Description

Technical Field

[0001] The invention belongs to the field of urinary system surgical instruments, and in particular relates to a visualized bladder puncture, fistula and drainage device. Background Art

[0002] Cystostomy and drainage is a treatment method that uses percutaneous puncture to establish a temporary or long-term urine drainage channel in the bladder. Ultrasound-guided bladder puncture and endoscopic bladder puncture are two commonly used visualization puncture methods. Because the use of an endoscope requires an additional puncture hole, ultrasound-guided bladder puncture is more commonly used.

[0003] The existing patent with application number 201921794172.5 discloses a non-destructive bladder fistula kit, including a fistula tube body, a guide head and a puncture needle, the puncture needle passes through the fistula tube body, the guide head is fixed at the bottom of the fistula tube body, the puncture needle is passed through the fistula tube body from the top opening of the fistula tube body and passes through the bottom opening of the fistula tube body through the guide head, the guide head is divided into a rectangular hole guide head and a round hole guide head, the puncture needle is divided into a fixed head puncture needle and a non-invasive puncture needle, the fixed head puncture needle is installed in the fistula tube body in cooperation with the rectangular hole guide head, and the round hole guide head is installed in the fistula tube body in cooperation with the non-invasive puncture needle.

[0004] The prior art has the following problems:

[0005] In order to avoid causing additional wounds, an incision is made in the epidermis, and the bladder is punctured with a puncture needle under ultrasound positioning. This will result in the inability to effectively avoid the vascular area on the surface of the bladder during puncture. When urinary retention occurs, the urine in the bladder will produce a large number of bacteria. When the vascular area on the surface of the bladder is damaged, the urine that exudes during puncture will contaminate the blood and cause infection. Summary of the invention

[0006] The present invention provides a visualized bladder puncture and fistula drainage device, which can solve the technical problem that the visualized puncture in the prior art cannot effectively avoid the blood vessel area on the surface of the bladder without causing additional wounds, thereby causing infection.

[0007] In order to achieve the above object, the present invention is implemented by the following technical solutions:

[0008] The present application provides a visualized bladder puncture fistula drainage device, which includes a puncture sheath, a visualized puncture assembly, a puncture needle core, an image acquisition end and a display screen, wherein the puncture sheath is used to be inserted into the bladder surface through an incision to isolate an operation channel; the visualized puncture assembly is connected to the puncture sheath; the puncture needle core is connected to one end of the visualized puncture assembly, and the outer side of the puncture needle core is wrapped with an optical fiber integration body, and the end of the optical fiber integration body facing the needle tip of the puncture needle core is tapered; the image acquisition end is connected to the inner side of the visualized puncture assembly, and the image acquisition end is optically coupled with the end of the optical fiber integration body away from the needle tip of the puncture needle core; the display screen is connected to the end of the visualized puncture assembly away from the puncture needle core, and the display screen is communicatively connected to the image acquisition end, and the image acquisition end acquires an image of the needle tip end of the puncture needle core through the optical fiber integration body and transmits it to the display screen.

[0009] Through the above technical solution, an optical fiber assembly is used as a light-transmitting body to combine the image acquisition end and the puncture needle core. After the puncture and endoscope functions are integrated, the additional opening of an endoscope penetration port is avoided, and the tissue image at the front end of the puncture needle core can be viewed in real time through the display screen, thereby avoiding the blood vessel area during puncture and reducing the probability of infection.

[0010] In the present invention, the above-mentioned visualized bladder puncture fistula drainage device also includes a negative pressure chamber, a negative pressure generating bag and a negative pressure adsorption end. The negative pressure chamber is arranged on the outside of the puncture sheath; the negative pressure generating bag is connected to the outside of the negative pressure chamber, and the negative pressure generating bag forms a negative pressure in the negative pressure chamber through an external air source; the negative pressure adsorption end is arranged at one end of the negative pressure chamber facing the puncture needle core, and the negative pressure adsorption end is provided with a plurality of adsorption holes. When the negative pressure chamber forms a negative pressure, the adsorption holes are used to adsorb the outer epidermis of the bladder.

[0011] Through the above technical solution, the negative pressure adsorption end is used to adsorb the bladder epidermal area to be punctured, so as to fix the relative position of the bladder and the puncture sheath, thereby avoiding compression of the bladder during puncture. At the same time, because only one side of the bladder wall is adsorbed, penetrating damage to the bladder during puncture can also be avoided, thereby improving the accuracy and safety of bladder puncture.

