Description

Technical Field

[0001] The present invention relates to the technical field of Achilles tendon suturing, and in particular to a three-dimensional Achilles tendon minimally invasive suturing auxiliary device. Background Art

[0002] The Achilles tendon is a tendinous structure that transitions from the lower end of the belly of the triceps surae, namely the gastrocnemius and soleus muscles, and ends at the calcaneal tuberosity. It is one of the thickest and largest tendons in the human body and is of great significance for the body's walking, standing and maintaining balance. The high-risk groups for Achilles tendon rupture are student athletes and actors. In recent years, with the widespread development of mass sports and the continuous improvement of sports levels, the incidence of Achilles tendon rupture has increased year by year. Except for a few open Achilles tendon ruptures caused by in situ trauma to the Achilles tendon, most Achilles tendon ruptures are caused by indirect external forces. Some patients with Achilles tendon ruptures have chronic diseases related to the Achilles tendon before the Achilles tendon rupture occurs.

[0003] After the Achilles tendon is ruptured, it needs to be sutured in time. The existing suture methods are mostly parallel suture methods, which have poor cutting resistance. In addition, the existing three-dimensional suture method requires a larger incision during suture, which is easy to increase the damage to the patient.

[0004] Therefore, a three-dimensional Achilles tendon minimally invasive suture auxiliary device is proposed. Summary of the invention

When the Achilles tendon is placed between the third auxiliary claw 5 and the fourth auxiliary claw 6, the fixing clamp passes through the holding hole 10 and extends from the V-shaped groove 7 to clamp and fix the Achilles tendon, which is convenient for three-dimensional suturing of the Achilles tendon and can reduce the manual clamping and fixation of medical staff.

[0066] In summary, in the present invention, under the rotation of the first ball head 15 and the second ball head 16, and the up-and-down sliding connection of the first puncture needle 8 and the second puncture needle 9 in the first puncture groove 11 and the second puncture groove 12, the three-dimensional suture routing structure of the first puncture needle 8 and the second puncture needle 9 for the ruptured Achilles tendon can be realized, so that its anti-cutting ability is enhanced;

[0067] In the present invention, when the user needs to use three-dimensional cross suturing, the first puncture needle 8 and the second puncture needle 9 are slightly pulled out respectively, so that one end of the first puncture needle 8 and one end of the second puncture needle 9 are separated from the first ball head 15 and the second ball head 16, and the first puncture needle 8 and the second puncture needle 9 are slid below the first puncture groove 11 and the second puncture groove 12, and one end of the first puncture needle 8 is inserted into the first eccentric hole 17, and one end of the second puncture needle 9 is inserted into the second eccentric hole 18, which can be deflected during the puncture process of the ruptured Achilles tendon, so as to adjust the position of the suture back, and form a three-dimensional structure of the side again, thereby forming a three-dimensional three-dimensional cross suturing;

[0068] In the present invention, the puncture in the auxiliary device is a minimally invasive puncture, which can effectively reduce the area of ​​the wound and avoid damage to nerves and blood vessels;

[0069] In the present invention, the first scale lines 23 and the second scale lines 24 are arranged on the front and rear sides of the outer walls of the first auxiliary claw 3 and the second auxiliary claw 4. The user can facilitate the positioning and connection of the puncture under the action of the first scale lines 23 and the second scale lines 24, so that the first puncture needle 8 and the second puncture needle 9 can be accurately adjusted and limited by angle markings during three-dimensional suturing;

[0070] In the present invention, when the Achilles tendon is placed between the third auxiliary claw 5 and the fourth auxiliary claw 6, the fixing clamp passes through the holding hole 10 and extends from the V-shaped groove 7 to clamp and fix the Achilles tendon, which is convenient for three-dimensional suturing of the Achilles tendon and can reduce manual clamping and fixation by medical staff.

[0071] Parts not involved in the present invention are the same as the prior art or can be implemented by the prior art. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
