Abstract

A device is described for the diagnosis of internal rectal prolapse, pelvic floor depression and Douglas depth. The invention relates to a device consisting of a flexible, self-expandable, tubular braid (1) with a straight end (2) and a funnel-shaped end (3). The funnel-shaped end (3) has radiologically and endoscopically recognizable color markings (6) at the beginning, in the middle and at the outermost edge. At the straight end (2) are on the left and right side ever a thread (4) and at the funnel-shaped end (3) is a thread (5) attached. The device is introduced transanal in the unexpanded state with the aid of an introducer (7) and released in the rectoanal junction. After the release and self-expansion of the device, with the aid of the funnel-shaped end (3) and the color markings (6) under radiographic fluoroscopy and / or under endoscopic view, the diagnosis of an internal rectal prolapse and pelvic floor depression and Determination of Douglas depth can be made.

Description

Austrian Patent Office AT506 842B1 2010-03-15

Description: [0001] The invention relates to a device for diagnosing an internal rectal prolapse as well as a pelvic floor depression and for determining the Douglas depth. The device consists of a flexible, self-expandable, tubular braid (1) with a straight end (2) and a funnel-shaped end (3). The funnel-shaped end (3) has radiologically and endoscopically recognizable color markings (6) at the beginning, in the middle and at the outermost edge. At the straight end (2) are on the left and right side ever a thread (4) and at the funnel-shaped end (3) is a thread (5) attached.

STATE OF THE ART

W02006 / 046263 describes a diagnostic apparatus consisting of an elongated tubular rod of e.g. vaginal or anal can be introduced. The distal end of the device can be opened, thus keeping a window open to introduce an endoscope and visually examine any pathologies.

US2007 / 0249901A1 describes a radio frequency tagged instrument that can be inserted into the anal canal. A reading device connected to an antenna can perceive a change in the signals due to the change in the position of the rod, whereby the position of the rod can be determined.

US5279548 describes a method which can be used in operations in the peritoneum or in the pelvic cavity of a female patient. After vaginal insertion of a trocar, a membrane can be opened at the distal end to serve as a safety device during surgery.

So far, the following diagnostic methods are performed: [0006] Introduction of a finger of the examiner into the rectoanal transition. However, this procedure is only an approximate assessment, requires appropriate experience of the examiner and is not reproducible or documented.

Defecography (stool emptying x-ray) with contrast of vagina, bladder, small intestine and rectum in video recording. However, this examination is stressful for the patient and expensive for the examiner.

The measurement of the inner rectal prolapse can currently be done only intraoperatively by means of circular Analdilatator.

OBJECT OF THE INVENTION

The object of the invention is a simple to be performed by the examiner, reproducible and documentable examination for the accurate diagnosis of an internal rectal prolapse and a pelvic floor lowering and determining the Douglas depth, without burden on the patient. The device is used for postoperative therapy examination.

SOLUTION OF THE TASKED TASK

The invention solves this problem by the fact that the device is introduced transanal in the unexpandierten state with the aid of an introducer (7), is released at the rectoanal transition under endoscopic view, self-expanding, thereby keeping the anal canal open and thus shows the extent of the distal rectal prolapse. Especially the funnel-shaped end (3) with the color markings (6) allows the diagnosis and measurement of the internal rectal prolapse. The measurement of the rectal prolapse offers the particular advantage that a precise stapler selection can be made before the operation for the treatment of the rectal prolapse.

Furthermore, the device allows due to the funnel-shaped end (3) and the radiologically recognizable color markers (6) a representation of the rectoanal transition in the 1/5 Austrian Patent Office AT506 842B1 2010-03-15

Native X-rays (without contrast medium), the detection of a pelvic floor depression and, with appropriate contrasting of the small intestine, the presentation of an enterocele.

After completion of the examination, the device is removed from the patient again. To remove the device from the rectoanal transition, the thread (5) is pulled to contract the funnel-shaped end (3) and further pulled on the left and right threads (4) of the straight end (2) to completely remove the device , By contracting the funnel-shaped end (3) by means of the thread (5), the diameter of the funnel-shaped end (3) is reduced, which facilitates removal of the device.

EFFECT OF THE INVENTION

Due to the funnel-shaped end (3) with the radiologically recognizable (under radiological fluoroscopy) or endoscopically recognizable color markers (6) of the device, the diagnosis of an internal rectal prolapse and a pelvic floor lowering and determining the Douglas depth allows. The device is introduced transanal in the unexpanded state with the aid of an insertion instrument (7) and released. During the release process, the device expands by itself, which allows keeping open the anal canal and the associated conduct of the investigation.

TITLE AND BRIEF DESCRIPTION OF THE EXISTING DRAWING FIGURES

- flexible, self-expandable, tubular braid - straight end [0016] - funnel-shaped end - each 1 thread at the left and right side of the straight end - thread at the funnel-shaped end [0019 ] - Radiographic and endoscopic color markings at the beginning, in the middle and at the outer edge of the funnel-shaped end

[0020] Introducer FIGURE DESCRIPTION

Fig. 1 shows a device which consists of a flexible, self-expandable, tubular braid 1 with a straight end 2 and a funnel-shaped end 3. The funnel-shaped end 3 has at the beginning, in the middle and at the outermost edge radiographic and endoscopic recognizable color markings 6. At the straight end 2 are each a thread 4 on the left and right side and the funnel-shaped end 3 is a Thread 5 attached. Fig. 2 shows the insertion instrument 7 with which the device is transanal introduced in the unexpanded state.

Fig. 3 shows the released from the introducer 7 and self-expanding device for the diagnosis of an internal rectal prolapse and a pelvic floor lowering and determining the Douglas depth.

By pulling on the thread 5, the funnel-shaped end 3 is contracted to achieve a reduction of the diameter, as shown in Fig. 4, and to facilitate the removal of the device. 2.5
