Description

A new type of urinary endoscope Technical Field

[0001] This invention relates to the field of urological examination technology, specifically to a novel urological endoscope. Background Technology

[0002] A urinary endoscope is a medical device used for the examination and treatment of the urinary system. It mainly includes cystoscopes, ureteroscopes, etc. Existing urinary endoscopes, such as the portable video urethroscope disclosed in publication number "CN113197539A", use an elastic transparent sac to open the urethra, allowing the pinhole camera to obtain a wider field of view and the camera part is wrinkle-free. However, the camera's own shooting angle cannot be changed. When it is necessary to examine the affected area of ​​the urethral wall, if the transparent sac is located at the front of the affected area, it will affect the viewing effect. If the transparent sac is located at the affected area, it will increase the patient's pain and reduce the practicality of actual use.

[0003] Summary of the Invention

[0004] The purpose of this invention is to provide a novel urinary endoscope to solve the problems mentioned in the background art, where the camera's shooting angle cannot be changed, and when it is necessary to examine the affected area of ​​the urethral wall, if the transparent sac is located at the front of the affected area and expanded, it will affect the viewing effect. Furthermore, if the transparent sac is located at the affected area and expanded, it will increase the patient's pain and reduce the practicality of actual use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A novel urological endoscope includes an operating base, one end of which is fixedly connected to an insertion tube. An operating cavity is formed between the operating base and the insertion tube. A first mounting cavity is formed on the surface of the insertion tube. A positioning block is fixedly connected to the inner wall of one end of the first mounting cavity. An opening is provided on the surface of the positioning block, and a camera body is mounted on the inner wall of the opening of the positioning block. A positioning cylinder is fixedly connected to one end of the camera body, and a connecting wire is provided at one end of the positioning cylinder. A first adjustment groove and a second adjustment groove are formed inside the insertion tube. A first adjustment airbag is fixedly connected between the opening of one end of the first adjustment groove and the inner wall of the first mounting cavity. A second adjustment airbag is fixedly connected between the opening of one end of the second adjustment groove and the inner wall of the first mounting cavity. A groove is provided on the outer surface of the operating base, and a support airbag is fixedly connected to the inner wall of the groove on the outer surface of the operating base.

[0006] Compared with the prior art, the beneficial effects of the present invention are: This novel urinary endoscope:

[0007] 1. The device is equipped with a positioning block and protective rubber pads. During operation, the spherical design of the positioning block and the camera body allows the camera body to rotate and adjust at multiple angles within the opening of the positioning block, improving the flexibility of the camera body. Furthermore, the two annular protective rubber pads adhere to the surface of the camera body, which helps to block liquids in the environment during use, thus protecting the camera body and extending its service life. At the same time, the protective rubber pads also increase the support effect on the camera body, making it easier to cushion the camera body and reduce damage.

[0008] 2. The device is equipped with a positioning cylinder and a first adjusting airbag. When the device is working, the inflation and deflation of the first and second adjusting slots facilitates the control of the deformation of the first and second adjusting airbags. This, in turn, drives one end of the positioning cylinder to move in multiple directions. Subsequently, the positioning cylinder drives the camera body at the other end to adjust its angle. This facilitates the control of the camera body to view the affected area during operation. Furthermore, the two springs on the surface of the positioning cylinder improve its stability and facilitate automatic reset and correction, thus enhancing its practicality.

[0009] 3. Equipped with a transmission gear and a linkage gear plate, the device inflates the support airbag via the support air groove during operation. This allows the inflated airbag to support the urethra, thereby limiting and fixing the insertion tube. This improves the stability of examining the affected area and subsequent treatment. A micro motor drives the transmission gear to rotate, which in turn causes the linkage gear plate to rotate relative to the center of the second mounting cavity. The linkage gear plate then moves the supplementary light, allowing for rapid adjustment of the supplementary light angle and further enhancing the examination effect. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please refer to Figures 1-10. This invention provides a technical solution: a novel urinary endoscope, comprising an operating base 1, an insertion tube 2, an operating cavity 3, a first mounting cavity 4, a positioning block 5, a protective pad 6, a camera body 7, a positioning cylinder 8, a connecting wire 9, a first adjustment groove 10, a second adjustment groove 11, a first adjustment airbag 12, a second adjustment airbag 13, a support airbag 14, a support air groove 15, a second mounting cavity 16, a supplementary light 17, a micro motor 18, a transmission gear 19, a linkage gear plate 20, and a wire harness slot 21. The operating base 1 has an insertion tube 2 fixedly connected to one end, and an opening is formed between the operating base 1 and the insertion tube 2. The device has an operating cavity 3, a spherical positioning block 5 with a circular opening on its surface, and protective rubber pads 6 fixed to the inner walls of the openings at both ends of the positioning block 5. The protective rubber pads 6 are annular and their surfaces are in contact with the outer surface of the camera body 7. The camera body 7 is spherical. The first mounting cavity 4, the first adjustment groove 10, the second adjustment groove 11, the support air groove 15, and the wire harness groove 21 in this device are all connected to the operating base 1. When using this device, the insertion tube 2 is inserted into the patient's urethra for examination, the camera body 7 is supported by the positioning block 5 for examination, and the treatment instrument is inserted through the operating cavity 3 for operation.

