Description

电动手术刀 Electric scalpel

所属技术领域 Those of skill

[0001 ] 本发明涉及一种外科手术器械,具体地说是一种电动手术刀。 [0001] The present invention relates to a surgical instrument, in particular an electric scalpel.

背景技术 Background technique

[0002]目前,外科手术使用的手术刀一直是将手术刀片安装在薄片状的刀柄上,有一定经验的高年资外科医生都有这样的感觉:这种薄片状的刀柄要用手指捏住,较长时间捏持后会感到手指疲劳酸软,这种感觉在进行较大面积的解剖分离手术操作时尤其明显;另外, 在切开组织时的精准度方面也存在不足,尤其是想要切出一个圆滑的小圆弧状皮肤切口时更是十分困难,总是切得不够圆滑,切口边缘参差不齐,这种感觉在美容外科手术时更是经常遇到。 [0002] Currently, the use of a scalpel surgery has been the scalpel blade mounted on the handle flaky, have some experience of high qualification surgeons have this feeling: This flaky handle with your fingers pinch, pinch after a long time will feel tired fingers and knees, feeling conducting a larger area of ​​the anatomical separation is particularly evident surgical operation; in addition, in terms of accuracy when cutting tissue also shortcomings, especially want to cut out a small round smooth arc when the skin is very difficult to cut, cut enough always smooth, cut jagged edges, this feeling is more frequently encountered in the cosmetic surgery.

[0003] 原因分析:要想准确地切开皮肤或其他组织,手术者需要集中精力地同时做好以下三个动作:1、对刀片施加一定的压力(朝向被切割的组织);2、让刀刃在被切割组织的表面移动;3、随时调整好刀片的前进方向。 [0003] Analysis: To accurately cut the skin or other tissue, the surgeon needs to focus simultaneously do the following three actions: 1, put some pressure on (toward the cutting of tissue) of the blade; 2, let moving the blade surface being cut tissue; 3, always adjust the traveling direction of the blade is good. 很显然,这三个动作相互影响,如果刀刃能够自行地在被切割组织的表面小幅度地快速往复移动,那么手术者只需对刀片施加很轻巧的压力即可轻松地切开组织,而且还会因此而可以将更多的注意力和手指力量移注于调整和掌握刀刃的前进方向,达到随心所欲、轻松准确地切开皮肤或其他坚韧的组织。 Obviously, these three actions affect each other, if the blade quick to reciprocate the cut surface of the tissue itself in small increments, so the operator simply applying very light pressure on the blade can easily cut tissue, but also It will therefore be more attention and finger strength transferring to adjust and grasp the forward direction of the blade to achieve arbitrary, easily and accurately cut the skin or other tissue tough.

发明内容 SUMMARY

[0004] 本发明的主要目的之一是解决目前的手术刀使用过程中有时不能准确地、随心所欲地进行切割的问题,另外一个目的是为了解决目前的手术刀柄长时间捏持使用时手指容易感到疲劳酸痛的问题。 [0004] One of the main purposes of the present invention is to solve the current surgical procedure sometimes not accurately, free to use cutting issues, another purpose is to solve the current surgical knife handle for a long time when the grip is easy to use finger the problem was tired and sore.

[0005] 为了达到以上两个目的,本发明将刀柄设计成适合于手指捏持的细长圆柱状(圆珠笔状),持用时更加舒适、稳妥,并且在刀柄内部安装了电磁动力驱动系统,该驱动系统采用三组微型交流电磁铁-衔铁组联合驱动,能够保证产生足够的驱动力量,交流电的快速交变特性,保证了刀片往复运动的高频快速。 [0005] To achieve the above two objects, the present invention is designed to be suitable for the holder finger grip elongated cylindrical shape (like a ballpoint pen), with a more comfortable hold, secure, and electromagnetic driving system mounted inside the shank, the drive system uses three sets of miniature AC solenoids - group united drive armature, to ensure a sufficient driving force is generated, rapid alternating AC characteristics to ensure rapid high frequency reciprocating blade. 因此,手术者只需对刀片施加轻巧的压力即可轻松地切开组织,而且还可以因此而将更多的注意力和手指力量移注于调整和掌握刀刃的前进方向,达到随心所欲、轻松准确地切开皮肤或其他组织。 Therefore, the operator simply applying pressure on the lightweight blades can be easily cut tissue, and can therefore also be more attention and finger strength transferring to adjust and grasp the forward direction of the blade to achieve arbitrary, easily and accurately to cut the skin or other tissue.

[0006] 本发明的有益效果是,可以帮助手术者轻巧、准确地切开皮肤或其他坚韧的组织, 尤其是在进行较大面积的切开或锐性分离操作时,能够有助于提高手术的效率和质量,在进行美容手术时更是较普通手术刀具有明显的精巧优势。 [0006] Advantageous effects of the present invention is that light can help the operator to accurately cut the tough skin or other tissues, especially during large area of ​​the cut or sharp separation operation, the operation can contribute to improvement efficiency and quality, but also during cosmetic surgery has obvious advantages over ordinary delicate scalpel. 以下结合附图和实施例对本发明作进一步说明。 The present invention will be further described in conjunction with the accompanying drawings and embodiments.

