Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a gynecological laser treatment blade with pressure visual detection and an adaptive control method. Background Art

[0002] Gynecological conditions such as vaginitis, cervical erosion, and uterine fibroids are common among women, seriously endangering their physical and mental health. Semiconductor laser therapy devices, as a new type of healthcare device with high efficacy, rapid results, no pain, wide application, and no side effects, are being adopted by an increasing number of hospitals. Semiconductor laser therapy devices have a wide range of applications in the medical and beauty fields and have been widely recognized by users.

[0003] The core component of a semiconductor laser therapy device is the laser treatment head, which treats the diseased area through laser burning. During the burning process, a certain amount of smoke will inevitably be produced, so the smoke needs to be discharged from the body. At present, the shell of the laser treatment head is disposable, and consumables are seriously wasted. In addition, although the laser treatment head has a smoke channel, smoke will still overflow from the treatment position of the diseased area and enter the inspection channel. Moreover, the smoke channel is not specific in the laser treatment head, and the smoke will be deposited and contaminate the lens combination reflector. In addition, if body fluids come into contact with the reflector, it will also affect the laser reflection effect of the reflector and affect the treatment effect of the disease. Moreover, the existing laser power and time control are all based on experience, without an accurate operating standard, and high requirements are placed on technical personnel.

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0031] like Figure 1-3 As shown, the gynecological laser treatment head with pressure visual detection includes a tube body, and the tube body has a laser lens group 10 built in. The tube body includes two sections, front and back, wherein the diameter of the front section 1 of the tube body is smaller than the diameter of the rear section 2 of the tube body, and the rear section 2 of the tube body has a main cavity 3, and the main cavity extends 3 to the front section 1 of the tube body, and the laser lens group 10 is located in the main cavity 3. The rear section 2 of the tube body also has two air cavities 4, and each air cavity 4 is connected to an trachea 41, one of which is an exhaust pipe and the other is an air return pipe. The front end side wall of the air cavity 4 is also provided with an air hole 42. The front section of the tube body is inserted into the smoke hood 5 and then fixed by a tail plug 6. The side wall of the smoke hood 5 has two air nozzles 51, and each air nozzle 51 is inserted into the corresponding air hole 42. The top of the smoke hood is open, and a reflector 7 and a camera assembly 8 are installed in the main cavity of the front section 1 of the tube body. The top of the main cavity of the front section 1 of the tube body is a transparent glass plate 21. The reflector 7 and the camera assembly 8 are opposite to the top opening of the smoke hood. A pressure sensor 9 is provided at the rear section of the tube body near the top of the smoke hood.

[0032] In this structure, the gynecological laser treatment blade is installed with the handheld part during use, and it also cooperates with the control host, air pump, laser source, etc. The principle is that the laser emitted by the laser source is adjusted through the optical path of the laser lens group, and then reflected by the reflector, penetrates the glass plate and irradiates the diseased area, and the disease is treated by laser burning. In order to ensure accuracy, the reflector is placed at an angle of 45 degrees. In addition, the camera assembly is used to capture the image of the contact position between the top opening of the smoke hood and the diseased area to perform laser control. In the figure, the camera assembly is located in front of the reflector, and the camera assembly is set toward the top opening of the smoke hood. In addition, the opening position of the top opening of the smoke hood is flat, which makes it easy to achieve a close fit between the top opening of the smoke hood and the diseased area without leaving any gaps.

[0033] The device as a whole is a detachable structure. The smoke hood and tail plug can be removed, but the tube body cannot be detached. The tube body is relatively isolated from the smoke hood and tail plug. After the smoke hood is installed on the front section of the tube body, it is fixed with the tail plug. As a method, the head end of the front section of the tube body is a threaded section, and the tail plug is screwed into the threaded section. In order to ensure sealing, the front end of the tail plug is spherical, and sealing rings are provided between the tail plug and the smoke hood, and between the smoke hood and the side wall of the rear section of the tube body.

[0034] Through this structural design, first, the two air cavities and the smoke hood form a smoke channel. In the two air pipes, air is extracted from the exhaust pipe and naturally returned to the return pipe. The gas forms a directional airflow in the smoke channel, so that the smoke generated in the diseased area by laser burning enters the smoke hood and is quickly extracted; second, since a pressure sensor is set near the smoke hood, the top opening of the smoke hood is close to the diseased area. According to the display value of the pressure sensor, it can be judged whether the smoke hood and the diseased area are closed, leaving a gap to prevent the generated smoke from overflowing from the gap into the body; third, the smoke hood is detachable. After use, the smoke hood can be disassembled and each part can be cleaned. Including a glass plate, the device can be reused after disinfection, and the smoke hood and tail plug can be directly replaced. You only need to clean the tube body. It should be noted that when cleaning the front part of the tube body, you can use a plug to block the air hole to prevent moisture from entering the air cavity; Fourth, the glass plate design can separate the smoke from entering the main cavity without affecting the laser and camera components, and an oleophobic layer is preferably provided on the glass plate, even if there is a small amount of body fluid during the inspection process, it will not gather on the glass plate; Fifth, the present invention is provided with a camera component, which can capture images of the diseased area through the glass plate, can identify the image, and perform corresponding laser power and processing time control, which has low requirements for technical personnel.

[0035] Based on the above structure, the embodiment of the present invention also provides an adaptive control method for gynecological laser treatment, such as Figure 5 As shown, the following steps are included:

[0036] Step S1: connect the gynecological laser treatment blade to the handheld part, turn on the camera assembly, and operate the gynecological laser treatment blade to enter the inspection channel through the operator.

