Description

three-cavity water injection laparoscope sheath

Technical Field

The utility model relates to the field of medical equipment, relate to three chamber water injection peritoneoscope mirror sheaths particularly.

Background

With the development of social economy, women continuously postpone the birth age, the increase of social pressure, environmental pollution, increase of sexually transmitted diseases and other reasons, and the incidence rate of infertility tends to rise. According to the crowd sampling survey, the infertility accounts for about 10-15% of that of couples in the childbearing age. Common female infertility causes include endometriosis, fallopian tube factors, polycystic ovarian syndrome, chronic pelvic inflammation and the like. Clinically, the patency of the oviduct is evaluated by hysterosalpingography usually, but the sensitivity and the specificity are lower. The combined examination of laparoscope and hysteroscope can define the cause of infertility and perform surgical treatment at the same time. However, when used for infertility examination via laparoscopy, about 41% to 70% of patients have no positive findings or only mild lesions in their pelvic cavities. The pneumoperitoneum laparoscope requires general anesthesia of a tracheal cannula, has high medical cost and also has certain operation risks. The transvaginal laparoscope (THL) is a minimally invasive endoscope technology which adopts a puncture cannula to puncture into a pelvic cavity through the fornix behind the vagina, takes physiological liquid (physiological saline and ringer's solution) as a pelvic cavity expansion medium, and carries out diagnosis and treatment by means of a miniature endoscope and an instrument. The THL is a natural cavity endoscopic operation, has the advantage of accurate evaluation, and also has the advantages of minimal invasion, no general anesthesia, outpatient operation, good patient tolerance and the like. Meanwhile, as the THL swelling medium is liquid, pelvic cavity organs float in the liquid, fine and thin pelvic cavity adhesion can be easily found, and the method is particularly suitable for finding slight adhesion of the umbrella end of the fallopian tube. Besides being used as an effective examination means for patients with infertility, the THL can also complete simple operation treatment including pelvic adhesion release, ovarian perforation, endometriotic focus removal and the like while examination, and has unique advantages for the examination and treatment of patients with infertility.

At present, the surgical instruments used for the transvaginal water laparoscope are limited, the achievable surgical operation is limited, and the clinical popularization and application of the surgical method are seriously limited. The transvaginal laparoscope which is widely applied in clinic is manufactured by STORZ company, and the surgical instruments comprise a puncture outfit, an expansion sheath, an examination sheath and a surgical sheath, and are matched with operating instruments such as biopsy forceps, scissors, grasping forceps, bipolar electrodes and the like. The main surgical instrument is formed by combining an endoscope and a surgical sheath, is punctured into an abdominal cavity through a vaginal posterior fornix under the assistance of a puncture device and the like, and is put into an operating instrument through an operating hole of the surgical sheath to finish simple operations of clamping, electrocoagulation and the like. However, the current surgical sheath only has one surgical operation hole, and only one surgical operation instrument can be placed at a time. The surgical instruments need to be frequently replaced during the surgical process. In relatively complex surgery, when tissue needs to be exposed by traction and the surgical operation is completed, the single instrument operation hole can limit the surgical range, reduce the surgical satisfaction and increase the surgical operation risk. For example, in transvaginal laparoscopic ovarian perforation, the ovary needs to be pulled to be exposed and fixed, when the ovary is kept away from the ovarian portal and the position of an important blood vessel, the ovary surface is perforated by bipolar or laser, and under the condition of lack of auxiliary exposure of instruments, the plane of the ovary is difficult to expose, the operation effect is poor, the position of the ovary in the perforation can move, and the operation difficulty and the risk of occurrence of complications are increased.

SUMMERY OF THE UTILITY MODEL

to the problem in the correlation technique, the utility model provides a three chamber water injection peritoneoscope mirror sheaths, can place two operation apparatus simultaneously, operation nipper is used in the cooperation, operation apparatus such as bipolar coagulation needle, in the operation in-process, the operator places the nipper through an apparatus channel pipe, fixed tissue organ, fully expose, simultaneously place electric coagulation needle or other operation apparatus through another apparatus channel pipe, accomplish required operation such as electric coagulation hemostasis, the area excision of adhesion, ovary punching etc., can obtain more satisfied operation effect, improve operation safety, avoid the tradition to need frequently to change the not enough of operation apparatus through vagina water peritoneoscope.
