Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a surge detection device in ophthalmic surgery, a phacoemulsification handle and ophthalmic surgery flushing equipment. Background Art

[0002] The fragments cut off during vitrectomy and phacoemulsification surgery in ophthalmology are removed by fluid flow. The fluid flow includes irrigation fluid flow and suction fluid flow, which are used to flush these fragments out of the eyeball through fluid circulation.

[0003] During the operation, the blockage of the vitrectomy needle and the phacoemulsification needle, as well as the patency after the blockage is removed, will cause the sudden interruption and resumption of fluid flow, resulting in huge volume changes and pressure changes inside the eyeball, causing the thin-walled capsule of the eyeball and the cutting needle (emulsification needle) to contact and be damaged, causing surgical risks. This change in volume and intraocular pressure is called surge. When surge occurs, surgical instruments are required to immediately increase and decrease the amount of fluid injected to compensate for the volume change in the eye, thereby achieving the purpose of controlling intraocular pressure.

[0004] Ophthalmic surgical instruments are divided into two parts in terms of fluid path: the main unit and the handle. The main unit and the handle are connected by a hose several meters long to allow the fluid to flow. Current ophthalmic surgical instruments all use the method of detecting changes in liquid pressure or flow on the main unit to detect the surge in the eyeball. The main unit and the handle are connected by a hose several meters long, which is a certain distance away. There will be a large delay in the transmission of pressure and flow from the eyeball to the main unit. Summary of the invention

[0038] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1

[0040] like Figure 1 As shown, the surge detection device for ophthalmic surgery provided by the embodiment of the present invention includes: a handle. During the operation, the operator holds the handle and the handle is close to the patient's eyes.

[0041] The handle is provided with a cavity formed by a hard shell 100. The shell 100 may be made of hard medical plastic, and the shell 100 itself does not deform during the liquid circulation process.

[0042] The cavity is connected with an elastic diaphragm 200, and the elastic diaphragm 200 divides the cavity into a perfusion cavity 110 and a suction cavity 120. The elastic diaphragm 200 material includes but is not limited to a stainless steel sheet or a soft rubber diaphragm. In this embodiment, the elastic diaphragm 200 material is a soft rubber diaphragm.

[0043] The housing 100 may be in a rectangular parallelepiped or cylindrical shape but is not limited thereto. The housing 100 is provided with a first inlet 310 and a first outlet 320 respectively connected to the perfusion chamber 110; the housing 100 is provided with a second inlet 410 and a second outlet 420 respectively connected to the suction chamber 120. The first inlet 310 and the second outlet 420 are on the same side, and the first outlet 320 and the second inlet 410 are on the same side.

[0044] A detection mechanism is provided in the cavity, and the detection mechanism is used to detect the deformation amount of the elastic diaphragm 200 changing into the perfusion cavity 110 or the suction cavity 120. That is to say, when the pressure difference between the perfusion cavity 110 and the suction cavity 120 changes, the elastic diaphragm 200 will move into one of the two.

[0045] When the fluid flow is normal during surgery and no surge occurs, the pressure ratio of the perfusion chamber 110 and the suction chamber 120 should be a balanced value, and the elastic diaphragm 200 usually stays at a certain position in the middle. When surge occurs, there are two situations. One is that the suction needle is blocked, the pressure in the perfusion chamber 110 drops rapidly, and the pressure of the perfusion chamber 110 increases due to the obstruction of the liquid path, and the elastic diaphragm 200 moves toward the suction chamber 120. The second is that when the blockage is removed, the pressure of the suction chamber 120 rises rapidly, and the liquid in the perfusion chamber 110 suddenly flows, causing the pressure to drop, thereby causing the elastic diaphragm 200 to move toward the perfusion chamber 110. By detecting the direction in which the diaphragm moves, the surge phenomenon can be accurately detected. Since the device is located at the handle end, close to the eyeball, and the movement of the elastic diaphragm 200 itself is determined by the reverse suction and perfusion pressures, it can more quickly respond to changes in pressure in the eyeball and more quickly indicate the occurrence of surge.

