A temporomandibular joint distractor and a temporomandibular joint pressing device (20). The temporomandibular joint pressing device (20) is for enlarging the temporomandibular joint space and comprises: an installation base (50); at least one pressing structure (21) and at least one adjustment structure (22) installed on the installation base (50). The pressing structure (21) comprises a pressing part (211) and a connecting part (212). The pressing part (211) is connected to the adjustment structure (22) via the connecting part (212), such that, under the action of the adjustment structure (22), the connecting part (212) drives the pressing part (211) to move to a temporomandibular joint of a patient and to press down on the temporomandibular joint. The temporomandibular joint pressing device (20) adjusts, via the adjustment structure (22), the position of the pressing structure (21) relative to the temporomandibular joint, so as to enable the pressing structure (21) to press down on the temporomandibular joint of the patient so as to stretch the temporomandibular joint space to a certain degree, allowing the patient to open their mouth to a larger angle and thus achieving greater convenience in the use of the temporomandibular joint distractor.La présente invention concerne un distracteur d'articulation temporo-mandibulaire et un dispositif de pression d'articulation temporo-mandibulaire (20). Le dispositif de pression d'articulation temporo-mandibulaire (20) est destiné à agrandir un espace d'articulation temporo-mandibulaire et comprend : une base d'installation (50); au moins une structure de pression (21) et au moins une structure de réglage (22) installée sur la base d'installation (50). La structure de pression (21) comprend une partie de pression (211) et une partie de liaison (212). La partie de pression (211) est reliée à la structure de réglage (22) par l'intermédiaire de la partie de liaison (212), de telle sorte que, sous l'action de la structure de ré
