Problems solved by technology

When using it, ophthalmic tweezers are generally used to hold the thread plug and send it into the blood vessel. If the force and angle are not well grasped, the nylon thread or silicone head will be deformed, and it will not be able to continue to be used.
In the specific operation, it is necessary to cut a V-shaped incision on the external carotid artery with micro-scissors, and then slowly insert the thread plug through the incision. Gradually blurred, because the step-by-step operation is adopted, the blood flowing out after the incision operation will affect the vision of the thread plug inserted into the incision, increasing the difficulty of plug insertion, which in turn increases the difficulty of modeling and affects the success rate of modeling

Embodiment 1

[0034] refer to figure 1 with figure 2 As shown, an embodiment of a wire bolt of the present invention includes a bolt tube 1 and an insertion rod 2 placed inside the bolt tube 1 , and the insertion rod 2 includes a tip 21 at its end. An accommodating chamber 11 penetrates through the inside of the plug tube 1 along its axial direction, and the insertion rod 2 is placed in the accommodating chamber 11 , and the axial direction of the insertion rod 2 and the axial direction of the plug tube 1 are substantially collinear. The insertion rod 2 placed in the plug tube 1 can move relative to the plug tube 1 along its axial direction, so that the insertion rod 2 can be completely retracted into the inside of the plug tube 1, and the tip 21 at the end of the insertion rod 2 can also be moved from the plug Tube 1 sticks out inside. When the tip 21 protrudes from the inside of the bolt tube 1, and at this time the insertion rod 2 can be relatively fixed with the bolt tube 1 to realiz...

Embodiment 2

[0043] a fixer, see Figure 3-Figure 5 , for adapting to the above-mentioned wire bolt, which includes a main body 3 and an abutment section 4, and the abutment section 4 is connected to the main body 3 through a linkage section. The linkage section is used to adjust the position of the abutment section 4 relative to the main body 3, and the abutment section 4 is used to contact and push the insertion rod 2, so when the main body 3 adjusts the position of the abutment section 4 relative to the main body 3 through the linkage section, the The abutting section 4 that the plunger 2 contacts will adjust the position of the plunger 2 relative to the plug tube 1 , so as to push the tip 21 out of the plug tube 1 .

[0044] The linkage section includes a first elastic member 51 , a first connecting rod 52 and at least one set of locking members 53 , the first connecting rod 52 is connected to the main body 3 through the first elastic member 51 , and the first connecting rod 52 is conn...

Embodiment 3

[0050] a fixer, see Image 6 with Figure 7 Compared with the second embodiment, the difference is that the linkage section includes a second elastic member 61, a second connecting rod 62 and a locking bolt 63, the second connecting rod 62 is connected to the main body 3 through the second elastic member 61, and the second connecting rod The rod 62 is connected to the abutment section 4; the bolt tube 1 is provided with a first communication hole 13 that cooperates with the locking bolt 63, and the abutment section 4 is provided with a group of second communication holes 41 that cooperate with the locking bolt 63; the locking bolt 63 can Through the first communication hole 13 and the second communication hole 41 , preferably, the diameter of the first communication hole 13 is slightly larger than the diameter of the second communication hole 41 and the diameter of the locking bolt 63 .

[0051] When the main body 3 is pressed down, the second connecting rod 62 will press the...

Abstract

The invention discloses a thread bolt, a fixator, a thread bolt operating device and a using method. The thread bolt comprises a bolt tube and an inserting rod movably arranged in the bolt tube, the inserting rod comprises a tip located at the end of the inserting rod; when the thread bolt is in a first state, the tip extends out of the bolt tube and is fixed at the port of the bolt tube, and thethread bolt forms a tip with a puncture function for puncturing; when the thread bolt is in the second state, the tip is located in the bolt tube, and the inserting rod is clamped and fixed to the bolt tube through a blocking part so as to prevent fluid from flowing out of the bolt tube. According to the invention, a blood vessel can be conveniently punctured and the thread bolt can be conveniently inserted into the blood vessel.

Description

technical field [0001] The invention relates to the field of thread bolt operating devices, in particular to a thread bolt, a fixer, a thread bolt operating device and a use method. Background technique [0002] Sutures are usually used to make models simulating human cerebral ischemia (for example, MCAO model). The suture method is currently a routine method in MCAO and other experiments. Nylon threads are mostly used as sutures for modeling. [0003] When the cerebral artery embolism model is made, the thread plug is not directly inserted into the artery in the brain, but is inserted into the anterior cerebral artery through the internal and external carotid artery-the internal carotid artery, thereby blocking the blood supply of the middle cerebral artery. There are following deficiencies when carrying out the above operations: the currently generally used thread bolt is a commercialized monofilament nylon thread, the head is wrapped in silica gel, and the price of the mo...
