From the foregoing, the laparoscopic high pressure drug nebulizer may endoluminally nebulize chemotherapeutic drugs, allowing the nebulized aerosol to penetrate all luminal surfaces. The current laparoscope high-pressure medicine atomizer is usually in a manual driving mode, the medicine spray head is a linear spray head, the space achieved in a cavity is limited, the spraying direction is unique, and the spraying angle is difficult to adjust so as to accurately spray medicine.

At least one embodiment of the present application provides a medication sprayer including a spray head, a rotatable member, a connecting conduit having opposite first and second ends, the spray head being connected to the first end by the rotatable member, and a drive device connected to the second end and configured to control rotation of the rotatable member to drive the spray head.

The spray head of the medicine sprayer provided by the embodiment of the application can rotate through the rotatable component, so that the medicine spraying direction can be changed to accurately spray medicine, and the medicine sprayer can adopt the driving device to control the spraying direction of the spray head, can be applied to a surgical robot, and realizes systematic operation. For example, the drug sprayer can be used as a laparoscope high-pressure drug sprayer and can be matched with a surgical robot to realize various treatment scenes such as endoscopic surgery.

The drug sprayer provided by the embodiment of the application is described in detail below through several specific examples.

At least one embodiment of the present application provides a medicine sprayer, and fig. 1 shows a schematic structural view of the medicine sprayer, and as shown in fig. 1, the medicine sprayer includes a spray head 10, a rotatable member 20, a connection pipe 30, a driving device 40, and the like.

The connecting conduit 30 has opposite first and second ends 31 and 32, the sprinkler head 10 being connected to the first end 31 by the rotatable member 20 such that the sprinkler head 10 can be rotated about the rotatable member 20 relative to the first end 31 to change the spray direction of the sprinkler head 10; the driving device 40 is connected to the second end 32 and configured to control the rotatable member 20 to rotate so as to drive the spray head 10 to rotate, thereby controlling the spraying direction of the spray head 10.

For example, fig. 2 shows a schematic view of a structure of a spray head and a rotatable member in a drug sprayer. In some embodiments, as shown in fig. 2, the drug sprayer further comprises at least one connection line 50, for example comprising a plurality of connection lines 50, the connection lines 50 being connected from the drive device 40 to the rotatable member 20 through the connection conduit 30, wherein the drive device 40 is configured to drive the connection lines 50 to extend or retract (i.e. to increase or decrease the length of the connection lines 50 extending out of the drive device 40) to control the rotation of the rotatable member 20, for example to control the direction of rotation and the angle of rotation of the rotatable member 20.

For example, in some embodiments, the rotatable member 20 may include at least two rotatable portions that are rotatable relative to one another, where the driving device 40 is configured to control the at least two rotatable portions to rotate relative to one another to rotate the spray head 10 to control the spray direction of the spray head 10.

For example, in some embodiments, as shown in fig. 2, the rotatable member 20 includes three rotating parts, that is, a first rotating part 21, a second rotating part 22, and a third rotating part 23, where the first rotating part 21 is connected to the spray head 10, the second rotating part 22 is connected to the first end 31 of the connecting conduit 30, the third rotating part 23 is rotatably connected between the first rotating part 21 and the second rotating part 22, the third rotating part 23 and the first rotating part 21 can rotate relatively and have a first rotation axis, that is, the third rotating part 23 and the first rotating part 21 can rotate relatively along the first rotation axis, and the direction of the first rotation axis is the R1 direction in fig. 2. The third rotating portion 23 and the second rotating portion 22 can rotate relatively and have a second rotation axis, that is, the third rotating portion 23 and the second rotating portion 22 can rotate relatively along the second rotation axis, and the direction of the second rotation axis is the R2 direction in fig. 2. The first rotation axis is different from the second rotation axis in direction so that the head 10 can be rotated in at least four directions by the rotatable member 20.

For example, the rotation of the third rotation portion 23 and the first rotation portion 21 with respect to the first rotation axis and the rotation of the third rotation portion 23 and the second rotation portion 22 with respect to the second rotation axis may be performed simultaneously or separately; therefore, the spraying position and the spraying angle of the spray head 10 can be adjusted, so that the spray head 10 can reach more positions and more rotatable angles, and the omnibearing accurate spraying is realized.

