Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically relates to a bipolar electrocoagulation hemostatic forceps with an aspiration function for brain surgery. Background Art

[0002] A bipolar electrocoagulation forceps is a medical electronic device mainly used for hemostasis and tissue cutting. Its basic principle is to coagulate the proteins of tissues using high-frequency electrical energy, thereby achieving the purpose of hemostasis and cutting. The bipolar electrocoagulation forceps has two electrodes, namely the positive electrode and the negative electrode, which can simultaneously generate high-frequency current and high-frequency voltage, thereby more precisely controlling the output of electrical energy. Compared with a monopolar electrocoagulation forceps, the bipolar electrocoagulation forceps has higher coagulation efficiency and less risk of burning tissues, and also has advantages such as being easy to use and simple to operate. Due to the various advantages of the bipolar electrocoagulation forceps, it is widely used in medical surgeries. During the surgery, the doctor selects appropriate current and voltage according to needs to coagulate and cut tissues, thereby achieving the purpose of hemostasis and tissue resection. For some relatively small bleeding points, they can be quickly coagulated. The bipolar electrocoagulation forceps transmits high-frequency electrical energy to both ends of the forceps. The tip of the forceps head is specially designed. Through the action of the current, it can concentrate the current and accelerate the cutting and hemostasis effects, and can precisely control the position of the action;

[0003] The tools in the surgery for craniocerebral injury include an aspiration tube, a bipolar electrocoagulation forceps, and an endoscope. The functions of the aspiration tube include sucking the blood in the surgical field, maintaining a clean surgical field, searching for bleeding points, incising the brain tissue, removing hematomas, removing inactivated fragmented brain tissues, assisting in exploring the brain surface at the base of the skull, sucking dry the cotton pads pressed on gelatin sponges, and assisting in hemostasis. When operating on the brain, a thinner aspiration tube should be replaced. The adjustment of the suction force can be adjusted through the adjustment of the wall suction device or by covering the number of openings on the side wall of the aspiration tube.

[0004] In summary, there are the following technical problems in the current cooperation process of using an aspiration tube and a bipolar electrocoagulation forceps in brain surgery: sucking the blood in the surgical field through the aspiration tube to expose the bleeding point, and using the bipolar electrocoagulation forceps to stop the bleeding at the bleeding point; while operating the above two instruments, there is also an endoscope that needs to be controlled. The operating space in brain surgery is limited. The image is transmitted on the screen through the endoscope, and the operator operates the instruments, which makes the operator's operation steps cumbersome, occupies the operator's hands, and limits the operation content. Summary of the Invention

[0005] In view of the above problems existing in the prior art, the present invention provides a bipolar electrocoagulation hemostatic forceps with an aspiration function for brain surgery. By combining an aspirator and a bipolar electrocoagulation forceps and designing a cooperation operation structure, the operator can control it with one hand, and the other hand can be used for other operations, without restricting the operation content of the operator.

[0016] The beneficial effects of the present invention:

[0017] A bipolar electrocoagulation hemostatic forceps with suction function for brain surgery. When in use, connect the connector to the negative pressure system on the wall. When there is a bleeding point and the blood obscures the bleeding point, the operator's index finger and thumb maintain the same gripping method as the existing operation method, and the middle finger is placed on the pressing ring on one side of the operating frame. When suction is required, press the plug column pressing ring. When the extension tube needs to be inserted deeper to suck the blood, press the pressing ring. The push column of the pressing plate pushes the gas in the folding trachea and pushes the gas into the adjusting cylinder. The gas pushes the extension tube in the adjusting cylinder, making the extension tube go deeper to completely suck the blood. After the suction is completed, the middle finger releases the pressing frame and the extension tube resets. Use the tip of the electrocoagulation forceps to clamp the bleeding point to complete hemostasis. When adjusting the suction position of the extension tube, the finger pressing the pressing frame slides up or down. While keeping the pressing frame pressed, the lever in the pressing frame rotates around the fixed axis and moves up and down in the rear plate. Through the cooperation of the sliding groove of the lever and the slider, and the cooperation of the upper rotating frame and the rotating shaft, the adjusting rod moves up and down on the operating frame. When the adjusting rod moves up and down, it drives the adjusting cylinder to move up and down, thereby changing the suction position of the extension tube for suction. During the up and down movement of the adjusting rod and the adjusting cylinder, the rear soft ring and the front soft ring cooperate to undergo elastic deformation, completing the overall single-handed operation of suction and hemostasis, enabling the operator to free up a hand to operate an endoscope, etc. The gripping method of the electrocoagulation forceps and the operating method of the suction device are the same as those in the prior art, without changing the operation steps and not delaying the surgical process.

[0018] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
