Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a bipolar electrocautery knife for surgery. Background Art

[0002] In the field of surgery, hemostasis is a crucial operation. Especially in some delicate operations and operations with high requirements for vascular treatment, efficient and accurate hemostasis methods are directly related to the success or failure of the operation and the patient's postoperative recovery. Traditional hemostasis methods, such as ligation hemostasis and compression hemostasis, have many limitations when facing some complex surgical scenarios. With the continuous advancement of medical technology, electrocautery as a new type of hemostasis tool has gradually been widely used in various types of surgeries. Electrocautery uses the heat generated by high-frequency current to coagulate and carbonize tissues, thereby achieving the purpose of hemostasis and cutting. Compared with traditional hemostasis methods, it improves surgical efficiency and accuracy, reduces the amount of bleeding during surgery, and provides a strong guarantee for the smooth progress of the operation.

[0003] At present, the basic structure of the common bipolar electrocautery knives for surgery on the market mainly includes a handle, a forceps head, and a rod body connecting the two. The handle is used for doctors to hold and operate, and usually press the forceps rod to achieve the opening and closing of the forceps head. The forceps head part is composed of two opposing electrodes. When current passes through, a high-frequency electric field is generated between the two electrodes, causing the ions in the tissue to vibrate rapidly, generating heat to achieve electrocoagulation and hemostasis. The rod body plays a role of connection and support, and wires are generally arranged inside to transmit current. This structural design meets the basic needs of conventional surgery to a certain extent and can complete hemostasis operations on most visible blood vessels.

[0004] However, in actual surgical applications, especially in high-risk spinal canal decompression surgery, existing bipolar electrocautery knives have exposed some obvious problems. For example, in the case of anterior cervical spine surgery, the conventional straight-headed forceps design cannot stop bleeding in advance when the posterior longitudinal ligament blocks the blood vessels, and often can only choose to directly cut the posterior longitudinal ligament. During the cutting process, there are a large number of venous plexuses in front of the spinal cord behind the posterior longitudinal ligament. Because of the obstruction of the ligament, there is no way to stop bleeding in advance, which will cause a large amount of venous bleeding. Due to the narrow operating range and continuous bleeding in the field of vision, the operation is often unable to proceed. This not only increases the scope of damage to the surrounding normal tissues, but also prolongs the operation time, increases the risk of surgery, and even worse, causes irreversible nerve damage to the patient. Therefore, the present invention provides a bipolar electrocautery knife for surgery to solve the shortcomings of the prior art. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a bipolar electrocautery knife for surgery, which solves the problem that the bipolar electrocautery knife in the prior art is difficult to directly operate when treating the blood vessels behind the posterior longitudinal ligament in anterior spinal surgery to stop bleeding.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A bipolar electrocautery knife for surgery, comprising: a handle, which is the basis of the entire electrocautery knife and is used to assemble and carry other structural parts; A hemostatic mechanism, which is arranged at one end of the handle and is used for hemostatic operation during surgery; An auxiliary mechanism is arranged at the other end of the handle, and the auxiliary mechanism is used to connect other structures externally. The auxiliary mechanism includes a connecting seat, one end of the connecting seat is fixedly connected to the other end of the handle, the outer side of the connecting seat is fixedly connected to a water pipe, and the outer side of the connecting seat is fixedly connected to an electric wire.

[0007] Preferably, one end of the water pipe is externally connected to physiological saline solution, and one end of the electric wire is plugged into an external power source.

[0008] Preferably, the other end of the water pipe is connected to the internal channel of the handle and is connected to the hemostasis mechanism, and one end of the electric wire passes through the handle and is connected to the hemostasis mechanism.

[0009] Preferably, the hemostasis mechanism includes a functional component and an operating component, the functional component includes a long rod, one end of the long rod is fixedly connected to one end of the handle, and the other end of the long rod is fixedly connected to the second clamp head.

[0010] Preferably, a sliding rod is slidably connected to the inner side of the long rod, one end of the sliding rod is fixedly connected to the first clamp head, and the outer side of the second clamp head is in contact with the outer side of the first clamp head.

[0011] Preferably, guide grooves are provided on adjacent sides of the first and second clamp heads, and a water hole is provided on one side of the second clamp head, and the water hole is connected to the guide groove.

[0012] Preferably, the operating assembly comprises a connecting seat, the connecting seat is fixedly connected to the outer side of the sliding rod, a pull rope is fixedly connected to the outer side of the connecting seat, and one end of the pull rope is fixedly connected to a pull ring.

[0013] Preferably, both sides of the outside of the sliding rod are fixedly connected with limit strips, the inner side of the long rod is provided with two limit grooves, the outer side of the limit strip is slidably connected to the inner side of the limit groove, the adjacent sides of the long rod and the sliding rod are fixedly connected with a telescopic rod, and the outer side of the telescopic rod is provided with a spring.

