As shown in Figure 1, the surgical power tool 100 has a built-in motor, a main body 110 with a tool mounting portion 111 formed on the front and a handle 113 formed downward, and a handle of the main body 110 ( 113) The battery 120 is inserted inside, the battery cover 130 is mounted on the bottom of the handle 113 of the main body 110 to prevent the battery 120 from falling off, and is mounted on the battery cover 130 to prevent errors. It includes a double locking portion 140 that prevents the battery cover 130 from being separated.

In the surgical power tool 100 configured as described above, when the medical staff intentionally presses the two separation buttons 131 installed on both sides of the battery cover 130 at the same time, the battery cover 130 can be separated from the main body 110. In this state, the medical staff separates the battery cover 130 from the handle 113 and pulls out the battery 120 built into the handle 113 out of the handle 113.

However, if the two release buttons 131 are unintentionally pressed at the same time while holding and using the handle 113 of the surgical power tool, the unlocked battery cover 130 is attached to the handle 113 because the handle is being held. It falls downward due to the weight of the built-in battery 120, and at the same time, the battery 120 also falls downward.

In the present invention, the double locking part 140 is installed so that the battery cover 130 is not separated from the main body 110 even if the release button 131 of the battery cover 130 is pressed due to an error, thereby ensuring sterilization. It is possible to prevent untreated batteries 120 from falling into the sterilization area.

According to the purpose of the present invention, the double locking part can be applied to other surgical power tools that have a structure in which the battery is dislodged by load as the battery cover is separated from the main body, even if the shape and form are different.

Below, the configuration of the double locking portion and its operational relationship will be described in detail using the surgical power tool shown in FIG. 1 as an example.

As shown in Figures 2 to 4, the main body 110 of the surgical power tool 100 has a handle 113 formed downward and a tool mounting portion 111 formed forward. The tool mounting portion 111 is configured to replace and mount various tools (T), and the handle 113 extends downward so that the tool (T) is positioned forward when the medical staff grips the handle 113. do.

The handle 113 has a hollow structure, and the lower end of the handle 113 is open.

The battery 120 is inserted into the handle 113 with the bottom open, and the battery cover 130 is mounted on the bottom of the handle 113 while the battery 120 is inserted into the handle 113.

When the battery cover 130 is installed, the battery 120 is located inside the handle 113 and provides power required to operate the power tool 100.

Meanwhile, looking in detail at the structure of the battery cover 130, the battery cover 130 has an opening 133 formed on its upper surface, and the bottom of the handle 113 is formed through the opening 133 of the battery cover 130. This is inserted and installed.

Two separation buttons 131 are formed on the side of the battery cover 130. The middle of the separation button 131 is hinged to the battery cover 130, and when one side of the separation button 131 is pressed, the other side rotates so that it protrudes out of the outer surface of the battery cover 130, and the battery cover 130 is held by the handle. (113) It becomes unlocked and detachable from the bottom.

The reason why two separation buttons 131 are formed on the battery cover 130 in this way is to prevent the battery cover 130 from being separated even if either of the separation buttons 131 is pressed. That is, for safety reasons, the battery cover 130 can be separated from the bottom of the handle 113 only when the medical staff presses the two release buttons 131 at the same time.

The present invention is equipped with a double locking part 140 to have a safer structure so that the battery cover 130 is not separated even if the medical staff unintentionally operates the two release buttons 131 at the same time.

Before explaining the double locking unit 140, a guide groove 135 is formed in the vertical direction on the inner surface of the battery cover 130, and a guide protrusion 115 is formed on the outer surface of the handle 113 of the main body 110. is formed.

Therefore, in order to insert the lower end of the handle 113 into the opening 133 of the battery cover 130, the guide protrusion 115 and the guide groove 135 are positioned correspondingly, and the lower end of the handle 113 is positioned in the battery cover. When inserted into the opening 133 of (130), the guide protrusion 115 enters the inside of the battery cover 130 along the guide groove 135 to be installed.

If the guide protrusion 115 and the guide groove 135 do not correspond, the lower end of the handle 113 is not inserted into the opening 133 of the battery cover 130, and the battery cover 130 is not inserted into the handle ( When the entrance (135E) of the guide groove (135) exposed to the outer surface of the handle (113) is closed while mounted at the bottom of the handle (113), two separate buttons are used to dismantle the battery cover (130) from the handle (113). Even if (131) is operated and the handle 113 is pulled out from the battery cover 130, the battery cover 130 is not separated from the bottom of the handle 113 because the entrance 135E of the guide groove 135 is closed. do.

In the present invention, the double locking part 140 primarily blocks the battery cover 130 from being separated from the bottom of the handle 113 by preventing the rotation of the separation button 131, and the entrance 135E of the guide groove 135 ) to secondarily prevent separation of the battery cover 130.

The double locking portion 140 configured in this way has the same structure as the clip 141, as shown in FIG. 3.

The clip 141 is composed of an elastic wire, a bottom portion 143 corresponding to the bottom of the battery cover 130, a shaft portion 145 bent upward on both sides of the bottom portion 143, and a shaft portion ( The upper end of the hook 145) is divided by a hook 147 bent inward, and a downwardly bent lock release portion 149 is formed in the middle of the length of the bottom portion 143.

When the clip 141 is mounted on the battery cover 130 with the battery cover 130 mounted on the bottom of the handle 113 of the main body 110, the bottom 143 of the clip 141 is connected to the battery cover 130. ) is in contact with the bottom of the And the shaft portion 145 is in contact with the separation button 131, but is in contact with the part that protrudes when the separation button 131 rotates, and the hook 147 extends beyond the top of the battery cover 130 to the guide groove 135. ) is aligned with the inlet 135E to close the inlet 135E.

Therefore, when the clip 141 is mounted on the battery cover 130, the shaft portion 145 of the clip 141 is positioned to pass the part that protrudes when the separation button 131 is operated, causing the medical staff to separate it by error. Even if the button 131 is pressed, the separation button 131 does not rotate due to the interference of the shaft portion 145 and resists the force pressing the separation button 131.

Even if the two release buttons 131 operate simultaneously and the battery cover 130 becomes removable, the hook 147 aligns with and closes the inlet 135E of the guide groove 135, causing the guide protrusion 115 to close. It interferes with the hook 147 and prevents the battery cover 130 from being separated from the bottom of the handle 113. Therefore, the clip 141 double locks the separation of the battery cover 130.

Meanwhile, the lock release portion 149 protrudes downward from the middle of the bottom portion 143 of the clip 141 and is bent to leave a gap with the bottom surface of the battery cover 130.

In order to disassemble the clip 141, the medical staff holds the handle 113 of the main body 110 and presses downward while placing the locking release part 149 on the ground, and as shown in FIG. 4, both shaft parts 145 ) opens outward, and at this time, the hook 147 also moves outward and separates from the guide groove 135, causing the clip 141 to fall off the battery cover 130.

With the clip 141 removed from the battery cover 130, the battery cover 130 can be separated from the bottom of the handle 113 of the main body 110 by pressing the two release buttons 131 at the same time as described above. there is.
