DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the utility model clearer, the technical scheme of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope protected by the utility model.

[0027] As Figures 1-3 shown, the utility model provides a novel electrocoagulation hook, including hook body 1, first insulating handle 2 and second insulating handle 3, first insulating handle 2 has the hollow first accommodating cavity 21 of two ends opening, is used to accommodate hook body 1, the first end of hook body 1 and second insulating handle 3 fixed connection, the second end of hook body 1 extends to the outside of first accommodating cavity 21, and with first accommodating cavity 21 rotation cooperation, second insulating handle 3 and first insulating handle 2 are connected through rotating assembly, and the holding part 4 is set up on second insulating handle 3, and the second end of hook body 1 is L type tip 11, and the holding part 4 is parallelly arranged with the vertical section 111 of tip 11.

[0028] Further, the part of hook body 1 between the inner wall surface of first accommodating cavity 21 and the close cooperation and rotation abutment.

[0029] By setting the holding part 4 parallelly arranged with the vertical section 111 of tip 11 on second insulating handle 3, doctors can intuitively judge the direction of tip 11 of hook body 1 through the direction of holding part 4 in the operation process, greatly simplifying the judgment process of doctors in the operation process, reducing the operation failure caused by direction misjudgment, and being able to complete the operation operation more quickly and more accurately. And because of the setting of rotating assembly, second insulating handle 3 can rotate relative to first insulating handle 2, and drive hook body 1 to rotate synchronously, and doctors can adjust the angle of holding part 4 according to the use demand, so as to realize the adjustment of the direction of tip 11 of hook body 1, and improve the flexibility of operation operation.

[0030] As an optional implementation, the rotating assembly comprises a rotating groove 23 and a rotating block 33, the first end of the first insulating handle 2 is provided with a plug-in groove 22, the plug-in groove 22 is provided with an annular rotating groove 23, the second end of the second insulating handle 3 is provided with a plug-in part 32, the plug-in part 32 is plug-in matched with the plug-in groove 22, the plug-in part 32 is provided with an annular rotating block 33, and the rotating block 33 is rotationally matched with the rotating groove 23.

[0031] Further, the plug-in part 32 is an annular plate structure. The plug-in part 32 of the second insulating handle 3 is inserted into the plug-in groove 22 and connected with the first insulating handle 2. Meanwhile, the plug-in part 32 is provided with an annular rotating block 33, which can be matched with the rotating groove 23 to realize the rotating motion.

[0032] The doctor changes the direction of the hook body 1 by holding the holding part 4 of the second insulating handle 3 and applying a rotating force, that is, the rotating force is transmitted to the rotating groove 23 through the plug-in part 32 and the rotating block 33, so that the rotating block 33 rotates in the rotating groove 23. Due to the close cooperation and rotating abutment between the rotating block 33 and the rotating groove 23, the second insulating handle 3 can stably rotate relative to the first insulating handle 2, thereby driving the hook body 1 to adjust the direction.

[0033] As an optional implementation, the rotating block 33 is provided with a friction coating on the rotating abutment surface of the rotating groove 23.

Through the interaction of the first friction coating 24 and the second friction coating 34, the friction between the plug-in groove 22 and the plug-in part 32 and the friction between the rotating groove 23 and the rotating block 33 are increased, so that the doctor can feel obvious resistance when rotating the second insulating handle 3, thereby more easily and stably controlling the speed and angle of rotation, improving the accuracy of the operation. Under the action of no external force, the interaction of the first friction coating 24 and the second friction coating 34 can provide sufficient resistance to prevent the second insulating handle 3 from rotating accidentally, ensuring the safety of the operation.

[0035] The first friction coating 24 and the second friction coating 34 are both made of rubber-based composite material, which is made by adding polymer fibers and aluminum oxide particles in the rubber matrix, and has good wear resistance and appropriate friction coefficient.

[0037] In this way, the contact area between the rotating block 33 and the rotating groove 23 is increased, the stability of the structure is improved, and the friction between the two is also increased to prevent the rotating block 33 from falling out of the rotating groove 23 during rotation.

[0038] As an optional embodiment, a conductive assembly is further included, the conductive assembly includes the first wire 5 and the second wire 6, the second insulating handle 3 has a hollow second accommodating cavity 31 with two open ends for accommodating the hook body 1 and part of the first wire 5; one end of the first wire 5 is electrically connected with the hook body 1, and the other end is electrically connected with one end of the second wire 6 through the electrical rotary joint 7, and the other end of the second wire 6 is electrically connected with the electrocoagulator 8.

[0039] Further, the part of the hook body 1 located in the second accommodating cavity 31 and the part of the first wire 5 located in the second accommodating cavity 31 are in close abutment with the inner wall surface of the second accommodating cavity 31.

[0040] When the electrocoagulator 8 works, the current flows to the electrical rotary joint 7 through the second wire 6, and then is transmitted to the first wire 5 through the electrical rotary joint 7. The first wire 5 transmits the current to the hook body 1, and the hook body 1 performs electrocoagulation treatment on the target tissue. The specific structure of the electrical rotary joint 7 and the specific circuit connection relationship between the hook body 1, the first wire 5, the second wire 6 and the electrocoagulator 8 adopt the prior art, as long as they can realize the function of allowing the first wire 5 and the second wire 6 to remain electrically connected when relatively rotating, and will not be described in detail here.

[0041] As an optional embodiment, the holding part 4 is vertically arranged on the second insulating handle 3, the holding part 4 has a cylindrical structure, and five grooves 41 are arranged on the holding part 4, the grooves 41 are arranged in sequence and spaced apart along the axial direction of the holding part 4, and are respectively matched with the fingers in the holding state.

[0042] Further, the holding part 4 is made of insulating material. The grooves 41 correspond to the thumb, index finger, middle finger, ring finger and little finger from top to bottom, conform to the ergonomic principle, can adapt to the holding position of the doctor's fingers, improve the stability and comfort of holding, and facilitate the doctor to hold and operate.

[0043] As an optional embodiment, the outer wall surface of the holding part 4 is provided with friction protrusions 43.

[0044] Further, the grooves 41 are provided with friction protrusions 43, and the friction protrusions 43 have a hemispherical structure, which further increases the friction of the holding part 4, prevents the holding from being unstable due to hand sweat or glove rotation during the operation of the doctor, and improves the operation stability. The number and arrangement of the friction protrusions 43 can be set according to the use requirements.

[0045] As an optional implementation, the upper end of the holding part 4 extends radially outward to form a limiting part 42.

[0046] Further, the corner of the limiting part 42 is smoothly transitioned.

[0047] The limiting part 42 prevents the doctor's hand from slipping out of the holding part 4 during holding, and also serves as a fulcrum of the doctor's hand, so as to better control the rotation angle and force of the holding part 4.
