Description

[0001] SURGICAL CLIP AND CLIPPING DEVICE FOR LIGATION [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip and clip device for ligation, and more particularly to a clip and clip device for ligation, And a clipping device for effectively clipping the protruding tissue by attaching a clip, thereby minimizing various side effects caused in the ligation procedure and improving the difficulty in the operation of the local site. .

Generally, surgical clipping is performed for the purpose of clipping or suturing the tissue site using a clip when the lesion inside the body is treated by surgical operation.

Therefore, the ligation technique is effective when the tissue region is in a protruded shape, and is widely used, for example, in the treatment of dental pulp and various polyps.

The ligation procedure is roughly classified into a method in which the tissue is immediately cut and removed, and a method in which the root portion of the tissue is tied with a rubber band or a ring type ligation means and is removed by suturing or spontaneous removal.

The former method may cause side effects such as excessive bleeding at the cleavage site or prolonged recovery period. Recently, the latter method has been mainly performed, and as a representative example thereof, The band-type ligation device through the band ligation device and the device for ligating the same to the tissue will be described as follows.

A plurality of bands are formed on the outer surface of the body 10 and a plurality of bands are mounted on the outer surface of the body 10 such that the bands are engaged with the engaging grooves The band under and the band are zigzagged in the front and rear directions and the end is guided to the outside and wound around the drum 6 of the controller 5 to rotate the drum 6 to pull out the yarn, In a ligature for ligating a lesion site,

The retaining grooves a, b, c, d, e, ..., a ', b', c ', d', e ' Is formed in a ring shape having both ends connected to each other so that one side of the thread 9 is moved from the front to the rear under the first band 20 in a state in which the one side of the thread 9 is hooked to the first and second fastening grooves a and a ' The first band 20 is bound to move back from the rear to the front,

The yarn 9 moves from the rear to the front of the second band 21 and moves from the rear to the front and backward from the rear to the front of the second band 21 on the left and right sides, And binding the plurality of bands in such a manner as to be engaged with the grooves (b, c) (b ', c') and binding the second band (21).

Registration No. 10 - 0548873 Patent No. 10-1298521 Published Patent No. 10 - 2009 - 0091380

The medical band ligation machine to which the conventional technique as described above is applied has a configuration in which a plurality of bands are threaded into a body and the lesion tissue is ligated while the bands are moved one by one by an operation of inserting the thread into the body.

However, the ligation device in the form of a rubber band, such as the band ligation device, tends to exhibit a difference in ligation strength depending on the type of tissue to be ligated, resulting in easy detachment of the clip from the tissue or disturbance of blood supply to the periphery of the lesion tissue Resulting in serious side effects such as tissue necrosis and the like.

This side effect is caused by ligating the tissue by the ring type ligation device which is generally used only depending on the self elasticity. In particular, when the ridge pattern of the ligature to be ligated forms a gentle curve or is located in the deep part of the body, Because the ligation procedure is not easy, there is a great difference in the surgical outcome depending on the know-how of the operator.

Accordingly, the present invention has been made to solve the above-mentioned problems,

The upper leg 110 and the lower leg 120 are connected to each other so that the upper leg 110 and the lower leg 120 are connected to each other and the upper leg 110 and the lower leg 120 are mutually opposed to each other And a folding leg (130) folded in a closing operation in which the inner side is connected;

(110) and the lower leg (120) are formed in a closed state by using a raw material synthesizing one or more kinds selected from a polymer having a certain elasticity and strength, nitinol and a shape memory alloy, Thereby forming a ligation clip for keeping the closed state after clipping the bulge tissue in the open state.

A ligation unit 210 having a driving clamp 211 and a fixed clamp 212 facing each other to attach the ligation clip 100 and the ligation unit 210 provided at the front end are inserted into the body A body 220 having a handle 221 formed at a rear end of the body 220 so as to be gripped by a practitioner and an inner hollow 222 of the body 220 connected to the driving clamp 211, And a switch (230) for driving the driving clamp (211) up and down by operating the sliding bar (231) extending in the pulling-in or pulling-out direction;

A clip 300 is provided so that the ligation clip 100 is seated and a clip 100 is attached from the cartridge 300 to be inserted into a lesion occurrence site of the body to constitute a ligation clip device for clipping the ridge tissue.

