Description

Surgical instrument for suturing

technical field

The utility model relates to a surgical instrument for suturing.

Background technique

Suture (suture) is to close or reconstruct the channel of the tissue or organ that has been cut or traumatized, and restore its function. It is the basic condition to ensure good healing, and it is also one of the important basic surgical techniques.

In recent years, minimally invasive surgery has become more and more popular. As the name suggests, it refers to tiny wounds and wounds, which are the characteristics of modern medical surgical treatment. Compared with traditional surgery, minimally invasive surgery has four major characteristics: small incision, small trauma, quick recovery, and less pain. Minimally invasive surgery is a medical revolution brought about by high technology. However, minimally invasive surgery is indeed a difficult problem. Small wounds require little space for suturing operations. At present, endoscopes are generally used for surgery, and suturing is performed through an observation screen. Since the surgical site cannot be directly seen, the speed of suture knotting is inconvenient, and the suture is not firm, which is likely to cause poor wound suture results.

Contents of the invention

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the utility model more clear, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described The embodiments are some embodiments of the present utility model, but not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in FIGS. 1-4 , a surgical instrument of the present invention includes a main base body 1 , a hollow tube body 2 , a fixing thread 5 , a tension thread 4 , and a suture thread 6 .

Wherein, specifically, the main base body 1 is set as a plate-shaped body, which is set as a rectangle in this embodiment, and a through hole 10 is provided in the center of the lower part of the main base body 1, and a shielding piece 3 arranged perpendicularly to the main base body 1 is provided on one side thereof. In this embodiment, the shielding piece 3 is arranged in an L shape, and a fixing hole 11 is provided on the upper side of the main base 1 adjacent to the shielding piece 3 .

The hollow tube body 2 is arranged on the through hole 10 of the main base body 1, and extends and protrudes toward the inner side of the main base body 1, and the surface of the hollow tube body 2 is set as a smooth surface.

One end of the fixing wire 5 is arranged in the fixing hole 11 , and the other end is arranged outside the through hole 10 .

The tension wire 4 is set as a flexible body, one end of which is connected to the fixed wire 5 and is arranged in the fixing hole 11 of the main base body 1, and the other end can be bent inside the main base body 1 to form a tension part 41 to hook the suture 6.

The suture 6 is set to form two loops of sliding knots 61 on the hollow body 2 with a smooth surface, one end of the suture 6 is provided with a suture needle 60, and the other end is hooked to the tensioning part 41 of the tension line 4 and passed through the sleeve Extend into the hollow tube body 2 and extend to the outside of the main base body 1. The suture line 6 is formed between the tensioning part 41 formed by bending the tension line 4 and the hollow tube body 2 on the inside of the main base body 1 for the suture needle 60 to wear. The slip knot sleeve 62, the suture 6 of the tightening part 41 is provided with a knot identification part 64 near the snare of the slip knot 61 of two circles.

As shown in Figures 5A-5F, when a surgical instrument of the present invention is used, first place the tail end of the suture 6 with the suture needle 60 on the hollow tube body 2 near the main seat body 1, and set one or two loops of sliding knots. 61 and formed into a triangular sliding knot sleeve 62, which is hooked by the tension part 41 formed by the tension line 4 adjacent to the fixing hole 11, and then the other end of the suture line 6 passes through the hollow tube body 2 and is located in the main body. The fixing thread 5 at the outer side of the seat body 1 is knotted, so that the suture thread 6 is unidirectionally fixed to the through hole 10 of the hollow body 2 outside the main seat body 1, so that it is convenient to install the hollow body 2 after the operation. The main base body 1 is taken, and when the suture line 6 is operated and sutured, the surgical forceps 7 clamp the suture needle 60 to suture the wound 8, and when the thread is drawn, another surgical forceps 7 is used to clamp the other end of the suture line 6 and pull the other end of the suture line together ( As shown in Fig. 5A); when needing to tie a knot, another surgical forceps 7 can be grasped the main base body 1 and make its hollow body 2 turn to point to the operator, and the sewing needle 60 is convenient to slip through the sleeve 62 for operation. In the utility model, since the side of the main base body 1 is provided with an L-shaped protective plate 3, only the sliding knot sleeve 62 is exposed at the part of the suture needle 60 through the sheath, so that the suture needle 60 can be completely prevented and avoided from being worn in the wrong position and knotted. Failed, clamped the surgical forceps 7 holding the suture needle 60 and passed it through the triangular sliding knot sleeve 62 formed by the suture 6, and pulled it outward in a U-shaped turn (as shown in Figure 5B); The new type is provided with a knot marking part 64 (as shown in FIG. 6A ) that can be clearly identified by the naked eye at the initial disposition of the snare of the two-circle slip knot 61. The arrow in the figure is the knot mark 64, which is stitched together. After the needle 60 and the suture thread 6 pass through the sliding knot sleeve 62, another surgical forceps 7 can be grasped at the tail end of the main base body 1 and turned 90 degrees at this time, so that the hollow pipe body 2 turns to the vertical wound 8 and stops still. Then the surgical forceps 7 holding the suturing needle 60 are clamped and grasped to slowly pull the suture 6 outward (as shown in Figure 5C), so that the suture 6 originally hooked on the tightening part 41 falls off, (as shown in Figure 5D ), and then continue to pull outward until the required suture tension stops (as shown in Figure 5E); at this time, the clamper 7 that clamps and grasps the suture needle 60 is stationary, and the clamping grasps the suture thread 6 The surgical forceps 7 at the tail end can be quickly and reversely pulled outward to make the two loops of sliding knots 61 originally arranged on the hollow body 2 fall off, and automatically become reliable multiple fixed knots 63 (as shown in Figure 5F), and the knotting is completed The rear knot marking 64 moves and is located more than 5 mm outside the multiple fixed knot 63. If the knot marking part 64 is near the completion of the two-turn slip knot 61, or is embedded in the two-turn slip knot 61, it means that the knot has failed, that is, Two turns of sliding knot 61 failed to turn into multiple fixed knot 63 (as shown in FIG. 6C ).

The utility model is an instrument used for surgical operation. Two semi-knotted slip knots are preliminarily arranged on the small tube. When the surgical suturing of the wound is completed, the two slip knots fall off from the small tube and automatically and rapidly transform into a reliable and safe multiple knot. The knot is fixed, and the success of the knot is displayed through the knot label, which improves the knotting speed, the suture effect is good, and the successful knotting of the operation can be directly displayed, which is convenient for doctors to operate.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than limiting it; although the utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: description It is still possible to modify the technical solutions described in the foregoing embodiments, or to perform equivalent replacements for some of the technical features, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technology of the various embodiments of the present invention. The spirit and scope of the programme.
