Problems solved by technology

However, because the uterus is not lifted, when the ligaments around the uterus have been severed, the uterine tissue has no traction and is difficult to move, which exposes the surgical field of view, resulting in significantly increased surgical difficulty and increased surgical complications.

Embodiment Construction

[0016] Combine below figure 1 , figure 2 and image 3 The present invention is described in detail, and the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not as a limitation to the present invention.

[0017] The invention provides a uterine traction device for laparoscopic hysterectomy, which includes a sleeve 1 that can extend into the puncture hole of the laparoscope, and a driving mechanism 2 and an elastic lasso 3 are arranged on the sleeve, and the driving mechanism drives the The elastic lasso moves axially along the sleeve, and the elastic lasso that moves out of the sleeve can be sleeved and fixed on the uterine body of the free part of the uterus. After part of the ligament beside the uterus is severed, the elastic lasso can be fixed on the free part of the uterine body. This structure can be retracted into the sleeve at the beginning of use, which is convenient for placing into the abdominal cavity...

Abstract

The invention relates to hysterectomy instruments, in particular to a uterine traction device for laparoscopic hysterectomy. The uterine traction device comprises a cannula that can be extended into alaparoscope puncture hole. The cannula is provided with a driving mechanism and an elastic rope. The driving mechanism drives the elastic rope to move along the axial direction of the cannula, and the elastic rope can be fixed to a uterine body on a free part of the uterine in a sleeved mode after being moved to extend out of the cannula. The uterine traction device has the advantages that the elastic rope can be fixed to the uterine body on the free part after a ligament of a parametrial part is broken, two ends of the elastic rope can be connected with traction lines extending from TROCAR holes of left and right lower abdomens, the uterine body is pulled by the traction lines to control the uterine to swing leftwards and rightwards, and the visual field of surgery is exposed, so that uterine lifting operations are avoided, difficulty of the surgery is reduced, and surgical complications are decreased.

Description

technical field [0001] The invention relates to an instrument for hysterectomy, in particular to a uterine traction device for laparoscopic hysterectomy. Background technique [0002] Hysterectomy is a common operation in gynecology, and it is the basic operation method to treat benign and malignant diseases of the uterus and even its adnexa. According to the QM classification, hysterectomy can be divided into simple hysterectomy (type A), less extensive hysterectomy (type B) and extensive hysterectomy (type C) due to the different extent of resection. Approaches include open hysterectomy, vaginal vaginal hysterectomy, laparoscopic hysterectomy, and vaginal-assisted laparoscopic hysterectomy. Among them, endoscopic and laparoscopic hysterectomy has been widely used clinically because of its advantages such as good surgical field of view, easy to master, less complications, less surgical injury, and quick postoperative recovery. [0003] In laparoscopic hysterectomy, in ord...
