A kind of scope high frequency electric knifeTechnical field
The present invention relates to a kind ofly be used for the treatment of digestive system disease, apparatus that scope organizes high frequency cut to digestive tract under guiding, particularly relate to and a kind ofly cut function of injection scope high frequency electric knife integrally.
Background technology
In recent years along with the development of endoscopic technic, the biopsy of scope undertissue, endoscopic inferior mucosa excision, Endoscopic submucosal dissection are widely used, and it serves pivotal role to the early discovery of cancer of digestive tract hemorrhage, narrow, polypectomy and digestive tract, Diagnosis and Treat.The IT of cutter conventional in the market mainly Olympus insulate head cutter, the hook-shaped cutter of HOOT, TT triangular knife, Flex at least one steel wire cutter etc., when performing the operation under scope guides, scope is introduced into human body and finds pathological changes, apparatus carries out pathological changes labelling entering human body from endoscopic forceps channel, labelling backed off after random apparatus is used entry needle instead and is carried out tela submucosa injection, enter applicable electric knife after injection again to perform the operation, that in operation, changes that apparatus makes operation become is more loaded down with trivial details, and extends operating time and bring misery to patient.
The one combination electric knife of Hangzhou An Jiesi medical science and technology company limited, the patent No. is: CN104055572A, discloses a kind of column type combination high frequency surgical instrument.But do not relate to dado head cutting and function of injection.
A kind of endoscope-use high-frequency knife of Shanghai Elton Medical Devices Co., Ltd., the patent No. is: CN203861344U, discloses a kind of endoscope-use high-frequency knife.Equally do not relate to dado head cutting and function of injection yet.
Summary of the invention
For solving the problem, the invention provides a kind of novel scope high frequency electric knife, decreasing apparatus and changing, saving time and energy, more efficiently safer.
To achieve the above object, present invention employs following technical scheme:
There is provided a kind of scope high frequency electric knife, comprise handle portion and flat cutter head portion, flat cutter head portion comprises at least one piece of cutting blade, collets, insulation epitheca, energising silk, at least one needle tubing and mozzle; Handle portion comprises thumb rings, handle, slide handle, 6% female Luer, electrode and guide pipe; Described collets are fixedly mounted on the outer sheath distal of insulation, and cutting blade is fixedly installed on collets, and cutting blade is by the Electrode connection of be energized silk and handle portion; High-frequency electrical being connected on electrode to make cutting blade charged, by high frequency cutting excision pathological changes in operation.
Described collets are provided with at least one through hole, and needle tubing respectively correspondence is applied in the through hole on collets, and needle tubing can move freely in each self-corresponding through hole; Needle tubing be arranged on the mozzle insulated in epitheca and be connected, mozzle near-end is connected with 6% female Luer; Syringe is connected to 6% female Luer, by mozzle by Liquid transfer to needle tubing, then to be moved axially by the front and back that mobile slide handle controls needle tubing, the injection of the liquid such as normal saline, hemorrhage device can be carried out in clinical.
Described 6% female Luer is fixedly connected with slide handle, and slide handle moves axially and drives needle tubing and mozzle stretch out from the through hole collets or retract on handle.
Preferably: described cutting blade coated insulation block far-end, and run through by collets near-end with energising silk be connected.
Preferably: described collets are formed by macromolecular material or Ceramic manufacturing.
Preferably: described cutting blade has anti-stick coating, this anti-stick material that coating adopts is gold, copper or nickel.
Preferably: the material that described insulation epitheca adopts is the composite that PTFE, PE and PTFE and metal spring combination, PE and metal spring combine.Color is not limited to Huang, black, blue, orange, white etc.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention is owing to adopting above-mentioned technical scheme, and adopt cutter head portion to adopt flat duck tongue shaped structural design, cutter head portion adds metal electrode by insulator with holes and forms, and entry needle passes by the hole of insulator; Electric knife and entry needle are merged on an apparatus by this invention, decrease apparatus and change number of times, shorten operating time, alleviate the misery of patient in operation.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is made a detailed explanation.
As shown in Figures 1 to 3, the present embodiment provides a kind of specific embodiment of scope high frequency electric knife, as shown in Figure 1, a kind of scope high frequency electric knife, comprise handle portion and flat cutter head portion, flat cutter head portion comprises one piece of cutting blade 10, collets 11, insulation epitheca 12, energising silk 13, needle tubing 14 and mozzle 15; Handle portion comprises thumb rings 20, handle 21, slide handle 22,6% female Luer 23, electrode 24 and guide pipe 25; Described collets 11 are fixedly mounted on insulation epitheca 12 far-end, and cutting blade 10 is fixedly installed on collets 11, and cutting blade 10 is connected with the electrode 24 of handle portion by energising silk 13; High-frequency electrical being connected on electrode 24 to make cutting blade 10 charged, by high frequency cutting excision pathological changes in operation.
Described collets 11 are provided with a through hole, and needle tubing 14 is corresponding to be respectively applied in through hole that collets 11 are established, and needle tubing 14 can move freely in each self-corresponding through hole; Needle tubing 14 be arranged on the mozzle 15 insulated in epitheca 12 and be connected, mozzle 15 near-end is connected with 6% female Luer; Syringe is connected to 6% female Luer 23, by mozzle 15 by Liquid transfer to needle tubing 14, then to be moved axially by the front and back that mobile slide handle 22 controls needle tubing 14, the injection of the liquid such as normal saline, hemorrhage device can be carried out in clinical.
Described 6% female Luer 23 is fixedly connected with slide handle 22, and slide handle 22 moves axially and drives needle tubing 14 and mozzle 15 stretch out from the through hole collets 11 or retract on handle 21.