[0012] In the present invention, the above-mentioned visualized bladder puncture fistula drainage device also includes multiple pieces of nanosilver drainage cloth, which are arranged on the outside of the negative pressure cavity. The nanosilver drainage cloth is attached to the inside of the epidermal incision as the puncture sheath is inserted.

[0013] Through the above technical solution, the nano-drainage cloth is attached to the inner side of the epidermal incision as the puncture sheath passes through the epidermis, which can reduce the friction between the puncture sheath and the skin tissue and reduce contusion. At the same time, after the nano-silver drainage cloth covers the wound, it can effectively drain the tissue fluid in the wound, which is beneficial to keep the wound clean and can also play an antibacterial and anti-inflammatory role.

[0014] In the present invention, the above-mentioned visualized bladder puncture fistula drainage device further comprises a plurality of lubrication grooves, which are opened on the outside of the negative pressure cavity along the axial direction of the puncture sheath, and the lubrication grooves are filled with lubricant.

[0015] Through the above technical solution, the lubricant is stored in the lubrication groove. After the puncture sheath is separated from the nanosilver drainage cloth, the lubricant can continue to maintain the lubricity of the puncture sheath and subcutaneous tissues such as fat, thereby reducing the contusion of the puncture sheath to the internal tissue.

[0016] In the present invention, the above-mentioned visualized bladder puncture fistula drainage device also includes a scale line, which is arranged on the outer wall of the negative pressure cavity, and the insertion depth of the puncture sheath is obtained according to the scale of the scale line immersed in the epidermal incision.

[0017] Through the above technical solution, the graduation line can be used to identify the insertion depth of the puncture sheath after the negative pressure adsorption end at the end of the puncture sheath is adsorbed and positioned on the bladder wall, thereby facilitating the selection of equipment of appropriate length during subsequent operations.

[0018] In the present invention, the above-mentioned visualized bladder puncture fistula drainage device also includes a drainage tube, a first airbag and a second airbag, the drainage tube is inserted into the puncture sheath; the first airbag ring is arranged in the middle of the drainage tube, and the first airbag abuts against the outer side of the epidermal incision after being inflated; the second airbag ring is arranged at one end of the drainage tube inserted into the bladder, and the second airbag abuts against the inner wall of the bladder after being inflated.

[0019] Through the above technical solution, two air bags are positioned on the inner wall of the bladder and the outer side of the epidermal incision at the same time, thereby improving the positioning stability of the drainage tube.

[0020] In the present invention, the first airbag and the second airbag are in communication with each other.

[0021] Through the above technical solution, the two airbags are connected, and when the bladder contracts, the second airbag can be compressed at the same time to press the gas into the first airbag, thereby reducing the pressure exerted by the second airbag on the bladder.

[0039] Example:

[0040] Please refer to Figures 1 to 11 , Figures 1 to 11 An embodiment of the present application is shown.

[0041] This embodiment provides a visual bladder puncture and fistula drainage device, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a puncture sheath, a visualized puncture assembly 2, a puncture needle core 204, an image acquisition end 203 and a display screen 201. The puncture sheath is used to be inserted into the bladder surface through the incision to isolate the operation channel; the visualized puncture assembly 2 is connected to the puncture sheath; the puncture needle core 204 is connected to one end of the visualized puncture assembly 2, as shown in FIG. Figure 6 As shown, the outer side of the puncture needle core 204 is wrapped with an optical fiber assembly 205, and the end of the optical fiber assembly 205 facing the needle tip of the puncture needle core 204 is tapered; the image acquisition end 203 is connected to the inner side of the visualization puncture component 2, and the image acquisition end 203 is optically coupled with the end of the optical fiber assembly 205 away from the needle tip of the puncture needle core 204; the display screen 201 is connected to the end of the visualization puncture component 2 away from the puncture needle core 204, and the display screen 201 is communicatively connected with the image acquisition end 203, and the image acquisition end 203 acquires the image of the needle tip end of the puncture needle core 204 through the optical fiber assembly 205 and transmits it to the display screen 201.

