Description

Technical Field

[0001] This application relates to the field of prostate cancer diagnostic technology, and in particular to a prostate cancer bone metastasis risk prediction diagnostic device. Background Technology

[0002] Prostate cancer is an epithelial malignant tumor that occurs in the prostate. In 2012, the incidence rate of prostate cancer in cancer registry areas in my country was 9.92 / 100,000, ranking 6th among male malignant tumors. The incidence rate is relatively low before the age of 55, and gradually increases after the age of 55. The incidence rate increases with age, with the peak age being 70-80 years old.

[0003] Bone metastasis is a disease characterized by bone damage and pain caused by the hematogenous spread of certain malignant tumors originating outside the bone tissue to the bone tissue. Currently, in predicting the risk of bone metastasis in prostate cancer, prostate examination is required. The following are some methods for detecting prostate cancer: digital rectal examination, transrectal ultrasound, CT, MRI, and bone ECT. Among them, digital rectal examination can help determine the enlargement of the prostate gland, hard nodules, unevenness, disappearance of the median sulcus, and gland fixation.

[0004] Currently, patients undergoing digital rectal examinations are required to assume a knee-chest position, left lateral decubitus position, or supine position. For patients with abdominal diseases or those who are physically weak, the supine position is generally used, and assistance from others is required during the examination, which is quite inconvenient. Therefore, a diagnostic device for predicting the risk of bone metastasis in prostate cancer is proposed. Summary of the Invention

[0005] The purpose of this application is to address the problem that patients with abdominal diseases or physical weakness generally need to lie supine and require assistance during digital rectal examination, which is inconvenient. This application provides a device for predicting and diagnosing the risk of bone metastasis in prostate cancer.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A diagnostic device for predicting the risk of bone metastasis in prostate cancer includes a diagnostic table. Two support rods are symmetrically arranged on one side of the diagnostic table, and support plates are provided on the sides of the two support rods that are far apart from each other. Adjustment components for adjusting the position of the support plates are provided on the support rods. A connecting block is fixed to one end of the diagnostic table. A movable groove is constructed inside the connecting block. A movable block is fixed to the bottom end of the support rod. The movable block is slidably connected in the movable groove. A driving mechanism for driving the two movable blocks to move closer or further apart is provided inside the connecting block. A risk marking component is provided on one side of the connecting block.

[0008] By adopting the above technical solution, when a patient needs to undergo digital rectal examination, the patient lies on the examination table, and then the bent parts of the patient's legs are placed on two support plates respectively. Then, the two movable blocks are driven away from each other by the drive mechanism, which in turn drives the two support rods and two support plates away from each other, thereby bending and separating the patient's legs, so that the patient is in a supine position, which makes it convenient for staff to perform supine digital rectal examination on the patient.

[0009] Furthermore, the adjustment assembly includes a slider fixed to one end of the support plate, a groove is constructed on the support rod along its height direction, the slider is slidably connected in the groove, the support rod is rotatably connected to an adjustment screw located in the groove, the adjustment screw is arranged along the height direction of the support rod and is threadedly connected to the slider, and a knob is fixed at the top of the adjustment screw.

[0010] By adopting the above technical solution, turning the knob can drive the adjusting screw to rotate. Since the adjusting screw is threadedly connected to the slider, the adjusting screw can drive the slider to slide along the slide groove when it rotates, thereby driving the support plate to move through the slider, thus adjusting the position of the support plate.

[0011] Furthermore, a protective pad is fixed to the top of the support plate, and the support plate and the protective pad are connected by an airbag.

[0012] By adopting the above technical solutions, the contact between the protective pad and the patient's skin can reduce harm to the patient, and the airbag pad can provide some cushioning when the patient sets up their legs.

[0013] Furthermore, the driving mechanism includes a movable block disposed in the movable slot, and a bidirectional lead screw is rotatably connected to the movable block. The threads on both sides of the bidirectional lead screw have opposite directions, and the two sides of the bidirectional lead screw are respectively threadedly connected to two movable blocks.

