Description

Technical Field

[0001] The present invention relates to the technical field of forensic science, and in particular to a portable auxiliary device for three-dimensional scanning imaging of a corpse's oral cavity. Background Art

[0002] Teeth are the hardest tissue in the human body, maintaining their morphological structure long after death, making them crucial for identifying unidentified bodies. However, existing imaging methods have limitations: digital cameras and X-ray imaging can only capture 2D projection images, recording limited tooth morphological features and prone to morphological distortion due to the shooting angle, hindering feature comparison. While CT 3D reconstruction can reveal the spatial morphology of teeth, it is time-consuming, costly, and emits radiation, making it difficult to scale. Therefore, a faster and more convenient 3D oral scanning imaging method is needed to improve the efficiency and accuracy of tooth identification.

[0003] However, due to rigor mortis, the jaw joint of the corpse is stiff, the upper and lower teeth cannot open and close normally, and the head and oral posture cannot be adjusted, which makes 3D scanning of the oral cavity difficult. This requires the development of a portable auxiliary device suitable for three-dimensional scanning and imaging of the oral cavity of a corpse, so that forensic doctors can quickly collect 3D dental images at the crime scene at the first time.

[0004] For example, the patent number CN109431441B for "an easily adjustable oral lip stretching device" can adjust the lip stretching width by adjusting the extension length of the telescopic rod and fix it with a fixing bolt, but it does not effectively fix the head. In addition, when the upper and lower teeth of the corpse in the rigor mortis state cannot open and close normally, it is inconvenient to use. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a portable auxiliary device for three-dimensional scanning imaging of the cadaver oral cavity.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A portable auxiliary device for three-dimensional scanning and imaging of a cadaver's oral cavity comprises a base, a first support plate, and a second support plate. The first support plate is provided with a clamping assembly for securing the cadaver's head and massaging the cheeks. The second support plate is provided with a prying assembly for prying open the cadaver's upper and lower dentition. The second support plate is also provided with an opening assembly for opening the cadaver's cheeks. The pry assembly consists of a rotating part, a sliding part, and a pry part. The sliding part is provided with a first guide rod, and the pry part is provided with a pivot and a pry arm. The rotating part is threadedly connected to the sliding part. When the rotating part rotates, the sliding part is driven to slide on the first guide rod. When the sliding part slides downward, it pushes the two pry arms to rotate around the pivot and spread outward.

[0007] Preferably, the clamping assembly consists of a clamping part, a liquid pumping part, and a massage part. The massage part is fixedly connected to the clamping part, and the clamping part slides on the first bracket plate. When the clamping part slides, the massage part is driven to slide synchronously, and the liquid pumping part synchronously pumps liquid into the clamping part and the massage part.

[0008] Preferably, a telescopic water bag, a first solenoid valve and a second solenoid valve are provided in the massage part, and the telescopic water bag is intermittently telescoped and expanded synchronously by the intermittent opening and closing of the first solenoid valve and the second solenoid valve.

[0009] Preferably, the opening assembly consists of a synchronization part and an opening part. The synchronization part and the rotating part are rotationally connected through a first bevel gear. When the rotating part rotates, the synchronization part is driven to rotate synchronously through the first bevel gear. A gear is provided in the synchronization part and a rack is provided in the opening part. The synchronization part and the opening part are transmitted through the meshing of the gear and the rack.

[0010] Preferably, a support assembly is provided on the base, and the support assembly is used to support the head and neck of the corpse.

[0011] Preferably, a lifting assembly is provided on the second bracket plate, a transmission box is provided in the lifting assembly, the pry assembly and the opening assembly are arranged in the transmission box, and the pry assembly and the opening assembly slide as the transmission box rises and falls.

