Description

RECTAL OBTURADOR FOR PROCTOLOGICAL SURGERY

DESCRIPTION

Field of the invention

The present invention relates to a rectal plug for prootological surgery that meets a market need not covered in terms of sterile devices for surgical use to be used during a proctological surgery allowing the surgeon to perform an intervention in better hygienic conditions and thereby improving the treatment provided to the patient. The rectal obturator object of the invention is applicable in medicine, specifically in the field of proctological surgery.

BACKGROUND OF THE INVENTION

Proctologic pathology involves a considerable volume of interventions within a surgical service. To make an estimate is objective, according to the data offered by the Ministry of Health, Consumption and Social Welfare, that in 2015 approximately 21,000 surgical interventions were made proctological. This is 2.27% of the total surgical interventions performed by the General Surgery and Digestive Diseases services of the National Health Service and 10% of the ambulatory major surgical activity.

Among the indications for a proctologic surgery intervention we find the following pathologies and / or diseases:

- hemorrhoidal pathology

- anal fissure

- perianal abscesses

- anal fistula

- anal tumors

- condylomas or anal neoplasia due to HPV

- fecal incontinence

- low rectus tumors

- flaps of anal skin, and

- rectal flaps.

On the other hand, it should be noted that the contamination of the surgical field in proctologic surgery is an undesirable event, since it poses risks during surgery for the patient and for the healthcare professional. In order to avoid such contamination in routine clinical practice, a double approach is carried out with a view to avoiding, during surgery, any interference in the surgical procedure due to contamination with feces or gases:

1) Previous intestinal preparation of the patient who is going to undergo these proctologic interventions and / or,

2) Transitory tamponade during the procedure of proctological surgery with textile material such as for example gauzes.

Prior to the proctological interventions, a bowel preparation of the patients is required, which consists of intestinal cleansing by the use of enemas or anal saline solutions. In many cases these can be administered by the patient at home, but sometimes requires the patient's admission the day before surgery for proper administration. The intestinal preparation is a serious inconvenience for the patient and can produce hydroelectrolyte alterations, local wounds and in any case the result can be below what was expected or even adverse for the performance of the surgery. On the other hand, tampons with textile material during the proctologic procedure are usually ineffective and with the possibility of loss of material in the rectum.

At present, there is no rectal obturator indicated as a single-use surgical device for proctological surgery of the lower rectum and anus indicated for transient tamponade during proctologic surgery. A small obturator anal (with a diameter of 2-3 cm) is known as a container cup. This anal plug is for home use of patients with fecal and / or urinary incontinence, of a size 12-13 mm and not for surgical use in the field of proctologic surgery.

The rectal obturator that we propose is an intrarectal (non-anal) device, for surgical use (hospital and during a surgical procedure) in proctologic procedures (not for home treatment of any pathology) for use by the surgeon (not the patient) .

It is known a shutter for stomata, which prevents leakage or leakage of debris through holes in the abdominal wall to drain the digestive and urinary ducts, through which organic waste substances will leave. The aforementioned device is for home ^use , used by the patient to avoid the emission of content by the stoma that the patient has in his abdomen. This obturator clogs the stoma and is temporarily fixed to the skin by an adhesive disc.

Description of the invention

The subject of the invention is a rectal obturator for proctological surgery comprising a central body with a truncated cone shape and a flange attached to the central body such that the flange comprises a linear body.

The central trunk-shaped body of the rectal obturator for proctologic surgery object of the invention comprises a smaller base and a larger base joined by a generatrix, a perimeter ring in the greater base and at least one through channel passing through the central body communicating the exterior of the side of the minor base with the exterior of the side of the greater base.

In the rectal obturator for proctological surgery object of the invention, the central body is made of a flexible and elastic material. Also the flange is made of a textile material.

In the rectal obturator for proctological surgery object of the invention, each through channel is configured to allow the passage of air and prevent the exit of the feces, preferably being cylindrical in shape, with a diameter between 1 and 3 millimeters, preferably 2 millimeters.

In the rectal obturator for proctological surgery object of the invention, the flange has a length between 12 and 18 centimeters.

In the rectal obturator for proctological surgery object of the invention, the greater base has a diameter between 5 and 11 centimeters, preferably 8 centimeters, and the length of the central body is between 5 and 10 centimeters, preferably 6 centimeters.
