The present invention relates to a cannula for surgical procedures. Specifically, the present invention relates to a cannula for a procedure used for liposuction.

Liposuction is the removal of fat cells from the fat layer accumulated in the human body, and is a cosmetic surgery field that has recently been in the spotlight with a diet craze. In general, fat cells stop increasing in size at puberty and only increase in size. In general, diet or exercise diet is to reduce the size of the fat cells, it is difficult to suppress the fat layer thickening to increase the size of the fat cells in the future. Liposuction, on the other hand, reduces the number of fat cells in specific areas of the body and is mainly used for local obesity.

Conventional liposuction involves suctioning adipose tissue into the suction port formed in the suction tube by vacuum and cutting the fat layer sucked into the sharp edge that forms the boundary of the suction port. In this case, blood vessel, muscle layer, and skin layer may be damaged. have.

Figure 1a is a view showing a conventional liposuction cannula, Figure 1b is a view showing an exploded view of a conventional cannula. 1A and 1B, the cannula 10 of the related art has a suction pipe 12 having a hollow pipe shape, a hub 14 and a hub to which one end of the suction pipe 12 is fixed. The handle portion 18 is coupled to the suction pipe 12, the hub 14, and the handle portion 18 are all formed of a metal material.

The suction pipe 12 is formed in a hollow pipe shape, and the front end is closed and the rear end is opened to allow the flow of fat. Meanwhile, a plurality of suction ports 12a are formed at the front end portion of the cannula 10 shown.

The suction port 12a is an inlet for fat intake, and preferably, three suction ports 12a are formed on the left and right sides and the top or the bottom. Therefore, it is comprised so that fat may be inhaled simultaneously from three directions.

The suction pipe 12 moves between the fat layers according to the user's operation, and the fat layer adjacent to the suction port 12a is crushed by the sharp edge formed at the boundary of the suction port 12a and sucked into the suction port, so that the internal passage 12b of the suction pipe is carried out. Along to hub 14.

On the other hand, the hub 14 is a portion in which the rear end of the suction pipe 12 is fixed by welding or the like, and is formed to have a relatively larger outer diameter than the suction pipe 12. On the other hand, the rear end of the hub 14 is provided with a male screw portion 14 ', and the male screw portion 14-1 is combined with a female screw portion (not shown) formed at one end (tip) of the handle portion 18 to form the hub ( 14 and the handle portion 18 are fastened.

However, when using the cannula according to the prior art as described above has the following problems.

First, the sharp edge portion of the conventional inlet 12a of the cannula damages the blood vessel, muscle layer or skin layer of the patient, thus causing excessive bleeding or muscle and skin damage.

In addition, in this case, since the conventional cannula is made of a metal material, the doctor performing the procedure cannot check in real time whether the fat layer is decomposed or the muscle layer is damaged and there is bleeding, and blood or the like is connected to the cannula. Only after passing through the inhalation device (not shown) can the current bleeding be confirmed.

In addition, the conventional cannula is heavy because it is formed of a metal material, and thus, it is difficult for an operator (doctor, etc.) to use for a long time, and because it is formed of a metal material, it is difficult to couple between the suction pipe 12 and the hub 14, and thus, manufacturing cost There is a problem that is expensive.

In addition, since the fat collected by the above-described cannula is broken down into very small tissues by the edge of the suction port 12a, in the case of magnetic fat transplantation, the fat engraftment rate is low and the fat transplantation efficiency is lowered.

The present invention has been made to solve the problems of the conventional cannula described above, the technical problem to be achieved by the present invention is to minimize the damage to blood vessels, muscle layers and skin layers other than the fat layer, the operator in the case of bleeding occurs It is to provide a liposuction cannula that can check and take action in real time.

In addition, another technical problem to be achieved by the present invention is to provide a liposuction cannula that can be easily used by the operator for a long time by significantly reducing the weight of the cannula, the structure can be simplified to lower the manufacturing cost.

Liposuction cannula of the present invention for achieving the above technical problem, both ends are open, the suction tube made of a transparent plastic material for guiding the fat set introduced into the interior through one end inserted into the human body, and the suction tube It surrounds the outer surface of one end of the, and connects the suction tube and the predetermined inhaler, and includes a handle portion for guiding the set of fat discharged from the suction tube to the inhaler.

In addition, one end inserted into the human body is preferably formed to be inclined.

In addition, one end of the corner inserted into the human body may be rounded tapered.

In addition, the handle portion, the first coupling port formed on one end of the handle portion, the second coupling portion formed on the handle portion to insert and engage the inhaler, so as to couple the outer surface of one end of the suction pipe to engage the one end of the suction pipe, and It may include a guide portion formed through the handle portion to guide the fat set discharged from the suction pipe to the inhaler.

