Description

Technical Field

[0001] This invention belongs to the technical field of the biomedical engineering industry, specifically relating to a light source camera suction device for minimally invasive spinal surgery. Background Technology

[0002] In the field of spinal surgery, precise manipulation and a clear surgical field are key elements for surgical success. As spinal surgery techniques evolve towards refinement and minimally invasive techniques, the demands for integrated and intelligent surgical instruments are increasing. Simultaneously, the biomedical engineering industry, as a core industry integrating engineering and life sciences, is driving the upgrading of surgical instruments towards multifunctional integration, minimally invasive techniques, and precision. Spinal minimally invasive surgical instruments, as an important branch of this industry, directly impact the safety and efficiency of clinical surgery through technological innovation.

[0003] Conventional spinal surgical instruments have numerous limitations in terms of lighting, imaging, and suction functions: traditional surgical lights struggle to accurately focus light onto the deep, narrow surgical areas of the spine, resulting in shadows or insufficient light in the surgical field, affecting the surgeon's observation and identification of subtle anatomical structures; minimally invasive surgeries involve smaller incisions, making it difficult for assistants to observe the surgical area and coordinate operations promptly, and the suction power of traditional suction devices is not easily controlled precisely, with the suction tube design potentially obstructing the surgeon's view. Furthermore, the lack of effective integration of lighting and imaging functions can lead to delayed removal of blood and tissue debris from the surgical area, interfering with the surgical process, reducing efficiency, prolonging operation time, and increasing the risk of surgical trauma and postoperative complications. In addition, existing spinal surgical instruments often feature multiple openings for decompression, and adjusting suction power by sealing the number of openings is inaccurate. Multiple openings also increase the complexity of the instrument structure, failing to meet the design requirements of the biomedical engineering industry for miniaturized and simplified instruments. Existing spinal surgery instruments are no longer sufficient to meet the clinical needs for minimally invasive and precise procedures. There is an urgent need to develop a new type of instrument that integrates efficient lighting, high-definition imaging, and precise suction to promote the coordinated development of minimally invasive spinal surgery techniques and the biomedical engineering industry.

The hollow tube has a hollow structure, and the lighting lamp and camera are built into the hollow tube, with a suction tube disposed inside the hollow tube. The hollow tube is fixedly installed inside the mounting block, and the hand handle is fixedly installed below the mounting block.

A connecting shaft is integrally formed below the adjusting rod, and both the upper and lower ends of the connecting shaft are provided with limit positions. The adjusting plate is sleeved inside the connecting shaft and is located between the two limit positions. The adjusting plate is slidably connected inside the pressure relief chamber, and the inner side of the T-block is inclined.

[0008] The present invention further illustrates that the inner walls of the pressure relief chamber are integrally formed with limit blocks on both the left and right sides. The inner shaft of the limit block is connected to a shaft rod. The T-shaped block has a through hole inside, and the shaft rod is inserted into the through hole. The lower end of the shaft rod is fixed with a connecting block. Electromagnetic blocks are fixed on the inner side of the connecting block. The outer walls of the T-shaped block and the connecting block are in contact with the inner wall of the pressure relief chamber.

[0009] The present invention further explains that both of the electromagnetic blocks are electrically connected to an external power source and become magnetic after being energized.

Detailed Implementation

[0015] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0016] Please see Figures 1-6 The present invention provides a technical solution: a light source camera suction device for minimally invasive spinal surgery, comprising a hollow tube 1, a mounting block 2, a lighting lamp 3, a camera 4 and a hand handle 8. The hollow tube 1 has a hollow structure, the lighting lamp 3 and the camera 4 are built into the hollow tube 1, and a suction tube 5 is provided inside the hollow tube 1. Hollow tube 1 is fixedly installed inside mounting block 2, and handle 8 is fixedly installed below mounting block 2. The upper part of hollow tube 1 is connected to pressure relief chamber 6. The pressure relief chamber 6 is equipped with a suction adjustment mechanism, which is used to adjust the suction force of the suction component. The lighting lamp 3 is a cold light source and is connected to light guide material. The camera 4 is connected to an image transmission line, and both the light guide material and the image transmission line are connected inside the line tube 7. The lower end of the line tube 7 extends out of the lower end of the handle 8. The suction adjustment mechanism includes an adjustment rod 61, two T-shaped blocks 62, and an adjustment plate 63. The adjustment rod 61 is threaded into the interior of pressure relief chamber 6, and the adjustment plate 63 is connected to the lower end of the adjustment rod 61. Air grooves are provided on both the left and right sides and are embedded in the two T-shaped blocks 62 through the air grooves. Pressure relief hole 64 is provided at the upper end of pressure relief chamber 6.

