Abstract

The invention discloses a spreader for oral and maxillofacial surgery, which includes a movable frame, a support frame and an adjustment box. The front of the adjustment box is provided with a scale line, and the inside of the adjustment box is movably installed with a two-way threaded screw rod. , the first thread kit is movably installed on the two-way threaded screw rod, the top of the limit seat is fixedly installed with a movable frame, the outer side of the movable frame is movably installed with a support frame, and the back of the movable frame is passed through a threaded rod An upper support base is movably installed, and a lower support base is movably installed on the bottom of the upper support base. In the present invention, a two-way threaded screw rod is movably installed inside the adjustment box, and the movable frame is driven to move relatively by rotating the two-way threaded screw rod, and the pointer can be used to cooperate with the scale line, so that the spacing of the opening can be grasped more conveniently. The lower support seat is installed in the activity, which can make the patient occlude on the upper support seat and the lower support seat, and it is not easy to fall off, which is convenient and quick.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a retractor for oral and maxillofacial surgery. Background technique [0002] Oral and maxillofacial surgery is mainly based on surgical treatment. It studies oral organs, facial soft tissues, maxillofacial bones, temporomandibular joints, salivary glands, and some related diseases in the neck. If a disease occurs in the oral and maxillofacial region, if it is not treated in time and correctly , the consequences are more serious, and usually need to use the spreader to open the patient's oral cavity when treating oral and maxillofacial surgery, so that the medical staff can perform the operation conveniently. [0003] The existing defects of the retractor for oral and maxillofacial surgery are: [0004] 1. It is inconvenient to grasp the spacing of the mouth opening, which may cause secondary damage to the patient due to excessive opening spacing, which reduces the conve...
