Definitions
- the present disclosure relates generally to surgical devices and surgical techniques, and more specifically, to surgical device and surgical techniques for performing a hysterectomy on a patient.
- Hysterectomy which is the surgical removal of the uterus, and in some cases the Fallopian tubes and ovaries, is the second most common major operation among women who are of reproductive age in the United States today, second only to cesarean section.
- National Women’s Health Information Center over 600,000 American women have a hysterectomy every year, totaling more than 5 billion dollars in medical expenses.
- Hysterectomy may be performed for a variety of reasons, including removal of reproductive system cancers, prophylactic treatment for those with a strong history of such cancers, treatment for severe and intractable endometriosis and severe fibroids, chronic pelvic pain, and uterine prolapse.
- Hysterectomies may be categorized by the anatomical structures that are removed along with the uterus from the patient.
- One type of hysterectomy is known as a radical hysterectomy, which involves the complete removal of a patient’s uterus, cervix, upper vagina, and parametrium.
- Another hysterectomy procedure is known as a total hysterectomy, which only involves the complete removal of a patient’s uterus and cervix.
- a patient may only require supracervical hysterectomy (also known as a partial hysterectomy), which involves the removal of the uterus but otherwise leaves the cervix in situ.
- Hysterectomies may also be categorized by the surgical approach utilized to remove the uterus and any other associated anatomical structures. Many different surgical approaches are available for performing a hysterectomy, and the degree of intrusiveness and recovery time are dependent on the surgical method chosen. Initially, hysterectomy procedures were only performed via an open incision in a patient’s abdomen, such that the uterus of the patient can be manually accessed (total abdominal hysterectomy (TAH)). About 15% of all hysterectomies in the U.S. are carried out using a TAH procedure, which typically requires a 2-day to 4-day hospital stay, results in a relatively long recovery time (typically 6-8 weeks), and produces large, noticeable, and permanent external scarring. However, a TAH procedure generally requires less surgical skill and time.
- TAH total vaginal hysterectomy
- LAVH laparoscopically assisted vaginal hysterectomy
- a TVH involves making an incision in the vagina and removing the uterus and cervix through the vaginal incision.
- a TVH avoids visible scarring and typically allows for a quicker recovery, as well as less postoperative pain and complications compared to other types of hysterectomies, and is typically the most cost-effective hysterectomy procedure.
- risks associated with a TVH include a slight, but serious risk of shortening or damaging the vagina, which may be caused by the expansion induced to the vaginal area to permit access of the surgeon’s hands to the cervical area through the vagina.
- the choice of the TVH approach is limited, since it is not appropriate if space is required to view abdominal anatomical structures, or if there is a danger of the presence of the cancer cells, or if the uterus is not too enlarged, or if the patient has not delivered vaginally.
- the uterus is accessed through small incisions made in the patient’s belly to provide laparoscopic ports for the laparoscopic equipment (which may be robotically assisted), such as for visualization, surgical procedures, and insufflation.
- laparoscopic equipment which may be robotically assisted
- a uterine manipulator inserted through the vagina, is used to maneuver the uterus and to create space for the laparoscopic equipment and provide access to the desired tissue layers.
- the uterus and cervix may then be laparoscopically severed from the vagina while the uterus, fallopian tubes and ovaries are viewed via a camera attached to a laparoscope.
- the detached uterus and cervix may then be morcellated and removed through one of the laparoscopic ports or removed through the vagina, depending on the size of the uterus.
- the cervix of the patient may be left intact in a supracervical (subtotal) laparoscopic hysterectomy (LSH).
- LSH laparoscopic hysterectomy
- the TLH (or the LSH) approach is considered to be the least invasive, which avoids the open abdominal incision required for TAH procedures and trauma induced to the vaginal area during VH procedures, and generally results in less blood loss, thereby resulting in less patient discomfort, reduced complications, reduced hospital state (on average, one day), and faster return to normal activity (on average, two weeks).
