Description

Technical Field

[0001] The present invention relates to medical devices, and more specifically to a bipolar electrosurgical knife and its usage method. Background Art

[0002] Electrosurgical knives are commonly used medical devices in surgical operations, which have two functions: electrocutting and electrocoagulation hemostasis. Currently, there are monopolar electrosurgical knives and bipolar electrosurgical knives on the market, both of which adopt a pen-holding operation method, and the thumb or index finger presses the operation button for electrocutting or electrocoagulation operations. Generally, monopolar electrosurgical knives are used in surgeries, and bipolar electrosurgical knives are occasionally used in some surgeries. Therefore, when performing relevant surgical operations, it is necessary to equip bipolar electrosurgical knives, monopolar electrosurgical knives, forceps and other instruments at the same time. This not only increases the cost of the instruments, but also the variety of surgical instruments is numerous, which is not conducive to placement. Summary of the Invention

[0003] In view of the above technical problems, the present invention provides a monopolar-to-bipolar electrosurgical knife that can reduce costs and is convenient to operate.

[0004] The technical solution adopted by the present invention to solve the above technical problems is as follows: A monopolar-to-bipolar electrosurgical knife includes a monopolar electrosurgical knife and further includes a bipolar device. The bipolar device is movably connected to the knife head of the monopolar electrosurgical knife through a connector, and the monopolar electrosurgical knife controls the electrical operation of the bipolar device through the connector.

[0008] Preferably, the conductive column is fixedly formed on the body.

[0009] Preferably, the connector is a through hole provided on the body, and the knife head is inserted into the through hole to be electrically connected to the body.

[0015] (2) Then electrically connect the knife head of the monopolar electrosurgical knife to the bipolar device through a connector;

[0016] (3) Then hold the above-mentioned monopolar electrosurgical knife in the palm of the hand, and pinch the bipolar device with the thumb and index finger;

[0017] (4) During electrooperation, press the electrocoagulation key or the electrosection key of the operation button with the middle finger, ring finger or little finger.

[0018] As can be seen from the above technical solutions, on the basis of the existing monopolar electrosurgical knife, the present invention assembles a bipolar electrosurgical knife through a connector and a simple bipolar device, without the need to additionally equip a bipolar electrosurgical knife, which greatly saves the cost of surgical instruments; and the bipolar device can be used as forceps, and basically does not change the surgeon's usage habits of the instruments, and its operation is simple and convenient. Brief Description of the Drawings

[0019] Figure 1 is a schematic structural diagram of the present invention. Detailed Embodiments

[0020] The following combines Figure 1 to introduce the present invention in detail. Here, the schematic embodiments of the present invention and the descriptions are used to explain the present invention, but not to limit the present invention.

[0021] The present invention provides a monopolar-to-bipolar electrosurgical knife, which includes a monopolar electrosurgical knife 1. The monopolar electrosurgical knife is an existing pen-shaped electrosurgical knife with electrosection and electrocoagulation hemostasis functions. It also includes a bipolar device 2. The bipolar device is movably connected to the knife head 11 of the monopolar electrosurgical knife through a connector 3. The monopolar electrosurgical knife controls the electrooperation of the bipolar device through the connector, that is, when the electrosection key of the monopolar electrosurgical knife is pressed, the bipolar device performs electrosection operation; when the electrocoagulation key of the monopolar electrosurgical knife is pressed, the bipolar device performs electrocoagulation hemostasis operation. When only a monopolar electrosurgical knife is needed, the knife head can be removed from the connector, and then the monopolar electrosurgical knife can be used for operation, and the bipolar device can also be used as forceps. Thus, it can be seen that the present invention makes clever use of the existing surgical instruments and can quickly convert the monopolar electrosurgical knife into a bipolar electrosurgical knife, greatly saving the cost.

