This invention relates to medical procedures and apparatus in general, and more particularly to medical procedures and apparatus for manipulating the uterus and/or cervix of a patient.
Various medical examinations and procedures require that the uterus and/or cervix of the patient be manipulated so that the uterus and/or cervix, and the connecting tissues attached to the uterus and/or cervix, can be properly viewed and accessed by the doctor. By way of example but not limitation, such manipulation of the uterus and/or cervix is typically required in a total laparoscopic hysterectomy, a partial laparoscopic hysterectomy, a colpotomy, etc.
To this end, prior art medical instruments have been developed for manipulating the uterus and/or cervix of a patient. These prior art medical instruments are intended to be inserted into the vagina of the patient and have (i) a first portion which contacts the cervix of the patient, and (ii) a second portion which is advanced into the uterus of the patient and is used to manipulate the intermediate and distal portions of the uterus. See
Unfortunately, none of the aforementioned prior art medical instruments adequately and completely perform their function so as to facilitate rapid, easy and atraumatic manipulation of the uterus and/or cervix of a patient so as to provide adequate viewing and access by the doctor.
Thus there is a need for a new and improved method and apparatus for manipulating the uterus and/or cervix of a patient, wherein the new and improved method and apparatus facilitate rapid, easy and atraumatic manipulation of the uterus and/or cervix so as to provide adequate viewing and access by the doctor.
These and other objects are addressed by the present invention, which comprises a new and improved method and apparatus for manipulating the uterus and/or cervix of a patient, wherein the new and improved method and apparatus facilitate rapid, easy and atraumatic manipulation of the uterus and/or cervix so as to provide adequate viewing and access by the doctor.
More particularly, in one form of the invention, there is provided apparatus for manipulating the uterus and/or cervix of a patient, the apparatus comprising:
an elongated shaft having a proximal end and a distal end;
an annular rim connected to the distal end of the elongated shaft; and
In another form of the invention, there is provided apparatus for manipulating the uterus and/or cervix of a patient, the apparatus comprising:
an elongated shaft having a proximal end and a distal end;
an annular rim connected to the distal end of the elongated shaft;
a projection extending distally from the annular rim, the projection being coaxial with the annular rim; and
a guide telescopically mounted to the projection.
In another form of the invention, there is provided apparatus for manipulating the uterus and/or cervix of a patient, the apparatus comprising:
an elongated shaft having a proximal end and a distal end; and
an annular rim connected to the distal end of the elongated shaft;
wherein the rim comprises at least one light.
In another form of the invention, there is provided a method for manipulating the uterus and/or cervix of a patient, the method comprising:
providing apparatus comprising:
advancing the apparatus down the vagina of a patient so that the helical thread of the projection engages the cervix; and
turning the apparatus so that interaction between the helical thread and the cervix advances the apparatus so that the projection is disposed within the uterus and the annular rim engages the vaginal wall at the distal end of the fornix.
In another form of the invention, there is provided a method for manipulating the uterus and/or cervix of a patient, the method comprising:
providing apparatus comprising:
advancing the apparatus down the vagina of a patient so that the projection engages the cervix and enters the uterus; and
telescopically advancing the guide further into the uterus.
In another form of the invention, there is provided a method for manipulating the uterus and/or cervix of a patient, the method comprising:
providing apparatus comprising:
advancing the apparatus down the vagina of a patient; and
using the at least one light to illuminate the anatomy of the patient.

Instrument 5 is intended to be used for manipulating the uterus and/or cervix of a patient. In one preferred method of use, instrument 5 is set so that its cup 15 is aligned with its hollow shaft 20, and guide assembly 115 is set so that it is in its aforementioned retracted position, i.e., so that its atraumatic tip 137 is disposed just distal to the distal end of hollow projection 95. Then instrument 5 is advanced up the vagina of the patient until atraumatic tip 137 of guide 135 and distal tubular portion 105 of hollow projection 95 sit at the entrance to the cervix. Then instrument 5 is gently advanced distally so that atraumatic tip 137 of guide 135 and distal tubular portion 105 of hollow projection 95 enter the cervix and start to enter the interior of the uterus.
