  2 to 4 are front views according to various usage states of the suture instrument for laparoscopic surgery according to the first embodiment of the present invention. Referring to FIGS. 2 to 4, the first jaw 210, the second jaw 220, the hinge shaft 223, the shaft 230, the grip 240, the first rod 250, the locking claw 255, A second rod 260, a stopper 270, and a spring 275 are shown.

  In the present embodiment, the first jaw 210 and the second jaw 220 which are interlocked to clamp the suture site are directed in the length direction in which the shaft 230 extends, or correspond to the operation of the user. Thus, it rotates in a direction different from that direction. That is, when the jaw including the first jaw 210 and the second jaw 220 is inserted into the abdominal cavity, the jaw 230 faces in the length direction in which the shaft 230 extends. It can be rotated in a direction that forms an angle, for example, in a vertical direction. Further, when the instrument according to the present embodiment is inserted or withdrawn into the abdominal cavity through the surgical trocar, the jaw faces the length direction in which the shaft 230 extends by the inner wall of the surgical trocar, and is inserted into the abdominal cavity. A feature is that a predetermined angle can be formed with the shaft 230 by a predetermined rotational force.

  The diameter of the jaw in which the first jaw 210 and the second jaw 220 mesh with each other may be smaller than the diameter of the shaft 230. In this case, if the shaft 230 can be inserted into the abdominal cavity, the chin can also be inserted. Therefore, there is an advantage that the entire instrument can be inserted without the need to further widen the wound. Further, in this case, since the jaw can be accommodated in the shaft 230, there is an advantage that insertion and storage are convenient.

  Since the first jaw 210 and the second jaw 220 can be engaged with each other by forming saw blades that intersect each other, a suture site is interposed between the first jaw 210 and / or the second jaw 220. Can be sewn with a needle inserted into a channel that penetrates both ends of the.

  The distance between the first jaw 210 and the second jaw 220 is adjusted to clamp the suture site. The first rod 250 is coupled to one end of the first jaw 210 adjacent to the hinge shaft 223, and rotates the first jaw 210 about the hinge shaft 223 in the counterclockwise direction when moving. 210 and the second jaw 220 are engaged with each other.

  For this purpose, the first jaw 210 can be coupled directly to the first rod 250 or by a coupling means such as a wire. For example, when the first rod 250 is pulled to the lower part when one end is coupled to the first rod 250 and the other end is coupled to the first jaw 210 while detaching the hinge shaft 223, the wire is A rotational force is transmitted to the first jaw 210. When this rotational force is a rotational force that rotates counterclockwise about the hinge shaft 223, the first jaw 210 rotates counterclockwise and meshes with the second jaw 220. In order to generate such a rotational force, the other end of the wire can be coupled to the first jaw 210 on the left side of the hinge shaft 223 in FIG.

  A portion of the first rod 250 for clamping the suture site between the first jaw 210 and the second jaw 220 may be formed by a spring 253. That is, when a part of the first rod 250 is formed by the spring 253, a buffer is formed by the spring 253 when the thickness of the target suture site changes, so that the suture site can be prevented from being damaged and clamped. There is an advantage that a constant pressure can be maintained. The position where the spring 253 is formed may be an intermediate region of the first rod 250 or an arbitrary region.

  The case where the first jaw 210 and the second jaw 220 are engaged with each other is shown in FIG. Referring to FIG. 3, the first rod 250 is pulled downward, and the locking claw 255 formed on the first rod 250 is fixed by the stopper 270.

  The stopper 270 can stop its movement by generating a rotational force by an elastic member such as the spring 275 and locking the first rod 250 by being locked by the locking claw 255. That is, the elastic member causes one end of the stopper 270 coupled thereto to be separated from the shaft 230, and the other end of the stopper 270 receives a force approaching the first rod 250 by the rotation shaft of the stopper 270. Therefore, the stopper 270 fixes the first rod 250 by the force of the elastic member.

  The inclined form of the stopper 270 and the locking claw 255 can be determined in a form for maintaining the state in which the first jaw 210 and the second jaw 220 clamp the suture site. Referring to FIG. 3, the first jaw 250 is rotated while the first rod 250 is pulled downward. Therefore, in order to maintain this state, the stopper 270 is not moved in the direction in which the first rod 250 does not rise. And the locking claws 255 are inclined.

  Further, when the first rod 250 is raised upward, the jaw is reopened as shown in FIG. 2, so that the first jaw 210 exerts a rotational force clockwise about the hinge shaft 223. Can receive. Various embodiments for this purpose can be applied to the present invention. For example, an elastic member (for example, a spring) is inserted into the hinge shaft 223 so that the first jaw 210 rotates clockwise around the hinge shaft 223. it can be made to rotate in the.

