技术领域Technical Field

本实用新型涉及医疗用具技术领域，尤其涉及一种用于白内障手术的撕囊标记装置。The utility model relates to the technical field of medical appliances, in particular to a capsulorhexis marking device used for cataract surgery.

背景技术Background Art

白内障是常见的致盲性眼病，手术是目前公认唯一有效的治疗手段，在白内障的手术过程中，撕囊是相当重要的一个步骤，撕囊是把混浊的晶状体的前囊膜撕去一个囊盖，将混浊的晶状体取出，然后进行人工晶体植入的一个必要手段，可以说，如果撕囊成功了，那么手术就基本接近于成功一大半，撕囊是对医生白内障手术技术的一个非常重要的考验。Cataract is a common blinding eye disease. Surgery is currently recognized as the only effective treatment. Capsulotomy is a very important step in cataract surgery. Capsulotomy is a necessary means to tear off the anterior capsule of the cloudy lens, remove the cloudy lens, and then implant an artificial lens. It can be said that if the capsulotomy is successful, then the operation is basically close to success. Capsulotomy is a very important test of the doctor's cataract surgery skills.

在临床上，既往的白内障手术一般会采取人工撕囊，撕囊结束后将人工晶体从撕囊口植入前囊内，由于人工晶体的标准形状为圆形且要植入前囊膜中间的位置，这要求对撕囊口形状大小和位置的把控极其精准，导致采用人工撕囊的难度较高，医护人员只能凭借自身的经验尽可能标准的进行撕囊，若是医护人员的经验较低或状态不佳，很容易造成撕囊口的形状不规则或是大小不一，甚至撕囊口的位置出现偏差，这会对后续人工晶体的植入造成很大影响，增加了医护人员的植入难度，大大降低了手术的成功率。In clinical practice, previous cataract surgeries generally use manual capsulotomy, after which an artificial lens is implanted into the anterior capsule through the capsulotomy opening. Since the standard shape of an artificial lens is round and it must be implanted in the middle of the anterior capsule, this requires extremely precise control of the shape, size and position of the capsulotomy opening, resulting in high difficulty in manual capsulotomy. Medical staff can only rely on their own experience to perform the capsulotomy as standard as possible. If the medical staff has little experience or is in poor condition, it is easy to cause the capsulotomy opening to be irregular in shape or size, or even have a deviation in position, which will have a great impact on the subsequent implantation of the artificial lens, increase the difficulty of implantation for medical staff, and greatly reduce the success rate of the operation.

具体实施方式DETAILED DESCRIPTION

为使本实用新型的目的、技术方案和优点更加清楚，下面将结合本实用新型具体实施例及相应的附图对本实用新型技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本实用新型一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型保护的范围。In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

以下结合附图，详细说明本实用新型各实施例提供的技术方案。The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

本实用新型实施例提供一种用于白内障手术的撕囊标记装置，包括手柄1和定位环2，所述手柄1上设有防滑纹，所述定位环2位于手柄1的一端，所述定位环2的内部设有辅助定位环21，所述定位环2底部的内侧壁设有多个连接杆22，所述定位环2下方设有标记组件3，所述标记组件3包括具备储存和析出染液功能的标记环31，所述标记环31位于多个连接杆22的底端且与多个连接杆22呈固定连接，所述标记组件3还包括用于对患者撕囊部位进行标记的标记舌32，所述标记舌32位于标记环31的底部；The present invention provides a capsulorhexis marking device for cataract surgery, comprising a handle 1 and a positioning ring 2, wherein the handle 1 is provided with anti-slip grooves, the positioning ring 2 is located at one end of the handle 1, an auxiliary positioning ring 21 is provided inside the positioning ring 2, a plurality of connecting rods 22 are provided on the inner side wall of the bottom of the positioning ring 2, a marking assembly 3 is provided below the positioning ring 2, the marking assembly 3 comprises a marking ring 31 with the function of storing and precipitating dye solution, the marking ring 31 is located at the bottom ends of the plurality of connecting rods 22 and is fixedly connected to the plurality of connecting rods 22, the marking assembly 3 further comprises a marking tongue 32 for marking the patient's capsulorhexis site, the marking tongue 32 is located at the bottom of the marking ring 31;

使用时，可手握手柄1上设有的防滑纹部位，将定位环2移动至与患者的角膜相对应处，再通过定位环2为环形形状可将定位环2与患者的角膜缘尽量处于圆心同轴位置，以此来对患者撕囊口的部位进行定位，此时，可在定位环的垂直方向向下继续移动手柄1，使得定位环2在移动过程中与患者的角膜缘始终保持圆心同轴的位置，直至定位环2下方的标记组件3与患者的角膜相接触，进而将标记舌32置于患者的角膜处，通过标记环31析出的染液可对其底部的标记舌32进行上色，其中，染液可为2％台盼蓝等具有染色且对人体无害的液体，标记舌32可为碳纤维等具有一定吸附性且对人体无害的产品；When in use, the anti-slip pattern portion of the handle 1 can be gripped by hand to move the positioning ring 2 to a position corresponding to the patient's cornea. The positioning ring 2 is annular in shape, so that the positioning ring 2 and the patient's corneal limbus can be placed as coaxially as possible with the center of the circle, so as to locate the position of the patient's capsulorhexis opening. At this time, the handle 1 can be further moved downward in the vertical direction of the positioning ring, so that the positioning ring 2 and the patient's corneal limbus always maintain a coaxial position with the center of the circle during the movement, until the marking component 3 below the positioning ring 2 contacts the patient's cornea, and then the marking tongue 32 is placed on the patient's cornea. The dye precipitated by the marking ring 31 can be used to color the marking tongue 32 at its bottom, wherein the dye can be a liquid with dyeing and harmless to the human body, such as 2% trypan blue, and the marking tongue 32 can be a product with certain adsorption and harmless to the human body, such as carbon fiber;

