Description

Technical Field

[0001] The invention belongs to the technical field of special environment creation, and in particular relates to a method for creating a local low-temperature kidney environment for laparoscopic surgery. Background Art

[0002] With the continuous development of laparoscopic technology, its application in surgical operations is becoming more and more extensive. In addition, the development of new image sensors and digital image processing technology has promoted the emergence of new laparoscopes, such as stereoscopic laparoscope (3D) technology, which makes intraoperative positioning more accurate.

[0003] Therefore, laparoscopic technology can be applied in surgical operations to obtain a clear surgical field of view. For example, in kidney surgery, medical staff can open a 12mm TROCAR hole on the patient's skin surface and insert a laparoscope through the hole to observe the patient's perirenal tissue. Because the kidney is one of the largest filtering organs in the human body and has a very rich blood supply, blood flow needs to be blocked for a period of time during surgery. However, the blood flow blocking time should not exceed 30 minutes, otherwise the kidney will be necrotic due to long-term ischemia. However, the blood flow blocking time is short and cannot meet the time requirements of surgical operations.

[0004] A new technology needs to be designed to extend the time that the kidneys can withstand blood flow blockage, reduce the kidney's metabolic rate while maintaining cell vitality, and thereby obtain a longer surgical operation time. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a method for creating a local low-temperature environment of the kidney for laparoscopic surgery, so as to solve the problem that under normal circumstances, the blood flow blockage time that the organ can withstand is short and cannot meet the surgical needs of the operator.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A method for creating a local low-temperature environment of the kidney for laparoscopic surgery, comprising:

[0008] Pre-place 500-1000 ml of ice mud into the patient's body cavity and around the kidney through the 12 mm TROCAR hole;

[0013] The ice slurry conveying part is used to convey the ice slurry inside the heat preservation pot to the outside, and comprises an output pump connected to the box cover and an output pipe fixedly installed at the output end of the output pump, the upper end of the output pipe penetrates and extends to the top of the box cover, a guide pipe is sleeved on the output pipe, and a fixing assembly for fixing the guide pipe is provided;

[0014] The temperature monitoring part is used to monitor the tissue temperature of the part where the ice mud is preset in the patient's body cavity, including a wire plugged into the box cover and a temperature probe connected to the end of the wire;

[0015] The control unit is used to receive the tissue temperature information of the preset ice mud position in the patient's body cavity collected by the temperature monitoring unit, and control the amount of ice mud output by the ice mud conveying unit according to the change of tissue temperature, including a controller fixedly installed on the box cover, and the controller is connected to the output pump and the wire.

[0016] Preferably, the insulation box is provided with heat exchange tubes surrounding the insulation pot.

[0017] Preferably, the fixing assembly comprises a clip fixedly mounted on the output pipe, the clip is arranged obliquely, and an abutment cylinder which can be slidably abutted against the clip is threadedly connected to the output pipe.

[0020] Preferably, an electric valve for blocking the conduit is arranged inside the control handle, and the start and stop of the electric valve are consistent with the output pump and are controlled by the switch.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] According to the method of the present invention, during the operation, 500 ml of ice mud is pre-placed into the perirenal area of ​​the patient's body cavity through the 12 mm TROCAR hole. The ice mud is small-particle ice. The ice mud can absorb the heat of the perirenal tissue, reduce the temperature of the perirenal tissue, and maintain a low-temperature environment of the perirenal tissue for a certain period of time.

[0030] 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.

[0031] Example:

[0032] See also Figure 1 , a method for creating a local low-temperature environment of the kidney for laparoscopic surgery, comprising:

[0033] Pre-place 500-1000 ml of ice mud into the patient's body cavity and around the kidney through the 12 mm TROCAR hole;

[0034] Real-time monitoring of temperature changes in the perirenal surgical area to prevent the temperature from rising or falling too low;

[0035] Adjust the frequency and amount of ice mud injection according to the temperature changes in the perinephric surgical area.

[0036] According to the method of the present invention, during the operation, 10 ml of ice mud is pre-placed into the kidney periphery of the patient's body cavity through the 12 mm TROCAR hole. The ice mud is a mixture of small-particle ice and ice water. The ice mud can absorb the heat of the perirenal tissue, reduce the temperature of the perirenal tissue, and maintain a low-temperature environment of the perirenal tissue for a certain period of time. The low-temperature environment can reduce the metabolic rate of the kidney, reduce warm ischemia-reperfusion injury during surgery, and maintain the activity of kidney cells, thereby effectively prolonging the blood flow blockage time of the kidney, obtaining a longer operation time, and reducing the risk of complications such as postoperative frostbite of the renal parenchyma, hypothermia, and excessive volume load by precisely controlling the temperature and injection amount of the ice mud. Moreover, the injected ice mud can also flush the tissue after melting, so that the surgical part of the tissue surface is fully exposed, which is beneficial to the operator's operation.

