Referring to fig. 1, a surgical illumination apparatus according to an embodiment of the present application includes a light source assembly 100, a projection assembly 200, and a light guide assembly 300. Referring to fig. 1 and 4, the light source assembly 100 is used for fixing on a wall or a ceiling, and the light source assembly 100 includes a light source 110. Referring to fig. 1 and 12, the projection assembly 200 has a light outlet 2121. Referring to fig. 1 and 6, the light guide assembly 300 is connected between the light source assembly 100 and the projection assembly 200, the light guide assembly 300 includes a light guide 310, light emitted from the light source 110 can be transmitted to the light outlet 2121 through the light guide 310, and the light guide 310 can be bent relative to the light source assembly 100 to adjust the position of the light outlet 2121.

In the above-mentioned operation lighting device, the light source assembly 100 is fixed on a wall or a ceiling, the light source 110 in the light source assembly 100 is used for emitting light, the light guide assembly 300 is connected between the light source assembly 100 and the projection assembly 200, and the light emitted by the light source 110 can be transmitted to the light outlet 2121 of the projection assembly 200 through the light guide tube 310 in the light guide assembly 300, so as to illuminate the operation area. Because the light pipe 310 can be bent relative to the light source assembly 100, when the irradiation angle and the irradiation area need to be adjusted, the height and the direction of the light outlet 2121 can be changed only by bending the light pipe 310, and the light source assembly 100 with a larger volume does not need to be moved, so that the operation is more convenient. In addition, the light emitted by the light source 110 is transmitted to the light outlet 2121 through the light pipe 310, and is not directly emitted to the operation area from the light source assembly 100, and the light source assembly 100 does not need to be arranged too low due to the extension of the length of the light pipe 310, so that the influence on the laminar flow of the operating room is smaller.

In some embodiments, the light pipe 310 may be a high-transmittance multi-component glass fiber, which has a long transmission distance and low optical loss. The optical fiber of proper type can be selected according to parameters such as divergence angle and the like.

Referring to fig. 6 to 8, in some embodiments, the light guide assembly 300 includes a bending tube 320, the bending tube 320 is sleeved outside the light guide tube 310, and the bending tube 320 includes a plurality of bone segments 321 sequentially disposed along the length direction of the light guide tube 310, and any two adjacent bone segments 321 are rotationally connected.

Specifically, condyle 321 may be formed from a rigid plastic, such as nylon. All bone segments 321 are hollow and columnar and can be divided into three types, namely a head bone segment 322 at the head end, a tail bone segment 324 at the tail end and a plurality of middle bone segments 323 between the head bone segment 322 and the tail bone segment 324. The cephalad condyle 322 is located near one end of the light source assembly 100 and the caudal condyle 324 is located near one end of the projection assembly 200. The rotational connection between any two adjacent bone segments 321 can adjust the position of the projection assembly 200 by the relative rotation of the adjacent bone segments 321, thereby adjusting the height and orientation of the light outlet 2121.

Referring to fig. 6 to 8, in some embodiments, among any adjacent three condyles 321, one condyle 321 located in the middle can relatively rotate about a first axis with respect to one condyle 321 at one end thereof, and can relatively rotate about a second axis with respect to one condyle 321 at the other end thereof, the first axis being perpendicular to the second axis.

Specifically, the first axis and the second axis are both perpendicular to the length direction of the light pipe 310. Any adjacent three bone segments 321 are respectively a first bone segment, a second bone segment and a third bone segment, which are sequentially connected. The first condyle may be rotatable relative to the second condyle about a first axis and the third condyle may be rotatable relative to the second condyle about a second axis. Since the first axis is perpendicular to the second axis, the first condyle and the third condyle are perpendicular to the direction of rotation of the second condyle. Thus, the position of the projection assembly 200 can be adjusted more flexibly by rotating in two directions, so that a wider range of illumination requirements can be met.

Of course, in other embodiments, the rotation directions of all adjacent condyles 321 may be the same.

Referring to fig. 6 to 8, in some embodiments, one of any two adjacent bone segments 321 is provided with a groove 3212, the other is provided with a bump 3211, the bump 3211 is clamped into the groove 3212 and can rotate around the rotation axis in the groove 3212, opposite ends of the two adjacent bone segments 321 are respectively provided with an avoidance notch 325, and the avoidance notch 325 is located at one side of the rotation axis.

Specifically, the groove 3212 is a circular groove and the bump 3211 is a circular bump 3211 so that the bump 3211 can rotate within the groove 3212. Among the two adjacent bone segments 321, the tail end of one bone segment 321 close to the head end is provided with an avoidance notch 325 sunken towards the head end, one of the two adjacent bone segments close to the tail end is provided with an avoidance notch 325 sunken towards the tail end, and the two avoidance notches 325 are communicated to form an avoidance space. When the adjacent condyles 321 rotate around the rotation axis, the avoidance space can avoid extrusion accumulation of partial areas caused by rotation of the condyles 321, so that the condyles 321 can smoothly realize relative rotation.

In some embodiments, the avoidance gap 325 is arc-shaped, and two adjacent avoidance gaps 325 are communicated to form a waist-like avoidance space.

