技术领域technical field
本实用新型涉及一种医疗器械，具体涉及一种带有防雾功能的腹腔镜。The utility model relates to a medical device, in particular to a laparoscope with an anti-fog function.
背景技术Background technique
腹腔镜是一种带有微型摄像头的手术器械，通过冷光源提供照明，将腹腔镜的镜头插入腹腔内，运用数字摄像技术将腹腔镜的镜头拍摄到的图像通过光导纤维传导至信号处理系统，并在显示器上显示，以辅助医生操作手术器械和进行腹腔内部的检查等。Laparoscope is a surgical instrument with a miniature camera, which provides illumination through a cold light source, inserts the lens of the laparoscope into the abdominal cavity, and uses digital camera technology to transmit the image captured by the lens of the laparoscope to the signal processing system through the optical fiber. And displayed on the monitor to assist the doctor to operate the surgical instrument and perform the inspection inside the abdominal cavity.
腹腔镜镜头一般为30°的斜面状，为了保证手术的顺利开展，保证手术质量，减少手术中的损伤，必须要有一个清晰的视野，那么就要求腹腔镜的镜头是清晰的。然而，由于手术室环境相对于人体体温低，腹腔镜镜头在探入腹腔中时，由于腹腔内外的温差较大，部分水蒸气遇到冷的腹腔镜后非常容易凝聚，而在镜头上形成一层雾，影响视野在显示器上的清晰度。The laparoscopic lens is generally in the shape of a 30° slope. In order to ensure the smooth progress of the operation, ensure the quality of the operation, and reduce the damage during the operation, it is necessary to have a clear field of vision, so the laparoscopic lens is required to be clear. However, since the environment of the operating room is lower than the body temperature of the human body, when the laparoscopic lens is inserted into the abdominal cavity, due to the large temperature difference between the inside and outside of the abdominal cavity, part of the water vapor is very easy to condense after encountering the cold laparoscope, and forms a cloud on the lens. A layer of fog that affects the clarity of the field of view on the display.
传统操作过程中，采用先预热镜头的方式，使腹腔镜在进入人体前预热到和人体相仿的温度，但这种方法在一定时间内有效，而一段时间后，腹腔镜表面仍会起雾，这时候就需要反复将腹腔镜拿出，而用碘伏溶液擦拭腹腔镜镜头后再探入腹腔中进行操作。In the traditional operation process, the method of preheating the lens is used first, so that the laparoscope is preheated to a temperature similar to that of the human body before entering the human body. However, this method is effective for a certain period of time, and after a period of time, the surface of the laparoscope will still rise. At this time, it is necessary to repeatedly take out the laparoscope, wipe the laparoscope lens with iodophor solution, and then insert it into the abdominal cavity for operation.
但是，腹腔镜在反复进入腹腔过程中，影响手术进行甚至耽误术中止血，增大手术风险；而镜头也需要反复清理，增加了创口感染的几率。However, when the laparoscope repeatedly enters the abdominal cavity, it will affect the operation and even delay intraoperative hemostasis, increasing the risk of the operation; and the lens also needs to be cleaned repeatedly, which increases the chance of wound infection.

具体实施方式Detailed ways
腹腔镜在使用过程中遇到不可避免的问题就是由于温差而在镜头1上产生的雾，传统的除雾和防雾方法均是需要在体外处理腹腔镜，如加热法、涂抹防雾剂等，但每次处理后均不能使用长久，一段时间后就需要取出腹腔镜重新处理；而反复拿出腹腔镜极易延长手术时间及提高手术风险，因此应在使用过程中尽量减少腹腔镜拿出次数。The inevitable problem encountered in the use of laparoscope is the fog generated on the lens 1 due to the temperature difference. The traditional defogging and anti-fog methods all need to treat the laparoscope outside the body, such as heating method, applying anti-fog agent, etc. , but it cannot be used for a long time after each treatment, and the laparoscope needs to be taken out for reprocessing after a period of time; taking out the laparoscope repeatedly can easily prolong the operation time and increase the risk of surgery, so it should be minimized during use. frequency.