- the TLH also reduces blood loss compared to a TVH, since it allows the blood vessels to be detached from the uterus.
- the TLH approach is especially difficult to perform due to a higher degree of difficulty in securing the uterine arteries and ligaments associated with this approach.
- the posterior side of the uterus is particularly difficult to reach via a TLH, since the visual feedback is poor and special caution is needed to prevent damaging surround structures, such as the bladder or intestines.
- An LAVH is similar to the TLH, except that, rather than laparoscopically, the uterus and cervix are severed from inside of the vagina, with the laparoscopic tools only used for guiding the procedure and visualizing structures, in addition to detaching the uterus from surrounding upper supporting structures (such as the infundibular pelvic and round ligaments. The uterus and cervix are then removed through the vagina.
- TAH total abdominal hysterectomies
- vaginal cuff an opening in the vaginal wall, referred to as a vaginal cuff, is left behind that must be closed via a suturing procedure.
- the less invasive hysterectomy procedures i.e. , the TVH, TLH, or LAVH
- the geometry of this opening can make it difficult to suture effectively, especially when using laparoscopy tools during a TLH or LAVH.
- vaginal cuff dehiscence which is a potentially catastrophic event where the vaginal cuff opens such that the bowel may herniate through the vagina, may occur, thereby requiring immediate surgery.
- the incidence of vaginal cuff dehiscence after a TLH has been found to be approximately 0.5-4%.
- a modifiable risk factor for vaginal cuff dehiscence is surgical technique, which has significant inter-operator variability. For example, once the uterus is severed from the vagina, such that the tissue has been completely separated, the optimal tissue to be sutured must be located. However, it is very difficult to locate and consistently suture this optimal tissue to close the vaginal cuff.

- the vaginal-cervical junction J of the patient P is circumferentially incised distal to the anchor points SP, thereby transecting the uterus U and cervix C from the vagina V of the patient P, and creating a vaginal cuff VCU having the anchor points AP, as illustrated in Fig. 55C (step 328’).
- Steps 330-336 are then performed in the same manner described above with respect to the method 300.
- the vaginal cuff closure kit 240’ (shown in Fig. 52) is assembled into the vaginal cuff closure tool 240, with connection of the proximal ends of the tissue anchors 42b to the vaginal cuff closure tool 240 being part of the assembly process.
- the proximal ends of the distally anchored tissue anchors 42b extending from the vagina V of the patient P are first coupled to the connector device 242 (see Figs. 57A-57B) (step 342).
- Connection between the proximal ends of the distally anchored tissue anchors 42b and the connector device 242 can be made, e.g., using the plug and socket arrangement illustrated in Fig. 41.
- the top set of left, center, and right tissue anchors 42b-1 to 42b-3 that are distally anchored to the top half of the vaginal-cervical junction J1 are respectively affixed to the top row of connectors 250-1 to 250-3 (i.e.
- the tissue anchor 42b-1 distally anchored to the anchor point AP1 at the top left of the vaginal-cervical junction J is connected to the top left connector 250-1 of the connector device 242
- the tissue anchor 42b-2 distally anchored to the anchor point AP2 at the top center of the vaginal-cervical junction J is connected to the top center connector 250-2 of the connector device 242
- the tissue anchor 42b-3 distally anchored to the anchor point AP3 at the top right of the vaginal-cervical junction J is connected to the top right connector 250-3 of the connector device 242)
- the bottom set of left, center, and right tissue anchors 42b-4 to 42b-6 that are distally anchored to the bottom half of the vaginal-cervical junction J2 are respectively affixed to the bottom row of connectors 250-4 to 250-6 (i.e., the tissue anchor 42b-4 distally anchored to the anchor point AP1 at the top bottom of the vaginal-cervical junction J is connected to the
- the proximal ends of the tissue anchors 42b-1 to 42b-6 are uniquely marked to ensure that the tissue anchors 42b-1 to 42b-6 are respectively connected to the corresponding connectors 250-1 to 250-6 of the connector device 242.
