Description

Technical Field

[0001] This invention relates to the field of anatomy, and more particularly to an auxiliary tool and route planning device for medical anatomy. Background Technology

[0002] Medical anatomy is divided into two categories: one is the study and explanation of the normal anatomical structure of the human body, known as human anatomy; the other is pathological anatomy, or autopsy for short, which involves a comprehensive pathological dissection of the deceased's body. Through observation with the naked eye and microscope, and even with the aid of some pathological techniques, the changes that have occurred in the body's tissues and organs are studied to clarify the pathological diagnosis of the disease and determine the cause of death. This further clarifies the etiology and pathogenesis of the disease and helps to explain the clinical manifestations before death and to judge whether the treatment measures were appropriate or reasonable. It is one of the basic research methods of pathology, and dissecting instruments are an important tool in medical anatomy.

[0003] Before using medical dissection instruments, the instruments need to be manually disinfected. After disinfection, they are operated and used by holding the handle. In actual operation, the blade of the dissection instrument is always in an extended state, and the medical dissection of the corpse is performed through the blade.

[0004] To improve the protective performance of dissecting scalpels, the blade section mainly adopts an anti-slip structure and an extension structure to enhance the protective performance of the scalpel section. When using it, the protective sheath needs to be opened first to expose the blade. After holding the handle, the blade is used to dissect the area. Different parts of the skin need to be cut to different depths. The actual depth of dissection is controlled by the degree of manual pressure. However, the dissecting scalpel itself is not convenient to adaptively adjust the cutting depth of the blade section according to the user's needs.

[0005] Therefore, it is necessary to provide an auxiliary tool and route planning device for medical anatomy to solve the above-mentioned technical problems. Summary of the Invention

[0058] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0059] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0060] This invention provides an auxiliary tool for medical anatomy.

[0061] Please refer to the following: Figures 1 to 4 In the first embodiment of the present invention, the auxiliary tool used for medical anatomy includes:

[0062] The tool handle 1 has a shrinkage groove 101 and a through hole 102. The shrinkage groove 101 is connected to the outside of the tool handle 1, and the shrinkage groove 101 is connected to the through hole 102. The through hole 102 is also connected to the outside of the tool handle 1.

[0063] The pressing assembly 2 includes a pressing rod 21, a connecting shaft 22, and a transmission rod 23. One end of the pressing rod 21 is installed in the through hole 102 and is rotatably connected to the knife handle 1. The other end of the pressing rod 21 is rotatably connected to one end of the transmission rod 23 through the connecting shaft 22. The other end of the transmission rod 23 is inserted into the shrinkage groove 101 through the through hole 102.

[0064] The connecting frame 3 is installed in the shrinkage groove 101 and is slidably connected to the tool holder 1. The connecting frame 3 has a U-shaped structure and a sliding shaft 31 is fixed inside the connecting frame 3. The other end of the transmission rod 23 is rotatably mounted on the sliding shaft 31.

[0065] Blade 4, which is fixed on the connecting frame 3 and located in the shrinkage groove 101;

[0066] Elastic element 5, which elastically connects the handle 1 and the connecting frame 3.

[0067] When dissection is required, the handle 1 can be held with two fingers, with the end of the handle 1 in contact with the skin to be dissected. The pressing force of the pressing component 2 can be controlled by one finger, which controls the length of the blade 4 extending from the end of the handle 1, thereby controlling the dissection depth to meet the needs of dissection research. When the pressing component 2 is released, the elastic element 5 can automatically retract the blade 4, increasing the concealment function of the blade 4 and improving the safety of the blade 4 when it is stored.

[0068] In this embodiment, the port of the knife handle 1 is an arc-shaped structure, which can fit against the surface of the dissected sample, thereby ensuring smooth movement.

[0069] The tool holder 1 port is located at the opening end of the contraction groove 101, such as... Figure 2 The indicator end of the central contraction groove 101 is the open end.

