Description
Technical field
This utility model relates to a kind of cutting closed-system binding clip, belongs to Electrosurgical instrument technical field.
Background technology
Cutting closed-system, by the physical compression of apparatus and the sintering of high frequency stream, merges the collagen protein of blood vessel wall and fibrinolysis degeneration, makes vessel sealing.After blood vessel is closed, can directly cut off zonula occludens, greatly shorten operating time, reduce hemorrhage, operation risk is down to minimum, because its superiority and reliability of pricking with respect to traditional toe-in is widely used in surgical operation.At present, in order to there is short circuit phenomenon closing up under state in two binding clips preventing from cutting closed-system binding clip, its a kind of structure is the upper ceramic block that directly bonds on a slice binding clip therein, this ceramic block has met requirement high temperature resistant and insulation, but owing to being relatively difficult to control in metal and ceramic adhesion technique,, therefore there is certain risk in using in the phenomenon that still exists projection to drop in actual use.Another kind of structure is that high-temperature resistance plastice is directly generated to anti-short circuit projection on binding clip, this projection has solved the problem coming off, but the tolerable temperature of high-temperature resistance plastice is limited, in operation process, unavoidably can discharge by flashing, and the temperature of spark discharge position is considerably beyond the tolerable temperature of high temperature plastics, this projection is likely melted, so this structure is also to have certain risk.
Summary of the invention
The purpose of this utility model is to provide a kind of good insulation preformance, and tolerable temperature is high, can prevent that short circuit from can prevent that again ceramic projection from dropping, and can improve the cutting closed-system binding clip of safety in utilization.
This utility model is that the technical scheme achieving the above object is: a kind of cutting closed-system binding clip, comprise the first caliper and the second caliper that are hinged on axostylus axostyle, the first described caliper comprises the first binding clip pedestal, the first insulator and the first stainless steel substrates that are connected successively; The second described caliper comprises the second binding clip pedestal, the second insulator and the second stainless steel substrates that are connected successively, the first stainless steel substrates is connected with wire respectively with the second stainless steel substrates, it is characterized in that: the side interlocking that described the second insulator is positioned at the second stainless steel substrates has three above ceramic projections, and each ceramic projection passes the through hole that the second stainless steel substrates is corresponding.
This utility model adopts multiple resistant to elevated temperatures ceramic projections interlocking at the second insulator, in the injection moulding connection procedure of the second stainless steel substrates and the second insulator, ceramic part projection is coated and is fixed by the second insulator, make ceramic projection and the second insulation physical ability form an overall structure, after the second insulator is connected with the second stainless steel substrates, block ceramic projection by the second stainless steel substrates, the phenomenon of having avoided ceramic projection in use to drop.Because ceramic projection bearing temperature is up to 2000 ℃, do not have any variation even if arc discharge occurs the ceramic projection on binding clip in discharge process yet, can normally work, while having avoided devices work, the phenomenon of burning ceramic projection due to arc discharge, can meet requirement high temperature resistant and insulation, guarantee that apparatus safety is used normally.This utility model is in use cutting closed-system process, in the time that the first binding clip and the second binding clip close up, just make can form certain gap between the first stainless steel substrates of the first binding clip and the second stainless steel substrates of the second binding clip by ceramic projection, effectively prevent the short circuit phenomenon between two binding clips, the power that cutting closer output can not occur is applied to the phenomenon in tissue, has improved the safety using.
