Abstract
Description
Technical Field
[0001] This invention relates to the field of medical devices, specifically a device for removing pathological tissue from bone tumors with a cutting mechanism. Background Technology
[0002] Bone tumors are tumors that occur in the bones or their surrounding tissues. They can be benign or malignant. Benign bone tumors are easily cured and have a good prognosis, while malignant bone tumors develop rapidly, have a poor prognosis, and a high mortality rate. Before surgery, specimens from local tumor resection, after radical surgery, or from autopsy bone tissue specimens need to be sent to the pathology department for pathological diagnosis and reassessment. In these cases, the pathological specimens need to be dissected to obtain the necessary tissue samples with diagnostic value.
[0003] Currently, the bone tumor harvesting equipment used in our hospital is separate, consisting of a cleaver, axe, handsaw, and harvesting board. The problems with this equipment are as follows:
[0004] 1. When cutting bone tissue with machetes, axes and handsaws, bone fragments are easy to fly around, causing environmental pollution and being difficult to clean up. They also pose safety hazards. Flying bone fragments can cause splash injuries to medical staff. When cutting bone tissue for harvesting, the target bone tissue may fly outside the harvesting area, making it inconvenient to pick up.
[0005] 2. Because bones are hard, medical staff taking samples cannot accurately control the force, making it difficult to control the sample size. Summary of the Invention
[0006] The purpose of this invention is to provide a bone tumor pathological tissue extraction device with a cutting mechanism to solve the problems mentioned in the background art: 1. When cutting bone tissue with a machete, axe, or hand saw, bone fragments are easily scattered in all directions, causing environmental pollution and being difficult to clean up, and there are also safety hazards. The flying bone fragments can cause splash injuries to medical staff, and the target bone tissue may fly outside the sampling area during bone tissue sampling, making it inconvenient to pick up; 2. Due to the hardness of bone, medical staff taking samples cannot accurately control the force, making it difficult to control the sample size.
[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:
[0008] The present invention provides a bone tumor pathological tissue extraction device with a cutting device, comprising a box body, a protective box cover, a fixing component and a blade. The protective box cover is provided on the top of the box body and can move horizontally. An electromagnetic slide rail and an L-shaped support plate are fixedly installed in the middle of the upper end of the box body. A sliding plate that can move back and forth is provided at the upper end of the electromagnetic slide rail. A guide rail for horizontal movement of a guide block is fixedly installed at the upper end of the sliding plate. A fixing component is fixed at the upper end of the guide block. A fixing bolt for positioning is threaded to the front end of the guide block.
[0009] An electric lifting column is fixedly installed at the upper end of the L-shaped support plate. The telescopic end of the electric lifting column passes through the middle of the L-shaped support plate and is fixed to the housing. A drive motor is fixedly installed inside the housing. The output shaft of the drive motor is fixed to the connecting shaft for blade installation through a coupling.
[0010] The upper middle part of the slide plate has a groove that communicates with the internal cavity of the slide plate. Inside the groove, a barrier net is fixedly installed to prevent large pieces from clogging the telescopic tube. The mesh size of the barrier net is smaller than the size of the telescopic tube.
[0011] The front end of the enclosure is equipped with a control panel.
[0012] Preferably, the upper end of the housing is provided with moving grooves on both sides for the transmission rod to move laterally. Moving rails for the I-shaped block to move horizontally are fixedly installed on both sides above the moving grooves. The interior of the moving grooves is provided with bellows covers to prevent dust from falling into the housing. The upper end of the I-shaped block is fixedly connected to the crossbeam by screws, and the crossbeam is fixedly installed inside the protective housing cover.
[0013] Preferably, the bottoms of the two I-shaped blocks are fixedly connected to the top of the transmission rod, the sidewall of each transmission rod is fixedly connected to the telescopic end of the multi-stage electric push rod, and the multi-stage electric push rod is fixedly installed inside the housing.
[0014] Preferably, each fixing component includes a fixing ring, a support rod, an adjusting screw, a plug-in end, and a handle. The lower ends of both sides of the fixing ring are fixed with support rods, and the fixing ring is fixed to the guide block through the support rods. The wall of the fixing ring is triangular and has three screw holes for the adjusting screw to be screwed in. The end of each adjusting screw is threaded with a plug-in end that contacts the pathological specimen, and the end of each adjusting screw is fixedly installed with a handle for medical personnel to rotate the adjusting screw.
[0015] Preferably, the outer wall of the connecting shaft is provided with irregularly shaped locking blocks that are adapted to the locking slot at equal intervals, and the locking slot is opened in the middle of the blade. The end of the connecting shaft is threaded with a nut for fixing the blade, and the side wall of the nut abuts against the middle of the side wall of the blade. The side wall of the nut is bonded with an annular anti-slip pad to increase friction.
