Description

Technical Field

[0001] This invention relates to the field of medical device testing technology, specifically to a laser blade detector capable of detecting laser output. Background Technology

[0002] With the development of science and technology, medical technology has advanced by leaps and bounds. Doctors use laser scalpels to cut patients during surgery. The benefits of using lasers include reducing tissue damage and bleeding at the cutting site, stopping bleeding faster than traditional surgery, and reducing the incidence of wound infection.

[0003] Before surgery, in order to ensure that doctors can better control the laser scalpel, the output laser of the laser scalpel needs to be pre-tested. This is to ensure that the light source output from the scalpel can form a projected spot size at different distances and on the affected area that meets the expected cutting standards. However, the existing laser output testing method usually involves medical staff manually holding the laser scalpel and outputting the laser downwards at different heights to check the size of the projected spot. However, there is no relevant coverage structure set in the spot path, making it difficult for medical staff to know whether the spot size corresponds to the height.

[0004] Furthermore, since medical staff manually hold the laser scalpel to test the laser output, their hands inevitably tremble slightly during the testing process, causing instability in holding the laser scalpel. As the laser scalpel trembles, the output laser will also deviate to some extent, resulting in inaccurate test data, which affects the test results and is not conducive to subsequent use.

[0005] Therefore, in view of this, the present invention proposes a laser blade detector capable of detecting laser output to compensate for and improve the deficiencies of the prior art. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a laser blade detector capable of detecting laser output, thereby resolving the corresponding technical issues raised in the background section.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a laser blade detector capable of detecting laser output, comprising a detection substrate, a positioning circular plate installed at the top center of the detection substrate, and a series of superimposed fixing frames installed on the top of the detection substrate from bottom to top, and a detection aperture adjustment component installed on the fixing frame; an F-shaped vertical frame is mounted on one end of the top of the detection substrate, and a laser blade moving clamping component is installed at the upper end of the F-shaped vertical frame.

[0008] The detection aperture adjustment assembly includes fixed blocks, which are symmetrically and evenly distributed on the inner wall of each side of the fixed frame. Connecting rods are rotatably connected between the fixed blocks on the same side. One end of one of the connecting rods passes through the fixed frame and is connected to a first rotating rod. An arc-shaped plate is installed on the outer ring surface of the connecting rod. The arc-shaped plates unfold to form a circular hole. Connecting heads are installed at both ends of the connecting rod. Adapter plates are rotatably connected to the connecting heads. The adapter plates are all connected by Z-shaped bending plates.

[0009] Furthermore, the circular hole is positioned directly above the positioning circular plate, and the diameter of the circular hole increases sequentially from top to bottom.

[0010] Furthermore, the laser cutter head moving clamping assembly includes a threaded rod, which is rotatably connected to the upper end of the F-shaped vertical frame. A second rotating rod is fixedly connected to one end of the threaded rod that passes through the top of the F-shaped vertical frame. A moving block is threadedly connected to the outer ring surface of the threaded rod. A U-shaped clamping frame is fixedly connected to one side of the moving block, and a U-shaped positioning slide is fixedly connected to the other side of the moving block. The U-shaped positioning slide is slidably connected to the F-shaped vertical frame.

[0011] Furthermore, both ends of the U-shaped clamping frame are slidably connected to slide rods, and each slide rod is fixedly connected to a clamping block at one end facing each other. A second spring is fixedly connected between the clamping block and the U-shaped clamping frame, and the second spring is sleeved on the outside of the slide rod.

[0012] Furthermore, two symmetrically distributed limiting grooves and scale marks are provided on the upper end of one side of the F-shaped vertical frame, and limiting blocks are symmetrically installed on the side of the U-shaped positioning slide away from the moving block, and the limiting blocks are slidably fitted into the inside of the limiting grooves.

[0013] Furthermore, the U-shaped positioning slide has a groove on the inner wall of one side facing the moving block. A push rod is slidably connected inside the groove. A mounting plate is fixedly connected to the end of the push rod away from the groove. A hemisphere is fixedly installed on the side of the mounting plate away from the push rod. A first spring is fixedly connected between the mounting plate and the U-shaped positioning slide, and the first spring is sleeved on the outside of the push rod.

