Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a prostate puncture positioning auxiliary component. Background Technology
[0002] Prostate biopsy is a minimally invasive surgical procedure. Under ultrasound guidance, a fine needle is precisely inserted into the prostate gland using transrectal ultrasound equipment to extract a strip of prostate tissue for pathological examination. This is the "gold standard" method for diagnosing prostate cancer. During the procedure, the patient needs to lie supine on the operating table with both legs raised so that the puncture site is fully exposed to the doctor's view.
[0003] However, for obese patients, due to the thicker fat in their buttocks, even if the patient raises their legs, the anus is not fully exposed, which makes it difficult for the ultrasound probe to be inserted into the rectum smoothly, thus affecting the success of the surgery. When performing prostate puncture, it is usually necessary to properly fix the penis and scrotum to ensure that the puncture needle can accurately reach the target area of the prostate. At present, gauze and tape are often used in clinical practice to fix the scrotum and penis to the patient's abdomen. However, this method is not only cumbersome, but also difficult to guarantee the stability of fixation. If the tape separates during the operation, causing the penis and scrotum to droop, the puncture needle may accidentally touch the surrounding tissue. Therefore, this application provides a prostate puncture positioning auxiliary component to meet the needs. Utility Model Content
[0004] The technical problem this invention aims to solve is to provide a prostate puncture positioning auxiliary component. By setting a fixing component, the patient's buttocks can be opened, allowing the anal area to be fully exposed to the surgical field, facilitating the insertion of an ultrasound probe into the rectum to assist in the detection of lesions. At the same time, this component can replace traditional tape, effectively fixing the patient's scrotum and penis, ensuring that the puncture needle accurately reaches the target area of the prostate, reducing operational errors. Through the above settings, the problems of thick fat in the patient's buttocks hindering probe insertion and penile or scrotal prolapse hindering puncture can be solved.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A prostate biopsy positioning aid includes a bed base, a fixed seat fixedly connected to the top of the bed base, a lifting rod slidably connected inside the fixed seat, a fixed platform rotatably connected to the top of the lifting rod, a first sliding rod symmetrically slidably connected inside the fixed platform, a sliding table fixedly connected to the end of the first sliding rod, an ultrasound probe installed inside the sliding table, two second sliding rods symmetrically slidably connected inside the sliding table, and a puncture frame slidably connected to the outside of the second sliding rods; and a positioning component, which is used to open the patient's buttocks and fix the patient's penis and scrotum, and the positioning component is connected to the second sliding rods.
[0007] Optionally, each of the two second slide rods is slidably connected to a slide block, and an arc plate is rotatably connected to the side of each of the two slide blocks that are close to each other. An expansion portion is provided on the arc plate, and an extension portion is fixedly connected to the outside of the expansion portion. A connecting frame is fixedly connected between the two extension portions, and a bracket is provided on the side of the connecting frame away from the extension portion.
[0008] Optionally, a reinforcing rib is fixedly connected inside the connecting frame, and a weakening groove is provided on the frame of the connecting frame, with the weakening groove located on the side of the reinforcing rib near the extension.
[0009] Optionally, a support rod is fixedly connected between the two curved plates, and the support rod is symmetrically provided with bent portions.
[0010] Optionally, a fixing rod is fixedly connected between the two curved plates and on the side of the support rod away from the expansion portion. A pull rod is slidably connected inside the fixing rod, and one end of the expansion portion passes through the fixing rod and is fixedly connected to the support rod.
[0011] Optionally, the end of the pull rod away from the support rod is fixedly connected to a pull ring through the fixing rod.
[0012] Optionally, the pull rod has multiple slots equidistantly spaced inside, and the fixing rod has a rotatably connected card plate inside, with the bottom end of the card plate extending into the slot.
[0013] Optionally, a rotating shaft is fixedly connected to one side of the arc plate, and the rotating shaft rotates inside the slide. A fastening bolt is threaded inside the slide, and one end of the fastening bolt abuts against the rotating shaft.
[0014] Optionally, the slide block is internally threaded with a screw, and one end of the screw abuts against the second slide rod.
[0015] Optionally, a baffle is fixedly connected to one end of the fixed base, the first slide rod, and the second slide rod.
[0016] Compared with the prior art, this utility model has at least the following beneficial effects:
[0017] In the above-mentioned solution, the prostate puncture positioning auxiliary component provided in this application can expand the fat of the patient's buttocks through the set fixation component, thereby fully exposing the anal area to the surgical field, facilitating the smooth insertion of the ultrasound probe into the rectum, and thus assisting in the detection of the lesion location. At the same time, the positioning component can replace the traditional adhesive tape method to effectively fix the patient's scrotum and penis, ensuring that the puncture needle can accurately reach the target area of the prostate and greatly reducing operation errors.
[0018] The expansion joints at the front ends of the two curved plates are designed with an incline. This design facilitates their easy insertion between the patient's buttocks, laying the foundation for subsequent buttock-opening operations. The extensions on the expansion joints not only provide good support for the buttocks but also allow the connecting frames at their ends to avoid the surgical operation area, ensuring the smooth progress of the surgical procedure.