[0017] Camera 4 is a miniature camera. Camera 4 is located at the right end of hollow tube 1. The bottom of decompression chamber 6 is connected to suction tube 5. The right end of suction tube 5 is suction port, and the left end is suction interface. The suction interface is connected to external power equipment. The image transmission line is connected to an image display device. The suction tube 5 mainly consists of a suction port and a rear suction interface. The suction interface is connected to an external power device to release suction. Debris and blood generated during the operation are extracted through the suction port and suction channel to maintain a good surgical field. Based on the suction device, an illumination lamp 3 and a camera 4 are added. Signals and current are transmitted through a circuit tube 7, allowing the illumination lamp 3 and camera 4 to operate simultaneously for cold light illumination and real-time video recording. Cold light illumination avoids excessive heat generation during surgery, preventing thermal damage to surrounding tissues. The light guide material is imported high-transmittance optical fiber, featuring good color temperature, high illuminance, and concentrated light spot. The camera 4 records video in real time and transmits the image to an image display device via an image transmission line. It has sufficiently high pixels to provide clear images. The right end of head 4 is positioned near the suction port to provide a better field of view. The image transmission line is placed in the suction pipe structure and connected to the line pipe 7. The camera image is transmitted to the display device through the transmission line. In addition, the operator can rotate the adjusting rod 61, which moves up and down through the threaded drive, thereby moving the adjusting plate 63 up and down to adjust the distance between the air groove and the T-block 62, thereby reducing pressure and adjusting the suction force of the suction device to adapt to different surgical needs. It can effectively suck up liquids and tissue debris, while avoiding damage to nerves and spinal cord due to excessive suction. The light source camera suction device can reduce the frequency of surgical instrument replacement, improve surgical efficiency, reduce surgical complications, and help novice surgeons learn surgical techniques.

[0018] The upper end of the pressure relief chamber 6 is provided with a threaded hole, and the adjusting rod 61 is threaded into the threaded hole. The lower part of the adjusting rod 61 is integrally formed with a connecting shaft 611, and both the upper and lower ends of the connecting shaft 611 are provided with limit positions. The adjusting plate 63 is sleeved inside the connecting shaft 611 and is located between the two limit positions. The adjusting plate 63 is slidably connected inside the pressure relief chamber 6. The inner side of the T-block 62 is inclined. The operator rotates the adjusting rod 61, causing it to move up and down through the threaded hole. This, in turn, drives the adjusting plate 63 to move up and down along the inner wall of the decompression chamber 6 via the connecting shaft 611. This changes the gap between the inner side of the air groove and the inclined part of the T-shaped block 62, creating negative pressure inside the suction tube 5. Simultaneously, the pressure inside the suction tube 5 is reduced through the pipe, the gap, and the decompression hole 64. The suction force can be adjusted by rotating the adjusting rod 61. The adjustment is convenient and quick, and the suction force adjustment is highly precise, greatly improving the safety of the surgery.

[0019] The inner walls of the pressure relief chamber 6 are integrally formed with limit blocks 65 on both the left and right sides. The inner shaft of the limit block 65 is connected to the shaft rod 651. The T-shaped block 62 has a through hole, and the shaft rod 651 is inserted into the through hole. The lower end of the shaft rod 651 is fixed with a connecting block 652. Electromagnetic blocks 66 are fixed on the inner side of the connecting block 652. The outer walls of the T-shaped block 62 and the connecting block 652 are in contact with the inner wall of the pressure relief chamber 6.

[0020] Both electromagnetic blocks 66 are electrically connected to an external power source and become magnetic when energized. Furthermore, by changing the direction of the current, the magnetic poles of the two electromagnetic blocks 66 can be changed.

[0021] The external power equipment connected to the attraction interface is equipped with a pressure recognition module. The pressure recognition module is used to identify the negative pressure of the external power equipment in real time. The electromagnetic block 66 is equipped with a current direction control module. The current direction control module is used to control the current direction of the electromagnetic block 66 according to the negative pressure of the external power equipment, thereby controlling the magnetic poles of the two electromagnetic blocks 66. When the negative pressure of the external power equipment is unstable, such as when the negative pressure decreases, the pressure recognition module detects the decrease and controls the current of the electromagnetic block 66 through the current direction control module. This causes the magnetic poles of the two electromagnetic blocks 66 to be opposite, generating magnetic attraction. The two electromagnetic blocks 66 approach and fit together, driving the shaft 651 to rotate through the connecting block 652. This, in turn, causes the T-shaped block 62 to rotate inward through the shaft. The distance between the inner side of the T-shaped block 62 and the air groove suddenly decreases, thus reducing the pressure reduction. This prevents the suction from being too weak due to excessively low negative pressure, ensuring the smooth suction of liquids and tissue debris. Conversely, when the negative pressure increases, the magnetic poles of the two electromagnetic blocks 66 are controlled to be opposite, causing them to repel each other. This increases the pressure reduction, effectively preventing a sudden increase in suction from affecting surgical safety. By controlling the pressure reduction in this way, the suction can be controlled without manual adjustment during surgery, further improving surgical safety and making the suction device more effective and intelligent.

[0022] The connecting shaft 611 has a tapered groove 612 inside, and a compression ring 67 is provided on the inner wall of the tapered groove 612. A push rod 671 is fixed to the lower end of the compression ring 67, and the push rod 671 is slidably connected to the connecting shaft 611. The lower end of the push rod 671 and the inner end of the electromagnetic block 66 are both spherical, and the electromagnetic blocks 66 come into contact with the lower end of the push rod 671 after they approach each other.

[0023] Both the connecting shaft 611 and the adjusting plate 63 are made of elastic material; When the electromagnetic blocks 66 are in contact with each other, they press the top rod 671, causing it to move upward. The pressing ring 67 then presses the connecting shaft 611 and the adjusting plate 63. The elastic deformation of both causes them to expand outward, further reducing the gap between the T-block 62 and the air groove. This significantly reduces the pressure reduction and further improves the safety of the surgery. The suction stability of the suction device is greatly improved. It can automatically adapt to the fluctuating negative pressure of the external power equipment to fully ensure the stability of negative pressure control. It operates automatically without human intervention.
