Description

Technical Field

[0001] This invention relates to the field of prostate biopsy technology, and in particular to a device for scrotal fixation and postoperative hemostasis during prostate biopsy. Background Technology

[0002] Prostate biopsy is performed under ultrasound or MRI guidance using a special hollow needle to extract a small strip of tissue from the prostate tissue for testing. There are two common methods: transrectal prostate biopsy and transperineal prostate biopsy. Transperineal prostate biopsy is currently the more recommended method due to its lower risk of infection and less pain.

[0003] However, during transperineal prostate puncture, the scrotum is secured by a strap, which passively holds the scrotum in place and cannot effectively lift it upwards. This results in insufficient exposure of the perineum, requiring manual assistance from medical staff and thus affecting the progress of the puncture procedure. Summary of the Invention

[0004] This invention provides a scrotal fixation and postoperative hemostasis device for prostate puncture, which solves the technical problem that the fixation strap passively accommodates the perineum and cannot effectively lift it upwards, resulting in insufficient exposure of the perineum and the need for manual assistance from medical staff, thus affecting the progress of the puncture operation.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A scrotal fixation and postoperative hemostasis device for prostate puncture includes a waist belt, a leg ring fixedly connected to the outer wall of the waist belt, a supporting outer ring fixedly connected to the end of the leg ring away from the waist belt, a supporting plate fixedly connected to the inner ring of the supporting outer ring, and a connecting bridge detachably installed on the outer wall of the supporting plate.

[0007] The connecting bridge has a first working surface and a second working surface opposite to each other. The first working surface is provided with a scrotum support, and the second working surface is provided with an airbag.

[0008] The connecting bridge is provided with an installation component, and the support plate is provided with a mating component that matches the installation component. The installation component is symmetrically arranged with respect to the connecting bridge and parallel to the middle surface of the first working surface and the second working surface.

[0009] A protective component for lifting the scrotum during patient puncture procedures, the protective component being connected to the supporting outer ring and the supporting plate.

[0010] Optionally, the belt is fitted with a buckle, and a pull strap is engaged with the outer wall of the buckle.

[0011] Optionally, a friction strip is fixedly connected to the inner wall of the belt. The friction strip is made of rubber and is bent in the direction of the belt.

[0012] Optionally, the inner wall of the support plate is provided with snap-fit ​​holes and a lower pressure plate;

[0013] The lower pressure plate is a V-shaped elastic sheet, one end of which is fixed to the inner wall of the support plate, and the other end is an open end;

[0014] The mounting component is a spring spring lug located on the side of the bottom of the connecting bridge. The spring spring lug engages with the snap-fit ​​hole. When the connecting bridge deflects, its bottom can press against the open end of the lower pressure plate.

[0015] Optionally, a snap-fit ​​groove is provided at the middle position of the connecting bridge, and a plurality of mesh openings are provided on the outer wall at the middle position of the connecting bridge.

[0016] Optionally, the inner wall of the scrotum support is fixedly connected with a plurality of support columns, the support columns being made of rubber and arranged in an array on the outer wall of the scrotum support.

[0017] Optionally, the inner wall of the support column is hollow, and an adapter column is fixedly connected to the inner wall of the support column, with both ends of the adapter column fixedly connected to the inner wall of the scrotum support.

[0018] Optionally, a roller is installed at the end of the support column away from the scrotum support, and the roller is made of rubber.

[0019] Optionally, the outer wall of the connecting bridge is fixedly connected with Velcro.

[0020] Optionally, the air inlet of the airbag is equipped with an inflation tube, a low pressure gauge is fixedly connected to the outer wall of the airbag, and a connecting column is provided on the outer wall of the airbag near the connecting bridge.

[0021] The beneficial effects of the above-described technical solution of the present invention are as follows:

[0022] In the above scheme, by setting up protective components, not only can medical staff not manually pull up the scrotum during the puncture process, fully exposing the scrotum to the outside, achieving a working state where one person can operate without an assistant, but also the state of the scrotum can be observed at any time during and after the operation through the set mesh, ensuring the puncture is carried out.

