Description

Technical Field

[0001] The invention belongs to the technical field of suturing, and in particular relates to a suturing device for surgical operation and a suturing method thereof. Background Art

[0002] Suturing is to align or reconstruct the passages of tissues and organs that have been cut or broken by trauma, and restore their functions. In other words, suturing is a common surgical procedure in surgery. Suturing is to reconstruct or reposition the passages of tissues and organs that have been cut or broken by trauma, in order to restore their original functions. It is an important surgical step to ensure good healing after surgery. Due to the structural characteristics or functional characteristics of tissues and organs in different parts, different ways and methods are required for suturing. Suturing generally requires the use of suturing tools, or it can be done directly with a straight needle by hand. When suturing certain parts such as tendon or ligament tears, because the tendons or ligaments are attached to the bones, the structural differences in the joints of the bones in different parts and the influence of the shape of the bones, the suturing operation is limited in space. It is inconvenient to suturing with bare hands or needle forceps, and the hands cannot penetrate deeply in some places. The suturing is not firm or not in place, which affects the effect of the operation and is not conducive to postoperative recovery. Moreover, places with smaller spaces are prone to secondary injuries due to accidental contact with instruments. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a suturing device and a suturing method for surgical operations, which effectively avoid the defects in the prior art that the suturing operation is limited by space, making it inconvenient to suturing with bare hands or with needles and forceps, the hands cannot penetrate deeply into some places, the suturing is not firm or is not in place, thus affecting the surgical effect, and is not conducive to postoperative recovery.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1-Figure 4 As shown, a suturing device for surgical operation includes a suturing forceps and a suturing needle 1 arranged at the front of the suturing forceps; the material of the suturing needle 1 is nickel-titanium memory alloy material; the suturing forceps drives the suturing needle 1 to complete the suturing operation. The material of the suturing needle 1 is nickel-titanium memory alloy material as a thermal phase change material, and the suturing forceps drives the suturing needle 1 to complete the suturing operation; effectively avoiding the defects of the prior art that the suturing operation is limited by space, making it inconvenient to suturing with bare hands or needle forceps, the hand cannot penetrate deeply in some places, the suturing is not firm or the suturing is not in place, which affects the surgical effect, is more unfavorable for postoperative recovery, and places with small space are prone to secondary injuries due to accidental contact of instruments.

[0027] The phase change temperature of the suture needle 1 is 40 degrees Celsius to 60 degrees Celsius; the suture needle 1 is in a straight state before being heated for use. After being heated by injecting 40 degrees Celsius to 60 degrees Celsius warm water through the built-in water inlet hole of the needle sleeve 1-2, the front end of the suture needle 1 becomes a surgical suture needle shape. The surgical suture needle is in a semicircular or arc shape. The suture forceps includes an upper clamp arm 2 and a lower clamp arm 3, and the upper clamp arm 2 and the lower clamp arm 3 are hinged by a fulcrum shaft 4. In this way, the upper clamp arm 2 and the lower clamp arm 3 can rotate around the fulcrum shaft 4. The front end of the upper clamp arm is provided with a needle outlet groove, and the rear end of the needle outlet groove is connected to the upper clamp arm through a spring. The rear end of the needle outlet groove is also fastened to the position of the rear end of the upper clamp arm near the clamp ring and the tether buckle 13 arranged on the upper clamp arm through a steel wire rope, and the needle outlet groove is connected to one side of the suture needle; the tunnel for placing the steel wire rope is placed in the upper clamp arm and passes through one side of the fulcrum shaft, which does not affect the opening and closing of the suture forceps. In this way, the needle slot 5 is retracted and released by the pulling force of the steel wire and the pushing force of the spring 6. When the upper clamp arm 2 and the lower clamp arm 3 of the suture forceps are closed, the needle slot 5 is retracted by the steel wire, and at the same time, one side of the suture needle 1 is tightly clamped on the needle slot 5 and the front end of the upper clamp arm 2. The suture needle 1 is externally sleeved with a needle sleeve 1-2.

[0028] The lower clamp arm 3 is provided with a hollow needle hole along its axial direction, and the rear end of the needle hole is connected to a suture 7. The outside of the needle hole is wrapped with a water bag, and the water bag is wrapped to the end of the suture 7. A water inlet is provided at the end of the water bag for injecting warm water of 40 degrees Celsius to 60 degrees Celsius to heat the suture needle 1 to make it undergo a phase change, and the front end of the suture needle 1 becomes a semicircular or arc-shaped surgical suture needle. A push rod 8 is installed at the end of the needle hole, and a paddle 9 is provided at the end of the push rod 8. A card slot 10 is provided on the outer surface of the lower clamp arm 3, and two grooves are provided in the card slot, and the two grooves are groove one and groove two respectively. The groove one and groove two form gear position one and gear position two respectively. When the paddle is engaged, the gear position one pushes part of the suture needle out, and the tail end of the suture needle is still in the needle hole. When the paddle is engaged in the second gear, the suture needle is pushed out of the needle hole. In this way, when the suture forceps are pulled out, the suture needle can pass through the ligament or tendon, and then the suture thread is brought over to push the push rod to push the suture needle out of the needle hole. The suture needle can be prevented from retreating by rotating the paddle to be engaged in the slot. The buckle 11 is located at the ends of the upper clamp arm 2 and the lower clamp arm 3. The buckle 11 is used to lock the upper clamp arm 2 and the lower clamp arm 3 after the upper clamp arm 2 and the lower clamp arm 3 are closed to prevent loosening during the subsequent buckling process. The clamp ring 12 arranged on the upper clamp arm 2 and the lower clamp arm 3 is used for hand-held operation of the suture forceps.

[0029] The suturing method of the surgical suturing device comprises:

[0030] Install the suture needle 1 and its connected suture thread and water bag on the lower clamp arm, extend it into the part to be sutured, open the upper clamp arm 2 and the lower clamp arm 3, clamp the suture part, lock the buckle 11, inject 40 degrees Celsius-60 degrees Celsius warm water through the water inlet of the water bag, heat for 30-120 seconds, push the push rod to push the suture needle out of the lower clamp arm, the front end of the suture needle changes into a semicircular or arc shape due to the phase change force, continue to push the push rod, after the front end of the suture needle passes through the needle outlet groove of the upper clamp arm, continue to tighten the upper clamp arm 2 and the lower clamp arm 3 and lock them with the buckle, operate the suture clamp to continue to complete the suture operation. If you need to suture multiple needles or multiple places, repeat the above suture method.

[0031] Thus, the surgical suturing device and suturing method provided by the present invention are suitable for suturing operations at any part, and are particularly suitable for labor-saving and convenient suturing of parts that are inconvenient to suturing manually during surgery. Suturing operations can be conveniently and quickly performed at various joints. The suturing device can be inserted into narrow parts for suturing operations, which can minimize the size of the surgical approach incision, reduce surgical trauma, and alleviate the pain of patients; the operating steps are simple and easy to understand, and the suturing operation can be mastered with only simple training.
