Description

Technical Field

[0001] The present application relates to the technical field of medical instruments, and in particular to a hysteroscope. Background Art

[0002] A hysteroscope is a medical device used to treat gynecological diseases. It is often used to examine gynecological hemorrhagic diseases and intrauterine lesions. Sometimes it is used in combination with other medical devices to treat the patient's lesions. A traditional hysteroscope consists of a grip, a probe, a probe, a lighting system and an adjustment system. During use, the medical staff holds the grip of the hysteroscope and inserts the probe into the uterine cavity. The probe and the lighting system will observe the inside of the uterine cavity. The medical staff also changes the direction of observation by adjusting the direction of the probe and the lighting system. This type of hysteroscope has the advantages of simple structure, easy use and low cost, and is currently the most widely used type.

[0003] Although the existing hysteroscope has many advantages as mentioned above, it still has certain limitations in actual use. After the hysteroscope is inserted into the uterine cavity, it will prop up the uterine cavity, thereby expanding the volume of the cavity to facilitate observation by medical personnel. This causes a large deformation of the uterine cavity. Coupled with the sensitivity caused by the lesions inside the uterine cavity, it will cause obvious discomfort and certain pain to the patient. In addition, in the process of the probe rod extending into the cavity, due to the certain stimulation of the cavity and the channel, the secretions produced will adhere to the probe and the lighting system, resulting in obstructed observation.

[0042] See also Figure 1-Figure 2 , Figure 8 and Figure 11-Figure 14The observation device 13 includes a connecting seat 131, the end of which is fixedly connected to the hollow rod 101 through a connecting plate, a second adjusting motor 132 is fixedly installed at the front end of the connecting seat 131, and a rotating seat 133 is fixedly installed at one end of the output shaft of the second adjusting motor 132, a camera 134 and a light 135 are arranged on the top of the rotating seat 133, and a 136 is arranged at the front end of the rotating seat 133, and 136 cooperates with the synchronous connecting rod 126. When the device is extended into the predetermined position of the uterine cavity, by pressing the control button 15, the second telescopic machine 9 is controlled to drive the adjusting device 10 forward, and at the same time, the second travel seat 105 also moves forward synchronously, so that the outer extension arm 106 and the guide device 1 4 is reduced, and under this action, the metal support bar 84 is squeezed and expanded outward, and will push the uterine cavity wall to move outward and form a cavity of a certain volume. At this time, the rotating seat 133 moves as a whole to the observation hole 122, and the camera 134 takes pictures and the light 135 illuminates, so as to observe the condition of the propped-up part of the uterine cavity, thereby reducing the discomfort caused to the patient during the use of the device. Compared with traditional equipment that requires the patient to fully prop up the contact part of the instrument, it will cause obvious discomfort and certain pain to the patient. The device involved in the present application document avoids this situation by propping up a local area in combination with multiple observations, thereby improving the practicality of the device.

[0043] During the process of inserting the instrument into the patient's body, the output shaft of the second telescopic machine 9 is in a retracted state, and the rotating seat 133 is completely inside the sponge lining 123 and wrapped by the synchronous rotating sleeve 121, thereby avoiding the problem of secretions being stained on the surface of the camera 134 and the light 135 due to external stimulation during the insertion process, resulting in unclear imaging or reduced light intensity. At the same time, when the operator needs to change the inspection position, the second telescopic machine 9 can be controlled to retract first through the control button 15, and then the insertion position of the device is changed, and the second telescopic machine 9 is controlled to extend by the same method. In this process, the rotating seat 133 will be in a state of being included by the sponge lining 123 again, thereby achieving one-time cleaning, avoiding the problem of secretions contaminating the camera 134 and the light 135 during observation, resulting in obstruction of observation, and improving the stability of the device during use.

During the observation process, the operator can rotate the first adjusting knob 3, and the output end of the first adjusting knob 3 is connected to the input end of the second adjusting motor 132 by means of signal control, so that The second adjusting motor 132 will control the rotating seat 133 to rotate, so that the camera 134 can observe the surrounding area, which increases the observable area after a single dilation, reduces the number of times the device needs to dilate the patient's uterine cavity, and avoids causing multiple discomfort to the patient. At the same time, during the rotation of the rotating seat 133, through the cooperation of the synchronization connecting rods 126 and 136, during the rotation, the synchronization device 12 as a whole will rotate synchronously with 136, ensuring that the camera 134 and the light 135 can always maintain a corresponding relationship with the observation hole 122 during the inspection, thereby improving the stability of the device during operation.

