Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of puncture needle, and particularly a kind of Wicresoft operation on vertebra is used puncture needle.
Background technology
In traditional surgery; Operation on vertebra needs a big edge of a knife in order to showing outstanding intervertebral disc, and for accomplishing such step, the muscle of back major part must be stripped from and being connected of vertebra; So the time that the patient recovers is longer; And surgical operation separates the pain that these muscle produced and must rely on the medicine that relieves the pain to reduce, and the patient will bear the side effects of pharmaceutical drugs that relieve the pain, and developed at present therefore that a kind of operating time is short, curative effect is fast and the patient restores Wicresoft's operation on vertebra of piece.
Carry out under the situation of Wicresoft's operation on vertebra through the inner injury of X ray demonstration patient place; In the compression vertebral body, directly inject or the implants such as bone cement, artificial bone of reinjecting through balloon expandable earlier through percutaneous; Thereby strengthen the mechanical stability of pathological changes vertebral body, the patient is restored fast.The puncture needle that present Wicresoft operation on vertebra is used is to need to insert in the sclerotin, and it is bigger that nook closing member receives resistance, has the phenomenon in the nook closing member indentation needle tubing; Therefore in the existing puncture needle be and be to be threaded in order to the fixing needle tubing seat of needle tubing in order to the fixing needle core base of nook closing member, yet though such make that nook closing member can the retraction needle tubing in, when the extraction nook closing member; Must make needle core base withdraw from the needle tubing seat needle core base rotation, in operation process, the doctor be difficult for differentiating the direction of rotation of needle core base; The situation that needle core base is tightened in existence; The doctor must could extract needle core base and nook closing member out by the counter-rotating needle core base, doctor's inconvenient operation like this, and prolonged operating time.
Summary of the invention
The purpose of this utility model is to the problems referred to above that exist in the prior art, provides a kind of simple in structure, easy to operate Wicresoft's operation on vertebra to use puncture needle.
The purpose of this utility model can realize through following technical proposal: a kind of Wicresoft operation on vertebra is used puncture needle; Comprise needle tubing that is hollow tubular and the needle tubing seat that is connected with needle tubing; And be shaft-like nook closing member and the needle core base that is connected with nook closing member; The end that described nook closing member inserts in the needle tubing and nook closing member stretches out needle tubing has cutting edge; It is characterized in that described needle core base is positioned at needle tubing seat place, and be provided with the location structure that when needle core base is posted by the needle tubing seat, can make both axial location between described needle core base and the needle tubing seat.
When this Wicresoft operation on vertebra uses in operation with puncture needle; Location structure makes needle core base and needle tubing seat axial location, during puncture nook closing member can the retraction needle tubing in, piercing process is smooth; When needs are extracted nook closing member out; The location that the nook closing member toilet that only need rotate in a circumferential direction can be removed needle core base and needle tubing seat, directly grip the nook closing member toilet and can nook closing member be extracted out this moment, convenient to operation.
Above-mentioned Wicresoft's operation on vertebra with puncture needle in, described location structure comprises the card edge that can be halved together with notch that has on the notch that radially offers on the needle tubing seat and the needle core base.When needle core base was posted by the needle tubing seat, the card of needle core base was along in the notch that embeds the needle tubing seat, and the edge of notch stops that card moves vertically, made needle core base and needle tubing seat axial location like this.
Above-mentioned Wicresoft's operation on vertebra with puncture needle in, the quantity of described notch is the obverse and reverse that two and two notches lay respectively at the needle tubing seat, the quantity on described card edge is that two and two cards are along laying respectively at the obverse and reverse of needle core base.Be arranged so that card like this along snapping in the notch easily, two card edges are stressed evenly, good operability.
Above-mentioned Wicresoft's operation on vertebra with puncture needle in, described notch is positioned at the end of needle tubing seat, described card is along the end that is positioned at needle core base.Processing is comparatively convenient like this.
Above-mentioned Wicresoft's operation on vertebra with puncture needle in, have the sign of the direction of rotation of indicating on the described needle core base.The doctor is according to sign operation, can maloperation, and easy to use.
Compared with prior art; This Wicresoft operation on vertebra makes needle core base and needle tubing seat axial location with puncture needle through location structure, and both structural stabilities are good, can guarantee that the operation puncturing process is smooth; When needs are released nook closing member; Only need the rotation needle core base to make card, just can directly extract nook closing member out along withdrawing from notch, convenient to operation.
Description of drawings
Fig. 1 is the perspective view of this Wicresoft operation on vertebra with puncture needle.
Fig. 2 is the user mode sketch map of this Wicresoft operation on vertebra with puncture needle.
Among the figure, 1, needle tubing; 2, needle tubing seat; 3, nook closing member; 4, needle core base; 5, notch; 6, card edge; 7, sign.
The specific embodiment
Below be the specific embodiment of this utility model and combine accompanying drawing, the technical scheme of this utility model is done further to describe, but this utility model is not limited to these embodiment.
This Wicresoft operation on vertebra comprises needle tubing 1 that is hollow tubular and the needle tubing seat 2 that is connected with needle tubing 1 with puncture needle; And be shaft-like nook closing member 3 and the needle core base 4 that is connected with nook closing member 3; The end that nook closing member 3 inserts in the needle tubing 1 and nook closing member 3 stretches out needle tubing 1 has cutting edge, and needle core base 4 is provided with the location structure that when needle core base 4 is posted by needle tubing seat 2, can make both axial location between needle tubing seat 2 places and needle core base 4 and needle tubing seat 2.
Specifically, like Fig. 1, shown in Figure 2, location structure comprises that the card that can be halved together with notch 5 that has on the notch that radially offers on the needle tubing seat 25 and the needle core base 4 is along 6.Notch 5 is positioned at the end of needle tubing seat 2, and the quantity of notch 5 is the obverse and reverse that two and two notches 5 lay respectively at needle tubing seat 2.Card along 6 be positioned at needle core base 4 the end, the quantity of card along 6 be two and two cards along 6 lay respectively at needle core base 4 obverse and reverse.In order to prevent doctor's maloperation, has the sign 7 of the direction of rotation of indicating on the needle core base 4.
When this Wicresoft operation on vertebra uses in operation with puncture needle; The card of initial needle core base 4 along 6 be arranged in needle tubing seat 2 notch 5, the edge of notch 5 stops that card moves axially along 6, makes needle core base 4 and needle tubing seat 2 axial location like this; During puncture nook closing member 3 can retraction needle tubing 1 in, piercing process is smooth; When needs are extracted nook closing member 3 out, the needle core base 4 that only need rotate in a circumferential direction, the notch 5 of needle tubing seat 2 is withdrawed from the card edge 6 of needle core base 4, directly grips needle core base 4 this moment and just can nook closing member 3 be extracted out, and is convenient to operation.