- the connector device 242 with the distally anchored tissue anchors 42b, is coupled to the carriage 244, and in particular, affixed within the bore 256 of the carriage 244, such that the tissue anchors 42b extend out from the bore 256 at the proximal end of the shaft 252 (see Figs. 57C-57D) (step 344).
- this can be accomplished by inserting the connector device 242 into the bore 256 at the distal end of the shaft 252, while the pair of open channels 294 of the connector device 242 are properly oriented (clocked) with the pair of ridges 296 in the shaft 252 (see Fig.
- an elongated tool (not shown) can be employed to proximally slide the connector device 242 within the bore 256 of the carriage 244.
- top and bottom distal housing halves 246a, 246b are laterally mated to together over the shaft 252 of the carriage 244 (see Fig. 57E) to fully form vaginal cuff closure tool 240, with the shaft 252 being housed within the distal housing 246, and the distally anchored tissue anchors 42b extending through the distal housing 246 (see Fig. 57F) (step 346).
- this is accomplished by laterally disposing the shaft 252 of the carriage 244 within the bottom half of the enlarged proximal bore portion 264a of the bore 264 of the bottom distal housing half 246b, and laterally disposing the tissue anchors 42b exiting the bore 256 of the carriage 244 within the bottom halves of the tapered bore portion 264a, reduced distal bore portion 264b, and planar cavity 266 and out through the bottom half of the distal aperture 268, of the bottom distal housing half 246b (see Fig.
- the vaginal cuff closure tool 240 having the closed wall 262, bore 264, planar cavity half 266, and distal aperture 268, with the shaft 252 being disposed within the fully formed enlarged proximal bore portion 264a, and the tissue anchors 42b being disposed within the fully formed tapered bore portion 264c, reduced bore portion 264b, and planar cavity 266, and exiting out the fully formed distal aperture 268 (see Fig. 57F).
- the distal housing 246 is distally advanced into the vaginal cavity VC of the patient P until the distal housing 246 is positioned at, and in particular abuts against, the vaginal fornices VF and receives the cervix C of the patient P (e.g., from a proximal position illustrated in Fig. 56B to a distal position illustrated in Fig. 56C) (step 348), and the carriage 244 is proximally translated relative to the distal housing 246, thereby tensioning distally anchored tissue anchors 42b-1 to 42b-6 (which were previously relaxed, as illustrated in Figs. 58A-58B) and collapsing the opposite ends of the vaginal cuff VCU together, as illustrated in Fig. 55D (step 350).
- the distal housing 246 is distally advanced into the vaginal cavity VC of the patient P without translating the carriage 244 and distal housing 246 relative to each other, and once the distal housing 246 abuts against the vaginal fornices VF and receives the cervix C of the patient P, the handle 254 of the carriage 244 is grasped with one hand and pulled in the proximal direction while the distal housing 246 is grasped with the other hand and held in place, thereby proximally translating the carriage 244 relative to the distal housing 246 (i.e.
- the distal housing 246 is distally advanced into the vaginal cavity VC of the patient P by grasping the distal housing 246 with one hand and distally pushing the distal housing 246, while simultaneously proximally translating the carriage 244 relative to the distal housing 246 (i.e., proximally sliding the shaft 252 of the carriage 244 within the bore 256 of the carriage 244) by grasping the handle 254 of the carriage 244 with the other hand and either holding the carriage 244 in place or proximally pulling the carriage 244, thereby taking up the slack in the distally anchored tissue anchors 42b-1 to 42b-6.
- any remaining slack in the distally anchored tissue anchors 42b-1 to 42b-6 may be taken up by continuing to translate the carriage 244 relative to the distal housing 246 (i.e., proximally sliding the shaft 252 of the carriage 244 within the bore 256 of the carriage 244), thereby applying the tension to the proximal ends of the distally anchored tissue anchors 42b-1 to 42b-6 and bringing the opposite ends of the vaginal cuff VCU together to collapse the vaginal cuff VCU.
