摘要： A hypotraumatic injection needle having substantially no cutting edges is described. The injection needle has a beveled surface with the furthermost end of the beveled surface removed and rounded to form the needle tip. All edges on the tip and beveled portion of the needle are rounded and smoothly polished. The needle tip has a low profile, with the slope of the beveled portion being less than twenty degrees. These features allow the needle to penetrate easily by means of blunt dissection of tissue, rather than cutting tissue. The injection needle is particularly useful for posterior peribulbar or retrobulbar anesthesia in connection with ophthalmic surgery. The injection needle has a "ski-tip" effect, guiding the tip of the needle away from the beveled side. This effect, along with the absence of cutting edges, significantly reduces the hazards associated with ophthalmic surgical injections, such as inadvertent cutting of the eyeball or optic nerve. A preferred embodiment of the needle is indexed to indicate the side of the needle which is away from the beveled side.
摘要翻译： 描述了基本上没有切割边缘的假想注射针。 注射针具有倾斜表面，其中最倾斜的表面的最末端被去除并且被圆形以形成针尖。 针头的尖端和斜面部分的所有边缘均圆形且平滑抛光。 针尖具有低轮廓，斜面部分的斜面小于二十度。 这些特征使得针可以通过对组织进行钝性剥离来容易地穿透，而不是切割组织。 注射针对于与眼科手术相关的后路旁边缘或眼球后麻醉特别有用。 注射针具有“滑雪尖”效应，将针的尖端远离倾斜侧。 这种效果以及不存在切割边缘可显着降低与眼科手术注射相关的危险，例如眼球或视神经的无意切割。 针的优选实施例被转位以指示针远离倾斜侧的针的侧面。

摘要： A hand-held cannula assembly for irrigating and aspirating ophthalmic surgical sites includes an irrigation cannula circumscribed about an aspiration cannula and extending out through the forward end of the assembly from a reservoir for the irrigation fluid in the handle. Pressurized irrigation fluid is supplied to the reservoir through the rearward end of the handle and flows through openings in the irrigation cannula periphery into an annular flow passage between the two cannulas. An opening in the irrigation cannula issues the irrigation fluid at the surgical site. Aspiration fluid is drawn into the aspiration cannula which extends through the handle interior to an outflow opening at the rearward handle end.

摘要： A disposable microsurgical knife having a blade guard that can be locked into a blade covering position and then easily removed from the knife body prior to introduction to the sterile field is disclosed. The blade guard includes a cylindrical sleeve having a longitudinal slot communicating with a forward open end thereof and terminating in a circumferential notch. The knife body includes a small locking tab formed adjacent a forward tapered portion of the knife. The blade guard is initially assembled on the knife by longitudinally sliding along the knife body from a rear end thereof until the locking tab enters the longitudinal slot assisted by a funnel-shaped leading end for ease of entry. In the blade covering position, simple rotation of the sleeve forces the locking tab into the circumferential notch. For easy removal, reverse rotation of the sleeve causes the tab to re-enter the slot whereupon the sleeve is removed from the knife by sliding rearwardly along the knife body.
摘要翻译： 公开了具有刀片护罩的一次性显微外科手术刀，其可以在引入无菌区之前被锁定到刀片覆盖位置中并且随后容易地从刀体移除。 刀片护罩包括圆柱形套筒，其具有与其前开口端连通且终止于圆周凹口的纵向槽。 刀体包括邻近刀的前锥形部分形成的小锁片。 刀片防护装置最初通过沿着刀体从其后端沿着纵向滑动而组装在刀上，直到锁定突片进入由漏斗状前端辅助的纵向狭槽以便于进入。 在叶片覆盖位置，套筒的简单旋转迫使锁定片进入圆周凹口。 为了便于移除，套筒的反向旋转使得突片重新进入槽中，从而通过沿着刀体向后滑动将套筒从刀上移除。

摘要： A surgical knife includes a blade secured to the knife body and having a cutting edge projecting transversely beyond the body profile. A slotted ski member is movable axially relative to the cutting edge to selectively expose the cutting edge by means of plural thread segments which cooperate to convert rotary motion to said axially controlled axial motion. The position of the ski and blade beyond the body profile enhances visibility of the incision. In the preferred embodiment, the ski is part of a shaft which is threadedly received in a spindle, which, in turn, is threadedly received in the same sense within the knife body. The ski shaft is procluded from rotary motion relative to the knife body and its threads have a greater pitch than the body threads; consequently, axial displacement of the spindle in one direction produces axial displacement of the ski in the opposite direction. The blade and blade holder, which remain stationary relative to the body, may be disposable so that the ski and ski translating mechanism can be re-used as desired. Alternatively, the entire knife assembly may be disposable.

摘要： A hand-held cannula assembly for irrigating and aspirating opthalmic surgical sites includes as irrigation cannula circumscribed about an aspiration cannula and extending out through the forward end of the assembly from a reservoir for the irrigation fluid in the handle. Pressurized irrigation fluid is supplied to the reservoir through the rearward end of the handle and flows through openings in the irrigation cannula periphery into an annular flow passage between the two cannulas. An opening in the irrigation cannula issues the irrigation fluid at the surgical site. Aspiration fluid is drawn into the aspiration cannula which extends through the handle interior to an outflow opening at the rearward handle end. The irrigation/aspiration tip exterior is made to be smooth, protrusionless, unitary and one-piece in design to afford a minimum in tissue tearing at the surgical site, while also allowing improved irrigation fluid flow a the site.

摘要： A disposable bipolar instrument for ophthalmic surgery has a pair of shell halves carrying electrodes. A collar connects the shell halves together, and electrical conductors supply current to and from the respective electrodes. The shell halves are composed of disposable plastic material, as is the connecting collar and cap which connect the parts and hold the wires in place. Squeezing of the shell halves together is guided by a tongue-and-groove type of joint formed between the shell halves by pairs of upstanding walls, the walls having sloped surfaces in respective facing regions to permit deformation of the shell halves together at one end thereof, so as to permit movement of the electorde tips together to perform cauterization. The deformation of the plastic material causes a progressive resistance, thereby permitting a tactile feedback to the user, so that the instrument can be operated where the field of vision of the user is partially or totally obstructed.

摘要： Fluid coupling devices are disclosed for use in receptacles such as receptacles on surgical aspiration equipment for selectively connecting a fluid conduit in the receptacle with a flow passage formed through a coupling device. The coupling devices in accordance with the invention comprise a spindle member which is non-rotatably held in the receptacle and a body member rotatably mounted on the spindle member for movement between an open position in which communication is established between the flow conduit in the receptacle and the flow passage in the coupling device, and a closed position disconnecting the conduit from the flow passage. The body member has a cam insert member with a through bore for connecting the flow conduit with the flow passage. The spindle member is formed with a cam surface for urging the cam insert member outwardly when it is moved into registration with the flow conduit in the receptacle so that an annular sealing lip on the outer surface of the cam insert member is compressed around the flow conduit to form an effective seal. In one embodiment of the invention the flow passage through the coupling device is formed through the body member and in another embodiment of the invention the flow passage through the coupling device is formed axially through the spindle member.
