Description

Technical Field

[0001] The present invention relates to a method for operating an ophthalmic surgical system. At least two first fluid lines for fluidly coupling a console of the ophthalmic surgical system to at least one medical treatment device of the ophthalmic surgical system are connected to the console. The at least two first fluid lines include at least one first cleaning line and at least one first suction line. The treatment device side ends of the at least two first fluid lines are fluidly coupled to each other. A treatment fluid is transported from a treatment fluid source through the at least two first fluid lines to a collection container of the ophthalmic surgical system using a console side pump container. The present invention also relates to an ophthalmic surgical system for treating an eye, having at least: at least one medical treatment device for treating the eye; a console for controlling the at least one medical treatment device during at least an intended operation; and at least two first fluid lines for fluidly coupling the console to the at least one medical treatment device. The at least two first fluid lines are connectable to the console and to the at least one medical treatment device. The at least two first fluid lines include at least one first cleaning line and at least one first suction line. The ophthalmic surgical system is designed to fluidly couple the treatment device side ends of the at least two first fluid lines to each other with the console connected, and to transport a treatment fluid from a treatment fluid source through the at least two first fluid lines to a collection container of the ophthalmic surgical system using a console side pump device.

[0002] Ophthalmic surgical systems, consoles therefor, and medical treatment instruments, specifically handpieces as well, and methods therefor are known in the prior art and thus in principle do not require any separate documentary evidence in this aspect. For the treatment of lens opacities, which are also medically known as cataracts, various surgical techniques are known. The most widespread technique is phacoemulsification, in which a thin hollow needle of a handpiece is introduced into the lens capsule in which the lens is located, and ultrasonic vibrations are induced. The lens can be emulsified using the vibrating hollow needle, and the relaxed lens particles in the process can be aspirated using a pump through a suction line. In the process, a cleaning fluid or a treatment fluid is supplied. The lens particles are aspirated together with this fluid as the suction fluid. As soon as the lens is completely emulsified and removed, a new artificial lens can be inserted into the now-empty lens capsule at that time. The treated patient can regain good vision with this method.

Background Art

[0003] An advanced ophthalmic surgical system that has been proven to be particularly suitable for phacoemulsification is disclosed, for example, in the German Patent Application Publication No. 102016201297B3. In this system, two fluid pumps of a pump device fluid-connected in parallel are used in each case for cleaning and for aspiration. Each of the fluid pumps has a pump chamber and a drive chamber separated by a partitioning element movably arranged from the pump chamber. For example, the partitioning element has an elastic design, can be firmly clamped, or can also be arranged displaceably between the chambers. To operate the fluid pump as intended, the drive chamber is subjected to the action of a drive fluid in which the drive pressure changes to execute each pump stroke. Depending on this, the deflection position of the partitioning element thus changes, which has an effect corresponding to the pump chamber. The pump chamber is subjected to the action of each treatment fluid, for example, a cleaning fluid, a suction fluid, or the like. The delivery act can then be achieved by appropriately controlling each inlet valve and each outlet valve of the fluid pump.

[0004] The deflection position of the partition element is detected using a deflection position sensor assigned to each fluid pump. The control device of the ophthalmic surgical system, specifically the console, controls the function of the fluid pump based on at least the sensor signal of the deflection position sensor and the drive pressure signal supplied using a drive pressure sensor. In addition, the control device can control, for example, the inlet valve and the outlet valve.

[0005] By the alternating operation of each two fluid pumps connected in parallel, a substantially constant volume flow rate can be obtained during the surgical operation. In this way, a substantially constant intraocular pressure can be obtained within the lens capsule. As long as sufficient suction fluid can be delivered, the system can operate with little interruption of the flow of the irrigation fluid even during a very prolonged surgical operation.

[0006] Starting from the non-use state, the therapeutic fluid is often injected into at least two first fluid lines for the purpose of using the ophthalmic surgical system before the ophthalmic surgical treatment is performed. Preferably, the therapeutic fluid should be injected substantially throughout the fluid line. To achieve this goal, the fluid line is connected to the console and the treatment instrument side ends of at least two first fluid lines are fluid-coupled. Immediately there, generally the console side pump device is used to transport the therapeutic fluid through at least two first fluid lines, so that they are preferably completely filled or rinsed with the therapeutic fluid. The treatment instrument side ends are then fluid-separated and the ends are coupled to the medical treatment instrument, particularly so that the medical treatment can be started.

