Description

Technical Field

[0001] The utility model relates to the technical field of peeling devices, in particular to a holmium laser optical fiber cutting and peeling device. Background Art

[0002] Holmium laser fiber is a specialized fiber-optic transmission system that utilizes holmium (Ho) as the laser gain medium, efficiently transmitting high-energy, high-density laser beams through optical fibers. This type of laser has a wide range of applications in medicine, industrial processing, and scientific research, and is highly sought after for its unique optical properties and ability to efficiently process specific materials.

[0003] When using holmium laser fibers in clinical urological surgeries, some energy may be deposited at the tip of the fiber, especially when used for extended periods or at high power. This energy deposition can cause thermal effects on the fiber's tip material, leading to oxidation, carbonization, or melting, ultimately resulting in a blackening of the tip. Therefore, after use, the tip of the holmium laser fiber must be cut and stripped to expose the fiber. The fiber must then be manually coiled, secured, and sterilized.

[0004] Currently, the main method of peeling is to use a stripper, but a certain amount of force is required when using the stripper, and when pulling the optical fiber, the internal fiber may be broken due to improper operation. In addition, the current length of the holmium laser fiber is about two meters, and manual winding is time-consuming. Utility Model Content

[0005] The utility model aims to provide a holmium laser optical fiber cutting and peeling device which can avoid fiber breakage during peeling and can quickly circle.

[0006] To achieve the above objectives, the technical solution of the present utility model is as follows.

[0007] A holmium laser fiber cutting and stripping device comprises a lower housing and an upper housing. Two first slide bars are mounted within the lower housing, with a first slider being slidably mounted on the outer surfaces of the two first slide bars. Two second slide bars are mounted within the upper housing, with a second slider being slidably mounted on the outer surfaces of the two second slide bars. A first spring is sleeved on the outer surfaces of the second slide bars, with the ends of the first spring respectively abutting against the inner wall of the upper housing and the second slider. The side surfaces of both the lower and upper housings are provided with a first through-slot. Mounting blocks are mounted on the outer surfaces of the first and second sliders, with the ends of the mounting blocks extending through the first through-slot to the outside thereof and being mounted with blades. Clamping blocks are mounted on the side surfaces of both the lower and upper housings. A second through-slot is mounted on the upper surface of the upper housing, with a push block mounted within the second through-slot and connected to the second slider. A connecting block is mounted on the outer surface of the push block, with a socket being disposed on the lower surface of the connecting block. A fixing mechanism is provided on the upper surface of the upper housing to engage with the socket. A vertical plate is installed on the outer surface of the upper shell, a turntable is rotatably installed on the outer surface of the vertical plate, and a plurality of positioning blocks are installed in a coaxial array on the outer surface of the turntable.

[0008] It can be seen that by sliding the push block to the side close to the clamping block and fixing it with a fixing mechanism, the holmium laser fiber can then be placed between the two blades and the two clamping blocks, and then pressing the upper shell to drive the two blades to cut the holmium laser fiber, drive the two clamping blocks to clamp the holmium laser fiber, and then release the push block. At this time, the compressed first spring pushes the blade to move, so the peeling operation can be completed. Since the two clamping blocks have a high degree of fit with the outer surface of the holmium laser fiber and always maintain a horizontal state, it can avoid the situation where the internal fiber is easily broken when manually pulled. Finally, through the setting of the turntable and the positioning block, the purpose of quickly winding the holmium laser fiber can be achieved. This device combines the functions of cutting, stripping and winding, avoids the situation where multiple tools are used in turn in the traditional way, and further improves the work efficiency of medical staff.

[0009] Furthermore, the fixing mechanism includes a guide rod and an insertion rod that vertically penetrate into the interior of the upper shell, a connecting plate is installed at the bottom of the guide rod and the insertion rod, a pressure block is installed at the top of the guide rod, and a second spring is sleeved on the outer surface of the guide rod, and the two ends of the second spring are respectively in contact with the pressure block and the upper shell.

