A medical clip may be used for gripping or excising a human body organ extending in a longitudinal direction such as a blood vessel or an appendix during a surgical procedure inside the human body. Clips are used, for example, to grip, ligate, or to halt the appendix or blood vessels during appendectomy. Such medical clips may be made of, for example, a resilient metal or polymer material. For the ligation of body parts such as blood vessels or parts of the appendix during surgery, a plurality of clips may be sequentially arranged and used in the apple liar. In addition, before using the clip, the apple liar may be sterilized or sterilized or left for a long time. When the Apple Liar is in such a state, physical properties such as elasticity of the clip disposed therein may be changed, and thus, the clip may be released in the process of being transferred to the jaw unit disposed at the end of the Apple Liar and used. In addition, since multiple clips are continuously arranged in the supply tube of the Apple Liar, the clips disposed at the rear may change physical properties over time. Therefore, there is a need for a clip apple liar that maintains the physical properties of the clip before use and can be stably used in the surgical process.

The present invention will be described in detail below with reference to the embodiments presented in the accompanying drawings, but the embodiments are intended for a clear understanding of the present invention and the present invention is not limited thereto. In the following description, components having the same reference numerals in different drawings have similar functions, and are not described repeatedly unless necessary for understanding of the invention, and well-known components are briefly described or omitted, but the present invention It should not be understood as being excluded from the embodiment.

1 shows an embodiment of a clip apple liar according to the present invention.

Referring to FIG. 1, the medical clip applier includes a trigger module 11 for moving a clip; A movement control module 12 disposed inside the trigger module 11; A guide channel 13 that guides movement of the clip while at least one clip is aligned; And a clip jaw 14 coupled to the front side of the guide channel 13, by the movement adjustment module 12 in the process of moving the clip in the clip jaw 14 by the operation of the trigger module 11 The movement of the clip is restricted at at least one point.

The apple liar according to the present invention can be applied to medical clips of various standards and can be applied to, for example, medical clips composed of two branch branches maintained at a constant angle. Medical clips can be used for ligation of blood vessels or tissues in open or laparoscopic surgery and can be made of metals or polymers such as titanium.