[0014] Furthermore, the upper end of one side of the F-shaped vertical frame is provided with semi-circular grooves at equal intervals, and the semi-circular grooves are adapted to the hemisphere.

[0015] Furthermore, two abutment plates are installed on the outer ring surface of the threaded rod, and the spacing between the abutment plates corresponds to the spacing between the two furthest semicircular grooves.

[0016] Furthermore, the bottom of the U-shaped clamp is symmetrically fixedly connected to two fixing rods, the bottom of which is rotatably connected to a bent rod, and the other end of the bent rod is equipped with a magnet, and the magnets attract each other to form a ring structure.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] (1) By setting up circular holes with progressively larger apertures from top to bottom, it is convenient to match the corresponding path of the light spot mapping during the detection process. Medical personnel can observe from a top-down position whether the light spot gathered on the positioning circular plate is within the range of the circular hole and matches it, so as to determine whether the size of the light spot mapped by the output laser matches the size of the light spot formed at this height.

[0019] (2) During the test, the laser scalpel can be clamped between two clamping blocks. Through the elastic force of the second spring, the clamping blocks and the laser scalpel will form a mutual abutting force to stably clamp the laser scalpel, which will facilitate subsequent movement and testing and avoid changes in the amplitude of the laser output spot, thus affecting the test results.

[0020] (3) After the laser scalpel is clamped and fixed, it can move accordingly on the threaded rod as the moving block moves, and make it engage with the semi-circular groove in sequence. It can also perform laser output detection at that height with the round hole, so that the laser scalpel can perform precise laser output detection at a specific height and avoid height error.

[0021] (4) If rust appears on the blade tip during laser output detection, the rust on the blade tip can be attracted to the magnet by the magnetic force of the set magnet. When the detection work is finished, the medical staff can judge whether the blade tip is rusted based on the rust attracted to the magnet. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Embodiments of the present invention

[0039] Please refer to Figures 1 to 5As shown, it includes a detection substrate 1, a positioning circular plate 2 installed at the top center of the detection substrate 1, and a series of superimposed fixing frames 3 installed on the top of the detection substrate 1 from bottom to top. A detection aperture adjustment component is installed on the fixing frame 3. An F-shaped vertical frame 5 is mounted on one end of the top of the detection substrate 1, and a laser cutter head moving clamping component is installed at the upper end of the F-shaped vertical frame 5.

[0040] Fixed blocks 41 are symmetrically and evenly distributed on the inner wall of each side of the fixed frame 3. Connecting rods 42 are rotatably connected between fixed blocks 41 on the same side. One end of one connecting rod 42 passes through the fixed frame 3 and is connected to a first rotating rod 43. Arc plates 44 are installed on the outer ring surface of the connecting rod 42. Arc plates 44 are unfolded to form circular holes 48. Circular holes 48 are correspondingly set directly above the positioning circular plate 2. The diameter of the circular holes 48 increases from top to bottom. The diameter of the circular holes 48 is always smaller than that of the positioning circular plate 2. Connecting heads 45 are installed at both ends of the connecting rod 42. Adapter plates 46 are rotatably connected to the connecting heads 45. The adapter plates 46 are connected by Z-shaped bending plates 47.

[0041] The effect achieved by this embodiment is as follows: Compared with the prior art, by setting the circular holes 48 with the aperture size increasing from top to bottom, it is convenient to match the corresponding adaptation of the light spot mapping path during the detection process. Medical personnel can observe whether the light spot gathered on the positioning circular plate 2 is within the range of the circular hole 48 and matches it in a top-down position, so as to determine whether the size of the light spot mapped by the output laser is consistent with the size of the light spot formed at this height.

[0042] Please refer to Figure 1 , Figures 6 to 9 As shown, the laser cutter head moving clamping assembly includes a threaded rod 7, which is rotatably connected to the upper end of the F-shaped vertical frame 5. A second rotating rod 6 is fixedly connected to one end of the threaded rod 7 that passes through the top of the F-shaped vertical frame 5. A moving block 91 is threadedly connected to the outer ring surface of the threaded rod 7. A U-shaped clamping frame 92 is fixedly connected to one side of the moving block 91, and a U-shaped positioning slide 93 is fixedly connected to the other side of the moving block 91. The U-shaped positioning slide 93 is slidably connected to the F-shaped vertical frame 5. Slide rods 910 are slidably connected to both ends of the U-shaped clamping frame 92. A clamping block 912 is fixedly connected to one end of each slide rod 910 facing each other. A second spring 911 is fixedly connected between the clamping block 912 and the U-shaped clamping frame 92, and the second spring 911 is sleeved on the outside of the slide rod 910.