[0014] Furthermore, the connecting block has a movable groove communicating with the movable groove along the height direction of the diagnostic table. The movable block is slidably connected in the movable groove. A cavity is constructed inside the movable block. A bevel gear one is fixed in the cavity by the bidirectional lead screw. A rotating shaft is rotatably connected to the bottom of the movable block. A bevel gear two is fixed to the top of the rotating shaft. The bevel gear two is located in the cavity and meshes with the bevel gear one.

[0015] Furthermore, the bidirectional lead screw is located in the movable groove, the bottom of the connecting block is constructed with a through hole communicating with the movable groove, the rotating shaft is inserted into the through hole and a handle is fixed at the bottom of the rotating shaft.

[0016] By adopting the above technical solution, rotating the handle can drive the rotating shaft to rotate, which in turn drives the bevel gear two at its top to rotate. When the bevel gear two rotates, it can drive the bevel gear one and the double-acting screw to rotate. When the double-acting screw rotates, it drives the two movable blocks to move closer or further away from each other along the movable groove, which in turn drives the two support rods to move closer or further away from each other.

[0017] Furthermore, the connecting block is fixedly located within the movable groove, and the movable block has an inclined groove on the side near the fixed block. The end of the inclined groove near the movable block is higher, and the fixed block is slidably connected within the inclined groove.

[0018] By adopting the above technical solution, when the handle is turned and the two movable blocks move away from each other along the movable groove, the slider will move in the groove, thereby forcing the two movable blocks to move downward synchronously, and then adjusting the support position according to the bending and opening of the patient's limb.

[0019] Furthermore, the risk marking component includes a marking disk fixed to one side of the connecting block, a handle fixedly connected to the center of the marking disk, an age scale ring fixed to the outer wall of the handle, and a specific antigen scale ring, a prostate volume scale ring, and a clinical variable scale ring sequentially rotatably connected to the outer periphery of the age scale ring on the marking disk, and a risk scale bar constructed on the outer wall of the marking disk.

[0020] By adopting the above technical solution, the specific antigen scale ring, prostate volume scale ring, and clinical variable scale ring are rotated sequentially according to the patient's condition. The zero mark of the outer scale ring is aligned with the index of the current scale ring as needed. The final risk index is obtained by superimposing the data and the risk scale bar.

[0021] Furthermore, a connecting plate is fixed to one side of the handle, and multiple limiting bolts are threaded onto the connecting plate. The multiple limiting bolts respectively abut against the specific antigen scale ring, the prostate volume scale ring, and the clinical variable scale ring.

[0022] By adopting the above technical solution, after the corresponding limiting bolts are tightened, the rotation of the corresponding scale ring can be limited by the contact of the limiting bolts, so as to avoid displacement of the scale ring during the marking process.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. When a patient needs a digital rectal examination, the patient lies on the examination table, and the bent parts of the patient's legs are placed on two support plates. The two movable blocks are then driven away from each other by a drive mechanism, thus bending and separating the patient's legs, placing the patient in a supine position. This facilitates the supine digital rectal examination for staff, allowing staff to independently perform digital rectal examinations on patients with abdominal diseases or who are physically weak. Simply having the patient lie on the examination table and bending and separating their legs is sufficient for the digital rectal examination. When hospital staff are busy, the examination can be performed independently, thus reducing the waste of medical resources.

[0025] 2. After examining the patient's prostate condition, the specific antigen scale ring, prostate volume scale ring, and clinical variable scale ring are adjusted according to the patient's age and the examination results to obtain the corresponding risk index of bone metastasis of prostate cancer. This allows for the examination and treatment of the patient based on the pre-established examination and treatment plans, reducing the workload of staff while ensuring the accuracy and rationality of the examination and treatment as much as possible.

[0034] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0035] This application discloses a device for predicting and diagnosing the risk of bone metastasis in prostate cancer.

