Technical Field
[0001] This invention belongs to the field of camera technology, and in particular relates to a surgical field camera device with illumination function. Background Technology
[0002] A surgical field camera is a device used to film the surgical area and record the entire surgical procedure; it is part of an operating room teaching system or a digital operating room. The main function of a surgical field camera is to film the surgical area and record the surgical process to facilitate teaching and academic exchange. It is a core component of the operating room teaching system or digital operating room and directly affects the final outcome.
[0003] Existing surgical field cameras are mainly divided into head-mounted and mounted types. Head-mounted surgical field cameras are usually mounted on a headgear, worn by the surgeon, and use wireless transmission. This method offers excellent field of view, is simple to install, small in size, and easy to carry, but requires higher technical skills. Mounted surgical field cameras are installed inside the handle of the surgical lamp. This method can better utilize the surgical lamp as a camera position and offers a good field of view, but due to limited space in the handle, only one camera lens can be installed, and the surgical lamp needs to be modified, making it relatively more difficult. In addition, existing head-mounted surgical field cameras lack suitable lighting devices, resulting in shadows during the surgical procedure, which makes it difficult to clearly record the entire surgical process.
[0004] Therefore, it is necessary to invent a surgical field camera device with illumination function to solve the above problems. Summary of the Invention
[0005] To address the aforementioned problems, the present invention provides a surgical field camera device with illumination function to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a surgical field camera device with illumination function, comprising a flexible housing, an adjustable elastic band connecting the two ends of the rear side of the flexible housing, a mounting hole on the front side of the flexible housing, a camera mounted in the mounting hole, the front lens of the camera protruding forward in a cylindrical shape, the rear end of the camera being spherical and rotatably mounted in the mounting hole, an illumination component sleeved on the front end of the camera, a rotation adjustment mechanism for adjusting the camera angle connected to the rear side of the camera, two distance sensors symmetrically mounted on the front side of the flexible housing, and several adjustment buttons mounted on the top of the flexible housing.
[0007] Furthermore, the lighting assembly includes a fixing sleeve, which is detachably fitted onto the front end of the camera. Gaps exist between the inner side of the fixing sleeve and the front end of the camera, as well as between the fixing sleeve and the sidewall of the mounting hole. From front to back, a fixing ring and a movable ring are sequentially arranged on the inner side of the fixing sleeve. Both the fixing ring and the movable ring are fitted onto the front end of the camera. The fixing ring is fixedly connected to the fixing sleeve, and the movable ring is slidably connected to the fixing sleeve. Multiple first through holes and multiple second through holes are respectively opened at the same positions on the front and rear sides of the fixing ring and the movable ring. The holes are evenly distributed in a ring. The same lever is inserted through the first and second through holes at the same position. The lever is rotatably connected to both sides of the first through hole. An LED is installed at the front end of the lever. The rear end of the lever is inserted into the second through hole. A limit rod is inserted through the two sides of the rear end of the lever. Limit grooves are opened on the inner walls of both sides of the second through hole. The front end of the limit groove is inclined towards the direction of the camera axis. Both ends of the limit rod are slidably installed in the two limit grooves. Multiple miniature electric push rods are vertically fixedly connected between the rear side of the movable ring and the rear inner wall of the fixed sleeve.
[0008] Furthermore, a pressing block is slidably installed in the limiting groove. The pressing block is located in front of the limiting rod, and the side of the pressing block opposite to the limiting rod is designed with an arc surface. A compression spring is fixedly connected between the front side of the pressing block and the inner wall of the front side of the limiting groove, and the pressing block can always be pressed together with the limiting rod under the support of the compression spring.
[0009] Furthermore, a focusing cover is fixedly sleeved around the LED bead, and when the fixed ring and the movable ring are pressed together, the focusing cover tilts towards the direction of the camera axis.
