Abstract
A laparoscopic busing re-entry guide is composed of a guide pipe (1), a guide head (2) which is arranged at the front end of the guide pipe (1) and a valve body (3) at the back end. A valve switch is arranged on the valve body (3). The guide head (2) of the utility model is conical and easily passes through the original trauma channel of the abdominal wall without the damage of abdominal viscera, a laparoscopic busing extends the guide pipe for slowly propulsion after gas filling and establishing aeroperitonia, thereby avoiding the possible injuries of internal organs when the laparoscopic busing is directly inserted. By adopting the re-entry guide for carrying out the laparoscopic operation, the laparoscopic busing can be guided to carry out safe and effective re-entry. The abdominal viscera can not be easily damaged, the trauma face is reduced, the operation time is shortened, the laparoscopic operation is more secure, rapid and reliable, the postoperative recovery is fast, and the clinical effects are better.
Description
Technical field
This utility model relates to the surgery laparoscopic surgical instruments, and a laparoscopic cannula (trocar sheath) reenters guide specifically.Be applicable to the guiding that reenters of laparoscopic surgery middle sleeve, also can be used as and dial rod and suction aspirator tip use.
Background technology
At first need during the laparoscopically surgical operation operation to abdominal cavity filling CO 2 gas abdominal wall to be raised, space enlargement in the abdomen could be implemented operation then.In the operation, no matter laparoscopic cannula is according to operation needs taking-ups (particularly single hole method laparoscopic surgery) or deviates from voluntarily for a certain reason, all needs once more laparoscopic cannula is inserted intraperitoneal, just can carry out next step operation technique.When sleeve pipe is got after (taking off) go out, fill at Intraabdominal carbon dioxide and will discharge from the puncturing hole on the abdominal cavity, cause pneumoperitoneum to disappear, abdominal wall is subsided, when once more laparoscopic cannula being inserted the abdominal cavity, following several method is generally arranged, the one, carry it into from the puncture of original road once more with sharp puncture awl, but may stab abdominal viscera; The 2nd, bring into dialling rod, but because group nose circle is blunt, contraction of original road and level are more on the stomach wall, enter very difficult; The 3rd, enlarge, cut along the layering of original road, direct-view is inserted sleeve pipe down, but relatively wastes time and energy, simultaneously, more than three kinds of methods all exist the prolongation operating time, increase operation risk and increase the problem of patient's misery.
Summary of the invention
The purpose of this utility model provides a kind of laparoscopic cannula quick and easy, safe in utilization and reenters guide.
This utility model is achieved in that it is made up of guiding tube, seeker and valve body, and described guiding tube front end is equipped with seeker, and seeker is a cone, and cone is provided with through hole.The rear end of guiding tube is provided with valve body, and valve body is provided with valve switch.
Adopt this utility model to carry out laparoscopic surgery, the guide abdominal mirror is telescopic safely and effectively inserts once more.The easy damaged abdominal viscera has not reduced wound face, shortens operating time, makes abdominal operation safer, rapid, reliable, has obtained clinical effectiveness preferably.
Description of drawings
Fig. 1 is this utility model structural representation.
Fig. 2 is Fig. 1 seeker (2) partial view.
Fig. 3 is Fig. 1 valve body (3) partial view.
The specific embodiment
This utility model is made by inferior light rustless steel, and 400 millimeters of total lengths are made up of guiding tube, seeker and valve body.30 millimeters of guiding head lengths, hollow for coniform, 1 millimeter of wall thickness, 5 millimeters of tip diameter, 10 millimeters of bottoms, uniform 32 millimeters apertures in the middle of the cone, seeker 2 and guiding tube 1 are threaded by 5 millimeters.10 millimeters of guiding tube 1 diameters, long 340 millimeters, 1 millimeter of wall thickness.30 millimeters of valve body 3 length are threaded with guiding tube 1.In the laparoscopic surgery, when laparoscopic cannula is inserted once more, earlier this utility model is linked to each other with the pneumoperitoneum apparatus airway, be nested into then in the laparoscopic cannula, cone segments of the present utility model in laparoscopic cannula comes off the wound road insertion abdomen of locating, is opened the inflation of pneumoperitoneum apparatus switch, slowly push laparoscopic cannula in the abdomen after setting up pneumoperitoneum, finish inserting once more of laparoscopic cannula, close the pneumoperitoneum apparatus switch, this introducer is withdrawn from.
This utility model clinical practice, effective.Because this utility model seeker is conical, is easy to can not injure abdominal viscera by the original road of stomach wall, after setting up pneumoperitoneum, inflation again laparoscopic cannula is pushed, and avoided laparoscopic cannula to enter the visceral injury that may cause.Clinical practice proves that this apparatus application safety, quick, effective is particularly suitable for single hole method laparoscopic surgery.This utility model also can be used as group rod and suction aspirator tip use in laparoscopic surgery in addition.
