Description

Technical Field

[0001] The present invention relates to the technical field of obstetrics and gynecology examinations, and particularly to an obstetrics and gynecology endoscope examination device with an adaptive lighting system. Background Art

[0002] When performing obstetrics and gynecology endoscope examinations, lights are circumferentially and evenly distributed at the front end of the endoscope for illumination, so as to illuminate the pathological site, making the imaging clear and facilitating doctors' observation. However, when the existing front-end lighting system of the endoscope is performing examinations, when the target tissue range is large, in order to cover the target area with the monitoring range of the endoscope, it is necessary to appropriately increase the distance from the target tissue. At this time, the light spot of a single light source irradiating the target tissue has a weak brightness due to the long distance, resulting in unclear imaging. When the target tissue range is small, close observation can be made. At this time, the light spots of a single light source irradiating the target tissue will partially overlap, and because the distance is relatively close, the light spot irradiating on the target tissue is brighter, making the overlapping part of the light spot even brighter, resulting in overexposure and unclear imaging, thus affecting the examination results. Summary of the Invention

[0003] Aiming at the deficiencies of the existing technology, the present invention provides an obstetrics and gynecology endoscope examination device with an adaptive lighting system.

[0004] In order to achieve the above object, the technical solution of the present invention is as follows:

[0006] A body;

[0007] Range measuring sensors, which are circumferentially and evenly distributed on the body and are used for detecting the distance between the front end of the endoscope and the target tissue in real time;

[0008] A driving member, which is arranged inside the body;

[0009] A lighting unit circumferentially and evenly distributed on the body, which is driven by the driving member to deflect radially according to the distance measured by the range measuring sensor to adjust the lighting range;

[0014] An annular plate, on which an arc-shaped groove is provided for guiding cooperation with the free end of the arc-shaped blade. When the annular plate rotates, the free end of the arc-shaped blade is pushed by the groove wall of the arc-shaped groove to rotate around the hinge end, so as to realize the radial expansion or contraction of the aperture adjusting member, and thus realize the dynamic adjustment of the light passing aperture;

[0015] Pneumatic response units circumferentially and uniformly arranged in the body, which include:

[0016] Piston cylinders symmetrically arranged on the rotation path of the lamp tube;

[0017] A piston plate, which is axially elastically arranged in the piston cylinder and is in transmission connection with the lamp tube;

[0018] An annular telescopic member arranged in the lamp tube, which telescopically expands and contracts in a ring shape around the central axis of the lamp tube. The annular telescopic member includes:

[0019] A sliding block slidably arranged along the telescopic direction, which is in transmission connection with the annular plate;

[0020] Bellows symmetrically arranged, which is communicated with the corresponding side piston cylinder, and the telescopic end is fixedly connected with the sliding block;

[0021] The pneumatic response unit is configured as:

[0022] When the lamp tube rotates, it drives the piston plate to adjust the air pressure compression in the piston cylinder;

[0023] The bellows corresponding to the compressed side piston cylinder extends, and the other side contracts synchronously, so as to drive the sliding block to drive the annular plate to rotate.

[0024] Preferably, sliding columns and limiting columns are respectively fixedly arranged on both surfaces of the arc-shaped blade. The sliding columns are slidably arranged in the arc-shaped groove, and the limiting columns are slidably arranged in the radial grooves formed on the inner wall of the front end of the lamp tube.

[0025] Preferably, when the distance measured by the distance measuring sensor between the front end of the endoscope and the target tissue is within the preset range, the lamp tube remains axially arranged in the initial state, and the sliding column remains at the middle of the arc-shaped groove in the initial state.

[0026] Preferably, when the distance measured by the distance measuring sensor between the front end of the endoscope and the target tissue is greater than the maximum value of the preset range, the front end of the lamp tube radially deflects away from the central axis of the body, and the sliding column slides from the middle to the outer ring direction of the arc-shaped groove in the arc-shaped groove, so as to radially expand the aperture adjusting member.