[0023] By incorporating a support plate, traction strap, and friction strip into the protective components, the position of the waist belt and leg rings after wearing is further secured. This ensures that even slight shaking during the patient's puncture will not cause the support plate to shift, guaranteeing the normal and efficient execution of the puncture procedure.

[0024] By incorporating support columns, adapter columns, and rollers into the protective components, the scrotum can be fitted onto the connecting bridge according to the size and dimensions of different patients, improving the fixation of the scrotum during puncture. This process is also more flexible and convenient, increasing the progress and efficiency of the puncture procedure.

[0025] By setting up airbags, dual independent operation, precise compression targeting, and independent adjustment of pressure on both sides, the pressure can be quantitatively controlled using existing micro-inflatable balloon structures, avoiding insufficient compression leading to bleeding or excessive compression leading to ischemia and necrosis, thus achieving personalized compression management.

[0037] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0038] like Figures 1 to 9 As shown, an embodiment of the present invention provides a scrotal fixation and postoperative hemostasis device for prostate puncture, including a waist belt 1, a leg ring 3 fixedly connected to the outer wall of the waist belt 1, a supporting outer ring 4 fixedly connected to the end of the leg ring 3 away from the waist belt 1, a supporting plate 7 fixedly connected to the inner ring of the supporting outer ring 4, and a connecting bridge 8 detachably installed on the outer wall of the supporting plate 7; the connecting bridge 8 has a first working surface and a second working surface opposite to each other, a scrotal support 14 is provided on the first working surface, and an airbag 20 is provided on the second working surface; an installation component is provided on the connecting bridge 8, and a mating component matching the installation component is provided on the supporting plate 7, the installation component being symmetrically arranged relative to the connecting bridge 8 and parallel to the middle symmetrical surface of the first working surface and the second working surface; a protective component is used to lift the scrotum during the patient's puncture operation, and the protective component is connected to the supporting outer ring 4 and the supporting plate 7.

[0039] After the patient puts on the waist belt 1 and leg rings 3, the connecting bridge 8 is inserted into the mating parts on the support plate 7 using symmetrically arranged mounting parts. At this time, the first working surface of the connecting bridge 8 (with scrotum support 14) faces the patient, the scrotum is placed in the scrotum support 14, and then the scrotum is pulled upward by the protective components to fix the connecting bridge 8 in the pulled position, fully exposing the perineum, and the doctor can then perform the puncture independently.

[0040] After the puncture is completed, loosen the protective components, remove the connecting bridge 8, and rotate it vertically 180° so that the second working surface (with the airbag 20) faces the patient. Then, use the symmetrically arranged mounting pieces to re-lock the support plate 7. Subsequently, inflate the airbag 20 to apply targeted compression to the puncture site for hemostasis.

[0041] Using this device, the scrotum can be manually lifted without an assistant, allowing a single person to complete the puncture procedure, thus improving surgical efficiency. The same connecting bridge 8 can be flipped to switch between "intraoperative exposure" and "postoperative compression" modes without changing instruments, making it convenient to use. The inflatable balloon 20, combined with the symmetrical installation structure, provides stable and uniform hemostatic pressure.

[0042] Furthermore, both the waist belt 1 and the leg ring 3 are made of ergonomic materials. The waist belt 1, buckle 2 and leg ring 3 are existing structures, so we will not go into details. The buckle 2 has holes on its outer wall. The supporting outer ring 4 is made of soft plastic. The supporting plate 7, which serves as the supporting base, is made of plastic. The connecting bridge 8 is made entirely of soft plastic and can come into direct contact with human skin.

[0043] By setting up protective components, not only can medical staff not manually pull up the scrotum during the puncture process, fully exposing the scrotum and achieving a working state where one person can operate without an assistant, but also the state of the scrotum can be observed at any time during and after the procedure through the set mesh 13, ensuring the puncture can proceed smoothly.

[0044] like Figures 3 to 6 As shown, the protective assembly includes a support plate 5 fixedly connected to the outer wall of the support plate 7, a buckle 2 fitted on the waist belt 1, a tension strap 6 snapped onto the outer wall of the buckle 2, and a friction strip 9 fixedly connected to the inner wall of the waist belt 1. The friction strip 9 is made of rubber and is bent toward the waist belt 1.

