Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a nephrostomy sealing tube. Background Art
[0002] Urinary stones are common diseases in urology in my country, and they account for the largest number of inpatients in urology. The most common treatments for urinary stones include extracorporeal shock wave lithotripsy (ESWL), ureteroscopic lithotomy (URL), retrograde intrarenal surgery (RIRS), and percutaneous nephrostolithotomy (PCNL). PCNL was first successfully used to treat kidney stones in 1976. Due to its advantages of less damage to tissues and organs, high stone clearance rate, and rapid postoperative recovery of patients, as well as the further application of endoscopic equipment in urology and the update of technology, PCNL has greatly improved the success rate of stone removal, reduced complications and recurrence rates. Therefore, PCNL has gradually replaced open surgery and become the preferred method for treating kidney stones, especially large or complex kidney stones.
[0003] There are currently two trends in the development of PCNL. One is microtubulation, where the puncture channel becomes thinner to reduce damage to the patient's body; the other is tubeless, which means selectively not placing a nephrostomy tube or even a ureteral stent in the patient.
[0004] In microtubular treatment, drainage is required, so the part of the nephrostomy tube outside the body is longer and needs to be connected to a drainage bag, which makes the patient inconvenient to move, poor comfort, and inconvenient postoperative care. As for tubeless treatment, although it is less traumatic than open surgery, it still has the risk of serious complications such as severe bleeding, residual stones, septic shock, etc., and if there are still residual stones after surgery, a second puncture is required when a second-stage PCNL treatment is required, which increases the patient's pain.

[0015] Compared with the prior art, the utility model has achieved the following technical effects:
[0016] The utility model provides a nephrostomy closure tube, which combines the effects of the existing PCNL micro-tubing and tubeless by closing the outer end of the drainage main tube with a closing plug. When the situation permits, the drainage bag can be disconnected, so that the patient's comfort is significantly improved. The length of the drainage main tube extending out of the body can be shortened according to actual needs, and the end is directly fixed on the patient's skin, which is convenient for postoperative care. When the patient's condition requires drainage, the closing plug can be opened, and the drainage bag can be connected to promote kidney drainage. At this time, the end drainage port of the drainage main tube and multiple side drainage ports can all support Drainage, timely and sufficient drainage can reduce the occurrence of infection, accelerate wound healing, reduce the formation of urinary cysts, and reduce the risk of postoperative infection; and when a second-stage PCNL is required, re-puncture can be avoided, so that residual stones can be removed more conveniently, reducing patient pain and achieving a rapid recovery effect; and the use of an injection tube in conjunction with the concave shelf groove set on the drainage main tube can minimize the outer diameter of the tube compared to the traditional inner and outer outer tube structure, and it does not protrude from the outer wall of the drainage main tube, which is convenient for catheterization operation; and it does not affect the truncation operation of the drainage main tube at one end outside the patient's body.
[0017] Furthermore, the injection tube is composed of two parts, an integrated tube section and a branch tube section. The integrated tube section is integrated with the drainage main tube so that the catheterization operation is not affected and the relative positions of the integrated tube section, the water bag and the drainage main tube are firmly fixed. The branch tube section is equipped with a concave resting groove so that it is not affected by the truncation operation of the outer end of the drainage main tube and is convenient for the catheterization operation of this section.
[0018] Furthermore, the flat-end design makes the end of the drainage main pipe more regular and in closer contact with the internal tissue of the kidney, reducing blind spots in drainage. During the drainage process, the accumulated fluid and pus in the kidney can enter the drainage channel more smoothly through the end drainage port; avoiding the end of the drainage main pipe from being embedded in the tissue can reduce damage to the kidney tissue, which helps to reduce the probability of complications such as bleeding and inflammation, protect kidney function, and promote patient recovery.
