Description

Technical Field

[0001] This application relates to a gynecological visual endoscope, belonging to the field of medical device technology. Background Technology

[0002] Gynecologic endoscopic instruments are commonly used diagnostic and therapeutic instruments in gynecological clinics. They are mainly used for visual examination of the vagina, cervix, and other areas. They are an important tool for the early detection of gynecological diseases such as cervical lesions and vaginal inflammation. They are widely used in gynecological clinics of hospitals at all levels and maternal and child health care institutions. Their performance directly affects the accuracy of the examination and the patient's comfort.

[0003] A Chinese patent with publication number CN202321880370.X discloses a commonly used gynecoscope. This design includes a handle and a dilator, with the dilator connected to the upper end of the handle to open the vagina for observation. However, the lens in this design has a fixed angle structure, only allowing a forward view. It cannot flexibly adjust its direction according to the physiological curvature of the vagina and cervix, resulting in a limited detection area and difficulty in fully covering the examination site. Blind spots are easily created, especially in hidden areas such as the cervical canal, where lesions are easily missed, affecting diagnostic accuracy. To locate the lesion, the doctor needs to frequently move the dilator, causing greater discomfort to the patient and potentially damaging the vaginal mucosa.

[0004] In addition, the layout of the operation buttons on traditional ophthalmoscopes is unreasonable and does not conform to ergonomic design. During long-term operation, doctors find it inconvenient to observe, their operational accuracy decreases, and the risk of operator fatigue and errors increases.

[0005] Therefore, a new gynecological endoscopic technique is needed to solve problems such as inflexible lens adjustment, blind spots in the field of view, operator fatigue, and poor adaptability. Summary of the Invention

[0006] The purpose of this invention is to provide a gynecological visual examination endoscope to solve the technical problems existing in the prior art, such as inflexible lens adjustment, blind spots in the field of view, operator fatigue, and poor adaptability.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: The present invention provides a gynecological visual endoscope, including a handle and a dilator, the dilator being connected to a first end of the handle, and also including a lens disposed within the dilator, the lens being adjustable and rotatable.

[0008] The lens can be flexibly adjusted according to the physiological curvature of the vagina and cervix. Through the bending and rotation functions, a larger observation area can be covered without moving the dilator, effectively reducing blind spots and avoiding missing lesions.

[0009] Furthermore, the dilator is transparent and duckbill-shaped. The transparent material allows doctors to directly observe the inside of the vagina, and the duckbill-shaped structure conforms to the physiological morphology of the vagina, gently stretching the vaginal walls and reducing discomfort for the patient.

[0010] Furthermore, the dilator includes an adjustment mechanism. The adjustment mechanism is used to adjust the opening angle of the dilator, which can be flexibly adjusted according to the body size of different patients and the depth of the examination site, improving adaptability and avoiding patient discomfort or limited observation caused by the dilator opening too large or too small.

[0011] Preferably, the adjustment mechanism includes a support arm and a toothed buckle. The support arm provides mechanical support, and the toothed buckle achieves multi-level locking through its toothed structure. The doctor can select an appropriate opening angle as needed and fix it with the buckle to ensure that the dilator remains stable during the examination.

[0012] Preferably, the lens is rotatable 360°. The 360° rotation function allows the lens to cover all directions of the vagina and cervix. Without moving the dilator, the tissue surface at different angles can be observed by rotating the lens, fully covering the examination area and avoiding blind spots.

[0013] Furthermore, the handle includes a first operating part and a second operating part. The first operating part and the second operating part are respectively used to control the rotation and bending functions of the lens. The separate design of the operating parts facilitates one-handed operation by the doctor, improving operating efficiency and accuracy.

[0014] Preferably, the first operating part is a circular button, and the second operating part is a long, rectangular push button. The circular button is suitable for rotational operation, allowing the doctor to control the lens rotation by pressing or rotating the button; the long, rectangular push button is suitable for push-pull operation, allowing the doctor to control the lens bending by pushing or pulling the push button. This button layout conforms to ergonomic design, ensuring natural and smooth operation and reducing operator fatigue during prolonged examinations.

[0015] Furthermore, it also includes a bending mechanism connected to the lens for driving the lens to bend. The bending mechanism responds to the doctor's operating instructions, driving the lens to bend within a certain angle range, allowing the lens to adapt to the physiological curvature of the vagina and cervix, and enabling observation of the tissue surface in concealed areas.

