[0060] Figure 1 1 is a front view showing an operating unit 100 and a driving unit 200 of a surgical instrument 10 according to an embodiment of the present invention. Figure 2 It is shown Figure 1 FIG. 1 is a front view of a state in which the operation portion 100 and the driving unit 200 are separated. Figure 3 yes Figure 1 A cross-sectional view of Figure 4 yes Figure 2 sectional view of .

[0061] See also Figures 1 to 4 According to an embodiment of the present invention, a surgical instrument 10 may include an operating portion 100 and a driving unit 200 .

[0062] The operation part 100 is provided with an interface that can be directly controlled by the doctor, for example, it is configured in a clip shape, a rod shape, a lever shape, etc. When the doctor controls the interface, the end tool (not shown) connected to the corresponding interface and inserted into the body of the surgical patient performs a predetermined operation, thereby performing surgery. Here, the operation part 100 is shown as a shape equipped with a handle 130 and a control rod 140, but the spirit of the present invention is not limited thereto, and the operation part 100 can have various forms, which is connected to the end tool (not shown) to be able to operate the end tool (not shown).

[0063] On the other hand, an end tool connection portion 110 connected to an end tool (not shown) may be formed at one end of the operating portion 100, and the other end of the operating portion 100 may include a coupling area 120, to which a driving unit 200 providing driving force for the movement of the end tool may be detachably coupled.

[0064] The coupling area 120 may be formed in a groove shape having a depth in one direction in one area of ​​the outer surface of the operation portion 100, and the coupling area 120 of the operation portion 100 may include a coupling groove 121 formed so that the drive unit 200 is accommodated in at least one area in one direction. That is, when the drive unit 200 is coupled with the operation portion 100, the drive unit 200 may be completely introduced into the inside of the operation portion 100, but in order to easily remove the drive unit 200, the drive unit 200 may be accommodated and coupled to the coupling groove 121 of the operation portion 100 only in part.

[0065] For example, see again Figure 2 , the driving unit 200 may be divided into a first area 210a and a second area 210b as other areas, wherein the first area 210a is accommodated and coupled to the coupling area of ​​the operation portion 100. That is, when the driving unit 200 is detached from the operation portion 100, the first area 210a as a portion not inserted into the coupling groove 121 can be easily grasped.

[0066] The drive unit 200 is used to supply power to the operating part 100 or transmit the driving force to the end tool (not shown). On the other hand, when the surgical instrument 10 is sterilized for reuse, the internal components of the drive unit 200 will be affected, and in particular, if the components are batteries or motors, the risk of damage is high. Therefore, after the operating part 100 as the main body of the surgical instrument 10 is sterilized, when the drive unit 200 including the battery and the like is combined and used as a separate component in a manner of being assembled to the operating part 100, the risk of damage to the drive unit 200 including the battery and the like can be minimized. The present invention is intended to solve the above-mentioned problem, and is characterized in that it includes a drive unit 200 that can be separated from or combined with the operating part 100.

[0067] The drive unit 200 may include a container 210 and a battery pack 220, wherein the container 210 is detachably formed on the operating part 100, and the battery pack is formed to be inserted into the container 210. Here, the container 210 is used together with surgical instruments in at least one surgical procedure, and may be sterilized to ensure the safety of the surgery. In the following, in order to make the description easier to understand, the container 210 is exemplarily described as a sterilized container 210 for description.

[0068] Hereinafter, the sterilization container 210 will be described in detail.

[0069] Figure 5 It is shown Figure 1 A perspective view of an alternative embodiment of a drive unit 200 of a surgical instrument 10, Figure 6 Yes Figure 5 A perspective view of a drive unit 1200 with a sterile container 1210 and a battery pack 1220 separated is shown.

[0070] See also Figures 5 and 6 In one embodiment of the present invention, the sterilization container 1210 may include a receiving portion 1212 for receiving the battery pack 1220 and a cover portion 1211 for closing the receiving portion 1212 .