[0019] Furthermore, when placing a closed tube during a nephrostomy operation, the doctor can use the scale lines to accurately determine the depth to which the main drainage tube is inserted into the kidney, which helps ensure that the end drainage port and the drainage ports on each side of the main drainage tube are in appropriate positions, and can effectively drain the accumulated fluid and pus in the kidney, thereby improving the success rate of the operation and the therapeutic effect; the scale lines and scale values can be used as part of the nursing records, making it convenient for medical staff to record information such as the insertion depth and position changes of the main drainage tube. These data are of great significance for evaluating the patient's disease progression and treatment effect, and help improve the quality of nursing and the accuracy of medical decisions.
[0020] Furthermore, the elastic sealing plug can tightly seal the injection hole to prevent the liquid in the water bag from leaking, which ensures that the water bag can maintain a stable pressure after expansion, effectively prevents it from shifting or falling out, and can play a role in compression and hemostasis.
[0021] Furthermore, the fixing piece can firmly fix the end of the drainage main tube on the patient's skin to prevent the drainage main tube from shifting during the patient's activities or daily care. The stable drainage main tube can reduce stimulation to the kidneys and surrounding tissues and improve the patient's comfort.
[0022] Furthermore, the adhesive patch is very convenient to use, and medical staff can quickly fix the drainage tube on the patient's skin.
[0023] Furthermore, the closing plug is composed of a sealing head and a limiting head, and the shape of the sealing head corresponds to the internal shape of the end opening of the drainage main pipe. After the end of the drainage main pipe is cut off as needed, the closing plug can still achieve the adaptation of the sealing head to the shape of the position to be blocked, thereby facilitating the sealing function of the opening after cutting off; the limiting head can ensure the blocking position of the sealing head and ensure that the blocking is in place.

[0036] By sealing the outer end of the drainage main pipe 10 with a closure plug 20, the effects of the existing PCNL micro-tubing and tubeless are combined. When conditions permit, the drainage bag may not be connected, which significantly improves the patient's comfort. The length of the drainage main pipe 10 extending out of the body can be shortened according to actual needs, and the end is directly fixed on the patient's skin, which is convenient for postoperative care. When the patient's condition requires drainage, the closure plug 20 can be opened, and the drainage bag can be connected to promote kidney drainage. At this time, the end drainage port 11 and multiple side drainage ports 12 of the drainage main pipe 10 can support drainage, so that timely , sufficient drainage can reduce the occurrence of infection, accelerate wound healing, reduce the formation of urinary cysts, and reduce the risk of postoperative infection; and when a second-stage PCNL is required, re-puncture can be avoided, so that residual stones can be removed more conveniently, reducing the patient's pain and achieving a rapid recovery effect; and the use of an injection tube in conjunction with the concave shelf groove 13 set on the drainage main tube 10 can minimize the outer diameter of the tube compared to the structure of a traditional inner and outer outer tube, and does not protrude from the outer wall of the drainage main tube 10, which facilitates the catheterization operation; and does not affect the truncation operation of the drainage main tube 10 at one end outside the patient's body.
[0037] In order to achieve better catheter placement and truncation of the length of the drainage main tube 10 outside the patient's body, the following settings may also be made:
[0038] In the optional scheme of this embodiment, it is more preferred that Figure 1 As shown, the injection tube includes an integrated tube section and a branch tube section 31; the integrated tube section is integrated with the drainage main pipe 10, and one end of the integrated tube section is connected and communicated with the water bag 30, and the other end of the integrated tube section is connected and communicated with one end of the branch tube section 31; an injection joint 32 is provided at one end of the branch tube section 31 away from the integrated tube section, and the concave shelf 13 corresponds to the branch tube section 31.

The integrated tube section is designed to be integrated with the drainage main pipe 10, so that the catheterization operation is not affected, and the relative position of the integrated tube section and the water bag 30 and the drainage main pipe 10 is fixed firmly; and the branch tube section 31 cooperates with the concave shelf 13, so that it is not affected by the truncation operation of the outer end of the drainage main pipe 10, and it is also convenient for the catheterization operation of this section.
