Problems solved by technology

[0003] In traditional laparoscopic total hysterectomy, in the surgical procedure, in the process of resection of the uterine body, the blood vessels or cervical canal ferrule are usually sutured, and the uterus is crushed into strips with a rotary cutter and taken out. There are two Disadvantages: First, tissue loss is likely to occur during the rotary cutting process, and if it is a malignant disease, the tumor stage is prone to increase
Second, the incision margin of the cervical stump is not neat and uneven, which needs to be trimmed with scissors, and the operation time is long

Embodiment 1

[0034] A hysterectomy device, comprising a hollow protective cannula 1, an operating rod 2 inserted in the protective cannula and drawn along the protective cannula, and a ring connected to the front end of the operating rod for wrapping around the uterus The stretching and shrinking wire ring 3 is elastic and at least partially arc-shaped and can cut the uterus; the rear end of the stretching and shrinking wire ring is connected to the front end of the operating rod.

[0035] The front end of the stretching and shrinking ring is an arc segment 4 for removing the uterus, and an insulated wire segment 5 covered with an insulating sleeve is formed from both ends of the arc segment to the front end of the operating rod. The distances from both ends of the arc segment to the front end of the operating rod are equal.

[0036] The protective cannula is inserted into the abdominal cavity and after the front end of the cannula is delivered to the desired position, the handle at the re...

Embodiment 2

[0038] The difference from the above embodiment is that the stretching and shrinking wire ring is a whole exposed arc line. The power can be turned on to cut when the stretching and shrinking wire ring is tightening the cervix, which can ensure that other tissues are not damaged.

Embodiment 3

[0040] The difference from the above embodiment is that the resectator also includes an isolation extraction bag 6 that is sleeved and connected to the insulated wire segment to enclose the uterus. The rod can be retracted into the protection intubation while pulling back along the protection intubation. During the design, the mouth of the isolation picking bag can be larger than the ring diameter of the stretching and shrinking wire ring, which is convenient for protecting the picking bag.

[0041] When the stretching and shrinking wire ring is put on the cervix of the uterus, the uterus is also put into the isolation extraction bag. The setting of the isolation extraction bag ensures that the excised uterus is fully enclosed, which is not only convenient for the later smashing and removal of the uterus, but also Effectively prevent the tissue from falling and completely remove the patient. In the later stage, the mouth of the isolation extraction bag can be tightened and pu...

Abstract

The invention relates to the field of medical instruments, in particular to a uterus excising instrument.The uterus excising instrument comprises a hollow protective cannula, an operating rod which is inserted into the protective cannula and can be drawn along the protective cannula and a stretchable line ring, the stretchable line ring is connected to the front end of the operating rod and used for being arranged on the uterus in a sleeving mode and excising the uterus and has the elasticity, at least part of the stretchable line ring is provided with an electric arc line, and the back end of the stretchable line ring is connected to the front end of the operating rod.The laparoscopic uterus excising instrument can be operated by one surgeon, a uterus body is completely excised at a time through a conventional energy platform, time is short, and an incision is neat without needing to be trimmed.The power of electric arcs is adjustable and controllable, and the peripheral tissue is protected by arranging an insulated wire section and / or an insulated line section to prevent electric injuries from being generated.The excised uterus body is directly put in an isolation removing bag, and therefore a tumor infection risk is avoided.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a hysterectomy device. Background technique [0002] Subtotal hysterectomy is used to treat gynecological diseases such as uterine fibroids, uterine dysfunctional bleeding, adenomyosis and other gynecological diseases with normal cervical examination, or the hysterectomy is required for various reasons, but the removal of the cervix is ​​helpful. Difficult ones. Hysterectomy now has laparotomy, vaginal and laparoscopic operations, the latter two are minimally invasive surgery. Compared with laparoscopic subtotal hysterectomy, due to its small incision, laparoscopic surgery has lower postoperative complications, fewer opportunities for postoperative analgesia, and faster return to normal work and life. The laparoscopic incision is small, which is more beneficial to obese patients. The visual field is clear during the operation, and the problem of poor healing caused by large abd...