[0027] Preferably, when the distance measured by the distance measuring sensor between the front end of the endoscope and the target tissue is less than the minimum value of the preset range, the lamp tube radially deflects towards the central axis of the body, and the sliding column slides from the middle to the inner ring direction of the arc-shaped groove in the arc-shaped groove, so as to radially contract the aperture adjusting member.

[0028] Preferably, when the lamp tube is in the initial position, the overlapping rate of adjacent lighting areas is 30%, and the deflection angle range of the lamp tube is ±15°.

[0029] Preferably, when the front end of the lamp tube deflects within 15° from the initial position in the direction away from the central axis of the body, the overlapping rate of adjacent lighting areas increases to 45%.

[0030] Preferably, when the front end of the lamp tube deflects within 15° radially in the direction close to the central axis of the body from the initial position, the overlapping rate of adjacent lighting areas decreases to 15%.

[0031] Preferably, a rubber ring is provided in the gap between the lamp tube and the front surface of the body.

[0032] Preferably, the driving member includes a moving ring driven to move axially by a hydraulic rod, and a connecting rod is hingedly arranged between the moving ring and the outer wall of the end of the lamp tube.

[0033] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0034] In the present invention, through the arranged distance measuring sensor, lamp tube, pneumatic response unit and aperture adjusting member, the lamp tube is driven by the driving member to deflect radially according to the distance measured by the distance measuring sensor to adjust the lighting range. While the lamp tube deflects, the outer wall of the end of the lamp tube pushes one of the contact plates symmetrically arranged on both sides of the end position of the lamp tube along the deflection path of the lamp tube to move, thereby driving the piston rod fixedly arranged between the contact plate and the piston plate to move synchronously, thereby driving the piston plate on the same side to move synchronously in the piston cylinder, thereby adjusting the air pressure compression in the piston cylinder, so that the gas in the piston cylinder enters the bellows on the corresponding side through the connecting hose, so that the telescopic end of the bellows on the corresponding side extends annularly around the central axis of the lamp tube, so that one side of the bellows connected to both sides of the sliding block is in an extended state, thereby driving the sliding block to slide along the telescopic direction, thereby driving the annular plate to rotate synchronously through the fixing rod fixedly arranged between the sliding block and the annular plate, thereby pushing the free end of the arc-shaped blade to rotate around the hinged end through the groove wall opened on the annular plate, thereby realizing the radial expansion or contraction of the aperture adjusting member, thereby realizing the dynamic adjustment of the light passing aperture, so that when adjusting the distance according to the size of the target tissue, the range of the lighting area can be adjusted synchronously, and while adjusting the range of the lighting area, the dynamic adaptive adjustment of the light passing aperture can be realized synchronously, so as to avoid unclear imaging caused by too dark or too bright light when adjusting the range of the lighting area, and effectively improve the imaging clarity and the accuracy of the detection result judgment.

[0048] It is easy to understand that according to the technical solution of the present invention, without changing the essence of the present invention, those of ordinary skill in the art can propose various interchangeable structural forms and implementation manners. Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0049] As Figures 1 - 11 shown, a gynecological and obstetric endoscope inspection device with an adaptive lighting system includes:

[0050] Body 1;

[0051] The distance measuring sensor 2, which is circumferentially distributed on the body 1 and is used to detect the distance between the front end of the endoscope and the target tissue in real time;

[0052] The driving member, which is arranged inside the body 1;

[0053] The lighting unit, which is circumferentially distributed on the body 1 and is driven by the driving member to deflect radially according to the distance measured by the distance measuring sensor 2 to adjust the lighting range;

[0054] The lighting unit includes:

[0055] The lamp tube 3 rotatably arranged, which has a clearance fit with the front end surface of the body 1;

[0056] The aperture adjusting member integrated at the front end of the lamp tube 3, which includes:

[0057] The arc-shaped blades 11 circumferentially distributed and hinged;