[0070] In this embodiment, the U-shaped connecting frame 3 provides space for the insertion of the transmission rod 23, and the transmission rod 23 slides in contact with the connecting frame 3, ensuring the stability of the connection between the transmission rod 23 and the sliding shaft 31.

[0071] In this embodiment, the blade 4 is a medical anatomical blade structure.

[0072] In this embodiment, the elastic element 5 is preferably a spring, but it can also be other components with elastic extension and contraction functions.

[0073] Please refer to the following: Figure 1 and Figure 3 The connecting shaft 22 passes through the pressing rod 21 and extends to both sides of the pressing rod 21, and the length of the connecting shaft 22 is greater than the width of the through hole 102.

[0074] When the pressing rod 21 is rotated counterclockwise, the connecting shaft 22 can abut against the tool holder 1 without entering the through hole 102, thereby increasing the rotation limit of the pressing rod 21 and providing a stable maximum cutting distance.

[0075] Please refer to the following: Figure 1 and Figure 5 The handle 1 is also provided with a sliding hole 103, which is connected to the shrinkage groove 101. The sliding shaft 31 passes through the connecting frame 3 and extends into the sliding hole 103. The sliding shaft 31 is slidably connected to the handle 1. The auxiliary tool for medical anatomy also includes a scale plate 6, which is fixed on the handle 1. The sliding shaft 31 is aligned with the scale plate 6.

[0076] The scale plate 6, used in conjunction with the sliding shaft 31, facilitates the indication of the extension distance of the blade 4, making it easier to observe during the pressing process and better control the depth of dissection.

[0077] In this embodiment, the size indicated by the scale plate 6 is relative to the length of the blade 4 extending from the opening end of the retraction groove 101, wherein, in the initial state, the blade 4 is fully retracted within the retraction groove 101;

[0078] Furthermore, when the pressing rod 21 is pressed in the forward direction, the pressing rod 21 can push the sliding shaft 31 forward by connecting the rotating shaft 22 and the transmission rod 23. At the same time as the sliding shaft 31 moves forward, the connecting frame 3 and the blade 4 move forward. The blade 4 gradually extends out from the opening end of the shrinking groove 101. The dimension of the sliding shaft 31 corresponding to the dimension indicated on the scale plate 6 gradually increases, indicating the depth of the blade 4.

[0079] The working principle of the auxiliary tool for medical anatomy provided in this embodiment is as follows:

[0080] Please see Figure 6 The principle of pressing to eject the blade:

[0081] Referring to Figure (6a), in the initial state, the pressing lever 21 is in the raised state, the blade 4 is in the retracted state, the end of the handle 1 is in contact with the sample to be dissected, the blade 4 is facing the sample, and the pressing lever 21 is away from the sample, which facilitates manual operation.

[0082] Referring to Figures (6a) to (6b), the pressing rod 21 begins to press, the pressing rod 21 rotates counterclockwise, the transmission rod 23 rotates clockwise around the connecting shaft 22, the transmission rod 23 drives the connecting frame 3 to move forward through the sliding shaft 31, the blade 4 moves forward, the blade 4 extends from the opening end of the shrinkage groove 101, the blade 4 begins to extend, and the extension depth is controlled by the pressing force of the pressing rod 21.

[0083] Referring to Figures (6b) to (6c), press the lever 21 to continue pressing. The lever 21 drives the connecting shaft 22 to abut against the tool holder 1. The lever 21 is fixed and the blade 4 extends to the maximum depth.

[0084] Referring to Figures (6c) to (6d), when the pressing rod 21 is released, the elastic element 5 retracts elastically, the connecting frame 3 retracts and resets, the blade 4 retracts, and the sliding shaft 31 pushes the transmission rod 23, the connecting shaft 22 and the pressing rod 21 to rotate and reset, returning to the initial state, thus realizing the automatic retraction of the blade 4.