[0071] The accommodating portion 1212 has a space capable of accommodating the entire battery pack 1220, and is formed so that after the battery pack 1220 is fully inserted into the sterilization container 1210, the battery pack 1220 does not protrude outside the accommodating portion 1212, but the spirit of the present invention is not limited to this. As needed, the top of the battery pack 1220 protrudes from the top of the accommodating portion 1212, and the cover portion 1211 can be formed into a dome-shaped curved shape so as to accommodate the protruding portion of the battery pack.

[0072] The cover 1211 can be opened and closed in a state where one end of the main body of the cover 1211 is combined with one end of the receiving portion 1212 of the sterilization container 1210. In other words, a hinge 1211a is formed at one end of the cover 1211 so that the cover 1211 can rotate around the hinge 1211a and can close or open the receiving portion 1212.

[0073] The sterilization container 1210 may have various shapes. Specifically, the sterilization container 1210 may have various shapes for inserting the battery pack 1220.

[0074] For example, when the sterilization container 1210 is divided into a first area 1210a near the opening of the sterilization container 1210 and a second area 1210b adjacent to the first area, the width of at least one area in the first area 1210a may be greater than that of the second area 1210b. Specifically, the width of the top of the first area 1210a and the area near the opening may be greater than the width of the second area 1210b.

[0075] As an optional embodiment, the first region 1210 a may have a plurality of regions with different widths, and the width of the top of the first region 1210 a may be greater than the width of the first region 1210 a adjacent to the second region 1210 b .

[0076] In addition, the shape of the sterilization container 1210 may be a structure in which at least one region inside the opening for inserting the battery pack 1220 becomes narrower. For example, the width of at least one region or the entire region of the first region 1210a may become narrower as it approaches the second region 1210b.

[0077] As a specific example, as shown in the figure, the first region 1210a may be formed to have a width that gradually decreases in a direction toward the second region 1210b. As an example, an inner surface of the first region 1210a may include an inclined surface.

[0078] Further, the disinfection container 1210 may have the following shape: from the opening for inserting the battery pack 1220 to all areas inside, the more narrow it is toward the bottom. That is, it may be formed into the following shape: when the direction from the top of the disinfection container 1210 combined with the cover 1211 toward the bottom of the disinfection container 1210 as the bottom surface of the accommodating portion 1212 is defined as the positive direction, that is, the insertion direction of the battery pack 1220, the disinfection container 1210 may be formed to become narrower toward the positive direction. For example, the shape of the disinfection container 1210 may be funnel-shaped, conical, trapezoidal, etc. Of course, the spirit of the present invention is not limited thereto, and disinfection containers of various shapes that facilitate the insertion of the battery pack are possible.

[0079] In the surgical instrument 10 according to an embodiment of the present invention, when the battery pack 1220 is inserted into the sterilization container 1210, since the entrance of the accommodating portion 1212 of the sterilization container 1210 is wider than the width of the battery pack 1220, the insertion of the battery pack 1220 can be easy, and since the sterilization container 1210 has a structure that becomes narrower toward the positive direction, the battery pack 1220 is guided and installed along the inclined surface S on the side of the sterilization container 1210, and the center part of the battery pack 1220 can be naturally aligned toward the center of the sterilization container 1210.

[0080] (See Figure 7B )

[0081] On the other hand, hospitals keep operating rooms sterile to prevent infection of patients, and strict management is also required for the disinfection and sterilization of medical personnel and surgical instruments. Therefore, in the medical device industry, especially in the surgical instrument industry, maintaining the sterilization of surgical instruments is an important task.

[0082] Therefore, for the use of surgical instruments, it is important to prevent the sterilization container from being contaminated during the process of inserting an unsterilized battery pack into the sterilization container. As described above, the sterilization container according to one embodiment of the present invention adopts a structure that is easy to insert the battery pack, thereby reducing the possibility of contamination due to user error. That is, the battery pack can be easily inserted into the sterilization container, so that the outer surface of the container in a sterilized state will not be contaminated by the unsterilized battery pack.

[0083] FIG. 7A to FIG. 7B It is shown Figure 1 A perspective view and a cross-sectional view of another optional embodiment of a drive unit 200 of a surgical instrument 10 are shown. FIG. 8A to FIG. 8D The battery pack 2220 is shown inserted into FIG. 7A to FIG. 7B A perspective view of a process in a sterilized container 2210 and a locking structure 2213 of the sterilized container 2210.

