Abstract
The utility model discloses a medical deformable guide needle, which belongs to a surgical operation instrument. The medical deformable guide needle comprises a cylindrical needle body and a needle point part with a threading hole formed at one end, wherein the needle body is a stainless steel wire with certain flexibility, a thread passing notch is formed on one side of the longitudinal axis of the elliptical threading hole of the flat needle point part, and one end of the needle body is bent to form a long annular handle. As the needle body has certain flexibility, the medical deformable guide needle with the design can change the shape with a head form under the aponeurosis conveniently; the thread passing notch is formed on one side of the major axis of the elliptical threading hole of the flat needle point part, so as to facilitate thread passing and prevent the thread from running and falling; and the long annular handle facilitates holding by an surgeon. Therefore, the medical deformable guide needle becomes a dedicated surgical instrument for an upper facial part lift.
Description
Technical field
This utility model relates to surgical operating instrument, specifically is a kind of medical distortion guide needle.
Background technology
The medical guide pin is the medical apparatus and instruments that clinical medicine uses, and shape, the structure of guide needle are different, as are provided with the bone marrow aspiration guide needle of guiding sleeve, guiding puncture urethral catheterization trocar, cerebrospinal fluid puncturing guide needle etc.; The guide needle that directly is used for guide slit zygonema or guide line is the direct rod shape needle body, and an end is formed with the circular pin hole that connects stitching thread or guide line.
Chinese patent 2065882 discloses a kind of " tendon guide needle ", and it is that cone, afterbody central longitudinal are formed to the needle body of attacking threaded circular hole, backshank and pressurization axle sleeve by head.One end of backshank is a bolt shaft, and is having pinprick near one of truncated cone, and the other end is a truncated cone, and one side vertically has a groove along the pinprick hole; The pressurization axle sleeve is a cylinder, and two ends are attacked threaded circular hole and conical butt hole along central longitudinal to having; The bolt shaft of backshank was connected with the needle body tailing screw flight after pressurization axle sleeve conical butt hole one end revolves circular hole again.It can be opened subcutaneous and tendon guiding completion synchronously.
But, at Minimally Invasive Surgery particularly in the dental sursery operation, as above face lift art; Need to come and go guiding high-tension polyester line down to temples at fornicate scalp galea aponeurotica; And overhead hit exactly derivation in the long otch of 1cm, and circular hole staight needle rigidity is strong, can not under aponeurosis (aponeuroses), guide with the head profile to walk; Pin hole inconvenience threading is difficult to satisfy the Minimally Invasive Surgery requirement.
Summary of the invention
This utility model be exactly for solve guide needle crooked be convenient to the problem of threading, and a kind of medical distortion guide needle is provided.
This utility model is realized according to following technical scheme.
A kind of medical distortion guide needle; Comprise that a cylindrical needle body and an end thereof form the needle tip of through wires hole; And needle body is to have certain flexible STAINLESS STEEL WIRE, and the longitudinal axis one side of the oval through wires hole in flat body acupuncture tip was formed with the line gap, needle body other end flexagon growth annular hand grip.
This utility model of design because needle body has certain pliability, is convenient under aponeurosis (aponeuroses), change shape with head dummy like this; The line gap of crossing that the longitudinal axis one side of the oval through wires hole in flat body acupuncture tip forms was beneficial to line, and prevented that cabling from coming off, and long annular hand grip is convenient to the patient and is gripped, and became top surface portion and promoted the special-purpose operating theater instruments of art.
Description of drawings
Fig. 1 is this utility model perspective view;
Fig. 2 is the structure for amplifying sketch map of A portion among Fig. 1.
Among the figure: 1. needle body 2. through wires holes
3. needle tip 4. is crossed the line gap
5. handle.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment this utility model is carried out detailed explanation.
A kind of medical distortion guide needle; Comprise that cylindrical needle body 1 and one of which end form the needle tip 3 of through wires hole 2; And needle body 1 is to have certain flexible STAINLESS STEEL WIRE; The longitudinal axis one side of flat body acupuncture tip 3 oval through wires holes 2 was formed with line gap 4, needle body 1 other end flexagon growth annular hand grip 5.
Described medical distortion guide needle, it has certain flexible STAINLESS STEEL WIRE is the 316L STAINLESS STEEL WIRE.
Described medical distortion guide needle, the longitudinal axis of its flexagon growth ring handle 5 and the dead in line of needle body 1.The longitudinal axis of oval through wires hole 2 is consistent with the axis of needle body 1.
Described medical distortion guide needle, the rigidity of the front portion of its needle tip 3 and handle 5 is greater than the rigidity of needle body 1.
During making, only preceding 2cm and the handle 5 at needle tip 3 quenches.Thereby making that needle body 1 is stressed slightly can be crooked with head dummy.
This utility model sample total length 160mm, needle body 1 diameter 2.5mm, handle 5 long 95mm, the longitudinal axis of oval through wires hole 2 is axially consistent with needle body 1, the longitudinal axis 3mm of through wires hole 2, transverse axis 1mm.And oval through wires hole 2 can prevent to come and go cabling the time draught line deviate from from crossing line gap 4.
When this utility model used, crown median incision inserted the guide needle of band wire, and the rear portion of needle body 1 and needle tip 3 is crooked with head dummy, inserted behind temples, extracts guide needle, and lead (not shown) opisthotonos is returned, and underwent operative promotes buccal.
