本发明属于医疗器械技术领域,具体涉及为一种眼内可折叠人工晶状体钳取器。The invention belongs to the technical field of medical devices, and in particular relates to an intraocular foldable artificial lens extractor.
背景技术Background Art
外伤性白内障、老年性白内障等多种原因进行的白内障超声乳化吸除+人工晶状体植入手术(phaco+IOL),外伤性或先天性晶状体脱位进行的悬吊型人工晶状体缝合术以及因屈光不正进行的有晶状体眼眼内人工晶体植入手术(ICL),此类手术均需要向患者眼内植入人工晶状体;但部分患者在某些情况下(例如:人工晶状体折叠推入眼内时即发生部分断裂破损、悬吊人工晶体脱位无法复位、人工晶状体表面增殖膜或色素及炎性沉积物严重丧失透明性影响视力、人工晶体材料引起眼内免疫性炎症无法自愈、ICL术后难治性青光眼或眼内炎症等并发症)需要将人工晶状体于患者眼内取出;在其取出过程中存在有:Cataract phacoemulsification and intraocular lens implantation (phaco+IOL) for various reasons such as traumatic cataract and senile cataract, suspended intraocular lens suturing for traumatic or congenital lens dislocation, and intraocular intraocular lens implantation (ICL) for phakic eyes due to refractive error. All of these surgeries require the implantation of intraocular lenses into the patient's eyes. However, some patients need to remove the intraocular lenses in certain circumstances (for example, the intraocular lenses are partially broken when they are folded and pushed into the eye, the suspended intraocular lenses cannot be repositioned due to dislocation, the proliferation membrane or pigment and inflammatory deposits on the surface of the intraocular lenses seriously lose transparency and affect vision, the intraocular immune inflammation caused by the intraocular lens materials cannot heal itself, and complications such as refractory glaucoma or intraocular inflammation after ICL surgery). During the removal process, there are:
①透明角膜边缘手术切口过大;巨大的角膜切口不仅不利于维持术中眼内压稳定性增加眼内容物脱出、低眼压引起的睫状体脉络膜脱离,甚至诱发恶性驱逐性脉络膜出血导致失明的风险,术后角膜大切口会造成严重的角膜变形和散光,影响预后视功能,并且人工晶状体具有一定的硬度,在拖拽出眼内时,易剐蹭角膜内皮甚至引起角膜内皮剥脱或角膜功能失代偿以及柔软虹膜组织的破损或脱色素。① The transparent corneal edge surgical incision is too large; a huge corneal incision is not only not conducive to maintaining the stability of intraocular pressure during surgery, but also increases the risk of ocular contents prolapse, ciliary choroidal detachment caused by low intraocular pressure, and even induces malignant expulsive choroidal hemorrhage leading to blindness. A large corneal incision after surgery can cause severe corneal deformation and astigmatism, affecting the prognosis and retrograde vision function. In addition, the artificial lens has a certain hardness. When being dragged out of the eye, it is easy to scratch the corneal endothelium and even cause corneal endothelial exfoliation or corneal decompensation, as well as damage or depigmentation of the soft iris tissue.
③人工晶体因体积无法完整取出时,需要使用显微剪于患者眼内对人工晶状体进行裁剪,存在显微剪的力量薄弱无法轻易剪切有一定硬度和厚度的人工晶体,以及操作空间狭小,操作过程中任何人工晶体的旋转位移以及剪刀的动作都可能伤及角膜内皮及虹膜或患者本身的晶状体(ICL患者),因而造成无法弥补的眼创伤和视功能损害。③ When the artificial lens cannot be completely removed due to its size, microscissors are needed to cut the artificial lens in the patient's eye. However, the microscissors are weak and cannot easily cut artificial lenses with a certain hardness and thickness. In addition, the operating space is small. During the operation, any rotational displacement of the artificial lens and the movement of the scissors may damage the corneal endothelium and iris or the patient's own lens (ICL patients), thereby causing irreparable eye trauma and visual function damage.
本发明针对上述问题,提供一种眼内可折叠人工晶状体钳取器。In view of the above problems, the present invention provides an intraocular foldable artificial lens extractor.