[0084] See also Fig. 7A and Figure 7B as well as FIG. 8A to FIG. 8D In one embodiment of the present invention, the sterilization container 2210 may further include a locking structure 2213 .

[0085] Specifically, a structure protruding toward the cover 2211 is formed at the top of the side of the sterilization container 2210, and a locking groove 2214 can be formed on the cover 2211 at a position corresponding to the locking structure 2213, which can be combined with the locking structure 2213. Here, the locking structure 2213 is combined with the locking groove 2214 to prevent the cover 2211 from opening.

[0086] Further, the locking structure 2213 may have a structure that is damaged when an external force exceeding a preset certain level is applied. Specifically, when an external force exceeding the weight of the battery pack 2220 is applied, the locking structure 2213 may be damaged. Specifically, when an external force is applied in the direction of closing the cover 2211, the locking structure 2213 may be easily deformed, but when an external force is applied in the direction of opening the cover 2211, the locking structure 2213 may be damaged. In other words, the locking structure 2213 is built with a predetermined structure, which can be easily folded in the insertion direction (positive direction) of the battery pack 2220, and when the sealed cover 2211 is opened in the opposite direction of removing the battery pack 2220, the predetermined opening and closing structure is damaged, which may cause the cover 2211 of the sterilization container 2210 to be unable to be sealed, so that the sterilization container 2210 cannot be reused. As described above, the locking structure 2213 is formed as an irreversible opening and closing structure, so that the sterilization container 2210 can be formed as a non-reusable disposable consumable, but the spirit of the present invention is not limited to this, and in order to only use it a preset specified number of times, a sterilization container with a limited number of uses can also be used.

[0087] In addition, one or more locking structures 2213 may be provided, and are not necessarily limited to being formed on FIG. 7A to FIG. 7B Position shown.

[0088] On the other hand, another embodiment related to the apparatus for sterilizing the non-reusable container 210 is described.

[0089] Fig. 9 It is shown Figure 1 A cross-sectional view of yet another optional embodiment of a drive unit 200 for a surgical instrument 10. Fig.10 The cover 3211 is connected to Fig. 9 A cross-sectional view of a sterilization container 3210 is shown.

[0090] See also Fig. 9 and Fig.10 In one embodiment of the present invention, the disinfection container 3210 may further include a fastening portion 3215, which is used to support and fix the battery pack 3220 inside the accommodating portion 3212, and a fastening groove 3221 may be formed on the battery pack 3220 at a position corresponding to the fastening portion 3215.

[0091] The fastening portion 3215 is formed to protrude toward the inside of the accommodating portion 3212, but when the battery pack 3220 is inserted into the accommodating portion 3212 of the sterilizing container 3210, the fastening portion 3215 of the sterilizing container 3210 may be deformed in a predetermined manner due to elasticity. Therefore, when the battery pack 3220 moves in the positive direction, the battery pack 3220 can be easily inserted into the accommodating portion 3212 without being caught by the fastening portion 3215. On the contrary, when the battery pack 3220 is fully inserted into the accommodating portion 3212 and the fastening portion 3215 of the sterilizing container 3210 is inserted into the fastening groove 3221 of the battery pack 3220, the battery pack 3220 is stably supported and fixed and cannot move in the opposite direction.

[0092] In addition, the battery pack 3220 may be a structure in which the fastening groove 3221 is omitted. In this case, in a state where the battery pack 3220 is completely introduced into the sterilization container 3210, the fastening portion 3215 is caught on the end of the battery pack 3220, thereby supporting and fixing the battery pack 3220.

[0093] In addition, the structure of the fastening portion 3215 can be damaged when a set condition is reached, that is, when an external force exceeding a preset certain level is applied. Specifically, when an external force exceeding the weight of the battery pack 3220 is applied, the fastening portion 3215 may be damaged. In detail, when an external force is applied in a direction opposite to the insertion direction of the battery pack 3220, the fastening portion 3215 may be damaged. In other words, when the fastening portion 3215 is combined with the fastening groove 3221, the movement of the battery pack 3220 in the opposite direction is restricted. Unless there are special circumstances, the external force equivalent to the weight of the battery pack 3220 cannot damage the fastening portion 3215, but if an external force exceeding the weight of the battery pack 3220 is applied, the fastening portion 3215 is damaged, so that the battery pack 3220 can be drawn out of the accommodating portion 3212.

