Description
technical field
This utility model relates to a kind of suction veress needle, belongs to medical instruments field.
Background technology
Veress needle is a kind of surgical operating instrument, and its main uses is to carry gas to set up pneumoperitoneum for puncturing into the backward intraperitoneal in abdominal cavity in laparoscopic surgery, for the enforcement of subsequent procedures provides basis.Suction pipe is to rinse during for endoscopic surgery, attract, and realizes the i.e. suction of i.e. punching in art simultaneously, removes rapidly blood stains in operation process, gas, water etc., facilitates operation technique.
Utility model content
Utility model object: technical problem to be solved in the utility model is to provide a kind of suction function that both had, can also carry gas to set up the suction veress needle of pneumoperitoneum to intraperitoneal.
Utility model content: for solving the problems of the technologies described above, the technological means that this utility model adopts is:
A kind of suction veress needle, comprise suction pipe, puncture needle, air injection pipe and hands handle, described handle is divided into the front end being interconnected, middle-end and rear end, in described handle middle-end and rear end, be cavity structure, in described cavity structure, be equipped with spring, described suction pipe front end is provided with suction hole, its rear end is provided with spacing flange, described suction pipe cooperatively interacts by spacing flange and described handle front end, and elastic in handle front end by spring I, described puncture needle is positioned at suction pipe, described puncture needle rear end is fixed in handle, described air injection pipe front end is closed round end, and its front end side wall is provided with injecting hole, described air injection pipe rear end is provided with spacing flange, described air injection pipe is positioned at puncture needle, before it, rear end is all stretched out outside puncture needle, and its rear end is fixedly connected with one end of spring II by described spacing flange, the other end of described spring II is fixed in handle, described handle middle-end is provided with to rinse and attracts interface, described handle rear end is provided with gas injection interface, described gas injection interface is communicated with described air injection pipe.
Wherein, described suction pipe front end is provided with suction hole, and described suction hole is divided into main suction hole and side blow sucker.
Beneficial effect: than prior art, suction veress needle of the present utility model can carry gas to set up pneumoperitoneum to intraperitoneal, also there is suction function, therefore this utility model can be realized and after pneumoperitoneum has been set up, in operation process, carry out I & A, and can continue the pressure that gas injection maintains pneumoperitoneum simultaneously, than suction pipe or the veress needle of simple function, suction veress needle of the present utility model is rational in infrastructure, complete function.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, this utility model content is further described.
As shown in Fig. 1 ~ 6, suction veress needle of the present utility model, comprise suction pipe 9, puncture needle 6, air injection pipe 1 and hands handle, handle is divided into the handle front end 13 being interconnected, middle-end 16 and rear end 18, in handle middle-end 16 and rear end 18, be cavity structure, in cavity structure, be equipped with spring, suction pipe 9 front ends are provided with suction hole, its rear end is provided with spacing flange 11, suction pipe 9 cooperatively interacts with handle front end 13 by spacing flange 11, and can be handle front end 13 interior elastic (suction pipe 9 be fixedly connected with spring I15) by spring I15, puncture needle 6 is positioned at suction pipe 9, and puncture needle 6 front ends are syringe needle part 7, during normal condition, 7 contractings of syringe needle part are in suction pipe 9, puncture needle 6 rear ends are fixed in handle middle-end 16, air injection pipe 1 front end is closed round end 3, and its front end side wall is provided with injecting hole 2, the cross section of injecting hole 2 is U-shaped, and injecting hole 2 adopts and is symmetrical arranged, thereby make gas injection effect more even, air injection pipe 1 rear end is provided with spacing flange 4, air injection pipe 1 is positioned at puncture needle 6, before it, all stretch out outside puncture needle 6 rear end, and its rear end is fixedly connected with one end of spring II17 by spacing flange 4, the other end of spring II17 is fixed in handle rear end 18, air injection pipe 1 can be interior elastic at handle rear end 18, handle middle-end 16 is provided with interface I19, interface I19 attracts interface for rinsing, handle rear end 18 is provided with interface II22, interface II22 is gas injection interface, it is communicated with air injection pipe 1.Suction is managed 9 and is provided with suction hole, and suction hole is divided into main suction hole 12 and side blow sucker 10, and side blow sucker 10 is radial distribution, is 1 row or many row's arrangements, thereby makes to suction better effects if.
While adopting this utility model suction veress needle to implement puncture, suction pipe 9 is blocked and withdraws by epidermis, spring I15 compression, air injection pipe 1 meets with obstruction and also withdraws simultaneously, spring II17 also compresses, air injection pipe 1 contracts in puncture needle 6, puncture needle 6(syringe needle part 7) to stretch out outside suction pipe 9 and puncture, air injection pipe 1 contracts in puncture needle 6 and follows puncture needle 6 and puncture and enter abdominal cavity together; Enter behind abdominal cavity, air injection pipe 1 ejects from puncture needle 6, because air injection pipe 1 front end adopts closed round end 3 structures, can prevent that puncture needle 6 from stabbing internal organs, and now the gas injection side opening 2 in air injection pipe 1 front end side wall also stretches out outside puncture needle 6, now gas injection interface 22 is just connected with pneumoperitoneum apparatus and can carries out abdominal cavity gas injection.
When carrying out laparoscopic surgery, visual area is unintelligible, seroperitoneum or other be need to suction operation time, to suction pipe 9 and insert intraperitoneal by sleeve channel, rinse and attract interface 24 first to dock with three-way valve, then be connected with Negative pressure machine with syringe pipe respectively, during flushing, flushing liquor, by 10 ejections of main suction hole 12 and side blow sucker, is attracted by main suction hole 12 and side blow sucker 10 during attraction, and the interface 22 of gas injection is simultaneously connected with pneumoperitoneum apparatus and can carries out gas injection and maintain pneumoperitoneum pressure.
According to above-described embodiment, can understand better this utility model.Yet, those skilled in the art will readily understand, the described content of embodiment is only for this utility model is described, and should also can not limit this utility model described in detail in claims.
