Surgical extractor

A surgical extractor comprising:

• a first hollow tube hereinafter called “slide”, said slide having a rectilinear longitudinal axis and a constant cross-section, a first open end and a second end, and a long radial opening close to the second end, said radial opening extending over more than half of the section of the slide;
• a second hollow tube hereinafter called “pusher”, which is mounted in a sliding manner over the slide;
• several flexible rods hereinafter called “straps”, which extend in line with the pusher and each has a first end fixed in a rigid manner to the pusher and a second end connected in a rigid manner to the slide close to the second end of the same, said straps being distributed to extend over the radial opening of the slide;
• means for applying a pressure onto the pusher so as to:
• in a first step, move the pusher over a given stroke distance from a rest position to an opening position closer to the second end of the slide, such causing the straps to fold up and open like petals over the radial opening and thus to allow grasping in a radial direction of an organ to be extracted from the body of the patient;
• and
• in a second step, bring the pusher back from its opening position to its rest position while forcing, if needs be, the straps to unfold and thus crush the organ grasped by them, such permitting the organ to pass inside the slide and thus to be extracted from the same through the first open end thereof;
• a bit extending over the full length of the slide within the slide for crushing and extracting the grasped organ;
• and
• an external motor to rotate the bit.

• wherein the straps form an integral part of the pusher and have their second ends integral to a ring rigidly connected to the second end of the slide.

A surgical extractor comprising:

• a first hollow tube hereinafter called “slide”, said slide having a rectilinear longitudinal axis and a constant cross-section, a first open end and a second end, and a long radial opening close to the second and, said radial opening extending over more than half of the section of the slide;
• a removable cap for closing the first open end of the slide;
• a second hollow tube hereinafter called “pusher”, which is mounted in a sliding manner over the slide;
• several flexible rods hereinafter called “straps”, which extend in line with the pusher and each has a first end fixed in a rigid manner to the pusher and a second end connected in a rigid manner to the slide close to the second end of the same, said straps being distributed to extend over the radial opening of the slide;
• means for applying a pressure onto the pusher so as to:

• and
• in a second step, bring the pusher back from its opening position to its rest position while forcing, if needs be, the straps to unfold and thus crush the organ grasped by them, such permitting the organ to pass inside the slide and thus to be extracted from the same through the first open end thereof.

A surgical extractor comprising:

• a first hollow tube hereinafter called “slide”, said slide having a rectilinear longitudinal axis and a constant cross-section, a first open end and a second closed end, a radial outlet close to the first open end for connection thereof to a vacuum suction device, and a long radial opening close to the second end, said radial opening extending over more than half of the section of the slide and having a length between 15 and 25 cm, said slide having a length between 40 and 50 cm and a diameter less than 2 cm;
• a second hollow tube hereinafter called “pusher”, which is mounted in a sliding manner over the slide;
• several flexible rods hereinafter called “straps”, which extend in line with the pusher and each has a first end fixed in a rigid manner to the pusher and a second end connected in a rigid manner to the slide close to the second end of the same, said straps being distributed to extend over the radial opening of the slide;
• means for applying a pressure onto the pusher so as to:
• in a first step, move the pusher over a given stroke distance between 4 and 8 cm from a rest position to an opening position closer to the second end of the slide, such causing the straps to fold up and open like petals over the radial opening and thus to allow grasping in a radial direction of an organ to be extracted from the body of the patient;
• and
• in a second step, bring the pusher back from its opening position to its rest position while forcing, if needs be, the straps to unfold and thus crush the organ grasped by them, such permitting the organ to pass inside the slide and thus to be extracted from the same through the first open end thereof.