  Accordingly, the user can contract or expand the jaw by linearly moving the first rod 250 in the length direction in which the shaft 230 extends. In this case, a protruding locking claw (not shown) can be formed in the rotational direction of the first jaw 210 to determine the maximum angle that the first jaw 210 forms with the second jaw 220.

  The second rod 260 moves the first jaw 210, the second jaw 220, and the hinge shaft 223 so that the length direction of the first jaw 210 and the second jaw 220 is the length of the shaft 230. The direction can be changed and combined, and these can be accommodated inside the shaft 230. The second rod 260 can be accommodated inside the first rod 250. Further, the second rod 260 can also perform a linear motion to perform the above-described function.

  FIG. 4 shows a case where the first jaw 210, the second jaw 220, and the hinge shaft 223 are accommodated in the shaft 230.

  Referring to FIG. 4, the first jaw 210, the second jaw 220, and the second rod 260 coupled to the hinge shaft 223 are pulled downward, and the first jaw 210, The second jaw 220 and the hinge shaft 223 are accommodated inside the shaft 230. Although the coupling relationship between the second rod 260 and the first jaw 210, the second jaw 220, and the hinge shaft 223 is not shown, they can be directly coupled or coupled by a wire.

  It goes without saying that various other methods for adjusting the distance between the first jaw 210 and the second jaw 220 can be applied to the present invention. For example, according to the above description, the case where the first jaw 210 and the second jaw 220 rotate around the same hinge shaft 223 is described. However, the first jaw 210 and the second jaw 220 rotate around a plurality of different hinge shafts. while it is also possible to mesh with each other.

  Further, according to another embodiment, the case where the first jaw 210 and the second jaw 220 mesh with each other around the hinge shaft 223 has been described. However, the distance between the first jaw 210 and the second jaw 220 is parallel in the length direction. adjusted is also possible. For example, the first jaw 210 is coupled to a hinge shaft provided on the shaft 230, and the second jaw 220 is coupled to a hinge shaft provided at one end of the first rod 250, so that the first rod As the second jaw 220 moves in a state of being parallel to the first jaw 210 by the movement of 250, the second jaw 220 can be engaged with this.

  In the method for using the suture instrument for laparoscopic surgery according to the present embodiment, first, the jaw including the first jaw 210 and the second jaw 220 for clamping the suture site is placed in parallel with the shaft 230 in the patient's abdominal cavity. Insert into the mirror. Inside the laparoscope, the jaw is rotated at a predetermined angle with respect to the shaft 230 so that the jaw clamps the suture site. Thereafter, the suture instrument for laparoscopic surgery according to the present embodiment can be used by passing the needles through the channels 215 and 225 formed in the jaw and suturing the suture site.

  5 is a partial side view of one end of the jaw as viewed from the direction A in FIG. 2, and FIG. 6 is a partial perspective view of the other end of the jaw shown in FIG. The first jaw 210 and the second jaw 220 are formed with channels 215 and 225 penetrating both ends thereof. In the channels 215 and 225, needles (not shown) are inserted, and suture sites are sutured. The first jaw 210 and the second jaw 220 have grooves 217 formed on the surfaces facing each other, so that the sutured portion can be strongly clamped.

  The channels 215 and 225 may have a funnel shape in which the diameters of the inner surfaces of the open surfaces decrease toward the back. Such a funnel-shaped open surface has a large insertion area and can accommodate a slightly bent needle, so that the needle can be easily inserted into the channels 215 and 225 as a result.

  Referring to FIG. 6, a plurality of grooves formed in a direction perpendicular to the grooves 217 are shown on the surface of the first jaw 210 opposite to the second jaw 220. sewn by the needle entered. Due to the multiple grooves, the channels 215 and 225 are cut to form multiple open surfaces, and such multiple open surfaces may also be funnel-shaped. Therefore, the needle inserted from the open surface at one end of the channels 215 and 225 has an effect that it can easily penetrate the channels 215 and 225 until it exits from the open surface at the other end.

  FIG. 7 is a front view of a suture instrument for laparoscopic surgery according to the second embodiment of the present invention. Referring to FIG. 7, the first jaw 710, the second jaw 720, the shaft 730, the grip 740, the first rod 750, the locking claw 755, the second rod 760, and the stopper 770, a spring 775, a Caesar link 780, and a bending portion 785 are shown. Description will be made centering on differences from the above-described embodiment.

  The first jaw 710 and the second jaw 720 are parallel to each other and each end is coupled to a Caesar link 780. The Caesar-type link 780 is a scissor-shaped link that increases in width when shortened in the length direction and decreases in width when lengthened in the length direction. One end of the Caesar type link 780 is coupled to the first rod 750 and is controlled by the first rod 750. That is, the Caesar type link 780 is changed in length and width by the movement of the first rod 750, and the interval between the first jaw 710 and the second jaw 720 is also changed.

