A method of electrically grounding a medical instrument includes inserting a medical instrument through a channel of a surgical port extending from a first end of the surgical port to a second end of the surgical port and while the medical instrument is inserted through the channel, contacting the medical instrument with an electrically conductive material portion protruding into an interior of the channel and extending through a sidewall of the surgical port. Contact of the medical instrument with the electrically conductive material portion does not extend around an entire circumference of the medical instrument.

A valve component 1 of the invention comprises a main valve 2 which is located on a centre line and at least one auxiliary valve 3 which is located radially outwardly of the main valve 2. The main valve may be used for sealing engagement with a cannula. In some cases the cannula may be used for introduction of a number of robotically controlled surgical instruments generally, including a camera. The auxiliary valves 3 may be utilised to introduce another instrument through the valve component. The valve component is mounted in a manner which ensures that the valve component 1 is rotatable about a centre line through the axis of the valve component 1. This ensures that the valve component 1 can be rotated relative to a cannula inserted through the main valve 2 and consequently that the auxiliary valves 3 are rotatable relative to the cannula allowing the auxiliary valves 3 to be positioned to facilitate optimum access and manipulation for an auxiliary instrument(s) inserted through the auxiliary valve(s) 2.

The present invention relates to a protective nasal mask device which hermetically seals the nasal region of a user during an ENT procedure. The device facilitates access to the user's nose and throat using a plurality of surgical tools. The primary advantage of the present invention is to provide a nasal mask device which protects medical professionals from disease transmission during an ENT procedure. Additional advantages include a nasal mask device which enables usage of a plurality of surgical tools during an ENT procedure, a device which at the same time, prevents exposure of biohazardous waste to medical professionals. The device hermetically seals the nasal region of a patient during an ENT procedure.

A protection device for transoral surgery includes: a main body configured to be fitted into an oral cavity of a human body and to expand a mouth vestibule between teeth and a lip of the human body; and at least one insertion device provided to the main body and having a through hole formed therethrough to enable insertion of a trocar required for a surgery. The main body includes: a tooth coupling part configured to be fitted on the teeth of the human body; an expansion part to be disposed on an outside of the tooth coupling part and configured to expand the mouth vestibule to allow the teeth and the lip to be spaced apart from each other; and an extension part configured to connect the tooth coupling part and the expansion part.

A surgical assisting device for use in a surgical procedure. The surgical assisting device comprises a flexible wall configured to form a chamber capable of assuming a volume larger than 500000 mm3. The surgical assisting device further comprises a closable wall port placed in a first portion of the flexible wall and forming a closable port for transfer between the chamber and the ambient environment, and a closable body port placed in a second portion of the flexible wall and configured to be connected to an incision in the body of the patient and forming a closable port for enabling transfer between the chamber and a cavity in the body of the patient, during the surgical procedure. The chamber has a first volume when the wall port and the body port is at a first distance from each other, and a second smaller volume when the wall port and the body port is at a second, shorter distance from each other.

A method of suturing a trocar path incision in a tissue of a patient with an obturator includes inserting the obturator through the tissue such that a shaft of the obturator extends through a tissue opening about the trocar path incision and a distal tip of the obturator is positioned within a cavity of the patient. The method also includes directing the suture via a suturing feature with the obturator inserted through the tissue in order to direct the suture relative to the tissue. Furthermore, the method includes closing the tissue opening about the trocar path incision with the suture.

A circumferential retractor system is provided that includes a circumferential retractor and a flexible retainer. The circumferential retractor and retainer retracts and protects a patient's body opening, providing access into a patient.

Various devices are provided for allowing multiple surgical instruments to be inserted through a single surgical access device at variable angles of insertion, allowing for ease of manipulation within a patient's body while maintaining insufflation. Safety shields and release mechanisms are also provided for use with various surgical access devices.

A medical instrument includes a handle, a trocar in communication with the handle, and a cannula in communication with the trocar and the handle. The cannula is engaged (locked) with the handle when linearly displaced proximally towards the handle and, the cannula is disengaged (unlocked) from the handle when linearly displaced distally away from the handle. The cannula is linearly reciprocated, between the locked position and the unlocked position, along a linear travel path defined parallel to a longitudinal axis of the trocar such that the cannula is prohibited and permitted to articulate about the longitudinal axis of the trocar, and relative to the handle, respectively. Advantageously, the cannula is locked and unlocked from the trocar by without requiring an external force exerted generally transverse to trocar and/or cannula, thereby permitting a user to lock/unlock the cannula, relative to the trocar, with one hand.

Surgical systems are provided. In one exemplary embodiment, a surgical system includes first and second port devices, that are each configured to be at least partially disposed within a body. The first port device includes a first housing defining a first plurality of ports each configured to allow a respective instrument of a first set of instruments to be inserted therethrough. The first port device is configured to interact with at least one respective instrument that is inserted through its respective port. The second port device is configured to interact with at least one respective instrument that is inserted through its respective port. The first and second port devices are each configured to allow at least a portion of the first set of instruments and at least a portion of the second set of instruments to work cooperatively together. Methods for using the same are also provided.