本发明的有益效果:Beneficial effects of the present invention:
1、通过设置主体件以及夹持机构,在使用时,对人工晶状体进行夹持并将人工晶状体进行折叠;使得直径/宽度范围缩小,以在取出人工晶状体时,节省了使用显微剪于患者眼内对人工晶状体进行裁剪的操作,提高了手术效率,并且从根本上避免了裁剪过程中伤及患者角膜内皮及虹膜或患者本身的晶状体的风险;1. By providing the main body and the clamping mechanism, the intraocular lens is clamped and folded during use, so that the diameter/width range is reduced, so that when the intraocular lens is removed, the operation of cutting the intraocular lens in the patient's eye with microscissors is saved, the surgical efficiency is improved, and the risk of damaging the patient's corneal endothelium and iris or the patient's own lens during the cutting process is fundamentally avoided;
2、通过约束套、夹持机构以及驱动部,实现在将人工晶状体进行夹持后,通过旋转操作被夹持折叠后的人工晶状体拖出患者角膜下,在其使用过程中,更容易使主体件保持稳定,降低夹持机构刺伤患者眼内组织的几率,同时,约束套的设置,在将人工晶状体拖拽出的过程中,使折叠后人工晶状体再次发生形变,其直径/宽度范围进一步缩小,进而避免扩大角膜边缘切口,还能够减少对患者角膜内皮剐蹭,降低造成角膜内皮剥脱或角膜功能失代偿以及柔软虹膜组织的破损或脱色素的概率。2. Through the restraining sleeve, the clamping mechanism and the driving part, after the artificial lens is clamped, the clamped and folded artificial lens can be dragged out from under the patient's cornea through a rotating operation. During its use, it is easier to keep the main body stable, reducing the chance of the clamping mechanism injuring the patient's intraocular tissue. At the same time, the setting of the restraining sleeve causes the folded artificial lens to deform again during the process of dragging the artificial lens out, and its diameter/width range is further reduced, thereby avoiding the expansion of the corneal edge incision, and can also reduce the scratches on the patient's corneal endothelium, reducing the probability of corneal endothelial exfoliation or corneal dysfunction and damage or depigmentation of the soft iris tissue.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation methods. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in 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.
图1—4示出了本实施方式的主要技术内容,本具体实施方式提供了一种眼内可折叠人工晶状体钳取器,其包括:1-4 show the main technical contents of this embodiment. This specific embodiment provides an intraocular foldable intraocular lens clamp extractor, which includes:
主体件1,具有彼此相对的伸出端13与操作端14,其中,伸出端13与操作端14相连通;The main body 1 has an extending end 13 and an operating end 14 opposite to each other, wherein the extending end 13 is connected to the operating end 14;
约束套4,与伸出端13相连接,并与伸出端13相连通;The restraining sleeve 4 is connected to the extending end 13 and communicates with the extending end 13;
夹持机构,与主体件1相连接,夹持机构具有夹持状态与张开状态,其中,夹持机构能够于夹持状态与张开状态之间转换;A clamping mechanism is connected to the main body 1, and the clamping mechanism has a clamping state and an open state, wherein the clamping mechanism can switch between the clamping state and the open state;
驱动部3,可转动的配置于主体件1的操作端14,并与夹持机构相连接,驱动部3被构造为驱使夹持机构向约束套4方向移动或者远离约束套4;其中,驱动件具有第一旋转方向与第二旋转方向,驱动部3以第一旋转方向转动时,夹持机构向约束套4方向移动,并能够部分得由约束套4伸出,在驱动部3以第二旋转方向转动时,夹持机构向远离约束套4方向移动。The driving part 3 is rotatably disposed on the operating end 14 of the main body 1 and is connected to the clamping mechanism. The driving part 3 is constructed to drive the clamping mechanism to move toward the restraint sleeve 4 or away from the restraint sleeve 4; wherein the driving member has a first rotation direction and a second rotation direction. When the driving part 3 rotates in the first rotation direction, the clamping mechanism moves toward the restraint sleeve 4 and can be partially extended from the restraint sleeve 4. When the driving part 3 rotates in the second rotation direction, the clamping mechanism moves away from the restraint sleeve 4.
