Description

Technical Field

[0001] The utility model relates to a medical device, and more particularly to a surgical needle-type electronic imaging visualization puncture system. Background Art

[0002] Accurate positioning is crucial in many surgical procedures. For example, percutaneous nephrolithotomy is an effective and commonly used procedure for kidney stone removal. However, this procedure presents numerous challenges in creating a channel, including positioning issues and damage to surrounding vessels and tissues during puncture. Commonly used positioning methods include CT-guided visual puncture and ultrasound-guided fuzzy positioning puncture. CT-guided puncture versus visual puncture presents a significant risk of radiation exposure. While more accurate, the radiation exposure to patients is not negligible. While surgeons can wear lead vests throughout the puncture, anesthesiologists and circulating nurses often step out of the way, resulting in delayed monitoring of the patient's vital signs and an increased risk of accidents. Ultrasound-guided fuzzy positioning puncture, while harmless, places high demands on the surgeon and can lead to repeated punctures, inaccurate positioning, and even puncture failure, resulting in pneumothorax. Furthermore, creating a channel for intrahepatic bile duct stones is relatively cumbersome, resulting in a low rate of clinical application.

[0003] In conventional puncture, after successful positioning, the puncture channel needs to be expanded to improve the efficiency of lithotripsy during the operation, but this also leads to an increased risk of bleeding for patients and prolonged postoperative recovery time. Utility Model Content

[0004] In view of the problems existing in the above-mentioned prior art, the utility model provides a surgical needle-type electronic imaging visualization puncture system.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions, including a holmium laser channel, a needle-type electronic imaging mirror channel, a water inlet channel, a connecting puncture needle body, an oblique puncture inner needle, an outer-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 at the lower part of the connecting puncture needle body. The lower part of the connecting puncture needle body is flexibly connected to the oblique puncture inner needle and the outer-plane needle in turn, and the needle-type electronic imaging mirror can pass through the needle-type electronic imaging mirror channel.

[0006] The outer plane needle can also be placed on the outside of the bevel puncture inner needle, with the top directly connected to the lower part of the puncture needle body.

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

[0008] A sealing gel is provided at the connection between the holmium laser channel, the needle-shaped electronic imaging mirror channel and the puncture needle body, and a rotatable fixing nut is provided on the outside.

[0009] The middle part of the water inlet channel is connected with a water channel control valve, and the bevel puncture inner needle is provided with water inlet and outlet, which can be connected with a negative pressure suction device.

[0010] The needle-shaped electronic imaging mirror circuit is connected to the imaging system and provides a field of view through the needle-shaped electronic imaging mirror channel of the puncture needle body.

[0011] Beneficial effects of the utility model:

[0012] This utility model ensures the clarity of the surgical field of view through the clear pixel field of the needle-shaped electronic imaging scope. After the puncture is successful and the channel is established, the water inlet channel on the puncture needle connector and the water outlet of the bevel inner needle are connected to the negative pressure suction device to suck out the gravel. It can also be directly connected to the bevel outer needle for visual puncture and establishment of a traditional channel. The success rate of puncture is improved, and serious damage to surrounding tissues, blood vessels or organs is reduced. The stone can be directly collected and sucked out, reducing the difficulty of conventional surgical methods, reducing the difficulty of medical personnel, and reducing the pain of patients. The surgical channel is small and the patient's postoperative recovery speed is accelerated. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] It includes a holmium laser channel, a needle-type electronic imaging mirror channel, a water inlet channel, a connecting puncture needle body, an oblique puncture inner needle, an outer-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 at the lower part of the connecting puncture needle body. The lower part of the connecting puncture needle body is flexibly connected to the oblique puncture inner needle and the outer-plane needle in turn, and the needle-type electronic imaging mirror can pass through the needle-type electronic imaging mirror channel.

[0021] The outer plane needle can also be placed on the outside of the bevel puncture inner needle, with the top directly connected to the lower part of the puncture needle body.

[0022] The inner diameter of the bevel puncture needle is 4.2F, the outer diameter of the plane needle is 4.8F, the diameter of the needle-shaped electronic imaging mirror is 0.9mm, and the pixel is 160,000 pixels.

[0023] A sealing gel is provided at the connection between the holmium laser channel, the needle-shaped electronic imaging mirror channel and the puncture needle body, and a rotatable fixing nut is provided on the outside.

[0024] The middle part of the water inlet channel is connected with a water channel control valve, and the bevel puncture inner needle is provided with water inlet and outlet, which can be connected with a negative pressure suction device.

[0025] The needle-shaped electronic imaging mirror circuit is connected to the imaging system and provides a field of view through the needle-shaped electronic imaging mirror channel of the puncture needle body.

[0026] When in use, the percutaneous renal puncture accessory puncture needle, by correctly connecting the puncture needle, connecting the needle-type electronic imaging scope, connecting the water inlet channel and the water outlet channel, can control the valve through the water channel connected in the middle of the water inlet channel to adjust the size of the water flow. After the fuzzy puncture under ultrasound guidance, accurate puncture can be performed under the field of view of the needle-type electron microscope. The flowing water flow can provide a clear field of view. After puncturing to the location of the stone, the connected puncture needle body is removed, the inner needle of the bevel can be withdrawn, and the outer needle of the plane is left as a channel. The connected puncture needle body is connected to the outer needle of the plane, and the holmium laser optical fiber is inserted through the holmium laser channel. Under the field of view of the needle-type electronic imaging scope, the stone is reduced to 3mm in size, and the negative pressure suction device is connected to the water outlet of the outer needle to suck out the broken stone.
