Specific Use Retractor Patents (Class 600/235)
  • Patent number: 10898176
    Abstract: A surgical site retractor is configured to retract tissue, such as in an intercostal procedure. The retractor may be formed from non-radiopaque material for improved monitoring via x-ray imaging. The retractor may have a rigid retractor and a soft tissue retractor, where the rigid retractor has a plurality of legs and the soft tissue retractor extends between the legs to prevent soft tissue from extending between said legs. The retractor may have a bendable arm with an implement holder, such as distal cuff or clip adapted to resiliently hold an implement such as a tube of an elongated port-access device. A method involves partly installing the surgical site retractor, expanding the surgical site retractor, deploying the surgical implement from outside the body through the incision and into the patient, resiliently capturing the implement with the holder of the arm, and bending the arm to hold the implement in a desired position.

  • Patent number: 10251634
    Abstract: A scleral depressor includes an elongated handle defining a first axis. An extension member has one end attached to the proximal end of the handle and includes a blade at the remote end thereof. The extension member defines a second axis and extends from the handle at approximately 90° thereby defining a plane. A bulbous or cylindrically shaped blade located at the remote end of the extension member has its rounded surface extending out of the plane. By properly manipulating the handle, such as by rotating the same, the rounded surface of the blade is used to depress the sclera.

  • Patent number: 10080558
    Abstract: A device, providing enlargement and preventing collapse, of the pupil of the eye, during an ophthalmic surgical procedure. The device, configured as a continuous or discontinuous ring, comprises plurality of notches at corners and flanges at sides. The ring is formed from a strand of resiliently flexible material and is disposed entirely within a single plane. The notches engage the pupillary margin at different parts, pushing them apart, resulting in sustained enlargement of the pupil. In addition, the device causes bending of the pupillary margin and iris at the notches and above and below the flanges, resulting in a secure engagement. The enlarged pupil created by the ring, allows a wide view of the structures deeper to the pupillary plane, previously obscured due to a small pupil.

    Abstract: A vaginal manipulator includes a shaft attached to a head and a door connected to the head. The head has an anterior side opposite a posterior side and includes a core fixed to the shaft and a sleeve coupled in a sliding relationship to the core. The door is coupled to the core and is movable relative to the posterior side of the head through an opening provided in the sleeve. A proximal end of the core defines a proximal end of the head and a distal end of the sleeve defines a distal end of the head. The proximal end of the core is fixed to the shaft. The sleeve moves relative to the core to provide the head with an adjustable length between the proximal end of the head and the distal end of the head.

  • Patent number: 8808173
    Abstract: In a pericardioscopic procedure, without providing an endoscope or surgical instrument with special space ensuring means and without unnecessarily dilating the pericardial space, a space necessary for operation of the endoscope or surgical instrument is ensured, so that maneuverability is improved while suppressing complications. Provided is a space ensuring device comprising: a pericardium pressing part for pressing a pericardium from the pericardial space side; a heart pressing part for pressing the surface of a heart from the pericardial space side; and an interconnecting part interconnecting the pericardium pressing part and the heart pressing part, wherein the interconnecting part generates the resilient force enabling expansion against a pressure applied by a pericardium and a heart so as to ensure a space between the pericardium pressing part and the heart pressing part.

  • Patent number: 8753266
    Abstract: A heart retractor links lifting of the heart and regional immobilization which stops one part of the heart from moving to allow expeditious suturing while permitting other parts of the heart to continue to function whereby coronary surgery can be performed on a beating heart while maintaining cardiac output unabated and uninterrupted. Circumflex coronary artery surgery can be performed using the heart retractor of the present invention. The retractor includes a plurality of flexible arms and a plurality of rigid arms as well as a surgery target immobilizing element. One form of the retractor can be sued in minimally invasive surgery, while other forms of the retractor can accommodate variations in heart size and paracardial spacing.

  • Publication number: 20140148654
    Abstract: The present invention relates to a method and device for removing solid matter from a brain and controlling bleeding associated with the removal of the matter. The method involves securing a cranial anchor to a region of the skull in which an opening has been created to expose brain matter and introducing through a passage defined by the anchor a channel member that displaces brain tissue and exposes the solid matter. After removing the solid matter, a flowable hemostat is introduced into the cavity created by removal of the matter. A balloon introduced into the working channel is then inflated to compress the hemostat against the wall of the cavity to control bleeding from blood vessels around the cavity. The device includes a cranial anchor, a channel member defining a working channel, an optional removable trocar, and a catheter for introducing the hemostat and the inflatable balloon into the cavity.

  • Publication number: 20140107426
    Abstract: Less invasive surgical techniques for performing brain surgery are disclosed in which a dilating obturator and cannula assembly is inserted into brain tissue until the obturator tip and cannula are adjacent to the target tissue. The obturator is removed and surgery is performed through the cannula. In preferred embodiments the obturator and cannula are placed using image guidance techniques and systems to coordinate placement with pre-operative surgical planning. A stylet with associated image guidance may be inserted prior to insertion of the obturator and cannula assembly to guide insertion of the obturator and cannula assembly. Surgery preferably is performed using an endoscope partially inserted into the cannula with an image of the target tissue projected onto a monitor. Dilating obturator structures having a rounded or semi-spherical tip and/or an optical window for visualizing brain tissue during expansion are contemplated.
