Description

Trocar {Trocar}

The present invention relates to a laparoscopic trocar (Trocar) that can be operated without opening during abdominal surgery, more specifically in a support tube of a trocar needle inserted into the trocar sleeve to puncture the abdominal skin The slide rod is installed to protect the organs during abdominal puncture, while the inlet of the sleeve tube installed in the bushing head is doubled to insert the surgical instrument smaller than the diameter of the bushing installed in the abdomen. And it relates to a trocar designed to block the carbon dioxide gas inside the draw through the sleeve tube.

Existing trocar is fixed to install the permeable insertion sleeve installed in the head portion to match the bushing coupled to the bottom and then to maintain the airtight so that a separate flow piece corresponding to the end of the sleeve tube can be supported by the spring bullet As a result, when the needle is pushed into the sleeve tube inlet, the needle bar is inserted into the bushing while pushing the flow piece corresponding to the sleeve tube end so that the needle tip protrudes. The trocars as described above may injure the internal organs by the force while puncturing the abdominal wall of the patient. Therefore, the abdominal wall perforation should be carefully performed at all times, and the recovery may be delayed if the organ is injured by mistake. do.

In order to perform laparoscopic surgery, a large number of trocar needles are inserted into the abdominal wall of the patient. At this time, a single needle is used to insert a plurality of trocar needles into the abdominal wall. In order to secure an operation field in an abdominal surgery using an endoscope, Carbon dioxide gas is injected through the valve to maintain the ups and downs, and the flow piece corresponding to the end of the sleeve tube is closely contacted by spring springs interposed on one side of the shaft. Therefore, if the elastic force distribution does not occur uniformly on the fluidized surface, there is a disadvantage that carbon dioxide is leaked, and the carbon dioxide is not discharged to the head of the trocar after surgery, and thus a separate means is taken and discharged. There was a disadvantage that the carbon dioxide emission time is delayed. In particular, since the conventional trocar is an expensive product imported from all over the world, there was an unsanitary problem by reusing and disinfecting it, rather than using it once and discarding it.

The present invention is devised to solve the above problems, the penetrating needle is composed of a support tube, a handle, a slide rod, the tip having a needle, the bushing is installed in the upper head sleeve sleeve but the sleeve tube end and sleeve tube Magnets are installed on the inner surface of the trocar head corresponding to the inner wall, and the trocar is configured to have a double inlet for penetrating into the trocar head, and the present invention can perform laparoscopic surgery without open surgery during long-term surgery in the abdomen. To prevent the inflow of external air into the abdomen when drawing in and out of the surgical instrument in the trocar during surgery, to improve the adhesion between the inner wall of the bushing and the sleeve tube of the unused bushing, and the penetration is introduced into the abdomen The slide rod protrudes at a moment to protect the organs. Even during surgical instruments belonging to the category in which it is used are designed to maintain confidentiality.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In the laparoscopic trocar that can be operated without opening in the abdominal surgery by inserting the penetrating needle with the safety rod in the bushing having a sleeve in the head,

A magnet tube 14 and 14 ′ having a sleeve tube 12 installed in the head portion 11, but wrapped around the end of the sleeve tube tube 12 and the inner wall to which the sleeve tube 12 corresponds, are wrapped with a silicon sheet 13. and;

A bushing 10 having an inlet 15 having an upper inlet 15a and a lower inlet 15b provided in a double manner so that a surgical instrument having a size equal to or smaller than the diameter of the bushing 10 is introduced into the sleeve tube 12. ; And

A handle portion 24 provided with a slide portion 25 having a space portion 27 at a central portion, a pressing piece 26 at one side, and a ball projecting protrusion 25 'fitted at a spring 23' on the other side;

A support tube 21 having a tip 21 'at the bottom of the handle 24 is fixed, and a penetration rod made of a slide rod 22 which is pulled up and down by a spring of the spring 23 inside the support tube 21 ( 20);

The configuration of the trocar (15) made by sandwiching the trocar (20) in the trocar (10),

A through hole 17 is formed in the center of the upper plate 16 of the sleeve tube 12, the inlet 15 of the bushing 10, and a guide tube 19 having a silicon packing 18 having a small through hole 17a is coupled to the bottom thereof. An upper inlet 15a;

The lower portion of the upper inlet 15a having a funnel model guide tube 19 'having a large through hole 17b with a silicon packing 18' so that the penetration needle 20 can be inserted into the sleeve tube 12 is fixed. Inlet 15b;

The upper inlet 15a and the lower inlet 15b are configured to be opened and closed by the hinge part 40 formed on one side of the upper plate 16.

Reference numeral 41 is a carbon dioxide gas control valve, 42 is the abdominal wall, 43 is the patient's organs.

The present invention configured as described above handles the upper end of the needle 20 against the skin of the patient's abdominal wall 42 at the end of the trocar 30 at the end of the trocar 30 combined with the trocar 10 and the needle 20 at the time of surgery. (24) When the pressing piece 26 formed on one side is pressed, the slide plate 25 is pushed, and the bullet protrusion 25 'compresses the spring 23', and the through hole 17 formed at the center of the slide plate 25 is It coincides with the slide rod 22 provided in the penetration needle 20 and the support pipe 21.

After pressing the pressing piece 26 of the handle 24 of the needle 20 as described above, the needle 21 'and the slide rod 22 of the end of the trocar 30 end correspond to the patient abdominal wall 42. When the trocar 30 is pressed in the state, the slide rod 22 is caught by the abdominal wall, and the tip 21 'punctures the abdominal wall.

