FIELD OF THE DISCLOSURE
This application relates to surgical devices that can be inserted through a laparoscopic trocar or open incision and fastened inside the body to move, hold, retract and position tissues, organs and/or instruments in order to enhance a surgeon's ability to perform an operation.
BACKGROUND ART
Advances in surgical procedures are shifting to smaller incisions resulting in quicker recoveries with better post-operative results. The most recent technology genre which has emerged is laparoscopic and robotic surgery, where small access holes called ports are placed through the abdominal cavity and instruments are inserted through these ports to perform surgery. These procedures are performed under visual observation using small cameras.
Currently, laparoscopic retracting and positioning devices are controlled by the surgeon and/or assistant through working ports. These devices are quite useful yet they share several important limitations. They monopolize a port. They are limited by their inherent lack of flexibility which is dictated by a straight line trajectory starting at the port and ending at the organ or tissue structure. Finally, they often obstruct the surgeons operating view or compete for intra-abdominal space with other surgical instruments. All of these limitations can potentially complicate or lengthen a surgical procedure.
SUMMARY OF THE DISCLOSURE
To address the abovementioned limitations, we propose a novel device that will position and retract organs and tissues during surgery without tying up a laparoscopic trocar. It will not interfere or compete for space in the limited intra-abdominal cavity. The device will be secured to the intra-abdominal wall by a suture passed though the abdominal wall to an exterior stabilizing device. The device does not require a dedicated port. It requires no dedicated skin incisions as the intra-abdominal components can be passed into the abdominal cavity through existing ports. The device has grasping, retracting, imaging and visual capabilities. The device has the potential to reduce surgery time, reduce skin incisions and port usage, improve surgical visibility, allow for ultrasound imaging or novel camera angles for better visibility, improve the intra-operative conditions to perform a procedure, allow easier surgical access to difficult locations in surgery.
The device can also be used in open surgery. Benefits include retraction and stabilization from an area outside of the main retractor. This can benefit the surgeon by decreasing the attachments to the main retractor thereby increasing the space available for the surgeon and assistant to complete a given surgery. In addition, the novel angel of retraction away from the main open incision offers the surgeon increased flexibility for retraction or stabilization of organ structures.
The anvil handle medical probe consists of a straight graspable anvil along with one or two trailer balls on either end. The instrument is best suited for laparoscopic and robotic surgery but can be used in other applications. It offers more flexibility and control for physicians when trying to manipulate laparoscopic tools. The anvil handle allows the laparoscopic instruments or the tentacles of the Surgical Octopus to grasp items in multiple ways i.e. from one side, from both sides, or from the top, front or rear. It can be attached to numerous medical devices such as ablative devices, intra-operative ultrasound imaging probes, remote cameras, or internal positioning devices. The handle may be customized to fit existing devices.
The anvil handle (anvil) allows a medical device such as an intra-operative drop in ultrasound probe or camera to be grasped quickly and securely from any direction to better complete a surgical task. In addition, the anvil allows for additional accessory handles to be used in other applications.
OBJECTIVES
Objective number one is to provide an intraoperative base plate with movable adjustable arms to hold and position tissues, organs and/or instruments
According to an embodiment, a device is provided which can be passed through a 10 mm or 12 mm trocar and assembled by the surgeon inside the cavity of the body during surgery.
The device is secured to the abdominal wall and is used to retract organs and tissues to allow the surgeon better visibility and accessibility during a surgical procedure.
The device is comprised of several parts depending on the needs of the surgeon. The device can be anchored or free-floating dependent on the type of operation.
The device consists of a base plate, anchoring system and one or more articulating arms which can be positioned and anchored to a desired configuration.
In addition, the articulating arms can accommodate various devices to hold and manipulate tissues or instruments.
An accessory channel allows for vacuum or pressure to inflate expansion devices or suction to attach the articulating device to specified tissue. Additional embodiments include signal or low power energy to operate other devices such as intraoperative cameras.
The anchoring system is passed through an accessory port and once expanded is attached to the abdominal wall with a suture or other method, in a location by using physician preferences.
The positioning arms or accessories are then passed through a port and attached to the base anchor. They are then manipulated using laparoscopic or robotic instruments during laparoscopic surgery, or via direct manipulation during an open procedure. Once in place a locking device is activated, and the arms will remain locked until the physician releases the locks.
The arms can be easily relocated or repositioned by simply releasing the locks, repositioning the arms and then relocking
During surgery additional devices can be passed through ports and attached to other areas of the anchoring system as needed.
Instrument clips with the Anvil attachment can be used to secure devices such as ultrasounds or cameras or other laparoscopic devices
Objective number two of this invention is to provide an attachment that can be used on laparoscopic equipment and surgical tools that allows for quick and easy attachment and detachment of surgical implements and can be incorporated in a fixed design on diagnostic equipment or therapeutic devices. or incorporated in a clip attachment.
This quick connect device further adds to the ease of operation with both anvil and ball (or all three) as optional attachments to a probe. This allows for easier manipulation of intra-abdominal surgical devices and tools. The addition of an optional “trailer ball” offers the physician the option to move a probe and device and/or apply pressure to the device in off plane axes using two laparoscopic instruments
Objective number three of this invention is to allow doctors performing intra-abdominal robotic surgery to complete surgeries quicker by allowing them to quickly grip and move surgical tools more easily.
The removable clip attachment with anvil attached permit accessories to be grasped in multiple positions. The anvil handle offers numerous ways to grasp the medical device quickly and securely.
Accessory Handles can be quickly attached allowing for a quick transition from the laparoscopic table, to robot or laparoscopic control to an open procedure quickly, as needed.