[0007] The above-described operation start process generally needs to be manually executed again when the medical treatment instrument is changed during the medical treatment or when a further medical treatment instrument is used. This is time-consuming and in certain situations, it is obstructive during a medical treatment such as eye surgery. Summary of the Invention Problems to be Solved by the Invention

[0008] The object of the present invention is to improve an ophthalmic surgical system with respect to a method for operating the ophthalmic surgical system and for operating a medical treatment instrument.

Means for Solving the Problem

[0009] As a solution, the present invention proposes a method for treating an eye and an ophthalmic surgical system as set forth in the independent claims.

[0010] Advantageous development forms become apparent from the features of the dependent claims.

[0011] Regarding a general method, specifically, at least one second fluid line for a treatment fluid is connected to the side of the console to fluidly couple the console to at least one medical treatment instrument or a further medical treatment instrument, and the instrument-side end of the at least one second fluid line is fluidly coupled to at least one of the instrument-side ends of at least two first fluid lines, and the treatment fluid is conveyed through the at least one second fluid line using a side-of-console pump device.

[0012] Regarding a general ophthalmic surgical system, specifically, the ophthalmic surgical system includes at least one second fluid line for a treatment fluid, fluidly couples the console to at least one medical treatment instrument or a further medical treatment instrument, the ophthalmic surgical system fluidly couples the instrument-side end of the at least one second fluid line to at least one of the instrument-side ends of at least two first fluid lines, and is designed to convey the treatment fluid through the at least one second fluid line using a side-of-console pump device.

[0013] The present invention is particularly based on the idea of better assisting the user of an ophthalmic surgical system during intended use, for example during a medical treatment of the eye. The present invention can provide great assistance to the user or surgeon, especially when the medical treatment instrument is changed or when a further medical treatment instrument is operated during the intended use or the eye surgical procedure. For example, if the additional use of a second fluid line is required, for example when a further medical treatment instrument is operated, the treatment fluid must be injected into at least one second fluid line before the further medical treatment instrument can be used. If the treatment fluid is a treatment liquid, such as a cleaning liquid or the like, the fluid line should preferably not contain any gas or air bubbles. As a result, full and reliable functionality can already be achieved at the beginning of the use of the medical treatment instrument. Such a procedure is also called priming.

[0014] During surgery, priming has been found to be inconvenient for the user or surgeon when it interferes with the surgery, especially when the handpiece is used within the scope of ophthalmic surgery, as it can take several seconds and up to one and a half minutes. This can be avoided as a result of the present invention.

[0015] For example, the medical treatment instrument can be a handpiece for ophthalmic surgical treatment, within which the eye lens should be removed. However, this can also relate to a handpiece, a vitreous cutter or the like suitable for posterior eye surgery. As a general rule, such a medical treatment instrument is connected to the console using at least one suction line or at least one cleaning line, generally in the form of a tube.

[0016] These lines and the elements or units of the console into which the treatment fluid is injected are also rinsed, at least before intended use and / or optionally also during any surgical procedure being performed. This can be achieved within the scope of the treatment according to the invention. In this context, generally the treatment tool side ends of at least two first fluid lines are fluidly coupled to each other. This can be effected by directly connecting the treatment tool side ends of the first fluid lines or by appropriately connecting the treatment tool side ends of the first fluid lines using a fluid coupling element. In principle, this can also be realized in a specific environment for the medical treatment tool itself, where the medical treatment tool has an appropriate, preferably controllable fluid connection, for example, by activating the appropriate coupling function of the medical treatment tool or by the like.

[0017] For this purpose and also for intended use, the ophthalmic surgical system includes, for example, a treatment fluid source that can be arranged on the console side of an appropriate holder. The treatment fluid source may provide a treatment fluid that can be, for example, a rinsing fluid, in particular a rinsing liquid. The treatment fluid is conveyed from the console through a rinsing line to the treatment tool side end of the rinsing line. By the fluid that couples to the suction line at the treatment tool side end, the treatment fluid is then conveyed back to the console through the suction line, in which case this is supplied to a collection container. For example, the collection container can be a receptacle in which the treatment fluid conveyed to the console side by the suction line is stored.

