Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a wire passer for thoracoscopic surgery. Background Art

[0002] Thoracic surgery is relatively deep, and during the process of ligating the blood vessels, one hemostat needs to be passed under the blood vessel, and another hemostat needs to clamp a thin wire and pass it to the other hemostat before the thin wire can be passed through the blood vessel for ligation. However, the thin wire needs to be straightened by an assistant, and manual straightening of the thin wire results in low surgical efficiency. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a technical solution: a wire passer for thoracoscopic surgery, comprising a first clamp body and a second clamp body, the middle part of the first clamp body is rotatably connected with the middle part of the second clamp body, the front end of the first clamp body is obliquely provided with a first clamping ring body, the first clamping ring body is arranged in an arc-shaped structure, and the top end of the first clamping ring body is arranged with an opening;

[0004] A second clamping ring is obliquely arranged at the front end of the second clamp body, the second clamping ring is arranged in an arc-shaped structure, and the top end of the second clamping ring is arranged in an open position;

[0005] The first clamping ring and the second clamping ring are closed to clamp the thin wire.

[0006] Furthermore, the clamping surface of the first clamping ring on the first clamping body is provided with a first protrusion, and the clamping surface of the second clamping ring on the second clamping body is provided with a second protrusion, so as to increase the stability of thin wire clamping.

[0007] The advantages of the utility model compared with the prior art are:

[0008] The utility model adopts a combination of a first clamp body, a second clamp body, a first clamping ring body, a second clamping ring body and other multiple structures, and utilizes two clamping ends on the first clamping ring body and the second clamping ring body to straighten the thin wire, so as to pass the straight line to the medical staff in the thoracoscopic surgery, thereby increasing the surgical efficiency of the medical staff, solving the problem of low efficiency caused by the assistant manually pulling the wire in the prior art, and facilitating the ligation of the blood vessels.

[0014] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0015] The utility model is described in detail with reference to the accompanying drawings.

[0016] The utility model provides a wire passer for thoracoscopic surgery in a specific implementation, comprising a first clamp body 1 and a second clamp body 2, wherein the middle portion of the first clamp body 1 is rotatably connected to the middle portion of the second clamp body 2, and a first clamping ring body 3 is obliquely arranged at the front end of the first clamp body 1, wherein the first clamping ring body 3 is arranged in an arc-shaped structure, and the top end of the first clamping ring body 3 is arranged with an opening;

[0017] A second clamping ring body 4 is obliquely arranged at the front end of the second clamp body 2. The second clamping ring body 4 is arranged in an arc-shaped structure, and the top end of the second clamping ring body 4 is arranged open.

[0018] The first clamping ring body 3 and the second clamping ring body 4 are closed to clamp the thin wire. Example

[0019] When the utility model is in use, the two clamping ends on the first clamping ring body 3 on the first clamp body 1 and the second clamping ring body 4 on the second clamp body 2 can be used to clamp the two ends of the thin wire. The two clamping ends can straighten this section of the thin wire, so that there is no need for an assistant to straighten the thin wire by hand. The clamp body with the above structure can be used as a wire passer to directly straighten the thin wire for passing a straight line to medical personnel in thoracoscopic surgery, thereby increasing the surgical efficiency of the medical personnel, solving the problem of low efficiency caused by assistants manually pulling the wire in the prior art, and facilitating the ligation of blood vessels.

[0020] As a further elaboration of the present invention, the clamping surface of the first clamping ring 3 on the first clamp body 1 is provided with a protrusion 1 5, and the clamping surface of the second clamping ring 4 on the second clamp body 2 is provided with a protrusion 2 6, so as to increase the stability of thin wire clamping.

[0021] As a further elaboration of the present invention, the protrusion 1 5 and the protrusion 2 6 are both elliptical protrusions, which are made of silicone material. The protrusions with the above structure can increase the friction between the thin wire and the clamping ring body, and increase the stability of the thin wire during the clamping process.

[0022] As a further elaboration of the present invention, the first pliers body 1 is provided with a first limit portion 7 near the handle, the second pliers body 2 is provided with a second limit portion 8 near the handle, and anti-slip patterns 9 are provided on the contact surfaces of the first limit portion 7 and the second limit portion 8.

[0023] As a further explanation of the present invention, the front ends of the first pliers body 1 and the second pliers body 2 are both inclined and bent upward.

[0024] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
