Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor laser instruments, in particular to semiconductor laser instruments. Background Art

[0002] A semiconductor laser is a medical device that uses semiconductor laser technology to treat the human body. It transmits energy to human tissue by emitting laser beams to promote tissue repair and pain relief. Semiconductor lasers have the characteristics of non-invasiveness, painless treatment and high efficiency.

[0003] At present, the existing semiconductor lasers lack protective measures. Because there are many people coming and going in hospitals and the hospital is messy, the semiconductor laser itself is equipped with auxiliary moving devices such as rollers for easy movement, but the rollers are not limited or the limiting effect is poor. Then, when a patient accidentally touches the semiconductor laser body, the semiconductor laser will move under the action of the rollers and it is easy to collide with the wall. In addition, the laser probe and operation screen of the semiconductor laser are exposed all year round. Therefore, when a patient or a young child accidentally touches the semiconductor laser, the probe of the semiconductor laser is easily damaged.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing semiconductor laser instruments on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which makes it impossible to achieve the desired effect.

Spring 2116, the left ends of the two force-bearing springs 2116 are fixedly connected to the right side of the protective plate 2115, a circular groove 2103 is opened on the upper surface of the laser instrument body 1, and a display screen 2101 is fixedly connected to the inner wall of the laser instrument body 1. By setting a protection unit 21, the protection unit 21 can be used to provide protection for the probe 2105 and the display screen 2101 in the laser instrument body 1 to prevent the two from being damaged and unusable due to collision due to external factors. At the same time, it can also ensure that when the two are not in use, no dust will be adsorbed on the surface of the probe 2105 and the display screen 2101.

[0024] See also Figure 1 and Figure 2 The inner wall of the laser body 1 is rotatably connected to a limit ring 2102, the bottom surface of the laser body 1 is fixedly connected to two universal wheels 2108, and the left side of the laser body 1 is fixedly connected to two control buttons 2107. The limit ring 2102 can be used to limit the upper and lower positions of the probe 2105, the universal wheels 2108 can be used to push the device to turn and move, and the control buttons 2107 can be used to control the operation of the device.

[0025] See also Figure 2 A circular opening 2109 is provided on the upper surface of the laser body 1, and a circular block 2110 is clamped inside the circular opening 2109. By providing the circular opening 2109 and the circular block 2110, and by utilizing the relationship that the circular block 2110 is clamped inside the circular opening 2109, the fixing frame 2106 can be disassembled and replaced.

[0026] See also Figure 1 and Figure 2 The top of the circular block 2110 is fixedly connected to a fixing frame 2106, the upper surface of the laser body 1 is fixedly connected to a probe 2105, the outer surface of the probe 2105 is snapped into the inside of the fixing frame 2106, and the fixing frame 2106 is provided to provide a temporary supporting force for the probe 2105.

[0027] See also Figure 4 Two rectangular grooves 2117 are provided on the inner wall of the laser body 1, and a rectangular slider 2118 is slidably connected to the inside of each rectangular groove 2117. The sides of the two rectangular sliders 2118 that are close to each other are fixedly connected to the front and back sides of the protective plate 2115 respectively. By providing the rectangular grooves 2117 and the rectangular sliders 2118, and utilizing the relationship between the rectangular sliders 2118 sliding inside the rectangular grooves 2117, it can be ensured that when the protective plate 2115 is subjected to pressure, the pressure can be transferred to the rectangular sliders 2118, thereby avoiding damage to the display screen 2101.

[0028] The specific implementation method of this embodiment is as follows: when the device is needed, the device can be pushed to a suitable position. After the device is moved to a suitable position, the probe 2105 can be removed from the fixing frame 2106, and then the control button 2107 can be used to control the operation of the device. It should be understood here that since the probe 2105 needs to be connected to the device inside the laser instrument body 1 using a wire, the bottom end of the probe 2105 is fixed on the laser instrument body 1. In addition, the probe 2105 can be snapped onto the fixing frame 2106 or inserted into the circular groove 2103. When medical staff need to temporarily stop the operation of the device, the probe 2105 can be snapped onto the fixing frame 2106 to provide temporary support for the probe 2105. When the device is used up and the probe 2105 needs to be protected, the probe 2105 is inserted into the circular groove 2103 provided on the upper surface of the laser instrument body 1. When the probe 2105 enters the circular groove 2103, it will first contact with the outer surfaces of the first rotating shaft 2111 and the second rotating shaft 2112. Since the outer surfaces of the first rotating shaft 2111 and the second rotating shaft 2112 are covered with a layer of rubber pad, it can not only provide protection for the surface of the probe 2105, but also increase the friction between the probe 2105 and the surfaces of the first rotating shaft 2111 and the second rotating shaft 2112, so that the probe 2105 can stably drive the first rotating shaft 2111 and the second rotating shaft 2112 to rotate, and the second rotating shaft 2112 is in contact with the outer surfaces of the first rotating shaft 2111 and the second rotating shaft 2112. When the first rotating shaft 2111 rotates, it will drive the first rotating shaft 2121 and the second clamping block 2122 fixed on its surface to rotate, so that the second clamping block 2122 rotates to the outside of the second clamping groove 2123. When the probe 2105 is completely inserted into the circular groove 2103, the second clamping block 2122 and the second clamping groove 2123 are no longer in a clamping relationship. The rotation of the first rotating shaft 2111 will drive the first transmission rope 2113 fixed on its surface to rotate, so that the first transmission rope 2113 is wound around the surface of the first rotating shaft 2111. As a result, the first transmission rope 2113 will pull the first clamping block 2120 to move downward until the first clamping block 2120 is completely moved downward to the inside of the laser instrument body 1 and is no longer in a clamping relationship with the first clamping groove 2119. At this time, the protective plate 2115 is no longer restricted by the first block 2120 and the second block 2122, so the protective plate 2115 will be pushed to move by the force spring 2116 until the protective plate 2115 completely covers the top of the display screen 2101. It should be understood here that when the laser body 1 is in use, the force spring 2116 is always in a compressed state, and the protective plate 2115 will use the rectangular sliders 2118 fixed on the front and back to slide inside the rectangular slide groove 2117 when moving. Therefore, when the protective plate 2115 is subjected to external pressure, the pressure will also be transferred to the rectangular slider 2118, so that it will not act on the surface of the display screen 2101 and damage the display screen 2101.

