摘要： An improved stabilizer or retractor or other surgical tool having an elongated distal arm carrying a tissue-contacting mechanism at its distal end and a tensioning mechanism at its proximal end for locking functional components of the tool in a desired position or configuration. The tensioning mechanism is mounted to a turret or other structure attaching the distal arm to a base by means of a shorter, proximally extending flexible arm. The flexible proximal arm allows the tensioning mechanism to be moved relative to the base so that it can be placed more conveniently in the operative field.

摘要： An adjustable retractor is disclosed comprising an inner ring, an outer ring spaced from the inner ring, and an elongate sleeve open at opposite ends. The sleeve is provided and extends between the inner and outer rings and is connected at the opposite ends to the rings. The outer ring is provided with a pre-loaded rotational torque to assist with rotation of the outer ring about its central axis to roll the sleeve about the outer ring to adjust sleeve length. The outer ring may be formed in a mobius configuration to provide the pre-loaded rotational torque. The outer ring has a cross-sectional shape that may have numerous different configurations. The mobius configuration may include the cross-sectional shape having an outer circumference offset by a predetermined amount about the central axis of the outer ring proceeding longitudinally along the central axis from one location on the outer ring to another location on the outer ring. A method of adjusting a retractor is also disclosed.

摘要： A retractor and a surgical tool are positioned within a cannula, and a dissection cradle of the retractor is positioned at the distal end of the cannula. The retractor includes a first portion with an axis approximately parallel to the axis of the cannula and a second portion with an axis skewed relative to the axis of the cannula. The dissection cradle may include two substantially parallel, spaced legs with the retractor shaped in a loop between and in a plane skewed relative to the axes of the legs, and with the loop directed away from the surgical tool. Thus, in operation, when a surgeon locates a vessel and side branch of interest, the surgeon extends the retractor to cradle the vessel in the dissection cradle. Once cradled, the retractor may be fully extended to urge the vessel away from the axis of the cannula to isolate the side branch for exposure to a surgical tool. One of the legs supporting the retractor is hollow and includes a spray nozzle disposed in the distal end of the retractor to form an irrigation system The proximal end of the hollow leg communicates with a fluid inlet which receives irrigation fluid under pressure for washing the endoscope lens. The spray nozzle on the retractor may be positioned to wash the endoscope lens, or upon selective extension of the retractor out of the cannula, the spray nozzle may be positioned to direct the spray of irrigation fluid at a remote surgical site.
摘要翻译：牵开器和手术工具定位在套管内，并且牵开器的解剖支架位于套管的远端。牵开器包括具有大致平行于套管轴线的轴线的第一部分和具有相对于套管轴线倾斜的轴线的第二部分。解剖支架可以包括两个基本上平行的间隔开的腿，其中牵开器成形为环绕在相对于腿的轴线倾斜的平面之间的环中，并且环路指向远离手术工具。因此，在操作中，当外科医生定位感兴趣的血管和侧分支时，外科医生将牵开器延伸到将解剖支架中的血管摇动。一旦收起，收缩器可以完全延伸以促使血管远离套管的轴线，以隔离侧分支以暴露于手术工具。支撑牵开器的一个腿是中空的，并且包括设置在牵开器的远端中的喷嘴以形成冲洗系统。中空腿的近端与在压力下接收冲洗流体以洗涤内窥镜镜片的流体入口连通。牵开器上的喷嘴可以被定位成洗涤内窥镜镜片，或者在将牵开器选择性地延伸出套管之后，可以将喷嘴定位成将冲洗流体喷射在远程外科手术部位。

摘要： A stabilized cephalic medical apparatus includes an annular band for placement around a patient's head, and a pivotally adjustable bridge member for holding and supporting a medical instrument. The bridge member according to the invention is attachable to the annular band, and is preferably removable therefrom for cleaning and sterilization thereof. The bridge member is preferred to include a mounting member for supporting a medical instrument thereon, and a connector for connecting the mounting member to the annular band. The apparatus may further include a medical instrument attachable to the bridge member. The design of the apparatus according to the invention allows a medical instrument, such as a nasal speculum or retractor, to be operatively attached to, and to move concurrently with the patient. Attachment of the medical instrument to a patient tends to minimize or eliminate complications arising from movement of a patient's head with respect to a fixed in place speculum, retractor, or other medical instrument. A method of using the apparatus in connection with a medical instrument is also described.

摘要： A surgical retractor includes a frame and hinges associated with the frame for making the frame conformable to the chest or other anatomical structure of a patient. Retractor blades are operatively associated with the frame for retracting soft tissue or bone structure. Where the surgical retractor includes opposing pairs of retractor blades for retracting soft tissue or bone structure in two relatively generally perpendicular directions, a method of using the device includes making an incision in the skin of a patient, placing the device over the incision, using one opposing pair of retractor blades to retract skin and soft tissue in a first direction and using the second opposing pair of retractor blades to retract bone in a second direction, the second direction being generally perpendicular to the first direction.

摘要： An inflatable retraction apparatus is provided for retracing an organ inside a body to gain access to an adjacent tissue. The apparatus includes an able chamber formed from a single thin envelope, and capable of being collapsed for insertion through an incision and being expanded to a predetermined shape for retracing the organ. An inflation mechanism is adapted to selectively inflate the chamber to the predetermined shape. The inflation mechanism includes at least one inflation tube attached to the inflatable chamber in fluid communication theretween, and an inflatable maintaining lattice operatively enveloping the inflatable chamber and in operative association with the inflation mechanism. The inflatable maintaining lattice defines a plurality of single layered access windows around the inflatable chamber, and is configured and adapted to maintain the inflatable chamber in substantially the predetermined shape after an aperture is pierced in at least one of the plurality of access windows of the inflatable chamber.
