Abstract
The utility model relates to a medical device, in particular to a working cannula for laparoscopic surgery. The working cannula for laparoscopic surgery is provided with the working cannula, wherein an abdominal cavity tube is arranged in the working cannula, an inner positioning gas bag and an outer positioning gas bag are respectively arranged on the outer wall of the working cannula, an annulated column-shaped inner gas bag is arranged in the working cannula, the inner gas bag is communicated with the inner positioning gas bag and the outer positioning gas bag, inflation tubes are arranged on the inner gas bag, the inner positioning gas bag or/and the outer positioning gas bag, the inner gas bag is communicated with the inner positioning gas bag and the outer positioning gas bag via gas transmission tubes, and a mirror wiper is arranged at the front end of the working cannula. When the working cannula is used, the working cannula is firstly placed in the abdominal wall for enabling the inner and the outer positioning gas bags to be positioned inside and outside the abdominal wall, after inflation via the inflation tubes, the interior of the working cannula is closed, and the working cannula is further fixed. A surgical doctor can conveniently enable a laparoscope, a surgical clamp and other surgical instruments to pass a working channel for performing surgical operation, and the working cannula has the advantages of simplifying the surgical operation, reducing the number of surgical staff, being convenient to operate, being firm and reliable in connection and the like and further provides convenience for single-incision laparoscopic surgery.
Description
Technical field
The present invention relates to technical field of medical instruments, the laparoscopic surgery working column that specifically a kind of Minimally Invasive Surgery uses.
Background technology
As everyone knows, because advantages such as wound little, treatment time weak point, patient's light pain, the application of the Minimally Invasive Surgery under the peritoneoscope cooperation more and more widely; Peritoneoscope working column wherein is to insert in the human body, and as the passage through operating theater instruments, the doctor can send into peritoneoscope and operating theater instruments in the human body by working column and realizes the diagnosis and the operative treatment of disease; Existing peritoneoscope working column is tubular for always, and it does not have fixture, in operation process, is easy in human body, deviate from; Need place again; Delayed the operation process, Chinese patent discloses a kind of multi-channel soft abdominal wall working window of the applicant's invention, and the patent No. is 2009200185089; It is provided with the column air bag; The column air bag is provided with gas tube and at least two service aisles, and service aisle is sealed by gas pressure, the service aisle drawbacks such as causing gas leakage that is distorted during use.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, a kind of laparoscopic surgery working column easy to operate, safe in utilization is provided.
The present invention can reach through following measure:
A kind of laparoscopic surgery working column; Be provided with working column, be provided with the abdominal cavity pipe in the working column, positioning gasbag and outside fix air bag in being respectively equipped with on the outer wall of working column; It is characterized in that being provided with in the working column interior air bag; Interior air bag is the gas column of a band central through hole, and interior air bag is connected with interior positioning gasbag and outside fix air bag, interior air bag, interior positioning gasbag and (or) the outside fix air bag is provided with gas tube.
Air bag was connected through aerophobic tube with interior positioning gasbag and outside fix air bag in this utility model was described; To dredge the gas between interior air bag, interior positioning gasbag and outside fix air bag, prevent that the pressure of certain air bag is excessive or too small, for example the air pressure of air bag is excessive in the working column; Safety with insertion that influences operating theater instruments and interior air bag; If but the pressure of interior air bag is too small,, influence the operation process with the sealing that influences working column.
The present invention can be provided with mirror at the working column front end and wipe, and mirror is wiped and generally is located at the working column front bulkhead, with laparoscopically camera lens convenient for cleaning, reduces operating procedure, shortens operating time.
Interior positioning gasbag described in the present invention and outside fix air bag are in the form of a ring or several monomer air bags; Interior positioning gasbag and outside fix air bag are the air ring formula respectively; Interior positioning gasbag and outside fix air bag are respectively equipped with at least two monomer air bags; To be that working column is fixed better, improve safety, the shortening operating time of operation.
When the present invention uses, earlier working column is inserted stomach wall, inside and outside positioning gasbag is positioned at inside and outside the stomach wall, through the inner and steady job sleeve pipe of gas tube inflation rear enclosed working column.Operative doctor can be easily be patient's operation that undergos surgery with operating theater instruments such as peritoneoscope, operating forcepies through service aisle; Has the simplification operation technique; Reduce advantages such as surgical staff, easy to operate, firm and reliable connection, also facilitate for single otch laparoscopic surgery.

The specific embodiment
Below in conjunction with embodiment the present invention is further described.
As shown in the figure, a kind of laparoscopic surgery working column is provided with working column 1, is provided with abdominal cavity pipe 7 in the working column 1; Abdominal cavity pipe 7 is arranged in the working column 1, also can be arranged in the tube wall of working column 1 positioning gasbag 2 and outside fix air bag 3 in being respectively equipped with on the outer wall of working column; Interior positioning gasbag 2 and outside fix air bag 3 to be that working column positions better, improve safety, the shortening operating time of operation in the form of a ring; Air bag 4 in being provided with in the working column 1, interior air bag 4 are the gas column of a band central through hole, expand in interior air bag 4 inflation backs; With its centre bore sealing (gas-tight), operating theater instruments is passed through the centre bore of interior air bag 4 into and out of patient's intraperitoneal, and annular air-pocket 4 is column; To improve its sealing to surgical instrument, interior air bag 4 is connected with outside fix air bag 3 with interior positioning gasbag 2, and interior air bag 4 generally is connected through aerophobic tube with outside fix air bag 3 with interior positioning gasbag 2; Aerophobic tube generally is located in the tube wall of working column 1, and the gas with 3 in air bag 4 in dredging, interior positioning gasbag 2 and outside fix air bag prevents that the pressure of certain air bag is excessive or too small; If the air pressure of interior air bag is excessive, will be through aerophobic tube decompression, air bag 4 explosions in preventing; If the pressure of interior air bag 4 is too small, will avoid influencing the sealing and the surgical effect of working column through the aerophobic tube supercharging.Interior air bag 4, interior positioning gasbag 2 or outside fix air bag 3 are provided with gas tube 5, in addition, can be provided with mirror at working column 1 front end and wipe 6; Mirror is wiped 6 and generally is located at working column 1 front bulkhead, with laparoscopically camera lens convenient for cleaning, reduces operating procedure, shortens operating time; When the present invention uses; Earlier working column is inserted stomach wall, inside and outside positioning gasbag is positioned at inside and outside the stomach wall, through the inner and steady job sleeve pipe of gas tube inflation rear enclosed working column.Operative doctor can be easily be patient's operation that undergos surgery with operating theater instruments such as peritoneoscope, operating forcepies through service aisle; Has the simplification operation technique; Reduce advantages such as surgical staff, easy to operate, firm and reliable connection, minimizing patient operative incision, also facilitate for single otch laparoscopic surgery.
