Description

Technical Field

[0001] The invention relates to the field of hepatobiliary surgery, and in particular to a surgical magnifying glass for hepatobiliary surgery. Background Art

[0002] Surgical loupes play a vital role in hepatobiliary surgery. They use advanced optical stereoscopic observation technology to focus the observer's binocular vision on the surgical area, thus providing a bright and magnified three-dimensional field of view. This technology not only helps surgeons observe surgical details more clearly, but also improves the accuracy and safety of the surgery.

[0003] The surgical magnifier used in hepatobiliary surgery in the prior art usually consists of an eyepiece, a magnifying lens and an objective lens with fixed focal lengths, which can effectively magnify the patient's internal conditions, thereby facilitating the doctor to perform the operation. However, the surgical magnifier used in hepatobiliary surgery in the prior art usually has a fixed position of the eyepiece, the magnifying lens and the objective lens, which makes it difficult to adjust the observation magnification, making it difficult for the doctor to accurately observe the patient's internal conditions, thereby affecting the doctor's operation; if adjustment is required, the eyepiece, the magnifying lens and the objective lens need to be replaced, which affects the efficiency of the operation.

[0004] Therefore, the present invention proposes a surgical magnifying glass for hepatobiliary surgery. Through the design of the magnifying component, it is convenient for doctors to quickly adjust different magnifications, and it is convenient for doctors to observe the patient's internal conditions, so as to better perform the operation. Summary of the invention

[0005] To solve the above problems, the present invention proposes a surgical magnifying glass for hepatobiliary surgery. Through the design of the magnifying component, it is convenient for doctors to quickly adjust different magnifications and observe the patient's internal conditions, so as to better perform the operation; and such a design is more suitable for the surgical environment, thereby making the operation more efficient.

[0006] In order to achieve the above-mentioned object, the technical scheme of the present invention is as follows: a surgical magnifying glass for hepatobiliary surgery, comprising a mesh helmet, a support component for supporting and adjusting the angle is provided on the top of the mesh helmet, and magnifying components for magnified observation are symmetrically provided on both sides of the bottom of the support component;

[0007] The amplification component includes an adjustment box, the inner wall of the adjustment box is fixedly connected to an electric control cylinder, the electric control cylinder is electrically connected to a controller, and the controller is used to control the operation of the electric control cylinder; an arc plate is coaxially fixedly connected to the output shaft of the electric control cylinder; a center rod is fixedly connected to the inner wall of the adjustment box away from the electric control cylinder, a plurality of rotating blocks are sleeved on the center rod and the rotating blocks are all rotatably matched with the center rod, the inner walls of the rotating blocks are fixedly connected to guide blocks, and the tops of the rotating blocks are fixedly connected to magnifying lenses;

[0008] The central rod is provided with a sliding groove for the arc plate to slide, and the arc plate is provided with an arc groove for the guide block to slide; a plurality of rotating grooves are provided on the side of the adjustment box close to the magnifying lens, and the magnifying lens and the rotating block are respectively rotatably matched with the adjacent rotating grooves.

[0009] The technical principles of the above scheme are as follows:

[0010] The doctor puts the mesh helmet on his head and controls the support assembly through the controller to rotate the adjustment box to an angle that is convenient for observation. After the angle adjustment is completed, the doctor starts the electric cylinder through the controller, the output shaft of the electric cylinder extends, and the arc plate slides forward on the sliding groove; when the arc groove contacts the guide block, the guide block rotates according to the trajectory of the arc groove; the guide block then drives the rotating block to start rotating on the support rod, and the rotating block drives the zoom lens to rotate through the rotating groove to align with the observation point, and the zoom lens magnifies the observation point. When the output shaft of the electric cylinder drives the arc plate to contract, the arc groove will cause the guide block to rotate in the opposite direction, and the guide block drives the rotating block to return to its original position.

[0011] The above scheme has the following beneficial effects:

[0012] 1. The present invention uses the design of the electric control cylinder and the arc plate, so that the doctor can easily adjust the position of the magnifying lens through the controller, thereby realizing the rapid change of the observation magnification. This design avoids the cumbersome process of replacing the eyepiece, magnifying lens and objective lens in traditional surgery, greatly improving the efficiency of surgery. Since the magnification can be adjusted quickly, the doctor can observe the patient's internal conditions more accurately, reducing the risk of surgery, improving the safety of surgery, and thus greatly improving the quality of surgery.

[0013] 2. The design of several rotating blocks and magnification mirrors of the present invention makes the device more adaptable to different surgical environments and surgical needs. Doctors can quickly adjust the observation angle and magnification according to actual conditions to adapt to different surgical sites and surgical steps.

