Definitions
- the present invention relates to an end tool of a surgical instrument and a surgical instrument having the same, and more particularly, to a surgical instrument mounted on a robot arm or manually operated for use in laparoscopic surgery or various various surgeries, two It relates to an end tool of a surgical instrument having an end tool that is rotatable in more than one direction and operates to intuitively coincide with the operation of a manipulation unit, and a surgical instrument having the same.
- Laparoscopic surgery which can reduce postoperative recovery time and complications through a small incision, has been actively used.
- Laparoscopic surgery is a method in which a number of small holes are drilled in a patient's abdomen and the inside of the abdominal cavity is observed through these holes, and is widely used in general surgery and the like.
- a suture device inserted into the body is used to suture the surgical site in the abdominal cavity.
- Surgical Stapler is a medical instrument frequently used for cutting and anastomosis of organs in abdominal and thoracic organ surgery.
- a stapler for surgery there are an open stapler used in an open chest or a laparotomy, and an endo stapler used in a thoracoscopy and laparoscopy.
- the surgical stapler can perform organ anastomosis at the same time as cutting the surgical site, it has the advantage of shortening the operation time and achieving accurate suturing of the surgical site.
- the surgical stapler is widely used in modern surgical operations due to its advantages of faster recovery and less scarring than when using a surgical suture for tissue cutting and suturing.
- a surgical stapler is widely used to cut cancer tissue and suture the cut site in cancer surgery.
- the present invention is a surgical instrument mounted on a robot arm or manually operated for use in laparoscopic surgery or various surgeries, an end tool that is rotatable in two or more directions and operates to intuitively match the operation of the manipulation unit.
- An object of the present invention is to provide a provided surgical instrument.
- Article 1; Article 2 formed to face the Article 1; Article 1 pulley coupled to the first set and formed to be rotatable about a first axis; Article 2 pulley coupled to the Article 2, formed to be rotatable about an axis substantially the same or parallel to the first axis, and formed to be spaced apart from the Article 1 pulley to a certain extent; and a staple driving assembly including one or more staple pulleys at least partially formed between the Article 1 pulley and the Article 2 pulley; and an end tool including; an end tool connected to the staple driving assembly to rotate the staple pulley a reciprocating assembly that moves linearly by the lower surface; and a working member that comes into contact with the reciprocating assembly and moves in the one direction by the reciprocating assembly when the reciprocating assembly moves in one direction.

- the reciprocating assembly 550 moves in the direction of the distal portion 1001f when the jaw 1003 is opened. That is, the reciprocating assembly 550 moves forward.
- the reciprocating member moves backward when the jaw is opened because the amount of reciprocation of the reciprocating assembly due to the rotation of the staple pulley is greater than the amount of advance of the reciprocating assembly due to the rotation of the jaw pulley.
- the advance amount of the reciprocating assembly due to rotation of the jaw pulley is greater than the amount of advance of the reciprocating assembly due to rotation of the staple pulley, so that the reciprocating member advances when the jaw is opened.

- the protrusion member 1161b may be formed to be eccentric with respect to the staple pulley 1161 to a certain degree. Accordingly, when the staple pulley 1161 rotates, the first link 1172 may be moved by pushing the slot 1172d while the protruding member 1161b is in contact with the slot 1172d. That is, when the staple pulley 1161 rotates, the protruding member 1161b moves while in contact with the slot 1172d within the slot 1172d, whereby the first link 1172 is the guide of the first set 1101. It can move linearly along the groove 1101b.
- the staple pulley 1161 and the staple link assembly 1170 are coupled in the form of a cam/slot. That is, the protruding member 1161b formed in the staple pulley 1161 is coupled to the slot-shaped slot 1172d formed in the staple link assembly 1170 . Accordingly, when the staple pulley 1161 rotates in the arrow R direction, the displacement of the protruding member 1161b of the staple pulley 1161 in the X-axis direction becomes D1. And, the displacement in the X-axis direction of the staple link assembly 1170 becomes D2.
- the staple pulley 161 and the staple link assembly 170 are axially coupled, and thus the X-axis direction of the protruding member 1161b of the staple pulley 1161 .
- the displacement to the pole becomes much longer than in the fourth embodiment.
- the staple pulley 1161 and the staple link assembly 1170 are coupled in a cam/slot form, and the X-axis of the staple link assembly 1170 by the rotation of the staple pulley 1161 Since the displacement in the direction is relatively reduced compared to other embodiments, the force received by the staple link assembly 1170 in the X-axis direction is relatively increased compared to other embodiments.
- the force for advancing the staple link assembly 1170 and the reciprocating assembly 550 connected thereto is amplified, so that the stapling operation is more robustly performed. .
- the reciprocating assembly 550 and the working member 540 in an inactive state in which the reciprocating assembly 550 and the working member 540 are not engaged and separated, and an activated state in which the reciprocating assembly 550 and the working member 540 are coupled to each other. It is characterized in that the state exists. And, the inactive state can be maintained in the jaw open state, and it is possible to switch from the inactive state to the active state in the jaw closed state. In addition, after the activation state, the reciprocating assembly moves forward and backward according to the alternating rotational motion of the staple pulley, and the working member moves forward while repeating forward and backward movements.
- B1 in FIG. 147 which is the distance between the rotation shaft 1141 and the staple link assembly 1170 (the second protrusion 1172b among them) in a state in which the jaw 1103 is closed, is the jaw 1103 is open.
- the distance between the rotating shaft 1141 and the staple link assembly 1170 (the second protrusion 1172b among them) in the state is greater than B2 in FIG. 148 . (i.e. B1 > B2)
