Description

Technical Field

[0001] The present invention relates to the technical field of ophthalmic surgery, and in particular to a temperature monitoring system and a control method thereof for ophthalmic surgery. Background Art

[0002] Cataract phacoemulsification technology is a major achievement of microsurgery. Since 1967, Dr. KELMAN from the United States invented the first phacoemulsifier and used it in clinical practice, after more than 30 years of continuous improvement and perfection by many ophthalmologists, cataract phacoemulsification technology has become a world-recognized, advanced and mature surgical method. Phacoemulsification is now popular. During the operation, the phacoemulsification probe is inserted into a small incision in the cornea or sclera of the operated eye to crush the turbid lens and cortex into chyle. The chyle is then sucked out with the help of a suction and perfusion system, while keeping the anterior chamber filled. Then an artificial lens is implanted to restore the patient's sight. Phacoemulsification technology truly realizes the ideal of small incision, no pain, short operation time, no need for hospitalization, and rapid recovery of vision.

[0003] However, during the phacoemulsification process, the ultrasonic energy not only emulsifies the lens, but also generates heat from the ultrasonic needle and the high-speed vibrating lens itself. When the heat is too high, it will have a negative impact on the human eye, causing recovery to slow down at the least and vision to deteriorate at the worst. However, there is currently no temperature monitoring device that can measure the temperature of surgical instruments or eyeball organs during ophthalmic surgery. Summary of the invention

[0059] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are 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 those skilled in the art without creative work are within the scope of protection of the present invention.

[0060] To facilitate understanding of this embodiment, the following is a brief introduction to the technologies involved in this application.

[0061] Phacoemulsification device: It uses high-frequency vibration of ultrasound to emulsify and suck out the lens nucleus. It has the advantages of less tissue damage, faster healing, shorter hospital stay, less postoperative astigmatism, and faster and more stable vision recovery. It has become an advanced device for cataract surgery in the world today.

[0062] It should be noted that the terms "first", "second", etc. mentioned in this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein.

[0063] After introducing the technical terms involved in this application, the application scenarios of the embodiments of this application are briefly described below.

[0064] During the phacoemulsification process, the phacoemulsifier uses the high-frequency vibration of ultrasound to emulsify and suck out the lens nucleus. However, the ultrasound energy not only emulsifies the lens, but the ultrasound needle and the high-speed vibration of the lens itself also generate heat. Excessive heat can have a negative impact on the human eye, which can slow down recovery or even cause vision loss.

[0065] Due to the large size of traditional temperature sensors, it is difficult to measure the temperature of surgical instruments or eye organs during ophthalmic surgery, resulting in the inability to monitor the intraocular temperature of the eye being examined during ophthalmic surgery, resulting in the safety of ophthalmic surgery not being guaranteed.

[0066] In order to solve the above technical problems, the present application proposes a temperature monitoring system for ophthalmic surgery to monitor the temperature of the eye to be examined during ophthalmic surgery, and control the output power of the phacoemulsification device according to the temperature data of the eye to be examined, so as to reduce the impact of the heat generated by the phacoemulsification device on the eye to be examined, thereby improving the reliability and safety of ophthalmic surgery.

[0067] Example 1

[0068] Combination Figure 1 As shown, this embodiment provides a temperature monitoring system for ophthalmic surgery, including: a phacoemulsification surgical instrument 1, a surgical microscope 2, a temperature monitoring device and a control device 3.

[0069] The temperature monitoring device includes a dichroic mirror and a temperature monitoring mechanism 24 .

[0070] The dichroic mirror 23 is disposed in the surgical microscope 2 and is used for transmitting visible light in the surgical microscope 2 and refracting infrared light.

[0071] The temperature monitoring mechanism 24 is disposed on the surgical microscope 2 and is connected to the optical path of the infrared light refracted by the dichroic mirror 23, thereby receiving the infrared light and generating temperature data;

[0072] The control device 3 is disposed on the phacoemulsification surgical instrument 1 , and a signal input end of the control device 3 is connected to the temperature monitoring mechanism 24 , for receiving temperature data from the temperature monitoring mechanism 24 and controlling the output power of the phacoemulsification surgical instrument 1 according to the temperature data.

