[0002] Cataract has become the leading cause of blindness in the world. Cataract surgery is the most effective way to treat cataract patients. Phacoemulsification is the most mature surgical model for cataract treatment.

[0003] Phacoemulsification surgery uses a scalpel to make an incision in the cornea and anterior capsule, and uses a phacoemulsification device to suck out the cloudy lens. The ultrasound generated by the phacoemulsification device can effectively break up the cloudy lens and suck out the broken lens through the channel.

[0004] However, the ultra-high frequency vibration of the phacoemulsification handle will cause additional thermal damage to the surrounding tissues, especially the corneal endothelial cells, in the process of breaking up the cloudy lens. During the phacoemulsification operation, the higher the degree of cataract opacity, the longer the high-frequency emulsification time and intensity, the higher the heat accumulation, and the greater the thermal damage to the corneal endothelial cells. Especially in the operation of hard nuclear cataract and opalescent nuclear cataract, the energy required is extremely high, and the endothelial cell loss rate of patients after the operation is extremely high.

DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with 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. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0046] The contents involved in the above embodiment are described below in conjunction with a preferred embodiment.

[0047] Embodiment 1

[0048] like Figure 1 As shown, the present invention provides a crushing and suction operation handle for cataract surgery, comprising: a piezoelectric vibrator 14 and an extraction channel 11, an injection channel 12 and an illumination channel 13 running through the operation handle;

[0049] The extraction channel 11 is arranged at the center of the operating handle 1. The extraction channel 11 is a hollow pipe. One end of the extraction channel 11 has a preset curvature and is used to connect a cutter head 18 with a blunt edge. The piezoelectric vibrator 14 is used to drive the cutter head 18 to vibrate horizontally to cut and break the lens.

[0050] A peristaltic pump (not shown) is disposed at the other end of the extraction channel 11 to suck out the broken lens fragments in the lens capsule under the suction pressure generated by the peristaltic pump;

[0051] The injection channel 12 is a hollow pipe, one end of which enters the patient's eyeball during surgery, and the other end of which is connected to a water pump (not shown) to inject medical liquid into the patient's eye during surgery to maintain intraocular pressure balance during surgery;

[0052] The illumination channel 13 is an optical fiber structure, which is used to transmit light of a specific wavelength during surgery to illuminate the surgical area.

[0053] The present invention proposes a fragmentation and suction operation handle for cataract surgery, which has the following functions: (a) achieving cataract lens nucleus fragmentation; (b) sucking out the broken cataract lens fragments from the lens capsule; (c) continuous liquid injection during the operation to maintain intraocular pressure; the liquid is an ophthalmic medical liquid such as balanced saline; (d) intraoperative fiber optic illumination to determine residual cataract fragments; (e) the flow rate of the extraction channel and the injection channel can be controlled by a computer to maintain constant intraocular pressure.

[0054] like Figure 1 As shown, the blade 18 is fixed to the top of the extraction channel 11, and the extraction channel 11 is fixed to the piezoelectric vibrator 14. The piezoelectric vibrator 14 is controlled to vibrate by a signal, driving the blade 18 to vibrate at a high frequency and a low frequency; the blade 18 used has a blunt edge, and the blade 18 vibrates horizontally to break the lens in the lens capsule without damaging the surrounding corneal endothelial cells. The vibration direction of the piezoelectric vibrator 14 is consistent with that of the blade 18.

[0055] The length of the extraction pipe 11 is greater than that of the injection channel 12 and the illumination channel 13. The extraction pipe 11 has a preset curvature on the side close to the lens. In this embodiment, the curvature ranges from 10 to 30 degrees, which facilitates its deep penetration into the lens during surgery. The peristaltic pump generates suction pressure to suck out the broken lens fragments in the capsule from the hollow pipe. The extraction pressure of the peristaltic pump can be set and controlled according to actual needs.

[0056] like Figure 1 As shown, the injection channel 12 is arranged above the extraction pipe 11. During the operation, one end of the injection channel 12 goes deep into the patient's eyeball, and the other end is connected to a water pump. The liquid is an ophthalmic medical liquid such as balanced saline. During the operation, the liquid is continuously injected to maintain the intraocular pressure. The amount of water injected into the injection channel can be controlled by controlling the flow rate of the water pump.

[0057] like Figure 1 As shown, the illumination channel 13 is arranged above the injection channel 13, and during the operation, the light of a specific wavelength is illuminated to detect the situation in the capsular bag; by using the specific wavelength light illumination, it is easier to distinguish whether there are cataract fragments remaining in the capsular bag with the naked eye. One end of the optical fiber is connected to the laser to generate specific illumination light, and the illumination light intensity and illumination light band can be set according to needs.

