Method for positioning a catheter guide element in a patient and kit for use in said method

A method for positioning a guide element in a patient and a kit for use in the method. In one embodiment, the method involves transorally inserting an endoscope into a patient's stomach. An incision site is externally indicated by transilluminating the stomach and abdominal walls of the patient from within the stomach. Next, a scalpel incision is made at the indicated incision site, and an access needle is inserted into the incision, the proximal end of the access needle remaining external to the patient and the distal end of the access needle extending into the patient's stomach. The stylet of the access needle is then removed from the patient while keeping the cannula in place. Next, the distal end of a grasping tool is inserted through the cannula and into the patient's stomach. The looped leading end of a pullwire is then inserted through the endoscope and into the stomach. The tool is then manipulated until a distal hook on the tool catches the looped leading end. Next, the tool and the looped leading end are withdrawn from the patient through the cannula. The endoscope is then withdrawn from the patient over the trailing end of the pullwire. In this manner, the pullwire is positioned so that the trailing end of the pullwire extends from the patient's mouth and the leading end of the pullwire extends from the incision.

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.

Diastasis Recti Splinting Garment

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.