[0016] Preferably, one side of the slide plate is connected to a connector for connecting a telescopic tube. The lower end of the telescopic tube passes through the partition in the middle of the box and is fixed with a first connecting cap. The first connecting cap is threadedly connected to the feed port of the collection bag. The lower end of the collection bag is threadedly connected to a second connecting cap through the discharge port. A filter screen to prevent specimen debris from passing through is installed in the middle of the discharge port.
[0017] Preferably, the lower end of the second connecting cap is connected to the negative pressure end of the fan through a conduit, and the exhaust end of the fan extends to the side of the housing through an exhaust pipe.
[0018] Preferably, the front end of the protective cover has an embedding groove for installing a tempered glass plate, and the tempered glass plate is fixed to the embedding groove by screws, and rubber pads are adhered to the contact surfaces of the two protective covers.
[0019] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:
[0020] 1. This invention will use a protective box cover to protect medical personnel taking samples. While protecting medical personnel, the flying bone fragments will be blocked inside the protective box cover, which will facilitate the medical personnel to pick up the bone fragments later. In addition, since the box cover uses a tempered glass plate as an observation port, it will not affect the user's viewing of the sampling status of the device.
[0021] 2. This invention utilizes a fixing component to fix the sampled bone pathology specimen. Two fixing components can be adjusted according to the specimen size for fixation. When the pathology specimen is too short, only one fixing component is used to fix it, ensuring sufficient cutting point for the blade (i.e., the sampling range shown in the attached diagram). After the specimen is fixed, a drive motor rotates the blade, which, in conjunction with the electric lifting column, descends to complete the cutting of the pathology specimen. This structure avoids the problem of uneven bone fragments caused by uneven force when using axes, hand saws, or machetes. Attached Figure Description

[0037] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.
[0038] Please see Figure 1 - Figure 12 A bone tumor pathological tissue extraction device with a cutting device includes a box body 1, a protective box cover 2, a fixing component and a blade 12. The protective box cover 2, which can move horizontally, is provided on the top of the box body 1. An electromagnetic slide rail 3 and an L-shaped support plate 4 are fixedly installed in the middle of the upper end of the box body 1. A sliding plate 5, which can move back and forth, is provided on the upper end of the electromagnetic slide rail 3. A guide rail 7, which allows the guide block 6 to move horizontally, is fixedly installed on the upper end of the sliding plate 5. A fixing component is fixed on the upper end of the guide block 6. A fixing bolt 8 for positioning is threadedly connected to the front end of the guide block 6.
[0039] An electric lifting column 9 is fixedly installed at the upper end of the L-shaped support plate 4. The telescopic end of the electric lifting column 9 passes through the middle of the L-shaped support plate 4 and is fixed to the housing 10. A drive motor 11 is fixedly installed inside the housing 10. The output shaft of the drive motor 11 is fixed to the connecting shaft 13 for mounting the blade 12 through a coupling.
[0040] The upper middle part of the slide plate 5 has a groove 14 that communicates with the internal cavity of the slide plate 5. Inside the groove 14, a barrier net 16 is fixedly installed to prevent large pieces from clogging the telescopic tube 15. The mesh size of the barrier net 16 is smaller than the size of the telescopic tube 15.
[0041] The front of the housing 1 is equipped with a control panel 17. Considering that existing sampling methods mainly involve cutting bone tissue with machetes, axes, and hand saws, bone fragments are easily scattered, causing environmental pollution and being difficult to clean up, and also pose safety hazards. Scattered bone fragments can cause injuries to medical personnel. Furthermore, the target bone tissue may fly outside the sampling area during bone tissue cutting, making it inconvenient to retrieve. This device will use a protective housing 2 to protect the medical personnel during sampling. While protecting the medical personnel, the scattered bone fragments will be blocked inside the protective housing 2, facilitating subsequent retrieval by the medical personnel. Moreover, since the housing lid uses a tempered glass plate 43 as an observation port, it will not affect the user's view of the sampling status of the device. Considering that bone is relatively hard... The problem of medical staff being unable to accurately control the force during sampling, making it difficult to control the sample size, is addressed by this device. This device uses a fixing component to fix the sampled bone pathology specimen. Two fixing components can be adjusted to fix the specimen according to its size. When the pathology specimen is too short, only one fixing component will be used to fix the specimen, ensuring that the required cutting point of the blade 12 is reserved, i.e., the sampling range shown in the attached diagram of the instruction manual. After the specimen is fixed, the drive motor 11 will drive the blade 12 to rotate. The rotating blade 12, in conjunction with the electric lifting column 9, will descend, thus completing the cutting of the pathology specimen. The above structure avoids the situation of bone fragments flying due to uneven force when using axes, hand saws, and machetes.
