Description

Vaginal dilator for operation examination and use method thereof Technical Field The invention relates to the technical field of medical instruments, in particular to a vaginal dilator for surgical inspection and a use method thereof. Background The vaginal dilator is a medical instrument for gynecological examination, treatment and rehabilitation training, and has the core effects of gently dilating vaginal cavity, creating vision for diagnosis and treatment operation or helping to improve the problem of vaginal stenosis. The design of the gynecological examination device is based on an ergonomic principle, and the device is generally composed of an upper expansion piece, a lower expansion piece and an adjusting handle, wherein the opening and closing angle of the expansion pieces is controlled through the handle, so that the expansion degree can be accurately adjusted according to requirements, discomfort in use is reduced, and the device is a basic instrument for gynecological examination on a suitable scene, can assist doctors to observe the conditions of vagina and cervix, and is used for carrying out operations such as secretion sampling and cervical screening, and is also used for rehabilitation treatment of the conditions such as postpartum vaginal relaxation and vaginal stenosis after gynecological operation, and is helpful for recovering the elasticity and width of the vagina. The use is carried out under the guidance of the profession, the sterile operation standard is followed, the rehabilitation training products are matched with the lubricant, the size is gradually adjusted according to the personal tolerance, and the safety and the effectiveness are ensured. But the upper leaf and the lower She Duowei rigid structure of current expander, and expansion angle and scope regulation flexibility are relatively poor, be difficult to carry out accurate adaptation according to different patient's vagina physiological structures, lead to the fact extrusion damage to patient's vagina mucosa easily, increase patient's painful sense and uncomfortable sense, in the operation inspection in-process, need additionally operate with the help of lighting apparatus and auxiliary instrument such as tweezers, curet etc. moreover, current expander lacks the adaptation structure that corresponds, lead to mutual interference between the apparatus, operating space is restricted, influence the efficiency and the accuracy of operation inspection, in addition, partial expander's adjustment mechanism stability is not enough, take place not hard up easily under the expansion state, can't keep stable expansion field of vision, bring the potential safety hazard for the operation. Disclosure of Invention Aiming at the defects of the prior art, the invention provides a vaginal dilator for operation examination and a use method thereof, which solve the problems that the upper leaf and the lower She Duowei of the existing dilator are of rigid structures, the expansion angle and the range are poor in adjustment flexibility, the vaginal mucosa of different patients is difficult to accurately adapt according to the vaginal physiological structures of the different patients, the vaginal mucosa of the patients is easy to be extruded and damaged, the pain and discomfort of the patients are increased, in the operation examination process, the operation is required to be additionally carried out by means of illumination equipment and auxiliary equipment such as forceps, curettes and the like, the existing dilator lacks corresponding adaptation structures, the mutual interference among the equipment is caused, the operation space is limited, the efficiency and the accuracy of the operation examination are influenced, in addition, the stability of an adjusting mechanism of a part of the dilator is insufficient, the expansion angle and the range are easy to loose under the expansion state, the stable expansion view is not maintained, and the hidden danger is brought to the operation. The electric bicycle comprises a handle and a positioning mechanism, wherein the outer surface of the handle is connected with a lower expansion plate, the upper surface of the lower expansion plate is connected with two fixing plates, one side surface of each fixing plate, which is close to the other side surface, is connected with a rotating shaft through a bearing, one end of each rotating shaft, which is close to the other side surface, is connected with an ear plate, the upper surfaces of the two ear plates are connected with an upper expansion plate together, the inner wall of the lower expansion plate is connected with a lamp holder, the upper surface of the lamp holder is provided with lamp beads which are arranged at equal intervals, the bottom surface of the handle is provided with a charging port, the left side surface of the handle is provided with a cavity, the inner bottom wall of the cavity is connected with a protection pad, the upper surface of