Preferably, in some embodiments, one of the two adjacent bone segments 321 is provided with two protrusions 3211 disposed opposite to each other along the radial direction of the two adjacent bone segments, and the other is provided with two grooves 3212 disposed opposite to each other along the radial direction of the two adjacent bone segments, and each protrusion 3211 is snapped into a corresponding groove 3212 and can rotate in the corresponding groove 3212, and the rotation axis of the protrusion is the line connecting the two protrusions 3211 or the two grooves 3212. By arranging two sets of matched convex blocks 3211 and grooves 3212, the stability of relative rotation between the bone segments 321 can be improved.

In the embodiment shown in the drawings, of the three types of condyles, the end of the skull condyle 322 adjacent to the middle condyle 323 is provided with a first projection 3221 projecting toward the middle condyle 323. A first groove 3231 recessed toward a direction away from the head bone segment 322 is provided at an end of each intermediate bone segment 323 adjacent to the head bone segment 322, and a second protrusion 3232 protruding toward the tail bone segment 324 is provided at an end of each intermediate bone segment 323 adjacent to the tail bone segment 324. The end of the caudal condyle 324 adjacent to the medial condyle 323 is provided with a second groove 3241 recessed in a direction away from the medial condyle 323. The first projection 3221 of the head bone segment 322 is inserted into the first groove 3231 of the adjacent middle bone segment 323, and the first projection 3221 can rotate in the first groove 3231 to realize the relative rotation between the head bone segment 322 and the middle bone segment 323. Every two adjacent middle condyles 323 are inserted into the corresponding first grooves 3231 through the second protrusions 3232 and rotate therein, so that the adjacent middle condyles 323 can rotate relatively. All the middle condyles 323 have the same structure, and the placement positions of any two adjacent middle condyles 323 are different by 90 degrees in the circumferential direction, so that one middle of any three adjacent middle condyles 323 is vertical to the rotation directions of two opposite ends of the middle condyle, and the position adjustment of a plurality of angles is realized. The second tab 3232 on the endmost medial condyle 323 is inserted into and rotated within the second recess 3241 on the caudal condyle 324 to effect relative rotation between the caudal condyle 324 and the medial condyle 323.

Referring to fig. 6, 9 and 10, in some embodiments, the light guide assembly 300 includes a balloon tube 330 sandwiched between the light guide tube 310 and the bending tube 320, and the projection assembly 200 includes a sensor having a first state and a second state, the sensor being configured to sense operation to switch from the first state to the second state. In the first state, the balloon tube 330 is supported on the bending tube 320 to inhibit bending of the bending tube 320; in the second state, the balloon tube 330 is configured to deflate to release the bend inhibition of the bend tube 320.

Specifically, the balloon tube 330 is sleeved outside the light pipe 310, and the bending tube 320 is sleeved outside the balloon tube 330. A gum material with a suitable elastic coefficient, such as rubber, may be selected. When the balloon tube 330 is inflated with gas, the balloon tube 330 can expand, whereas upon release of the gas, the balloon tube 330 will collapse. In the first state, the air in the wall of the air bag tube 330 is sufficient, and the outer wall thereof can abut against the inner wall of the bending tube 320 to support the bending tube 320 and inhibit the relative rotation between the adjacent bone segments 321, thereby inhibiting the bending of the bending tube 320. At this time, the position of the light outlet 2121 in the projection assembly 200 is stable, so that stable illumination conditions can be provided to ensure that the operation is performed smoothly. To adjust the position of the light outlet 2121, the operator only needs to operate the projecting assembly 200, and the sensor in the projecting assembly 200 can sense the operation, such as touching, of the operator. When the operator touches the sensor, the air bag tube 330 will switch from the first state to the second state, the air in the tube wall of the air bag tube 330 is released, the pressure in the tube wall is reduced, the supporting force of the outer wall of the air bag tube 330 to the inner wall of the bending tube 320 is reduced, and the adjacent bone segments 321 of the bending tube 320 can rotate relatively, so that the bending of the bending tube 320 is realized, and the position of the light outlet 2121 is adjusted. In this way, the supporting force of the air bag tube 330 to the bending tube 320 can be changed according to the illumination requirement, so that the bending tube 320 can be bent when needed, and can be stably maintained after the adjustment is completed.

In some embodiments, the air tube 333 is connected to the wall of the air tube 330, the air tube 333 is connected to the air pump, and an air valve is disposed between the air tube 333 and the air pump, and the air valve, the air pump and the sensor are all in communication connection with the control module 400, when the sensor is excited, the sensor sends a signal to the control module 400, and the control module 400 controls the air pump and the air valve to open, so that a part of the air in the wall of the air tube 330 is pumped out, and the supporting force of the outer wall of the air tube on the inner wall of the bending tube 320 is reduced. When the adjustment is completed, the control module 400 controls the air pump to pump air into the wall of the air bag tube 330 and controls the air valve to close.

In some embodiments, the sensor is a capacitive sensor.

Preferably, in some embodiments, the projection assembly 200 includes at least two sensors, all of which sense operation (i.e., are activated) before switching to the second state. The setting can avoid the state switching caused by the false touch, and the sensing accuracy is improved.

