Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, to a temperature-controlled surgical incision protection device. Background Art

[0002] A surgical incision protection device is a surgical auxiliary device, and its core component is an incision protection sleeve, which is used to protect the soft tissues around the incision from being injured or torn, and at the same time enables surgical instruments such as a thoracic cavity lens to enter and exit during the operation, avoiding the direct entry of surgical instruments into the incision, interfering with the operation process or damaging organs.

[0003] However, during the operation, the temperature of the incision, such as the temperature of the human thoracic cavity, is often higher than the temperature inside the incision protection sleeve, and the surgical instruments inside the incision protection sleeve are prone to fogging. For example, for a thoracic cavity lens placed inside the incision protection sleeve, its temperature is lower than the temperature of the human thoracic cavity, and the fog in the thoracic cavity condenses into small water droplets on the surface of the lens, resulting in a blurred image, inconvenient operation, and low safety.

[0004] In summary, how to solve the problem that the surgical instruments inside the incision protection sleeve are prone to fogging, resulting in inconvenient operation and low safety, is an urgent problem to be solved by those skilled in the art at present. Content of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a temperature-controlled surgical incision protection device, which can realize self-temperature adjustment to avoid fogging of surgical instruments and improve the convenience and safety of operation.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A temperature-controlled surgical incision protection device includes an incision protection sleeve, an intake pipe, a heater, a temperature sensor, and a temperature controller. The inner cavity of the incision protection sleeve is used to accommodate surgical instruments. The first end of the intake pipe is connected to a gas source for supplying inert gas, and the second end is inserted into the inner cavity of the incision protection sleeve. The heater is arranged on the intake pipe and is used to adjust the temperature of the inert gas. The temperature sensor is arranged in the inner cavity of the incision protection sleeve and is used to sense the temperature of the inner cavity of the incision protection sleeve. The temperature controller is electrically connected to the temperature sensor and the heater, and the temperature controller is used to control the heater to adjust the temperature of the inert gas.

[0008] Preferably, a pressure controller is arranged on the intake pipe between the gas source and the heater for adjusting the air pressure of the inert gas.

[0009] Preferably, a filter is arranged on the intake pipe between the pressure controller and the heater for filtering the inert gas.

[0010] Preferably, an air injection valve is provided on the intake pipe located between the heater and the incision protection sleeve for controlling the on-off of the intake pipe.

[0011] Preferably, the second end of the intake pipe is disposed near the bottom of the incision protection sleeve.

[0012] Preferably, an annular pipe is provided at the bottom of the inner cavity of the incision protection sleeve. The second end of the intake pipe is communicated with the annular pipe, and a nozzle is provided on the annular pipe.

[0013] Preferably, a plurality of the nozzles are uniformly arranged along the annular pipe and are all inclined towards the central axis of the incision protection sleeve.

[0014] Preferably, an air extractor and an exhaust pipe are further included. The first end of the exhaust pipe is inserted into the inner cavity of the incision protection sleeve, and the second end extends out of the incision protection sleeve and is connected to the air extractor.

[0015] Preferably, an exhaust valve is provided on the exhaust pipe located between the air extractor and the incision protection sleeve.

[0016] Preferably, the first end of the exhaust pipe is communicated with the annular pipe.

[0017] When the temperature-controlled surgical incision protection device provided by the present invention is in use, surgical instruments such as a thoracic cavity lens are placed in the inner cavity of the incision protection sleeve.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] The core of the present utility model is to provide a temperature-controlled surgical incision protection device, which can realize self-temperature adjustment to avoid the fogging of surgical instruments and improve the convenience and safety of operation.

[0026] It should be noted that in this embodiment, the orientation or positional relationship indicated by "upper", "lower", "front", "rear", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present application.

[0027] Please refer to Figure 1 , the application provides a temperature-controlled surgical incision protection device, including a cut protection sleeve 1, an intake pipe 2, a heater 3, a temperature sensor 4 and a temperature controller 5. The inner cavity of the cut protection sleeve 1 is used to accommodate surgical instruments. The first end of the intake pipe 2 is connected to a gas source for supplying inert gas, and the second end is inserted into the inner cavity of the cut protection sleeve 1. The heater 3 is arranged on the intake pipe 2 for adjusting the temperature of the inert gas. The temperature sensor 4 is arranged in the inner cavity of the cut protection sleeve 1 for sensing the temperature of the inner cavity of the cut protection sleeve 1. The temperature controller 5 is electrically connected to the temperature sensor 4 and the heater 3, and the temperature controller 5 is used to control the heater 3 to adjust the temperature of the inert gas.

[0028] The incision protection sheath 1 is used to protect the human incision during the operation. Surgical instruments enter and exit the incision protection sheath 1. An air inlet pipe 2 is inserted into the inner cavity of the incision protection sheath 1, and the air inlet pipe 2 extends out of the inner cavity of the incision protection sheath 1 and is connected to an external gas source. The gas source can be a gas storage device for supplying inert gas, such as carbon dioxide, which is not likely to cause other chemical reactions, does not cause much smoke, does not affect the surgical field of view, and ensures human safety.

