Cephalometric positioning photography chair for zygomatic arch, skull base, top-chin, and submandibular top

Abstract

The invention relates to a medical device. The invention discloses a zygomatic arch, skull base, top chin and submandibular top cephalometric positioning and shooting chair which comprises a skull positioning instrument, a supporting plate, a backrest, a seat and a seat supporting leg; the skull positioning instrument is fixed on the lower surface of the supporting plate by two chutes; the skull positioning instrument can slide relative to the supporting plate; the supporting plate is connected with the backrest by a rotating shaft; the backrest is connected with the seat by a regulating bolt; and the seat is connected with the seat supporting leg by a lifting regulating device. The zygomatic arch, skull base, top chin and submandibular top cephalometric positioning and shooting chair can be used for carrying out standard shooting of X-ray films on cranio maxillofacial region structures such as a zygomatic bone, upper and lower jawbones, a skull base, a nose and the like so as to carry out quantitative measurement; the zygomatic arch, skull base, top chin and submandibular top cephalometric positioning and shooting chair is convenient to use; the medical cost is saved; the accuracy and the objectivity of medical images are improved; and effects before and after the operative treatment can be accurately and objectively compared.

Description

technical field [0001] The invention relates to a medical device, in particular to a cephalometric positioning camera chair for zygomatic arch position, skull base position, chin position, and submandibular top position, that is, a chair for clinical medicine, plastic surgery, and craniomaxillofacial surgery. , Stomatology, imaging, X-ray diagnostics, head positioning camera chair for zygomatic arch position, skull base position, chin position, submandibular top position cephalometric measurement. Background technique [0002] The zygomatic arch position, skull base position, chin position, and submandibular position are the most difficult positions for radiographic X-ray photography. The current commonly used shooting positions of horizontal, vertical and sitting usually cause obvious discomfort to patients, and it is more difficult and painful for patients with craniofacial trauma and those who are recovering from craniomaxillofacial surgery in the near future , The shoot...

AI Technical Summary

Problems solved by technology

The current commonly used shooting positions of horizontal, vertical and sitting usually cause obvious discomfort to patients, and it is more difficult and painful for patients with craniofacial trauma and those who are recovering from craniomaxillofacial surgery in the near future , the shooting effect is also greatly reduced, which cannot meet the role of clinical assistance in diagnosis

[0003] In addition, when X-rays of these positions are taken in standing and sitting positions, due to the lack of necessary support, the patient cannot maintain the correct posture, and often tilts, shakes, etc., resulting in skewed and blurred X-rays taken in the end, which affects Diagnosis, difficult to use as a basis for surgical reference

[0004] At present, cephalometric measurement is limited to frontal and lateral photography, but for the cephalometric measurement of zygomatic arch, skull base, chin top, and submandibular top, it cannot be performed because there is no corresponding instrument to locate the head.
