The utility model has the advantages of scientific and reasonable structure, convenient use, convenient operation and safety. The utility model is convenient to popularize and apply on clinic.
Description
This utility model relates to a kind of peritoneoscope safety puncture needle, belongs to medical instruments field.
At present, the syringe needle of the peritoneoscope puncture needle of Ying Yonging all is in exposed state clinically, accidentally injures normal structure when implementation and operation easily, and makes operation technique existence inconvenience to a certain degree.
The purpose of this utility model is to provide a kind of peritoneoscope safety puncture needle, uses easy to operate, safe and reliable.
Peritoneoscope safety puncture needle described in the utility model, its syringe needle is arranged in a sleeve pipe, and sleeve pipe is fixed in the front end of handle, and the rear end of syringe needle is connected on the removable core bar in the intracavity of handle, and core bar is provided with return spring and fixing and locking device.
Syringe needle of the present utility model can be hidden in the sleeve pipe, adjusts the exposure or the hiding situation of syringe needle as required, and is safe and reliable, avoided accidentally injuring the phenomenon of normal structure, and makes that use is more convenient to operate.
For simplified structure, handled easily, in this utility model:
Return spring is designed to compressing spring, is located between the preceding capping of core bar and handle.
Fixing and locking device is designed to be made of corresponding groove on shadoof on the handle and the core bar.
In order to limit the mobile degree of core bar, can on handle, be provided with and limit the spacing handle rear end lid that core bar moves.
Below in conjunction with the embodiment accompanying drawing this utility model is further described.
The structural representation of Fig. 1, this utility model one embodiment.
Among the figure: 1 syringe needle, 2 connection tubes, 3 sleeve pipes, 4 handle drive end bearing brackets, 5 compressing springs, 6 core bars, 7 handles, 8 springs, 9 are carried button, 10 shadoofs, 11 are carried button seat, 12 handle rear ends lid, 13 grooves.
As shown in the figure, peritoneoscope safety puncture needle described in the utility model, its syringe needle 1 is arranged in sleeve pipe 3, and sleeve pipe 3 is fixed in the front end of handle 7, the rear end of syringe needle 1 is connected on the removable core bar 6 in handle 7 inner chambers by connection tube 2, and core bar 6 is provided with reset compressing spring 5 and fixing and locking device.Compressing spring 5 is located between the preceding capping 4 of core bar 6 and handle, and fixing and locking device is made of corresponding groove 13 on shadoof on the handle 6 10 and the core bar 6.
During use, mention shadoof 10, core bar 6 moves to the rear end of handle 7 under the effect of compressing spring 5, and syringe needle 1 moves thereupon, is retracted in the sleeve pipe 3 to stash.At this moment, puncture needle can be sent in the abdominal cavity, be treated puncture needle in the operating field fluorescent screen, when needing to implement puncture, promote core bar 6, make syringe needle 1 lean out sleeve pipe 3, be in exposed state,, behind the position and lock, implement puncture procedure by shadoof 10 and groove 13.Behind the EO, on shadoof 10, syringe needle 1 automatically retracts to again in the sleeve pipe 3 and stashes, and is convenient to take out from the abdominal cavity.
In actual applications, syringe needle, connection tube and core bar are interconnected, and the rear end of core bar is an injection seat, can connect syringe, so that when implementing puncture, carry out associative operations such as drawing liquid, injection, biopsy.
This utility model is scientific and reasonable for structure, and use, easy to operate, safe and reliable is convenient to apply clinically.
