Devices and systems for providing sensors in parallel with medical tools
Disclosed are systems, devices, and methods for using sensor sleeves with surgical tools. In an aspect of the present disclosure, a sensor sleeve includes a tubular body defining a central longitudinal axis and having a lumen defined therethrough, the tubular body being configured to receive a tool, a plurality sensors attached to the tubular body, a cabling extending distally from the tubular body, and an interface connector coupled to the cabling and configured to interface with a navigation system.
1. A sensor sleeve for use with a tool, the sensor sleeve comprising:
a tubular body having a proximal end and a distal end, defining a central longitudinal axis, and having a lumen defined therethrough, the tubular body being configured to receive the tool through the lumen;
a plurality of sensors attached to the tubular body;
a cabling extending proximally from the proximal end of the tubular body, the cabling comprising an outer surface and a plurality of o-rings,
wherein the o-rings are configured to be coupled to the outer surface of the cabling and to secure the cabling to an outside surface of the tool, wherein the outside surface of the tool and the outside surface of the cabling are against an inner surface of the plurality of o-rings when the tool is disposed through the plurality of o-rings; and
an interface connector coupled to the cabling and configured to interface with a navigation system.
2. The sensor sleeve according to claim 1 , wherein the lumen has an inner surface fabricated at least partially from a lubricious material.
3. The sensor sleeve according to claim 1 , wherein the tubular body is fabricated at least partially from a flexible biocompatible material.
4. The sensor sleeve according to claim 1 , wherein the tubular body is cylindrical.
5. The sensor sleeve according to claim 1 , wherein the plurality of sensors is selected from the group consisting of electromagnetic (EM) sensors, ultrasound sensors, optical sensors, and piezoelectric polyvinylidenefluoride (PVDF) film.
6. The sensor sleeve according to claim 1 , wherein the tubular body further includes a first shell and a second shell hingedly connected together along a first axis that extends in a direction parallel to the central longitudinal axis.
7. The sensor sleeve according to claim 6 , further including:
a plurality of snaps attached to the first shell; and
a plurality of recesses attached to the second shell.
8. The sensor sleeve according to claim 7 , wherein the first shell and second shell are capable of hingedly opening along the first axis.
9. The sensor sleeve according to claim 7 , wherein the tubular body is configured to transition from a first position to a second position.
10. The sensor sleeve according to claim 9 , wherein the first position is open and the second position is closed.
11. The sensor sleeve according to claim 10 , wherein, while in the first position, the first shell and the second shell are semi-cylindrical.
12. The sensor sleeve according to claim 10 , wherein, while in the second position, the first shell and the second shell are connected along a second axis that extends in a direction parallel to the central longitudinal axis and the first axis.
13. The sensor sleeve according to claim 10 , wherein, while in the second position, the plurality of snaps and the plurality of recesses are mateably engaged.
14. The sensor sleeve according to claim 6 , wherein the tubular body is fabricated at least partially from a semi-rigid biocompatible material.
15. The sensor sleeve according to claim 1 , wherein the tubular body includes an opening slit along an axis that extends in a direction parallel to the central longitudinal axis.
16. The sensor sleeve according to claim 15 , wherein the tubular body is configured to transition from an open position to a closed position along the opening slit and is self-biased in the closed position.