[0010] Furthermore, the rear side of the flexible shell has a smooth arc design, and an arc-shaped flexible support frame is installed on the rear side of the flexible shell. The flexible support frame is detachably covered with absorbent cotton cloth, and multiple support blocks are evenly fixedly connected between the upper and lower edges of the flexible support frame. The gap between the support blocks and the flexible support frame is filled with absorbent sponge.
[0011] Furthermore, the support block has a porous structure, and the thickness of the absorbent sponge matches the thickness of the support block.
[0012] Furthermore, the camera is equipped with a gyroscope and a microprocessor, and an optical compensation lens is installed on the front lens portion of the camera.
[0013] Furthermore, a wireless transmission module is installed inside the flexible shell, and the wireless transmission module is connected to an external display.
[0014] Furthermore, a protective cover is installed at the front end of the fixing sleeve, and the protective cover is made of high light transmittance glass.
[0015] Furthermore, a movable rod is fixedly connected to the rear end of the lamp bead. The movable rod is slidably inserted into the front end of the lever. A return spring is fixedly connected between the rear end of the movable rod and the interior of the lever. A top rod is hinged to the top of the movable rod, and the top of the top rod is tilted backward. A strip-shaped hole is opened through the top of the lever, and the top of the top rod passes through the strip-shaped hole and is hinged to the top inner wall of the first through hole.
[0016] The technical effects and advantages of this invention are as follows: 1. The present invention includes an illumination component. During the operation of the camera, the LEDs in the illumination component can illuminate the shooting position from different angles, thereby achieving a "shadowless" effect at the shooting position and improving the clarity of the shot. Furthermore, the multiple LEDs in the illumination component can adjust the illumination distance according to the distance of the shooting position, thereby further improving the illumination effect on the shooting position. 2. By incorporating a compression spring, the present invention ensures that the limiting rod is supported by the compression spring as it moves along the limiting groove, thereby guaranteeing the stability of the limiting rod during movement and improving the stability of the lamp bead when adjusting its angle. 3. This invention incorporates a gyroscope and a processor. During camera operation, the gyroscope inside the camera can detect minute movements and transmit the signal to the microprocessor to immediately calculate the amount of displacement that needs to be compensated. Then, the optical compensation lens compensates for the camera's shaking direction and displacement, thereby effectively overcoming image blur caused by camera vibration. 4. By incorporating a wireless transmission module, this invention allows the video footage captured by the camera to be shared in real-time with the remote physician via an external display during the operation of the camera. This enables the physician to keep up with the progress of the surgery and helps in diagnosing the condition and resolving problems encountered during the operation. 5. This invention incorporates an absorbent sponge. When the flexible outer shell is worn on the doctor's forehead, the absorbent cotton cloth adheres tightly to the doctor's forehead under the action of the adjustable elastic band. At this time, the support block can support the absorbent sponge to prevent it from being compressed. At the same time, the porous structure of the support block can also maintain good breathability. Thus, during the use of this invention, when the doctor's forehead sweats, the absorbent sponge and absorbent cotton cloth can effectively absorb the sweat, preventing sweat from flowing into the doctor's eyes and affecting the doctor's surgical operation. 6. By providing a top rod, when it is necessary to focus the light emitted by the lamp bead to illuminate a farther location, as the front end of the lever moves upward, the top rod can push the lamp bead forward through the movable rod, thereby achieving upward deflection of the lamp bead while it moves forward, so that the light emitted by the lamp bead can be closer to the position to be illuminated, thus improving the lighting effect of the lamp bead.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0020] This invention provides, for example Figures 1 to 9The surgical field camera device with illumination function shown includes a flexible housing 1. An adjustable elastic band 2 is connected between the two ends of the rear side of the flexible housing 1. A mounting hole is opened on the front side of the flexible housing 1, and a camera 3 is installed in the mounting hole. The front lens of the camera 3 protrudes forward in a cylindrical shape, and the rear end of the camera 3 is spherical and is rotatably installed in the mounting hole. An illumination component 4 is sleeved on the front end of the camera 3. A rotation adjustment mechanism 5 for adjusting the angle of the camera 3 is connected to the rear side of the camera 3. Two distance