[0010] When the push block is toggled to drive the connecting block to contact and squeeze the insertion rod, the squeezing can drive the insertion rod to retract downward and compress the second spring. When the socket moves to just above the insertion rod, the compressed second spring releases its elastic force, which can push the pressure block to move upward. Through the connection of the connecting plate, the insertion rod can be driven to push upward and inserted into the socket, thereby fixing the push block. When the pressure block is pressed downward to pull the insertion rod out of the socket, the compressed first spring can push the blade to move quickly to complete the peeling.

[0011] Furthermore, the first slider and the second slider are connected via a telescopic rod.

[0012] By setting the telescopic rod, the first slider can be driven to move synchronously when the second slider is slid, and the telescopic rod is elastic and can provide movement space when the upper shell is pressed downward.

[0013] Furthermore, inner grooves are provided at the four corners of the lower surface of the upper shell, and a connecting rod is provided inside the inner groove to limit the inner position, and the end of the connecting rod is connected to the lower shell, and a third spring is provided inside the inner groove, and the two ends of the third spring are respectively in contact with the connecting rod and the inner wall of the inner groove.

[0014] By setting the inner groove and the connecting rod, the lower shell and the upper shell can be connected into a whole, and through the elastic force of the third spring, a gap is always left between the lower shell and the upper shell, so it is convenient to place the holmium laser fiber between the two blades and the two clamps.

[0015] Furthermore, a ball bearing is provided on the top of the insertion rod.

[0016] The provision of the balls can reduce frictional resistance and improve smoothness when the connecting block and the insertion rod are squeezed.

[0017] Furthermore, a rubber pad is provided on the surface of the clamping block, and an outer surface of the rubber pad is provided with anti-slip grooves.

[0018] The provision of the rubber pad not only improves the protection capability of the holmium laser fiber, but the rubber pad, combined with the anti-slip grooves, can increase friction and further improve the clamping effect of the holmium laser fiber. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The present invention is described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown, a holmium laser fiber cutting and stripping device includes a lower housing 100 and an upper housing 101. Two first slide bars 102 are mounted within the lower housing 100, with a first slider 103 slidably mounted on the outer surfaces of the two first slide bars 102. Two second slide bars 104 are mounted within the upper housing 101, with a second slider 105 slidably mounted on the outer surfaces of the two second slide bars 104. A first spring 106 is sleeved on the outer surface of the second slide bars 104, with the ends of the first spring 106 abutting against the inner wall of the upper housing 101 and the second slider 105, respectively. First through-slots 107 are defined on the side surfaces of both the lower housing 100 and the upper housing 101. Mounting blocks 108 are mounted on the outer surfaces of both the first and second sliders 103, 105. The ends of the mounting blocks 108 extend through the first through-slots 107 to the outside and are mounted with blades 109. Clamping blocks 110 are mounted on the side surfaces of both the lower housing 100 and the upper housing 101. A second through slot 111 is defined on the upper surface of the upper housing 101. A push block 112 is disposed within the second through slot 111 and is connected to the second slider 105. A connecting block 113 is mounted on the outer surface of the push block 112. A socket 114 is defined on the lower surface of the connecting block 113. A fixing mechanism 200 is provided on the upper surface of the upper housing 101 that plugs into and engages with the socket 114. A vertical plate 115 is mounted on the outer surface of the vertical plate 115. A turntable 116 is rotatably mounted on the outer surface of the turntable 116. A plurality of positioning blocks 117 are coaxially arrayed on the outer surface of the turntable 116.

