Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and particularly relates to a driving device, a vitreous cutter device and an ultrasonic emulsification device. Background Art

[0002] The vitreous body is a colorless and transparent colloid, located in the vitreous cavity behind the lens, accounting for 4 / 5 of the volume of the eye contents. The vitreous body is in a gel state and is composed of 98.5%-99.7% water, collagen fibers, hyaluronic acid and vitreous cells. The volume of the vitreous body in an adult is about 4 ml, and in highly myopic eyes, the volume of the vitreous body can increase to 10 ml.

[0003] The vitreous cutter in ophthalmology is a microsurgical ophthalmic operation developed in the 1970s of the last century. Nowadays, its status in ophthalmic surgery is second only to cataract extraction and intraocular lens implantation, bringing light to countless patients with eye diseases. The basic function of vitreous cutter is to remove the turbid vitreous body or remove the vitreoretinal traction, restore the transparent refractive medium and promote the retinal reattachment, treat vitreoretinal diseases, and restore the visual function of patients.

[0004] The vitreous cutter is mainly used for cutting and aspirating the vitreous body. Currently, the pneumatic vitreous cutter widely used on the market mainly uses compressed air as the power source, supplemented by a high-frequency reversing valve to control the high-speed reciprocating axial movement of the cutting probe, and then cuts the diseased tissue through the guillotine-type notch outside the probe, and uses a peristaltic pump or a vacuum pump to aspirate the cut diseased tissue.

[0005] At present, there are two ways to drive the pneumatic handle of the vitreous cutter on the market. One is to connect an external gas source component (such as a gas cylinder), and equip a filtering device, a sensor and a reversible solenoid valve to achieve the reciprocating movement of the probe at the handle end; however, this driving method requires an external gas source component and has certain requirements for the surgical scenario. The other way is to generate compressed gas through an air pump, and equip a heat dissipation device, a filtering device, a sensor and a solenoid valve to achieve the reciprocating movement of the probe at the handle end; however, this driving method has several problems: (1) The assembly connection process of the air pipes between the components is cumbersome and requires a large assembly space; (2) There may be multiple gas leakage paths, which are likely to cause instability of the driving system and are not conducive to troubleshooting. Summary of the Invention

[0006] The purpose of the present invention is to provide a driving device, a vitreous cutter device and an ultrasonic emulsification device.

[0083] In some embodiments of the present invention, the commutation member 5 is fixed to the gas path integration member 10 through a fixing plate 20.

[0084] In some embodiments of the present invention, the commutation member is a two-position five-way solenoid valve.

[0085] In some embodiments of the present invention, the driving device further includes a throttle valve 30. The throttle valve 30 is fixed to the gas path integration member 10 by a thread and is connected to the commutation member 5. The throttle valve 30 is used to adjust the flow rate and pressure of the commutation member 5.

[0086] In some embodiments of the present invention, refer to Figures 1 to 3, the driving device further includes a first pressure sensor 91, the first pressure sensor 91 is detachably connected to the connecting pipeline between the second gas path control member 3 and the flow control member 4 to monitor the first real-time pressure value in the connecting pipeline, and the control module 6 is connected to the first pressure sensor 91. The control module 6 is used to control the start and stop of the gas source member 7 according to the comparison result between the first real-time pressure value and the preset pressure value. Since the connecting pipeline between the second gas path control member 3 and the flow control member 4 is exposed outside the gas path integration member 10, the first pressure sensor 91 is detachably connected to the connecting pipeline between the second gas path control member 3 and the flow control member 4, which is more convenient for installation and maintenance, reduces the volume of the gas path integration member 10, and has better airtightness.

[0087] Specifically, when the gas source member 7, the first gas path control member 1, the gas storage tank 2, the second gas path control member 3, and the flow control member 4 are connected in sequence, the pressure in the entire pipeline is the same. Therefore, the first pressure sensor 91 is connected to the connecting pipeline between the second gas path control member 3 and the flow control member 4 to monitor the first real-time pressure value in the connecting pipeline, so as to realize the monitoring of the pressure value in the entire pipeline.