[0045] Furthermore, the support plate 5 is made of plastic, the traction belt 6 is made of the same material as the waist belt 1 and leg ring 3, which is ergonomic material, and the inner wall of the friction strip 9 is hollow, which can be deformed.

[0046] Furthermore, the inner wall of the support plate 7 is provided with a snap-fit ​​hole 11 and a lower pressure plate 10; the lower pressure plate 10 is a V-shaped elastic sheet, one end of which is fixed to the inner wall of the support plate 7, and the other end is an open end; the mounting component is a spring lug 15 provided on the side of the bottom of the connecting bridge, the spring lug 15 is snapped into the snap-fit ​​hole 11, and when the connecting bridge 8 deflects, its bottom can press against the open end of the lower pressure plate 10.

[0047] Furthermore, the lower pressure plates 10 are vertically arrayed in the inner wall of the support plate 7. The lower pressure plates 10 are made of plastic, and their open ends can move towards the fixed ends when squeezed by the bottom of the connecting bridge 8, causing the V-shaped elastic sheet to elastically close.

[0048] Before the puncture, the waist belt 1 and leg rings 3 are passed through the patient's buttocks and waist, ensuring that the waist belt 1 is fixed to the patient's waist. The patient's legs are passed between the upper and lower leg rings 3, similar to the way underwear is worn. During the wearing process, it is necessary to ensure that the waist belt 1 fits snugly against the patient's waist. Since the patient is in a supine position during the puncture, the patient's back is pressed on the waist belt 1, which prevents the waist belt 1 from shifting too much. In order to improve comfort during the puncture, the waist belt 1 does not need to be worn tightly. The tightness of the leg rings 3 will change with the tightness of the waist belt 1. Overall, during the puncture process, it is only necessary to ensure that the waist belt 1 and leg rings 3 are correctly worn on the patient's waist and legs. After the waist belt 1 and leg rings 3 are correctly worn, it is convenient to fix the traction belt 6 later.

[0049] After securing the patient with the waist belt 1 and leg rings 3, place the support plate 5 diagonally under the patient's buttocks. Since the patient is in a supine position, the patient's buttocks need to be lifted first. After the support plate 5 is placed flat, the patient's buttocks are pressed on the support plate 5 and the buttocks are gently rocked to adjust, ensuring the patient's comfort during the compression process. During the wearing of the waist belt 1, the friction strip 9 may deform to varying degrees. Since the friction strip 9 is made of rubber, in order to ensure the comfort of the waist pressing on the waist belt 1 during the puncture, the friction strip 9 also needs to be adjusted. It is necessary to ensure that the friction strip 9 is in the same direction and in a non-deformed state. One end of the traction strap 6 is snapped into the hole of the buckle 2, while the other end is left unsecured. Finally, the dressing operation is completed, and the core structure of the protective component, such as the support plate 7, is also located around the patient's perineum.

[0050] It is worth mentioning that during the wearing of the waist belt 1 and leg ring 3, the tightness can be adjusted using buckle 2 to avoid excessive tightness affecting blood circulation. At the same time, it is also necessary to ensure that the middle structure of the protective components is directly below the patient's perineum during the wearing process. After the operation, the waist belt 1 and leg ring 3 can be disinfected, washed and reused as the wearing structure, and are suitable for patients of different ages and body types, and are firmly fixed to the patient's body by physical restraint.

[0051] By incorporating a support plate 5, a traction belt 6, and a friction strip 9 into the protective assembly, the waist belt 1 and leg ring 3 are further secured in their worn state. This ensures that even slight shaking during patient puncture will not cause the support plate 7 to shift, thus guaranteeing the normal and efficient execution of the puncture procedure.

[0052] like Figures 7 to 9As shown, a snap-fit ​​groove 12 is provided in the middle of the connecting bridge 8, and a number of meshes 13 are provided on the outer wall of the middle of the connecting bridge 8. A number of supporting columns 16 are fixedly connected to the inner wall of the scrotum support 14. The inner wall of the supporting column 16 is hollow. An adapter column 17 is fixedly connected to the inner wall of the supporting column 16. Both ends of the adapter column 17 are fixedly connected to the inner wall of the scrotum support 14. A roller 18 is installed at the end of the supporting column 16 away from the scrotum support 14. The roller 18 is made of rubber.