[0014] 3. The design of the mesh helmet of the present invention enables the doctor to maintain a comfortable head posture during the operation, reduces the fatigue caused by long-term surgery, and improves the operation efficiency and the doctor's concentration.

[0015] Furthermore, an observation box is fixedly connected to one side of the adjustment box with a rotating groove, an eyepiece is embedded in the side of the observation box close to the mesh helmet, and an objective lens is embedded in the side of the observation box away from the mesh helmet, and the center point of the objective lens and the center point of the eyepiece are located on the same center line.

[0016] Beneficial effect: When the magnifying lens rotates through the rotating slot and enters the observation box to align with the observation point, the doctor can clearly observe the situation inside the patient's body through the eyepiece, the magnifying lens and the objective lens.

[0017] Furthermore, the support assembly includes a support rod, which is laterally fixedly connected to the top of the net helmet, a first motor is fixedly connected to the side of the support rod away from the net helmet, an adjusting rod is fixedly connected to the output shaft of the first motor, a second motor is fixedly connected to the bottom of the adjusting rod, the output shaft of the second motor is fixedly connected to a center frame, and both ends of the center frame are fixedly connected to the side of the observation box away from the adjusting box; the controller is used to control the opening and closing of the first motor and the second motor.

[0018] Beneficial effect: The doctor can control the first motor and the second motor through the controller to align the eyepiece with the eyes according to the height of the doctor's eyes, so as to better observe the situation inside the patient's body.

[0019] Furthermore, a temperature regulator is fixedly connected to the inner wall of the regulating box.

[0020] Beneficial effects: During surgery, the lens of the surgical magnifier may be fogged due to factors such as the temperature difference between the operating room and outside, the irradiation of the surgical light, and the heat of the doctor's head, thus affecting the clarity of the surgical field of view. The existence of the temperature regulator can effectively control the temperature in the regulating box, avoid the lens from fogging due to excessive temperature difference, and ensure that the doctor can clearly observe the surgical site during surgery.

[0021] Furthermore, a plurality of tilting rods are fixedly connected between the support rod and the net helmet.

[0022] Beneficial effect: The presence of the tilt rod enables a more firm and stable connection between the support rod and the mesh helmet, thereby improving the overall stability of the device and enabling doctors to perform surgery better.

[0023] Furthermore, corresponding interface ropes are fixedly connected to both sides of the bottom of the net helmet.

[0024] Beneficial effect: After the doctor puts the mesh helmet on the head, the interface ropes on both sides of the face are connected to the lower jaw accordingly, making the entire device more stable, so that the doctor can perform the operation better.

[0025] Furthermore, a camera is fixedly connected to the side of the center frame away from the net helmet, and the controller is used to control the operation of the camera.

[0026] Beneficial effects: The camera can record the entire surgical process, which is used for post-operative analysis, teaching, and resolution of medical disputes. At the same time, the images of the surgical process can be transmitted in real time, which facilitates real-time consultation between doctors and other medical teams, thereby improving the quality of surgery.

[0027] Furthermore, both sides of the rotating groove close to the rotating block are fixedly connected with limit blocks.

[0028] Beneficial effect: When the rotating block rotates, the limit block can prevent the position of the rotating block from shifting, allowing the zoom lens to stably enter the rotating groove, thereby enabling the zoom lens to stably achieve the magnification function.

[0029] Furthermore, magnetic plates are fixedly connected to both sides of the rotating block close to the limiting block, and the limiting block is made of metal.

[0030] Beneficial effect: When the rotating block is stationary, the magnetic plate and the limit block will be attracted to each other, so that the rotating block remains fixed and prevents the rotating block from rotating, thereby providing a good premise for the subsequent arc plate to use the arc groove to drive the rotating block to rotate; and the shear force generated by the arc groove on the guide block is greater than the adsorption force of the magnetic plate on the limit block.

[0031] Furthermore, a plurality of LED lamps are fixedly connected to a side of the central frame away from the net helmet, and a controller is used to control the operation of the LED lamps.

[0032] Beneficial effects: During surgery, LED lights can provide sufficient and uniform lighting for the surgical area, allowing doctors to observe the surgical site more clearly, thereby improving the success rate and safety of the surgery.

[0033] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following is further described in detail through specific implementation methods:

[0041] Embodiment 1:

[0042] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 Shown is a surgical magnifying glass for hepatobiliary surgery, comprising a mesh helmet 1, a support component for supporting and adjusting the angle is provided on the top of the mesh helmet 1, and magnifying components for magnified observation are symmetrically provided on both sides of the bottom of the support component.

