Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to a drill device with an endoscope that allows accurate drilling work to be performed while viewing the image of the object to be drilled at the tip of the drill. [Prior Art] Generally, when drilling holes in the human body such as the stomach or bones during surgery, a medical drill device is used. With conventional drilling equipment, the image of the object to be drilled at the tip of the drill cannot be seen, so the location of the object to be drilled has to be carefully considered before performing the drilling operation. [Problems to be Solved by the Invention] However, there has been a problem in that conventional drilling devices cannot completely satisfy the requirements for drilling work on the human body that requires precision. In order to solve the above-mentioned problems, the present invention aims to provide a drill device with an endoscope that allows accurate drilling work to be performed while viewing the image of the object to be drilled at the tip of the drill. . [Means for Solving the Problems] In order to solve the above problems, the drill device with an endoscope according to the present invention includes a casing in which a handle is formed, and a drive rotatably supported by the casing and built in the casing. A hollow rotating part that is rotationally driven by a device, a hollow drill removably attached to the tip of the rotating part concentrically with the rotating part, and a hollow drill that is inserted through the hollow part of the rotating part and The rotating part and the drill are rotatably supported via a bearing provided on the outside, and the endoscope has a rear end fixed to the casing. The endoscope is configured to include a hollow body, two lenses provided at the tip and rear ends of the body, and a fiberscope with end surfaces of both ends facing the two lenses. good. Alternatively, the endoscope may be configured to include an eyepiece for direct viewing that is attached to the rear end side of the endoscope. Furthermore, a television camera device connected to a television monitor may be attached to the rear end of the endoscope. [Function] In the present invention, first, an eyepiece for direct viewing is attached to the rear end side of the endoscope fixed to the casing.
Look through the eyepiece and see the object to be drilled at the tip of the drill. After moving the drill to the correct position, the rotary part is driven to rotate to perform drilling work. In addition, if a television camera device connected to a television monitor is attached to the rear end of the endoscope, the video signal from the television camera device is sent to the television monitor, so the image of the tip of the drill is displayed on the television monitor. be able to. Therefore, drilling work can be performed while viewing the tip of the drill on a television monitor. [Embodiment] An embodiment of the drill device A of the present invention will be described below based on the drawings. FIG. 1 is a side sectional view showing the configuration of the drill device of the present invention, FIG. 2 is a detailed view of the drill in the drill device of the present invention, and FIG. 3 is an explanatory diagram showing another embodiment of the drill device of the present invention. It is. In FIG. 1, reference numeral 1 denotes a casing, and a handle portion 2 is formed on the lower side of the casing 1 to be gripped when drilling. This handle portion 2 has a built-in motor 3. A rotary part 4 is rotatably supported on the upper side of the casing 1 from the inside to the outside. The outer rear end portion 4' of this rotating portion 4
The distal end portion 3a' of the drive shaft 3a of the motor 3 and the drive shaft 3a of the motor 3 are formed in the shape of gears, and are meshed with each other, so that the rotating portion 4 is rotationally driven by the rotational drive of the motor 3. 3b is a bearing of the drive shaft 3a, and 5 is a bearing of the rotating part 4. A drill chuck 6 is provided at the tip of the rotating part 4. This drill chuck 6 is an existing one which is constructed by connecting a female thread or a pawl to a main body, and is removably attached by tightening a hollow drill 7 with a chuck handle. The drill 7 is available in various sizes and sizes, and is selected depending on the object to be drilled by the drill device A. 8 is inserted into the hollow part of the rotating part 4 and the drill 7 and rotatably supports the rotating part 4 and the drill 7 via an oilless bearing 8' provided on the outside;
This is an endoscope whose rear end is fixed to a casing 1.
Inside the endoscope 8, as shown in FIGS. 1 and 2, a fiber scope 8b made of a glass material is installed in a hollow body 8a in a horizontally elongated manner. Further, an objective lens 8c is attached to a position close to the front end surface of the fiberscope 8b in order to transmit an image of the object to be drilled to the fiberscope 8b, slightly inside the tip of the body 8a. Note that the objective lens 8c may be configured to be movable left and right to adjust the focus. Further, a fiber scope 8b is installed on the rear end side of the body 8a in order to magnify the image of the drilling target transmitted by the fiber scope 8b.
An eyepiece lens 8d is attached to a position close to the rear end surface. Reference numeral 9 denotes an eyepiece for directly viewing the image at the tip of the drill 7, and the tip of the eyepiece 9 is removably fitted to the rear end of the endoscope 8. In order to brightly illuminate the object to be drilled, a miniature light bulb may be attached to the distal end of the endoscope 8, or a light guide may be built in to guide light from an external power source to the distal end. Next, the operation when performing drilling work using the drill device A of the present invention will be explained. First, the eyepiece 9 is inserted into the rear end of the endoscope 8.
Then, an objective lens 8c attached to the tip side of the endoscope 8 magnifies the image of the object to be drilled at the tip of the drill 7, and the fiberscope 8b transmits the image from one end surface of the fiberscope 8b to the other end surface. do. This transmitted image is then magnified by an eyepiece 8d attached to the rear end of the endoscope 8. Then, while viewing the image through the eyepiece 9, the drill device A is moved so that the tip of the drill 7 is positioned at an appropriate position to perform drilling work. The present invention is not limited to the embodiments having the above-described configuration. For example, as shown in FIG. 3, a television camera device 10 is connected to an endoscope 8 of a drill device A, The control device 12 may be connected to a control device 12 via a cable 11, and the control device 12 may be connected to a television monitor 14 via a second cable 13. With the above configuration, the television camera device 1
The electric signal from the drill 7 is amplified by the control device 12 and becomes a video signal, and this video signal is sent to the television monitor 14, so that the image of the tip of the drill 7 can be displayed on the television monitor 14. Therefore, since the drilling work can be performed while viewing the image of the tip of the drill 7 on the television monitor 14, more accurate drilling work can be performed. The present invention can be applied not only to medical drill devices but also to general drill devices that require accurate drilling operations. [Effects of the Invention] According to the present invention, drilling work is performed while directly viewing the object to be drilled at the tip of the drill through an endoscope or while viewing a television monitor connected to the endoscope. , can perform accurate drilling work.
