Description

Technical Field

[0001] The utility model relates to the technical field of Achilles tendon suturing, in particular to an Achilles tendon suturing device. Background Art

[0002] Achilles tendon suture is a surgical method for repairing Achilles tendon rupture. For partial Achilles tendon rupture, direct suture can be used; if the Achilles tendon has a cauda equina tear, it is necessary to clean the hematoma at the end of the stump, and overlap and suture the Achilles tendon parts closer and farther from the stump. Multi-point suture fixation can maintain the continuity and integrity of the Achilles tendon. Plaster fixation is required after surgery, and appropriate functional exercises are performed during the fixation process to gradually restore the normal function of the triceps surae.

[0003] When suturing the Achilles tendon, an Achilles tendon suture device is required for assistance. The existing Achilles tendon suture device is a straight arm structure, and generally includes two outer straight arms and two inner straight arms. There are two problems in operation. For example, in the patent with the national authorized patent announcement number CN103417252B, multiple straight arms occupy a large space, reducing the doctor's operating space; the straight arm structure is not easy to fit and insert into the Achilles tendon position, which is inconvenient to operate. Utility Model Content

[0004] In view of this, the utility model provides an Achilles tendon suture device, which is used to solve the problem that the existing Achilles tendon suture devices in the prior art are inconvenient to operate.

[0005] An Achilles tendon suture device comprises two relatively arranged clamping blocks with adjustable spacing and a threading needle. One side of the two clamping blocks is respectively provided with mutually parallel clamping arms, the clamping arms are arranged in an "S"-shaped structure, and a threading hole with an internal thread is opened on the clamping arms; the threading needle has an external threaded portion, and the threading needle is inserted into the threading hole and is threadedly connected to the threading hole.

[0006] Preferably, a handle bolt is rotatably installed on one of the above-mentioned clamping blocks, and the handle bolt passes through the clamping block and is threadedly connected to a threaded hole opened on the other clamping block; a sliding rod is fixedly connected to the side of one of the clamping blocks, and the sliding rod is slidably inserted into the sliding hole opened on the side of the other clamping block.

[0007] Preferably, both ends of the needle hole are provided with chamfered openings, and a limiting convex ring which can be inserted into the chamfered opening is provided on one end surface of the external threaded portion of the needle.

[0008] Preferably, a first indexing hole and a second indexing hole are formed at one end of the clamping arm.

[0009] Preferably, the clamp block and the clamp arm are configured as an integrated medical stainless steel structure or titanium alloy structure.

[0010] Implementing the embodiments of the present utility model will have the following beneficial effects:

[0011] The Achilles tendon suture device described above reduces two outer straight arms compared to the prior art, and a needle hole with an internal thread is provided on the clamp arm, and the needle is directly threadedly fixed on the clamp arm, which can also be firmly positioned to meet the use requirements; and the influence of the outer straight arms is reduced, which is convenient for doctors to operate;

[0012] At the same time, the traditional straight arm structure design has been changed, and the clamp arm is set to an "S" shape structure, which fits the Achilles tendon better, making it easy to accurately insert the clamp arm into the positions on both sides of the Achilles tendon and convenient to operate.
