Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a heating device for a laparoscopic lens. Background Technology

[0002] With the modernization of electronic medical device technology, laparoscopic technology is also constantly being improved. In particular, in recent years, laparoscopic technology has been widely used in fields such as gastrointestinal surgery to perform various surgeries, which has completely changed the traditional surgical concept.

[0003] Before the laparoscope is inserted into the abdominal cavity, the lens temperature is close to the operating room temperature, approximately 20°C to 25°C. After insertion, the laparoscope lens gradually warms up to body temperature (37°C). During this warming process, the lens fogs up, resulting in unclear images on the monitor and affecting the surgeon's operation. To maintain the temperature of the laparoscope during laparoscopic surgery, it is usually preheated by placing it in a thermos. However, this practice has the following problems:

[0004] Firstly, current thermos flasks have a single function. Hot salt water needs to be poured into the flask in advance. When preheating and keeping the laparoscope warm, the lid needs to be unscrewed and the laparoscope inserted into the thermos flask. This causes heat loss from the thermos flask and often results in hot salt water spilling out and burns. The hot salt water in the thermos flask also needs to be replaced after use due to heat loss.

[0005] Secondly, since there is no device to hold the laparoscope tube in the opening of the thermos, the tube often collides with the opening of the thermos after the laparoscope is inserted, causing damage to the laparoscope.

[0006] Thirdly, the water temperature inside the thermos cannot be clearly known to medical staff. If the temperature is too low or too high, it will not be conducive to achieving the purpose of heating the lens.

[0007] In summary, there is an urgent need to design a heating device for laparoscopic lenses that overcomes the aforementioned technical problems. Utility Model Content

[0062] The fixing component 2 includes a clamping fixing member 21 and a supporting fixing member 22; wherein:

[0063] The clamping and fixing member 21 is provided at the top of the heating cylinder 11 for clamping the rod part of the lens;

[0064] The support and fixing member 22 is located inside the heating cylinder 11 to support the head end of the lens.

[0065] A heating device for a laparoscopic lens according to an embodiment of this application, during use:

[0066] During preoperative preparation, medical staff place the heating base 12 in a suitable position on the surgical operating platform or embed it in the operating platform used in conjunction with it; then place the heating cylinder 11 containing an appropriate amount of physiological saline on the heating base 12, turn on the heating on / off knob 1261 and set its temperature; then the saline in the heating cylinder 11 will begin to heat until the appropriate temperature is reached.

[0067] When the surgery is in progress and the medical staff needs to heat the endoscope, first open the sealing cover 1122 on the cover 112, then open the clamping and fixing piece 21 appropriately, insert the endoscope through this piece and place it at the bottom mesh 222; finally, fasten the clamping arms 211 on both sides to ensure effective clamping and fixing of the endoscope; after insertion, press the timing button 1263, and the timer 124 will start timing. When the timer ends, the indicator light 128 will change from red to green, and the medical staff can then remove the endoscope;

[0068] When the surgery is over, the medical staff will turn off the electromagnetic switch 1262, and then the heating cylinder 11 can be quickly removed from the heating base 12 and sent for disinfection and sterilization so that it can be reused.

[0069] like Figure 2 As shown, a heating device for a laparoscopic lens according to the present invention includes a heating cylinder 11 which is cylindrical and includes a cylinder body 111 and a cover body 112 which is detachably screwed to it.

[0070] The heating cylinder 11 has heating wires 114 evenly distributed in the inner wall interlayer and a temperature sensor 113 is provided on its bottom wall.

[0071] The bottom end of the cylinder 111 is provided with a cylindrical electronic port 115, which is used in conjunction with the electronic plug 121 at the center of the heating base 12 to connect the cylinder 111 and the heating base 12 and realize data exchange.

[0074] In this embodiment of the heating device for a laparoscopic lens, it should be noted that the timer 124 can be set according to the current heating time of the laparoscopy, such as 60s, 90s, etc.; the specific time is not used as a limiting parameter here.

