    • An apparatus and a method are provided in which a cylindrical body is shaped and sized to sealingly and closely fit into a conventional cannula. An elongate surgical instrument is inserted into the cylindrical body through a resilient seal so as to extend past and be in pressing contact with distal ends of a plurality of bristles supported to the cylindrical body inside a distal end thereof. The sealing element and the bristles cooperate to support the surgical instrument substantially axially of the cylindrical body and the cannula within which it is contained. Relative motion of the surgical instrument causes a rubbing action of the bristles contacting its outer surface and this serves to remove any incidental surgical debris, e.g., excised tissue, coagulated fluids, and the like, from the bristle-contacted outer surface of the surgical instrument both when it is moved during use and when it is removed from the cylindrical body.
    • 提供了一种装置和方法,其中圆柱形主体的形状和尺寸被设计成密封地和紧密地配合到常规插管中。 细长的外科器械通过弹性密封件被插入到圆柱体中,以便延伸过去,并且与其支撑在圆柱体的远端内的多个刷毛的远端紧贴接触。 密封元件和刷毛协作以大致轴向地支撑外科器械,该圆柱形本体和其中包含的套管。 手术器械的相对运动导致刷毛接触其外表面的摩擦作用,这用于从手术器械的刷毛接触的外表面去除任何附带的手术碎片,例如切除的组织,凝固的流体等 当它在使用期间移动时以及当它从圆柱体移除时。

    • An endoscopic tool has an elongate cylindrical cannula with an open hooked end insertable into the body of a patient with a trocar element providing a laser powered flux of energy for precise incision and optional cauterization of tissue. A conventional pointed trocar may be used with the hooked cannula to permit forcible insertion of the hooked cannula end to the selected surgical site. In the alternative, a laser energy conveying trocar may be used with the hooked cannula or homeostatic insertion into the patient's body. The active distal end portion of the trocar may be provided with a selectively shaped energy-delivering tip element. The energy-delivering tip element may be provided with a subsurface heating region in which a selected implanted material converts received laser energy into heat for application to tissue held in the hooked open end portion of the cannula. Once the selected tissue is hooked, the surgeon may forcibly apply the heated or laser-energy emitting surface of the tip element to the tissue to be vaporized and incised. A cauterizing surface may be provided on the tip element of the trocar or, in the alternative to the hooked portion of the cannula.
    • 内窥镜工具具有细长的圆柱形套管,其具有可插入患者体内的开放钩端,套管针元件提供用于精确切口和可选择的组织烧灼的激光供能的能量通量。 常规的尖头套管针可以与钩状套管一起使用以允许将钩状套管末端强制插入所选择的手术部位。 在替代方案中,可以将激光能量输送套针针与钩状插管一起使用或者将体内平衡插入病人体内。 套管针的主动远端部分可以设置有选择性地成形的能量输送尖端元件。 能量输送尖端元件可以设置有次表面加热区域,其中所选择的植入材料将接收到的激光能量转换成热量,以施加到保持在套管的钩状开口端部分中的组织。 一旦所选择的组织被钩住,外科医生可以将尖端元件的加热或激光能量发射表面强制施加到待蒸发和切割的组织上。 烧灼表面可以设置在套针针的尖端元件上,或者替代套管的钩形部分。

    • A tip element is provided for attachment to a small hand-held elongate surgical tool, to enable a surgeon to utilize laser light energy conveyed along a single optical fiber and converted at a fine point of the tip element into a high temperature energy flux. Thus, instead of emitting laser light energy directly to a patient's tissues, the surgeon applies an extremely hot pointed tip very precisely to generate such high local temperatures as to substantially vaporize or gasify the tissue. An annulus is defined adjacent to and immediately around the heated portion of the tip element so that vapors and gaseous products generated during use of the device are immediately removed from the surgical site. An electrical connection may be provided to a distal portion of the tip element close to its heated point to enable a surgeon to contact a bleeding blood vessel thereby to effect cauterization by a cauterization current driven through the patient's body and controlled by a foot-operated switch.
    • 提供尖端元件用于附接到小型手持式细长手术工具,以使得外科医生能够利用沿着单根光纤传送的激光光能并将尖端元件的细点转换成高温能量通量。 因此,外科医生不是将激光光能量直接发射到患者的组织,而是非常精确地施加非常热的尖端,以产生如此高的局部温度,以使组织基本蒸发或气化。 围绕尖端元件的加热部分邻近并且紧邻周边限定环,使得在使用装置期间产生的蒸气和气体产物立即从外科手术部位移除。 可以将电连接件提供到尖端元件的靠近其加热点的远端部分,以使外科医生能够接触出血血管,从而通过驱动穿过患者身体的烧灼电流来实现烧灼,并由脚踏开关 。