[0085] Please see Figure 7 The principle of blade insertion indication:

[0086] Referring to Figure (7a), in the initial state, the pressing rod 21 has no action, and the sliding shaft 31 is indicated at the 0 mark on the scale plate 6;

[0087] Referring to Figure (7b), when the pressing rod 21 is pressed for the first time, the blade 4 extends and the sliding shaft 31 moves. The reading of the sliding shaft 31 relative to the scale plate 6 increases. The reading of the scale plate 6 is the same as the distance the blade 4 extends, which makes it convenient to understand the cutting depth of the blade 4 during the dissection process.

[0088] Referring to Figure (7c), when the pressing lever 21 is pressed to the bottom, the blade 4 extends to its maximum range, the slide shaft 31 moves to its maximum range, and the reading of the slide shaft 31 on the scale plate 6 is the maximum value. This maximum value is the maximum distance that the blade 4 can extend, which meets the cutting requirements of the maximum depth.

[0089] Second embodiment:

[0090] Since the handle 1 as a whole needs to be stored and folded away when not in use, and the protruding pressing rod 21 increases the space occupied by the handle 1, it is inconvenient to fold and fold away the blade 4 at the same time. Therefore, this application also provides another auxiliary tool for medical anatomy that can fold and fold away the pressing rod 21 while the blade 4 is folded away.

[0091] Please refer to the following: Figures 8 to 9 Based on the first embodiment of the present invention, which provides an auxiliary tool for medical anatomy, the second embodiment of the present invention proposes another auxiliary tool for medical anatomy. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0092] Specifically, the second embodiment of the present invention provides an auxiliary tool for medical anatomy that differs in that the auxiliary tool for medical anatomy also includes an elastic telescopic member 7. The fixed end of the elastic telescopic member 7 is rotatably mounted on the connecting shaft 22. The elastic telescopic member 7 passes through the through hole 102 and extends into the contraction groove 101. The telescopic end of the elastic telescopic member 7 is rotatably mounted on the sliding shaft 31.

[0093] When the blade 4 and the handle 1 need to be retracted, the elastic telescopic component 7 can support the connecting shaft 22 to rotate clockwise along the pressing rod 21 and press against the handle 1, so that the pressing rod 21 can be folded up when not in use. At the same time, the blade 4 itself is in a retracted state, reducing the space occupied by the equipment when it is not in use, and making it convenient for storage.

[0094] In this embodiment, the elastic telescopic member 7 is disposed in two

[0095] In this embodiment, by lifting the connecting shaft 22 clockwise, the pressing rod 21 rotates clockwise, the connecting frame 3 causes the blade 4 to retract slightly, and the connecting shaft 22 abuts against the handle 1, which, together with the elastic element 5, locks the blade 4 after it is retracted.

[0096] In this embodiment, the sliding hole 103 provides space for the sliding shaft 31 to adjust its contraction.

[0097] In this embodiment, the elastic telescopic member 7 is a type of spring telescopic structure, which provides support for increasing the distance between the connecting shaft 22 and the sliding shaft 31.

[0098] In this embodiment, the elastic telescopic member 7 is the preferred option for the transmission rod 23. If the elastic telescopic member 7 is selected, the transmission rod 23 is no longer needed, and either one can be selected.

[0099] Please refer to it again. Figure 3 The pressing rod 21 is provided in two sets, and the two sets of pressing rod 21 are symmetrically arranged on both sides of the elastic telescopic member 7, and the two sets of pressing rod 21 are arranged in parallel.

[0100] The pressing range of the pressing lever 21 is increased to improve the operating comfort when pressing with one finger. The gap between the two sets of pressing levers 21 provides sufficient room for the elastic telescopic component 7 to move, so that the elastic telescopic component 7 can rotate adaptively when the pressing lever 21 rotates clockwise.

[0101] In this embodiment, a rubber pad may be added to the pressing area of ​​the pressing rod 21. The pressing area is the area on the surface of the pressing rod 21, not the gap between the two pressing rods 21.

[0102] Please refer to it again. Figure 8 The auxiliary tool for medical anatomy also includes a locking cover 8, which is slidably mounted on the handle 1 and matches the surface of the pressing rod 21.

