摘要： An electrocautery probe includes a single probe arm and an electrode. The electrode includes one end attached to the probe arm and a free end. According to one embodiment of the invention, the electrode is a wedge, preferably having a substantially triangular cross section. According to another embodiment of the invention, the free end of the electrode rises higher than the attached end of the electrode. The free end of the electrode may be planar, pointed, or rounded. Where the free end of the electrode is planar, it may be inclined in either the proximal or distal direction. According to yet another embodiment of the invention, the electrode is a roller barrel. The electrocautery probe has several advantages over two armed electrocautery probes. First, the electrocautery probe has only one arm obscuring the physician's view through the lens of the resectoscope. Second, the free end of the electrode can be used for sculpting tissue and for resecting tissue in narrow areas. Third, the free end of the electrode can be used for spot coagulation. Fourth, the free end is capable of larger resections than possible with a two-armed electrocautery probe. In addition, the electrocautery probe fits into a standard resectoscope without modification to the resectoscope device.

摘要： A snap-fit collar for coupling the end of a flexible coil to a part of an endoscopic instrument is a substantially cylindrical member having a first end portion with a stop flange, a resilient tapered locking flange spaced apart from the stop flange defining a waist or groove between the stop flange and the locking flange, and second end portion having a pair of cantilevered substantially semi-cylindrical legs. The first end portion is preferably frustroconical and flares diametrically outward to form the stop flange which has a first diameter. The waist or groove has a second diameter which is smaller than the first diameter. The tapered locking flange is also preferably frustroconical and tapers diametrically inward from a third diameter which is larger than the second diameter. Each of the legs is inclined diametrically outward and includes a plurality of coil engaging ribs on its inner surface. The outer surface of each leg is preferably provided with a longitudinal key and the free end of each leg is preferably tapered radially inward. The collar has a throughbore which extends through the first end portion to the space between the legs. An endoscopic instrument actuator and a clevis for use with the snap-fit collar each include a throughbore having a step and a pair of diametrically opposed keyways which extend into at least a portion of the throughbore wall.

摘要： An endosurgical cutting instrument includes a hollow tube having a distal end with a radial slot and an interior deflection surface, a push rod extending through the tube and having a proximally directed sickle blade coupled to its distal end, and a manual actuator coupled to the proximal ends of the tube and the push rod for imparting relative axial movement to the tube and push rod. The sickle blade is a curved member having a sharp concave edge and a dull convex edge and is coupled to the distal end of the push rod with its sharp concave edge facing the push rod. The blade is dimensioned such that it may be substantially completely contained within the tube. The push rod is oriented so that its distal end is free to move in a radial direction as it moves axially. Movement of the push rod against the deflection surface urges the push rod in a radial direction thereby causing the sickle blade to exit the tube through the radial slot. As the sickle blade is moved out of the tube, there is no cutting action since it is the dull convex edge of the blade which faces the tissue adjacent to the tube. Once the blade is deployed outside the tube, cutting is effected by capturing tissue in the space between the concave cutting edge of the blade and the exterior of the tube.

摘要翻译： 内窥镜切割仪器包括具有远端的中空管，其具有径向槽和内部偏转表面，推杆延伸穿过管并且具有联接到其远端的近端指向的镰刀刀片，以及联接到近端的手动致动器 管的端部和推杆用于相对于管和推杆的相对轴向运动。 镰刃是具有锐利的凹边缘和钝的凸边缘的弯曲构件，并且其突出的边缘朝向推杆而联接到推杆的远端。 叶片的尺寸使得其可以基本上完​​全包含在管内。 推杆被定向成使得其远端在轴向移动时沿径向方向自由移动。 推杆抵靠偏转表面的移动迫使推杆沿径向移动，从而使镰刀片通过径向狭槽离开管。 当镰刀被移出管时，不存在切割作用，因为它是面向邻近管的组织的刀片的钝的凸边。 一旦叶片被部署在管外部，通过在叶片的凹形切割边缘和管子的外部之间的空间中捕获组织来实现切割。

摘要： An electrocautery probe with a variable morphology electrode includes a coil electrode extending through the distal end of a probe, an adjustment mechanism operable from a proximal end of the probe for changing the morphology of the coil electrode, and a connection for receiving a current for application through the electrode. The morphology of the electrode can be changed by adjusting the length of electrode which extends from the probe. In a preferred embodiment, the morphology of the electrode can also be changed through the use of slider having a shaped head which extends from the distal end of the probe and presses against the electrode. The shaped head of the slider can have a variety of shapes and when the shaped head of the slider urges against the electrode, the electrode is formed to the same shape as that of the distal end of the slider head. Also provided are mechanisms for adjusting and maintaining the position of the slider and shaped head with respect to the electrode.

摘要： Electrodes for electrocautery probes for use with a resectoscope include full loop electrodes wherein the full loop has a working surface which extends below the axis of the cautery probe and a working surface which extends above the axis of the cautery probe, composite full loop electrodes wherein the upper working surface and the lower working surface have different morphology, combined full loop and roller electrodes wherein one of the upper or lower portions of the loop serves as the axle for a roller electrode, and bifurcated full loop electrodes wherein the upper working surface and the lower working surface can be independently energized. The electrodes according to the invention permit resection of upper and lower prostate lobes without requiring inversion of the resectoscope, thereby shortening the time for the procedure. In addition, the full loop electrodes with different upper and lower morphology provide additional treatment options while also reducing the time for the procedure. Furthermore, the bifurcated full loop electrodes provide the ability to use different power settings for the upper and lower working surfaces.
