This utility model relates to the field of osteotomy devices, and discloses a femoral neck osteotomy device for hip replacement, including a fixing sleeve. A support frame is fixedly connected to the outer wall of the fixing sleeve near the front end. A rotating sleeve is hinged to the inner wall of the support frame near the rear end. A limiting component is provided on the inner wall of the support frame. The limiting component includes a stop block, which is fixedly connected to the inner wall of the support frame. A serrated block is provided on the outer side of the rotating sleeve near the front end. The rear surface of the stop block penetrates and is slidably connected to the limiting block. The limiting block and the stop block are elastically connected by a limiting spring. Multiple sets of fixing sleeves and rotating sleeves are provided. In this utility model, by setting the limiting component, the entire device can be fixed at the predetermined osteotomy position using the fixing sleeve and rotating sleeve during cutting, and then cutting can be performed along the cutting groove. This guides the cutting and ensures the flatness of the cut surface.

The utility model relates to medical instrument technical field discloses a kind of quick assembly and disassembly mechanism of extracorporeal counterpulsation device capsule, including air pipe, gas shunt connecting seat and several capsules, capsule is arranged above counterpulsation bed, every capsule is equipped with one connection male head, the both ends of air pipe are equipped with connection female head, corresponding several second connection male head are provided on gas shunt connecting seat, one connection male head and the connection female head of air pipe one end are connected with joint, second connection male head and the connection female head of air pipe other end are connected with joint.The technical scheme of the utility model can solve the problem of the existing technology that thread connection mode leads to dismounting operation cumbersome, maintenance efficiency is low and long-term use is easy to cause gas leakage due to thread wear.

This utility model discloses a roller pressure rod structure for a cat litter box, including symmetrically arranged shaft grooves and a flip-up pressure rod, a locking assembly at the free end of the pressure rod, and a rotating support assembly. The shaft groove is a semi-circular groove with an open top. The pressure rod is hinged to the edge of the shaft groove opening via a shaft seat. When closed, the pressure rod and shaft groove fit together to form a circular ring that embraces the rotating shaft. When open, it allows the rotating shaft of the litter box roller to disengage. The locking assembly achieves stable locking and quick manual unlocking of the pressure rod through a hook, a seat, and a return spring. The rotating support assembly consists of the shaft groove, a roller groove on the inner side of the pressure rod, and a roller, converting sliding friction into rolling friction, reducing resistance and wear. The purpose of this utility model is to provide a solution that solves the problems of slow disassembly, difficult cleaning, and easy wear of traditional screw fixing methods, as well as the unreliable locking of existing snap-fit ​​structures, thereby achieving "one-click opening and closing" for quick disassembly, improving cleaning efficiency and user experience, and significantly enhancing the user experience.

The application relates to the technical field of seat belt buckles, in particular to a novel seat belt buckle which comprises a seat belt, the front surface of the seat belt is fixedly connected with a connecting belt, the bottom of the connecting belt is fixedly connected with a binding belt one, the bottom of the connecting belt is fixedly connected with a binding belt two on the side away from the binding belt one, the front surface of the seat belt is provided with a special-shaped key, the back surface of the special-shaped key is provided with a special-shaped clamping groove, the inner wall of the special-shaped clamping groove is in contact with the outer wall of an anti-misoperation plate, the special-shaped key, the anti-misoperation plate and the special-shaped clamping groove are arranged, the special-shaped key and the anti-misoperation plate form a unique matching relationship, the special-shaped key is specially kept by a staff, only when the staff inserts the matching special-shaped key into the anti-misoperation plate and makes the special-shaped clamping groove accurately adhere to the anti-misoperation plate, the unlocking mechanism can be triggered, accidents caused by the misoperation or improper operation of non-staff are avoided, and the safety protection performance of the buckle is obviously improved.
