Description

Technical Field

[0001] This invention relates to the field of medical assistive devices, specifically an adjustable fixator for taking bone tumor pathological specimens. Background Technology

[0002] Bone tumors are tumors that occur in bones or their surrounding tissues. Bone tumors can be benign or malignant. Benign bone tumors are easy to cure and have a good prognosis, while malignant bone tumors develop rapidly, have a poor prognosis, and a high mortality rate. Pathological reports for bone tumors are obtained from bone tumor specimens, so it is necessary to take specimens from the patient's bones.

[0003] Because bone tumor specimens contain bone tissue, which is hard and often irregular in shape, it is necessary to firmly fix the bone tissue specimen to be sampled for easy sampling.

[0004] Currently, our hospital's pathology department does not have a corresponding fixation device when collecting bone tumor samples; they are all fixed by hand. This causes many problems during the sampling process and can easily lead to injuries to medical staff. For example, when cutting bone tumor specimens, the manual fixation is not secure, and the specimens are prone to slipping from the hands, causing danger. Secondly, when encountering irregular bone tumor specimens, the lack of secure fixation makes it difficult for medical staff to control the sampling position and size. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable fixator for bone tumor pathological specimen collection, in order to solve the many problems mentioned in the background art that exist in the collection process, which can easily lead to injuries to medical staff. For example, when cutting and collecting bone tumor specimens, manual fixation is not secure enough, and the specimens are easy to slip from the hands, causing danger. Secondly, when encountering irregular bone tumor specimens, the lack of secure fixation makes it difficult for medical staff to control the location and size of the specimen.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] The present invention provides an adjustable fixation device for bone tumor pathological specimen collection, comprising a base, a lifting seat, an inclined seat, a positioning ring and a fixing component. The base is used to fix the device to the operating table. Columns are fixedly installed on both sides of the upper end of the base. Lifting seats that can be raised and lowered longitudinally are provided above the columns on both sides. The opposite surfaces of the two lifting seats are rotatably connected to the same inclined seat through a slewing bearing.

[0008] The upper ends of both sides of the inclined seat are fixedly installed with two pillars by angle brackets. The top of each pillar is rotatably connected with a guide wheel for abutting the guide groove, and the guide groove is opened on the front and rear surfaces of the positioning ring.

[0009] The inner wall of the positioning ring is integrally formed with multiple docking blocks for mounting the front and rear annular shells. The surfaces of the front and rear annular shells are integrally formed with slide rails for mounting the sliders. The side walls of the front and rear annular shells are provided with grooves that are adapted to the docking blocks. The front and rear annular shells are fixed to the docking blocks by fixing bolts and nuts.

[0010] Each slider has a fixed mounting component at its upper end for securing pathological specimens.

[0011] Preferably, the base has clamps on both sides below it, and the upper surfaces of the two clamps are rotatably connected to the mounting bolts via bearings on the front and rear sides. Multiple mounting bolts are threaded into the base.

[0012] Preferably, an electric lifting column is installed inside one of the columns, and the telescopic end of the electric lifting column is fixedly connected to one of the lifting seats. Guide bars adapted to the guide rail are fixedly installed on both sides of the bottom of the two lifting seats, and the guide rail is fixedly installed on the side of the column.

[0013] Preferably, one of the lifting seats has a cavity inside for mounting a first self-locking motor. The output shaft of the first self-locking motor passes through the side of the lifting seat and is fixed to the detection shaft of the rotation angle sensor. The rotation angle sensor is fixed to the side of the lifting seat by an L-shaped plate, and the rotation angle sensor is connected to the control panel circuit on one side of the column. The control panel is also connected to the motor driver circuit inside the cavity by a wire.

[0014] Preferably, the output shaft of the first self-locking motor is fixedly sleeved with a drive gear, and the upper end of the drive gear is meshed with a driven gear, the driven gear being fixedly installed outside the rotating end of a slewing bearing on one side.

[0015] Preferably, a second self-locking motor is installed in the middle of the tilting seat through a housing, and a drive gear is fixed outside the output shaft of the second self-locking motor, and the drive gear is engaged with the locking teeth outside the positioning ring.

[0016] Preferably, each of the plurality of fixing components includes a mounting sleeve, a pen-type electric actuator, a connector, and a tip sleeve. The mounting sleeve has an internal cavity for mounting the pen-type electric actuator. The telescopic end of the pen-type electric actuator passes through the top of the mounting sleeve and is fixedly connected to the connector. The connector is covered with a tip sleeve.

[0017] Preferably, a pressure sensor is installed on the top of the plug sleeve, and the upper surface of the pressure sensor abuts against the inner surface of the tip sleeve. The left and right sides of the tip sleeve are provided with strip grooves for installing the limit bolts, and the bottom of the limit bolts is threaded into the screw holes opened on both sides of the plug.

[0018] Preferably, the slide rail has an annular external shape and a mounting notch for mounting a slider at the middle end. The slider is fixed to the slide rail by a positioning bolt connected to the front end by a threaded connection.