具体实施方式 detailed description

[0010] 如图I所示,本发明由刀片⑷和电动刀柄⑶两部分组成,刀片⑷通过卡口(I)连接于传动轴(2)上。 [0010] FIG I, the present invention by the blade shank and the motor ⑷ ⑶ two components, by a bayonet blade ⑷ (I) is connected to the transmission shaft (2). 电动刀柄(B)外观似圆珠笔状,其外壳(14)为塑胶材质,前部设有按钮开关(16),尾端连接24V. 50HZ的交流电源线(15),在其前端和后端分别镶设有耐磨金属材质的、横断面有方形洞道的前滑道(3)和后滑道(12)。 Electric tool holder (B) like a ball-point pen-like appearance, which housing (14) of plastic material, provided with a front push-button switch (16), connected to the trailing end of 24V. 50HZ AC power line (15), at its front and rear ends each insert is provided with wear-resistant metal material, channel cross-section with square holes of the front guide rail (3) and a rear slide (12). 传动轴(2)为耐磨的非磁性金属材质的细长立方体,其前段和后段能够分别在前滑道(3)和后滑道(12)内直线往复滑动而不能旋转,传动轴(2)的前部设有非磁性金属材质的挡块(5),在前滑道(3)与挡块 The propeller shaft (2) is an elongated cube wear-resistant non-magnetic metal material, its front and rear sections are not capable of rotating the front chute (3) and a rear slide (12) linearly reciprocally slidable shaft ( 2) a front portion provided with a stopper nonmagnetic metal material (5), the front guide rail (3) and the stopper

(5)之间有一前弹簧(4)套于传动轴(2)上,传动轴(2)的后端与安放于后滑道(12)内的后弹簧(13)相顶触。 A front spring (4) sets the drive shaft (2) between (5), the rear end of the propeller shaft (2) and the rear spring mounted on the slide (12) inside (13) with a top contact. 电磁铁a(6)、电磁铁b (8)、电磁铁c (10)都为相同的圆柱状,其外周都固定在外壳(14)的内壁上,相互间隔地同轴、同向排列,其铁芯的轴心部位都有足够宽松的方形洞道可供传动轴(2)穿过,该三个电磁铁并联于24伏的交流电路中,同时接受按钮开关(16)的控制。 Solenoid a (6), the electromagnet b (8), the electromagnet c (10) are the same cylindrical outer circumferential wall of the housing are mounted on (14) coaxially spaced apart from each other, arranged in the same direction, axial core portion which has a sufficiently loose hole of square channel for the transmission shaft (2) passes through the three electromagnets connected in parallel to the circuit 24 volts AC, while the accept button switch (16) is controlled. 衔铁a(7)、衔铁b(9)、衔铁C(Il)为软磁材料,都呈圆柱状,轴心部位都有方形洞孔可以牢固套定在传动轴(2)上。 Armature a (7), the armature b (9), the armature C (Il) is a soft magnetic material, are cylindrical, axial portion has a square hole in the drive shaft can be firmly fixed on the sleeve (2). 三个电磁铁都没有电流通过时,前弹簧(4)和后弹簧(13)都处于自然长度状态,衔铁a (7)与临近的电磁铁a(6)之间、衔铁b(9)与临近的电磁铁b⑶之间、衔铁c (11)与临近的电磁铁c (10)之间都保持有约2mm的气隙,而衔铁a(7)与电磁铁b(8)之间、衔铁b(9)与电磁铁c(lO)之间的间距都在12mm以上,这样通电时电磁铁b(8)对衔铁a (7)、电磁铁c (10)对衔铁b(9)的吸力就会很弱,从而保证衔铁a (7)只被电磁铁a (6)吸动,衔铁b (9)只被电磁铁b (8)吸动。 When no current through the three electromagnets, the front spring (4) and the rear springs (13) are in the natural length state, the armature between a (7) and the adjacent electromagnet a (6), the armature b (9) and between adjacent electromagnet b⑶, c armature (. 11) and the adjacent electromagnet is maintained between c (10) an air gap of about 2mm, and the armature a (7) between the electromagnet b (8), the armature spacing between b (9) and electromagnet c (lO) are more than 12mm, when the electromagnet is energized so that b (8) of the armature a (7), the electromagnet c (10) of the suction armature b (9) of will be very weak, so as to ensure the armature a (7) is only the electromagnet a (6) puff actuated, armature b (9) only by an electromagnet b (8) puff actuated.

