Abstract
The utility model discloses an adjustable length guide needle, including syringe needle and handle, the handle is the hollow tube, and the syringe needle can be in the handle the telescopic adjustment length, and the handle front end is equipped with the locking device that can fix the syringe needle, and this technical scheme has replaced the guide needle of a plurality of different length and model in the past with the guide needle of an adjustable length, has removed the operation of changing different length guide needles from the operation in-process from for operate more convenient and fast.
Description
Technical Field
The utility model belongs to the field of medical equipment, a adjustable length guide needle is related to.
Background
At present, in the cosmetic surgery, especially in the thread carving operation, the purpose of suspension and lifting is achieved by implanting medical absorbable polymer chemical synthetic thread under the skin, lifting muscles, tightening the skin and stimulating the regeneration of collagen.
The needle body and the handle of the guide needle that are used at present are fixed connection structures, for example, utility model patent CN2877575Y discloses a facial lift-up operation guide needle, including syringe needle and handle, syringe needle and handle fixed connection are in the same place, hold the depth of puncture through the scale on the needle body, however, this kind of guide needle has corresponding problem when using, for example, when doing the short distance puncture, needle body length is longer relatively, leads to holding the position far away from the syringe needle, and the controllability is not good.
Although the prior art has been designed to accommodate different puncture distances by manufacturing guide needles with different lengths without affecting the maneuverability, the guide needles with different lengths must be replaced when puncturing with different distances, thereby causing inconvenience in operation and affecting the efficiency of the operation.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can conveniently adjust guide needle of syringe needle length.
The utility model has the following concrete scheme: the adjustable-length guide needle comprises a needle head and a handle, wherein the handle is a hollow tube, the needle head is arranged in the handle, the length of the handle is 10cm-15cm, the inner diameter of the handle is 2mm-3mm, the outer diameter of the handle is 9mm-11mm, the diameter of the needle head is 1.2mm-1.6mm, a needle hole used for penetrating a lead is formed in the tip end of the needle head, a locking device capable of fixing the needle head is arranged at the front end of the handle, and the needle head can stretch out and draw back in the handle and can be fixed at a plurality of locking positions to adjust the extending length of the needle head.
According to the utility model discloses an adjustable length guide needle, locking device includes the jackscrew, the handle lateral wall is equipped with the screw hole, the jackscrew with the screw hole cooperation is through to the inside rotation of handle the jackscrew makes the axial displacement of syringe needle is restricted, thereby right the syringe needle is fixed a position.
According to the utility model discloses an adjustable length guide pin, the portion of screwing up of jackscrew is processed there is anti-skidding texture.
According to the length-adjustable guide needle of the utility model, the length-adjustable interval of the needle head is 5cm-20 cm.
According to the utility model discloses an adjustable length guide needle, the handle is made by stainless steel.
The utility model has the advantages that:
the utility model relates to an adjustable length guide needle can adjust syringe needle length according to operation needs convenient and fast ground, has not only guaranteed the doctor to the nature controlled of guide needle when doing different distances puncture, can also reduce surgical instruments, avoids the operation frequently to change different specification guide needles on the way, has improved operation efficiency. In addition, the utility model relates to a syringe needle of different models can also be changed as required to the guide needle, for example triangle-shaped syringe needle or flat syringe needle, and the syringe needle of the supporting multiple model of same handle has further simplified surgical instruments.
