Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, in particular to a multifunctional corner-turning endoscope laser. BACKGROUND

[0002] Current endoscopic minimally invasive technology has been widely used in the field of clinical medicine, and micro-laryngoscope supported laryngeal lesion resection surgery is also increasing. Carbon dioxide (CO2) laser has the advantages of small surgical trauma, less bleeding, clear surgical field, and can shorten the patient's hospitalization time, speed up recovery, and reduce pain, etc. It shows unique value in the surgical treatment of laryngeal benign lesions and early laryngeal malignant tumors. However, for glottic laryngeal cancer that invades the anterior commissure, the effect of laser surgery treatment is still controversial, and there is a certain recurrence rate after surgery. The related influencing factors are multifaceted, including the lack of cartilage structure in the anterior commissure, the difficulty in judging the depth and range of resection during surgery, and the key problems related to the accuracy of preoperative and intraoperative lesion range determination, as well as the surgeon's experience. The core root of this type of surgery recurrence lies in the incomplete removal of the lesion tissue, which is mainly caused by the multiple disadvantages related to the surgical field. On the one hand, the microscope field is obviously limited, and the light cannot be turned, combined with the small space of the laryngeal cavity, which easily causes visual obstruction and poor exposure of the surgical site, making it difficult for the surgeon to clearly observe the whole picture of the lesion. On the other hand, the small space of the laryngeal cavity also easily causes the problem of mutual interference and "fighting" of the operating instruments. Although the use of CO2 laser can save part of the operating space, it has the inherent defect of being unable to turn, which directly leads to limited surgical resection range and further affects the resection effect.

[0003] In view of the above technical problems, the present application provides a multifunctional corner-turning endoscope laser. SUMMARY

[0019] 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.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Reference Figs. 1-3 This invention provides a multifunctional rotatable endoscope laser, comprising: Adjustable bracket 1, on which mounting base 2 and linear adjustment assembly are mounted; The mounting bracket is rotatably connected to the linear adjustment component via the angle adjustment component; The instrument handle 3 is detachably connected to the mounting frame. The instrument handle 3 is provided with a laser inlet 4, an instrument inlet 5, and no less than two sets of auxiliary operation ports 6. Snake bone 7 is mounted on instrument handle 3. An operating component is mounted on instrument handle 3. The operating component is used to control the bending of snake bone 7. Several sets of channels are opened on snake bone 7. The channels are respectively connected to laser inlet 4, instrument inlet 5 and auxiliary operating port 6. Laser emitter 8 is fixed on mounting base 2. Laser emitter 8 transmits laser light through optical fiber through laser inlet 4 and out through the end of snake bone 7. The image acquisition system has its probe part entering the end of the snake bone 7 through the auxiliary operation port 6 and the channel; The control system is used to control the operation of the overall device.

[0022] When the device is in operation, first adjust the height and horizontal position of the mounting frame using the linear adjustment component on the adjustable bracket 1. Then, rotate the mounting frame using the angle adjustment component to bring the instrument handle 3 to the appropriate operating angle. Next, detachably mount the instrument handle 3 onto the mounting frame, ensuring a secure connection. Then, connect the laser emitter 8 to the laser inlet 4 of the instrument handle 3 via an optical fiber. Insert the probe of the image acquisition system into the end of the snake bone 7 through the auxiliary operating port 6 and the corresponding channel on the snake bone 7. Simultaneously, according to operational requirements, insert the diagnostic and treatment instruments into the channel of the snake bone 7 through the instrument inlet 5. Control the bending of the snake bone 7 using the operating component on the instrument handle 3 to adjust the orientation of the snake bone 7's end, ensuring the image acquisition system probe is precisely aligned with the treatment area, acquiring images of the area in real time and feeding them back to the control system. The control system coordinates and regulates the operation of the entire device. It starts the laser emitter 8, and the laser is led out from the end through the optical fiber, laser inlet 4, and snake bone 7 channel to perform laser treatment on the target area. At the same time, it can cooperate with the instrument to perform auxiliary diagnosis and treatment operations through the auxiliary operation port 6 and instrument inlet 5. Throughout the process, the position and angle of the instrument can be finely adjusted through the linear adjustment component and the angle adjustment component to ensure that the diagnosis and treatment operation is completed accurately and efficiently.

[0023] The scheme is further optimized. The linear adjustment component includes a lead screw and a slider. The slider is slidably connected to the adjustable bracket 1, and the lead screw is rotatably connected to the adjustable bracket 1. The lead screw passes through the slider and is threadedly connected to the slider. A handle is installed at one end of the lead screw.

[0024] During operation, the operator rotates the handle at one end of the lead screw, and through the threaded transmission, the rotational motion of the handle is converted into the linear motion of the slider. This, in turn, drives the mounting bracket and instrument handle 3 connected to the slider to move linearly up or down or horizontally in sync, so as to achieve precise linear adjustment of the instrument position and meet the height and horizontal position requirements in different diagnosis and treatment scenarios.

[0025] A dustproof sealing ring is installed at the connection between the lead screw and the adjustable bracket 1 to prevent bodily fluids, dust, etc. generated during the diagnosis and treatment process from entering the thread gap between the lead screw and the slider, avoiding thread wear and jamming, and extending the service life of the components; a travel limit switch is added to the slider to clearly define the maximum travel of the slider and prevent the slider from sliding excessively due to operational errors, which could damage the lead screw, bracket, or other related components; anti-slip texture and scale markings are added to the handle to improve the operating feel and facilitate the operator to accurately control the movement distance of the slider, further improving the adjustment accuracy.