[0029] The temperature sensor 4 is arranged in the inner cavity of the incision protection sheath 1 and is connected to a temperature controller 5 placed outside the incision protection sheath 1 through a medical wire. The temperature sensor 4 is used to sense the temperature of the inner cavity of the incision protection sheath 1 and transmit it to the temperature controller 5.

[0030] The heater 3 is arranged on the air inlet pipe 2 extending out of the incision protection sheath 1 and is connected to the temperature controller 5 through a medical wire. The heater 3 is used to adjust the temperature of the inert gas in the air inlet pipe 2. It should be noted that the heater 3 has different heating gears, and the temperature controller 5 can control the heater 3 to heat the inert gas at a suitable heating gear according to the temperature difference between the temperature of the inner cavity of the incision protection sheath 1 and the temperature of the surgical site.

[0031] Therefore, when the temperature-controlled surgical incision protection device provided by the present utility model is in use, the temperature sensor 4 senses the temperature of the inner cavity of the incision protection sheath 1 and transmits it to the temperature controller 5. After the temperature controller 5 obtains the inner cavity temperature and compares it with the temperature of the surgical site, such as the thoracic cavity temperature, if the inner cavity temperature is lower than the thoracic cavity temperature, it controls the heater 3 to heat up, so as to increase the temperature of the inert gas introduced into the inner cavity of the incision protection sheath 1 to increase the inner cavity temperature, thereby reducing the temperature difference between the inner cavity temperature and the thoracic cavity temperature, so as to prevent the surgical instruments placed in the inner cavity of the incision protection sheath 1 from fogging, especially improving the picture clarity of surgical imaging equipment such as thoracic cavity lenses, thereby improving the convenience and safety of the operation.

[0032] On the basis of the above embodiment, please refer to Figure 1 , a pressure controller 6 is arranged on the air inlet pipe 2 between the gas source and the heater 3 for adjusting the air pressure of the inert gas.

[0033] It can be understood that the flow rate of the inert gas introduced into the inner cavity of the incision protection sheath 1 is related to the air pressure of the inert gas in the air inlet pipe 2. Thus, the pressure controller 6 is arranged on the air inlet pipe 2, and the flow rate of the inert gas introduced into the inner cavity of the incision protection sheath 1 can be regulated by controlling the air pressure of the inert gas injected into the air inlet pipe 2 by the gas source, so as to achieve the purpose of controllable adjustment efficiency of the temperature of the inner cavity of the incision protection sheath 1.

[0034] Preferably, the pressure controller 6 is electrically connected to the temperature controller 5, and the temperature controller 5 is used to control the valve opening of the pressure controller 6 according to the internal cavity temperature of the incision protection sleeve 1. Specifically, after the temperature controller 5 obtains the internal cavity temperature and compares it with the surgical site temperature, if the temperature difference between the internal cavity temperature and the surgical site temperature is large, the valve opening of the pressure controller 6 can be increased to reduce the inert gas pressure, thereby increasing the inert gas flow rate, so that more inert gas can be quickly introduced into the internal cavity of the incision protection sleeve 1 to quickly reduce the temperature difference between the internal cavity temperature and the surgical site temperature, thus greatly avoiding the fogging of the surgical instruments placed in the internal cavity of the incision protection sleeve 1.

[0035] Based on the above embodiments, please refer to Figure 1 , a filter 7 is provided on the intake pipe 2 between the pressure controller 6 and the heater 3. The filter 7 can filter the inert gas delivered by the pressure control device to filter out harmful substances and impurities in the inert gas and prevent damage to the human body.

[0036] Based on the above embodiments, please refer to Figure 1 , an air injection valve 8 is provided on the intake pipe 2 between the heater 3 and the incision protection sleeve 1 for controlling the on-off of the intake pipe 2.

[0037] It can be understood that controlling the valve opening of the air injection valve 8 can also achieve the effect of adjusting the inert gas flow rate. When the overall device is running, if either the air injection valve 8 or the pressure control device fails to operate, the other can ensure that the inert gas flow rate is controllable and adjustable, thereby improving the reliability and stability of the overall device.

[0038] Based on the above embodiments, please refer to Figure 2 and Figure 3 , the second end of the intake pipe 2 is arranged close to the bottom of the incision protection sleeve 1. It should be noted that the bottom of the incision protection sleeve 1 is close to the incision, and the temperature difference between the bottom of the incision protection sleeve 1 and the surgical site is large. Therefore, the part of the surgical instrument at the bottom of the incision protection sleeve 1 is prone to fogging first. In this way, the end of the intake pipe 2 inserted into the incision protection sleeve 1 is arranged adjacent to the incision protection sleeve 1, so that the inert gas in the intake pipe 2 can be first injected into the bottom of the incision protection sleeve 1, which can not only quickly heat up the surgical instruments such as the thoracic cavity lens at the bottom of the incision protection sleeve 1 to ensure the normal progress of subsequent operations, but also enable the inert gas to diffuse from bottom to top into the internal cavity of the incision protection sleeve 1, improving the heating effect of the incision protection sleeve 1, that is, effectively reducing the temperature difference between the incision protection sleeve 1 and the surgical site.