For example, in some embodiments, the first axis of rotation is perpendicular to the direction of the second axis of rotation to provide a more comprehensive spray direction of the spray head 10.

For example, in other embodiments, the rotatable member 20 may include only two rotatable portions that are rotatable relative to one another, and in this case, the two rotatable portions may be rotatable in opposite directions or in more directions.

For example, fig. 4A shows a schematic structural diagram of another medicine sprayer according to at least one embodiment of the present application, in the medicine sprayer shown in fig. 4A, the rotatable member 20 includes a first rotatable portion 21 and a second rotatable portion 22, the first rotatable portion 21 is connected to the nozzle 10, the second rotatable portion 22 is connected to the first end 31 of the connecting conduit 30, and the first rotatable portion 21 and the second rotatable portion 22 are controlled to rotate relatively in multiple directions.

Alternatively, in other embodiments, the rotatable member 20 may include more than three rotating portions, where each two adjacent rotating portions may rotate relative to each other, and the directions of the relative rotation between each two adjacent rotating portions may be different, so as to increase the diversification of the spray head steering.

For example, as shown in fig. 2, the medicine sprayer includes a plurality of connection lines 50 (four connection lines 50 are shown in the drawing), and the plurality of connection lines 50 are respectively connected to different positions of the rotatable member 20, so that the plurality of connection lines 50 are respectively extended or retracted in different manners by the driving means 40, thereby achieving the purpose of controlling the rotatable member 20 to rotate in different directions.

For example, in some embodiments, as shown in FIG. 2, the connection line 50 may also be connected to the sprinkler head 10 through the rotatable member 20 and secured to the sprinkler head 10. Thus, the connection wire 50 connects the driving means 40, the connection pipe 30, the rotatable member 20 and the spray head 10 together in order, whereby the stability of the overall structure of the medicine sprayer can be enhanced.

For example, in some embodiments, the connecting conduit 30 may be a hollow conduit through which the connecting wire 50 may pass directly; alternatively, in other embodiments, the interior of the connecting conduit 30 may also have slots or through holes for the connecting wires 50 to extend to define the path of extension of the plurality of connecting wires 50. For example, the inner wall of the rotatable member 20 has a through hole V (refer to fig. 3) through which the connection wire 50 extends, so that the engagement between the connection wire 50 and the rotatable member 20 is more stable.

For example, in some embodiments, as shown in fig. 2, the spray head 10 includes a spray head base 12 and a spray head body 11 provided on the spray head base 12, and at least one spray hole O is provided on the spray head body 11 so that the medicine is sprayed through the spray hole O. For example, the head 10 is provided with the above-described injection hole O at the tip of the head main body 11. For example, the head main body 11 is disposed at a central position of the head base 12, and the plurality of connection lines 50 are connected to a plurality of positions 13 of an edge of the head base 12, respectively, the plurality of positions 13 surrounding the head main body 11.

For example, in some embodiments, as shown in fig. 2, the showerhead base 12 has first through holes at the plurality of locations 13, respectively, the plurality of connection lines 50 pass through the first through holes at the plurality of locations 13, respectively, the plurality of connection lines 50 have an expansion portion 55 (refer to fig. 3) at an end portion of the showerhead body 11 side, and the expansion portion 55 has a size larger than an aperture of the first through holes, so that the plurality of connection lines 50 are fixed at the plurality of locations 13 by the expansion portion 55.

For example, fig. 3 shows a schematic cross-sectional structure of a spray head and a rotatable member of a medicine sprayer, and as shown in fig. 3, the expansion portions 55 of the plurality of connection lines 50 have a width larger than that of the main body portion of the connection line 50 and larger than the aperture of the first through hole, so as to be caught on the spray head base 12 at a plurality of positions 13. For example, in some embodiments, as shown in FIG. 3, the edge of the spray head base 12 has a slot that receives the expansion 55 such that the expansion 55 is stably secured in the slot and thus on the spray head base 12.