[0018] According to the present invention, the console side is connected for fluid coupling the console to at least one medical treatment device or a further medical treatment device for at least one second fluid line for a treatment fluid. For example, this fluid line can also be a cleaning line or a suction line. Moreover, it is of course possible to provide a plurality of fluid lines which can be a cleaning line and / or a suction line as required. So as to be able to realize a desired rinsing treatment, it is also assumed that at least one second fluid line has a treatment device side end which is fluid coupled to at least one of the treatment device side ends of at least two first fluid lines. This also provides an option to convey the treatment fluid through at least one second fluid line. Accordingly, the console side pump device is designed to inject the treatment fluid into the second fluid line.

[0019] Parts or elements or units of the console into which the treatment fluid is injected are often arranged together with a separate replaceable part generally designed as a cartridge. As a result, the console itself does not need to be in direct contact with the treatment fluid. The cartridge is a replaceable part, usually designed as a single-use part, specifically a disposable part. This makes it possible to easily achieve good stability for the intended use. Thus, the cartridge includes, among other things, elements of the pump device that are in direct contact with the treatment fluid. For example, the pump device includes at least one fluid pump for each of cleaning and suction, and the pump is preferably entirely included in the cartridge. For example, the drive unit for the fluid pump may be provided on the console side, if possible, such that the cartridge includes only the elements in direct contact with the treatment fluid.

[0020] In addition, the cartridge may also include valve elements that can be used to control functions related to transporting the treatment fluid and guiding the treatment fluid into respective fluid lines. Also in this case, an appropriate valve drive can be provided on the console side. Thus, with a cartridge, it is possible to make available replacement parts or disposable parts that can function to ensure sterility with respect to the treatment fluid for each of the eye surgeries, i.e., an ophthalmic surgical system. Since only the treatment fluid needs to be fed through the cartridge, the treatment fluid does not need to flow through the console and does not need to come into contact with the console. Thus, by replacing the cartridge in the console after each use of each ophthalmic surgical system, it is easy to restore the sterility of the ophthalmic surgical system at any time. The cartridge may have a cartridge housing that can be formed from a suitable material, such as plastic or the like. The fluid pump may be designed in one piece with at least part of the cartridge housing.

[0021] In addition, when the connection of at least one second fluid line is detected, the treatment fluid is automatically injected into at least one second fluid line when connected to the console. As a result, the user of the ophthalmic surgical system does not need to perform any further act to flush or fill at least one second fluid line.

[0022] It is also proposed that the treatment fluid be injected into the fluid line, specifically for use with an ophthalmic surgical system, in one method step. Preferably, the treatment fluid is injected into the fluid line substantially simultaneously, such that the fluid line preferably contains only the treatment fluid at the end of this method step.

[0023] It is also proposed that the treatment fluid be injected into at least one second fluid line during the intended use of at least one medical treatment instrument. As a result, at least one second fluid line can be flushed during intended use, for example when performing surgery on the eye. This is particularly advantageous when a further medical treatment instrument fluidly connected to at least one second fluid line is used during eye surgery. In this way, the user of the ophthalmic surgical system does not have to substantially interrupt the treatment or surgery of the eye.

[0024] One development form proposes that at least one second fluid line is a second suction line for fluidly coupling a further medical treatment instrument. However, it is also possible to provide a second flushing line for the further medical treatment instrument. The considerations in this regard are correspondingly applicable. For example, the further medical treatment instrument can be a further handpiece. As a result of at least one second suction line, the further medical treatment instrument can be used on the same eye, for example, simultaneously with the first medical treatment instrument. In principle, there is no need to provide a second flushing line for the further medical treatment instrument in such cases. Particularly advantageously, at least one first suction line and at least one second suction line can be fluidly coupled to the same fluid pump of the pump device.

[0025] It is also proposed that the console activate the fluid lines individually using a valve device. As a result, each fluid line for each medical treatment instrument can be activated or deactivated as required. To achieve this goal, the valve device may include one or more suitable valves that can be controlled by a control device on the console side.

[0026] One development form proposes that for at least one of the fluid lines, the fluid resistance is confirmed with respect to the transport of the treatment fluid through this fluid line. For example, the fluid resistance can be measured using a sensor provided on the console side. To achieve this goal, for example, the functions of each fluid pump can also be considered. The functions of the ophthalmic surgical system can be monitored using the fluid resistance.