[0058] Optionally, the light of the specific wavelength is ultraviolet light, visible light or infrared light. In a preferred embodiment, blue light is used, and debris is easier to find under blue light.

[0059] Furthermore, the water pump and peristaltic pump connected to the injection channel 12 and the extraction channel 11 have built-in sensors, which can obtain flow in real time. The flow of the water pump and peristaltic pump is analyzed and controlled by a computer to achieve the balance of the inflow and outflow of the intraocular fluid and maintain the intraocular pressure.

[0060] In the embodiment of the present invention, a vibrating blade with a blunt edge is used to cut and crush the lens. Since the blade edge is blunt, it will not cause cutting damage to the eye tissue, and the vibrating blade does not require ultrasonic vibration frequency to cut the lens, reducing the additional thermal damage caused by ultrasound during the lens crushing process; it solves the problem of large thermal damage to the patient's corneal endothelial cells during cataract surgery, and improves the accuracy of surgical operations, and improves the success rate and safety of the operation. The fiber optic lighting structure is integrated in the operating handle, and the specific light wavelength is used for illumination, which can effectively detect the fragments after the cataract is broken during the operation, making it convenient for doctors to observe whether there are residual cataract fragments in the capsule after surgery, thereby improving the safety of the operation.

[0061] like Figures 2 to 5 As shown, optionally, the cutter head 18 is a double-edged cutter head;

[0062] The double-edged blade head is composed of a sleeve 182 and a blade 181, wherein the blade 181 includes a left blade and a right blade, which are respectively fixedly connected to the two sides of the sleeve 182, and the left blade and the right blade are located in the same plane; the sleeve 182 is a front and rear opening structure, and the sleeve 182 is sleeved to one end of the extraction pipe 11 with a preset curvature.

[0063] The double-edged blade head is mounted on the front end of the extraction pipe 11 and can be used. Figure 2 is the xz section diagram of the operating handle. Figure 2 As shown, further, the front end of the sleeve 182 is flush with the front end of the extraction pipe 11. When the double-edged blade head is working, the direction of the double edges is the vibration crushing direction. The two-person blade head has higher cutting efficiency and is suitable for crushing hard-core lenses. After the cataract lens is crushed, it is sucked out of the lens capsule bag through the front port of the extraction pipe 11. When the double-edged blade head is working, the direction of the double edges is the vibration crushing direction. The two-person blade head has higher cutting efficiency and is suitable for crushing hard-core lenses.

[0064] like Figure 6 to Figure 7 As shown, optionally, the cutter head 18 is an arc cutter head;

[0065] The arc-shaped cutter head is composed of a sleeve 182, a suction hole 183 and a protective blade 184. The protective blade is in the shape of an elliptical cake and is arranged at one end of the sleeve 182. The suction hole 183 is arranged on the side of the sleeve 182. The sleeve 182 is connected to one end of the extraction pipe with a preset curvature.

[0066] The blade head of this structure is in the shape of an elliptical pancake, and the suction hole 183 is on the side of the tube sleeve 182. In the process of breaking up the cataract, the arc-shaped shield structure at the front end of the blade head of this structure can well protect the capsule from being damaged. Cataract fragments are sucked out through the suction hole 183 on the side. The arc-shaped blade head has better protection for the capsule and is suitable for removing cortical debris close to the capsule.

[0067] Optionally, the protective blade is made of medical metal, with a curvature radius of 2-15 mm and a diameter of 1-3 mm. In a specific embodiment, the front surface curvature radius of the protective blade is 5 mm, and the diameter of the protective blade is 1.5 mm, which can be closer to the curvature of the lens edge.

[0068] Optionally, the operating handle further includes a protective shell and an insulating vibration isolation support portion;

[0069] The protective shell is made of medical plastic material and is used to protect the injection channel, lighting channel, extraction channel and piezoelectric vibrator in the operating handle;

[0070] The insulating vibration isolation support part is made of medical plastic material and is used to fill the area in the operating handle except the injection channel, the lighting channel, the extraction channel and the piezoelectric vibrator, and has the functions of shock absorption and insulation.

[0071] The present invention improves the blade and vibration mode, and can achieve efficient cataract lens fragmentation at a lower vibration frequency, with less heat impact during fragmentation. It effectively reduces the thermal damage in phacoemulsification surgery. Secondly, under the illumination of a fiber optic light source of a specific wavelength, doctors can more effectively and conveniently find sebaceous debris attached to the capsule. It assists doctors in more effectively cleaning the debris in the capsule. It can effectively avoid the proliferation of residual sebaceous debris after surgery, which leads to the occurrence of secondary cataracts.