For example, in some embodiments, as shown in fig. 2, the spray head base 12 and the first rotating portion 21 may be snapped together. For example, the first rotating portion 21 has a first engaging groove 21A at a portion where the nozzle base 12 is connected to the nozzle base 12, and a first engaging protrusion 12A at a portion where the nozzle base 12 is connected to the first rotating portion 21, and the first engaging protrusion 12A may be engaged into the first engaging groove 21A to firmly connect the first rotating portion 21 to the nozzle base 12. Similarly, the second rotating portion 22 and the connecting duct 30 may also be clamped together. For example, the second rotating portion 22 has a second clamping groove 22A at a portion connected to the connecting conduit 30, and the connecting conduit 30 has a second clamping protrusion 30A at a portion connected to the second rotating portion 22, and the second clamping protrusion 30A can be clamped into the second clamping groove 22A, so that the second rotating portion 22 is firmly connected to the connecting conduit 30.

For example, in other embodiments, the rotatable member 20 may be other forms, such as a one-piece rotatable member. For example, fig. 4B shows a schematic view of another medication sprayer according to at least one embodiment of the application, in which the rotatable member 20 has an arcuate guide 20A at least on the side of the spray head 10 or on the side of the connection conduit 30, so that the spray head 10 can be rotated relative to the first end of the connection conduit 30 by the rotatable member 20 when the drive means extends or retracts the connection line 50. At this time, as shown in fig. 4B, the section of the rotatable member 20 may be circular, and in other embodiments, the section of the rotatable member 20 may be racetrack-shaped or the like for facilitating rotation.

For example, in the embodiment of fig. 4B, the plurality of connection lines 50 may include a first connection line 51 and a second connection line 52 disposed at intervals, for example, disposed opposite to each other, and in this case, the driving device 40 may be configured to: the first connection line 51 is driven to extend and the second connection line 52 is driven to retract to control rotation of the head 10 in a first direction (lower side in fig. 4B), or the second connection line 52 is driven to extend and the first connection line 51 is driven to retract to control rotation of the head 10 in a second direction (upper side in fig. 4B), the first and second directions being opposite to each other.

For example, as shown in fig. 4B, the connection line 50 may further include a third connection line 53 and a fourth connection line 54 (which are blocked in the figure) disposed at intervals, for example, oppositely disposed, and in this case, the driving device 40 is configured to: the third connection line 53 is driven to extend and the fourth connection line 54 is driven to retract to control rotation of the head 10 in a third direction (a direction perpendicular to the paper surface in fig. 4B), or the fourth connection line 54 is driven to extend and the third connection line 53 is driven to retract to control rotation of the head 10 in a fourth direction (a direction perpendicular to the paper surface in fig. 4B), the third direction and the fourth direction being opposite, and the third direction, the fourth direction, the first direction and the second direction being different. Thus, the sprinkler head 10 can be rotated in at least four directions.

For example, the first connecting line 51, the second connecting line 52, the third connecting line 53 and the fourth connecting line 54 are uniformly disposed around the rotatable member 20, and can limit the rotatable member 20. For example, in some embodiments, the nozzle base 12 of the nozzle 10 and the first end 31 of the connecting conduit 30 may also have corresponding rotational grooves (not shown) to receive and cooperate with the arcuate guide 20A for rotational operation.

For example, in the embodiment of fig. 4B, the drug sprayer may also include more connection lines to increase the rotational freedom of the spray head, which is not described in detail herein.

For example, in other embodiments, the rotatable member 20 may take other forms, as shown in fig. 5, the rotatable member 20 may be a compression rotatable member, and similarly, the plurality of connection lines 50 may include a first connection line 51 and a second connection line 52 disposed at intervals, for example, opposite to each other, where the driving device 40 is configured to: the first connection line 51 is driven to extend and the second connection line 52 is driven to retract to control rotation of the spray head 10 in a first direction (lower side in fig. 4B), at which time the lower side of the compressive rotatable member is compressed, or the second connection line 52 is driven to extend and the first connection line 51 is driven to retract to control rotation of the spray head 10 in a second direction (upper side in fig. 4B), at which time the upper side of the compressive rotatable member is compressed, the above-described first and second directions being opposite.

