[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 2 This utility model provides a cartilage sample collection device, including a fixed base plate 16, a movable base plate 9 slidably connected to the upper limit of the fixed base plate 16, an installation plate 15 detachably mounted on the top of the movable base plate 9 along the vertical direction, the installation plate 15 being located in the middle of the movable base plate 9, a cutting mechanism mounted on the installation plate 15, the cutting mechanism being used to cut and shape the cartilage sample, a plurality of pads 22 being detachably mounted on the cutting mechanism, the pads 22 being used to adjust the thickness of the cut cartilage sample, a power supply 20 and a driver 21 being detachably mounted inside the cartilage sample collection device, the power supply 20 being used to supply power to the electrical appliances inside the cartilage sample collection device, and the driver 21 being communicatively connected to the cutting mechanism.

[0033] In this embodiment, during use, the power supply 20 is first connected to an external power socket to supply power to the electrical appliances in the entire device. Those skilled in the art will understand that the power supply 20 can also be any component capable of providing power, such as a portable power bank, which is known in the art and will not be elaborated upon here. Then, according to the actual length of the cartilage sample, the movable base plate 9 on the fixed base plate 16 is slid to adjust its position and adapt to the length of the cartilage sample. After adaptation, the number of pads 22 is increased or decreased according to the required cutting thickness. After adjustment, the cartilage sample is placed above the movable base plate 9, and the cutting mechanism is controlled by the signal from the driver 21. The cutting mechanism cuts and shapes the cartilage sample placed above the movable base plate 9, thereby completing the sample collection process.

[0034] Further optimize the plan, referring to Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The cutting mechanism includes a blade holder 4 that is vertically limited and slidably mounted on the side wall of the mounting plate 15. A first electric telescopic rod 17 is provided on the side of the mounting plate 15 away from the blade holder 4. The driver 21 is communicatively connected to the first electric telescopic rod 17 to control the first electric telescopic rod 17. The power supply 20 can supply power to the first electric telescopic rod. The bottom end of the first electric telescopic rod 17 is detachably connected to the movable base plate 9. The telescopic end of the first electric telescopic rod 17 is detachably connected to the top end of the blade holder 4. A cutting blade 3 is detachably mounted on the bottom end of the blade holder 4. The cutting blade 3 is set with its blade head facing downward. A pad 22 is detachably mounted between the cutting blade 3 and the blade holder 4. The thickness of the pad 22 is 1mm. The cutting blade 3 is used to cut cartilage bone samples. A cutting groove 5 is detachably mounted on the top end of the movable base plate 9. The cutting groove 5 is located below the blade holder 4 and is set corresponding to the blade holder 4. A cutting hole 6 is opened on the side wall of the cutting groove 5 away from the mounting plate 15. The cutting hole 6 has a circular structure and is connected to the interior of the cutting groove 5.

[0035] In this embodiment, refer to Figure 5 The tool holder 4 has a mounting groove on one side wall for mounting the pad 22 and the cutting blade 3. Three threaded holes arranged in a triangle are pre-drilled in the mounting groove. (Refer to...) Figure 6 The pad 22 is adapted to the shape of the mounting groove and also has three threaded holes corresponding to the threaded holes in the mounting groove, see reference. Figure 8The shape of the cutting blade 3 is also compatible with the mounting groove, and it is also provided with three threaded holes that correspond to the threaded holes in the mounting groove. Therefore, the pad 22 and the cutting blade 3 can be installed in the mounting groove of the tool holder 4 by bolts. The triangle shape is stable, which can further ensure the firmness of the installation and prevent it from falling off.

[0036] When installing the cutting blade 3 on the tool holder 4, according to the actual cutting needs, first install the required number of pads 22 in the mounting slot of the tool holder 4, then install the cutting blade 3 on the pads 22, and finally fix them with bolts to form a sandwich structure with the pads 22 in the middle and the cutting blade 3 and the tool holder 4 on both sides. At the same time, the number of pads 22 can be increased or decreased according to the actual cutting needs, thereby adjusting the cutting position of the cutting blade 3.