[0029] Example 2: Please refer to Figure 1 , Figure 2 and Figure 9-14 The present invention provides a technical solution: a semiconductor laser instrument. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The protection mechanism 2 also includes a limiting unit 22, which is arranged on the outside of the laser instrument body 1. The limiting unit 22 cooperates with the protection unit 21, and the limiting unit 22 can limit the device to stop moving.

[0030] As a further limitation of the protection mechanism 2 of the present invention, the limiting unit 22 includes a winding drum 2211, the left end of the winding drum 2211 is fixedly connected to the right end of the first rotating shaft 2111, the outer surface of the winding drum 2211 is fixedly connected to the second transmission rope 2213, the bottom end of the second transmission rope 2213 is fixedly connected to the lifting frame 2214, the right side of the laser instrument body 1 is fixedly connected to two rectangular blocks 2216, the upper surface of each rectangular block 2216 is fixedly connected to the second return spring 2215, the top ends of the two second return springs 2215 are fixedly connected to the bottom surface of the lifting frame 2214, the bottom surface of the lifting frame 2214 is fixedly connected to two first transmission plates 2203, the outer surface of each first transmission plate 2203 is rotatably connected to the first folding plate 2210, the front and back sides of the laser instrument body 1 are fixedly connected to the first limit frame 2202 and the second sliding frame 2205, the outer surface of each first transmission plate 2203 is slidably connected to the inside of the first limit frame 2202, each The interior of each second sliding frame 2205 is slidably connected with a second transmission plate 2219, and the outer surface of each second transmission plate 2219 is rotatably connected with a second folding plate 2209. The inner wall of each first folding plate 2210 and the inner wall of the second folding plate 2209 are rotatably connected with a rotating plate 2204. The inner wall of each rotating plate 2204 is fixedly connected with a short shaft 2217, and the outer surface of each short shaft 2217 is rotatably connected to the inner wall of the laser instrument body 1. The inner wall of the laser instrument body 1 is rotatably connected with two rollers 2207, and the outer surface of each roller 2207 is fixedly connected with a first roller 2208. The ends of the two first rollers 2208 that are away from each other are fixedly connected with a first gear 2206. By providing a limiting unit 22, the movement of the first roller 2208 can be limited by the limiting unit 22, so that when the laser instrument body 1 is not in use, there will be no patient or child pushing the laser instrument body 1 to move, so that the laser instrument body 1 collides with the wall and causes damage.

[0031] See also Fig. 9The inner wall of the laser body 1 is rotatably connected with a rotating shaft 2212, and the outer surface of the rotating shaft 2212 contacts the outer surface of the second transmission rope 2213. By providing the rotating shaft 2212, the rotating shaft 2212 can provide support force for the second transmission rope 2213, and the rotational connection between the rotating shaft 2212 and the laser body 1 can reduce the friction force on the second transmission rope 2213 when it moves.

[0032] See also Fig. 9 and Fig.11 T-shaped grooves 2201 are provided on the front and back of the laser body 1, and a T-shaped slider 2218 is slidably connected inside each T-shaped groove 2201. The sides of the two T-shaped sliders 2218 that are away from each other are fixedly connected to the side of the lifting frame 2214 close to the laser body 1. By providing the T-shaped slider 2218 and utilizing the connection relationship of the T-shaped slider 2218 sliding inside the T-shaped groove 2201, the lifting frame 2214 can be limited so that the lifting frame 2214 can only move up and down.