[0036] Reference Figure 1 , Figure 2 and Figure 3 A diagnostic device for predicting the risk of bone metastasis in prostate cancer includes a diagnostic table 1. Two support rods 2 are symmetrically arranged on one side of the diagnostic table 1. Support plates 3 are provided on the sides of the two support rods 2 that are far apart from each other. Adjustment components for adjusting the position of the support plates 3 are provided on the support rods 2. A connecting block 4 is fixed to one end of the diagnostic table 1. The connecting block 4 has a movable groove. A movable block 5 is fixed to the bottom end of the support rods 2. The movable block 5 is slidably connected in the movable groove. A driving mechanism for driving the two movable blocks 5 to move closer or further apart is provided in the connecting block 4. A risk marking component is provided on one side of the connecting block 4.

[0037] When a digital rectal examination is required, the patient lies on the examination table 1, and the bent parts of the patient's legs are placed on two support plates 3 respectively, thus bending the patient's legs. Then, the drive mechanism drives two movable blocks 5 to move away from each other, which in turn moves the two support rods 2 and the two support plates 3 away from each other, thereby bending and separating the patient's legs, so that the patient is in a supine position. This facilitates the staff to perform a supine digital rectal examination to detect the condition of the patient's prostate, thereby making a preliminary diagnosis of whether the patient has prostate cancer. Then, based on the patient's age and prostate condition, the risk of bone metastasis is predicted, and the risk is marked by a risk marking component, which facilitates the staff to formulate corresponding examination and treatment plans based on the risk marking.

[0038] This design allows staff to perform digital rectal examinations independently on patients with abdominal ailments or those who are physically weak. The procedure can be performed simply by having the patient lie on the examination table 1 and bending and separating their legs. When hospital staff are busy, the examination can be conducted independently, thus reducing the waste of medical resources.

[0039] After assessing the patient's prostate condition, and considering the patient's age and prostate condition, a risk marker component is used to predict and mark the risk of bone metastasis in the patient's prostate cancer. After marking the patient's risk of bone metastasis, staff can develop corresponding examination and treatment plans based on the risk markers. By implementing the plans developed in advance according to the risk markers, the workload of staff can be reduced.

[0040] Reference Figure 2 and Figure 3 The adjustment assembly includes a slider 6 fixed to one end of the support plate 3. A groove is constructed on the support rod 2 along its height direction. The slider 6 is slidably connected in the groove. The support rod 2 is rotatably connected to an adjustment screw 7 located in the groove. The adjustment screw 7 is set along the height direction of the support rod 2 and is threadedly connected to the slider 6. A knob 8 is fixed at the top of the adjustment screw 7.

[0041] A protective pad 9 is fixed to the top of the support plate 3, and the support plate 3 and the protective pad 9 are connected by an airbag.

[0042] When in use, turning the knob 8 will drive the adjusting screw 7 to rotate. Since the adjusting screw 7 is threadedly connected to the slider 6, the adjusting screw 7 can drive the slider 6 to slide along the slide groove when it rotates, thereby driving the support plate 3 to move through the slider 6, thus adjusting the position of the support plate 3.

[0043] With this design, when the patient's legs are long, turning the knob 8 moves the support plate 3 upward along the support rod 2; when the patient's legs are short, turning the knob 8 moves the support plate 3 downward along the support rod 2. This allows the position of the support plate 3 to be adjusted to accommodate patients of different body types. At the same time, the protective pad 9, which comes into contact with the patient's skin, reduces harm to the patient. Furthermore, the airbag cushion provides some cushioning when the patient sets up their legs, thus protecting the patient's legs as much as possible.

[0044] Reference Figure 3 and Figure 4 The drive mechanism includes a movable block 10 disposed in the movable slot, and a bidirectional lead screw 11 is rotatably connected to the movable block 10. The threads on both sides of the bidirectional lead screw 11 have opposite directions, and the two sides of the bidirectional lead screw 11 are respectively threaded to two movable blocks 5.

[0045] The connecting block 4 has a movable groove connected to the movable groove along the height direction of the diagnostic table 1. The movable block 10 is slidably connected in the movable groove. The movable block 10 has a cavity. The bidirectional lead screw 11 is located in the cavity and a bevel gear 12 is fixed therein. The bottom of the movable block 10 is rotatably connected to the rotating shaft 13. The top of the rotating shaft 13 is fixed with a bevel gear 14. The bevel gear 14 is located in the cavity and meshes with the bevel gear 12.

