Minimally invasive fascial closer

Abstract

The invention relates to a minimally invasive fascial closer. The fascial closer comprises a columnar casing, a pull rod, a columnar drive handle, a suture sending needle as well as two turnover support plate bodies connected to the lower end of the casing and the lower end of the pull rod, each turnover support plate body comprises a mounting part and a clamping part, a cylindrical hinge pin holeand an arc slide hole are formed in the mounting part of each turnover support plate body, a silicone block is inlaid in the clamping part of each turnover support plate body and located in a throughhole in the clamping part, a storage groove is formed in the lower surface of the clamping part of each turnover support plate body, a protective cap is connected in each storage groove through a first elastic strip and a second elastic strip, after the suture sending needle penetrates through the silicone blocks on the turnover support plate bodies, the point of the suture sending needle props in the protective caps, damage of the point to organs of a patient is avoided, and meanwhile, the protective caps cannot separate from the suture sending needles in the pushing process and are safer and reliable.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a minimally invasive fascia closure device. Background technique [0002] For minimally invasive surgery, the perforation on the human body after the operation is generally sutured on the outer epidermis. Due to the small diameter of the perforation, there is no way to suture the inner part, resulting in slow and weak healing of the perforation. The fascia closure device is used to suture the perforation in minimally invasive surgery. When the fascia closure device is used for perforation and suture, the needle tip of the thread feeding needle penetrates the abdominal wall and easily stabs the internal organs of the abdominal wall when the thread is fed through the abdominal wall. Because the thread feeding process is difficult to control, the needle tip of the thread feeding needle may even accidentally pierce the internal organs, which is very dangerous and will cause s...

Problems solved by technology

But, because the thread-feeding needle 3 extends obliquely along the thread-feeding channel 4, the needle point of the thread-feeding needle 3 must be obliquely supported on the inner side of the protective cover 5-1, and pushes the protective cover 5-1 obliquely downward to make the elastic member When 5-2 is deformed, since the elastic member 5-2 is an elastic sleeve, when the protective cover 5-1 pulls the elastic member 5-2 obliquely downward, the deformation around the elastic member 5-2 is inconsistent, which will inevitably lead to the deformation of the protective cover 5-2. -1 is tilted due to uneven force, then the needle point of the thread feeding needle 3 will be unstable against the protective cover 5-1, and even slippage will occur so that the needle point of the thread feeding needle 3 deviates from the protective cover 5-1, thereby There is a risk of piercing the elastic member 5-2, and there is a risk of injuring the internal organs of the patient. Therefore, this solution also has potential safety hazards
