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 inflation hands rake drag hook of Minimally Invasive Surgery

The drag hook that in inner chamber, uses when the present invention relates to Minimally Invasive Surgery.

In the existing Wicresoft in the surgical cavity,, need open a plurality of holes like this and finish the work because the used medical apparatus and instruments of its operation all will enter inner chamber less than one centimetre sheath from diameter; Sometimes, open a plurality of holes and still be difficult to satisfy requirements of operation, make patient adopt out big wound area to finish operation, bring big grieved to patient.

Order of the present invention just provides a kind of simple to operate, but the large tracts of land rake is opened the inflation hands rake drag hook of the Minimally Invasive Surgery of organ.

In order to reach above purpose, the operation principle of the inflation hands rake drag hook of Minimally Invasive Surgery of the present invention is: will be positioned on the shell of check valve less than the inflation hands rake of being made by soft material of inflation, it is put into patient's inner chamber from trocar, the trocar outside is stayed at the check valve rear portion, the blowhole of high pressure gas from check valve is pressed into the inflation hands rake, inflation hands rake is opened at patient's inner chamber, form a high hydraulic support, the inflation hands 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 trocar, enter intraperitoneal from trocar, insert buckling on the inflation hands rake with pliers, by the position of pliers control inflation hands rake, 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 inflation hands rake drag hook of Minimally Invasive Surgery of the present invention is made up of inflation hands rake, check valve and pliers, inflation hands rake is harrowed plate, is buckled with the tunnel and form by the inflation hands, buckle with the tunnel and be glued on the inflation hands rake plate, the inlet end of inflation hands rake plate is positioned on the check valve.During use, air emptying with inflation hands rake plate, cylindric its coiled, put into inner chamber the hole of trocar on being positioned on wound, the check valve other end is stayed the trocar outer end, it is human vitronectin, gases at high pressure are compressed into from check valve inlet, and gases at high pressure enter inflation hands rake plate by check valve, will inflate hands rake plate and open, regain high-pressure air pipe, check valve blocks air inlet automatically, and check valve is pushed intraperitoneal from the hole of trocar, and the reuse pliers passes from the hole of trocar and enters the abdominal cavity, the pliers front end penetrate buckle with the tunnel in, clamp then and buckle.At this moment can be according to concrete surgery situation, outside the patient body, the operation pliers makes inflation hands rake plate contact with 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 mouth less in addition, will be reduced patient's actual bodily harm.The present invention can also finish the patient's operation that is not suitable for Minimally Invasive Surgery of existing opening, and these patients are carried out Minimally Invasive Surgery.

Be described further with the inflation hands rake drag hook of drawings and Examples below Minimally Invasive Surgery of the present invention.

Accompanying drawing 1 is the inflation hands rake drag hook figure of the 1st embodiment local form of Minimally Invasive Surgery of the present invention.

Accompanying drawing 2 is inflation hands rake drag hook the 1st embodiment accompanying drawing 1 cutaway view of Minimally Invasive Surgery of the present invention.

Accompanying drawing 3 is inflation hands rake drag hook the 1st embodiment broken section enlarged drawing of Minimally Invasive Surgery of the present invention.

Accompanying drawing 4 is inflation hands rake drag hook the 2nd embodiment partial sectional view of Minimally Invasive Surgery of the present invention.

Accompanying drawing 5 is that the inflation hands of Minimally Invasive Surgery of the present invention is harrowed drag hook the 2nd embodiment accompanying drawing 4 to view.

To the 1st embodiment shown in the accompanying drawing 3, the inflation hands of Minimally Invasive Surgery of the present invention rake drag hook is by inflation hands rake (1) at accompanying drawing 1, and check valve (2) and pliers (3) are formed; Inflation hands rake (1) by hands rake plate (1-1), buckle (1-2) and tunnel (1-3) forms, buckling (1-2) and tunnel (1-3) is glued on the hands rake plate (1-1), check valve (2) is made up of shell (2-1), bolt (2-2), spring (2-3) and bead (2-4), bead (2-4) and spring (2-3) are placed in the endoporus of shell (2-1), bolt (2-2) is positioned in the shell (2-1), have the hole in the bolt (2-2), spring (2-3) is a volute spring.Check valve (2) is harrowed the mutual gluing of plate (1-1) together by C position and hands.In the hole of high-pressure air pipe insertion shell (2-1), bead (2-4) is open, and high pressure gas can enter from the aperture the bolt (2-2) in the hands rake plate (1-1).After using, check valve (2) is put into the hole of trocar, with the air inlet of trachea insert division shell (2-1), the inside gases at high pressure are taken out check valve (2) and inflation hands rake (1) by emitting in the trachea again.

To the 2nd embodiment shown in the accompanying drawing 5, it and the 1st embodiment difference are at accompanying drawing 4: check valve (2) is by shell (2-1) and seal (2-2) and form, and sealing (2-2) is a half round post.Two resilient cylindricals are glued in the cylindrical hole of shell (2-1), want aerating and when venting, insert in the middle of sealing (2-2) with tracheole from two, draw back from this after finishing, two resilient seals (2-2) mutual extrusion guarantees that the gas of within and without can not pass in and out together.Thereby reach and the 1st embodiment same effect.
