Description

TFCT craniocerebral positioning ruler

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a TFCT craniocerebral location ruler.

Background

Before craniocerebral operation, the positioning of intracranial lesions is crucial, and the current craniocerebral positioning puncture method mainly comprises the following steps: 1. CT film simple three-dimensional positioning method: the method has the advantages that the positioning experience of doctors for many years is poor in accuracy and high in error rate for most young doctors. 2. Frame type brain stereotaxic apparatus technique: the positioning precision is high (1 mm level), and the positioning device is commonly used for operations such as intracerebral electrode implantation and the like which need accurate positioning, and is also used for puncture operations of cerebral hemorrhage in China, but the operation process is complicated, the positioning preparation work needs a lot of time, the operation process is very complex and is not easy to master, and the positioning device is difficult to popularize and use in vast primary hospitals. 3. Neuro-navigation technique or robotics (ROSA robot): the method is also called frameless neuroimaging navigation technology, which is a precise real-time image navigation system formed based on the CT or MR image data analysis of scalp mark points so as to guide a surgeon to puncture, and has expensive equipment and difficult application to cerebral hemorrhage operation in most primary hospitals. 4. 3D-Slicer combined sina software or 3D printing auxiliary positioning: the preoperative CT scanning, software analysis modeling, 3D printing positioning module, software technology threshold and application process are complex. 5. And (3) CT scanning positioning: after the marking points are pasted on the scalp of the CT room, the CT scanning is carried out for confirmation, then the marking is drawn, and the positioning is often more accurate, but the method is not suitable for emergency patients. In primary hospitals, patients with spontaneous intracerebral hematoma and traumatic intracranial hematoma are more, the disease condition is more critical, the operation is difficult for seconds, the accurate positioning is often not needed, and the positioning is completely dependent on years of experience of the operator, so that a simple and easy-to-learn positioning ruler is researched, is necessary for neurosurgery doctors in young primary hospitals, and is easy to popularize and use in vast primary hospitals.

SUMMERY OF THE UTILITY MODEL

Aiming at the technical defects, the utility model aims at providing a TFCT craniocerebral positioning ruler, which is based on the positioning method in the Chinese invention patent with the application number of 2019101752535, namely 'a TFCT type craniocerebral positioning puncture auxiliary device and a use method thereof', and has the advantages of simple principle and convenient use.

In order to solve the technical problem, the utility model adopts the following technical scheme:

a TFCT craniocerebral positioning ruler comprises a transverse ruler and two vertical rulers which are arranged on the transverse ruler in a sliding mode, scale marks are arranged on the surfaces of the transverse ruler and the vertical rulers, at least one sliding block is arranged on each of the transverse ruler and the vertical rulers, a groove is formed in each sliding block, and a thin cylindrical indicator needle is arranged in each groove in a sliding mode.

Preferably, one end of the vertical ruler, which is close to the transverse ruler, is provided with a slide rail matched with the transverse ruler.

Preferably, the axis of the pointer on the horizontal ruler is parallel to the scale mark on the horizontal ruler, and the axis of the pointer on the vertical ruler is parallel to the scale mark on the vertical ruler.
