In order to solve the technical problems, the invention provides a novel medical hemostatic forceps with a guide wire hole, which specifically comprises: the right side clamp handle, the left side clamp handle, the connecting pin and the positioning pin;

the right side clamp handle is formed by overlapping a first right side clamp handle piece and a second right side clamp handle piece which have the same shape;

the first right-side forceps handle piece and the second right-side forceps handle piece are positioned through the positioning pin, semicircular through grooves are formed in the first right-side forceps handle piece and the second right-side forceps handle piece along the forceps handle body direction respectively, the first right-side forceps handle piece and the second right-side forceps handle piece are connected and formed through brazing, the right-side forceps handle is formed, and the two semicircular through grooves are correspondingly overlapped to form the wire guide through hole of the right-side forceps handle.

Furthermore, the left forceps handle is not provided with a guide wire through hole;

the right side pincers handle with the left side pincers handle passes through the connecting pin is connected, forms novel medical hemostatic forceps.

In conclusion, the novel medical hemostatic forceps with the wire guide hole provided by the invention at least has the following advantages:

in the embodiment of the invention, as the wire guide hole is formed in the forceps handle at one side, the technical problem that a deep and long small hole is processed in the forceps handle and the hole is not a straight hole is solved, and the wire guide hole and the wire guide can simultaneously enter the human tissue for operation in a medical minimally invasive operation; moreover, the medical hemostatic forceps is simple in structure, convenient to process and high in practicability.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The novel medical hemostatic forceps with the guide wire hole provided by the invention is described in detail by taking specific embodiments.

Examples

The embodiment of the invention provides a novel medical hemostatic forceps with a wire guide hole, and particularly refers to the structural schematic diagrams of fig. 1-4.

The novel medical hemostatic forceps specifically comprise aright forceps handle 1, aleft forceps handle 2, a connectingpin 3 and apositioning pin 5; the rightside plier handle 1 is formed by overlapping a first right sideplier handle piece 21 and a second right sideplier handle piece 22 which have the same shape;

the first right-side handle part 21 and the second right-side handle part 22 are positioned through thepositioning pin 5, the first right-side handle part 21 and the second right-side handle part 22 are respectively provided with a semicircular throughgroove 6 along the handle body direction, the first right-side handle part 21 and the second right-side handle part 22 are connected and formed through brazing to form a right-side handle 1, and the two parts of the semicircular throughgrooves 6 are correspondingly overlapped to form a wire guide throughhole 4 of the right-side handle 1.

Furthermore, theleft forceps handle 2 can be provided with no guide wire through hole; the right forceps handle 1 and theleft forceps handle 2 are connected through a connectingpin 3 to form the novel medical hemostatic forceps.

In the embodiment of the invention, theleft forceps handle 2 can be provided with no guide wire, the manufacturing process is a common forceps handle structure of the hemostatic forceps, and the right forceps handle 1 and theleft forceps handle 2 are connected through the connecting pin 3 (shown in figure 1) to form the complete novel medical hemostatic forceps.

Specifically, the assembling process of the novel hemostatic forceps provided by the embodiment of the invention is as follows: the two symmetrical halves can be made with the pincers handle on right side earlier, then processing out the half arc circular slot in order to form the seal wire hole on the base member, again with two halves pincers handle through the locating pin advance line location to the application is brazed and is welded and form the right side pincers handle, does not take the pincers handle of seal wire through-hole with the left side at last and rivets, thereby accomplishes the equipment of taking the novel hemostatic forceps in seal wire hole.

In addition, in the brazing process, the used brazing filler metal belongs to the biological safety range, and a biological toxicity test is carried out after the pliers are formed so as to verify the material selection and further ensure the safety of the material.

It should be noted that, according to the embodiment of the present invention, the structures of theright forceps handle 1 and theleft forceps handle 2 can be interchanged according to the actual application, that is, theright forceps handle 1 does not have a guide wire through hole, and theleft forceps handle 2 has a guide wire through hole. That is, the leftside caliper handle 2 can be defined as follows: the leftside pincers handle 2 is formed by first left side pincers handle spare and the superpose of second left side pincers handle spare that the appearance is identical completely, first left side pincers handle spare and second left side pincers handle spare pass through the locating pin location, and be provided with semi-circular logical groove respectively along pincers handle body direction on first left side pincers handle spare and the second left side pincers handle spare, first left side pincers handle spare and second left side pincers handle spare form leftside pincers handle 2 with brazing connection shaping back, the corresponding superpose of wire guide through-hole that forms left side pincers handle 2 in two parts semi-circular logical groove.

In the embodiment of the present invention, according to the actual application situation, the structures of theright forceps handle 1 and theleft forceps handle 2 may also be set to be the same, that is, both the right forceps handle 1 and theleft forceps handle 2 are provided with the wire guiding through hole, and the right forceps handle 1 and theleft forceps handle 2 have the same manufacturing process and structural features, which are specifically referred to the above description and are not repeated herein.
