Postoperative protective device for urology

Abstract

This invention belongs to the field of medical device technology and relates to a postoperative protective device for urological surgery. The invention includes an elastic band, a pad, and a connecting tube. Both the pad and the connecting tube have semi-circular cross-sections. Two pads are detachably connected via a connector, and each pad is fixedly connected to an elastic band. Each pad is also fixedly connected to a connecting tube, and each connecting tube has two symmetrically formed transverse grooves on its inner wall, parallel to the axis of the connecting tube. Multiple elastic restraint bands are slidably arranged between the two transverse grooves. When the patient's penis is erect, the penis moves the elastic restraint bands, keeping the contact position between the penis and the elastic restraint bands constant. This reduces discomfort caused by the movement of the penis relative to the elastic restraint bands and avoids friction between the elastic restraint bands and the wound on the penis, thus promoting patient recovery. Simultaneously, the oblique grooves bring the two ends of the elastic restraint bands closer together, preventing the clamping force of the elastic restraint bands on the penis from increasing and causing discomfort to the patient.

Description

Technical Field

[0001] This invention belongs to the field of medical device technology and relates to a postoperative protection device for urology. Background Technology

[0002] Pediatric urology is a medical specialty that treats diseases of the urinary system in children, including but not limited to congenital urinary tract malformations, urinary tract infections, urinary tract tumors, hypospadias, hydronephrosis, bladder exstrophy, and male genital malformations. In pediatric urology, some children require penile correction surgery for certain congenital or acquired problems. Because children are active and energetic, friction between the surgical wound and clothing can easily occur after surgery, causing pain and hindering wound healing. Therefore, to avoid pain caused by friction between clothing and the wound, the penis needs to be protected to facilitate the patient's recovery.

[0003] Some wearable protective devices can prevent the penis from rubbing against clothing, thus providing protection. However, after surgery, the penis may become erect due to pain, which can cause the penis to move relative to the protective device, resulting in friction between the inner wall of the device and the penis. This can cause discomfort to the patient and also hinder wound healing.

[0004] To address the above problems, this invention proposes a postoperative protection device for urological surgery. Summary of the Invention

[0005] To address the problems existing in the background art, the present invention proposes a postoperative protection device for urology.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] Postoperative protective devices for urology include elastic bandages, pads, and connecting tubes;

[0008] Both the pad and the connecting pipe have semi-circular cross-sections. There are two pads, which are detachably connected by a connector. Each pad is fixedly connected with an elastic strap.

[0009] Each pad is fixedly connected to a connecting pipe at its left end. Each connecting pipe has two symmetrically arranged transverse grooves on its inner wall, which are parallel to the axis of the connecting pipe. Multiple elastic limiting bands are slidably arranged between the two transverse grooves. Each elastic limiting band has a slider fixed at both ends, and the slider is slidably arranged in the corresponding transverse groove.

[0010] Furthermore, each transverse groove has multiple inclined grooves along the axial direction of the connecting pipe on its inner wall. The end of the inclined groove away from the pad plate is inclined towards the inner wall of the connecting pipe. In two adjacent inclined grooves in the same transverse groove, the length of the left inclined groove is greater than the length of the right inclined groove, and the inclination angle of the left inclined groove is less than the inclination angle of the right inclined groove. Multiple inclined grooves correspond one-to-one with multiple sliders, and each slider has a protrusion that is slidably set in the corresponding inclined groove.

[0011] Furthermore, a threaded groove block is fixedly connected to the left end of the pad. The threaded groove block is located on the outside of the connecting pipe, and a sleeve is threadedly fitted onto the threaded groove block.

[0012] Furthermore, the sleeve is provided with multiple vent holes.

[0013] Furthermore, the connector includes bolts and nuts; both washers are fixedly connected to fixing blocks, and the fixing blocks have bolt holes that mate with the bolts, and the nuts mate with the bolts; the two washers are connected by bolts and nuts.

[0014] Furthermore, a rubber pad is provided at the right end of the pad.

[0015] Furthermore, a first silicone block is provided on the inner wall of the pad.

