Description

Technical Field

[0001] The invention relates to the technical field of surgical lamps, in particular to a surgical lamp. Background Art

[0002] Surgical lights, also known as shadowless lights, are medical equipment specifically used in operating rooms. Their main function is to provide uniform, bright, high-quality light during surgery, helping doctors to clearly observe the operating area and ensure the safety and precision of the surgery. The double-headed shadowless lamp, also known as the mother-and-child lamp, can irradiate light onto the operating table from different angles through the layout of two lamp heads, thereby more effectively reducing or eliminating shadows in the operating area.

[0003] In spinal surgery, doctors use high-frequency electric knives to precisely cut soft tissues and achieve rapid hemostasis through electrocoagulation, thereby reducing the amount of bleeding and the need for blood transfusion during surgery. However, a large amount of smoke is generated when cutting and vaporizing tissue proteins and fats. The smoke contains a large amount of water vapor, cell fragments and harmful chemical components, such as CO, phenols, hydrocarbons, acrylonitrile, etc. When the surgical smoke concentration is high and directly contacts the surface of the surgical headlamp, the particulate matter in the smoke will adhere to the lampshade or lens to form a thin layer of smoke. Due to the obstruction of the smoke, the light emitted by the lampshade will be scattered and absorbed when passing through the smoke and the surface of the lampshade, resulting in a decrease in the light intensity reaching the surgical area. The formation of shadows will limit the clarity of the surgical field, increase the difficulty and risk of surgical operations, and cause medical staff to adjust the position of the lampshade or increase the lighting intensity according to actual conditions to overcome this effect, affecting surgical efficiency and increasing surgical time. For this reason, we propose a surgical lamp. Summary of the invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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.

[0032] Embodiment 1

[0033] See also Figures 1 to 9The present invention provides a technical solution: a surgical lamp, comprising a fixing seat 1 and a shadowless lamp 2, wherein two shadowless lamps 2 are provided and located outside the fixing seat 1; further comprising a headlamp 3, wherein a light sensor 4 is installed on the surface of the headlamp 3, and the light intensity of the operating area is monitored by the light sensor 4; a connecting mechanism 5, wherein the connecting mechanism 5 is respectively connected to the shadowless lamp 2 and the fixing seat 1, and the two shadowless lamps 2 adjust the irradiation angle through the connecting mechanism 5; an adjusting mechanism 6, wherein the adjusting mechanism 6 is connected to the headlamp 3, and the adjusting mechanism 6 adjusts the overlapping range of the two shadowless lamps 2 according to the lighting intensity of the headlamp 3; a processing mechanism 7, wherein the processing mechanism 7 is located outside the shadowless lamp 2, and the processing mechanism 7 adjusts the cleaning force on the surface of the shadowless lamp 2 according to the adjustment amplitude of the adjusting mechanism 6.

[0034] Before the operation, the doctor adjusts the angles of the two shadowless lamps 2 through the connecting mechanism 5 and wears the headlamp 3. The two shadowless lamps 2 cooperate with the headlamp 3 to illuminate the surgical field. When the concentration of surgical smoke is high, a large amount of rising smoke approaches the lens of the shadowless lamp 2, thereby affecting the light intensity of the shadowless lamp 2. At this time, the doctor actively adjusts the light intensity of the headlamp 3 through the adjusting mechanism 6, so that when the smoke generated by surgical electrocoagulation affects the illumination of the shadowless lamp 2, the light intensity of the surgical area still keeps the surgical field clear, and at the same time adjusts the overlapping range of the two shadowless lamps 2. As the illumination areas of the two shadowless lamps 2 gradually overlap, the light intensity of the headlamp 3 gradually decreases, thereby reducing the energy consumption of the surgical headlamp 3, avoiding the need to replace new batteries due to insufficient power supply of the headlamp 3 during long-term surgery, affecting the rhythm and speed of the surgery. When the shadowless lamp 2 is adjusted because the smoke affects the light intensity, the processing mechanism 7 is set to increase the cleaning intensity of the surface of the shadowless lamp 2 according to the adjustment range of the shadowless lamp 2, to avoid the two shadowless lamps 2 The angle is still affected by a large amount of surgical smoke. The light intensity is affected.

