Description

{SURGICAL CLIP APPLIER}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a surgical instrument, and more particularly, to a clip applier for a surgeon who can easily secure a visual field during operation, easily perform a clipping operation, and shorten an operation time.

It is surrounded by three layers: the anatomical scalp, the skull, and the cerebral cortex. Therefore, when neurosurgical operations such as brain tumor, cerebrovascular disease, and traumatic brain injury are required, a drill is used to make a certain shape of the skull flap, and when the flap is separated from the skull, the brain dura is exposed . The exposed brain dura is incised with scissors in a "C" shape or a "U" shape, and then the brain is exposed.

After surgery for brain disease, surgical leakage is prevented, bleeding from the soft tissues enters the brain dura mater to prevent hematoma formation, and sutures are used to prevent adhesion between surrounding soft tissue and brain tissue The spermatocytes are sutured at intervals of approximately 5 to 7 mm.

This procedure is similar to the procedure of suturing after skin incision. The use of the smallest needle (suture needle) is necessary because the puncture of the brain membrane by the needle should be as small as possible in order to eliminate or minimize leakage of CSF.

The surgeon tries to make a knot by suturing the bilateral dura mater to the suture by hand and the first assistant makes a knot by hand, . This series of procedures is repeatedly performed at intervals of about 5 to 7 mm to prevent leakage of cerebrospinal fluid between the incised cerebral epidural space.

This inconvenience in the cerebral epidural suture is that nurses have difficulty in putting the suture into the ear of a small needle, which is one of the factors that prolongs the operation time, and on average, the length of the epidermis of the incision is about 20 cm, Because the epidural suture procedure is repeated about 40 times, the time required for suturing of the cerebral epidural membrane is long in addition to the time of neurosurgical operation for the cerebral disease, which is the main operation, resulting in an increase in general anesthesia as well as overall operation time . In recent years, there has been a case where a surgical clip is used to hold a portion to be bundled, that is, clipping.

Conventional surgical clips have a 'G clip' or a 'V clip' named according to their shape or structure. Such a conventional surgical clip has a problem that clipping is not performed properly and the clip is pulled out .

In addition, in order to perform clipping, an end of a clip applier is positioned at a desired position, and a force is applied by pulling the handle to deform the metal clip to tightly clamp the blood vessel or bile duct. In such a structure, There is a problem that it is difficult to use the clip when it is positioned in the parallel direction.

In order to solve this problem, Korean Patent Laid-Open Publication No. 10-2010-0089496 proposes a structure in which clips can be easily clipped merely by pushing the clips at a position to be held, and the ends of the clips can be fitted to each other And clip appliers that are capable of pressing the ends of the clips as needed to fully secure the clipped clips.

FIG. 1 is a side view showing a conventional surgical clip, and FIG. 2 is a plan view showing a surgical clip according to an embodiment of the present invention. The clip 10, the grip portion 12, the connecting portion 14, the wing portion 16, the hole 18, and the projection 19 are shown, as shown in Figs.

In the embodiment shown in Figs. 1 and 2, the surgical clip is normally closed by elasticity, and when the clipping is performed, the clips are configured to be held by the clips of the clips by the clip applier, Instead of deforming it, it is characterized by being robust and easy to clip by the force of pushing the clip apart.

3 is a cross-sectional view showing the end portion of a conventional clip applicator for clipping a surgical clip. A clip 10, a wing 16, a cannula 24, a pusher 26, a discharge portion 28, and a guide 30 are shown, as shown in FIG.

The conventional clip applier shown in Fig. 3 is normally closed, and when the clip is clipped, a pair of grip portions 12 are opened to be fitted at a desired point, and then closed again by elastic force, The clip applier 20 illustrated in FIG. 3 may be used to use the clip 10.

However, since such a clip applier has a structure in which the clip head can clip in a direction parallel to the body, it is difficult to clip the portion to be clipped in the lateral direction of the surgical site, It is very difficult to secure the field of view of the surgical site due to the surgical instruments such as an aphlier.

