A surgical robot mechanism with single-port and multi-port minimally invasive surgery functions includes: a bracket; and a manipulator connected to the bracket, and supported by the bracket, the manipulator includes: a support arm movable along the bracket; a function conversion frame fixed on the support arm and configured for the surgical robot mechanism to switch between a single-port minimally invasive surgery mode and a multi-port minimally invasive surgery mode; a plurality of posture adjustment arm assemblies connected to the function conversion frame, each posture adjustment arm assembly configured to adjust a position and posture of a surgical tool connected thereto for performing a surgical operation.

An instrument access device of a teleoperated surgical system includes an envelope, a clamp, and a plurality of ports. The envelope includes a distal opening and a cavity. The clamp is in the distal opening of the envelope. The plurality of ports are coupled to the envelope. The plurality of ports are proximal to the clamp and the distal opening of the envelope. Each of the plurality of ports includes a seal, which is sized and shaped to seal an outer surface of a cannula and to fix a position of the cannula relative to the port and the envelope.

Systems and methods for preventing the seeding of cancerous cells during morcellation of a tissue specimen inside a patient's body and removal of the tissue specimen from inside the patient through a minimally-invasive body opening to outside the patient are provided. One system includes a cut-resistant tissue guard removably insertable into a containment bag. The tissue specimen is isolated and contained within the containment bag and the guard is configured to protect the containment bag and surrounding tissue from incidental contact with sharp instrumentation used during morcellation and extraction of the tissue specimen. The guard is adjustable for easy insertion and removal and configured to securely anchor to the body opening. Protection-focused and containment-based systems for tissue removal are provided that enable minimally invasive procedures to be performed safely and efficiently.

A uterine fibroid tissue removal device includes an inner tube disposed within an outer tube and configured to be translated and rotated relative to the outer tube, and a separately formed unitary distal tip member attached to a distal end of the inner tube, such that the distal tip member translates and rotates relative to the outer tube along with the inner tube, wherein a distal facing open cutting end of the distal tip member in fluid communication with an axial lumen of the distal tip member translates across a tissue resection window in a sidewall of the outer tube so as to sever tissue extending therethrough, the distal tip member axial lumen being in fluid communication with an axial lumen of the inner tube, wherein an outer diameter of the distal tip member is greater than an outer diameter of the inner tube.

Embodiments of a surgical access port system that comprises a retractor that is adapted for being coupled to a cap and that is particularly useful in natural orifice surgery are described. The retractor comprises an outer ring, wherein the outer ring is configured to be disposed proximate the natural orifice of the patient and substantially surround the orifice; a tubular body; and various stabilizing mechanisms surrounding the tubular body, sized and configured to stabilize and retain the retractor within the orifice. The stabilizing embodiments described herein are useful in all natural orifices and are of particular use in the vaginal surgery.

The invention provides a pneumatic sealing system device which allows sealing a working channel, a surgery multichannel device comprising a pneumatic sealing system and a method for installing said pneumatic sealing system on a multichannel device. The device is a mentioned instruments simultaneously.

Provided is an integrated monitoring and management system for endoscopic surgery, in which the system simultaneously monitors and manages the surgical environment such as pressure, temperature, humidity, smoke, and the like inside the human body, and the type and access of surgical instruments used for surgery throughout the surgical procedure at the time of endoscopic surgery, such that an optimal surgical environment is maintained according to a monitoring result, and when an accident occurrence factor is monitored during the surgical procedure, it is possible to prevent an accident from occurring by informing of the accident occurrence factor, and it is possible to quantify a safe and successful surgical procedure by analyzing accumulated big data.

The tissue removal containment system is provided that includes a tissue removal and/or containment bag arranged to be inserted through an opening into a confined space. The bag has a support or ring having a compressed, partially compressed and/or uncompressed state or position. The bag can also include an enclosure or film defining the enclosure connected to the support with the enclosure having a confined state and a deployed or unconfined state.

An apparatus for providing instrument access through a gel pad of a surgical access device disposed to seal an opening to a body cavity of a patient is disclosed. The apparatus includes a stem having a bore extending therethrough, the stem having a length sufficient such that when the stem is inserted through the gel pad a distal end of the stem protrudes beyond an inner surface of the gel pad. The bore is sized to permit an instrument to be inserted through the bore and through the opening into the body cavity. The stem includes a flanged opening to the bore that remains external to an outer surface of the gel pad and limits the insertion of the stem through the gel pad. The apparatus also includes a displaceable seal disposed within the bore below the flanged opening, the displaceable seal being operable to seal the bore prior to insertion of the instrument and to displace to permit insertion of the instrument while maintaining the seal.

This disclosure is relative to the field of laparoscopic surgery and gynecologic surgery. Specifically disclosed is a surgical technique for laparoscopic hysterectomy and bilateral salpingectomy-oophorectomy which encompasses dissection and removal of the uterus, fallopian tubes, and ovaries. The technique utilizes a single-entry port located at the umbilicus in conjunction with access through the vaginal opening to access and manipulate the organs within the abdominal cavity.
