摘要： A Multiple Aperture Ultrasound Imaging (MAUI) probe or transducer is uniquely capable of simultaneous imaging of a region of interest from separate physical apertures. Construction of probes can vary by medical application. That is, a general radiology probe can contain multiple transducers that maintain separate physical points of contact with the patient's skin, allowing multiple physical apertures. A cardiac probe may contain only two transmitters and receivers where the probe fits simultaneously between two or more intracostal spaces. An intracavity version of the probe can space transmit and receive transducers along the length of the wand, while an intravenous version can allow transducers to be located on the distal length the catheter and separated by mere millimeters. Algorithms can solve for variations in tissue speed of sound, thus allowing the probe apparatus to be used virtually anywhere in or on the body.
摘要翻译：多孔超声成像（MAUI）探针或换能器独特地能够从单独的物理孔径同时成像感兴趣区域。探针的构建因医疗应用而异。也就是说，一般放射学探针可以包含多个换能器，其保持与患者皮肤分开的物理接触点，允许多个物理孔径。心脏探针可以仅包含两个发射器和接收器，其中探针同时在两个或更多个腔内空间之间配合。探针的腔内版本可以沿着棒的长度放置发射和接收换能器，而静脉内的形式可以使换能器位于导管的远端长度上并且分开仅仅毫米。算法可以解决声音组织速度的变化，从而允许探针设备实际上用于身体内部或身体的任何位置。

摘要： Surgical treatment of tissue includes electrocauterization of blood vessels interposed between spaced sets of electrodes of opposite polarity, and includes transection of such tissue by a cutter that is mounted between the spaced sets of electrodes for translational and lateral movement relative to the sets of electrodes. Orientations of the sets of electrodes within a range of angles about an elongated axis of a supporting body are controlled by manual movement of an actuator mounted near a proximal end of the body for movement through a smaller range of angles via linkage connecting the actuator to the electrodes. Tissue dissection with gas insufflation to form an anatomical space in tissue is facilitated by a fluid outlet port located near the tissue-dissecting tip at the distal end of the elongated body that delivers through the tissue-dissecting tip to the dissected tissue a fluid under pressure that is supplied along a lumen within the elongated body.

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 dissection cradle that is resiliently supported along an axis skewed relative to the axis of the cannula. The dissection cradle, in operation, is extended to cradle the target vessel, and the retractor may be fully extended to urge the vessel away from the axis of the cannula to isolate a side branch for exposure to a surgical tool. The retractor includes a hollow support and a spray nozzle disposed in the distal end of the retractor to form an irrigation system and lens washer that can be selectively positioned to direct the spray of irrigation fluid at a remote surgical site or at an endoscopic lens.

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： 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 at an angle to the axis of the cannula. The dissection cradle is located at the distal end of the second portion of the retractor, and may include two substantially parallel, spaced legs with the retractor shaped in a loop between and in a plane skewed relative to the axis of the legs, and with the loop directed away from the surgical tool. Thus, in operation, when the surgeon locates a vein and side branch of interest, the surgeon extends the retractor to cradle the vein in the dissection cradle. Once cradled, the retractor may be fully extended to urge the vein away from the axis of the cannula isolate the side branch for exposure to the surgical tool. In another embodiment, the cannula includes a sheath which encases the curved, resilient retractor at a first position to retain the retractor in substantially straight orientation, and which encases the retractor at a second position that allows the retractor to extend at an angle relative to the axis of the cannula.

摘要： A lifting apparatus for deployment through a laparoscopic incision in a body wall to apply an external lifting force over a large area of the body wall. The apparatus provides a broad lifting surface that is capable of applying a lifting force of at least 40 pounds (180 Newtons) to an area of a body wall sufficiently extensive to reduce the lifting pressure exerted on the body wall to well below that which could cause pressure trauma to the body wall, yet delivers this broad lifting surface through the body wall via an incision about 14 mm long. The apparatus comprises a body wall engaging element capable of passing in a packaged state through the laparoscopic incision, and being inflatable to an inflated state. In the inflated state, the body wall engaging element is substantially toroidal, provides a broad lifting face, and bounds a central hole. The body wall engaging element includes an equatorial portion facing into the central hole. The apparatus also includes a flexible lifting element that has a flexible portion capable of passing through the laparoscopic incision. The flexible portion is attached to the equatorial portion of the body wall engaging element and extends from the equatorial portion towards the broad lifting face. The flexible lifting element also includes an adapter, connected to part of the flexible portion remote from the equatorial portion of the body wall engaging element, that receives the external lifting force and transfers the external lifting force to the flexible portion.

摘要： Described herein are devices for reversibly constraining an endoscope. Such devices may comprise: a base positionable proximate a patient; a column extending vertically from the base; an arm extending horizontally from the column; and a clamp coupled to the arm. In some embodiments, the clamp comprises a holder comprising an annular ring defining an endoscope receiving area or a first sidewall and a second sidewall together defining an endoscope receiving area. The holder is transitionable between a first configuration in which the annular ring or the first and second sidewall are configured to set apart from an endoscope in the endoscope receiving area and a second configuration in which the annular ring or the first and second sidewall are configured to clamp the endoscope in the endoscope receiving area.