Therefore, it is possible to minimize the various side effects caused by the conventional ligation technique through the clipping clip device and to improve the difficulty in the local operation.

The present invention is characterized in that a ligation tool used for ligation is peeled from a general form such as a conventional band or ring type to constitute a clip having a stronger ligation force and a ligation tool for effectively ligation to a tissue site by attaching a clip There is an advantage that the possibility of clip release during surgery or after surgery can be excluded.

Therefore, it is possible to relieve the burden on both the surgeon and the patient because it is relatively easy to ligate the tissue even when ligation of the local site or the deep part of the body is very difficult, and the occurrence of various side effects can be minimized, And a satisfactory result is obtained.

The clip 100 is inserted into the body at the time of the ligation procedure to receive the ridge tissue and securely ligate the root portion of the tissue to remove the tissue. Accordingly, the upper legs 110, the lower legs 120, and the folding legs 130 connecting the opposite sides of the upper legs 110 are integrally formed to receive the raised tissue in the inner space.

The clip 100 may be formed by using a raw material synthesized from at least one material selected from a polymer having a certain elasticity and strength, nitinol, and shape memory alloy, so that the original shape of the clip 100 is separated from the upper leg 110, The legs 120 are configured to be in a closed state and are configured to maintain closure after clipping the elevated tissue in an open state.

Since the individual characteristics of the raw materials described above are already well known, a detailed description thereof will be omitted. Among them, particularly, the raw materials have a shape memory effect to return to a circular shape at the time of molding even if the shape is deformed by external force. It is very effective to use as a raw material of the clip 100 of the invention.

The upper leg 110 and the lower leg 120 of the clip 100 are provided with a pair of fixing pins 111 and 121 for fixing the upper leg 110 and the lower leg 120 in a closed state And a pair of fixing hooks 112 and 122 corresponding to the fixing pins 111 and 121 are diagonally arranged on the left and right sides so as to be mutually engaged.

Therefore, when the clip 100 is closed during clipping of the tissue, the fixing hooks 112 and 122 are fastened to the fixing pins 111 and 121 provided on the upper leg 110 and the lower leg 120, respectively, So that the lesion tissue may have a gentle uplift pattern or may be effective in preventing the problem that the clip 100 is separated from the tissue in response to stimulation by the movement of the body.

In the embodiment of the present invention, the fixing pins 111 and 121 are formed to protrude in the form of a pin having a circular cross section to facilitate fastening with the fixing hooks 112 and 122 having a semicircular shape. However, May be formed in various forms. In addition, a slope is formed at one side of the fixing pins 111 and 121 in the fastening direction of the fixing hooks 112 and 122 to induce more natural fastening. However, it is also possible to deform the fixing hooks 112 and 122 as well.

It is effective to describe this in detail in connection with the operation state of the clip 100 and the clip device 200, which will be described later.

The folding leg 130 of the clip 100 is formed with a folding hole 131 to prevent the folding leg 130 from being formed in an unnatural folding state due to the difference in thickness between the inner and outer sides during clipping, 100 to be opened or closed.

A plurality of coupling protrusions 113 may be formed on the inner side surfaces of the upper leg 110 and the lower leg 120 facing each other to enhance the ligation strength of the raised tissue, ) Can be additionally attached. Thus, the possibility that the clip 100 may slip away from the raised tissue after clipping is excluded.

The clip device 200 is configured to have the cartridge 300 so that the ligation clip 100 is seated thereon and attach the clip 100 from the cartridge 300 to insert it into the lesion occurrence site of the body to clump the ridge tissue .

The cartridge 300 in which the ligation clip 100 is stored includes a case 310 for accommodating the clip 100 and a pair of protrusively formed protrusions formed on the bottom surface of the case 310 to support the inner side surface of the received clip 100. [ The clip holder 320 is provided to seat the clip 100 in an open state so that the clip apparatus 200 can easily attach the clip 100.

In addition, at least one clip 100 may be seated in the clip seating part 320 to facilitate the attachment of the clip 100 to the clip device 200 during the ligation procedure, It is easy to accept and ligature.

