On the other hand, in the present specification and claims, 'suture' refers to various threads such as sutures, threads for embedding, threads for other procedures, surgery, or plastic surgery, or cables or wires, whether or not the outer surface of barbs is processed or disconnected. , plying, or twisting means a comprehensive designation regardless of whether or not.

First, as shown in the perspective view of FIG. 1, the plan view of FIG. 2, and the front view of FIG. 3, the precision needle insertion device (A) for suturing according to the present invention is largely

A needle feeder 10 having a jig 11 for needles N,

A suture transfer 20 having a mover 21 for the suture W;

A relay (31) having a guide hole (H) so that the suture (W) moved by the mover (21) in the transfer is inserted into the hole of the needle tip (Nt) fixed to the jig (11); A guider 30 having a driver 33 moving so that the relay is coupled to the needle tip Nt;

It is configured to include an outlet 60 for discharging the needle N into which the suture W is inserted.

In addition, a plurality of jigs 11 of the feeder 10 are arranged at regular intervals on the turntable A1 so that the work for each process is continuously performed while the turntable rotates,

The base frame where the turntable and the like are located on the upper side has a power unit and a control unit (unspecified) on the lower side,

In addition, it is desirable to have a display capable of monitoring input and work conditions (especially touch screen type), and the four outer posts extend downward, and caster-type wheels and fixing means that ensure ease of movement are connected to the post. It is preferable to be provided on the skeleton (not shown above).

1, a cushion type fixer such as a sponge is inserted into the needle tip (Nt) of the needle (N) into which the suture (W) is injected, as shown in the photograph in the lower right dotted line ellipse of FIG. A fitter 40 is additionally arranged around the turntable A1, in particular, to proceed in the process after the guider 30,

In the post-fixer process, the cap (Nc) of the needle (N) is first separated from the feeder (10), placed in the receptor (11B) of the jig (11), and then coupled to the fixer (43). It is preferable to further provide a capper 50 that covers the needle tip Nt of (N) with the cap Nc again for the implementation of a fully automatic device and the implementation of a work level maximizing satellite characteristics (sterilization room work level).

Specifically, the feeder 10 is a jig 11 of the turntable A in a state in which a plurality of needles N are loaded in a tray or cartridge and loaded on the entry table 10t (see FIG. 2) of the insertion device A. ) Includes a picker (picker) 13 for mounting the needles (N) one by one,

This picker 13 clamps and moves individual needles N from the tray on the table 10t in the form of tongs, as shown enlarged in the upper left dotted line ellipse in FIG. It moves up and down (indicated in the X-axis direction) and left and right (indicated in the Y-axis direction) along the provided transfer rail 15 (refer to the upper part of FIG. 1), and in the forward and backward direction (indicated in the Z-axis direction, FIG. 2 Reference) The movement is solved through the transfer of the table 10t, and if necessary, the X-Y-Z axis movement can be freely transformed and implemented with one picker, such as using equipment such as a robot arm type.

When the individual needles N transferred to the jig 11 by the picker 13 in the tray (not shown) of the table 10t of the feeder 10 are placed on the clamp 11A of the jig 11, the needles N ) of the connector (NC) is engaged by the clamp, and when the picker 13 rises, the cap (Nc) is separated, and the picker transfers the separated cap to a receptor (11B) provided at an adjacent position in the area of the jig. By transferring and inserting, the initial feeding process is completed, and the picker of the feeder is transferred to the initial position for the next transfer.

Subsequently, in FIGS. 1 to 4 , the turntable (A1) rotates to move the needle (N) located on the jig (11) to the position of the transfer (20) and guider (30).

The transfer 20 for supplying the suture W can be configured in various ways according to the type and length of the suture. It is composed of a type in which the suture (W) wound around is continuously supplied.

The transfer 20 includes a reel 23 and a mover 21 that accurately supplies the thin and inflexible suture W without damage,

In this mover 21, the wheels 21A, in particular, a pair of wheels 21A having damage-preventing cushions 21a on the outer circumferential surface are moved by a motor 21B (see FIG. 4), and the intervening suture W is pushed according to the control signal.

In the drawings, a precision needle inserting device for suture is configured in the form of a structure and arrangement for supplying sutures downward in accordance with the direction of gravity, but the feeding direction of the suture may be variously modified as needed.

The suture (W) supplied from the mover (21) of the transfer (20) is supplied to the guider (30) constituting the core of the present invention and is stably and accurately inserted into the hole of the needle tip (Nt) of the needle (N) without error. .

