Embodiment 1

[0032] Such as figure 1 , figure 2 As shown, when the bipolar electrocoagulation of the present invention is inserted into a steering soft suction device, the bipolar electrocoagulation includes a bipolar electrocoagulation head 1, a water pipe rod fixed wing 2, a water pipe rod 3, an endoscope position bracket 4, and an electrocoagulation head. Coagulation mouth plug 5, soft / hard fiber endoscope 6, index finger and middle finger holding place 7, thumb holding place 8, bipolar electric wire 9 and manual hydraulic fitting 10. Among them, the opening and closing of the index finger and middle finger relative to the thumb control the directional expansion and contraction of the water bag through hydraulic pressure, that is, the opening of the index finger and middle finger relative to the thumb corresponds to the contraction of the water bag, and then corresponds to the closing of the bipolar arm; The closing of the middle finger relative to the thumb corresponds to the stretch...

Embodiment 2

[0044] When operating under a neurosurgery microscope, the present invention can be removed figure 1 Water pipe rod fixed wing 2 and endoscope position support 4, electrocoagulation straight mouth plug 5 and software / hard fiber endoscope 6 parts in the microscope field of view, the bipolar electrocoagulation head of the present invention is stretched into The target tissue is clamped and electrocoagulated to stop bleeding at the corresponding position of the surgical field. Open the upper and lower electrodes of the bipolar coagulation head, and observe the hemostatic effect of the electrocoagulation. If the hemostatic effect is not good, the above steps can be repeated until the hemostasis is complete and the effect is satisfactory.

[0045] The turning soft suction device in the above two embodiments can pass through a straight channel or an arc channel guide. When the turning soft suction device passes through the arc guide, the fiber endoscope adopts a soft fiber endoscope...

Abstract

The invention discloses a minimally invasive soft hydraulic bipolar electrocoagulator. The minimally invasive soft hydraulic bipolar electrocoagulator comprises a bipolar electrocoagulator head, a bipolar wire, a water tube rod, a fiberoptic endoscope, a manually-controlled hydraulic accessory and an electrocoagulator straight apertural plug which is located on the water tube rod; one end of the water tube rod is connected with a water bag, and the other end of the water tube rod is connected with the manually-controlled hydraulic accessory; the bipolar electrocoagulator is put into a steeringsoft aspirator capable of maintaining negative pressure,, and the bipolar electrocoagulator head is opened and closed to clamp target tissue and conduct electrocoagulation hemostasis under negative-pressure aspiration. According to the minimally invasive soft hydraulic bipolar electrocoagulator, a traditional hard mechanical force conduction mode is changed, flexible hydraulic pressure is adopted, the electrocoagulator can penetrate through a straight or arc guiding apparatus, and is operated under the assistance of the soft / hard fiberoptic endoscope and a microscope, the spatial positions ofa main aspirator body and the guiding apparatus do not need to be repeatedly adjusted, only the position and direction of the head of the aspirator need to be adjusted, in this way, the spatial position of the bipolar electrocoagulator head is controlled, the operation difficulty is lowered, physical traction and compression on the nerves, blood vessels and other tissue of the deep brain part arereduced, and complications in a perioperative period are reduced.

Description

technical field [0001] The invention relates to electrocoagulation of medical instruments in minimally invasive neurosurgery, in particular to a minimally invasive soft body hydraulic bipolar electrocoagulation. Background technique [0002] Blood vessel bleeding and oozing of brain tissue and tumor tissue in neurosurgery are relatively common, which require the use of bipolar coagulation for hemostasis. Especially in neurosurgery under the microscope and endoscope, the operation space is narrow, the introducer is narrow and long, the traditional bipolar coagulation length is long, the arm may block the line of sight, and the clamping action is difficult to complete, requiring a large movement space . At the same time, doctors need to frequently replace suction devices, bipolar coagulation, micro scissors and other instruments during the operation. [0003] Doctors in neurosurgery and other departments have discovered some other shortcomings of existing bipolar coagulation...