[0016] Furthermore, a second silicone block is provided on both sides of the connecting tube, and the second silicone block is located outside the elastic limiting band.

[0017] Compared with the prior art, the present invention has the following beneficial effects: when the patient's penis is erect, the penis moves the elastic limiting band, so that the contact position between the penis and the elastic limiting band remains unchanged. This reduces the discomfort caused by the movement of the penis relative to the elastic limiting band, avoids the elastic limiting band rubbing against the wound on the penis, and is conducive to the patient's recovery.

[0018] Meanwhile, the inclined groove design brings the two ends of the elastic restraint band closer together, preventing the elastic restraint band from increasing its clamping force on the penis and causing discomfort to the patient. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figures 1-8 As shown, the technical solution adopted in this invention is as follows: A postoperative protective device for urology includes an elastic bandage 1, a pad 3, and a connecting tube 10. Both the pad 3 and the connecting tube 10 have semi-circular cross-sections. There are two pads 3, which are detachably connected by a connector. Specifically, the connector includes a bolt 4 and a nut 5. A fixing block is fixed to each pad 3, and each fixing block has a bolt hole adapted to the bolt 4. The bolt 4 and nut 5 cooperate. The two fixing blocks are fixedly connected by the bolt 4 and nut 5.

[0030] Each pad 3 has a connecting tube 10 coaxially fixed to its left end. When two pads 3 are connected by a connector, the space between the two pads 3 and the space between the two connecting tubes 10 forms a placement cavity for placing the patient's penis.

[0031] A rubber pad 2 is provided at the right end of the pad 3. The rubber pad 2 comes into contact with the patient's skin to improve the patient's comfort.

[0032] A first silicone block 9 is fixed on the inner circumference of the pad 3. The first silicone block 9 comes into contact with the patient's body, improving the patient's comfort.

[0033] Two transverse grooves 13 are symmetrically formed on the inner wall of each connecting tube 10, and the transverse grooves 13 are parallel to the axis of the connecting tube 10. An elastic limiting band 12 is slidably connected between the two transverse grooves 13. A slider is fixedly connected to both ends of each elastic limiting band 12, and the slider is slidably disposed in the corresponding transverse groove 13. When the patient's penis becomes erect due to pain, the penis moves the elastic limiting band 12, so that the contact position between the elastic limiting band 12 and the penis remains unchanged, thereby preventing the elastic limiting band 12 from moving on the penis and causing discomfort to the patient.

[0034] Multiple inclined grooves are formed on the inner wall of each transverse groove 13 along the axial direction of the connecting pipe 10. The end of the inclined groove away from the pad 3 is inclined towards the inner wall of the connecting pipe 10. The multiple inclined grooves correspond one-to-one with multiple sliders. Each slider is fixedly connected with a protrusion, which is slidably arranged in the corresponding inclined groove.

[0035] Within each transverse groove 13, between two adjacent inclined grooves, the length of the left inclined groove is greater than the length of the right inclined groove, and the inclination angle of the left inclined groove is less than the inclination angle of the right inclined groove.

[0036] In this embodiment, each transverse groove 13 has three inclined grooves. For ease of description, the three inclined grooves are named the first inclined groove 15, the second inclined groove 17, and the third inclined groove 19, respectively. The corresponding three sliders are named the first slider 14, the second slider 16, and the third slider 18, respectively. The three protrusions are named the first protrusion 20, the second protrusion 21, and the third protrusion 22, respectively. The first protrusion 20 is slidably disposed in the first inclined groove 15 and fixedly connected to the first slider 14. The second protrusion 21 is slidably disposed in the second inclined groove 17 and fixedly connected to the second slider 16. The third protrusion 22 is slidably disposed in the third inclined groove 19 and fixedly connected to the third slider 18. The length of the third inclined groove 19 is greater than the length of the second inclined groove 17, and the length of the second inclined groove 17 is greater than the length of the first inclined groove 15. The inclination angle of the third inclined groove 19 is less than the inclination angle of the second inclined groove 17, and the inclination angle of the second inclined groove 17 is less than the inclination angle of the first inclined groove 15.