[0053] The outer wall of the connecting bridge 8 is fixedly connected with Velcro 19. The air inlet of the airbag 20 is equipped with an inflation tube 21. The outer wall of the airbag 20 is fixedly connected with a low pressure gauge 22. The outer wall of the buckle 2 has a slot, the size of which is the same as the size of the snap-fit ​​slot 12. The support columns 16 are made of rubber and are arrayed on the outer wall of the scrotum support 14. The airbag 20 has a connecting column near the outer wall of the connecting bridge 8. There are a total of 5 support columns 16. One end of the adapter column 17 is fixed to the outer wall of the scrotum support 14, and the other half is fixed to the inner wall of the lowest support column 16. The adapter column 17 is made of metal wire and can be manually bent and deformed.

[0054] After securing the waist belt 1 and leg ring 3 to the patient, press and snap the spring lug 15 at the bottom of the connecting bridge 8 into the snap-fit ​​hole 11. After releasing the spring lug 15, it automatically snaps into the snap-fit ​​hole 11. At this time, the two ends of the connecting bridge 8 are not completely attached to the inner wall of the support plate 7 due to the contact of the spring lug 15. The initial fixation of the connecting bridge 8 is completed only by the snap-fit ​​of the spring lug 15 and the snap-fit ​​hole 11.

[0055] At this time, the connecting bridge 8 can deflect downward under the action of external force, and the bottom of the connecting bridge 8 abuts against the top of the lower pressure plate 10. If the connecting bridge 8 deflects downward, the bottom of the connecting bridge 8 will squeeze the lower pressure plate 10, thereby causing the V-shaped opening of the lower pressure plate 10 to close elastically. Then, after the connecting bridge 8 is fixed, the unfixed end of the traction strap 6 is snapped into the snap-fit ​​groove 12 at the top of the connecting bridge 8. Before the scrotum is lifted, there is no need to adjust the length of the traction strap 6; only preliminary fixation is required.

[0056] Then start manually pushing the outer wall of connecting bridge 8, such as Figure 7As shown, the top of the connecting bridge 8 is deflected from the left to the right. Under the action of the spring lug 15, the top of the connecting bridge 8 deflects while the bottom does not. The deflection of the connecting bridge 8 causes the bottom of the connecting bridge 8 to press against the top of the lower pressure plate 10, thereby closing the V-shaped opening of the lower pressure plate 10. Then, the patient's scrotum is lifted upwards, and the connecting bridge 8 needs to be deflected continuously until the scrotum and the connecting bridge 8 are completely in contact. The degree of contact between the lifting post 16 and the scrotum is observed through the mesh 13. During the process of lifting the scrotum, it is only necessary to ensure that the perineum is completely covered. The scrotum should be fully exposed to the eye. At this point, observe through the mesh 13 whether there is any loose fit during the compression process. If so, gently shake the scrotum or the connecting bridge 8. During the shaking, the support column 16 and the adapter column 17 will automatically fit with the scrotum while the roller 18 is sliding. The adapter column 17 not only improves the stability of the support column 16 during the fit between the support column 16 and the scrotum, but also allows the connecting bridge 8 to be removed separately before wearing to adjust the fit of the patient's scrotum and manually bend the path of the adapter column 17.

[0057] Finally, once the scrotum is fully fitted to the scrotum support 14, observe the condition of the scrotum through the mesh 13. If there is no redness or congestion due to compression or if it cannot fit properly within the scrotum support 14, adjust the length of the traction strap 6 until it is completely taut. This will firmly fix the connecting bridge 8 at a certain angle of deflection. Without any other external force, the connecting bridge 8 will be in a stable state, and the patient's perineum will be fully exposed. Then, begin the puncture procedure.

