This invention discloses an anti-fog and heat-insulating puncture device for thoracoscopic surgery, belonging to the field of medical device technology. Its key technical features include: an outer sheath, with a puncture assembly on its inner wall, the puncture assembly including a puncture needle core that slides through the inner wall of the outer sheath, a needle core handle fixedly connected to the upper end of the puncture needle core, a needle tip fixedly connected to the lower end of the puncture needle core, an outer sheath seat fixedly connected to the upper outer wall of the outer sheath, a fixing handle fixedly connected to the outer wall of the outer sheath seat, and a sealing assembly on the outer wall of the outer sheath seat. This invention achieves heat insulation through a double-layer structure formed by the outer and inner sheaths; gas circulation is formed through the cooperation of the air inlet and outlet holes, effectively expelling fog from the inner wall of the inner sheath and ensuring a clear surgical field; the sealing valve and sealing sleeve achieve internal sealing of the outer sheath to prevent gas leakage; the sealing ring is precisely positioned by positioning pins and positioning holes, and the sealing cap is stably installed by locking blocks and protruding pins, providing double sealing to prevent gas leakage and impurity entry, reducing the risk of infection.

The utility model discloses a bend pipe with anti -deformation structure, including elbow main part and set up in the both ends of elbow main part for with the connecting portion of pipeline, the inboard wall of arc outside elbow main part inlays the rib plate, and the outside vertical fixed of rib plate has the connecting piece, and the one end of connecting piece extends to outside and is fixed with two fixed rings through elbow main part, and the elastic gasket is clamped between two fixed rings. The utility model discloses through setting up the aluminum alloy rib plate of higher structural strength to improve elbow main part fluid impact resistance, so that elbow main part is not easy to damage, prolongs the life, has the effect of supporting elbow main body simultaneously, improves the overall structural strength of elbow main body, makes it not easy to take place deformation, and installs the expansion bolt on the wall of pipeline system installation with the fixed ring corresponding position, and the expansion bolt provides the support force to elbow main body through the connecting piece, to resist the fluid impact pressure of long -term, thereby prevent elbow pipe deformation avoids the influence sealing effect.

This invention provides an automated packaging machine for finished wire products, relating to the field of wire packaging technology. It includes: an outer machine with an open top section; an inner lining frame fixedly installed inside the opening; a lower support fixedly installed on the front side of the inner lining frame; a lower support cylinder fixedly installed in the middle of the lower support; and a lower support plate fixedly installed at the telescopic end of the lower support cylinder; a lifting control frame fixedly installed on the front top section of the outer machine. This invention is adaptable to the overall packaging needs of various specifications of wire. Through the coordinated operation of the rolled plastic packaging film, the double heat-sealing strip of the heat sealer, and the cutting blade, the packaging film is precisely cut, and the first basic heat seal is completed simultaneously. This provides a complete packaging function for the wire throughout the entire process, ensuring a tight fit between the packaging film and the wire roller, and achieving continuous supply of packaging film without frequent individual packaging, facilitating subsequent sealing processes, and adapting to the needs of large-scale continuous operation.

The utility model provides a kind of rotary equipment discharge pipe sealing device, moving ring includes the dynamic connection ring and dynamic sealing ring connected as a whole, dynamic connection ring is fixedly sleeved on discharge pipe;Static ring includes static connection ring, first static sealing ring and second static sealing ring, static connection ring is fixedly sleeved on the discharge pipe, the recess of first static sealing ring and second static sealing ring is covered on the cross structure of dynamic sealing ring, forms four overall annular cavities, four cavities are all tightly filled with sealing packing, first static sealing ring and second static sealing ring are connected and fixed by connecting piece, so that first static sealing ring and second static sealing ring will sealing packing be pressed on dynamic sealing ring. Contact sealing is carried out to discharge pipe and discharge pipe by four-corner distribution sealing packing, sealing effect is good, structure is simple, convenient to assemble and disassemble, service life is long, and axial movement resistance and radial deflection resistance effect are good.
