Head fixator

Abstract

The invention discloses a head fixator which comprises a locking mechanism, a stand column base assembly and a coronal fixator, the locking mechanism is installed on a stand column of the stand column base assembly and clamped at the upper end of the stand column through an air spring upper support of the locking mechanism, and a connecting rod of the coronal fixator is installed in a hole of a ball rod of the locking mechanism. The head model and the head specimen are connected together and locked through the locking handle on the coronal fixator, the structure is simple, the head model and the head specimen cannot turn over when force is applied, and in the training process of intern doctors or the test process of medical workers, the head model or the head specimen is placed on the coronal fixator. The device can well assist internship doctors or medical workers in completing related internship or preoperative operation plan verification, shortens training time, reduces training cost, and has the potential advantages of shortening operation time, reducing pain of patients, reducing labor intensity of doctors and reducing operation cost.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a cranial immobilizer. Background technique [0002] Before minimally invasive surgery or when training interns, a cephalostat is required to fix the skull model. Specifically, head immobilizers need to meet the following requirements: 1. Place and fix the skull model on the fixture, train interns, shorten training time, improve training quality, and reduce training costs; 2. Before a difficult operation, if necessary, the surgeon needs to verify the operation plan, first verify it on the skull specimen, and place the skull specimen on the fixator so that the doctor can simulate the operation and achieve the same effect as the operation process. Successfully provide reliable guarantee, indirectly reduce the pain of patients, save operation time and operation cost; 3. Provide a training platform for minimally invasive surgery to solve the urgent needs of intern training an...

Problems solved by technology

In the prior art, there is a fixation device similar to a coronal fixator, such as the Chinese invention patent with the application number 201310276271.5 and the name "temporal bone and skull anatomy fixation device". Although it also has a locking and fixing function, its locking mechanism is complicated. The force required when locking is relatively large, and it is easy to fall over when applying force