[0019] The fixed rod and the support rod work together to securely connect the two curved plates, improving the overall structural strength of the fixed components. The support rod can be stretched using the tie rod, and the extendable bending part on the support rod can flexibly adjust the distance between the two curved plates, ultimately achieving the effect of hip expansion support.
[0020] The brackets and reinforcing ribs on the connecting frame work together to fix the patient's scrotum and penis, fully exposing the puncture point in the rectum and providing great convenience for the doctor's operation. In addition, the weakening grooves on the connecting frame will bend along the arc plate when it is expanded, ensuring the fixation effect of the brackets and reinforcing ribs on the penis and scrotum.

[0036] like Figure 1 and Figure 2As shown, an embodiment of this utility model provides a prostate puncture positioning auxiliary component, including a connecting bed base 1. The connecting bed base 1 has multiple threaded holes for easy connection of the puncture equipment to the operating table. A fixing seat 101 is fixedly connected to the top of the connecting bed base 1. A lifting rod 102 is slidably connected inside the fixing seat 101. Each fixing seat 101 has threaded screws for fixing the lifting rod 102, allowing adjustment of the puncture height to accommodate patients of different sizes. A fixing platform 1 is rotatably connected to the top of the lifting rod 102. 03. The fixed platform 103 has two symmetrically sliding first slide rods 104 inside. The ends of the two first slide rods 104 are fixedly connected to a slide table 105. An ultrasound probe 106 is installed inside the slide table 105. The fixed platform 103 has multiple threaded fastening screws inside, which can fix the puncture frame 3 after angle adjustment. This allows adjustment of the angle at which the puncture or ultrasound probe 106 is inserted into the rectum. The fastening screws can also fix the first slide rods 104, ensuring that the ultrasound probe 106 is properly inserted into the rectum. To ensure stability and improve the accuracy of lesion location detection, the slide table 105 has two second slide rods 2 symmetrically slidably connected inside. A puncture frame 3 is slidably connected to the outside of the second slide rods 2. The puncture frame 3 has a fastening screw inside that works with the second slide rods 2, allowing for adjustment and fixation of the position of the puncture frame 3, thus assisting the doctor in inserting the puncture needle. A baffle is fixedly connected to one end of the fixing seat 101, the first slide rod 104, and the second slide rod 2. The baffle controls the sliding range of the lifting rod 102, the first slide rod 104, and the second slide rod 2, preventing them from separating from the main body of the device. A positioning component is used to open the patient's buttocks and fix the patient's penis and scrotum. The positioning component is connected to the second slide rod 2. The fixing component can open the patient's buttocks, allowing the anal area to be fully exposed to the surgical field, facilitating the insertion of the ultrasound probe 106 into the rectum for lesion detection. It can also fix the patient's scrotum and penis, fully exposing the puncture point in the rectum, providing convenience for the doctor's operation, ensuring the puncture needle accurately reaches the target area of the prostate, and reducing operational errors.
[0037] In this embodiment, as Figure 2 and Figure 5As shown, each of the two second slide rods 2 is slidably connected to a slide seat 414. An arc plate 4 is rotatably connected to the side of each slide seat 414 that is close to it. The arc plate 4 has an expansion section 401. The two arc plates 4 and the expansion section 401 at their front ends form a "smaller in front, larger in back" configuration, which not only facilitates installation on the two second slide rods 2, but also allows the expansion section 401 to be inclined, facilitating its insertion into the patient's buttock crease and laying the foundation for subsequent buttock-opening operations. An extension section 402 is fixedly connected to the outside of the expansion section 401, and a connecting frame 403 is fixedly connected between the two extension sections 402. The extension section 402 not only provides good support for the buttocks but also expands the position of the external connecting frame 403, thus preventing the connecting frame 403 from being manipulated during surgery. To ensure a smooth surgical procedure, a bracket 404 is provided on the side of the connecting frame 403 away from the extension 402. A reinforcing rib 405 is fixedly connected inside the connecting frame 403. A weakening groove 406 is provided on the skeleton of the connecting frame 403, and the weakening groove 406 is located on the side of the reinforcing rib 405 closer to the extension 402. The bracket 404 and the reinforcing rib 405 work together to press and fix the patient's penis and scrotum to fit against the abdomen, fully exposing the puncture point in the rectum. When the arc plate 4 expands, the connecting frame 403 will bend and deform along the position of the weakening groove 406, which can control the deformation area of the connecting frame 403 below the reinforcing rib 405 and will not affect the fixation of the penis and scrotum by the end bracket 404 and the reinforcing rib 405, ensuring the fixation effect on the penis and scrotum.
