An instrument for closing, by subcutaneous suturing, an orifice made in the abdominal wall of a patient. The instrument has a piston rod (5) whose end acts on a flexible support strip (8) for needles (7), thus causing them to emerge at an exterior of the lower part (4) of a cannula (3) of the instrument underneath the abdominal wall (2), so that the needle can then penetrate into a thick part of this wall. Also, a method for suturing of orifices after a surgical operation by laparoscopy.

A device and method for elevating skin, subcutaneous tissue, and muscle of a patient during medical procedure, the device comprises at least one opening, a suction port and a ring liner having means for a soft interface between the device and the skin and provides a positive seal between the device and the skin. The opening is located at the top of the device having means for inserting surgical instruments within the patient's body cavity created by separation of the skin, subcutaneous tissue and muscle from the underlying organs. The said method comprises the steps of placing the device on the patient's target medical interventional area for elevating the said area; exerting negative pressure onto the target body area of the patient through the suction port and inserting surgical instruments into patient's abdomen for medical procedure through the opening at the top.

The invention relates to the field of laparoscopic micro-invasive surgery, in particular to a spindly non-pneumoperitoneum device for a single-port laparoscopy. According to the spindly non-pneumoperitoneum device, the defects of small surgery space, poor surgical field exposure and great quantity of abdominal incisions in a traditional non-pneumoperitoneum technology can be overcome. The spindly non-pneumoperitoneum device consists of a fixed frame, a suspension mechanism and a spindle mechanism. Due to the adoption of the technical scheme that a support ring enables spindly spokes to be stretched off and be arrayed in an umbrella shape by upwards lifting a suspender, an anterior abdominal wall is semi-spherically lifted and suspended by the spokes arrayed in an umbrella shape and the phenomenon that the surgery space becomes smaller and narrower due to the fact that abdominal walls on two sides gather towards the middle to extrude intestinal canal to be concentrated to the middle by a suspending pull force of the abdominal walls is avoided; due to adoption of single incision in umbilical region, an illuminating probe, surgical instruments and the like extend into an abdominal cavity for surgery by using a hollow structure of the device; and due to the adoption of a rotational suspension device, the surgical instruments obtain a more favorable operation angle and the problems of small surgery space, insufficient surgical field exposure and great quantity of abdominal incisions in the traditional non-pneumoperitoneum technology are better solved.

Intra-abdominal liver retraction devices and methods of use. One device includes a body, a stabilizing member, and a lifting filament. The stabilizing member is configured to be swiveled so that the device can be introduced through a trocar into the abdomen of a patient. The filament pulls the stabilizing member into engagement with the abdominal wall while a foot section lifts the liver. Another device includes first, second and third sections coupled together by a filament. The first and second sections are pivotably connected by a first pivotable joint. The second and third sections are pivotably connected by a second pivotable joint including the flexible filament. The second and third sections are pivoted with respect to each other to form a support surface to lift the liver by pulling the filament.

A Diastasis Recti Splinting Garment is described which includes a plurality of attached torso straps and pelvic straps which the user wraps around their body and connects to the garment so as to approximate the 2 sides of the abdominal wall, providing support to the linea alba and fascial sheathes to allow for tissue healing. Furthermore, the adjustable angled straps encircle the torso and pelvis of the user to restore the integrity of the core, providing stability to the ribcage, spine and pelvis. Restoring the integrity of the core lends itself to optimal activation of the deep core stabilizers, including the abdominal muscles as well as the musculature of the pelvic floor, back, and diaphragm. This in turn aids in dynamic stability of the spine, ribcage and pelvis. This allows maximum support of the diastasis recti, consequently facilitating tissue healing through balancing intra-abdominal pressure, while still supplying support to the vulnerable pelvic floor and stability to the spine, ribcage and sacroiliac joints.
