or the drug delivery layer is an elastic drug delivery layer. The drug storage cavity can be specifically understood as a channel 12 connecting the drug delivery mechanism and the drug delivery hole 6. The longitudinal section of the drug delivery hole 6 gradually increases from the side close to the base 1 toward the side away from the base 1, which makes the aperture of the drug delivery hole 6 on the side close to the vagina larger and less likely to be blocked by drugs or other substances in the vagina. The drug can be continuously pumped into the drug storage cavity through a drug delivery mechanism such as a pump, so that the drug is released to the lesion area from the drug delivery hole 6, and / or, an elastic member such as a spring can be arranged between the drug delivery layer and the base 1, and the vaginal wall squeezes the drug delivery layer. When the squeeze of the vaginal wall on the drug delivery layer is greater than the force of the elastic member on the drug delivery layer toward the vaginal wall, the drug delivery layer moves toward the base 1, and the drug in the drug storage cavity is squeezed out from the drug delivery hole 6; and / or, the drug delivery layer is an elastic drug delivery layer, and the vaginal wall squeezes the drug delivery layer, so that the drug delivery layer moves toward the base 1, and the drug in the drug storage cavity is squeezed out from the drug delivery hole 6; the elastic drug delivery layer can specifically be a drug delivery layer made of silicone.

[0050] The administration holes 6 can be arranged along the circumference or the axial direction of the base 1, and / or the administration holes 6 are arranged in a spiral along the axial direction of the base 1, and / or the administration holes 6 can also be arranged along other directions of the base 1 in other distribution states. Furthermore, the administration holes 6 in the present application include a first administration hole and a second administration hole, both of which are connected to the medicine storage cavity, and the aperture of the first administration hole is smaller than that of the second administration hole. The medicine released from the first administration hole has a higher speed and can be dispersed to the cells in the deeper tissues, and the medicine released from the second administration hole has a lower speed, so that the medicine can be fully diffused around the circumference of the base 1. In short, through the cooperation of the first administration hole and the second administration hole, the medicine can be uniformly dispersed to the cells near and far, and the administration effect is improved.

[0051] Alternatively, the first administration hole and the second administration hole can also be separately administered as needed, at this time, the medicine storage cavity includes a first medicine storage cavity and a second medicine storage cavity, the administration mechanism includes a first administration mechanism and a second administration mechanism, the first medicine storage cavity is connected to the first administration hole and the first administration mechanism, and the second medicine storage cavity is connected to the second administration hole and the second administration mechanism, and the separate administration of the first administration hole and the second administration hole can be realized by operating the first administration mechanism and the second administration mechanism. The first administration mechanism and the second administration mechanism can be specifically a pump capable of delivering medicine.

[0052] Moreover, the ultrasonic introduction device in the application further comprises a disinfection assembly, the disinfection assembly and the ultrasonic assembly are arranged away from each other, the disinfection assembly comprises a plurality of medical lamps 7 arranged on the base body 1, the medical lamps 7 can be arranged along the circumference or the axis of the base body 1, and / or, can also be arranged in a spiral shape along the axis of the base body 1, and / or, can also be arranged along other directions in other distribution modes, such as arranging the medical lamps 7 at the distal end of the base body 1. The medical lamps 7 can be selected according to requirements, and can emit red light, infrared light, ultraviolet light, blue light, yellow light and the like, such as a blue light lamp capable of emitting blue light, which can kill hidden bacteria and promote tissue regeneration and healing by using the ability of blue light; or an infrared lamp capable of emitting infrared light, which can promote local blood circulation, promote cell metabolism and eliminate inflammation by using the photothermal effect of infrared light. The medical lamps 7 can be infrared physiotherapy lamps, light chips (the light chip can be understood as a lamp with small volume, which can smoothly extend into the lesion such as the vagina, and the light chip can release red light or blue light, which can have the effect of anti-inflammatory or repairing on cells) and the like, and the specific type and distribution mode of the medical lamps 7 are determined according to the working condition requirements. Moreover, a plurality of medical lamps 7 of different types can be arranged on the base body 1, such as an infrared lamp capable of emitting infrared light and a blue light lamp capable of emitting blue light. No matter what type of light the medical lamps 7 can emit, or what distribution mode the medical lamps 7 are arranged in on the base body 1, the medical lamps 7 need to meet the following conditions: when the tissue cells can be treated by using the photochemical effect (the photochemical effect can be understood as the effect of causing the tissue cells to have a photochemical reaction by light irradiation, and the photochemical effect specifically shows that the light released by the medical lamps has the effect of sterilization and anti-inflammatory, or promoting metabolism, or promoting tissue regeneration and wound healing), the volume of the medical lamps 7 needs to be small enough to smoothly extend into the lesion such as the vagina, and the heat released by the medical lamps 7 needs to be not too much to prevent the problem of losing tissue cells due to excessive heat release.

