Description

Suture insert kit with locking chuck

The present invention relates to a suture insert kit useful for connecting or fixing animal tissue in various medical environments, and more particularly, a suture insert having a chuck to fix the suture on a handle of an insertion needle. The present invention relates to a suture insert kit having a locking chuck which can prevent the fixed suture from being displaced at a fixed design position in the process of transporting, storing, manipulating and using the product.

In general, sutures are used to connect or suture various injured areas of animal tissues such as skin, muscles, tendons, internal organs, bone tissues, nerves, blood vessels, etc. and incision sites according to surgical procedures.

These sutures are typically made of materials such as silk, cotton, nylon, dafilon, polyester, polypropylene, or stainless steel. Air between the absorbent suture and the l-lactide polymer, the glycolic acid polymer, the copolymer of lactic acid and glycolic acid, or their respective polymers and copolymers with caprolactone or trimethylene carbonate Bioabsorbable sutures are composed of a material such as coalesced or polydioxanone, or chitosan and derivatives thereof.

In particular, such bioabsorbable sutures provide the convenience of use since there is no need to remove the sutures from the patient.

In the use of such a suture, the idea and design of using a suture in an insert needle for the convenience of a user's suture has been started since the 1990's. Based on a more active research on tissue elevation, sutures are being used for a variety of purposes beyond simple sutures.In this way, the method of using the sutures described above on a support such as an insertion needle is used for sutures. In the field of tissue cohesion utilized, it is one way to provide user convenience in many ways.

In this case, the suture is inserted into the body by inserting a part or all of the suture into the needle, and the suture is inserted into the body at the same time as the needle is inserted into the body. However, the inventions of the design that do not fix the suture to the needles are used in the production of the product (especially in the process of repetition or packing of pressure and pressure for sterilization) and in the process of transporting, storing, manipulating and using the product. There was a problem in that the suture inserted into the needle was separated from the needle or a displacement occurred in the set suture insertion position.

In addition, the occurrence of such a problem has a disadvantage in that it is difficult to insert the suture up to the position designed by the operator.

As a conventional technique for solving such a problem, Korean Patent Registration No. 10-1261175 (April 29, 2013), in the anti-wrinkle molding thread inserting device, inserting the molding thread into the muscles of the human body by the insertion needle In the thread inserting device for strengthening the muscles by the autogenous material by inserting to induce the intrinsic material in the body around the molding thread, the tubular thread having a thread insertion hole for inserting the molding thread into the inner hole of the insertion needle The insertion inner tube is inserted and installed to be movable back and forth, and the length of the thread insertion inner tube is formed longer than the length of the insertion needle so that the rear of the thread insertion inner tube protrudes from the rear of the insertion needle so that the thread of the inner tube tip for the thread insertion Insert the molding needle into the muscle by inserting the insertion needle and the inner tube for inserting the thread into the muscle of the human body with a part of the molding thread inserted into the insertion hole. Yeoseo a thread insertion device for anti-wrinkle cosmetic according to claim made to effect improved skin elasticity and wrinkles are known by strengthening the muscles.

However, the above-described anti-wrinkle molding thread inserting device is a design that does not fix the sutures or insert the sutures to the insertion device to the position designed by the operator. Therefore, as described above, the invention is a position designed by the operator because the suture inserted into the hollow of the needle occurs in the process of transport, storage, manipulation, use, etc., because the displacement occurs in the needle insertion position or the suture insertion position is set. The disadvantage is that it is difficult to insert until.

As another conventional technology, Republic of Korea Patent Registration No. 10-1060722 (August 24, 2011) in the injection needle equipped with a wrinkle removal surgery, the injection needle for inserting the wrinkle removal surgical In, the tip is pointed to be injected into the human body and two or more surgeons are formed with a plurality of projections formed in the hollow cylindrical injection portion, the surgeon is formed with a plurality of projections having different directions 1 Molding needles are known that are equipped with a surgical remover for wrinkles, characterized in that formed to a length of ~ 3cm.

However, the same injection molding needle equipped with the above-described wrinkle removal surgery doctor is a design that does not fix the suture on the insertion device, so the disadvantages are there.

As another conventional technology, Korean Patent Registration No. 10-1307308 (September 03, 2013) includes a needle kit for inserting a suture, a body and a needle member connected to a needle on one side of the body; A handle member detachably coupled to the other side of the body; A suture member which is partially inserted into the needle and partially exposed to the outside of the needle; And a holding member which is movably inserted on the needle and fixed to a position where the suture member exposed to the outside is inserted, and a plurality of suture members inserted in the needle member are not separated from the suture member inserted into the needle. A needle kit for inserting a suture is characterized in that the needle kit for inserting a suture is characterized in that the protrusion member protrudes.

The needle kit for inserting the suture can prevent the displacement of the suture inserted in the needle in the insertion process or operation of the suture due to the role of the holding member performing the role of fixing the suture and the needle, the desired position of the suture It is possible to insert into the body.

However, in the needle kit for inserting the suture, the suture is damaged due to the friction between the suture and the holding member during the insertion process of the suture, and thus the suture is lost or the holding member is broken. There are serious drawbacks that can be introduced into the system.