[0037] Each connecting tube 10 has a second silicone block 11 fixedly installed on both sides of its inner wall, located outside the elastic limiting band 12. When the patient's penis is inside the placement cavity, it contacts the elastic limiting band 12 on both sides, which clamps and fixes it. The second silicone block 11 prevents the patient's penis from directly contacting the connecting tube 10, improving patient comfort.

[0038] Each pad 3 has a threaded groove block 6 coaxially fixedly connected to its left end, and the threaded groove block 6 is located on the outside of the connecting pipe 10. When two pads 3 are connected together, the two threaded groove blocks 6 are in contact and engaged. The threaded groove block 6 is threadedly engaged with a sleeve 7, and the right end of the sleeve 7 is arc-shaped. The sleeve 7 has multiple vent holes 8.

[0039] Each pad 3 is connected to an elastic strap 1, which secures the device to the patient.

[0040] Working principle: Initially, the first protrusion 20 is located at the right end of the first inclined groove 15, the second protrusion 21 is located at the right end of the second inclined groove 17, and the third protrusion 22 is located at the right end of the third inclined groove 19. There is a gap between adjacent elastic limiting bands 12.

[0041] In use, two pads 3 are placed on either side of the patient's penis, and then connected by bolts 4 and nuts 5. The two pads 3 and the two connecting tubes 10 form a placement cavity, within which the patient's penis is positioned between the elastic restraint bands 12 on both sides, preventing the penis from contacting the connecting tubes 10 and causing discomfort. The elastic restraint bands 12 clamp and fix the patient's penis, and exert a certain clamping force on the penis.

[0042] The cannula 7 is then installed onto the threaded groove block 6. Medical personnel can adjust the length of the cannula 7 screwed into the threaded groove block 6 according to the length of the patient's penis. The vent hole 8 ensures that the cannula 7 provides good ventilation while protecting the patient's penis, which is beneficial for the patient's recovery.

[0043] Then, the two elastic straps 1 are tied around the patient's waist to secure the device.

[0044] When the patient's penis enlarges and lengthens due to painful erection, the elastic restraint band 12 exerts a certain clamping force on the penis, creating friction between the penis and the elastic restraint band 12. As the penis lengthens, it causes the elastic restraint band 12 to move to the left, and the first slider 14, second slider 16, and third slider 18 also move to the left. During this leftward movement, the first slider 14 moves faster than the second slider 16, and the second slider 16 moves faster than the third slider 18. This ensures that the contact position between the elastic restraint band 12 and the penis remains unchanged as the penis lengthens, thus preventing relative movement between the elastic restraint band 12 and the penis that could cause friction and discomfort to the patient, and avoiding friction between the elastic restraint band 12 and the penile wound, which could hinder wound healing.

[0045] When the first slider 14, the second slider 16, and the third slider 18 move to the left, the first protrusion 20 moves to the left along the first inclined groove 15, the second protrusion 21 moves to the left along the second inclined groove 17, and the third protrusion 22 moves to the left along the third inclined groove 19. This causes the two ends of the elastic limiting band 12 to move closer together. Since the outer diameter of the penis increases as it lengthens, the close proximity of the two ends of the elastic limiting band 12 ensures that the clamping force of the elastic limiting band 12 on the penis does not increase, thus preventing discomfort to the patient.

[0046] Therefore, the inclination angles of the third inclined groove 19, the second inclined groove 17 and the first inclined groove 15 are reasonably set so that the clamping force of the elastic limiting band 12 on the penis is kept within a certain range.

[0047] As the patient's penis gradually returns to normal, the shortening of the penis causes the elastic limiting band 12 to move to the right, maintaining the contact position between the elastic limiting band 12 and the penis. The first slider 14, the second slider 16, and the third slider 18 move to the right, the first protrusion 20 moves to the right along the first inclined groove 15, the second protrusion 21 moves to the right along the second inclined groove 17, and the third protrusion 22 moves to the right along the third inclined groove 19. The two ends of the elastic limiting band 12 move away from each other, thereby maintaining the clamping of the penis.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
