Abstract
The utility model provides a laparoscopic surgery's disposable pneumoperitoneum needle, include needle file, spring holder, valve, spring, puncture cannula, wear spunlace, needle tubing, syringe needle, puncture cannula's front end with wear spunlace and become integrative, it is sharp -pointed to wear spunlace, puncture cannula's rear end is fixed with the needle file, the front end of needle tubing is convex syringe needle, and the front end of needle tubing is opened has the gas outlet, and the rear end of needle tubing is fixed with the spring holder, the needle tubing is located puncture cannula, and spunlace is worn out to wear by the syringe needle, the one end of spring is fixed in the needle file, and the other end is fixed with the spring holder, the valve pass through the connecting pipe and be connected with the rear end of needle file. The utility model has the advantages of reasonable design, pneumoperitoneum is effectual, under the effect of spring and convex syringe needle, wears spunlace and can not harm internal tissue, and it is safer to perform the operation.
Description
Technical field
This utility model relates to a kind of disposable veress needle of laparoscopic surgery, belongs to technical field of medical instruments.
Background technology
In human abdominal cavity in Wicresoft's laparoscopic surgery, need to carry out CO2 pneumoperitonium in human body, make there is certain space in human abdominal cavity, operation can be carried out smoothly.Prior art also has veress needle, but veress needle is the repeat surgery application apparatus that metal material makes, the similar puncture cover with needle tubing, directly be connected with carbon dioxide air source after penetrating human abdominal cavity, carry out human abdominal cavity operation pneumoperitoneum, its hetero-organization of puncturing head meeting prick into human body intraperitoneal, structure simple bushings easily blocks; Also exempt from pneumoperitoneum medical surgical instrument, be generally applied to the minor operation of the joint tissue of human body; Meet unexpectedly desirable surgical effect.
Utility model content
Technical problem to be solved in the utility model overcomes above-mentioned deficiency existing in prior art, and provide a kind of reasonable in design, and pneumoperitoneum is effective, and puncturing head can not damage the disposable veress needle of the laparoscopic surgery of in-vivo tissue.
This utility model solves the problems of the technologies described above adopted technical scheme: a kind of disposable veress needle of laparoscopic surgery, it is characterized in that: it comprises needle stand, spring base, valve, spring, puncture casing, puncturing head, needle tubing, syringe needle, front end and the puncturing head of described puncture casing are integral, puncturing head is sharp-pointed, and rear end and the needle stand of puncture casing are fixed; The front end of described needle tubing is the syringe needle of circular arc, and the front end of needle tubing has gas outlet, and rear end and the spring base of needle tubing are fixed; Needle tubing is positioned at puncture casing, and syringe needle passes puncturing head; One end of described spring is fixed in needle stand, and the other end and spring base are fixed; Described valve is connected with the rear end of needle stand by connection tube.
The pneumoperitoneum passage interconnected is provided with in needle tubing described in the utility model, needle stand and connection tube.
Compared with prior art, have following positive effect: reasonable in design, pneumoperitoneum is effective for this utility model, and under the effect of spring and circular arc syringe needle, puncturing head can not damage in-vivo tissue, performs the operation safer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail.
Embodiment:
See Fig. 1 ~ Fig. 2, the present embodiment comprises needle stand 1, spring base 2, valve 3, spring 4, puncture casing 5, puncturing head 6, needle tubing 7, syringe needle 9, front end and the puncturing head 6 of described puncture casing 5 are integral, and puncturing head 6 is sharp-pointed, and rear end and the needle stand 1 of puncture casing 5 are fixed; The front end of described needle tubing 7 is the syringe needle 9 of circular arc, and the front end of needle tubing 7 has gas outlet 8, and rear end and the spring base 2 of needle tubing 7 are fixed; Needle tubing 7 is positioned at puncture casing 5, and syringe needle 9 passes puncturing head 6; One end of described spring 4 is fixed in needle stand 1, and the other end and spring base 2 are fixed; Described valve 3 is connected with the rear end of needle stand 1 by connection tube 10.
In the present embodiment, in needle tubing 7, needle stand 1 and connection tube, be provided with the pneumoperitoneum passage interconnected.
In the present embodiment, the sharp human body that can thrust of puncturing head 6 enters abdominal cavity, and needle tubing 7 can slide in puncture cover, and spring 4 withstands needle tubing 7 and has tension force in needle stand 1.
During use, when puncturing head 6 is when thrusting human abdomen, the syringe needle 9 of circular arc slides backward under counteracting force, and spring 4 compresses; When puncture casing 5 penetrates in human abdominal cavity, needle tubing 7 resets under the effect of spring 4, and the syringe needle 9 of circular arc is given prominence to forward; Syringe needle 9 can in human abdominal cavity voluntary activity, effectively can prevent puncturing head 6 from damaging its hetero-organization in human body, ensure carrying out smoothly of operation.When syringe needle 9 moves to assigned address, can carry out pneumoperitoneum by valve 3 and pneumoperitoneum passage to intraperitoneal, gas enters from valve 3, after pneumoperitoneum passage, enters abdominal cavity from gas outlet 8.
Veress needle described in the utility model is disposable surgical application, avoids the cross infection of applying of performing the operation.
In addition, it should be noted that, the specific embodiment described in this description, as long as the undeclared concrete shape of its part and size, then this part can for any shape and size adapted with its structure; Meanwhile, the title that part is got also can be different.All equivalences of doing according to structure, feature and the principle described in this utility model inventional idea or simple change, be included in the protection domain of this utility model patent.