[0027] Furthermore, it is proposed that at least one operating parameter of the ophthalmic surgical system is set based on the confirmed fluid resistance. For example, the operating parameter can also relate to the pump function of at least one fluid pump of the pump device in the console, or the valve setting of the valve device and / or the like. However, it is also possible to generate warnings or operation notifications that can be output to the console side using, for example, a control device, within the range of, for example, a display for the user, an audio output for the user, and / or the like.

[0028] The medical treatment tool connected to each fluid line is determined based on at least the confirmed fluid resistance, and it is also proposed that at least one operating parameter of the determined medical treatment tool is specifically set based on the determined medical treatment tool. For example, it is possible to confirm whether the medical treatment tool is a vitreous cutter, an ultrasonic handpiece, or the like. Then, based on the confirmed or determined medical treatment tool, the function for the intended operation can be confirmed, and the corresponding operating parameter can be set on the console side. As a result, the adjustment cost for the user can be reduced and can even be completely avoided. Furthermore, since this can automatically recognize the medical treatment tool, the reliability can be improved.

[0029] The advantages and effects shown in the method according to the present invention are equally applicable to the ophthalmic surgical system, and vice versa. Specifically, the features of the method may thus be formulated as device features, and vice versa.

[0030] Further features of the present invention will become apparent from the claims, the drawings, and the description of the drawings. Features and combinations of features described in the above description, as well as features and combinations of features described in the description of the following drawings and / or shown only in the drawings, can be used not only in the respective specified combinations but also in other combinations without departing from the scope of the present invention. As a result, embodiments of the present invention that are not explicitly shown or described in the drawings but are apparent from separate combinations of features from the described embodiments and can be conceived should also be considered to be included and disclosed.

[0031] Further advantages and features of the present invention will be described with reference to the following figures.

Mode for Carrying Out the Invention

[0034] FIG. 1 shows a schematic diagram of an ophthalmic microsurgical system or an ophthalmic surgical system 35 for cataract surgery of a human eye 36. The figure according to FIG. 1 shows some components of the system 35 symbolically for a simplified explanation of the basic general functions of the system 35.

[0035] The ophthalmic surgical system 35 includes a console 53 as a device unit which may be, for example, a trolley or the like. Preferably, the operation unit 38 is arranged within or on the console 53. By way of example, this operation unit 38 may include a user interface, an input unit such as a keyboard or the like, and a display unit such as a monitor or a display. Further, a fluid system 39 including a pump device and a control device for controlling the pump and the connected components is preferably arranged within the console 53. The fluid system 39 includes a cleaning device with a cleaning line 40 and a suction device with a suction line 41. The cleaning device includes a container 42 for a rinsing liquid, for example a BSS solution, which is a cleaning fluid and is guided to the intraocular handpiece. The intraocular handpiece is the ophthalmic surgical handpiece 3. Specifically, this is a component of the ophthalmic surgical system 35. The suction line 41 is also connected to the ophthalmic surgical handpiece 3.

[0036] Moreover, the console 53 includes an ultrasonic unit 54. Specifically, the ultrasonic unit 54 is designed to excite the vibration of the piezoelectric element 43 within the ophthalmic surgical handpiece 3, and using it, the hollow needle 45 is excited to vibrate as a treatment needle of the ophthalmic surgical handpiece 3. The piezoelectric element 43 forms a piezoelectric-based drive unit 2. In this case, the ultrasonic unit 54 includes at least one control unit 1 including at least an AC voltage generator, a generator control unit, and a voltage sensor (not depicted here).

[0037] Furthermore, the console 53 specifically includes a control unit 55. The control unit 55 can also be designed to control the vitrectomy handpiece 46, which can specifically be a component of the ophthalmic surgery system 35. Preferably, the vitrectomy handpiece 46 is also connected to the fluid system 39, specifically by a suction line 47. Additionally, a further instrument control unit 48 can be provided, which controls a further surgical instrument 49 that is preferably available, for example, for diathermy. Moreover, the system 35 and specifically the console 53 may include further modules and control units, as well as a system represented symbolically by the unit 50. This includes further internal units and peripheral devices. Furthermore, the ophthalmic surgery system 35 preferably includes a foot control panel 51 that is connected to the console 53, specifically to the communication device and the control unit of the console 53.

