Description

Surgical expansion device

The present invention relates to a surgical aid, and more particularly to a surgical distraction device having an illumination effect.

When performing a thoracotomy or open surgery, the distractor must be used to open the wound to fully reveal the surgical field and secure the opening of the wound. Commonly used spreaders (or tractors) are divided into two types: hand-drawn and automatic mechanical pull-open type, which are pulled at the same time in a multi-point manner at the opening of the wound. However, the above method is quite easy because of uneven application of force, resulting in further strain of muscle tissue at the wound. Furthermore, in addition to using the spreader to open the wound to fully reveal the surgical field of view, an appropriate auxiliary lighting device is additionally required to clearly observe the condition of the patient in order to accurately perform the surgical treatment.

In order to achieve both the distraction effect and the illumination, there is a "surgical aid" disclosed in the publication of the Republic of China No. 201302148. The surgical aid includes an outer ring reel 11 , a lighting unit 12 spaced apart from the outer ring reel 11 , and a distraction ring film 13 between the outer ring reel 11 and the illumination unit 12 . As shown in FIG. 2, in use, the lighting unit 12 is flexed into a flat strip shape and then placed by the slit 100 of the wound, so that the lighting unit 12 is located in the body, and the outer ring winding member 11 is located in the body. In addition, the outer ring reel 11 is further wound up to tighten the distraction ring film 13 to open the incision 100, and provide illumination effect through the illumination unit 12 located in the body, thereby making the operation more complete. Convenience.

The lighting unit 12 can be a ring body 121 made of a light-transmitting material and having a hollow shape, a flexible circuit board 122 disposed in the ring body 121, and The plurality of light-emitting diodes 123 are disposed on the flexible circuit board 122, or the light-emitting diode body 12 includes a hollow ring body 121 disposed in the ring body 121. The optical fiber 124 and a light emitting diode 125 disposed at one end of the optical fiber 124. Although the above design can have both the distracting effect and the illumination, as shown in FIG. 1 and FIG. 3, the LEDs 123 and 125 emit high heat when used, so the ring body 121 also needs to be filled with the heat absorbing fluid. The inlet tube 14 and the outlet tube 15 for circulating the heat absorbing fluid are disposed on the ring body 121, so that the overall design is more complicated and the use is not convenient. Moreover, in the process of placing the illumination unit 12 in the body, the deflection of the illumination unit 12 may also cause damage to the flexible circuit board 122 or the optical fiber 124, thereby causing the illumination unit 12 to be inoperable and affecting the operation. . In addition, the light-emitting diodes 123 and 125 necessarily need to be powered by a power source (not shown) to emit light, and the above design will cause the power supply to be placed in the body, which may cause electric shock or leakage during the operation, and may also invade. Concerns about the safety of electrical appliances.

Accordingly, it is an object of the present invention to provide a surgical distraction device that enhances the safety of use.

Thus, the surgical distraction device of the present invention comprises a distracting unit and a light emitting unit capable of guiding light to the distracting unit. The expansion unit includes an upper ring, a lower ring spaced apart from the upper ring and having a light source lead-in area, and an elastic film connecting the upper and lower rings. The light emitting unit comprises a light source and at least one light guiding strip connected to the light source and capable of guiding the light of the light source. The light guiding strip is removably connected to the light source lead-in area to guide the light of the light source to the lower ring via the light source lead-in area, so that the lower ring has an illumination effect.

The utility model has the advantages that the disengagement unit and the illumination unit are separated from each other, and the illumination structure and the surgical distraction function are combined to make the overall structure more compact and to improve the safety of use.