- the guide features within the vaginal cuff enclosure tool 240 help ensure that the distally anchored tissue anchors 42b-1 to 42b-6 extend between the respective anchor points AP1-AP6 in the vaginal-cervical junction J and the proper locations of the distal aperture 268, as illustrated in Figs. 59A-59B.
- the top and bottom left tissue anchors 42b-1 , 42b-4 and the top and bottom right tissue anchors 42b-3, 42b-6 when tensioned, are spatially constrained in the horizontal plane (the plane of the drawing in Fig. 60).
- the reduced distal bore portion 264b such that the top and bottom left tissue anchors 42b-1 , 42b-4 and the top and bottom right tissue anchors 42b-3, 42b- 6 distally extend at an inward angle toward each other (as projected onto the horizontal plane) from the left connectors 250-1 , 250-4 and the right connectors 250- 3 and 250-6 of the connector device 242, through the bore 256 of the shaft 254 of the carriage 244, and then through the enlarged proximal bore portion 264a and tapered bore portion 264c of the distal housing 246, and then distally extend straight (as projected onto the horizontal plane) through the reduced distal bore portion 264b of the distal housing 246, while the top center tissue anchor 42b-2 and bottom center tissue anchor 42b-4, are not spatially constrained in the horizontal plane, such that the tissue anchors 42b-2, 42b-4 distally extend straight (as projected onto the horizontal plane) from the center connectors 250-2, 250-5 of the connector device 242, through the bore 256 of the shaft
- top and bottom left tissue anchors 42b-1 , 42b-4 and the top and bottom right tissue anchors 42b-3, 42b-6 are then spatially expanded in the horizontal plane from the width w1 of the reduced distal bore portion 264b to the width w2 of the planar cavity 266, such that the top and bottom left tissue anchors 42b-1 , 42b-4 and the top and bottom right tissue anchors 42b-3, 42b-6 distally extend at an outward angle away from each other (as projected onto the horizontal plane) from the reduced distal bore portion 264a of the distal housing 246 through the planar cavity 266 as the tissue anchors 42b-1 , 42b-4 bear against the left bearing surface 272a, and the tissue anchors 42b-3, 42b-6 bear against the right bearing surface 272b, while the top center tissue anchor 42b-2 and bottom center tissue anchor 42b-4 are not spatially expanded in the horizontal plane from the width w1 of the reduced distal bore portion 264b to the width w2 of the planar cavity 266, such that
- top and bottom left tissue anchors 42b-1 , 42b-4 and the top and bottom right tissue anchors 42b-3, 42b- 6 then distally extend (straight or at an outward angle) (as projected onto the horizontal plane) from the distal aperture 268 to the respective anchor points AP1 , AP4 at the top half of the vaginal-cervical junction J1 and the anchor points AP3, AP6 at the bottom half of the vaginal-cervical junction J2, while the top and bottom center tissue anchors 42b-2, 42b-5 distally extend straight (as projected onto the horizontal plane) from the distal aperture 268 to the respective anchor point AP2 at the top half of the vaginal-cervical junction J1 and the anchor point AP5 at the bottom half of the vaginal-cervical junction J2, as illustrated in Figs. 59A-59B.
- top bearing surface 270a and the bottom bearing surface 270b respectively by the top bearing surface 270a and the bottom bearing surface 270b, such that the top set of tissue anchors 42b-1 to 42b-3 and the bottom set of tissue anchors 42b-4 to 42b-6 distally extend at an inward angle toward each other (as projected onto the vertical plane) from the top connectors 250-1 to 250-3 and the bottom connectors 250-4 to 250-6, through the bore 256 of the shaft 254 of the carriage 244, and then through the enlarged proximal bore portion 264a, tapered bore portion 264c, and reduced distal bore portion 264b of the distal housing 246, as the top set of tissue anchors 42b-1 to 42b-3 bear against the top bearing surface 274a, and the bottom set of tissue anchors 42b-4 to 42b-6 bear against the bottom bearing surface 274a.