In the conventional clip applier illustrated in FIG. 3, in the case of the above-described brain disease suture surgery, the brain dura is thin, and there is sufficient space like other abdominal organs such as the abdomen, so that the clip applier approaches vertically, There is a disadvantage that it is very difficult to use the clipping method or apparatus for fixing the suture site in the suture operation of the brain disease.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

4 is a perspective view illustrating the structure of a clip applier for a surgical operation according to a preferred embodiment of the present invention. As shown in FIG. 4, the surgical clip applier according to the embodiment of the present invention includes a clip head portion 100 formed by two grippers for attaching and clipping a clip; A body part 200 formed by coupling two rods 210 and 230 bent and extended at a predetermined angle with the respective claws; And a grip part 300 composed of two legs 310 crossing each other so as to be offset from the bars 210 and 230 of the body part 200 and in which one of the legs 310 is hinged And the clipping operation of the clip head unit 100 is driven by the operation of the hinge-rotating leg 310 connected to any one of the claws by a wire.

As such, unlike the conventional clip applier, the clip applicator for surgical operation according to the embodiment of the present invention includes a clip head unit 100 for performing a clipping operation, a handle for gripping by a user to drive the clipping operation, The clip head 100, the body 200, and the handle 300 are formed as a pair, and one of them is fixed to form the handle 300, The clip applier of a new structure that performs the clipping operation by the rotation of the clip 300 can be easily made by providing a mechanism close to the surgical site at a certain inclination angle to secure the visual field and to clip the clip head .

In addition, since the clip head unit 100 and the grip unit 300 connected to each other via the wire clip only one of the fixed grip units 300 by the turning action of the other grip unit 300, the shaking during clip operation is reduced Since the operation is performed more stably, the clipping process is facilitated, the operation time is shortened, and more precise clipping can be performed.

Hereinafter, each component of the clip applier according to the embodiment of the present invention will be described in detail with reference to FIG. 4, the clip head unit 100 is preferably composed of a fixed one of the fixed claws and a pivoting claw 130 hinged to one of the bars 210 of the body 200 .

Here, the clip head unit 100 is configured such that a clip having a bent structure in which one of the "U", "V", or "C" type is opened and the opposite side is bent is inserted and mounted, And then clamped and clipped. That is, when the gripper is gripped like the gripper, the clip is pressed and clipped to the sealer. The gripper 130 comprises a fixed gripper and a hinge. The gripper 130 rotates And a clipping structure is proposed.

Here, it is preferable that the material of the clip is made of a strong metal such as titanium or a plastic material. In the case of the clip for surgery, since blood or body fluids are buried in the use thereof, It is preferable to use a metal alloy or plastic material, and it should remain in the inside of the human body, so it is preferable that the material is not harmful to the body.

As described above, in the embodiment of the present invention, instead of performing a clipping operation in which a pair of the claws are rotated and moved away from each other, the rotating claw 130 is pivoted to a fixed one of the claws, And clips the clips.

It is preferable that the clip head 100 of the clip applicator according to the embodiment of the present invention is formed in a structure bent at a certain angle with the straight body 200. This is because, in the case of a clip head in a direction parallel to the conventional body part 200, it is difficult for the medical staff to perform the operation such as clipping due to difficulty in securing the viewpoint of the surgical site when the clip head part 100 approaches the surgical site It is very difficult to clip the clip head 100 in a vertical direction when the sewing part is laid horizontally so that the clip head part 100 is inclined at a predetermined angle with respect to the body part 200 of the straight bar 210, It is very easy to approach the suture site for clipping.

In the clip applier according to the embodiment of the present invention, as shown in FIG. 4, the body part 200 is formed such that two rod-shaped plates are respectively connected to the claws of the clip head part 100 and each of the knob parts 300 As shown in FIG. The clipping operation in the present invention forms a structure in which the clip mounted with the rotating pincers 130 of the clip head part 100 is rotated while being driven by the pull part 300 to be clipped, 100 and the grip 300 are connected to each other by a wire for transmission of driving force and are not exposed to the outside because they are connected to each other through the longitudinal direction of the body part 200 described above.

In the clip applicator according to the embodiment of the present invention, the handle 300 may be bent and connected to the body 200, It is preferable that the grip portion 300 is folded in a direction opposite to the bending direction of the body portion 200 and the clip head portion 100. The grip portion 300 includes a hook Is preferably formed.

4, the grip portion 300 of the clip applicator according to the embodiment of the present invention corresponds to a driving portion for driving the clipping operation by the hand of a medical staff, and is formed as an end portion of the handle-like shape of the scissors, And two legs 310 crossing the bars 210 and 230 of the body 200 so as to be offset from each other. One of the legs 310 is connected to the rod 230 of the body part 200 by a hinge to form a structure that rotates to drive the clipping operation.

