Description

Minimally invasive fascia closer

Technical Field

The utility model relates to the technical field of medical equipment, in particular to minimally invasive fascia closer.

Background

For minimally invasive surgery, the perforation on a human body after the surgery is generally sewn on the outer skin, the perforation is slowly healed and is not firm due to the small caliber of the perforation and no way of sewing the inside, therefore, a fascia closer is gradually adopted to sew the perforation of the minimally invasive surgery, when the fascia closer performs perforation and sewing, the needle point of a thread feeding needle penetrates through the abdominal wall and then easily punctures viscera inside the abdominal wall, and because the thread feeding process is difficult to control, the needle point of the thread feeding needle even accidentally punctures the viscera, so that the minimally invasive surgery is very dangerous and can cause secondary injury to a patient;

in the prior art, patent No. CN201611024846.4 (minimally invasive fascia closer) provides a protective cover 5-1 and an elastic member 5-2 connected thereto, and when the thread feeding needle 3 penetrates out of the thread feeding channel 4, the needle tip of the needle is pressed against the inner side surface of the protective cover 5-1, thereby preventing the needle tip of the thread feeding needle 3 from pricking and puncturing the internal organs of the patient. However, since the thread feeding needle 3 is obliquely inserted along the thread feeding channel 4, when the needle point of the thread feeding needle 3 is inevitably obliquely pressed against the inner side surface of the protective cover 5-1 and the protective cover 5-1 is obliquely pushed downwards to deform the elastic member 5-2, since the elastic member 5-2 is an elastic sleeve, when the protective cover 5-1 obliquely pulls the elastic member 5-2 downwards, the deformation amount around the elastic member 5-2 is inconsistent, so that the protective cover 5-1 is inevitably stressed unevenly to be inclined, the needle point of the thread feeding needle 3 is unstably pressed against the protective cover 5-1, even slides to make the needle point of the thread feeding needle 3 deviate from the protective cover 5-1, so that the thread feeding needle has a risk of puncturing the elastic member 5-2 and further injuring internal organs of a patient, and therefore, the scheme also has a potential safety hazard.
