Abstract

The invention relates to a soft tissue fixing device with absorbable screws and belongs to the technical field of medical apparatus and instruments. The soft tissue fixing device with the absorbable screws comprises a driving device, a screw pipe and a driving rod, wherein the screw pipe is externally in screw joint with a guide pipe; the guide pipe is internally provided with multiple absorbable screws; thread structures are formed on nailed beams of the absorbable screws and provided with screw lead springs; the multiple absorbable screws are sequentially and serially connected end to end so as to be arranged in the guide pipe with a spiral groove. When in use, a trigger is pulled, so that the driving rod is driven by the driving device to rotate, and furthermore the absorbable screws can be emitted out from the guide pipe one by one during herniorrhaphy under a laparoscope. The soft tissue fixing device with the absorbable screws is especially applicable to the herniorrhaphy under the laparoscope, and has the characteristics of adhesion prevention, and convenience and reliability in operation; the guide pipe is a detachable replacement part, so that the fixing device can be repeatedly used only by replacing the guide pipe.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, and more specifically, the present invention relates to a soft tissue fixation device containing absorbable nails. Background technique [0002] Incisional hernia (incisional hernia) refers to a hernia in which internal organs or tissues in the abdominal cavity protrude from the abdominal incision. It is a common complication of laparotomy. Among them, the incidence of lower abdominal midline incisions is higher, mostly in the abdominal longitudinal incision area, which is seen in the incision Dehiscence, infection, and secondary healing of incisions, a small number of them occurred in the absence of a history of incision dehiscence and appeared a long time after surgery. The incidence rate can reach about 2-11%, and the incidence of incisional hernia after wound infection can reach about 40%. Surgical treatment is the main treatment for abdominal incisional hernias. The current repai...
