Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with various embodiments shown in the drawings. However, these implementations do not limit the present invention, and any structural, method, algorithmic or functional transformations made by those skilled in the art based on these implementations are included in the protection scope of the present invention.

[0028] The words expressing position and direction described in the present invention are all based on the operator (not shown) of the round tube stapler 100 of the present invention as a reference, the end close to the operator is the proximal end, and the end far away from the operator is remote.

[0029] Please refer to Figure 1 to Figure 10 Shown is a preferred embodiment of the round tube stapler 100 of the present invention. The circular tubular stapler 100 includes a stapler body 1, an anvil assembly 2 arranged outside one end of the stapler body 1, a knob 3 fixed at the other end o...

Abstract

The invention provides a circular tube-type anastomat. The circular tube-type anastomat comprises a shell, a nail anvil pull rod, a nail push rod, a knob and a percussion handle, wherein the nail anvil pull rod is accommodated in the shell; the nail push rod is sheathed onto the nail anvil pull rod; the knob is connected with the near end of the shell so as to control the nail anvil pull rod to move; and the percussion handle is pivotally connected onto the shell and is abutted with the near end of the nail push rod. The circular tube-type anastomat also comprises a safety mechanism movably positioned in the shell so as to limit the movement of the percussion handle. The safety mechanism comprises a locking piece, a safety block and a torsional spring, wherein the locking piece can be abutted with or separated from the percussion handle; the safety block is relatively arranged on the near end of the locking piece; and the torsional spring is connected with the locking piece and the safety block. The nail anvil pull rod is provided with a stay rod pin, and the safety block is provided with a shifting chute matched with the stay rod pin. When the knob is rotated to a percussion position, the locking piece is separated from the percussion handle. According to the circular tube-type anastomat provided by the invention, mistake percussion can be effectively prevented from occurring, so that surgical procedures are simpler and more convenient.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a round tube stapler. Background technique [0002] Surgeons usually use special anastomosis when they need to connect the remaining good tubular physiological tissues after surgical resection of cancerous parts of human tubular physiological tissues such as the intestinal tract and esophagus, or when performing hemorrhoid cutting and anastomosis. The nails are sutured with a circular stapler. [0003] Existing round-tube staplers generally include a stapler body, a firing handle pivotally connected to the stapler body, and an anvil block assembly matched with the stapler body. The stapler body includes an annular staple cartridge located at the distal end, an annular cutter, staples disposed in the staple cartridge, an anvil pull rod connected to the nail seat assembly, and an anvil rod arranged between the staple cartridge and the firing handle to fire the circular...
