Achilles tendon minimally-invasive suture instrument set

Abstract

The invention relates to an achilles tendon minimally-invasive suture instrument set which comprises two achilles tendon minimally-invasive threading devices and two minimally-invasive suture needles. Each achilles tendon minimally-invasive threading device comprises a handle, a connecting rod and a threading hole; each handle is in a flat shape and has the length of 90 mm and the thickness of 6 mm, the surfaces of the handles are subjected to drawing, polishing and skid preventing treatment, and the surface of each handle is provided with a spherical groove with the diameter of 10 mm, so that a user conveniently holds the handle in a pressing mode with the thrumb, and one end of each handle is connected with the corresponding connecting rod; each connecting rod has the total length of 130 mm and the diameter of 3 mm, the fracture surface of each connecting rod is in a circular shape, each connecting rod is bent at the position 30 mm away from the corresponding handle in 170 degrees, and the other end of each connecting rod is connected with the corresponding threading hole; the threading holes are in a long circular shape, the plane where the threading holes are located keeps consistent with the plane where the handles are located, the thickness of the side face of each threading hole is 3 mm, the front-view hole wall thickness is 1 mm, the external length of the threading holes is 12 mm, the external width of the threading holes is 6 mm, the internal length of the threading holes is 9 mm, the internal width of the threading holes is 4 mm, the two ends of each threading hole are provided with two point-like protrusions respectively, the point-like protrusions face the bending direction of the connecting rods, and each point-like protrusion has the diameter of 1.5 mm and the height of 1.5 mm. Straight needles are adopted as the minimally-invasive suture needles, and absorbable suture lines are arranged at the needle tails. According to the achilles tendon minimally-invasive suture instrument set, surgical operation can be simplified, blood circulation of the achilles tendon tissue is protected, and the good suture effect is guaranteed.

Description

technical field [0001] The invention relates to a medical operation instrument, in particular to a threader and a suture needle used in the minimally invasive operation of Achilles tendon rupture. Background technique [0002] Achilles tendon rupture is usually seen in sports injuries, such as violent contraction of the calf triceps or strong dorsiflexion of the ankle joint may cause Achilles tendon rupture. The site of Achilles tendon rupture is usually 4 to 6 cm above the Achilles tendon insertion. After the Achilles tendon rupture, the active plantar flexion of the affected foot is limited, and it is impossible to do kicking exercises, which greatly affects the normal life and exercise ability of the patient. The traditional method of treating Achilles tendon rupture requires extensive incision of the skin behind the Achilles tendon, peeling off the synovial tissue around the Achilles tendon, exposing the Achilles tendon stump and the distal and proximal Achilles tendon t...