[0014] The present invention provides a bipolar electrocautery knife for surgery, which has the following beneficial effects: 1. The present invention separates the first and second clamp heads by pulling the pull ring, using a pull rope and a connecting seat to pull the slide bar to move. When the pull ring is released, the spring force causes the slide bar and the first clamp head to quickly reset, and the clamp heads are closed again. During the entire operation process, the doctor can easily open and close the clamp heads. The operation is simple and convenient, and multiple operations can be completed quickly, thereby improving the surgical efficiency. In addition, the special design of the two clamp heads can bypass the ligament for convenient hemostasis operations.

[0015] 2. During the electrocoagulation hemostasis process, the present invention allows physiological saline drawn from the water pipe to drip onto the surgical site through the channel composed of the water hole and the guide groove along the internal channel of the handle and the long rod, thereby lowering the temperature of the surgical site, playing a role in lubrication and isolation, effectively preventing adhesion of skin and flesh tissues, ensuring a clear surgical field of view, and reducing additional damage to the tissues.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Please see attached Figure 1 -Attached Figure 5 The embodiment of the present invention provides a bipolar electrocautery knife for surgery, including a handle 1. The handle 1 is the basic component of the entire electrocautery knife. Its design fully considers ergonomics, and its surface is made of non-slip material, which is convenient for doctors to hold comfortably for a long time. The handle 1 is provided with reasonable wiring and pipeline channels inside, which are used to assemble and carry other structural parts, and provide stable support for subsequent functional realization.

[0020] The hemostatic mechanism is arranged at one end of the handle 1 and is used for hemostatic operation during surgery. The hemostatic mechanism includes a functional component and an operating component. In the functional component, one end of the long bar 2 is firmly connected to the handle 1 to provide a support structure for the entire functional component. Its internal hollow design cooperates with the line layout of the water pipe 16 and the wire 17 to ensure the stable transmission of physiological saline and electric current. The other end of the long bar 2 is fixedly connected with the clamp head 2 7, which works in conjunction with the clamp head 1 6. The clamp head 2 7 and the clamp head 1 6 are both made of special shapes and materials to ensure high efficiency and safety during electrocoagulation hemostasis. The slide bar 3 slides on the inner side of the long bar 2, and the limit strips 4 fixed on both sides of the outside of the slide bar 3 are closely matched with the limit grooves 5 opened on the inner side of the long bar 2, limiting the movement trajectory of the slide bar 3 so that it can only slide in a straight line along the direction of the limit grooves 5, ensuring the stability and accuracy of the sliding of the slide bar 3 and avoiding deviation or jamming. The clamp head 1 6 connected to one end of the slide bar 3 realizes the opening and closing action with the clamp head 2 7 under the drive of the slide bar 3, completing the clamping and electrocoagulation hemostasis operation of the tissue. The telescopic rod 11 and the spring 12 act together between the long bar 2 and the slide bar 3. When the doctor pulls the pull ring 10 to move the slide bar 3, the spring 12 is stretched to store energy; after releasing the pull ring 10, the spring 12 releases energy, pushing the slide bar 3 to quickly reset, so that the clamp head 1 6 and the clamp head 2 7 are quickly closed, which is convenient for the doctor to perform the next operation. In the operating component, the connecting seat 8 is fixed on the outside of the slide bar 3, which plays the role of connecting the pull rope 9 and the slide bar 3, accurately transmitting the tension of the pull rope 9 to the slide bar 3, and realizing the control of the movement of the slide bar 3. One end of the pull rope 9 is connected to the connecting seat 8, and the other end is connected to the pull ring 10. As a force transmission medium, the doctor pulls the pull ring 10, with the help of the traction of the pull rope 9, to accurately control the movement of the slide bar 3, thereby realizing the opening and closing of the clamp head 1 6 and the clamp head 2 7. The design of the pull ring 10 conforms to the human finger gripping habit, which is convenient for the doctor to easily pass through and apply force with the index finger. Its position and angle are carefully designed to ensure that the doctor can naturally and comfortably control the action of the hemostatic mechanism during the operation. The auxiliary mechanism is arranged at the other end of the handle 1 for external connection with other structures. The auxiliary mechanism includes a connecting seat 15, one end of which is firmly connected to the handle 1 to provide a stable connection point for the water pipe 16 and the wire 17. The special interface design on the outside ensures that the water pipe 16 and the wire 17 are tightly connected and will not loosen or fall off during the operation. One end of the water pipe 16 is connected to a physiological saline container, which is connected to the internal channel of the handle 1 through the connecting seat 15 and then connected to the hemostatic mechanism. During the operation, the physiological saline is transported to the clamp head 1 6 and the clamp head 2 7, and discharged through the water hole 14 and the guide groove 13, which effectively prevents the adhesion of skin and flesh tissue during the electrocoagulation process and ensures the smooth progress of the operation. One end of the wire 17 is plugged into an external power source, which passes through the handle 1 through the connecting seat 15 and is connected to the hemostasis mechanism, providing the power required for electrocoagulation to the forceps head 1 6 and the forceps head 2 7, thereby achieving hemostasis operation on the tissue. The outer sides of the forceps head 1 6 and the forceps head 2 7 are fitted together, and a guide groove 13 is provided on the adjacent sides, so that a complete guide channel is formed when they are closed, so that the physiological saline can drip smoothly.The elbow design is specially designed for the hemostasis of blood vessels under the subcutaneous ligament tissue. It can accurately stop bleeding on blood vessels without cutting the ligament, reduce damage to surrounding tissues, and improve the safety and effectiveness of surgery. The water hole 14 opened on one side of the clamp head 7 is connected to the guide groove 13. It is the key channel for the physiological saline to flow out from the internal channel of the long rod 2 and reach the guide groove 13, ensuring that the physiological saline can accurately act on the surgical site to prevent tissue adhesion.

