Background

Transvaginal surgery is an operation performed through the natural lacuna (vagina) of women and is widely used for diagnosis and treatment of gynecological diseases, such as cervical conization, transvaginal submucosal myoma excision, vaginal hysterectomy, hysteroscopy, gynecological pelvic floor operation, urogenital fistula repair, etc. The patient takes the bladder lithotomy position, the operation space between the two legs is small, the number and standing positions of operators are limited, and the vagina is of a cavity structure, so that the visible range is small, the operation difficulty is increased, and therefore, good exposure of the vagina and the cervix is particularly important for implementing the operation.

At present, the traditional vaginal dilator or the female retractor is mostly adopted clinically to expose the visual field.

The traditional vaginal dilator consists of five main parts, namely an upper leaf, a lower leaf, a handle, a nut a and a nut b, which are matched for use; the operator can put the vaginal dilator and move the handle to adjust the opening sizes of the upper leaf and the lower leaf, and then tighten the nut a and the nut b to fix after dilating the vagina and exposing the cervical satisfaction, and then the operation is performed. The conventional vaginal dilator has the disadvantages that:

(1) Only can expand the vagina to a limited extent, which is not beneficial to the operation of operators;

(2) The device cannot be fixed firmly, is easy to shift and slip, needs repeated resetting or assistant pressing fixation, brings great inconvenience to operation staff, and increases the risk of instrument pollution;

(3) The model is fixed, the adjustment can not be carried out according to individual differences of patients, such as the vaginal length and the vaginal wall elasticity degree, and the vaginal and cervical exposure is poor;

(4) The dependency on the assistant increases, resulting in waste of personnel and space.

The operation drawing using the female retractor is shown with reference to fig. 1, which has disadvantages in that: the female drag hook 1 is operated to give tension to draw by requiring 1-2 assistants to be positioned at the two sides of the patient, so that the smoothness of operation coordination is reduced due to incapability of seeing an operation field, the operation risk and operation duration are increased, meanwhile, the dependence on the assistants is increased, and the defect of personnel and space waste is caused.
