Description

Uterus lifting device for gynecological clinical operation

Technical Field

The utility model relates to the technical field of surgical instruments, in particular to a uterus lifting device for gynecological clinical operation.

Background

Cervical cancer is the fourth leading malignancy incidence in women, with about 604000 new cases each year and about 342000 deaths worldwide. Compared with open surgery, more researches in the past prove that the laparoscopic surgery has the advantages of clear anatomical hierarchy, less bleeding in surgery, less pain of patients, short hospitalization time after surgery and the like, and the safety and the effectiveness of the laparoscopic surgery have no statistical significance with the difference of the open surgery. Early cervical cancer radical treatment by laparoscope has become the first choice for doctors and patients. Two articles published in the new england medical journal at 10 of 2018 show that laparoscopic cervical cancer radical surgery has a higher recurrence rate and a lower tumor-free survival rate compared to open surgery. Experts at home and abroad consider that: the uterine lifting rod possibly using the uterine lifting device in the laparoscopic surgery directly passes through the cervical cancer stove and the uterine lifting cup has extrusion function; CO ₂ The subpneumoperitoneum breaks off the vagina and the broken end causes the spreading of tumors; the pelvic lymph nodes excised in the operation are directly exposed in the abdominal cavity; finally, the posterior end of the circular cutting vagina is directly exposed to the pelvic cavity. Thus, clinicians want to avoid lifting the uterus using various methods: if the uterus bottom is sutured or the two sides of the uterus ligament are sutured, the uterus is swung left and right or lifted up through the abdomen, so that the uterus is vertical, thereby facilitating the operation.

During the operation, some operators currently use needle holders to clamp sutures to lift the uterus, swing the uterus side to side, push the uterus forward or make the uterus vertical. Because the needle holder is adopted for operation, the following defects are caused: 1. the needle holder is a relatively precise instrument, is clamped for a long time and is easy to damage; 2. the needle holder cannot be folded at the top end, so that the uterine mobility is limited, and the needle holder must be pressed down in order to reach the exposed state. Such accelerated instrument damage, and instead, poor surgical field exposure; 3. the needle holder is not easy to fix outside the body; 4. the needle holder is relatively long, so that the mobility in vitro is limited, and the needle holder is clumsy.

However, the uterus lifting device of the 'Ding Shi' currently has the following defects: 1. the material is soft, and is easy to deform in the use process, so that the uterine lifting effect is affected; 2. the fixing hole is smaller, the operation in the laparoscope is relatively inconvenient, and longer time is required for operation; 3. the handle is flat, so that the operator is difficult to hold when operating the surgical assistant, the operator has strong discomfort, and as the operation is performed and the time is advanced, the doctor can feel palm pain and discomfort in a short time, and the health of the doctor is influenced; 4. the device cannot be fixed in vitro, and an assistant is required to continuously hold the holding posture by hand in the whole operation process, so that the discomfort of a doctor is more serious.
