Description

Trocar easily suturing {

The present invention relates to a trocar for use in laparoscopic surgery. More particularly, the present invention relates to a trocar used for laparoscopic surgery. More particularly, the present invention relates to a trocar used for laparoscopic surgery, So that the sewing work can be carried out easily.

Laparoscopic surgery was performed by purging 4 ~ 6 pores of 0.5 ~ 1.2cm in the abdomen, and then placing a trocar of 0.5 ~ 1.2cm in diameter and 15 ~ 16cm in length into the abdomen. It is a surgical method to insert a light source and a camera into a hole, insert various kinds of surgical instruments into other holes, and cut and organize an organ while looking at a monitor outside.

Laparoscopic surgery is performed by inserting a large number of trocar into the abdomen of a patient and injecting a gas such as carbon dioxide gas into the abdominal cavity through one trocar to secure relief of the abdominal cavity to secure an operative space, The endoscope and the surgical instrument inserted through the car are used to perform the operation while observing the surgical site.

When the procedure is completed, the suture is inserted into the inside of the abdomen of the surgical site using the needle, and the surgical site is sewn using the suture apparatus.

As shown in Fig. 1, the trocar includes a bracing tube 1 that is inserted into the abdominal cavity of a patient, and a main body 2 provided at the upper portion of the bracing tube and guiding the insertion of the surgical instrument.

At this time, the penetration is small in diameter in order to minimize the scarring of the patient, and the main body has two valves for injecting and discharging gas at the upper part and a plurality of heads for injecting the surgical instrument, And a filter member for filtering is built in, which is large in diameter.

Therefore, when the needle 3 is pierced by the abdominal skin of the surgical site (i.e., around the perforation), it is inconvenient for the main body 2 to interfere with the insertion of the needle 3 into the surgical site next to the perforated tube 1.

Referring to FIG. 1, when the needle 3 is inserted vertically into the abdominal region 4 by the interference of the main body 2, the needle 3 is inserted at a position distant from the percutaneous tube 1, The needle 3 can be inserted at a position nearer to the breech tube 1 when the needle 3 is tilted, but it is also possible to insert the needle 3 at a position close to the breech tube 1 There is a limit and the needle 3, that is, the suture, can penetrate the abdominal wall 4 at an angle, the suture can escape from the surgical site, the suture of the suture is poor, and the knot may be defective.

During laparoscopic surgery, the practitioner should pay close attention to the procedure, such as incising the tissue within the abdominal cavity. Such an operation usually requires careful technique, and mistakes in the procedure can cause a medical accident that threatens the life of the patient.

Suturing of the surgical site after completing the procedure is not a difficult task and rarely causes medical accidents caused by suture.

Thus, when the procedure is completed, the practitioner wants to be able to quickly suture the surgical site as the concentration is lowered and fatigue is sharply urged.

However, in the prior art, the body of the bulky trocar interferes with the movement of the needle for sealing, making it difficult for the operator to suture with time and attention.

For reference, in the prior art relating to a device for closing and closing a surgical site, that is, a laparoscopic boat site in which a catheter of a trocar is inserted, after completion of the procedure of laparoscopic surgery, Japanese Patent Application No. 10-1594082 entitled "Laparoscopic Port Site Closure Device" .

Although the above-mentioned patent No. 10-1594082 entitled "Laparoscopic Port Site Closure Device" is effective for binding (knot) of a suture, it is a complicated and expensive product, This is a product that is not preferred by practitioners because it takes a lot of time.

In order to solve the problem of the prior art in which the body of the trocar interferes with movement of the needle when the needle for suturing is inserted into the skin of the surgical site and thus the suturing operation is difficult and the needle can not be pushed into the correct position, The main body and the penetrating tube are detachably coupled to each other to separate the main body from the main body during the suturing operation so as to prevent the main body from interfering with the main body so that the operator can easily and quickly perform suturing. And a guide tube for guiding the insertion of the needle is provided at an edge of the cap so that the operator can insert the needle accurately into the skin at a desired position and angle.