[0042] Please refer to this carefully. Figure 1 , Figure 2 and Figure 5 As shown, considering the safety threat to medical personnel from bone fragments during sampling, the upper sides of the housing 1 are provided with moving grooves 19 for the transmission rod 18 to move laterally. Moving rails 21 for the I-shaped blocks 20 to move horizontally are fixedly installed on both sides above the moving grooves 19. The interior of the moving grooves 19 is provided with bellows covers 22 to prevent dust from falling into the housing 1. The upper end of the I-shaped blocks 20 is fixedly connected to the crossbeam 23 by screws, and the crossbeam 23 is fixedly installed inside the protective housing 2. This device uses the closed protective housing 2 to protect medical personnel. During sampling, the multi-stage electric push rod 24 drives the I-shaped blocks 20 at the upper end of the transmission rod 18 to move, thereby transmitting the power to the two protective housings 2 to close or open.
[0043] Please refer to this carefully. Figure 1 and Figure 5As shown, the bottom of the two I-shaped blocks 20 is fixedly connected to the top of the transmission rod 18. The side wall of each transmission rod 18 is fixedly connected to the telescopic end of the multi-stage electric push rod 24. The multi-stage electric push rod 24 is fixedly installed inside the housing 1. By setting the multi-stage electric push rod 24, the transmission rod 18 is driven. When the drive rod is driven by the multi-stage electric push rod 24, the drive rod will push the I-shaped block to move horizontally along the moving rail 21.
[0044] Please refer to this carefully. Figure 1 , Figure 3 , Figure 4 , Figure 8 and Figure 11 As shown, each fixing component includes a fixing ring 25, a support rod 26, an adjusting screw 27, a plug-in end 28, and a handle 29. Support rods 26 are fixed to the lower ends of both sides of the fixing ring 25, and the fixing ring 25 is fixed to the guide block 6 via the support rods 26. The wall of the fixing ring 25 is triangular with three screw holes for the adjusting screw 27 to be screwed into. Each adjusting screw 27 has a threaded connection at its end to a plug-in end 28 that contacts the pathological specimen. A handle 29 is fixedly installed at the end of each adjusting screw 27 for medical personnel to rotate. The fixation components effectively secure orthopedic pathological samples. Two or one fixation components can be installed as needed. When using two fixation components, the distance between them is adjusted using guide block 6 to accommodate pathological samples of different lengths. During fixation, simply place the specimen in the middle of the fixation ring 25 and abut it against the lower insertion end 28. Then, fix the upper two insertion ends 28 by tightening the adjusting screw 27. Once the three insertion ends 28 abut against the pathological specimen, the specimen will be positioned.
[0045] Please refer to this carefully. Figure 1 , Figure 3 , Figure 4 , Figure 8 , Figure 9 and Figure 10 As shown, the outer wall of the connecting shaft 13 is evenly distributed with irregularly shaped locking blocks 30 that are adapted to the locking groove 31, and the locking groove 31 is opened in the middle of the blade 12. The end of the connecting shaft 13 is threaded with a nut 32 for fixing the blade 12, and the side wall of the nut 32 abuts against the middle of the side wall of the blade 12. An annular anti-slip pad 33 to increase friction is glued to the side wall of the nut 32. By setting the connecting shaft 13 and the blade 12 to use irregularly shaped locking blocks 30 to cooperate with the locking groove 31 for installation, and then using the nut 32 for reinforcement, it is convenient for the sampling personnel to disassemble and replace the worn blade 12 later. In order to increase the fixing effect of the nut 32, a protective annular anti-slip pad 33 is glued to the contact surface between the nut 32 and the blade 12.
[0046] Please refer to this carefully. Figure 1, Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, one side of the slide plate 5 is connected to a connector 34 for the telescopic tube 15 to be connected. The lower end of the telescopic tube 15 passes through the partition in the middle of the box 1 and is fixed with the first connecting cap 35. The first connecting cap 35 is threadedly connected to the feed port 36 of the collection bag 44. The lower end of the collection bag 44 is threadedly connected to the second connecting cap 38 through the discharge port 37. A filter screen 39 is installed in the middle of the discharge port 37 to prevent specimen debris from passing through. By setting up the trough 14, the collection bag 44, the telescopic tube 15 and the fan 41, the debris falling on the slide plate 5 is collected. When collecting, the fan 41 works and the negative pressure end generates negative pressure, which causes the debris in the process of the blade 12 cutting the pathological specimen to be attracted into the inside of the collection bag by the negative pressure.
[0047] Please refer to section 1 and 2. Figure 7 As shown, the lower end of the second connecting cap 38 is connected to the negative pressure end of the fan 41 through the conduit 40, and the exhaust end of the fan 41 extends to the side of the housing 1 through the exhaust pipe 42.
[0048] Please refer to this carefully. Figure 1 and Figure 2 As shown, the front end of the protective cover 2 is provided with an embedding groove for installing the tempered glass plate 43, and the tempered glass plate 43 is fixed to the embedding groove by screws. Rubber pads are glued to the contact surfaces of the two protective covers 2. By setting the tempered glass plate 43, it is convenient for the sampling personnel to observe the sampling process through the protective cover 2.
[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
