With-needle anorectum stomach-intestine anastomat with movable head capable of absorbing biological nails

Abstract

The invention discloses a with-needle anorectum stomach-intestine anastomat with movable head capable of absorbing biological nails. The with-needle anorectum stomach-intestine anastomat with the movable head capable of absorbing the biological nails comprises a coincided-cutting component, a cocking handle component, a nail abutting seat component, and a lead screw component penetrating through the coincided-cutting component. The nail abutting seat component is provided with a movable shaft, an nail abutting seat, a clamping spring tube and a cutter cushion ring. The coincided-cutting component comprises a ring-shaped cutter, a nail cabin sleeve, a nail push piece and a nail cabin fixed at the front end of the nail cabin sleeve. The head end of the nail push piece is fixedly provided with a plurality of organization penetrating needles, a plurality of coincided nails made of biodegradable materials are arranged in the nail cabin, the plurality of coincided nails are installed on the organization penetrating needles in a sleeved mode, and needle heads of the organization penetrating needles are exposed out of the coincided nails. A pressing cap capable of clamping and fixing the coincided nails is arranged at the position, corresponding to the plurality of coincided nails, of the nail abutting seat, and the pressing cap is also made of the biodegradable materials. A swing limit mechanism capable of enabling the nail abutting component to have a plurality of fixing swinging angles is arranged between the movable shaft and the clamping spring tube. The nail abutting component of the with-needle anorectum stomach-intestine anastomat with the movable head capable of absorbing the biological nails can be conveniently disassembled to be cleaned, can swing, and can enter conveniently and be taken out conveniently. The coincided nails of the with-needle anorectum stomach-intestine anastomat with the movable head capable of absorbing the biological nails can be degraded in a human body, and the phenomenon that the coincided nails can be prevented from being detained in the human body so that an operation sequela is caused can be avoided.

Description

technical field [0001] The invention relates to an anorectal and gastrointestinal stapler with a movable head absorbable bio-nail with a needle, which belongs to the field of medical equipment. Background technique [0002] At present, titanium nails and stainless steel nails are used in surgical operations for anorectal and gastrointestinal anastomosis after resection of the anorectum and gastrointestinal tract. Some will fall off automatically after healing, and most of them stay in the body. Although the titanium nail material has good compatibility with the human body and can be implanted into the human body in line with national requirements, it remains in the human body as a foreign body for a long time. In the existing literature, there is no relevant information that titanium alloy has no effect on the human body. Therefore, it is better to have foreign bodies in the human body than to have no foreign bodies. Is it possible to design a novel surgical anastomosis that...

Problems solved by technology

[0002] At present, titanium nails and stainless steel nails are used in surgical operations for anorectal and gastrointestinal anastomosis after resection of the anorectum and gastrointestinal tract. Some will fall off automatically after healing, and most of them stay in the body. Although the titanium nail material has good compatibility with the human body and can be implanted into the human body in line with national requirements, it remains in the human body as a foreign body for a long time. In the existing literature, there is no relevant information that titanium alloy has no effect on the human body. Therefore, it is better to have foreign bodies in the human body than to have no foreign bodies. Is it possible to design a novel surgical anastomosis that does not leave any traces after healing? The anastomotic effect of the foreign body stapler can fully meet the clinical requirements. This problem needs to be solved urgently. In addition, when the stapler is placed into the intestinal tract, placing it vertically and horizontally into the intestinal tract will cause the intestinal tract to expand. Increased resistance

It is difficult to put in. When taking it out, because the inner hole of the intestinal tube becomes smaller after the anastomosis, the intestinal hole expands and deforms when it is forcibly taken out, which will cause the sutured nail to be strained and cause bleeding.
