Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical technology, and in particular to a teaching kit for the sphenoid wing. Background Technology
[0002] In neurosurgery, whether for vascular diseases or aneurysms, the anatomy of the sellar region at the base of the skull is relatively complex, making it crucial for medical staff to improve their understanding of bone anatomy. However, learning in this type of surgery involves two main approaches: one is using atlases or books, which lacks visual appeal and doesn't allow for hands-on training in bone resection; the other is learning through models, but currently there are no suitable teaching models, and traditional two-dimensional atlases and static models cannot dynamically demonstrate the structure and spatial relationships of the lesser wing of the sphenoid bone, only providing a reconstruction without allowing for hands-on training in bone resection. Utility Model Content
[0003] The purpose of this invention is to provide a sphenoid wing training kit to solve the aforementioned technical problems in the prior art.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] This utility model provides a sphenoid wing teaching kit, comprising a sphenoid bone platform teaching model, a split model, and a practical grinding model manufactured using 3D printing technology; wherein:
[0006] The sphenoid bone platform teaching model is an enlarged model of the lesser wing of the sphenoid bone in the central skull base, used to assist teaching videos in recognizing key anatomical structures.
[0007] The split model is a unilateral model of the sphenoid wing, which is composed of several bone block models. The bone block models can be disassembled and are used to help understand the configuration and correspondence between the bone blocks of the sphenoid wing in conjunction with the teaching video.
[0008] The practical grinding model is a practical model of the sphenoid wing's pterional approach, used for grinding training on the practical model based on the teaching video.
[0009] This utility model of a sphenoid wing teaching kit includes three models, each with a different purpose: a magnified sphenoid platform demonstration model for thorough understanding of key anatomical structures with accompanying instructional videos; a magnified split model for learners to understand the structural composition of the sphenoid wing and the correspondence between its parts with accompanying instructional videos; and a practical grinding model for learners to conduct hands-on grinding training based on the instructional videos. By using these multiple models together, observation from any angle is possible, and the disassembly of each bone block is convenient, providing a very intuitive understanding of the anatomy of the sellar region of the skull base.
[0010] Based on the above technical solution, the present invention can be further improved as follows.
[0011] As a further improvement of this utility model, the magnification of the sphenoid platform teaching model is 2 times.
[0012] The lesser wing of the sphenoid bone is located deep in the base of the skull and is closely connected to structures such as the optic nerve canal and the carotid artery. Traditional whole models cannot clearly display details due to occlusion. This utility model uses a 2x scale sphenoid bone platform teaching model, which facilitates observation and allows for clear display of details.
[0013] As a further improvement of this utility model, the magnification of the split model is 3.5 times.
[0014] As a further improvement of this utility model, the split model includes seven bone block models, namely, the orbital apex roof bone block, the superior orbital fissure roof bone block, the optic canal roof bone block, the anterior clinoid process base bone block, the anterior clinoid process bone block, the optic rod bone block, and the sphenoid body; wherein: the superior orbital fissure roof bone block and the optic canal roof bone block are detachably connected to the orbital apex roof bone block; the anterior clinoid process base bone block is detachably connected to the superior orbital fissure roof bone block and the optic canal roof bone block; the anterior clinoid process bone block and the optic rod bone block are detachably connected to the anterior clinoid process base bone block; and the optic rod bone block is detachably connected to the sphenoid body.
[0015] The modular model of this invention can be gradually decomposed to achieve observation without blind spots and avoid missing key anatomical relationships.
[0016] As a further improvement of this invention, all bone block models are detachably connected by magnetic blocks.
[0017] As a further improvement of this utility model, the practical grinding model includes a substrate and a 1:1 scale partial model of the sphenoid wing fixed on the substrate; the partial model of the sphenoid wing is in the position of the wingtip approach.
[0018] This utility model's practical grinding model is 3D printed and accurately reproduces the lesser wing of the sphenoid bone. In skull base surgery, the grinding of the lesser wing of the sphenoid bone needs to precisely avoid the optic nerve and carotid artery. Novices may find it difficult to control the force and angle in the overall model or during surgery. The grinding model allows for repeated grinding of the anterior clinoid process separately, reducing the risk of accidental injury during surgery.
