Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to a visual suction tube anti-fog lens. Background Technology

[0002] Hysteroscopy is a minimally invasive gynecological diagnostic and treatment technique. A small instrument equipped with a light source and camera is inserted into the uterus to provide real-time, magnified observation of the cervical canal and uterine cavity. It has become an important auxiliary tool for gynecological clinical diagnosis and treatment. Hysteroscopy has the advantages of being intuitive, accurate, and minimally invasive, and can be used to diagnose various diseases such as abnormal uterine bleeding, infertility, and intrauterine foreign bodies. During the examination, doctors can clearly observe the morphology and lesions within the uterine cavity through the hysteroscope's view.

[0003] During hysteroscopy, a suction tube is typically used, often equipped with a visual probe to facilitate the doctor's manipulation and examination of the uterine cavity. However, existing suction tubes present several problems. Because the probe tube and the handle are often fixedly connected, the doctor must rotate the entire device to adjust the angle of the visual probe and the opening in the suction tube. This is not only cumbersome but also particularly inconvenient when operating with one hand. Furthermore, during rotation, the opening in the probe tube can easily scratch the uterine cavity wall, causing additional pain and risks to the patient.

[0004] These issues limit the convenience and safety of hysteroscopy, thus necessitating a suction tube device that can be adjusted more flexibly and avoids scratching the uterine cavity wall. Utility Model Content

[0005] This utility model addresses the problem that existing technical solutions are too simplistic by providing a visual suction tube anti-fog lens that is significantly different from existing technologies, thus solving the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a visual suction tube anti-fog lens, comprising a housing, a probe tube and a connecting tube respectively installed on both sides of the housing, a lamp head for illumination installed at the end of the probe tube, an opening on the outer wall of the probe tube near the lamp head, a visual lens for easy observation of the uterine cavity installed in the opening, an anti-scratching structure for preventing the probe tube from scratching the inner wall of the uterine cavity between the probe tube and the housing, and a rotating structure for rotating and adjusting the probe tube to change the field of view angle installed on the housing.

[0007] Preferably, the end of the detector tube closest to the lamp head and the opening is inclined, and the detector tube and the housing are rotatably connected.

[0008] Preferably, the viewing lens is installed at an angle inside the opening, and the viewing lens is provided with a hydrophilic anti-fog coating.

[0009] Preferably, the anti-scratch structure includes an anti-scratch part and a control part, and the anti-scratch part includes an airbag, a connecting tube, a support groove and a cavity. An airbag is provided on the outer wall of the detection tube near the opening. The airbag is connected to the support groove through the connecting tube. The support groove communicates with the cavity. Both the support groove and the cavity are opened inside the housing.

[0010] Preferably, the control unit includes a piston plate, a pressing rod, and a return spring. The piston plate is provided inside the cavity, and the bottom of the piston plate is connected to the pressing rod. The end of the pressing rod passes through the bottom of the housing, and the pressing rod is fitted with a return spring. The two ends of the return spring are respectively connected to the bottom of the cavity and the bottom of the piston plate.

[0011] Preferably, the rotating structure includes a rotating wheel, a mounting port, a groove, a locking block, and a locking spring. The housing has a mounting port extending through both end faces. The rotating wheel is installed in the mounting port and connected to the outer wall of the detection tube. A groove is provided in the housing below the mounting port. A locking block is connected in the groove. A locking spring is connected between the locking block and the groove. The end of the locking block is engaged with the rotating wheel.

[0012] Preferably, the piston plate and the locking block are made of magnets with opposite magnetic properties, and when the piston plate and the locking block are close to each other, they will generate an attraction to drive the locking block to move and disengage in the groove and engage with the rotating wheel.

[0013] Compared with existing technologies, the beneficial effects of this invention are as follows: The anti-fog lens of this visual suction tube, through its anti-scratch structure, effectively prevents the probe tube from scratching the uterine cavity wall tissue during operation. An air bladder is located on the outer wall of the probe tube near the opening. By pressing a rod to control the movement of the piston plate, air from the cavity is delivered into the air bladder, causing it to inflate and thus stretch and adhere to the uterine cavity wall tissue, keeping the opening away from the inner wall tissue. This design not only prevents the opening from sucking onto the inner wall tissue and causing abrasions when rotating the probe tube, but also provides protection when the probe tube is inserted into and withdrawn from the body, significantly reducing patient discomfort and potential risks during the examination.

[0014] Secondly, the rotating structure design greatly improves the ease of operation. By setting up a locking block that engages with the rotating wheel, and utilizing the attraction between opposite poles of magnetic materials, medical staff can easily disengage the locking block from the rotating wheel with a simple pressing operation, thereby enabling the probe tube to rotate freely. This design allows for adjustment of the lamp head, opening, and viewing lens angles without rotating the entire device, making single-handed operation more flexible and significantly improving the doctor's operating experience and work efficiency.

