Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1 to 4, the kidney temperature control bag according to the embodiment of the present invention includes a bag body 1, a closing member 2, and a temperature control member. The bag body 1 is provided with an accommodating cavity, and the shape of the bag body 1 is matched with that of the kidney. The bag body 1 is provided with a first opening 101 for putting the kidney into the accommodating chamber and a second opening 102 for extending the renal pedicle 8 of the kidney in the accommodating chamber. The closing member 2 is used for closing the first opening 101, and the closing member 2 is provided on the bag body 1. The temperature control piece is arranged on the bag body 1 and is provided with a temperature control channel 3 for enabling temperature control liquid to flow. Or a temperature control channel 3 for flowing temperature control liquid is defined between the temperature control piece and the bag body 1.

According to the utility model discloses supply kidney accuse temperature bag, through the shape phase-match that sets up the bag body 1 and supply the kidney, promptly supply the kidney to put into the holding chamber by first opening 101 and close first opening 101 back through closing member 2, bag body 1 and the shape phase-match that supplies the kidney. Therefore, the occupied space of the bag body 1 when the bag body is placed in a patient body is reduced to the maximum extent, and when the kidney supply moves to a proper position in the body, the bag body 1 is not contacted with other parts in the patient body or even extruded, so that the risk of kidney supply transplantation is reduced. Moreover, through the shape phase-match that sets up bag body 1 and supply the kidney, supply the kidney to put into the holding chamber by first opening 101 and close first opening 101 through closure member 2 after, supply the outer surface of kidney and the interior wall surface of holding chamber to laminate each other basically, and then supply the outer surface of kidney to be closer to the temperature-controlled channel 3 of establishing on bag body 1. Therefore, the efficiency of heat exchange between the temperature control liquid in the temperature control channel 3 and the outer surface of the kidney is higher, and the temperature control piece can better complete the adjustment of the temperature of the kidney to keep the kidney in a proper temperature range, thereby further reducing the risk of kidney transplantation.

As used herein, the terms "inner", "outer", "upper", "lower", "anterior", and "posterior" shall be given their commonly understood anatomical interpretation. By "posterior side" is meant the back of the patient, e.g., the back of the kidney. Similarly, "anterior" refers to the front of the patient, e.g., the front of the kidney. Thus, "rear" refers to the opposite direction of "front". The "inner edge" is the side of the kidney where the hilum and the pedicle 8 are located, or the side that is concave. The "outer edge" is the side of the kidney facing opposite the "inner edge", or convex.

For easy understanding, arrow a in fig. 1 indicates the inside and outside direction of the kidney temperature control bag, arrow B in fig. 1 indicates the up-down direction of the kidney temperature control bag, arrow C in fig. 3 indicates the front-back direction of the kidney temperature control bag, and arrow D in fig. 1 indicates the left-right direction of the kidney temperature control bag. In addition, in the robotic kidney transplant, the angle of view of the robotic operator is passed by the patient's head and directed downward toward the abdominal cavity, and therefore, the up-down direction at this angle of view is exactly opposite to the actual up-down direction of the donor kidney. Furthermore, the orientation of the second opening 102 of the kidney temperature control bag is different according to the position of the kidney implanted in the abdominal cavity. When it is desired to implant a donor kidney into the right side of the abdominal cavity to anastomose the donor kidney to the right iliac vessels of the patient, the second opening 102 is positioned to the right of the first opening 101 from the perspective of the robotic operator, as shown in fig. 1. If it is desired to implant a donor kidney into the left side of the abdominal cavity to anastomose the donor kidney to the patient's left iliac vessels, the second opening 102 is located to the left of the first opening 101 from the perspective of the robotic operator, as shown in fig. 4.

It should be noted that the kidney temperature control bag according to the embodiment of the present invention can be applied to not only the robot kidney transplantation operation but also the open operation.

As shown in fig. 1-3, the kidney temperature control bag can comprise a bag body 1, a closing member 2, a temperature control member, a lock catch 4, a circulating pump, a cold liquid tank, a warm liquid tank and a traction belt 6.

