In a method for determining the pelvic inlet plane of the pelvic bone, which is defined by the following three points of the pelvic bone:point A: spina iliaca anterior superior leftpoint B: spina iliaca anterior superior rightpoint C: symphysis pubis,by non-invasive determination of the position of one of the two points A or B and point C, in order to also be able to carry out this determination whenever point A or point B is not accessible, it is proposed that the position of the following points of the pelvic bone be additionally determined non-invasively:point D: spina iliaca posterior superior leftpoint E: spina iliaca posterior superior right,and that the position of the pelvic inlet plane be calculated from the position of the non-invasively determined points A or B, C, D and E.

Positioning an acetabular cup in a desired optimal alignment in relation to the patients pelvis using conventional fluoroscopic equipment readily available in operating rooms in conjunction with a metallic jig as guide. The device having inclination metallic rods at 45 degrees angle to the cup impactor and anteversion rod situated at a distance from the midline that correspond to the degree of inclination. When said inclination and anteversion shafts are aligned with central anatomical structures such as symphysis pubis and middle of first sacral vertebra will result in correct placement of the acetabular cup at the desired version.

The present invention provides a device (1) for patient body positioning and immobilizing has four pressing pieces (41-44) for immobilizing the lumbar region of a patient (P) in lateral decubitus position on a table (B). The first pressing piece (41) and the second pressing piece (42) are arranged in a position corresponding to the anterior superior iliac spine (AS) of the patient (P). The third pressing piece (43) is arranged in a position corresponding to the pubic symphysis (PS) of the patient (P). The fourth pressing piece (44) pushes against the back surface of the lumbar region of the patient (P). The plane (P2) containing each of the pressing planes (F1-F3) of the first, second and third pressing pieces (41-43) is parallel to the patient (P)'s pelvic floor reference plane (P1). An angle indicator (6) is attached to a stand (30) supporting the first, second and third pressing pieces (41-43). The angle indicator (6) has an indicating rod (63). A first angle ([Theta]1) and a secondangle ([Theta]2) specifying the orientation of the indicating rod (63) with respect to the pelvic floor reference plane (P1) can be each regulated with a first angle regulator (61) and a second angleregulator (62). During a hip replacement arthroplasty, a rod (R) of a surgical instrument (OT) is held parallel with the indicating rod (63), and a cup (CP) is inserted in the patient (P)'s acetabulum using the surgical instrument (OT).

A method for alleviating female urinary incontinence especially during episodes of increased intra-abdominal pressure is disclosed. The method includes the steps of providing a non-absorbent urinary incontinence device having an initial cross-sectional area, an insertion end and a trailing end. The urinary incontinence device also contains a compressed resilient member which is capable of increasing the cross-section area of the urinary incontinence device when expanded. The urinary incontinence device is inserted into a woman's vagina with the insertion end entering first. The vagina is a canal with an inner periphery made up of right and left lateral walls, an anterior wall and a posterior wall. The urinary incontinence device is inserted such that it contacts at least two of the walls. The urinary incontinence device is positioned in the middle third of the length of the vaginal canal with the insertion end aligned adjacent to a woman's urethral sphincter muscle. The urethral sphincter muscle is a part of the urethral tube. The urinary incontinence device cooperates with a woman's symphysis pubis to sandwich the urethral tube therebetween. The resilient member is allowed to expand within the vaginal canal such that at least a portion of the urinary incontinence device increases in cross-sectional area and contacts all four interior walls of the vaginal canal and provides a supportive backdrop for the urethral tube. The urethral tube is then permitted to be compressed upon itself between the urinary incontinence device and the symphysis pubis thereby limiting involuntary urine flow.

Disclosed herein is a method of phalloplasty for girth enhancement. It comprises incising minimally the outer skin of a penis; separating the skin and the hypoderm from a part immediately above Buck's fascia and peeling off the skin and the hypoderm in a region ranging from a part proximal to a glans to prepubic junction; forming a mesh structure of multiple slits in a penile implant; and fixing the penile implant to the penis by suture. The formation of a mesh structure of multiple slits or the use of an implant in multiple pieces makes it possible to cope with complications, thereby significantly reducing complications. Also, the multiple slits or multiple pieces form spaces therebetween, which lead to an increase in flexibility between the implant tissues, thereby enjoying the advantages of minimizing discomfort upon erection and reducing the occurrence of penis curvature. The delicate irregularities of the penis may serve as a factor promoting sexual stimulation upon sexual intercourse. Also, upon carvenosal injection therapy for erectile dysfunction, drugs for inducing erections can be easily injected into the space between the multiple slits or multiple pieces.

The invention discloses a stationary fixture for pelvis biomechanics experiment. The fixture is connected to a mechanical testing machine by a base. A first anterior superior iliac spine baffle and a second anterior superior iliac spine baffle of the fixture are respectively connected to a pubic tubercle baffle by a first sacrum stationary jaw and a second sacrum stationary jaw. A top tray of upper margin of pubic bone and a bottom board of lower margin of pubic bone are respectively vertically connected to the pubic tubercle baffle. The first sacrum stationary jaw and the second sacrum stationary jaw are connected to the top tray of upper margin of pubic bone. A sacrum fixing cross slab is fixed on the first sacrum stationary jaw and the second sacrum stationary jaw. A connecting rod is arranged on the lower surface of the top tray of upper margin of pubic bone. A back head of pubic bone is horizontally connected to the connecting rod. The lower head of pubic bone is vertically drilled through the bottom board of lower margin of pubic bone. With the fixture of the invention, the pelvis can be fixed by taking a standing posture to do experiment, and the substance of bone and the structure of pelvic are not destroyed by assembling or detaching the fixture.

The invention discloses an anal levator shaft plane image processing method and a device thereof. The method is characterized by acquiring three-dimensional volume data of a basin floor; according to the three-dimensional volume data, carrying out image detection on a basin-floor-center sagittal image and identifying a pubic symphysis lower margin and a rectum and anal canal connection portion; acquiring a connection line of the pubic symphysis lower margin and the rectum and anal canal connection portion, adjusting the connection line and making the connection line be in a horizontal direction; and according to the connection line of the horizontal direction, adjusting a sampling frame and acquiring an anal levator shaft plane image. By using the anal levator shaft plane image processing method and the device thereof, the pubic symphysis and the rectum and anal canal connection portion can be automatically identified so that the sampling frame is rapidly and accurately adjusted and an anal levator area image is acquired; and accuracy and efficiency of image processing are increased.
