Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a guide device that is arranged in gynaecology's operation to judge vagina length.

Background

In gynecological surgery, guidance on the length of the vagina is often required. Taking the cervical cancer operation as an example, clinically, the surgical treatment of the cervical cancer is to complete surgical excision of different ranges according to different stages, for example, the IA2 cervical cancer is subjected to repeated extensive hysterectomy, and the length of vaginal excision is required to be 2cm; extensive hysterectomy is carried out on the IB 1-stage cervical cancer, and the length of colpectomy is required to be 3cm; for patients with vaginal lesions such as cancer focus and precancerous lesion, the vagina with enough length is required to be cut off to ensure that no focus exists at the incisal margin. For the above situations, the surgeon needs to judge the vaginal length timely and accurately during the operation to determine the surgical resection range. At present, the position of a vaginal lesion can only be judged before an operation clinically, the vaginal resection with a certain length is carried out according to clinical experience in the operation, and whether the lesion is resected or not and whether the resection range is enough are judged by looking at a specimen after the resection. If the resection range is found to be insufficient, supplementary resection is continued, important organs such as the bladder and the ureter need to be pushed down again during supplementary resection, and the uterus is resected at the moment, so that traction caused by the uterus is lost, and the risks of bleeding in the operation and damage to adjacent organs such as the bladder and the ureter are increased; if the length of the excision is too long, no remedial measures are taken, and the operation can only be completed, and the excision too much influences the later quality of life of the patient, such as sexual life.
