Description

The pneumoperitoneum pin

Technical field

This utility model relates to a kind of pneumoperitoneum pin, is mainly used in Wicresoft's peritoneoscope medical operating, to the treatment that undergos surgery of disease in the human body body.

Background technology:

In the human body body, in Wicresoft's peritoneoscope medical operating,, need operation or excision in case in the human body body, find focus, in operation process, need be to carrying out pneumoperitoneum in the human body, make having in the human body certain space, the operation virtue can carry out.Prior art generally is to cut human abdominal cavity to carry out medical operating, and its defective is: need to cut human abdominal cavity, operating theater instruments is inserted human abdominal cavity from otch, brings great trouble to the healthcare givers; Also exempt from pneumoperitoneum Wicresoft peritoneoscope medical operating, but generally be minor operation, the joint tissue of treatment human body is difficult to intraperitoneal is undergone surgery, and satisfies unexpectedly ideal surgical effect.

The utility model content:

Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of reasonable in design is provided, human oriented design, operation safe, effective pneumoperitoneum pin easy to use.

The technical scheme in the invention for solving the above technical problem is: this pneumoperitoneum pin, it is characterized in that: be provided with needle tubing, needle tube joint, the gas bar, nut, spring, spring base, valve, key seat, inner core is taken over, syringe needle, needle tubing is fixedlyed connected with syringe needle, needle tubing is fixedlyed connected with needle tube joint, have the gas outlet on the gas bar, the gas bar is taken over inner core and is fixedlyed connected, have cotter way in the spring base, inner core is taken over and is fixedlyed connected with key seat, nut and inner core adapter are tightened fixing, and spring is inserted in inner core to be taken over, and spring base is inserted in inner core to be taken over, key seat cooperates with cotter way, and valve and inner core adapter are tightened fixing.

Needle tubing described in the utility model and syringe needle are connected as a single entity.

This utility model compared with prior art has the following advantages and effect: reasonable in design, and human oriented design, the safe effect easy to use of performing the operation is good.

Description of drawings:

Fig. 1 is the structural representation of this utility model embodiment.

Fig. 2 is the connection diagram of this utility model embodiment needle tubing and syringe needle.

Fig. 3 is the sketch map of this utility model embodiment agent structure.

Fig. 4 is the connection diagram that this utility model embodiment key seat and inner core are taken over.

The specific embodiment:

Referring to Fig. 1～Fig. 4, this utility model embodiment pneumoperitoneum pin is provided with needle tubing 1, needle tube joint 2, gas bar 3, nut 4, spring 5, spring base 6, valve 7, gas outlet 8, cotter way 9, key seat 10, inner core adapter 11, syringe needle 12, have gas outlet 8 on the gas bar 3, gas bar 3 is taken over 11 welding with inner core and is fixed; Have cotter way 9 in the spring base 6; Inner core adapter 11 is fixing with key seat 10 welding, and nut 4 and inner core adapter 11 are tightened fixing, and spring 5 is inserted in inner core takes over 11, and spring base 6 is inserted in inner core takes over 11, and key seat 10 snaps in cotter way 9 just can be up and down; Valve 7 is tightened fixing with inner core adapter 11.

Present embodiment needle tubing 1 and syringe needle 12 are one, and needle tubing 1 and needle tube joint 2 welding are fixing.

The present embodiment agent structure is inserted in needle tubing 1 and needle tube joint 2, and needle tube joint 2 and spring base 6 are tightened fixing, promptly form complete present embodiment (Fig. 1).

The pneumoperitoneum pin of this utility model design in Wicresoft's laparoscopic surgery, inserts the pneumoperitoneum pin in the human body body.As long as qi of chong channel ascending adversely equipment is installed on valve, air-flow enters human body in the pneumoperitoneum pin, form the space in human abdominal cavity, healthcare givers's treatment that undergos surgery in the space.

The pneumoperitoneum pin of this utility model design, because the design of spring 5, can slide between internals (needle tubing 1 and needle tube joint 2) and the outer part (agent structure), in operation is used, when the pneumoperitoneum pin penetrates human body, press internals, the gas bar is outstanding forward, the pneumoperitoneum pin can carry out activity in human body, syringe needle can not damage its hetero-organization in the human body; Decontrol internals, under the effect of spring, the pneumoperitoneum pin resets, and the innovation of technology belongs to domestic initiation at present.

The pneumoperitoneum pin of this utility model design, easy installation and removal, metal material is made, can cleaning and sterilizing, also can high-temperature sterilization.

The simple deformation or the combination of every this utility model embodiment technical scheme and technical characterictic all should be thought to fall into protection domain of the present utility model.
