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 a soft hydraulic tissue forceps, which comprises a tissue forceps head with a water bladder, a water pipe rod and hydraulic fittings, one end of the water pipe rod is connected to the water bladder, and the other end is connected to the hydraulic fittings, and the hydraulic fittings control the expansion and contraction of the water bag. Then control the closing and opening of the tissue forceps head. After the tissue forceps and the fiberoptic endoscope are combined, they are placed into a minimally invasive steering soft suction device with negative pressure, and the suction device is placed into the guide; the upper spatula arm and the lower spatula arm control the flow of the water bladder through hydraulic fittings. Telescoping to open and close for scraping or separation. The present invention can be placed in a minimally invasive steering soft body suction device, and can pass through rigid small-diameter straight channels and arc-shaped channels after deformation, thereby reducing damage to brain parenchyma, nerves, blood vessels and other tissues.

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 ...