[0094] In addition, since the sterilization container 3210 with the fastening portion 3215 damaged cannot stably support and fix the battery pack 3220, it cannot be used anymore.

[0095] As described above, the fastening portion 3215 is formed into an irreversible structure, so that the sterilization container 3210 can be formed into a non-reusable disposable consumable, but the spirit of the present invention is not limited to this, and in order to only use it for a preset specified number of times, a sterilization container with a limited number of uses can also be used.

[0096] Finally, when the procedure is complete, the reusable battery pack 3220 is separated from the sterilization container 3210 and recharged, while the sterilization container 3210 is separately separated and discarded.

[0097] On the other hand, methods for inserting the battery pack 220 in an unsterilized state into the sterilized container 210 include a method using an automatic insertion type charger and a direct fastening method, and a charger for charging the battery pack will be described in detail later.

[0098] Fig.11 FIG. 2 is a perspective view showing a state in which the driving unit 200 is separated in the surgical instrument 20 according to an embodiment of the present invention.

[0099] The surgical instrument 20 may include an operation portion 1100 , a driving unit 1200 , an end tool connecting portion 1110 , and an end tool 1300 .

[0100] The end tool connection part 1110 is formed in a hollow shaft shape, and one or more wires and electric wires can be accommodated therein. The operation part 1100 is coupled to one end of the end tool connection part 1110, and the end tool 1300 is coupled to the other end of the end tool connection part 1110, so that the end tool connection part 1110 can be used to connect the operation part 1100 and the end tool 1300.

[0101] The end tool 1300 can be connected to an area of ​​the surgical instrument 20, such as the end, so as to be inserted into the surgical site to perform the required operation. In addition, as an example, the end tool 1300 can be connected to the operating part 1100, and as a specific example, the end tool 1300 can be connected to the operating part 1100 through one or more connecting parts 1110, so as to drive the end tool 1300 by operating the operating part.

[0102] exist Fig.11 In the figure, it is shown that the end tool that can perform the function of a surgical stapler is combined here, but the present invention is not limited to this, and various end tools can be combined here as surgical instruments. Fig.11 Stapler tip tool shown.

[0103] Meanwhile, the drive unit is shown as Figure 5 The driving unit 1200 is, but is not limited thereto, and of course, the driving units of other embodiments described above may also be applied.

[0104] Hereinafter, other features related to the sterilization container 1210 in the surgical instrument 20 according to an embodiment of the present invention will be described in more detail.

[0105] The sterilization container 1210 may be a polymer of a rigid material that can maintain an opaque or transparent shape.

[0106] An ID chip 1216 is built into the interior or exterior of the sterilization container 1210 , and the operation unit 1100 may include an identification unit that contacts the ID chip 1216 .

[0107] In one embodiment, the surgical instrument 20 is equipped with a predetermined physical contact structure between the operating part 1100 and the ID chip 1216 of the sterilization container 1210. When they are not physically completely fastened, the operating part 1100 is not in contact with the ID chip 1216, thereby making the system operation impossible.

[0108] And when the sterilization container 1210 is coupled to the operating part 1100, the ID chip 1216 contacts the identification part of the operating part 1100, and at the same time, the preset system can be operated. This means that when the battery pack 1220 is inserted into the coupling area of ​​the operating part 1100, the system power is turned on (System Power ON) and the status check (Status check) is started. For example, the product can be operated by the ID chip 1216 and various information such as authenticity authentication, LOT and serial number, and whether it can be reused can be provided.

[0109] In addition, the ID chip 1216 can transmit data to the operation unit 1100 through passive radio frequency identification sensing technology (Passive RFID) that does not require power.

[0110] Fig.12 1 is a perspective view showing a charging state of a battery pack 220 of a surgical instrument 10 according to an embodiment of the present invention, FIG. 13A to FIG. 13C It is shown Fig.12 FIG. 2 is a diagram of a process of inserting a battery pack 2220 into a sterilization container 2210 according to a specific embodiment.