[0037] See also Figure 2-6 , an ice mud storage and transportation device, applied to a method for creating a local low-temperature environment of the kidney for laparoscopic surgery, comprising:

[0038] The ice slush storage unit is used to store ice slush. The ice slush needs to be made in a sterile environment, and includes an insulated box 1, a box cover 2 hinged on the insulated box 1, and a weighing device 3 fixedly installed inside the insulated box 1. The insulated box 1 is provided with an insulated pot 5 placed on the weighing device 3 for holding the ice slush;

[0039] The ice slurry conveying part is used to convey the ice slurry inside the heat preservation pot 5 to the outside, and includes an output pump 6 connected to the box cover 2 and an output pipe 7 fixedly installed at the output end of the output pump 6. The upper end of the output pipe 7 penetrates and extends to the top of the box cover 2. The output pipe 7 is sleeved with a guide pipe 10, and a fixing component for fixing the guide pipe 10 is provided;

[0040] The temperature monitoring unit is used to monitor the tissue temperature of the part of the patient's body cavity where the ice mud is pre-placed, and includes a wire 17 plugged into the box cover 2 and a temperature probe 18 connected to the end of the wire 17;

[0041] The control unit is used to receive the tissue temperature information of the preset ice mud position in the patient's body cavity collected by the temperature monitoring unit, and control the amount of ice mud output by the ice mud conveying unit according to the change of tissue temperature, including a controller 14 fixedly mounted on the box cover 2, and the controller 14 is connected to the output pump 6 and the wire 17.

[0042] As can be seen from the above, before the operation begins, the output pump 6 is started to pump the ice mud inside the insulation pot 5 into the output tube 7 and the guide tube 10 to fill the cavity inside the output tube 7 and the guide tube 10, and then the weight of the ice mud inside the insulation pot 5 is weighed by the weighing device 3, and the output pump 6 is started again to pump out about 10g of ice mud. At this time, the ice mud is transported to the renal area of ​​the patient's body cavity to be operated on through the guide tube 10. The operator can obtain the weight value of the ice mud inside the insulation pot 5 through the weighing value of the weighing device 3, and then determine the output ice mud amount. During the operation, the operator can obtain the temperature of the surgical site through the temperature probe 18 and the wire 17, so that the operator can replenish the ice mud immediately when the tissue temperature rises, and also avoid frostbite caused by excessive replenishment of ice mud, which may cause the tissue temperature to be too low and cause frostbite. The controller 14 can collect the information of the temperature probe 18, and then start the output pump 6 to pump out the ice mud according to the operator's instructions.

[0043] See also Figure 6 The heat exchange tube 4 surrounding the heat preservation pot 5 is arranged inside the heat preservation box 1. The heat exchange tube 4 can create a low temperature environment inside the heat preservation box 1 to prevent the ice mud inside the heat preservation box 1 from melting, so that the ice mud can remain in the ice mud state for a long time.

[0044] See also Figure 2-3 The fixing assembly includes a clip 8 fixedly mounted on the output tube 7, the clip 8 is tilted, and a tube 9 is threadedly connected to the output tube 7 and can be slidably abutted against the clip 8. When the guide tube 10 is sleeved on the output tube 7, the tube 9 can be slid against the clip 8, forcing the clip 8 to rotate and clamp the end of the output tube 7, so that the guide tube 10 is firmly sleeved on the output tube 7, and it is also convenient to remove the guide tube 10 for cleaning later.

[0045] In order to facilitate the surgeon to instantly control the injection of ice mud during the operation, a control handle 11 is fixedly connected to the end of the guide tube 10, and a switch 12 for controlling the start and stop of the output pump 6 is connected to the control handle 11. A catheter 13 for inserting into the patient's body cavity to insert ice mud is fixedly connected to the end of the control handle 11. The surgeon can hold the handle 11 and press the switch 12 to control the output pump 6 to start transporting ice mud outward. At this time, the display screen of the controller 14 can display the amount of output ice mud in real time, which is convenient for the surgeon to grasp the amount of ice mud required for the operation.

[0046] See also Figure 5-6The box cover 2 is provided with a speaker 15 and a prompt light 16 connected to the controller 14. The operator can set a certain time through the controller 14. After a certain time, the controller 14 can issue a prompt sound through the speaker 15 and control the prompt light 16 to flash, thereby prompting the operator to immediately replenish the injection of ice mud. At the same time, a temperature warning prompt program can be set. When the temperature probe 18 detects that the temperature of the tissue around the operation has returned to a certain value, the controller 14 can issue a prompt sound through the speaker 15 and control the prompt light 16 to flash, thereby prompting the operator to immediately replenish the injection of ice mud.

[0047] An electric valve for blocking the conduit 13 is arranged inside the control handle 11. The start and stop of the electric valve are consistent with the output pump 6 and are controlled by the switch 12. The electric valve can block the passage of the conduit 13 to prevent ice mud from flowing out of the conduit 13 and causing excessive injection of ice mud.
