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 body hydraulic bipolar electrocoagulation, which comprises a bipolar electrocoagulation head, a bipolar electric wire, a water pipe rod, a fiber endoscope, a manual hydraulic fitting, and an electrocoagulation straight plug located on the water pipe rod ; One end of the water pipe rod is connected to the water bag, and the other end is connected to the manual hydraulic fittings; the bipolar electrocoagulation is placed in the steering soft suction device that can maintain negative pressure, and the bipolar electrocoagulation head is opened and closed, and the suction is performed under negative pressure. The target tissue is clamped and electrocoagulated to stop bleeding. The invention changes the traditional rigid mechanical force transmission mode, adopts flexible hydraulic pressure, can pass through straight or curved guides, and operates under the assistance of soft / hard fiber endoscopes and microscopes, without repeatedly adjusting the main body of the suction device and the guide. The space position of the attractor only needs to adjust the position and direction of the head of the attractor, and then control the space position of the head of the bipolar coagulation, which reduces the difficulty of operation and reduces the physical pulling and pulling of the nerves and blood vessels in the deep brain. Compression, reduce perioperative complications.

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...
