Abstract

The utility model discloses an electric scalper for the prostate gland. The insulated outer layer of the tool bar is a porcelain tube, the conducting core is the copper wire, and the blade is the Ni-Cr high resistance-heat alloy wire. The utility model has the advantages of low cost and long service life. The utility model provides the favorable condition for the prostate excision operation in vitro.

Description

Electric scalper for prostate gland

This utility model relates to a kind of medical apparatus and instruments, is applicable to the resectosccope electric knife, is the improvement to existing prostate excision electric knife.

Since resectosccope be used for clinical since, its electric knife is the crucial adnexa of resectosccope, it also is expendable part, show that as Fig. 1 its knife bar is by rustless steel (1), heat resistant plastice pipe (2), conductive copper wire (3) is made, blade adopts tungsten filament to make, and in operation, blade is a consumable accessory, once scaling loss, whole cutter is all scrapped, and usually, once operation will consume two above electric knifes, present domestic this product that still do not have, all imports cause very big waste, and many hospitals can not be carried out this operation greatly because of the electric knife consumption.

The purpose of this utility model is to overcome the above-mentioned shortcoming in the prior art, designs the electric knife of the anti-scaling loss of a kind of new material.

Fig. 5 specifies accompanying drawing for specification digest.

Among Fig. 2-Fig. 5:

1-porcelain tube 2-conductive copper wire 3-knife bar 4-cutter head 5-blade 6-plastic tube

Narrate by reference to the accompanying drawings the utility model content:

This utility model is (as Fig. 2, shown in Figure 3), form by three parts, first is knife bar (3), second portion is cutter head (4), third part is blade (5), and knife bar is by porcelain tube (2), and conductive copper wire (1) is made different length, the cross section is circular bar, conductive copper wire (1) is contained in the porcelain tube (2), and cutter head (4) is similar to " U " shape, is made by high-temperature resistance plastice pipe (6) and conductive copper wire (1).Blade (5) can be made into various difformities as required.(showing) as Fig. 4.Blade is made by nickel-chromium high-resistance heat seal spun gold.

Compare with prior art, this utility model low cost of manufacture, blade life has prolonged more than one times than prior art, has also brought the reduction of the outer excision cost of body of prostate simultaneously.

Embodiment:

Fig. 5 is four embodiment of the present utility model, and the cutter head shape is respectively " V " shape, " U " shape and ellipse, and linear in actual use, also can manufacture the shape electric knife different with length according to different needs.

Claims

1, a kind of prostate excision electric knife is made up of knife bar, cutter head, blade, it is characterized in that the knife bar skin adopts the ordinary porcelain pipe to make, and blade adopts nickel chromium triangle high-heat alloy silk to be bent into different shape.