[0053] The present invention provides an anti-stick coating on the medical lamp 7 to prevent intravaginal medication or body fluids from adhering to and obstructing the medical lamp 7. Furthermore, / or, the medical lamp 7 is tapered, so that even if medication or body fluids fall onto the medical lamp 7, they will slide down the inclined surface of the medical lamp 7, thereby reducing or even preventing medication or body fluids from covering the medical lamp 7. Furthermore, / or, the ultrasonic infusion device further includes a purge hole disposed toward the medical lamp 7, the purge hole being disposed toward the medical lamp 7 and connected to a purge mechanism capable of delivering a purge medium to the purge hole. The purge mechanism can be specifically a device capable of delivering a gaseous or liquid medium to the purge hole, such as a pump. Before the medical lamp 7 disinfects tissue, the purge mechanism can be activated, and the purge medium ejected from the purge hole purges the medical lamp 7, removing any body fluids or other substances that may be covering the surface of the medical lamp 7. In addition, a camera facing the medical lamp 7 can be set on the base 1, and the camera is connected to a display device such as a computer outside the body. The operator can regularly start the sweeping mechanism by observing the image of the medical lamp 7 fed back by the display device.

[0054] When the ultrasonic introduction device in the present invention includes an ultrasonic component, a positioning component, a drug delivery component and a disinfection component, one of the working processes is: placing the drug into the drug storage cavity or the drug delivery area or the drug delivery groove, then extending the base 1 into the vagina to a set depth, and then fixing the position of the base 1 by the abutment between the first positioning member 5 and the vagina to prevent the base 1 from shifting during subsequent work. After that, turning on the medical light 7, and disinfecting the lesion area by the medical light 7. Then, the drug delivery mechanism releases the drug through the drug delivery hole 6 or the vaginal wall squeezes the drug delivery layer, so that the drug delivery hole 6 releases the drug. Then, turning on the ultrasonic unit 4, and releasing ultrasonic waves to the area where the drug is released, and promoting the absorption of the drug by tissue cells by ultrasonic waves.

[0055] The depth of the base 1 inserted into the vagina can be determined by measuring scale lines arranged along the extension direction of the base 1. The ultrasonic unit 4, medical light 7, and drug delivery port 6 can all be positioned toward the area to be detected or the lesion area, or some of the structures can be positioned toward the area to be detected or the lesion area. When other structures need to be directed toward the area to be detected or the lesion area, the angles of the other structures can be adjusted by rotating the base 1.

[0056] In the present invention, the ultrasonic component, positioning component, drug delivery component and disinfection component are arranged to avoid each other to ensure that the functions of each structure can be smoothly realized. For example, the disinfection component and the ultrasonic component are arranged to avoid the drug delivery component, which means that there is a certain distance between the disinfection component and the drug delivery component, so that the medicine released by the drug delivery component will not directly cover the ultrasonic window or the disinfection component, ensuring that the ultrasonic wave release of the ultrasonic unit 4 and the disinfection of the disinfection component can be smoothly realized.

[0057] In the present invention, the structures that are in direct contact with the vagina, such as the base 1, ultrasonic component, positioning component, drug delivery component and disinfection component, are all provided with a flexible layer to prevent accidental contact with the vagina and cause serious damage to the vagina. The flexible layer can also be made of a biocompatible flexible material, such as silicone.

[0058] The structures such as the base 1, ultrasonic component, positioning component, drug delivery component and disinfection component in the present invention are arranged to avoid the sensitive areas of the vagina as much as possible. This can be achieved by adjusting the location of the positioning component on the base 1, as well as the sizes of the base 1, ultrasonic component, positioning component, drug delivery component and disinfection component. The avoidance setting in this sentence can be understood as that when the structures such as the base 1, ultrasonic component, positioning component, drug delivery component and disinfection component enter the vagina, the vagina has less contact with the above structures, thereby reducing the stimulation of the above structures to the sensitive areas of the vagina, and to a certain extent avoiding the problem that the patient has a strong physiological reaction due to the large contact area and high contact frequency with the vagina during the process of the above structures entering the vagina, and forcibly pushing the above structures out of the vagina, thereby facilitating the effective operation of the ultrasonic introduction device.

The ultrasonic introduction device of the present invention is not limited to the attached Figure 1 and attached Figure 2 The structure in Figure 1 The proximal end 2 of the substrate is bent relative to the distal end 3 of the substrate, but the proximal end 2 of the substrate can also be coaxially arranged with the distal end 3 of the substrate as needed and located on the same axis; some structures are not fully shown in the attached Figure 1 and attached Figure 2 For details on the specific structure setting method, please refer to the above text.

[0060] The term "and / or" used herein means that the text preceding and / or and the text following and / or can exist simultaneously or independently within the same sentence. For example, "A and / or B" includes the presence of either A or B, as well as the presence of both A and B. "And / or" has the same meaning as "and / or" and is not further elaborated here.
