Description
Technical Field
[0001] The utility model belongs to the technical field of thoracic surgical instruments, and particularly relates to a rotary safety surgical electric hook. Background Technique
[0002] The electric hook is an indispensable instrument in modern thoracic surgery. Its working principle is to achieve the functions of tissue cutting or hemostasis accurately and efficiently through the high heat effect generated by local high current. With the help of this magical tool, surgeons can perform a series of complex and delicate operations such as vascular dissection, bronchial peeling, and lymph node resection with ease. However, in thoracic surgery, especially when dealing with some special positions, surgeons often need to frequently adjust the angle of the wrist to meet different operation requirements. This high-intensity wrist rotation not only easily causes muscle fatigue and soreness, affecting the surgical efficiency, but also has a long-term adverse impact on the surgeon's career. In addition, when using the electric hook to handle difficult situations such as lymph node metastasis or calcified lymph nodes, due to the narrow gap in the lesion area and extremely limited operating space, the high energy of the electric hook is prone to "accidentally injure" adjacent arteries, resulting in unforeseen bleeding events, increasing the complexity and risk of the operation, and posing a potential threat to the patient's life safety. Therefore, it is necessary to improve the existing thoracic surgical electric hook device. Content of the Utility Model
[0003] The utility model aims at the above problems and provides a rotary safety surgical electric hook that enables surgeons to easily complete various complex surgical operations while maintaining a comfortable wrist posture, improves the efficiency and quality of the operation, can avoid direct damage to surrounding tissues by high-temperature energy, ensures surgical safety, and has high use reliability.
[0004] The technical solution adopted by the utility model is as follows: The rotary safety surgical electric hook includes an electric hook holding handle, and is characterized in that: an electric hook extension rod is arranged at the front end of the electric hook holding handle, the rear part of the electric hook extension rod is detachably connected to the front end of the electric hook holding handle through an electric hook connecting body, and a connecting body locking nut is arranged on the electric hook connecting body; a metal hook head is arranged at the front end of the electric hook extension rod; and, the electric hook extension rod is rotationally connected to the electric hook connecting body, and an electric hook rotation adjustment mechanism is arranged between the electric hook connecting body and the electric hook extension rod; an electrocoagulation switch and an electrosection switch are respectively arranged on the upper side of the electric hook holding handle, a holding depression is arranged on the lower side of the electric hook holding handle, an electric hook power connection head at the rear end of the electric hook extension rod is electrically connected to the circuit structure inside the electric hook holding handle, and a connecting wire is further arranged at the rear end of the electric hook holding handle, and an electrical connection plug is arranged at the end of the connecting wire.
[0005] Inside the electric hook extension rod, there is an electric hook conductive inner core, which is wrapped by an insulating outer layer. One end of the electric hook conductive inner core is connected to the metal hook head, and the other end is connected to the electric hook power connection head. On the insulating outer layer at the rear of the electric hook extension rod, there is also a limit bump for the extension rod. This is to transmit energy to the metal hook head at the front end through the electric hook conductive inner core and use the wrapped insulating outer layer to improve the safety and reliability of the device during use.
[0006] On the surface of the bent section at the root of the metal hook head at the front end of the electric hook extension rod, there is an anti-scalding heat insulation coating. By using the anti-scalding heat insulation coating made of polymer material or ceramic material on the surface of the bent section at the root of the metal hook head, it can avoid the situation that the high-energy metal hook head accidentally injures the adjacent artery due to the narrow gap and limited operating space in the lesion area, resulting in unforeseen bleeding events, effectively reducing the complexity and risk of the operation, and preventing potential threats to the patient's life safety.
[0007] On the lower side of the bent section at the root of the metal hook head at the front end of the electric hook extension rod, there is an anti-scalding heat insulation cushion block. By using the anti-scalding heat insulation cushion block made of polymer material or ceramic material on the lower side of the bent section at the root of the metal hook head, it can avoid the metal hook head accidentally injuring the adjacent artery and effectively reduce the complexity and risk of the operation.
[0008] The electric hook rotation adjustment mechanism includes a rotation adjustment disk rotatably arranged on the electric hook connecting body. The two ends of the rotation axis of the rotation adjustment disk are respectively connected to the electric hook connecting body through the rotation connection seats of the adjustment disk. The rotation adjustment disk penetrates the outer wall of the electric hook connecting body, with half of the adjustment disk outside the connecting body and half inside the connecting body. Moreover, the part of the rotation adjustment disk located inside the cavity of the electric hook connecting body is in contact with the outer wall at the rear of the electric hook extension rod. By rotating the rotation adjustment disk rotatably arranged on the electric hook connecting body, it can drive the electric hook extension rod and the metal hook head at its front end to rotate relative to the electric hook connecting body around the rotation axis, enabling the surgeon to easily complete various complex surgical operations while maintaining a comfortable wrist posture, avoiding muscle fatigue and soreness caused by high-intensity wrist rotation, and effectively improving the efficiency and quality of the operation.
