Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a kidney bag specially used in kidney transplantation surgery. Background Art

[0002] Kidney transplantation is the most effective measure to save the lives of patients with chronic renal failure and the best alternative treatment for patients with end-stage renal disease. Kidney transplantation, commonly known as kidney replacement, is to transplant an allogeneic kidney in the patient's iliac fossa, anastomose the renal blood vessels with the recipient blood vessels, and directly implant the ureter in the bladder. During the vascular anastomosis process, in order to ensure the recovery of the function of the transplanted kidney after surgery, reduce the delayed function of the transplanted kidney and the incidence of postoperative transplanted kidney dysfunction, and ensure the long-term survival of the transplanted kidney, the cryopreservation of the donor kidney is crucial. The current technology is to place the donor kidney in a kidney bag containing crushed ice, cut a small hole at the bottom of the bag, and lead out the kidney blood vessels for anastomosis, but the existing technology design is too simple, and there are certain defects in the low-temperature protection of the donor kidney. The crushed ice is easy to melt and cannot be maintained at a low temperature (and ice water is easy to leak directly from the bag), which directly affects the effect of the operation. For this reason, the utility model proposes a kidney bag dedicated to kidney transplant surgery. Utility Model Content

[0003] The embodiment of the present application provides a kidney bag specially used for kidney transplantation surgery, which can maintain the donor kidney in a continuous low-temperature state and facilitate the operator's operation, thereby effectively reducing donor kidney damage.

[0004] In view of this, the present application provides a kidney bag dedicated to kidney transplant surgery, comprising: a sterile kidney bag and a sterile sealed ice bag for being placed in the sterile kidney bag;

[0005] The top opening of the sterile kidney bag is provided with a binding structure;

[0006] The bottom of the sterile kidney bag is provided with an easy-tear opening for pulling out the renal artery and vein during surgery;

[0007] Both the front and back sides of the sterile kidney bag are provided with easy-tear lines connected to the easy-tear opening.

[0008] Optionally, the constriction structure includes a constriction channel arranged on the top of the sterile kidney bag and a constriction rope passing through the constriction channel;

[0009] Rope outlets are formed at both ends of the tie-opening channel;

[0010] The two ends of the cinch rope extend to the outside of the cinch passage through the corresponding rope outlets respectively.

[0011] Optionally, the bottom of the sterile sealed ice bag is recessed inwards.

[0012] Optionally, a temperature detection device is provided on the outer surface of the sterile kidney bag.

[0013] Optionally, the temperature detection device is a temperature sticker.

[0014] Optionally, the tearable opening is located at the center of the bottom of the sterile kidney bag.

[0015] It can be seen from the above technical scheme that the embodiments of the present application have the following advantages: the kidney bag specially used for kidney transplant surgery includes a sterile kidney bag and a sterile sealed ice bag for being placed in the sterile kidney bag. The double-bag design is convenient for timely replacement, thereby facilitating the maintenance of a continuous low temperature state of the donor kidney. At the same time, an easy-tear opening is provided at the bottom of the sterile kidney bag for pulling out the donor kidney artery and vein for vascular anastomosis during surgery. Easy-tear lines connected to the easy-tear opening are provided on both sides of the sterile kidney bag, so that after the artery and vein are connected to the human body (i.e., the vascular anastomosis is completed), the sterile kidney bag can be torn open through the easy-tear line to remove the donor kidney, thereby reducing damage to the donor kidney.

[0023] This application provides an embodiment of a kidney bag for kidney transplant surgery. Figure 1 and Figure 2 .

[0024] The kidney bag specially used for kidney transplantation surgery in this embodiment includes: a sterile kidney bag 1 and a sterile sealed ice bag 2 for being placed in the sterile kidney bag 1, a binding structure 11 is provided at the top opening of the sterile kidney bag 1, and an easy-tear opening 12 is provided at the bottom of the sterile kidney bag 1 for pulling out the artery and vein of the donor kidney 4 during surgery, and easy-tear lines 13 connected to the easy-tear opening 12 are provided on both the front and back sides of the sterile kidney bag 1.

