FIG. 1 is a block diagram of a shuttle needle in an embodiment of the present invention.

Detailed Description

The present invention will be described in further detail with reference to fig. 1.

A spindle needle for minimally invasive repair of ruptured achilles tendon comprises a spindle needle main body 1, wherein one end of the main body 1 is provided with a conical tip part 2, a transition section 3 is arranged between the tip part 2 and the main body 1, and the longitudinal section of the transition section 3 is circular; the other end of the main body 1 is provided with an extension part 4, and the free end of the extension part 4

A buffer mechanism 5 with an obtuse angle structure is arranged; the middle part of the main body 1 is provided with a through hole 6, and the cross section of the through hole 6 is in an oval shape with two narrow ends and a wide middle part.

The through hole 6 and the end part of the tip part 2 form a preset distance; the thinner end 2.1 of the tip part 2 is set to be planar, the thinner end 2.1 is close to the through hole 6, and a plurality of salient points are arranged at the end part of the thinner end 2.1.

The transition section 3 is formed in an arc shape so that an included angle of an obtuse angle is formed between the tip portion 2 and the main body 1.

The outer diameter of the transition section 3 decreases gradually in the direction from the main body 1 to the tip end 2.

The buffer mechanism 5 includes a disk-shaped buffer member which is expanded outward from the end of the main body 1 along the periphery, and the end of the buffer member is provided with a tip.

The application based on the fusiform needle comprises the step of repairing the achilles tendon fracture through the fusiform needle in a minimally invasive mode.

In the process of repairing by using the shuttle needle, the following processes are included:

after satisfactory anesthesia, the balloon tourniquet is used in prone position. Palpating the tendon rupture site, cutting a 3-4 cm long transverse skin incision, and pulling out the proximal tendon rupture end with tissue forceps. The No. 2 Aixibang suture is passed through the needle hole of the shuttle-shaped needle, the needle is inserted from one side of the tendon near the broken end at an angle of 45 degrees with the long axis of the tendon, the front needle penetrates the skin, the finger senses the length of the needle to be drawn out by touch until the rear needle point is about to withdraw from the achilles tendon, the needle withdrawal is stopped, the suture length reserved for the broken end suture is adjusted, the angle of the needle for sewing the skin is adjusted to be vertical to the direction of the front needle, the needle point outside the skin is changed into the rear needle point, the rear needle point remained in the tissue is changed into the front needle point, the needle is continuously inserted into the skin to penetrate the skin until the rear needle point is about to leave the achilles tendon, the needle outlet is stopped, the suture exposed outside the skin along with the shuttle-shaped needle is drawn, the suture is tensioned, the angle of the needle is adjusted outside the skin to be vertical to the direction of the front needle, the previous needle is continuously repeated, the previous steps are carried out, the suture is crossed and penetrates out from the opposite side of the broken end of the achilles tendon, the suture is cut off, the shuttle-shaped needle, thus leaving 4 sutures at the proximal end. The distal severed end of the Achilles tendon was similarly manipulated, leaving 4 sutures in the distal severed end. The metatarsus bends the ankle joint to ensure that the broken ends of the Achilles tendon are involuted, and 4 corresponding sutures at the two broken ends of the Achilles tendon are respectively knotted to complete the suture of the Achilles tendon. Loosen the tourniquet, stop bleeding and wash the wound surface. 3-0 the peritendinous membrane and subcutaneous layer can be sutured with absorbable suture. Suturing skin incision with No. 1 silk thread, wrapping with sterile adjuvant, and fixing with plantar flexion short leg plaster support.

Through adopting the device that this application provided, following technological effect has been reached:

compared with other minimally invasive suture methods for treating the achilles tendon, the method can complete the achilles tendon suture technology without completely separating a suture needle from the achilles tendon, and the suture needle uses the same needle path in the operation process, so that the phenomenon that the suture needle enters after the suture needle is removed is avoided. If the needle is inserted after the needle exits, the needle cannot be ensured to be inserted completely along the same needle path when the needle exits, and the tissue outside the Achilles tendon, particularly the sural nerve, cannot be sutured or cut by the suture. According to the method, a needle does not need to be discharged completely, the suture needle always occupies the same needle channel, and common complication of sural nerve injury in the operation is thoroughly avoided;

minimally invasive, a transverse incision with the length of about 3cm is cut in the operation, a plurality of needle holes are formed, the needle holes do not need to be sutured, and compared with other longitudinal incision minimally invasive suturing technologies, the minimally invasive suture device is small in incision, few in incision and more minimally invasive;

The present invention and its embodiments have been described above, and the description is not intended to be limiting, and the drawings are only one embodiment of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the spirit and scope of the invention as defined by the appended claims.