At this time, in the process where the tip 21 'of the piercing needle 20 punctures the abdominal wall, the trocar needle 30 descends while the slide rod 22 is caught on the abdominal wall, and the bushing 10 and the piercing needle 20 are lowered to the inside of the abdominal wall. The slide rod 22 is drawn into the through hole 17 'of the slide plate 25 while compressing the spring 23 interposed therebetween.

Since the slide rod 22 is not caught on the distal end after the penetrating tip is introduced into the abdomen, the rod 22 is protruded back into the tip 21 'by the spring 23 on the upper side of the slide rod 22, thereby causing damage to organs in the abdomen. Prevent it from happening.

Thus, after the trocar 30 is installed in the abdomen of the patient, grabbing the handle 24 of the trocar 20 and pulling it out, the trocar is installed in the abdomen 42 and the trocar 20 is detached from the trocar. (10) The sleeve tube 12 is mounted on the head portion 11, and the magnet 14 'attached to the inner wall corresponding to the end of the sleeve tube 12 and the end of the sleeve tube 12 is pulled together to be attached to the sleeve tube 12. 3, the distal end is in contact with the inner wall of the head 11 and is in a closed state.

According to the present invention, after the bushing 10 is installed on the abdomen of the patient, surgery is performed, and before injecting carbon dioxide gas through the control valve 41 formed on one side of the head 11, the abdomen of the patient is expanded. The endoscope secures a visual field during surgery and secures a space for the surgical instrument to move.

At this time, the trocar 30 necessary for the operation is already installed before injecting the carbon dioxide into the abdomen of the patient, and in the state in which the carbon dioxide is injected, the head portion 11 and the sleeve tube 12 of the bushing 10 are inserted. Since the connection portion and the space portion of the state becomes closed with a thin and soft silicon sheet 13, the phenomenon that the outside air enters into the abdomen or the carbon dioxide gas from the outside does not occur.

In addition, the present invention, when inserting a surgical instrument corresponding to the diameter of the bushing 10 installed during surgery through the lower inlet 15b in the state of lifting the upper inlet 15a of the inlet 15 of the sleeve tube 12 Inserting the surgical instruments is in close contact with the outer surface of the surgical instrument inserted into the inner circumferential surface of the large through hole 17b of the silicone packing 18 'installed in the guide tube 19' of the funnel model to maintain confidentiality.

When a small surgical instrument is inserted into the lower inlet 15b, the silicon packing 18 'is smaller than the diameter of the large through hole 17b of the silicon packing 18' which forms the lower inlet 15b. The outer surface of the surgical instrument may not be in close contact with the inserted surgical instrument, and the carbon dioxide gas may leak out.

Therefore, the guide tube 19 having the silicon packing 18 of the small through hole 17a by closing the upper inlet 15a and the top plate 16 located above the funnel model guide tube 12 'connected to the sleeve tube 12 is provided. Since the bottom part is seated on the upper portion while pressing the silicon packing 18 'having the large through hole 17b, a small surgical instrument is inserted through the upper inlet 15a, so that the small through hole 17a and the silicon of the silicon packing 18 are inserted. It can be inserted into the abdomen via the large through hole 17b of the packing 18 '.

When the surgical instrument having a small thickness is inserted into the upper inlet 15a, the silicon packing 18 having the small through hole 17a is in close contact with the outer surface of the surgical instrument.

The present invention is to form an inlet 15 of the sleeve tube 12 having an inlet double, so that any one can be used if the thickness can be introduced into the trocar installed with the surgical instrument during the operation.

In addition, the present invention is provided with a ring-shaped magnet 14 so as to be inserted into the end portion of the sleeve tube 12 installed in the head portion 11 with a silicone sheet, and the head portion 11 correspondingly contacted with the end portion of the sleeve tube 12. By attaching a circular or square magnet 14 'to the inner wall, a silicon sheet is attached to the surface to maintain airtightness when self-locking with each other.

When the magnet 14 is attached to the sleeve tube 12 and the surface of the magnet 14 'is attached to the inner wall of the head portion 14' of the magnet, the N pole is positioned. When not installed so as to correspond to each other, the sleeve tube 12 is to be locked to the inner wall of the head portion 11 is closed.

According to the present invention, the sleeve tube 12 is automatically closed during surgery, so that the sleeve tube 12 is in close contact with the inner wall of the head portion 11 even though the bushing is not used for a while. The silicone sheet and the silicone sheet surrounding the (14 ') improve adhesion and maintain perfect airtightness to prevent contact with external air during the procedure and to allow for rapid recovery of the patient after surgery.

As described above, the present invention is performed by installing a trocar by drilling a small hole in the abdominal wall without cutting the various organs such as the gall, stomach, and uterus of the patient during surgery. The patient's recovery is not only quick because it does not come into contact with the air, and when the gas is removed after the operation, the head part of the trocar is moved slightly so that the vibrator coincides with the trocar so that the carbon dioxide filled in the abdomen is discharged in a short time. This can be done quickly, and in particular, it replaces the expensive product that is imported in full quantity and supplies it at a low price, and it prevents the side effects caused by the residual amount of unwashed blood by washing and disinfecting and reusing it to reduce the product purchase price burden. At the same time, reduce the cost of treatment The long trocar was able to be disposed of and had the effect of hygienic surgery.
