Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to a microsurgical needle holder. Background Art

[0002] Most of the existing microsurgical needle holders are not equipped with blades. When cutting the thread, it is necessary to replace them with scissors, which is very inconvenient to operate; some install the blade in the area of the handheld part. When cutting the thread, it is necessary to use another pair of pliers to pass the needle and thread through the area of the handheld part and then cut the thread, and the operation is also very inconvenient. At the same time, the existing microsurgical needle holders have unreasonable structural designs, are bulky with poor toughness, and have a short service life.

[0003] In summary, the related technologies urgently need to be improved. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a microsurgical needle holder in view of the deficiencies of the existing technologies. A blade and a blade avoidance hole are installed at the rear end of the clamping part. After the suture operation is completed, when cutting the thread, directly push the clamping part forward to make the thread fall on the cutting edge of the blade, and then close the clamping part by holding the handheld part to complete the cutting of the thread, which is very convenient to operate. A limit post is provided to limit the movement range of the handheld part within a safe operation range, which is beneficial to extend the service life. Anti-slip structures are provided on both the clamping part and the handheld part, greatly increasing the working stability, being easy to use and having strong practicability.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A microsurgical needle holder includes a first pliers rod, a second pliers rod, a first reset spring piece and a second reset spring piece. The first pliers rod includes a first clamping part, a first hinge part and a first handle part, which are connected in sequence. The second pliers rod includes a second clamping part, a second hinge part and a second handle part, which are connected in sequence. The first hinge part and the second hinge part are hinged by a pin. One end of the first reset spring piece is connected to the end of the first handle part, and one end of the second reset spring piece is connected to the end of the second handle part. The other end of the first reset spring piece is clamped with the other end of the second reset spring piece. A blade is arranged in the area of the clamping surface of the first clamping part close to the first hinge part, and an avoidance hole matching the blade is arranged in the area of the clamping surface of the second clamping part close to the second hinge part.

[0007] In one embodiment, a first anti-slip structure is arranged on the clamping surface of the first clamping part.

[0008] In one embodiment, a second anti-slip structure is provided on the outer side surface of the first handle portion.

[0009] In one embodiment, a third anti-slip structure is provided on the clamping surface of the second clamping portion.

[0010] In one embodiment, a fourth anti-slip structure is provided on the outer side surface of the second handle portion.

[0012] In one embodiment, strip-shaped grooves are provided on the inner side surface of the first handle portion and / or the inner side surface of the second handle portion.

[0013] In one embodiment, a clamping protrusion is provided at the end of the first return elastic piece, a clamping hole is provided at the end of the second return elastic piece, and the first return elastic piece is clamped with the clamping hole on the second return elastic piece through the clamping protrusion.

[0014] In one embodiment, the first clamping portion, the first hinge portion and the first handle portion are integrally formed, and the first clamping portion is a strip-shaped conical structure.

[0015] In one embodiment, the second clamping portion, the second hinge portion and the second handle portion are integrally formed, and the second clamping portion is a strip-shaped conical structure.

[0016] The beneficial effects of the present utility model are as follows: In application, medical staff hold the first handle portion and the second handle portion with one hand at the same time to work. During the work, under the combined clamping action of the first clamping portion and the second clamping portion, the surgical needle is clamped, and then the wound of the patient is sutured with a needle and thread. Under the elastic action of the first return elastic piece and the second return elastic piece, when the hand of the medical staff releases the force, the first clamping portion and the second clamping portion release the suture needle, thereby realizing multiple repeated suture operations; after the suture operation is completed and the thread needs to be cut, the working medical staff holds the first handle portion and the second handle portion and directly pushes forward. At this time, the first clamping portion and the second clamping portion also push forward synchronously, and then the thread slides onto the cutting edge of the blade. Then, by pressing the first handle portion and the second handle portion at the same time, the first clamping portion and the second clamping portion are closed to complete the cutting of the thread. The avoidance hole is used to accommodate the blade, so that the thread cutting work can be completed smoothly and efficiently. At the same time, it is beneficial to reduce the overall structure weight, increase the toughness of the overall structure, extend the service life, and is very convenient to operate with strong practicability.
