Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and specifically relates to an alignment device, particularly a device for aligning the laser head of a laser vibrometer with the ultrasonic scalpel treatment head. Background Technology

[0002] The principal amplitude and transverse amplitude of the ultrasonic scalpel tip are important performance indicators for evaluating the performance of ultrasonic soft tissue cutting and hemostasis surgical tips. Currently, most methods use laser vibrometers to measure these amplitudes. Laser vibrometers require a sufficiently small output beam spot size to focus on the tip of the ultrasonic scalpel treatment head, and the beam should be parallel to the longitudinal axis of the tip vibration, i.e., aligned with the direction of the measured tip amplitude. However, common scalpel tips have a certain curvature, which makes it difficult for the laser head of the vibrometer to align the laser with the treatment head. Utility Model Content

[0003] To address the aforementioned problems, the primary objective of this invention is to provide an alignment device that solves the technical problem of long alignment time between the laser head indicating laser and the ultrasonic scalpel treatment head in current laser vibrometers.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] This utility model provides an alignment device, comprising:

[0006] The rotating mechanism is used to move the light spot generated by the laser head along any one of the first, second, or third directions, and to rotate the light spot in a plane so that the light spot is aligned with the cutting head.

[0007] The rotating mechanism drives the laser head to move the light spot along any of the first, second, or third directions, and rotates the light spot within the same plane to achieve alignment between the laser head's light spot and the tip of the cutting tool. This simple operation facilitates rapid alignment, saves time, and improves testing efficiency.

[0008] Furthermore, the rotating mechanism includes:

[0009] platform;

[0010] A slide, mounted on the platform, is used to mount the laser head on the side furthest from the platform; wherein,

[0011] The platform is used to move the slide table along any one of the first direction, the second direction, and the third direction;

[0012] The slide is used to rotate the light spot in the plane so that the light spot is aligned with the cutter head.

[0013] The laser head is mounted on the side of the slide away from the platform. The platform drives the slide to move along any of the first, second, or third directions, and the slide drives the laser head's spot to rotate 360° in the same plane, thereby aligning the laser head's spot with the cutting head.

[0014] Furthermore, the rotating mechanism also includes:

[0015] A gimbal is positioned on the side of the slide away from the platform and is used to clamp the laser head so that the laser head rotates synchronously with the slide.

[0016] The gimbal is positioned on the side of the slide away from the platform, and the gimbal clamps and fixes the laser head. Since the slide and the gimbal rotate synchronously, the gimbal and the laser head rotate synchronously, thus the laser head and the slide rotate synchronously.

[0017] Furthermore, the rotating mechanism also includes:

[0018] A first axis assembly is connected to the platform and is used to drive the platform to move the laser head along the first direction;

[0019] The second axis assembly is connected to the platform and is used to drive the platform to move the laser head along the second direction;

[0020] The third axis assembly, connected to the platform, is used to drive the platform to move the laser head along the third direction;

[0021] Wherein, any two of the first axis assembly, the second axis assembly, and the third axis assembly are perpendicular to each other.

[0022] By designing the first axis assembly, the second axis assembly, and the third axis assembly, the movement of the platform along the first, second, and third directions can be adjusted arbitrarily, enabling the laser head's spot to be irradiated onto the same horizontal plane of the cutter head's end face.

[0023] Furthermore, the adjustable stroke of the first shaft assembly is -12.5mm to 12.5mm; and / or,

[0024] The adjustable stroke of the second shaft assembly is -12.5mm to 12.5mm; and / or,

[0025] The adjustable stroke of the third axis assembly is 20 mm.

[0026] Furthermore, the slide is an R-axis rotary slide, and the slide includes:

[0027] A micrometer head is connected to the slide table and is used to drive the slide table to rotate;

[0028] A switching screw is connected to the micrometer head micrometer to adjust the angle at which the micrometer head micrometer drives the slide to rotate.

[0029] Furthermore, the switching screw adjusts the micrometer head micrometer by a step rotation angle of 0.84'.

[0030] By switching the coarse / fine adjustment screw, the micrometer head can be stepped and adjusted. The micrometer head can then adjust the rotation angle of the slide, changing the horizontal position of the laser head spot on the slide. This allows the laser spot to rotate in the same plane, aligning it with the cutting head. Once aligned, amplitude testing can be performed.