在使用时,首先由术者与患者角膜做手术切口,握持主体件1将约束套4伸入该手术切口内,术者通过以第一旋转方向转动驱动部3,使得夹持机构部分的由约束套4伸入至患者角膜下,而后将夹持机构于张开状态与夹持状态之间转换,以更好的对在前植入患者眼内的人工晶状体进行夹持,此时,人工晶状体在夹持机构的夹持下,产生形变,在将人工晶状体夹持完成后,由术者以第二旋转方向转动驱动部3,使得夹持机构缩回至主体件1内,在此过程中,折叠后人工晶状体再次发生形变,其直径/宽度范围进一步缩小,进而避免扩大角膜边缘切口,并从根本上节省对人工晶状体进行裁剪的步骤,进一步的避免了对患者角膜内皮及虹膜或患者本身的晶状体造成损伤,降低了手术过程中造成患者眼创伤和视功能损害的风险。When in use, the operator first makes a surgical incision on the patient's cornea, holds the main body 1 and extends the restraining sleeve 4 into the surgical incision, and the operator rotates the driving part 3 in a first rotation direction to make the clamping mechanism part extend from the restraining sleeve 4 to under the patient's cornea, and then switches the clamping mechanism between the open state and the clamping state to better clamp the artificial lens previously implanted in the patient's eye. At this time, the artificial lens is deformed under the clamping of the clamping mechanism. After the artificial lens is clamped, the operator rotates the driving part 3 in a second rotation direction to retract the clamping mechanism into the main body 1. During this process, the folded artificial lens is deformed again, and its diameter/width range is further reduced, thereby avoiding the expansion of the corneal edge incision and fundamentally saving the step of cutting the artificial lens, further avoiding damage to the patient's corneal endothelium and iris or the patient's own lens, and reducing the risk of eye trauma and visual function damage to the patient during surgery.
更进一步地,驱动部3的第一旋转方向为顺时针旋转,第二旋转方向为逆时针旋转。Furthermore, the first rotation direction of the driving part 3 is clockwise rotation, and the second rotation direction is counterclockwise rotation.
对夹持机构进行解释,在本实施例中,参考图2—5及图8夹持机构由:移动杆2、驱动杆22以及夹持部构成,其中,移动杆2至少部分的位于主体件1内,并与驱动部3相连接,其中,移动杆2具有彼此相对的第一端与第二端,并于第一端向第二端方向开设有容纳槽211;驱动杆22与移动杆2相连接,驱动杆22的一端伸入至容纳槽211内,其中,驱动杆22能够沿移动杆2延伸方向第一端方向靠近或远离;夹持部包括彼此呈镜像设置的第一夹持臂23与第二夹持臂24,其中,第一夹持臂23与第二夹持臂24部分的配置于容纳槽211内,并均于驱动杆22相连接,其中,在驱动杆22向第一端方向移动时,第一夹持臂23与第二夹持臂24呈现为夹持状态,在驱动杆22远离第一端方向时,第一夹持臂23与第二夹持臂24呈现为张开状态,具体使用时,顺时针的转动驱动部3,此时,移动杆2向约束套4方向移动,第一夹持臂23与第二夹持臂24由约束套4伸出,此时,可根据手术需求,使第一夹持臂23与第二夹持臂24伸出至适用长度,而后推动驱动杆22向第一端方向靠近,第一夹持臂23与第二夹持臂24向夹持状态转换,进而将在前置入患者眼内的人工晶状体进行夹持,使得人工晶状体于患者眼内被折叠。The clamping mechanism is explained. In this embodiment, referring to Figures 2-5 and 8, the clamping mechanism is composed of: a moving rod 2, a driving rod 22 and a clamping portion, wherein the moving rod 2 is at least partially located in the main body 1 and connected to the driving portion 3, wherein the moving rod 2 has a first end and a second end opposite to each other, and a receiving groove 211 is opened at the first end toward the second end; the driving rod 22 is connected to the moving rod 2, and one end of the driving rod 22 extends into the receiving groove 211, wherein the driving rod 22 can approach or move away from the first end along the extension direction of the moving rod 2; the clamping portion includes a first clamping arm 23 and a second clamping arm 24 which are mirror-imaged to each other, wherein the first clamping arm 23 and the second clamping arm 24 are partially arranged in the receiving groove 211 and are both on the driving rod 22.