[0058] The annular plate 9, on which the arc-shaped groove 10 is provided for guiding cooperation with the free ends of the arc-shaped blades 11. When the annular plate 9 rotates, the free ends of the arc-shaped blades 11 are pushed by the groove wall of the arc-shaped groove 10 to rotate around the hinged ends, so as to realize the radial expansion or contraction of the aperture adjusting member, thereby realizing the dynamic adjustment of the light passing aperture;

[0059] The pneumatic response unit circumferentially distributed inside the body 1, which includes:

[0060] The piston cylinders 5 symmetrically arranged on the rotation path of the lamp tube 3;

[0061] The piston plate 6 axially elastically arranged inside the piston cylinder 5 and in transmission connection with the lamp tube 3;

[0062] A ring-shaped telescopic member disposed within the lamp tube 3, which telescopically expands and contracts in a ring shape around the central axis of the lamp tube 3. The ring-shaped telescopic member includes:

[0063] A sliding block 12 slidably disposed along the telescopic direction, which is in driving connection with the annular plate 9;

[0064] Symmetrically disposed bellows 8, which are communicated with the corresponding side piston cylinders 5, and the telescopic ends are fixedly connected to the sliding block 12;

[0065] The pneumatic response unit is configured to:

[0066] When the lamp tube 3 rotates, it drives the piston plate 6 to adjust the air pressure compression within the piston cylinder 5;

[0067] The bellows 8 corresponding to the compressed side piston cylinder 5 elongate, and the other side contracts synchronously to drive the sliding block 12 to drive the annular plate 9 to rotate.

[0068] Specifically, during gynecological and obstetric endoscopy examinations, lighting is provided by circumferentially and evenly distributing lighting lamps at the front end of the endoscope, thereby illuminating the pathological site, making the imaging clear and facilitating the doctor's observation. However, when the existing endoscope's front-end lighting system is in use, when the target tissue area is large, in order to cover the target area with the endoscope monitoring range, it is necessary to appropriately increase the distance from the target tissue. At this time, the light spot of a single lighting lamp illuminating the target tissue is weak due to the long distance, resulting in unclear imaging. When the target tissue area is small, it can be observed at a close distance. At this time, the light spots of a single lighting lamp illuminating the target tissue will partially overlap, and because the distance is relatively close, the light spot illuminating the target tissue is brighter, making the overlapping part of the light spot even brighter, resulting in overexposure and unclear imaging. The prior art cannot achieve adaptive adjustment, thus affecting the examination results. By circumferentially and evenly distributing distance measuring sensors 2 at the front end of the body 1, the distance between the front end of the endoscope and the target tissue is detected in real time, and the measured data is transmitted to the controller.

[0069] Furthermore, the controller dynamically adjusts the lighting range according to the distance measured by the distance measuring sensor 2. The controller drives the lamp tubes 3 circumferentially and evenly distributed on the body 1 to deflect radially through the driving member, thereby adjusting the size of the lighting area of the front end of the lamp tube 3 illuminating the tissue. Thus, when adjusting the distance according to the size of the target tissue, the size of the lighting area is synchronously adjusted to achieve the adjustment of the adaptive lighting range and improve the imaging clarity of the endoscope.