[0111] The automatic insertion type charger 2400 (hereinafter referred to as the charger) may include a charging device 2420 including a charger terminal 2421 that charges the battery by contacting the charging terminal of the battery pack 2220, and a support portion 2410 that protrudes a certain area at the outer edge of the charging device 2420 to support and fix the battery pack 2220. Here, the support portion 2410 may be a structure that detaches the battery pack 2220 when a certain pressure is applied.

[0112] Specifically, the battery pack 2220 may include a protrusion 2223 protruding toward the charging device 2420, and the support portion 2410 may be a structure including a latch member 2411, the latch member 2411 is pressed by the protrusion 2223 to be coupled with or released from the protrusion 2223, and an elastic member 2412 presses the latch member 2411 from the inside to the outer edge direction of the charging device 2420. In other words, when the latch member 2411 provided in the charging device 2420 is pressed by the protrusion 2223 and moves inward, the latch member 2411 may grip the protrusion 2223, whereby the battery pack 2220 may be fixed to the charging device 2420 for charging. Furthermore, when the latch member 2411 is pressed again to move, the latch member 2411 is moved toward the outer edge by the elastic member 2412 , whereby the protrusion 2223 clamped by the latch member 2411 is released and the battery pack 2220 can be separated from the charging device 2420 .

[0113] Describing this from another perspective, after the sterilization container 2210 is set, the sterilization container 2210 is moved so that the battery pack 2220 is fully inserted into the sterilization container 2210, so that the battery pack 2220 placed on the charging device 2420 and fixed can be inserted into the sterilization container 2210 in the positive direction, and then in the state where the battery pack 2220 is inserted, a certain pressure is applied to the sterilization container 2210 in the positive direction, so that the battery pack 2220 can be automatically removed from the support portion 2410.

[0114] In addition to the automatic insertion method, the direct fastening method may be a method of holding a handle (not shown) provided on the battery pack 2220 that has completed charging, inserting the battery pack 2220 into the sterilized container 2210, and then closing the cover 2211. At this time, a person in the non-sterile area may carry the battery pack 2220, inserting the battery pack 2220 into the sterilized container 2210 held by a person in the sterilized area.

[0115] Hereinafter, a surgical instrument 30 according to another embodiment of the present invention will be described.

[0116] Fig.14 FIG. 1 is a diagram showing a surgical instrument 30 according to another embodiment of the present invention.

[0117] See also Fig.14 , the driving unit 4200 may be a battery pack itself for supplying power to the operating unit 4100 .

[0118] That is, here, the driving unit 4200 may be a disposable battery pack itself, which is different from the battery pack 220 inserted into the sterilization container 210 .

[0119] When equipped with a disposable battery pack, the battery pack is directly inserted into the coupling area 4120 or the coupling groove 4121 of the operating part 4100 that has been sterilized before surgery.

[0120] Similar to the reusable battery pack 220 , the disposable battery pack has an ID chip built into the outside, so that when it is inserted into the operation unit 4100 , the authenticity authentication and the number of times it has been used can be identified.

[0121] In one embodiment, the surgical instrument 30 is equipped with a predetermined physical contact structure between the operating part 4100 and the ID chip of the driving unit 4200. When they are not physically completely fastened, the operating part 4100 is not in contact with the ID chip, thereby making the system operation impossible.

[0122] And when the drive unit 4200 is coupled to the operating part 4100, the ID chip contacts the identification part of the operating part 4100, and at the same time, the preset system can be operated. This means that when the drive unit 4200 is inserted into the coupling area 4120 of the operating part 4100, the system power is turned on (System Power ON) and the status check (Status check) is started. For example, the product can be operated by the ID chip and various information such as genuine authentication, LOT and serial number, and whether it can be reused can be provided.

[0123] The ID chip can transmit data to the operating unit 4100 through passive radio frequency identification sensing technology (Passive RFID) that does not require power.

[0124] Hereinafter, a distal end tool of a surgical instrument according to an embodiment of the present invention will be described in detail.

