Description
Technical field
The present invention relates to medical instruments field, and in particular to a kind of fish-eye type single-hole multi-passage puncture outfit, suitable for anal intestine
Surgery, laparoscopic surgery Minimally Invasive Surgery.
Background technology
In recent years, because wound is small, treatment time is short, patient pain is light, recovers the advantages that fast, the minimally invasive hand of laparoscopic surgery
Art is quickly grown.A small otch usually is opened in the belly of patient, then places a single-hole multi-channel on the otch and punctures
Device, inserts special lengthening operating theater instruments from the passage of single-hole multi-passage puncture outfit, and surgical doctor is supervised in high-tech display screen
Depending on, guiding under, in manipulating operating theater instruments, pathological tissues are detected in the abdominal cavity outside, coagulation, hemostasis, tissue separation with cut, stitch
The operation such as conjunction.The structure of single-hole multi-passage puncture outfit of the prior art is more and more perfect, still, in actual operation operating process
In, however it remains a problem.The operating theater instruments inserted in single-hole multi-passage puncture outfit passage is generally what is lengthened, operating theater instruments
Lengthening part all in shaft-like, the lengthening part of operating theater instruments is by a passage when being operated, such as doctor needs to adjust
When section work angle makes the operating theater instruments enter the various actions such as horizontal deflection, what its lengthening part neither one in passage can lean on determines
Site, doctor's operation is not convenient enough, and then may have impact on the stability and reliability of surgical operation.
The content of the invention
The present invention provides a kind of fish-eye type single-hole multi-passage puncture outfit, more logical using current single hole its object is to solve
The problem of operation is not convenient enough when road puncture outfit is operated.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of fish-eye type single-hole multi-passage puncture outfit, including
Upper cover body and tubular conduit body, upper cover body are fixedly connected with tubular conduit body, and in a state of use, upper cover body is placed in outside human body
Portion, tubular conduit body insertion inside of human body；The upper cover body is provided with multiple fish-eye shaped instrument channels, the fish-eye shaped instrument channel
It is made up of fish-eye shaped component and pedestal；The main body of the fish-eye shaped component is ring bodies, and ring bodies is provided with what is passed through for apparatus
Duct；There are at least three strong points in the pedestal so that fish-eye shaped component is seated in pedestal, the periphery of the ring bodies
Face is engaged with pedestal and forms spherical pair so that fish-eye shaped component can be present to rotate in vivo.
Relevant content in above-mentioned technical proposal is explained as follows：
1st, in such scheme, preferable scheme is that the right angle interface that can connect inside of human body is additionally provided with the upper cover body, is led to
The right angle interface is crossed to inside of human body gas injection or exhaust.
2nd, in such scheme, preferable scheme is the fish-eye shaped component from top to bottom by sealing Shang Gai, upper sealing, pad
Circle, sealing valve and flake noumenal seat intussusception are formed, and the sealing valve is check valve made of flexible material, the flake body
Seat is ring bodies, and the concrete shape of ring bodies can be drum type.
3rd, in such scheme, preferable scheme is that the fish-eye type single-hole multi-passage puncture outfit also includes sacculus, and sacculus is set
Put in the lower end of the tubular conduit body, sacculus gas injection conduit, sacculus note are provided with the outer surface of the tubular conduit body
Airway connects with the sacculus.Sacculus is made up of flexible materials such as semi-flexible rubber, and tubular conduit body also can be by semi-flexible
The flexible materials such as rubber are made, and both can easily make it that tubular conduit body was easy, easily enter cavity or incision of abdominal wall, and again might be used
To be more closely bonded cavity or incision of abdominal wall, ensure good sealing.
The design feature and beneficial effect of the present invention：The most important feature of the present invention is that upper cover body is provided with fish-eye shaped
Instrument channel.Fish-eye shaped instrument channel is made up of fish-eye shaped component and pedestal, and fish-eye shaped component is connected with pedestal by spherical pair
Make universal movement, the motion that centers of spherical pair can ensure that the reliable and stable of surgical instrument operation.That is, using flake
Formula single-hole multi-passage puncture outfit is carried out in surgical procedure, when doctor needs regulation work angle operating theater instruments is entered line displacement etc. respectively
During kind action, fish-eye shaped instrument channel has an anchor point that can be leaned on for the lengthening part long handle of operating theater instruments,
Doctor's operation is more convenient.
In addition, being provided with sacculus in the lower end of tubular conduit body, led on the outer surface of tubular conduit body provided with sacculus gas injection
Pipe, the sacculus gas injection conduit connect with sacculus, using the radian of sacculus itself tubular conduit body can be made to be easier, easily enter
Enter cavity or incision of abdominal wall, after cavity or incision of abdominal wall is entered, sacculus is resisted against on the inner surface of cavity or stomach wall, this
When, gas injection or water filling into sacculus using sacculus gas injection conduit can be while completing to seal according to different stomach wall/cavities
Thickness and automatically adjust the level altitude of stomach wall/cavity, if stomach wall/cavity is thicker, less inflation can be poured into sacculus
Amount, if stomach wall/cavity is relatively thin, can pour more aeration quantity into sacculus.
In a word, fish-eye type single-hole multi-passage puncture outfit of the invention is simple in construction, and operation technique facilitates for doctor,
It ensure that the stability and reliability of surgical operation.