In addition, if the protruding member formed on the suture is formed long, there is a serious disadvantage that the suture or suture of the suture or the suture of the suture or the suture due to friction between the protruding member and the holding member may lose the function of the suture or the protruding member.

In addition, the part where the holding member is located is a part of the suture is strongly adhered to the holding member, it is difficult to infiltrate the sterile gas into the suture part of the corresponding part when performing EO gas sterilization, which is a commercially sterilized commercial method in the product. There is a problem. This causes a serious problem that a portion of the suture inserted into the body is not fully sterilized.

And as a conventional technology invented by the applicant, Republic of Korea Patent Registration No. 10-1384126 (04 04, 2014) in the suture insert kit, consisting of a needle and a handle and formed a hollow groove in the longitudinal direction therein And a protective cap for receiving and protecting the needle and suture by forming an accommodating groove therein to prevent breakage and contamination of the needle and suture of the needle. The needles are known suture insert kits, characterized in that to form one or more slit grooves to fix the suture to the rear end of the handle.

However, the suture insert kit is a structure having a limit to firmly secure the suture because the suture is fixed using a simple slit groove. As a result, when the suture is inserted by forming a slit groove finely to secure the suture, the suture is damaged and the suture fixing becomes unstable when the slit groove is formed to a sufficient width.

In addition, this problem is more prominent in the barbed suture made of synthetic absorbent material having barbs formed on the surface. Generally, the absorbent suture is a relatively soft material, and the suture is inserted into the slit groove while preventing the damage of the fine barb including the soft suture itself. To be inserted and fixed, the slit grooved structure must be softer than the suture.

However, the slit groove formed of a material having excellent ductility has a problem that the fixing is incomplete due to a lot of movement due to its ductility.

The present invention is to solve the problems as described above, by having a locking chuck (fix) to fix the suture on the handle of the insertion needle by fixing and protecting the suture to the insertion needle transport, storage, operation The technical problem is to provide a suture insert kit with a locking chuck which prevents the fixed suture from being displaced in the fixed design position and inserts the suture accurately into a desired position.

In addition, by providing a locking chuck to secure the suture on the handle of the insertion needle, the suture is fixed to the insertion needle to secure the suture with a softer material than the suture material. It is a technical object of the present invention to provide a suture insert kit having a locking chuck capable of preventing damage to the barbs and damage to the barbs.

The present invention provides a suture insert kit having a locking chuck made of an insertion needle including a handle provided with a locking chuck to fix the needle and the suture formed with a hollow groove in the longitudinal direction.

The needle 11 is a hollow groove larger than the diameter of the suture 50 in the longitudinal direction is formed in the inside of the needle 11 so that some or all of the suture 50 may be inserted.

The needle 11 may be formed in various shapes such as a needle in which one end is sharply formed or a cannula-shaped needle in which one side of the needle is blocked and an open part of the side is opened, as is typically used in a surgical procedure. It is possible to apply selectively to suit the situation.

The handle 12 is fixed to the rear end of the needle 11, it is configured to facilitate when the user inserts or withdraw the needle (11) in the human body. The handle 12 may be formed in a cylindrical shape or may be formed in various shapes as shown in the figure so as to be easily used by holding with a finger.

In addition, the handle 12, as shown in the [Fig. 4] and [Fig. 7] it is possible to form a hollow groove through the inside, the suture 50 is a needle (from the rear end of the handle 12 ( It can be configured to be inserted into the insertion needle 10 to pass through the tip portion of 11).

On the handle 12, as shown in FIG. 1 and FIG. 2, a locking chuck 30 capable of fixing the suture 50 is provided. At this time, the locking chuck 30 is formed of the collet 31 and the locking ring 33 together.

As shown in FIGS. 7 to 9, the collet 31 has one or more slit grooves 32 formed therein, and the locking ring 33 is inserted into the collet 31. It is formed into a structure in which a force applied in the direction is applied.

The suture 50 may be fixed by fitting the locking ring 33 to the collet 31 in a state sandwiched between the slit grooves 32 of the collet 31 as shown in FIG.

The handle 12 may be formed in various ways, but by fastening the locking ring 33 with a small force to facilitate the fixing of the suture 50, the suture being pressed and fixed by the locking chuck 30 ( In order to prevent the damage of 50), it is preferable to form a soft material. At this time, considering that the material of the biodegradable suture 50, which is commonly used, is relatively soft, the handle 12 is made of silicon of moderate hardness as a whole. It is desirable to form a soft and flexible material.

In addition, the handle 12 may be formed in a combination of two or more materials. For convenience of use, when the handle 12 is formed of a hard material such as plastic or metal of high hardness, As shown in FIG. 7 to FIG. 9, the collet 31 components are separately formed of a flexible and soft material such as silicon.

At this time, the collet 31 formed of a different material can be combined on the handle 12 by a method such as bonding, bonding, or fitting, and a special injection method such as double injection molding one product into two materials. It can be formed without any difficulty.

The locking ring 33 may be formed in various shapes so as to fit into the collet 31, the simplest form of the collet 31 in the shape of the cylinder as shown in FIG. Create a hollow groove corresponding to the shape to form.

The material of the locking ring 33 is preferably formed of a material having a low coefficient of friction so as to facilitate fitting with the collet 31, and is most preferably composed of a Teflon material.