In order to achieve the above-mentioned object, the trocar according to the present invention,

A catheter inserted into the abdominal cavity;

A body detachably coupled to the upper portion of the penetrating tube and guiding the insertion of a surgical instrument;

And a cap detachably coupled to the upper portion of the penetrating tube and having a guide member for guiding the insertion position of the needle for sealing into the abdominal cavity.

And the guide member is provided at an edge of the cap and is a guide tube passing through the needle for sealing,

And a clearance adjusting member for adjusting clearance between the cap and the guide member,

And the clearance adjusting member can adjust the direction of the guide member.

The trocars according to the present invention are convenient for the suturing operation. When the suture is closed, the main body is separated from the sutured tube and the suture is not obstructed by the main body. Thus, the concentration is decreased and the tiredness suddenly comes down. It is possible to suture the surgical site precisely.

 Further, the guide tube provided at the edge of the cap guides the position and the angle at which the needle for insertion is inserted, so that the operator can precisely insert the needle into a desired position, thereby improving the accuracy of the sealing operation.

After the procedure, the contaminated tubing can be separated from the main body and discarded, and a new tubing can be used in combination with the main body, thereby preventing waste of resources and reducing the cost of the patient.

When the thickness of the abdominal wall varies according to the patient, a tube having a length suitable for the abdominal wall can be used in combination with the body, which is excellent in compatibility.

In addition, if the volume of the incised tissue is large during laparoscopic surgery and the tissue is difficult to pull through the body of the laparoscope, the body can be removed from the catheter and the incised tissue can be extracted.

As shown in the drawing, the trocar according to the present invention is convenient for the sewing operation. The trocar includes a tube 10, a main body 20, a cap 40, a guide member 50 and a clearance adjusting member 60.

The perforation 10 is inserted into the abdominal cavity through a small incision in the abdomen 4 of the patient.

The perforated tube 10 has a cylindrical structure in which a hollow is formed in the longitudinal direction so as to penetrate a surgical instrument.

An annular protrusion may be formed on the outer circumference of the penetrated tube 10 so as to exert a clamping force on the abdominal wall 4 of the patient so that the penetrated tube 10 is not easily separated from the abdomen 4 in an unintentional situation.

A hook or a hook protrusion may be formed on the upper portion of the tubing 10 so that the main body 20 or the cap 40 is detachably coupled to the main body 20 by a screw or a hook. The main body 20 and the cap 40, which are detachably coupled to the perforated tube 10, may be formed with screw threads or hook-shaped hooks or hook protrusions engaged with the hooks.

The main body 20 is detachably coupled to the upper portion of the tubing 10. A hook groove or a hook projection is formed at a lower center of the body 20 to be threaded or hooked to the body 10 or the body 20 by screwing.

The main body 20 is inserted into the abdominal cavity through the penetration tube 10 with a surgical instrument inserted therein.

The upper part of the main body 20 is provided with a gas valve 21 for injecting gas into the abdominal cavity of the patient and a head part 23 through which the surgical instrument is inserted. In general, the head portion is provided with several different lengths and diameters so that various types of surgical instruments can be inserted.

The cap 40 is detachably coupled to the upper portion of the tube 10 and the guide member 50 is provided in the cap 40 to penetrate the needle 30 for sealing, That is, to be inserted into the abdominal cavity.

The needle 30 is releasably connected to a suture at its end so that the suture can be inserted into the abdominal cavity of the patient or the suture in the abdominal cavity can be pulled out of the abdomen 4.

The guide member 50 can use a ring (not shown) connected to the edge of the cap 40. The guide member 50 has a thickness greater than a certain level at the edge of the cap 40, A hole (not shown) may be formed, and this through hole may be used as a guide member.

As shown in the drawing, a guide pipe of a pipe-like structure may be used as the guide member 50. When the guide tube 50 is used as the guide tube 50, the needle 30 passing through the guide tube goes straight in the direction of the guide tube without shaking, So that it is possible to prevent a situation in which the needle 30 is deflected in the process of sticking the needle 30 into the abdominal wall 4 and inserted into another position.

The clearance adjusting member 60 connects the cap 40 to the guide pipe 50 and adjusts the length of the guide pipe 50 to adjust the clearance between the cap 40 and the guide pipe 50.
