摘要:
The device comprises a generally cylindrically shaped body having an elongated base with a distal end and a proximal end, and is conformed to be received by a fingertip of a medical practitioner. A plurality of prongs for debridement scrapping are formed on an outer surface of the base. A pair of arcuately shaped portions are integrally formed with the base to secure the device to any finger of a medical practitioner.

Es wird ein Hautschaber in Form einer Klinge beschrieben, der dadurch gekennzeichnet wird, dass die Klinge zwei lange Seiten a und b und zwei schmalere Seiten c und d aufweist und wobei die Seiten a und b eine gleiche Form aufweisen.
摘要:
Tools, devices and systems that include a generally cylindrical, hollow shaft, and a suction canister are provided with advantageous interconnectivity features and functions that enable ease of manufacturing, lowered manufacturing costs, and allow for a platform of different shaft embodiments and canister embodiments that may be manufactured in different combinations to form an array of unique instruments. The interconnectivity may be irreversible or reversible, and the connection features maintain an air tight seal between the components. Tools, devices and systems are also provided that include collection functionality that can be employed to manipulate the volume of tissue collected while using a tissue collection feature/function. This may be undertaken to restrict total volume of the collection chamber in a way that allows for continuous suction flow rate to take place while collecting the desired amount of tissue. Containing the tissue to a pre-set volume can enable a user to effectively ascertain the volume of tissue collected.
摘要:
A medical device in the form of a tool (11) for removing necrotic tissue from a wound or for cutting or both. The tool (11) includes an elongated handle (13) and a tool head (15). The handle (13) has a distal end (13a), a proximal end (13b) and defines a central longitudinal axis (13c) extending between the ends. The tool head (15) is of substantially elliptical form having a major axis (15a) and is connected to the proximal end (13b) of the handle so that the major axis (15a) of the tool head is offset relative to the longitudinal axis (13c) of the handle. The tool head (15) has a convex face (17a) on one side, a concave face (17b) that is disposed complementary to the convex face on the other side of the tool and a serrated edge (19) disposed at the end of the tool head, distal from the proximal end (13b) of the handle (11). The serrated edge (19) extends transversely of the longitudinal axis (13c) of the handle, and the tool head (15) defines bifurcated peripheral edges (21a and 21b) extends convexly from either end of the serrated edge (19) to the proximal end of the handle. In one embodiment, the serrated edge (19) and peripheral edges (21) of the tool head (15) are sufficiently pointed to facilitate loosening and scraping of eschars and removal of necrotic tissue from a wound but sufficiently blunt to substantially prevent cutting of surrounding healthy tissue. In another embodiment the operating edge of the peripheral edges and the serrated edge of the tool head are sufficiently pointed to provide cutting of tissue.

본 발명은 수술용 체내 조직 제거장치에 관한 것이다. 이는, 케이싱과; 제어신호를 발생하는 제어부와; 상기 케이싱의 내부에 장착되며 상기 제어부의 제어신호를 받아 진동을 출력하는 진동발생부와; 상기 진동발생부에 링크된 상태로 케이싱의 외부로 연장되고, 연장단부가 체내의 목표지점에 도달하도록 체내에 삽입되는 것으로서, 상기 진동발생부의 작동에 연동하여 길이방향으로 진동하는 진동로드와; 상기 진동로드의 연장단부에 밀착 고정되며 제거할 대상에 접한 상태로 진동하여, 접하고 있는 제거대상을 긁어 제거하는 스크레이퍼와; 상기 스크레이퍼를 원하는 곡률로 벤딩시켜 제거대상에 밀착시키는 벤딩수단을 포함하는 것을 특징으로 한다. 상기와 같이 이루어지는 본 발명의 수술용 체내 조직 제거장치는, 능동적 조향수단을 가지므로 추간공 내부로의 진입이 원활함은 물론 추간공 내부의 정확한 위치에 세팅이 가능하고, 또한 제거대상을 갈아내기 위한 스크레이핑플레이트가 플렉시블하여 추간공 내부에서 환부에 완전히 밀착한 상태로 동작하므로 그만큼 제거효율이 뛰어나며. 또한 모터를 이용해 스크레이핑플레이트를 진동시키는 방식이므로 매우 빠른 시간에 조직 제거를 완료할 수 있게 한다.
摘要:
A tool for removing debris from sockets containing screws of electrical conductors of medical pacemakers, to allow engagement of screw heads for unthreading. The tool includes a body, with a screw driving blade projecting from one end and a cutting blade of diameter similar to that of the screw driving blade projecting from an opposed end. Optionally, the body encloses torque limiting components limiting torque applied to the screw driving blade. The screw driving blade may be polygonal. The cutting blade may be a fluted drill bit. Where the torque limiting components are not provided, the body may bear external splines, with the screw driving blade and cutting blade being monolithic with the body.
摘要:
A minimally invasive tissue incision system for creating joint capsulotomies and releasing/incising various tendon and fibrous band structures. The system contains a penetrating needle which is retractable so as to expose a cutting element, and which may be used as a penetrating needle to pierce the skin and other soft tissue structures. The cutting element provided within the penetrating needle may be used to incise subsequent tissue structures after the initial penetration. The system facilitates such procedures by providing the cutting element with the confines of the needle which provides safe introduction of the cutting element directly to the site via the needle.
摘要:
Membrane forceps for performing an ILM or ERM peel procedure include a handle, a tube extending from the handle, and forceps jaws extending from the tube. The forceps jaws may be configured to grasp an ILM or ERM, and may include an outer surface having a roughened surface. The roughened surface may be structurally configured to aid in gaining an edge of the ILM or ERM.
摘要:
Methods and apparatuses are disclosed for the diagnosis and removal of the devitalized and/or dead cell material formed in the lid margin to attempt to restore a normal lid margin. In this manner, the devitalized and/or dead cell material are removed or the amount present is reduced or no longer present to prevent, reduce, or affect the transport of lipid secreted by the meibomian glands to the tear film to reduce evaporative dry eye and improve dry eye conditions in patients. The diagnosis and removal of devitalized and/or dead cell material may be performed at desired intervals. Patients that suffer from conditions that block meibomian gland orifices, partial, infrequent, or inhibited blinking resulting in reduced lipid secretions from meibomian glands, and/or blockages in meibomian gland channels reducing secretion of lipids through the meibomian gland orifices may require more frequent diagnosis and treatment to remove devitalized and/or dead cell material.
