Description

Technical Field

[0001] This utility model belongs to the field of surgical electrode technology, specifically relating to a closing and locking structure suitable for surgical electrode forceps. Background Technology

[0002] Surgical electrodes are important medical devices. Typically made of conductive materials, they can be placed on or inside the patient's body to measure and record various bioelectrical signals, such as electrocardiograms (ECGs), electroencephalograms (EEGs), and electromyograms (EMGs). They can also be used in electrosurgical procedures, such as electrocautery and electrocoagulation, using high-frequency current to generate heat to cut tissue or coagulate blood vessels. A surgical electrode typically includes an electrode working end, an insulating sheath, a handle, a scalpel shaft, and a forceps head.

[0003] Most existing surgical electrode forceps adopt a double-acting forceps design, which is inconvenient to operate during surgery. After closing, the two forceps are misaligned, and the clamping pressure is unstable. Summary of the Invention

[0004] This invention provides a closing and locking structure suitable for surgical electrode forceps, which aims to solve the problems of existing surgical electrode forceps, which mostly adopt a double-acting forceps design, making operation inconvenient during surgery, and causing misalignment of the two forceps after closing, resulting in unstable clamping pressure.

[0005] This utility model embodiment provides a closing and locking structure suitable for surgical electrode forceps, including a lower forceps head, an upper forceps head above the lower forceps head, a rotating rod at the tail of the upper forceps head, the rotating rod having an L-shaped structure, a central shaft on both sides of one end of the rotating rod, the rotating rod being disposed in a cavity at the tail of the lower forceps head, the rotating rod being rotatably connected to the tail of the lower forceps head, a movable plate being installed on the outer side of the tail of the lower forceps head, a through opening being reserved on one side of the movable plate, a through movable groove being reserved at the tail of the lower forceps head, and the end of the rotating rod away from the upper forceps head passing through the movable groove and the through opening in sequence.

[0006] By adopting the above technical solution, the movable plate is pulled left and right, which drives the rotating rod to rotate around the central axis. The rotating rod drives the upper clamp head to rotate, thereby moving the upper clamp head closer to or away from the lower clamp head. The size of the opening between the upper and lower clamp heads can be controlled by controlling the movement distance of the movable plate. The operation is convenient, the clamping pressure is stable, and the practicality of the surgical electrode is greatly improved.

[0007] Furthermore, a knife bar is fixedly connected to the right end of the lower clamp head.

[0008] By adopting the above technical solution, it is ensured that the electrode is installed on the handle of the surgical electrode.

[0009] Furthermore, a sliding groove is reserved on the lower wall surface of the lower jaw head, the upper wall surface of the movable piece is attached to the sliding groove, and the movable piece is slidably disposed on the sliding groove.

[0010] By adopting the above technical solution, it is ensured that the movable piece can slide close to the lower jaw, while preventing the movable piece from moving or misaligning.

[0011] Furthermore, a clearance groove is reserved between the lower end of the lower jaw head and the lower end of the inside of the tool bar. The clearance groove is connected to the sliding groove, and the movable piece is adapted to the clearance groove.

[0012] By adopting the above technical solution, we can ensure that the moving pieces have enough room to move, while also limiting the movement of the moving pieces.

[0013] Furthermore, the rotating rod has an L-shaped structure.

[0014] By adopting the above technical solution, the connection between the upper jaw and the movable plate is facilitated, ensuring that the upper jaw on the rotating rod can be rotated through the movable plate.

[0015] Furthermore, a linkage rod is fixedly connected to one end of the movable piece that is located in the clearance groove.

[0016] By adopting the above technical solution, the movable plate is connected to the handle of the surgical electrode through a linkage rod, ensuring that the movement of the linkage rod is controlled by the handle of the surgical electrode, thereby controlling the movement of the movable plate and thus controlling the opening size of the upper forceps head.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention utilizes a movable plate that can be pulled left or right. The movable plate causes a rotating rod to rotate around a central axis, which in turn causes the upper clamping head to rotate. This allows the upper clamping head to move closer to or further away from the lower clamping head. By controlling the movement distance of the movable plate, the size of the opening between the upper and lower clamping heads can be controlled. This design is convenient to operate, provides stable clamping pressure, and greatly improves the practicality of the surgical electrode.

[0019] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description
