Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a thread guide for suturing ruptured Achilles tendon. Background Art

[0002] The Achilles tendon is a tendinous structure that extends 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. After rupture, the open incision surgery requires large incision and severe damage. Minimally invasive surgery has become a hot topic in recent years, but it has both advantages and disadvantages.

[0003] Common minimally invasive suture methods for the Achilles tendon include: the Ma&Griffith method, which makes six small incisions around the Achilles tendon and passes the sutures through the small incisions; the "Achilles tendon dragon" method, which makes a transverse incision at the stump of the Achilles tendon and uses a special threader to insert the distal and proximal ends of the Achilles tendon to guide the sutures through the Achilles tendon. Finally, the sutures are pulled into the incision at the stump and knotted to secure them. Existing minimally invasive surgical methods are cumbersome, and there are still more or longer skin incisions during the operation, which affects the postoperative healing effect and the aesthetic appearance of the wound healing. In addition, there is a risk of adhesion between the Ma&Griffith sutures and the tissues around the Achilles tendon, and the incidence of sural nerve injury is also high. Utility Model Content

[0004] The utility model aims to provide a suture thread passing device for Achilles tendon rupture with three special channels.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A suture thread passer for Achilles tendon rupture comprises a main rod and a head, wherein the two main rods are connected and installed together through a mounting portion, and the two ends of the main rods are respectively installed with a holding portion and a head; a channel assembly is arranged at one end of the two main rods close to the head, and the channel assembly is used to simultaneously complete three sutures crossing the Achilles tendon; and a limiting piece is installed at one end of the two main rods close to the holding portion.

[0007] It can be seen that the operator places one end of the main rod mounting head at the surgical incision, uses the suture to pass through the distal and proximal ends of the Achilles tendon through the skin surface to guide the suture through the Achilles tendon, and uses the three different channels on the channel component to pull the Achilles tendon tissue to a fixed position and then tie a knot to fix it. By using the channel component to insert three sutures at the same time to cross the Achilles tendon, it can not only avoid repeated damage to the tissues around the Achilles tendon but also reduce the number or length of skin incisions, thereby improving the healing effect after surgery.

[0008] Furthermore, the channel assembly includes a first channel opening, a second channel opening and a third channel opening; the first channel opening, the second channel opening and the third channel opening are sequentially installed at the end of the main rod, the first channel opening is connected to the end of the main rod, and the third channel opening is connected to the head; the first channel opening, the second channel opening and the third channel opening are all in arc shape, and the first channel opening, the second channel opening and the third channel opening are respectively spaced two centimeters apart.

[0009] By using the first channel opening, the second channel opening and the third channel opening for one insertion, three sutures can be simultaneously placed across the Achilles tendon, thereby avoiding damage to surrounding tissues caused by repeated insertions and adhesions caused by stratification of soft tissues in the channel.

[0010] Furthermore, the inner side surfaces of the first channel opening, the second channel opening and the third channel opening are all threaded.

[0011] The thread pattern can not only better grip the Achilles tendon component and pull it to the normal position of the epidermis, but also effectively avoid the sural nerve, preventing the sural nerve from secondary injury, and effectively improving the protection of the sural nerve.

[0012] Furthermore, the head includes two arcuate edges and two pointed edges, the arcuate edges extend from both sides of one end of the main rod close to the channel assembly in a direction gradually away from the central axis of the main rod; the pointed edges extend from the arcuate edges in a direction gradually approaching the central axis of the main rod until the two pointed edges are connected at the top, and the arcuate edges and the pointed edges are connected.

[0013] By using curved edges and pointed edges, the resistance of the heel to puncture during surgery can be reduced, the efficiency of puncture can be improved, the number of repeated punctures can be reduced, and the damage to soft tissue during puncture can be reduced.

[0014] Furthermore, the main rod is in the shape of an arc rod as a whole, and the cross section of the main rod is circular.

[0015] The arc-shaped main rod can be used to match the curvature of the human tissue under the Achilles tendon, avoiding secondary damage to the human tissue during the operation, which is not conducive to the patient's recovery. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-3 As shown, a suture thread passer for Achilles tendon rupture includes a main rod 1 and a head 4. The two main rods 1 are connected and installed together through a mounting portion 11, and the two ends of the main rods 1 are respectively installed with a gripping portion 2 and a head 4; a channel assembly 3 is provided at one end of the two main rods 1 close to the head 4, and the channel assembly 3 is used to simultaneously complete three sutures crossing the Achilles tendon; a limiting member 5 is installed at one end of the two main rods 1 close to the gripping portion 2.

[0022] During the operation, the operator holds the handle 2 to operate the main rod 1 to place one end of the main rod 1 with the head 4 installed at the surgical incision, and uses the head 4 to penetrate to the side of the Achilles tendon, and uses the suture to pass through the distal and proximal ends of the Achilles tendon through the skin surface to guide the suture through the Achilles tendon, and uses the three different channels on the channel assembly 3 to pull the Achilles tendon tissue to a fixed position and then tie a knot to fix it, so as to achieve the goal of inserting three sutures at a time to cross the Achilles tendon and avoid repeated damage to the tissues around the Achilles tendon.

[0023] Specifically, the channel assembly 3 includes a first channel opening 31, a second channel opening 32, and a third channel opening 33; the first channel opening 31, the second channel opening 32, and the third channel opening 33 are sequentially installed at the end of the main rod 1, the first channel opening 31 is connected to the end of the main rod 1, and the third channel opening 33 is connected to the head 4; the first channel opening 31, the second channel opening 32, and the third channel opening 33 are all in an arc shape, and there is a two-centimeter interval between the first channel opening 31, the second channel opening 32, and the third channel opening 33. During the operation, after the sutures are inserted into the Achilles tendon through the first channel opening 31, the second channel opening 32, and the third channel opening 33, the Achilles tendon assembly is pulled to the normal position of the epidermis with the sutures and knotted and fixed. The three sutures are simultaneously inserted through the Achilles tendon at one time, which can avoid the damage to the surrounding tissues caused by repeated insertions and the adhesion caused by the stratification of the soft tissues in the channel.

[0024] Specifically, the inner side surfaces of the first channel opening 31, the second channel opening 32, and the third channel opening 33 are all threaded. During the operation, when three sutures are inserted through the first channel opening 31, the second channel opening 32, and the third channel opening 33 and then cross the Achilles tendon, the threaded pattern can not only better hold the Achilles tendon component and pull it to a normal position on the epidermis, but also effectively avoid the sural nerve, prevent the sural nerve from being damaged again, and effectively improve the protection effect on the sural nerve.

[0025] Specifically, the head 4 includes two arcuate edges 41 and two pointed edges 42. The arcuate edges 41 extend from both sides of one end of the main rod 1 close to the channel assembly 3 in a direction gradually away from the central axis of the main rod 1; the pointed edge 42 extends from the arcuate edge 41 in a direction gradually approaching the central axis of the main rod 1 until the two pointed edges 42 are connected at the top, and the arcuate edge 41 and the pointed edge 42 are connected. By using the arcuate edge 41 and the pointed edge 42, the resistance of the heel to puncture during surgery can be reduced, the efficiency of puncture can be improved, the number of repeated punctures can be reduced, and the damage to soft tissue during puncture can be reduced.

[0026] Specifically, the main rod 1 is in the shape of an arc rod, and the cross section of the main rod 1 is circular. The arc rod-shaped main rod 1 can be used to match the curvature of human tissue under the Achilles tendon, avoiding secondary damage to human tissue during surgery, which is not conducive to patient recovery.