[0022] Specifically, the bipolar device 2 includes two elastic clamping arms 21 that can be clamped together and an arm body 22 formed by the convergence of the two elastic clamping arms. The arm body is electrically connected to the connecting head, so that the two clamping arms can be energized to realize the operation of the bipolar electric knife. During the implementation process, the bipolar device can use the forceps necessary for surgery. The body of the forceps at the fixed end is electrically connected to the knife head through the connecting head. After the two clamping arms at the free end of the forceps are energized, they can be used as the bipolar of the electric knife. It is not only convenient for material selection and operation, but also further reduces the cost.

[0023] As a first preferred method, the connecting head adopts a conductive clip (not shown in the figure). The conductive clip is electrically connected to the arm body, and the clamping head of the conductive clip can clamp the knife head. The conductive clip is an existing device. For example, one side of the conductive clip is connected to the arm body through a wire or directly welded to the arm body, and the clamping head of the conductive clip can clamp the knife head to realize power connection. At the same time, the clamping head can be conveniently removed from the knife head to realize a movable connection. In the case where a bipolar electric knife is not required, the disassembly is fast and convenient.

[0024] As a second preferred method, as Figure 1 , the connecting head adopts a conductive column 31. One end of the conductive column is electrically connected to the arm body, and a conductive hole 32 is opened at the other end of the conductive column. The knife head is inserted into the conductive hole and electrically connected to the conductive column to realize power connection. This method is convenient for processing, and the disassembly and assembly are fast. Preferably, the conductive column can also be directly fixed and formed on the arm body, and the conductive column and the arm body form an integrally formed structure, which is more convenient for processing.

[0025] As a third preferred method, the connecting head is a through hole (not shown in the figure) opened on the arm body. The knife head is inserted into the through hole and electrically connected to the arm body. This method is simpler and has a lower cost. For example, a through hole can be directly opened on the body of the existing forceps to realize the operation of converting a monopolar to a bipolar. To ensure the reliability of the electrical connection, a conductive sleeve (not shown in the figure) can be fixed on the through hole. The knife head is inserted into the conductive sleeve and electrically connected to the arm body, thereby increasing the contact area between the knife head and the conductive sleeve and making the conduction more stable.

[0026] Preferably, an insulating sleeve 4 is sleeved on the arm body and the two elastic clamping arms. The free ends of the two elastic clamping arms both extend out of the insulating sleeve, thereby forming two poles, and are relatively pointed and thin, so as to realize bipolar operation. The design of the insulating sleeve can, on the one hand, facilitate the operator to hold, and on the other hand, avoid burning other parts during operation. The monopolar-to-bipolar electric knife of the present invention can be equipped with only one monopolar electric knife during the operation, which greatly saves the operation cost. Moreover, when the bipolar is not used, the bipolar device can be directly used as the forceps necessary for the operation, without increasing any instrument cost for the operation, and basically does not change the operator's usage habit of the instrument, and can also match various models of monopolar electric knives, with strong adaptability.

[0027] The specific usage method of a monopolar-to-bipolar electrosurgical unit provided by the present invention is as follows:

[0028] (1) Take the monopolar electrosurgical unit and rotate it so that the side with the operation button faces downwards;

[0029] (2) Electrically connect the knife head of the monopolar electrosurgical unit to the bipolar device through a connector; the connector can adopt the above three preferred methods, and the bipolar device can adopt a structure similar to tweezers. In this way, after electrically connecting the connector to the bipolar device, the knife head can be clamped or inserted, thereby realizing the electrical connection between the knife head and the bipolar device.

[0030] (3) Then hold the above-mentioned monopolar electrosurgical unit in the palm of the hand and pinch the bipolar device with the thumb and index finger; during the implementation process, due to the movable connection of the connector, an acute angle is formed between the bipolar device and the monopolar electrosurgical unit, which is convenient for single-handed operation.

[0031] (4) After assembly, since the side of the operation button of the monopolar electrosurgical unit faces downwards, when performing an electrical operation, the coagulation key or cutting key of the operation button can be pressed with the middle finger, ring finger or little finger, thereby realizing the coagulation hemostasis operation or cutting operation, achieving the purpose of single-handed operation.

[0032] As can be seen from the above, the method of the present invention basically does not change the surgeon's usage habit of the instrument, can be operated with one hand, and is simple and convenient to operate.
