Description
Technical field
This improvement utility model belongs to the medical operating articles for use, is specifically related to the laparoscopic surgery single-hole multi-passage puncture outfit, is applicable to Wicresoft's laparoscopic surgical instruments and is imported, operated by single hole.
Technical background
In recent years, Wicresoft's laparoscopic surgery development is rapid, and many apparatuses were modified into the many apparatuses importings in a hole by the 3-4 hole with frustrating card (thocar) importing in the past.This art formula is opened a little otch from patient's abdominal part, puts into single-hole multi-passage puncture outfit, can import various apparatuses, has both alleviated patient's wound, can produce again the effect of incision scar-free, welcome by doctors and patients.
At present, external successively report has Tri-port, quad-port, and SiLS port, the single-hole multi-passage puncture outfits such as Uni-x port wherein have and only establish through-hole type, must import apparatus with frustrating the card transition; The sealed valve passage is with in establishing of having, and need not frustrate the card transition; Perforator and otch location are also different, have with horn mouth inlay card location (SiLS) screens length unadjustable; Useful cone is inserted otch (Uni-x), can not locate voluntarily, must sew up.Although Tri-quad-port location length of pipe is adjustable, and adjusting is very inconvenient, operating difficulties.More than mostly be integral structure, take out the excision thing and must unload with getting thing bag or integral body, also there is the risk of pathological tissues contamination of incision in troublesome poeration not only.Above multiple perforator imports instrumentation and frustrates the card transition, and minority is provided with seal channel, also adopts the gelinite sealed valves more, and reliability is not good.The single-hole multi-passage puncture outfit weak point is badly in need of updating.Once application has utility model patent CN202199581U single-hole multi-passage puncture outfit for this reason, and this still has the not enough improvements that need.
Summary of the invention
The purpose of this improvement utility model invention is the deficiency that overcomes conventional art; improve single-hole multi-passage puncture outfit; it is characterized in that improving that single-hole multi-passage puncture outfit retracts cover (abbreviation protective sleeve) by the single hole incision protection and multichannel seal (abbreviation seal) combines; protective sleeve and seal can split type mutual assembly; also combining is integral the formula use; wherein the multichannel seal is provided with 2 or 3 or 4 valve-type passages or establishes 3 or 4 ports valve formula passages, is provided with 1 or 2 breather lines.
The technical scheme that its technical problem that solves this utility model adopts is:
Single-hole multi-passage puncture outfit is comprised of protective sleeve and seal, can respectively be designed to two kinds of forms.The first protective sleeve is the elastic pipeline of double horn mouth shape; consisted of by outer snap ring, interior snap ring and thin film pipeline three parts; its snap ring and pipeline all have elasticity and elastic recovery; import operative incision by interior snap ring strain; in inlay card otch stomach wall after its elastic recovery; made by inside and outside snap ring and the effect of pipeline elastic recovery that pipeline attaches, expansion cut, have to retract and protect cutting action, protective sleeve mates as pedestal and seal.
The second protective sleeve is circular cone shape or cylindric, is comprised of the outer snap ring of elasticity, interior snap ring and flexible duct three parts, and wherein the enhancing ring cross section of outer snap ring is dumb-bell shape, 8-shaped or oblateness.Inside and outside snap ring has elasticity and elastic recovery, and the thin film pipeline is pliability.Behind interior snap ring importing, inlay card otch; radially during the outer snap ring of turnup; flexible duct shortens thereupon; its effective tension bore increases thereupon; until stop turnup, it is maximum that pipe diameter and tension force reach, and pipeline attaches, expansion cut; have hands and help and retract and protect cutting action, the protective sleeve behind the location is as pedestal and seal coupling.
The first seal is plate-like, is combined into by shell and multichannel elastomer platform, and housing peripheral hardware circular orientation convex slot is established multichannel elastomeric seal platform in the shell.The platform compartment is positioned at the bottom, establishes a plurality of (being generally two, three or four) on the compartment with vertical passage and one or two breather line of sealed valve.Valve can be designed to the non-return crack of elastica and the springhole seal group is fit.Housing outer ring locating slot convex-concave ring supplies and the outer chimeric location of snap ring of protective sleeve, the outer snap ring turnup sealing of housing peripheral hardware shirt rim and protective sleeve.
The second seal is mesa-shaped, is provided with two, three or four ports valve formula passages, one or two vent line.Ports valve formula passage establishes the elastic packing hole and the elasticity slit valve splits the jitty two ends.All can before and after splitting.Shell mechanism is the same.So the sealing platform can directly import the apparatus assurance into and out of sealing, also can adopt the plug-in card transition.Ports valve formula passage is with can the suit sizes exchange of apparatus operation of its enough little closed hole warp and high resiliency.Enlarge and import the apparatus size range.
Above two kinds of protective sleeves; two kinds of seals can be combined into four kinds of multi-form perforators mutually; when a kind of protective sleeve of pattern is inserted otch; behind the location; can mate with two kinds of form seals seal annular groove and protective sleeve annular groove pressing sealing, seal shirt rim turnup; seal the outer snap ring of protective sleeve, improve the location sealing reliability.For preventing that slippage from can add hoop again and strengthening.
This utility model has following beneficial effect:
1. this utility model single-hole multi-passage puncture outfit, but the split Assembling use, but also assembled in advance is done whole the use.
2. this split type perforator is with ring, groove inlay card, and location is sealed in the shirt rim, sealing assembling is convenient, fast, sealing is reliable, but takes out resection organization behind the removal seal, prevent that otch from polluting and plant.
3. two kinds of incision protection retractors are made pedestal, and its duct height is capable of regulating and thickness of abdominal wall coupling all.
4. but a perforator seal compartment is established ports valve formula passages regulate closed hole through expansion instrument size matching range, and is easy to use.
In the perforator sealed valve design with the non-return crack of elastica and springhole combination sealing, visual adjustable outside non-return crack places, seal more reliable.
