Description

An Automatic Clip Applier for a Surgical Operation

The present invention relates to a medical clip applier, and more particularly, to a medical automatic clip applier that allows a clip to be prevented from being released during a surgical procedure.

Medical clips may be used for gripping or resecting a human organ extending in the longitudinal direction, such as a blood vessel or cecum, during an intra-human surgical procedure. For example, clips are used to grasp, ligature, or bleed the appendix or blood vessels during an appendectomy procedure. Such a medical clip may be made of, for example, a resilient metal or polymer material. A number of clips may be sequentially placed on the apple lyre for ligation of a part of the body, such as a part of the blood vessels or cecum during the surgical procedure. And before using the clip, the Apple lyre may be sterilized or sterilized or left unattended for extended periods of time. If the Apple lyer is in this state, the physical properties, such as the elasticity of the clip placed inside it, can change, which can lead to the jaw unit placed at the end of the Apple lyre and cause the clip to separate during use. Also, since a plurality of clips are successively placed in the supply tube of the Apple Liaer, the clips placed on the rear side may change their physical properties over time. Thus, there is a need for a clip applier that maintains the physical characteristics of the clip before use and can be used stably in the surgical procedure.

Various clip movement schemes may be applied to the appliers according to the present invention and the present invention is not limited to the embodiments shown.

2C and 2D show an embodiment of a guide unit applied to a spare unit according to the present invention.

Referring to FIG. 2C, a restriction plate 24 is formed in the guide channel 15 so that the clip C disposed inside the guide channel 15 can be stably disposed. The clip C is held in a state of being transmitted to the jaw unit while the clip C is accommodated in the guide channel 15. [ In such a state, the clip C is subjected to a process of transportation, storage, sterilization or sterilization. As a result, the physical state of the clip C can be maintained in a state of being transferred to the coarse unit and the clip C can be prevented from being detached from the coarse unit. To this end, the width of the guide channel 15 may be determined according to the state in which the clip C is fixed in the jaw unit.

Referring to FIG. 2D, a width adjusting region 26 may be formed at a portion where the guide channel 15 and the guide tube are connected. The end of the width adjusting area 26 may be set to be equal to or similar to the width of the guide tube. Generally, the clip (C) in the guide tube can be maintained in a state where both branches are approaching. And the clip (C) is transferred from the guide tube to the jaw unit and both branches of the clip (C) can be spaced apart in the course of ligation or gripping. If the clip C is held in the induction tube for a long time or is placed in the induction tube and is kept at a high temperature for a certain time for sterilization or sterilization, the clip C may lose its elasticity or other physical properties may be denatured . And the clip C may not operate in the required form. The applier according to the present invention prevents deformation of the physical properties of the clip, thereby enabling the clip C to operate stably.

The guide channel 15 may have an appropriate width depending on the use state of the clip C. [

Below is shown an embodiment of a clip (C) that may be applied to an apple according to the present invention.

Figure 3 illustrates an embodiment of a medical clip accommodated in an apple lie according to the present invention.

Referring to FIG. 3, the medical clip 30 applicable to the apple according to the present invention includes a pair of elastic members, which can be made of elastic polymer, metal, or non-metal material and form a certain range of separation angle by elasticity And may include separate branches 31 and 32. Each of the pair of separate branches 31 and 32 may be, for example, a rod shape having a circular cross section or a polygonal cross section, and one end may be connected to each other. And a through clearance space 34 may be formed on the side of the connected end. The clearance may have a different shape with respect to the connecting portion, and may be suitably determined in consideration of, for example, an extension length of each of the separating branches 31 and 32, a cross-sectional area size, or a relative movement distance in the proximity process. For example, if the first separating branch 31 is smaller in length than the second separating branch 32, the through-hole clearance space 34 has a relatively large width and a small length in the direction of the first separating branch 31 Lt; / RTI >

Fixing grooves 321a and hooking hooks 321 may be formed on both ends of the pair of separate branches 31 and 32, respectively. In the ligation process, both ends of the pair of branch branches 32 are connected to each other, and thereby the inner side of each branch branch 31 becomes close to each other. This condition is maintained during the operation and hemostasis or fixation to the blood vessels is required. The fixing groove 321a and the hooking hook 321 are thus held in a state in which the pair of separate branches 31 and 32 are held close to each other.

The fixing groove 321a may be formed into a wedge shape, and the hooking hook 321 may be formed into a hook shape. Specifically, the fixing groove 32 may have a wedge shape in which the two sides of the triangular shape extend downward and the width of the fixing groove 32 increases toward the outside of the separating branch. The hook hook 321 may have a structure in which a sharp end is formed while being bent inward. The balance unit 322 may be formed on both ends of the split branches 31 and 32 as necessary. The balancing unit 322 allows both ends of the separating branches 31 and 32 to be relatively heavy compared to other portions so that the coupling between the fixing groove 321a and the hooking hook 321 can be stably maintained.

A plurality of step blocks 33 may be formed on the inner surfaces of the respective branch branches 31 and 32 facing each other. The step block 33 allows the surface of the organ inside the fixed body to be slippery, thereby preventing the clip 30 from moving or slipping along, for example, blood vessels. In other words, it ensures the stability of the ligature.

The step block 33 may have a rectangular plate shape and one side may be formed so as to share the outer side of the inner side. And a plurality of portions may be disposed so as to be offset from each other along both sides of the inner surface. The length extending inward of each step block 33 is not particularly limited. The height of the step block 33 may be appropriately set according to the cross-sectional area of the portion to be ligature or the characteristics of the material. Various step blocks 33 may be formed on the inner side of each of the branch branches 31 and 32. [

The applier according to the present invention allows the separate branches 31, 32 of the medical clip 30 to operate in the required state.

 The appliers according to the present invention prevent the physical properties of the clip from changing during the sterilization or sterilization process, thereby preventing the clip from being separated from the jaw unit. In addition, by allowing the clip to move to the jaw unit during the surgical procedure, the defects of the clip are reduced. In addition, the applier according to the present invention makes it possible to simplify the sanitary treatment required for the clip.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, 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 . The invention is not limited by these variations and modifications, but is limited only by the claims appended hereto.