[0070] Further, while the lamp tube 3 deflects, the outer wall of the end of the lamp tube 3 pushes against and moves one of the contact plates 7 symmetrically arranged on both sides of the end position of the lamp tube 3 along the deflection path of the lamp tube 3, thereby driving the piston rod fixedly arranged between the contact plate 7 and the piston plate 6 to move synchronously, thereby driving the piston plate 6 on the same side to move synchronously in the piston cylinder 5, thereby adjusting the air pressure compression in the piston cylinder 5, so that the gas in the piston cylinder 5 enters the bellows 8 on the corresponding side through the connecting hose, so that the telescopic end of the corresponding side bellows 8 extends annularly around the central axis of the lamp tube 3. When the lamp tube 3 is in the initial position, the outer walls on both sides of the lamp tube 3 are in contact with the contact plates 7 on both sides, and the piston plate 6 is pushed by the piston rod to compress the spring. When the outer wall of the end of the lamp tube 3 pushes against and moves one of the contact plates 7 and continues to compress the spring, the spring in the piston cylinder 5 on the other side pushes the piston plate 6 to move in the reverse direction due to the restoration of deformation, thereby adjusting the air pressure in the piston cylinder 5 on that side to be negative pressure and sucking the gas in the bellows 8 communicated with the piston cylinder 5 on that side, so that the telescopic end of the bellows 8 on that side contracts annularly, so that one side of the bellows 8 connected to both sides of the sliding block 12 is in the extended state, and the other side adaptively changes to the contracted state, thereby driving the sliding block 12 to slide along the telescopic direction, thereby driving the annular plate 9 to rotate synchronously through the fixing rod fixedly arranged between the sliding block 12 and the annular plate 9, thereby pushing the free end of the arc-shaped blade 11 to rotate around the hinge end through the groove wall opened on the annular plate 9, thereby realizing the radial expansion or contraction of the aperture adjusting member, thereby realizing the dynamic adjustment of the light passing aperture, so that when adjusting the distance according to the range size of the target tissue, the range size of the illumination area can be synchronously adjusted, and while adjusting the range size of the illumination area, the dynamic adaptive adjustment of the light passing aperture can be synchronously realized, so as to avoid unclear imaging caused by too dark or too bright light when adjusting the range size of the illumination area, and effectively improve the imaging clarity and the accuracy of the detection result judgment.

[0071] It should be noted that the driving member drives the lamp tube 3 to deflect radially. The driving member can be directly driven by a hydraulic rod, or can be driven by a motor screw rod in cooperation, or any technical means well-known to those skilled in the art can be used.

[0072] Sliding columns and limiting columns are respectively fixedly arranged on the two side surfaces of the arc-shaped blade 11. The sliding columns are slidably arranged in the arc-shaped grooves 10, and the limiting columns are slidably arranged in the radial grooves opened on the inner wall of the front end of the lamp tube 3.

[0073] Specifically, the sliding block 12 slides along the telescopic direction, thereby driving the annular plate 9 to rotate synchronously through the fixing rod fixedly arranged between the sliding block 12 and the annular plate 9, thereby pushing the free end of the arc-shaped blade 11 to rotate around the hinge end through the groove wall opened on the annular plate 9, and through the limiting cooperation of the limiting column and the radial groove, thereby ensuring the radial expansion or contraction of the aperture adjusting member, thereby realizing the dynamic adjustment of the light passing aperture.

[0074] The distance measuring sensor 2 detects that the distance between the front end of the endoscope and the target tissue is within the preset range. The lamp tube 3 maintains its initial axial setting, and the sliding column remains at its initial position in the middle of the arc-shaped groove 10.

[0075] Specifically, when the distance measuring sensor 2 detects that the distance between the front end of the endoscope and the target tissue is within the preset range, the lamp tube 3 maintains its initial state. The initial state of the lamp tube 3 is a circumferential state parallel to the central axis of the main body 1. At this time, the sliding column is also in its initial state and is located in the middle of the arc-shaped groove 10.

[0076] When the distance measuring sensor 2 detects that the distance between the front end of the endoscope and the target tissue is greater than the maximum value of the preset range, the front end of the lamp tube 3 deflects radially away from the central axis of the main body 1, and the sliding column slides from the middle to the outer circle direction of the annular plate 9 in the arc-shaped groove 10, so as to radially expand the aperture adjusting member.