[0011] 使用时,按下按钮开关(16)接通24伏特的交流电后,在交流电处于正半周时,电磁铁a(6)、电磁铁b (8)、电磁铁c (10)同时产生磁性,分别将各自临近的衔铁a(7)、衔铁b(9)、衔铁C(Il)同时吸引牵拉,共同带动传动轴(2)向前滑动,前弹簧(4)被压缩而储能;在交流电处于零点附近时,电磁铁对衔铁的吸力急剧减小,被压缩性了的前弹簧(4)则反弹将传动轴(2)向后推移滑动,后弹簧(13)被压缩而储能,在交流电进入负半周时,电磁铁a (6)、电磁铁b⑶、电磁铁c (10)再次同时产生磁性,再次分别地将各自临近的衔铁a (7)、衔铁b (9)、衔铁c (11)同时向前吸引牵拉,再加上后弹簧(13)的反弹力量,共同带动传动轴(2)再次向前滑动,如此随着交流电流的交替变化,传动轴(2)将快速地、小振幅地往复移动,从而带动与之相连的刀片(A)快速地、小振幅地往复移动, After [0011] In use, pushes the button switch (16) turned 24 volts AC, alternating current is in the positive half cycle, the electromagnet a (6), the electromagnet b (8), the electromagnet c (10) simultaneously generates magnetic, respectively, adjacent respective armature a (7), the armature b (9), the armature C (Il) attract drawing, common drive shaft (2) slide forward, the front spring (4) is compressed to a storage ; when AC power is in the vicinity of zero, suction solenoid armature is drastically reduced, the compressed spring of the front (4) the rebound transmission shaft (2) goes back slide, the spring (13) is compressed to a reservoir can, when entering the negative half cycle of the alternating current, the electromagnet a (6), an electromagnet b⑶, the electromagnet c (10) while generating a magnetic again, again respectively near the respective armature of a (7), the armature b (9), armature c (11) while pulling forward to attract, plus the spring (13) rally forces to drive the propeller shaft (2) slides forward again, such as the alternating AC current, drive shaft (2) the rapid, reciprocating movement of small amplitude, so as to drive the blade (a) connected thereto rapid, small amplitude reciprocated, 实现对皮肤或其他坚韧组织的轻松切开或锐性分离。 For easy cutting or sharp separation of tough skin or other tissue. 前弹簧(4)和后弹簧(13)的主要作用是在非通电状态下保证三块衔铁与各自相邻的电磁铁之间保持一定的距离(2mm左右),并且在通电运行的过程中通过被压缩储能和反弹复原释能而缓冲运动,减轻震荡,使用起来更加平稳和舒适。 The main role of the front springs (4) and a rear spring (13) is to ensure a certain distance between the armature and the respective adjacent three electromagnets (2mm or so) in the non-energized state, and by running during energization compressed energy storage and release energy recovery and the rebound cushion movement, reduce shock, use more smooth and comfortable.

[0012] 本发明通电使用时,其刀片(A)会呈现为刀影,该刀影要比刀片的实际大小稍长,手术者只需将该刀影当成刀片看待和使用,就可以确保安全地切割组织,不会误切误伤附近的其他组织。 [0012] When the present invention is the use of electricity, which blade (A) will appear as a shadow knife, the knife shadow longer than the actual size of the blade, the operator just as the knife blade Movies evaluate and use, the safety can be ensured cutting tissue, will not mistakenly cut other tissue near the fire. 另一方面,由于刀片往复快速运动,手术者只需要对刀片施加很小的压力即可切开组织,因而在制造手术刀片时就可以将刀片制作得非常小巧(美容手术专用微型刀片),不再需要像普通手术刀片那样必须具有相当的宽度和强度才不至于被压断和折断,因而在施行美容手术时更有优势。 On the other hand, due to the rapid motion of the reciprocating blade, the operator need only apply a small pressure to the blade to cut the tissue, and thus the sheet for manufacturing a surgical blade can be made very compact (dedicated microblades cosmetic surgery), not then that must have required considerable width and intensity they are not like ordinary scalpel blade was crushed and broken, and therefore have an advantage in the implementation of cosmetic surgery. [0013] 从以上所述可以看出,本发明结构简单,通过使用三组微型交流电磁铁-衔铁组联合驱动,保证了即使将电动刀柄做成适合于手指捏持的细长圆管状(圆珠笔状),也能够保证产生足够的驱动力量,交流电的快速交变特性,保证了刀片往复运动的高频快速。 [0013] As can be seen from the above, the simple structure of the present invention, by using three sets of mini AC solenoids - group united drive armature, to ensure that the holder is made even when the motor is adapted to the elongated finger grip of round tubular (like a ballpoint pen ), it is possible to guarantee a sufficient driving force, rapid alternating AC characteristics to ensure rapid high frequency reciprocating blade. 使用该电动手术刀,可以帮助手术者快速、轻巧、准确的切割或锐性分离坚韧的组织,明显提高手术的效率和质量,在进行美容手术时更是较普通手术刀具有明显的精巧优势。 Use the electric scalpel, surgery can help fast, lightweight, accurate cutting or sharp separation of tough tissue, significantly improve the efficiency and quality of the surgery, but also has obvious advantages over ordinary delicate scalpel during cosmetic surgery.
