Description

Uterine manipulator without guide rod

Technical Field

The utility model relates to the technical field of medical supplies, in particular to a uterine manipulator without a guide rod.

Background

The total hysterectomy is the most common operation mode in gynecology, and most patients need the total hysterectomy due to uterine diseases. Commonly used approaches to hysterectomy include: transvaginal, laparoscopic and abdominal surgery, with transvaginal and laparoscopic surgery being referred to as "minimally invasive surgery". However, the laparoscopic surgery has a narrow operation space and more operation limitations, and in order to reduce surgical risks and ensure the success rate and the effect of the surgery, the position of the uterus needs to be adjusted to a position convenient for resection before resection and fixed; the cup type uterine elevator is a most common operation matched instrument for laparoscopic total hysterectomy, and the uterine cup is lifted to enable the fornix vaginae to be higher than the ureter level, so that the ureter is prevented from being damaged;

the uterus lifter can lead the uterus to swing towards all directions in the laparoscopic surgery and fully expose the fornix part of the vagina, thereby exposing the surgical visual field to the maximum extent, being beneficial to the surgical operation and reducing the surgical complications. The cup type uterus lifter commonly used in clinic mainly comprises a central guide rod, a cervix fixer and a fornix cup. The defect of the uterine manipulator is that postmenopausal women can not use the common uterine manipulator for auxiliary operation due to the failure of placing the guide rod caused by cervical atrophy and adhesion; and because the surrounding vaginal wall is close to the middle, the boundary between the cervix and the vaginal wall is unclear, and the cervix is difficult to clamp and cannot be pulled, so that surrounding tissues and organs are easily damaged by the operation. Meanwhile, the uterine manipulator presses the vagina downwards to achieve the effects of pressing and lifting through the lever principle, so that the vagina is possibly seriously damaged, manual force is required to be applied in the whole process to keep the uterine manipulator, the stability is low, the operation risk is increased, and the injury to a patient is deepened;

therefore, the uterine manipulator without the guide rod has important significance and practical value.