[0037] In this embodiment, refer to Figure 10 The inner wall of the cutting groove 5, away from the cutting hole 6, is provided with a slicing groove. The bottom of the slicing groove is an arc structure corresponding to the cutting hole 6, and the transverse groove depth of the slicing groove along the direction of the cutting hole 6 is 1mm. When installing the cutting blade 3, if the spacer 22 is not installed between it and the cutting blade 3 is directly installed on the blade holder 4, the side wall of the cutting blade 3 will be tangent to the outer wall of the slicing groove near the cutting hole 6. In other words, if it is necessary to cut a bone sample section with a thickness of 1mm, the forensic doctor can directly install the cutting blade 3 on the blade holder 4 without installing a spacer 22 between it and the cutting hole 6. Pad 22; In use, the forensic doctor can insert the cartilage sample to be cut into the cutting groove 5 through the cutting hole 6, and place the cartilage sample in the slicing groove. Then, the driver 21 controls the first electric telescopic rod 17 to lower it. The first electric telescopic rod 17 will drive the knife holder 4 and the cutting blade 3 to lower simultaneously, thereby inserting the cutting blade 3 into the cutting groove 5 to cut the cartilage sample inside. After the cutting is completed, the first electric telescopic rod 17 is used to raise the cutting blade 3, thereby removing the cut bone sample slice from the cutting groove 5.

[0038] If a 2mm thick cartilage bone sample section needs to be cut, a pad 22 can be installed on the blade holder 4, and then the cutting blade 3 can be installed. At this time, the position of the cutting blade 3 will be shifted 1mm towards the cutting hole 6 compared to when the pad 22 is not installed. In this way, a 2mm thick cartilage bone sample section can be cut. Similarly, if a 3mm thick cartilage bone sample section needs to be cut, two pads 22 can be installed on the blade holder 4.

[0039] In a further optimized design, the cutting mechanism also includes a connecting rod 7 vertically positioned above the movable base plate 9. The connecting rod 7 is located on the side of the blade holder 4 furthest from the mounting plate 15. In this embodiment, referring to... Figure 2The connecting rod 7 is detachably connected to the tool holder 4 via a vertically installed bolt, and a spring is fitted onto this bolt. The spring force better ensures the connection stability between the connecting rod 7 and the tool holder 4. Two locking rods are symmetrically arranged at the top of the connecting rod 7. In this embodiment, refer to... Figure 5 When installed on the tool holder 4, the connecting rod 7 is installed on the crossbeam at the upper end of the tool holder 4, and the two locking rods are respectively passed through the two locking holes pre-drilled on the crossbeam. This can limit the connecting rod 7, prevent the connecting rod 7 from rotating, and further ensure the connection stability between the connecting rod 7 and the tool holder 4.

[0040] A cutting blade 8 is detachably mounted at the bottom end of the connecting rod 7. In this embodiment, refer to... Figure 4 The detachable connection method between the cutter 8 and the connecting rod 7 is not limited, but a bolted detachable connection method is preferred. The cutter 8 is used to cut the shape of the cartilage sample.

[0041] In this embodiment, the cutting blade 8 is rectangular in shape, so the cartilage sample can be cut into a rectangle. At the same time, the forensic doctor can also replace the cutting blade 8 with different shapes at the bottom of the connecting rod 7 according to the actual cutting needs, such as circular or triangular cutting blades 8, so as to cut cartilage samples of different shapes.

[0042] When in use, the forensic doctor can place the cartilage sample to be cut under the cutting blade 8, and then activate the first electric telescopic rod 17 to lower its telescopic end, thereby driving the blade holder 4, connecting rod 7 and cutting blade 8 to descend simultaneously, thereby cutting the cartilage sample.

[0043] Furthermore, since the cutting blade 8 and the cutting blade 3 are detachably connected to the blade holder 4, the forensic doctor can not only perform individual cutting and trimming of cartilage samples, but also perform both simultaneously. For example, a cartilage sample to be cut can be placed separately in the cutting groove 5, and another cartilage sample to be trimmed can be placed separately under the cutting blade 8. Then, the first electric telescopic rod 17 can be activated to lower the blade holder 4, thereby enabling the simultaneous cutting and trimming of cartilage samples, further improving work efficiency.