[0043] Two symmetrically distributed limiting grooves 11 and scale marks 12 are provided on the upper end of one side of the F-shaped vertical frame 5. Limiting blocks 99 are symmetrically installed on the side of the U-shaped positioning slide away from the moving block 91, and the limiting blocks 99 are slidably fitted into the inside of the limiting grooves 11.

[0044] A groove 94 is provided on the inner wall of the U-shaped positioning slide 93 facing the moving block 91. A push rod 95 is slidably connected inside the groove 94. A mounting plate 97 is fixedly connected to the end of the push rod 95 away from the groove 94. A hemispherical ball 98 is fixedly installed on the side of the mounting plate 97 away from the push rod 95. A first spring 96 is fixedly connected between the mounting plate 97 and the U-shaped positioning slide 93, and the first spring 96 is sleeved on the outside of the push rod 95. A semi-circular groove 10 that matches the hemispherical ball 98 is provided at equal intervals on the upper end of one side of the F-shaped vertical frame 5. The number of semi-circular grooves 10 is one more than the number of circular holes 48. Two abutment plates 8 are installed on the outer ring surface of the threaded rod 7, and the distance between the abutment plates 8 corresponds to the distance between the two farthest semi-circular grooves 10.

[0045] The effects achieved by this embodiment are as follows: In the prior art, the laser scalpel is usually operated manually by medical personnel to output laser at different heights. Due to the influence of human body structure, the laser spot output by the laser scalpel will change in amplitude, affecting the detection effect. Compared with the prior art, during detection, the laser scalpel can be clamped between two clamping blocks 912. Through the elastic force of the second spring 911, a mutual abutting force is formed between the clamping blocks 912 and the laser scalpel, which stably clamps the laser scalpel, facilitates subsequent movement and detection, and avoids the change in amplitude of the laser output spot, which affects the detection effect.

[0046] Furthermore, the manual movement of the laser scalpel by medical personnel is not convenient for controlling the laser scalpel to the specific height required for testing, which may cause deviations from the set height. Compared with existing technologies, this method not only eliminates the need for medical personnel to manually hold the laser scalpel for testing, but also allows the laser scalpel to move along with the moving block 91 after it is clamped and fixed, moving accordingly on the threaded rod 7 and engaging with the semi-circular groove 10 in sequence. This, combined with the circular hole 48, enables precise laser output testing at a specific height, avoiding height errors.

[0047] Please refer to Figure 8 As shown, a fixing rod 913 is symmetrically fixedly connected to the bottom of the U-shaped clamp 92. A bent rod 914 is rotatably connected to the bottom of the fixing rod 913. A magnet 915 is installed at the other end of the bent rod 914, and the magnets 915 attract each other to form a ring structure.

[0048] The effects achieved by this embodiment are as follows: During the use of a laser scalpel, it frequently comes into contact with different liquid components, especially after surgery, when multiple cleanings and disinfections are often required. If the operation and storage are not handled properly, corrosion of the scalpel tip may occur, resulting in instrument damage and unusability. Compared with the prior art, if corrosion occurs at the scalpel tip during laser output detection, the rust on the scalpel tip can be attracted to the magnet 915 by the magnetic force of the magnet. When the detection work is completed, medical personnel can determine whether the scalpel tip is corroded based on the amount of rust attracted to the magnet 915.

[0049] The complete usage steps and working principle of the above embodiments are as follows:

[0050] Before a doctor performs laser cutting surgery on a patient, the laser scalpel tip needs to be inspected to ensure the surgery proceeds smoothly. During the inspection, not only is the appearance of the laser tip checked to prevent damage or rust from going undetected and causing infection, but the light source output by the laser tip also needs to be tested. The light spot projected by the corresponding light source at a specified distance must be kept within a specific size range so that the doctor can accurately control the precision of the laser cutting during subsequent use, ensuring that the cutting surgery can proceed normally and reach its optimal state.