[0035] The connecting mechanism 5 includes two connecting rods 50, which are rotatably connected to the outer side of the fixed seat 1. The end of the connecting rod 50 away from the fixed seat 1 is rotatably connected to the connecting rod 2 51, and the end of the connecting rod 2 51 away from the connecting rod 1 50 is rotatably connected to the connecting frame 52. The two shadowless lamps 2 are respectively located on the inner sides of the two connecting frames 52. The connecting rod 1 50 is a cross bar, and the connecting rod 2 51 is an L-shaped bar. Before the operation, the doctor drives the shadowless lamp 2 to rotate around the fixed seat 1 as the axis through the connecting rod 1 50, and the connecting rod 2 51 rotates around the end of the connecting rod 1 50, so that the shadowless lamp 2 swings left and right, and the connecting rod 2 51 is rotatably connected to the connecting frame 52, so that the shadowless lamp 2 swings up and down to cooperate with the doctor to adjust the two shadowless lamps 2, thereby illuminating the surgical field.

[0036] The adjustment mechanism 6 includes support rings 60 respectively installed on the outside of the two shadowless lamps 2. Two rotating shafts 61 are fixedly connected to the outside of the support ring 60. The two rotating shafts 61 are set at an interval of 180°. The rotating shafts 61 are rotatably connected to the inner wall of the connecting frame 52. One of the rotating shafts 61 is fixedly connected to a servo motor 62. The servo motor 62 is installed on the outside of the connecting frame 52. An adjusting part 63 for adjusting the brightness of the headlight 3 is provided on the outside of one of the connecting frames 52. The adjusting part 63 controls the operation of the two servo motors 62 according to the lighting intensity of the headlight 3.

[0037] When the concentration of surgical smoke is high, a large amount of rising smoke approaches the lens of the shadowless lamp 2, thereby affecting the light intensity of the shadowless lamp 2. At this time, the doctor adjusts the brightness of the headlamp 3 through the adjustment member 63, and the headlamp 3 compensates for the light intensity of the shadowless lamp 2 affected by the smoke, so that the light intensity of the operating area monitored by the light sensor 4 remains unchanged. When the brightness adjustment of the headlamp 3 is completed, the adjustment member 63 controls the two servo motors 62 to work according to the brightness adjustment amplitude of the headlamp 3, and the servo motor 62 drives the rotating shaft 61 to rotate, and the rotating shaft 61 drives the shadowless lamp 2 to rotate, so that the two shadowless lamps 2 rotate synchronously, increasing The overlapping area of ​​the two shadowless lamps 2 allows more light to illuminate the operating area, thereby increasing the brightness of the surgical field. When the adjustment member 63 adjusts the two shadowless lamps 2 to gradually overlap, the light sensor 4 detects that the light intensity in the operating area has increased, and the adjustment member 63 synchronously reduces the brightness of the headlamp 3, so that the light intensity detected by the light sensor 4 remains unchanged, thereby avoiding excessive concentration of light, which in turn affects the clarity of the operating area, and reducing the energy consumption of the surgical headlamp 3, thereby avoiding insufficient power supply of the headlamp 3 during long-term surgery, which requires replacement of new batteries and affects the rhythm and speed of the surgery.

[0038] The adjusting member 63 includes a projection device 64 installed on the outside of one of the connecting frames 52. The projection device 64 includes a light source, a projection module and an equivalent negative refractive index optical flat lens. The light emitted by the light source is processed by the projection module and then transmitted to the equivalent negative refractive index optical flat lens. The equivalent negative refractive index optical flat lens enables the projection light to form a real image in the air. An infrared sensor 65 and a controller 66 are installed on the surface of the projection device 64. The controller 66 is also connected to the light sensor 4. The infrared sensor 65 captures the doctor's gestures and transmits the information to the controller 66. The controller 66 controls the illumination intensity of the headlight 3 and the operation of the two servo motors 62 according to the gesture information.