The clip device 200 is roughly divided into a ligation portion 210 at the front end, a body portion 220 at the middle region and a switch 230 at the rear end. Among them, the ligation portion 210, which is a substantial portion of the clip device 200, The ligation clip 100 is attached by the opening and closing operations of the driving clamp 211 and the fixed clamp 212 to clump the tissue.

The driving clamp 211 includes a first bending portion 213 having a sliding bar 231 extending or drawn out from the outer end of the body 220 into the inner hollow 222, And a first annular portion 214 to which one side is attached.

The fixing clamp 212 includes a second bent portion 215 fixed to the inner side of the front end of the body portion 220 and bent to the 'A' shape, and a second bending portion 215 ' (216).

When the switch 230 connected to the sliding bar 231 extended from the driving clamp 211 is operated in the pull-in or pull-out direction, the driving clamp 211 drives the fixing clamp 212 upwards and downwards The clip 100 mounted on the inner side of the first holding portion 214 and the second holding portion 216 is deformed from the open state to the closed state.

At this time, a rail groove 217 is formed on the inner side surface of the first annular portion 214 and the second annular portion 216 opposite to each other, And the clip 100 is placed in the rail groove 217 in a sliding manner.

Hereinafter, an operation state of the ligation clip using the clip according to the present invention will be described in more detail.

Of course, several cartridges 100 may be sequentially placed on the cartridge 300, and the cartridges 300 may be sequentially attached to the cartridges 300 by using the clip device 200 during the ligation procedure.

The operator grips the handle 221 of the body part 220 and operates the switch 230 to move the sliding bar 231 to the tip of the body part 220, .

As the sliding bar 231 is drawn out, the driving clamp 211 is driven upward from the fixed clamp 212 to be opened to each other as shown in FIG.

5, the ligation unit 210 of the clip device 200 is positioned at one side of the folding leg 130 on one side of the clip 100 that is seated on the cartridge 300 and the driving clamp 211 And enters the first groove 214 of the stationary clamp 212 and the rail groove 217 of the second groove 216 in a sliding manner.

6, the folding leg 130 is initially positioned inside the first bending portion 213 and the second bending portion 215, and the upper leg 110 is positioned in the first folding portion 213 and the second folding portion 215, Are respectively seated in the inner rail grooves 217 of the inner ring portion 214 and the inner rail grooves 217 of the second inner ring portion 216 of the lower leg 120 respectively.

7, when each part of the clip 100 is seated on the clip device 200 as described above, when the clip device 200 is lifted up vertically from the cartridge 300, And is detached from the cartridge 300 in a state in which the cartridge 300 is fully attached to the cartridge 200. At this time, since the engaging pins 114 and 115 of the clip 100 are interlocked with the engaging protrusions 218 of the clip device 200, they can still be kept open.

The clip 100 attached to the clip device 200 is placed in the body to be ligation or in the extracorporeal lesion generation site and in a state in which the raised tissue is accommodated on the inner space of the clip 100 in an open state, 9, the driving clamp 211 and the fixing clamp 212 are clipped to close the clip 100 so that the clip 100 is closed.

That is, as shown in FIG. 10, when the driving clamp 211 is opened upward in the direction of the fixed clamp 212, the raised tissue is received on the inner space of the clip 100, The driving clamp 211 is closed in the downward direction of the fixed clamp 212 together with the sliding bar 231 so that the clip 100 is deformed into the closed state, The root canal is ligated between the coupling protrusion 113 of the clip 100 or the ligature tooth 116.

When the clip device 200 is detached from the clip 100 in a sliding manner after the clip 100 is ligated to the tissue as described above, the clip 100 is kept in the closed state and at the same time, the upper leg 110 and the lower leg 100 The fixing hooks 112 and 122 are automatically engaged with the fixing pins 111 and 121 while the cover 120 is closed so that the ligation of the tissue can be maintained in a more solid state.

The clipping and clip device according to the present invention has the advantage of increasing the ligation strength of the clip with respect to the tissue site, thereby eliminating the possibility of the clip being removed during surgery or after surgery. Therefore, it is possible to increase the satisfaction of the surgical procedure and the surgical procedure when the ligation of the local site or the deep part of the body is performed, and it is possible to minimize the occurrence of various side effects and to expect a quick recovery after surgery.