The trigger module 11 may have a function of a handle for handling and a housing in which a configuration for operation therein is accommodated. Specifically, the trigger module 11 may be formed of a handle 111 formed on the receiving body 16 and an operation trigger 112 that induces movement of the clip. The operation trigger 112 may be coupled to the receiving body 16 so as to be movable relative to the handle 111 formed on the receiving body 16. For example, one end of the operation trigger 112 extending in a curved shape is fixed inside the handle 111, and the operation trigger 112 may have a structure rotatable around a fixed upper end. In this way, the operation trigger 112 may function as a trigger, and the clip may be moved by the operation of the operation trigger 112, or discharged to the outside of the appler and used for ligation. The handle 111 may be integrally formed with the receiving body 16, and the guide channel 13 may be coupled to the receiving body 16 by the knob unit 15. The guide channel 13 may be a hollow linear tube structure, and a plurality of clips may be aligned therein. The clip jaw 14 is coupled to the end of the guide channel 13, and the clip jaw 14 enables ligation of a defined region of a blood vessel or a human body part by a clip. A plurality of clips aligned to the guide channel 13 can be moved to the clip jaw 14 by the operation of the trigger module 11, and the clip located at the front of the guide channel 13 is the clip jaw 14 Can be moved to. Thereafter, the clip is discharged from the clip jaw 14 by the additional operation of the trigger module 11, thereby ligating the blood vessel. Since the site to be ligated is located inside the human body, it is difficult to visually confirm the entire process of ligation. In addition, the process in which the clip is moved from the guide channel 13 to the clip jaw 14 and the process of ligation while being discharged from the clip jaw 14 is also difficult to be visually confirmed. The movement adjustment module 12 allows the movement process of the clip to be adjusted, and at the same time, the movement or ligation process can be recognized. Specifically, when the operation trigger 112 is operated for ligation, the guide channel 13 can be moved to the clip jaw 14, whereby the clip is placed in a waiting state for ligation. Further, when the operation trigger 112 is pulled in the direction of the handle 111, the clip is discharged from the clip jaw 14, and the ligation process is performed. Thereafter, when the operation trigger 112 is released, the operation trigger 112 is moved to the original position, the clip jaw 14 is closed, and a new clip of the guide channel 13 can be moved to the clip jaw 14 do. Such a clip can ligate blood vessels or human body parts through a waiting step in the guide channel 13, a waiting step in the clip jaw 14, and a ligation step by discharge. According to one embodiment of the present invention, in the moving step of the clip, the movement adjusting module 12 may limit the movement of the clip at at least one point. For example, if the clip is applied to the ligation straight from the guide channel 13 through the clip jaw 14, it is difficult for the operator to recognize the process of the ligation, and even the ligation in which the clip is not ligated out of the clip jaw 14 When an error occurs, it is difficult for the operator to recognize it. In addition, it is difficult for the operator to confirm the moving position of the clip during the ligation process. The movement adjustment module 12 limits the movement of the clip at at least one point so that the movement position of the clip is confirmed. It allows the operator to recognize the movement state of the clip. The movement adjustment module 12 causes the pressure applied to the operation trigger 112 to be significantly changed at at least one point while the operation trigger 112 is moved in the direction of the handle 111. Due to this, if the operation of the clip is temporarily changed, the movement of the clip is restricted. For example, the operation trigger 112 must be moved by applying a pressure of a predetermined level or more by hand in the direction of the handle 111 from the initial position so that the clip is moved from the guide channel 13 to the clip jaw 14. The clip may be moved according to the movement of the operation trigger 112 to be located in the clip jaw 14, and the ligation standby state. When pressure above a certain level is applied to the operation trigger 112 in the same direction, ligation is performed while the clip is discharged from the clip jaw 14. The movement adjustment module 12 allows the operation trigger to move even if the pressure applied to the operation trigger 112 is significantly reduced when the clip is completely positioned in the ligation waiting state. Conversely, if a relatively large pressure is not temporarily applied to the operation trigger 112, the operation trigger 112 may be prevented from moving. The movement of the clip is temporarily limited due to a significant change in pressure with respect to the movement of the operation trigger 112, and the operator can confirm the position of the clip. Optionally, in the process of rotating the operation trigger 112 so that the clip is moved from the guide channel 13 to the clip jaw 14, sound may be generated or vibration may be generated by the movement adjustment module 12. In addition, when the clip is just before the ligation standby state in the clip jaw 14, the occurrence of sound or vibration is interrupted, and the movement adjustment module ( No sound or vibration is generated by 12). Thereby, the operator can recognize that ligation is being performed while the clip is discharged.

In order to limit the movement of the clip or to recognize the clip position, the movement adjustment module 12 may be made of various structures.

2 shows an embodiment of a structure for controlling and recognizing the movement of a clip applied to a clip apple liar according to the present invention.

Referring to FIG. 2, the movement adjustment module 12 includes an induction unit 21 formed in the receiving body 16 of the trigger module 11; And a movement unit 22 formed on the operation trigger 112 of the trigger module 11 and moved along the induction unit 21.

A plurality of coupling pins P1 to PN may be formed inside the accommodation body 16 or the handle 111, and the sub accommodation bodies 16 facing each other may be coupled to each other by the coupling pins P1 to PN. Can. A pin hole PH that may be rotatably coupled to one engagement pin P1 may be formed in the operation trigger 112. A linear projection-shaped induction unit 21 protruding perpendicularly to the inner wall of the receiving body 16 may be formed in the upper portion of the handle 111. In addition, the mobile unit 22 may be formed to protrude from the inner edge of the operation trigger 112 to the outside of the operation trigger 112. The operation trigger 112 may be rotated around the pin hole PH, and in the process of being rotated, the end of the mobile unit 22 may contact the height surface of the induction unit 21.