[0103] When the pressing rod 21 is pressed counterclockwise, the locking cover 8 can slide to cover the pressing rod 21 to lock the blade out. When the pressing rod 21 is retracted clockwise, the locking cover 8 can slide to cover the pressing rod 21 to lock the blade back in.

[0104] In this embodiment, the locking cover 8 is used to add locking when the pressing rod 21 is fully extended or retracted, so as to maintain the stability of the blade 4 in the required fixed state.

[0105] In this embodiment, the locking cover 8 has an inclined slot for connecting the pressing rod 21 and locking it in place, thus ensuring the stability of the pressing rod 21 when it is locked.

[0106] Please refer to the following: Figure 8 and Figure 10 The auxiliary tool used in medical anatomy also includes an elastic buffer 9, the fixed end of which is fixed to the handle 1, and the buffer end of which abuts against the locking cover 8.

[0107] When the pressing rod 21 is rotated clockwise, the locking cover 8 automatically locks onto the pressing rod 21 without requiring manual operation.

[0108] In this embodiment, the locking cover 8 and the elastic buffer 9 are installed in a movable manner, so that the locking cover 8 can be freely slid and adjusted according to usage requirements.

[0109] In this embodiment, the elastic buffer 9 is another type of spring telescopic structure, which provides elastic support for the extension and retraction of the locking cover 8.

[0110] Please combine Figure 11 and Figure 12 In a preferred embodiment, the sliding shaft 31 is provided with a threaded groove 311, and the threaded knob 32 is threadedly mounted on the sliding shaft 31 through the threaded groove 311. A locking ring 321 is fixed on the threaded knob 32, and the locking ring 321 matches the scale plate 6.

[0111] The length of the blade 4 can be set in advance according to the needs of use. After tightening the threaded knob 32, the threaded knob 32 is locked on the scale plate 6 by the locking ring 321, and the sliding shaft 31 is fixed, so as to fix the length of the blade 4 when it is extended.

[0112] In an optional embodiment, the threaded knob 32 can replace the presence of the locking cover 8 and the elastic buffer 9, or both can be present simultaneously.

[0113] In this embodiment, the locking ring 321 is preferably a rubber ring structure to increase the friction during locking;

[0114] The locking ring 321 can be directly locked onto the scale plate 6, or it can be locked onto the tool holder 1.

[0115] The working principle of the auxiliary tool used in medical anatomy provided in this embodiment is as follows:

[0116] See Figure 13 Press lever 21 to extend and lock the blade;

[0117] Referring to Figure (13a), when the pressing lever 21 is not in motion, the blade 4 is retracted and the locking cover 8 is not in contact with the pressing lever 21;

[0118] Referring to Figure (13b), after pressing the lever 21 counterclockwise, manually control the locking cover 8 to move forward. The locking cover 8 presses against the lever 21, thus locking the blade 4 after it is fully extended.

[0119] See Figure 14 Press lever 21 to retract and lock the blade:

[0120] Referring to Figure (14a), when the pressing lever 21 is not in motion, the blade 4 retracts and the locking cover 8 rests against the elastic buffer 9;

[0121] From Figure (14a) to Figure (14b), the pressing rod 21 rotates clockwise, and the connecting frame 3 causes the blade 4 to retract slightly;

[0122] From Figure (14b) to Figure (14c), the pressing rod 21 continues to rotate, and the elastic telescopic member 7 contacts the locking cover 8;

[0123] From Figure (14c) to Figure (14d), as the pressing rod 21 continues to rotate, the elastic telescopic member 7 pushes the locking cover 8 backward, and the locking cover 8 elastically contracts on the elastic buffer member 9.

[0124] From Figure (14d) to Figure (14e), when the pressing lever 21 is rotated to the folded position, the pressing lever 21 separates from the locking cover 8. The locking cover 8 moves forward under the elastic action of the elastic buffer 9, and the locking cover 8 automatically locks above the pressing lever 21.

