Description

Technical Field

[0001] This invention relates to the field of anatomical medical instruments, specifically a fixation and opening device for brain extraction. Background Technology

[0002] Head and neck applied anatomy and intracranial applied anatomy have become important disciplines for medical students. The excised human head and neck skull (hereinafter referred to as the human head and neck skull) is the most important experimental equipment for teaching and research in head and neck applied anatomy and intracranial applied anatomy. Students need to dissect the human head and neck skull to achieve practical learning objectives. Brain specimens, which are indispensable for medical students in their studies, need to be obtained by craniotomy and prepared.

[0003] However, some problems still exist in the process of craniotomy to extract the brain.

[0004] Question 1: The human head and neck are approximately spherical in shape. Spherical objects are characterized by an unstable center of gravity, are prone to rolling, and are difficult to place stably. Applied anatomy of the head and neck, and intracranial anatomy, requires the human head and neck to be placed in a specific position. After being placed in the required anatomical position, the skull is dissected layer by layer. Traditionally, intracranial dissection often requires chiseling open the skull. If the placement is incorrect, dissection becomes difficult or even impossible. If the skull is not securely fixed, it is easy to damage the brain when chiseling open the skull. To obtain a brain specimen, a hacksaw is needed to cut open the skull to remove the brain tissue. When cutting open the skull, the hacksaw blade often breaks because the human head is not securely fixed and rolls, or the surface structure of the brain is damaged due to cutting too deep, making the removed brain unusable.

[0005] Question 2: During the craniotomy, bone fragments and blood often occur, which can affect the operator's vision, the progress and speed of the craniotomy, and also make the post-craniotomy cleaning work inconvenient.

[0006] Therefore, there is an urgent need for a fixation and opening device for brain extraction to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a fixation and opening device for brain retrieval, in order to solve the problems mentioned in the background art, such as the instability of the skull's center of gravity during the sawing process, the tendency for the skull to roll and be difficult to place stably, the frequent rolling due to the insecure fixation of the human skull leading to the breakage of the hacksaw blade, or the damage to the surface structure of the brain due to excessive sawing, resulting in the unusable brain after retrieval, and the fact that bone fragments and blood often accompany the craniotomy process, affecting the operator's vision, the progress and speed of the craniotomy, and also making the cleaning work after the craniotomy inconvenient.

[0041] Working principle:

[0042] When in operation, the operator pulls the operating lever 304 upwards, causing the cutting assembly 302 to rise as a whole, leaving sufficient space above the placement assembly 201. The head is then placed on the first fixing slot 209, and the bolt 223 is tightened clockwise. At this time, the bolt 223 abuts against the first connecting block 217, causing the clamp plate 218 to move towards the second clamping plate 215 to clamp and fix the head. Then, the operating lever 304 is pulled downwards to lower the cutting assembly 302. At this time, the fixing frame 330 abuts against the top of the head, and the spring 329 is compressed, causing elastic deformation and contraction, ensuring that the fixing frame 330 is stably fixed to the top of the head. At this time, the second motor 322 is started via the control panel 400, driving the second connecting frame 316 to rotate, which in turn drives the electric saw blade 324 to rotate. Simultaneously, the first motor 313 is operated via the control panel 400. The second connecting frame 316 rotates, thereby driving the electric saw blade 324 to perform a 360-degree circular slitting operation. At the same time, the control panel 400 controls the operation of the electric telescopic rod 317, which drives the retaining ring 319 to control the slitting depth of the electric saw blade 324. Meanwhile, the laser rangefinder 311 on the upper part monitors the slitting distance accuracy in real time. During the slitting process, the control panel 400 controls the water pump to supply water to the two sets of first connecting pipes 227. During the operation, the nozzle 228 sprays cleaning fluid to clean the head, ensuring visibility during the operation. After cleaning the head with cleaning fluid, the blood and water collected through the first connecting frame 211 enter the collection box 105 for collection. When the slitting work is completed, the collection box 105 is pulled down with the help of the pull handle 107 to remove the collection box 105 and pour out the blood and water inside for cleaning. This completes the operation.
