Description

Technical Field

[0001] The present invention belongs to the field of communication technology, and in particular relates to a control method, device and medium for prostate steam ablation. Background Art

[0002] Benign prostatic hyperplasia (BPH) is a common disease in middle-aged and elderly men. The lower urinary tract symptoms caused by BPH are mainly storage symptoms, voiding symptoms, post-micturition symptoms and related complications. Various symptoms may appear one after another or develop progressively throughout the course of the disease. Some patients may experience symptoms of overactive bladder (OAB), a syndrome characterized by urgency symptoms, often accompanied by frequent urination and nocturia, with or without urge incontinence.

[0003] Surgery for benign prostatic hyperplasia can be divided into invasive surgery and non-invasive surgery. Among them, invasive surgery mainly includes improved methods of resection such as transurethral prostatectomy and holmium laser prostatectomy. Transurethral prostatectomy is the standard method for surgical treatment of prostatic hyperplasia, and the requirements for the operator are relatively high. The advantages of invasive surgery are obvious symptom improvement and low reoperation rate. The disadvantages are many adverse reactions and impact on sexual function; non-invasive surgery can be called minimally invasive surgery. Minimally invasive therapy has been shown to improve urethral symptoms caused by prostatic hypertrophy, and it is less invasive and can minimize postoperative complications.

[0004] Steam ablation equipment has unique advantages, including short operation time, less trauma, and stable effect. However, the current operation of steam ablation equipment depends on the operator's experience and lacks intelligent control methods. Summary of the invention

[0025] The ablation gun information is updated.

[0026] Preferably, in the control method of prostate steam ablation, the steam ablation device is controlled to heat the sterile liquid preheated to the critical steam state to the water vapor state, so that the water vapor is output from the ablation gun to perform steam ablation treatment on the area to be treated according to the number of treatments.

[0047] In the embodiments of the present invention, the term "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0048] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0049] In the embodiments of the present invention, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0050] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, it can be understood by those skilled in the art that in the embodiments of the present invention, many technical details are proposed in order to enable the reader to better understand the present invention. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present invention can also be implemented. The division of the following embodiments is for the convenience of description and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined and referenced with each other under the premise of no contradiction.

[0051] In order to solve the above problems, this embodiment relates to a control method for prostate steam ablation, which is applied to a steam ablation device, wherein the steam ablation device includes an ablation gun.

[0052] The following is an explanation of the implementation details of the control method for prostate steam ablation according to the first embodiment of the present invention. The following content is only provided for the convenience of understanding and is not necessary for the implementation of this solution.

[0053] The specific process of this implementation is as follows: Figure 1 As shown, the control method includes:

[0054] Step S100, acquiring image information of a target area of ​​a patient to be treated and current ablation gun information;

[0055] It should be understood that the image of the target area of ​​the patient to be treated may be a color ultrasound image acquired in advance, or may be an image acquired by a camera device on the endoscope of the ablation gun, and no specific limitation is made here.

[0056] More specifically, each patient to be treated is provided with a unique identification number (such as a hospitalization number), and the hospitalization number can be used to obtain an image of the patient to be treated in the server (the image can be a color ultrasound image of the patient to be treated); or the volume size of the patient's prostate middle lobe, lateral lobe, etc. can be obtained from the server and then the corresponding prostate area can be modeled to obtain image information of the target area.

[0057] It should be noted that the target area refers to the prostate area of ​​the patient to be treated.

[0058] Step S200, determining the area to be treated and the number of treatments according to the image information;

[0059] It should be understood that determining the area to be treated through image information may be determining the abnormal area based on the image information, for example, when the volume of each part is greater than a preset threshold compared with the normal volume, the part is considered to be abnormal; it may also be determining the area to be treated and the number of treatments in response to user input instructions, for example, the operator selects the prostate treatment area and the number of treatments based on the image information (which may be displayed in the form of a graphical interface for the operator's convenience).

[0060] It should be noted that using image information as the basis for surgical treatment in real time to determine the area to be treated and the number of treatments can facilitate doctors' reference before and during surgery and prevent doctors from repeating multiple treatments in a certain area.

[0061] In specific implementation, the step S200 includes:

[0062] Step S210, determining the current volume of each part of the prostate according to the image information;

[0063] It should be understood that the prostate includes anterior lobe, middle lobe, posterior lobe, etc. For example, assuming that the volume of the left lobe of the prostate is 20 cm 3 If the volume of the left lobe of the prostate is 40cm 3 The left lobe is considered abnormal.

