Abstract

The invention relates to a medical tong. The medical tong comprises a tong body with a tong head, and a step is arranged on the tong head; the medical tong is characterized in that the root portion or the edge of the step is provided with an alloy material part, the tong body is made from low-carbon stainless steel which is harder than HPC30 and obtained by quenching, the alloy material part is made by mixing C, Si, Mn, P, S, Ni, Cr, Mo and Cu, wherein the mass percent of the C ranges from 0.08 to 0.2, the mass percent of the Si ranges from 0.5 to 1.5, the mass percent of the Mn ranges from 0.1 to 0.8, the mass percent of the P ranges from 0.01 to 0.05, the mass percent of the S ranges from 0.005 to 0.02, the mass percent of the Ni ranges from 0.4 to 0.8, the mass percent of the Cr ranges from 5.5 to 13.5, the mass percent of the Mo ranges from 0.02 to 0.1, and the mass percent of the Cu ranges from 0.01 to 0.05. The medical tong and a manufacturing method thereof have the advantages that a tong opening is high in strength and rigidity, resistant in corrosion and the like; the tong opening is easy to machine, and the cost is saved.

Description

Medical calm and manufacture method thereof

Technical field

The present invention relates to a kind of medical jaw processing technology, particularly relate to oral medical jaw processing technology.

Background technology

Existing medical apparatus and instruments pincers class, the structure of cutting the class edge of a knife have following a few class substantially:

1. medical calm entirety is that middle carbon stainless steel material is directly processed into the edge of a knife after quenching.This type of edge of a knife, because hardness is not high after the material quenching of rustless steel self, can not meet the requirement cutting off steel wire.

2. medical calm entirety is that high-carbon stainless steel material is directly processed into the edge of a knife after quenching.This type of edge of a knife, because after the material quenching of rustless steel self, integral hardness is too high, caliper is just more crisp, and difficult processing.Because the general phosphorus content of this type of material is higher, rustless property is poor.Although this type of edge of a knife hardness improves a lot, the hardness sheared needed for steel wire for medical industry also has certain gap.

3. the low or middle carbon stainless steel of medical calm caliper is made, edge of a knife position welding high hardness material.Though the problem of edge of a knife hardness adopting the method to process solves, due to low or middle carbon stainless steel and jaw high hardness material welding performance very poor, two kinds of different materials are difficult to weld together, so generally all adopt the mode of soldering, after welding, weld is easy to change, and cutter head easily comes off.

Summary of the invention

Object of the present invention is for shortcoming of the prior art, develops a kind of edge of a knife high rigidity, high strength, corrosion-resistant medical calm and its manufacture method.

In order to achieve the above object, medical calm designed by the present invention, comprise the caliper with binding clip, step is arranged with at clamp head part, it is characterized in that root or the edge of step are provided with alloy material portion, wherein said caliper is made by the low carbon stainless steel material of more than the HRC30 obtained that quenches, and described alloy material portion is by C, Si, Mn, P, S, Ni, Cr, Mo and Cu is mixed, wherein the mass percent of C is 0.08-0.2, the mass percent of Si is 0.5-1.5, the mass percent of Mn is 0.1-0.8, the mass percent of P is 0.01-0.05, the mass percent of S is 0.005-0.02, the mass percent of Ni is 0.4-0.8, the mass percent of Cr is 5.5-13.5, the mass percent of Mo is 0.02-0.1, the mass percent of Cu is 0.01-0.05.

The manufacture method of above-mentioned medical calm is after whole caliper machine-shaping, step is processed at binding clip position, then be combined with binding clip after the root of step or edge utilize laser melting and coating technique by alloy powder fusing, by spark cutting or mach method, excess stock is excised again, the jaw required for formation.

The medical calm that the present invention obtains and manufacture method thereof have a little following:

1. jaw has high strength, high rigidity, the characteristic such as corrosion-resistant.

2. jaw processing is simple, cost-saving.

Fig. 2 is structural representation after the embodiment of the present invention 1 finished product.

Fig. 3 is the another kind of finished product structure schematic diagram of the embodiment of the present invention 1.

Detailed description of the invention

Below by embodiment, the invention will be further described by reference to the accompanying drawings.

Embodiment 1.

As Fig. 1, 2, shown in 3, the medical calm that the present embodiment describes, comprise the caliper 1 with binding clip, step 2 is arranged with at clamp head part, root (as Fig. 3) or the edge (as Fig. 2) of step 2 are provided with alloy material portion 3, wherein said caliper 1 is made by the low carbon stainless steel material of more than the HRC30 obtained that quenches, and described alloy material portion is by C, Si, Mn, P, S, Ni, Cr, Mo and Cu is mixed, wherein the mass percent of C is 0.08-0.2, the mass percent of Si is 0.5-1.5, the mass percent of Mn is 0.1-0.8, the mass percent of P is 0.01-0.05, the mass percent of S is 0.005-0.02, the mass percent of Ni is 0.4-0.8, the mass percent of Cr is 5.5-13.5, the mass percent of Mo is 0.02-0.1, the mass percent of Cu is 0.01-0.05.

The manufacture method of above-mentioned medical calm is after the machine-shaping of whole caliper 1, step 2 is processed at binding clip position, then be combined with binding clip after the root of step or edge utilize laser melting and coating technique by alloy powder fusing, by spark cutting or mach method, excess stock is excised again, the jaw required for formation.
