The ultrasonic cutting machine assembly 1 according to the present invention includes all devices that can be used for laparoscopic surgery, for example, by fixing the internal organs of the human body, such as the stomach, duodenum, or the like, with ultrasound. In addition, in some cases, it is not limited to laparoscopic surgery, and may be applied to various surgical or medical procedures.

The ultrasonic cutting machine 100 operates the clip tip 130, a handle unit 110 in which manipulation components including a substrate are accommodated, and a rotation unit 140 coupled to the front of the handle unit 11, and rotation It is coupled to the unit 140 and is provided on the front end of the receiving tube 120 and the receiving tube 120 in which the ultrasonic transducer (not shown) is accommodated, and is connected to the ultrasonic transducer (not shown) to generate heat to form part of the body It includes a clip tip 130 to cut or grip.

The handle unit 110 is provided at the lower portion of the handle body 111, the handle body 111, and is provided with a handle 113 that is gripped by a user by hand, and is provided to be movable at the tip of the handle 113 so that the user can It includes a tip operation handle 115 for manipulating the clip tip 130 by pressing with.

The handle body 111 is formed to have a predetermined volume, and the inside is formed to have a hollow structure so that the air introduced through the suction pipe 210 can be moved to the discharge pipe 230 at the rear end. Although not shown in the drawing, the handle body 111 has a structure for manipulating the clip tip 130 including the substrate and a configuration for rotating the rotating unit 140.

The configuration of the ultrasonic cutting machine 100 may be applied to various structures known in the art.

The suction module 200 is coupled to the ultrasonic cutting machine 100 to quickly remove the smoke generated during surgery by removing it to the outside. The suction module 200 is a suction pipe 210 coupled to surround the outside of the receiving pipe 120 and a suction control unit 220 coupled to the handle unit 110 to adjust the sound pressure to control whether or not the smoke is sucked and the suction degree ), The discharge pipe 230 for discharging the smoke (A) moved along the suction pipe 210 by the negative pressure to the outside, and a filter member 240 provided at the tip of the discharge pipe 230 to remove the toxicity contained in the smoke ).

The suction pipe 210 is coupled to receive the entire receiving pipe 120 except for the clip tip 130. As shown in Figure 3, the receiving tube 120 is inserted into the suction tube 210. The rear end of the suction pipe 210 is accommodated inside the handle unit 110 in a range that does not interfere with the operation of the rotating unit 140 and the handle unit 110.

The inner diameter of the suction pipe 210 is formed to be larger than the outer diameter of the receiving pipe 120 to form a free space between the suction pipe 210 and the receiving pipe 120. The sucked smoke is moved to the handle unit 110 side through the free space between the suction pipe 210 and the receiving pipe 120.

A plurality of suction holes 211 for sucking smoke is formed through the tip of the suction pipe 210. For laparoscopic surgery, a part of the body is incised, a trocar is installed, and carbon dioxide is injected into the abdominal cavity to form a space in the abdominal cavity.

At this time, since carbon dioxide is injected, the inside of the human body is maintained at a high positive pressure. In this state, when connected to the outside air by the suction pipe 210, the outside is in a relatively negative pressure state. When a negative pressure is applied through the suction hole 211, smoke inside the abdominal cavity flows into the suction hole 211 by the negative pressure.

The area where the suction hole 211 is formed is preferably formed in a range of 3 to 6 cm in length from the tip of the suction tube 210. If the forming area of the suction hole 211 is narrower than 3 cm, the suction area is narrow, so that the smoke cannot be quickly absorbed. If the suction hole 211 is larger than 6 cm, the applied pressure is inversely proportional to the area, so that the smoke is properly discharged. It cannot be inhaled.

The suction operation unit 220 adjusts the sound pressure applied to the suction tube 210. As shown in (a) and (b) of FIG. 4, the suction operation unit 220 has a discharge pipe connection gate 221 connected to the discharge pipe 230 through a filter member 240, and a tip end of the discharge pipe connection gate 221. It is provided in the gate opening and closing ball 223 to open and close the discharge pipe connection gate 221, the gate opening and closing ball 223 is operated by the user so that the linear movement of the gate opening and closing 225 and the gate opening and closing 225 It includes a connection link 227 for transmitting the movement to the gate opening and closing ball 223.

The discharge pipe connecting gate 221 is formed in a circular pipe shape. The filter member 240 and the discharge pipe 230 are sequentially connected to the rear end of the discharge pipe connection gate 221. The discharge pipe connecting gate 221 controls the opening degree by the gate opening and closing ball 223 and forms a passage through which smoke is discharged by applying negative pressure.

The gate opening / closing ball 223 opens and closes the discharge pipe connecting gate 221 in conjunction with the operation of the gate opening / closing opening 225. The gate opening and closing ball 223 is formed in a hemispherical shape toward the discharge pipe connecting gate 221. The diameter of the gate opening and closing ball 223 is formed to correspond to the inner diameter of the discharge pipe connecting gate 221. Accordingly, when the gate opening / closing ball 223 is accommodated in the discharge pipe connecting gate 221 as shown in FIG. 4 (b), neither negative pressure is applied and smoke is not discharged to the outside.

