Example (b):

as shown in fig. 1 and 2, the labor-saving anorectal anastomat comprises a shell 1. A push rod 2 is connected in the shell 1 in a sliding way. A handle 3 is hinged on the side wall of the shell 1, and the handle 3 drives the push rod 2 to move along the length direction of the handle through a conduction mechanism 5. A reset elastic piece 4 is fixed in the shell 1, and the reset elastic piece 4 is connected with one end of the push rod 2 close to the handle 3. The return elastic member 4 is a spring. A nail box assembly (not shown in the figure) is connected to one end of the push rod 2 far away from the handle 3.

The conduction mechanism 5 comprises a connection plate 51, a first wheel 52 and a second wheel 53. The first rotating wheel 52 and the second rotating wheel 53 are rotatably connected to the outer wall of the push rod 2, and a gap is formed between the first rotating wheel 52 and the second rotating wheel 53. One end of the connecting plate 51 is fixed on the handle 3, and the other end is inserted into the gap. The first runner 52 and the second runner 53 are arranged in parallel.

Pressing handle 3, through lever principle, making connecting plate 51 contradict with first runner 52 and promote push rod 2 and remove, reset elastic component 4 deformation and produce elasticity, loosen handle 3 after, make push rod 2 reset through the elastic force effect, simultaneously, first runner 52 contradicts with connecting plate 51 and makes handle 3 reset. The handle 3 cannot rotate reversely through the limiting function of the second rotating wheel 53. In the process that the connecting plate 51 drives the push rod 2 to move through the first rotating wheel 52, the friction force is small, and therefore the doctor can press the handle 3 more easily.

A connecting rod 6 penetrating the push rod 2 is slidably connected in the shell 1, and the connecting rod 6 can extend out of the shell 1 after penetrating the push rod 2. One end of the connecting rod 6 close to the nail bin assembly is provided with a nail abutting seat assembly 61, and the other end is in threaded connection with an adjusting button 7. The adjusting knob 7 is rotatably connected to the housing 1.

A first magnet 81 is fixed to the end of the handle 3 remote from the hinge and the first magnet 81 is located on the side of the handle 3 facing the housing 1. An elastic positioning ring 90 is rotatably connected to the outer wall of the housing 1 near one end of the adjustment knob 7, and a second magnet 82 attracted to the first magnet 81 is fixed to the positioning ring 90. A limiting mechanism 9 is arranged between the positioning ring 90 and the shell 1.

The limiting mechanism 9 includes a limiting groove 91, an elastic sheet 92, a limiting hole 93 and an annular caulking groove 94. An annular groove 94 opens on the outer wall of the housing 1, and the retaining ring 90 is rotatably connected to the annular groove 94. The limiting groove 91 is formed in the inner wall of the annular caulking groove 94, the elastic sheet 92 is bent into a V shape, and two ends of the elastic sheet are fixed in the limiting groove 91, so that the middle of the elastic sheet 92 is provided with a protrusion. The limiting hole 93 is opened on the side wall of the positioning ring 90, and the protrusion is embedded in the limiting hole 93. Two limit holes 93 are formed, and the two limit holes 93 are uniformly distributed along the axis of the positioning ring 90. The limit hole 93 is opened on the side wall of the positioning ring 90.

The holding ring 90 is rotated to overcome the friction between the protrusion and the holding hole 93, and when the second magnet 82 faces the first magnet 81, the other holding hole 93 corresponds to the protrusion, and the protrusion is inserted into the holding hole 93. Positioning of the positioning ring 90 is achieved. Pressing handle 3, first magnet 81 is close to toward the direction of second magnet 82, through the magnetic attraction effect, makes first magnet 81 contradict with second magnet 82, and at this moment, handle 3 location does not need the doctor to continuously press handle 3 promptly, reaches laborsaving purpose.

In order to facilitate the rotation of the positioning ring 90 to facilitate the movement of the second magnet 82, an anti-slip groove 900 is formed on the outer wall of the positioning ring 90, and a plurality of anti-slip grooves 900 are uniformly distributed along the axial center of the positioning ring 90.

In order to facilitate the rotation of the knob 7, a grip groove 71 is formed on an outer wall of the knob 7.

In summary, when in use, the adjusting knob 7 is rotated forward, and the connecting rod 6 is moved away from the adjusting knob 7 by thread conduction. The nail holder assembly 61 is placed on the affected part, and the affected part is placed between the nail holder assembly 61 and the nail bin assembly. Then the adjusting button 7 is rotated reversely, so that the nail abutting seat assembly 61 and the nail bin assembly clamp the affected part. The positioning ring 90 is rotated 180 degrees to make the second magnet 82 face the first magnet 81, then the handle 3 is pressed, and the push rod 2 drives the nail bin seat assembly to move towards the direction close to the nail abutting seat assembly 61, so that the titanium nail is sewn on the affected part. At this time, the first magnet 81 and the second magnet 82 are bonded by the magnetic attraction. The process of continuously pressing the handle 3 is avoided. After the handle 3 is held for 30 seconds, the positioning ring 90 is rotated again by 180 degrees, separating the first magnet 81 from the second magnet 82. The push rod 2 is reset through the elastic action of the reset elastic piece 4, the adjusting button 7 is rotated in the forward direction, the nail supporting seat assembly 61 is separated from the affected part, and finally the nail supporting seat assembly is drawn out from the affected part, so that the operation is simple and convenient.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