  The first rod 750 may be directly connected to the Caesar-type link 780 or may be connected via a wire. In FIG. 7, the coupling relationship through the wire is shown.

  The Caesar type link 780 and the first jaw 710 and the second jaw 720 can be coupled to each other along a groove in a direction perpendicular to the length direction of the shaft 730 at the joint portion. That is, the length of the Caesar type link 780 is changed around the coupling site between the Caesar type link 780 and the first jaw 710 and the second jaw 720, and the distance between the first jaw 710 and the second jaw 720 is changed. So that the first jaw 710 and the second jaw 720 can be connected to each other at the portion where the shaft 730 is connected. Of course, it is needless to say that the present embodiment can be implemented in a coupling form that is not uneven coupling.

  The bending portion 785 is provided at one end of the shaft 730 and accommodates the caesar type link 780 and is bent. That is, since the bending part 785 is bent according to the user's operation, when the user inserts the bending part 785 in the abdominal cavity, the bending part 785 is directed in the same direction as the length direction of the shaft 730 and the jaw is positioned in the abdominal cavity. After the insertion, the bending portion 785 is bent in a direction convenient for suturing and can be sewn conveniently.

  The bending angle of the bending part 785 is controlled by the operation of the second rod 760. For this reason, the bending part 785 and the second rod 760 can be connected to each other by a wire. For example, the bending part 785 has a property of being directed in the same direction as the length direction of the shaft 730 by an elastic force, and the wire can be connected to one side wall inside the bending part 785. In this case, when the second rod 760 is pulled downward, the bending portion 785 bends in one direction due to the tension of the wire. The user can turn the jaw toward the suture site by rotating the entire shaft 730 about the length direction. In addition to this, it goes without saying that various mechanisms that can bend the bending portion 785 using a wire can be applied to this embodiment.

  8 to 10 are front views according to various usage states of the suture instrument for laparoscopic surgery according to the third embodiment of the present invention. 8 to 10, the first jaw 810, the first hinge shaft 815, the second jaw 820, the second hinge shaft 825, the shaft 830, the grip 840, and the main rod 850, a locking claw 855, a stopper 870, a spring 875, and a rotating member 880 are shown. Description will be made centering on differences from the above-described embodiment.

  The first jaw 810 is pivotally coupled to a first hinge shaft 815 provided on the shaft 830, and the second jaw 220 is coupled to a second hinge shaft 825 provided at one end of the main rod 850. . The first jaw 810 and one end of the main rod 850 are coupled by a rotating member 880. The rotating member 880 is a member that applies a rotational force to the first jaw 810, and may be an elastic member having an elastic force such as a spring or a rubber string.

  The first jaw 810 receives a rotational force so as to rotate clockwise about the first hinge shaft 815 by another elastic member provided on the first hinge shaft 815, for example, an elastic spring. Further, the second jaw 820 receives a rotational force so as to rotate counterclockwise about the second hinge shaft 825 by an elastic member provided on the second hinge shaft 825.

  If the distance between the first jaw 810 and the main rod 850 is increased by pulling the main rod 850 downward, both the first jaw 810 and the second jaw 820 are parallel to the length direction of the shaft 830.

  FIG. 13 is a front view of a suture instrument for laparoscopic surgery according to the fourth embodiment of the present invention. Referring to FIG. 13, a first jaw 810, a first hinge shaft 815, a second jaw 820, a second hinge shaft 825, a shaft 830, a grip 840, a main rod 850, A spring 853, a locking claw 855, a stopper 870, a spring 875, a first rotating rod 890, a second rotating rod 895, an elastic member 896, and a lever 893 are shown. The description will focus on the differences from the above.

  In this embodiment, the first jaw 810 is rotated using the first rotating rod 890 without the separate rotating member 880 coupled to the first jaw 810 and the main rod 850, and the second rotating rod 895 is rotated. Is used to rotate the second jaw 820.

  The first rotating rod 890 is coupled to the first jaw 810 so that one end thereof is separated from the first hinge shaft 815 by a predetermined distance, and a lever 893 is provided at the other end. The lever 893 protrudes from the side surface of the shaft 830, and can be identified by being locked by a stopper, a latch, or another insertion groove as described above. The user rotates the first jaw 810 coupled to one end of the first rotating rod 890 by moving the lever 893 in the axial direction of the shaft 830. For example, when one end of the first rotating rod 890 is coupled to the left side of the first hinge shaft 815 shown in FIG. 13, when the first rotating rod 890 moves downward, the first jaw 810 is When the first rotating shaft 815 rotates counterclockwise and the first rotating rod 890 moves upward, the first jaw 810 rotates clockwise about the first hinge shaft 815. .