[0039] In the optional scheme of this embodiment, it is more preferred that Figure 1As shown, the closing plug 20 includes a plugging head 21 and a limiting head 22, and the plugging head 21 is fixedly connected to the limiting head 22; the plugging head 21 corresponds to the internal shape of the end opening of the drainage main pipe 10; the side of the limiting head 22 close to the plugging head 21 is used to abut against the end of the drainage main pipe 10. The closing plug 20 is composed of the plugging head 21 and the limiting head 22, and the shape of the plugging head 21 corresponds to the internal shape of the end opening of the drainage main pipe 10. After the end of the drainage main pipe 10 is cut off as needed, the closing plug 20 can still achieve the shape of the plugging head 21 and the position to be blocked, so as to facilitate the opening blocking function after cutting off; the limiting head 22 can ensure the blocking position of the plugging head 21 and ensure the blocking is in place.
[0040] The structure of one end of the drainage main pipe 10 located in the patient's body is described as follows:
[0041] In the optional scheme of this embodiment, it is more preferred that Figure 1 As shown, the drainage main pipe 10 has a flat end with an end drainage port 11. The flat design makes the end of the drainage main pipe 10 more regular, and the contact with the internal tissue of the kidney is closer, reducing the drainage dead angle. During the drainage process, the effusion and pus in the kidney can enter the drainage channel more smoothly through the end drainage port 11; avoiding the end of the drainage main pipe 10 from being embedded in the tissue can reduce the damage to the kidney tissue, which helps to reduce the probability of complications such as bleeding and inflammation, protect kidney function, and promote the recovery of patients.
[0042] Among them, in order to facilitate the controllability and visualization of the insertion length, it can also be set as follows:
[0043] In the optional scheme of this embodiment, it is more preferred that Figure 1 As shown, the outer wall of the drainage main tube 10 is provided with scale lines 14 and corresponding scale values 15. When placing a closed tube during nephrostomy surgery, the doctor can accurately judge the depth of the drainage main tube 10 inserted into the kidney through the scale lines 14, which helps to ensure that the end drainage port 11 and the drainage ports 12 on each side of the drainage main tube 10 are in a suitable position, and can effectively drain the effusion and pus in the kidney, thereby improving the success rate of the operation and the treatment effect; the scale lines 14 and the scale values 15 can be used as part of the nursing record, which is convenient for medical staff to record the insertion depth and position changes of the drainage main tube 10 and other information. These data are of great significance for evaluating the patient's disease progression and treatment effect, and help to improve the quality of nursing and the accuracy of medical decision-making.
[0044] Among them, the means for realizing the sealing function in the injection connector 32 are:
[0045] In the optional scheme of this embodiment, it is more preferred that Figure 1As shown, the injection connector 32 has an injection hole, and the injection hole is blocked by an elastic sealing plug 33. The elastic sealing plug 33 can tightly block the injection hole to prevent leakage of the liquid in the water bag 30. This ensures that the water bag 30 can maintain a stable pressure after expansion, effectively prevents it from shifting or falling out, and can play a role in compression and hemostasis.
[0046] Specifically, in addition to the above-mentioned elastic sealing plug 33, other existing structural arrangements that can achieve the same function can also be used.
[0047] The fixing of the ends of the drainage main tube 10 and the injection tube outside the patient's body is as follows:
[0048] In the optional scheme of this embodiment, preferably, a fixing piece is provided at one end of the drainage main pipe 10 close to the closure plug 20, and the fixing piece is used to be fixed on the patient's skin. The fixing piece can firmly fix the end of the drainage main pipe 10 on the patient's skin to prevent the drainage main pipe 10 from shifting during the patient's activities or daily care. The stable drainage main pipe 10 can reduce the stimulation to the kidney and surrounding tissues and improve the patient's comfort.
[0049] In the optional scheme of this embodiment, it is more preferred that the fixing member is an adhesive patch or a suture needle and thread. The adhesive patch is very convenient to use, and the medical staff can quickly fix the drainage main tube 10 on the patient's skin; the suture needle and thread can fix the drainage main tube 10 on the patient's skin very firmly, and it is not easy to loosen or fall off.
[0050] Specifically, the fixing form of the end of the injection tube outside the patient's body may be the same as the fixing form of the drainage main tube 10 or other existing fixing forms.
[0051] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