[0025] It should be noted that: the kidney bag specially used for kidney transplantation surgery includes a sterile kidney bag 1 and a sterile sealed ice bag 2 for being placed in the sterile kidney bag 1. The double-bag design is convenient for timely replacement, thereby facilitating the maintenance of a continuous low temperature state of the donor kidney 4. At the same time, a tear-off opening 12 for pulling out the artery and vein of the donor kidney 4 for vascular anastomosis during surgery is provided at the bottom of the sterile kidney bag 1. Tear-off lines 13 connected to the tear-off opening 12 are provided on both sides of the sterile kidney bag 1, so that after the artery and vein are connected to the human body (i.e., the vascular anastomosis is completed), the sterile kidney bag 1 can be torn open through the tear-off line 13 to remove the donor kidney 4, thereby reducing damage to the donor kidney 4.

[0026] The above is the first embodiment of a kidney bag for kidney transplantation provided by the present application. The following is the second embodiment of a kidney bag for kidney transplantation provided by the present application. For details, please refer to Figure 1 and Figure 2 .

[0027] The kidney bag for kidney transplantation surgery in this embodiment includes: a sterile kidney bag 1 and a sterile sealed ice bag 2 for being placed in the sterile kidney bag 1, a binding structure 11 is provided at the top opening of the sterile kidney bag 1, and an easy-tear opening 12 is provided at the bottom of the sterile kidney bag 1 for pulling out the artery and vein of the donor kidney 4 during surgery, and easy-tear lines 13 connected to the easy-tear opening 12 are provided on both the front and back sides of the sterile kidney bag 1, so as to facilitate tearing and use during kidney transplantation surgery.

[0028] The drawstring structure 11 includes a drawstring channel arranged on the top of the sterile kidney bag 1 and a drawstring rope 111 passing through the drawstring channel. Rope outlets are formed at both ends of the drawstring channel, and both ends of the drawstring rope 111 extend out of the drawstring channel through corresponding rope outlets.

[0029] It should be noted that the top opening of the sterile kidney bag 1 can be tightened by the drawstring 111, and the kidney bag can be directly hung and fixed on the renal transplant surgery expander by using the drawstring 111, avoiding the current situation of manual fixation, which not only reduces the workload of the surgeon, but also is more conducive to expanding the surgical field of view and facilitating the surgeon's operation.

[0030] The bottom of the sterile sealed ice pack 2 is concave inwardly, and is used to wrap the donor kidney 4 to make it fit better.

[0031] The outer surface of the sterile kidney bag 1 is provided with a temperature detection device. Specifically, the temperature detection device can be a temperature sticker 3, which can directly reflect the temperature of the sterile sealed ice pack 2. When the temperature exceeds 4°C, the temperature sticker 3 changes color, which is more intuitive and helps to remind medical staff to replace the sterile sealed ice pack 2 in time when the required temperature is exceeded.

[0032] Specifically, the easy-tear opening 12 is located at the center of the bottom of the sterile kidney bag 1 .

[0033] During the specific implementation, first prepare a sterile sealed ice pack 2 (filled with ice and sealed to prevent the liquid from melting the ice from flowing out). Before anastomosing the blood vessels of the donor kidney 4 with the iliac blood vessels, identify the artery and vein of the donor kidney 4 and the upper and lower poles of the donor kidney 4, then place the donor kidney 4 in the sterile kidney bag 1, and then place the sterile sealed ice pack 2 around the donor kidney 4. After exhausting the gas, tighten the drawstring 111 to seal the sterile kidney bag 1, and tie the drawstring 111 to the retractor used for kidney transplantation surgery; then manually tear open the easy-tear opening 12 at the bottom of the sterile kidney bag 1, pull out the artery and vein of the donor kidney 4 for vascular anastomosis, observe the color change of the temperature sticker 3 on the sterile kidney bag 1 during the anastomosis process, and then replace the sterile sealed ice pack 2 in time to keep the donor kidney 4 in a continuous low temperature state. After the vascular anastomosis is completed, the donor kidney 4 can be taken out by tearing open the easy-tear line 13 in the middle of the sterile kidney bag 1.

[0034] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
