Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to an ultrasonic osteotome handle. Background Art

[0002] An ultrasonic bone knife is a medical device for cutting or crushing bone tissue. It converts electrical energy into mechanical energy through a transducer installed in the handle, putting the blade in a high-frequency resonance mode. It uses the powerful mechanical acceleration of the blade to crush and cut the target bone tissue. It can be widely used in precise, high-risk orthopedic surgeries and is suitable for the clinical needs of multiple departments.

[0003] In order to save medical costs and resources and reduce the economic pressure on patients, the ultrasonic scalpel handle itself needs to be used repeatedly, which is easy to breed bacteria and is not conducive to the sterile environment of surgical operations. Therefore, the ultrasonic scalpel handle assembly needs to be strictly sterilized. At present, high-temperature steam is often used to sterilize the ultrasonic scalpel handle assembly. To achieve the sterilization of the ultrasonic scalpel handle assembly, the steam temperature needs to be controlled above 100°C, so it needs to be sterilized under high pressure and high temperature. Preferably, the steam temperature needs to be controlled above 120°C for sterilization of the handle assembly.

[0004] The commonly used sterilization equipment at present is a high-temperature steam cooker. When in use, the ultrasonic knife handle assembly is placed in a high-temperature steam cooker for sterilization. During the sterilization process, the ultrasonic knife handle assembly is continuously in a high-temperature, high-pressure environment. Usually, the pressure in the high-temperature steam cooker can be as high as 250kPa, and the sterilization is continued for more than 15 minutes. The ultrasonic knife handle in the prior art is connected to the external device through a cable and a connector on the cable to facilitate the control of the ultrasonic knife handle. The cable is often fixedly connected to the ultrasonic knife handle and cannot be disassembled. During the disinfection of the ultrasonic knife handle, high-temperature steam will enter the connector. After cooling, the steam will condense into liquid and corrode the connector, thereby affecting the connection between the connector and the external device, and then affecting the normal use of the ultrasonic bone knife. Summary of the invention

[0005] The purpose of the present invention is to provide an ultrasonic bone knife handle to solve the problem proposed in the above background technology that the cable is often fixedly connected to the ultrasonic knife handle and cannot be disassembled. During the disinfection of the ultrasonic knife handle, high-temperature steam will enter the connector. After cooling, the steam will condense into liquid and corrode the connector, thereby affecting the connection between the connector and the external device, and further affecting the normal use of the ultrasonic bone knife.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an ultrasonic bone knife handle, comprising a handle body and a connection seat fixed to one end of the handle body, a protective cover movably connected to a side of the handle body away from the connection seat, a germicidal lamp installed in the protective cover, a support column fixedly connected to the handle body is provided in the connection seat, and a wiring socket and a power cable are installed at both ends of the support column; A movable hole is provided at the top of the connecting seat, and a protective tube is movably connected in the movable hole at the top of the connecting seat, a pressing ring is fixed to the outer wall of the protective tube, and a mounting seat is fixed to the outer wall of one side of the protective tube, a connecting block is rotatably connected to the mounting seat via a rotating shaft, and a sealing cover for sealing the protective tube is fixed on the end face of the connecting block.

The protective tube is pushed downward by pressing the ring, and the wiring socket pushes the sealing block and the sealing cover to rotate the sealing cover. The wiring socket extends to the top of the protective tube, which is convenient for connecting the external plug to the wiring socket. At the same time, the compression spring supports the guide plate, so that the positioning pin is inserted into the positioning groove of the guide plate, which can fix the position of the protective tube to avoid accidental movement of the protective tube during the operation of the handle body, and is more stable to use. The ultrasonic bone knife handle is not only convenient for disinfecting the handle body, but also can prevent external high-pressure steam from entering the handle body during disinfection. In addition, the external cable is detachably connected to the handle body through the wiring socket, which is convenient for disinfection and carrying of the handle body.