[0088] In some other embodiments of the present invention, the first pressure sensor 91 is connected to the connecting pipeline between the first gas path control member 1 and the gas storage tank 2.

[0089] In some other embodiments of the present invention, the first pressure sensor 91 is connected to the connecting pipeline between the second gas path control member 3 and the gas storage tank 2.

[0090] In some embodiments of the present invention, the first pressure sensor 91 is a plug-in pressure sensor.

[0091] In some specific embodiments of the present invention, refer to Figure 2 , Figure 4 and Figure 7 , there is an insertion interface 36 between the second external interface 321 and the third external interface 411, and the first pressure sensor 91 is inserted into the insertion interface 36.

[0092] In some specific embodiments of the present invention, the control method of the driving device includes the following steps:

[0093] S11. The first pressure sensor 91 monitors the first real-time pressure value in the connecting pipeline between the second gas path control member 3 and the flow control member 4 and sends it to the control module 6;

[0094] S12. The control module 6 receives the first real-time pressure value and compares and analyzes the first real-time pressure value with a preset pressure value; and when the first real-time pressure value is less than the preset pressure value, the control module 6 sends a start gas supply instruction to the gas source component 7, and when the first real-time pressure value is equal to the preset pressure value, the control module 6 sends a stop gas supply instruction to the gas source component 7;

[0095] S13. The control module 6 controls the start and stop of the gas source component 7 according to the start gas supply instruction or the stop gas supply instruction.

[0096] In some embodiments of the present invention, the control module 6 controls the first gas path control component 1 to be powered on or off according to the start gas supply instruction or the stop gas supply instruction.

[0097] In some embodiments of the present invention, refer to Figure 2 、 Figure 4 and Figure 10 , the driving device further includes a second pressure sensor 92 and a third pressure sensor 93. The second pressure sensor 92 is disposed on the first driving gas output pipeline 52 to monitor a second real-time pressure value in the first driving gas output pipeline 52, and the third pressure sensor 93 is disposed on the second driving gas output pipeline 53 to monitor a third real-time pressure value in the second driving gas output pipeline 53. And the control module 6 is respectively connected to the second pressure sensor 92 and the third pressure sensor 93. The control module 6 is used to judge whether the first driving gas output pipeline 52 and the second driving gas output pipeline 53 are connected to the driven according to a comparison result between a pressure difference between the second real-time pressure value and the third real-time pressure value and a preset threshold value.

[0098] In some specific embodiments of the present invention, the control method of the driving device includes the following steps:

[0099] S21. The second pressure sensor 92 monitors a second real-time pressure value in the first driving gas output pipeline 52 and sends it to the control module 6; the third pressure sensor 93 monitors a third real-time pressure value in the second driving gas output pipeline 53 and sends it to the control module 6

[0100] S22. The control module 6 receives the second real-time pressure value and the third real-time pressure value, and after calculating the pressure difference between the second real-time pressure value and the third real-time pressure value, compares and analyzes the pressure difference with a preset threshold value;

[0101] S23. When the pressure difference is within a preset threshold, the control module 6 determines that the first driving gas output pipeline 52 and the second driving gas output pipeline 53 are already connected to the driven part. The control module 6 transmits this connection information to the output module for display or broadcast, so as to facilitate the user to perform the next operation, such as starting the gas source part 7, etc.

The probe 300 is disposed on a diaphragm 400 between the first gas accommodation chamber 100 and the second gas accommodation chamber 200. The first driving gas path and the second driving gas path are respectively connected to the first gas accommodation chamber 100 and the second gas accommodation chamber 200, so that the first gas accommodation chamber 100 and the second gas accommodation chamber 200 alternately inflate and deflate, thereby driving the diaphragm 400 to drive the probe 300 to perform reciprocating axial movement along the length direction of the probe 300.

The cutting handle includes two gas accommodation chambers and a probe. The probe is disposed on a diaphragm between the two gas accommodation chambers. The first driving gas path and the second driving gas path are respectively connected to the two gas accommodation chambers, so that the two gas accommodation chambers alternately inflate and deflate, thereby driving the diaphragm to drive the probe to perform reciprocating axial movement along the length direction of the probe.
