Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a device for detecting intraocular pressure changes during massage after glaucoma surgery and its usage method. Background Technology

[0002] Glaucoma is a disease caused by intermittent or persistent increases in intraocular pressure, leading to damage to the optic nerve tissue and gradually causing visual field defects and vision loss. Glaucoma is usually a chronic eye disease that progresses gradually. In the early stages, there may be no obvious symptoms, but if left untreated, it will gradually worsen. Therefore, patients need long-term, regular eye examinations, monitoring, and treatment to control intraocular pressure and protect their vision.

[0003] Although glaucoma is not an acute disease, in certain special circumstances, a sudden and dramatic increase in intraocular pressure can trigger an acute glaucoma attack. Acute glaucoma attacks are often accompanied by severe eye pain, headache, blurred vision, and halos around lights, requiring immediate medical attention.

[0004] Currently, existing treatments for glaucoma aim to reduce intraocular pressure, slow optic nerve damage, and protect vision. Treatment methods include laser-assisted trabeculoplasty (LAT), glaucoma filtration surgery (trabeculectomy), glaucoma drainage implantation surgery, and selective laser trabeculoplasty (SLT). Postoperative recovery after glaucoma filtration surgery and drainage valve implantation surgery requires long-term massage to improve aqueous humor flow and relieve intraocular pressure; this involves massaging the eyes under the guidance of a doctor.

[0005] Glaucoma filtering surgery is a common surgical method for treating glaucoma. It reduces intraocular pressure by creating a channel to control the progression of glaucoma. Postoperative scar management is an important aspect of filtering surgery because scarring during the healing process often affects the surgical outcome. Therefore, massage is even more important for postoperative recovery after glaucoma filtering surgery. It can relieve tension in the scar tissue at the surgical site, thereby promoting scar softening and diffusion, and significantly improving the speed and effectiveness of postoperative recovery.

[0006] However, since postoperative patients cannot stay in the hospital for massage therapy with the help of doctors, patients usually cannot guarantee the massage effect when they massage at home. Moreover, they cannot accurately avoid the drainage valve and filter channel to achieve simultaneous and safe massage of both sides of the eyeball. In addition, they cannot monitor changes in intraocular pressure and cannot adjust the massage method and intensity in a timely manner according to changes in intraocular pressure to evaluate the massage effect. Summary of the Invention

[0007] To address the challenges of postoperative massage after glaucoma surgery, where patients often struggle to achieve the desired effect when performing self-massage at home, it's difficult to precisely avoid drainage valves and filtration channels, and real-time monitoring of intraocular pressure (IOP) changes is impossible. This invention provides a device for simultaneous IOP monitoring during postoperative massage for glaucoma surgery, along with its usage method. The device features a movable massage head that avoids the drainage valve and filtration channel, maintaining a suitable distance to massage both sides of the filtration channel, promoting scar softening and diffusion. The massage head is connected to a pressure sensor for real-time pressure monitoring, and a screen displays the pressure change curve, providing a reliable basis for evaluating massage effectiveness and adjusting parameters. The device also features upper and lower supports to effectively adjust and fix the massage head's contact with the eyeball, preventing vibration and ensuring safety during the massage operation. Furthermore, it allows for the selection of single or double massage heads depending on the surgical procedure, offering multiple massage modes and functions to effectively alleviate postoperative eye discomfort and improve user comfort and satisfaction. The specific technical solution is as follows:

[0008] A device for detecting intraocular pressure changes during massage after glaucoma surgery, the device includes a front massage unit and a rear handle unit, the front massage unit being connected to the rear handle unit; the front massage unit includes a massage head moving component and a front support rotating component;

[0009] The massage head moving assembly includes a massage head 1, a front sleeve 2, a spring 3, a push rod 4, a pressure sensor 5, a rotating cam 6, and a bearing 7. Two massage heads 1 are connected and fixed to two corresponding push rods 4 by threads. The push rods 4 are "T" shaped push rods. Each push rod 4 is fitted with a spring 3. The two ends of the spring 3 are pressed between the front sleeve 2 and the push rod 4. The rear end of the push rod 4 contacts the pressure sensor 5. During massage, the massage head 1 contacts the junction of the eye socket and the eyeball to provide a pushing force to the push rod 4, pressing it against the surface of the pressure sensor 5. The pressure is detected by the pressure sensor 5 and a signal is transmitted. The back of the pressure sensor 5 is bonded to the rotating cam 6. The rotating cam 6 is installed in the inner ring of the bearing 7 by interference fit. The outer ring of the bearing 7 is fixed to the inner surface of the front sleeve 2.