[0023] The surface of the insertion tube 2 is provided with a first mounting cavity 4. A positioning block 5 is fixedly connected to the inner wall of one end of the first mounting cavity 4. The surface of the positioning block 5 is provided with an opening, and the inner wall of the opening of the positioning block 5 is equipped with a camera body 7. The first adjustment groove 10 is connected to the first adjustment airbag 12, and the second adjustment groove 11 is connected to the second adjustment airbag 13. The first adjustment airbag 12 and the second adjustment airbag 13 are arranged perpendicular to each other, and the first adjustment airbag 12 and the second adjustment airbag 13 are respectively fixedly connected to the outer surface of the positioning cylinder 8. During operation, the support airbag 14 is inflated through the support air groove 15, so that the annular support airbag 14 can expand and fit against the inner wall of the urethra, thereby limiting and fixing the insertion tube 2, which can improve the stability of examination and subsequent treatment.

[0024] A positioning cylinder 8 is fixedly connected to one end of the camera body 7, and a connecting wire 9 is provided at one end of the positioning cylinder 8. Two springs are connected between the outer surface of the positioning cylinder 8 and the inner wall of the first mounting cavity 4. The two springs on the outer surface of the positioning cylinder 8 are symmetrically arranged with the first adjusting airbag 12 and the second adjusting airbag 13, respectively. The supporting airbag 14 has a ring design, and a supporting air groove 15 is opened between the cavity of the supporting airbag 14 and the insertion tube 2. When it is necessary to adjust the angle of the camera body 7, the deformation of the first adjusting airbag 12 and the second adjusting airbag 13 is controlled by inflating or deflating the first adjusting groove 10 and the second adjusting groove 11. The first and second adjusting airbags 12 and 13 drive one end of the positioning cylinder 8 to move at multiple angles. When the first adjusting airbag 12 and 13 drive the positioning cylinder 8 respectively, it moves in four directions: up, down, left, and right. When the first adjusting airbag 12 and 13 drive the positioning cylinder 8 at the same time, it moves in an additional four directions. By adjusting the amount of gas in the first adjusting groove 10 and the second adjusting groove 11, it is easy to drive the positioning cylinder 8 to make fine adjustments to its angle, which further improves the inspection effect of this device. The spring on the outer surface of the positioning cylinder 8 will improve the stability of its movement. After the positioning cylinder 8 moves, it drives the camera body 7 at the other end to rotate.

[0025] The insertion tube 2 has a first adjustment groove 10 and a second adjustment groove 11 inside. A first adjustment airbag 12 is fixedly connected between the opening of one end of the first adjustment groove 10 and the inner wall of the first mounting cavity 4. A second mounting cavity 16 is formed on the end surface of the insertion tube 2. A supplementary light 17 is installed in the second mounting cavity 16. A micro motor 18 is fixed to the inner wall of the second mounting cavity 16, and a transmission gear 19 is fixed to the output end of the micro motor 18. A linkage gear plate 20 is fixedly connected to one side of the supplementary light 17. The lower inner wall of the second mounting cavity 16 has an arc-shaped design. The linkage gear plate 20... The camera body 7 is designed with an arc shape, and the center of the linkage toothed plate 20 coincides with the center of the inner wall of the lower end of the second mounting cavity 16. The linkage toothed plate 20 and the second mounting cavity 16 form a rotating connection. Since both the camera body 7 and the positioning block 5 are spherical, the camera body 7 can roll freely in the opening of the positioning block 5, which greatly improves the field of view during inspection. In addition, the two annular protective rubber pads 6 are attached to the outer surfaces of both ends of the camera body 7, which helps to block external impurities, reduce damage to the camera body 7 and internal parts, and extend the service life of the device.

[0026] A second adjusting airbag 13 is fixedly connected between the opening of one end of the second adjusting groove 11 and the inner wall of the first mounting cavity 4. A groove is provided on the outer surface of the operating base 1, and a supporting airbag 14 is fixedly connected to the inner wall of the groove on the outer surface of the operating base 1. A toothed block is provided on the outer surface of the linkage toothed plate 20, and the linkage toothed plate 20 is meshed with the transmission gear 19 through the toothed block. A wire harness slot 21 is opened between one end of the second mounting cavity 16 and the insertion tube 2. The surface of the linkage toothed plate 20 facing the wire harness slot 21 is provided with... The device has a groove, and the inner wall of the groove of the linkage toothed plate 20 is connected to the supplementary light 17. When the device is working, the wire is inserted into the groove of the linkage toothed plate 20 through the wire harness slot 21, so that the wire can be connected to the supplementary light 17. When it is necessary to adjust the supplementary light angle during operation, the micro motor 18 drives the transmission gear 19 to rotate, and the transmission gear 19 drives the linkage toothed plate 20 to rotate in a circle through the tooth block. At the same time, the linkage toothed plate 20 drives the supplementary light 17 to change the illumination angle, which improves the inspection effect of the device.

[0027] Working principle: When using this new type of urinary endoscope, the insertion tube 2 is first inserted into the patient's urethra. Then, the support balloon 14 is inflated through the support air groove 15, which expands the patient's urethra and fixes the insertion tube 2, facilitating operation and treatment through the operating chamber 3. When it is necessary to change the angle of the camera body 7, the first adjustment groove 10 and the second adjustment groove 11 are inflated or deflated to change the deformation degree of the first adjustment balloon 12 and the second adjustment balloon 13. This allows the first adjustment balloon 12 and the second adjustment balloon 13 to drive the positioning cylinder 8 to move, which in turn drives the camera body 7 at the other end to move within the opening of the positioning block 5, thereby increasing the examination range. The two protective rubber pads 6 help protect the camera body 7 and reduce the entry of impurities that could cause damage. The micro motor 18 drives the transmission gear 19 to rotate, which in turn drives the linkage gear plate 20 and the supplementary light 17 to move, thereby changing the supplementary light angle and improving the examination effect, thus increasing the overall practicality.
