Abstract

An orifice introducer device for introducing, for example a surgical device, into, for example an orifice of a body, includes a tubular member having a distal end and a proximal end. The distal end is adjustable between a first position for insertion into an orifice and a second position once inserted into the orifice. Alternatively, the orifice introducer device includes a distal portion having a proximal end configured to be detachably secured to the distal end of the tubular member. The distal portion is selectively detachable when the orifice introducer device is positioned in the orifice.

Background technique [0004] There are many surgical procedures that require the introduction of surgical instruments into orifices in the body. An example of this is surgery in which cancerous or abnormal tissue is removed from the gastrointestinal tract by introducing, eg, inserting, a circular suturing device through the patient's mouth or anal cavity. [0005] One of the problems encountered during this type of surgical procedure is that the orifice of the body may be damaged when the surgical instrument is or has been in...
