When the device is used, the positioning groove structure is arranged on the inner wall of the fixture block 93, the positioning block structure is arranged on the outer side of the nail seat 931 and is matched with the positioning groove structure, the positioning tube 92, the fixture block 93, the push rod 94, the axes of the nail seat assembly 95 and the conical head 96 are the same straight line, the circle center of the positioning hole 951 is located on the central axis of the nail seat assembly 95 and is matched with the size of the push rod 94 in size, the top of the push rod 94 is inserted into the positioning hole 951, and the splicing installation of the device can be completed at the moment.
The above structure and process are shown in FIGS. 1-10.
Assuming that there are nine staple positions for suturing, after the tissue is cut and sutured, there are nine groups of staple holes 932, the distances and angles between two adjacent groups of staple holes 932 are the same, there are nine groups of shaping holes 952, and the nine groups of shaping holes 952 correspond to the nine groups of staple holes 932, so that the sutured state is as shown in fig. 11, that is, the nine staple positions are uniformly distributed.
The movable contact 12 is long, the distance between the fixed contact 13 and the midpoint of the rotating rod 11 is smaller than the size of the movable contact 12, and the length of the movable contact 12 is smaller than the distance between the rotating rod 11 and the nail position.
Please refer to fig. 11 for the above structure and process.
In the initial state, the fixture block 93 and the nail abutting seat assembly 95 are separated from each other, and when the tissue needs to be cut, the two are in a mutual contact state, at this time, the suturing nail inside the nail seat 931 extends out of the nail hole 932, passes through the tissue to be sutured and then contacts with the shaping hole 952, at this time, the suturing nail starts to bend under the pressure of the nail seat 931 and finally forms a 'B' shape.
After the sewing is completed, the fixture block 93 and the nail seat 931 are rotated and moved downwards, because nine rotating rods 11 and pull wires 10 are provided, nine rotating rods 11 are uniformly distributed by taking the circle center of the nail abutting seat assembly 95 as a reference, that is, the distance and the angle between two adjacent rotating rods 11 are the same, nine rotating rods 11 respectively correspond to nine pull wires 10, one ends of the nine pull wires 10 far away from the rotating rods 11 are respectively movably connected with nine auxiliary sliders 152, the heights of the nine self-locking mechanisms 15 in the horizontal direction in the initial state are the same and are all located at the bottom of the limiting groove 14, the rotating rods 11 and the movable contacts 12 can rotate under the action of the pull wires 10, the movable contacts 12 are the same, the distance between the fixed contacts 13 and the middle points of the rotating rods 11 is smaller than the size of the movable contacts 12, and the length of the movable contacts 12 is smaller than the distance between the rotating rods 11 and the nail positions, so that nine long strip nail positions are completely and fully sewn, the movable contact 12 will contact with the suturing nail, and the suturing nail will block its position after contacting with the movable contact 12, so that it cannot rotate continuously, i.e. cannot contact with the fixed contact 13, and at this time, the circuit of the indicator light externally connected with the fixed contact 13 is in the off state, i.e. the suturing is completed and the nail level is correct.
The above structure and process are shown in FIGS. 11-13.
Because the inside of spacing groove 14 is provided with the tooth, movable rod 153 is total two, for articulated state and pin joint position in the front of vice slider 152 between two movable rods 153, swing joint has reset spring between two movable rods 153, the one end that two movable rods 153 kept away from vice slider 152 is provided with dentate structure, this dentate structure and the inside tooth looks adaptation of spacing groove 14, under the initial condition, two movable rods 153 are great in angle degree under reset spring's effect, the dentate structure of movable rod 153 and the inside tooth meshing of spacing groove 14, main slider 151 and vice slider 152 are fixed relatively in the inside position of spacing groove 14 this moment, can drive spacing groove 14 and its inside main slider 151 and vice slider 152 synchronous motion when push rod 94 moves.
Since the rotating rod 11 is movably connected with the sub-slider 152 through the pull wire 10, when the movable contact 12 rotates to contact with the staples, since the staples limit the position of the movable contact 12, the pull wire 10 starts to apply an upward pulling force to the sub-slider 152 at this time, the angle between the two movable rods 153 is reduced at this time, and the main slider 151 can move inside the limit groove 14, that is, the movement of other structures is not affected at this time.
The above structure and process are shown in FIGS. 14-19.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