[0026] The design is further optimized. The mounting frame includes a mounting plate 9, which is mounted on the slider. Side plates 10 are symmetrically mounted on the mounting plate 9. A deflection frame 11 is mounted on the side plate 10. A connecting seat 12 is mounted on the deflection frame 11. The operating handle is detachably connected to the connecting seat 12.

[0027] Mounting plate 9 is fixedly mounted on the slider of the linear adjustment assembly, providing the mounting base for the entire mounting frame. Symmetrical side plates 10 are symmetrically fixed on mounting plate 9 for mounting deflection frame 11. Deflection frame 11 is assembled on side plate 10, and connecting seat 12 is fixed on deflection frame 11. Instrument handle 3 is detachably connected to connecting seat 12 via a quick-release structure. Through the fixed connection between mounting plate 9 and slider, the movement of the linear adjustment assembly is supported. The angle of connecting seat 12 is adjusted by deflection frame 11, thereby driving instrument handle 3 to adjust its posture. At the same time, connecting seat 12 provides stable mounting support for instrument handle 3, ensuring that instrument handle 3 does not loosen during operation.

[0028] A reinforcing rib is added at the connection between the mounting plate 9 and the slider to improve the load-bearing capacity of the mounting plate 9, prevent deformation of the mounting plate 9 after long-term use, and ensure the stability of the mounting frame. Wear-resistant grease is applied to the connection between the side plate 10 and the deflection frame 11 to reduce friction between the sliding shaft and the arc groove, and between the deflection frame 11 and the side plate 10, thereby reducing operating resistance and reducing component wear. A positioning pin is added to the connecting seat 12 to cooperate with the positioning hole at the bottom of the instrument handle 3, further improving the coaxiality and stability of the instrument handle 3 after installation and preventing deviation during operation.

[0029] The scheme is further optimized. The deflection frame 11 includes a rectangular deformation frame and a sliding frame. An arc-shaped groove is provided on the side plate 10. The sliding frame is slidably connected in the arc-shaped groove through a sliding shaft. A positioning nut is installed on the sliding shaft and abuts against the side plate 10.

[0030] During operation, the sliding frame is pushed to drive the sliding shaft to slide along the arc groove of the side plate 10. The rectangular deformation frame deflects synchronously with the sliding shaft, thereby driving the connecting seat 12 and the instrument handle 3 to adjust the angle around the arc groove trajectory. After adjusting to the appropriate angle, the positioning nut is tightened. The friction force generated by the clamping force between the positioning nut and the side plate 10 fixes the position of the sliding shaft, thereby locking the angle of the deflection frame 11 and ensuring that the instrument handle 3 maintains a stable posture during diagnosis and treatment.

[0031] Further optimization of the scheme: the angle adjustment component includes an inverted frame, which is rotatably connected to the slider. The mounting plate 9 is fixed to the frame, and an adjustment motor is fixedly connected to the slider. The output shaft of the adjustment motor is shaft-connected to the rotating shaft of the frame.

[0032] The control system issues a command to start the adjustment motor. The output shaft of the adjustment motor drives the C-shaped frame to rotate around its rotation axis with that of the slider. The frame then drives the mounting plate 9, the mounting bracket and the instrument handle 3 to rotate synchronously, realizing the electric precise adjustment of the angle of the instrument handle 3. Compared with manual adjustment, it improves the accuracy and convenience of angle adjustment and adapts to the needs of refined diagnosis and treatment.

[0033] The scheme has been further optimized. The operating components include a dial, a traction wire, and a reset component. One end of the traction wire is connected to the dial, and the other end passes through the instrument handle 3 and is connected to the snake bone 7. The reset component is used to reset the snake bone 7 after it is bent.

[0034] One end of the traction wire is connected to the dial wheel, and the other end passes through the inside of the instrument handle 3 and connects to the end of the snake bone 7. A reset component (such as a spring) is assembled at the connection between the snake bone 7 and the instrument handle 3 to reset the snake bone 7 after bending. During operation, the operator rotates the dial wheel on the instrument handle 3, which drives the traction wire to pull the corresponding part of the snake bone 7, causing the snake bone 7 to bend in the traction direction, thereby adjusting the orientation of the end of the snake bone 7 and achieving precise positioning of the endoscopic field of view and the laser exit. When the dial wheel is released, the reset component generates a reverse force, pulling the snake bone 7 back to its initial straight state, facilitating adjustments to the operation or ending the treatment.

[0035] The design is further optimized by providing a quick-release structure between the instrument handle 3 and the mounting bracket. The quick-release structure includes a buckle, a slot, and a locking element. The buckle and the slot engage with each other, and the locking element is used to fix the relative position of the instrument handle 3 and the mounting bracket.

[0036] When installing the instrument handle 3, snap the buckle into the corresponding slot to achieve quick positioning and docking of the instrument handle 3 and the connecting seat 12; then tighten the locking piece to further fix the relative position of the two and prevent loosening during diagnosis and treatment; when disassembling, loosen the locking piece and press the buckle to quickly separate the instrument handle 3 from the mounting bracket, which facilitates the cleaning, disinfection and replacement of the instrument handle 3.

[0037] The scheme was further optimized by connecting the image acquisition system and the control system. The control system is used to receive and display the endoscopic field-of-view images acquired by the image acquisition system.

[0038] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.