[0125] Fig.15 and Fig.16 It is shown Fig.11 A perspective view of the end tool of a surgical instrument. Fig.17 It is shown Fig.11 A side view of the end tool of a surgical instrument. Fig.18 It is shown Fig.11 An exploded perspective view of the end tool of a surgical instrument.

[0126] The end tool 1300 is formed at the other end of the connection part 1110 and is inserted into the surgical site to perform the required operation. As an example of the end tool 1300 as described above, Fig.11A pair of jaws 1303 is shown for gripping. However, the spirit of the present invention is not limited thereto, and various surgical devices may also be used as the end tool 1300. For example, a configuration such as a single-arm cauterizer may also be used as the end tool 1300. The end tool 1300 as described above is connected to the operating part 1100 through a power transmission part (not shown), and receives the driving force of the operating part 1100 through the power transmission part (not shown), thereby performing the actions required for the operation, such as gripping, cutting, and suturing actions.

[0127] Here, the end tool 1300 of the surgical instrument 20 according to an embodiment of the present invention is formed to be rotatable in one or more directions. For example, the end tool 1300 can be formed to surround Fig.11 While the Y axis is pitching, Fig.11 The Z-axis performs yaw motion and actuation motion.

[0128] The power transmission part (not shown) connects the operation part 1100 and the end tool 1300 to transmit the driving force of the operation part 1100 to the end tool 1300, and may include a plurality of wires, pulleys, links, joints, gears, etc.

[0129] In addition, the end tool 1300 may include pulleys 1311, 1312, 1313, 1314, 1315, and 1316 associated with the rotational movement of the first jaw 1301. In addition, pulleys 1321, 1322, 1323, 1324, 1325, and 1326 associated with the rotational movement of the second jaw 1302 may be included.

[0130] Here, although the drawings show that the pulleys facing each other are formed in parallel, the spirit of the present invention is not limited thereto, and the pulleys can be formed at various positions suitable for the configuration of the end tool and can also be formed into various sizes suitable for the configuration of the end tool.

[0131] In addition, an end tool 1300 according to the first embodiment of the present invention may include an end tool center 1380 and a pitch center 1307 .

[0132] The rotating shaft 1341 and the rotating shaft 1342 described later are inserted through the end tool center 1380, and at least a portion of the pulley 1311 and the pulley 1321, the shafts of which are coupled to the rotating shaft 1341, can be accommodated inside the end tool center 1380. In addition, the end tool center 1380 can accommodate at least a portion of the pulley 1312 and the pulley 1322, the shafts of which are coupled to the rotating shaft 1342, inside.

[0133] On the other hand, a pulley 1331 used as an end tool pitch pulley may be formed at one end of the end tool center 1380. Fig.15 As shown, the pulley 1331 and the end tool center 1380 may be formed as one-body. That is, a disk-shaped pulley is formed at one end of the end tool center 1380, and a groove on which a wire can be wound may be formed on its outer circumference. Alternatively, the pulley 1331 may be formed as a separate member separated from the end tool center 1380 and combined with the end tool center 1380. The wires 1403 and 1404 are combined with the pulley 1331 used as the end tool pitch pulley, and the pulley 1331 performs a pitching motion while rotating around the rotation axis 1343.

[0134] The rotation axis 1343 and the rotation axis 1344 described later are inserted through the pitch center 1307, and the pitch center 1307 and the end tool center 1380 (and the pulley 1331) are axially coupled via the rotation axis 1343. Therefore, the end tool center 1380 and the pulley 1331 can be formed to be rotatable around the rotation axis 1343 relative to the pitch center 1307.

[0135] The pulley 1311 and the pulley 1321 as the end tool jaw pulleys are formed to face each other and are formed to be independently rotatable around the rotation axis 1341 as the end tool jaw pulley rotation axis. At this time, the pulley 1311 and the pulley 1321 can be formed to be spaced a certain distance apart so that the suture nail assembly accommodating portion can be formed between them. In addition, at least a portion of the suture nail pulley assembly 1360 and the suture nail link assembly 1370 described later can be set in the suture nail assembly accommodating portion.