In addition, the inner surface of the first coupler and the outer surface of the suction pipe may be coupled by a predetermined adhesive.

In addition, the second coupler may be coupled to the inhaler by interference fit, or when a screw thread is formed inside the second coupler, the second coupler may be coupled to the inhaler by a screw thread.

In addition, irregularities may be formed on the surface of the handle part.

Hereinafter, with reference to the accompanying drawings will be described preferred embodiments of the present invention.

First, the suction pipe 22 is formed of a plastic of transparent material, and unlike one end of the conventional liposuction cannula, both ends of the suction pipe 22 of the present invention are formed to be opened, and the A moving passage 22b through which the fat set can move is formed inside. The suction pipe 22 is formed to have a length of about 30cm to 50cm in length depending on the intended use, an outer diameter of about 6mm to 8mm, and an inner diameter of 4mm to 6mm.

In addition, the suction port 22a which is one end of the suction pipe 22 inserted into the human body of the patient is preferably formed to be inclined to have a predetermined angle with respect to the central axis of the suction pipe 22. The inclination angle is preferably formed to have an inclination of about 30 degrees to about 60 degrees with respect to the central axis, and most preferably, to have an inclination of about 45 degrees with respect to the central axis. Since the suction port 22a is formed to be inclined, the suction pipe 22 is inserted into the fat layer of the human body, and thus is easily moved along the fat layer.

The boundary region of the suction port 22a can be formed not only sharply, but also tapered and formed at an obtuse angle.

On the other hand, the handle portion 26 is formed of a plastic material so that the user can easily operate by reducing the weight, unlike the prior art metal cannula, the first coupler (26-1), the second coupler (26) -3), guide portion 26-2, and gripping surface.

First, the handle portion 26 is formed with a first coupler 26-1 for coupling the suction pipe 22 so that the other end corresponding to the inclined end of the suction pipe 22 is introduced into and coupled to the handle portion 26. The inner diameter of the first coupling hole 26-1 is slightly larger than the outer diameter of the suction pipe 22, and the inner surface of the first coupling hole 26-1 of the handle portion 26 is connected to the outer surface of the suction pipe 22 and the adhesive.

A suction hose or the like is connected to the handle portion 26. At this time, the syringe or suction hose is coupled to the second coupling hole 26-3 by interference fit. In this case, however, a screw thread may be formed on the inner surface of the second coupler 26-3, so that the screw thread may be screwed with the syringe or suction connector formed with the screw thread.

In addition, a guide portion 26-2 connecting the first coupler 26-1 and the second coupler 26-3 is formed inside the handle portion 26, so that the first coupler 26-1 is provided. The fat set introduced from the suction pipe 22 coupled to the) passes through the guide portion 26-2 and flows out to the syringe or suction connection tube connected to the second coupling hole 26-3. At this time, the inner diameter of the guide portion 26-2 is preferably the same as the inner diameter of the suction pipe 22, and therefore, preferably has an inner diameter of about 4 mm to 6 mm.

On the other hand, the gripping surface (26-4) of the handle portion 26 is formed with irregularities at regular intervals to prevent the user from slipping when performing the procedure. 2 and 3 show an example of irregularities formed in the gripping surface 26-4. 2 and 3, the gripping surface 26-4 is formed at regular intervals of plastic surfaces having a constant thickness in a vertical direction with respect to the central axis of the handle part 26. In addition, the gripping surface 26-4 may form irregularities by forming protrusions on a smooth surface at regular intervals.

Referring to FIG. 4, the operator inserts an intake port 22a, which is an inclined cross section of the suction tube 22, into the fat layer of the human body, and injects the syringe 40 into the cannula handle portion 26 to suck the patient's fat. 2 After inserting the syringe into the coupling hole (26-3), the syringe 40 is pulled to apply pressure to the inside of the syringe (40).

Then, the operator grasps the gripping surface 26-4 and manipulates the cannula to move the suction tube 22 along the fat layer of the patient, and the fat layer is crushed by the interface of the suction port 22a, and the suction tube passes through the suction port 22a. (22) flows into the interior. The fat set introduced into the suction pipe 22 is moved in the direction of the first coupler 26-1 along the inner passage 22b of the suction pipe 22 by the pressure formed at the syringe side, It passes through the guide portion 26-2 and flows into the syringe 40 inserted into the second coupler 26-3. The fat set collected in the syringe 40 is larger in size than the fat set collected by the conventional cannula as described above, and thus can be effectively used for fat insertion.

On the other hand, the operator can determine the material moving through the transparent suction tube 22, and can determine in real time whether the current fat layer is crushed or the muscle layer is damaged and bleeding to significantly reduce medical accidents caused by excessive bleeding Can be.