[0012] Preferably, a second liquid outlet pipe is provided in the liquid pump part, and a liquid outlet branch pipe and a flow pipe are provided in the massage part. One end of the liquid outlet branch pipe is fixedly connected to the second liquid outlet pipe, and the other end is fixedly connected to the flow pipe. The first solenoid valve is fixedly connected to the liquid outlet branch pipe. When the second liquid outlet pipe discharges liquid, part of the liquid enters the flow pipe when the first solenoid valve is intermittently opened, and the other part of the liquid enters the water bag through the outlet at the other end of the second liquid outlet pipe.

[0013] Preferably, a second electric push rod is provided on the side wall of the transmission box, a fixed seat is provided in the transmission box, the prying part is rotatably set on the fixed seat, the sliding part is slidably set on the fixed seat, and the telescopic end of the second electric push rod is fixedly connected to the fixed seat.

[0014] Preferably, a first sliding groove is provided on the first bracket plate, and a second sliding groove is provided on the second bracket plate.

[0015] The present invention has the following beneficial effects: 1. In the present invention, when it is necessary to perform three-dimensional imaging of the oral cavity of a corpse, the head and neck of the corpse can be placed on a support pad and adjusted to a suitable position by the first electric push rod. The clamping part slides, driving the massage part to slide synchronously to clamp the cheek part of the corpse. The pumping part synchronously pumps warm water in the constant temperature water tank into the clamping part and the massage part. The telescopic water bag is intermittently expanded and contracted by the intermittent opening and closing of the first solenoid valve and the second solenoid valve, so as to massage and relax the cheek muscles of the corpse and relieve the stiffness of the cheek muscles.

[0016] 2. Furthermore, the tooth pry assembly and the opening assembly slide down as the transmission box descends, and the second electric push rod pushes the fixed seat down, while driving the pry arm to slide downward. The staff can put the opener into the cheeks on both sides of the corpse and align the pry arm with the gap between the corpse's teeth. At this time, the motor starts to drive the rotating part to rotate, and drives the sliding part to slide on the first guide rod. When the sliding part slides downward, it pushes the two pry arms to rotate around the pivot and spread them outward, thereby prying open the upper and lower teeth of the corpse's mouth.

[0017] 3. Synchronously, when the rotating part rotates, the synchronizing part is driven to rotate synchronously through the first bevel gear. The synchronizing part and the opening part are transmitted through the engagement of the gear and the rack, thereby driving the opening part to slide. When the opening part slides, the opener inside it pulls the cheeks of the corpse to both sides, exposing the inside of the corpse's mouth to facilitate subsequent three-dimensional scanning and imaging of the teeth.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1:

[0021] Reference Figure 1-Figure 5 and Figure 9 、 Figure 10 A portable auxiliary device for three-dimensional scanning and imaging of the oral cavity of a corpse includes a base 1, a first bracket plate 2, and a second bracket plate 3.

When the clamping part slides, the massage part is driven to slide synchronously, and the liquid pumping part synchronously pumps liquid into the clamping part and the massage part.

[0023] The massage part is provided with a telescopic water bag 7, a first electromagnetic valve 18, and a second electromagnetic valve 19.

One end of the liquid outlet branch pipe 14 is fixedly connected to the second liquid outlet pipe 13, and the other end is fixedly connected to the flow pipe 15. The first solenoid valve 18 is fixedly connected to the liquid outlet branch pipe 14. When the second liquid outlet pipe 13 discharges liquid, part of the liquid enters the flow pipe 15 when the first solenoid valve 18 is intermittently opened, and the other part of the liquid enters the water bag 6 through the outlet at the other end of the second liquid outlet pipe 13.

[0026] The first bracket plate 2 is provided with a first sliding groove 8 , and the second bracket plate 3 is provided with a second sliding groove 23 .

[0027] In this embodiment, the clamping assembly is composed of a clamping part, a liquid pumping part, and a massage part. The clamping part, the liquid pumping part, and the massage part can specifically adopt the following structures: The clamping part consists of a first cylinder 4, a splint 5, a water bag 6, and a first slider 9. The first slider 9 slides in the first slide groove 8. The first slider 9 is fixedly connected to the splint 5. The side wall of the splint 5 is fixedly connected to the water bag 6. The first cylinder 4 is fixedly connected to the other side wall of the splint 5.