[0031] Furthermore, the rotating mechanism also includes:

[0032] The coarse adjustment push rod is connected to the slide table and is used to adjust the rotation angle of the slide table.

[0033] By adjusting the rotation angle of the coarse adjustment slide by adjusting the coarse adjustment push rod, the horizontal position of the laser head spot on the slide can be changed, so that the spot can rotate in the same plane and achieve alignment between the spot and the cutter head.

[0034] Furthermore, the slide table and the platform are connected by screws; the slide table and the platform are connected by M4 screws.

[0035] By fixing the slide table to the platform, the platform drives the slide table to move synchronously along the first direction, the second direction, and the third direction, which enables the laser head's spot to be irradiated onto the same horizontal plane of the cutter head's end face.

[0036] Furthermore, the gimbal and the slide are connected by screws; the gimbal is locked to the slide by M4 screws, and the gimbal is used to clamp and fix the laser head, the position of the laser head changes as the slide rotates.

[0037] Compared with the prior art, the beneficial effects of this application are as follows: The alignment device includes a rotating mechanism for moving the light spot generated by the laser head along any one of the first, second, or third directions, and for rotating the light spot until the light spot is aligned with the blade tip. Through the coarse / fine adjustment rotating mechanism, the light spot generated by the laser head is moved along any one of the first, second, or third directions, and the light spot is rotated and adjusted to achieve alignment between the laser head's light spot and the blade tip. This method is simple to operate, facilitates rapid alignment, saves time, and improves testing efficiency. Attached Figure Description

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0042] To achieve the above objectives, the technical solution of this utility model is as follows:

[0043] See Figures 1-2 This utility model provides an alignment device, particularly a device for aligning the laser head of a vibration meter with the tip of the blade of an ultrasonic soft tissue cutting and hemostasis surgical device. Specifically, the alignment device is used to align the light spot generated by the laser head 1 with the tip 3 of the blade 2. The alignment device includes a rotating mechanism 10, which is used to drive the light spot generated by the laser head 1 to move along any one of the first direction, the second direction, or the third direction, and to drive the light spot to rotate in a plane until the light spot is aligned with the blade 2.

[0044] The rotating mechanism 10 drives the light spot generated by the laser head 1 to move along any of the first, second, or third directions, and drives the light spot to rotate and adjust in the same plane, so that the light spot of the laser head 1 is aligned with the tip 3 of the cutter head 2. The operation is simple, facilitates rapid alignment, saves time, and improves testing efficiency.

[0045] Furthermore, the rotating mechanism 10 includes: a platform 100; a slide 200 disposed on the platform 100, with the side away from the platform 100 used to load the laser head 1; wherein, the platform 100 is used to drive the slide 200 to move along any one of the first direction, the second direction, and the third direction; the slide 200 is used to drive the light spot to rotate in the plane so that the light spot is aligned with the cutter head 2.

[0046] The laser head 1 is mounted on the side of the slide table 200 away from the platform 100. The platform 100 drives the slide table 200 to move along any one of the first, second, or third directions, and the slide table 200 drives the laser spot of the laser head 1 to rotate 360° in the same plane, thereby aligning the laser spot of the laser head 1 with the cutter head 2.

[0047] Preferably, the first direction is the X-axis, the second direction is the Y-axis, and the third direction is the Z-axis.

[0048] This alignment device, during use, adjusts the left-right position of the laser head 1 by adjusting the first axis assembly 110 (X-axis), adjusts the front-back position of the laser head 1 by adjusting the Y-axis, and adjusts the vertical position of the laser head 1 by adjusting the Z-axis, thereby changing the position of the laser spot. Therefore, by using the platform 100, first axis assembly 110, second axis assembly 120, and third axis assembly 130 of this alignment device, vertical, left-right, and front-back position adjustments can be achieved.

[0049] Furthermore, the rotating mechanism 10 also includes a gimbal 300, which is located on the side of the slide table 200 away from the platform 100, for clamping the laser head 1 so that the laser head 1 rotates synchronously with the slide table 200.