[0039] The projection device 64 projects the operation interface into the air in the form of a real image. The principle is the equivalent negative refractive index optical flat lens technology in the prior art. The equivalent negative refractive index optical flat lens has a special refractive property, which can cause the light to refract after passing through the lens, thereby changing the propagation direction of the light. Through precise optical design, it can ensure that the projected light forms a clear and stable image in the air for users to watch and operate. The infrared sensor 65 captures the doctor's operating gestures and converts them into computer instructions and transmits them to the controller 66. The controller 66 controls the brightness of the headlamp 3 and combines the light intensity information of the operating area monitored by the light sensor 4 to ensure that when the brightness of the headlamp 3 is reduced or increased, the light intensity of the operating area remains unchanged. Through the combination with the projection technology, the doctor can directly operate the control interface in the air to achieve contactless control.

[0040] The processing mechanism 7 includes two arc-shaped plates 70 fixed on the inner wall of the connecting frame 52, the two arc-shaped plates 70 are spaced 180° apart, a plurality of ventilation grooves 71 are opened on the inner wall of the arc-shaped plates 70, a plurality of nozzles 72 are installed on the outer side of the ventilation grooves 71, the nozzles 72 are connected to the ventilation grooves 71, an air bag 73 is installed on the outer side of the connecting frame 52, a plurality of ventilation grooves 71 are connected to the air bag 73, an air pump 74 is connected on the outer side of the air bag 73, the air pump 74 is installed on the outer side of the connecting frame 52, an attraction member 75 is provided on the outer side of the support ring 60, and a synchronization member 76 is provided on the inner wall of the ventilation groove 71 for adjusting the flow area in the ventilation groove 71 when the rotating shaft 61 rotates.

[0041] When a large amount of smoke generated by surgical electrocoagulation affects the lighting of the shadowless lamp 2, the overlapping area of ​​the two shadowless lamps 2 increases. At this time, when the servo motor 62 drives the rotating shaft 61 to rotate, the rotation of the rotating shaft 61 drives the synchronous member 76 to work. The synchronous member 76 reduces the flow cross-section of the gas in the ventilation groove 71, and the power of the air pump 74 remains unchanged. As a result, when the airflow in the airbag 73 passes through the ventilation groove 71 and enters the nozzle 72, the gas flow rate sprayed from the nozzle 72 increases, and the gas sprayed from the nozzle 72 is absorbed by the suction member 75 to cooperate with the collection of the smoke particles carried by the airflow, thereby increasing the cleaning intensity of the surface of the shadowless lamp 2 to avoid the two shadowless lamps 2 being affected by a large amount of surgical smoke after the angles are adjusted.

[0042] The suction member 75 includes a plurality of suction tubes 77 installed on the inner wall of the support ring 60, a collecting box 78 is installed on the outer side of the support ring 60, the collecting box 78 is connected to the plurality of suction tubes 77, a connecting tube 79 is installed on one end of the collecting box 78 away from the suction tube 77, and a negative pressure pump 710 is connected to one end of the connecting tube 79 away from the collecting box 78, and the negative pressure pump 710 is installed on the inner wall of the connecting frame 52.

[0043] When the suction member 75 is working, the negative pressure pump 710 generates negative pressure, and negative pressure is also generated in the collecting box 78 through the connecting tube 79. Therefore, when the suction tube 77 sucks in the outside air, the sucked air enters the collecting box 78 and is collected by the collecting box 78. An air wall is formed between the multiple nozzles 72 and the suction tube 77, and as the overlapping area between the two shadowless lamps 2 increases, the gas flow rate ejected by the nozzle 72 increases, so as to cope with the treatment of more smoke generated by electrocoagulation.

