摘要： A termination for silicon superjunction VDMOSFET comprises heavily doped N-type silicon substrate which also works as drain region; drain metal is disposed on the back surface of the heavily doped N-type silicon substrate; an N-type silicon epitaxial layer is disposed on the heavily doped N-type silicon substrate; P-type silicon columns and N-type silicon columns are formed in the N-type silicon epitaxial layer, alternately arranged; a continuous silicon oxide layer is disposed on a part of silicon surface in the termination; structures that block the drift of mobile ions (several discontinuous silicon oxide layers arranged at intervals) are disposed on the other part of silicon surface in the termination. The structures that block the drift of mobile ions disposed in the termination region are able to effectively prevent movement of the mobile ions and improve the capability of the power device against the contamination induced by the mobile ions.

摘要： A needle guide holder, which is used for a fixing medical puncture needle and a ultrasonic probe, comprises a holder body (1a, 1b) and a fixing device (2a, 2b) used in cooperation with the holder body (1a, 1b). The fixing device (2a, 2b) is mounted onto the holder body (1a, 1b) and provided with a weakening portion (23a, 23b). The needle guide holder is designed to be disposable, thereby avoiding the possibility of cross-infection caused by using the same needle guide holder on different patients. The needle guide holder can be used on one and same patient to perform a number of treatments just through the replacement of a sliding frame and without replacing the fixing device and a fixing frame. In a treatment process, the puncture needle is left in the body for a subsequent treatment, while the needle guide holder and the ultrasonic probe can be removed from the human body.

摘要： Disclosed are a puncture guider (02, 2) and a puncture guiding system, wherein a puncture channel (80) automatically adapted to the diameter of a puncture needle (03) can be realized in the puncture guider (02, 2). The puncture guider (02, 2) is used for connecting to a puncture support, and the puncture guider (02, 2) comprises a depth block (21) and a push plate (22), wherein the depth block (21) comprises: a connection structure for being connected to the puncture support, and a first guiding wall (211) and a second guiding wall (212), which are connected to each other and form an included angle; and the push plate (22) comprises: a needle groove plate (222), and an adaptive component. A first end face (2221) of the needle groove plate (222), and the first guiding wall (211) and the second guiding wall (212) enclose a puncture channel (80), and under the action of the adaptive component, a displacement can occur between the first end face (2221) of the needle groove plate (222) and the first guiding wall (211) and second guiding wall (212), so that the puncture channel (80) can change automatically according to the specification of the puncture needle (03), thereby automatically adapting to puncture needles (03) with different needle diameter specifications. The puncture guiding system comprises a puncture support and a puncture guider (02, 2).

摘要： A probe sleeve (1), a pipe socket (2), a pipe socket assembly, and a method for wrapping the probe sleeve (1) around the pipe socket (2), wherein the probe sleeve (1) comprises a large diameter section (11) and a small diameter section (12); the free end of the large diameter section (11) is an open end (111), and the free end of the small diameter section (12) is a closed end (121). The probe sleeve (1), which is an intracavitary probe sleeve/transesophageal probe sleeve, can be used with the pipe socket (2) and as a surrogate of a condom, and can achieve an aseptic operation in an operative process. The method for wrapping the probe sleeve (1) around the pipe socket (2), which wraps the probe sleeve (1) around the pipe socket (2), is used for an ultrasonic B-ultrasound operation, and can meet the requirements of an aseptic operation.

摘要： A double-sided needle groove, a frame body and a puncture frame, wherein the double-sided needle groove has an axisymmetric outer contour, and is provided at one side with at least one needle slot a (1) and at the other side with at least one needle slot b (2); and the needle slot b (2) is fan-shaped. The double-sided needle groove is provided with one or more needle slots a (1) having a fixed needle insertion angle and a needle slot b (2) having an adjustable needle insertion angle, and the needle slot a (1) and the needle slot b (2) respectively correspond to the diameters of puncture needles and may be designed to meet multiple width specifications. During the performance of a B-ultrasound puncture operation, based on operation requirements of a surgeon for a fixed or adjustable angle, there is only a need to switch front and back sides of the double-sided needle groove, thus avoiding the need for an additional puncture frame, and switch the needle slots according to the diameters of the puncture needles. As can be seen, the double-sided needle groove can be applied to various types of B-ultrasound puncture operations and can effectively reduce the number of accessories in the puncture operations, thereby providing fast installation, saving resources and reducing costs.

摘要： A needle groove body, a puncture frame body and a puncture frame, wherein the needle groove body is a hollow cylindrical structure, and comprises a first baffle, a first fixing plate, a limiting plate, and a second fixing plate which are connected in sequence. The needle groove body has multiple specifications and can adapt to puncture needles of different specifications in puncture operations; a u-shaped needle groove can be formed between the first baffle of the needle groove body and a second baffle as well as an inclined mounting plate of the puncture frame body so as to accommodate free movement of a puncture needle in the u-shaped needle groove; and the u-shaped needle groove, which is semi-open, can implement a function of needle-frame separation (separation of the puncture needle from the puncture frame) in puncture operations.