[0026] When in use, the second slider 105 is driven to compress the second slider 104 and move it to the side close to the clamping block 110 by toggling the push block 112, and the fixing mechanism 200 is used to fix it. Then, the part of the holmium laser fiber to be peeled is placed between the two blades 109, and the rear part of the holmium laser fiber is placed between the two clamping blocks 110. Then, the upper shell 101 is pressed to drive the two blades 109 to cut the holmium laser fiber, and drive the two clamping blocks 110 to clamp the holmium laser fiber. Then, the push block 112 is released. At this time, the compressed first spring 10 6 pushes the blade 109 to move, so that the peeling operation can be completed. Since the two clamping blocks 110 have a high degree of fit with the outer surface of the holmium laser fiber and always maintain a horizontal state, it can avoid the situation where the internal fiber is easily broken when manually pulled. Finally, use medical tape to stick one end of the holmium laser fiber on the turntable 116, and then rotate the turntable 116 to drive the holmium laser fiber to quickly circle around multiple positioning blocks 117. Then use medical tape to stick the end of the holmium laser fiber on the turntable 116, thereby achieving the purpose of rapid circle.

[0027] Specifically, the fixing mechanism 200 includes a guide rod 201 and an insertion rod 202 that vertically penetrate the interior of the upper shell 101. The bottom of the guide rod 201 and the insertion rod 202 are jointly installed with a connecting plate 203. The top of the guide rod 201 is installed with a pressure block 204. The outer surface of the guide rod 201 is sleeved with a second spring 205. The two ends of the second spring 205 are respectively in contact with the pressure block 204 and the upper shell 101. When the push block 112 is toggled to drive the connecting block 113 to contact and squeeze the insertion rod 202, the insertion rod 202 can be driven by squeezing. 2 contracts downward and compresses the second spring 205. When the insertion hole 114 moves to the top of the insertion rod 202, the compressed second spring 205 releases its elastic force, pushing the pressing block 204 to move upward. Through the connection of the connecting plate 203, the insertion rod 202 can be pushed upward and inserted into the insertion hole 114, thereby fixing the pushing block 112. When the pressing block 204 is pressed downward to remove the insertion rod 202 from the insertion hole 114, the compressed first spring 106 can push the blade 109 to move quickly to complete the peeling.

[0028] Specifically, the first slider 103 and the second slider 105 are connected by a telescopic rod 300. Through the setting of the telescopic rod 300, the first slider 103 can be driven to move synchronously when the second slider 105 is slid. The telescopic rod 300 is telescopic and can provide movement space when the upper shell 101 is pressed downward.

[0029] Specifically, inner grooves 400 are provided at the four corners of the lower surface of the upper shell 101, and a connecting rod 401 is provided inside the inner groove 400 to limit the position, and the end of the connecting rod 401 is connected to the lower shell 100, and a third spring 402 is provided inside the inner groove 400, and the two ends of the third spring 402 are respectively abutted against the connecting rod 401 and the inner wall of the inner groove 400. Through the setting of the inner groove 400 and the connecting rod 401, the lower shell 100 and the upper shell 101 can be connected into a whole, and through the elastic force of the third spring 402, there is always a gap between the lower shell 100 and the upper shell 101, so it is convenient to place the holmium laser fiber between the two blades 109 and the two clamps 110.

[0030] Specifically, a ball 500 is provided on the top of the insertion rod 202. The provision of the ball 500 can reduce frictional resistance and improve smoothness when the connecting block 113 and the insertion rod 202 are squeezed.

[0031] Specifically, a rubber pad is provided on the surface of the clamping block 110, and anti-slip grooves are provided on the outer surface of the rubber pad. The provision of the rubber pad not only improves the protection capability of the holmium laser fiber, but also the rubber pad combined with the anti-slip grooves can increase friction and further improve the clamping effect of the holmium laser fiber.

[0032] The above is a detailed description of the present invention in conjunction with specific embodiments, and the specific implementation methods of the present invention are not limited to these descriptions. For those skilled in the art of the present invention, if a number of equivalent substitutions or obvious modifications are made without departing from the concept of the present invention and have the same performance or use, they should be considered to fall within the scope of patent protection of the present invention as determined by the submitted claims.