[0051] During testing, the laser scalpel body to be tested is first taken and the lower end of the laser scalpel body is clamped between two clamping blocks 912, so that the blade head is located between two magnets 915. Through the outward squeezing force of the laser scalpel body, the two clamping blocks 912 can be moved in the opposite direction between them, and simultaneously push the slide bar 910 to slide outward on the U-shaped clamping frame 92. Under the elastic force of the second spring 911, a mutual abutting force can be formed between the clamping blocks 912 and the U-shaped clamping frame 92, so that the clamping blocks 912 can clamp the laser scalpel body more stably and firmly.

[0052] After the clamping of the laser scalpel body is completed, the threaded rod 7 can be driven to rotate on the F-shaped vertical frame 5 by rotating the second rotating rod 6. Since the outer ring surface of the threaded rod 7 is threadedly connected to the moving block 91 connected to the U-shaped clamping frame 92, when the threaded rod 7 rotates, the moving block 91 is driven by the thread and will slide upward or downward on the outer ring surface of the threaded rod 7. The upward or downward movement depends on the forward or reverse rotation of the second rotating rod 6. When the moving block 91 slides on the outer ring surface of the threaded rod 7, the laser scalpel body clamped between the two clamping blocks 912 can be moved accordingly through the connection of the U-shaped clamping frame 92, so as to test the size of the light spot formed by the light source output by the laser head at different distances.

[0053] As the moving block 91 moves, driving the U-shaped clamp 92 to move, the U-shaped positioning slide 93 simultaneously slides on the F-shaped vertical frame 5. After being squeezed by the outer wall of the F-shaped vertical frame 5, the hemisphere 98 drives the mounting plate 97 to move towards the moving block 91. At this time, the end of the push rod 95 slides inside the slide groove 94, and the first spring 96 is squeezed by the external force. When the hemisphere 98 approaches the semi-circular groove 10, due to the gap in the groove, the force of the hemisphere 98 being squeezed by the outer wall of the F-shaped vertical frame 5 disappears. At this time, the first spring 96 will rebound, driving the hemisphere 98 to embed into the semi-circular groove 10, realizing the positioning of the moving block 91 on the threaded rod 7. Simultaneously, the detection height of the laser scalpel is always kept in a stopped state so that the size of the laser output spot can be detected at different heights.

[0054] Since the number of semicircular slots 10 on the F-shaped vertical frame 5 is one more than the number of circular holes 48, and a positioning circular plate 2 is set at the bottom of the circular holes 48, the light source reflected by the laser head will eventually stop on the positioning circular plate 2. From top to bottom, it is known that the size of the circular holes 48 increases sequentially. The closer the light source is, the larger the light spot formation range. When the hemisphere 98 is embedded in the first semicircular slot 10, it corresponds to the first circular hole 48. That is, the output light source should be within the coverage of the first circular hole 48 in the top view and be consistent with the size of the circular hole 48. Similarly, when the hemisphere 98 is embedded in the last semicircular slot 10, the output light source should correspond to the coverage of the positioning circular plate 2 in the top view.

[0055] In addition, after the laser output light source has completed the detection of the first circular hole 48 range, when the next circular hole 48 is detected, the unused circular hole 48 can be unfolded. That is, by rotating the first rotating rod 43 on the connecting and fixing frame 3, the connecting rod 42 is driven to rotate, and the arc plate 44 is rotated simultaneously to destroy the formation of the circular hole 48. While the connecting rod 42 is rotating, the remaining connecting rods 42 can be rotated along with it through the rotation connection of the Z-shaped bending plate 47, so that each arc plate 44 can rotate at the same time. This not only destroys the formation of the circular hole 48, but also avoids the problem of the arc plate 44 not being moved and blocking the laser output. At this time, after all the arc plates 44 are unfolded, the corresponding spot size detection of the next circular hole 48 can be performed.

[0056] Finally, as the laser scalpel body moves and detects the output light source, the structure of the laser scalpel head is located between two magnets 915. If there is rust on the head, the rust on the head can be attracted to the magnets 915 by the magnetic force of the magnets 915. When the detection work is over, medical personnel can judge whether the head is rusted based on the rust attracted to the magnets 915.

[0057] The circuits and controls involved in this invention are all existing technologies and will not be described in detail here.

[0058] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