[0028] The pump liquid part consists of a constant temperature water tank 10, a first liquid outlet pipe 11, a water pump 12, a second liquid outlet pipe 13, a liquid outlet branch pipe 14, and a liquid inlet pipe 17. The constant temperature water tank 10 and the water pump 12 are arranged on the base 1. One end of the first liquid outlet pipe 11 is connected to the water outlet of the constant temperature water tank 10, and one end is connected to the water inlet of the water pump 12. One end of the second liquid outlet pipe 13 is connected to the water outlet of the water pump 12, and the other end passes through the splint 5 and is fixedly connected to the water bag 6. One end of the liquid inlet pipe 17 passes through the splint 5 and is connected to the water bag 6, and the other end is connected to the water inlet of the constant temperature water tank 10. One end of the liquid outlet branch pipe 14 is fixedly connected to the second liquid outlet pipe 13.

[0029] The massage part consists of a flow tube 15, a flow branch tube 16, a telescopic water bag 7, a first solenoid valve 18, and a second solenoid valve 19. The other end of the liquid outlet branch tube 14 is fixedly connected to one end of the flow tube 15, and the other end is fixedly connected to the liquid inlet tube 17. Several telescopic water bags 7 are arranged on the water bag 6, and several flow branch tubes 16 are arranged on the flow tube 15. The flow branch tubes 16 are respectively fixedly connected to the corresponding telescopic water bags 7.

[0030] The supporting component may specifically adopt the following structure: The support assembly consists of a first electric push rod 20 and a support pad 21 . The first electric push rod 20 is arranged on the base 1 , and the telescopic end of the first electric push rod 20 is fixedly connected to the lower end of the support pad 21 .

[0031] In this embodiment, when three-dimensional imaging of the oral cavity of a corpse is required, the head and neck of the corpse can be placed on the support pad 21 and adjusted to a suitable position by the first electric push rod 20 to support the head and neck of the corpse. Then the first cylinder 4 pushes the splint 5 and the water bag 6 to slide to clamp the cheeks on both sides of the corpse. Synchronously, the water pump starts to pump out the warm water in the constant temperature water tank 10. When the second liquid outlet pipe 13 discharges liquid, a part of the liquid enters the flow tube 15 when the first solenoid valve 18 is intermittently opened, and the other part of the liquid enters the water bag 6 through the outlet at the other end of the second liquid outlet pipe 13. The water bag 6 expands with water and flexibly clamps the two sides of the corpse's cheeks. At the same time, warm water is applied to relieve the stiffness of the corpse's cheek muscles.

[0032] Furthermore, the liquid entering the flow tube 15 enters the telescopic water bag 7 through the flow branch 16 to drive its expansion, and the telescopic water bag 7 can be intermittently expanded and contracted synchronously through the intermittent opening and closing of the first solenoid valve 18 and the second solenoid valve 19 to perform flexible squeezing and massage on both sides of the corpse's cheeks, further relieving the stiffness of the cheek muscles.

[0033] It should be noted that the warm water entering the water bag 6 can flow back to the constant temperature water tank 10 through the liquid inlet pipe 17. At the same time, when the second solenoid valve 19 is intermittently opened, the liquid in the telescopic water bag 7 flows back to the constant temperature water tank 10 together with the liquid in the water bag 6, thereby realizing the circulation of the liquid in the water bag 6 and the telescopic water bag 7.

The second electric push rod 28 pushes the fixed seat 29 to slide down, and at the same time drives the pry arm 31 to slide downward. The staff can align the pry arm 31 with the gap between the corpse's molars. At this time, the motor 26 starts and drives the threaded rod 27 to rotate. The threaded cylinder 32 slides downward under the limiting action of the first guide rod 33 and pushes the upper end of the pry arm 31. The two pry arms 31 rotate around the pivot 30 and spread outward to pry open the upper and lower teeth of the corpse's mouth. Example 3:
