Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a renal puncture fistula drainage device. Background Art

[0002] In the current surgical field, after establishing a percutaneous renal channel through minimally invasive, laparoscopic or open surgery, surgical treatment of upper urinary tract diseases, especially upper urinary tract stones, generally requires routine placement of a nephrostomy drainage tube.

[0003] For example, an easy-to-use adhesive fistula drainage tube with announcement number CN212547907U is used to insert the drainage tube from the patient's body to the patient's lesion site. The fixing piece is used to fix the drainage tube and provide a convenient installation point for the connecting mechanism. The tape fixing device is used to quickly disassemble and assemble the medical tape. The medical tape is attached to the patient's body surface skin. The tape fixing device is fixed to the patient's body surface skin by the medical tape. Multiple tape fixing devices are evenly distributed around the same fixing device and each tape fixing device is fixedly connected to the fixing device by the connecting mechanism, so that the fixing device is fixed to the patient's body surface, thereby making the drainage tube immovable. However, in actual use, the drainage tube can also be directly fixed to the patient's skin at the puncture site by medical tape. However, direct fixation with tape requires a larger area of ​​tape to ensure the reliability of fixation. After being fixed with a large area of ​​tape, the patient's skin is covered by the tape, and the air permeability is poor, which can easily cause discomfort to the patient. The comparative document uses a tape fastener to fix the drainage tube, but the tape fastener is connected to the fixing piece through a connecting structure, and the fixing piece is fixed to the drainage tube through a hoop. At present, most medical drainage tubes are made of silicone material. The drainage tube itself is relatively soft. The fixing piece is fixed by a hoop. After the hoop is tightened to ensure the fixing effect, it is easy to compress the drainage tube. Since the drainage tube material is relatively soft, it will compress the drainage tube to deform. Most of the fluids drained by the patient will contain blood, urine or pus. After the drainage tube is compressed, the diameter of the fluid passing through is reduced. When the pus with poor fluidity is drained, the pus does not pass smoothly when passing through the compressed part of the drainage tube, which will cause drainage blockage. There are certain usage defects.

[0004] Therefore, we propose a renal puncture fistula drainage device to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to provide a renal puncture fistula drainage device to solve the problem that the drainage tube can be directly fixed on the skin of the patient's puncture site by medical tape. However, the direct fixation with tape requires a large area of ​​tape to ensure the reliability of fixation. After the large area of ​​tape is fixed, the patient's skin is covered by the tape, and the air permeability is poor, which is easy to cause discomfort to the patient. The comparative document uses a tape fixer to fix the drainage tube, but the tape fixer is connected to the fixing piece by a connecting structure, and the fixing piece is fixed by a hoop. Fixed on the drainage tube. Currently, most medical drainage tubes are made of silicone material. The drainage tube itself is relatively soft. It is fixed to the fixing part by a hoop. After the hoop is tightened to ensure the fixing effect, it is easy to compress the drainage tube. Since the drainage tube material is relatively soft, it will compress the drainage tube to deform. Most of the fluids drained by patients will contain blood, urine or pus. After the drainage tube is compressed, the diameter of the fluid passing through is reduced. When draining pus with poor fluidity, the pus does not pass smoothly when passing through the compressed part of the drainage tube, which will cause drainage blockage.

At the same time, support frames are symmetrically installed on one side of the fixing plate below the two through holes, and a rotating wheel is rotatably connected between the two support frames.

[0016] By adopting the above technical solution, when the drainage tube is removed, it is convenient to pull and stretch the positioning rod to disengage from the positioning groove, so that the fixing ring loses its limit, and the fixing tape can be easily removed.