[0009] On the other side of the cavity of the electric hook connecting body, opposite to the rotation adjustment disk, there are two groups of symmetrically arranged electric hook rotation guiding rollers for supporting and guiding the rotation of the electric hook extension rod. The electric hook rotation guiding rollers are respectively rotatably connected to the inner wall of the cavity of the electric hook connecting body through the guiding roller mounting seats. During the process of the rotation adjustment disk driving the electric hook extension rod to rotate, the two groups of electric hook rotation guiding rollers are used to support the force and guide the rotation of the electric hook extension rod.
[0010] Above the rotary adjustment disc of the electric hook rotary adjustment mechanism, an adjustment positioning mechanism is provided. The rotation position of the rotary adjustment disc can be locked through the adjustment positioning mechanism, so as to fix the use angle of the electric hook extension rod and the metal hook head at its front end.
[0011] The adjustment positioning mechanism includes an arc-shaped elastic positioning buckle for the adjustment disc. One end of the elastic positioning buckle for the adjustment disc is connected to the outer wall of the electric hook connecting body through a buckle hinge seat, and the other end of the elastic positioning buckle for the adjustment disc is detachably connected to a buckle block provided on the outer wall of the electric hook connecting body. And there is an operation space for the adjustment disc between the un-locked elastic positioning buckle for the adjustment disc and the rotary adjustment disc. When it is necessary to fix the use angle of the electric hook extension rod and the metal hook head at its front end, press down the elastic positioning buckle for the adjustment disc to make the end of the elastic positioning buckle for the adjustment disc engage with the buckle block, so as to lock the adjustment disc by the extrusion and friction between the elastic positioning buckle for the adjustment disc and the rotary adjustment disc. At the same time, in the state where the elastic positioning buckle for the adjustment disc is not locked, the reserved operation space for the adjustment disc facilitates the single-handed operation of the rotary adjustment disc.
[0012] On the outer circumferential surface of the rotary adjustment disc, an adjustment disc friction flange is provided. Correspondingly, on the outer wall of the electric hook extension rod, at the position in contact with the adjustment disc, a friction flange mating surface is provided. By using the cooperation between the adjustment disc friction flange on the outer circumferential surface of the rotary adjustment disc and the friction flange mating surface on the electric hook extension rod, the driving force of the rotary adjustment disc on the electric hook extension rod can be improved to ensure the reliability of the device operation.
[0013] The bending angle of the bending section at the root of the metal hook head is between 100 degrees and 140 degrees. This makes the device easier to operate and improves the use flexibility.

[0030] When the rotating safety surgical electro-hook is in use, first, according to the specific surgical needs, select an electro-hook extension rod 4 (including the metal hook head 5 at the front end) with an appropriate length or shape, and rotatably insert the rear end of the electro-hook extension rod 4 into the electro-hook connector 6 through the extension rod connection jack 15; then, through the handle connection socket 19, plug and connect the electro-hook connector 6 and the electro-hook extension rod 4 to the front end of the electro-hook holding handle 1, and electrically connect the electro-hook power connection head 20 at the rear end of the electro-hook extension rod 4 to the circuit structure inside the electro-hook holding handle 1, and use the connector locking nut 7 to lock the connection between the electro-hook connector 6 and the electro-hook holding handle 1. Then, connect the electrical connection plug 11 at the end of the connection wire 10 to a dedicated power source to provide the required energy for the surgical electro-hook.
[0031] During the process of using the electro-hook to cut or stop bleeding of tissues, the electro-hook extension rod 4 and its front-end metal hook head 5 can be driven to rotate relative to the electro-hook connector 6 around the rotation axis by rotating the rotation adjustment disk 13 provided on the electro-hook connector 6, so that the surgeon can complete various complex surgical operations while maintaining a comfortable wrist posture, effectively improving the efficiency and quality of the surgery. And when it is necessary to fix the use angle of the electro-hook extension rod 4 and its front-end metal hook head 5, the adjustment disk elastic positioning buckle 16 can be pressed down with one hand, so that the end of the adjustment disk elastic positioning buckle 16 is engaged with the buckle block 17, thereby locking the rotation adjustment disk 13. At the same time, the anti-scalding heat-insulating coating 29 or anti-scalding heat-insulating spacer 30 made of polymer material or ceramic material provided at the bent section at the root of the metal hook head 5 at the front end of the electro-hook extension rod 4 can avoid the situation of accidentally injuring the adjacent artery due to the narrow gap in the lesion area and limited operating space, effectively reducing the complexity and risk of the surgery.
