Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a medical mirror hook.

[0002]

[Prior art]

 Medical mirror hooks are used to compress and expand tissues and muscles in the surgical site during surgery, etc., and connect a relatively long connecting part (bar) to the tip of the gripping part. Then, the structure is such that a mirror is placed at the tip of the connecting part, and by observing the tilted mirror surface by positioning the line of sight along the connecting part (bar) while holding the gripping part. It is used to capture the target area within the visual field.

[0003]

[Problems to be solved by the device]

 By the way, the mirror hook has a mechanism for observing the tissue, muscles, etc. of the surgical site by reflecting light from the outside with a mirror body, and the mirror body itself is extremely small with a diameter of 3 to 5 mm. In addition, depending on the direction of the mirror hook, light may not reach, the part to be observed may be difficult to see, or even dazzle because the external light source enters the field of view through the mirror. There was a problem that reliability was poor as a surgical instrument for the sake of safety. In addition, there is a performance problem that cannot be observed at all in the dark part such as the back side of the tissue where the light does not reach, and improvement has been desired.

The present invention has been made in view of the above-mentioned conventional circumstances, and its technical problem is to illuminate an inclined mirror surface from a position approaching in the same direction as the line-of-sight direction and illuminate an observation target site with the reflected light. By providing such a function, it is possible to provide a medical mirror hook that enables clear observation of any observation target location.

[0005]

[Means for Solving the Problems]

 The technical measures taken to achieve the above-mentioned object are: a grasping part, a connecting part connected to the grasping part, a medical mirror hook main body composed of an inclined mirror surface arranged at the tip of the connecting part, and its The gist of the present invention is to have an optical fiber group which is attached to a connecting portion of a main body of a medical-use hook and which has an outlet opening near the inclined mirror surface and which connects the inlet to a light source means.

[0006]

[Action]

 According to the above technical means, the light from the optical fiber group is irradiated toward the inclined mirror surface at the tip of the connecting portion from the position in the same direction as the line-of-sight direction and approaching, and the reflected light illuminates the observation target site.

[0007]

[Effect of device]

 Since the present invention is a medical mirror hook adapted to irradiate light from the optical fiber group from a position in the same direction as the line-of-sight direction and close to the inclined mirror surface at the tip of the connecting portion, the light can be emitted at any time. It is possible to provide a medical mirror hook capable of irradiating a tilted mirror surface accurately and surely for observation and enabling clear observation even in a dark portion on the back side of a tissue. Moreover, the line of sight to the tilted mirror surface and the optical axis that illuminates the tilted mirror surface are coaxial, and the illumination light is applied to the mirror surface, and the reflected light illuminates the observation target site, so the reflected light is used. It is possible to reliably prevent the dazzling caused by all or part of the illumination light entering the field of view when directly illuminating the observation target region without doing so. Further, since the illumination light to the inclined mirror surface is diffused and diffusely reflected, it is possible to obtain necessary and sufficient optimum illumination for the visual field by using the inclined mirror surface itself as a reflector for illumination.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. 1 to 3 show a medical hook according to this embodiment.

The medical mirror hook A is composed of a medical mirror hook main body 1 and an optical fiber group 2 attached to the medical mirror hook main body 1 and connected to the light source means B.

The medical mirror hook body 1 is a well-known medical device including a grip portion 11, a relatively long connecting portion 21 at the tip of the grip portion 11, and an inclined mirror surface 31 integrated with the tip of the connecting portion 21. It is configured in the same manner as the mirror mirror hook.

The optical fiber group 2 is focused, and has one end, that is, an inlet side to which a connector 51 connected to a light source means B described later is connected, and the other end, the outlet, is brought close to the inclined mirror surface 31. The medical hook body 1 is attached with the specific wiring structure shown in FIGS. 1, 2 and 3.

Next, referring to each drawing, FIG. 1 shows that the grip portion 11, the connecting portion 21, and the flexible synthetic resin or rubber for connecting the grip portion 11 and the connector 51 to each other. All the flexible parts 41 such as are formed in a hollow shape, and the optical fiber group 2 is internally inserted in the holding part 11, the connecting part 21, and the flexible part 41, and the outlet is brought close to the inclined mirror surface 31. The light supplied from the light source means B irradiates the inclined mirror surface 31 from an oblique direction.

2 and 3 show a case where the optical fiber group 2 is attached to the connecting portion 21. Specifically, FIG. 2 shows a case where the flexible part 41 accommodating the optical fiber group 2 is attached to the connecting part 21 and the gripping part 11. In FIG. 3, the flexible part 41 adjacent to the side surface of the connecting part 21 is shown. The figure shows a case where a predetermined range of the end of the optical fiber group 2 is inserted into the inner hollow connecting part 21 from the end on the outlet side.

Although not described in detail, the light source means B is a commercially available fiber light source device including a light source lamp (for example, a halogen lamp) or a commercially available fiber light source device including a mirror condenser light source lamp (for example, a halogen lamp). Is.

Therefore, in this embodiment, by only connecting the connector 51 to the light source means B and activating the light source means B, the light supplied from the light source means B can be moved from a position close to the optical fiber group 2. The tilted mirror surface 31 at the tip is irradiated to enable clear observation of tissues, muscles 100, etc. At that time, as shown in FIG. 1, the irradiation range X of the illumination light from the optical fiber group 2 reflected by the inclined mirror surface 31 is wide, and within the irradiation range X, the line of sight directed in the same direction as the optical axis 3 The visual field range Y of 4 can be secured.

The feature of the medical mirror hook of the present embodiment is that the light source means B and the medical hook main body 1 are connected by using the flexible portion 41, so that the mobility of the medical hook main body 1 is improved. It does not interfere at all, it can be removed from the light source means B when it is not used, and it is compactly rolled so that the storage space is not unnecessarily occupied.

Further, when the wiring structure of the optical fiber group 2 shown in FIG. 1 is adopted, it is possible to maintain the original easiness of grasping the medical hook.