The guider 30 includes a relay 31 having a guide hole H through which a suture W passes, and a clamp 11A of the jig 11 transferred to a position directly below the guider on the turntable A1. ) position (elevating the relay 31 according to the suture being conveyed downward) 33 (see FIG. 3).

When the relay is lowered by this driver, the needle tip (Nt) passes through the guide hole (H) of the relay (31) without colliding (damage can be prevented) with the needle tip (Nt) of the needle (N), especially the oblique tip (Ne). It is essential that it be inserted into

If necessary, the device can be configured in such a way that the needle is inserted into or separated from the guide hole by moving the needle, and the mover 21 is inserted into the needle N as shown in FIG. Left and right to move in the horizontal direction and accommodate the needle in a clamping method (referred to as a representative of the horizontal direction, and specifically defined as a term encompassing the front-back direction or other various angle directions in relation to parts) Part (P1) ,P2) what you can do,

Some or all of these three methods (guider relay lift, needle lift, horizontal movement of relay parts P1 and P2) may be employed.

In addition, the position and structure of the cutter 35 (refer to the schematic diagram in the dotted-dotted ellipse on the left side of FIG. 4) that cuts the suture thread after the needle N of the suture W is inserted is such that the suture passes through the top of the relay 31 in the subsequent needle insertion process. It can be modified in various ways so that it can be accurately inserted into the guide hole through the guide hole.

Furthermore, the relay 31 of the guider 30 is divided up and down to ensure that the suture is fully automatically inserted into the needle accurately despite the difference between the outer diameter and inner diameter of the needle and the outer diameter of the suture, and above all, the oblique tip of the needle tip. A preferred option is

As schematically shown in the front view of FIG. 5 [A], the left plan view in the upper dotted line circle, and the right sectional view,

The relay 31 includes a first body 31A having a small guide hole h1 having a small inner diameter corresponding to the outer diameter of the suture W,

A large guide hole (h2) arranged adjacent to the first powder body, having a large inner diameter corresponding to the outer diameter of the needle tip (Nt), and centered with the small guide hole (h1) It is preferable to have the formed second powder body 31B.

In the figure, it also has left and right relay parts P1 and P2 and is in the form of upper and lower first and second body parts 31A and 31B, so that a total of four blocks constitute the relay 31,

It can be selected as necessary whether it consists of two blocks of only the upper and lower body, or consists of four blocks including the upper and lower body and the left and right parts (P1, P2).

The core concept of the upper and lower first and second powder bodies 31A and 31B is for a suture W (eg, outer diameter 0.09 to 0.12 mm) and a needle N (eg, outer diameter 0.35 mm, inner diameter 0.18 mm),

This is one of the methods for minimizing the tolerance while solving problems caused by the deviation of the outer diameter of the suture as well as the deviation of the length of the needle tip (Nt) of the needle (N) and the deviation of the oblique tip (Ne).

For such precision machining, for example, the small guide hole (h1) of the first powder body (31A) has an inner diameter of about 0.17 mm, and the large (large) guide hole (h2) of the second powder body (31B) is used by combining (various choices such as bolting, riveting, clamping, etc.) precision-processed upper and lower powders to be about 0.40 mm (center alignment of each guide hole (h1) (h2) is essential).

In addition, in order to accurately insert the suture W into the needle despite the length deviation of the needle N and the oblique tip Ne of the needle tip Nt, in the present invention, the relay 31 of the guider 30 is In particular, it is preferable to configure the first powder body 31A or the second powder body 31B, or both, to have a receiving portion accommodating some or all of the oblique tips Ne of the needle tip Nt.

In the schematic cross-sectional view of FIG. 5 [B], an accommodating portion 31R in the form of a ring-groove recess is formed around the lower contact surface of the first body 31A of the relay 31 with the second body, ) The lower part of the guide hole (h1) has a protruding structure, and a small guide hole (h1) that can accommodate a part of the oblique tip (Ne) of the needle tip (Nt) inserted into the large guide hole (h2) Despite this oblique tip, the end of the suture W, which is arranged close to the hole (hole) of the needle N and descends by the mover 21 of the transfer 20, is connected to the oblique tip Ne and the small guide hole. (h1) It is a form in which the small guide hole and the needle hole are configured to be adjacent to each other as much as possible so as not to protrude into the free space between them.