- top set of tissue anchors 42b-1 to 42b-3 and the bottom set of tissue anchors 42b-4 to 42b-6 are then spatially constrained along vertical plane from the height hi of the reduced distal bore portion 264b to the height h2 of the planar cavity 266, such that the top set of tissue anchors 42b-1 to 42b-3 and the bottom set of tissue anchors 42b-4 to 42b-6 distally extend straight (as projected onto the vertical plane) through the planar cavity 266.
- top set of tissue anchors 42b-1 to 42b-3 and the bottom set of tissue anchors 42b-4 to 42b-6 then distally extend at an outward angle (as projected onto the vertical plane) from the distal aperture 268 to the anchor points AP1-AP3 at the top half of the vaginal-cervical junction J1 and the bottom half of the vaginal-cervical junction J2, as the top set of tissue anchors 42b-1 to 42b-3 and the bottom set of tissue anchors 42b-4 to 42b-6 respectively bear against the top edge 274a and bottom edge 274b of the distal aperture 268, as illustrated in Figs. 59A-59B.
- the top edge 274a and bottom edge 274b of the distal aperture 268 essentially serve to at least partially translate or convert the longitudinal tensile forces applied at the proximal ends of the top set of tissue anchors 42b-1 to 42b-3 and the bottom set of tissue anchors 42b-4 to 42b-6 by the top row of connectors 250-1 to 250-3 of the connector device 242 and the bottom row of connectors 250-4 to 250-6 along the horizontal plane (or frontal plane FP extending between the opposite sides of the vaginal cuff VCU) to lateral tensile forces applied orthogonal to the horizontal plane to the distal ends of the top set of tissue anchors 42b-1 to 42b-3 and the bottom set of tissue anchors 42b-4 to 42b-6 by the anchor points AP1-AP3 at the top half of the vaginal-cervical junction J1 and the by the anchor points AP4- AP6 at the bottom half of the vaginal-cervical junction J2.
- the outward angle (as projected onto the vertical plane) that the top set of tissue anchors 42b-1 to 42b-3 and the bottom set of tissue anchors 42b-4 to 42b-6 extend away from each other is as greater as possible (e.g., greater than 90 degrees) in order to maximize the tensile force used to collapse the vaginal cuff VCU.
- the carriage 244 will be locked to the distal housing 246 simply by releasing the carriage 244 (e.g., by releasing grip of the handle 254 of the carriage 244), such that the tensile forces applied to the distally anchored tissue anchors 42b cause the manually released carriage 244 to slightly be displaced distally relative to the distal housing 246 to cause the cantilevered cogs 278 to fully engage the tooth of the series of teeth 276 of the distal housing 246 that is immediately distal to the cantilevered cogs 278 when the carriage 244 is released.
- one or more sutures 200 are then used to suture the collapsed vaginal cuff VCU in a conventional manner, e.g., laparoscopically, as illustrated in Fig. 55E (step 354).
- the carriage 244 is unlocked from the distal housing 246, such that the carriage 244 may be distally translated relative to the distal housing 246 (step 356).
- Unlocking of the carriage 244 from the distal housing 246 may be accomplished by radially rotating the carriage 244 relative to the distal housing 246 (e.g., by grasping the handle 254 of the carriage 244 and the distal housing 246 and rotating them in opposite directions), thereby disengaging the cantilevered cogs 278 from the series of teeth 276, such that the carriage 244 may be freely translated distally relative to the distal housing 246 as long as the cantilevered cogs 274 are displaced away from the series of teeth 276.
