METHODS FOR TRANSCERVICAL STERILIZATION

Abstract

A method of sterilizing a female patient includes cutting into a fundus of a uterus of the female patient to form a flap. The method also includes securing the flap to a wall of the uterus to occlude a fallopian tube of the female patient.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the disclosure and, together with a general description of the disclosure given above, and the detailed description of the embodiment(s) given below, serve to explain the principles of the disclosure, wherein:

[0012] FIG. 1 is a front view illustrating female reproductive anatomy with a surgical instrument inserted into a patient's uterus in accordance with the principles of this disclosure; and

[0013] FIGS. 2 and 3 are progressive views illustrating a method for transcervical sterilization of the female reproductive anatomy with the surgical instrument of FIG. 1.

DETAILED DESCRIPTION

[0014] Aspects of this disclosure are described in detail with reference to the drawings, in which like reference numerals designate identical or corresponding elements in each of the several views. As commonly known, the term clinician refers to a doctor (e.g., a surgeon), a nurse, or any other care provider and may include support personnel. In the following description, well-known functions or constructions are not described in detail to avoid obscuring this disclosure in unnecessary detail.

[0015] In general, this disclosure describes a method for occluding fallopian tubes to effectuate immediate sterilization without abdominal incisions.

[0016] As seen in FIGS. 1-3, the female reproductive organs include the vagina V, the uterus U, the fallopian tubes FT, and the ovaries 0. There are two fallopian tubes FT attached to a side of the uterus U that open into the uterus U at tubal ostia TO. Each fallopian tube FT defines a passageway P that leads to one of the ovaries 0. The uterus U includes the fundus F or the broad curved upper area to which the fallopian tubes FT attach. The uterus U also includes the body B or the main part of the uterus U which starts directly below the fallopian tubes FT and continues downward until walls W of the body B and the uterine cavity C defined by the walls W of the body B begin to narrow. The isthmus I of the uterus U is the lower, narrow neck region of the uterus U that extends to the cervix CX, which opens into the vagina V. Lining the uterine cavity C is a mucous membrane known as the endometrium E under which the myometrium M or the smooth muscle tissue of the uterus U, is disposed.

[0017] To sterilize a female patient, a clinician can insert (e.g., transvaginally) a surgical instrument 10, for example, an electrosurgical instrument with a cutter 12 such as a loop electrode for transecting and/or resecting tissue, into the uterus U (e.g., transcervically). For a more detailed description of one example of such an electrosurgical instrument, reference can be made to U.S. Patent Application Publication No. 2016/0089199 by Sartor et al., the entire contents of which are incorporated by reference herein. Although shown and described herein as an electrosurgical instrument, surgical instrument 10 can be any suitable surgical instrument configured to transect and/or resect tissue (e.g., scalpel).

[0018] Cutter 12 of surgical instrument 10 is then positioned in the uterine cavity C next to a first side of the fundus F adjacent to the tubal ostia TO of first one of the fallopian tubes FT where a cut line CL is identified in the fundus F. The clinician then cuts partially into the fundus F along the cut line CL with cutter 12 of surgical instrument 10 to define a flap X by the cut line CL that is configured to totally occlude tubal ostia TO of the adjacent fallopian tube FT. The clinician may then move the cutter 12 to a second side of the fundus F adjacent to the tubal ostia TO of the other fallopian tube FT (e.g., a second one) to form another flap X in the same manner with respect to the tubal ostia TO of this second fallopian tube FT.

[0019] Each cut line CL is positioned to enable the respective flaps X to depend from the fundus F (FIG. 3) and occlude the respective tubal ostia TO upon completion of the respective cuts. With the flaps X blocking off access into the passageway P of the respective fallopian tubes FT, free ends of the flaps X can be secured to the body B of the uterus U. For example, a fastener applier 20, such as a tack applier, can be inserted into the uterine cavity C to fire a fastener 22 (e.g., a tack) into each flap X to secure each flap X to the body B of the uterus U. As can be appreciated, any suitable fastener applier or stitching device (e.g., suture) can be utilized to secure flap X to the body B of the uterus U. For a more detailed description of such devices, reference can be made, for example, to U.S. Pat. No. 10,085,746 to Fischvogt et al., U.S. Pat. No. 9,358,010 to Wenchell et al., and/or U.S. Pat. No. 8,337,515 to Sniffin et al., the entire contents of each of which are incorporated by reference herein.

[0020] In some aspects of this disclosure, the flap X on the first side can be secured to the body B of the uterus U before the other flap X is formed.

[0021] Advantageously, once the flaps X are secured to the body B of the uterus U, the female patient is immediately sterile without any abdominal incisions or external scarring caused by such abdominal incisions. Over time, the flaps X will eventually adhere or otherwise become unitary with the body B of the uterus U, for example, through the natural build-up of scar tissue so that sterilization remains permanent, regardless of whether the fasteners absorb into the body.

[0022] Any of the disclosed fasteners (e.g., tacks, staples, clips, suture, etc.) may be bioabsorbable.

[0023] The various aspects disclosed herein may also be provided in connection with robotic surgical systems and what is commonly referred to as Telesurgery. Such systems employ various robotic elements to assist the clinician and allow remote operation (or partial remote operation) of surgical instrumentation. Various robotic arms, gears, cams, pulleys, electric and mechanical motors, etc. may be employed for this purpose and may be designed with a robotic surgical system to assist the clinician during the course of an operation or treatment. Such robotic systems may include remotely steerable systems, automatically flexible surgical systems, remotely flexible surgical systems, remotely articulating surgical systems, wireless surgical systems, modular or selectively configurable remotely operated surgical systems, etc.

[0024] The robotic surgical systems may be employed with one or more consoles that are next to the operating theater or located in a remote location. In this instance, one team of clinicians may prep the patient for surgery and configure the robotic surgical system with one or more of the instruments disclosed herein while another clinician (or group of clinicians) remotely controls the instruments via the robotic surgical system. As can be appreciated, a highly skilled clinician may perform multiple operations in multiple locations without leaving his/her remote console which can be both economically advantageous and a benefit to the patient or a series of patients. For a detailed description of exemplary medical work stations and/or components thereof, reference may be made to U.S. Pat. No. 8,828,023, and PCT Application Publication No. WO2016/025132, the entire contents of each of which are incorporated by reference herein.

It is to be understood, therefore, that this disclosure is not limited to the precise aspects described, and that various other changes and modifications may be effected by one skilled in the art without departing from the scope or spirit of this disclosure. Additionally, the elements and features shown or described in connection with certain aspects may be combined with the elements and features of certain other aspects without departing from the scope of this disclosure, and that such modifications and variations are also included within the scope of this disclosure. Accordingly, the subject matter of this disclosure is not limited by what has been particularly shown and described.