[0043] The amplification component includes an adjustment box 4, the inner wall of the adjustment box 4 is bolted and fixedly connected to an electric control cylinder 10, the electric control cylinder 10 is electrically connected to a controller, and the controller is used to control the operation of the electric control cylinder 10; the output shaft of the electric control cylinder 10 is bolted and coaxially fixedly connected to an arc plate 11; the inner wall of the adjustment box 4 away from the electric control cylinder 10 is bolted and fixedly connected to a center rod 12, a plurality of rotating blocks 13 are sleeved on the center rod 12 and the rotating blocks 13 are all rotatably matched with the center rod 12, the inner walls of the rotating blocks 13 are fixedly bonded with guide blocks 17, and the tops of the rotating blocks 13 are fixedly bonded with magnifying lenses 14.

[0044] The center rod 12 is provided with a sliding groove for the arc plate 11 to slide, and the arc plate 11 is provided with an arc groove for the guide block 17 to slide; the adjustment box 4 is provided with a plurality of rotating grooves 16 on the side close to the magnifying lens 14, and the magnifying lens 14 and the rotating block 13 are respectively rotatably matched with adjacent rotating grooves 16.

[0045] An observation box 5 is integrally formed on one side of the adjustment box 4 close to the rotating groove 16, an eyepiece 9 is embedded in the observation box 5 close to the mesh helmet 1, and an objective lens 7 is embedded and fixed on the side of the observation box 5 away from the mesh helmet 1, and the center point of the objective lens 7 and the center point of the eyepiece 9 are located on the same center line.

[0046] The supporting assembly includes a supporting rod 2, which is fixedly connected to the top of the net helmet 1 with transverse bolts, a first motor 20 is embedded and installed on the side of the supporting rod 2 away from the net helmet 1, an adjusting rod 3 is fixedly connected to the output shaft of the first motor 20 with bolts, a second motor 21 is embedded and installed on the bottom of the adjusting rod 3, a center frame 6 is fixedly connected to the output shaft of the second motor 21 with bolts, and both ends of the center frame 6 are fixedly connected to the side of the observation box 5 away from the adjusting box 4 with bolts; a controller is used to control the opening and closing of the first motor 20 and the second motor 21.

[0047] The specific implementation process is as follows:

[0048] At the beginning of the operation, the doctor puts the mesh helmet 1 on his head, and then controls the first motor 20 and the second motor 21 to start according to the height of his eyes through the controller. The output shaft of the first motor 20 drives the adjustment rod 3 to rotate, and the second motor 21 drives the center frame 6 to rotate, so that the eyepiece 9 is aligned with the eyes, which is convenient for subsequent better observation of the patient's internal body conditions.

[0049] After the angle adjustment is completed, the doctor starts the electric cylinder 10 through the controller, and the output axis of the electric cylinder 10 extends toward the center rod 12, so that the arc plate 11 slides forward on the sliding groove; when the arc groove contacts the guide block 17, the forward force of the arc groove will generate a shear force on the guide block 17, and the arc-shaped trajectory of the arc groove will have a limiting effect on the guide block 17, so that the guide block 17 rotates according to the trajectory of the arc groove.

[0050] At this time, the guide block 17 drives the rotating block 13 to start rotating on the center rod 12, and the rotating block 13 drives the magnifying lens 14 to rotate through the rotating slot 16 and enter the observation box 5. At this time, the center point of the magnifying lens 14 is on the same center line as the center point of the eyepiece 9 and the objective lens 7, so as to align with the patient's surgical position, and the magnifying lens 14 magnifies the surgical position in the patient's body; the greater the extension distance of the arc plate 11, the more magnifying lenses 14 are aimed at the surgical position, and due to the superposition effect of the magnifying lenses 14, the more magnifying lenses 14 are, the stronger the magnifying effect of the surgical position is.

[0051] The track of the arc groove allows the arc plate 11 to rotate only 90°, thereby ensuring that the arc plate 11 can accurately align the magnifying lens 14 with the observation point and the rotating block 13 can accurately return to its original position.

[0052] When the magnification needs to be reduced, the doctor controls the electric cylinder 10 to retract through the controller, and the output shaft of the electric cylinder 10 drives the arc plate 11 to retract, and the arc groove causes the guide block 17 to rotate in the opposite direction, and the guide block 17 drives the rotating block 13 to return to its original position, and the lens 14 is retracted, and the magnification is reduced. The doctor can control the telescopic distance of the electric cylinder 10 through the controller according to the magnification required by the doctor, so as to quickly and accurately adjust it, thereby improving the efficiency of the operation.

[0053] The present invention uses the design of the electric control cylinder 10 and the arc plate 11, so that the doctor can easily adjust the position of the magnifying lens 14 through the controller, thereby realizing a rapid change in the observation magnification. This design avoids the cumbersome process of replacing the eyepiece 9, the magnifying lens 14 and the objective lens 7 in traditional surgery, greatly improving the surgical efficiency. Since the magnification can be adjusted quickly, the doctor can observe the patient's internal conditions more accurately, reducing the surgical risk, improving the safety of the surgery, and thus greatly improving the quality of the surgery.

