[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0020] Example

[0021] See Figures 1 to 5It is shown that the structure, proportion, size and the like shown in the drawings attached to the present specification are only used to cooperate with the content disclosed in the specification, to be understood and read by those skilled in the art, and are not used to limit the implementation of the utility model, so they do not have technical significance. Any modification of structure, change of proportion relationship or adjustment of size, without affecting the effect and purpose of the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, if there are terms such as "upper", "lower", "left", "right", "middle" and "one" in the specification, they are only for the convenience of clear description, and not for limiting the scope of the utility model, and the change or adjustment of the relative relationship is also considered as the scope of the utility model.

[0022] The electrode forceps head with ceramic spacer sleeve in the embodiment comprises a positive electrode forceps head 1 and a negative electrode forceps head 2, the positive electrode forceps head 1 cooperates with the negative electrode forceps head 2, the positive electrode forceps head 1 and the negative electrode forceps head 2 are each sleeved with a forceps head spacer sleeve 3, a plurality of spacer sleeve protrusions 31 are arranged on the forceps head spacer sleeve 3, spacer sleeve grooves 32 are formed between adjacent spacer sleeve protrusions 31, spacer sleeve through holes 33 are arranged at the bottom of the spacer sleeve grooves 32, and the spacer sleeve protrusions 31 on the two forceps head spacer sleeves 3 are symmetrically or staggeredly arranged.

[0023] The forceps head spacer 4 is arranged between the positive electrode forceps head 1 and the negative electrode forceps head 2, the negative electrode forceps head 2 is installed on the forceps seat 5, the positive electrode forceps head 1 is connected with the pull rod 6, the forceps seat 5 is arranged outside the forceps seat spacer 7, and the pull rod 6 is arranged inside the pull rod spacer 8.

[0024] Specifically, the electrode forceps head with ceramic spacer sleeve is a coagulation medical device in which the positive electrode forceps head 1 and the negative electrode forceps head 2 of a conventional bipolar forceps head are respectively wrapped with forceps head spacer sleeves 3, the positive electrode forceps head 1 and the negative electrode forceps head 2 are metal forceps heads with electric conduction function, in use, the positive electrode forceps head 1 can be pushed and pulled through the pull rod 6, and then the opening and closing control of the positive electrode forceps head 1 and the negative electrode forceps head 2 can be realized, and the connection relationship between the pull rod 6 and the positive electrode forceps head 1 is the prior art.

[0025] The electrode forceps head with ceramic spacer sleeve wraps the positive electrode forceps head 1 and the negative electrode forceps head 2 made of metal with forceps head spacer sleeves 3, and sets spacer sleeve protrusions 31 on the forceps head spacer sleeves 3, so that when the human body tissue is clamped, the spacer sleeve protrusions 31 on the two forceps head spacer sleeves 3 can be in contact with the human body tissue, the contact area between the positive electrode forceps head 1 and the negative electrode forceps head 2 and the human body tissue can be reduced, and the adhesion between the positive electrode forceps head 1 and the negative electrode forceps head 2 and the human body tissue can be avoided.

[0026] When the two sleeve protrusions 31 clamp the human tissue, the human tissue can be embedded into the sleeve groove 32, and the positive electrode jaw 1 and the negative electrode jaw 2 can be exposed outside through the sleeve through hole 33 due to the bottom of the sleeve groove 32 being provided with the sleeve through hole 33. When the human tissue is clamped and coagulated, the intermittent and high-frequency sparking of the sleeve groove 32 is used to realize coagulation. Since the positive electrode jaw 1 and the negative electrode jaw 2 made of metal do not actually contact the human tissue, the jaw sleeve 3 layer contacting the human tissue is first made of an inert material and has good heat resistance, so that adhesion is avoided.

[0027] The jaw sleeve 3 wrapped outside the positive electrode jaw 1 and the negative electrode jaw 2 can play a role of heat preservation and heat insulation for the positive electrode jaw 1 and the negative electrode jaw 2, so that the heat generated by the positive electrode jaw 1 and the negative electrode jaw 2 during coagulation of the human tissue is prevented from being dissipated to affect the normal human tissue.
