Description

Technical Field

[0001] This utility model relates to the field of electrosurgical instrument technology, and in particular to an electrosurgical instrument handle that prevents cables from coming loose. Background Technology

[0002] Electrosurgical products (such as high-frequency electrosurgical units and ultrasonic scalpels) are core equipment in the operating room. Their handles, as key components for human-machine interaction, need to be frequently moved during surgical procedures (e.g., the surgeon holds and adjusts the angle, the assistant passes them, and they coordinate with the operating table's raising / lowering / translation). The area around the operating table is typically densely packed with power cords, signal cables, suction tubes, IV tubing, and other consumables. In this complex environment, the handle cables are easily snagged, pulled laterally, and repeatedly bent, causing the connection between the cable and the handle to loosen or even detach, ultimately leading to circuit breaks and loss of energy / signal conduction. This problem not only interrupts the surgical procedure and prolongs operation time but may also increase the medical risks of tissue damage and bleeding due to sudden interruptions or instability in the electrosurgical energy output.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figures 1-5 As shown, the electrosurgical instrument handle for preventing cable detachment provided in this embodiment includes a lower handle housing 1, an upper handle housing (not shown in the figure), and a partition component 2. The partition component 2 is fixed inside the lower handle housing 1, forming a tortuous wiring path within the lower handle housing 1. The upper handle housing is locked to one side of the lower handle housing 1. Those skilled in the art will understand that, in the electrosurgical instrument handle for preventing cable detachment provided in this embodiment, the cable 3 is engaged in the tortuous wiring path. Through friction between the cable 3 and the partition component 2, the cable 3 can be effectively prevented from detaching from the handle, effectively preventing circuit breakage and failure of energy / signal conduction.

[0023] Furthermore, the partition assembly 2 includes a first partition 21 and a second partition 22; the bottom of the lower housing 1 of the handle is provided with a cable outlet 11; the first partition 21 and the second partition 22 are respectively disposed on both sides of the cable outlet 11, the first partition 21 and the second partition 22 are arranged in parallel and are both fixed to the lower housing 1 of the handle; the distance between the first partition 21 and the second partition 22 is the same as the outer diameter of the cable 3. Those skilled in the art will understand that the cable 3 is snapped between the first partition 21 and the second partition 22, which prevents the cable 3 from shaking.

[0024] Furthermore, the partition assembly also includes a third partition 23 and a fourth partition 26; the third partition 23 is located above the first partition 21; the included angle A between the third partition 23 and the first partition 21 ranges from 70 to 120 degrees; the fourth partition 26 is located at the end of the third partition 23 and bends towards the first partition 21; the included angle B between the fourth partition 26 and the third partition 23 ranges from 68 to 73 degrees; the distance between the fourth partition 26 and the inner wall of the lower housing 1 of the handle is the same as the outer diameter of the cable 3. Those skilled in the art will understand that after the cable 3 is inserted into the first partition 21 and the second partition 22, it bends to the left and then bends upwards to be inserted between the fourth partition 26 and the inner wall of the lower housing 1 of the handle. The cable 3 undergoes two bends, thereby increasing the friction between the cable 3 and the partitions and the lower housing 11 of the handle, and also increasing the risk of the cable 3 being pulled off.

[0025] Furthermore, in this embodiment, the value of A is 72 degrees; the value of B is 70 degrees. Those skilled in the art will understand that by setting the angle when the cable 3 passes through the fourth partition 26 and the first partition 21 and the second partition 22, the risk of it being pulled off can be reduced.

[0026] Furthermore, the partition assembly also includes a fifth partition 25; the fifth partition 25 is fixed above the fourth partition 26; the fifth partition 25 is fixed to the lower housing 11 of the handle; the included angle C between the fifth partition 25 and the fourth partition 26 ranges from 25 to 30 degrees; the distance between the fifth partition 25 and the inner wall of the lower housing 1 of the handle is the same as the outer diameter of the cable 3. Those skilled in the art will understand that this further improves the friction between the cable 3 and the fifth partition 25.

[0027] Furthermore, in this embodiment, the value of C is 28 degrees.

[0028] Furthermore, the partition assembly also includes a sixth partition 24; the sixth partition 24 and the fifth partition 25 are arranged in parallel; the sixth partition 24 is positioned above the fifth partition 25 and is staggered with the fifth partition 25; the sixth partition 24 is fixed to the lower housing 1 of the handle; the distance between the fifth partition 25 and the sixth partition 24 is the same as the outer diameter of the cable 3. Those skilled in the art will understand that the cable 3 undergoes multiple bends between the fifth partition 25 and the sixth partition 24, which further reduces the risk of the cable 3 being pulled out.

[0029] Furthermore, threaded posts 27 are provided near the first partition 21, the fifth partition 25, and the sixth partition 24; the threaded posts 27 are fixed to the lower housing 1 of the handle; the upper housing of the handle is provided with through holes that match the number and position of the threaded posts 27. Those skilled in the art will understand that the upper housing and the lower housing 1 of the handle can be locked together by screws.

[0030] Furthermore, the first partition 21, the second partition 22, the third partition 23, the fourth partition 26, the fifth partition 25, and the sixth partition 24 extend outward from the lower housing 1 of the handle; when the upper housing and the lower housing 1 of the handle are closed, the first partition 21, the second partition 22, the third partition 23, the fourth partition 26, the fifth partition 25, and the sixth partition 24 abut against the inner wall of the upper housing of the handle. Those skilled in the art will understand that the above is a first embodiment of the upper housing of the handle; thus, the partitions, along with the upper housing and the lower housing 1 of the handle, can form a wiring path, allowing the cable 3 to escape from the wiring path inside the handle.

[0031] Furthermore, the upper housing of the handle is fixed with a first partition 21, a second partition 22, a third partition 23, a fourth partition 26, a fifth partition 25, and a sixth partition 24 having the same structure as the lower housing 1 of the handle; the first partition 21, the second partition 22, the third partition 23, the fourth partition 26, the fifth partition 25, and the sixth partition 24 on the upper housing of the handle and the first partition 21, the second partition 22, the third partition 23, the fourth partition 26, the fifth partition 25, and the sixth partition 24 on the lower housing 1 of the handle abut against each other. Those skilled in the art will understand that the above is a second embodiment of the upper housing of the handle; when the upper housing and the lower housing 1 of the handle are closed, a cable 3 passage is formed through the partitions.

[0032] Furthermore, a cover plate is fixed inside the upper housing of the handle; after the upper housing of the handle is closed onto the lower housing 1 of the handle, the cover plate abuts against the first partition 21, the second partition 22, the third partition 23, the fourth partition 26, the fifth partition 25, and the sixth partition 24 on the lower housing 1 of the handle. Those skilled in the art will understand that this is a third embodiment of the upper housing of the handle; it prevents the cable 3 from detaching from the top of the partitions.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