[0017] Preferably, a limit block is fixedly installed on the other side of the two through holes outside the pull rope.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: the renal puncture fistula drainage device is provided with a fixing assembly on the outside of the drainage tube, so that when the drainage tube is fixed, a plurality of fixing rods can be reliably fixed by a fixing tape, and the fixing rods will not compress the drainage tube after being fixed, so that deformation of the drainage tube can be avoided, and discomfort to the patient will not be caused, thereby improving practicality;

[0026] 1. A fixing component is provided on the outside of the drainage tube. When fixing the drainage tube, the installation ring is put on the outside of the drainage tube. When fixing the installation ring, the connecting rope is in a relaxed state, and the roller is away from the fixing rod. After determining the fixing position, the fixing tape is wound around the outside of the drainage tube so that the fixing tape wraps multiple fixing rods. In the process of winding the fixing tape, excessive force should not be applied to avoid the fixing rod from pressing the drainage tube. After the fixing tape is wound around the outside of the drainage tube, the fixing rod can be initially fixed by viscosity, and then the fixing frame can be pulled to move. The movement of the fixing frame pulls the connecting rope to move, so that the connecting rope is tightened. The connecting rope can drive the roller to rotate to guide the movement of the connecting rope. After the connecting rope moves, the moving plate can be pulled to move. After the moving plate moves, it can drive the guide rod to move and limit the movement of the moving plate. After the moving plate moves, it can drive the two rollers to fit the fixing tapes on both sides of the fixing rod. The rollers can rotate with the movement of the moving plate. After the connecting rope is tightened, the rollers move to push the fixing tapes on both sides of the fixing rod to fit with both sides of the fixing rod, so that the contact area between the fixing tape and the fixing rod can be increased, and the fixing effect of the fixing rod can be improved, so as to avoid affecting the reliability of the drainage tube fixation. Through the fixing assembly, when fixing the drainage tube, several fixing rods can be reliably fixed by the fixing tape, and the fixing rod will not compress the drainage tube after being fixed, so as to avoid deformation of the drainage tube and discomfort to the patient, thereby improving practicality.

[0027] 2. When the connecting rope is pulled to move, the connecting rope drives the fixing ring to move, and the fixing ring fits with the fixing plate after moving. The fixing ring can contact with the positioning rod during the movement, and a notch is set on one side of the bottom end of the positioning rod, so that the movement of the fixing ring can push the positioning rod to move, and the reset spring can be stretched while the positioning rod moves. After the fixing ring fits with the fixing plate, the positioning rod is aligned with the positioning groove on the fixing ring, and then the reset spring can restore the deformation, so that the positioning rod is inserted into the positioning groove to position the fixing ring, so that the fixing ring can be positioned after the connecting rope is tightened. In the subsequent fixation process, the patient's position changes, and the skin has a certain elasticity, the connecting rope may become loose, and after the connecting rope becomes loose, the fixing ring will not move, so that the section from the fixing ring to the moving plate on the connecting rope will not become loose, thereby avoiding the resetting of the moving plate, avoiding the tape on both sides of the fixing rod from being lifted up due to the loosening of the connecting rope, and avoiding affecting the reliability of the drainage tube fixation;

[0028] 3. After the mounting ring is fixed, the handle can be pulled to drive the movable rod to slide on the positioning frame. The movement of the movable rod can stretch the telescopic spring, and the movable plate and the sponge pad can be lifted. Then, one end of the medical tape can be placed on the top of the fixed frame. Then, the handle is released, and the movable plate is reset under the action of the telescopic spring. The medical tape can be fixed by the engagement of the two sets of tooth plates, so that the tape is fixed to the bottom of the sponge pad, and the tape can be easily cut by a cutter, so that the adhesive surface of the tape is located below the fixed frame. After the mounting ring is fixed, the fixed frame can be pulled to tighten the connecting rope, and the fixed frame can be fixed by the tape under the sponge pad, so that the drainage tube can be fixed.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1-Figure 9 , the present invention provides a technical solution: a renal puncture fistula drainage device, comprising a drainage tube 1;

[0041] Also includes:

[0042] A fixing assembly 2 is arranged outside the drainage tube 1, and the fixing assembly 2 includes a mounting ring 201;

[0043] The mounting ring 201 is sleeved on the outside of the drainage tube 1, and a plurality of fixing rods 202 are fixedly mounted on the top of the mounting ring 201, and a fixing tape 203 is wound around the outside of the plurality of fixing rods 202, and a plurality of fixing plates 204 are fixedly mounted on the outside of the mounting ring 201, and guide rods 205 are symmetrically slidably connected to the upper inside of the fixing plates 204, and a movable plate 206 is fixedly mounted on one end of the two guide rods 205;

