Description

Technical Field

[0001] The invention relates to the technical field of suture needles, in particular to a special suture thread guiding device for cervical surgery. Background Art

[0002] With the advancement of medical technology, more and more cervical surgeries such as cervical conization and cervical repair are widely used in clinical practice to treat cervical lesions, reduce the risk of cervical cancer, and deal with related problems after delivery. Traditional suturing methods often cannot meet the special needs of cervical surgery due to their design limitations. The characteristics of cervical tissue are complex and soft, and the requirements for suturing materials and suturing tools are high. First, cervical tissue is rich in blood vessels, and bleeding needs to be accurately controlled during surgery to avoid damage to surrounding tissues. Secondly, the suture of the cervical area needs to have good tension and durability to ensure good postoperative healing and avoid scar formation. In order to solve these problems, special suturing needles for cervical surgery came into being. The design of this needle fully considers the anatomical structure and physiological characteristics of the cervix, and usually adopts a slender and curved needle body design to facilitate operation in a narrow surgical field of view. Its tip is specially treated to easily penetrate the soft cervical tissue while reducing damage to surrounding tissues. The material of the suture needle is also carefully selected, mostly stainless steel or polymers with good biocompatibility to ensure safety and durability in the body.

[0003] However, the existing technology still has major deficiencies, such as:

[0004] In the prior art, cervical surgeries are all performed using suture needles to suture the surgical site. However, the suture needles are often too thin and soft, so they are prone to bending during use. As a result, the suture needles often cause problems during the suture process, causing medical staff to waste energy and being very inconvenient. Summary of the invention

[0005] The object of the present invention is to provide a suture guide device specifically for cervical surgery to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A suture thread guiding device for cervical surgery, comprising a suture needle body, wherein two ends of the suture needle body are respectively provided with a needle tip and a needle tail, and the needle tail is connected with a suture thread;

[0008] The radian of the suture needle body is π radians, and the diameter of the suture needle body is not less than 9 mm;

[0009] The needle tip is movably connected to the suture needle body, a threaded hole is provided on the suture needle body, and a threaded rod corresponding to the threaded hole is provided on the needle tip;

[0010] The needle tip is coated with a reinforcing coating, and the suture needle body is provided with a plurality of reinforcing coatings.

[0011] Preferably, the straight-line distance from the needle tip to the needle tail is 17 mm, and the length of the suture is not less than 90 cm.

[0012] Preferably, the reinforcement coating is an aluminum oxide coating, and the coating thickness is not less than 1 mm.

[0013] Preferably, the needle tip, suture needle body and needle tail are round needles.

[0014] Preferably, the suture needle body, needle tip and needle tail are all made of high-strength alloy.

[0015] Preferably, the high-strength alloy is a stainless steel alloy.

[0016] Preferably, open grooves are provided on both sides of the suture needle body, the curvature of the open grooves is the same as the curvature of the suture needle body, and reinforcing ribs are provided inside the open grooves.

[0017] Preferably, when the reinforcing rib is placed inside the open groove, the outer surface of the reinforcing rib coincides with the surface of the suture needle body.

[0018] Preferably, the length of the reinforcing rib is not less than half the length of the suture needle body.

[0019] Preferably, the reinforcing ribs are made of titanium alloy, and the sutures are absorbable sutures.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The threaded rod and the threaded hole are arranged so that the needle tip and the suture needle body are divided into two parts. Once the needle tip is deformed and bent during use, the needle tip can be replaced separately, which can save a certain amount of use cost;

[0022] 2. Aluminum oxide coating is applied on the tip of the needle to ensure the strength of the tip of the needle and make the outer surface of the tip of the needle smoother. During the suturing process, the friction between the skin and the flesh is reduced, ensuring smooth suturing;

[0023] 3. By setting an open groove in the suture needle body and setting reinforcing ribs inside the open groove, on the one hand, the strength of the suture needle body is guaranteed, and at the same time, the use of the reinforcing ribs will not cause bulges on the surface of the suture needle, thereby affecting the suture effect.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-4 , the present invention provides a technical solution:

[0031] A suture thread guiding device for cervical surgery, comprising a suture needle body 1, wherein two ends of the suture needle body 1 are respectively provided with a needle tip 101 and a needle tail end 102, and the needle tail end 102 is connected with a suture thread 2, and the suture thread 2 is an absorbable suture thread;

[0032] The suture needle body 1 in this embodiment is a part in the middle of the entire suture needle, and the tail end of the suture needle body 1 is the needle tail end 102. The suture needle body 1 and the needle tip 101 are movably connected. The threaded hole 3 and the threaded rod 4 are arranged so that the suture needle body 1 and the needle tip 101 can be disassembled and connected. The end surface of the threaded rod 4 provided with the needle tip 101 is the same size as the end surface of the threaded hole 3 provided with the suture needle body 1. When the needle tip 101 is screwed onto the suture needle body 1 through the threaded rod 4, the connection is overlapped and no deviation occurs. Such an arrangement ensures the streamline of the entire suture needle and also ensures the smoothness during use.