For example, in the embodiment of fig. 5, the plurality of connection lines 50 may further include a third connection line 53 and a fourth connection line 54 (which are blocked in the figure) disposed at intervals, for example, oppositely disposed, and the driving device 40 is configured to: the third link 53 is driven to extend and the fourth link 54 is driven to retract to control rotation of the spray head 10 in a third direction (direction perpendicular to the paper surface in fig. 4B), at which time the side of the compressive rotatable member perpendicular to the paper surface is compressed, or the fourth link 54 is driven to extend and the third link 53 is driven to retract to control rotation of the spray head 10 in a fourth direction (direction perpendicular to the paper surface in fig. 4B), at which time the side of the compressive rotatable member perpendicular to the paper surface is compressed, the third direction being opposite to the fourth direction, and the third direction, the fourth direction, the first direction, and the second direction being different. Thereby, the spray head 10 can also be rotated at least in four directions.

Similarly, in the embodiment of fig. 5, the medication sprayer may also include more connection lines 50 to increase the rotational freedom of the spray head.

For example, in the embodiment of fig. 2 and 3, the rotatable member 20 includes a plurality of rotating portions, and the plurality of connecting lines 50 have different arrangements and driving patterns from the above-described embodiments. For example, fig. 6 shows a schematic structural view of the plurality of connection lines 50 and the rotatable member 20, and as shown in fig. 6, the plurality of connection lines 50 include a first connection line 51, a second connection line 52, a third connection line 53, and a fourth connection line 54, and the first connection line 51, the second connection line 52, the third connection line 53, and the fourth connection line 54 are sequentially disposed along the circumferential direction of the head 10, and in this case, the driving device may be configured to: simultaneously driving the first connection line 51 and the fourth connection line 54 to extend and simultaneously driving the second connection line 52 and the third connection line 53 to retract to control the rotation of the head 10 in the first direction (right direction in fig. 6), or simultaneously driving the second connection line 52 and the third connection line 53 to extend and simultaneously driving the first connection line 51 and the fourth connection line 54 to retract to control the rotation of the head 10 in the second direction (left direction in fig. 6), at which time the relative rotation occurs between the first rotation portion 21 and the third rotation portion 23; alternatively, the driving device is configured to: the first and second connection lines 51 and 52 are simultaneously driven to extend and the third and fourth connection lines 53 and 54 are simultaneously driven to retract to control the rotation of the head 10 in the third direction (the lower direction in fig. 6), or the third and fourth connection lines 53 and 54 are simultaneously driven to extend and the first and second connection lines 51 and 52 are simultaneously driven to retract to control the rotation of the head 10 in the fourth direction (the upper direction in fig. 6), at which time the relative rotation occurs between the second and third rotation portions 22 and 23.

The first direction and the second direction are opposite, the third direction and the fourth direction are opposite, the third direction, the fourth direction, the first direction and the second direction are different, and the relative rotation between the first rotation part 21 and the third rotation part 23 and the relative rotation between the second rotation part 22 and the third rotation part 23 can be performed simultaneously or respectively, so that the spray head 10 can rotate along a plurality of different directions, and the movement of the position can also occur, so as to achieve a plurality of positions, and realize the omnidirectional accurate spray.

For example, in the embodiment of fig. 2 and 3, the rotatable member 20 includes three rotating portions, and fig. 7 and 8 show schematic cross-sectional views of the three rotating portions in different directions, respectively. As shown in fig. 7, one of the first rotating portion 21 and the third rotating portion 23 (shown as the first rotating portion 21 in fig. 7) has two first engaging projections 61 (one of which is shown in fig. 7) disposed opposite to each other, the other of the first rotating portion 21 and the third rotating portion 23 (shown as the third rotating portion 23 in fig. 7) has two first engaging grooves 71 (one of which is shown in fig. 7) disposed opposite to each other, two first arc-shaped groove portions 81 disposed opposite to each other are provided between the two first engaging projections 61 disposed opposite to each other, two second arc-shaped groove portions 82 disposed opposite to each other are provided between the two first engaging grooves 71 disposed opposite to each other, and the first engaging projections 61 and the first engaging grooves 71 are rotationally engaged, that is, the first engaging projections 61 can be rotated within a space defined by the first engaging grooves 71 to adjust an opening angle between the first arc-shaped groove portions 81 and the second arc-shaped groove portions 82 disposed opposite to each other, so that the relative rotation of the third rotating portion 23 and the first rotating portion 21 is achieved with respect to the axis of rotation of the first rotating portion 21.