[0044] The mounting frame 207 is symmetrically mounted on the side of the movable plate 206 away from the fixed plate 204, a roller shaft 208 is rotatably connected between the two mounting frames 207, and the two roller shafts 208 are in contact with the fixing tape 203, and two groups of fixing frames 209 are symmetrically mounted on the top of the mounting ring 201 close to the fixed plate 204, and a roller 210 is rotatably connected between each group of two fixing frames 209, and a connecting rope 211 is symmetrically mounted on the bottom of the movable plate 206, and the connecting rope 211 is rotatably connected to the roller 210, and a through groove is symmetrically opened at the lower side of one side of the fixed plate 204, and the connecting rope 211 is adaptably connected to the through groove.

[0045] Embodiment 1: Figure 1-Figure 5As shown, a fixing component 2 is arranged on the outside of the drainage tube 1. When performing renal pelvic puncture, the end of the puncture device is connected to a display screen, and the tip is provided with an optical or electronic lens, so that the display screen can be observed for real-time puncture. After the puncture device punctures, the renal pelvis can be seen on the display screen. After puncture, the drainage tube 1 is inserted, and an optical fiber integrated body is used as a light-transmitting body to combine the image acquisition end and the puncture needle core. After integrating the puncture and endoscope functions, it is avoided to open an additional endoscope penetration port, and then the tissue image at the front end of the puncture needle core can be viewed in real time through the display screen, so that the vascular area can be avoided during puncture, and the probability of infection is reduced. When the drainage tube 1 is fixed, the mounting ring 201 is sleeved on the outside of the drainage tube 1. When the mounting ring 201 is fixed, the connecting rope 211 is in a relaxed state, and the roller 208 is away from the fixing rod 202. After the fixing position is determined, the fixing tape 203 is wound around the outside of the drainage tube 1 so that the fixing tape 203 wraps a plurality of fixing rods 202. In the process of winding the fixing tape 203, excessive force should not be applied to avoid causing the fixing rod 202 to press on the drainage tube 1. After the fixing tape 203 is wound around the outside of the drainage tube 1, the fixing rod 202 can be initially fixed by viscosity, and then the fixing frame 223 can be pulled. The fixed frame 223 moves and pulls the connecting rope 211 to move, so that the connecting rope 211 is tightened. The connecting rope 211 can drive the roller 210 to rotate to guide the movement of the connecting rope 211. After the connecting rope 211 moves, it can pull the moving plate 206 to move. After the moving plate 206 moves, it can drive the guide rod 205 to move to limit the movement of the moving plate 206. After the moving plate 206 moves, it can drive the two rollers 208 to fit the fixing tapes 203 on both sides of the fixed rod 202. The rollers 208 can rotate with the movement of the moving plate 206, and the connecting rope 211 is tightened. After tightening, the roller 208 moves to push the fixing tapes 203 on both sides of the fixing rod 202 to fit with the two sides of the fixing rod 202, so that the contact area between the fixing tapes 203 and the fixing rod 202 can be increased, and the fixing effect of the fixing rod 202 can be improved, avoiding affecting the reliability of the fixation of the drainage tube 1. Through the fixing component 2, when the drainage tube 1 is fixed, several fixing rods 202 can be reliably fixed by the fixing tapes 203, and the fixing rods 202 will not compress the drainage tube 1 after being fixed, which can avoid causing deformation of the drainage tube 1 and will not cause discomfort to the patient, thereby improving practicality.