[0046] The bidirectional lead screw 11 is located in the movable groove. The bottom of the connecting block 4 is constructed with a through hole that communicates with the movable groove. The rotating shaft 13 is inserted into the through hole and a handle 15 is fixed at the bottom of the rotating shaft 13.

[0047] When in use, turn the handle 15 to drive the rotating shaft 13 to rotate, which in turn drives the bevel gear 14 at its top to rotate. Since the bevel gear 12 meshes with the bevel gear 14, the rotation of the bevel gear 14 can drive the bevel gear 12 and the double-acting screw 11 to rotate. Since the two sides of the double-acting screw 11 are threadedly connected to two movable blocks 5 respectively, when the double-acting screw 11 rotates, it drives the two movable blocks 5 to move closer or further away from each other along the movable groove, which in turn drives the two support rods 2 to move closer or further away from each other.

[0048] With this design, when the patient's legs are placed on the two support plates 3 respectively, turning the handle 15 will cause the two support rods 2 to move away from each other, thereby separating the patient's legs and keeping the patient in a supine position, which is convenient for staff to perform digital rectal examination. After the patient's examination is completed, turning the handle 15 in the opposite direction will cause the two support rods 2 to move closer to each other, thereby bringing the patient's legs together and making it easier to remove the patient's legs.

[0049] Reference Figure 5 The connecting block 4 is fixed with a fixed block 16 in the movable groove. The movable block 5 has an inclined groove 17 on the side near the fixed block 16. The end of the inclined groove 17 near the movable block 10 is higher. The fixed block 16 is slidably connected in the inclined groove 17.

[0050] When the handle 15 is turned, the two movable blocks 5 move away from each other along the movable groove. The slider 6 moves in the groove, which forces the two movable blocks 5 to move downward synchronously. This allows the two movable blocks 5 to move downward synchronously while moving away from each other, thereby driving the two support rods 2 and the two support plates 3 to move synchronously.

[0051] With this design, when the two support plates 3 move away from each other to separate the patient's legs, the two support plates 3 will move downwards synchronously, thereby adjusting the support position according to the bending and opening of the patient's limbs. This can minimize the possibility of pulling or even damaging the patient's legs when separating them.

[0052] Reference Figure 1 and Figure 6 The risk marking component includes a marking disk 18 fixed to one side of the connecting block 4. A handle 19 is fixedly connected to the center of the marking disk 18. An age scale ring 20 is fixed to the outer wall of the handle 19. A specific antigen scale ring 21, a prostate volume scale ring 22, and a clinical variable scale ring 23 are sequentially rotatably connected to the outer periphery of the age scale ring 20 on the marking disk 18. A risk scale bar 24 is constructed on the outer wall of the marking disk 18.

[0053] A connecting plate 25 is fixed to one side of the handle 19. Multiple limiting bolts 26 are threaded onto the connecting plate 25. The multiple limiting bolts 26 respectively abut against the specific antigen scale ring 21, the prostate volume scale ring 22 and the clinical variable scale ring 23.

[0054] When using the device, rotate the specific antigen scale ring 21, the prostate volume scale ring 22, and the clinical variable scale ring 23 in sequence according to the patient's condition. Align the zero mark of the outermost scale ring with the index of the current scale ring as needed. The final risk index is then obtained by superimposing the data and using the risk scale bar 24.

[0055] When rotating the specific antigen scale ring 21, the prostate volume scale ring 22, and the clinical variable scale ring 23 in sequence, tighten the corresponding limiting bolts 26. This restricts the rotation of the corresponding scale rings by the contact of the limiting bolts 26, thus minimizing displacement of the scale rings during the marking process and ensuring the accuracy of the risk index as much as possible.

[0056] This design allows for the adjustment of multiple scale rings based on the patient's age and examination results after prostate examination to obtain a corresponding risk index for bone metastasis of prostate cancer. This enables the patient to undergo examination and treatment according to a pre-determined examination and treatment plan, reducing the workload of staff while ensuring the accuracy and rationality of testing and treatment.