In contrast, FIG. 5 [C] shows a further deformed first powder body 31A, which consists of a first powder body 31A inserted into the upper guide hole hole of the second powder body 31B. The circumference of the end of the first body 31A is processed in a gradually decreasing shape, so that the inclined portion of the first body 31A is in a state where the upper head of the first body 31A is caught around the hole of the second body 31B and is stopped. An accommodating portion 31r is formed between the insertion hole for the first powder or the guide hole of the second powder,

A modified example of a structure in which the oblique tip Ne of the needle tip Nt is accommodated in the accommodating portion 31r and the inclined portion of the first powder body 31A is arranged as closely as possible to the oblique tip or abuts without damaging the tip is proposed.

Furthermore, in FIG. 5 [D], the first powder body 31A is inserted into the guide hole of the relay 31 to form a free body 31M that moves according to an external force, and the free body is provided with a receiving part. The receiving part is a diagonal part (31m) corresponding to the diagonal tip (Ne) of the needle tip (Nt),

After the oblique tip (Ne) of the needle tip (Nt) is inserted into the large guide hole in a form that is not damaged, when it comes into contact with the oblique portion (31m) of the free body (31M), the free body (31M) rotates and the diagonal tip (Ne) ), the oblique part (31m) corresponding to is engaged to take a tight-fitting structure,

Accordingly, the end of the suture (W) descending by the mover 21 of the transfer 20 passes through the small guide hole of the free body 31M and is directly inserted into the hole of the needle without colliding with the oblique tip Ne of the needle. can

The degree of insertion of the lower small-diameter part of the free body 31M is limited by the upper large-diameter part hanging over the upper circumference of the large guide hole of the second body 31B, and the size and weight of the large-diameter part is so that there is no problem of damage to the needle and diagonal tip. It is preferable to be selected so that the oblique portion (31m) of the free body can be rotated and engaged while contacting the oblique tip (Ne) of the needle tip.

On the other hand, Figure 6 shows a locking unit that allows the first and second powders constituting the guider to be separated from each other and then coupled again for maintenance or replacement of the guider.

The locking unit (K) is provided in a first locking member (K10), a second locking member (K20) seated on the first locking member (K10), and the first locking member (K10) to lock the first locking member (K10). It consists of a locking member (K30) for coupling the member (K10) and the second locking member (K20) to each other.

First, the first locking member is provided at one end of the first segment 31A or the second segment 31B of the guider shown in FIG. 5 [A], and the second locking member corresponds to the second segment or the second segment 31B. As provided at one end of one body,

In general, the second powder body and the first powder body have a structure in which the second powder body covers the first powder body in a rectangular frame shape, and the locking unit is provided on one side of the guider so that they can be coupled to each other.

Again, when each configuration is described in more detail, the direction is specified with reference to FIG. 6,

The first locking member (K10) is formed with a coupling fixing portion (K11) to which the second locking member (K20) can be seated and coupled.

The coupling fixing part (K11) may be made of a kind of stepped shape consisting of a side surface and a bottom surface.

In addition, a press hole (K111) is formed on the bottom surface of the coupling fixing part (K11).

The pressing member K12 provided in the first locking member K10 partially protrudes through the pressing hole K111.

In more detail, the pressing member K12 includes a pressing projection K121 partially exposed through the pressing hole K111 and a lower end of the pressing projection K121 interpolated It is made of a pressing casing (K122) configured to allow the pressing protrusion (K121) to go up and down.

In addition, a first elastic body K123 is further provided inside the pressing casing K122 to be in close contact with the bottom surface of the pressing projection K121 so that the pressing projection K121 can receive elastic force in an upward direction.

Therefore, when the pressing protrusion K21 of the second locking member K20, which will be described later, presses the pressing protrusion K121, the pressing protrusion K121 descends and enters the first locking member K10 to be pressed. The casing (K122) is configured to slide inside the first locking member (K10).

Again, it is obvious that a separate passage is formed inside the first locking member K10 in order for the pressing casing K122 to slide, and the first magnet K13 and the second magnet K124 to be described later ), the pressing casing (K122) slides in the first locking member (K10) through the force of attraction.

More specifically, the inside of the first locking member (K10), more precisely, the inside of the bottom surface of the first locking member (K10) connecting a virtual extension line downward along the side surface of the coupling fixing part (K11) A first magnet (K13) is provided, and a second magnet (K124) is provided on one side of the pressed casing (K122), that is, in the direction of the first magnet (K13).

