Definitions
- the invention relates to a device for pressure measurements between adjacent tissue layers in the human body.
- the lateral vaginal vault is sutured by suturing the upper edge of the upper pubic branch, the sutures being pulled through the so-called Cooperic ligament at the top.
- This seam is not drawn completely, but rather a loop is drawn that sews on the cooperic ligament and the lateral vaginal vault without leading to direct contact between the two structures.
- the thread tension was defined according to the feeling and experience of the operating surgeon.
- an overcorrection occurs, which necessitates intermittent bladder catheterization, sometimes even a permanent catheter.
- significantly higher hospital costs occur, after which the patients are discharged into primary care with appropriate follow-up care, which also entails high follow-up costs.
- Another disadvantage of this method is seen in the fact that in many patients there are recurrent operations of the overcorrections, which in turn drive up the costs considerably.
- the device for pressure measurements between adjacent tissue layers in the human body consists of at least one elastic film and a tube, the elastic film being connected at its edge regions to form a gas- and liquid-tight element, in the lumen of which there is at least one Tube is that the surface of the element is changeable, this change being detectable via a medium located in the element 25 and in the hose and that the element is positioned between the anterior vaginal wall with the urethra thereon and the symphysic rear side.
- a correct thread tension can be achieved at any time, which is independent of the experience and the feeling of the surgeon.
- the tissue layers of the anterior vaginal wall with the urethra lying thereon and the symphysic rear side come closer, which leads to a corresponding pressure on the device according to the invention, which can be detected and controlled by measuring elements located at the end of the tube.
- there is a tube in the edge region of the element which is connected to the element in a gas-tight and liquid-tight manner and through which an element can be optimally transmitted and therefore faster and, above all, more accurate measurements of the pressure.
- both the element and the hose consist of a polymeric material, which can thus be made available economically, in sufficient quantities and in reproducible quality.
- a transparent polymeric material is used for the element and the tube, which allows visual control at any time as to whether the filled lumens and volumes are filled in such a way that there are no air bubbles in the system which lead to a Impairment of the transmission frequency.
- the invention teaches that the tube connected to the element is set to have X-ray contrast, which in turn means that the position of the element can be set very precisely by the operator and can be controlled at any time.
- the recurrence rate can be significantly reduced from currently 30 to 40% through intraoperative registration, which in addition to the cost reduction leads to a significantly higher patient satisfaction.
- FIG. 1 Device according to the invention
- Figure 2 Use of the device according to the invention in the human body
- FIG. 1 shows the device 1 according to the invention for pressure measurements.
- this consists of an elastic film 2, which is sealed gas and liquid-tight at its edge regions 21, 22, 23 and 24.
- the volume 26 of the resulting element 25 is the free end 31 of the hose
- the free end 41 of a hose is spaced from the free end 31 of the hose 3
- hose 4 positioned in the volume 26 of the element 25, the hose 4 being connected to the element 25 in a gas-tight and liquid-tight manner.
- connecting elements 5, 6 are attached in one piece, to which the required measuring elements 7, 8 can be connected.
- FIG. 2 shows the device 1 according to the invention when used in the human body.
- the element 25 of the device 1 according to the invention is positioned between the pubic bone 100 and the bladder 101.
- the bladder 101 is supported on the uterus 102, on the upper divider arch 103 and on the pubic bone 100.
- the surgeon exerts pressure on the element 25 by tightening the threads 104 via the bladder 101.
- the resulting pressure difference is forwarded via the hose 3 to the associated measuring element 7, which is positioned outside the human body within sight of the surgeon, and is registered by the surgeon.
- the pressure on the element 25 of the device 1 according to the invention changes, so that the surgeon when a minimum or Limit value, which is displayed on the measuring element 7, can knot the threads 104. After the device 1 according to the invention has been removed from the human body, the operation can be concluded positively.