本实用新型根据上述要求，提供了一种能在体内进行镜头1上积雾处理的腹腔镜：According to the above requirements, the utility model provides a laparoscope capable of treating the fog accumulation on the lens 1 in the body:
一种带有防雾功能的腹腔镜，包括腹腔镜，所述的腹腔镜前端的镜头1侧面开设有喷射孔11，在腹腔镜镜管2的管壁中沿镜管2轴向开设有用于向喷射孔11供给防雾剂的导液槽3，导液槽3与装有防雾剂的推进器5连接。A laparoscope with an anti-fog function, comprising a laparoscope, the side of the lens 1 at the front end of the laparoscope is provided with a spray hole 11, and in the tube wall of the laparoscope tube 2 along the axial direction of the tube 2 is provided a The liquid guide tank 3 that supplies the anti-fogging agent to the injection hole 11 is connected to the impeller 5 that is equipped with the anti-fogging agent.
本实用新型的使用原理是，通过喷射孔11向镜头1上喷射防雾剂，如碘伏溶液、盐水等对于人体低害或无害的药品，这些药品具有良好的防雾效果，同时喷射时也能使镜头1得到冲洗，使视野更加干净清晰；优选采用盐水。The principle of use of the utility model is to spray anti-fogging agent on the lens 1 through the injection hole 11, such as iodophor solution, salt water and other medicines that are low or harmless to the human body. The lens 1 can also be washed to make the field of view cleaner and clearer; preferably, salt water is used.
向喷射孔11提供防雾剂的通道是设置在腹腔镜镜管2管壁中的导液槽3，沿着镜管2轴向设置，将液体通过推进器5导向到喷射孔11中。推进器5可以有多种结构，如气压式、手动式、按压式、电动式等，只要能将液体向一个方向推动即可。The channel for supplying the antifogging agent to the injection hole 11 is the liquid guide groove 3 arranged in the tube wall of the laparoscope tube 2 , which is arranged along the axial direction of the mirror tube 2 , and guides the liquid into the injection hole 11 through the propeller 5 . The propeller 5 can have various structures, such as air pressure type, manual type, push type, electric type, etc., as long as the liquid can be pushed in one direction.
为了使防雾剂的使用效果更好：In order to make the use of anti-fog agent better:
喷射孔11分布在腹腔镜镜头1最前端一侧，喷射孔11分布范围对应的圆心角不小于60°，并且每个喷射孔11中喷射出防雾剂的喷洒范围不小于120°。The injection holes 11 are distributed on the front end side of the laparoscopic lens 1, the central angle corresponding to the distribution range of the injection holes 11 is not less than 60°, and the spraying range of the antifogging agent sprayed from each injection hole 11 is not less than 120°.
镜头1一般为30°的斜面，镜头1的最前端是指镜头1前部与镜管2末端距离最远的部分；喷射孔11设置在镜头1的侧面，以使其喷出的液体能直接冲向镜头1上；而通过对喷射孔11形状的设置，如将喷射孔11的前端设置为120°的开口，那么喷出的液体范围也就不小于120°；这样相邻的两个喷射孔11之间在防雾剂进行喷洒时能部分交叠，相互作用，起到完全覆盖并能有一定的冲洗强度，保持镜头1的干净，同时也均匀地涂上了一层防雾剂。由于相邻的喷射孔11喷出的范围交叠，并且防雾剂会沿着镜头1流动，因此不需要设置过多的喷射孔11，喷射孔11仅需要沿镜头1的边缘分布一部分即可，而这个分布范围对应的圆心角不小于60°即可，这样就能达到良好的冲洗和覆盖范围。Lens 1 is generally a slope of 30°, and the front end of lens 1 refers to the part farthest from the front of lens 1 and the end of mirror tube 2; the spray hole 11 is arranged on the side of lens 1, so that the liquid ejected from it can be directly Rush towards the lens 1; and by setting the shape of the spray hole 11, as the front end of the spray hole 11 is set as an opening of 120°, the range of the sprayed liquid is not less than 120°; When the anti-fogging agent is sprayed, the holes 11 can partially overlap and interact to achieve complete coverage and a certain flushing strength to keep the lens 1 clean, and at the same time, a layer of anti-fogging agent is evenly coated. Since the ejection ranges of adjacent injection holes 11 overlap, and the antifogging agent will flow along the lens 1, there is no need to set too many injection holes 11, and only a part of the injection holes 11 need to be distributed along the edge of the lens 1. , and the central angle corresponding to this distribution range is not less than 60°, so that good flushing and coverage can be achieved.
导液槽3至少设置一对，导液槽3后端与设置在镜管2后端管壁中的储液腔14连通，导液槽3前端与设置在靠近镜管2上靠近镜头1一端管壁中的加压腔13连接，加压腔13上连通有通向不同喷射孔11的供液管12。At least one pair of liquid guide grooves 3 is provided, the rear end of the liquid guide groove 3 communicates with the liquid storage cavity 14 arranged in the wall of the rear end of the mirror tube 2, and the front end of the liquid guide groove 3 is connected to the end close to the lens 1 on the mirror tube 2 The pressurized chamber 13 in the tube wall is connected, and the pressurized chamber 13 is connected with a liquid supply pipe 12 leading to different injection holes 11 .