For example, when one end of the second rotating rod 895 is coupled to the right side of the second hinge shaft 825 shown in FIG. 14, the second rotating rod 895 is moved by the elastic force of the elastic member 896 coupled to the other end. To push the second jaw 820, the second jaw 820 continues to receive a force that rotates counterclockwise about the second hinge shaft 825. Further, when one end of the second rotating rod 895 is coupled to the left side of the second hinge shaft 825 shown in FIG. 14, the second rotating rod 895 is caused by the elastic force of the elastic member 896 coupled to the other end. The second jaw 820 can be pulled, and in this case, the second jaw 820 continues to receive a force that rotates counterclockwise about the second hinge shaft 825.

  Accordingly, when the second jaw 820 coupled with the main rod 850 is released to the outside of the shaft 830, the second jaw 820 is transmitted counterclockwise by receiving the elastic force of the elastic member 896. By rotating, it can be arranged in a direction perpendicular to the extending direction of the shaft 830.

  A part of the first rotating rod 890 and / or the main rod 850 may be formed by a spring 853. The spring 853 is a general spiral spring, and can act to absorb and buffer impact energy. As described above, when a part of the first rotating rod 890 and / or the main rod 850 is formed by the spring 853, the impact is buffered by the spring 853 when the thickness of the target stitching site changes, and the stitching site. Can be prevented, and can maintain a constant pressure for clamping.

  FIG. 14 is a front view of a suture instrument for laparoscopic surgery according to the fifth embodiment of the present invention. Referring to FIG. 14, the first jaw 810, the first hinge shaft 815, the second jaw 820, the second hinge shaft 825, the shaft 830, the grip 840, the main rod 850, A spring 853, a locking claw 855, an insertion groove 857, a fixing means 858, a stopper 870, a spring 875, a first rotating rod 890, a second rotating rod 895, and a lever 893 are shown. It is. The difference from the above will be mainly described.

  Referring to FIG. 14, the first jaw 810 is rotated using the first rotating rod 890 without the separate rotating member 880 coupled to the first jaw 810 and the main rod 850, and the main rod 850 is rotated. The second jaw 820 is rotated using a second rotating rod 895 extending to one end.

  The first rotating rod 890 is coupled to the first jaw 810 so that one end thereof is separated from the first hinge shaft 815 by a predetermined distance, and a lever 893 is provided at the other end. The lever 893 is formed to protrude from the side surface of the shaft 830, and the position of the lever 893 can be specified by being locked by a stopper, a latch, or another insertion groove as described above. The user rotates the first jaw 810 coupled to one end of the first rotating rod 890 by moving the lever 893 in the axial direction of the shaft 830. For example, when one end of the first rotating rod 890 is coupled to the left side of the first hinge shaft 815 shown in FIG. 14, when the first rotating rod 890 moves downward, the first jaw 810 is When the first rotating shaft 815 rotates counterclockwise and the first rotating rod 890 moves upward, the first jaw 810 rotates clockwise about the first hinge shaft 815. .

  In addition, the second rotating rod 895 is coupled to the second jaw 820 so that one end thereof is separated from the second hinge shaft 825 by a predetermined distance, and thus the operation method of the first rotating rod 890 described above is used. And the second jaw 820 can be rotated.

Needless to say, the fixing means 858 can move in a direction perpendicular to the extending direction of the second rotating rod 895 and can be embodied and expressed by various structures such as a stopper and a latch.

  Further, a part of the first rotating rod 890 and / or the second rotating rod 895 can be formed by a spring 853. The spring 853 is a helical spring and can act to absorb and buffer impact energy. As described above, when a part of the first rotating rod 890 and / or the second rotating rod 895 is formed by the spring 853, the shock is buffered by the spring 853 when the thickness of the target suture site changes. Thus, the suture site can be prevented from being damaged, and a constant pressure for clamping can be maintained. A part of the main rod 850 can also be formed by the spring 853.

  The shape in which the main rod 850, the first rotating rod 890, and the second rotating rod 895 are accommodated in the shaft 830 can be implemented in various ways. Referring to FIG. 15, which is a cross-sectional view taken along the line KK ′ of FIGS. 13 and 14, the shaft 830 is a tubular shape that is entirely open, and includes a main rod 850 and a first rotating rod 890. In addition, the second rotating rod 895 can be realized by the shape A accommodated in the shaft 830. Referring to FIG. 15B, the shaft 830 is a tubular shape that is entirely open, and the main rod 850 is axially disposed to accommodate the first rotating rod 890 and the second rotating rod 895. Another extending groove is formed, and the first rotating rod 890 and the second rotating rod 895 are accommodated in each groove and can move in the axial direction of the shaft 830.
