摘要： An air introduction system for a medical needle assembly is provided and includes a flexible bladder, and a male luer assembly with an air valve which is biased to allow air to enter the air introduction system but not to exit. The air introduction system is coupled to a needle assembly which is to be introduced into the epidural space. As the needle traverses the tissue layers overlying the epidural space, and the practitioner applies pressure to the bladder, the practitioner experiences resistance to the forcing of air through the needle assembly. If air is lost from the bladder, the bladder may be refilled by releasing the pressure on it and allowing outside air to enter via the air valve. Once the epidural space is penetrated, air is quickly forced from the bladder through the needle assembly and the practitioner can feel a sudden drop in pressure. To aid in detection, the air introduction system is provided with an air activated sound device situated so as to be exposed to the air flow pushed out of the bladder. With the sound device, an audible warning is provided as the air rushes from the bladder through the needle assembly and into the epidural space.

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 endoscopic tool for dispensing units of hemostatic agent broadly comprises a hollow tube which holds a plurality of individual units of the hemostatic agent, a valve at the distal end of the hollow tube which permits the hemostatic agent to pass therethrough but prevents foreign matter from contacting the hemostatic agent while in the tube, a plunger which extends into the hollow tube and contacts a proximal unit of the hemostatic agent, and a mechanism for moving the plunger distally in incremental movements to cause, upon each incremental movement, an individual unit of the hemostatic agent to be pushed through the valve. Typically, the mechanism for moving the plunger and the proximal end of the hollow tube are held in a handle. One mechanism for moving the plunger utilizes a portion of the plunger as a ratchet by forming a plurality of conical elements thereon, and utilizes a switch in the handle which has a V-spring coupled thereto as a pawl for advancing the conical elements. A second mechanism utilizes a regularly shaped notched cutout in the handle as the ratchet, and a vertical protrusion on the plunger which extends through the cutout as an engagement element. The notched cutout provides resilient stops, and the protrusion is shaped to allow it to be forced in a forward direction through each resilient stop and then to sit in another notch.

摘要： An algorithm for ordering selects for a plurality of channels to be multiplexed into a frame is provided. The channel select position counter for each of the channels to be multiplexed are initialized. The first and succeeding channel selects are chosen based on the lowest price (highest cost) ready channel, with the price of a channel being equal to the value of the channel select position counter divided by the number of selects for that channel in the frame, and the readiness of the channel being indicated either by an indicator, or by the relative value of the position counter to the initial value of the position counter. Where channel prices are equal, the select is chosen on the secondary basis of channel rate, with the highest rate channel contributing first. After a select is made, the position counter of the selected channel is increased by the total number of selects in the frame. Then, the position counters of all of the channels, including the selected channel are decremented by a value corresponding to the number of selects for that channel in the frame. After such updating, another selection for the frame may be made based on the lowest priced ready channel. The provided algorithm guarantees that no channel will ever have an excursion of more than one bit available for placement in the frame.

摘要翻译： 提供了一种用于排序的多路复用通道的选择算法。 要复用的每个通道的通道选择位置计数器被初始化。 基于最低价格（最高成本）就绪通道选择第一和后续通道选择，其中通道的价格等于通道选择位置计数器的值除以该通道中该通道的选择次数， 并且通过指示符指示通道的准备状态，或通过位置计数器与位置计数器的初始值的相对值来指示。 在频道价格相等的情况下，选择是以频道费率的次要方式选择的，频率费率最高的是第一位。 在进行选择之后，所选频道的位置计数器增加帧中选择的总数。 然后，包括所选择的信道的所有信道的位置计数器减少与帧中该信道的选择次数对应的值。 在这种更新之后，可以基于最低价准备好的信道进行该帧的另一选择。 所提供的算法保证没有通道将不会有超过一位可用于放置在帧中的偏移。