In addition, the first magnet (K13) and the second magnet (K124) are configured to act on each other.

Therefore, in normal times, as the pressing protrusion K121 is partially exposed through the pressing hole K111, the pressing casing K122 does not slide and has no meaning of manpower, but the pressing protrusion of the second locking member K20 When (K21) presses the pressing protrusion (K121), the pressing casing (K122) can slide and move, and at this time, the first magnet (K13) attracts the second magnet (K124) to ) is moved in the direction of the first magnet K13.

When the pressing casing (K122) moves in the direction of the first magnet (K13) in this way, the push protrusion (K122a) formed at the bottom of the pressing casing (K122) operates the locking member (K30), and the locking member (K30) The locking bar K33 of ) is inserted into the locking groove K23 of the second locking member K20 to fix the second locking member K20.

More specifically, first, a separate space is formed at the lower end of the first magnet K13 and the second magnet K124, and the push protrusion K122a is positioned in this space.

That is, the push protrusion K122a has a shape protruding from the lower end of the pressing casing K122 in one direction, that is, in the direction of the locking member K30. Also, in this case, it is preferable that the length of the push protrusion K122a is adjusted so that the end portion does not go over the first magnet K13.

When the pressing casing (K122) slides in the direction of the first magnet (K13) by the above operation, the pressing protrusion (K121) naturally slides beyond the imaginary boundary of the first magnet (K13), At this time, it has a structure that operates by pressing the locking member (K30).

Prior to describing the locking member (K30), first, if the second locking member (K20) is described,

The second locking member (K20) has a locking groove (K23) formed on one side and a pressing protrusion (K21) is provided at the bottom, so when seated on the coupling fixing part (K11), the pressing protrusion (K21) is naturally pressed. It has a structure that is inserted into the hole K111 and presses the pressing protrusion K121 partially exposed through the pressing hole K111,

When combined in this way, the locking groove (K23) has a structure in which the locking bar (K33) of the locking member (K30) to be described later is interpolated.

Again, referring to the locking member (K30), the locking member (K30) is provided inside the first locking member (K10), more specifically, inside the side of the coupling fixing part (K11),

As shown in the drawing, a connecting bar (K32) rotatably provided with respect to a rotating shaft (K35) and a first hinge shaft (K34) at the bottom of the connecting bar (K32)?? It is composed of a push bar (K31) provided to enable hinge movement, and a locking bar (K33) provided to enable hinge movement through a second hinge shaft (K36) at the upper end of the connecting bar (K32).

Therefore, the push bar (K31) and the locking bar (K33) have a structure that can slide in opposite directions by the rotational movement of the connecting bar (K32) with respect to the rotation shaft (K35).

As a result, when the pressing casing (K122) moves in the direction of the first magnet (K13), the push protrusion (K122a) pushes the push bar (K31), and accordingly, the locking bar (K33) is the coupling fixing part By protruding from the side of (K11) and being inserted into the locking groove (K23) of the second locking member (K20), they have a structure capable of fixing them to each other.

Furthermore, as a safety device for fixing the locking bar K33 more firmly, a partition wall part K22 is formed in the locking groove K23 of the second locking member K20, opposite the partition wall part K22. A second pulling member K24 is provided, and a fourth magnet K243 is provided at an end of the second pulling member K24.

In addition, a third magnet K331 having an attractive force with the fourth magnet K243 is further provided at an end of the locking bar K33.

Therefore, when the locking bar K33 is inserted into the locking groove K23, the third magnet K331 at the end of the locking bar K33 and the fourth magnet K243 of the second pulling member K24 are connected to each other. It is possible to prevent the locking bar (K33) from being arbitrarily removed from the locking groove (K23) by trying not to fall by manpower.

Here, it is preferable that the barrier rib portion K22 is configured thinly so that manpower can pass through. 4 This is to prevent the magnet (K243) from being attached.

As described above, since the first locking member K10 and the second locking member K20 are firmly fixed to each other, an operation of separating them from each other will be described.

First, in order to separate them from each other, the safety device provided in the second locking member K20 described above must be released (an operation of separating the third magnet K331 and the fourth magnet K243 far from each other).

To this end, as briefly described above, a second pulling member K24 is further provided in the second locking member K20.

The second pulling member K24 includes a second pulling string K241, a second pulling ring K242 provided in the second pulling string K241, and a fourth magnet K243.

