This disclosure relates to hysterectomy and, more particularly, to robotic uterine manipulators.
Colpotomy, one of the final steps in a hysterectomy, requires making a circular incision in vaginal tissue to separate the uterus from the vagina with a cutting tool such as an electrosurgical instrument. This incision is typically performed with the aid of a uterine manipulator. Uterine manipulators are conventionally used during laparoscopic hysterectomy procedures to position the vagina and the cervix to facilitate separation and to enable removal of the uterus or other tissue specimens subsequent to performance of a colpotomy.
In accordance with an aspect of this disclosure, a uterine manipulator includes an elongated shaft assembly, a colpotomy cup supported on the elongated shaft assembly and a tip assembly. The tip assembly extends distally from the colpotomy cup and has a piercing tip configured to pierce tissue.
In aspects, the piercing tip may be spring loaded by a spring. The tip assembly may include an elongated tube that supports the piercing tip. The spring may be supported in the elongated tube. The piercing tip may be positioned to move relative to the elongated tube from a retracted position within the elongated tube to an extended position distally beyond the elongated tube. The spring may be operatively coupled to a drive mechanism of the uterine manipulator. The drive mechanism may be actuatable to cause the spring to expand. Expansion of the spring may cause the piercing tip to move from the retracted position to the extended position.
In accordance with another aspect of this disclosure, a uterine manipulator system includes an anchor configured to secure to a fundus, a grasper for grasping the anchor to control a position of the fundus, and a uterine manipulator. The uterine manipulator includes an elongated shaft assembly, a colpotomy cup supported on the elongated shaft assembly, and a tip assembly extending distally from the colpotomy cup and having a piercing tip configured to pierce the fundus.
In accordance with still another aspect of this disclosure, a robotic uterine manipulator system includes a robotic arm and a uterine manipulator coupled to the robotic arm. The uterine manipulator includes an elongated shaft assembly, a colpotomy cup supported on the elongated shaft assembly, and a tip assembly extending distally from the colpotomy cup and having a piercing tip configured to pierce a fundus.
Other aspects, features, and advantages will be apparent from the description, the drawings, and the claims that follow.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate aspects of this disclosure and, together with a general description of this disclosure given above, and the detailed description given below, serve to explain the principles of this disclosure, wherein:
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 used herein, the term “distal” refers to that portion of structure farther from the user, while the term “proximal” refers to that portion of structure, closer to the user. As used herein, the term “clinician” refers to a doctor, nurse, or 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 the present disclosure in unnecessary detail.
Robotic surgical systems have been used in minimally invasive medical procedures and can include robotic arm assemblies. Such procedures may be referred to as what is commonly referred to as “Telesurgery.” Some robotic arm assemblies include one or more robot arms to which surgical instruments can be coupled. Such surgical instruments include, for example, electrosurgical forceps, cutting instruments, staplers, graspers, electrocautery devices, or any other endoscopic or open surgical devices. Prior to or during use of the robotic surgical system, various surgical instruments can be selected and connected to the robot arms for selectively actuating end effectors of the connected surgical instruments. Some of these surgical instruments utilize electrical energy, for example, to effectuate electrocautery.
With reference to
Robotic colpotomy system 10 further includes an energy source such as an electrosurgical generator 50 that couples to uterine manipulator 100 and/or any number of other surgical instruments such as an electrosurgical probe or an electrocautery blade 60 via an electrosurgical cable 99 and a connector assembly 104 supported by sterile interface module 40 and/or proximal housing assembly 102 of uterine manipulator 100. For a more detailed description of one example of an electrosurgical generator, reference can be made to U.S. Pat. No. 8,784,410, the entire contents of which are incorporated by reference herein. For a more detailed description of one example of connector assembly 104, reference can be made to U.S. Patent Application No. 62/823,036, filed Mar. 25, 2019, and entitled “Robotic Surgical Systems with Electrical Switch of Instrument Attachment,” the entire contents of which are incorporated by reference herein. For a more detailed description of one example of an electrocautery blade 60, reference can be made to U.S. Pat. No. 8,128,622 or 8,460,289, the entire contents of each of which are incorporated herein by reference.
Robotic colpotomy system 10 employs various robotic elements to assist the clinician and allow remote operation (or partial remote operation) of surgical instrumentation such as uterine manipulator 100. Various robotic arms, gears, cams, pulleys, electric and mechanical motors, etc. may be employed for this purpose and may be designed with robotic colpotomy system 10 to assist the clinician during the course of an operation or treatment, and which can be included with, and/or part of one or more drive mechanisms 106 of uterine manipulator 100, sterile interface module 40, and/or instrument drive unit 30. 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.
Robotic colpotomy system 10 includes a medical work station (not shown) that may be employed with one or more consoles positioned 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 robotic colpotomy system 10 with uterine manipulator 100 while another clinician (or group of clinicians) remotely controls uterine manipulator 100 via the one or more consoles. As can be appreciated, a highly skilled clinician may perform multiple operations in multiple locations without leaving his/her remote console. This can be 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.
With continued reference to
Robotic surgical system 10 can be in the form of an electrosurgical colpotomy system. In general, components of the electrosurgical colpotomy system can be used to effectuate a colpotomy. Briefly, when using a uterine manipulator for colpotomy during a laparoscopic hysterectomy, a colpotomy cup can be used as a backstop for a clinician to circumferentially cut along with a laparoscopic tool (e.g., radiofrequency or “RF” tool) around the uterus. To make such a circumferential cut uniform, the clinician is required to determine the location of a rim of the colpotomy cup. Indeed, to identify the exact location of the rim, the clinician may be required to repeatedly move the uterine manipulator as the cut is made. This movement can be cumbersome and/or time consuming, particularly when clinician must also coagulate and transect uterine arteries in order to minimize blood loss during the colpotomy.
With reference to
In aspects, although described herein in connection with spring-loaded structure, piercing tip 132 can be actuated via any suitable electrical and/or mechanical structure for moving piercing tip 132 relative to elongated tube 131 (e.g., threaded rotation, cable actuation, magnetics, etc.).
Certain anatomy may be difficult to manipulate solely with a uterine manipulator. Thus, as seen in
Further, although detailed herein with respect to a robotic system, the disclosed uterine manipulators can be provided as manual and/or hand-held instruments.
