Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of self adaptive bendable of tissue lacuna and punctures
Device.
Background technology
Minimally Invasive Surgery is current operating main development direction, and the operation pathway that different operations are taked is different.Along with
The development of less invasive techniques, the requirement to operating theater instruments is more and more higher, and Special surgical instrument is all the more so.But for people's coelomic split
Relevant operation, majority is intended to use perforator, operates apparatus for guided operations.These perforators are big or use hard material
Material, such as medical stainless steel, or uses rigid plastics, can only support the use linear surgical apparatus.In clinical position, if
Running into special circumstances, need to use the apparatus with certain radian bending, traditional linear type perforator then cannot meet use,
Make operation or expand otch, causing huge wound and misery to patient；Abandon operative treatment, threaten the life peace of patient
Entirely.
Utility model content
The purpose of this utility model is to provide a kind of tissue lacuna self adaptive bendable perforator, existing to solve
In human body Minimally Invasive Surgery, there is the problem that the bending operating theater instruments of radian cannot use.
This utility model be employed technical scheme comprise that, tissue lacuna self adaptive bendable perforator, including passing through
The logical adaptor arranged and trocar sheath, adaptor is used for penetrating puncturing lever or operating theater instruments and passing from the opening part of trocar sheath,
Trocar sheath is to be provided with unidirectional film unit between the pipeline that flexible tubular structure, adaptor and trocar sheath are through, unidirectional thin
Film unit, for penetrating to trocar sheath direction from adaptor for puncturing lever or operating theater instruments, and the gas within stoping trocar sheath
Body is redirected back in adaptor.
Further, trocar sheath is the stainless steel flexible hose that inside and outside wall is smooth.
Further, the diameter of adaptor and the diameter of trocar sheath are than being (1.2-1.8): 1.
Further, film unit includes inverted cone thin film, the open bottom end of thin film towards adaptor, the top of thin film
Have gap.
The beneficial effects of the utility model are, arrange flexible trocar sheath so that it is not only can be with rectilinear surgical device
Tool with the use of, it is also possible to the operating theater instruments of elbow with the use of, improve surgical quality, alleviate wound and the pain of patient
Bitter.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model tissue lacuna self adaptive bendable perforator；
Fig. 2 a-Fig. 2 c is that this utility model tissue lacuna self adaptive bendable perforator penetrates tissue flexure nipper
Substep view.
In figure, 1. trocar sheath, 2. charging valve, 3. adaptor, the most unidirectional film unit, 5. tissue flexure nipper.
Detailed description of the invention
With detailed description of the invention, this utility model is described in detail below in conjunction with the accompanying drawings.
This utility model provides a kind of tissue lacuna self adaptive bendable perforator, sees Fig. 1, including hollow
Adaptor 3, connect bottom this adaptor 3 and have flexible trocar sheath 1, this adaptor 3 and trocar sheath 1 is worn for confession puncturing lever
Cross.
Trocar sheath 1 generally can be set to the smooth stainless steel flexible hose of outer wall, such as outside and be provided with smooth plastics tube wall
Corrugated tubing structure, so can ensure that the smooth of trocar sheath 1 outer wall, it is to avoid people's in-vivo tissue is caused damage, outside making simultaneously
Sleeve pipe 1 has certain elasticity and rigidity, it is simple to operation technique.
Seeing Fig. 2 c, trocar sheath 1 is set to bend by this utility model, and can be according to penetrating surgical device therein
The flexible pipe of the profile generation adaptability deformation of tool, so, allows for this perforator, not only can be for linear surgical device
Tool passes through, and is also equally applicable to passing of elbow operation tong so that the scope of application of this perforator is wider, operates more square
Just.
Meanwhile, trocar sheath 1 is provided with charging valve 2, can inflate in trocar sheath 1, body cavity can be increased
Interior space size, beneficially operation technique.
In trocar sheath 1, the one end near this adaptor 3 is provided with the unidirectional film unit 4 with retraction function, thin film list
Unit 4 includes inverted cone thin film, the open bottom end of thin film towards described adaptor 3, and the top of thin film has gap.Normality
Under, the gap on thin film is in closure state, it is ensured that the gas in trocar sheath 1 will not enter in adaptor 3；And puncture using
During bar, puncturing lever can be strutted gap, and be passed into from gap in trocar sheath 1；After taking out puncturing lever, this gap meeting
Natural closure.
The diameter of this adaptor 3 is (1.2-1.8) with the diameter ratio of trocar sheath 1: 1, and such setting makes in operation, with
Time use two perforators time, two-by-two adaptor 3 between will not produce interference, use convenient flexibly.
Fig. 2 a-Fig. 2 c represents that this utility model tissue lacuna self adaptive bendable perforator penetrates tissue flexure and grabs
The view step by step of pincers.Referring specifically to Fig. 2 a, use tissue flexure nipper 5 through tissue of the present utility model
During lacuna self adaptive bendable perforator, first the leading portion of tissue flexure nipper 5 is stretched into trocar sheath 1；See Fig. 2 b, continuing
Continuing during stretching into, the bending section of tissue flexure nipper 5 is put into trocar sheath 1, owing to trocar sheath 1 is flexible pipe, then trocar sheath 1
It is bent to conform to the shape of the bending section of tissue flexure nipper 5 the most therewith；See Fig. 2 c, tissue flexure nipper 5 to be adapted to curved
After tune passes trocar sheath 1 completely, this trocar sheath 1 is enclosed within tissue flexure nipper 5 back segment, and trocar sheath 1 recovers linearity simultaneously
State.Through above-mentioned procedure declaration tissue of the present utility model lacuna self adaptive bendable perforator, it is possible not only to fit
Answer linear surgical apparatus, it is also possible to be well adapted for the use of the bending operating theater instruments of radian.