[0046] In this embodiment, the detection mechanism includes a first metal sheet 510, a second metal sheet 520 and a third metal sheet 530 arranged in parallel, wherein the arrangement direction of the first metal sheet 510, the second metal sheet 520 and the third metal sheet 530 is perpendicular to the flow direction of the liquid. In this embodiment, the first metal sheet 510 is arranged on the elastic diaphragm 200; specifically, the elastic diaphragm 200 may include a soft rubber diaphragm located on the outside, and the soft rubber diaphragm may have two layers, forming a hollow cavity between the two layers, and the first metal sheet 510 is clamped in the hollow cavity. When the pressure difference between the perfusion cavity 110 and the suction cavity 120 changes, the soft rubber diaphragm is deformed and moves left and right together with the first metal sheet 510.

[0047] The second metal sheet 520 is arranged on the side wall of the perfusion chamber 110, and the third metal sheet 530 is arranged on the side wall of the suction chamber 120. Specifically, the second metal sheet 520 and the third metal sheet 530 can be connected to two opposite outer walls of the shell 100 respectively. The second metal sheet 520 and the third metal sheet 530 can be connected to the shell 100 respectively by adhesive or card slot. Since the second metal sheet 520 and the third metal sheet 530 are located on the outer wall of the shell 100, and the first metal sheet 510 is located on the inner side of the soft rubber film, the first metal sheet 510, the second metal sheet 520 and the third metal sheet 530 are not in contact with the liquid. Therefore, the first metal sheet 510, the second metal sheet 520 and the third metal sheet 530 are not easily corroded and damaged, and have higher sensitivity.

[0048] The first metal sheet 510, the second metal sheet 520 and the third metal sheet 530 are all connected to the capacitance detection mechanism through the cable 540, and the capacitance detection mechanism is used to detect the capacitance between the first metal sheet 510 and the second metal sheet 520, and the first metal sheet 510 and the third metal sheet 530. There will be a capacitor C1 between the first metal sheet 510 and the second metal sheet 520. Similarly, there will be a capacitor C2 between the first metal sheet 510 and the third metal sheet 530. When the elastic diaphragm 200 moves toward the perfusion chamber 110, C1 increases and C2 decreases. When the elastic diaphragm 200 moves toward the suction chamber 120, C1 decreases and C2 increases. By detecting C1 and C2, it is possible to quickly determine in which direction the elastic diaphragm 200 moves, thereby determining whether a surge occurs.

[0049] The surge detection device for ophthalmic surgery includes a first tube body connected to the first inlet 310, a second tube body connected to the first outlet 320, a third tube body connected to the second inlet 410, and a fourth tube body connected to the second outlet 420. The first tube body and the second tube body are respectively connected to the opening of the main machine perfusion pipeline and the opening of the handle perfusion pipeline. The third tube body and the fourth tube body are respectively connected to the opening of the main machine suction pipeline and the opening of the handle suction pipeline.

[0050] In an practicable solution, the first inlet 310 and the first tube body, the first outlet 320 and the second tube body, the second inlet 410 and the third tube body, and the second outlet 420 and the fourth tube body may all be connected by interference fit.

[0051] In another practicable solution, the first inlet 310 and the first tube body, the first outlet 320 and the second tube body, the second inlet 410 and the third tube body, and the second outlet 420 and the fourth tube body are all detachably connected; the detection mechanism and the main controller are connected via a plug jack. The housing 100 can be removed from each tube body to facilitate replacement and maintenance of the accessory. For example, the first inlet 310 and the first tube body, the first outlet 320 and the second tube body, the second inlet 410 and the third tube body, and the second outlet 420 and the fourth tube body are all connected via threads.

[0052] The caliber of the first inlet 310 is larger than that of the second inlet 410, and the caliber of the first outlet 320 is larger than that of the second outlet 420. Therefore, only when the first inlet 310 is docked with the first tube body and the first outlet 320 is docked with the third tube body, can the docking be achieved, which can play a fool-proof effect and avoid incorrect connection between the perfusion chamber 110 and the suction chamber 120.