[0054] The design of the rotating blocks 13 and the magnifying lens 14 of the present invention cooperates with the eyepiece 9 and the objective lens 7 by rotating, so that the device is more adaptable to different surgical environments and surgical needs. The doctor can quickly adjust the observation angle and magnification according to the actual situation to adapt to different surgical sites and surgical steps.

[0055] The design of the mesh helmet 1 of the present invention enables the doctor to maintain a comfortable head posture during the operation, reduces fatigue caused by long-term surgery, and improves the operation efficiency and the doctor's concentration.

[0056] Embodiment 2:

[0057] As attached Figure 2 , Figure 3 , Figure 5 As shown, the difference from the above embodiment is that the rotation groove 16 is bolted and fixedly connected to the limit block 15 on both sides near the rotation block 13. The rotation block 13 is fixedly bonded with a magnetic plate 22 on both sides near the limit block 15, and the limit block 15 is made of metal.

[0058] The specific implementation process is as follows:

[0059] When the rotating block 13 rotates, the limiting block 15 can prevent the position of the rotating block 13 from being offset, so that the magnifying lens 14 can stably enter the rotating groove 16, so that the magnifying lens 14 can stably realize the magnification function.

[0060] When the rotating block 13 is stationary, the magnetic plate 22 and the limit block 15 are attracted to each other, so that the rotating block 13 remains fixed and prevents the rotating block 13 from rotating, thereby providing a good premise for the subsequent arc plate 11 to drive the rotating block 13 to rotate using the arc groove. The shear force generated by the arc groove on the guide block 17 is greater than the adsorption force of the magnetic plate 22 on the limit block 15.

[0061] Embodiment 3:

[0062] As attached Figure 2 As shown, the difference from the above embodiment is that a temperature regulator 18 is fixedly connected to the inner wall of the regulating box 4 with bolts.

[0063] The specific implementation process is as follows:

[0064] During the operation, the lens of the surgical magnifier may be fogged due to the temperature difference between the operating room and outside, the irradiation of the surgical light, the heat of the doctor's head, etc., thus affecting the clarity of the surgical field of view. The existence of the temperature regulator 18 can effectively control the temperature in the regulating box 4, avoid the lens from fogging due to excessive temperature difference, and ensure that the doctor can clearly observe the surgical site during the operation.

[0065] Embodiment 4:

[0066] As attached Figure 1 As shown, the difference from the above embodiment is that a plurality of tilting rods are bolted and fixedly connected between the support rod 2 and the mesh helmet 1 .

[0067] The specific implementation process is as follows:

[0068] The presence of the tilt rod enables a more firm and stable connection between the support rod 2 and the mesh helmet 1, thereby improving the overall stability of the device and enabling the doctor to perform surgery better.

[0069] Embodiment 5:

[0070] As attached Figure 1 As shown, the difference from the above embodiment is that corresponding interface ropes 8 are fixedly bonded to both sides of the bottom of the net helmet 1.

[0071] The specific implementation process is as follows:

[0072] After the doctor puts the mesh helmet 1 on the head, the interface ropes 8 on both sides of the face are connected to the lower jaw correspondingly, so that the whole device is more stable, so that the doctor can perform the operation better.

[0073] Embodiment 6:

[0074] As attached Figure 1 , Figure 4 As shown, the difference from the above embodiment is that a camera 19 is bolted and fixedly connected to the side of the center frame 6 away from the net helmet 1, and the controller is used to control the operation of the camera 19. A plurality of LED lights 23 are fixedly bonded to the side of the center frame 6 away from the net helmet 1, and the controller is used to control the operation of the LED lights 23.

[0075] The specific implementation process is as follows:

[0076] During the operation, the LED light 23 can provide sufficient and uniform lighting for the operation area, so that the doctor can observe the operation site more clearly, thereby improving the success rate and safety of the operation.

[0077] During the operation, the camera 19 can record the entire operation process, which is used for postoperative analysis, teaching and resolution of medical disputes. At the same time, the image of the operation process can be transmitted in real time, which is convenient for doctors to consult with other medical teams in real time, thereby improving the quality of the operation.

[0078] During the operation, the doctor's head will shake to a certain extent. The controller will lock the operation position according to the camera 19, and adjust the position of the adjustment rod 3 and the center frame 6 through the first motor 20 and the second motor 21 to ensure that the objective lens 7 is aligned with the patient's operation position, so that the doctor can observe the patient's operation position at any time during the long operation, thereby improving the quality of the operation.

[0079] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