When in use, the driving part 3 is rotated clockwise. At this time, the moving rod 2 moves toward the restraining sleeve 4, and the first clamping arm 23 and the second clamping arm 24 are extended from the restraining sleeve 4. At this time, according to the surgical requirements, the first clamping arm 23 and the second clamping arm 24 can be extended to an applicable length, and then the driving rod 22 is pushed toward the first end, and the first clamping arm 23 and the second clamping arm 24 are converted to a clamping state, thereby clamping the artificial lens previously inserted into the patient's eye, so that the artificial lens is folded in the patient's eye.
参考图4—5及图9,作为具体地,移动杆2非圆柱形构造,优选地,移动杆2具有彼此呈镜像设置的第一弧形壁与第二弧形壁以及彼此呈镜像设置第一平面壁与第二平面壁,其中,第一平面壁的两侧分别与第一弧形壁、第二弧形壁交汇,第二平面壁与第一弧形壁、第二弧形壁之间的位置关系同第一平面壁,最为优选地,第一弧形壁与第二弧形壁同圆心;主体件1具有腔道11,腔道11的横截面与移动杆2的横截面形状相同,通过此时设置,在驱动部3转动时,通过该腔道11对移动杆2形成限位作用,使得移动杆2仅沿该腔道11延伸方向做轴向的移动,进而避免随驱动部3同步的转动;以此使得第一夹持臂23与第二夹持臂24能够伸出至目标位置。4-5 and 9, as a specific example, the moving rod 2 has a non-cylindrical structure. Preferably, the moving rod 2 has a first arcuate wall and a second arcuate wall that are mirror images of each other, and a first plane wall and a second plane wall that are mirror images of each other, wherein the two sides of the first plane wall intersect with the first arcuate wall and the second arcuate wall respectively, and the positional relationship between the second plane wall and the first arcuate wall and the second arcuate wall is the same as the first plane wall. Most preferably, the first arcuate wall and the second arcuate wall are concentric; the main body 1 has a cavity 11, and the cross-section of the cavity 11 is the same as the cross-sectional shape of the moving rod 2. By setting it at this time, when the driving part 3 rotates, the cavity 11 forms a limiting effect on the moving rod 2, so that the moving rod 2 only moves axially along the extension direction of the cavity 11, thereby avoiding synchronous rotation with the driving part 3; thereby, the first clamping arm 23 and the second clamping arm 24 can be extended to the target position.
参考图4—5及图8—9,作为具体地,驱动杆22可采用本实施例中的方式与移动杆2相配合,于移动杆2的第二端向容纳槽211方向设置孔道,其中,孔道与容纳槽211相连通,驱动杆22配置于孔道内,优选地,孔道与容纳槽211相连通的一端设置有带有通孔的隔板,孔道通过通孔与容纳槽211相通,驱动杆22由通孔伸入至容纳槽211内,更为优选地,该孔道与腔道11之间同圆心,使得主体件1、移动杆2、驱动部3、以及驱动杆22之间为同圆心关系,进而最大程度的缩小主体件1的最大直径,以使的术者更易握持。Referring to Figures 4-5 and Figures 8-9, as a specific example, the driving rod 22 can cooperate with the moving rod 2 in the manner of the present embodiment, and a channel is set at the second end of the moving rod 2 in the direction of the accommodating groove 211, wherein the channel is connected with the accommodating groove 211, and the driving rod 22 is arranged in the channel. Preferably, a partition with a through hole is set at one end of the channel connected with the accommodating groove 211, and the channel is connected with the accommodating groove 211 through the through hole, and the driving rod 22 extends into the accommodating groove 211 through the through hole. More preferably, the channel is concentric with the cavity 11, so that the main body 1, the moving rod 2, the driving part 3, and the driving rod 22 are in a concentric relationship, thereby minimizing the maximum diameter of the main body 1 to the greatest extent, so that the operator can hold it more easily.