[0044] Further optimize the plan, referring to Figure 2 A second slide rail 13 is detachably installed on the side wall of the mounting plate 15 in the vertical direction. A second slider corresponding to the second slide rail 13 is detachably installed on the tool holder 4. The tool holder 4 is limited and slidably connected to the mounting plate 15 through the second slide rail 13 and the second slider.

[0045] In this embodiment, refer to Figure 2There are two second slide rails 13, which are symmetrically arranged on the side wall of the mounting plate 15. There are four second sliders, which are installed in pairs on both sides of the tool holder 4. The two sets of second sliders are slidably engaged with the two second slide rails 13 respectively.

[0046] Further optimize the plan, referring to Figure 2 and Figure 11 The top of the movable base plate 9 is detachably equipped with a bone cutting support plate 10. The top of the bone cutting support plate 10 is preferably an arc-shaped structure, and the arc-shaped structure is tangent to the cutting hole 6. The bone cutting support plate 10 abuts against the side wall of the cutting groove 5 away from the mounting plate 15.

[0047] The arc-shaped structure above the bone cutting plate 10 can be used to place the cartilage sample. When cutting the cartilage sample, the arc-shaped structure above the bone cutting plate 10 can make the cartilage sample more stable during cutting, thus ensuring the smooth progress of the work.

[0048] Further optimize the plan, referring to Figure 2 A cutting table 11 is detachably mounted on the bone cutting support plate 10. Preferably, the bone cutting support plate 10 and the cutting table 11 are detachably connected by bolts, and the cutting table 11 is located directly below the cutting knife 8.

[0049] When cutting cartilage samples, the cartilage samples to be cut can be placed on the cutting table 11. Since the cutting table 11 is mounted on the bone cutting support plate 10, the cutting and cutting of cartilage samples can be divided into the following situations:

[0050] (1) When the cartilage sample to be cut is long, the cutting table 11 installed on the bone cutting plate 10 is removed, so that the long cartilage sample can be placed on the bone cutting plate 10, but at this time only the cartilage sample can be cut.

[0051] (2) When the cartilage sample to be cut is short, if its length is shorter than the distance between the cutting table 11 and the cutting groove 5, then the cutting table 11 can be removed and the cartilage sample can be cut directly. At this time, the cartilage sample to be cut can also be cut at the same time.

[0052] In addition, the cutting table 11 can hold cartilage bone sample slices cut by the cutting blade 3 for cutting, or it can hold cartilage bone sample slices cut by the non-cutting blade 3, or it can directly cut the cartilage bone sample without slices according to actual needs. The specific method is not particularly limited here.

[0053] Further optimize the plan, referring to Figure 2 and Figure 3The top of the fixed base plate 16 is provided with a sliding groove along the horizontal direction. A first slide rail 12 is detachably installed in the sliding groove. A first slider corresponding to the first slide rail 12 is detachably installed on the movable base plate 9. The movable base plate 9 is limited and slidably connected to the fixed base plate 16 through the first slider and the first slide rail 12.

[0054] In this embodiment, there are two first slide rails 12, which are symmetrically arranged at the top of the fixed base plate 16. Therefore, there are also two sliding grooves. There are four first sliders, which are arranged in pairs at the bottom of the movable base plate 9. The two sets of first sliders slide in cooperation with the two first slide rails 12 respectively.

[0055] Further optimize the plan, referring to Figure 2 and Figure 3 A second electric telescopic rod 18 is provided above the fixed base plate 16. One end of the second electric telescopic rod 18 is detachably connected to the fixed base plate 16. The second electric telescopic rod 18 is arranged parallel to the first slide rail 12. The other end of the second electric telescopic rod 18 is detachably connected to the movable base plate 9 or the mounting plate 15. The second electric telescopic rod 18 is communicatively connected to the driver 21 to realize the control of the second electric telescopic rod 18. The second electric telescopic rod 18 is electrically connected to the power supply 20, which can provide power to the second electric telescopic rod 18.

[0056] In this embodiment, there are two second electric telescopic rods 18, which are arranged symmetrically above the fixed base plate 16 and are arranged in sequence to correspond to the two first slide rails 12.