[0125] The present invention also provides a route planning device, including the aforementioned auxiliary tool for medical anatomy; the route planning device further includes:

[0126] Scanning module 100, analysis and diagnosis module 200, and simulated anatomy module 300;

[0127] The scanning module 100 uses CT and MRI to perform a comprehensive scan of the specimen mounted on the specimen bed;

[0128] The analysis and diagnosis module 200 includes a pathological analysis unit 210, a pathological diagnosis unit 220, and a student pathology unit 230. The pathological analysis unit 210 is used to cooperate with the pathological diagnosis unit 220 to diagnose the pathology of the specimen, and the student pathology unit 230 provides students with pathological research and judgment.

[0129] The simulated anatomy module 300 includes a data modeling unit 310, an online simulated anatomy unit 320, an image conversion unit 330, a layered projection unit 340, and an anatomy guidance unit 350. The data modeling unit 310 is used to perform three-dimensional modeling and imaging on the scanned data. The online simulated anatomy unit 320 is used for students to simulate anatomy experiments. The image conversion unit 330 is used to display and analyze the three-dimensional images generated by the data modeling unit 310. The layered projection unit 340 is used to project the received information layer by layer onto the specimen to form an anatomical route, which provides route planning for the anatomy auxiliary tools used in medical anatomy. The anatomy guidance unit 350 is used for teaching and explaining to students.

[0130] In this embodiment, the scanning module 100 uses CT and MRI to perform a comprehensive scan of the specimen mounted on the specimen bed. The scanned data is transmitted to the data modeling unit 310 for data modeling to form a three-dimensional modeling image. The image is then transmitted to the online simulation anatomy unit 320 to provide students with online simulation anatomy teaching. The dissection route is recorded inside the layered projection unit 340 after the dissection.

[0131] The output of the data modeling unit 310 is connected to the online simulation anatomy unit 320, and the output of the data modeling unit 310 is connected to the image conversion unit 330. The output of the image conversion unit 330 is connected to the layered projection unit 340. The input of the layered projection unit 340 is connected to the output of the online simulation anatomy unit 320, and the output of the layered projection unit 340 is connected to the anatomy guidance unit 350. The image conversion unit 330 displays and analyzes the three-dimensional image generated by the data modeling unit 310, which is used by doctors to plan the route for specimen dissection. The route planning is a standard anatomical route for teaching. The anatomical route is stored inside the layered projection unit 340 through the image conversion unit 330. The layered projection unit 340 projects the anatomical route simulated by the student and the standard anatomical route planned by the doctor onto the surface of the specimen on the bed structure through a projection device, which facilitates teaching and reading for students.

[0132] When conducting anatomical studies on medical cadaver samples, in order to better teach and simulate, existing 3D modeling is used to quickly project anatomical imaging areas. At the same time, virtual modeling technology is used to display the cadaver's structural images on computer or mobile phone software for students' virtual dissection. After the virtual dissection, users need to observe and learn in a physical dissection laboratory.

[0133] The working principle of the route planning device provided by this invention is as follows:

[0134] The specimen mounted on the specimen bed is scanned using CT and MRI. The scanned data is transmitted to the data modeling unit 310 for data modeling to form a three-dimensional model image. The image is then transmitted to the online simulation dissection unit 320 to provide students with online simulated dissection. The dissection route is recorded inside the layered projection unit 340.

[0135] The image conversion unit 330 displays and analyzes the three-dimensional image generated by the data modeling unit 310, which is used by doctors to plan the route for specimen dissection. The route planning is a standard anatomical route for teaching. The anatomical route is stored in the layered projection unit 340 through the image conversion unit 330. The layered projection unit 340 projects the anatomical route simulated by the student and the standard anatomical route planned by the doctor onto the surface of the specimen on the bed structure through the projection device. When teaching anatomy, the doctor uses the aforementioned auxiliary tool for medical anatomy to carry out the anatomical demonstration in conjunction with the route planning. The anatomical demonstration is carried out according to the standard anatomical teaching along the projected anatomical route, which is convenient for teaching and interpreting for students.
