The utility model discloses a six -sided top press top hammer crack detection instrument relates to crack detection technical field. The utility model discloses a handle, the surface of handle is provided with recess, the surface of recess is provided with mounting groove, the inner chamber magnetic of mounting groove has toughened glass, one end of handle is provided with threaded hole, the inner chamber threaded connection of threaded hole has the core cylinder. The utility model solves the problem that the existing detection instrument wears fast, and the problem of frequent maintenance, and the cooperation structure of the core needle and the core cylinder is used to the tool, the core needle adopts the fine diameter metal wire design, compared with the traditional 3 5mm diameter's scratch hammer hook, reduces the contact area with the top hammer surface, reduces the wear rate, and the tip does not need to be polished every day, and the length of the core needle is greater than the core cylinder, when the tip wears, can continue to use through the adjustment core needle length of exposure, greatly prolongs the replacement cycle, reduces the maintenance cost and the operation interruption time, and improves the detection efficiency.

The dust removal mechanism comprises a dust removal box, an air inlet channel, an operation cavity and a dust collection cavity are formed in the dust removal box, a cutting knife stretches into the operation cavity through the side face and is exposed out of a bottom opening, and the air inlet channel is connected with an air pipe and communicates with the operation cavity; the rear end of the operation cavity is connected with the dust collecting cavity, and a dust discharging opening is formed in one side of the dust collecting cavity. After the high-pressure air pipe is connected to the air inlet channel, high-pressure and high-speed air flow can be blown into the working cavity where the cutting knife is located, chippings generated by cutting can be directly blown into the dust collecting cavity to be collected, and the chippings can be discharged in time through the dust discharging opening in the side face and are prevented from falling onto a glass plate or glass plates on the front side and the rear side, and surface cleanliness is guaranteed; and subsequent treatment is facilitated.

The present invention provides an intraoperative coronary guide wire fixing device, belonging to the technical field of medical devices. The intraoperative coronary guide wire fixing device includes a U-shaped splint screwed to one side of the operating table by screws. One side of the U-shaped splint is fixedly connected with an L-shaped support plate. One end outer wall of the L-shaped support plate is fixedly connected with a C-shaped support buckle. A catheter is clamped on the inner wall of the C-shaped support buckle. A guide wire is slidably connected to the inner wall of the catheter; a fixing component, which is used to fix the guide wire during the operation, and the fixing component is respectively connected with the L-shaped support plate. By setting the fixing component, the present invention can not only provide a clamping effect for the guide wire during the process of the doctor pulling the guide wire, which is beneficial to accurately guiding the guide wire to the blood vessel position to be treated, but also fix the guide wire after guiding the guide wire to the target blood vessel, avoiding the guide wire slipping out of the target blood vessel and affecting the subsequent operation of the surgery.

The utility model discloses blood cleaning equipment which comprises a machine body, a main recycling tank, an auxiliary recycling tank, a cleaning liquid structure, an attractant recycling structure and a waste liquid recycling structure, and a purification structure is arranged in the machine body. One end of the main recovery tank is provided with a first aspirator, and the other end is communicated with the purification structure; one end of the auxiliary recovery tank is provided with a second aspirator, and the other end is communicated with the main recovery tank; the washing liquid structure and the attractant recovery structure are both communicated with the purification structure; the waste liquid recovery structure is communicated with the purification structure. By arranging the main recovery tank and the auxiliary recovery tank, an aspirator can be sucked into the auxiliary recovery tank at the beginning of an operation, when it is confirmed that the aspirator needs to be purified, the aspirator in the main pipe is completely purified and then input into a human body, otherwise, the aspirator is directly input back into the human body, and therefore different aspirators can be managed separately; when the main recycling tank is independently used, the amount of sucked objects is large, and the main recycling tank cannot contain the sucked objects, the sucked objects can be input into the auxiliary recycling tank to be temporarily stored.