[0077] Specifically, when the distance measuring sensor 2 detects that the distance between the front end of the endoscope and the target tissue is greater than the maximum value of the preset range, the front end of the lamp tube 3 is driven by a driving member to deflect radially away from the central axis of the main body 1, thereby driving the outer wall of the end of the lamp tube 3 to push against and move the contact plate 7 provided on one side of the fixed sleeve 4 located inside the main body 1 and coaxially arranged with the main body 1. Thereby, the piston plate 6 is driven by the piston rod to move in the piston cylinder 5, and the spring is further compressed, thereby adjusting the air pressure compression in the piston cylinder 5 fixedly provided on the fixed sleeve 4. Thereby, the gas in the piston cylinder 5 is compressed through the connecting hose and enters the bellows 8 on the corresponding side. The internal air pressure of the bellows 8 increases, thereby driving the telescopic end of the bellows 8 to extend annularly around the central axis of the lamp tube 3 in the lamp tube 3. At the same time, the spring in the piston cylinder 5 fixedly provided on the inner wall of the main body 1 restores its deformation due to the loss of the push of the lamp tube 3, thereby driving the piston plate 6 to move in the direction away from the inner wall of the main body 1, thereby adjusting the internal air pressure of the piston cylinder 5 to be negative pressure, thereby sucking the gas in the bellows 8 on the corresponding side, so that the telescopic end of the bellows 8 on this side contracts annularly, thereby driving the sliding block 12 to move circumferentially around the central axis of the lamp tube 3, thereby driving the annular plate 9 to rotate through the fixing rod.

[0078] Further, the annular plate 9 rotates, driving the arc-shaped groove 10 to rotate synchronously. As a result, the sliding column moves relative to the arc-shaped groove 10 from the middle towards the outer circle direction of the annular plate 9, driving the free end of the arc-shaped blade 11 to rotate around the hinged end towards the outer circle direction of the annular plate 9. This drives the aperture adjusting member to expand radially, increasing the light transmission aperture. Consequently, the illumination area of a single lamp tube becomes larger, enhancing the edge overlap rate of adjacent illumination areas and increasing the light intensity at the edge. This effectively avoids the problem of weak light intensity at the edge of the light spot formed by a single illuminating lamp due to a long distance to the target tissue, effectively improving the uniformity of the light spot brightness formed by long-distance illumination and the clarity of long-distance illumination imaging.

[0079] When the distance measuring sensor 2 detects that the distance between the front end of the endoscope and the target tissue is less than the minimum value of the preset range, the lamp tube 3 deflects radially towards the central axis direction of the body 1, and the sliding column slides from the middle towards the inner circle direction of the annular plate 9 within the arc-shaped groove 10, causing the radial contraction of the aperture adjusting member.

[0080] Specifically, when the distance measuring sensor 2 detects that the distance between the front end of the endoscope and the target tissue is less than the minimum value of the preset range, the front end of the lamp tube 3 is driven by a driving member to deflect radially towards the central axis direction of the body 1, driving the outer wall of the end of the lamp tube 3 to push against the contact plate 7 near the inner wall of the body 1 and move. This drives the piston plate 6 to move within the piston cylinder 5 through the piston rod and further compresses the spring, thereby adjusting the air pressure compression within the piston cylinder 5 fixedly arranged on the inner wall of the body 1. Then, the gas within the piston cylinder 5 is compressed through the connecting hose and enters the bellows 8 on the corresponding side. The internal air pressure of the bellows 8 increases, driving the telescopic end of the bellows 8 to extend annularly around the central axis of the lamp tube 3 within the lamp tube 3. At the same time, the spring within the piston cylinder 5 fixedly arranged on the outer wall of the fixed sleeve 4 restores its deformation due to the loss of the push from the lamp tube 3, driving the piston plate 6 to move away from the fixed sleeve 4, thereby adjusting the internal air pressure of the piston cylinder 5 to be negative pressure and sucking the gas within the bellows 8 on the corresponding side. As a result, the telescopic end of the bellows 8 on this side contracts annularly, driving the sliding block 12 to move circumferentially around the central axis of the lamp tube 3, and then driving the annular plate 9 to rotate through the fixed rod.

