Abstract
The utility model relates to the field of medical instruments, and especially relates to a tool which is matched with a radio frequency puncture needle for use. An auxiliary tool for operating the radio frequency puncture needle comprises a pedestal and a connecting rod, the connecting rod is provided with a movable joint and a steering mechanism, one end of the connecting rod is provided with a carriage, the other end of the connecting rod is connected with the pedestal, and the pedestal is provided with an arrestment mechanism. According to the utility model, a doctor can rapidly and accurately locate an inserting needle, damages and correlative complications brought to patients by repeated puncture are reduced, radiation damages to doctors and patients caused by CT equipment are reduced, and the loss of the CT equipment is reduced.
Description
Technical field
This utility model relates to medical instruments field, more particularly, relates to a kind of and matching used instrument of radio frequency puncture needle.
Background technology
Radio frequency puncture needle is mainly used in the treatment of various tumors and lumbar intervertebral disc.Because radio frequency puncture needle and some adnexaes adopt metal material manufacture mostly, weight is heavier, especially the adnexa such as the radio frequency sleeve pipe of radio frequency puncture needle rear end and needle cannula, make to move after radio frequency puncture needle center of gravity and be difficult to hold, and its gravity is pulled by wire also can affect and changes unpredictably.Doctor, when operation radio frequency puncture needle, should get hold of the gravitational equilibrium of radio frequency puncture needle, holds again the factors such as needle angle and the degree of depth.If doctor is when carrying out pulmonary masses puncture and need repeatedly CT scan location, needs mobile CT scan platform, and constantly adjust direction, angle and the degree of depth of puncture needle, finally to determine that puncture needle is positioned at lump.The inventor finds in real work: diseased region, size of tumor difference affect very large on puncture location, focus is little, be positioned at cardiovascular injuries around or because of rib, the scapula person of the stopping positioning difficulty that punctures large, need repeatedly CT scan location, thought is not when high concentration person and lack of skill person operate radio frequency puncture needle, easily produce pin displacement, locate the problems such as inaccurate, when serious, also can cause hemopneumothorax equivalent damage to patient.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of aid that operates radio frequency puncture needle, when it can help doctor to operate radio frequency puncture needle, holds the balance of needle set, and grasps angle and the degree of depth of inserting needle.
The purpose of this utility model is achieved in that a kind of aid that operates radio frequency puncture needle, it consists of base and connecting rod, and connecting rod has movable joint and steering mechanism, and one end of connecting rod is provided with bracket, the other end of connecting rod connects base, and base has arrestment mechanism.
Advantage of the present utility model is as follows:
Because connecting rod has movable joint and steering mechanism, one end of connecting rod is provided with bracket, and the other end of connecting rod connects base, and base has arrestment mechanism and can firm banking; Bracket is used for supporting doctor's wrist or needle set, and the movable joint on connecting rod and steering mechanism are direction and the positions for movement, maintenance bracket.So, the appropriate location before base is placed on CT platform, when doctor carries out radio frequency needle puncture procedure, doctor's wrist or needle set on hand can rely on bracket, thereby realize the calm inserting needle that has support.Effect of the present utility model is equivalent to " the having the shooting of support " in military technology, even if new hand also easily hits the mark.This utility model contributes to eliminate in the rear CT scan observation process of the preliminary puncture of radio frequency puncture needle because action of gravity causes radio frequency puncture needle stern settlement, increased the stability of radio frequency puncture needle in CT scan process, make doctor can fast, accurately locate inserting needle, reduce CT location scanning number of times, shortened radio frequency piercing process, damage and related complication that thereby can greatly reduce repeatedly punctures brings to patient, increased the curative effect of radio-frequency (RF) ablation, also alleviate the radiation damage that CT equipment causes doctor and patient simultaneously, reduced the loss to CT equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model band clamping device;
Fig. 2 is the structural representation on this utility model Tape movement chassis.
The specific embodiment
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail:
Referring to Fig. 1 and Fig. 2.Operate an aid for radio frequency puncture needle, it consists of base and connecting rod.In order to make base 9 be fixed on appropriate location, on base 9, be provided with arrestment mechanism.Arrestment mechanism on base 9 can be clamping device as shown in Figure 1, or roller as shown in Figure 2 202.Roller 202 strap brakes, described base is provided with roller 202, and roller 202 has brake gear.Certainly, the arrestment mechanism on base 9 can also be the sucker of negative pressure of vacuum structure etc.
Referring to Fig. 1.2,2 movable joints 2 of movable joint that consist of 2 universal ball ends connect together 4 connecting rods 3 and form steering mechanism; In movable joint 2, be provided with mechanism and the hook knob 1 in locking joint.Also be noted that and can use the locking mechanism on Magnetic gauge stand, this locking mechanism has a plurality of movable joint, but only need use a hook knob 1.In addition, the moving less locking spanner 6 of rotational angle can also be set on that vertical root connecting rod 3, locking spanner 6 is equally for locking movable joint 2.
One end of connecting rod 3 is provided with bracket 4, can be according to doctor's operating habit, the radio frequency that supports the hand rest of doctor's wrist or the play the guiding role support 5 of threading a needle is installed on bracket 4.When the radio frequency play the guiding role being installed on bracket 4 threading a needle support 5, described bracket has the radio frequency support 5 of threading a needle.The other end of connecting rod 3 connects base 9, and the arrestment mechanism of base 9 is used clamping device, and described base is provided with clamping device.Clamping device consists of the crotch 10 on base 9, pressing plate 11 and lock screw 8.One end that connecting rod 3 connects base 9 also can arrange nut lock compact form elevating mechanism 7, between described base and connecting rod, has elevating mechanism.Measuring rod on the structure of nut lock compact form elevating mechanism 7 and the similar platform scale of principle.
Fig. 2 is another kind of embodiment of the present utility model.The bracket that connecting rod 3 one end arrange consists of wrist support 200 and the radio frequency support 5 of threading a needle.Doctor can select wrist support 200 and the radio frequency support 5 of threading a needle to have support inserting needle according to field condition and use habit in when operation.The other end of connecting rod 3 connects base 9, and the arrestment mechanism of base 9 is used the roller 202 that brake is housed, and when doctor moves to the appropriate location of CT platform by base 9, can chassis 9 be positioned to desired location by the brake on roller 202.One end that connecting rod 3 connects base 9 also can arrange Manual elevator mechanism 201, the elevating mechanism on the structure of Manual elevator mechanism 201 and principle similar industrial milling machine.
