Abstract
The invention discloses an inflatable hand rake hook for a minimally invasive surgery, which consists of an inflatable hand rake (1), a check valve (2) and a pair of forceps (3), wherein the inflatable hand rake (1) is arranged on the check valve (2). After a hand rake plate (1-1) enters an abdominal cavity from a trocar (Trocar), high pressure gas is introduced into the inflatable hand rake (1) from the check valve (2), so that the generated pressure is higher and harder, and the pair of forceps (3) is sleeved inside the inflatable hand rake (1) to open, press and support each organ. Only a small hole is formed, and the working face in the abdominal cavity is large; therefore, the operation is convenient.
Description
The drag hook that uses in inner chamber when the present invention relates to Minimally Invasive Surgery.
In existing Wicresoft internal cavity operation, because its operation medical apparatus and instruments used all will enter inner chamber less than the sheath of a centimetre from diameter, need open so a plurality of holes and finish the work; Sometimes, open a plurality of holes and still be difficult to satisfy requirements of operation, make patient adopt out large wound area to complete operation, bring the larger pain of injury to patient.
Order of the present invention just is to provide a kind of simple to operate, but the large tracts of land rake is opened the Inflatable hand rake hook of the Minimally Invasive Surgery of organ.
in order to reach above purpose, the operation principle of the Inflatable hand rake hook of Minimally Invasive Surgery of the present invention is: will be positioned on the shell of check valve less than the Inflatable hand rake of being made by soft material of inflation, it is put into patient's inner chamber from sheath, the sheath outside is stayed at the check valve rear portion, the blowhole of high pressure gas from check valve is pressed into Inflatable hand rake, Inflatable hand rake is opened at patient's inner chamber, form a high hydraulic support, the Inflatable hand rake plate that certain degree of hardness is arranged, take away gas tube, check valve is blocked pore, the check valve part is all put into human abdominal cavity from the hole of sheath, enter intraperitoneal with pliers from sheath, insert buckling on Inflatable hand rake, controlled the position of Inflatable hand rake by pliers, just a large amount of luminal organ of blocking surgery location can be pushed down and pushed aside.According to operation principle, its technical scheme is: the Inflatable hand rake hook of Minimally Invasive Surgery of the present invention is comprised of Inflatable hand rake, check valve and pliers, Inflatable hand rake by the Inflatable hand rake plate, buckle with the tunnel and form, buckle with the tunnel and be glued on the Inflatable hand rake plate, the inlet end of Inflatable hand rake plate is positioned on check valve.During use, air emptying with the Inflatable hand rake plate, it is coiled into cylindric, put into inner chamber the hole of the sheath on being positioned on wound, the check valve other end is stayed the sheath outer end, it is human vitronectin, gases at high pressure are compressed into from check valve inlet, and gases at high pressure enter the Inflatable hand rake plate by check valve, and the Inflatable hand rake plate is opened, regain high-pressure air pipe, check valve blocks air inlet automatically, and check valve is pushed intraperitoneal from the hole of sheath, then passes from the hole of sheath with pliers and enter the abdominal cavity, the pliers front end penetrate buckle with the tunnel in, then clamp and buckle.At this moment can be according to concrete surgery situation, outside the patient body, the operation pliers makes the Inflatable hand rake plate contact to relevant organ by the doctor.
After adopting above method, the doctor need not out porous and just large-area organ can be pushed aside in minimal invasive surgical procedures, push down or jack-up, not only makes doctor's facilitating operation, and is simple to operate simultaneously, can start less mouth in addition, will be reduced patient's actual bodily harm.The present invention can also complete the patient's operation that is not suitable for Minimally Invasive Surgery of existing opening, and these patients are carried out Minimally Invasive Surgery.
The below is described further with the Inflatable hand rake hook of drawings and Examples to Minimally Invasive Surgery of the present invention.
Accompanying drawing 1 is Inflatable hand rake hook the 1st embodiment figure of local form of Minimally Invasive Surgery of the present invention.
Accompanying drawing 2 is Inflatable hand rake hook the 1st embodiment accompanying drawing 1 cutaway view of Minimally Invasive Surgery of the present invention.
Accompanying drawing 3 is Inflatable hand rake hook the 1st embodiment broken section enlarged drawing of Minimally Invasive Surgery of the present invention.
Accompanying drawing 4 is Inflatable hand rake hook the 2nd embodiment partial sectional view of Minimally Invasive Surgery of the present invention.
Accompanying drawing 5 is that Inflatable hand rake hook the 2nd embodiment accompanying drawing 4 of Minimally Invasive Surgery of the present invention is to view.
To the 1st embodiment shown in accompanying drawing 3, the Inflatable hand rake hook of Minimally Invasive Surgery of the present invention is by Inflatable hand rake (1) at accompanying drawing 1, and check valve (2) and pliers (3) form; Inflatable hand rake (1) is by hands rake plate (1-1), buckling (1-2) and tunnel (1-3) forms, buckling (1-2) and tunnel (1-3) is glued on hands rake plate (1-1), check valve (2) is by shell (2-1), bolt (2-2), spring (2-3) and bead (2-4) form, bead (2-4) and spring (2-3) are placed in the endoporus of shell (2-1), bolt (2-2) is positioned in shell (2-1), have the hole in bolt (2-2), spring (2-3) is volute spring.Check valve (2) is mutually cemented together by C position and hands rake plate (1-1).In the hole of high-pressure air pipe inserting bolt (2-2), bead (2-4) is open, and high pressure gas can enter in hands rake plate (1-1) by the aperture from bolt (2-2).After using, check valve (2) is put into the hole of sheath, in the hole with trachea inserting bolt (2-2), the inside gases at high pressure are by emitting in trachea, then check valve (2) and Inflatable hand rake (1) are taken out.
To the 2nd embodiment shown in accompanying drawing 5, it and the 1st embodiment difference are at accompanying drawing 4: check valve (2) is comprised of shell (2-1) and sealing (2-2), and sealing (2-2) is a half round post.The closure of two resilient half outside cylinder (2-2) is glued in the cylindrical hole of shell (2-1), when wanting aerating and venting, insert in the middle of two sealings (2-2) with tracheole, draw back from this after completing, two resilient seals (2-2) press together mutually, guarantee that the gas of within and without can not pass in and out.Thereby reach and the 1st embodiment same effect.