sensors 6 are symmetrically installed on the front side of the flexible housing 1. Several adjustment buttons 7 are installed on the top of the flexible housing 1. A gyroscope and a microprocessor are installed inside the camera 3. An optical compensation lens is installed on the front lens part of the camera 3. A wireless transmission module is installed inside the flexible housing 1, and the wireless transmission module is connected to an external display. The lighting assembly 4 includes a fixing sleeve 40, which is detachably fitted onto the front end of the camera 3. Gaps exist between the inner side of the fixing sleeve 40 and the front end of the camera 3, and between the fixing sleeve 40 and the sidewall of the mounting hole. A fixing ring 41 and a movable ring 42 are sequentially arranged from front to back on the inner side of the fixing sleeve 40. Both the fixing ring 41 and the movable ring 42 are fitted onto the front end of the camera 3. The fixing ring 41 is fixedly connected to the fixing sleeve 40, and the movable ring 42 is slidably connected to the fixing sleeve 40. Multiple first through holes 43 and multiple second through holes 44 are respectively opened at the same positions on the front and rear sides of the fixing ring 41 and the movable ring 42, and the multiple first through holes 43 and multiple second through holes 44 are evenly distributed in a ring. A single lever 45 is inserted through the first through holes 43 and the second through holes 44 at the same positions. Both sides are rotatably connected to both sides of the first through hole 43. The front end of the lever 45 is equipped with an LED bead 46. The rear end of the lever 45 is inserted into the second through hole 44. A limit rod 47 is inserted through the two sides of the rear end of the lever 45. Limit grooves 48 are opened on both sides of the inner wall of the second through hole 44. The front end of the limit groove 48 is inclined towards the axis of the camera 3. Both ends of the limit rod 47 are slidably installed in the two limit grooves 48. Multiple miniature electric push rods 49 are vertically fixedly connected between the rear side of the movable ring 42 and the rear inner wall of the fixed sleeve 40. A protective cover 15 is installed at the front end of the fixed sleeve 40. The protective cover 15 is made of high light transmittance glass. A light-concentrating cover 10 is connected to the outer fixed sleeve 40 of the LED bead 46. When the fixed ring 41 and the movable ring 42 are pressed together, the light-concentrating cover 10 is inclined towards the axis of the camera 3. With the lighting component 4 installed, the camera 3 can be activated and take pictures by adjusting the button 7 during use. During operation, the distance sensor 6 detects the distance between the camera 3 and the shooting position, thereby controlling the activation of the miniature electric push rod 49. When the distance between the shooting position and the camera 3 becomes greater, the miniature electric push rod 49 gradually shortens, causing the movable ring 42 to move away from the fixed ring 41. As the movable ring 42 moves, the limiting rod 47 moves relative to the movable ring 42 along the limiting groove 48 towards the fixed ring 41. At this time, the front end of the lever 45 causes the LED bead 46 to gradually deflect away from the camera 3. As the LED beads 46 deflect, the light generated by the multiple LED beads 46 can converge in a farther direction under the action of the condenser 10, thereby meeting the lighting needs of long-distance shooting. Conversely, when the shooting position is close to the camera 3, the miniature electric push rod 49 can push the interactive ring to move closer to the fixed ring 41, so that the light generated by the multiple LED beads 46 can converge in a closer direction, thereby ensuring the lighting effect on the shooting position. Furthermore, since the light generated by the multiple LED beads 46 can illuminate the position to be shot from different angles, it can avoid the obstruction caused by the different shooting position angles, thereby achieving a "shadowless" effect and improving the clarity of the shooting. In addition, during the shooting process, the shooting angle of the camera 3 can be adjusted by controlling the rotation adjustment mechanism 5 through the adjustment button 7. Since the lighting component 4 is installed on the camera 3, the lighting component 4 can also change the illumination angle as the angle of the camera 3 is adjusted, thereby ensuring the lighting effect on the shooting position. By incorporating a gyroscope and a processor, during the operation of camera 3, the gyroscope inside camera 3 can detect minute movements and transmit the signal to the microprocessor to immediately calculate the amount of displacement that needs to be compensated. Then, the optical compensation mirror compensates for the image blur caused by camera vibration according to the direction of lens shake and the amount of displacement. With the addition of a wireless transmission module, the video footage captured by camera 3 during its operation can be shared in real time with the remote physician, allowing the physician to keep up with the progress of the surgery and help diagnose the condition and resolve problems encountered during the operation.