[0039] Based on the above embodiments, please refer to Figure 3 , a circular pipe 9 is provided at the bottom of the internal cavity of the incision protection sleeve 1. The second end of the intake pipe 2 is communicated with the circular pipe 9, and a nozzle 10 is provided on the circular pipe 9.

[0040] Specifically, the annular tube 9 is circumferentially arranged at the bottom of the inner cavity of the incision protection sleeve 1. The intake pipe 2 is inserted into the end of the incision protection sleeve 1 and communicated with the inner cavity of the annular tube 9, and the inner cavity of the annular tube 9 is communicated with the nozzle 10. In this way, the heated inert gas first flows into the annular tube 9 through the intake pipe 2, and then the inert gas in the annular tube 9 is sprayed into the inner cavity of the incision protection sleeve 1 through the nozzle 10. Since the nozzle 10 has the characteristics of fast spraying speed and wide spraying range, and the annular tube 9 has a certain function of transitional gas storage, the inert gas can be quickly and fully diffused into the inner cavity of the incision protection sleeve 1 to improve the adjustment efficiency of the temperature in the inner cavity of the incision protection sleeve 1.

[0041] Further, please refer to Figure 1 With Figure 3 , a plurality of nozzles 10 are uniformly arranged on the annular tube 9, which can increase the flow rate of the inert gas introduced into the inner cavity of the incision protection sleeve 1, so as to greatly improve the adjustment efficiency of the temperature in the inner cavity of the incision protection sleeve 1.

[0042] Preferably, please refer to Figure 3 , the nozzle 10 is inclined towards the central axis of the incision protection sleeve 1. Since surgical instruments such as a thoracoscope are located at the bottom of the incision protection sleeve 1 during the operation to detect the incision morphology, the nozzle 10 is located at the bottom of the incision protection sleeve 1 and arranged towards the central axis, so that the inert gas can jet towards the thoracoscope to blow and clean the lens, thereby further improving the picture clarity of surgical imaging devices such as a thoracoscope.

[0043] It should be noted that since the bottom of the incision protection sleeve 1 has a through hole for the surgical instrument to pass through and communicate with the surgical site, the inner cavity of the incision protection sleeve 1 is communicated with the surgical site such as the inside of the chest. The inert gas will come into contact with the surgical site and be contaminated into waste gas. Therefore, after the inert gas raises the temperature in the inner cavity of the incision protection sleeve 1, the inert gas needs to be discharged, that is, the incision protection sleeve 1 needs to be ventilated.

[0044] To realize the ventilation of the incision protection sleeve 1, on the basis of the above embodiment, please refer to Figure 1 , the present application further includes an air extractor 11 and an air extraction pipe 12. The first end of the air extraction pipe 12 is inserted into the inner cavity of the incision protection sleeve 1, and the second end extends out of the incision protection sleeve 1 and is connected to the air extractor 11.

[0045] In this way, the air extractor 11 is turned on, and the inert gas is discharged from the incision protection sleeve 1 through the air extraction pipe 12. After a period of time, this time interval can be determined according to the time required to exhaust the air in the incision protection sleeve 1. Then, the pressure control device is turned on. The temperature controller 5 obtains the temperature of the temperature sensor 4 and adjusts the temperature increase of the heater 3 according to the obtained temperature, so as to inject inert gas at a reasonable temperature into the incision protection sleeve 1, thereby completing the air replacement of the incision protection sleeve 1. This can not only prevent the inert gas from being placed in the incision protection sleeve 1 for a long time and contaminating the surgical instruments after contacting the wound, but also continuously inject inert gas at a suitable temperature into the inner cavity of the incision protection sleeve 1 to better control the temperature of the inner cavity of the incision protection sleeve 1.

[0046] Preferably, please refer to Figure 1 , an exhaust valve 13 is provided on the air extraction pipe 12 between the air extractor 11 and the incision protection sleeve 1, so as to conveniently adjust the exhaust flow rate of the inert gas by controlling the valve opening of the exhaust valve 13, thereby realizing controllable and adjustable exhaust efficiency.

[0047] Based on any of the above embodiments, please refer to Figure 3 , the first end of the air extraction pipe 12 is communicated with the annular pipe 9. Specifically, the end of the air extraction pipe 12 inserted into the incision protection sleeve 1 is communicated with the annular pipe 9. In this way, the inert gas in the incision protection sleeve 1 can be quickly sucked into the annular pipe 9 through a plurality of nozzles 10, and then discharged outside the incision protection sleeve 1 through the annular pipe 9. Thus, the air extraction pipe 12 and the air inlet pipe 2 share the annular pipe 9 and the nozzles 10 to communicate with the inner cavity of the incision protection sleeve 1, which can not only realize the rapid gas injection and exhaust in the inner cavity of the incision protection sleeve 1, that is, realize the rapid air replacement of the incision protection sleeve 1, but also save the installation space in the inner cavity of the incision protection sleeve 1.