[0037] Handheld structure Figure 4 As shown, the handheld part is connected to the gynecological laser treatment blade, and the handheld part is also connected to the laser source. The laser emitted by the laser source can enter the tube body through the handheld part, and then pass through the lens group and reflector to irradiate the diseased area.

[0038] After turning on the camera assembly, you can start operating the handheld part to push the gynecological laser treatment blade into the patient examination channel.

[0039] Step S2: With the aid of the video transmitted back by the camera assembly, after the gynecological laser treatment blade enters the treatment area, the top opening of the smoke collection hood is placed close to the treatment area until the pressure sensor reaches the set value.

[0040] Thanks to the camera assembly, this device eliminates the need for a separate endoscope. The camera assembly allows users to see the current location of the smoke hood's top opening, making it very easy to operate and reducing the technical requirements of the doctor. With the aid of the video feed from the camera assembly, the gynecological laser treatment blade can be quickly positioned at the affected area.

[0041] Because of the pressure sensor, after the gynecological laser treatment blade is pushed into the treatment area of ​​the disease, the top opening of the smoke collection hood is placed close to the treatment area. According to the data sent back by the pressure sensor, it can be judged whether the opening is close to the treatment area to avoid gaps. By setting up the pressure sensor, the technical requirements for doctors are also reduced.

[0042] Step S3: The camera assembly captures an image of the target area within the top opening of the smoke hood and transmits the image back to the control host.

[0043] Before treatment, the target area image is first captured by the camera assembly, and the control host performs recognition based on the target area image.

[0044] Step S4: The control host analyzes the target area image, determines the disease level, and obtains the laser power and processing time according to the disease level.

[0045] Laser treatment of symptoms in the target area requires confirmation of the symptom level. Not all areas require the same laser parameters. An example process for confirming the symptom level is as follows:

[0046] S41 , filtering edge pixels of a certain width around the target area image, and retaining the remaining pixel images.

[0047] Since the edge of the top opening of the smoke hood presses down the treatment target area, the edge position of the target area will be significantly different from the actual performance, such as reddish color, which will affect subsequent judgment. Therefore, these pixels need to be removed here.

[0048] S42, identifying the background pixels of the remaining pixel image, then extracting the foreground pixels, and calculating the disease proportion of the foreground pixels in the entire remaining pixel image.

[0049] In this step, the remaining pixel image after the elimination is first identified by background pixels. Background pixels are easy to identify, and there is a clear difference between the normal color and the diseased color of the inspection channel. In addition, if there are normal areas in the inspection channel, you can also obtain an image of the normal area and then use it as the background color to identify the remaining pixel image. Then, foreground pixels are identified. Foreground pixels are pixels that generate diseased areas. All pixels other than background pixels are foreground pixels, and the disease ratio is calculated. If the entire remaining pixel image is foreground pixels, then the disease ratio is close to 1.

[0050] S43. For the extracted foreground pixels, identify the disease type through a convolutional neural network model.

[0051] Convolutional neural network models have been used in disease recognition. Sample training and validation can yield models with high accuracy. These models can identify the type of disease in foreground pixels, such as vasodilation, erosion, or ulcer. Different disease types require different treatments. The more severe the disease, the longer and more intensive the treatment.

[0052] S44. Obtain the corresponding lesion grade according to the symptom ratio and symptom type.

[0053] The lesion ratio is the percentage of diseased areas within the target area. The higher the ratio, the higher the lesion grade. Furthermore, the more severe the lesion type, the higher the lesion grade. Initially, a mapping table is set to empirically determine the lesion grade, corresponding laser power, and treatment time.

[0054] Step S5, adaptively control the laser source to output a laser of corresponding power, and then pass it through the laser lens group and the reflector to the target area, and process the laser treatment target area according to the obtained processing time. During the treatment, the smoke generated by the burning is extracted from the exhaust pipe through the air pump until the current target area is processed and the smoke is completely extracted.

[0055] After determining the lesion grade, the corresponding laser power and treatment time are obtained by searching the mapping table, and the laser source can be controlled accordingly. During the laser treatment of the target area, the generated smoke is completely extracted.

[0056] Step S6: Move the gynecological laser treatment blade to the next target area and continue the operation until the treatment area is completed.

[0057] Finally, when the treatment of one target area is completed, the treatment of the next target area will be continued until the entire treatment area is treated.

[0058] In summary, the present invention has a simple structure, and the smoke hood is detachable and easy to replace; the reflector and the camera assembly are located in the closed main cavity and are not affected by the body fluids and smoke in the inspection channel; in addition, a pressure sensor is also provided at the rear section of the tube body near the smoke hood. When operating the gynecological laser treatment blade, the top opening of the smoke hood can be made close to the diseased area without any gaps, so that the smoke generated by the treatment laser will not enter the body and can basically all be extracted; in addition, the present invention is also provided with a camera assembly, which can capture the image of the diseased area through the glass plate, can identify the image, and perform corresponding laser power and processing time control, which has low requirements for technical personnel; the air cavity and the main cavity are relatively independent, and the smoke will not contaminate the components in the main cavity. The smoke hood can be removed to facilitate cleaning of various parts, including the glass plate. The device can be reused after disinfection, or the smoke hood and tail plug can be directly replaced, and only the tube body needs to be cleaned.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