参考图4—7,在本实施例中,驱动杆22被构造为始终远离第一端,进而使得夹持部始终为张开状态,具体地,驱动杆22具有连接段,其中,绕连接段设置弹簧214,弹簧214的一端抵靠于隔板,弹簧214的另一端抵靠于驱动杆22的其他部位,以此使得驱动杆22始终远离第一端,在驱动杆22的向第一端靠近时,弹簧214受力被压缩,具体使用时,通过驱动部3使移动杆2向约束套4方向靠近,此时,第一夹持臂23的前端、第二夹持臂24的前端与约束套4的内壁向抵接,并在该抵接关系下,第一夹持臂23的前端与第二夹持臂24的前端相靠近,进而避免第一夹持臂23与第二夹持臂24以过度张开的状态进入患者的眼内;进而避免对患者角膜开口造成扩张。4-7, in the present embodiment, the driving rod 22 is constructed to always be away from the first end, so that the clamping portion is always in an open state. Specifically, the driving rod 22 has a connecting section, wherein a spring 214 is arranged around the connecting section, one end of the spring 214 abuts against the partition, and the other end of the spring 214 abuts against other parts of the driving rod 22, so that the driving rod 22 is always away from the first end. When the driving rod 22 approaches the first end, the spring 214 is compressed by force. When in use, the moving rod 2 is moved toward the restraining sleeve 4 through the driving portion 3. At this time, the front end of the first clamping arm 23 and the front end of the second clamping arm 24 abut against the inner wall of the restraining sleeve 4, and under this abutting relationship, the front end of the first clamping arm 23 is close to the front end of the second clamping arm 24, thereby preventing the first clamping arm 23 and the second clamping arm 24 from entering the patient's eye in an over-open state; thereby avoiding expansion of the patient's corneal opening.
参考图6—8,在本实施例中,第一夹持臂23枢转的连接于容纳槽211的槽壁,其中,第一夹持臂23具有连接端与夹持端,在驱动杆22向第一端方向靠近时,第一夹持臂23的夹持端与第二夹持臂24的夹持端相靠近;优选地,第一夹持臂23具有第一防滑面,第二夹持臂24具有第二防滑面,其中,在夹持状态下,第一防滑面与第二防滑面相贴合;在使用时,通过第一防滑面与第二防滑面使得在将人工晶状体进行夹持时,增强与人工晶状体之间的摩擦力,使得人工晶状体不易于第一夹持臂23与第二夹持臂24之间滑脱,进而将人工晶状体夹持折叠以及夹持牢固。Referring to Figures 6-8, in this embodiment, the first clamping arm 23 is pivotally connected to the groove wall of the accommodating groove 211, wherein the first clamping arm 23 has a connecting end and a clamping end, and when the driving rod 22 approaches the first end, the clamping end of the first clamping arm 23 is close to the clamping end of the second clamping arm 24; preferably, the first clamping arm 23 has a first anti-slip surface, and the second clamping arm 24 has a second anti-slip surface, wherein in the clamping state, the first anti-slip surface is in contact with the second anti-slip surface; when in use, the first anti-slip surface and the second anti-slip surface are used to enhance the friction between the artificial lens and the artificial lens when clamping the artificial lens, so that the artificial lens is not easy to slip between the first clamping arm 23 and the second clamping arm 24, thereby clamping the artificial lens, folding it and clamping it firmly.