[0015] In addition, a reset spring and a locking spring are provided so that the pressing rod and the locking block can automatically reset after the operation is completed. This automatic reset function not only simplifies the operation steps, but also improves the stability and reliability of the device and reduces the risk of equipment failure due to improper operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This utility model provides a technical solution: a visual suction tube anti-fog lens, including a housing 1, a probe tube 2, a connecting tube 3, a lamp head 4, an opening 5, a visual lens 6, an anti-scratch structure 7, an airbag 701, a connecting tube 702, a support groove 703, a cavity 704, a piston plate 705, a pressing rod 706, a reset spring 707, a rotating structure 8, a rotating wheel 801, an installation port 802, a groove 803, a locking block 804, and a locking spring 805. The probe tube 2 and the connecting tube 3 are respectively installed on both sides of the housing 1. A lamp head 4 for illumination is installed at the end of the probe tube 2. An opening 5 is opened on the outer wall of the probe tube 2 near the lamp head 4. A visual lens 6 for easy observation of the uterine cavity is installed in the opening 5. An anti-scratch structure 7 is provided between the probe tube 2 and the housing 1 to prevent the probe tube 2 from scratching the inner wall of the uterine cavity. A rotating structure 8 is installed on the housing 1 for rotating and adjusting the probe tube 2 to change the viewing angle.

[0024] The end of the detector tube 2 near the lamp head 4 and the opening 5 is set at an angle, and the detector tube 2 and the housing 1 are rotatably connected.

[0025] The viewing lens 6 is installed at an angle inside the opening 5, and the viewing lens 6 is provided with a hydrophilic anti-fog coating.

[0026] The anti-scratch structure 7 includes an anti-scratch part and a control part. The anti-scratch part includes an airbag 701, a connecting pipe 702, a support groove 703, and a cavity 704. An airbag 701 is provided on the outer wall of the detection tube 2 near the opening 5. The airbag 701 is connected to the support groove 703 through the connecting pipe 702. The support groove 703 is connected to the cavity 704. Both the support groove 703 and the cavity 704 are opened inside the housing 1.

[0027] The control unit includes a piston plate 705, a pressing rod 706, and a return spring 707. The piston plate 705 is provided inside the cavity 704, and the bottom of the piston plate 705 is connected to the pressing rod 706. The end of the pressing rod 706 penetrates the bottom of the housing 1, and the pressing rod 706 is sleeved with a return spring 707. The two ends of the return spring 707 are respectively connected to the bottom of the cavity 704 and the bottom of the piston plate 705.

[0028] The rotating structure 8 includes a rotating wheel 801, a mounting port 802, a groove 803, a locking block 804, and a locking spring 805. The housing 1 has a mounting port 802 that extends through both ends of the housing. The rotating wheel 801 is installed in the mounting port 802 and is connected to the outer wall of the probe tube 2. The housing 1 has a groove 803 located in the area below the mounting port 802. The locking block 804 is connected in the groove 803. The locking spring 805 is connected between the locking block 804 and the groove 803. The end of the locking block 804 is engaged with the rotating wheel 801.

[0029] The piston plate 705 and the locking block 804 are made of magnets with opposite magnetic properties. When the piston plate 705 and the locking block 804 are close to each other, they will generate an attraction to drive the locking block 804 to move and disengage within the groove 803 and engage with the rotating wheel 801.

[0030] Working principle: According to Figure 1 As shown, in the working state, the locking spring 805 ensures that the end of the locking block 804 is tightly engaged with the rotating wheel 801, thereby limiting the rotation of the rotating wheel 801 and preventing the probe tube 2 from rotating freely in the non-operating state, thus avoiding affecting the performance. When it is necessary to adjust the orientation angle of the lamp head 4, opening 5, and viewing lens 6 on the probe tube 2, the medical staff presses the pressing rod 706 with their index finger, pushing the piston plate 705 into the cavity 704. At this time, the return spring 707 is stretched, and the air in the cavity 704 is transported to the airbag 701 through the support groove 703 and connecting pipe 702, causing the airbag 701 to inflate and expand to fit against the inner wall tissue of the patient's body. This process keeps the opening 5 away from the inner wall tissue of the patient's body, effectively preventing the opening 5 from sucking into the inner wall tissue during rotation and avoiding abrasions.

[0031] Meanwhile, the movement of the piston plate 705 within the cavity 704 brings it closer to the locking block 804. Since both the piston plate 705 and the locking block 804 are made of magnetic materials with opposite magnetic poles, the piston plate 705 magnetically attracts the locking block 804 into the groove 803, disengaging it from the rotating wheel 801. At this point, the locking spring 805 is compressed. Medical personnel can easily rotate the rotating wheel 801 with their thumb, thereby rotating the probe tube 2 and adjusting the angle of the opening 5 and the viewing lens 6. This design eliminates the need to rotate the entire device, making operation more convenient and faster. Furthermore, when the probe tube 2 is inserted into and withdrawn from the patient's body, the airbag 701 can also be inflated in the same way to prevent the probe tube 2 from scratching the patient's internal tissues.

[0032] When medical staff release the pressing lever 706, the elastic force of the reset spring 707 and the locking spring 805 causes the piston plate 705 and the locking block 804 to automatically reset. Through this ingenious design, the anti-fog lens of the visual suction tube can not only effectively prevent the probe tube 2 from causing damage to the patient's internal tissues during operation, but also allow for flexible adjustment of the angle of the probe tube 2, greatly improving the safety and convenience of hysteroscopy. This is the working principle of the anti-fog lens of the visual suction tube.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