至此，可轻压定位环2，使得标记环31底端的标记舌32对患者角膜产生一定的压力，进而将沾染染液的标记舌32在患者的角膜上进行着色，患者角膜的着色部位形成一个圆圈标记，该圆圈标记即为撕囊口的标记部位，本装置通过定位环2与标记组件3之间的配合，可在患者前囊膜的中央部位形成一个圆形撕囊标记，在术中撕囊时为医护人员提供精准的撕囊部位标记，便于医护人员撕出形状规则为圆形且位置较为标准的撕囊口，降低人工撕囊的难度，为后续人工晶体的植入提供一定的保障。At this point, the positioning ring 2 can be lightly pressed so that the marking tongue 32 at the bottom of the marking ring 31 exerts a certain pressure on the patient's cornea, and then the marking tongue 32 stained with the dye is colored on the patient's cornea, and the colored part of the patient's cornea forms a circle mark, which is the marking part of the capsulotomy opening. Through the cooperation between the positioning ring 2 and the marking component 3, the device can form a circular capsulotomy mark in the central part of the patient's anterior capsule, and provide medical staff with an accurate capsulotomy position mark when tearing the capsulotomy during surgery, so that medical staff can tear out a capsulotomy opening with a regular circular shape and a relatively standard position, thereby reducing the difficulty of artificial capsulotomy and providing a certain guarantee for the subsequent implantation of an artificial lens.

本实用新型进一步较佳实施例中，所述定位环2与标记组件3及多个连接杆22的中心均为圆心同轴设置，当定位环2与患者的角膜缘处于相对应的位置时，对定位环2进行观察，通过定位环2与标记组件3及多个连接杆22的中心均为圆心同轴设置，标记组件3与多个连接杆22的中心均保持同轴位置对应，进而使得标记组件3能够准确的对撕囊位置进行标记，可避免定位环2对患者撕囊部位进行定位后，标记组件3的位置出现偏差，导致标记组件3无法对撕囊口的位置进行准确标记，对后续人工晶体的植入造成一定影响。In a further preferred embodiment of the utility model, the centers of the positioning ring 2, the marking component 3 and the multiple connecting rods 22 are all coaxially arranged. When the positioning ring 2 and the patient's corneal limbus are in corresponding positions, the positioning ring 2 is observed. Since the centers of the positioning ring 2, the marking component 3 and the multiple connecting rods 22 are all coaxially arranged, the centers of the marking component 3 and the multiple connecting rods 22 maintain coaxial position correspondence, so that the marking component 3 can accurately mark the capsulotomy position, which can avoid the position deviation of the marking component 3 after the positioning ring 2 locates the patient's capsulotomy site, resulting in the marking component 3 being unable to accurately mark the position of the capsulotomy opening, causing a certain impact on the subsequent implantation of an artificial lens.

本实用新型进一步较佳实施例中，所述标记环31的内部贯穿设有填充腔4，所述填充腔4的底端延伸至标记舌32的顶端，使用时，可在标记环31的填充腔4内填充粘附一定存量染液的海绵等具有吸附液体功能的材质，通过填充腔4的底端延伸至标记舌32的顶端，粘附有一定存量染液的海绵可将染液析出至标记舌32上，以此来对标记舌32进行上色，便于后续对撕囊位置进行标记。In a further preferred embodiment of the utility model, a filling cavity 4 is provided through the interior of the marking ring 31, and the bottom end of the filling cavity 4 extends to the top end of the marking tongue 32. When in use, a material with liquid absorption function such as a sponge with a certain amount of dye adhered to it can be filled in the filling cavity 4 of the marking ring 31. The sponge with a certain amount of dye adhered to it can precipitate the dye onto the marking tongue 32 through the bottom end of the filling cavity 4 extending to the top end of the marking tongue 32, so as to color the marking tongue 32, which is convenient for subsequent marking of the capsulorhexis position.

本实用新型进一步较佳实施例中，所述辅助定位环21的中心与定位环2为圆心同轴设置，在利用定位环2对患者的撕囊位置进行定位时，由于不同患者角膜缘的大小存在一定差异，若是定位环2的内径与患者角膜缘的偏差过大，会对撕囊位置的定位造成一定的误差，此时，可通过定位环2的内部设有辅助定位环21的中心与定位环2为圆心同轴设置，观察辅助定位环21的环心是否与患者的瞳孔处于相对应的位置，进而对定位环2的位置进行微调，使得对患者撕囊位置的定位更加精准。In a further preferred embodiment of the utility model, the center of the auxiliary positioning ring 21 is coaxially arranged with the center of the positioning ring 2. When the positioning ring 2 is used to locate the patient's capsulorhexis position, due to certain differences in the sizes of the corneal limbus of different patients, if the deviation between the inner diameter of the positioning ring 2 and the patient's corneal limbus is too large, it will cause a certain error in the positioning of the capsulorhexis position. At this time, the center of the auxiliary positioning ring 21 can be coaxially arranged with the center of the positioning ring 2 inside the positioning ring 2 to observe whether the center of the auxiliary positioning ring 21 is in a corresponding position with the patient's pupil, and then the position of the positioning ring 2 can be fine-tuned to make the positioning of the patient's capsulorhexis position more accurate.
