Problems solved by technology

[0003] (1) When the suction device and the ring curette are used together, both hands are required, which puts forward higher requirements for the coordination of the surgeon's hands
[0004] (2) It can only work in a straight working channel, and it is necessary to constantly adjust the spatial position of the suction device and the ring curette at the same time
[0005] (3) During microsurgery, due to the obstruction of the suction device and the ring curette itself, the acquisition of light and field of view is affected, and in some cases, it is operated blindly by hand feeling
[0006] (4) During endoscopic surgery, the endoscope holder, aspirator holder and ring curette need to be operated by three hands, which is more difficult to coordinate
[0007] (5) Some hospitals have pneumatic arms, but the equipment is expensive and difficult to popularize
[0008] (6) After passing through a curved channel, or after a minimally invasive small-diameter medical device turns, traditional microscopic instruments cannot be used effectively

Embodiment 1

[0036] Such as figure 1 As shown, the soft hydraulic tissue forceps includes tissue forceps head 1, water pipe rod fixed wing 2, water pipe rod 3, endoscope position bracket 4, tissue forceps straight mouth plug 5, soft / hard fiber endoscope 6, index finger and middle finger holding Position 7, thumb holding position 8, the opening and closing of the index finger and middle finger relative to the thumb, through hydraulic pressure, control the expansion and contraction of the water bladder 10, and then control the closing and opening of the head of the tissue forceps; the manual hydraulic fitting 9, the water pipe The rod 3 and the soft / hard fiber endoscope 6 pass through the corresponding apertures of the tissue forceps straight plug 5 .

[0037] Such as figure 2 As shown, after the combination of the hydraulic tissue forceps and the soft / hard fiber endoscope, they are put into the steering soft suction device together, and the steering control handle 16 of the steering soft ...

Embodiment 2

[0045] When operating under a neurosurgery microscope, the present invention can be removed figure 1 The water pipe pole fixed wing 2 and the endoscope position support 4, the tissue forceps straight mouth plug 5 and the soft / hard fiber endoscope 6 parts in the microscope field of view are assisted, and the tissue forceps head of the present invention is stretched into the operation field Scrape, separate, and grasp the target tissue at the corresponding position.

[0046] 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; When passing through the straight channel introducer, the fiber endoscope can be soft or rigid fiber endoscope.

Abstract

The invention discloses soft hydraulic tissue forceps. The soft hydraulic tissue forceps comprise a tissue forceps head part with a water bag, a water tube rod and a hydraulic accessory, one end of the water tube rod is connected with the water bag, the other end of the water tube rod is connected with the hydraulic accessory, and the hydraulic accessory controls the tissue forceps head part to beclosed and opened by controlling out-stretching and back-drawing of the water bag. The tissue forceps and a fiberoptic endoscope are put into a minimally invasive steering soft aspirator with negative pressure after being combined, and the aspirator is put into a guiding device; an upper spatula arm and a lower spatula arm are opened and closed to conduct forceps scraping or separation by utilizing the hydraulic accessory for controlling out-stretching and back-drawing of the water bag. The soft hydraulic tissue forceps can be put into the minimally invasive steering soft aspirator and can pass through rigid small-caliber straight channels and arc channels after being deformed, and thus the injuries to the brain parenchyma, the nerves, the blood vessels and other tissue are reduced.

Description

technical field [0001] The invention relates to tissue forceps in neurosurgical microsurgery and endoscopic surgery, in particular to a soft hydraulic tissue forceps. Background technique [0002] In endoscopic surgery and microsurgery in neurosurgery deep brain, deep spinal canal, etc., it is necessary to scrape, separate, and suck away small pieces of diseased tissues such as tumors and hematomas. However, the current tools have the following disadvantages: [0003] (1) When the suction device and the ring curette are used together, both hands are required, which puts forward higher requirements on the coordination of the surgeon's hands. [0004] (2) It can only work in a straight working channel, and it is necessary to constantly adjust the spatial position of the suction device and the ring curette at the same time. [0005] (3) During microsurgery, due to the obstruction of the suction device and the ring curette itself, the acquisition of light and field of view is ...
