A bagged hysterectomy device

Abstract

The invention relates to a novel bag covering hysterectomy device. The novel bag covering hysterectomy device comprises optical tweezers, a scalpel tube and an endoscope. The optical tweezers are arranged in the scalpel tube, and a positioning sleeve and the scalpel tube are connected with each other and arranged in a protection sleeve together. The scalpel tube is connected to the driving end of a manual motor shank, and an expansion ring sleeves the outer wall of the scalpel tube and is arranged between the protection sleeve and the driving end of the manual motor shank. The endoscope is communicated with the optical tweezers and fixed to the non-driving end of the manual motor shank, and the manual motor shank provides the required power through a motor. One end of the expansion ring is fixed to the outside of an abdominal cavity, and the other end is fixed to the inside of the abdominal cavity and connected to a specimen bag for forming a surgical channel between the specimen bag and the outside. The novel bag covering hysterectomy device has the advantages that a uterus is separated from the body, the specimen bag is placed in the abdominal cavity to place the separated tissue into the bag through the surgical channel formed by the device, and the excised tissue is pulled out of the abdominal cavity through an opening fixed to the abdominal cavity to prevent the tissue from metastasizing and the infection proneness in a hysterectomy process.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a bagged hysterectomy device suitable for a specimen bag operation method. Background technique [0002] With the widespread use of the electric hysterectomy device (hereinafter referred to as the resection device), more and thousands of women benefit from uterine-preserving operations, such as myomectomy. Morcellation makes this possible in order to provide patients with more minimally invasive procedures that often require removal of large tissue samples through small incisions. Morcellation encompasses a number of surgical techniques by which large specimens can be removed from the abdominal cavity, thereby avoiding laparotomy. [0003] However, with the widespread use of the resectator, the insufficient resection has also been exposed. [0004] 1. Injuries to internal organs (intestines, genitourinary organs, others) and large blood vessels caused by forceps or ...

Problems solved by technology

[0003] However, with the widespread use of the resectator, the insufficient resection has also been exposed.

[0004] 1. Injuries to internal organs (intestines, genitourinary organs, others) and large blood vessels caused by forceps or blades have been reported, some of which even resulted in death of patients

[0005] 2. The trouble with morcellation is that with our diagnostic techniques and tools, not all uterine malignancies can be identified in the preoperative evaluation

[0006] Neither preoperative examination could identify leiomyoma nor intraoperative washing could not ensure thorough morcellation resulting in fragments resulting in postoperative iatrogenic dissemination

For this reason, the existing resectator is not suitable for crushing directly in the abdominal cavity
