Description

Technical Field

[0001] The invention relates to the technical field of urology auxiliary equipment, and in particular to a urology minimally invasive surgery positioning device. Background Art

[0002] Minimally invasive surgery does not require opening the cavity. It only requires 1-3 small holes of 0.5-1 cm to be made on the patient. The patient will not be left with scars, and the entire process of examination, treatment, and rehabilitation can be completed in 3-5 days. It reduces the harm of traditional surgery to the human body and greatly reduces the inconvenience and pain of patients. Female stress urinary incontinence is a common disease in urology. Factors such as childbirth injuries, premature weight bearing after childbirth, impaired pelvic floor support tissue function, and postmenopausal estrogen and androgen deficiency can cause weakness of the support tissue at the junction of the urethra and bladder and decreased urethral smooth muscle tension, thereby causing or aggravating stress urinary incontinence.

[0003] The current mainstream minimally invasive surgery for treating urinary incontinence is mainly the transobturator transvaginal mid-urethral sling surgery, which has a definite effect. The surgery supports the mid-urethra by implanting a tension-free mesh sling, and achieves the purpose of urine control by strengthening the support force of the mid-urethra. The general process is to puncture the sling with a puncture device and hang it under the urethra, make another small incision in the vagina, and the puncture needle enters the body through the incision in the vagina, and comes out from an incision in the groin area, pulling the mesh belt connected to the puncture needle along the path, and then the puncture needle connected to the mesh belt on the other side drives the puncture needle at the other end of the mesh belt to repeat the above operation.

[0004] In order to facilitate the expansion of the patient's vagina in the above-mentioned minimally invasive surgery, a Chinese patent with application number CN202410083890.0 discloses a urology minimally invasive surgery positioning device. The urology minimally invasive surgery positioning device includes a half-tube, a detachable hollow head is installed at one end of the half-tube, the end of the hollow head away from the half-tube is a smooth arc surface structure, the other end of the half-tube is bent outward to form a curved portion, and the end of the curved portion away from the half-tube is fixedly connected to a storage tube for collecting waste liquid, and the end of the hollow head close to the half-tube is installed with a plurality of detachable elastic expansion sheets for expanding the vagina; and also includes a support assembly, which is connected to the half-tube and is used to support the plurality of elastic expansion sheets.

[0005] When in use, after the half tube, the hollow head and a number of elastic expansion sheets are inserted into the vagina, the several elastic expansion sheets are squeezed and deformed, causing the vagina to expand. By rotating the rotating ring, when the rotating ring moves inward, it also drives the moving ring to move inward. The moving ring drives the limit slider to move in the limit groove through the connecting rod, and multiple limit sliders move synchronously, thereby achieving the purpose of expanding or reducing the diameter of the fixed ring; the adjustment of the rotating ring in the above-mentioned adjustment process is manual, and manual adjustment has the problems of low efficiency and low precision; and the height and angle of the above-mentioned urological minimally invasive surgical positioning device are fixed during the adjustment process, which cannot meet the patient's body position requirements.
