Tissue removal and manipulator device for LAVH and related surgeries
View Patent ↗The invention is incorporated into a tissue removal and manipulation device for vaginal hysterectomies and related surgeries. The present invention solves the suturing problem of the prior art devices by providing a device that not only can manipulate the uterus during surgery but remove the uterus without the need for suturing.
1. A device for the manipulation of the uterus comprising:
an elongated shaft having a distal end, a proximal end and an outer surface;
a plurality of barbs located on the elongated shaft, the barbs having at least two positions: a first position where the barbs are below the outer surface of the elongated shaft, and a second position where the barbs project beyond the outer surface of the shaft;
a cervical cup slidably connected to the elongated shaft via a hole in a bottom of the cervical cup; an open end of the cervical cup being oriented on the elongated shaft to oppose the barbs when the barbs are in the second position; and
an expandable balloon connected to the distal end of the elongated shaft,
wherein during use of the device, the cervical cup is placed on the outside of the cervix, opposing the barbs when the barbs are in the second position to engage the uterus and remove the uterus when the device is removed; and
the cervical cup is illuminated via LED light.
2. The device according to claim 1 wherein the illumination occurs along a rim of the top portion of the cup.
3. The device according to claim 1 , further comprising an anti-backslide collar slidably connected to the elongated shaft.
4. The device according to claim 1 , wherein the expandable balloon comprises knobs on the outside surface.
5. The device according to claim 4 , wherein the knobs are in the shape of paddle scoops.
6. The device according to claim 1 , the barbs each comprising two segments, a tissue-hooking segment and a shaft sliding segment, wherein the tissue-hooking segment and the shaft sliding segment are separated by an acute angle when in the second position.
7. A device for the manipulation of the uterus comprising:
an elongated shaft having a distal end, a proximal end and an outer surface;
a plurality of barbs located on the elongated shaft, the barbs having at least two positions: a first position where the barbs are below the outer surface of the elongated shaft, and a second position where the barbs project beyond the outer surface of the shaft after the barbs are moved along a longitudinal direction of the shaft from the first position;
a cervical cup slidably connected to the elongated shaft via a hole in a bottom of the cervical cup; an open end of the cervical cup being oriented on the elongated shaft to oppose the barbs when the barbs are in the second position; and
an expandable balloon connected to the distal end of the elongated shaft,
wherein during use of the device, the cervical cup is placed on the outside of the cervix, opposing the barbs when the barbs are in the second position to engage the uterus and remove the uterus when the device is removed; and
the cervical cup is illuminated via LED light.
8. The device according to claim 7 wherein the illumination occurs along a rim of the top portion of the cup.
9. The device according to claim 7 , further comprising an anti-backslide collar slidably connected to the elongated shaft.
10. The device according to claim 7 , wherein the expandable balloon comprises knobs on the outside surface.
11. The device according to claim 10 , wherein the knobs are in the shape of paddle scoops.
12. The device according to claim 7 , the barbs each comprising two segments, a tissue-hooking segment and a shaft sliding segment, wherein the tissue-hooking segment and the shaft sliding segment are separated by an acute angle when in the second position.
13. A device for the manipulation of the uterus comprising:
an elongated shaft having a distal end, a proximal end and an outer surface;
a plurality of barbs located on the elongated shaft, the barbs having at least two positions: a first position where the barbs are below the outer surface of the elongated shaft, and a second position where the barbs project beyond the outer surface of the shaft after the barbs rotate relative to the shaft about an axis perpendicular to a longitudinal direction of the shaft from the first position;
a cervical cup slidably connected to the elongated shaft via a hole in a bottom of the cervical cup; an open end of the cervical cup being oriented on the elongated shaft to oppose the barbs when the barbs are in the second position; and
an expandable balloon connected to the distal end of the elongated shaft,
wherein during use of the device, the cervical cup is placed on the outside of the cervix, opposing the barbs when the barbs are in the second position to engage the uterus and remove the uterus when the device is removed; and
the cervical cup is illuminated via LED light.
14. The device according to claim 13 , further comprising an anti-backslide collar slidably connected to the elongated shaft.