[0038] Moreover, FIG. 1 schematically shows the natural lens 52 within the eye 36. This lens 52 can be removed by the ophthalmic surgery system 35, specifically by phacoemulsification.

[0039] In an alternative embodiment, the ophthalmic surgery system 35 can be made to include a tank 44 (FIG. 1) separate from the container 42. In such an embodiment, the cooling fluid provided for cooling the incision is provided separately from the cleaning device and separately from the container 42. The tank 44 can be arranged separately from the handpiece 3 and can be connected to the handpiece 3 via a line such as a pipe connection.

[0040] In a further embodiment, a separate tank 44 can be disposed within the handpiece 3. The separate tank 44 can be disposed within the handpiece 3 in a non-destructive and non-detachable manner, or in a non-destructive and detachable manner. Also, a first separate tank 44 can be disposed within the handpiece 3, and a further separate tank 56 can also be disposed outside the handpiece 3. This further separate tank 56 outside the handpiece 3 can be connected in a manner that guides fluid to the first separate tank 44 disposed within the handpiece 3.

[0041] Figures 2-4 show the console 53 in different views to more clearly depict the details. Figure 2 shows the console 53 in a front plan view, while Figure 3 shows the console 53 in a schematic side view, and Figure 4 shows the console 53 in a schematic perspective view.

[0042] It is clear from Figure 2 that the console includes a cartridge receiving region 10 within which a cartridge 11 is disposed. The cartridge receiving region 10 is defined within a lower region by a cartridge support 12 that holds the cartridge 11 vertically for gravity. On the sides and upper side of the cartridge receiving region 10, the console 53 includes maintaining a bracket 13 that engages over the cartridge 11 such that the cartridge 11 is inserted into the cartridge receiving region 10 as depicted in Figures 2-4 and thus attached at this position on the console 53.

[0043] In the present case, the cartridge 11 includes all elements of the console 53 that come into contact with the cleaning fluid and the suction fluid. The cartridge 11 is designed as a replaceable single-use part so that the sterility of the console 53 can be restored at low cost for subsequent treatments.

[0044] To achieve this goal, the cartridge 11 includes a pump device with a fluid pump, although these are not depicted in the figures. The cartridge 11 also includes a valve (not illustrated) of a valve device that can be used to control the conveyance of the treatment fluid, the cleaning fluid, and the suction fluid. To achieve this goal, the control and actuation element 14 is provided on the console side opposite the cartridge 11 within the cartridge receiving region 10 and contacts the cartridge 11 in a state where the cartridge 11 is inserted into the cartridge receiving region 10 in order to establish the intended functions using the cartridge 11 with respect to the fluid system 39.

[0045] In this case, the cartridge 11 can be manually inserted into the cartridge receiving region 10 and manually removed from the cartridge receiving region 10 again after use. To achieve this goal, the cartridge 11 includes a handle 15.

[0046] The cartridge 11 also includes a cleaning connector 16 and a suction connector 17 that are fluidly connected to the respective cleaning line 40 and suction line 41. The cleaning line 40 and the suction line 41 are connected to the ophthalmic surgical handpiece 3. Additionally, the cartridge 11 includes a cleaning connector 18 that is fluidly coupled to the container 42 via the cleaning line 20. The cleaning liquid is supplied from the container 42 to the cartridge 11 via the cleaning line 20. The cartridge 11 also includes a suction connector 19, and a collection container 21 is connected to the suction connector 19. The suction fluid sucked from the handpiece 3 via the suction line 41 or the suction liquid is guided to the collection container 21 via the suction connector 19 and collected or stored therein. The collection container 21 can be replaced.

[0047] The cartridge 11 includes at least a part of a pump device and a valve device, which are conveyed by the control and operating elements 14 on the console side in order to be able to appropriately convey the fluid flow through the fluid line. Thus, the cartridge 11 is used to supply the cleaning fluid supplied via the cleaning connector 18 of the cartridge 11 to the handpiece 3 via the cleaning connector 16 and the cleaning line 40. Conversely, the suction fluid received by the handpiece 3 is supplied to the cartridge 11 via the suction line 41 and the suction connector 17, and is supplied from the cartridge to the collection container 21 via the suction connector 19. The desired conveying effect is achieved by the pump device in conjunction with the valve device.

