    摘要： The present invention relates to a head immobilization system for immobilizing a patient's head in a supine position of the patient, the system comprising: - a support rail structure (1) adapted to be coupled to a patient rest (2) and extending at least on both lateral sides of the patient's head, - a mask frame (3) adapted to be coupled to at least one deformable upper mask sheet (4), wherein the mask frame (3) is releasably connected to the support rail structure (1) via a first interface section (5) and a second interface section (6), with at least two pins (7) protruding from the first interface section (5) in a first direction (U), and at least two pin-receptions (8) provided at the second interface section (6), wherein each one of the pin-receptions (8) receives one of the pins (7), and - a catch-mechanism (9) for each pin-reception (8) and each corresponding pin (7), which allows the pin (7) to be pushed further into the pin-reception (8) in the first direction (U), but which interlocks in case of an attempted withdrawal of the pin (7) from the pin-reception (8) in a second, opposite direction (D).

    摘要： A support unlocking apparatus (100), comprising a head holder adaptation mechanism (110) and a clamping mechanism (120); the head holder adaptation mechanism (110) comprises an adaptation assembly (112) connected to a head holder mechanism (510) and a mounting plate (111) on which the adaptation assembly (112) is mounted; the clamping mechanism (120) is arranged on a head holder fixing mechanism (200) and clamps the mounting plate (111), the clamping mechanism (120) has an unlocking state and a locking state; when a drag force applied to the head holder adaptation mechanism (110) exceeds a threshold of the clamping mechanism (120), the clamping mechanism (120) is in the unlocking state, and the mounting plate (111) can move relative to the clamping mechanism (120), and when the clamping mechanism (120) is in the locking state, the mounting plate (111) is fixed in the clamping mechanism (120). When an accident occurs, the clamping mechanism (120) automatically unlocks the mounting plate (111) under the effect of a drag force of the head holder mechanism (510), the position of the head holder mechanism (510) is no longer fixed, and the head holder mechanism can sink along with a surgical bed system (500), preventing a patient (600) from being harmed, and achieving the effect of safety protection. Further disclosed are a joint locking mechanism (140), a head holder fixing mechanism (200) and a surgery assisting robot system.