Similarly, as shown in fig. 8, one of the second rotating portion 22 and the third rotating portion 23 (shown as the second rotating portion 22 in fig. 8) has two second engaging projections 62 disposed opposite to each other, the other of the second rotating portion 22 and the third rotating portion 23 (shown as the third rotating portion 23 in fig. 8) has two second engaging recesses 72 disposed opposite to each other, two third arcuate recess portions 83 disposed opposite to each other are provided between the two second engaging projections 62 disposed opposite to each other, two fourth arcuate recess portions 84 disposed opposite to each other are provided between the two second engaging recesses 72 disposed opposite to each other, and the second engaging projections 62 and the second engaging recesses 72 are rotatably engaged with each other, that is, the second engaging projections 62 are rotatable within a space defined by the second engaging recesses 72 to adjust an opening angle between the third arcuate recess portions 83 and the fourth arcuate recess portions 84 disposed opposite to each other, thereby achieving relative rotation of the third rotating portion 23 and the second rotating portion 22 with respect to the second rotation axis.

For example, as shown in fig. 7 and 8, the third rotating portion 23 has two first engaging grooves 71 oppositely disposed on the side close to the first rotating portion 21, the third rotating portion 23 has two second engaging grooves 72 oppositely disposed on the side close to the second rotating portion 22, the first rotating portion 21 has two first engaging protrusions 61 oppositely disposed on the side close to the third rotating portion 23, and the second rotating portion 22 has two second engaging protrusions 62 oppositely disposed on the side close to the third rotating portion 23. Thus, the first engaging groove 71 and the second engaging groove 72 are provided on the third rotating portion 23 located in the middle, and the first engaging protrusion 61 and the second engaging protrusion 62 are provided on the first rotating portion 21 and the second rotating portion 22 located on both sides, respectively, which facilitates the relative rotation between the first rotating portion 21 and the third rotating portion 23 and the relative rotation between the second rotating portion 22 and the third rotating portion 23 to be performed simultaneously.

For example, as shown in fig. 7 and 8, the planar shapes of the first and second fitting recesses 71 and 72 may be rectangular, in other embodiments, may be arc-shaped or other suitable shapes, and the first and second fitting protrusions 61 and 62 may be arc-shaped with protrusions, in other embodiments, may be semicircular or other suitable shapes, and embodiments of the present application are not limited thereto in particular.

For example, as shown in fig. 6 to 8, the first connection line 51, the second connection line 52, the third connection line 53, and the fourth connection line 54 are connected to the head 10 from the driving device 40 through the connection duct 30, the second rotation portion 22, the third rotation portion 23, and the first rotation portion 21 in this order, and each of the first arc groove portion 81, the second arc groove portion 82, the third arc groove portion 83, and the fourth arc groove portion 84 is penetrated by two of the first connection line 51, the second connection line 52, the third connection line 53, and the fourth connection line 54.

For example, as shown in fig. 6 to 8, each adjacent two of the first connection line 51, the second connection line 52, the third connection line 53, and the fourth connection line 54 has one first fitting protrusion 61 and one first fitting groove 71 or one second fitting protrusion 62 and one second fitting groove 72 that are fitted to each other.

The above-described connection structure is more stable, so that the process of driving the rotation of the spray head 10 by the driving device 40 is more accurate and stable.