[0073] The temperature monitoring system for ophthalmic surgery provided in the present application realizes real-time monitoring of the intraocular temperature of the eye to be inspected 6 by arranging a dichroic mirror 23 in the surgical microscope 2 to separate visible light from infrared light, and obtains temperature data by imaging after receiving the infrared light through the temperature monitoring mechanism 24. In addition, the control device 3 controls the output power of the phacoemulsification surgical instrument 1 according to the temperature data, so as to reduce heat generation when the intraocular temperature of the eye to be inspected 6 is too high, thereby reducing the adverse effects of excessive temperature on the eye to be inspected 6 during ophthalmic surgery, thereby improving the safety of ophthalmic surgery.

[0074] As an implementable approach, combining Figure 2 As shown, the surgical microscope 2 includes an imaging unit 201 , an illumination unit 202 and an electronic control unit 203 .

[0075] The imaging unit 201 is used to acquire and enlarge the image of the eye to be inspected 6 .

[0076] The illumination unit 202 is used to provide illumination for the optical path of the surgical microscope 2 .

[0077] The electronic control unit 203 is used to control the working mode of the surgical microscope 2 .

[0078] As an implementable approach, combining Figure 3 As shown, the imaging unit includes: an objective lens 21 and an eyepiece 22.

[0079] The objective lens 21 is used to obtain a real image of the eye 6 to be inspected.

[0080] The eyepiece 22 is used to magnify the image formed by the objective lens 21 , and the eyepiece 22 is coaxial with the objective lens 21 .

[0081] As an practicable manner, the dichroic mirror 23 is disposed between the eyepiece 22 and the objective lens 21 (combined with Figure 3 shown).

[0082] Under the illumination of the illumination unit 202, light enters the surgical microscope 2 from the objective lens 21. Under the action of the dichroic mirror 23, natural light and infrared light are separated. The natural light is transmitted by the dichroic mirror 23 and continues to propagate along the original optical path (the direction from the objective lens to the eyepiece). The infrared light is refracted by the dichroic mirror 23 and is received by the temperature monitoring mechanism 24 along the second optical path. The temperature monitoring mechanism 24 obtains a thermal image according to the principle of thermal imaging and obtains temperature data. In this embodiment, the light of the light source is separated into the natural light path and the infrared light path by relying on the working principle of the dichroic mirror 23, and then the temperature data is obtained according to the principle of thermal imaging.

[0083] As an implementable manner, the dichroic mirror 23 is a movable structure.

[0084] The dichroic mirror 23 can be moved up and down between the eyepiece 22 and the objective lens 21 , as long as the optical path of the infrared light reflected by the dichroic mirror 23 is connected to the temperature monitoring mechanism 24 .

[0085] As an implementable manner, a slideway is provided on the inner wall of the body of the surgical microscope 2, and the dichroic mirror 23 is slidably connected to the slideway, and the position of the dichroic mirror 23 can be changed by pushing the dichroic mirror 23. Preferably, a limiting mechanism is also included, and the specific position of the dichroic mirror 23 is limited by the limiting mechanism. The specific position can be set during the manufacturing process. This is a more common sliding connection method, which will not be described in detail here.

[0086] As an implementable method, in this embodiment, the temperature monitoring mechanism 24 is a thermal imaging sensor, which obtains the image and temperature data of the subject's eye 6 according to the collected infrared light through thermal imaging. The thermal imaging sensor is connected to the control device 3 in the phacoemulsification surgical instrument 1, so as to transmit the temperature data to the control device 3, wherein the temperature monitoring mechanism 24 and the control device 3 can be connected by wireless communication or by line. In this embodiment, in order to ensure the timeliness and reliability of data transmission, the thermal imaging sensor is combined with the control device 3 to transmit the temperature data to the control device 3. Figure 1 As shown, the temperature monitoring mechanism 24 is connected to the control device 3. The control device 3 can be arranged inside, on the side, on the top, etc. of the phacoemulsification surgical instrument 1. In this embodiment, the temperature monitoring mechanism 24 is connected to the control device 3. Figure 1 As shown, the control device 3 is arranged on the top of the ultrasonic emulsification surgical instrument 1. The control device 3 judges the temperature data. If the temperature data is greater than a preset threshold, the control device controls the ultrasonic emulsification surgical instrument 1 to reduce the output power, thereby reducing heat generation, reducing the intraocular temperature of the eye 6 to be inspected during ophthalmic surgery, thereby reducing the safety risks of the surgery and improving the safety of ophthalmic surgery.

[0087] As an implementable method, in this embodiment, the temperature monitoring mechanism 24 can also be an infrared thermal imager. The infrared sensor can detect and measure the infrared radiation emitted by the infrared light, that is, the heat signal, and convert the heat signal into temperature data and transmit it to the control device 3. The control device 3 judges the temperature data. When the temperature data is greater than a preset threshold, the ultrasonic emulsification surgical instrument 1 is controlled to reduce the output power, thereby reducing the impact of the heat generated by the ultrasonic emulsification surgical instrument 1 during the ophthalmic surgery on the eye to be inspected 6.