[0044] The synchronization member 76 includes a plurality of sealing plates 711 slidably connected to the inner wall of the arc plate 70, the plurality of sealing plates 711 are located on the outside of the ventilation groove 71, a movable frame 712 is fixedly connected to the outside of the sealing plate 711, the movable frame 712 is slidably connected to the inner wall of the arc plate 70, a magnetic plate 713 is fixedly connected to the outside of the movable frame 712, the magnetic plate 713 is slidably connected to the inner wall of the arc plate 70, and a transmission member 714 is provided on the inner wall of the connecting frame 52 which drives the plurality of magnetic plates 713 to slide on the inner wall of the arc plate 70 as the rotating shaft 61 rotates.

[0045] When the rotating shaft 61 rotates, the rotating shaft 61 drives the transmission member 714 to work, and the transmission member 714 drives the magnetic plate 713 to slide on the inner wall of the arc plate 70. The magnetic plate 713 drives the moving frame 712 to move, and the moving frame 712 drives the sealing plate 711 to slide on the inner wall of the arc plate 70. When the sealing plate 711 moves, it enters the inner wall of the ventilation groove 71 to cooperate with reducing the gas flow area of ​​the ventilation groove 71.

[0046] The transmission member 714 includes a worm 715 fixedly connected to the end of the rotating shaft 61, the worm 715 is rotatably connected to the inner wall of the connecting frame 52, a worm wheel 716 is meshed on the outer side of the worm 715, the worm wheel 716 is rotatably connected to the inner wall of the connecting frame 52, a transmission gear 717 is fixedly connected to the end of the worm wheel 716, the worm wheel 716 and the transmission gear 717 rotate coaxially, a transmission plate 718 is slidably connected to the inner wall of the connecting frame 52, a transmission rack 719 is fixedly connected to the inner side of the transmission plate 718, the transmission gear 717 is meshed with the transmission rack 719, and a plurality of magnetic plates 720 are installed on the surface of the transmission plate 718, and the positions of the plurality of magnetic plates 720 respectively correspond to the positions of the plurality of magnetic plates 1 713, and the polarities of the opposite surfaces of the magnetic plate 1 713 and the magnetic plate 2 720 are opposite.

[0047] When the rotating shaft 61 rotates, the worm 715 is driven to rotate, and the worm 715 drives the outer worm wheel 716 to rotate, and the worm wheel 716 drives the transmission gear 717 to rotate, and the transmission gear 717 drives the transmission rack 719 to move, and the transmission rack 719 drives the transmission plate 718 to move. When the transmission plate 718 slides on the inner wall of the connecting frame 52, it drives multiple magnetic plates 720 to move at the same time. Since the positions of the multiple magnetic plates 720 correspond to the positions of the multiple magnetic plates 1 713 respectively, the opposite surfaces of the magnetic plates 1 713 and the magnetic plates 2 720 have opposite polarities, according to the principle of mutual attraction of opposite magnetic poles in magnetism, when the magnetic plate 2 720 moves, through the attraction between the magnetic plate 1 713 and the magnetic plate 2 720, the magnetic plate 2 720 will drive the magnetic plate 1 713 to move synchronously, so as to cooperate with the adjustment of the gas flow cross section in the ventilation groove 71.

[0048] Embodiment 2

[0049] In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that the positions of the multiple nozzles 72 and the suction tubes 77 are alternately distributed. The gas ejected from the nozzles 72 forms a certain pressure and flow rate to blow away the surrounding air or particles, and the suction tubes 77 are responsible for sucking away the blown particles or pollutants, thereby improving the cleanliness. The alternating distribution design can be adjusted and optimized according to actual needs. By increasing or decreasing the number or spacing of the nozzles 72 and the suction tubes 77, it can adapt to different working environments and conditions and enhance stability and flexibility.