[0042] When used, a scalpel is used to make an incision at the puncture site determined after ultrasound examination, and then the puncture sheath is inserted. Figure 2 and Figure 3 As shown, the bottom of the puncture sheath is flat to prevent the puncture sheath from accidentally injuring other organs. The outer end of the puncture sheath is provided with an operating wing 103 to facilitate the application of pressure to pass through the fat layer and other body tissues to reach the outside of the bladder. After the puncture sheath is inserted, the visualization puncture assembly 2 is inserted into the puncture sheath lumen 105, as shown in FIG. Figure 4 As shown, the displacement of the visualized puncture component 2 is controlled by the operating handle 202, and the optical fiber assembly 205 is formed by gluing together a number of tiny optical fibers. The two end faces of each optical fiber are parallel, thereby obtaining a good light conduction effect, and multiple optical fibers are arranged in a stepped manner to form a cone to reduce the resistance to insertion. For ease of assembly, the puncture needle core 204 and the optical fiber assembly 205 are fixed into the fixing ring 206 after completion of adhesion, and then the image acquisition end 203 is inserted into the other end of the fixing ring 206 to complete the optical coupling, and then the front end image of the puncture needle core 204 can be intuitively observed through the display screen 201, thereby avoiding the vascular area on the surface of the bladder.

[0043] It should be noted that in some primary medical units without ultrasound or endoscopes, and when emergency measures are needed in some field locations, the integrated visualization puncture assembly 2 can be used to directly perform safer and more reliable puncture drainage. In exemplary use, a built-in battery is used to power the display screen 201 and the image acquisition terminal 203; the outer ring of the image acquisition terminal 203 is integrated with a ring-shaped light source, and the light source transmits light to the outside through the outer ring optical fiber of the optical fiber assembly 205 to provide lighting function.

[0044] Through the above technical solution, the optical fiber assembly 205 is used as a light-transmitting body to combine the image acquisition end 203 and the puncture needle core 204. After the puncture and endoscope functions are integrated, the additional opening of the endoscope penetration port is avoided, and the tissue image at the front end of the puncture needle core 204 can be viewed in real time through the display screen 201, thereby avoiding the blood vessel area during puncture and reducing the probability of infection.

[0045] As a preferred implementation method, Figures 2 to 5 As shown, the above-mentioned visualized bladder puncture fistula drainage device also includes a negative pressure chamber 104, a negative pressure generating bag 101 and a negative pressure adsorption end 102. The negative pressure chamber 104 is arranged on the outside of the puncture sheath; the negative pressure generating bag 101 is connected to the outside of the negative pressure chamber 104, and the negative pressure generating bag 101 forms a negative pressure in the negative pressure chamber 104 through an external air source; the negative pressure adsorption end 102 is arranged at one end of the negative pressure chamber 104 facing the puncture needle core 204, and the negative pressure adsorption end 102 is provided with a plurality of adsorption holes 1021. When the negative pressure chamber 104 forms a negative pressure, the adsorption holes 1021 are used to adsorb the outer skin of the bladder.

[0046] When in use, the gas source of the hospital's central air supply is used to connect the negative pressure generator, and the negative pressure generator is connected to the negative pressure generating bag 101. The negative pressure generator can be turned on to generate negative pressure in the negative pressure chamber 104. This is because the principle of the negative pressure generator is that the high-speed flowing gas forms a low pressure at the tube mouth, and then the negative pressure formed by the gas in the tube is discharged. Therefore, it will not produce a suction force on the bladder epidermis that is sufficient to cause damage to it. After the puncture position is determined by the visual puncture component 2, the bladder epidermis is adsorbed by negative pressure, and the relative position of the bladder epidermis and the puncture sheath is fixed to a certain extent. Then, the operating handle 202 can be pushed downward to puncture the bladder epidermis using the puncture needle core 204, and then the tapered optical fiber assembly 205 further expands the puncture port to facilitate the subsequent insertion of the drainage tube 501.

[0047] Through the above technical solution, the negative pressure adsorption end 102 is used to adsorb the bladder epidermal area to be punctured, so as to fix the relative position of the bladder and the puncture sheath, thereby avoiding compression of the bladder during puncture. At the same time, because only one side of the bladder wall is adsorbed, penetrating damage to the bladder during puncture can also be avoided, thereby improving the accuracy and safety of bladder puncture.

[0048] As a preferred implementation method, Figure 1 , Figure 7 , Fig.10 and Fig.11As shown, the above-mentioned visualized bladder puncture fistula drainage device also includes four pieces of nanosilver drainage cloth 3, which are arranged in a ring on the outside of the negative pressure cavity 104. The side of the nanosilver drainage cloth 3 facing the negative pressure cavity 104 is attached with medical pressure-sensitive adhesive for bonding with the negative pressure cavity 104. The nanosilver drainage cloth 3 is separated from the outside of the negative pressure cavity 104 as the puncture sheath is inserted, and the medical pressure-sensitive adhesive adheres the nanosilver drainage cloth 3 to the inside of the epidermal incision.