[0050] The gimbal 300 is positioned on the side of the slide 200 away from the platform 100. The gimbal 300 clamps and fixes the laser head 1. Since the slide 200 and the gimbal 300 rotate synchronously, the gimbal 300 and the laser head 1 rotate synchronously, thus the laser head 1 and the slide 200 rotate synchronously.

[0051] Furthermore, the rotating mechanism 10 also includes: a first axis assembly 110 connected to the platform 100 for driving the platform 100 to move the laser head 1 along a first direction; a second axis assembly 120 connected to the platform 100 for driving the platform 100 to move the laser head 1 along a second direction; and a third axis assembly 130 connected to the platform 100 for driving the platform 100 to move the laser head 1 along a third direction; wherein any two of the first axis assembly 110, the second axis assembly 120, and the third axis assembly 130 are perpendicular to each other.

[0052] Through the design of the first axis assembly 110, the second axis assembly 120 and the third axis assembly 130, the platform 100 can be adjusted to move along the first direction, the second direction and the third direction, so as to irradiate the laser spot of the laser head 1 onto the same horizontal plane of the end face of the cutter head 2.

[0053] Furthermore, the adjustable stroke of the first axis assembly 110 is -12.5mm to 12.5mm; and / or, the adjustable stroke of the second axis assembly 120 is -12.5mm to 12.5mm; and / or, the adjustable stroke of the third axis assembly 130 is 20mm.

[0054] To accommodate treatment heads from different manufacturers, the alignment device must be adjustable in left-right, front-back, up-down, and 360° angles to ensure the laser head 1 and the blade head 2 are aligned in a straight line. Through these three dimensions, specifically the adjustable stroke range design of the first axis assembly 110, the second axis assembly 120, and the third axis assembly 130, the platform 100 can, within a preset size range, irradiate the laser spot of the laser head 1 onto the same horizontal plane of the end face of the blade head 2.

[0055] Furthermore, the slide 200 is an R-axis rotary slide, preferably one of RS60, RS80, RS90, RS100, and RS125, and more preferably, the R-axis rotary slide is RS125-L with a step angle of 0.84'. The R-axis rotary slide also includes a micrometer head 210, a switching screw 220, and a locking screw 240. The R-axis rotary slide can achieve adjustment of any angle within a 360° range.

[0056] It should be noted that the micrometer head 210 is used to drive the slide table 200 to rotate. The switching screw 220 is specifically a coarse / fine adjustment switching screw. The switching screw 220 is connected to the slide table 200 and is used to adjust the micrometer head 210 in steps. The micrometer head 210 is used to adjust the rotation angle of the slide table 200, which can change the horizontal position of the laser spot 1 on the slide table 200, so that the laser spot can rotate in the same plane to achieve alignment between the laser spot and the cutter head 2. After alignment, amplitude testing can be performed.

[0057] Furthermore, the switching screw 220 connects to the micrometer head 210, and the step angle for adjusting the micrometer head 210 is 0.84'. That is, by switching the screw 220, the micrometer head 210 can be finely adjusted within a small range, with an angle adjustment step of 0.84'.

[0058] Furthermore, the locking screw 240 is used to lock the micrometer head 210. After rotating the table surface of the slide 200 to a specific position and tightening the locking screw 240, the micrometer head 210 can be used for further fine-tuning.

[0059] Furthermore, the rotating mechanism 10 also includes a coarse adjustment push rod 230, which is fixedly connected to the slide 200 and used to coarsely adjust the rotation angle of the slide 200. The coarse adjustment push rod 230 is used to perform 360° coarse adjustment on the slide 200. Thus, by adjusting the rotation angle of the slide 200 by adjusting the coarse adjustment push rod 230, a large-range 360° angle coarse adjustment can be achieved. This can change the horizontal position of the laser spot 1 on the slide 200, so that the laser spot can rotate 360 ​​degrees in the same plane to achieve alignment between the laser spot and the cutter head 2. After alignment, amplitude testing can be performed.

[0060] The coarse adjustment lever 230 allows for a wide 360° range of angle adjustment, while the micrometer head 210 allows for fine adjustment within a small range by adjusting the switching screw 220, with a step angle of 0.84'. Rotating the slide 200 aligns the light spot with the curved portion of the cutter head 2. Thus, by manually rotating the slide 200, 360° rotation within the same plane can be achieved through coarse and fine adjustments, allowing for arbitrary angle adjustment and ultimately aligning the light spot with the cutter head 2. This changes the horizontal position of the light spot, enabling amplitude testing after alignment.