Wherein the bag body 1 comprises a front side part 103 and a back side part 104 which are connected, the outer edge of the front side part 103 and the outer edge of the back side part 104 are both convex shapes which are matched with the outer edge of the kidney, and the shape of each of the inner edge of the front side part 103 and the inner edge of the back side part 104 is matched with the shape of the inner edge of the kidney. A portion of the inner edge of the front side portion 103 is recessed toward the outer edge of the front side portion 103 relative to the remainder of the inner edge of the front side portion 103, and a portion of the inner edge of the back side portion 104 is recessed toward the outer edge of the back side portion 104 relative to the remainder of the inner edge of the back side portion 104. At least a portion of the outer edge of the anterior portion 103 and at least a portion of the outer edge of the posterior portion 104 encircle a first opening 101, and a portion of the inner edge of the anterior portion 103 and a portion of the inner edge of the posterior portion 104 encircle a second opening 102 corresponding to the hilum of the kidney.

Therefore, the size of the second opening 102 is substantially the size of the hilum of the kidney, thereby avoiding the other tissues of the kidney except the renal pedicle 8 from being exposed from the second opening 102, and further ensuring the temperature control effect of the temperature control liquid on the tissues of the kidney except the renal pedicle 8. Moreover, by providing the inner edges of the front side portion 103 and the back side portion 104 as concave shapes matching the inner edge of the kidney, more tissue from the renal pedicle 8 can be exposed through the second opening 102 to reduce the interference of the bag 1 with the operation (e.g., interference with the suturing of the arteriovenous in the renal pedicle 8). In addition, the first opening 101 is arranged to correspond to the outer edge of the kidney and opposite to the second opening 102, so that the kidney can move relative to the inner and outer directions of the bag body 1 to be placed in the accommodating cavity, and the kidney pedicle 8 of the kidney can extend out of the accommodating cavity from the second opening 102 more conveniently and safely.

Specifically, a portion of the inner edge of the front side portion 103 is located at the middle of the inner edge of the front side portion 103, and a portion of the inner edge of the rear side portion 104 is located at the middle of the inner edge of the rear side portion 104. That is, the second opening 102 is located at the middle of the inner side of the pouch body 1 in the up-down direction of the pouch body 1 to correspond to the hilum located at the middle of the inner edge of the kidney.

In some embodiments, a cut-out 1031 is provided on the front side portion 103, the cut-out 1031 extends to the edge of the second opening 102 along the inner and outer directions of the front side portion 103, and the temperature control channel 3 is distributed in a serpentine shape on the rear side portion 104 and the area of the front side portion 103 except for the cut-out 1031.

Thus, after the kidney transplantation operation is completed, the cut-out 1031 may be cut out from the second opening 102 along the inside-outside direction of the pouch body 1 to form an opening capable of detaching the pouch body 1 from the kidney. The size of this opening includes the size of second opening 102, and then need not cut overlength and form this opening big enough, and the length of cutting 1031 can be littleer, and then makes front portion 103 have more regions and let temperature control channel 3 distribute to accomplish the regulation to the surface temperature who supplies the kidney more evenly, effectively avoid supplying that the surface temperature of kidney is inhomogeneous. Moreover, through setting up cutting area 1031, avoid cutting out temperature control channel 3 at the maloperation when cutting out bag body 1, avoid the temperature control liquid to get into the patient in vivo and cause the emergence of unfavorable condition such as infection.

Specifically, as shown in fig. 1 and 2, a trimming area 1031 is located at a substantially middle position of the front side portion 103 in the up-down direction, the trimming area 1031 dividing other areas of the front side portion 103 into an upper area and a lower area. The temperature control channel 3 enters the lower area from the upper part of the lower area close to the outer side position and is laid on the lower area from top to bottom, then is laid on the rear side part 104 from bottom to top, then is laid on the upper area from top to bottom and finally extends out of the upper area from the lower part of the upper area close to the outer side position.

It should be noted that the bag body 1 is preferably made of a soft material, so as to facilitate the close adhesion of the bag body 1 to the kidney, and also facilitate the cutting of the bag body 1.

