Problems solved by technology

It often takes most of the time to adjust the angle of the needle holder and suture needle in the middle, especially for small blood vessels, there is a risk of tearing the blood vessel when the operator's line of sight leaves the main blood vessel during the suture process

Embodiment Construction

[0029] Below in conjunction with accompanying drawing, the present invention will be further described:

[0030] like Figure 1-5 As shown, the blood vessel stapler includes a handle part 1, and one end of the handle part 1 is provided with a C-shaped housing 3, and a telescopic clamp 6 is arranged inside the C-shaped housing 3, and the telescopic clamp 6 is used to clamp The sewing needle 5, the telescopic clamp 6 realizes the expansion and contraction of the telescopic clamp through the sliding button 2, and then realizes the release or clamping of the sewing needle 5, the sewing needle 5 adopts an arc-shaped circular needle, and the middle connection of the sewing needle 5 Suture 4. The inner ring of the C-shaped housing 3 is provided with a cavity for placing the telescopic fixture 6. The inner wall of the front end of the cavity is a gradually narrowing neck 9, and the front end of the telescopic fixture 6 is an enlarged opening. The narrowing mouth is used for fixing a...

Abstract

The invention discloses a blood vessel stitching instrument. The blood vessel stitching instrument comprises a handle part, wherein a C-shaped shell is arranged at one end of the handle part; a telescopic clamp is arranged in the C-shaped shell and used for clamping a suture needle; the telescopic clamp is controlled by a sliding button to be unfolded or folded so as to release or clamp the sutureneedle; the suture needle is a round needle; and the middle of the suture needle is connected with a suture line. The blood vessel stitching instrument provided by the invention is simple in structure; the circular suture needle can be placed at the head end of the telescopic clamp, and the sliding button is pushed, so the telescopic clamp stretches out of or retracts into the cavity of the C-shaped shell, and a blood vessel is punctured in a radian mode when the telescopic clamp stretches out; and a suture needle and a needle holder are completely abandoned, and continuous suture of the round needle to blood vessels can be achieved only through the sliding button, so the operation labor amount of a doctor is reduced, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to a blood vessel suturing device, which belongs to the technical field of surgical suturing. Background technique [0002] A suture needle is an instrument used for suturing various tissues, and it consists of three basic parts, namely a needle point, a needle body and a needle eye. The needle tip is divided into three types according to the shape: round head, triangular head and shovel head; the needle body has three types: nearly round, triangular and shovel-shaped. The eye of a needle is a hole that can be used for lead wires, and it has two kinds of ordinary holes and bomb machine holes. Round needles are divided into 1 / 2, 3 / 8 radians, etc. according to the radian, and those with larger radians are mostly used for deep tissues. Secondly, the common suture needles are all sutures at the very end, so that they can only be sutured once in one direction, and then do a suture cycle. [0003] There are many methods of surgical s...
