Description
Technical field
The present invention relates to Minimally Invasive Surgery apparatus, more particularly to a kind of puncture outfit structure.
Background technology
Puncture outfit is the artificial channel for entering body cavity in a kind of Minimally Invasive Surgery (especially hard tube endoscope-assistant surgery) for setting up
Operating theater instruments.Puncture outfit generally comprises thimble assembly and puncture needle two parts.Its clinical general occupation mode is：First suffering from
Osculum is cut on person's skin, then puncture needle is run through into thimble assembly, the distal end of puncture needle exceedes the distal end of thimble assembly, then together
Enter body cavity via body wall is penetrated at skin openings.Operative doctor grips puncture outfit and applies larger puncture procedure power, is used for
Overcome the resistance for puncturing and cutting open tissue, and expansion and the tissue that swells resistance.When the distal end of puncture needle and thimble assembly is whole
When body penetrates patient's body wall, the resistance suddenly disappears, and doctor has little time to stop force or due to effect of inertia, the puncture needle
Distal end may accidental injury patient's interior tissue.To reduce this accident trauma risk, numerous designs person has carried out substantial amounts of
Innovative design, has formd knife protection puncture needle, no three major classes of knife puncture needle and visual puncturing pin." the having knife " refers to containing gold
Belong to blade, " no knife " refers to without metal blade.Puncture needle containing plastic cement blade is commonly known as without knife puncture needle, and this is
This area is sanctified by usage.The visual puncturing pin is often referred to containing hollow endoscope path way, and can be led in puncture process
Cross the puncture needle for coordinating the organization factorses of monitoring needle tip end regions appearance in real time with endoscope.Different types of puncture needle
Respectively there are advantage and inferior position, operative doctor often formulates rational according to operation species, operative site and patient profiles' comprehensive consideration
Set up the method for puncture channel and select matching puncture needle.
In hard tube endoscope-assistant surgery, it need to generally set up and maintain stable pneumoperitoneum, to obtain enough operation technique spaces.Set
Tube assembly is generally by sleeve pipe, shell, diaphragm seal (also known as instrument seal) and zero sealing (also known as automatic-sealed) composition.Described sleeve pipe
Penetrated outside body cavity to body cavity, the passage of body cavity is passed in and out as apparatus.The shell connects sleeve pipe, zero sealing and diaphragm seal
Into a sealing system.Zero sealing is generally not provided the sealing for insertion instrument, and is closed automatically when apparatus is removed
And form sealing.The diaphragm seal banding apparatus and forms sealing when apparatus is inserted.Up to the present, in laparoscopic surgery often
It is generally normal between 3~15mm with the diameter (or maximum peripheral dimension) of apparatus, and it is used as the sleeve pipe group of apparatus access way
Part, it is corresponding, be typically divided into 3mm by the nominal of its sleeve pipe interior diameter, 5mm, 8mm, 10mm, 11mm, 12mm and
15mm equal diameter specifications.
The puncture needle or thimble assembly are generally divided into reuse and disposable two major classes.Reuse product usual
Must be simple in construction and reliable, easy to disassemble, cleaning is re-assemblied and two-stage sterilization, therefore reuse puncture needle or sleeve pipe
The ease of use of component is generally not so good as disposable product.Intersect sense because of the operation needs become increasingly complex, or for reduction
Risk is contaminated, or is preferably application experience, disposable wearing pricker and disposable sleeve component be in current laparoscopic surgery
Gradually substitute and reuse product.The extensive application of disposable wearing pricker or disposable sleeve component, adds somewhat to
Cost of performing the operation and the wasting of resources, increase the pressure of environmental protection.Moreover, to reduce foregoing accident trauma risk, it is described once
Property puncture needle it is generally complicated, part manufacture and assembling product cost are higher, but the disposable wearing pricker is only being penetrated
Using being once dropped during stomach wall, powerful contrast is formed with the cost of its great number.The bag of current disposable puncture device
Dress mode is usually that " sleeve pipe of 1 pin 2 " punctures product bag, i.e., single puncture needle and matching single thimble assembly are packaged in together
Client or hospital are supplied in one aseptic packing system and with germ-free condition.Another common manner of packing is described disposable
Puncture needle and thimble assembly are individually packed, self assemble when being used by client or hospital.To reduce cost, prior art bag
Containing a kind of " sleeve pipe of 1 pin 2 " puncture product bag, i.e., pack 1 puncture needle simultaneously in single aseptic packing system and 2 matching
Thimble assembly.Prior art also punctures product bag comprising another " sleeve pipe of 2 pin 4 ", i.e., comprising 1 5mm puncture needle and 2 with
Matching thimble assembly, in addition to the puncture needle (such as 10mm or 12mm) of another 1 major diameter and 2 it is matching big straight
Footpath thimble assembly.More packaged combinations are more rare.The one-time puncture product bag can generally reduce disposable wearing pricker
Consumption or reduction packing cost, a certain degree of saving operation cost.
Laparoscopic surgery is thought from coming out, always in fast-developing and change, is mainly shown as new operative model or hand
Art species is constantly created and promoted, and operation (such as Cholecystectomy) is also continuous known to numerous doctors
Improve and optimize.Generally, operation species gradually increases, and the operation that can be completed becomes increasingly complex, used in operation
Apparatus species is also more and more, and the method that puncture channel system is built in operation is also constantly improved or optimized.For example it is a kind of
In uterectomy, a part of doctor, which generally selects, sets up 1 10mm puncture channel and 3 5mm puncture channels, and crushing is picked-off
It is 15mm passages again to expand one of 5mm passages during uterus；And another part doctor generally selects and sets up 1 10mm puncture
Passage and 3 5mm puncture channels, crushing additionally set up a 15mm puncture channel again when picked-offing uterus.Such as a kind of stomach is cut
Except in operation, a part of doctor tends to " 5 puncture channel method ", i.e., 1 10mm passage, 1 12mm passage, 3 5mm passages.
Another part doctor tends to 6 puncture channel methods, i.e., 2 10mm passages, 1 12mm passage and 3 5mm passages.Such as abdominal cavity
Develop in videoendoscopic surgery earliest and using one of most ripe operation --- Cholecystectomy, 4 tiretube process are generally used all the time,
2 large diameter puncture channels and 2 small internal diameter puncture channel are set up in patient's stomach wall, are completed with 3 doctors.In recent years
It is being improved to 3 sleeve pipes and 2 doctors coordinates Completion Techniques, with Economy type medicine apparatus consumption and doctor's resource, reduction operation cost.
Enriched constantly with the species and operation method of laparoscopic surgery, existing disposable puncture product bag can not show
What is write is cost-effective.One those skilled in the art is it is contemplated that can design enough disposable products bags to meet difference
The demand of clinical scene.But have the technical staff necessarily understood for clinical link it is to be understood that the equipment pipe of hospital
Reason, the links such as preparation and operation technique of performing the operation generally have solidification flow or standard formula, and complicated collocation method is each by increase
The study of link and management cost, or even cause confusion.The design of the disposable puncture product bag, is not simple plus-minus
Combination, the actual disposable puncture product bag configuration of clinical practice of not fitting, or excessively complicated disposable puncture product bag
Configuration, it appears nonsensical to be also not necessarily to.However, being that reduction operation cost and convenient operation are carried out, product is reasonably punctured
Bag configuration, and optimization puncture channel Establishing scheme, be worth and in-depth study and should be continuously improved.