This pushing advancement is continued until helical thread 110 on proximal frustoconical portion 100 of hollow projection 95 engages the cervix. Further forward motion is then provided by rotationally turning instrument 5, with helical thread 110 engaging the surrounding walls of the cervix and propelling instrument 5 forward. This forward motion continues, with cup 15 advancing along the fornix and enveloping the cervix, until the distal rim 75 of cup 15 comes to rest against the vaginal wall at the distal end of the fornix. This action secures the distal end of instrument 5 to the cervix, by virtue of the threaded engagement of hollow projection 95 with the surrounding surfaces of the cervix, the envelopment of the cervix by cup 15, and the seating of distal rim 75 of cup 15 on the vaginal wall at the distal end of the fornix.
Seal 183 may then be moved distally along hollow shaft 20 until it seats on the anatomy.
Next, guide assembly 115 is moved distally so that guide 135 extends a substantial distance into the uterus. This is done by squeezing flexible fingers 145 together so as to disengage edges 150 from ratchet teeth 55, pushing flexible fingers distally along hollow shaft 20, and then releasing flexible fingers 145 so that edges 150 re-engage ratchet teeth 55. In one preferred manner of use, guide assembly 115 is moved distally so that the atraumatic distal tip 137 of guide 135 sits just adjacent to the distal end of the uterus, or just short of the distal end of the uterus. This may be achieved by measuring the size of the uterus earlier in the procedure (e.g., using a so-called “uterine sound instrument”, which measures the length of the uterus), and then using the length markings 60 on hollow shaft 20 to appropriately advance flexible fingers 145 along hollow shaft 20 (and hence appropriately advance guide 135 out of hollow projection 95).
Once guide 135 has been advanced an appropriate distance out of hollow projection 95, lever 160 may be used to adjust the orientation of cup 15 relative to hollow shaft 20, whereby to also adjust the orientation of guide 135 relative to hollow shaft 20, whereby to adjust the disposition of the uterus and/or the cervix of the patient. In this respect it will be appreciated that inasmuch as hollow projection 95 threadingly engages the surrounding walls of the cervix, cup 15 encompasses the cervix and the distal rim 75 of cup 15 seats on the vaginal wall at the distal end of the fornix, articulation of cup 15 relative to hollow shaft 20 will cause the disposition of the cervix to be adjusted, and inasmuch as guide 135 extends a substantial distance into the uterus, adjustment of the orientation of guide 135 relative to hollow shaft 20 will cause the disposition of the intermediate and distal portions of the uterus to be adjusted as well.
Significantly, the provision of a light source (e.g., light fibers 175) on distal rim 75 of cup 15 facilitates procedures in several ways. By way of example but not limitation, during the instrument's approach to the cervix, light fibers 175 provide excellent illumination of the vaginal wall, the cervix and the fornix as the instrument is advanced. By way of further example but not limitation, where instrument 5 is to be used for a total laparoscopic hysterectomy, which requires that the uterus be separated from the vaginal wall at the base of the fornix, once the distal rim 75 of cup 15 has settled against the vaginal wall at the distal end of the fornix, the light from light fibers 175 can be seen through the vaginal wall at the base of the fornix (e.g., by an endoscope positioned on the far side of the vaginal wall), thereby providing the doctor with a visual indication of the location of the fornix, and hence a visual cutting guide for severing the vaginal wall at the base of the fornix. In this respect it will be appreciated that inasmuch as light fibers 175 are preferably disposed about substantially the entire perimeter of distal rim 75 of cup 15, the instrument forms a substantially complete ring of light around the cervix at the base of the fornix so as to guide the doctor. In addition, the stepped configuration of distal rim 75 of cup 15 (i.e., the stepped configuration of distal outboard surface 76, annular inner surface 77, and proximal inboard surface 78) can provide the doctor with a tactile cutting guide to facilitate severing the vaginal wall at the distal end of the fornix.
In connection with the foregoing, it should also be appreciated that lever 160 can be used to adjust the disposition of the cervix without advancing guide 135 out of hollow projection 95, or before advancing guide 135 out of hollow projection 95. Thus, in this mode of use, cup 15 and hollow projection 95 alone will provide the engagement used to move the anatomy.