[0016] Furthermore, it also includes a rotating mechanism connected to the lens for driving the lens to rotate. The rotating mechanism responds to the doctor's operating commands, driving the lens to rotate within the dilator to achieve observation of the tissue surface from different directions.

[0017] Preferably, the bending mechanism includes a pull cable and a pull cable drive unit. One end of the pull cable is connected to the lens, and the other end is connected to the pull cable drive unit. The pull cable drive unit pulls the pull cable to bend the front end of the lens, thereby achieving the bending function. The pull cable structure is simple and reliable, has high transmission efficiency, and can precisely control the bending angle of the lens.

[0018] Preferably, the rotating mechanism includes a rotating drive unit and a transmission unit, with the transmission unit connecting the rotating drive unit and the lens. The rotating drive unit transmits rotational power to the lens through the transmission unit, driving the lens to rotate. The transmission unit can employ gear transmission, belt transmission, or direct connection, etc., to ensure smooth and stable rotation.

[0019] Preferably, the first operating part is connected to the rotating mechanism, and the second operating part is connected to the bending mechanism. The doctor controls the lens rotation by operating the first operating part and controls the lens bending by operating the second operating part. The operation logic is clear, conforms to ergonomic habits, and improves operational efficiency and accuracy.

[0020] Compared with the prior art, the present invention has the following beneficial effects: 1) This application utilizes an adjustable and rotatable lens, which can flexibly adjust its direction according to the physiological curvature of the vagina and cervix, covering hidden areas such as the cervical canal, effectively reducing blind spots, avoiding missed lesions, and significantly improving diagnostic accuracy. Compared to existing lenses with fixed angles that can only see structures in front, the lens of this invention can be freely adjusted and rotated within the dilator, expanding the observation range and providing superior diagnostic results.

[0021] 2) By setting an adjustable and rotatable lens inside the speculum, the doctor can achieve a larger observation area coverage without moving the speculum, simply by adjusting the lens. This reduces repeated stimulation and discomfort to the patient, avoids vaginal mucosal damage that may be caused by frequent movement of the speculum, and significantly improves patient comfort and examination safety.

[0022] 3) This application sets a first operating part and a second operating part on the handle, and assigns a circular button and a long strip push button to correspond to the rotation and bending functions respectively. The layout of the operating buttons conforms to the ergonomic design, allowing doctors to operate smoothly with one hand, reducing operational fatigue during long-term examinations, improving operational accuracy, and reducing the risk of operational errors.

[0023] 4) By setting an adjustment mechanism including a support arm and a toothed buckle on the expander, the opening angle of the expander can be flexibly adjusted according to the patient's body size and the depth of the examination site, which improves the adaptability of the equipment to different patients, meets the diverse practical needs in clinical diagnosis and treatment, and expands the scope of application of the equipment.

Detailed Implementation

[0025] The present application is described in detail below with reference to the embodiments, but the present application is not limited to these embodiments.

[0026] Example 1 like Figure 1 As shown, this invention provides a gynecological visual endoscope, including a handle 1 and a dilator 2, with the dilator 2 connected to the first end of the handle 1. The dilator 2 is used to open the vagina to observe the internal condition of the vagina and cervix. The handle 1 is the part that the doctor holds and operates, facilitating one-handed operation of the visual endoscope.

[0027] The core improvement of this embodiment lies in the fact that the visual inspection endoscope also includes a lens 3, which is housed within the dilator 2. The lens 3 is used to acquire images of the vagina and cervix and transmit these images to a display device for the doctor's observation. The lens 3 has adjustable bending and rotating functions, allowing it to flexibly adjust its direction according to the physiological curvature of the vagina and cervix, covering a larger observation area without moving the dilator 2.

[0028] To enable the bending function of lens 3, the inspection endoscope also includes a bending mechanism 9. The bending mechanism 9 is connected to lens 3 and is used to drive the bending of lens 3. Specifically, the bending mechanism 9 includes a pull wire and a pull wire drive unit. One end of the pull wire is connected to lens 3, and the other end is connected to the pull wire drive unit. The pull wire drive unit pulls the pull wire, causing the front end of lens 3 to bend, thus achieving the bending function. The pull wire structure is simple and reliable, with high transmission efficiency, and can precisely control the bending angle of lens 3. By operating the pull wire drive unit, the doctor can bend lens 3 within a certain angle range, thereby observing the tissue surface in hidden areas such as the cervical canal, effectively reducing blind spots and avoiding missing lesions.

