Description

Technical Field

[0001] The utility model relates to the technical field of bipolar electrodes, and more particularly to a bipolar electrode for transnasal skull base surgery. Background Art

[0002] Transnasal skull base surgery is a minimally invasive surgical technique that treats lesions in the skull base area through the natural passages of the nasal cavity. This surgical method does not require an incision on the face or head. The doctor uses a special endoscope and surgical instruments to reach the base of the skull through the nasal cavity to remove tumors or other abnormal tissues. This method can reduce surgical trauma, help patients recover faster, and reduce the risk of facial scarring.

[0003] In transnasal skull base surgery, the working principle of bipolar electrodes mainly relies on high-frequency current. When the current passes through the two electrodes, it generates heat energy, which can be used to cut tissue or coagulate blood vessels. Since the current mainly flows between the electrodes, the thermal damage to the surgical area is limited to a very small range, which helps to reduce surgical trauma and postoperative recovery time.

[0004] What are the shortcomings of existing bipolar electrodes used for transnasal skull base surgery?

[0005] First, bipolar electrodes are mainly used to stop bleeding during surgery. When the electrodes come into contact with tissue, they can cause tissue damage. Especially when the heat is set too high or the contact time is too long, the fluid in the tissue can seep out. The high temperature of the bipolar electrodes can cause the fluid in the tissue to evaporate, blurring the surgical field of view and increasing the difficulty of the surgery.

[0006] Second, when using a bipolar electrode, the bipolar electrode is operated by holding it in a manner similar to holding a gun, which makes it difficult for the doctor to accurately control the tip of the bipolar electrode, which may cause accidental injury to surrounding tissues. Utility Model Content

[0007] In order to overcome the above-mentioned defects of the prior art, the present invention provides a bipolar electrode for transnasal skull base surgery to solve the problems existing in the above-mentioned background technology.

[0008] The utility model provides the following technical solution: a bipolar electrode for transnasal skull base surgery, comprising a grip, the front surface of the grip is fixedly connected to an insertion catheter, the front end of the outer surface of the insertion catheter is fixedly connected to a suction sleeve, the inner surface of the suction sleeve is movably connected to a first transmission tube, one end of the first transmission tube is fixedly connected to a suction pump, the front end of the insertion catheter is provided with an electrode sheet, and the back surface of the electrode sheet is fixedly connected to a second driving rod;

[0009] Furthermore, pressure sensors are fixedly connected to both sides of the outer surface of the grip, pressure adjustment blocks are provided on both sides of the grip, and a conductive wire is fixedly connected to the back side of the grip.

[0010] Furthermore, a through groove is provided on the inner surface of the suction sleeve, a first transmission tube is movably connected to the inner surface of the through groove, a suction port is provided on the outer surface of the suction sleeve, and a collection box is movably connected to the outer surface of the first transmission tube.

[0011] Furthermore, the inner surface of the collection box is fixedly connected to a suction pump, the top of the suction pump is fixedly connected to a water suction port, the top of the water suction port is fixedly connected to a first transmission pipe, the front of the suction pump is fixedly connected to a discharge port, and the bottom of the collection box is fixedly connected to a second transmission pipe.

[0012] Furthermore, the inner surface of the insertion catheter is fixedly connected to a cylinder, the front side of the cylinder is fixedly connected to a telescopic rod, the top of the telescopic rod is movably connected to a first driving rod, the middle part of the first driving rod is movably connected to a first movable pin, the bottom of the first movable pin is movably connected to the telescopic rod, the front end of the first driving rod is movably connected to a second movable pin, the bottom of the second movable pin is movably connected to the second driving rod, the middle part of the second driving rod is movably connected to a third movable pin, and the bottom of the third movable pin is movably connected to the inner wall of the grip rod.

[0013] Furthermore, the pressure sensor is of the model of Omron SMPP, which can accurately sense and convert pressure signals.

[0014] The technical effects and advantages of this utility model are:

[0015] 1. This utility model achieves control of the electrode pad through the linkage of a pressure sensor and a pneumatic cylinder. When the pressure adjustment block is pinched and contacts the pressure sensor, the telescopic rod can be quickly moved to control the opening or closing of the electrode pad. This control allows the doctor to more accurately control the tip of the electrode pad, reducing the risk of accidental contact or injury to surrounding tissue.

[0016] 2. In the present invention, when the electrode sheet contacts the patient's skin tissue and needs to remove the accumulated fluid, the suction pump is started, and the suction port transmits the suction force to the first transmission tube. At this time, the accumulated fluid flows into the through groove through the suction port in the suction sleeve. At this time, the accumulated fluid flows into the collection box through the first transmission tube and is then discharged through the second transmission tube. This is beneficial to avoid the obstruction of the surgical field of view by the accumulation of accumulated fluid, so that the doctor can observe the surgical site more clearly and reduce the possibility of misoperation.

[0028] In a preferred embodiment, the pressure sensor 101 is of model Omron 2SMPP-03, which can accurately sense and convert pressure signals.

[0029] The working principle of the present invention is as follows: when it is necessary to control the use of the electrode sheet 307, pinch the pressure adjustment block 103 so that one end of the pressure adjustment block 103 touches the pressure sensor 101, and the pressure sensor 101 transmits the electrical model to the cylinder 3. At this time, the telescopic rod 301 starts to move forward to make the first drive rod 303 open outward. After the first drive rod 303 opens outward, the electrode sheet 307 is moved inward under the action of the second movable pin 304 and the third movable pin 306. The control of the electrode sheet 307 is achieved through the linkage between the pressure sensor 101 and the cylinder 3.
