Description
Technical field
The present invention relates to Medical Devices, more particularly, to a kind of manufacturing method of the medical sub- needle assemblies of ablation.
Background technology
Radiofrequency ablation technology is the minimally invasive common operation method in field of medical treatment.It is widely used in movement doctor
In the operations such as, backbone, ear nose larynx.Its surgical apparatus system is excited conducting medium to plasma by the electrode tip of front end
Body state, and the plasma slab of a high aggregation is formed in surrounding them, utilize plasma high speed operating ion
Kinetic energy interrupts organic molecule chain, so as to crack molecular level, generates the vaporization of controllable precise, cutting, ablation, haemostatic effect.
The medical sub- needle assemblies of ablation are exactly the electrode part of this equipment, are assemblied by electrode tip and ceramic tube.During production, existing skill
Art is using medical glue, and the two is assembled together.It, can when electrode is contacted with human skin in art due to being glue adhesion
It can generate allergy phenomenon.Secondly, in surgical procedure, low-temperature plasma brief energization also influences whether the fastness of glue, meeting
Have it is a certain proportion of come off, cause operation risk.The product retention period 3 years due to glue failure easy to aging, causes and comes off, because
This will moderately have certain requirement to the temperature of storage.
Chinese patent CN104173105A discloses a kind of bipolar needle of novel ablation, including shank, syringe needle, interior insulation set
Pipe, electrode casing, external insulation casing pipe, isolated insulation layer and the first PTC casings, syringe needle are integral with shank, and syringe needle is arranged on
Shank one end is relatively large in diameter and pointed, and the position on shank against syringe needle is arranged with isolated insulation layer, isolated insulation layer one
Interior insulation casing, electrode casing and external insulation casing pipe are equipped on the shank of side successively, is set on the syringe needle of isolated insulation layer opposite side
There are the first PTC casings, but this kind melts bipolar needle and still can not solve the problems, such as that aging comes off.
Invention content
Human body is more pacified it is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of
Entirely, the manufacturing method of the sub- needle assemblies of medical ablation without the risk that comes off in art.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of manufacturing method of the medical sub- needle assemblies of ablation, using following steps：
(1) it is 5 by weight by porcelain glaze powder and deionized water:4~12:7 mixed preparing composite adhesives；
(2) it is applied in the assembling side of electrode tip and spreads adhesive；
(3) electrode tip and ceramic tube are assembled；
(4) product assembled is placed in high-temperature process FIxed abrasive article, then grinding tool is placed in high temperature furnace and carries out height
Temperature processing, making obtain the medical sub- needle assemblies of ablation.
The porcelain glaze powder main ingredient is silicon and magnesium.
Adhesive is dipped using painting brush in step (2) and smeared two layers in the assembling side of electrode tip, between controlling two layers
There is no gap and adhesive will not overflow, the number of plies can influence scribble effect too much, too thin to influence sintered fastness, cause de-
It falls, and adhesive is smeared and uniformly need to not applied fastness after influence sintering of attending the meeting, cause and come off, smearing excessive spilling can influence to produce
The product later stage uses
Step aligns the pilot hole of electrode tip and ceramic tube in (3), and electrode tip and ceramic tube assembling is integral.
The temperature of step (4) high temperature processing is controlled at 1000-1500 DEG C, and time control is in 10-15min.High-temperature process
Temperature is too low or the time is too short, and sintering, which loosely causes, to come off, and temperature is too high or sintering time is too long can influence ceramic tube quality.
Compared with prior art, the present invention using enamel as connection medium, first, in operation with during human contact not
Allergic phenomena can be caused, secondly the composition of enamel and ceramics matches, after sintering very securely, without the risk that comes off.Third is being produced
Conventional stored condition is also only needed in terms of product storage, without excessive control, the prepared medical sub- needle assemblies of ablation more pacify human body
Entirely, and make the electrode tip of medical equipment more secured, come off risk in no art, substantially increases the safety of operation.