[0021] Specifically, when using a bipolar electrocautery knife for surgery, preparations must be made first. One end of the water pipe 16 is connected to a container of saline solution, and at the same time, one end of the wire 17 is plugged into an external power source. The good conductivity and insulating sheath of the wire 17 ensure safe and stable transmission of electrical energy. After preparation, the doctor can hold the handle 1. The ergonomic design and non-slip material of the handle 1 enable the doctor to maintain a comfortable and stable grip during long-term operation, effectively reducing hand fatigue and ensuring the accuracy of the operation. The doctor passes the pull ring 10 with his index finger. The shape and size of the pull ring 10 are carefully designed to fully fit the doctor's index finger's gripping habits, making it convenient for the doctor to apply force easily. At this time, the clamp head 1 6 and the clamp head 2 7 are in a closed state. The saline solution drawn from the water pipe 16 follows the pre-designed channel inside the handle 1, then enters the internal channel of the long rod 2, and is finally discharged from the water hole 14. The water hole 14 is connected to the guide groove 13 opened on the proximal side of the clamp head 2 7 and the clamp head 1 6. When the physiological saline is discharged from the water hole 14, it will drip to the surgical site through the channel formed by the two guide grooves 13. During the electrocoagulation hemostasis process, high temperature will make the skin and flesh tissues easily adhere, and the continuously dripping physiological saline can reduce the temperature of the surgical site, play a role of lubrication and isolation, effectively prevent the adhesion of skin and flesh tissues, ensure a clear surgical field of view, facilitate accurate operation by doctors, and also reduce additional damage to tissues. In addition, the elbow design composed of the clamp head 1 6 and the clamp head 2 7 breaks the shape limitation of conventional electrocautery knives. When dealing with hemostasis of blood vessels under the subcutaneous ligament tissue, the elbow can flexibly bypass the ligament and directly perform hemostasis operations on the blood vessels without cutting the ligament, reducing the damage of the operation to the surrounding normal tissues, reducing the surgical risk, and shortening the operation time, which is beneficial to the patient's postoperative recovery. When tissue clamping or electrocoagulation operation is required, the doctor pulls the pull ring 10, and the pull ring 10 transmits the pulling force to the pull rope 9 after being stressed. As a force transmission medium, the pull rope 9 accurately transmits the pulling force to the connecting seat 8, thereby pulling the slide bar 3 to move. Due to the precise matching of the limit strip 4 and the limit groove 5, the slide bar 3 can only move linearly along the direction of the limit groove 5, ensuring the stability and accuracy of the movement of the slide bar 3. The movement of the slide bar 3 drives the pliers head 1 6 connected thereto to move, so that the pliers head 1 6 and the pliers head 2 7 are separated, and the doctor can use the opened pliers head to grab or contact the tissue to be treated. When the pull on the pull ring 10 is released, the previously stretched spring 12 begins to release the stored elastic potential energy. The elastic force of the spring 12 pushes the slide bar 3 to quickly reset, thereby driving the pliers head 1 6 to quickly reset, so that the pliers head 1 6 and the pliers head 2 7 are closed again. This quick reset design facilitates the doctor to quickly perform the next operation after completing an operation, improves the efficiency of the operation, and during the entire operation, the doctor can easily open and close the pliers head by controlling the pull ring 10, which is simple and convenient to operate and meets the actual needs of the operation.

[0022] Working principle: First, one end of the water pipe 16 can be connected to a container filled with saline solution, and one end of the wire 17 can be plugged into an external power source. Then the doctor can hold the handle 1 and pass the index finger through the pull ring 10. When the clamp head 1 6 and the clamp head 2 7 are in the closed state, the saline solution drawn from the water pipe 16 can be discharged from the water hole 14 along the internal channel of the handle 1 and the long rod 2, and then drip through the channel formed by the two guide grooves 13, so as to prevent the adhesion of skin and flesh tissue. Moreover, the elbow design formed by the clamp head 1 6 and the clamp head 2 7 breaks the conventional electric cautery knife design. When dealing with hemostasis of blood vessels under the subcutaneous ligament tissue, the ligament can be bypassed without cutting it. The doctor can pull the pull ring 10 to pull the sliding rod 3 to move through the pull rope 9 to separate the clamp head 1 6 and the clamp head 2 7. When the pull on the pull ring 10 is released, the elastic force of the spring 12 can quickly reset the clamp head 1 6, so that the clamp head 1 6 and the clamp head 2 7 are in the closed state, which is convenient for the doctor to operate.
