Medical patch fixing pin capable of automatically bending and fixing

Abstract

The invention discloses a medical patch fixing pin capable of automatically bending and fixing and belongs to the field of medical devices. The medical patch fixing pin disclosed by the invention comprises an implanting part and a bending part; the bending part is arranged at the tail of the implanting part; the bending part is provided with at least two bending arms; the bending arms which are adjacent in a circumferential direction are connected together by a connecting structure in a way of being close to the center; and the bending arms have bending stresses for automatically stretching and bending outwards after the connecting structure is disconnected or separated. By adopting the medical patch fixing pin, the connecting structure between the adjacent bending arms is disconnected orstripped by virtue of a machine in a fixing pin shooting process, so that the bending arms bend to fasten a medical patch, and the medical patch is stably fixed together with human tissue; moreover, the fixing pin with the structure is convenient to continuously shoot by virtue of the machine, so that the problem that an existing medical patch fixing pin is difficult to continuously shoot is solved, surgical operations are further facilitated, the operation time is shortened, and meanwhile, the long-term monopoly of foreign countries on the medical patch fixing pin is broken.

Description

technical field [0001] The invention relates to a medical patch fixing nail, in particular to an automatic bending and fixing medical patch fixing nail. Background technique [0002] With the continuous development of material medicine, more and more new materials have entered the medical field as biomedical materials to repair defects in various parts of the human body. Medical mesh is a kind of human tissue repair material, which is widely used in general surgery, mainly for the repair of various hernias, such as inguinal hernia and incisional hernia. Due to the particularity of the hernia site, the patch needs to have strong tensile strength without losing softness, and the patch also needs to have an appropriate shape according to the position of the repaired tissue, so as to be stably fixed on the human tissue. [0003] The fixation of the mesh in the human tissue is the key to the hernia repair operation, and its fixation effect directly affects the success of the ope...

Problems solved by technology

However, due to its structural characteristics, during use, it is necessary to use an implant tool with two clamping arms, and use the two clamping arms of the tool to clamp the two fork arms of the fixing nail to provide sufficient support for the two fork arms. Rigid support; and precisely because of the particularity of its operation, it is necessary to take a fixed clip one by one during operation, which is not conducive to the continuous firing and fixing of the instrument
