Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a needle holder for holding and operating a needle for suturing a deep target site during deep surgical operations.

[Prior art and problems]

In conventional suturing needle holders, the handle part and the distal needle holder part are parallel to each other on the same plane. It is difficult to find the deep target area because the hand holding the needle gets in the way. Therefore, in order to suture the target site, it is necessary to cut it larger than necessary. Furthermore, the longer the surgery, the more pain the patient will experience. Furthermore, if the incision is made too large, there are disadvantages such as excessive scarring remaining after the surgery.

[Purpose of this invention]

The present invention has been made to solve the above-mentioned problems and to facilitate the suturing operation of the needle of the needle holder.

[Summary of the invention]

In order to achieve the above object, the present invention does not make the tip needle holder and the handle in front of the needle holder parallel to each other on the same plane. It is shaped like a pistol so that the handle is always positioned below the eye, and the needle holder at the tip can be rotated approximately 90 degrees by operating the handle for suturing.

It is fixed at 13 ₁ and 13 ₂ .

The handle part B is attached to the base of the pipe part C in a pistol shape so as to be located below the axial direction of the intermediate pipe part C, and the upper part of one handle 14 of the handle part B is a plate-shaped part with a wide area. This plate-shaped portion 15
The upper middle part of the other handle 16 is pivotally fixed with a stud 17, and the upper part of the handle 16 holds the shaft 17 and the above-mentioned pulley rotating wires 7 ₁ and 7 ₂ are connected to the upper and lower positions 18 ₁ and 18 ₂ of the shaft 17 . The front end is attached.
Reference numeral 19 denotes a receiving plate for a wire guide attached to the plate-shaped portion 15 in order to facilitate the movement of the wire ₇₁ for rotating one of the pulleys. 20 is the plate-shaped portion 15
Another hemlock-shaped small handle has one end 21 fixed to the shaft, and this small handle has an upper part 22 slightly smaller than the shaft 21.
The front end of the wire 10 that pulls the suture needle holding slide plate 6 is attached to the suture needle holder. The above three wires 7 ₁ , 7 ₂ , and 10 are inserted through the intermediate tube portion C of the needle holder and connected to the tip needle holder.

[Operation of the present invention]

How to use the needle holder of the present invention constructed as described above will be explained.

In the state shown in FIG. 1, the slide plate 6 of the needle holder at the tip of the needle holder is pushed forward by the spring plate 12, and the front end of the slide plate 6 is in pressure contact with the front end of the needle holder 4. To hold the suture needle in the needle holder at the tip of the needle holder, lightly grasp the handle side of the needle holder and press down on the right end of the small handle 20 with your thumb.
is pulled against the spring force of the spring plate 12, causing the slide plate 6 attached to its tip to retreat, and the pressure contact part with the needle holder 4 opens, so the suture needle is inserted into the gap and the small handle is pulled. When the thumb is released from the slide plate 6, the slide plate 6 moves forward due to the restoring force of the spring plate 12 and clamps the suture needle. As shown in Figure 1, one handle 1 of the handle part
6 is in the open state, the wires 7 ₁ and 7 ₂ connected to the handle 16 rotate the pulley 3 of the needle tip holder to a position rotated to the right by about 90 degrees from the state shown in FIG. Therefore, the positions of the needle holder 4 and the slide plate 6 holding the suture needle 23 shown in FIG. 3 are rotated about 90 degrees to the right from the positions shown in FIG.

Lightly grasp the handle side of the needle holder with the suture needle held at its tip as described above, and insert it deep into the target site. At this time, since the handle part is downward in a pistol shape, the hand holding the handle part does not get in the way when inserting the needle holder, and the tip of the needle holder part is always in line of sight, so that the desired suturing can be carried out deep. The site can be easily found and the tip holder can be positioned at the target site. After that, when one handle 16 of the grip part is grasped toward the other handle 14 side, the wire 7
₁ , 7 and ₂ , the pulley 3 at the tip of the needle holder rotates approximately 90 degrees to the left, and as shown in FIG. 3, the suture needle 23 held by the slide plate 6 on the pulley also rotates approximately 90 degrees to the left. and pierce the target area. When the suture needle 23 with the suture thread is inserted into the target site in this way, when the small handle 20 on the handle side is pushed down with the thumb, the slide plate 6 of the tip needle holder moves back and the suture that was being clamped is removed. Since the needle is released, the needle holder can be removed and removed from the suture needle that has been pierced. The subsequent operation is to suture the target area in the same manner as the conventional method.

[Effects of this invention]

As described above, the needle holder of the present invention is formed into a pistol shape such that the needle holder handle is located below the tip needle holder in the line of sight direction, so when inserting the needle holder deep into the body, Since the tip needle holder is not obstructed by the hand holding the handle and is always in line of sight, the tip needle holder can be easily and quickly applied to the deep target site. In addition, since the distal needle holder is mounted on a pulley that is rotated by the operation of the handle on the handle, suturing the deep target site is performed by rotating and piercing the suture needle with the handle on the handle. Suturing operations for deep parts can be easily performed. In addition, the suture needle inserted into the deep target site can be easily removed from the needle holder by operating the handle on the handle side.
The needle holder of the present invention has excellent features as a needle holder for suturing deep parts.