[0047] A contact switch is provided at the bottom of 136. When the second telescopic machine 9 controls the adjusting device 10 to extend, the synchronous connecting rod 126 will extend into the interior of 136 and contact the trigger switch at the bottom of 136. At this time, the camera 134 and the light 135 are in a state corresponding to the observation hole 122 and are in a working state. When the second telescopic machine 9 controls the adjusting device 10 to retract, the synchronous rotating sleeve 121 wraps the rotating seat 133 as a whole, and the camera 134 and the light 135 are in a shielded state. At this time, the synchronous connecting rod 126 is disconnected from the contact switch at the bottom of 136, so that the camera 134 and the light 135 are in a power-off and shutdown state, thereby minimizing the energy consumption of the device to the greatest extent and reducing the use cost of the device.

[0048] The method of use of the present invention is as follows

[0049] During use, the control button 15 is pressed to control the second telescopic machine 9 to drive the adjustment device 10 forward, and the second travel seat 105 also moves forward synchronously, so that the distance between the outer extension arm 106 and the guide device 14 is reduced. Under this action, the metal support bar 84 is squeezed and expanded outward, and will push the uterine cavity wall to move outward and form a cavity of a certain volume. At this time, the rotating seat 133 moves as a whole to the observation hole 122, and the camera 134 is used for filming, and the light 135 is used for illumination, so as to observe the condition of the propped-up part of the uterine cavity, thereby reducing the discomfort caused to the patient during the use of the device. In the process of inserting the device into the patient's body, the output shaft of the second telescopic machine 9 is in a retracted state, and the rotating seat 1 33 is completely inside the sponge liner 123 and is wrapped by the synchronous rotating sleeve 121. When the operator needs to change the inspection position, the second telescopic machine 9 can be controlled to retract by the control button 15 first, and then the insertion position of the device is changed, and the second telescopic machine 9 is controlled to extend by the same method. In this process, the rotating seat 133 will be in a state of being included in the sponge liner 123 again, thereby achieving one-time cleaning. During the observation process, the operator can rotate the first adjusting knob 3, and the output end of the first adjusting knob 3 is connected to the input end of the second adjusting motor 132 by signal control, so that the second adjusting motor 132 will control the rotating seat 133 to rotate, so that the camera 134 can focus on the surrounding The observation is performed around the whole circle, which increases the observable area after a single expansion and reduces the number of times the device needs to expand the patient's uterine cavity. During the rotation of the rotating seat 133, through the cooperation of the synchronous connecting rods 126 and 136, during the rotation, the synchronization device 12 will rotate synchronously with 136 as a whole, ensuring that the camera 134 and the light 135 can always maintain a corresponding relationship with the observation hole 122 during the inspection. When it is necessary to adjust the fluctuation degree of the metal support bar 84, the output end of the second adjustment knob 4 can be connected to the input end of the first adjustment motor 103 by signal control, so as to control the first adjustment motor 103 to rotate, and through the effect of thread drive, the second travel seat 105 and the first adjustment seat 105 can be adjusted. The spacing of the motor 103, when the spacing between the second stroke seat 105 and the first adjustment motor 103 decreases, the fluctuation of the metal strut 84 increases, and the supporting amplitude of the patient's uterine cavity is larger. When the spacing between the second stroke seat 105 and the first adjustment motor 103 increases, the fluctuation of the metal strut 84 decreases, and the supporting amplitude of the patient's uterine cavity is reduced. When the patient cannot bear the stimulation caused by the support of the device, the fluctuation of the metal strut 84 can be appropriately adjusted to minimize the stimulation to the patient while ensuring the observation effect. The extension amount of the first telescopic machine 81 can also be controlled to change the effective length of the metal strut 84 and make more targeted adjustments. When the second telescopic machine 9 controls the adjustment device 10 to extend,The synchronous link 126 will extend into the interior of 136 and contact the trigger switch at the bottom of 136. At this time, the camera 134 and the light 135 are in a state corresponding to the observation hole 122 and are in a working state. When the second telescopic machine 9 controls the adjustment device 10 to retract, the synchronous rotating sleeve 121 will wrap the rotating seat 133 as a whole, and the camera 134 and the light 135 are in a shielded state. At this time, the synchronous link 126 is disconnected from the contact switch at the bottom of 136, so that the camera 134 and the light 135 are in a power-off and shutdown state, thereby minimizing the energy consumption of the device.