[0019] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0020] 1. When cutting and collecting bone tumor specimens, manual fixation is not secure and the specimens are prone to slipping from the hands, which may cause danger. This device uses multiple fixation components to fix the pathological specimen in the middle of the positioning ring, which is safer than manual fixation. At the same time, when sampling, the angle of entry can be adjusted by rotating the tilting seat.

[0021] 2. When encountering irregular bone tumor specimens, the lack of secure fixation makes it difficult for medical staff to control the sampling location and size. As needed, a number of fixation components will be installed into the positioning ring. By increasing the fixation points for the pathological specimen, the stability of the device on the pathological surface will be increased. Considering the irregularity of the pathological surface, a pointed sleeve will be inserted into the pathological specimen to complete the fixation, further enhancing the stability. In addition, the extension and retraction length of the pointed sleeve can be controlled by the telescopic end of the pen-type electric push rod according to the size of the pathological specimen.

[0022] 3. This device will use the first self-locking motor to drive the tilting seat to complete the tilting of the front and back angles, so that the fixed pathological specimen can be rotated to a suitable sampling angle. At the same time, in order to ensure the accuracy of the angle adjustment, the rotation angle will be input through the control panel, and the motor driver will control the output shaft of the first self-locking motor to rotate the corresponding angle.

[0023] 4. This device, by setting a second self-locking motor in conjunction with the locking teeth on the outside of the positioning ring, allows the pathological specimen to be sampled in an adjustable position as needed. Specifically, the output shaft of the second self-locking motor drives the active gear to move the locking teeth, allowing the pathological specimen, which is fixed inside the positioning ring by the fixing components, to be adjusted clockwise or counterclockwise.

[0024] 5. By setting a pressure sensor, the pressure feedback from the tip sleeve against the pathological specimen is used to detect whether the tip sleeve used to fix the pathological specimen is securely fixed. Attached Figure Description

[0036] 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 of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0037] Please see Figures 1-8An adjustable fixation device for bone tumor pathological specimen collection includes a base 1, a lifting seat 3, an inclined seat 4, a positioning ring 24, and a fixing component. The base 1 is used to fix the device to the operating table. Columns 2 are fixedly installed on both sides of the upper end of the base 1. Lifting seats 3 that can be raised and lowered longitudinally are provided above the columns 2 on both sides. The opposite surfaces of the two lifting seats 3 are rotatably connected to the same inclined seat 4 through a slewing bearing.

[0038] Two support columns 5 are fixedly installed on the upper ends of both sides of the tilting seat 4 by angle brackets. Each support column 5 is rotatably connected to a guide wheel 7 for abutting the guide groove 6. The guide groove 6 is opened on the front and rear surfaces of the positioning ring 24.

[0039] The inner wall of the positioning ring 24 is integrally formed with multiple docking blocks 10 for mounting the front annular shell 8 and the rear annular shell 9. The surfaces of the front annular shell 8 and the rear annular shell 9 are integrally formed with slide rails 12 for mounting the slider 11. The side walls of the front annular shell 8 and the rear annular shell 9 are provided with grooves that are adapted to the docking blocks 10. The front annular shell 8 and the rear annular shell 9 are fixed to the docking blocks 10 by fixing bolts 13 and nuts 14.

[0040] Each slider 11 has a fixed fixing component at its upper end for securing pathological specimens. Considering that currently, when taking samples from pathological surfaces in hospital pathology departments, manual fixing poses safety hazards for medical staff, especially when cutting bone tumor specimens, manual fixing can easily lead to slippage and dangerous situations. This device uses multiple fixing components to fix the pathological specimen in the middle of the positioning ring 24, which is safer than manual fixing. Furthermore, during sampling, the angle of entry can be adjusted by rotating the tilting seat 4. When encountering irregular bone tumor specimens, the lack of secure fixation makes it difficult for medical staff to control the sampling location and size. To address this, a number of fixation components will be installed into the positioning ring 24 as needed. By increasing the fixation points for the pathological specimen, the stability of the device on the pathological surface will be enhanced. Considering the irregularity of the pathological surface, the tip sleeve 29 will be inserted into the pathological specimen to complete the fixation, further strengthening the stability. Furthermore, depending on the size of the pathological specimen, the extension length of the tip sleeve 29 can be controlled by the extension end of the pen-type electric push rod 27.

[0041] Please refer to the figure for details. Considering that the device needs to be stable during use to avoid affecting the sampling due to tilting or moving of the device, clamping plates 15 are provided on both sides of the base 1. The front and rear sides of the upper surface of the two clamping plates 15 are rotatably connected to the mounting bolts 16 through bearings. Multiple mounting bolts 16 are threaded inside the base 1. After the base 1 and the clamping plates 15 come into contact with the table of the operating table, tightening the mounting bolts 16 will cause the clamping plates 15 to be moved, so that the base 1 and the clamping plates 15 are firmly clamped on the operating table.