[0046] A fixing ring 212 is fixedly installed on one side of the outer side of the two connecting ropes 211, and a fixing block 213 is fixedly installed on one side of the fixing plate 204 above the two fixing rings 212, and a positioning rod 214 is slidably connected inside the fixing block 213, and a positioning groove 215 is opened on the top of the fixing ring 212, and the positioning rod 214 is engaged with the positioning groove 215;

[0047] A return spring 216 is sleeved on one side of the outer portion of the positioning rod 214, and one end of the return spring 216 is fixedly connected to the fixing block 213, and a mounting block 217 is fixedly installed on the other end of the return spring 216, and the mounting block 217 is fixedly connected to the positioning rod 214;

[0048] A pull rope 218 is fixedly installed on the top of the two mounting blocks 217, and a through hole 219 is symmetrically penetrated on one side of the fixing plate 204 located above the two positioning rods 214, and both ends of the pull rope 218 pass through the through holes 219 and are fixedly connected to the two mounting blocks 217, and a support frame 220 is symmetrically installed on one side of the fixing plate 204 located below the two through holes 219, and a rotating wheel 221 is rotatably connected between the two support frames 220;

[0049] Limiting blocks 222 are fixedly installed on the other side of the two through holes 219 outside the pull rope 218 .

[0050] Embodiment 2: Figure 2-Figure 3 and Figure 6-Figure 8 As shown, during the movement of the connecting rope 211, the connecting rope 211 drives the fixing ring 212 to move, and the fixing ring 212 is fitted with the fixing plate 204 after moving. The fixing ring 212 can contact the positioning rod 214 during the movement. A notch is set on one side of the bottom end of the positioning rod 214, so that the movement of the fixing ring 212 can push the positioning rod 214 to move, and the positioning rod 214 can stretch the reset spring 216 while moving. After the fixing ring 212 is fitted with the fixing plate 204, the positioning rod 214 is aligned with the positioning groove 215 on the fixing ring 212, and then the reset spring 216 can restore the deformation, so that the fixing plate 204 is fixed. The positioning rod 214 is inserted into the positioning groove 215 to position the fixing ring 212, so that the fixing ring 212 can be positioned after the connecting rope 211 is tightened. Later, during the fixation process, the patient's position changes and the skin has a certain elasticity, and the connecting rope 211 may become loose. After the connecting rope 211 becomes loose, the fixing ring 212 will not move, so that the section from the fixing ring 212 to the movable plate 206 on the connecting rope 211 will not become loose, thereby preventing the movable plate 206 from being reset, and preventing the connecting rope 211 from loosening and causing the tapes on both sides of the fixing rod 202 to curl up, thereby preventing the reliability of the drainage tube 1 from being affected.

[0051] A fixed frame 223 is fixedly installed at one end of the two connecting ropes 211 away from the movable plate 206, and a movable plate 224 is arranged on the top of the fixed frame 223, and a sponge pad 225 is fixedly installed on the bottom of the movable plate 224. At the same time, toothed plates 226 are symmetrically installed on both sides of the top of the fixed frame 223 and both sides of the bottom of the movable plate 224, and the two sets of toothed plates 226 are engaged with each other.

[0052] The other two sides of the top of the fixed frame 223 are fixedly installed with positioning frames 227, and the inside of the positioning frames 227 is slidably connected with a movable rod 228, and the movable plate 224 is fixedly connected to the movable rod 228, and a telescopic spring 229 is sleeved on the upper part of the outer part of the movable rod 228, and one end of the telescopic spring 229 is fixedly connected to the positioning frame 227, and the other end of the telescopic spring 229 is fixedly installed with a handle 230, and the handle 230 is fixedly connected to the movable rod 228;

[0053] A cutter 231 is fixedly mounted on one side of the fixing frame 223 close to the connecting rope 211 .

[0054] Embodiment 3: Figure 2 and Fig. 9 As shown, after the mounting ring 201 is fixed, the handle 230 can be pulled to drive the movable rod 228 to slide on the positioning frame 227. The movement of the movable rod 228 can stretch the telescopic spring 229, so that the movable plate 224 and the sponge pad 225 can be lifted, and then one end of the medical tape can be placed on the top of the fixed frame 223, and then the handle 230 is released, and the movable plate 224 is reset under the action of the telescopic spring 229, and the medical tape can be fixed by the engagement of the two sets of tooth plates 226, so that the tape is fixed to the bottom of the sponge pad 225, and the cutter 231 is used to facilitate cutting of the tape, so that the adhesive surface of the tape is located below the fixed frame 223, and after the mounting ring 201 is fixed, the fixed frame 223 can be pulled to tighten the connecting rope 211, and the fixed frame 223 is fixed by the tape under the sponge pad 225, so that the drainage tube 1 can be fixed.