[0048] Figures 2 to 4 also depict that the cartridge 11 includes a second suction connector 22. As is apparent from FIG. 1, the second suction connector 22 serves to connect the second suction line 47 of the vitrectomy handpiece 46. During the intended use, the cartridge 11 is thus used to discharge the suction fluid not only via the handpiece 3 but also via the vitrectomy handpiece 46.

[0049] To operate the ophthalmic surgical system 35, the handpiece-side ends of the suction line 41 and the cleaning line 40, which form the first fluid line in this case, are fluidly coupled to each other. The pump device of the cartridge 11 is used to convey the cleaning fluid from the container 42 through the cleaning line 40 and the suction line 41 to the collection container 21 of the ophthalmic surgical system 35.

[0050] Furthermore, a second suction line 47 equipped with a vitrectomy handpiece 46 is connected on the console side to a cartridge 11 of a console 53 that is fluid-coupled to the vitrectomy handpiece 46. The vitrectomy handpiece-side end of the suction line 47 is fluid-coupled to the handpiece-side end of the cleaning line 40. The console-side pump device is used to convey the treatment fluid or the cleaning fluid through the second suction line 47 with appropriate control of the valve device. As a result, it is possible to rinse or pour all the fluid lines 40, 41, 47. This is preferably carried out in a single method step so that no further rinsing procedure needs to be performed for the purpose of performing the surgery.

[0051] In this case, the console 53 detects the connection of the second suction line 47 through the cartridge 11, specifically through the sensors provided therein. Thereafter, the cleaning fluid is automatically injected into the second suction line 47. Thus, the user no longer needs to perform a separation act.

[0052] Alternatively or additionally, during a surgery in which the handpiece 3 is already in use, if the vitrectomy handpiece 46 is operated only once, the cleaning fluid can be injected into the second suction line 47. To achieve this goal, individual control can be made possible using the valve device of the console 53 in combination with the cartridge 11.

[0053] Moreover, the respective fluid resistances regarding the conveyance of the cleaning fluid or the suction fluid are currently confirmed for the fluid lines 40, 41, 47 using sensors provided at least in part on the console side, specifically on the cartridge side. Based on this, the control unit 55 or the ultrasonic unit 54 determines the medical treatment tools to which they are connected, in this case the handpiece 3 or the vitrectomy handpiece 46. Based on this, the operation parameters for the handpieces 3, 46 are automatically set. Thus, the user of the ophthalmic surgical system 35 does not need to adjust any separate settings in this manner. As a result, the certainty and safety can be further improved.

[0054] Specifically, each of the handpieces 3, 46 can be defined in this way. Of course, the definition of the handpiece through RFID or the like can also be provided additionally or alternatively. The necessary operating parameters can be stored retrievably in the storage device of the console 53. However, the console 53 can also retrieve the appropriate operating parameters for each defined handpiece 3, 46 via the communication link to the central database and adjust the appropriate settings.

[0055] Thus, the present invention allows the handpiece to be preferably rinsed or flushed before the surgical operation. Moreover, of course, during the surgical operation, the newly added handpieces can also be individually rinsed or flushed. However, since the fluid supply to the already operable handpieces may not be maintained during rinsing or priming, priming should be fully considered in the fact that it may interrupt the surgical operation in a certain environment.

[0056] Preferably, rinsing or priming also includes the cartridge 11 of the console 53.

[0057] Moreover, when a plurality of handpieces are connected to the console 53 or the cartridge 11, the connected handpieces can of course be continuously rinsed or flushed through appropriate control without the user having to perform further actions.

[0058] In this case, the operating parameters may be in the range of, for example, about 19 gauge to about 27 gauge, that is, may have an inner diameter range of about 1.1 millimeters to about 0.4 millimeters, for example, may refer to the fluid diameter. The fluid resistance is preferably stored in the form of data in a table. The inner diameters of the fluid lines 40, 41, 47 can be calculated based on the confirmed fluid resistance, and the operating parameters can be appropriately set accordingly.

[0059] Overall, the present invention makes it possible to further improve the use of the ophthalmic surgical system.

[0060] The exemplary embodiments are only useful for explaining the present invention and do not limit the present invention.