[0058] After the puncture procedure, detach one end of the traction strap 6. At this point, the connecting bridge 8 loses its forward tension and its bottom will not press against the pressure plate 10. The pressure plate 10 will then begin to reset and spring upward, bringing the connecting bridge 8 back to its initial vertical position. Because the spring lugs 15 are in contact with the pressure plate 10, the two sides of the connecting bridge 8 will not be completely fitted into the inner wall of the support plate 7. At this point, push the connecting bridge 8 to one side and press the spring lugs 15, causing the spring lugs 15 on the other side to dislodge from the snap-fit ​​hole 11. Remove the connecting bridge 8 and rotate it 180° vertically so that the side with the airbag 20 is closer to the scrotum. Similarly, snap the connecting bridge 8 back onto the support plate 7, following the same steps. Once the connecting bridge 8 is fixed, as shown... Figure 9 As shown, the mesh 13 at the front will fit the scrotum. Since the front and back of the connecting bridge 8 are made of the same material, the scrotum can be supported. The only difference is that the connecting bridge 8 after being flipped over does not have the inwardly recessed scrotum support 14 in the middle. Its purpose is not to perform puncture. There is no need to expose a large area of ​​the perineum. It is only necessary to ensure that the position of the airbag 20 is on both sides of the puncture point in the perineum.

[0059] At this point, regarding the fit between the connecting bridge 8 and the scrotum, since the airbag 20 needs to be inflated, it is not necessary to press the connecting bridge 8 tightly against the patient's scrotum. Finally, the traction strap 6 needs to be fixed. It is only necessary to ensure that the connecting bridge 8 can lift the scrotum up.

[0060] Finally, inflation begins. Using an existing micro-inflatable balloon, connect the inflation tubing 21 to allow the airbag 20 to expand. Inflate one side of the airbag 20 first, asking the patient about their feelings and condition while inflating, until the patient feels comfortable and experiences a uniform pressure. Observe the value on the low pressure gauge 22. Inflate the other side according to the value, but continue to ask the patient about their condition during inflation.

[0061] It is worth mentioning that some patients have sensitive scrotums, so an additional layer of soft mesh 13 can be added during the operation and attached to the surface of the connecting bridge 8 using Velcro 19. Multiple Velcro 19s are provided on both sides of the connecting bridge 8 to improve the comfort of puncture and postoperative hemostasis. At the same time, patients can wear it while walking and going to the toilet. Before wearing it while walking, the waist belt 1 needs to be tightened. After tightening, the waist belt 1 will not slip downwards under the action of the friction strip 9.

[0062] For patients who are using the device after surgery to engage in activities such as urination and walking, medical staff should check the puncture site for bleeding every 30 minutes for 1-2 hours after surgery and observe pressure changes using a low-pressure gauge 22. If the pressure drops, the device can be inflated. If the patient experiences pain or swelling, the device can be deflated appropriately. The compression time after the puncture should follow the clinical routine requirements. After the procedure, the air bag should be deflated first, and then other structures such as the connecting bridge 8 should be removed. Finally, the waist belt 1 and leg ring 3 should be removed, and the healing status should be recorded.

[0063] Furthermore, the entire connecting bridge 8 is a disposable product and needs to be medically recycled after the puncture and hemostasis procedures are completed, while the waist belt 1 and leg ring 3, as wearable structures, can be disinfected with alcohol and washed for reuse.

[0064] By incorporating a support column 16, an adapter column 17, and a roller 18 into the protective assembly, the scrotum can be adapted to the size and dimensions of different patients when it is attached to the connecting bridge 8. This improves the fixation of the scrotum during puncture and makes the fixation process more flexible and convenient, thereby increasing the progress and efficiency of the puncture operation.

[0065] By setting up airbag 20, dual independent operation is achieved, and the compression is precisely targeted. The pressure on both sides can be adjusted independently. The pressure can be quantitatively controlled by using the existing structure of the micro-inflatable balloon, avoiding insufficient compression causing bleeding or excessive compression causing ischemia and necrosis, thus realizing personalized compression management.

