Water dropping accessory of bipolar coagulation tweezers for brain department

Abstract

The invention relates to a water dropping accessory of bipolar coagulation tweezers for the brain department. A water dropping accessory device is additionally arranged on a pair of ordinary bipolar coagulation tweezers for the brain department, two P-shaped clamping grooves are clamped to two tweezer legs of the bipolar coagulation tweezers respectively, and two water dropping hoses pass through the P-shaped clamping grooves. The P-shaped clamping grooves are driven to be overlapped or staggered through elastic force of the bipolar coagulation tweezers so as to start or stop water dropping. When the pair of bipolar coagulation tweezers is folded to perform fulguration on tissue, water dropping is started; when the pair of bipolar coagulation tweezers is loosened, water dropping is stopped. The two water dropping hoses are fixed to the bipolar coagulation tweezers through the clamping grooves, and the tail ends of the water dropping hoses are connected with an infusion bottle. The infusion bottle is hung in a high position to generate gravity difference so as to achieve water dropping. The water dropping accessory of the bipolar coagulation tweezers for the brain department has the advantages that electric coagulation eschars are effectively reduced; water dropping can be controlled; a pair of special water dropping bipolar coagulation tweezers does not need to be purchased additionally, and thus medical cost is reduced; the view field of microsurgery is not affected; the water dropping accessory is simple in structure, favorable for mass production, easy and convenient to operate and disposable.

Description

technical field [0001] This work involves a surgical instrument, which is a drip attachment device that can be applied to bipolar coagulation forceps in general brain surgery. It is mainly used in various neurosurgery operations. Background technique [0002] The brain bipolar coagulation forceps currently on the market are mainly used for hemostasis in neurosurgery. Because black eschar is likely to be left between the bipolar electrodes of the electrocoagulation forceps after electrocoagulation, which affects the effect of electrocoagulation, it is necessary for the assistant to closely cooperate with dripping water to reduce the eschar residue. The dripping bipolar coagulation forceps invented in recent years has also been applied in neurosurgery. However, the dripping bipolar coagulation tweezers do not have a dripping switch, and when dripping is not needed, the dripping still keeps on dripping, affecting the operative field. In order to solve the above problems, this...