[0042] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 As shown, considering the differences in height and sampling comfort among medical staff, an electric lifting column 34 is installed inside one of the columns 2, and the telescopic end of the electric lifting column 34 is fixedly connected to one of the lifting seats 3. Guide bars 36 adapted to guide rails 35 are fixedly installed on both sides of the bottom of the two lifting seats 3, and the guide rails 35 are fixedly installed on the side of the column 2. This device will use the telescopic end of the electric lifting column 34 to drive the lifting seat 3 to move longitudinally, thereby completing the lifting process, so that the pathological specimen can be placed at the most comfortable height for medical staff for sampling. At the same time, in order to ensure that no deviation occurs during lifting, the guide rails 35 and guide bars 36 will cooperate to prevent deviation during movement.

[0043] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 As shown, considering that a comfortable operating angle during the process will facilitate medical staff in taking samples from pathological specimens, one of the lifting seats 3 has a cavity inside for installing a first self-locking motor 17. The output shaft of the first self-locking motor passes through the side of the lifting seat 3 and is fixed to the detection shaft of the rotation angle sensor 18. The rotation angle sensor 18 is fixed to the side of the lifting seat 3 by an L-shaped plate, and the rotation angle sensor 18 is electrically connected to the control panel 19 on one side of the column 2. The control panel 19 is also electrically connected to the motor driver 20 inside the cavity through wires. This device uses the first self-locking motor 17 to drive the tilting seat 4 to tilt back and forth, so that the fixed pathological specimen can be rotated to a suitable sampling angle. To ensure accuracy during angle adjustment, the rotation angle is input via control panel 19, and motor driver 20 controls the output shaft of the first self-locking motor 17 to rotate by the corresponding angle. This process can be coordinated with rotation angle sensor 18 to determine the rotation angle of the output shaft of the first self-locking motor 17. Then, the processing chip built into control panel 19 calculates the tilt degree of the tilting seat 4 based on the rotation data of the output shaft of the first self-locking motor 17, thus achieving precise adjustment and simplifying the operation. Later, when the medical staff uses the equipment, they can directly input the number of rotations of the output shaft of the first self-locking motor 17 last time, so that the device can quickly adjust the pathological specimen to the required position.

[0044] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the output shaft of the first self-locking motor is fixedly sleeved with a drive gear 21, and the upper end of the drive gear 21 is meshed with a driven gear 22. The driven gear 22 is fixedly installed on the outside of the rotating end of a slewing bearing on one side. The drive gear 21 drives the driven gear 22.

[0045] Please refer to this carefully. Figure 1 and Figure 6 As shown, a second self-locking motor 14 is installed in the middle of the tilting seat 4 through the chassis. A drive gear 23 is fixed outside the output shaft of the second self-locking motor 14, and the drive gear 23 is meshed with the locking teeth 25 outside the positioning ring 24. By setting the second self-locking motor 14 to cooperate with the locking teeth 25 outside the positioning ring 24, the sampling position of the pathological specimen can be adjusted as needed. That is, the output shaft of the second self-locking motor 14 drives the drive gear 23 to drive the locking teeth 25, so that the pathological specimen inside the positioning ring 24, which is fixed by the fixing component, can be adjusted clockwise or counterclockwise.

[0046] Please refer to this carefully. Figure 2 and Figure 4 As shown, the multiple fixing components include a mounting sleeve 26, a pen-type electric actuator 27, a connector 28, and a tip sleeve 29. The mounting sleeve 26 has an internal cavity for mounting the pen-type electric actuator 27. The telescopic end of the pen-type electric actuator 27 passes through the top of the mounting sleeve 26 and is fixedly connected to the connector 28. The connector 28 is fitted with a tip sleeve 29. The pen-type electric actuator 27 drives the tip sleeve 29 on the outside of the connector 28. This telescopic design allows the device to be adapted and adjusted according to the size of the pathological specimen.

[0047] Please refer to this carefully. Figure 1 and Figure 6 As shown, a pressure sensor 30 is installed on the top of the plug sleeve, and the upper surface of the pressure sensor 30 abuts against the inner surface of the tip sleeve 29. The left and right sides of the tip sleeve 29 are provided with strip grooves 32 for the installation of the limit bolts 31, and the bottom of the limit bolts 31 is threaded into the screw holes opened on both sides of the plug 28. The pressure sensor 30 plays a detection role by detecting the pressure of the tip sleeve 29 against the pathological specimen, so that the device can know whether the tip sleeve 29 used to fix the pathological specimen is firmly fixed.

[0048] Please refer to this carefully. Figure 1 , Figure 4 , Figure 7 and Figure 8As shown, the slide rail 12 has an outer ring structure design, and the middle end of the slide rail 12 has an installation notch for mounting the slider 11. The slider 11 is fixed to the slide rail 12 by the positioning bolt 33 connected by the front thread. The installation notch on the slide rail 12 makes it convenient for medical staff to increase or decrease the number of fixing components as needed.