For example, in other embodiments, as shown in fig. 9, the first, second, third, and fourth connection lines 51, 52, 53, and 54 may be connected only to the rotatable member 20. For example, as shown in fig. 9, a first connection line 51 and a second connection line 52 (reference numeral 52 in fig. 9 indicates that the second connection line is located on the opposite side of the first connection line 51, the second connection line 52 is not shown in the drawing for structural angle reasons) are connected and fixed to the third rotation portion 23 from the driving device 40 through the connection duct 30, the second rotation portion 22 in order. For example, the ends of the first and second connection lines 51 and 52 have expansion portions, respectively, and the third rotation portion 23 has a groove therein to accommodate the expansion portions, so that the first and second connection lines 51 and 52 may be fixed to the third rotation portion 23 by the expansion portions to control the relative rotation between the second and third rotation portions 22 and 23, and at this time, the driving device 40 may be configured to: the first connection line 51 is driven to extend and the second connection line 52 is driven to retract to control the rotation of the head 10 in a first direction (lower side in fig. 9), or the second connection line 52 is driven to extend and the first connection line 51 is driven to retract to control the rotation of the head 10 in a second direction (upper side in fig. 9), the first and second directions being opposite to each other.

Similarly, as shown in fig. 9, the third connecting wire 53 and the fourth connecting wire 54 (the reference numeral 54 in fig. 9 indicates that the fourth connecting wire is located on the opposite side of the third connecting wire 53, the fourth connecting wire 54 is not shown in the drawing for structural reasons) are connected from the driving device 40 sequentially through the connecting duct 30, the third rotating portion 23 and fixed to the first rotating portion 21, for example, the ends of the third connecting wire 53 and the fourth connecting wire 54 have expansion portions, respectively, inside the first rotating portion 21 have grooves accommodating the expansion portions, so that the third connecting wire 53 and the fourth connecting wire 54 can be fixed to the first rotating portion 21 by the expansion portions, thereby controlling the relative rotation between the first rotating portion 21 and the third rotating portion 23, at which time the driving device 40 is configured to: the third connection line 53 is driven to extend and the fourth connection line 54 is driven to retract to control the rotation of the head 10 in a third direction (left side in fig. 9), or the fourth connection line 54 is driven to extend and the third connection line 53 is driven to retract to control the rotation of the head 10 in a fourth direction (right side in fig. 4B), which are opposite to each other, and the third direction, the fourth direction, the first direction, and the second direction are different. Thereby increasing the rotational freedom of the sprinkler head 10.

For example, in other embodiments, the rotatable member 20 may be a hingeable member, for example, compared to the embodiment of fig. 2 and 3, the difference may be that the connection between the first rotating portion 21 and the third rotating portion 23 and the connection between the second rotating portion 22 and the third rotating portion 23 are the hinge by the hinge shaft, and in this case, the portions where the first rotating portion 21 and the third rotating portion 23 are connected have hinge holes through which the hinge shaft passes, respectively, so that the first rotating portion 21 and the third rotating portion 23 can rotate with respect to the hinge shaft; similarly, the portions where the second rotating portion 22 and the third rotating portion 23 are connected have hinge holes through which the hinge shafts pass, respectively, so that the second rotating portion 22 and the third rotating portion 23 can rotate with respect to the hinge shafts.

Of course, in other embodiments, the rotatable member 20 may take other possible forms, and will not be described in detail herein.

For example, fig. 10A and 10B show schematic views of the spray head of the medicine sprayer according to the embodiments of fig. 2 and 9, respectively, rotated in different directions, fig. 10A shows schematic views of the relative rotation between the second rotation portion 22 and the third rotation portion 23, and fig. 10B shows schematic views of the relative rotation between the first rotation portion 21 and the third rotation portion 23. The relative rotation between the second rotation part 22 and the third rotation part 23 and the relative rotation between the first rotation part 21 and the third rotation part 23 can be performed simultaneously or separately, thereby increasing the spraying direction and the spraying position of the spray head 10, enabling the spraying direction and the spraying position of the spray head to be diversified, and realizing the effect of precisely spraying the medicine.

For example, in an embodiment of the present application, the connection wire 50 may include a metal wire, and the material of the metal wire may include a tungsten alloy, so that the connection wire 50 forms an alloy tungsten wire. The alloy tungsten wire has better flexibility, tensile strength, abrasion resistance, heat resistance, oxidation resistance and fatigue resistance, and is safer and more reliable to use as the connecting wire 50. For example, the connecting wire 50 may have a diameter of 0.4mm to 0.6mm, such as 0.5mm, to meet operating requirements.