One leg 310 of the handle 300 forms an integral structure extending from the body 200 to the clip head 100 and the other leg 310 is connected to the rod 200 of the body 200 When the legs 310 of the handle 300 are pivoted by connecting the wire to the pivoting claw 130 of the clip head 100 through the inside of the body 200, So that the rotating nib 130 of the clip head 100 rotates to form a clip.

4, the plate connecting the inner sides of the two legs 310 of the handle 300 is fixedly connected to the legs 310 by a diagonal line, The tension unit 330 maintains an elastic force to open the cover 310 to the maximum extent.

The tension unit 330 is an apparatus for maintaining the opened state of the clip head unit 100 so that the clip applicator can easily insert the clip in a normal state. The tension unit 330 is made of a material having an elastic force inside the leg 310 of the grip unit 300 And the plate of FIG. When the plate of elastic material is fixedly connected to the inside of each leg 310, the opening of the grip 300 is maintained, and the clip 310 connected to one of the legs 310 of the grip 300, The pivoting claw 130 of the head unit 100 is pushed to maintain the open state.

The medical staff can easily insert the clip into the clip head unit 100 opened during the suturing operation. When the clip is docked in the state where the clip is mounted and the grip 300 is gripped and driven, The rotation nippers 130 of the body 100 rotate and clips. Then, when the clip is folded at the stitching site and the medical staff releases the grip 300 again, the clip head 100 is opened by the elastic force of the tension unit 330, . By providing the plate-shaped tension part 330 inside the both legs 310 of the grip part 300, not only the clipping process of the sewing part is made easy by the simple operation, but also the whole sewing operation time Can be shortened.

4, it is preferable that the tension part 330 has a structure in which one side is fixed to the inside of the leg 310 of the handle 300 and the other side is formed with a wide through groove and a bolt is spanned. This is because when one of the knobs 300 is closed, the plate can be extended to secure a moving space in which the through-hole on which the bolt is stretched is pushed and slid. That is, by forming the sliding connection structure with the tension unit 330, the gripping operation of the grip 300 is made smooth, and when the gripping force is not applied, It is possible to provide a structure for maintaining the state.

FIG. 5 is a view showing a clip head unit 100 bent at various angles in a surgical clip applicator according to an embodiment of the present invention. The clip head unit 100 of the clip applicator according to the embodiment of the present invention includes a fixed fixed claw and a pivoting claw 130 hinged to one of the bars 230 of the body part 200 And the angle at which the fixing claws are bent with the rod 210 of the body 200 may be any one of 15 degrees, 45 degrees, and 65 degrees and 90 degrees with respect to the rod 210. Of course, it is also possible to provide a clip applicator formed by bending the clip head unit 100 at the most suitable joining angle, taking into consideration not only the illustrated angle but also various environments and surgical conditions.

Since the clip head unit 100 is bent and connected to the body 200 at a predetermined angle, it is possible for the medical staff to easily secure the visual field of the surgical site and to easily access and clip the various parts of the shape and position .

As shown in FIG. 5, it is preferable that the clip head unit according to the embodiment of the present invention is formed such that the opposing face of the end portion is spaced apart when the nippers are closed.

As described above, in the conventional clip applier, when the clip head unit 100 is linear and approaches the clip applicator to the sewing site for clipping, the position of the clip applicator becomes perpendicular to the sewing site, There is a problem that it is difficult to dock the clip applier to the suture site because the space of the surgical site is narrow.

Accordingly, in the embodiment of the present invention, when the clip head unit 100 is bent and connected to the rod-shaped body 200 at a predetermined angle, the body unit 200 can be positioned at an angle to the sewing or surgical site It is easy to secure the visual field and it is very advantageous to use the clip applier of various angles to easily dock or access the sewing area.

The clip applier according to the embodiment of the present invention as shown in FIG. 5 has a structure in which the clip head 100 is connected by bending at an angle of 45 degrees (left side) and 90 degrees (right side) with respect to the rod 210 of the body For example. As such, when the clip head 100 can use a clip applicator having a structure having clip heads 100 at various angles with respect to the body, it is possible to easily access and dock more complicated and difficult position and shape seams, So that clipping can be facilitated and the operation time can be further shortened.

The embodiments and the accompanying drawings described in the present specification are merely illustrative of some of the technical ideas included in the present invention. Accordingly, the embodiments disclosed herein are for the purpose of describing rather than limiting the technical spirit of the present invention, and it is apparent that the scope of the technical idea of the present invention is not limited by these embodiments. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