[0010] The front-end support rotating assembly includes a rotating handle 101, supports 102, a front rotating seat 104, a gear mechanism 105, an upper fixed seat 106, an upper rotating nut 107, a lower fixed seat 108, a lower rotating nut 109, a gear connecting rod 110, and a gear bearing 111. The rotating handle 101 passes through the central through hole of the front rotating seat 104 and is mounted on the gear mechanism 105. The front rotating seat 104 is engaged with the gear mechanism 105, and the central disc surface of the front rotating seat 104 has an arc-shaped channel at the center. Two supports 102 pass through the two sides of the front rotating seat 104 and are respectively connected to the upper rotating nut 107. The upper rotating nut 107 is installed on the rotating bearing of the upper fixed seat 106, and the lower rotating nut 109 is installed on the rotating bearing of the lower fixed seat 108. The upper fixed seat 106 and the lower fixed seat 108 are fixedly connected to the front rotating seat 104 by bolts. The extension length of the supports 102 on both sides is adjusted by rotating the upper rotating nut 107 and the lower rotating nut 109, thereby adjusting the distance between the massage head 1 and the eyeball. The gear connecting rod 110 is inserted into the gear mechanism 105 and the gear bearing 111 respectively by interference fit. The gear bearing 111 is installed on the front sleeve 2.

[0011] In the aforementioned technical embodiment, the gear mechanism 105 includes an internal gear 201, a moving gear 202, and an external gear 203. The internal gear 201 is located at the center of the gear mechanism 105, meshing with the moving gear 202, and the moving gear 202 meshing with the internal teeth of the external gear 203. The gear connecting rod 110 is inserted into the center of the internal gear 201. The rotating handle 101 is mounted on the internal gear 201. One massage head 1 passes through the arc-shaped channel of the front rotating seat 104 and connects to the corresponding push rod 4, which is a relatively fixed massage head 1. The other massage head 1 passes through the arc-shaped channel of the front rotating seat 104 and the center hole of the moving gear 202 and connects to the corresponding push rod 4, which is a relatively movable massage head 1.

[0012] The operation of the rotating handle 101 drives the internal gear 201 to rotate, which in turn causes the moving gear 202 to rotate and move, thereby driving the relatively moving massage head 1 to move along the arc-shaped channel of the front rotating seat 104. The distance between the two massage heads 1 is adjusted to avoid the drainage valve and filter channel in the middle, and to massage the eyeballs on both sides of the drainage valve and filter channel. The front end of the front sleeve 2 is also provided with a fixing hole and an arc-shaped channel for passing through the push rod 4 and supporting the movement of the push rod 4.

[0013] In the above-mentioned technical solution, the front rotating seat 104 is secured to the outer edge of the external gear 203 by a set screw 301, a D4 spring 302 and a metal ball 303; that is, the set screw 301 is installed in the slot of the front rotating seat 104, the metal ball 303 is secured to the outer edge of the external gear 203, and the D4 spring 302 is compressed between the metal ball 303 and the set screw 301.

[0014] In the aforementioned technical solution, the front rotating seat 104 is also covered with a bolt plug 103 at the bolt fixing holes of the upper fixed seat 106 and the lower fixed seat 108 to block the exposed bolt heads.

[0015] In the aforementioned technical embodiment, the rear handle portion includes a motor 8, an electronic control board 9, a handle housing 10, a housing cover 11, and a touch display screen 12. The handle housing 10 is fixed to the rear end of the front sleeve 2 using a snap-fit ​​structure, facilitating the replacement of the front massage unit. The motor 8 and the electronic control board 9 are fixed to the inner cavity of the handle housing 10 by bolts. The touch display screen 12 is mounted on the handle housing 10 and is used for human-machine interaction and displaying pressure change curves. The housing cover 11 is mounted on the handle housing 10 using snap-fits and bolts to seal the inner cavity of the handle housing 10. The touch display screen 12 is electrically connected to the electronic control board 9, and the electronic control board 9 is electrically connected to the motor 8. The handle housing 10 is equipped with a Type-C charging port for charging the battery on the electronic control board 9. The battery supplies power to the touch display screen 12, the electronic control board 9, and the motor 8.

[0016] In the above-mentioned technical solution, the electronic control board 9 receives button commands from the touch screen 12, generates corresponding control signals according to the command requirements, and then amplifies them to generate drive signals, thereby driving the motor 8 to rotate at a certain frequency and amplitude; the electronic control board 9 receives pressure signals from the pressure sensor 5, records and outputs pressure change curves to the touch screen 12 for display, and judges the increase or decrease of intraocular pressure value based on the curve changes.

