 (57) ABSTRACT 

A novel design of a suction device for medical use intended to assist direct (closed technique) entry of the abdomen in medical surgical procedure. The device is applied to the skin of the abdominal wall and after suction is initiated, the deeper layers of the abdominal wall can be grasped by manually lifting on the suction device to provide counter-traction before advancing the needle or trocar into the abdominal cavity. The design improves the proprioceptive sense of laparoscopic trocar penetration of the abdominal wall.

BACKGROUND OF THE INVENTION

  • Field of the Invention

The present invention relates generally to the field of medicine and more specifically it relates to a suction device for performance of abdominal laparoscopic surgical procedures. 

  • Description of the Related Art

Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.

Generally, suction devices are used in Neurosurgery, Cardiac surgery, Gastroenterology, Urology and General Surgery.

The instant invention substantially departs from the conventional designs of the prior art as the suction device has a unique design as it has no moving parts and no ornamentation.

By operation, the device is applied to the skin of the abdominal wall and after suction is initiated, the device becomes firmly attached to the skin and underlying tissue layers. It has a unique circular handle (shown in Fig. 2) which makes it possible to lift up tissue within the device’s suction cup, thus increasing the tension of the underlying soft tissue layers of the abdominal wall. Consequently, the force applied allows penetration the needle or trocar into the abdominal cavity

BRIEF SUMMARY OF THE INVENTION

From the foregoing, it is clear that the types of suction devices in use have many disadvantages inherent in them. The current device, therefore, is unique in that it has a small circular “handle” on the stem of the funnel cup. It is made of stainless steel and takes the shape of a funnel having no ornamentation on the surface and no moving parts. 

This suction device is more effective in providing the counter traction hence improving the proprioceptive sense of laparoscopic trocar penetration of the abdominal wall.