[0064] Step S220, determining the area to be treated and the number of treatments according to the current volume and normal volume of each part of the prostate.

[0065] It should be understood that the area to be treated and the number of treatments are determined based on the current volume and normal volume of each part of the prostate. The first threshold can be set. For example, when the current volume of the left lobe of the prostate minus the normal volume of the left lobe> the first threshold, it is considered that the left lobe of the prostate needs treatment. Alternatively, when the ratio of the current volume of each part of the prostate to the normal volume is greater than a preset ratio, the area to be treated and the number of treatments are determined. After the area to be treated is determined, the number of treatments for the area can be determined based on the size of the area.

[0066] In specific implementation, step S220 includes:

[0067] Step S221, determining the area to be treated according to the current volume and normal volume of each part of the prostate;

[0068] It should be understood that the area to be treated is determined based on the current volume and normal volume of each part of the prostate. Taking the left lobe of the prostate as an example, the difference between the current volume of the left lobe and the normal volume may be greater than the first threshold, or the ratio of the current volume of the left lobe to the normal volume may be greater than the second threshold, then the left lobe is considered to be the area to be treated. In other embodiments, the first threshold and the second threshold may be determined based on different parts of the prostate, and no specific limitation is made here. For example, for the left lobe, the first threshold is 10 cm 3 ; For the right lobe, the first threshold is 12cm 3 .

[0069] Step S222, determining the distance from the bladder neck to the verumontanum according to the image information;

[0070] Step S223, determining the number of treatments for the area to be treated according to the distance from the bladder neck to the verumontanum.

[0071] It should be understood that the area to be treated may include one or more of the left lobe, the right lobe, the posterior lobe, etc. Specifically, the number of treatments for each lobe of the area to be treated is determined based on whether the distance from the bladder neck to the verumontanum is greater than a third threshold, as shown in Table 1, which illustrates an embodiment of a treatment plan.

[0072] Table 1 Treatment frequency plan

[0073] Distance from bladder neck to verumontanum Number of treatments per lobe of the area to be treated ≤2.0cm 1-2 times 2.0cm-3.0cm 2-3 times ≥3.0cm 3-4 times

[0074] Assuming that the area to be treated includes the left lobe, the number of treatments of the left lobe can be determined according to the distance from the bladder neck to the verumontanum, for example, the number of treatments of the left lobe can be determined according to Table 1.

[0075] In addition, if the central zone hyperplasia causes the bladder neck to rise, the number of treatments for the enlarged central zone with a distance from the bladder neck to the verumontanum less than 2 cm is 1, and the number of treatments for the enlarged central zone with a distance from the bladder neck to the verumontanum greater than 2 cm is 2.

[0076] Further, the area to be treated includes the middle lobe; accordingly, after step S223, the control method includes:

[0077] Step S224, correcting the number of treatments of the middle lobe of the area to be treated according to the size of the middle lobe.

[0078] Step S300, controlling the ablation gun to perform steam ablation treatment on the area to be treated according to the number of treatments, and updating the ablation gun information;

[0079] It should be understood that the ablation gun information includes the usage of the ablation gun. Since the number of uses of each thermal therapy ablation catheter is limited, for example, the maximum number of uses of each thermal therapy ablation catheter is 15 times, updating the usage of the ablation gun after each treatment can facilitate the recording of the usage of consumables.

[0080] Step S400: When the total number of treatments of the ablation gun in the ablation gun information reaches a preset number, the treatment is stopped.

[0081] It should be understood that by determining the total number of treatments of the ablation gun in the ablation gun information, the consumables can be sterilized and reused, which may lead to uncontrollable treatment effects. The preset number of times can be set according to specific needs. In this embodiment, the preset number of times is 15 times.

[0082] Typically, after step S400, the control method further includes sending a prompt indicating that the number of ablation gun treatments has reached or exceeded the preset number of times when the number of ablation gun treatments is greater than the preset number of times.

[0083] The present invention obtains image information of the target area of ​​the patient to be treated and current ablation gun information; determines the area to be treated and the number of treatments based on the image information; controls the ablation gun to perform steam ablation treatment on the area to be treated according to the number of treatments, and updates the ablation gun information; stops the treatment when the total number of treatments of the ablation gun in the ablation gun information reaches a preset number. In this way, an intelligent control method for steam ablation can be implemented, and the treatment effect is more stable without relying on the doctor's experience.