[0061] Furthermore, the slide 200 is securely connected to the platform 100. The slide 200 and the platform 100 are connected by M4 screws.

[0062] By fixing the slide table 200 and the platform 100 together as a whole, the platform 100 drives the slide table 200 to move synchronously along the first direction, the second direction and the third direction, so that the light spot of the laser head 1 can be irradiated on the same horizontal plane of the end face of the cutter head 2.

[0063] Furthermore, the gimbal 300 is securely connected to the slide 200. The gimbal 300 is locked to the slide 200 with M4 screws. The gimbal 300 is used to clamp and fix the laser head 1, and the position of the laser head 1 changes as the slide 200 rotates. The function of the gimbal 300 is to connect and fix the laser head 1 to the platform 100, and to change the position of the laser head 1, i.e., change the position of the light spot, by changing the position of the platform 100. Through the gimbal 300, the laser head 1 of the vibration meter is fixed to the slide 200, and the position of the laser head 1 is changed by adjusting the slide 200.

[0064] The alignment device, through a rotating mechanism 10, moves the light spot generated by the laser head 1 along any of the first, second, or third directions, and rotates the light spot within a plane until the light spot is aligned with the blade head 2. The coarse / fine adjustment rotating mechanism 10 moves the light spot generated by the laser head 1 along any of the first, second, or third directions, and rotates the light spot within the same plane to achieve alignment between the light spot of the laser head 1 and the tip 3 of the blade head 2.

[0065] Therefore, by manually adjusting the three-dimensional movable platform 100, the slide 200, and the gimbal 300, the first axis assembly 110 is used to adjust the laser head 1 forward and backward during operation, the second axis assembly 120 is used to adjust the laser head 1 left and right, and the third axis assembly 130 is used to adjust the laser head 1 up and down; the slide 200 can be adjusted at any angle within the same horizontal plane; and the gimbal 300 can clamp and fix the laser head 1 to the slide 200.

[0066] This alignment device, with the laser head 1 of the vibration meter aligned with the tip 3 of the blade 2 of the ultrasonic soft tissue cutting and hemostasis surgical device, has the following function when detecting the amplitude of the blade 2 of the ultrasonic soft tissue cutting and hemostasis surgical device:

[0067] 1. Using a three-dimensional adjustable platform 100 and slide 200, the three-axis displacement adjustment of the first axis assembly 110, the second axis assembly 120 and the third axis assembly 130 and the 360° rotation adjustment of the slide 200 in the same plane can adapt to the alignment of cutter heads and light spots of different brands, models and specifications, and then perform cutter head amplitude testing.

[0068] 2. It can greatly reduce alignment time. If a tripod is used for adjustment, it is inconvenient to realize three-dimensional and angle adjustment, and fine adjustment cannot be made, which greatly increases the alignment time. Using this alignment device, the alignment time is reduced by at least two-thirds compared to before. It is simple and convenient to operate and can greatly improve testing efficiency.

[0069] After aligning the laser spot of laser head 1 with the tip 3 of blade head 2 using the alignment device, the equipment is started to complete the amplitude detection. The steps are as follows:

[0070] The laser head 1 of the vibration meter is locked on the slide table 200 via the gimbal 300. At this time, the vibration meter is turned on and the laser head 1 emits a light spot, which is used as an indicator light spot. The cutter head 2 is placed at a distance of more than 30cm from the laser head 1.

[0071] By adjusting the first axis assembly 110, the second axis assembly 120, and the third axis assembly 130 of the platform 100, the light spot of the laser head 1 is aligned with the tip 3 of the blade head 2 to be tested on the same horizontal plane. Since the end face of the blade head 2 is often a curved tip, the angle alignment can be achieved by coarse or fine adjustment of the slide table 200, so that the light spot hits the center position of the tip 3 of the blade head 2, thus completing the alignment before the test.

[0072] In summary, the alignment device of this utility model is highly versatile. Differences in the shape of blades from different manufacturers can be eliminated by adjusting the alignment device to align the laser head 1 with the tip 3 of the blade head 2, greatly saving alignment time and significantly improving detection efficiency.

[0073] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