More specifically, the second pull string K241 is located on the opposite side of the locking groove K23 based on the partition wall part K22, and at both ends thereof, a fourth magnet K243 and a second pull ring K242 ) is provided.

At this time, the second pull ring (K242) has a structure that protrudes to the outside of the second locking member (K20).

Therefore, in order to release the safety device, the user pulls the second pull ring K242, and through this operation, the fourth magnet K243 naturally moves away from the third magnet K331 so that no attraction is applied to each other.

Again, in order to separate the second locking member (K20) from the first locking member (K10), the locking bar (K33) must be separated from the locking groove (K23),

This is ultimately solved by returning the pressed casing (K122) to its original position, and for this purpose, the first locking member (K10) of the present invention further includes a first pulling member (K15).

Similar to the second pulling member K24, the first pulling member K15 has one end fixed to the pressing casing K122 and the other end having a first pulling ring K152. A first pulling strap K151 It consists of

In addition, the first pull ring (K152) is configured to be exposed to the outside of the first locking member (K10).

Therefore, when the user pulls the first pull ring (K152), the first magnet (K13) and the second magnet (K124) are gradually separated, and when the pressing protrusion (K121) is located in the pressing hole (K111), the first 1 The pressing protrusion (K121) rises by the elastic force of the elastic body (K123) and returns to its original position to be partially exposed in the pressing hole (K111) while pushing the pressing protrusion (K21) located in the pressing hole (K111). Although the second locking member K20 cannot be raised only by the elastic force of the elastic body K123, this is one of the separation processes, and the second locking member K20 is moved to the first locking member while pulling the first pulling member K15. (K10) can be solved by an external force.)

In addition, a second elastic body (K37) is provided on one side of the push bar (K31) (in the opposite direction to the push protrusion (K122a)) to push the push bar (K31) in the direction of the push protrusion (K122a), so that it is naturally locked. The bar (K33) has a structure that can be returned to its original position (it comes out of the locking groove (K23) and is located inside the first locking member (K10) again).

Next, after the suture (W) is inserted into the hole of the needle (N) by the transfer 20 and the guider 30, a suture (W) of a predetermined length is placed on the top of the needle as shown in the dotted line ellipse of FIG. is cut by the cutter 35 in an exposed form,

The relay 31 is separated from the needle N, and the suture insertion needle is transferred to the position of the fitter 40 by the rotation of the turntable A1.

The fixer 40 allows a cushion-type fixer 43 such as a sponge to be inserted into the needle tip Nt of the needle N into which the suture W is injected in a manner that encloses the suture thread. ,

The fixer 43 is supplied from a press-punched soft panel (a panel made of materials such as paper, synthetic resin, rubber, and silicone), and the soft panel 43A is transferred left and right as shown in FIGS. 1 and 2 placed on the table,

If necessary, the work table may be configured such that the soft panel 43A is arranged on a jig having protrusions formed at positions corresponding to the plurality of fixers 43 so that the fixer 43 protrudes from the soft panel to a predetermined height.

The fitter 41 is composed of a tongs type, etc. (refer to the circle in the lower right dotted line in FIG. 2), clamps the fixer 43 and inserts it into the oblique tip Ne of the needle N, and is drilled at the lower right one point in FIG. It should be inserted in the same form as the picture in the dashed line ellipse.

After stabilizing the needle (N) inserted suture (W) by the fixer (43) in the fixer (40), the needle is transferred to the position of the capper (50) by the rotation of the turntable (A1), and this With the operation of the capper 50, especially the tong-type capper 50 capable of lifting and moving left and right (refer to the lower right dotted line circle in FIG. 3)

The cap (Nc) located on the receptor (11B) of the jig (11) is clamped, and the needle tip (Nt) of the needle (N) is covered with the cap (Nc) again.

Finally, the needle N into which the suture W is inserted, especially the needle coupled back to the cap Nc, is discharged from the outlet, and the outlet 60 is configured so that the capper 50 functions in the drawing (if necessary). Various outlet configurations are possible),

At the same time as the clamp 11A of the jig 11 is released, the capper 50 is transported as it is in the state of clamping the needle, and after unclamping, it is transferred to the discharge conveyor, or the first soft powder (bag, etc.) or hard material for individual or unit packaging It can be configured in a way that unclamping after inputting up to 1 body (hard synthetic resin box, etc.).

Furthermore, if necessary, a vision camera and a defective product collection unit may be additionally configured to determine whether the needle is good or bad and to separate and discharge the outlet or the needle into which the suture was previously inserted.
