The first opening in communication；The front end closing of described second secondary chamber, rear end and the second opening in communication on the body outer wall；
Described first secondary intracavitary, which is equipped with, to stretch out ontology and the biopsy device of retraction by the first opening manipulation；The ontology
LED illumination and CMOS photographic devices are embedded on the outer wall of front end；The LED illumination and CMOS photographic devices are by being set to described second
The signal wire of secondary intracavitary is simultaneously connected to external display equipment after second opening.
Further, the biopsy device includes the connecting rod of thin rod shape, and front end is equipped with sampling head, and rear end connects one
Button；The button is slide block type, can be snapped onto in first opening, and drive the sampling head to stretch out institute by sliding
State ontology or retraction；The sampling head is spoon shape, and size is adapted with the described first secondary lumen diameter, and with the connection boom end
Connection at an acute angle, can catch on biopsy, and be cut biopsy by shear action with ontology front end tube wall
Under.
Further, the rear end of the ontology, which is equipped with, can connect syringe with the matched connector of syringe
Carry out extraction or injection operation.
The beneficial effects of the utility model：
The utility model is designed reasonably, it is easy to use, it may be implemented to surgical procedures such as abdominocentesis and peritoneal biopsies
Visualization, to, greatly improve safety and the success rate of operation, and can simple flow, reduce the pain of patient.

Specific implementation mode
The utility model is further described with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2.
The compound visual abdominocentesis of one kind and peritoneal biopsy device, including acicular ontology 2.The ontology 2 is hollow
And both ends are open, inside includes the secondary 3 and second secondary chamber 12 of chamber of main chamber 13, first being arranged in an axially parallel mode along it.Main chamber 13
Connect with its rear end of the ontology 2, convenient for by the main chamber 13 from intraperitoneal extraction liquid or to intraperitoneal injection medicine
Water.
The front end and the front end of the ontology 2 of described first secondary chamber 3 penetrate through, rear end and first on 2 outer wall of the ontology
Opening 4 is connected.It is equipped with biopsy device in described first secondary chamber 3.The biopsy device 1 includes the connecting rod 1 of thin rod shape, front end
Equipped with sampling head 14, its rear end connects a button 5.The button 5 is slide block type, can be snapped onto in first opening 4, and
The sampling head 14 is driven to stretch out the ontology 2 or retract by sliding.The sampling head 14 be spoon shape, size with it is described
The caliber of first secondary chamber 3 is adapted, and with the connection at an acute angle of 1 end of the connecting rod, make the sampling head 14 be free to stretch
Go out or the described first secondary chamber 3 of retracting.Meanwhile the sampling head 14 can catch on the tissue of wanted biopsy, and returned in the connecting rod 1
During drawing, biopsy is cut by shear action with 2 front end tube wall of the ontology, then makes biopsy with taking
Sample head 14 is retracted together in the described first secondary chamber 3.
The front end closing of described second secondary chamber 12, rear end are connected with the second opening 7 on 2 outer wall of the ontology.It is described
2 front end of ontology abuts embedded LED illumination 10 and CMOS photographic devices 11 on the outer wall of the described second secondary chamber 12.Meanwhile described
Signal wire 9 is equipped in second mate's chamber 12.One end of the signal wire 9 connects the LED illumination 10 and CMOS photographic devices 11, the other end
It is connected to external display equipment 8 after second opening 7, keeps the LED illumination 10 controlled and luminous, and is made described
The image information that CMOS photographic devices 11 obtain is shown in time in display equipment 8.
Further, the rear end of the ontology 2 be equipped with can be with the matched connector 6 of syringe, can be with syringe
Extraction or injection operation are carried out after docking.
The application method of the utility model is：During ontology is pierced into abdominal cavity, LED illumination and CMOS camera shooting dresses are opened
It sets, by the Image Real-time Transmission in piercing process and includes being shown in equipment in computer etc., greatly facilitate the behaviour of doctor
Make, the accuracy and safety to improve operation create advantageous condition.When needing to carry out biopsy to peritoneal tissues, can push away
Dynamic button, makes intrinsic biopsy device move forward and the sampling head of its front end is made to stretch out ontology.Then, in visibility status
Under, by rotating ontology, sampling head is made to catch on the peritoneal tissues of selection.Then, reversed promoting button, makes sampling head with biopsy
Retraction of tissue.Can be when its retraction ontology when the biopsy of selection is larger, the tube wall part sharp with ontology front end
Cutting is formed, after tissue is cut in retraction ontology.Finally, biopsy device extracts abdominal cavity of patients with ontology, completes biopsy
Sampling.Due in the abdominocentesis and peritoneal biopsy process, often also needing to extract intraperitoneal liquid, or, it needs to abdomen
Intracavitary administration liquid medicine then connects the syringe on the connector of ontology rear end, is not necessarily to the separately operations such as puncture, not only pole
Big facilitates surgical procedure, and also reduces the pain of patient.
The parts not involved in the utility model is the same as those in the prior art or can be realized by using the prior art.