[0029] To enable the rotation function of lens 3, the ophthalmoscope also includes a rotation mechanism 10. The rotation mechanism 10 is connected to lens 3 and is used to drive lens 3 to rotate. Specifically, the rotation mechanism 10 includes a rotation drive unit and a transmission unit, with the transmission unit connecting the rotation drive unit and lens 3. The rotation drive unit transmits rotational power to lens 3 through the transmission unit, driving lens 3 to rotate. The transmission unit can employ gear transmission, belt transmission, or direct connection, ensuring smooth and stable rotation. By operating the rotation drive unit, the doctor can rotate lens 3 within dilator 2, thereby observing tissue surfaces in different directions and comprehensively covering the examination area.

[0030] Through the aforementioned structure, the gynecological visual endoscope of this embodiment can achieve greater coverage of the vagina and cervix by adjusting the lens 3 without moving the dilator 2. This reduces repeated stimulation and discomfort to the patient, avoids vaginal mucosal damage that may be caused by frequent movement of the dilator 2, and significantly improves patient comfort and examination safety. Simultaneously, the flexible adjustment function of the lens 3 allows doctors to observe lesions in hidden areas, significantly improving diagnostic accuracy.

[0031] Example 2 Based on Example 1, such as Figure 2 As shown, the structure of the dilator 2 has been optimized in this embodiment. The dilator 2 is a transparent duckbill-shaped structure. The transparent material allows doctors to directly observe the inside of the vagina. The duckbill-shaped structure conforms to the physiological shape of the vagina and can gently stretch the vaginal wall, reducing discomfort to the patient.

[0032] The expander 2 also includes an adjustment mechanism 4, which is used to adjust the opening angle of the expander 2. The adjustment mechanism 4 includes a support arm 5 and a toothed latch 6. The support arm 5 provides mechanical support, and the toothed latch 6 achieves multi-level locking through its toothed structure. Doctors can flexibly adjust the opening angle of the expander 2 according to different patients' body shapes and the depth of the examination site, and fix it in a suitable position using the toothed latch 6, ensuring that the expander 2 remains stable during the examination. This design of the adjustment mechanism 4 improves the adaptability of the ophthalmoscope to different patients, meets the diverse practical needs in clinical diagnosis and treatment, and expands the applicability of the equipment.

[0033] In this embodiment, the lens 3 can rotate 360 ​​degrees. The 360-degree rotation function allows the lens 3 to cover all directions of the vagina and cervix. Without moving the dilator 2, the tissue surface at different angles can be observed by rotating the lens 3, fully covering the examination area and avoiding blind spots.

[0034] Example 3 Based on Example 1 or Example 2, such as Figure 3As shown, this embodiment features ergonomically optimized operating components for the handle 1. The handle 1 includes a first operating part 7 and a second operating part 8. The first operating part 7 and the second operating part 8 are respectively used to control the rotation and bending functions of the lens 3. The separate design of the operating components facilitates single-handed operation by the doctor, improving operational efficiency and accuracy.

[0035] Specifically, the first operating part 7 is a circular button, and the second operating part 8 is a long, rectangular push button. The circular button is suitable for rotational operation, allowing doctors to control the rotation of the lens 3 by pressing or rotating the button. The long, rectangular push button is suitable for push-pull operation, allowing doctors to control the bending of the lens 3 by pushing or pulling the push button. This button layout conforms to ergonomic design, ensuring natural and smooth operation and reducing operator fatigue during prolonged examinations.

[0036] The first operating unit 7 is connected to the rotating mechanism 10, and the second operating unit 8 is connected to the bending mechanism 9. The doctor controls the rotation of the lens 3 by operating the first operating unit 7 and the bending of the lens 3 by operating the second operating unit 8. The operation logic is clear, conforms to ergonomic habits, and improves operational efficiency and accuracy. When the doctor needs to observe tissue surfaces from different directions, they can press or rotate the first operating unit 7, and the rotating mechanism 10 will respond to the operation command and drive the lens 3 to rotate. When the doctor needs to observe concealed areas, they can push or pull the second operating unit 8, and the bending mechanism 9 will respond to the operation command and drive the lens 3 to bend.