[0136] The first jaw 1301 is formed as a whole in the shape of an elongated rod, and is formed to accommodate the nail magazine 1500 at the distal end side, and is combined with the pulley 1311 at the proximal end so as to be rotatable around the rotation axis 1341. In other words, the first jaw 1301 is formed as a whole in the form of an empty box with one side (top surface) removed, so that a nail magazine accommodating portion that can accommodate the nail magazine 1500 can be formed inside the first jaw 1301. That is, the cross section of the first jaw 1301 can be formed roughly in a "U" shape. The nail magazine as described above will be described in detail later.

[0137] See also Figures 15 to 18 Etc., the end tool 1300 may include a staple pulley 1361 and a staple auxiliary pulley 1362 associated with the linear / rotational motion of each pulley and link for staple stapling and cutting.

[0138] The staple pulley 1361 is formed to face the pulley 1311 and the pulley 1321 as the end tool jaw pulleys, and is formed to be independently rotatable around the rotation axis 1341 as the end tool jaw pulley rotation axis. Here, although the drawings show that the staple pulley 1361 is disposed between the pulley 1311 and the pulley 1321, the spirit of the present invention is not limited thereto, and the staple pulley 1361 may be disposed at various positions adjacent to the pulley 1311 or the pulley 1321.

[0139] Here, a feature of the present invention is that the staple pulley 1361, pulley 1311 and pulley 1321 are formed to rotate substantially around the same axis. As described above, the staple pulley 1361, pulley 1311 and pulley 1321 are formed to rotate around the same axis, so that the staple suturing and cutting actions can be performed while performing the pitch motion / yaw motion / actuation action. However, although the staple pulley 1361, pulley 1311 and pulley 1321 are formed to rotate around a rotation axis 1341 in the accompanying drawings, each jaw pulley can of course also be formed to rotate around a separate axis concentric with each other.

[0140] On the other hand, the end tool 1300 of the first embodiment of the present invention may further include a staple link assembly 1370 connected to the staple pulley assembly 1360. The staple link assembly 1370 may include one or more link members 1371. The staple link assembly 1370 may be used to connect the staple pulley assembly 1360 and the reciprocating assembly 1550 of the staple cartridge 1500 described later. In this embodiment, it is assumed that the staple link assembly 1370 includes one link member 1371, and the link member 1371 includes a first link 1372 and a second link 1373.

[0141] When the staple pulley 1361 rotates in the clockwise direction, the link member 1371 connected to the staple pulley 1361 can move as a whole toward the distal end of the first jaw 1301. Conversely, when the staple pulley 1361 rotates in the counterclockwise direction, the link member 1371 connected to the staple pulley 1361 can move as a whole toward the proximal end of the first jaw 1301.

[0142] Therefore, the bidirectional rotational motion of staple pulley assembly 1360 causes the reciprocating linear motion of reciprocating moving assembly 1550 of staple cartridge 1500 via staple link assembly 1370 .

[0143] In the following, it will be described in more detail Fig.11 A nail magazine 1500 of a surgical instrument 20.

[0144] Fig.19 It is shown Fig.15 An exploded perspective view of the nail magazine. Fig. 20 It is shown Fig.11 A side sectional view of a staple-suturing-related structure of an end tool of a surgical instrument, Fig.21 It is shown Fig. 20 A perspective view of the ratchet drive action of the end tool.

[0145] The staple cartridge 1500 is formed to be attachable to and detachable from the first jaw 1301, and includes a plurality of staples 1530 and a blade 1542 inside for suturing and cutting tissue. Here, the staple cartridge 1500 may include a cover 1510, a housing 1520, staples 1530, a lead-out member 1535, a working member 1540, and a reciprocating assembly 1550.

[0146] The shell 1520 constitutes the outer shape of the nail magazine 1500, and is generally formed in a shape of an empty box with one side (top surface) removed, so that the interior thereof can be formed to accommodate the reciprocating movement assembly 1550, the working member 1540 and the suture nails 1530.

[0147] The cover 1510 is formed to cover the top of the housing 1520. The cover 1510 may be formed with a suture nail hole 1511 that allows a plurality of suture nails 1530 to be discharged to the outside. Before the suture nailing drive, the suture nails 1530 are originally accommodated in the interior of the housing 1520, but when the suture nailing action is performed, the suture nails 1530 are pushed upward by the working member 1540, and then pass through the suture nail holes 1511 of the cover 1510 to be led out to the outside of the nail magazine 1500, and the suture nailing is performed.

