Nail abutting seat structure of disposable endoscope cutting anastomat

Abstract

The invention discloses a nail abutting seat structure of adisposable endoscopic cutting anastomat. The nail abutting seat structurecomprises a connector, a shaft column, an electric telescopic rod, a shaft rod, a motor, a pushing piece and a nail seat, the pushing piece is slidably connected to the inner bottom of a first clamp, a cutting knife is fixed to the middle of the upper end face of the pushing piece, compression springs are symmetrically fixed to the two sides of the nail seat, the outer sides of the compression springs are connected with sliding blocks, and a suturing nail is clamped on the nail base and penetrates through the upper end face of the first clamp. According to the nail abutting seat structure of the disposable endoscope cutting anastomat, after the first clamp and a second clamp are closed together to clamp tissue, the cutting knife can slide rightwards along with the pushing piece, the tissue can be cut open conveniently, at the moment, the nail seat can move upwards under the pushing effect of the pushing piece, a suturing nail is continuously knocked out, the suturing nail is bent and embedded into the tissue under the abutting and supporting effect of the abutting block, suturing operation is conveniently completed, the whole operation is completed electrically, and the automation degree is high.

Description

technical field [0001] The invention relates to the related technical field of endoscopic cutting staplers, in particular to a nail seat structure of a disposable endoscopic cutting stapler. Background technique [0002] Laparoscopic stapler (endoscopic cutting stapler and disposable nail box) is one of the important instruments in laparoscopic surgery. It replaces traditional manual suture and uses titanium nails to separate or anastomose tissues. It is easy and fast to operate and greatly The operation time is shortened. The laparoscopic stapler makes the operation field narrow, and the manual anastomosis of deep parts becomes easy, accurate, firm and reliable, and significantly reduces the incidence of anastomotic leakage. In laparoscopic surgery, one-time The laparoscopic cutting stapler can be used for the separation, resection and suturing of tissues. It can effectively suture the tissue and provide a good hemostasis effect. It is inconvenient for some anvils to posit...

Problems solved by technology

[0003] The purpose of the present invention is to provide a disposable laparoscopic cutting stapler anvil structure to solve the problem that the existing anvil proposed in the background technology is inconvenient to position the clamp before firing the staples, and the clamp is difficult to Precise alignment of tissue without a high degree of automation
