At the deficiency of this operation in the past, a kind of micro-wound surgical operation---laparoscopic surgery has appearred.So-called peritoneoscope is a kind of apparatus that has minisize pick-up head, and laparoscopic surgery is exactly a hands art of utilizing peritoneoscope and related equipment thereof to carry out; Use cold light source that illumination is provided, (diameter is 3～10mm) insertion intraperitoneal with the peritoneoscope camera lens, utilization digital camera technology make the peritoneoscope lens shooting to image conduct to back level signal processing system by optical fibers, and be presented on the dedicated monitor in real time.The doctor carries out analytical judgment by the image of shown patient's organ different angles on the monitor screen to patient's the state of an illness then, and uses special laparoscopic instrument to undergo surgery.It is little that laparoscopic surgery has wound, and otch is attractive in appearance, and patient recovers advantage such as fast.

Existing laparoscopic surgery all needs to use peritoneoscope puncture casing (Trocar) in operating process, claim bent card again.Sleeve pipe generally is made of the trocar and casing seat, during use, the trocar is pierced through stomach wall, extracts nook closing member then, and sleeve pipe is stayed stomach wall, as the passage in apparatus turnover abdominal cavity in the operation.Yet the puncture casing that uses all is the single channel structure at present, promptly has only a trocar.In operation, in the time of need observing, cut, separate or place operation such as ureteral catheter, double J pipe simultaneously, the sleeve pipe of single channel structure just can't be satisfied the demand simultaneously, must increase the sleeve pipe otch of respective numbers in patients abdomen, to satisfy the operation demand.Such operation more complicated, quick inadequately, and patient's health also increased damage.

Summary of the invention

This utility model purpose provides a kind of peritoneoscope puncture casing, by improvement to structure, make that both operating theater instruments can be entered the abdominal cavity in operation is carried out operates, also flexible devices such as double J pipe, ureteral catheter can be placed into intraperitoneal, do not need to offer otch in addition, simple and efficient to handle.

For achieving the above object, the technical solution adopted in the utility model is: a kind of peritoneoscope puncture casing, comprise that mainly a hollow tubular master trocar constitutes, described main trocar end is provided with main casing seat, described main casing seat end face offers through hole, and described main casing seat side is provided with the pneumoperitoneum interface tube, and described main trocar side is fixedly connected with the trocar on one side, described other trocar length is not more than the main trocar, and described other trocar end is provided with other casing seat.

In the technique scheme, carrying out laparoscopic surgery, at first need be in hole of abdominal incision, the main trocar of peritoneoscope puncture casing is inserted intraperitoneal, main casing seat is exposed to outside the abdominal cavity, owing to offer through hole on the main casing seat end face, the related equipment that uses in the operation can enter in the puncture casing by through hole, and extend into intraperitoneal by the main trocar always, the processing that promptly can undergo surgery, main casing seat side is provided with the pneumoperitoneum interface tube, is connected with barometric control unit in operation, be used to regulate the intraperitoneal gas pressure, guarantee the safety of operation.Because the other fixedly connected one side of main trocar trocar, thereby in operation, need to place flexible flexible devices such as Intraabdominal ureteral catheter, double J pipe, laser fiber and can directly place into intraperitoneal by other casing seat and along the other trocar.Ureteral catheter is used for the external drainage urine; Double J pipe is to carry out behind the operation on ureter, connect between kidney and the bladder in drainage of urine, prevent from because two ends all are " J " type, thereby to be called double J pipe by urine leakage; Laser fiber is used to carry out the laser surgery excision.Flexible devices such as double J pipe can directly be placed into intraperitoneal by other sleeve pipe, and are simple and efficient to handle, and need not to open in addition otch, also less to the patient body infringement.

Further technical scheme constitutes an acute angle between the terminal nearly main casing seat place's bending of the described other trocar and the main trocar.Because the existence of main casing seat, thereby the setting of the terminal acuter angles of the other trocar, can be conveniently connect other casing seat in that the other trocar is terminal, and other sleeve pipe is used for by flexible device, thereby the bending setting of acuter angles does not influence passing through of device.

Because the technique scheme utilization, the advantage that this utility model compared with prior art has is:

1, this utility model is by being fixedly connected with the trocar on one side at main trocar side, described other trocar end is connected with casing seat on one side, make in operative process, can pass through operating theater instruments in the main sleeve pipe, can be in the other sleeve pipe simultaneously by flexible devices such as double J pipes, simple and efficient to handle, and need not to open in addition otch, less to the patient body infringement.

2. this utility model is simple in structure, and is cheap for manufacturing cost, is fit to promote the use of.
