Surgical Indicator Clips and Clip Devices

The present invention relates to a surgical marker clip, and more particularly, to a surgical marker clip and a clip device having a marking function for displaying the location so as to find the exact position of the biological tissue incision site during surgery.

Conventionally, a surgical method generally used in surgical procedures for treatment of colorectal cancer, gastric cancer, etc. is performed by endoscopically injecting the body into the body, and visually confirming the treatment site, such as a cancer occurrence site, and then opening the body or performing laparoscopic surgery. The incision is removed by incision.

However, in the conventional method, since the viewing angle and range obtained through the endoscope and the viewing angle and range obtained through the laparoscopic or laparoscope are completely different, it is difficult to accurately find the target position to be incision outside the body. Therefore, there is a problem in that the accuracy and range of the incision inevitably vary depending on the operator's sense and skill.

On the other hand, as a way to solve this problem, the Korean Patent Application Publication No. 2005-0110013 "clip and clip of biological tissue" developed for the purpose of hemostasis during endoscopy and "CLIP DEVICE FOR ENDOSCOPE AND CLIP" of US Patent US07357805 FOR ENDOSCOPE FOR USE THEREIN ", etc., a living body clip is disclosed.

Here, the radioactive material 120a is a radioisotope that emits gamma rays so as to determine the correct position of the surgical indicator clip 100 in the living tissue using a gamma detector (not shown). The radioactive material 120a may use a short-lived medical radioisotope such as Tc-99m, I-123, etc. to ensure stability when leaking and to be convenient to use. Preferably, even when the radioactive substance 120a leaks and is absorbed into the body, the radiation substance 120a may be made of a form such as Tc-99m DTPA or the like which can be quickly discharged to the kidney.

Since the radiation material 120a generally contains a component harmful to a human body, the radiation storage case 121 may secure airtightness.

The radiation shield case 123 is coupled to the proximal side of the clip body 110. The radiation shield case 123 accommodates the radiation storage case 121 and is detachably coupled to the radiation storage case 121 for shielding and releasing the shielding of the radiation material 120a.

Can be. This has the function of shielding the radiation material 120a stored in the radiation storage case 121 when the first shielding portion 124 and the second shielding portion 125 of the radiation shielding case 123 are coupled to each other. When the second shield 125 is removed by the shield removing fastening unit 240 of the clip device 200, the radiation storage case 121 that is covered by the second shield 125 is exposed and the radiation storage case ( This is to allow the radiation material 120a of 121 to be emitted to the outside. That is, in order to allow the operator and the patient to be exposed to the outside only after gripping the clip to a desired area without the operator and the patient being continuously exposed to the radiation during the procedure using the surgical indicator clip 100.

The clip fastening part 140 for fastening the radiation display part 120 to the proximal end of the clip main body 110 may be coupled to the front end side of the first shielding part 124. Here, the clip fastening portion 140 extends forward from both sides of the front end of the fastening body 141 coupled with the first shielding portion 124 and the clip fastening protrusion 143 is formed inward at each extended end thereof.

In addition, the tightening ring 130 preferably has a length corresponding to the length of the stepped portion 113b of the clip body 110.

The material of the tightening ring 130 is not particularly limited, but may be made of the same material as the clip body 110 because it is used together with the clip body 110. For example, the fastening ring 130 is preferably made of a metal such as stainless steel and titanium alloy, or a plastic material such as ABS resin, hard vinyl chloride resin, polyamide and polyethylene.

Accordingly, the first shielding portion 124 and the second shielding portion 125 are separated and the shielding of the radiation storage case 121 is released, so that only the radiation storage case 121 is fastened to the clip main body 110 so that the radiation material 120a is released. ) Will be released to the outside.

Next, when the shielding of the radioactive material 120a is completed, the operation arm 230 is separated from the hook portion 113a and the clip device 200 is pulled out of the body. As shown in FIG. 17, the second shield 125 removes the state in which the second shield remover 242 is applied forward when the clip device 200 is finally pulled out of the body and the second shield is removed. When the rejection 242 is pulled backward from the inclined surface 241b of the first shielding removing portion 241, the shielding fastening protrusion 241a of the first shielding removing portion 241 is collected again and the second shielding portion 125 is removed. The engagement of the stepped fastening groove 126a is released.

Finally, as shown in FIG. 18, since the locking groove 126a of the second shielding portion 125 and the fastening protrusion 241a for removing the shielding of the first shielding removal portion 241 are released, the second shielding portion is released. The second shielding portion 125 can be removed from the clip device 200 by separating the first shielding removing portion 241 from 125.

As such, when the clipping in the biological tissue of the surgical indicator clip 100 and the release of the shielding of the radiation material 120a are completed, only the surgical indicator clip 100 is exposed to the biological material. Leave it on the target site of my life. In addition, by detecting the radiation material 120a emitted from the target region in the biological tissue using a gamma detector located outside the body, it is possible to quickly and easily find the exact position of the surgical indicator clip 100.

According to the present invention, the function of the indicator can be added to the basic role of the clip by including the radiation display unit 120 having the radiation material 120a embedded in the existing clip. In addition, an endoscope including a radiation material 120a capable of determining the exact position of the clip in the gastrointestinal tract using a gamma detector as a method of complementing the marking function of the surgical clip for determining the incision site during the incision procedure for treating gastrointestinal cancer. The treatment instrument has a shielding function of the radioactive material 120a. Therefore, the radiation may be exposed to the outside only after the operator and the patient are not exposed to the radiation continuously in the procedure using the surgical indicator clip 100, but the gripping the clip to the desired area. In addition, when using the surgical indicator clip 100 of the present invention, it is possible to increase the treatment effect by minimizing the incision area during treatment procedures such as colorectal cancer, stomach cancer, it is possible to minimize the side effects due to excessive incision. In addition, in addition to gastric cancer and colorectal cancer treatment as a placeholder that can easily and quickly find the desired area during various surgical procedures, the applicable field is very wide.

Although embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features thereof. I can understand that. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive. The scope of the present invention is shown by the following claims rather than the above description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.

The present invention can be used to manufacture a surgical marker clip and the like having a marking function for displaying the location so as to find the exact location of the biological tissue incision site during the surgical procedure.
