Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an ultra-low radiation dose endoscopic C-arm machine for chest surgery. Background Art

[0002] Before surgery to remove lung lesions (such as lung tumors and lung nodules), cardiothoracic surgeons need to locate these lesions to facilitate precise resection during surgery.

[0003] At present, conventional positioning methods include invasive positioning and non-invasive positioning:

[0004] 1. Invasive positioning relies on the hook at the end of the puncture needle to fix the lesion on the lung tissue, but it causes great trauma, bleeding affects the positioning effect, and unhooking often occurs.

[0005] 2. Non-invasive positioning relies on preoperative three-dimensional CT imaging, which is highly subjective and requires high clinical experience of cardiovascular surgeons.

[0006] Therefore, in order to solve the aforementioned problems, we propose an ultra-low radiation dose endoscopic C-arm machine for thoracic surgery. Summary of the invention

[0007] The purpose of the present invention is to solve the defects in the prior art and to propose an ultra-low radiation dose endoscopic C-arm machine for chest surgery.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] An ultra-low radiation dose endoscopic C-arm machine for chest surgery, comprising a control handle, a rod body is fixedly mounted on one end of the control handle, an X-ray light source is fixedly mounted on one end of the rod body, and a clamp and a sensor assembly are movably mounted on the outer surface of the X-ray light source in sequence from front to back;

[0010] A control ring is slidably mounted on the outer surface of one end of the rod body close to the control handle, and a control rod is movably mounted below the control handle;

[0011] Two push rods 1 and two push rods 2 are installed inside the rod body, and the two ends of the two push rods 1 are respectively connected to the sensor assembly and the operating rod, and the two ends of the two push rods 2 are respectively connected to the clamp and the operating ring.

[0012] Furthermore, the clamp includes a clamping frame, two connecting rods, and a clamping block. The clamping frame is movably mounted on the outer surface of the X-ray light source, one end of the two connecting rods is movably connected to the two ends above the clamping frame, the other ends of the two connecting rods are respectively movably connected to the front ends of the two push rods, and the clamping block is fixedly mounted at the bottom inside the clamping frame.

[0013] Furthermore, the sensor assembly includes a mounting frame and an X-ray imaging sensor, the X-ray imaging sensor is fixedly mounted at the bottom inside the mounting frame, the mounting frame is movably mounted on the outer surface of the X-ray light source, and the front ends of the two push rods are movably connected to the two sides of the mounting frame respectively.

[0014] Furthermore, the X-ray light source adopts ultra-low dose X-ray technology.

[0015] Furthermore, the push rod 1, the connecting rod, the clamping frame, the push rod 2, and the mounting frame are all made of medical-grade stainless steel, and the surfaces are treated for corrosion resistance and biocompatibility.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] By using the present invention, it is possible to achieve the goal of not needing to perform positioning before surgery. By taking advantage of the small size of the device, it can be placed in the chest cavity through the hole of a minimally invasive thoracoscope, and the position of the lung space-occupying part can be observed on an external screen, which is conducive to improving the accuracy of diagnosis. At the same time, the radiation dose of the device is low, and the impact on the health of patients and doctors is small.

[0018] The present invention has a compact design and is easy to operate. It can easily adjust the direction and height of the clamp and the sensor assembly to facilitate its fitting with different lung lobe tissues; it can easily control the clamping of the clamp and the sensor assembly and the shooting of the X-ray irradiator. The device is not only suitable for complex lung surgeries, but also for various diagnostic procedures that require precise image guidance, such as lung biopsy, lung nodule assessment, etc., broadening its scope of clinical application.

[0019] This device uses advanced radiation protection technology to ensure that the radiation dose received by patients and medical teams during the entire examination or operation is reduced to the lowest level, in line with international safety standards, and reducing long-term health risks.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention;

[0026] Reference Figure 1-3 An ultra-low radiation dose endoscopic C-arm for chest surgery includes a control handle 1, a rod body 4 is fixedly mounted on one end of the control handle 1, an X-ray light source 5 is fixedly mounted on one end of the rod body 4, and a clamp and a sensor assembly are movably mounted on the outer surface of the X-ray light source 5 from front to back; a control ring 3 is slidably mounted on the outer surface of the rod body 4 near the control handle 1, and a joystick 2 is movably mounted below the control handle 1; two push rods 1 6 and two push rods 2 10 are respectively mounted inside the rod body 4, and the two ends of the two push rods 1 6 are respectively connected to the sensor assembly and the joystick 2, and the two ends of the two push rods 2 10 are respectively connected to the clamp and the control ring 3. The sensor assembly includes a mounting frame 11 and an X-ray imaging sensor 12, and the clamp includes a clamp frame 8, two connecting rods 7, and a clamp block 9.

[0027] During surgery, the device can be placed into the chest cavity through the hole of a minimally invasive thoracoscope, and the clamp and the sensor assembly can be driven to rotate by the operating ring 3 and the operating rod 2 to clamp the lung lobe tissue;

[0028] After the clamp and sensor assembly fix the lung tissue, the X-ray light source 5 is started, so that high-quality X-rays can be taken in a small range, and in conjunction with the X-ray imaging sensor, the doctor can accurately identify and locate the tumor in the lung lobe, including its precise position and size, providing a key basis for formulating a personalized surgical plan. The X-ray imaging sensor can be connected to an external imaging device, and medical personnel can observe the position of the lung space on an external screen, which is conducive to improving the accuracy of diagnosis.

[0029] The X-ray source 5 uses ultra-low-dose X-ray technology to emit high-precision X-rays in a very small range, which greatly reduces the risk of radiation exposure for patients and medical staff compared to traditional C-Arm equipment. By precisely controlling the intensity and direction of the X-rays, it can clearly present the structural details inside the lung lobes without damaging surrounding tissues.

[0030] The X-ray imaging sensor 12 is fixedly mounted at the bottom of the mounting frame 11 , and the mounting frame 11 is movably mounted on the outer surface of the X-ray light source 5 . The front ends of the two push rods 10 are movably connected to the two sides of the mounting frame 11 .

[0031] Medical personnel can pull the operating ring 3 backward to make the push rod 10 pull the mounting frame 11 to rotate downward. At this time, the X-ray imaging sensor 12 can be moved to one side of the lung lobe tissue, so that the X-ray imaging sensor 12 is in the working position and waits for subsequent clamping operations.

[0032] The clamping frame 8 is movably installed on the outer surface of the X-ray light source 5, one end of the two connecting rods 7 is movably connected to the two ends above the clamping frame 8, and the other ends of the two connecting rods 7 are movably connected to the front ends of the two push rods 6 respectively, and the clamping block 9 is fixedly installed at the bottom inside the clamping frame 8.

[0033] Medical personnel can grip the joystick 2 to move the front end of the push rod 6 forward, thereby pushing the upper part of the clamping frame 8 through the connecting rod 7, so that the clamping frame 8 rotates downward, and the clamping block 9 cooperates with the sensor assembly to clamp the lung lobe tissue. The clamping block 9 can gently and firmly clamp the lung lobe tissue, reduce movement, and create ideal conditions for the subsequent X-ray shooting.

[0034] The push rod 1 6 , the connecting rod 7 , the clamping frame 8 , the push rod 2 10 , and the mounting frame 11 are all made of medical-grade stainless steel, and the surface is treated with anti-corrosion and biocompatibility to ensure stability and safety during the operation.