由于需要给喷射出的防雾剂一定的压力，因此设置了储液腔14和加压腔13结构：储液腔14是防雾剂刚进入镜管2管壁的部位，具有一定的空间，能容纳一部分防雾剂，前端的加压腔13与储液腔14对应，加压腔13远较供液管12的直径大，这样在后端不断推进防雾剂时，加压腔13中的防雾剂能以较大的压力从供液管12中进入喷射孔11，达到良好的喷洒效果。设置至少一对导液槽3可以使压力能有更好的传递，同时便于防雾剂的输送。Because it is necessary to give the sprayed antifogging agent a certain pressure, the structure of the liquid storage chamber 14 and the pressurization chamber 13 is provided: the liquid storage chamber 14 is the part where the antifogging agent has just entered the wall of the mirror tube 2, and has a certain space. It can accommodate a part of the anti-fogging agent. The pressurized chamber 13 at the front corresponds to the liquid storage chamber 14. The diameter of the pressurized chamber 13 is far larger than that of the liquid supply pipe 12. In this way, when the anti-fogging agent is continuously advanced at the rear end, the pressurized chamber 13 The anti-fogging agent can enter the injection hole 11 from the liquid supply pipe 12 with relatively high pressure, so as to achieve a good spraying effect. The provision of at least one pair of liquid guide grooves 3 can make the pressure transfer better and at the same time facilitate the delivery of the anti-fogging agent.
供液管12最好沿着镜管2轴向设置，设置方向和防雾剂推进的压力方向相同，这样使防雾剂液体有更大的压力。The liquid supply pipe 12 is preferably arranged axially along the mirror tube 2 in the same direction as the pressure direction of the antifogging agent, so that the antifogging agent liquid has a greater pressure.
镜管2外壁上设置有与储液腔14连通的用于和推进器5连接的连接管15。The outer wall of the mirror tube 2 is provided with a connecting pipe 15 communicating with the liquid storage chamber 14 for connecting with the propeller 5 .
连接管15可便于和不同的推进器5对接，以安装推进器5。The connecting pipe 15 can facilitate docking with different propellers 5 to install the propellers 5 .
推进器5采用带有刻度6的注射器，注射器利用软管4与连接管15连接。The propeller 5 adopts a syringe with a scale 6, and the syringe is connected with a connecting pipe 15 by a hose 4.
推进器5可以采用多种结构，本例中给出一种简单、常用由非常有效的推进器5——注射器。注射器的直径比镜管2直径大，能产生理想的推进压力。而且注射器上有刻度6值，当其中装入防雾剂后，可提前通过试验，确定推进多少防雾剂既能达到清洗镜头1的目的，又能将镜头1完全覆盖，这样就尽可能地监控和减少了防雾剂的用量。Propeller 5 can adopt multiple structures, and a kind of simple, commonly used by very effective propeller 5---syringe is provided in this example. The diameter of the syringe is larger than the diameter of the mirror tube 2, which can produce ideal pushing pressure. Moreover, there is a scale 6 on the syringe. When the anti-fogging agent is loaded into it, the test can be passed in advance to determine how much anti-fogging agent can be pushed to achieve the purpose of cleaning the lens 1 and completely cover the lens 1, so that as much as possible The amount of anti-fogging agent is monitored and reduced.
该腹腔镜使用前，应先接上推进器5，推进一部分防雾剂，将导液槽3、储液腔14、加压腔13中的空气排除，使其中充满防雾剂，然后再进行体内操作；体内需要清理镜头1雾气时，最好先将镜管2旋转使镜头1最前端在上，再进行喷防雾剂操作，使防雾剂能在喷洒后自然从镜面上流动。Before this laparoscope is used, the propeller 5 should be connected earlier, and a part of antifogging agent should be advanced, and the air in the liquid guide tank 3, liquid storage chamber 14, and pressurizing chamber 13 should be removed, so that the antifogging agent is filled therein, and then In vivo operation: When the lens 1 fog needs to be cleared in the body, it is best to rotate the mirror tube 2 so that the front end of the lens 1 is on top, and then spray the anti-fogging agent so that the anti-fogging agent can flow naturally from the mirror surface after spraying.