For example, the connecting conduit 30 may comprise a metal tube, and the material of the metal tube may comprise stainless steel, such as 304 stainless steel. The 304 stainless steel can meet the use requirement of the connecting conduit 30 and has low cost. For example, the outer diameter of the connecting conduit 30 may be 8.0mm-9.0mm, such as 8.4mm or 8.5mm, and the inner diameter of the connecting conduit 30 may be 7.0mm-8.0mm, such as 7.4mm or 7.5mm.

For example, the material of the sprinkler head 10 may include an alloy material, such as martensitic precipitation-hardenable stainless steel (17-4 PH). Because the spray head 10 is generally manufactured by adopting a powder metallurgy manufacturing process, 17-4PH can meet the requirements of the use environment and the hardness design, and the cost and the manufacturing cost of the 17-4PH material are low.

For example, fig. 11 shows a schematic structural diagram of a driving device of a medication sprayer according to at least one embodiment of the present application, and as shown in fig. 11, in some embodiments, the driving device 40 includes a plurality of driving shafts, at least part of which is configured to be connected to a plurality of connection lines 50 for driving the plurality of connection lines 50.

Thus, each drive shaft is used to drive one connecting wire 50.

For example, in the above embodiment, the driving device 40 may further include a first guide roller, a second guide roller, a third guide roller, and a fourth guide roller (refer to the first guide roller 412 in fig. 12), the first connecting wire 51 is connected through the first guide roller 412 and wound around the first winch 411, the second connecting wire 52 is connected through the second guide roller and wound around the second winch, the third connecting wire 53 is connected through the third guide roller and wound around the third winch, and the fourth connecting wire 54 is connected through the fourth guide roller and wound around the fourth winch. The first guide pulley 412, the second guide pulley, the third guide pulley and the fourth guide pulley are located, for example, on a side of the driving device 40 near the connection duct 30 for introducing and guiding the plurality of connection wires 50 into the driving device 40.

For example, in other embodiments, two connecting lines 50 may be connected to each drive shaft, thereby simplifying the drive control of the drive device.

For example, fig. 12 to 14 show schematic diagrams of a connection wire wound on a capstan by a guide wheel in a medication sprayer according to at least one embodiment of the present application. As shown in fig. 11 to 14, in this embodiment, the driving device 40 includes a first driving shaft 41 and a first capstan 411 connected to the first driving shaft 41, and a second driving shaft 42 and a second capstan 421 connected to the second driving shaft 42, at which time, the first connecting wire 51 and the third connecting wire 53 may be wound around the first capstan 411 in opposition, as shown in fig. 13 and 14, such that when the first driving shaft 41 rotates, one of the first connecting wire 51 and the third connecting wire 53 is extended, and the other is retracted, for example, in fig. 14, when the driving shaft drives the capstan to rotate clockwise, the first connecting wire 51 is retracted, the third connecting wire 53 is extended, and when the driving shaft drives the capstan to rotate counterclockwise, the first connecting wire 51 is extended, and the third connecting wire 53 is retracted. Similarly, the second connection wire 52 and the fourth connection wire 54 are wound around the second capstan 421 in opposition such that when the second drive shaft 42 rotates, one of the second connection wire 52 and the fourth connection wire 54 is extended and the other is retracted.

For example, the driving device 40 at this time may further include a first guide wheel 412 and a second guide wheel 422, where the first guide wheel includes at least two first guide grooves 412A and 412B, and as shown in fig. 13, the first connection wire 51 and the third connection wire 53 are connected through one first guide groove and wound around the first capstan 411, respectively; similarly, the second guide wheel 422 includes at least two second guide grooves (not shown), and the second connection wire 52 and the fourth connection wire 54 are connected through one second guide groove, respectively, and wound around the second capstan 421. Thus, the medicine sprayer can realize the driving action on the spray head through two driving shafts.

