Abstract

The utility model relates to an AC/DC dual purpose minitype operation hemostat used in the minitype operation, and comprises a transformer, conducting wires, a pen body casing, a micro switch, copper pipelines and resistors. Two conducting wires leaded out from the transformer get into the pen body from the tail part of the pen body casing, one conducting wire is connected with the copper pipeline, and the other conducting wire is connected with the copper pipeline through the micro switch, and the remote ends of the conducting wires are connected with the both ends of the resistance wire. The utility model is small and light, the operation, the carrying and the keeping are easy, and the small size changes the deficiency of the largeness of the host machine and the bulkiness of the original hemostat; during the operation, closeburning substances cannot form at the contacting points by the pen of the hemostat and the human organism, electric spark and electric stimulation cannot occur, thus the operation can be accurate.

Description

AC and DC electricity dual-purpose miniature surgical hemostasis device

Technical field

This utility model relates to a kind of AC and DC electricity dual-purpose miniature surgical hemostasis device, belongs to the medical blood apparatus of controlling.

Background technology

At present, mostly the surgical hemostasis apparatus that domestic hospital uses is relatively large equipment, almost be not exclusively used in the haemostat of small-sized operation or use extremely inconvenient, existing high frequency electric knife and bipolar coagulation haemostat, use when comparatively being fit to large and medium-sized operation, discovery has the following disadvantages in the use: 1, must use having under the situation of alternating current power supply; When 2, being expert at the minor operation hemostasis, actively little with art district tissue contact surface, resistance is excessive, easily produces electric spark, the vital tissues such as hemostasis point peripheral nerve, blood vessel of burning; 3, in the surgical hemostasis process, haemostat with organize contact point easily to form the close-burning thing, and influence its continuously normal use; When 4, using haemostat, it produces the electricity impulsion with organizing the contact point place, can cause the contraction of muscle tissue motion, and have influence on the accuracy of operation technique, when particularly using, easily cause the damage of surrounding tissue, bring great inconvenience to the patient at the less position of surgical field of view.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of volume little, use easy to operate, the AC and DC electricity dual-purpose miniature surgical hemostasis device of small-sized operation special use.

The purpose of this utility model is achieved in that it is made up of transformator, lead, handwriting shell, microswitch, copper pipe line and resistance, its structural feature is: two leads that transformator is drawn are entered in the handwriting by the afterbody of handwriting shell, wherein one directly is connected with the copper pipe line, another root is connected with the copper pipe line by microswitch, and the far-end of two copper conductors is connected with the resistance wire two ends respectively.

Described microswitch is fixed in the handwriting, and hands touches the surface that part is exposed handwriting.

Described hemostasis nib for the copper pipe line with expose resistance wire and be connected.Described transformator also can be the alkaline battery group.

This utility model is compared with existing haemostat, has following obvious advantage:

1, volume is little, and weight is extremely light, is easy to operation technique, carries and takes care of, and is very light and handy during use, changes that hemostatic device main frame volume was big in the past, and heavy deficiency;

2, in the use, haemostat is written and organize the contact position not form the close-burning thing, thereby does not influence its normal continuously use;

3, in the use, do not produce electric spark, do not have the electricity irritation phenomenon again, in the delicate procedure of the being expert at process, operation technique is more accurate;

4, by the haemostat microswitch open-interval is controlled, or when using alternating current power supply to the adjustment of three class of transformator, make its temperature that produces different needs, make minor operation hemostasis, the easier grasp of cutting;

5, when minor operation is used, can utilize haemostat that subcutaneous tissue, muscular tissue and part superficial tumor are cut, play the effect of miniature electric knife;

6, external power supply device and handwriting part form the constant power requirement through test, are easy to production and assembly;

7, resistance wire and support are durable components, and be not fragile;

8, low cost of manufacture has economic, practical characteristics, has the vast market development prospect.

The explanation of accompanying drawing drawing

Accompanying drawing is this utility model structural representation.

The specific embodiment

Below in conjunction with drawings and Examples in detail this utility model is described in detail.

This utility model is a kind of friendship, unidirectional current dual-purpose miniature surgical hemostasis device, as shown in drawings, it is by transformator 1 or alkaline battery group, lead 7, handwriting shell 2, microswitch 3, copper pipe line 4 and resistance wire 5 are formed, two leads 7 that transformator 1 is drawn enter in the handwriting from the afterbody of handwriting shell 2, wherein a lead is guided the handwriting front end into from handwriting one side opening and directly is connected with copper pipe line 4, another root is with after the input of microswitch 3 is connected, draw with copper pipe line 4 from outfan again and be connected, microswitch 3 is provided with two holes, in handwriting, hands touches the surface that part is exposed handwriting by handwriting inner bulge part positioning and fixing in these two holes.The far-end of two copper pipe lines 4 is connected with the resistance wire two ends.Copper pipe line 4 parts protrude in outside the handwriting tip, and far-end all is connected and fixed with the two ends of same resistance wire 5.After handwriting shell 2 is involutory, be fixed with each screw 6 up and down.Hemostasis nib for the copper pipe line with expose resistance wire and be connected.Described transformator 1 also can be the alkaline battery group.

Operation principle of the present utility model: after the energized, electric current enters manual microswitch 3 through lead 7, during switch closure, electric current forms power conversion at resistance wire 5 places, produce heat effect, by regulation and control 3 opening times of microswitch or regulation and control transformer switch, the amount of heat that control nib portion resistance wire produces is to reach hemostasis or various objectives and requirement when cutting and organizing.

Claims

1, a kind of AC and DC electricity dual-purpose miniature surgical hemostasis device, form by transformator, lead, handwriting shell, microswitch, copper pipe line and resistance, it is characterized in that: two leads that transformator is drawn are gone into to handwriting by the afterbody of handwriting shell, wherein one directly is connected with the copper pipe line, another root is connected with the copper pipe line by microswitch, and the far-end of two copper conductors is connected with the resistance wire two ends.