[0075] Meanwhile, the display screen 127 is used to display the real-time temperature of the liquid in the heating cylinder 11 monitored by the temperature sensor 113, so that it is kept within the preset range, such as 48-55 degrees Celsius; when the temperature rises to the set threshold, the heating wire 114 stops heating; when the temperature drops to the set threshold, the heating wire 114 turns on to heat; thereby achieving the purpose of heating and heat preservation.

[0076] The power supply unit 125 here can be equipped with a suitable rechargeable battery, which can be used for charging, thus ensuring that the device is easy to carry and avoids the inconvenience of connecting to a power source.

[0077] This application provides a heating device for a laparoscopic lens. The heating base 12 has various built-in control components. By setting these control components, the heating time and temperature can be controlled, thereby ensuring that the water temperature in the heating cylinder 11 is constant and meeting the needs of heating the laparoscopic lens.

[0078] like Figure 6 As shown, this utility model discloses a heating device for a laparoscopic lens, wherein the insert 1291 houses an electromagnet 1292, and the slot 117 houses a permanent magnet electrically connected to the electromagnet 1292; the electromagnet 1292 is electrically connected to the microprocessor 123.

[0079] This application provides a heating device for a laparoscopic lens, wherein the insertion post 1291 and the slot 117 are connected by electromagnetic adsorption; this can satisfy the connection between the heating cylinder 11 and the heating base 12.

[0080] like Figure 6As shown, a heating device for a laparoscopic lens according to the present invention includes a control button 126 comprising a heating on / off knob 1261, an electromagnetic switch 1262, and a timing button 1263; which are electrically connected to the microprocessor 123 respectively.

[0081] like Figure 4 As shown, a heating device for a laparoscopic lens of the present invention has a through hole 1121 at the center of the cover 112 and a sealing cover 1122 on it; a silicone pad 1123 is attached to the inner wall of the through hole 1121 and anti-slip particles are provided on the inner wall.

[0082] According to an embodiment of this application, a heating device for a laparoscopic lens is provided on the cover 112, which has a through hole 1121 with a sealing cover 1122, so that the laparoscopic lens can be inserted through the through hole 1121; thus avoiding the problem of water temperature drop caused by opening the cover 112.

[0083] like Figure 4 As shown, a heating device for a laparoscopic lens according to the present invention includes a clamping and fixing member 21 comprising clamping arms 211 and a semi-circular clamping ring 212 disposed on both sides; the clamping arms 211 are inverted L-shaped, one end of which is movably hinged to the left and right side walls of the cover, and the other end is connected to the clamping ring 212; the inner walls of the clamping rings 212 on both sides are provided with anti-slip pads 213, which can be attached to the rod of the lens.

[0084] This application provides a heating device for a laparoscopic lens, wherein the clamping and fixing member 21 is used to effectively clamp and fix the rod of the laparoscopic lens, avoiding the need for manual holding.

[0085] like Figure 4 As shown, in a heating device for a laparoscopic lens of this utility model, the clamping rings 212 on both sides are magnetically connected by magnetic strips 214 attached to the outer wall; the height of the anti-slip pad 213 is greater than the height of the clamping rings 212 and its inner wall is provided with a micro suction cup 215.

[0086] In a heating device for a laparoscopic lens according to an embodiment of this application, since the lenses have different thicknesses, the clamping rings 212 are connected by magnetic adsorption, so that even if the diameters of the clamped laparoscopic lenses are slightly different, the purpose of effective clamping can be achieved.

[0087] like Figure 5 As shown, a heating device for a laparoscopic lens according to the present invention includes a support and fixing member 22 horizontally placed inside the heating cylinder 11; and it includes a connecting ring 221 and a partition net 222 disposed in the middle; the connecting ring 221 is snapped onto a corresponding protrusion on the inner wall of the heating cylinder 11 and is made of heat-insulating material; the partition net 222 is made of silicone material.