[0049] When using, Figure 1 As shown, the lower end surface of the nanosilver drainage cloth 3 is folded upward during packaging. After removal, the folded end of the nanosilver drainage cloth 3 is laid flat, and then pressed on the skin surface with tweezers or hands, and then Fig.10 and Fig.11 As shown, as the puncture sheath goes deeper, the nanosilver drainage cloth 3 gradually fits around the incision opened in the epidermal model 6.

[0050] Through the above technical solution, the nano-drainage cloth is attached to the inner side of the epidermal incision as the puncture sheath passes through the epidermis, which can reduce the friction between the puncture sheath and the skin tissue and reduce contusion. At the same time, after the nano-silver drainage cloth 3 covers the wound, it effectively drains the tissue fluid in the wound, which is beneficial to keep the wound clean and can also play an antibacterial and anti-inflammatory role.

[0051] As a preferred implementation method, Figures 7 to 9 As shown, the above-mentioned visualized bladder puncture fistula drainage device also includes a plurality of lubrication grooves 401, which are opened on the outside of the negative pressure cavity 104 along the axial direction of the puncture sheath, and the lubrication grooves 401 are filled with lubricants, and an exemplary lubricant is a polyethylene glycol medical lubricant.

[0052] During use, as the nanosilver drainage cloth 3 is separated, the outer wall of the negative pressure chamber 104 will gradually come into contact and rub against the tissue in the body, and the pre-filled lubricant will slide from the lubrication groove 401 to the outer wall of the negative pressure chamber 104 and the tissue for lubrication.

[0053] Through the above technical solution, the lubricant is stored in the lubrication groove 401. After the puncture sheath is separated from the nanosilver drainage cloth 3, the lubricant can continue to maintain the lubricity of the puncture sheath and subcutaneous tissues such as fat, thereby reducing the contusion of the puncture sheath to the internal tissue.

[0054] As a preferred implementation method, Fig. 9 As shown, the above-mentioned visualized bladder puncture fistula drainage device also includes a scale line 402, and the scale line 402 is set on the outer wall of the negative pressure chamber 104. The insertion depth of the puncture sheath is obtained according to the scale of the scale line 402 immersed in the epidermal incision, and then when selecting the double-balloon drainage tube 501, the drainage tube 501 with different balloon spacing models can be selected.

[0055] Through the above technical solution, the scale line 402 can be used to identify the insertion depth of the puncture sheath after the negative pressure adsorption end 102 at the end of the puncture sheath is adsorbed and positioned on the bladder wall, thereby facilitating the selection of an appropriate length of equipment during subsequent operations.

[0056] As a preferred implementation method, Fig.10 As shown, the above-mentioned visualized bladder puncture fistula drainage device also includes a drainage tube 501, a first airbag 503 and a second airbag 504. The drainage tube 501 is inserted into the puncture sheath; the first airbag 503 is arranged in the middle of the drainage tube 501, and the first airbag 503 abuts against the outer side of the epidermal incision after being inflated; the second airbag 504 is arranged in the middle of the drainage tube 501, and the second airbag 504 abuts against the inner wall of the bladder after being inflated.

[0057] When using, Fig.10 As shown, for example, because the negative pressure adsorption end 102 is used to adsorb and position the bladder model 7, the step of inserting a guide wire can be saved when inserting the drainage tube 501.

[0058] Through the above technical solution, two air bags are positioned on the inner wall of the bladder and the outer side of the epidermal incision at the same time, thereby improving the positioning stability of the drainage tube 501.

[0059] As a preferred embodiment, the first airbag 503 and the second airbag 504 are connected.

[0060] During use, in order to facilitate the removal of the puncture sheath, when gas is input through the injection tube 502, the first airbag 503 is compressed by the puncture sheath lumen 105, which will cause its expanded volume to be smaller than the second airbag 504. The excess gas is input into the second airbag 504 through the connected pipe. When the puncture sheath is removed, the internal air pressure of the two airbags is balanced through the pipe and restored to the same pressure. When the patient moves or the bladder spasms and contracts, the second airbag 504 will be squeezed in the same way. If the second airbag 504 is an independent airbag at this time, there is a risk of bladder tearing. Because the second airbag 504 is connected to the first airbag 503, after the second airbag 504 is compressed, the excess gas will enter the first airbag 503, thereby avoiding bladder tearing.

[0061] Through the above technical solution, the two airbags are connected, and when the bladder contracts, the second airbag 504 can be compressed at the same time to press the gas into the first airbag 503, thereby reducing the pressure exerted by the second airbag 504 on the bladder.

[0062] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope of the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
