Description

Technical Field

[0001] This invention relates to a medical device, and more specifically, to a surgical needle-type electronic imaging visualization puncture system. Background Technology

[0002] In many surgical treatments, accurate localization is crucial. For example, percutaneous nephrolithotomy (PCNL) is an effective and commonly used procedure for kidney stones. However, this procedure presents several challenges in creating the access pathway, including positioning issues during the puncture and potential damage to surrounding blood vessels and tissues. Common localization methods include CT-guided visualization puncture and ultrasound-guided fuzzy localization puncture. CT-guided visualization puncture carries significant radiation risks. While accurate, the radiation exposure cannot be ignored. Although surgeons can wear lead aprons for protection, anesthesiologists and circulating nurses typically avoid the area, potentially leading to delayed monitoring of vital signs and an increased risk of complications. Ultrasound-guided fuzzy localization puncture, while harmless, demands a high level of skill from the surgeon. Repeated punctures, inaccurate localization, and even puncture failure can occur, leading to complications such as pneumothorax. Furthermore, establishing access for intrahepatic bile duct stones is complex, resulting in a relatively low clinical application rate.

[0003] In a routine puncture, after successful localization, the puncture channel needs to be expanded to improve the efficiency of stone fragmentation during the procedure. However, this also increases the risk of bleeding for the patient and prolongs the postoperative recovery time. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention provides a surgical needle-type electronic imaging visualization puncture system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution, including a holmium laser channel, a needle-type electronic imaging mirror channel, a water inlet channel, a connecting puncture needle body, an inclined puncture inner needle, an out-of-plane needle, and a needle-type electronic imaging mirror. The holmium laser channel, the needle-type electronic imaging mirror channel, and the water inlet channel are fixedly connected to the upper part of the connecting puncture needle body. The three channels converge into one channel in the lower part of the connecting puncture needle body. The inclined puncture inner needle and the out-of-plane needle are movably connected sequentially to the lower part of the connecting puncture needle body. The needle-type electronic imaging mirror can pass through the needle-type electronic imaging mirror channel.

[0006] The flat external needle can also be fitted over the outside of the beveled puncture internal needle, with its top directly connected to the lower part of the connecting puncture needle body.

[0007] The diameter of the inner needle for bevel puncture is 4.2F, the diameter of the outer needle is 4.8F, the diameter of the needle-type electronic imaging mirror is 0.9mm, and the pixel count is 160,000 pixels.

[0008] The connection between the holmium laser channel, the needle-type electronic imaging mirror channel, and the puncture needle body is sealed with a gel, and a rotatable fixing nut is installed on the outside.

[0009] The middle of the water inlet channel is connected to a water channel control valve, and the inclined puncture needle has inlet and outlet ports, which can be connected to a negative pressure suction device.

[0010] The needle-type electronic imaging mirror circuit is connected to the imaging system, providing a field of view through the needle-type electronic imaging mirror channel of the puncture needle.

[0011] The beneficial effects of this invention are: This invention utilizes the clear, pixel-perfect field of view provided by a needle-type electronic imaging microscope to ensure a clear surgical view. After successful puncture and channel establishment, a negative pressure suction device is connected via the water inlet channel on the puncture needle connector and the water outlet of the beveled inner needle to aspirate the stones. Alternatively, it can be directly connected to the beveled outer needle for visualized puncture and establishment of a traditional channel. This improves the success rate of puncture, reduces serious damage to surrounding tissues, blood vessels, or organs, allows for direct aspiration of stones and fluid, reduces the difficulty of conventional surgical procedures, lowers the workload for medical personnel, reduces patient suffering, and, due to the smaller surgical channel, accelerates postoperative recovery.

Detailed Implementation

[0018] The invention will now be further described with reference to the accompanying drawings.

[0019] It includes a holmium laser channel, a needle-type electronic imaging mirror channel, a water inlet channel, a connecting puncture needle body, an inclined puncture inner needle, an out-of-plane needle, and a needle-type electronic imaging mirror. The holmium laser channel, the needle-type electronic imaging mirror channel, and the water inlet channel are fixedly connected to the top of the connecting puncture needle body. The three channels converge into one channel in the lower part of the connecting puncture needle body. The inclined puncture inner needle and the out-of-plane needle are movably connected in sequence at the bottom of the connecting puncture needle body. The needle-type electronic imaging mirror can pass through the needle-type electronic imaging mirror channel.

[0020] The flat external needle can also be fitted over the outside of the beveled puncture internal needle, with its top directly connected to the lower part of the connecting puncture needle body.

[0021] The diameter of the inner needle for bevel puncture is 4.2F, the diameter of the outer needle is 4.8F, the diameter of the needle-type electronic imaging mirror is 0.9mm, and the pixel count is 160,000 pixels.

[0022] The connection between the holmium laser channel, the needle-type electronic imaging mirror channel, and the puncture needle body is sealed with a gel, and a rotatable fixing nut is installed on the outside.

[0023] The middle of the water inlet channel is connected to a water channel control valve, and the inclined puncture needle has inlet and outlet ports, which can be connected to a negative pressure suction device.

[0024] The needle-type electronic imaging mirror circuit is connected to the imaging system, providing a field of view through the needle-type electronic imaging mirror channel of the puncture needle.

[0025] During use, the percutaneous nephrolithotomy (PCNL) puncture needle is properly connected to the needle-type electron imaging microscope, and the inlet and outlet water channels. The water flow can be adjusted by controlling the valve in the middle of the inlet water channel. After ultrasound-guided fuzzy puncture, accurate puncture can be performed under the field of view of the needle-type electron microscope. The flowing water provides a clear field of view. After puncturing to the stone location, the connecting puncture needle body is removed, and the inclined inner needle can be withdrawn, leaving the outer needle as a channel. The connecting puncture needle body is connected to the outer needle, and a holmium laser fiber is inserted through the holmium laser channel. Under the field of view of the needle-type electron imaging microscope, the stone is broken down to 3mm in size. The broken stone is then suctioned out through the outlet of the outer needle using a negative pressure suction device.
