Description
Technical Field
The utility model belongs to the technical field of medical operations, and relates to an opening device beneficial to sacrospinous ligament suspension operation.
Background
Pelvic organ prolapse (pelvic organ prolapse, POP) is an important medical problem, consuming enormous socioeconomic costs. It is estimated that over 50% of perimenopausal women are affected. The main therapeutic goal is to restore normal anatomy and thereby normalize pelvic organ function. Thus, the surgical strategy must be based on the location and severity of the pelvic floor defect. Given the variability of etiology, there is currently a need for a wider surgical scope and treatment modality to allow individualization of the treatment modality. Durability and good cost effectiveness are important factors in selecting the type of procedure. Although surgical approaches directed to central pelvic prolapse or dome prolapse are diverse, most repairs are still performed vaginally.
The common operation modes for clinically treating the pelvic defect comprise a Mann operation, a vaginal anterior-posterior wall repair operation, a vaginal sacral fixation operation, a sacrospinous ligament suspension operation, a high-order uterosacral ligament suspension operation, a full pelvic reconstruction operation and the like. In recent years, due to the problems of mesh erosion, exposure and the like, more and more clinical medicine selects a vaginal path through a natural cavity, wherein sacrospinous ligament suspension is one of classical pelvic floor reconstruction methods, and the clinical curative effect of the sacrospinous ligament suspension is widely focused. Classical Amreich-Richter technology sacrospinous ligament (sacrospinous ligament, SSL) can sometimes be technically challenging. The almrish-rish technique requires a wide and deep vaginal dissection in order to safely view and access the sacrospinous ligament (SSL). However, because of the deep anatomical site and the difficult transvaginal operation, the conventional operation method is to clamp the hymen edges on both sides of the back wall of the vagina, trim the skin at the hymen edges, and inject physiological saline under the mucosa of the back wall of the vagina as a water cushion, and fill 100ml. Cutting the central line of the back wall of the vagina, passively separating the gaps between the back wall of the vagina and the rectum and the right side wall to reach the right basin wall until the sacrospinous ligament is touched, exposing the sacrospinous ligament by two S-shaped drag hooks, enabling the left finger of an operator to touch and guide the ischial spines and the right sacrospinous ligament of the patient, suturing the 2 needle of the sacrospinous ligament 2.5cm away from the ischial spines by a 28mm round needle 1-0 silk thread, suturing the uterosacral ligament at the right stump, knotting, and then suturing the back wall mucous membrane of the vagina by a 1-0 micro arbor line continuous lock surface.
The key point of the operation is that the sacrospinous ligament is accurately exposed and found, but the patient with deep bone pelvic cavity and obesity is difficult to expose the sacrospinous ligament by using the conventional instrument because of the deep target anatomical position, and the operation difficulty and operation time are increased by using the conventional instrument.