[0088] According to an embodiment of this application, a heating device for a laparoscopic lens is provided. The supporting and fixing member 22 is placed inside the heating cylinder 11 and near its bottom end to support the head end of the laparoscopy lens, preventing its diameter from touching the inner wall of the heating cylinder 11 and avoiding unnecessary damage to the head end of the laparoscopy lens.

[0089] Example 2

[0090] Based on Example 1, please refer to Figure 9-10 In order to ensure that the lens can be used normally quickly after heating, a drying component 3 is also included. The drying component 3 is detachably connected to the outer wall of the heating cylinder 11 and electrically connected to the power supply component 125 in the heating base 12.

[0091] In this embodiment, a drying component 3 is provided. The drying component 3 is a cylindrical drying device, which is detachably provided on the outer wall of the heating cylinder 11 and electrically connected to the power supply component 125.

[0092] Specifically, the drying assembly 3 includes a cylindrical housing 31, a small dryer 32 located at the bottom of the cylindrical housing 31, and an air outlet 33 connected to the small dryer 32 via an air outlet pipe. The top of the cylindrical housing 31 has an opening 36 for inserting a lens, and a dustproof pad 37 is provided at the opening to prevent dust from entering. The dustproof pad 37 is petal-shaped and tightly fitted to the opening 36. When the lens is not inserted, it gathers together to block the opening 36 and prevent dust from entering. When the lens is inserted into the opening 36, the dustproof pad 37 is fitted against the outer wall of the lens and enters the drying chamber of the housing. After the lens is removed, the dustproof pad 37 returns to its original shape.

[0093] The dustproof pad 37 is preferably made of silicone material that is heat-resistant, wear-resistant and elastic. Its design not only ensures the cleanliness and sealing of the drying components, but also reduces the gap between the lens and the drying chamber to a certain extent, thereby improving drying efficiency.

[0094] It also includes a partition net 34 and a pad 35 laid on top of the partition net; the air outlet 33 is located below the partition net.

[0095] The lens is first heated in the heating cylinder 11 to remove surface moisture and fog. After heating, the lens is moved into the drying assembly 3 and placed on the mesh 34. The small dryer 32 is activated, generating hot air that is blown onto the lens surface through the air outlet 33. The mesh 34 prevents impurities from entering the dryer, while the pad 35 supports the lens and ensures the flow of hot air. The lens is quickly dried under the hot air until it is ready for normal use.

[0096] In this embodiment, the small dryer 32 is located at the bottom of the cylindrical housing 31 and is the core component of the drying assembly 3. It is electrically driven to generate hot air for drying the lens. The small dryer 32 has an adjustable temperature function so that the drying temperature can be adjusted according to the material of different lenses and drying requirements.

[0097] It should be noted that the outer wall of the drying component 3 is provided with an electrical plug that corresponds to the electrical socket on the heating base 12. When in use, the two can be connected. At the same time, the heating base 12 is also provided with a drying button 38 for controlling the opening and closing of the drying component. The recommended drying time is 3 minutes. The endoscope lens can be removed after the time is up and it will automatically stop.

[0098] It should be further explained that this design must ensure that the air temperature of the small dryer 32 is appropriate to avoid overheating and damaging the lens; it achieves effective cleaning, heating and rapid drying of the laparoscopic lens during surgery, thereby reducing the problem of lens fogging or condensation and ensuring the clarity of the surgical field of vision.

[0099] like Figure 2 As shown, this utility model discloses a heating device for a laparoscopic lens, wherein the outer wall of the heating cylinder 11 is provided with a transparent window 116; medical personnel can observe the insertion of the laparoscopic lens through this window.

[0100] like Figure 1 As shown, in a laparoscopic lens heating device of the present invention, the bottom wall of the heating base 12 is provided with a miniature suction cup or an anti-slip rubber pad to prevent displacement.

[0101] The present invention has been further described above with reference to the embodiments, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
