Description

Hysteromyoma removing crowbar

Technical Field

The utility model relates to the technical field of auxiliary medical equipment, in particular to bar is rejected to uterus myoma.

Background

Hysteromyoma is the most common benign tumor in female reproductive organs and is one of the most common tumors in human bodies, is common in women of 30-50 years old, and has the incidence rate of 50-70%. With the increasing level of clinical treatment, preserving fertility and minimizing trauma has become the greatest concern for clinicians and patients.

The common treatment methods of the hysteromyoma comprise drug treatment, operation treatment and focused ultrasound treatment. The hysteromyoma removing operation can not only keep the fertility of a patient, but also maintain the physiological function of the uterus, keep the integrity of the pelvic floor anatomical structure, has the minimum influence on the hypothalamus-pituitary-ovary-uterine axis, is beneficial to the physical and psychological health of the patient, and is a preferred and conventional treatment method for the hysteromyoma.

Laparoscopic surgery is an instrument-dependent surgery, and surgical instruments used in the hysteromyoma removal surgery under the laparoscope at present comprise a high-frequency electric knife, a tissue scissors, a myoma drill and an ultrasonic knife. The high-frequency electrotome is most widely applied, including single-pole and double-pole electrocoagulation, the core of the working mechanism is that electrocoagulation and electrotomy are carried out by utilizing the heat damage effect generated by current passing through a body, but a large amount of smoke is generated in the using process to cause the fuzzy operation visual field, smoke needs to be continuously discharged, so that the operation time is prolonged, in addition, the smoke contains a large amount of toxic gases, mainly comprises carbon monoxide, hydrogen cyanide, acrylonitrile, benzene and the like, the heat effect is obvious, high heat of 100-400 ℃ is generated, the tissue around 15mm can be damaged, the electrical injury is easy to occur, particularly, the adjacent muscular layer tissue can be damaged, the tissue healing is influenced, particularly, for the non-nurses and the people with fertility requirements, the uterine rupture can occur when the pregnancy is carried out again. The tissue scissors are also a common surgical instrument for removing myoma, but the tissue scissors can only take out the myoma tissue a little bit, and the operation is long in time consumption and high in cost. The front end of the myoma drill is easy to break when in use, and the myoma with the diameter of more than 6cm is difficult to take out and takes time. The ultrasonic scalpel only generates small water drops without generating smoke in the using process, has clear operation visual field, small thermal damage and no electric damage, but has high price, slow operation in the operation, can only cut and coagulate tissues which are contacted with the ultrasonic scalpel and have certain tension, can not cut too many tissues each time, and is long in operation time.