[0019] As a further improvement of this utility model, it also includes a fully transparent intracranial simulation deep space box for fixing the practical abrasion model; the fully transparent intracranial simulation deep space box includes a cubic hollow box body, an operating port, a positioning plate, and a box door; wherein:
[0020] The operating port is located at the top of the box and is used to simulate a surgical incision;
[0021] The positioning plate is installed in the inner cavity of the box to simulate the intracranial position of the actual ablation model;
[0022] The box door is openable and closable on one side of the box body for taking out and putting in the practical grinding model.
[0023] By using a fully transparent intracranial deep space simulation box, the internal space of which is adapted to the size of the skull, when the actual drilling model is placed in the fully transparent intracranial deep space simulation box, its position is the same as the intracranial position during conventional surgery, which makes it convenient for learners to perform the simulated drilling surgery process in the most realistic way.
[0024] As a further improvement of this utility model, the positioning plate is provided with a limiting groove, and the two sides of the substrate are slidably disposed in the limiting groove; the opposite side walls of the box are provided with a first slot, and the positioning plate is detachably connected to the box through the first slot; the substrate is also provided with a locking member for locking or releasing the position of the actual grinding model.
[0025] As a further improvement of this utility model, the locking component includes a locking hole, a locking pin, and a handle; wherein:
[0026] The locking hole is a threaded hole and is formed on the substrate;
[0027] The handle is connected to the locking pin;
[0028] The locking pin is screwed onto the locking hole. The position is locked or released by adjusting the screwing depth of the locking pin to abut against or disengage from the positioning plate.
[0029] As a further improvement of this utility model, a second slot is provided on the box body, and the box door is detachably connected to the box body through the second slot. Attached Figure Description

[0046] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0047] like Figures 1-14 As shown, this utility model provides a sphenoid wing teaching kit, including a sphenoid bone platform teaching model 1 processed using 3D printing technology, a split model, and a practical grinding model; wherein:
[0048] The sphenoid bone platform teaching model 1 is an enlarged model of the lesser wing of the sphenoid bone in the central skull base, used to help students understand key anatomical structures in the teaching videos.
[0049] The split model is a single-sided model of the sphenoid wing, which is composed of several bone block models. The bone block models can be disassembled and are used to help understand the configuration and correspondence between the bone blocks of the sphenoid wing in conjunction with the teaching video. Specifically, the split model simulates a single-sided part of the overall symmetrical structure of the sphenoid platform teaching model 1.
[0050] The practical grinding model is a sphenoid wing pterion approach model, used for grinding training based on instructional videos. Specifically, the practical grinding model simulates approximately one-quarter of the overall structure of the sphenoid platform teaching model 1.
[0051] This utility model of a sphenoid wing teaching kit includes three models, each with a different purpose: a magnified sphenoid platform demonstration model 1 for thorough understanding of key anatomical structures with accompanying teaching videos; a magnified split model for learners to understand the structural composition of the sphenoid wing and the correspondence between its parts with accompanying teaching videos; and a practical grinding model for learners to conduct hands-on grinding training based on the teaching videos. By using multiple models together, observation can be performed from any angle, and the disassembly of each bone block is convenient, providing a very intuitive understanding of the anatomy of the sellar region of the skull base.
[0052] For ease of observation, in this embodiment, the magnification of the sphenoid bone platform teaching model 1 is 2 times.
[0053] It should be noted here that the magnification factor refers to the ratio of the size of each part of the model to the actual size of the human skeleton.
[0054] Because the lesser wing of the sphenoid bone is located deep in the base of the skull and is closely connected to structures such as the optic nerve canal and the carotid artery, traditional whole models cannot clearly display details due to occlusion. This utility model uses a 2x scale sphenoid bone platform teaching model 1, which facilitates observation and allows for clear display of details.
[0055] To facilitate observation, this invention employs a split model, which can disassemble the sphenoid bone into multiple pieces. Since the disassembled bone pieces are still too small to be clearly observed, in this embodiment, the magnification of the split model is 3.5 times.
[0056] As a further improvement to this utility model, such as Figure 2 and Figure 14 As shown, the modular model comprises seven bone blocks: orbital apex roof bone block 2, superior orbital fissure roof bone block 3, optic canal roof bone block 4, anterior clinoid process base bone block 5, anterior clinoid process bone block 6, optic rod bone block 7, and sphenoid body 8. Specifically: superior orbital fissure roof bone block 3 and optic canal roof bone block 4 are detachably connected to orbital apex roof bone block 2; anterior clinoid process base bone block 5 is detachably connected to superior orbital fissure roof bone block 3 and optic canal roof bone block 4; anterior clinoid process bone block 6 and optic rod bone block 7 are detachably connected to anterior clinoid process base bone block 5; and optic rod bone block 7 is detachably connected to sphenoid body 8. The seven bone blocks can be disassembled or assembled.
