Description
Technical Field
The application relates to an operation auxiliary device, in particular to a brain midline positioning and scribing auxiliary device before craniocerebral operation.
Background
Careful planning and accurate positioning are required before craniocerebral surgery to ensure the accuracy of the surgery, where the midline of the brain is an important reference location. The midline of the brain is generally defined along the center of the patient's nasion to the occipital tuberosity. Deviations in the location of the delineated midline may be caused by physician experience or patient skull details (e.g., collapse or bulging of the skull-defective brain tissue).
CN 201668505U discloses a "positioning and scribing ruler for craniocerebral operations" in 12 th and 15 th 2010, which can reduce the dependency on the experience of doctors to some extent. Paragraph 0029 of the specification discloses: the position of the central line of the skull at the top (top midpoint) is determined by using a positioning scribing ruler for craniocerebral operation, and the sagittal line of the skull is scribed along three points of the nasal root midpoint, the top midpoint and the out-of-pillow tuberosity midpoint. The operation of using the line marking rule is relatively complex, requiring that the top midpoint be determined first, and then the top midpoint be used to determine the midline by taking the top midpoint to a three-point line. Moreover, the top midpoint is also defined as an opposite point, and if the top midpoint is defined as skewed, the position of the entire midline is offset from the actual midline position.
Disclosure of Invention
In view of the above, the present application aims to propose a pre-operative brain midline positioning and scribing aid that can help determine an accurate midline position using a relatively fixed medical anatomical location of the patient's cranium.
The auxiliary device for positioning and marking the pre-operation brain midline of the craniocerebral operation comprises a guide plate, a first auxiliary positioning arm and a second auxiliary positioning arm;
the guide plate is formed into a curved shape for placement along the cranial vertex of a subject, and a first end thereof includes a bifurcation for being retained in the nasal root position of the subject; the second end of which extends to the posterior cranial side of the subject;
the first auxiliary positioning arm is formed at the left side of the guide plate, is in an arc shape, and is provided with a spherical first positioning head at the lower end for supporting on a left earhole of a subject; the second auxiliary positioning arm is formed on the right side of the guide plate, is in an arc shape, and is provided with a spherical second positioning head at the lower end for supporting on a right ear hole of a subject;
positioning a guide plate at a midline position of the subject's cranium apex through the subject's left ear canal, right ear canal, and nasion position;
a strip-shaped scribing hole is formed along the length direction of the guide plate, so that a pen point of a scribing pen can extend into the scribing hole, and a scribing operation of scribing a central line is performed on the top of the cranium of the subject.
Preferably, the guide plates include a first guide plate and a second guide plate; the first guide plate and the second guide plate are rotatably connected together by a pin.
Preferably, the second end of the guide plate extends to an out-of-occipital tuberosity position of the subject.
The auxiliary device for positioning and scribing the pre-operation brain midline of the craniocerebral operation can position the midline through three medical anatomical points which are not on the same straight line, namely, the left earhole, the right earhole and the naso-root position, and help to accurately define the midline.

Detailed Description
The following. The auxiliary device for positioning and scribing the midline of the brain before craniocerebral operations is described in detail with reference to the accompanying drawings.
The auxiliary device for positioning and scribing the pre-operation brain midline of the craniocerebral operation comprises a guide plate, a first auxiliary positioning arm 3 and a second auxiliary positioning arm 4.
The guide plate is formed into a curved shape for placement along the cranial vertex of a subject, and includes a bifurcation 11 at a first end for being retained in the nasal root position of the subject; the second end of which extends to the posterior cranial side of the subject; preferably, the second end of the guide plate extends to an out-of-occipital tuberosity position of the subject.
The first auxiliary positioning arm 3 is formed at the left side of the guide plate, is formed in an arc shape, and is provided with a spherical first positioning head 31 at the lower end thereof for supporting on the left earhole of the subject; a second auxiliary positioning arm 4 is formed on the right side of the guide plate, the second auxiliary positioning arm being formed in an arc shape, and a spherical second positioning head 41 is mounted at its lower end for supporting on the right ear hole of the subject.
The guide plate is positioned at a midline position of the subject's cranium apex through the subject's left and right earholes, and the nasion position.
An elongated scribing hole 5 is formed along the length direction of the guide plate, into which a pen head of a scribing pen is inserted, and a scribing operation for scribing a center line is performed on the top of the cranium of the subject.
The guide plate can be integrally formed or can be formed by two parts.
In one embodiment, the guide plates comprise a first guide plate 1 and a second guide plate 2; the first guide plate 1 and the second guide plate 2 are rotatably connected together through pins; therefore, the auxiliary device for positioning and scribing the midline of the brain before craniocerebral operation can conveniently clamp the guide plate on the cranium of the subject no matter what position the subject is in.
When the scribing pen is used, the first end of the first guide plate of the guide plate is aligned with the nasal root position of a subject, the first positioning head of the first auxiliary positioning arm is supported on the left earhole of the subject, the second positioning head of the second auxiliary positioning arm is supported on the left earhole of the subject, the second guide plate of the guide plate is rotated to enable the second end of the second guide plate to be positioned on the rear side of the cranium of the subject, at this time, the guide plate is positioned at the center line position of the top of the cranium through the left earhole, the right earhole and the positioning of the nasal root position, and the scribing pen extends into the scribing hole to scribe a line, so that the center line with accurate position can be obtained.