- the carriage 244 is distally translated relative to the distal housing 246, thereby relaxing the distally anchored tissue anchors 42b-1 to 42b-6 (step 358), and the distal housing 246 is proximally retracted from vaginal cavity VC of the patient P, while leaving the distal ends of the tissue anchors 42b-1 to 42b-6 respectively anchored to the anchored points AP1-AP6 of the vaginal-cervical junction J of the patient P (e.g., from a distal position illustrated in Fig. 56C to a proximal position illustrated in Fig. 56B) (step 360).
- the portion of the distal housing 246 extending from the vaginal cavity VC of the patient P is grasped with one hand and held in place, while the handle 254 of the carriage 244 is grasped with the other hand and pulled in the distal direction, thereby distally translating the carriage 244 relative to the distal housing 246 (i.e., distally sliding the shaft 252 of the carriage 244 within the bore 256 of the carriage 244), thereby relaxing the proximal ends of the distally anchored tissue anchors 42b-1 to 42b-6, and then the distal housing 246 is proximally retracted from the vaginal cavity VC of the patient P while leaving the distal ends of the slackened tissue anchors 42b-1 to 42b-6 respectively anchored to the anchored points AP1-AP6 of the vaginal-cervical junction J of the patient P.
- the carriage 244 is distally translated relative to the distal housing 246 (i.e., distally sliding the shaft 252 of the carriage 244 within the bore 256 of the carriage 244) by grasping the handle 254 of the carriage 244 with one hand and distally pushing the carriage 244, thereby slackening the distally anchored tissue anchors 42b, while simultaneously proximally retracting the distal housing 246 from the vaginal cavity VC of the patient P by grasping the portion of the distal housing 246 extending from the vaginal cavity VC of the patient P with the other hand and proximally pulling the distal housing 246 while leaving the distal ends of the slackened tissue anchors 42b-1 to 42b-6 respectively anchored to the anchored points AP1-AP6 of the vaginal-cervical junction J of the patient P.
- vaginal cuff closure 240 is disassembled, with disconnection of the proximal ends of the tissue anchors 42b from the vaginal cuff closure tool 240 being part of the disassembly process.
- top and bottom distal housing halves 246a, 246b of the full formed vaginal cuff closure tool 240 are laterally de-mated from each other (see Fig. 57E), and the shaft 252 of the carriage 244, along with the distally anchored tissue anchors 42b removed (see Fig. 57D) (step 362).
- the connector device 242 with the distally anchored tissue anchors 42b is decoupled from the carriage 244, and in particular, removed from the bore 256 of the carriage 244 (see Figs. 57C-57D) (step 364).
- this can be accomplished by inserting a pair of tools (not shown) into the pair of access ports 297 on the handle 254 of the carriage 244 to push the pair of cantilevered detents 288 of the connector device 242 radially inward, thus disengaging the pair of cantilevered detents 288 from the pair of apertures 290 formed through the wall of the shaft 252 (see Figs. 42 and 53), and proximally sliding the connector device 242 within the bore 256 and out of the proximal end of the shaft 252. Then, the proximal ends of the distally anchored tissue anchors 42b are decoupled from the connector device 242 (see Figs. 57A-57B) (step 366).
- tissue anchors 42b are removed from the vaginal-cervical junction J of the patient (step 368). This can be accomplished, e.g., laparoscopically by grasping the tissue retention assemblies (e.g., the barbs 222 in the case that the tissue anchors 42b’ illustrated in Fig. 33 are used, or the cross-bars 226 in the case that the tissue anchors 42b” illustrated in Fig. 35 are used) of the tissue anchors 42b with pliers and pulling them into the abdominal cavity AC, and then out of the laparoscopic ports.
- tissue retention assemblies e.g., the barbs 222 in the case that the tissue anchors 42b’ illustrated in Fig. 33 are used, or the cross-bars 226 in the case that the tissue anchors 42b” illustrated in Fig. 35 are used
