The stylophore of adjustable movement, the stylophore is in adjusting position, motion range range indicated by the scale of front end
It is interior.
Laparoscope in the utility model uses adjustable puncture needle by the way that scale and stylophore are arranged on needle, convenient for users to
The intubating length for controlling needle guarantees going on smoothly for operation, in addition, puncture needle is divided into removable both ends, also reduces life
Produce the manufacturing process requirement of elongated needle.
In some embodiments, the syringe needle and the backshank are attached by screw thread, and the rear end of the syringe needle is set
There is pintle, and be equipped with bolt internal screw thread on the pintle, the front end of the backshank is equipped with corresponding tail external screw thread.Thereby, it is possible to
Syringe needle and backshank are carried out detachably connected.
In some embodiments, the length of the syringe needle is 3-10cm, and outer diameter size is 16-22G.Thereby, it is possible to make
Syringe needle and backshank all have more appropriate size.
In some embodiments, the scale is arranged on the syringe needle at needle point 0.2-5cm.Thereby, it is possible to
Syringe needle is moderately inserted into affected part when in use.
In some embodiments, the backshank and the stylophore are adjustably connected by screw thread, in the needle
The outside of tail is equipped with sheath external screw thread, and is equipped with corresponding sheath internal screw thread in the inside of the stylophore.Thereby, it is possible to be arranged backshank with
Stylophore is adjustably connected.
In some embodiments, the diameter of the stylophore (3) is 0.2-0.5cm.Thereby, it is possible to the ruler of stylophore is arranged
It is very little.
Detailed description of the invention
Fig. 1 is the schematic diagram of the adjustable puncture needle of laparoscope of one embodiment of the utility model；
Fig. 2 is internal structure broken away view of the laparoscope shown in Fig. 1 with adjustable puncture needle.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 schematically shows a kind of adjustable puncture needle of laparoscope of embodiment according to the present utility model,
Fig. 2 shows the internal structure of adjustable puncture needle of the laparoscope in Fig. 1.As shown in Figs. 1-2, which includes a needle
First 1 and a backshank 2, syringe needle 1 and backshank 2 are hollow, and have the needle handle of an integrated setting in the rear end of backshank 2
4, wherein needle handle 4 is also hollow, and the size of needle handle 4 is greater than the size of backshank 2.The outside of backshank 2, which is also arranged, to be equipped with
One stylophore 3, the front end of stylophore 3 then accommodate part syringe needle 1, wherein stylophore 3 can be transported along backshank 2 in a certain range
It is dynamic, to adjust the length that syringe needle 1 is exposed to outside stylophore 3.
Syringe needle 1 and backshank 2 are the connections for can mutually dismantle by screw thread, and wherein the rear end of syringe needle 1 is equipped with pintle
12, and bolt internal screw thread 13 is equipped on pintle, corresponding tail external screw thread 21 is then equipped in the front end of backshank 2.The length of syringe needle 1 is big
About 3-10cm, outer diameter size is 16-22G, and the total length of syringe needle 1 and backshank 2 is then between 30-60cm.
Stylophore 3 is movably coupled on backshank 2 by screw thread, and wherein the outside of backshank 2 is equipped with sheath external screw thread 22,
It is then equipped with corresponding sheath internal screw thread 31 in the inside of stylophore 3, and sheath external screw thread 22 can be set up directly on backshank 2 close to needle handle 4
Place.And through reasonable settings, in the case where the width of stylophore 3 can be made relatively reasonable, sheath internal screw thread is set inside it
31.Wherein, the diameter of stylophore 3 is generally 0.2-0.5cm, and on the one hand it can effectively prevent syringe needle from further going deep into affected part, separately
On the one hand it is easy to stab card operating walk way by the laparoscope of 0.5cm again.