For example, in some embodiments, as shown in fig. 14, the end of each connection wire 50 wound on the capstan has a protrusion 50A, and accordingly, the winding shaft of the capstan has a groove 41A, and the protrusion 50A of the connection wire 50 may be caught in the groove 41A to fix the end of the connection wire 50 to the winding shaft of the capstan.

For example, in fig. 11, the first driving shaft 41 and the second driving shaft 42 may be used to perform the driving function of the connection line 50, and the third driving shaft 43 and the fourth driving shaft 44 may be used to control the spray head 10 to perform the spraying function of the aerosol, etc., and the specific manner of spraying the aerosol by the spray head 10 is not limited in the embodiment of the present application.

For example, corresponding to the embodiment of fig. 4A, 4B and 5, the driving device 40 may include a first driving shaft and a first capstan connected to the first driving shaft, and at this time, the first connection wire 51 and the second connection wire 52 may be wound around the first capstan in opposition such that one of the first connection wire and the second connection wire is extended and the other is retracted when the first driving shaft is rotated. For example, the driving device 40 may further include a first guide wheel, where the first guide wheel includes at least two first guide grooves, and the first connection wire 51 and the second connection wire 52 are connected through one first guide groove and wound around the first winch, respectively. It is thereby achieved that the first connection line 51 and the second connection line 52 are driven simultaneously by one drive shaft and the rotatable member 20 is driven to rotate in a certain direction.

For example, corresponding to the embodiment of fig. 4A, 4B and 5, the driving device 40 may further include a second driving shaft and a second capstan connected to the second driving shaft, and at this time, the third connecting wire 53 and the fourth connecting wire 54 may be wound around the second capstan in opposition, such that one of the third connecting wire 53 and the fourth connecting wire 54 is extended and the other is retracted when the second driving shaft rotates. For example, the driving device 40 may further include a second guide wheel, where the second guide wheel includes at least two second guide grooves, and the third connecting wire 53 and the fourth connecting wire 54 are connected through one second guide groove and wound around the second winch, respectively. It is thereby achieved that the third connection line 53 and the fourth connection line 54 are driven simultaneously by one drive shaft and the rotatable member 20 is driven to rotate in a certain direction.

The medicine sprayer provided by the embodiment of the application can control the spraying direction and the spraying position of the spray head 10 through the driving device 40 to realize the effect of medicine in-situ spraying, and can be used as a laparoscope high-pressure medicine sprayer to be matched with a surgical robot to realize systematic operation. When performing an operation, the medicine sprayer can be controlled by an operation robot, and the spray head 10 can rotate in the cavity, so that the spraying direction and the spraying position of the spray head 10 are changed, dead-angle-free positioning is realized, and medicine spraying is accurate. For example, by combining the drug sprayer with the surgical robot, an endoscopic surgical system can be realized, the operability of the surgery is enhanced, the drug utilization rate is improved, a low-dose high-curative effect is realized, and the postoperative wound is smaller and bleeding is less for a patient.

For example, as described above, the driving means includes a plurality of driving shafts, and in this case, the operation arm may be configured to control the plurality of driving shafts of the driving means to control the ejection head of the medicine sprayer, for example, whether the medicine sprayer is performing an operation of spraying medicine or not.

For example, fig. 15 illustrates a surgical robot provided in accordance with at least one embodiment of the present application, which may be combined with a drug sprayer, for example, to implement an endoscopic surgical system.

For example, as shown in fig. 15, the surgical robot 100 includes a plurality of surgical operation arms, shown as four surgical operation arms 101/102/103/104, and a medicine sprayer may be coupled to at least one of the four surgical operation arms 101/102/103/104 and a driving means of the medicine sprayer is controlled by the surgical operation arms. For example, when the driving shaft in the driving device receives the driving force output by the operation arm of the surgical robot or other driving force which can be controlled by operation, the capstan is driven to move, and the capstan rotates to change the state of the connecting wire, so that the rotatable member in the medicine sprayer bends from the neutral cubic position, as shown in fig. 10A and 10B, thereby controlling the spray head 10 to change state to reach the target position, and then accurately spraying the medicine.