[0057] The modular model of this invention can be gradually decomposed to achieve observation without blind spots and avoid missing key anatomical relationships.
[0058] As an optional embodiment of this utility model, all bone block models are detachably connected by magnetic blocks.
[0059] As an optional embodiment of this utility model, several magnetic blocks are provided on each connecting surface of each bone block model, and the magnetic poles of the magnetic blocks on the two bone block models to be connected are opposite; of course, another embodiment can also be adopted, in which magnetic blocks are provided on some bone block modules and metal pillars are provided on other bone block models, and the metal pillars and magnetic blocks are magnetically attracted to each other to realize the connection between bone block models.
[0060] In this embodiment, the practical grinding model includes a substrate 10 and a 1:1 scale partial model 9 of the sphenoid wing fixed on the substrate 10; the partial model 9 of the sphenoid wing is the position of the pterional approach.
[0061] The 9-inch, 1:1 scale model of the lesser wing of the sphenoid bone realistically recreates the lesser wing, complete with the carotid artery, optic nerve, and oculomotor nerve. Positioned for the pterional approach, it allows for microscopic ablation. Its advantages include realism, allowing observation from any angle, and providing a highly intuitive understanding of the anatomy of the sellar region of the skull base.
[0062] Furthermore, the partial model 9 of the lesser wing of the sphenoid bone includes the anterior clinoid process, decompression of the optic canal, and treatment of the optic column. Users can practice grinding on this 1:1 model based on the instructional videos, experiencing the steps, angles, and extent of grinding away structures in the sphenoid bone region.
[0063] For ease of observation, the substrate 10 in this invention is made of a transparent material.
[0064] This utility model's practical grinding model is 3D printed and accurately reproduces the lesser wing of the sphenoid bone. In skull base surgery, the grinding of the lesser wing of the sphenoid bone needs to precisely avoid the optic nerve and carotid artery. Novices may find it difficult to control the force and angle in the overall model or during surgery. The grinding model allows for repeated grinding of the anterior clinoid process separately, reducing the risk of accidental injury during surgery.
[0065] Furthermore, it also includes a fully transparent intracranial deep space simulation box 100 for fixing the practical ablation model; the fully transparent intracranial deep space simulation box 100 includes a cubic hollow box body 101, an operating port 102, a positioning plate 103, and a box door 104; wherein:
[0066] The operating port 102 is located on the top of the box body 101 and is used to simulate a surgical incision;
[0067] The positioning plate 103 is installed in the inner cavity of the box 101 to simulate the intracranial position of the actual grinding model;
[0068] The door 104 is openable and closable on one side of the box body 101 for taking out and putting in the practical grinding model.
[0069] It should be noted that, for ease of observation, the positioning plate 103 is also made of transparent material.
[0070] By using a fully transparent intracranial simulation deep space box 100, the internal space of which is adapted to the size of the skull, when the actual drilling model is placed in the fully transparent intracranial simulation deep space box 100, its position is the same as the intracranial position during conventional surgery, which makes it easier for learners to perform the simulated drilling surgery process in the most realistic way.
[0071] Furthermore, the positioning plate 103 is provided with a limiting groove 105, and the base plate 10 is slidably disposed in the limiting groove 105 on both sides; the opposite side walls of the box body 101 are provided with a first slot 106, and the positioning plate 103 is detachably connected to the box body 101 through the first slot 106; the base plate 10 is also provided with a locking member 107, which is used to lock or release the position of the actual grinding model.
[0072] As a further improvement of this utility model, the locking member 107 includes a locking hole, a locking pin, and a handle; wherein:
[0073] The locking hole is a threaded hole and is formed on the substrate 10;
[0074] Connect the handle to the locking pin;
[0075] The locking pin is screwed onto the locking hole. The position is locked or released by adjusting the screwing depth of the locking pin to abut or disengage from the positioning plate 103.
[0076] As a further improvement of this utility model, a second slot 108 is provided on the box body 101, and the box door 104 is detachably connected to the box body 101 through the second slot 108.
[0077] Applications of the fully transparent intracranial deep space simulation box 100:
[0078] 1. Fully transparent intracranial space simulating deep space;
[0079] 2. Simulate the incision to provide a realistic intracranial surgical path;
[0080] 3. Fully transparent field of view, allowing for precise observation of details from every angle.