[0088] As an implementable manner, the phacoemulsification surgical instrument 1 includes: a surgical instrument host and a phacoemulsification handle 5 .

[0089] The phacoemulsification handle 5 is connected to the surgical instrument host through a line 4 (combined Figure 1 As shown). The phacoemulsification handle 5 is used for anterior segment surgery of cataract lens fragmentation, perfusion and aspiration, as well as vitrectomy and electrocoagulation. The phacoemulsification handle 5 mainly includes two parts: an ultrasonic transducer and an ultrasonic amplitude transformer. During actual work, a tool head will also be installed at the front end. The function of the ultrasonic transducer is to convert electrical energy into mechanical vibration, but the vibration amplitude of its radiation section is only a few microns. When the phacoemulsifier is used for cataract removal surgery, the vibration amplitude of the radiation end face generally needs to be tens to more than one hundred microns. Therefore, an ultrasonic amplitude transformer must be connected to the end face of the transducer to amplify the amplitude of the mechanical vibration. The tool head is designed for different purposes and acts directly on the load. During the ophthalmic operation, the doctor holds the phacoemulsification handle 5 and applies the tool head at the front end of the phacoemulsification handle 5 to the eye to be examined 6 (combined with Figure 1shown).

[0090] As an implementable method, the surgical instrument host includes an energy control unit 103, and the energy control unit 103 includes an ultrasonic signal generator; wherein the ultrasonic signal generator is connected to the control device 3, and is controlled by the control device 3 to increase or decrease the output power according to the temperature data to adjust the output power of the ultrasonic emulsification surgical instrument.

[0091] Combination Figure 4 As shown, the surgical instrument host further includes: a signal generator 101 , a negative pressure flow control unit 102 , an energy control unit 103 and a human-machine interaction interface 104 .

[0092] Among them, the signal generator 101, the negative pressure flow control unit 102, the energy control unit 103 and the human-machine interaction interface 104 are all connected to the control device 3 (combined with Figure 5 Specifically, the signal generator 101, the negative pressure flow control unit 102, the energy control unit 103 and the human-machine interface 104 are all connected to the control device 3, and the current working parameters are sent to the control device 3. The control device 3 controls the signal generator 101, the negative pressure flow control unit 102, the energy control unit 103 and the human-machine interface 104 to perform different operations according to the current working parameters. For example, the control device 3 receives the image and temperature data of the eye 6 to be inspected transmitted by the temperature monitoring device, and then the control device sends a display instruction to the human-machine interface 104 and sends an output power reduction instruction to the energy control unit 103. The human-machine interface 104 displays the intraocular image of the eye 6 to be inspected in response to the control instruction, and the energy control unit 103 reduces the output power of the phacoemulsification surgical instrument in response to the control instruction.

[0093] As an implementable method, the energy control unit package 103 includes an ultrasonic signal generator, which is connected to the control device and controlled by the control device 3 to increase or decrease the output power of the ultrasonic signal generator according to the temperature data. When the output power increases, the heat generated also increases, resulting in an increase in the temperature acting on the eye to be inspected 6, which may easily cause discomfort to the eye to be inspected 6. When the output power is reduced under the control of the control device 3, the heat generated decreases accordingly, and the temperature acting on the eye to be inspected 6 also decreases accordingly.

[0094] Example 2

[0095] This embodiment provides a temperature monitoring system for ophthalmic surgery, including: a phacoemulsification surgical instrument 1, a surgical microscope 2, a temperature monitoring device and a control device 3.

[0096] The temperature monitoring device is an infrared temperature sensor, which corresponds to the eye to be inspected 6 (not shown in the figure), so that the eye to be inspected 6 is located within the detection range of the temperature monitoring device, so as to obtain the temperature of the eye to be inspected 6 and generate temperature data, which is then transmitted to the control device 3. Specifically, a mounting frame can be selected, and the temperature monitoring device can be mounted on the mounting frame and fixed, and the eye to be inspected 6 can be placed within the monitoring range of the temperature monitoring device by adjusting the angle.

[0097] The control device 3 controls the working mode of the phacoemulsification surgical instrument 1 according to the temperature data, so as to monitor the temperature data of the eye 6 to be examined during the ophthalmic surgery and adjust the output power of the phacoemulsification surgical instrument 1 according to the temperature data, so as to improve the safety of the ophthalmic surgery.