参考图1及图5—7,在本实施例中,对驱动杆22与第一夹持臂23、第二夹持臂24之间的连接关系进行解释;其中,驱动杆22具有驱动端,驱动端具有第一倾斜滑槽222与第二倾斜滑槽223;第一夹持臂23的连接端滑动的配置于第一倾斜滑槽222内,第二夹持臂24的连接端滑动的配置于第二倾斜滑槽223内,在驱动端向第一端方向移动时,第一夹持臂23的连接端与第二夹持臂24的连接端相远离,在驱动端远离第一端方向移动时,第一夹持臂23的连接端与第二夹持臂24的连接端相靠近;具体地,驱动端整体呈现为等腰梯形状,此时,驱动端具有两条倾斜边,第一倾斜滑槽222与第二倾斜滑槽223分别单独开设于两条倾斜边上,第一夹持臂23的连接端滑动的配置于第一倾斜滑槽222,且不会于第一倾斜滑槽222脱出,同样的,第二夹持臂24的连接端不会于第一倾斜滑槽222脱出;再次设置下,通过按压驱动杆22的方式,实现第一夹持臂23与第二夹持臂24转换为夹持状态,以此在术者进行操作时,更加方便的对驱动杆22进行施力,以在对人工晶状体的夹持过程中,避免主体件1出现晃动,以此进一步地降低造成患者眼创伤和视功能损害的风险。With reference to FIGS. 1 and 5-7 , in the present embodiment, the connection relationship between the driving rod 22 and the first clamping arm 23 and the second clamping arm 24 is explained; wherein the driving rod 22 has a driving end, and the driving end has a first inclined slot 222 and a second inclined slot 223; the connecting end of the first clamping arm 23 is slidably arranged in the first inclined slot 222, and the connecting end of the second clamping arm 24 is slidably arranged in the second inclined slot 223, when the driving end moves toward the first end, the connecting end of the first clamping arm 23 is away from the connecting end of the second clamping arm 24, and when the driving end moves away from the first end, the connecting end of the first clamping arm 23 is close to the connecting end of the second clamping arm 24; specifically, the driving end as a whole presents an isosceles ladder shape, at this time, the driving end has two inclined edges, the first inclined slot 222 and the second inclined slot 223 are separately opened on the two inclined edges, the connecting end of the first clamping arm 23 is slidably configured in the first inclined slot 222, and will not fall out of the first inclined slot 222, similarly, the connecting end of the second clamping arm 24 will not fall out of the first inclined slot 222; under the setting again, by pressing the driving rod 22, the first clamping arm 23 and the second clamping arm 24 are converted into a clamping state, so that when the operator is operating, it is more convenient to apply force to the driving rod 22, so as to avoid shaking of the main body 1 during the clamping process of the artificial lens, thereby further reducing the risk of causing eye trauma and visual function damage to patients.
作为优选地,驱动端的宽度大于孔道的直径,在驱动杆22未受力,弹簧214处于展开的状态下,驱动端不会由通孔进入至孔道内,进而避免驱动杆22于移动杆2内脱出。Preferably, the width of the driving end is greater than the diameter of the hole. When the driving rod 22 is not stressed and the spring 214 is in an expanded state, the driving end will not enter the hole through the through hole, thereby preventing the driving rod 22 from falling out of the moving rod 2.
作为优选地,驱动端的厚度大于容纳槽211的宽度,以使的驱动端被限制在容纳槽211之间,但在孔道的限制下,仅于容纳槽211内做直线运动,并且使得驱动杆22不能够发生转动,进而进一步的保证器械在使用时具有良好的稳定性。Preferably, the thickness of the driving end is greater than the width of the accommodating groove 211, so that the driving end is confined between the accommodating grooves 211, but under the limitation of the channel, it only makes linear motion in the accommodating groove 211, and the driving rod 22 cannot rotate, thereby further ensuring that the device has good stability when in use.