[0084] Furthermore, in terms of intelligence, the existing technology is too dependent on the doctor's skills, while the present invention can determine the conditions of different parts (such as volume size) in real time based on image information to determine the area that needs to be treated and the number of treatments, thereby preventing repeated treatments;

[0085] Furthermore, the prior art is unable to detect the reuse of consumables, while the present invention updates the ablation gun information after each treatment. When the total number of treatments of the ablation gun in the ablation gun information reaches a preset number, the treatment is stopped in time. This can prevent the consumables from being reused after sterilization, and the treatment effect from being uncontrollable.

[0086] like Figure 2 As shown, in the second embodiment of the control method for prostate steam ablation provided by the present invention, step S300 comprises:

[0087] Step S310, controlling the steam ablation device to heat the sterile liquid preheated to a critical steam state to a water vapor state, so that the water vapor is output from the ablation gun to perform steam ablation treatment on the area to be treated according to the number of treatments;

[0088] It should be understood that the sterile liquid is directly heated from the critical steam state to the steam state by the steam ablation device, so that the heating speed is fast, the output energy is uniform and stable, and the energy application is efficient. Taking sterile water as an example of sterile liquid, sterile water will become a steam state when it reaches above 103°C, and the critical steam state can be defined at 90°C-100°C. The critical steam state can be defined as a difference of about 5° in the steam state. In other embodiments, it can also be set according to the heating power in the steam generating device. Assuming that the heating power of the steam generating device is large, the temperature of the critical steam state can be set smaller; assuming that the heating power of the steam generating device is small, the temperature of the critical steam state can be set larger. The temperature of the critical steam state can also be determined by the user according to needs, and no specific restrictions are made here.

[0089] The first preset condition may include the steam flow rate and the treatment time. Generally, the treatment time should not be too long, otherwise it may easily scald the patient. In this embodiment, the first preset condition includes: the steam flow rate is 0.42 ml / 9s, and the treatment time is 9s-15s. The treatment time may also be 10s, 11s, 12s, or 13s, and may also be determined according to different conditions.

[0090] The steam ablation device is controlled to heat the sterile liquid preheated to a critical steam state to above 103°C, and the steam flows out of the ablation gun at a flow rate of 0.42ml / 9s for treatment for 9s-15s.

[0091] It should be understood that if the flow rate of the sterile liquid is too fast, part of the sterile liquid will not be heated to the steam state in time, which will cause the steam to flow out unevenly. In this embodiment, the flow rate of the steam is controlled to be 0.42ml / 9s. The treatment time is controlled within 9s-15s to achieve the treatment effect while preventing the patient from being scalded. In other embodiments, it can also be determined according to different conditions.

[0092] Furthermore, in terms of uniformity of energy output, compared with the treatment intervals on the market without a temperature maintenance function, the present invention preheats the sterile liquid to a critical steam state, and heats the sterile liquid from the critical steam state to a steam state during treatment, so that the output energy is more uniform and stable, without the need for large-scale heating;

[0093] Furthermore, in terms of heating speed and treatment efficiency, compared with the current methods on the market that heat from low temperature to water vapor temperature, the present invention adopts heating from critical steam state to steam state (for example, heating from 100°C to 103°C), which has fast heating speed and efficient energy application;

[0094] Furthermore, in terms of pressure stability within the ablation gun, compared to current treatment interval devices on the market that have no temperature maintenance function, the present invention controls the heating of the sterile liquid to a critical steam state when receiving an instruction to stop treatment, so that the pressure in the steam needle remains stable, without backflow and backsuction of tissue residues due to unstable pressure, and the pressure within the needle tip is stable, without backflow and backsuction of tissue residues.

[0095] Step S320, updating the ablation gun information.

[0096] like Figure 3 As shown, the first embodiment of the control device for prostate steam ablation provided by the present invention comprises an acquisition unit 501, a determination unit 502, a control unit 503, and a judgment unit 504, wherein:

[0097] The acquisition unit 501 is used to acquire image information of the target area of ​​the patient to be treated and current ablation gun information;

[0098] It should be understood that the image of the target area of ​​the patient to be treated may be a color ultrasound image acquired in advance, or may be an image acquired by a camera device on the endoscope of the ablation gun, and no specific limitation is made here.

[0099] More specifically, each patient to be treated is provided with a unique identification number (such as a hospitalization number), and the hospitalization number can be used to obtain an image of the patient to be treated in the server (the image can be a color ultrasound image of the patient to be treated); or the volume size of the patient's prostate middle lobe, lateral lobe, etc. can be obtained from the server and then the corresponding prostate area can be modeled to obtain image information of the target area.

[0100] It should be noted that the target area refers to the prostate area of ​​the patient to be treated.