Referring to fig. 6, 9 and 10, in some embodiments, the balloon tube 330 includes a tubular balloon body 331 and a plurality of balloon convex hulls 332 distributed on an outer wall of the balloon body 331; in the first state, a portion of the balloon convex hull 332 extends into the relief notch 325 in the condyle.

Specifically, in the first state, the gas in the wall of the balloon tube 330 is sufficient, the outer wall of the balloon main body 331 will abut against the inner wall of the bending tube 320 to support the same, and meanwhile, the balloon convex hull 332 located at the avoidance gap 325 will extend outwards into the avoidance gap 325 to fill the avoidance gap 325 and inhibit the relative rotation between the adjacent bone segments 321, thereby inhibiting the bending of the bending tube 320.

Referring to fig. 6, in some embodiments, a hose cover 340 is further sleeved on the outer portion of the bending tube 320, and the hose cover 340 may protect the bending tube 320. The hose cover 340 may be a stainless steel spiral tube, a steel wire PVC hose, a thin-skin silicone tube, or the like.

Referring to fig. 6, in some embodiments, a flange 350 is further connected to the head end of the light pipe 310, and is used to fixedly connect with the light source assembly 100.

Referring to fig. 11 to 13, in some embodiments, the projection assembly 200 includes a projection housing 210 and a reflection member 220, the reflection member 220 is fixed at a light emitting end of the light pipe 310, the projection housing 210 is disposed outside the reflection member 220, the light emitting opening 2121 is disposed at the projection housing 210, the reflection member 220 is configured to reflect the light transmitted through the light pipe 310 to an inner wall of the projection housing 210, and the inner wall of the projection housing 210 is configured to reflect the light to the light emitting opening 2121.

Specifically, the projection cover 210 includes a coupling portion 211 and a projection portion 212, where the coupling portion 211 is coupled to the outside of the reflecting member 220, the projection portion 212 is in a hollow hemispherical shape, and the inner wall of the projection portion 212 is a mirror surface, so that light can be reflected by the reflecting member 220, and the light can be reflected to the inner wall of the projection portion 212 to reach the light outlet 2121.

Referring to fig. 11-12, in some embodiments, the projection mask 210 is threadably coupled to the reflector 220, and the projection mask 210 is configured to operably rotate to move relative to the reflector 220.

Specifically, the projection assembly 200 includes a sterile handle 230, the sterile handle 230 is sleeved outside the sleeve joint 211 of the projection cover 210, and the sterile handle 230 and the sleeve joint are fixedly connected, and an operator can rotate the sterile handle 230 to drive the projection cover 210 to rotate. Since the reflecting member 220 is fixed to the light emitting end of the light pipe 310, when the aseptic handle 230 is rotated, the projection hood 210 will move along the reflecting member 220, so as to change the distance between the reflecting member 220 and the inner wall of the projection hood 210, thereby adjusting the size of the light spot reflected to the light emitting port 2121 by the inner wall of the projection hood 210. So, alright in the art according to the illumination demand to the facula size adjust, the flexibility of use is higher.

Referring to fig. 11 to 12, further, in some embodiments, the reflecting member 220 includes a light outlet 221 and a reflecting mirror 222, the light outlet 221 is fixed at a light outlet end of the light guide 310, the reflecting mirror 222 is connected to an end of the light outlet 221 facing away from the light guide 310, the light guide 310 is used for transmitting light to the reflecting mirror 222 through the light outlet 221, and the reflecting mirror 222 is used for reflecting the light to an inner wall of the projection hood 210.

Specifically, the light outlet pipe 221 is in a hollow column shape, and the light outlet end of the light guide pipe 310 is inserted into the light outlet pipe 221, and the two are in interference fit to achieve fixation. The reflector 222 is fixedly connected with one end of the light outlet pipe 221 away from the light guide pipe 310 through a connecting piece 223, and a space exists between the reflector 222 and the light outlet pipe 221 so as to leave a channel for light reflection. The sleeving part 211 is sleeved outside the light outlet pipe 221 and is in threaded connection with the light outlet pipe 221, and the projection part 212 is covered outside the reflector 222 and the connecting piece 223. The light emitted from the light emitting end of the light pipe 310 enters the light emitting pipe 221, is projected from the light emitting pipe 221 to the reflecting mirror 222, is reflected by the reflecting mirror 222 to the inner wall of the projecting part 212, and is reflected by the inner wall of the projecting part 212 to reach the light emitting port 2121. When the sterile handle 230 is rotated, the projection mask 210 will move along the light exit tube 221, thereby changing the spacing of the mirror 222 from the inner wall of the projection mask 210, and thereby adjusting the size of the light spot reflected by the inner wall of the projection mask 210 to the light exit 2121.

Referring to fig. 12-14, in some embodiments, the sterile handle 230 includes a first shell 231 and a second shell 232 that are snap-fit to clamp the hub 211.

Referring to fig. 11 to 12, in some embodiments, the outer wall of the light pipe 221 is provided with a receiving groove 2211, and the aforementioned sensor is disposed in the receiving groove 2211.
