Description

Uterus traction device for obstetrics and gynecology department

Technical Field

The invention relates to the technical field of medical instruments, in particular to a uterus retractor for obstetrics and gynecology department.

Background

The gynaecology and obstetrics is one of four main subjects of clinical medicine, mainly researches the etiology, pathology, diagnosis and prevention of female reproductive organ diseases, physiological and pathological changes of pregnancy and delivery, prevention and treatment of high-risk pregnancy and dystocia, internal secretion in female reproduction, family planning, female health care and the like, deeply researches the medical basic theories of modern molecular biology, oncology, genetics, reproductive endocrinology, immunology and the like and advances of clinical medicine diagnosis and treatment detection technologies, widens and deepens the development of the gynaecology and obstetrics science, and plays an important role in guaranteeing the health of the women and the reproductive health and preventing and treating various gynecological diseases.

When carrying out the operation to the uterus, generally need to pull the uterus outside to convenient implementation operation, at present, present uterus puller adopts barb or barb mode to pull the uterus more, this kind of mode has the injury to the uterus, be unfavorable for patient's treatment, also make patient suffer more misery simultaneously, in the in-process that pulls out the uterus, pull out the uterus after being fixed in one or two points on the uterus with the puller often, cause to drop easily and pull repeatedly, it is great to the uterus injury, it is single to pull out the mode, and because the uterus is uncertain at human internal shape, in the in-process that will pull out ware and uterus fixed, be difficult for being fixed in the central point department of pulling in-process atress with the puller, the condition of tearing is caused because each position atress of uterus is inhomogeneous very easily in the in-process of pulling out, the uterus pulls out effect is relatively poor.

Disclosure of Invention

The invention aims to provide a uterus retractor for obstetrics and gynecology department, which aims to solve the problems that the prior uterus retractor in the background art mostly adopts a barb or barb mode to retract the uterus, the mode has damage to the uterus, is not beneficial to the treatment of the patient, causes more pain to the patient, in the process of drawing the uterus, the uterus is often drawn out after the drawing device is fixed at one or two points on the uterus, so that the uterus is easy to fall off and is repeatedly drawn, has great damage to the uterus, single drawing-out mode and uncertain shape of the uterus in the human body, in the process of fixing the retractor and the uterus, the retractor is not convenient to be fixed at the stressed central position in the pulling process, and the uterus is easy to be torn due to uneven stress of all parts of the uterus in the retracting process, so that the uterus retracting effect is poor.
