Description

Disposable Surgical Opening Apparatus

The present invention relates to a disposable surgical retractor (surgical retractor) and a device for manufacturing the disposable surgical resection apparatus, and more particularly, it can be easily fixed to the surgical incision site to reduce the operation time to a minimum and wine The member is designed to be firmly fixed while being rolled up, and to ensure the safety of the surgery, as well as to an apparatus for manufacturing a disposable surgical open apparatus that can be easily removed after surgery.

In general, laparoscopic surgery refers to a small hole around the navel, and then laparoscopic surgical instruments are inserted into the cholecystectomy instead of the usual surgical procedure, which is a general operation that is performed freely using various surgical instruments through a large surgical window. It is said that it is possible to perform surgery. The retractor serves to secure the surgical range by expanding and supporting the incision in the open state during surgery.

The conventional opening mechanism is disclosed in Japanese Utility Model Publication No. 2,131,233.

The conventional opener disclosed in the above publication includes a so-called nasal speculum, and the incision can be expanded by inserting the tip portion of the parenteral into an incision and closing gripper.

However, the conventional opening mechanism has a disadvantage in that it is difficult to support the incision in the open state to a certain range because the user must keep the gripper closed during the operation.

An ecarteur that supports the incision to a certain range is disclosed in Japanese Patent Laid-Open No. 9-234,204. The dilator has a pair of branches arranged parallel to each other, each of the base edges of these branches being connected to each other by a connection. Due to the connecting portions, each of the tip portions of the dilator can move elastically close to and away from each other.

In addition, the dilator may have a positioning member disposed between the pair of branch portions to adjust the position of the pair of branch portions, thereby keeping the distance between the tip portions of the dilator constant during surgery.

Another example of a conventional opening mechanism is disclosed in "MIZUHO" ORPHOPEDIC IMPLANTS & INSTRUMENTS (MIZUHO Co., Ltd., December 2002). For example, the opener that keeps the incision site open to the patient's spine includes a pair of arms connected to each other by a hinge part to be opened and closed, and the incision part is provided at the distal end of the arm. It has a blade that extends and remains open. The arm is integrally provided with a handle for executing the opening and closing operation of the pair of arms. At the ends of the handle are provided rings for inserting the user's fingers, respectively. When the user inserts his finger into the ring to close the handle, the tip of the arm is opened by the arm pivoting about the hinge. In order to keep the tip open, the handle is provided with a lock mechanism that locks the handles against each other in a position proximate to the hinge.

The lock mechanism deflects a plate formed in an arc shape around the hinge and fixed on one handle, a ratchet finger member pivotally provided on the other handle, and the ratt finger member. And a leaf spring provided on the handle to engage the ratchet tooth, wherein the distal end of the ratchet finger member can engage a ratchet tooth formed on the outer periphery of the plate.

In the conventional opening mechanism having the above structure, the arm, the handle, and the ring are removed from the incision when inserting the depth blade into the incision of the patient's body to keep the deep part of the incision open and open. Protrude at an angle. That is, the deeper the blade is inserted into the incision, the steeper the inclination of the arm, handle, and ring, and in severe cases, is substantially perpendicular to the incision. Therefore, there is a problem that the arm, the handle and the ring are likely to interfere with the surgery.

In addition, the conventional opening mechanism manufacturing apparatus has a problem that the configuration is very coarse and not robust, high yield and low productivity.

The present invention is to solve the above problems, to provide an apparatus for producing a disposable surgical opening apparatus that can increase the productivity by easily and quickly manufacturing a disposable surgical opening apparatus.

Hereinafter, the disposable surgical open window apparatus 100 and the disposable surgical open window manufacturing apparatus 1000 according to a preferred embodiment of the present invention will be described in detail.

1 is a perspective view showing a disposable surgical open wound apparatus according to a preferred embodiment of the present invention, Figure 2 is a longitudinal cross-sectional view of Figure 1, Figure 3 is a state diagram of the disposable surgical open wound apparatus according to the present invention.

1 to 3, the disposable surgical opening apparatus 100 according to a preferred embodiment of the present invention has a cylindrical shape, a guide 110 formed of a thin, flexible material, for example, vinyl, which can be wound; An annular ring body 120 of a flexible material which is fixed to the lower end of the guide 110 and is supported inside the surgical incision site C '; And a cylindrical annular winder member 130 fixed to the upper end of the guide 110 in a cylindrical shape, the flexible material having a predetermined height so as to secure a surgical range or a surgical field of view by winding the guide 110 on an outer circumferential surface thereof. Equipped.

The longitudinal cross section of the annular ring body 120 may be circular, and the longitudinal cross section of the winder member 130 may be any one of a “ㅏ” shape (see FIG. 2) or a “l” shape (not shown). Various other modifications can be made.

In the case where the longitudinal section of the winder member 130 has a "ㅏ" shape, the ratio of the thickness t and the height h is preferably 1: 2 to 3. When the ratio of the thickness t and the height h exceeds 1: 3 or more, the winder member 130 may not be bent well, and thus the guide 110 may be formed on the outer circumferential surface of the winder member 130. This is because it is difficult to wind. In addition, the protrusion (P) formed on the side serves to more easily wound by preventing the slip (Slip) when winding the guide 110 on the outer peripheral surface of the winder member (130).

The annular ring body 120 may use a color, for example, white, which is easy to identify even when blood is stained, and the guide 110 uses a matte raw material to prevent glare from illumination. It is desirable to relieve. The guide 110 may have a bellows shape (not shown).

Referring to the use of the disposable surgical open wound apparatus 100 according to the preferred embodiment of the present invention configured as described above are as follows.

An annular ring body 120 is inserted into the surgical incision site C ′ and supports the disposable surgical open device 100. Since the annular ring body 120 is formed of a flexible material such as a rubber, the annular ring body 120 maintains a circularly open state.

In this state, the winder member 130 is bent to wind the guide 110 continuously on the outer circumferential surface of the winder member 130. Since the winder member 130 is formed in a substantially "ㅏ" shape (Hanja aza shape) or "l" shape (date shape), the operator is the guide 110 on the outer peripheral surface of the winder member (130) It can be easily wound to secure the surgical range and the field of view more easily.