[0053] Example 2

[0054] like Figure 2As shown, in this embodiment, the elastic diaphragm 200 itself is a metal sheet, such as a stainless steel sheet, and the elastic diaphragm 200 forms the first metal sheet 510, the edge of the first metal sheet 510 is connected to the inner wall of the housing 100, and is used to separate the perfusion chamber 110 and the suction chamber 120. The second metal sheet 520 is arranged on the side wall of the perfusion chamber 110, and the third metal sheet 530 is arranged on the side wall of the suction chamber 120. Specifically, the second metal sheet 520 and the third metal sheet 530 can be respectively connected to two opposite outer walls of the housing 100. The second metal sheet 520 and the third metal sheet 530 can be respectively connected to the housing 100 by means of adhesive or slots. Since the second metal sheet 520 and the third metal sheet 530 are located on the outer wall of the housing 100, and the first metal sheet 510 is located on the inner side of the soft plastic film, the first metal sheet 510, the second metal sheet 520 and the third metal sheet 530 are not in contact with the liquid, so the first metal sheet 510, the second metal sheet 520 and the third metal sheet 530 are not easily corroded and damaged, and have higher sensitivity. The first metal sheet 510, the second metal sheet 520 and the third metal sheet 530 are all connected to the capacitance detection mechanism through the cable 540, and the capacitance detection mechanism is used to detect the capacitance between the first metal sheet 510 and the second metal sheet 520, and the first metal sheet 510 and the third metal sheet 530. There will be a capacitor C1 between the first metal sheet 510 and the second metal sheet 520. Similarly, there will be a capacitor C2 between the first metal sheet 510 and the third metal sheet 530. When the elastic diaphragm 200 moves toward the perfusion chamber 110, C1 increases and C2 decreases, and when the elastic diaphragm 200 moves toward the suction chamber 120, C1 decreases and C2 increases. By detecting C1 and C2, it is possible to quickly determine in which direction the elastic diaphragm 200 moves, thereby determining whether surge flow occurs.

[0055] like Figure 3 As shown, the phacoemulsification handle provided by the present invention includes the above-mentioned surge detection device during ophthalmic surgery. Since the surge detection device during ophthalmic surgery is located at the end of the handle, close to the eyeball, and the movement of the elastic diaphragm 200 itself is determined by the reverse suction and irrigation pressure, it can more quickly respond to changes in intraocular pressure and more quickly indicate the occurrence of surge.

[0056] The phacoemulsification handle includes a first suction pipe 610, a hose 620, a second suction pipe 630 and an ultrasonic transducer 640; the ultrasonic transducer 640 surrounds the outside of the first suction pipe 610; the distal end of the first suction pipe 610 is connected to the proximal end of the hose 620, the distal end of the hose 620 is connected to the second inlet 410 of the surge detection device during ophthalmic surgery, and the second outlet 420 of the surge detection device during ophthalmic surgery is connected to the proximal end of the second suction pipe 630.

[0057] In this solution, the first suction pipe 610 and the surge detection device during ophthalmic surgery are connected by a hose 620, which can prevent the ultrasonic transducer 640 from transmitting vibration to the surge detection device during ophthalmic surgery when working, thereby affecting the measurement accuracy of the surge detection device during ophthalmic surgery.

[0058] The ultrasonic transducer 640 and the cable 540 of the surge detection device during ophthalmic surgery are led out from the same electrical interface 670 .

[0059] The handle further has a perfusion pipeline 650 and a perfusion interface 660 . The perfusion pipeline 650 is in communication with the first outlet 320 , and the perfusion interface 660 is in communication with the first inlet 310 .

[0060] The ophthalmic surgery flushing device provided by the present invention includes the above-mentioned surge detection device during ophthalmic surgery. Because the ophthalmic surgery flushing device provided by the embodiment of the present invention uses the above-mentioned surge detection device during ophthalmic surgery, the ophthalmic surgery flushing device provided by the embodiment of the present invention also has the advantages of the surge detection device during ophthalmic surgery.

[0061] The ophthalmic surgery flushing device also includes a main body connected to the handle, and a liquid pump and other structures are arranged in the main body.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
