Description

Laparoscopic access device
INVENTION FIELD
This invention is related to a hydatidiform mole improvement. More specifically, it covers a video laparoscopy hydatidiform mole of one and only access, equipped with an inflatable chamber that permits the fixation of the hydatidiform mole on the abdominal wall, permitting the condition of a fixed portal for introduction of claws, and providing sealing of the pneumo-peritoneum in an efficient form. INVENTION ANTECEDENTS The video laparoscopy surgery is carried out with the help of adequate instruments and devices in order to obtain a visualization of the abdominal cavity without the need of large incisions and, consequently, with less surgical trauma. This type of intervention needs, then, that the abdominal cavity is transformed from virtual into actual by means of gas insufflation.
In the case of intra-abdominal procedures, the use of instruments is indispensable. It is therefore necessary that the claws gain access to the peritoneal cavity, without the gas escaping with the loss of the operating field. Hydatidiform moles are the instruments that permit to carry out these procedures. Regularly, two or more hydatidiform moles are simultaneously used for carrying out the video laparoscopic procedures, with diameters varying between 3 and 13 mm. Several incisions are therefore necessary on the patient, what constitutes a new surgical intervention that includes cuts on tissues, vessels and muscles, with potential infection focus and hernias formation.
So, it is necessary to count on a hydatidiform mole that permits a condition of a fixed portal for claws introduction and the sealing of the pneumo-peritoneum in an efficient form. That improvement in the hydatid iform mole is described and vindicated in this request. SUMMARY
In general terms, this invention has to do with an improvement of the hydatidiform mole that includes a cylindrical format body featured in the internal region with a rigid structure presenting at the distal extremity an inflatable chamber, with a central region featured with passing orifices aligned with the passing orifices located on the base, at the proximal extremity a base featured with passing orifices aligned with the passing orifices at the distal extremity, and a surface featured with a carbonic gas insufflation valve connecting to the internal region of the cylindrical body, and a retention valve featured with a link connected to the inflatable chamber by means of a flexible tube.
It is a characteristic of the invention an improvement of the hydatidiform mole featured with an inflatable chamber, which promotes the fixation of the hydatidiform mole on the abdominal wall of the patient, providing for a portal for claws arrangement and pneumo- peritoneum sealing.
It is a characteristic of the invention a hydatidiform mole improvement that provides for the introduction into the abdominal cavity of the patient through an incision at the umbilical region, with a chamber insufflation of the mentioned hydatidiform mole at a later time.
It is a characteristic of the invention a hydatidiform mole improvement that presents less complexity with the provision for a single body part that promotes the claws arrangement and the pneumo-peritoneum sealing during the procedure, permitting handling by the surgeon. BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 presents a view under a perspective.
Figure 2 presents a front view.
Figure 2 presents a view of the AA section. Figure 3 presents a representation of the claws arranged on the hydatidiform mole body. DETAILED DESCRIPTION OF THE INVENTION
The hydatidiform mole improvement, object of this invention, consists in cylindrical shape body (100) that presents an inflatable chamber at the distal extremity (10) and a base at the proximal extremity (20), featured of passing orifices (21 ) which permit the claws introduction and sealing (200).
The inflatable chamber (10) presents a central region featured with passing orifices (11 ) aligned to the passing orifices (21 ) arranged on the base (20). Those orifices (11 ) promote the exit of the active part of the claws (200).
The base (20) is featured with passing orifices (21 ) aligned to the passing orifices (11 ) arranged at the distal extremity. That base (20) presents the projection of a skirt (22) with diameter widening relatively to the cylindrical body (100). That skirt (22) is adequate for support on the external wall of the patient's abdomen.
The cylindrical body (100) presents a malleable surface, preferably made of silicon. That cylindrical body (100) is featured in the internal region with a rigid structure (30) preferably made of plastic material, which promotes the structuring of that cylindrical body (100).
On the surface of the cylindrical body (100) a carbonic gas insufflation valve is arranged (40), which connects to the internal region of the cylindrical body (100) promoting the insufflation of the abdominal cavity with the objective of maintaining the pneumoperitoneum.
On the surface of the cylindrical body (100) a retention valve is arranged (50), connected to the inflatable chamber (10) by means of a flexible tube (51 ). That retention valve (50) has the objective of inflating the chamber (10) and, so, maintaining the hydatidiform mole fixed to the abdominal wall.
The retention valve (50) presents a connection (52) to provide for air input for insufflation of the inflatable chamber (10). The cylindrical body (100), when it is deflated, is introduced into the abdominal cavity through an incision at the umbilical region. After it is introduced, the chamber (10) is inflated through the retention valve (50), promoting the cylindrical body fixation (10) on the patient's abdominal wall. So, the cylindrical body (10) permits the claws introduction (200) through the passing orifices (21 ) and the sealing of the pneumo-peritoneum.
For removing the cylindrical body (100) from the abdominal cavity, the chamber (20) is deflated by means of intervention on the retention valve (50).