[0066] The working process of the scrotal fixation and postoperative hemostasis device for prostate puncture provided by this invention is as follows:

[0067] Before the puncture, the waist belt 1 and leg rings 3 are passed through the patient's buttocks and waist, ensuring that the waist belt 1 is fixed to the patient's waist. The patient's legs are passed between the upper and lower leg rings 3, similar to the way underwear is worn. During the wearing process, it is necessary to ensure that the waist belt 1 fits snugly against the patient's waist. Since the patient is in a supine position during the puncture, the patient's back is pressed on the waist belt 1, which prevents the waist belt 1 from shifting too much. In order to improve comfort during the puncture, the waist belt 1 does not need to be worn tightly. The tightness of the leg rings 3 will change with the tightness of the waist belt 1. Overall, during the puncture process, it is only necessary to ensure that the waist belt 1 and leg rings 3 are correctly worn on the patient's waist and legs. After the waist belt 1 and leg rings 3 are correctly worn, it is convenient to fix the traction belt 6 later.

[0068] After securing the patient with the waist belt 1 and leg rings 3, place the support plate 5 diagonally under the patient's buttocks. Since the patient is in a supine position, first lift the patient's buttocks. Once the support plate 5 is flat, press the patient's buttocks onto the support plate 5 and gently wiggle the buttocks to adjust, ensuring the patient's comfort during the compression process. During the wearing of the waist belt 1, the friction strips 9 may deform to varying degrees. Given that the friction strips 9 are made of rubber, to ensure comfort during the puncture procedure, the friction strips 9 also need adjustment. Ensure that all friction strips 9 are in the same direction and in a non-deformed state. Secure one end of the traction strap 6 in the hole of the buckle 2, leaving the other end unsecured. Finally, the donning procedure is complete.

[0069] After securing the waist belt 1 and leg ring 3 to the patient, press and snap the spring spring lug 15 at the bottom of the connecting bridge 8 into the snap-fit ​​hole 11. After releasing the spring spring lug 15, it automatically snaps into the snap-fit ​​hole 11. At this time, the two ends of the connecting bridge 8 are not completely attached to the inner wall of the support plate 7 due to the resistance of the spring spring lug 15. Only the snap-fit ​​between the spring spring lug 15 and the snap-fit ​​hole 11 completes the initial fixation of the connecting bridge 8. At this time, the connecting bridge 8 can be deflected downward under the action of external force and squeeze the lower pressure plate 10, thereby causing the V-shaped opening of the lower pressure plate 10 to close elastically.

[0070] Next, lift the patient's scrotum upwards while continuing to deflect the connecting bridge 8 until the scrotum and the connecting bridge 8 are completely in contact. Observe the degree of contact between the lifting column 16 and the scrotum through the mesh 13. At this time, observe through the mesh 13 whether there is any situation where the scrotum is not tightly attached during the squeezing process. If so, it is necessary to gently shake the scrotum or the connecting bridge 8. During the shaking process, the lifting column 16 and the adapter column 17 will automatically fit into contact with the scrotum while the roller 18 is sliding.

[0071] Finally, once the scrotum is completely fitted to the scrotum support 14, observe the condition of the scrotum through the mesh 13. If there is no redness or congestion due to compression or if it cannot fit properly within the scrotum support 14, then adjust the length of the traction band 6 until it is completely taut and begin the puncture procedure.

[0072] After the puncture is completed, detach one end of the traction strap 6, hold one side of the connecting bridge 8 and push and squeeze the spring spring 15 so that the spring spring 15 on the other side falls out of the snap-fit ​​hole 11. Take out the connecting bridge 8 and rotate it 180° in a vertical position so that the side of the airbag 20 is close to the scrotum. Similarly, snap the connecting bridge 8 back onto the support plate 7, following the same steps.

[0073] Finally, inflation begins. Using an existing micro-inflatable balloon, connect the inflation tubing 21 to allow the airbag 20 to expand. Inflate one side of the airbag 20 first, asking the patient about their feelings and condition while inflating, until the patient feels comfortable and experiences a uniform pressure. Observe the value on the low pressure gauge 22. Inflate the other side according to the value, but continue to ask the patient about their condition during inflation.

[0074] In the above scheme, by setting up protective components, not only can medical staff not manually pull up the scrotum during the puncture process, fully exposing the scrotum to the outside, achieving a working state where one person can operate without an assistant, but also the state of the scrotum can be observed at any time during and after the operation through the set mesh 13, ensuring the puncture is carried out.

[0075] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
