[0052] Among them, the lower hole (4) of the sleeve (3) is 0° to the horizontal plane; the needle point (7) is a cone structure; the upper part of the core cap (5) is a hollow cylinder structure, and the core cap (5) The lower part is a hollow circular platform structure; the upper par...
Embodiment 2
[0063] Such as Figure 10 As shown, a device for assisting surgical suture entry and exit, including an outer sleeve, a needle core and a guide needle, the outer sleeve includes a sleeve cap (2) and a hollow sleeve (3); the upper hole of the sleeve cap (2) (1) is connected up and down with the lower hole (4) of the casing (3); the lower hole (4) of the casing (3) is 45° to the horizontal plane. Other structures are with embodiment 1.
Embodiment 3
[0065] Such as Figure 11 As shown, an auxiliary surgical suture thread entry and exit device includes an outer sleeve, a needle core and a guide needle. The needle core includes a needle core cap (5), a needle core body (6) and a needle point (7); the needle point (7) is The cross-section is a cylindrical structure with a slope of 45 degrees. Other structures are with embodiment 1.
[0066] Such as Figure 1~9 As shown, the simple and safe new method under direct vision is used to replace the old method which is cumbersome and easy to accidentally injure patients and operators under blind vision; that is, insert the needle core into the outer cannula and pierce the ribs of the chest wall. The gap enters the thoracic cavity; after removing the needle core, insert the needle bar and introduce the surgical suture into the thoracic cavity; draw the needle exit point on the opposite side of the incision to insert the outer cannula and the guide needle, and put the surgical sutur...