[0101] The determination unit 502 is used to determine the area to be treated and the number of treatments according to the image information;

[0102] It should be understood that determining the area to be treated through image information may be determining the abnormal area based on the image information, for example, when the volume of each part is greater than a preset threshold compared with the normal volume, the part is considered to be abnormal; it may also be determining the area to be treated and the number of treatments in response to user input instructions, for example, the operator selects the prostate treatment area and the number of treatments based on the image information (which may be displayed in the form of a graphical interface for the operator's convenience).

[0103] It should be noted that using image information as the basis for surgical treatment in real time to determine the area to be treated and the number of treatments can facilitate doctors' reference before and during surgery and prevent doctors from repeating multiple treatments in a certain area.

[0104] The control unit 503 is used to control the ablation gun to perform steam ablation treatment on the area to be treated according to the number of treatments, and update the ablation gun information;

[0105] It should be understood that the ablation gun information includes the usage of the ablation gun. Since the number of uses of each thermal therapy ablation catheter is limited, for example, the maximum number of uses of each thermal therapy ablation catheter is 15 times, updating the usage of the ablation gun after each treatment can facilitate the recording of the usage of consumables.

[0106] The judgment unit 504 is configured to stop the treatment when the total number of treatments of the ablation gun in the ablation gun information reaches a preset number.

[0107] It should be understood that by determining the total number of treatments of the ablation gun in the ablation gun information, the consumables can be sterilized and reused, which may lead to uncontrollable treatment effects. The preset number of times can be set according to specific needs. In this embodiment, the preset number of times is 15 times.

[0108] The present invention obtains image information of the target area of ​​the patient to be treated and current ablation gun information; determines the area to be treated and the number of treatments based on the image information; controls the ablation gun to perform steam ablation treatment on the area to be treated according to the number of treatments, and updates the ablation gun information; stops the treatment when the total number of treatments of the ablation gun in the ablation gun information reaches a preset number. In this way, an intelligent control method for steam ablation can be implemented, and the treatment effect is more stable without relying on the doctor's experience.

[0109] Furthermore, in terms of intelligence, the existing technology is too dependent on the doctor's skills, while the present invention can determine the conditions of different parts (such as volume size) in real time based on image information to determine the area that needs to be treated and the number of treatments, thereby preventing repeated treatments;

[0110] Furthermore, the prior art is unable to detect the reuse of consumables, while the present invention updates the ablation gun information after each treatment. When the total number of treatments of the ablation gun in the ablation gun information reaches a preset number, the treatment is stopped in time. This can prevent the consumables from being reused after sterilization, and the treatment effect from being uncontrollable.

[0111] In order to achieve the above object, the present invention also provides a steam ablation device, such as Figure 4As shown, the server includes at least one processor 601; and a memory 602 communicatively connected to the at least one processor 601; wherein the memory 602 stores instructions executable by the at least one processor 601, and the instructions are executed by the at least one processor 601 so that the at least one processor 601 can execute a control method for prostate steam ablation.

[0112] The memory 602 and the processor 601 are connected in a bus manner, and the bus may include any number of interconnected buses and bridges, and the bus connects various circuits of one or more processors 601 and the memory 602 together. The bus can also connect various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and are therefore not further described herein. The bus interface provides an interface between the bus and the transceiver. The transceiver can be one element or multiple elements, such as multiple receivers and transmitters, providing a unit for communicating with various other devices on a transmission medium. The data processed by the processor 601 is transmitted on a wireless medium via an antenna, and further, the antenna also receives data and transmits the data to the processor 601.

[0113] The processor 601 is responsible for managing the bus and general processing, and can also provide various functions, including timing, peripheral interfaces, voltage regulation, power management and other control functions. The memory 602 can be used to store data used by the processor 601 when performing operations.

[0114] In order to achieve the above object, the present invention provides a computer-readable storage medium storing a computer program, wherein the computer program implements the above control method for prostate steam ablation when executed by a processor.

[0115] That is, those skilled in the art can understand that all or part of the steps in the above-mentioned implementation method can be completed by instructing the relevant hardware through a program, and the program is stored in a storage medium, including several instructions to enable a device (which can be a single-chip microcomputer, chip, etc.) or a processor to execute all or part of the steps of the method described in each implementation of the present application. The aforementioned storage medium includes: U disk, mobile hard disk, read-only memory (ROM, Read-Only Memory), random access memory (RAM, Random Access Memory), disk or optical disk and other media that can store program codes.

[0116] Obviously, the embodiments described above are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, ordinary technicians in this field can make other different forms of changes or modifications without creative work, which should fall within the scope of protection of the present invention.