2 is a side view and a front view of the induction unit 21, respectively. The guiding unit 21 includes a linear guiding portion 211 extending in a curved shape or a linear shape having a large radius of curvature as a whole; And a limiting groove 212 formed in the thickness direction in the middle portion of the linear guide portion 211. In addition, the lower portion of the restriction groove 212 may include a recognition unit 213 made of a linear locking projection continuously formed on the inner wall. The linear guide portions 211 may have different heights extending upwards, and the limiting grooves 212 may be formed to be V-shaped from the inner side of the inner wall. 2 is a plan view and a front view of the mobile unit 22, respectively. The mobile unit 22 includes a vibration base 221 extending in a plate shape having a constant width in the direction of the induction unit 21 in the state in which the operation trigger 112 is coupled; And first and second contact portions 222 and 223 formed at the ends of the vibration base 221. The vibration base 221 may have a shape that gradually decreases in thickness along the extension direction, and the first and second contact portions 222 and 223 may be extended to a short length while having a larger width than the vibration base 221. The second contact portion 223 may be integrally formed with the vibration base 221, and the first contact portion 222 may have a greater thickness or height than the vibration base 221 or the second contact portion 223. The first and second contact portions 222 and 223 may thereby form a step surface. In the process of moving the mobile unit 22 along the induction unit 21, the second contact portion 223 may contact the inner surface or the outer surface of the induction unit 21. When the rotation of the operation trigger 112 is started, the second contact portion 223 may be moved from the lower side of the inner surface of the induction unit 21 (M1 direction). In the process of moving in the M1 direction, the second contact portion 223 may generate sound as vibration is generated by a plurality of linear locking protrusions formed in the recognition unit 231. Thereby, the operator can recognize that the clip is moving from the guide channel to the clip jaw. When the limiting groove 212 is reached after the second contact portion 223 is moved along the M1 direction, movement of the operation trigger 112 is temporarily stopped, and the clip is positioned in the clip jaw from the channel guide. As it is located in the second contact portion 223 in the restriction groove 212, the operation of the operation trigger 112 is temporarily limited, and the operator can recognize this, and at the same time, confirm the position of the clip. Subsequently, when a strong pressure is temporarily applied to the operation trigger 112, the second contact portion 223 moves along the M2 direction, and thus, the clip is discharged from the clip jaw, so that ligation may be performed. When the ligation is performed in this way, the operation trigger 112 may return to the original direction again. During the restoration process, the first contact portion 222 may contact the outer surface of the linear guide portion 211 and may be moved along the direction indicated by M3. When the operation trigger 112 returns to the original direction, the process described above may be repeated again.

Referring to FIG. 3, the operation trigger 112 may be rotatably coupled to one engagement pin P1, and the operation trigger 112 may be operated in the form of approaching or moving away from the handle 111. The left side of FIG. 2 shows the state in which the clip is completed, and the right side of FIG. 2 shows the state in which the operation trigger 112 discharging the clip is restored to the original position. In the course of discharging the clip, the first contact portion 222 is moved along the front face of the linear guide portion 211, and is temporarily stopped in the restriction groove 212 formed on the front face. Thereafter, when the clip is discharged, the first contact portion 222 may be moved in contact with the rear surface of the linear guide portion 211 to return to the original position.

The process of discharging the clip is described below.

4A and 4B, the operation trigger 112 may be ligated while being discharged after the clip is moved to the clip jaw 14 while approaching the direction of the handle 111. In addition, the clip jaw 14 includes a connecting portion 141 coupled to the guide channel; A jaw unit 142 coupled to the connecting portion 141; And a pressing unit 143 disposed inside the jaw unit 142. When the operation of the operation trigger 112 is started, the clip 41 positioned at the connection portion 141 is moved forward, and as shown in (a) of FIG. 4B, the set unit 142 is opened. If the operation trigger 112 is continuously operated, the clip 41 may be located in the jaw unit 142 as shown in (b) of FIG. 3, and the movement adjustment module 12 may be operated in the same process. By this, sound or vibration may be generated. Due to the sound or vibration, the operator can recognize that the clip 41 is moving to the jaw unit 142. As described above, when the first and second contact portions are located in the restriction groove, the operation of the operation trigger 112 may be temporarily stopped. Subsequently, if the operation trigger 112 is continuously operated, it approaches the direction of the handle 111, and as shown in (c) of FIG. State. Ligation may be completed as shown in FIG. 4B (D) as the mobile unit reaches the upper end of the induction unit. Subsequently, when the operation trigger 112 is moved to the original state, the mobile unit may return to the original state along the other side of the induction unit and return to the state of FIG. 4B (a). The operation of the operation trigger 112 of the movement restriction module or the movement adjustment position of the clip 41 may be variously set and is not limited to the presented embodiment.

The clip apple liar of the clip movement adjustment structure according to the present invention is ligated from the process of moving the clip from the apple liar to the clip jaw, so that the process of discharging from the clip jaw is controlled. Also, in this process, the operator can recognize by the sense or sound transmitted by hand to the moving state of the clip. This improves the ease of use of the operator's clip apple liar and prevents ligation errors at the same time.