[0033] The specific implementation of this embodiment is as follows: when the probe 2105 pushes the first rotating shaft 2111 downward to rotate, the first rotating shaft 2111 will transmit power to the top of the winding drum 2211, thereby driving the winding drum 2211 to rotate, so that the winding drum 2211 can reel in the second transmission rope 2213 fixed on its surface, thereby the lifting frame 2214 can be pulled upward by the second transmission rope 2213, and the lifting frame 2214 will drive the second return spring 2215 fixed on the bottom surface to stretch when moving upward, and the two first transmission plates 2203 fixed on the bottom surface of the lifting frame 2214 will also move upward synchronously, and when the first transmission plate 2203 moves upward, it will drive the first folding plate 2210 connected to its surface to move upward synchronously, and there is a certain angle between the first folding plate 2210 and the first transmission plate 2203. Therefore, while the first transmission plate 2203 drives the first folding plate 2210 to move upward, the first folding plate 2210 will gradually be in the same vertical line with the first transmission plate 2203. Therefore, the first folding plate 2210 will pull the rotating plate 2204 to rotate counterclockwise. When the rotating plate 2204 rotates counterclockwise, the second folding plate 2209 rotatably connected to its outer surface will also move downward and gradually be in the same vertical line with the second transmission plate 2219. Therefore, the second folding plate 2209 will push the second transmission plate 2219 to move downward until it engages with the teeth on the surface of the first gear 2206, limiting the rotation of the first gear 2206 and the first roller 2208, thereby limiting the movement of the laser body 1, thereby avoiding the problem that the laser body 1 is moved due to accidental contact with the patient, and finally collided and damaged.

[0034] Example 3: Please refer to Figure 2 and Figure 14-16 The present invention provides a technical solution: a semiconductor laser instrument. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0036] The specific implementation of this embodiment is as follows: the second transmission plate 2219 will also push the transmission shaft 305 to move downward synchronously during the downward movement, and the connecting block 309 fixed at one end of the transmission shaft 305 and the second rotating shaft 311 slidably connected to the inner wall of the connecting block 309 will also move downward synchronously, and at the same time, the sliding plate 310 fixed on the outer surface of the second rotating shaft 311 will also move downward with the connecting block 309, and eventually the lower half of the sliding plate 310 will enter the rotating track of the second gear 302, and at this time the sliding plate 310 is still inside the knocking plate 307. It should be understood here that the lower half of the sliding plate 310 refers to the lower half separated by the second rotating shaft 311 as the center. When a patient wants to forcibly move the laser instrument body 1, The first roller 2208 will not rotate, but as the patient continues to apply thrust, the first roller 2208 will slide on the floor, but the second roller 303 will rotate. When the second roller 303 rotates, it will drive the second gear 302 fixed on the inner wall to rotate. When the second gear 302 rotates, the teeth fixed on its surface will push the sliding plate 310 and the knocking plate 307 to rotate around the spiral cylinder 306 as the center of the circle, and the second rotating shaft 311 will slide inside the connecting block 309. When the knocking plate 307 rotates, the spiral cylinder 306 fixed on its inner wall will also rotate, and the spiral grooves on the inner wall of the spiral cylinder 306 correspond to the spiral strips fixed on the surface of the spiral shaft 312. Therefore, when the spiral cylinder 306 rotates, the spiral grooves on its inner wall will push the spiral cylinder 306 to rotate. The spiral strip of the rotating shaft 312 and the spiral shaft 312 move toward the position of the third return spring 315, thereby squeezing the third return spring 315. However, when one of the teeth of the second gear 302 is no longer in contact with the sliding plate 310, the sliding plate 310 is no longer subjected to thrust. Similarly, the spiral cylinder 306, the spiral shaft 312 and the third return spring 315 will not be restricted. The third return spring 315 will push the spiral shaft 312 to reset. When the spiral shaft 312 is reset, it will also push the spiral cylinder 306 to rotate in the opposite direction, thereby driving the knocking plate 307 to rotate in the opposite direction. Under the action of inertia, the knocking plate 307 will drive the knocking block 308 to hammer the inner wall of the struck frame 301, thereby sending out an alarm signal. At this time, the probe 2105 has been installed. The rotatable limiting ring 2102 is rotated to the top of the probe 2105, and the limiting ring 2102 is used to limit the probe 2105. When the medical staff wants to use the laser instrument body 1, they first push the protective plate 2115 to squeeze the first reset spring 2125, and then pull the probe 2105 out with the other hand. When the probe 2105 comes out, the reaction force acting on the first rotating shaft 2111 and the second rotating shaft 2112 will drive the first clamping block 2120 and the second clamping block 2122 to be re-clamped inside the first clamping groove 2119 and the second clamping groove 2123, and the winding drum 2211 will rotate in the opposite direction to release the wire, so the lifting frame 2214 will stop being subjected to tension, and the second reset spring 2215 will pull the lifting frame 2214 to reset.After a series of force transmission, the second transmission plate 2219 finally moves upward, stops limiting the first gear 2206, and the second transmission plate 2219 drives the sliding plate 310 to move upward. At this time, the rotation of the second gear 302 will not drive the sliding plate 310 to rotate. Then the medical staff can clamp the probe 2105 on the fixing frame 2106 to provide a short-term support force for the probe 2105, and then push the device to the patient's bedside for use.
