Abstract

The present invention relates to a luminaire designed to shine light on an affected part by attaching it to an incision holding device called a retractor, which is frequently used in an incision procedure on a human body. It is a disposable light medical device that can be inserted into the shape of a clip at the end of the retractor's blade to keep the light on and illuminate the affected area with its own lighting, and then discard it after use.

Description

 Clip type medical light fixture that can be attached and detached {Clip type LED lights for surgical retractor}

The present invention relates to a luminaire designed to shine light on an affected part by attaching it to an incision holding device called a retractor, which is frequently used in an incision procedure on a human body. It is a disposable lighting medical device that can be inserted into the form of a clip at the end of the blade portion of the retractor that maintains the light to illuminate the affected area by self-disposal and discarded after use. If you want to reuse, you can use it after cleaning by disinfection through EO gas or gamma irradiation.

In general, a surgical forceps called a retractor made of metal is used to keep the skin open in a laparotomy in which the abdomen is opened and operated. The device is attached to a wide plate called a blade, which covers the patient's affected area to keep it from closing again. However, this blade called blade must maintain a very thick thickness in order to maintain a skin incision and maintain the incision aside from the deep part. As a result, the light of the shadowless light is often hidden by the blade so that it is difficult to see. Conventionally, in this case, the xenon lamp or the shadowless lamp used to be mounted on the operator's head is used for adjustment, but in this case, the problem arises that the xenon lamp is kept on the operator's head or the shadow is generated even when the shadowless lamp is operated.

  The problem to be solved in the present invention is to attach a small light fixture in the form of a clip on the blade portion of the blade to remove the shadow caused by the blade of the retractor and the operator's head or hands to maintain the patient's skin incision state during the procedure To shed light on the deep and affected areas. This compact luminaire consists of a built-in battery, a number of white LEDs, and a PCB circuit to build it. In addition, in order to prevent the battery and internal circuits from being leaked by the body fluid, it is mounted in the airtight case and coated with a hydrophobic material on the surface of the LED in order to prevent performance degradation of the LED light by various pollutants, in particular, the body fluid. We want to prevent performance degradation.

  The present invention is configured to the lighting fixture using a white LED and a built-in battery and put in a plastic case having a concave-convex clip in order to prevent external pollution, while protecting the circuit to be mounted on the blade portion of the blade to illuminate the core and affected areas It is configured in the form of providing.

 When the product according to the present invention is used, shading by various instruments or shading by the operator's hand or head is removed, which helps the operator to perform the procedure more easily, thereby reducing the procedure time. This has the advantage of reducing risk.

1: general medical retractor
2: blade attached to medical retractor
3: Anti-shake protruding jaw
4: outer case for circuit protection
5: Concave-convex clip
6: LED for light source
7: switch for operation

In order to embody the present invention, a white LED 6 having high efficiency compared to an operating power source was used, and a battery used a Ni-Cd type. In the case of the battery which occupies the most space, it is positioned outside of the blade 2 and protected by a sealed case 4 in order to prevent a short circuit caused by body fluid.The clip is attached to the bottom of the circuit where the LED is mounted. As it is pressed, the button switch 7 is started to operate when it is pressed, so that it is simply operated by coupling to the blade (2). In addition, in order to prevent the phenomenon of moving away from the movement or impact during use or to move to the other side was formed so as to prevent the movement by forming a protruding jaw (3) in the middle of the outer case.

Claims (2)

In the medical retractor that maintains the incision state of the affected area during surgery,
Medical luminaire consisting of a plurality of LEDs in the form of clips to be mounted on the blade, the end The method according to claim 1,
Medical luminaires with operation switches in the form of buttons that can be operated automatically when the clip is attached to the back of the operation switch