[0081] Further, the annular plate 9 rotates, driving the arc-shaped groove 10 to rotate synchronously. As a result, the sliding column moves relative to the arc-shaped groove 10 from the middle towards the inner circle direction of the annular plate 9, driving the free end of the arc-shaped blade 11 to rotate towards the inner circle direction of the annular plate 9 around the hinged end. This drives the light aperture adjusting member to contract radially, reducing the light passing aperture, thereby decreasing the illumination area of a single lamp tube, reducing the edge overlap rate of adjacent illumination areas, weakening the illumination brightness at the edge, effectively preventing partial overlap of the light spots irradiated by a single illuminating lamp on the target tissue. Since the distance is relatively close, the light spots irradiated on the target tissue are relatively bright, making the overlapping light spots brighter, and thus avoiding the problem of unclear imaging caused by overexposure, improving the imaging clarity during close-range irradiation, achieving adaptive adjustment according to the distance, and enhancing the practicality and adaptability of the device.

[0082] When the lamp tube 3 is in the initial position, the overlap rate of adjacent illumination areas is 30%, and the deflection angle range of the lamp tube 3 is ±15°.

[0083] When the front end of the lamp tube 3 deflects within the range of 15° from the initial position towards the direction away from the central axis of the main body 1, the overlap rate of adjacent illumination areas increases to 45%.

[0084] Specifically, when the front end of the lamp tube 3 deflects 5° from the initial position towards the direction away from the central axis of the main body 1, the overlap rate of adjacent illumination areas increases to 35%, initially expanding the illumination coverage range, reducing the dark area transition between adjacent areas, and improving the basic illumination uniformity. When the front end of the lamp tube 3 deflects 10° from the initial position towards the direction away from the central axis of the main body 1, the overlap rate of adjacent illumination areas increases to 40%, significantly enhancing the area overlap effect and strengthening the edge illumination brightness. When the front end of the lamp tube 3 deflects 15° from the initial position towards the direction away from the central axis of the main body 1, the overlap rate of adjacent illumination areas increases to 45%, maximizing the overlap rate and forming a continuous and seamless illumination surface, thus forming a gradient-style adaptive illumination adjustment.

[0085] When the front end of the lamp tube 3 deflects radially within 15° from the initial position towards the direction close to the central axis of the main body 1, the overlap rate of adjacent illumination areas decreases to 15%.

[0086] Specifically, when the front end of the lamp tube 3 deflects 5° from the initial position towards the central axis of the main body 1, the overlap rate of adjacent illumination areas is reduced to 25%, reducing the overlap of adjacent areas and expanding the independent illumination range of a single lamp. When the front end of the lamp tube 3 deflects 10° from the initial position towards the central axis of the main body 1, the overlap rate of adjacent illumination areas is reduced to 20%, significantly compressing the overlapping area and strengthening the illumination boundary of a single lamp. When the front end of the lamp tube 3 deflects 15° from the initial position towards the central axis of the main body 1, the overlap rate of adjacent illumination areas is reduced to 15%, minimizing the overlap rate and forming an independent illumination unit, thereby forming a gradient-type adaptive illumination adjustment.

[0087] A rubber ring is provided in the gap between the lamp tube 3 and the front surface of the main body 1.

[0088] Specifically, the rubber ring provided in the gap between the lamp tube 3 and the front surface of the main body 1 seals the gap, provides a deflection space for the lamp tube 3, and at the same time increases the deflection distance of the end of the lamp tube 3, so that during the small-angle deflection process of the lamp tube 3, the end can have a large displacement amount to push against the contact plate 7 to move and adjust the air pressure in the piston cylinder 5, ensuring the stability of the adaptive adjustment system.

[0089] The driving member includes a moving ring driven to move axially by a hydraulic rod, and a connecting rod is hingedly provided between the outer wall of the end of the lamp tube 3 and the moving ring.

[0090] Specifically, driving the hydraulic rod drives the moving ring to move on the fixed sleeve 4, thereby driving the connecting rod to pull or push the end of the lamp tube 3 to deflect.

[0091] The technical scope of the present invention is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