作为可替换地(未图示),驱动杆22进入至容纳槽211的一端铰接有第一连杆与第二连杆,其中,第一连杆连接至第一夹持臂23的连接端,第二连杆连接至第二夹持臂24的连接端,第一连杆位于第二连杆厚度方向上的上方,且第一连杆与第二连杆之间具有夹角并呈现为“V”型;在按压驱动杆22时,第一连杆与第二连杆之间的夹角的度数增大,此时第一夹持臂23与第二夹持臂24向夹持状态转换,当驱动杆22在弹簧214的作用下向远离第一端方向移动,第一连杆与第二连杆之间的夹角的度数缩减,此时第一夹持臂23与第二夹持臂24向张开状态转换。As an alternative (not shown), the end of the driving rod 22 that enters the accommodating groove 211 is hinged with a first connecting rod and a second connecting rod, wherein the first connecting rod is connected to the connecting end of the first clamping arm 23, and the second connecting rod is connected to the connecting end of the second clamping arm 24, the first connecting rod is located above the second connecting rod in the thickness direction, and there is an angle between the first connecting rod and the second connecting rod and presents a "V" shape; when the driving rod 22 is pressed, the degree of the angle between the first connecting rod and the second connecting rod increases, and at this time the first clamping arm 23 and the second clamping arm 24 are converted to a clamping state, and when the driving rod 22 moves away from the first end under the action of the spring 214, the degree of the angle between the first connecting rod and the second connecting rod is reduced, and at this time the first clamping arm 23 and the second clamping arm 24 are converted to an open state.
参考图6—7及图10—11,在本实施例中,第一夹持臂23与第二夹持臂24还被构造为能够始终保持夹持状态,具体地,夹持机构还包括有:配置于移动杆2内的止动件25,于驱动杆22的外侧壁设置卡槽26,其中,驱动端与第一端之间具有第一移动范围与第二移动范围,在驱动端于第一移动范围内向第一端移动时,止动件25允许驱动端向第一端靠近或远离第一端;在驱动端位于第二移动范围时,止动件25进入至卡槽26内,使得驱动端距与第一端之间的距离被固定,进而使得第一夹持臂23与第二夹持臂24始终保持夹持状态。6-7 and 10-11, in the present embodiment, the first clamping arm 23 and the second clamping arm 24 are also constructed to be able to always maintain a clamping state. Specifically, the clamping mechanism also includes: a stopper 25 arranged in the movable rod 2, and a slot 26 is provided on the outer wall of the driving rod 22, wherein a first moving range and a second moving range are provided between the driving end and the first end, and when the driving end moves toward the first end within the first moving range, the stopper 25 allows the driving end to approach or move away from the first end; when the driving end is located in the second moving range, the stopper 25 enters into the slot 26, so that the distance between the driving end and the first end is fixed, thereby allowing the first clamping arm 23 and the second clamping arm 24 to always maintain a clamping state.
具体地,驱动杆22的外壁还具有第一标识与第二标识,第一标识与第二标识之间的距离与第一移动范围向对应;其中,在原始状态下/驱动杆22未移动时,第一标识与移动杆2第二端的边缘相重合,在对驱动杆22施力时,第一标识进入至移动杆2内,移动杆2第二端的边缘位于第一标识与第二标识之间,此时,第一夹持臂23与第二夹持臂24能够反复的开合;在第二标识与移动杆2第二端的边缘相重合,此时,止动件25进入至卡槽26内,使得驱动端距与第一端之间的距离被固定,进而使得第一夹持臂23与第二夹持臂24始终保持夹持状态;在使用时,术者根据第一标识、第二标识与移动杆2第二端边缘之间的位置关系,控制第一夹持臂23与第二夹持臂24对人工晶状体进行夹持,在确定人工晶状体被夹持至理想状态后,可将驱动杆22下压至第二标识与移动杆2第二端边缘重合,此时,止动件25进入至卡槽26内,同时,第一夹持臂23与第二夹持臂24保持夹持状态,使得驱动杆22的位于相对与移动杆2不变,而后逆时针的转动驱动部3,使第一夹持臂23与第二夹持臂24向主体件1的操作端14方向移动,此时,人工晶状体被向约束套4方向拖动,并逐渐的抵靠约束套4,以此进一步的产生形变,进入至约束套4内,以此避免在人工晶状体取出的过程中扩大患者角膜边缘切口,避免造成术后患者出现严重的角膜变形和散光,同时,将人工晶状体取出的过程中,还能够减少对患者角膜内皮剐蹭,降低造成角膜内皮剥脱或角膜功能失代偿以及柔软虹膜组织的破损或脱色素的概率。Specifically, the outer wall of the driving rod 22 also has a first mark and a second mark, and the distance between the first mark and the second mark corresponds to the first moving range; wherein, in the original state/when the driving rod 22 has not moved, the first mark coincides with the edge of the second end of the moving rod 2, and when force is applied to the driving rod 22, the first mark enters into the moving rod 2, and the edge of the second end of the moving rod 2 is located between the first mark and the second mark. At this time, the first clamping arm 23 and the second clamping arm 24 can be repeatedly opened and closed; when the second mark coincides with the edge of the second end of