Description

Telescopic duckbilled fetching clamp

Technical Field

The utility model belongs to the technical field of tumour apparatus is got to peritoneoscope hysteromyoma, in particular to thing pincers are got to telescopic duckbilled.

Background

The hysteromyoma is a benign tumor formed by hyperplasia of uterine smooth muscle tissues, is the most common benign tumor of women, and the prevalence rate of women in the childbearing age can reach 25%. The clinical manifestations mainly relate to the growth position and speed of tumor and whether degeneration occurs, the main clinical manifestations include menorrhagia, menostaxis, leukorrhagia, lower abdomen mass, infertility, etc., when the tumor is large, the rectum, bladder, ureter are pressed, and the pressing symptoms of corresponding organs such as frequent micturition, constipation, etc. can be caused. The hysteromyoma is the most common benign tumor in gynecology, and is better developed in a female with a growth period of 25-40 years old, so that the hysteromyoma removing operation with a growth function retained is mostly needed, at present, clinical operation ways comprise 3 types of abdominal, laparoscopic and vaginal operations, and the laparoscopic hysteromyoma removing operation becomes the choice of most patients along with the development of minimally invasive technology.

Hysteromyoma enucleation (LM) under laparoscope has the advantages of small wound, quick recovery, small postoperative scar and the like, and is the first choice treatment method for most women at present. Present tumour technical scheme of getting need take out through the belly sleeve after for the enucleation myoma under the peritoneoscope, if the sample volume is great then need cut into the fritter progressively consuming time and take out. Electronic hysteromyoma grinder is an energy apparatus with tubulose blade, is furnished with the nipper and grasps fixed tissue sample, and electric energy drive blade is high-speed rotatory behind the switch on, by this cuts into the fritter with tissue sample, takes out smoothly through the belly puncture opening after the reduction volume.

The principle of myoma morcellator is determined in benign disease, but the morcellation risks the formation of parasitic tumors. And according to the united states Food and Drug Administration (FDA) analysis, approximately 1 patient was found to have cryptogenic uterine sarcoma, which is less common clinically, but highly malignant and poorly prognostic, per 350 cases of hysterectomy or hysterectomy. The crushing tool used in the minimally invasive surgery can disperse the tumor tissues in the pelvis and the abdomen, so that the tumor cells are scattered, and the survival chance of a patient is greatly reduced. The FDA issued safety notices in 2014 without advising physicians laparoscopically to perform hysteromyoma morcellations, after which laparoscopic hysteromyoma enucleations declined worldwide.

This kind of electronic myoma grinder commonly used in the existing market is in the use, because high-speed rotation uses the sharp nature to cut apart the cutting and reduces the myoma volume gradually to there is certain broken risk of loosing of thing of smashing in the operation mode that can follow peritoneoscope passageway (Trocar) and take out, brings the shortcoming that the tumour scatters easily, so use electronic myoma grinder to get the abdominal cavity disseminated hysteromyoma scheduling problem that the tumour leads to easily under the peritoneoscope, make peritoneoscope hysteromyoma rejection art receive very big restriction.