In some embodiments, the front side 103 and the rear side 104 each comprise a thermally insulating layer and a thermally conductive layer, the thermally insulating layer being arranged on a side of the thermally conductive layer facing away from the receiving cavity, the temperature controlled channel 3 being located between the thermally insulating layer and the thermally conductive layer. From this, the heat insulating layer effectively avoids the heat in the abdominal cavity to cause the influence to accuse temperature bag, and the heat-conducting layer also makes accuse temperature 3 and supplies the heat exchange efficiency between the kidney surface higher. Moreover, through setting up temperature-controlled channel 3 between heat-conducting layer and insulating layer, further separate heat-conducting channel and confession kidney, pollute the confession kidney that is located the holding intracavity when avoiding heat-conducting channel to damage.

Optionally, the temperature-controlled channel 3 is a hose, which is arranged between the heat-insulating layer and the heat-conducting layer. Therefore, the kidney temperature control bag is simple and convenient to manufacture.

In particular, the hose may be secured to at least one of the thermally and thermally insulating layers by means of adhesive.

Alternatively, the gap between the heat insulating layer and the heat conducting layer can be sewn by fine threads or bonded by glue to form a channel which is communicated with each other and forms the temperature control channel 3.

In some embodiments, at least one of the front side 103 and the back side 104 is provided with a temperature sensor 5 for detecting the surface temperature of the donor kidney. The temperature of the temperature control liquid can be adjusted in real time according to the temperature detected by the temperature sensor 5, so as to ensure that the kidney supply is continuously kept in a proper temperature range.

In particular, the temperature sensor 5 may be provided between the thermally insulating layer and the thermally conductive layer. Or the temperature sensor 5 is arranged on one side of the heat conduction layer, which is far away from the heat insulation layer.

In some embodiments, the closure member 2 includes a drawstring 2a, a portion of the front side portion 103 adjacent to the outer edge thereof is provided with a first plurality of perforations, a portion of the back side portion 104 adjacent to the outer edge thereof is provided with a second plurality of perforations, and the drawstring 2a is threaded through the first plurality of perforations and the second plurality of perforations. Thus, by pulling the tether 2a, the rear edge of the front portion 103 and the rear edge of the rear portion 104 can be brought close to each other and attached to each other, thereby closing the first opening 101.

Specifically, the binding rope 2a alternately penetrates through the first penetrating seam and the second penetrating seam from top to bottom, and the pulling end of the binding rope 2a finally extends out of the uppermost first penetrating seam or the uppermost second penetrating seam. The closing of the first opening 101 is achieved by pulling the drawstring 2a upward.

Alternatively, the closing element 2 can also be a zip fastener, also enabling the effect of closing the first opening 101. Alternatively, the closure member 2 may also be in the form of a snap-fit strap, such as a strap having an end that is received in a snap fit, which also serves to close the first opening 101.

In some embodiments, the kidney temperature control bag further comprises a latch 4, and the second opening 102 has first and second ends opposite in the extending direction inside the front side 103. The catch 4 is connected to a portion of the front side 103 adjacent to its inner edge and a portion of the back side 104 adjacent to its inner edge, the catch 4 being located between the first and second ends in the direction of extension of the inner edge of the front side 103. Therefore, after the renal pedicle 8 at the renal hilum extends out of the accommodating cavity from the second opening 102, the lock catch 4 enables a part of the inner edge of the front side part 103 and a part of the inner edge of the rear side part 104 to be close to and attached to each other, so that the size of the second opening 102 is reduced, further more tissues of the kidney are prevented from being exposed outside, and the temperature control effect of the kidney supply temperature control bag on the kidney supply is effectively guaranteed.

According to the position of the renal pedicle 8 for the kidney, if the renal pedicle 8 is very close to the upper pole, the latch 4 close to the upper pole is opened, and the latch 4 close to the lower pole is closed. If the renal pedicle 8 is more close to the lower pole, the latch 4 close to the lower pole is opened and the latch 4 close to the upper pole is closed. Whereby the reduction control of the size of the second opening 102 is more flexible.

In some embodiments, the kidney temperature control bag further comprises a circulation pump, a three-way valve, and a cold liquid tank and a warm liquid tank for storing the temperature control liquid. The circulation pump has an inlet and an outlet. The three-way valve is provided with a first inlet, a second inlet and an outlet, and the outlet of the three-way valve is communicated with the inlet of the circulating pump.
