Abstract

An ultrasound device includes a frame and an ultrasound sensor assembly. The frame includes first and second rails spaced-apart relative to one another and a longitudinal section defining a longitudinal axis. The longitudinal section has a distal end portion. The ultrasound sensor assembly configured to enable ultrasound imaging of a field of view and is attached to the distal end portion of the longitudinal section of the frame and oriented such that the field of view is disposed at an oblique angle relative to the longitudinal axis. A surgical system including the ultrasound device and a surgical instrument insertable therethrough is also provided.

First claim

What is claimed is:

1. A surgical system, comprising:
an ultrasound device, including:
a frame defined by first and second rails spaced apart relative to one another, the frame including a longitudinal section defining a longitudinal axis, the longitudinal section having a distal end portion; and
an ultrasound sensor assembly configured to enable ultrasound imaging of a two-dimensional field of view in a viewing direction, the ultrasound sensor assembly being attached to the distal end portion of the longitudinal section of the frame, wherein the ultrasound sensor assembly is disposed in fixed orientation relative to the longitudinal axis with the viewing direction of the two-dimensional field of view disposed at an oblique angle relative to the longitudinal axis and with the longitudinal axis extending coplanarly through the two dimensional field of view, wherein the distal end portion of the longitudinal section of the frame is configured for insertion through a vagina of a patient to position the ultrasound sensor assembly adjacent to or in abutment with a cervix of the patient, wherein the longitudinal section of the frame and the ultrasound sensor assembly cooperate to define a hollow interior extending along the longitudinal axis, the hollow interior closed at a distal end of the hollow interior, closed on opposing sides of the hollow interior by the first and second rails, and open along the top and the bottom of the hollow interior along the longitudinal axis; and

a surgical instrument configured for insertion between the first and second rails at an oblique angle relative to the longitudinal axis such that the surgical instrument extends into the hollow interior through one of the top or the bottom of the hollow interior and out of the hollow interior from another of the top or the bottom of the hollow interior, the surgical instrument configured for insertion, from between the first and second rails through the vagina of the patient, through the cervix of the patient, and into a uterus of the patient, wherein the first and second rails constrain transverse movement of the surgical instrument to maintain the surgical instrument in coplanar relation relative to the two-dimensional field of view of the ultrasound sensor assembly.

2. The surgical system according to claim 1 , wherein the frame of the ultrasound device further includes an upright section disposed at an angle relative to the longitudinal section and a bend interconnecting the upright section and a proximal end portion of the longitudinal section.

3. The surgical system according to claim 2 , wherein the surgical instrument is insertable between the first and second rails of the frame at the bend of the frame or the upright section of the frame in parallel or coaxial orientation relative to the longitudinal axis of the longitudinal section of the frame.

4. The surgical system according to claim 1 , wherein first and second rails constrain transverse movement of the surgical instrument while permitting axial translation, axial rotation, and vertical tilting of the surgical instrument when the surgical instrument is inserted between the first and second rails.

5. The surgical system, according to claim 1 , wherein the ultrasound device further includes at least one spacer disposed between the first and second rails, the at least one spacer securing the first and second rails to one another and maintaining spacing between the first and second rails.

6. The surgical system according to claim 1 , wherein the first and second rails of the frame of the ultrasound device are parallel plates.

7. The surgical system according to claim 1 , further comprising a sterile barrier disposed about the ultrasound sensor assembly and at least a portion of the longitudinal section of the frame.

8. The surgical system according to claim 7 , wherein the surgical instrument, when inserted between the first and second rails, remains external of the sterile barrier.

9. The surgical system according to claim 1 , wherein the ultrasound device further includes a lock disposed between the first and second rails, the lock configured to selectively retain the surgical instrument between the first and second rails in fixed position and orientation relative to the first and second rails.

10. The surgical system according to claim 1 , wherein the surgical device is a hysteroscope configured to receive a working instrument.
