This invention belongs to the field of surgical instrument technology and discloses a disposable sterile specimen retrieval bag with spill prevention, comprising a cannula, a push rod, and a specimen bag. The push rod is slidably connected inside the cannula, and the specimen bag is connected to one end of the push rod. The specimen bag includes a support strap with several ratchet teeth on one side. One end of the support strap is connected to a buckle, and the buckle has protrusions that match the ratchet teeth. The other end of the support strap passes through the buckle. The support strap and the buckle form an elastic annular support ring. A hollow sleeve is fitted onto the annular support ring, with one end connected to the end of the support strap and the other end connected to the buckle. The hollow sleeve is connected to the retrieval bag body. This invention solves the technical problems of existing specimen bags having limited options for aperture specifications, being easily damaged, and having a semi-closed opening that hinders the smooth placement of specimens.

The application relates to the field of medical devices, in particular to a polyethylene acetabular prosthesis. The polyethylene acetabular prosthesis comprises an acetabular body capable of replacing a hip bone lesion resection site and an acetabular liner; the acetabular body is provided with an ilium connecting part, a pubis connecting part and a liner connecting part; the ilium connecting part is provided with an ilium screw hole for fixing the acetabular body on the hip bone, and the pubis connecting part is provided with a pubis screw hole for fixing the acetabular body on the hip bone; the liner connecting part is used for fixing the acetabular liner; the inner wall of the acetabular liner is matched with the acetabular structure and is used for being matched with the femoral head, and the outer wall of the acetabular liner is provided with a plurality of clamping pieces used for being connected with the liner connecting part; and the liner connecting part is matched with the outer wall of the acetabular liner. The application can realize accurate replacement of the resected acetabulum of a patient while retaining the acetabular bone and the femoral head of the patient, thereby shortening the operation time and reducing the operation risk.

The application discloses an in-situ synthesis method of a silicon-carbon nanocomposite material for a lithium ion battery negative electrode material, and belongs to the field of lithium ion batteries. A segmented feeding mode is adopted, and the temperature zone of a silicon nanowire forming process and a carbon-silicon composite process is controlled, so that the carbon-silicon reaction speed is inhibited, and the formation of silicon carbide is effectively avoided. First, a silicon source precursor is axially delivered into an inductive thermal plasma high-temperature zone, silicon vapor is obtained under the action of high temperature, and the silicon vapor is cooled during leaving the high-temperature zone, so that silicon nanowires are obtained through nucleation and growth. In the tail of the inductive thermal plasma arc, acetylene, methane and other gas carbon sources are added, and carbon formed through pyrolysis is nucleated on the silicon surface in a heterogeneous phase, so that a silicon-carbon composite material is obtained. The problems of uneven carbon layer coating and easy oxidation of nanomaterials are solved.