[0057] When the movable base plate 9 needs to be moved, the forensic doctor can control the second electric telescopic rod 18 to extend or retract through the driver 21. This allows the position of the movable base plate 9 to be automatically adjusted according to actual needs, saving the cost of manually adjusting the position of the movable base plate 9 and improving convenience.

[0058] In this utility model, the driver 21 controls the first electric telescopic rod 17 and the second electric telescopic rod 18 using PLC automatic control technology. PLC automatic control technology is existing technology known to those skilled in the art, so it will not be described in detail.

[0059] Further optimize the plan, referring to Figure 1 A housing 1 is detachably mounted on the fixed base plate 16. In this embodiment, the housing 1 can be an inverted L-shaped structure. The housing 1 can be used to protect the internal components of the cartilage bone sample collection device. A shelf 19 is detachably mounted horizontally above the mounting plate 15. (Refer to...) Figure 3The shelf 19 has a horizontal L-shaped structure. The shelf 19 is detachably connected to the inner wall of the outer shell 1 by bolts. The power supply 20 is detachably installed on the top of the shelf 19. The driver 21 is detachably installed on the vertical plate at the bend of the shelf 19. There are two drivers 21. The two drivers 21 are used to control the first electric telescopic rod 17 and the second electric telescopic rod 18, respectively. Both drivers 21 are located on the side of the shelf 19 away from the mounting plate 15. The drivers 21 and the power supply 20 are located inside the outer shell 1. The inner walls at both ends of the outer shell 1 are clearance-fitted with the side walls of the movable base plate 9 and the side walls of the mounting plate 15. The clearance can be 1mm-3mm.

[0060] In this utility model, reference is made to Figure 2 When the movable base plate 9 moves to the maximum position to the left, that is, when the first slider on the left is about to disengage from the first slide rail 12, the second electric telescopic rod 18 will stop extending. At this time, the position of the mounting plate 15 will be exactly tangent to the outer wall of the opening of the outer shell 1, and the top of the mounting plate 15 will be exactly at the leftmost position of the horizontal plate of the layer plate 19. Since the inner side walls at both ends of the outer shell 1 are clearance-fitted with the side walls of the movable base plate 9 and the side walls of the mounting plate 15, and the layer plate 19 is provided above the mounting plate 15, the layer plate 19 and the outer shell 1 can effectively block the soft tissue and other substances that are splashed during the cutting of the cartilage sample, preventing them from contaminating the internal components of the outer shell 1.

[0061] Among them, reference Figure 2 A distance sensor is installed on the top of the side wall of the mounting plate 15 away from the tool holder 4, and the distance sensor is communicatively connected to the driver 21. When the mounting plate 15 moves toward the inside of the housing 1, the distance sensor can monitor the distance between the mounting plate 15 and the vertical plate at the bend of the shelf 19 in real time. If the distance is too close, a signal will be transmitted to the driver 21, and the second electric telescopic rod 18 will stop working. This can prevent the components inside the device from being damaged under the tension of the second electric telescopic rod 18. The distance sensor is prior art known to those skilled in the art, and will not be described in detail here.

[0062] In a further optimized design, a baffle 2 is detachably installed on the side wall of the fixed base plate 16 along the vertical direction. The baffle 2 is located on the side of the mounting plate 15 near the knife holder 4 and is set parallel to the mounting plate 15. The baffle 2 can block soft tissue and other substances that splash in the horizontal direction, preventing them from polluting the external environment.

[0063] In a further optimized design, the cartilage sample collection device is equipped with a reset switch 14, which is communicatively connected to the driver 21, the first electric telescopic rod 17, and the second electric telescopic rod 18. In this embodiment, refer to... Figure 1The reset switch 14 is mounted on the housing 1, but it can also be mounted in other places that are easy for forensic personnel to touch. When it is necessary to reset the first electric telescopic rod 17 and the second electric telescopic rod 18, the reset switch 14 is pressed. The reset switch 14 will send a signal to the driver 21, and the driver 21 will then send a signal to control the first electric telescopic rod 17 and the second electric telescopic rod 18, and reset the first electric telescopic rod 17 and the second electric telescopic rod 18, providing better convenience for forensic personnel.

[0064] In this invention, the preferred method of detachable connection is bolt connection. However, those skilled in the art can also choose other detachable connection methods besides bolt connection according to the actual situation.