[0098] Example 3

[0099] In the second aspect, an embodiment of the present application also provides a control method for an ophthalmic emulsification surgery temperature monitoring system, which is applied to a control device 3 in the above-mentioned system, and the control device 3 includes a memory and a processor, the memory is used to store computer programs, and the processor is used to execute the computer programs stored in the memory to implement the control method for an ophthalmic emulsification surgery temperature monitoring system provided in the present application.

[0100] Combination Figure 6 As shown, the method comprises the following steps:

[0101] S110, the processor obtains first temperature data inside the eye to be inspected detected by the temperature monitoring device.

[0102] S120: The processor determines whether the first temperature data is greater than a preset first threshold.

[0103] If the first temperature data is greater than the preset first threshold, step S130 is executed.

[0104] If the first temperature data is less than or equal to the preset first threshold, step S140 is executed.

[0105] S130: The processor modifies the current output power of the phacoemulsification surgical instrument to the target output power to reduce heat generation.

[0106] S140, the processor controls the phacoemulsification surgical instrument to operate at a preset output power.

[0107] In this embodiment, the image of the eye under examination 6 and the first temperature data are obtained by the temperature monitoring device and transmitted to the control device 3. The control device 3 determines the comparison relationship between the first temperature data and the first threshold value preset in the control device 3, and controls the output power of the phacoemulsification surgical instrument according to the comparison relationship to adjust the heat generated by the operation of the equipment during the ophthalmic surgery to avoid the adverse effects of excessive temperature on the eye under examination during the operation.

[0108] In combination with the second aspect, step S130 of modifying the current output power of the phacoemulsification surgical instrument to the target output power includes:

[0109] Calculate the target output power using the following formula:

[0110] P n =P n-1 -A(T n -T n-1 )-B(T n -T s );

[0111] Among them, Pn is the target output power, Pn-1 is the current output power; A is the compensation coefficient, B is the adjustment coefficient, Tn is the current temperature inside the eye under inspection; Tn-1 is the previous temperature inside the eye under inspection; Ts is the first threshold value preset in the control device.

[0112] In this embodiment, by calculating T n -T n-1 , the speed of temperature rise or fall in the eye of the subject is obtained; by calculating P n-1 -B(T n -T s ), and obtain the output power that the phacoemulsification surgical instrument should take under the current situation; in order to avoid overshoot when adjusting the output power when the temperature rises too high, that is, when the power is adjusted too quickly and the temperature drops too quickly, the output power and temperature will easily oscillate at the set power and temperature thresholds. Therefore, when calculating P n-1 -A(T n -T n-1 ) and then subtract A(T n -T n-1 ) to prevent oscillation caused by too fast output power adjustment.

[0113] Example 4

[0114] In this embodiment, the control method of the temperature monitoring system for ophthalmic emulsification surgery is applied to the control device 3 in the temperature monitoring system for ophthalmic emulsification surgery. The control device 3 is preset with multiple working modes and the output power of the phacoemulsification surgical instrument corresponding to each working mode. Figure 7 As shown, the method in this embodiment includes the following steps:

[0115] S210: The processor obtains first temperature data inside the eye to be inspected.

[0116] S220: The processor determines whether the first temperature data is greater than a preset first threshold.

[0117] If the first temperature data is greater than the first threshold, step S230 is executed.

[0118] If the first temperature data is less than or equal to the first threshold, step S260 is executed.

[0119] S230: The processor modifies the current output power of the phacoemulsification surgical instrument to the target output power to adjust the output power of the phacoemulsification surgical instrument.

[0120] S240: The processor obtains second temperature data inside the eye to be inspected.

[0121] S250: The processor determines whether the second temperature data is greater than a first threshold.

[0122] If the second temperature data is less than or equal to the first threshold, step S260 is executed.

[0123] S260: The processor controls the phacoemulsification surgical instrument to operate according to the output power corresponding to the current working mode.

[0124] In this embodiment, when the temperature in the eye 6 to be inspected is too high, the temperature during the ophthalmic surgery is reduced by adjusting the output power of the phacoemulsification surgical instrument 1, and then the second temperature data in the eye to be inspected is obtained from time to time. After that, the second temperature data is compared with the first threshold value, until the second temperature data is less than or equal to the first threshold value, indicating that the temperature during the ophthalmic surgery is already too low, at this time, the phacoemulsification surgical instrument 1 is controlled to work at the output power corresponding to the current working mode, so as to gradually increase the heat generated during the working process.