[0033] The radian of the suture needle body 1 is π radians, and the diameter of the suture needle body 1 is not less than 9 mm;

[0034] The curvature of the suture needle body 1 in this embodiment is the same as the curvature of the overall suture needle. At the same time, the diameter of the suture needle body 1 in this embodiment is not less than 9 mm, which ensures the strength of the suture needle body 1.

[0035] The needle tip 101 is movably connected to the suture needle body 1. The suture needle body 1 is provided with a threaded hole 3. The needle tip 101 is provided with a threaded rod 4 corresponding to the threaded hole 3.

[0036] In this embodiment, the suture needle body 1 and the needle tip 101 are set as two parts. During use, if the needle tip 101 is bent, the needle tip 101 can be replaced in time. At the same time, the same suture needle body 1 can also adapt to a needle tip 101 with higher strength. Because the thickness of the entire suture needle is continuously reduced as the needle tip 101 is higher, the strength will also decrease accordingly. In this way, the strength of the needle tip 101 is generally reduced, so it is set to be replaceable. At the same time, in order to ensure that the needle tip 101 can puncture better, a reinforcing coating is applied to the needle tip 101 to enhance the strength of the needle tip 101, rather than simply increasing the strength of the suture needle by increasing the thickness.

[0037] The needle tip 101 is coated with a reinforcing coating, and the suture needle body 1 is provided with a plurality of reinforcing coatings.

[0038] The straight-line distance from the needle tip 101 to the needle tail 102 is 17 mm, and the length of the suture thread 2 is not less than 90 cm.

[0039] The strengthening coating is an aluminum oxide coating with a coating thickness of not less than 1 mm;

[0040] The reinforcing coating in this embodiment is an aluminum oxide coating, and the thickness of the aluminum oxide coating shall not be less than 1 mm. This not only increases the strength of the needle tip 101, but also ensures that the needle tip 101 will not be too thick, thereby not affecting the puncture effect of the needle tip 101.

[0041] The needle tip 101, the suture needle body 1 and the needle tail end 102 are round needles.

[0042] In the technical field, there are generally two types of suture needles, one is a round needle and the other is an angle needle. This can be selected according to the sutured part and other requirements. The suture needle body 1 and the needle tip 101 in this embodiment are round needles.

[0043] The suture needle body 1 , the needle tip 101 and the needle tail 102 are all made of a high-strength alloy, and the high-strength alloy is a stainless steel alloy.

[0044] The suture needle body 1, the needle tip 101 and the needle tail 102 in this embodiment are all made of high-strength alloy, which can ensure the strength of the entire suture needle. The high-strength alloy in this embodiment is preferably a stainless steel alloy.

[0045] Open grooves 5 are provided on both sides of the suture needle body 1. The curvature of the opening grooves 5 is the same as that of the suture needle body 1. Reinforcing ribs 6 are provided inside the opening grooves 5. When the reinforcing ribs 6 are placed inside the opening grooves 5, the outer surface of the reinforcing ribs 6 coincides with the surface of the suture needle body 1. The length of the reinforcing ribs 6 is not less than half the length of the suture needle body 1. The reinforcing ribs 6 are made of titanium alloy.

[0046] In the present embodiment, open grooves 5 are provided on both sides of the suture needle body 1, and reinforcing ribs 6 are arranged inside the open grooves 5, which can ensure that the reinforcing ribs 6 do not need to be arranged on the outer surface of the suture needle body 1, so that the thickness of the suture needle body 1 will not be increased, and the strength of the suture needle body 1 can be increased. The reinforcing ribs 6 in the present embodiment can completely cover the open grooves 5, and when the reinforcing ribs 6 are fixed inside the open grooves 5, the outer surface of the reinforcing ribs 6 and the suture needle body 1 form a whole, which can ensure the smoothness of the subsequent use of the suture needle. The reinforcing ribs 6 are made of titanium alloy, which can further ensure the strength of the suture needle body 1, and the length of the reinforcing ribs 6 is not less than half of the suture needle body 1. Such a setting can further ensure the strengthening effect of the reinforcing ribs 6

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
