Laparoscope system
A visual system for laparoscopy comprising a visual device having a visual head member and an elongated connector; a manipulation device having a handheld operation portion, an insertion portion and a first contact element; and an external device comprising means to communicate with the vision head member, via the first contact element, when the elongated connector is mounted in an lumen of the insertion portion. The insertion portion of the manipulation device is configured to be extendable out from a body cavity through an airtight passage whereby the elongated connector is configured to be slidably mounted into the lumen of the insertion portion outside of the body cavity upon the insertion portion is withdrawn into the body cavity.
1. A method of assembling a visual system, the method comprising:
extending a distal end of an insertion portion of a manipulation device out of a body cavity from inside the body cavity through a passage;
electrically connecting a visual device to a handheld operation portion of the manipulation device by inserting an elongated connector of the visual device into a distal opening of a lumen of the insertion portion; and
withdrawing the visual device into the body cavity through the passage.
2. The method of claim 1 , wherein connecting the visual device to the manipulation device includes connecting the elongated connector to a contact element inside of the manipulation device.
3. The method of claim 2 , wherein connecting the visual device to the manipulation device includes connecting the elongated connector to a contact element inside of a handheld operation portion of the manipulation device.
4. The method of claim 1 , wherein the insertion portion includes a sharp or chamfered distal tip.
5. The method of claim 1 , wherein the visual device comprises at least one of a lens, a visual signal conductor, a digital signal conductor, a printed circuit board (PCB), an image sensor, and an illumination source.
6. The method of claim 1 , wherein the visual device comprises a housing, at least one optical element, a light-emitting diode (LED), and an image sensor circuit.
7. The method of claim 1 , further comprising using the visual device to collect, to reflect and/or to project light to and/or from a target.
8. The method of claim 1 , wherein the insertion portion has a maximal outer diameter of at most 3 mm, and a vision head member of the visual device has a diameter of at least 5 mm.
9. The method of claim 1 , further comprising: passing a sleeve into the body cavity through the passage until an end of the sleeve is adjacent to a distal end of the insertion portion; and passing the insertion portion into the sleeve.
10. The method of claim 9 , wherein the sleeve is passed into the body cavity telescopically through a laparoscopic port in the passage.
