Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a vaginal speculum for surgical examination and its method of use. Background Technology

[0002] A vaginal speculum is a medical device used for gynecological examinations, treatments, and rehabilitation training. Its core function is to gently dilate the vaginal cavity, creating a field of vision for diagnostic procedures or helping to improve vaginal stenosis. Designed according to ergonomic principles, it typically consists of two dilating blades and an adjustable handle. The handle controls the opening and closing angle of the dilating blades, allowing for precise adjustment of the dilation degree as needed, reducing discomfort during use. In practical applications, it serves as a basic instrument for gynecological examinations, assisting doctors in observing the vagina and cervix, performing procedures such as secretion sampling and cervical screening. It is also commonly used in the rehabilitation treatment of postpartum vaginal laxity and post-gynecological surgery vaginal stenosis, helping to restore vaginal elasticity and width. Use must be under professional guidance, following aseptic operating procedures. Rehabilitation training products require the use of lubricant, and the size should be gradually adjusted according to individual tolerance to ensure safety and effectiveness.

[0003] However, the upper and lower blades of existing dilators are mostly rigid structures, and their adjustment flexibility in terms of dilation angle and range is poor. It is difficult to accurately adapt them to the different vaginal physiological structures of different patients, which can easily cause compression damage to the vaginal mucosa, increasing the patient's pain and discomfort. Moreover, during the surgical examination, additional lighting equipment and auxiliary instruments such as forceps and curettes are required for operation. The lack of corresponding adaptation structures for existing dilators leads to mutual interference between instruments, limited operating space, and affects the efficiency and accuracy of the surgical examination. In addition, the adjustment mechanism of some dilators is not stable enough and is prone to loosening in the dilation state, making it impossible to maintain a stable dilation field of view and posing a safety hazard to the surgical operation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a vaginal speculum for surgical examination and its usage method. It solves the problems of existing speculum's upper and lower blades being mostly rigid structures with poor flexibility in adjusting the expansion angle and range, making it difficult to accurately adapt to different patients' vaginal physiological structures. This can easily cause compression damage to the vaginal mucosa, increasing patient pain and discomfort. Furthermore, during surgical examinations, additional lighting equipment and auxiliary instruments such as forceps and curettes are required, and existing speculum lacks corresponding adaptable structures, leading to interference between instruments, limited operating space, and affecting the efficiency and accuracy of surgical examinations. In addition, the adjustment mechanism of some speculum lacks stability and is prone to loosening during expansion, making it impossible to maintain a stable expansion field of view and posing safety hazards to the surgical procedure.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a grip and a positioning mechanism are included. A lower expansion plate is connected to the outer surface of the grip. Two fixed plates are connected to the upper surface of the lower expansion plate. A rotating shaft is connected to one of the two fixed plates on their adjacent sides via bearings. Ear plates are connected to the adjacent ends of the two rotating shafts. An upper expansion plate is connected to the upper surface of the two ear plates. A lamp holder is connected to the inner wall of the lower expansion plate. LED beads arranged at equal intervals are mounted on the upper surface of the lamp holder. A charging port is opened on the bottom surface of the grip. The grip has a cavity on its left side, a protective pad on the inner bottom wall of the cavity, a battery mounted on the upper surface of the protective pad, a transparent plate on the inner wall of the lower expansion plate, two control switches on the outer surface of the grip, a positioning mechanism including a connecting plate, a limit plate on the bottom surface of the connecting plate, a sliding hole on the upper surface of the limit plate, a sliding rod slidably connected inside the sliding hole, a handle on the upper surface of the sliding rod, a circular plate on the bottom surface of the sliding rod, and a plug on the bottom surface of the circular plate.
