A method of facilitating access to a neonate through a caesarean incision in the woman's abdomen by opening the incision, includes providing a supporting ring dimensioned to allow delivery of a neonate through the ring and comprising a non-adjustable pelvic-region retractor and handle fixed to the supporting ring and articulating the supporting ring to insert the non-adjustable pelvic-region retractor into the incision to cover and hold back the woman's bladder with the supporting ring disposed over the woman's abdomen. A first adjustable saddle-shaped retractor is then inserted into the incision to cup a first section of abdominal tissue on an abdominal side of the incision, before attaching the first adjustable saddle-shaped retractor to the supporting ring while it is cupping the first section of abdominal tissue at a first position spaced apart from the non-adjustable pelvic-region retractor to anchor the supporting ring to the woman and partially open the incision.

Provided herein are expandable devices, rail systems, and motorized devices. In one embodiment, an expandable device comprises an expandable sac having a tool housed therein. The expandable device is optionally configured for operation while inside a body cavity. The expandable device optionally comprises at least one rail in the sac, and at least one railed device coupled to the rail for movement there on. Movement of the railed device on the rail is provided by, for example, a motor such as an electromagnetic motor or an inch-worm type motor. Expandable devices can be used, for example, to perform minimally invasive medical procedures requiring access to a body cavity. Expandable devices can also be used, for example, to provide safe and stable transport of instruments to the body cavity.

The present invention provides a retraction device comprising, a shaft, a plurality of arms supported by the shaft, the arms being configured to be moveable between a first orientation in which the device assumes an insertion profile for passage of the device through a surgical incision, and a second orientation in which the device assumes a retraction profile. At least one of the plurality of the arms is adapted to be adjustable between a first length and a second length.

A surgical access system includes a cannula assembly and an obturator assembly. The obturator assembly provides an insufflation channel or fluid passage for delivery of insufflation fluids directly to an underlying cavity, e.g., the abdominal cavity. The fluid passage is completely confined within the obturator assembly isolated from the cannula assembly and terminates at a location distal of the cannula assembly such that the insufflation fluids released from the fluid passage are directed toward the abdominal cavity and not within the cannula assembly.

The present invention provides a method of repairing a defect in an abdominal wall of a subject, including the steps of: making a small incision through a skin layer above the defect in the abdominal wall, introducing a surgical device including a deformable body through the incision to reach a preperitoneum underlying the abdominal wall around the defect, using the surgical device to identify a protruded region of the preperitoneum extending towards the abdominal wall around the defect, and flattening the protruded region of the preperitoneum and separating the protruded region of the preperitoneum from the abdominal wall with the deformable body in an expanded condition. The method results in low recurrence of abdominal wall defect, less pain, and a shorter hospital stay after surgery.

A trocar set includes a handle portion, a first sleeve, a second sleeve, and a gasbag. The handle portion includes a grip, a connection part, and a first gas valve. The connection part extends from the grip and includes an assembling channel. The first gas valve is connected to the connection part and communicates with the assembling channel. An assembling end of the first sleeve is assembled to the connection portion. A sleeving end of the first sleeve is provided with a first opening. The second sleeve is retractably connected to the sleeving end of the first sleeve. A sleeve wall of the second sleeve is provided with a second opening. The gasbag is connected to an end of the second sleeve away from the sleeving end and corresponds to the second opening. The design of the retractable sleeves is benefit to perform operation.

A method includes providing an indwelling tool having a magnetic body at the inside of a luminal organ by inserting the tool into a working channel inserted from a natural opening of a living body to the luminal organ, in a manner such that an axis along a length of the magnetic body is arranged substantially parallel to a length direction of the working channel; disposing the tool in a vicinity of a diseased part of the luminal organ; applying a magnetic field to the magnetic body by using a magnetic field generating device provided at the outside of the luminal organ, so as to attract the magnetic body and make a side face of the magnetic body along the axis thereof push against a tissue in the vicinity of the diseased part; and lifting a tissue around a position of the tool, which includes the diseased part, by applying a magnetic force to the magnetic body by using the magnetic field generating device.

A device for producing a pneumoperitoneum in a medical procedure includes a main body having a ring portion defining a main opening, and a domed portion extending from the ring portion to an apex. The ring portion is adapted to form a positive seal with the skin of the patient upon application of a suction force within the main body abutting the patient. The device includes a suction port extending from the domed portion of the main body and is configured to facilitate application of the suction within the main body. The access port is operably engaged with the domed portion of the main body proximate to the apex and is adapted to receive a surgical instrument therethrough. A pair of opposed grips operably engaged with the domed portion of the main body is adapted to facilitate one-handed application and removal of the main body with respect to the patient.

A hernia repair device, comprising: an inflatable balloon having an inflation tube, the inflation tube having a proximal end attached to said balloon and a distal end adapted to be extracted from the body, separately from the balloon, via an opening which is smaller than a laparoscopic opening, and a mesh removably attached to said balloon, wherein the inflation tube passes through the mesh.

A method of manipulating patient tissue with a surgical device that provides a suction force against a patient's body. The device includes a handle and a suction head pivotally attached to the handle. The suction head includes an open-ended suction chamber having a rim positioned to engage the patient's skin. An actuator on the handle operates a pump to draw a negative pressure in the suction chamber, causing the rim to seal against the patient's skin via the suction force. Once the suction force is initiated, the user may lift the handle away from the patient's body to lift tissue. The lifted tissue provides a site for insertion of a trocar or Veress needle for a laparoscopic procedure in some embodiments. A gimbal disposed between the handle and the suction head provides at least two degrees of freedom such that the handle can be rotated and pivoted to optimize the direction of applied lifting force.
