Abstract
The utility model belongs to the field of medical instrument technology, it is related to a kind of dedicated liver retractor of laparoscope, including holding rod and hook retractor, hook retractor is the coupler body that shape is in U-shape, coupler body when operation using U-shaped is inserted into liver lower end picking-up liver and performs the operation, and the coupler body of the hook retractor shape that is in U-shape will not scratch or puncture liver, avoid and cause to damage to liver, reduce the dangerous risk of operation；The utility model production simultaneously is simple, easy to use, reduces manpower and operation cost, and simplifying operation method reduces operating difficulty, has good social effect.
Description
Technical field
The utility model relates to a kind of surgical instruments, belong to the field of medical instrument technology, especially relate to
And a kind of dedicated liver retractor of laparoscope.
Background technique
Patient need to put down on operating table to be lain in laparoscope operation on liver, and the liver of patient is because gravity can paste at this time
It being attached to the bottom in abdominal cavity, to shelter from the affected part for needing to perform the operation, it is therefore desirable to tool is performed the operation to lift, draw liver,
Hospitals at Present is stirred and is drawn to liver usually using fan-shaped forceps, but the blade of fan-shaped forceps is very thin, and the quality of liver is again
It is tenderer, it is easy that liver is caused to damage when stirring liver using fan-shaped forceps, increases the dangerous risk of operation;It is practical
Novel (CN201020049682) proposes a kind of dedicated scatheless liver retractor for laparoscope, by the coupler body of hook retractor when use
The lower end that flexible pipe for medical purpose hooks into liver is put on, is lifted and is drawn, but the retractor is to utilize hook retractor during operation
It catches on liver to lift upwards, after the hook retractor known to (attached drawing 2) catches on liver, the tip of hook retractor is also hooked in liver simultaneously
, even if being cased with flexible pipe for medical purpose on coupler body, also easily liver is caused to damage since Liver on Judge Hardness is very tender in lower section；Utilize this
Retractor is performed the operation, and there are risks.
Utility model content
To solve the above-mentioned problems, the utility model proposes a kind of dedicated liver retractors of laparoscope.
The technical solution of the utility model is: a kind of dedicated liver retractor of laparoscope, including holding rod, hook retractor, top
Nematophore, the hook retractor are the coupler body that shape is in U-shape, and the coupler body of the hook retractor includes one section of straight bar section connecting with holding rod
First, with one section of straight bar section second connect of top nematophore, the arc section being connected between straight bar section first and straight bar section second, straight bar section first and
The upper end of straight bar section second parallel arrangement, holding rod is equipped with torus shank；The holding rod and straight bar section first junction
Angle is α, and straight bar section second and the angle for pushing up nematophore junction are β.
Preferably, 120 °≤α≤130 °, 140 °≤β≤150 °, the arc section radius of hook retractor is R, 3cm
≤R≤5cm。
Preferably, the holding rod, hook retractor, top nematophore are the identical cylindrical body medical titanium alloy in cross section.
The advantageous effects of the utility model are:
The hook retractor of the utility model is the coupler body that is in U-shape of shape, is inserted into liver using the coupler body of hook retractor U-shaped when operation
Dirty lower end holds up liver and performs the operation, and the coupler body of the hook retractor shape that is in U-shape will not scratch or puncture liver, avoids to liver
It causes to damage, reduces the dangerous risk of operation；Simultaneously the utility model production it is simple, easy to use, reduce manpower and
Operation cost, simplifying operation method reduces operating difficulty, has good social benefit.
Detailed description of the invention
Fig. 1 is the schematic view of the front view of the utility model；
Schematic view of the front view when Fig. 2 is the utility model operation；
Present invention looks up structural representation when Fig. 3 is the utility model operation；
In figure, 1. holding rods, 2. hook retractors, 201. straight bar section first, 202 straight bar section second, 203 arc sections, 3. top nematophores, 4.
Torus, 5. livers, 6. abdominal walls.
Specific embodiment
Embodiment one, referring to Figure of description (1-3), a kind of dedicated liver retractor of laparoscope, including holding rod, traction
Hook, top nematophore, the hook retractor is the coupler body that is in U-shape of shape, and the coupler body of the structure and the contact surface of liver are big, stirring and
It is more stable and firm when traction liver, liver will not be caused to damage, the coupler body of the hook retractor includes connecting with holding rod
One section of straight bar section first, one section of straight bar section second being connect with top nematophore, the arc section being connected between straight bar section first and straight bar section second,
Straight bar section first and straight bar section second are arranged in parallel, and the upper end of holding rod is equipped with torus shank, which is used to bind
Rope or bandage；The angle of the holding rod and straight bar section first junction is α, the folder of straight bar section second and top nematophore junction
Angle is β
120 °≤α≤130 °, 140 °≤β≤150 °, the arc section radius of hook retractor is R, 3cm≤R≤
5cm, above-mentioned angle composite human body abdominal cavity structure and liver structure, can be such that hook retractor is smoothly inserted into the human body, can also make to lead
It opens and is hooked in human body and smoothly can be stirred and be drawn, the radius of hook retractor can adapt to the trouble at different heights and age
Person performs the operation.
The holding rod, hook retractor, top nematophore are the identical cylindrical body medical titanium alloy in cross section.
The operating method of the utility model are as follows:
The top nematophore of draw hook lower end is inserted into the minimally invasive hole of abdomen by the holding rod for a. holding with a hand retractor,
The U-shaped portion of guidance draw hook enters intraperitoneal along minimally invasive hole；
B. draw hook enters behind abdominal cavity the position that liver is found by laparoscope, then rotates holding rod for draw hook
U-shaped portion is inserted into the bottom of liver, and the top nematophore of draw hook avoids thorn from encountering liver outwardly；
C. after the U-shaped portion of draw hook is completely inserted into the bottom of liver, operation holding rod holds up liver upwards, by liver
It is fitted in abdominal wall, the bottom of liver reveals at this time, operates convenient for subsequent abdominal operation；
D. it finally pinions torus with rope or medical bandage to fix retractor, the convenient bottom to liver carries out
Operation.