[0148] On the other hand, the slit 1512 may be formed on the cover 1510 along the length direction of the cover 1510. The blade 1542 of the working member 1540 may protrude to the outside of the staple cartridge 1500 through the slit 1512. When the blade 1542 of the working member 1540 passes along the slit 1512, the stapled tissue may be cut.

[0149] In addition, a plurality of suture staples 1530 may be disposed inside the housing 1520. As the working member 1540 described later moves linearly in one direction, the plurality of suture staples 1530 are sequentially pushed upward from the inside of the housing 1520 to the outside while suturing, i.e., staple suturing. Here, the material of the suture staples 1530 may include titanium, stainless steel, etc.

[0150] On the other hand, a lead-out member 1535 may be further provided between the housing 1520 and the staples 1530. In other words, it may be described that the staples 1530 are provided on top of the lead-out member 1535. In this case, the working member 1540 pushes the lead-out member 1535 upward while linearly moving in one direction, and the lead-out member 1535 may push each staple 1530 upward.

[0151] The reciprocating assembly 1550 may be disposed below the interior of the housing 1520. The reciprocating assembly 1550 may include one or more reciprocating members 1551. In this embodiment, although one reciprocating member 1551 is shown, a plurality of reciprocating members 1551 may be provided in the embodiments described later.

[0152] In the present embodiment, the reciprocating member 1551 may be a rack. The reciprocating member 1551 may include a concave-convex portion 1551b and a fastening portion 1551a. In detail, the reciprocating member 1551 may be formed in the shape of a long bar, and a plurality of concave-convex portions 1551b in a sawtooth shape may be formed on one surface thereof. The concave-convex portion 1551b may be formed to be contactable with the working member 1540 described later, in particular, to be contactable with the ratchet member 1543 of the working member 1540. In other words, the reciprocating member 1551 may include a plurality of concave-convex portions 1551b having a shape that meshes with the respective ratchets 1543a of the ratchet member 1543.

[0153] On the other hand, although not shown in the drawings, in addition to the shape of a rack, the reciprocating member 1551 may be provided as a member of various shapes directly or indirectly connected to the staple pulley assembly 1360 so as to be able to perform linear reciprocating motion according to the rotational motion of the staple pulley assembly 1360. For example, the reciprocating member 1551 may be in the form of a clutch without a concave-convex portion.

[0154] On the other hand, the working member 1540 may be disposed inside the housing 1520. The working member 1540 is formed to be contactable with the reciprocating member 1551, so that it can perform linear motion in one direction according to the reciprocating linear motion of the reciprocating member 1551. In other words, the working member 1540 interacts with the reciprocating member 1551, so that the stapling and cutting are performed while moving along the extending direction of the connecting portion 1100.

[0155] Hereinafter, a stapling action of a surgical instrument according to an embodiment of the present invention will be described.

[0156] FIG. 22A to FIG. 22C It is shown as a whole Fig. 20A perspective view of the stapling action of the end tool.

[0157] See also FIG. 22A to FIG. 22C ,exist Fig.22A In the state shown, when the working member 1540 moves along Fig. 22B When moving in the direction of arrow A1 in FIG. 1 , the wedge 1541 of the working member 1540 pushes the lead-out member 1535 upward, and the lead-out member 1535 pushes the lower side of the suture staple 1530 upward. In addition, thereby, the suture staple 1530 is discharged to the outside of the first jaw 1301 and the staple cartridge 1500.

[0158] In this state, when the working member 1540 moves along Fig. 22C When the suture staple 1530 moves further in the direction of arrow A2, the ejected suture staple 1530 is further pushed upward by the working member 1540 while in contact with the anvil 1302a of the second jaw 1302, so that the two ends of the suture staple 1530 are bent to perform suture suturing.

[0159] While the above-mentioned operation is continuously performed, the suture is performed sequentially from the suture staples 1530 on the proximal end portion 1501 side to the suture staples 1530 on the distal end portion 1502 side.