On the other hand, as shown in Figure 4 (a), when the gate opening and closing ball 223 is spaced apart from the discharge pipe connecting gate 221, negative pressure is applied through the discharge pipe 230, and smoke is moved to the discharge pipe 230.

The gate opening and closing ball 223 is fixed to the coupling shaft 224 by a connecting shaft 223a. The coupling shaft 224 is coupled to the rotational member 225b of the gate opening and closing 225 to move back and forth from the distal end of the discharge pipe connection gate 221 in conjunction with the operation of the rotational member 225b.

The gate opening and closing cover 225 is formed by combining a fixed member 225a and a rotating member 225b bent in the shape of an "S" with a circular elastic member 225c interposed therebetween. The fixing member 225a is fixedly coupled to the rear end of the handle body 111, and the pivoting member 225b is elastically movable with respect to the fixing member 225a.

In the state that the user does not grip by hand, as shown in Fig. 4 (a), the gap (1) at the top of the fixing member (225a) and the rotating member (225b) is formed narrow, the gap (ℓ2) at the bottom It is formed broadly.

In this state, when the user grasps the lower ends of the fixing member 225a and the rotating member 225b by hand and compresses them, the gap at the top (ℓ3) widens (ℓ1 <ℓ3), and the gap at the bottom centers around the elastic member (225c). (ℓ4) narrows (ℓ3> ℓ4).

When the gap at the upper end is wide, the gate opening and closing ball 223 provided on the connecting shaft 223a connected to the upper coupling shaft 224 moves in a straight line and blocks the discharge pipe connecting gate 221.

Here, a connection link 227 is provided between the rotating member 225b and the discharge pipe connecting gate 221 to transfer the movement of the rotating member 225b. One end of the connection link 227 is fixed to the discharge pipe connection gate 221, and the other end is provided to be movable on the moving shaft 226.

The moving shaft 226 is formed to protrude on the upper end of the rotating member 225b, and is fitted into the moving slit 227a formed in the connecting link 227. When the rotation member 225b is moved according to the pressure of the user, the moving shaft 226 linearly moves inside the moving slit 227a and guides the movement of the connecting shaft 223a. The moving slit 227a also serves to limit the moving distance of the rotating member 225b.

By this operation, the gate opening / closing ball 223 may completely open, partially open, or completely close the discharge pipe connecting gate 221 according to the pressure of the user holding the gate opening 225. Therefore, the user can control the degree of gripping with a desired hand to control the amount of smoke discharged.

The discharge pipe 230 is connected to the filter member 240 at one end and opened at the other end. Accordingly, the outside air is exposed to the inside of the human body in a positive pressure state to apply negative pressure. Smoke is sucked through the suction pipe 210 by the application of negative pressure.

The filter member 240 is provided at the tip of the discharge pipe 230 to remove harmful components contained in smoke flowing into the discharge pipe connection gate 221. The filter member 240 may be used in various known forms.

The process of using the ultrasonic cutting machine assembly 1 according to the present invention having such a configuration will be described with reference to FIGS. 2 to 5.

For laparoscopic surgery, a trocar is installed through a 1 cm incision on the patient's belly button, and carbon dioxide is injected into the abdominal cavity to form a surgical space in the abdominal cavity. A special camera is inserted to check for lesions in the abdominal cavity through a video monitor.

The trocar is installed according to the type of surgery, and the ultrasonic cutting machine assembly 1 is inserted into the human body. The operator manipulates the clip tip 130 using the handle and the tip manipulation handle 115 to grip or cut a part of the body.

In this process, smoke is generated by heat generated by ultrasonic waves. The operator operates the gate opening 225 as shown in FIG. 4 (a) so that the discharge pipe connecting gate 221 is opened. As a result, a relative pressure difference is generated between the external air and the intraperitoneal pressure, and a negative pressure is applied.

When negative pressure is applied, smoke A is sucked through the suction hole 211 of the suction pipe 210 as shown in enlarged view in FIG. 5. The inhaled smoke A is moved to the space between the suction pipe 210 and the receiving pipe 120, and after being discharged outside the suction pipe 210, it is moved along the inside of the handle body 111 to the discharge pipe connecting gate 221. Inflow.

Then, while passing through the filter member 240, the harmful substances inside the smoke A are removed and discharged to the outside through the discharge pipe 230.

In this process, since the smoke generated between the clip tip 130 and the body part is quickly removed, there is no problem of covering the operator's field of view or covering the camera. Therefore, the surgery can proceed quickly.

As described above, the ultrasonic cutting assembly according to the present invention is formed by combining a suction module that sucks smoke into an ultrasonic cutting machine. Accordingly, when laparoscopic surgery is applied, a negative pressure is applied to quickly remove smoke generated when the ultrasonic cutting machine cuts part of the body.

Since it is possible to remove smoke quickly, it is possible to solve the problem that the operation was delayed by smoke during conventional laparoscopic surgery.

In addition, since the harmful substances contained in the smoke are removed using the filter member, it is possible to prevent the emitted smoke from having a harmful effect on the human body.

The embodiment of the ultrasonic cutting machine assembly of the present invention described above is merely exemplary, and those skilled in the art to which the present invention belongs can know that various modifications and other equivalent embodiments are possible. Will be able to. Therefore, it will be understood that the present invention is not limited to the forms mentioned in the above detailed description.