[0021] like Figure 8 and Figure 9 As shown, a pressing block 8 is slidably installed in the limiting groove 48. The pressing block 8 is located in front of the limiting rod 47, and the side of the pressing block 8 opposite to the limiting rod 47 is designed with an arc surface. A compression spring 9 is fixedly connected between the front side of the pressing block 8 and the inner wall of the front side of the limiting groove 48, and the pressing block 8 can always be pressed together with the limiting rod 47 under the support of the compression spring 9. When the limiting rod 47 moves along the limiting groove 48, the pressing block 8 can always support the limiting rod 47 under the action of the pressing spring 9, thereby ensuring the stability of the limiting rod 47 when it moves, and thus improving the stability of the lamp bead 46 when adjusting the angle.
[0022] like Figures 1 to 3 As shown, the rear side of the flexible shell 1 is a smooth arc surface design, and an arc-shaped flexible support frame 11 is installed on the rear side of the flexible shell 1. The flexible support frame 11 is detachably covered with a water-absorbing cotton cloth 12. Multiple support blocks 13 are evenly fixedly connected between the upper and lower edges of the flexible support frame 11. The gap between the support block 13 and the flexible support frame 11 is filled with a water-absorbing sponge 14. The support block 13 has a porous structure, and the thickness of the water-absorbing sponge 14 matches the thickness of the support block 13. When the flexible shell 1 is worn on the doctor's forehead, the absorbent cotton cloth 12 can fit snugly against the doctor's forehead under the action of the adjustable elastic band 2. At this time, the support block 13 can support the absorbent sponge 14 to prevent the absorbent sponge 14 from being compressed. At the same time, the porous structure of the support block 13 can also maintain good breathability. Thus, during the use of this invention, when the doctor's forehead sweats, the absorbent sponge 14 and the absorbent cotton cloth 12 can effectively absorb the sweat, preventing the sweat from flowing into the doctor's eyes and affecting the doctor's surgical operation.
[0023] like Figure 6 and Figure 7 As shown, a movable rod 16 is fixedly connected to the rear end of the lamp bead 46. The movable rod 16 is slidably inserted into the front end of the lever 45, and a return spring 17 is fixedly connected between the rear end of the movable rod 16 and the interior of the lever 45. A top rod 18 is hinged to the top end of the movable rod 16, and the top end of the top rod 18 is tilted backward. A strip hole is opened through the top of the lever 45, and the top end of the top rod 18 passes through the strip hole and is hinged to the top inner wall of the first through hole 43. With the push rod 18 provided, when it is necessary to focus the light emitted by the lamp bead 46 to a farther place, as the front end of the lever 45 moves upward, the push rod 18 can push the lamp bead 46 forward through the movable rod 16, thereby realizing that the lamp bead 46 deflects upward and moves forward at the same time. During this process, the return spring 17 is gradually stretched, and the pulling force of the return spring 17 on the movable rod 16 also makes the movement of the lamp bead 46 more stable, avoiding shaking during the movement of the lamp bead 46. As the LED bead 46 moves forward, the light emitted by the LED bead 46 can get closer to the position to be illuminated, thereby improving the lighting effect of the LED bead 46. When the light emitted by the LED 46 needs to be focused on a closer location for illumination, as the front end of the lever 45 deflects downward, the return spring 17 can cooperate with the push rod 18 to pull the LED 46 backward, thereby meeting the close-range illumination needs of the LED 46.
[0024] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