[0017] In the aforementioned technologies, the main chip of the electronic control board 9 uses the STM32F103C8T6, a 32-bit microcontroller chip based on the ARM Cortex-M3 core launched by STMicroelectronics. It has a maximum operating frequency of 72MHz and features 3 USART interfaces, 2 SPI interfaces, 2 IIC interfaces, 1 CAN interface, 1 advanced timer, 3 general-purpose timers, and 37 general-purpose I / O ports. When driving motor 8, the control chip employs optocoupler isolation, and the button circuit undergoes filtering to eliminate bounce.

[0018] The control program adopts a modular design. Based on the actual functional attributes of the massager, the control system is divided into three operating states: power-on state, idle state, and execution state. The relationship between the three states and the conditions for entering a state are set.

[0019] In the aforementioned technical solution, the pressure sensor 5 is in the form of a thin sheet.

[0020] In the above technical solution, the bolt plug 103 is made of rubber.

[0021] The method of using the above-mentioned device for detecting intraocular pressure changes during massage after glaucoma surgery includes the following steps:

[0022] S1: First, the current actual intraocular pressure value is detected by the tonometer, and the actual intraocular pressure value is input into the device information through the touch screen 12 as the initial intraocular pressure record;

[0023] S2: Depending on the different surgical methods for glaucoma, choose to install either a single-sided massage head 1 or a double-sided massage head 1; for a single-sided massage head 1, choose to install either a relatively fixed massage head 1 or a relatively movable massage head 1.

[0024] S3: Set the massage mode. The massage intensity is adjusted by the rotation speed and rotation angle of motor 8. The speed adjustment and forward / reverse rotation of motor 8 make the massage head 1 press at a constant speed or accelerate. The rotation angle of motor 8 controls the intensity of the massage head 1.

[0025] S4: Start the massage. During the massage, the eyeball provides a pushing force to the push rod 4 through the massage head 1. The rear end of the push rod 4 contacts the surface of the pressure sensor 5, generating a real-time detection pressure value that is transmitted to the electronic control board 9. The board records and obtains the pressure change curve. That is, the intraocular pressure value is based on the initial intraocular pressure. The pressure detected by the pressure sensor 5 generates a change curve, which is displayed on the touch screen 12. The massage effect is judged by the curve change, and the massage parameters are adjusted in time.

[0026] S5: Massage ends.

[0027] The present invention provides a device for detecting intraocular pressure changes simultaneously during postoperative massage in glaucoma patients, and its method of use. Compared with the prior art, the advantages of this device are as follows:

[0028] I. The device of this invention is designed with two massage heads. One of the massage heads can be moved relatively by rotating the handle. The distance between the two massage heads can be adjusted to avoid the drainage valve and filter channel in the middle without damaging them. This allows for massage on both sides of the filter channel, relieving the tension of scar tissue, promoting the softening and spread of scars, and significantly improving the speed and effect of postoperative recovery.

[0029] Second, the massage head of this invention is designed to contact a pressure sensor via a push rod. During massage, the pressure exerted by the eyeball on the massage head is transmitted to the pressure sensor, thereby enabling real-time detection of pressure changes and plotting of pressure change curves. This provides a reliable basis for evaluating the massage effect and adjusting parameters, preventing blind massage and the occurrence of side effects.

[0030] Third, the device of this invention is designed with a touch screen, which can perform operation input and display parameters such as change curves, so as to more intuitively observe and evaluate the massage effect.

[0031] Fourth, the device of this invention is designed with upper and lower supports for the eyeballs. The two supports are designed vertically, which will not hinder the operation of rotating the handle and the movement of the massage head. The upper and lower supports can effectively adjust and fix the contact between the massage head and the eyeballs, and can also prevent shaking, ensuring the safety of the massage operation.

[0032] V. The device of this invention features a portable and lightweight design, making it convenient for patients to use at home. Patients can easily perform massages at home or in their daily lives. Doctors only need to provide simple post-operative guidance, supplemented by appropriate instructions and operating manuals, allowing patients to easily master the usage method and conveniently perform self-massage. This effectively reduces the workload of doctors; it also eliminates the need for complete reliance on doctors and medical equipment, significantly saving medical resources.

[0033] VI. The device of this invention is an automated massage operation. Massage is performed through a preset program, reducing reliance on manual massage. Instrumental massage ensures the accuracy and consistency of massage movements, effectively reducing errors caused by human factors. Furthermore, it can complete the massage task in a short time without requiring prolonged involvement from professional personnel, thus improving massage efficiency and saving human resources.

[0034] VII. This invention's device can precisely control the intensity, adjusting the massage strength and frequency according to the patient's needs and condition, making the massage process more precise and personalized, and meeting the special needs of different patients. It can also be equipped with either a single-sided or double-sided massage head depending on the surgical procedure. The device has multiple massage modes and functions, providing different massage methods and effects. Through gentle and soothing massage, it can effectively relieve postoperative eye discomfort, improve user comfort and satisfaction, and has good practical value. Attached Figure Description