[0055] Working principle: When using the renal puncture fistula drainage device, first, according to Figure 1-Figure 9As shown, when the drainage tube 1 is fixed, the mounting ring 201 is sleeved on the outside of the drainage tube 1. When the mounting ring 201 is fixed, the connecting rope 211 is in a relaxed state, and the roller 208 is away from the fixing rod 202. After the fixing position is determined, the fixing tape 203 is wound around the outside of the drainage tube 1, so that the fixing tape 203 wraps a plurality of fixing rods 202. In the process of winding the fixing tape 203, excessive force should not be applied to avoid causing the fixing rods 202 to press on the drainage tube 1. After the fixing tape 203 is wound around the outside of the drainage tube 1, the fixing rods 202 can be initially fixed by viscosity, and then the fixing frame 223 can be pulled to move. The movement of the fixing frame 223 pulls the connecting rope 211 to move, so that the connecting rope 211 is tightened, and the connecting rope 211 can drive The roller 210 rotates to guide the movement of the connecting rope 211. After the connecting rope 211 moves, it can pull the movable plate 206 to move. After the movable plate 206 moves, it can drive the guide rod 205 to move and limit the movement of the movable plate 206. After the movable plate 206 moves, it can drive the two rollers 208 to fit the fixed tapes 203 on both sides of the fixed rod 202. The rollers 208 can rotate with the movement of the movable plate 206. After the connecting rope 211 is tightened, the rollers 208 move to push the fixed tapes 203 on both sides of the fixed rod 202 to fit the two sides of the fixed rod 202, so that the contact area between the fixed tapes 203 and the fixed rod 202 can be increased, and the fixing effect of the fixed rod 202 can be improved, so as to avoid affecting the reliability of the fixation of the drainage tube 1.

[0056] When the connecting rope 211 is pulled to move, the connecting rope 211 drives the fixing ring 212 to move. After the fixing ring 212 moves, it fits with the fixing plate 204. The fixing ring 212 can contact the positioning rod 214 during the movement. A notch is set on one side of the bottom end of the positioning rod 214, so that the movement of the fixing ring 212 can push the positioning rod 214 to move. While the positioning rod 214 moves, the return spring 216 can be stretched. After the fixing ring 212 fits with the fixing plate 204, the positioning rod 214 is aligned with the positioning groove 215 on the fixing ring 212. Then the return spring 216 can restore the deformation, so that the positioning rod 214 is inserted into the positioning groove 215 to position the fixing ring 212, so that the fixing ring 212 can be positioned after the connecting rope 211 is tightened. In the subsequent fixation process, the patient's position changes and the skin has a certain elasticity, the connecting rope 211 may be loose, and the fixing ring 212 will not move after the connecting rope 211 is loosened, so that the fixing ring 212 on the connecting rope 211 is The movable plate 206 will not be loosened, thereby preventing the movable plate 206 from resetting and preventing the connection rope 211 from loosening and causing the tapes on both sides of the fixed rod 202 to tilt. After the mounting ring 201 is fixed, the handle 230 can be pulled to drive the movable rod 228 to slide on the positioning frame 227. The movement of the movable rod 228 can stretch the telescopic spring 229, so that the movable plate 224 and the sponge pad 225 can be lifted. Then, one end of the medical tape can be placed on the top of the fixed frame 223, and then the handle 230 can be released. Under the action of the telescopic spring 229, the movable plate 224 is reset, and the medical tape can be fixed by the engagement of the two sets of tooth plates 226, so that the tape is fixed to the bottom of the sponge pad 225, and the cutter 231 is used to cut the tape so that the adhesive surface of the tape is located below the fixed frame 223. After fixation, the mounting ring 201 can pull the fixed frame 223 to tighten the connecting rope 211, and fix the fixed frame 223 by the tape under the sponge pad 225, so that the drainage tube 1 can be fixed.
