Access device having modular inserts and supporting accessories used in minimally invasive surgical procedures
A percutaneous access device for use in minimally invasive surgery includes an elongated body having a proximal portion and an opposing distal portion. The proximal portion has a proximal bore extending therethrough and the distal portion has a distal bore extending therethrough. The distal portion of the body is hingedly connected to the proximal portion in a first percutaneous access position and a second anchoring position. In the first percutaneous access position the distal and proximal bores are linearly aligned when a surgical instrument is inserted into both the proximal and distal bores. In the second anchoring position the distal bore is angularly displaced from the proximal bore when the surgical instrument is removed from the distal bore.
1. A percutaneous access device for use in minimally invasive surgery, comprising:
an elongated body having a proximal portion and an opposing distal portion, the proximal portion having a proximal bore extending therethrough and the distal portion having a distal bore extending therethrough, wherein the distal portion of the elongated body is hingedly connected to the proximal portion in a first percutaneous access position in which the distal and proximal bores are linearly aligned along an axis of the elongated body when at least one surgical instrument is inserted into both the proximal and distal bores and a second anchoring position in which the entire distal bore is angularly displaced to a side from the proximal bore when the at least one surgical instrument is removed from the distal portion, wherein the proximal portion of the elongated body includes an O-ring seal configured to slideably engage with an outer surface of the elongated body.
2. The access device of claim 1 , wherein the distal portion of the elongated body includes shape memory material configured to automatically hinge the distal portion from the first position to the second position when the at least one surgical instrument is slidably removed from the distal bore.
3. The access device of claim 1 , wherein when the distal portion is in the second position, the proximal bore includes an open end configured to allow the at least one surgical instrument access to the interior of the patient's body.
4. The access device of claim 1 , wherein when the distal portion in the first position the distal bore is sealed by a distal tip.
5. The access device of claim 1 , wherein when the distal portion is in the second position, the distal portion is oriented at an angle of approximately ninety degrees with respect to the elongated body.
6. The access device of claim 1 , further comprising an instrument channel extending along a perimeter of the elongated body from a proximal end thereof to a distal end thereof, which is configured to accept a guidewire therethrough.
7. The access device of claim 1 , wherein the O-ring seal is configured to provide a barrier to advancement of the device through the patient's body when the seal reaches the skin surface.
8. The access device of claim 1 , wherein the O-ring seal includes a sensor configured to measure the longitudinal advancement of the device within the patient's body.
9. The access device of claim 1 , wherein the distal portion is adapted and configured to support one or more accessories used during a surgical procedure.
10. The access device of claim 9 , wherein the accessories associated with the distal portion are selected from the group consisting of an optical imaging device, a camera device, a scope, a video device, a light source, a lighting device, a laser device, a measuring device, a laser measuring device, a signal transmitting device, a signal receiving device, a signal processing device, a memory storage device, a wiring device, a servo driven device, a gear device, an irrigation device, and/or a suction device.
11. The access device of claim 9 , further comprising a power source electronically coupled to a cable extending along the elongated body to the distal portion configured to provide power to the one or more accessories.
12. A percutaneous access device for use in minimally invasive surgery, comprising:
an elongated body having a proximal portion and an opposing distal portion, the proximal portion having a proximal bore extending therethrough and the distal portion having a distal bore extending therethrough, wherein the distal portion of the elongated body is hingedly connected to the proximal portion in a first percutaneous access position in which the distal and proximal bores are linearly aligned along an axis of the elongated body when at least one surgical instrument is inserted into both the proximal and distal bores and a second anchoring position in which the entire distal bore is angularly displaced to a side from the proximal bore when at least one surgical instrument is removed from the distal bore, and
wherein when the distal portion is in the first position the distal bore is sealed by a distal tip and wherein when the distal portion is in the second position the proximal bore includes an open end allowing the at least one surgical instrument access to the interior of the patient's body, and wherein the proximal portion of the elongated body includes an O-ring seal configured to be slideably engaged with an outer surface of the elongated body.
13. The access device of claim 12 , wherein the distal portion of the elongated body includes shape memory material configured to automatically hinge the distal portion from the first position to the second position when the at least one surgical instrument is slidably removed from the distal bore.
14. The access device of claim 12 , wherein the distal portion is adapted and configured to support one or more accessories used during a surgical procedure.
15. The access device of claim 12 , further comprising an instrument channel along a perimeter of the elongated body from the proximal portion to the distal portion configured to accept a guidewire therethrough.