[0038] In this embodiment, as Figure 2 Figure 3 , Figure 5 and Figure 6As shown, a support rod 408 is fixedly connected between the two curved plates 4. The support rod 408 is made of elastic material and has symmetrically arranged bending portions 409. The bending portions 409 can provide support for the deformation of the support rod 408. When the support rod 408 is stretched and deformed, the bending degree of the bending portion 409 decreases, thereby increasing the overall length of the support rod 408. This causes the two curved plates 4 to move away from each other, allowing the expansion portion 401 to open the patient's buttocks, thus fully exposing the patient's anus and facilitating the insertion of the ultrasound probe 106 into the rectum. A fixing rod 407 is fixedly connected between the two curved plates 4 and on the side of the support rod 408 away from the expansion portion 401. A pull rod 410 is slidably connected inside the fixing rod 407. One end of the expansion portion 401 passes through the fixing rod 407 and is fixedly connected to the support rod 408. The end of the pull rod 410 away from the support rod 408 passes through the fixing rod 407 and is fixedly connected to a pull ring 412. 412 drives the pull rod 410 to slide inside the fixed rod 407, which allows it to stretch the support rod 408. Combined with the extendable bending part 409 on the support rod 408, the distance between the two curved plates 4 can be flexibly adjusted, ultimately achieving the effect of expanding the support part 401 to expand the buttocks. The pull rod 410 has multiple slots 411 evenly spaced inside. The fixed rod 407 is rotatably connected to a plate 413, and the bottom end of the plate 413 extends into the slot 411. When the expansion part 401 moves, it drives the plate 413 to rotate. When the plate 413 is inserted into the slot 411, it abuts against the inner wall of the slot 411, thus preventing the pull rod 410 from moving in the opposite direction, thereby fixing the pull rod 410 and ensuring the stability of the expansion part 401 in expanding the buttocks. At the same time, the bottom of the slot 411 is designed with a slope to ensure that the pull rod 410 moves towards the plate 413 without obstruction.
[0039] In this embodiment, as Figure 2 and Figure 4 As shown, a rotating shaft is fixedly connected to one side of the arc plate 4, and the rotating shaft rotates inside the slide 414. A fastening bolt 415 is threaded inside the slide 414, and one end of the fastening bolt 415 abuts against the rotating shaft. Through this design, the angle of the positioning component can be adjusted and fixed, which can adapt to the usage requirements of the positioning component at different angles. A screw is threaded inside the slide 414, and one end of the screw abuts against the second slide rod 2. The screw inside the slide 414 that cooperates with the second slide rod 2 can fix the lateral position of the positioning component, control the fit between the positioning component and the patient's body, and improve the accuracy of auxiliary positioning.
[0040] The working principle provided by this utility model is as follows:
[0041] When using this positioning aid, first connect the bed seat 1 to the operating table. Adjust the height and angle of the fixing platform 103 according to the patient's anal position to accommodate the insertion of the ultrasound probe 106. Next, push the second slide bar 2 to move the positioning aid closer to the patient's buttocks. Then adjust the angle of the positioning aid to better fit the patient's body. Afterward, push the two curved plates 4 to move the slide seat 414 on the second slide bar 2, finely adjusting the positioning aid so that the expansion portion 401 at the front end of the curved plate 4 is inserted into the patient's buttock groove. Simultaneously, the doctor manually presses the patient's scrotum and penis against the abdomen. At this time, the bracket 404 at the top of the connecting frame 403 and... The reinforcing rib 405 presses and fixes the penis and scrotum, clearly exposing the puncture site. Then, the pull ring 412 moves the pull rod 410 to stretch the support rod 408. At this time, the support rod 408 deforms along the bend 409, thereby extending the overall length of the support rod 408, expanding the arc plate 4 and the expansion part 401, and thus opening the patient's buttocks. During this process, the arc plate 4 drives the extension part 402 and the connecting frame 403 to expand outward. Since the connecting frame 403 has a weakening groove 406 and a reinforcing rib 405 above the weakening groove 406, the deformation area of the connecting frame 403 can be controlled below the reinforcing rib 405. To ensure the fixation effect of the bracket 404 and reinforcing rib 405 on the penis and scrotum, the movement of the pull rod 410 will drive the clamping plate 413 to rotate. After the expansion is completed, the movement of the pull rod 410 stops. At this time, the clamping plate 413 rotates downward and falls into the clamping groove 411, which can resist the pull rod 410, thereby fixing the position of the fixed pull rod 410 and the support rod 408 and ensuring the stability of the expansion. Then, the slide table 105 is pushed to move. Under the doctor's operation, the ultrasound probe 106 is inserted into the patient's rectum to perform ultrasound detection on the location of the prostate lesion. Then, the puncture frame 3 is pushed to slide on the second slide rod 2 to fit the puncture site. According to the location of the lesion, the appropriate treatment is given. The puncture procedure is performed through the puncture hole on the puncture frame 3. After the puncture is completed, the second slide bar 2 is pulled away from the patient to separate the component from the patient. To reset the arc plate 4 and the expansion part 401, the pull rod 410 is pulled forward. When the retaining plate 413 is removed from the retaining groove 411, the retaining plate 413 is moved, and then the pulling force on the pull rod 410 is released. At this time, the pull rod 410 will move in the opposite direction under the action of the support rod 408, so that the support rod 408 and the bending part 409 return to their original shape. After the shape of the support rod 408 is restored, the arc plate 4 and the expansion part 401 can be reset to their initial state for cleaning and use in subsequent surgeries.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0043] The above description is only a preferred embodiment of the present utility model.