the moving rod 2, at this time, the stopper 25 enters into the card slot 26, so that the distance between the driving end and the first end is fixed, thereby making the first clamping arm 23 and the second clamping arm 24 always maintain a clamping state; when in use, the operator controls the first clamping arm 23 and the second clamping arm 24 to clamp the artificial lens according to the positional relationship between the first mark, the second mark and the edge of the second end of the moving rod 2, and determines After the artificial lens is clamped to an ideal state, the driving rod 22 can be pressed down until the second mark coincides with the second end edge of the moving rod 2. At this time, the stopper 25 enters the slot 26. At the same time, the first clamping arm 23 and the second clamping arm 24 maintain a clamping state, so that the position of the driving rod 22 relative to the moving rod 2 remains unchanged, and then the driving part 3 is rotated counterclockwise to move the first clamping arm 23 and the second clamping arm 24 toward the operating end 14 of the main body 1. At this time, the artificial lens is dragged toward the restraining sleeve 4 and gradually abuts against the restraining sleeve 4, thereby further deforming and entering the restraining sleeve 4, thereby avoiding enlarging the patient's corneal edge incision during the removal of the artificial lens, avoiding severe corneal deformation and astigmatism in the patient after surgery, and at the same time, in the process of removing the artificial lens, it can also reduce the scratching of the patient's corneal endothelium, reduce the probability of corneal endothelial exfoliation or corneal dysfunction and damage or depigmentation of the soft iris tissue.
参考图5—6及图11,具体地,止动件25为弹性片,具有第一倾斜壁,驱动杆22的外侧壁具有第二倾斜壁,在驱动杆22移动时,第二倾斜壁作用于第一倾斜壁上,使得止动件25产生形变,以此使得第一夹持臂23与第二夹持臂24能够在驱动件于第一移动范围内移动时反复的开合,在卡槽26与止动件25相对应后,止动件25依靠自身弹性卡入卡槽26内,以此使得驱动杆22的位置被固定。Referring to Figures 5-6 and 11, specifically, the stop member 25 is an elastic sheet having a first inclined wall, and the outer wall of the driving rod 22 has a second inclined wall. When the driving rod 22 moves, the second inclined wall acts on the first inclined wall, causing the stop member 25 to deform, so that the first clamping arm 23 and the second clamping arm 24 can repeatedly open and close when the driving member moves within the first moving range. After the slot 26 corresponds to the stop member 25, the stop member 25 relies on its own elasticity to be inserted into the slot 26, so that the position of the driving rod 22 is fixed.

When the driving sleeve rotates, the moving rod 2 is restricted by the cavity 11 and cannot rotate synchronously with the driving sleeve. Therefore, under the drive of the driving sleeve, the moving rod 2 approaches or moves away from the constraint sleeve 4 along the cavity 11. When in use, the first clamping arm 23 and the second clamping arm 24 are gradually extended from the constraint sleeve 4 by rotating the driving sleeve clockwise, and the first clamping arm 23 and the second clamping arm 24 are gradually retracted into the driving sleeve by rotating the driving sleeve counterclockwise.

For example, the restraint sleeve 4 is plugged into the protruding end 13, wherein the protruding end 13 has an extension section, and the restraint sleeve 4 and the extension section are interference fit; thereby, the restraint sleeve 4 and the extension section form a connection relationship.
优选地,约束套4采用硬质塑料制成,以此在拖拽人工晶状体时,人工晶状体能够在抵靠于约束套4后产生变形,进而将夹取后的人工晶状体拖入约束套4内。Preferably, the restraining sleeve 4 is made of hard plastic, so that when the artificial lens is dragged, the artificial lens can be deformed after abutting against the restraining sleeve 4 , thereby dragging the clamped artificial lens into the restraining sleeve 4 .
