Unlocking assembly and human body fixing device

Abstract

The invention, which relates to the technical field of medical instruments, provides an unlocking assembly and a human body fixing device. The device comprises a fixed plate, a locking body and a flexible member. A fixed hole is formed in the fixed plate; and the locking body is movably mounted in the fixed hole. The flexible member is connected with the locking body and is configured to drive thelocking body to move in a direction extending out of the fixed hole. Since the locking body is telescopically mounted in the fixed hole in the fixed plate and the flexible member can drive the locking body to move towards the direction extending out of the fixed hole, the locking between the locking body and the fixed hole can be released only by remotely controlling the flexible member, so thattechnical problems that in the prior art, a fixing device is numerous in unlocking steps and long in unlocking time and can only be unlocked at a close distance are solved. Therefore, the fixing device can be easily unlocked in the radiotherapy process and the time needed for unlocking is shortened.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an unlocking assembly and a human body fixing device. Background technique [0002] Radiation therapy for tumors is a local treatment method that uses radiation to treat tumors. Radiation includes α, β, γ rays produced by radioactive isotopes and x-rays, electron beams, proton beams and other particle beams produced by various x-ray therapy machines or accelerators. About 70% of cancer patients need radiotherapy in the course of cancer treatment, and about 40% of cancers can be cured with radiotherapy. [0003] During the radiotherapy process, it is necessary to use a fixing device to fix the human body between the low-temperature thermoplastic membrane and the base plate. The fixing device generally uses a low-temperature thermoplastic membrane and a special base plate to ensure that the patient is in a fixed position during the entire radiotherapy process. It is c...

Problems solved by technology

[0004] However, once the fixing device on the market is fixed and locked, it can only be unlocked close to the fixing device. If the patient has an emergency and cannot unlock the fixing device in time, the patient will still be trapped in the low-temperature thermoplastic film and the fixing base plate, and must not be released. Get up, and doctors are usually outside the treatment room. After discovering the problem, they have to run into the treatment room to get close to the fixing device and unlock multiple fixing devices, often missing the best time for the patient to rescue.
