Background technology
During puncture, the many pins that puncture may be needed, and puncture a complete pin and location terminate after, puncture again second time first pin operator cannot go again to fix, the normal puncture of second pin will be affected, can perturbation operation person, the pin of puncture before also likely encountering, cause it to move, have to again locate, increase operating time and patient suffering.Sometimes, only need puncture pin, but also need when determining the position of pin to reorientate according to image, and at this moment, pin relies on human body to be fixed, and may have deviation.
Utility model content
The purpose of this utility model is to provide a kind of puncture positioning device, the fixing puncture needle terminated that punctured, and can prevent from affecting subsequent operation.
The technical solution of the utility model is:
Puncture positioning device, comprise base plate and crossbeam that cross section is arc, crossbeam is horizontally installed on the top of base plate, and the arc of base plate raises up, and base plate is evenly provided with several vertical through holes, and edge, the base plate left and right sides is equipped with bottom slide track; The two ends, left and right of crossbeam are all connected with vertical rod, and vertical rod is vertically arranged, and the lower end of vertical rod is connected with base slider, and the bottom slide of base slider side corresponding to base plate connects, and the outside of base slider is provided with sliding block locking mechanism; Laterally offer crossbeam slideway in described crossbeam, slidably connect crossbeam slide block in crossbeam slideway, pass crossbeam from top to bottom at the cross section entablature slideway of crossbeam, crossbeam slideway passes crossbeam from left side or right side, and the side of corresponding crossbeam slide block is provided with projection; The top of crossbeam slide block is connected with sleeve lock catch; Vertically vertical core of threading a needle is provided with in described crossbeam slide block.
The lower end of crossbeam slide block is provided with external screw thread, and the lower end of crossbeam slide block has been threaded setscrew nut.
Limit, the described base plate left and right sides is provided with scale.
Described crossbeam is provided with scale.
Sliding block locking mechanism comprises and is laterally located at internal thread hole in base slider and locking nut.
Locking nut is wing nut.
Sleeve lock catch comprises multiple circumferentially spaced convex tongue, and convex tongue end is provided with boss, and the periphery of boss forms outer inclined-plane; Meanwhile, the oral area of exterior lock tube is provided with groove, and the circumferential inner wall of groove forms interior inclined-plane, and boss and recess, when exterior lock tube drives convex tongue inwardly to gather, convex tongue compresses the puncture needle be positioned in the middle of convex tongue.
This utility model can utilize crossbeam and crossbeam slide block to be fixed location to puncture needle, prevents the variation of the position of puncture needle, reduces maloperation and hinders follow-up operation of threading a needle, very convenient.The base plate of arc can be placed on the thoracic cavity of human body, and the base slider that can lock and crossbeam slide block can positioning and locking puncture needles rapidly, prevent it from moving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
As shown in Figure 1, 2, puncture positioning device of the present utility model, comprise base plate 1 and crossbeam 2 that cross section is arc, crossbeam 2 is horizontally installed on the top of base plate 1, and the arc of base plate 1 raises up, and arcuate shape should be suitable with the shape of human chest.Base plate 1 is evenly provided with several vertical through holes 3, the distribution density of through hole 3 should to facilitate puncture for principle.Edge, base plate 1 left and right sides is equipped with bottom slide track 4; The two ends, left and right of crossbeam 2 are all connected with vertical rod 6, and vertical rod 6 is vertically arranged, and the lower end of vertical rod 6 is connected with base slider 7, and the bottom chute 4 of base slider 7 side corresponding to base plate is slidably connected, and the outside of base slider 7 is provided with sliding block locking mechanism; Sliding block locking mechanism comprises and is laterally located at internal thread hole in base slider and locking nut 8, and locking nut 8 is wing nut.
Laterally crossbeam slideway 5 is offered in crossbeam 2, crossbeam slide block 9 is slidably connected in crossbeam slideway 5, crossbeam 2 is passed from top to bottom at the cross section entablature slideway 5 of crossbeam, crossbeam slideway 5 passes crossbeam 2 from left side or right side, the side of corresponding crossbeam slide block 9 is provided with projection 9-1, and projection 9-1 can make crossbeam slide block 9 not move up and down; The top of crossbeam slide block 9 is connected with sleeve lock catch 10, sleeve lock catch 10 is prior art, identical with the buckle structure between metal mop phase connecting rod, comprises multiple circumferentially spaced convex tongue 13, convex tongue 13 end is provided with boss, and the periphery of boss forms outer inclined-plane; Meanwhile, the oral area of exterior lock tube 14 is provided with groove, and the circumferential inner wall of groove forms interior inclined-plane, and boss and recess.Rotating exterior lock tube 14 can make convex tongue 13 inwardly gather, and compresses the puncture needle 12 be positioned in the middle of convex tongue 13.
When sleeve lock catch 10 is locked, the end face that exterior lock tube 14 is pressed in crossbeam 2 coordinates projection 9-1 just crossbeam slide block 9 can be locked.
Vertical core 11 of threading a needle vertically is provided with in crossbeam slide block 9.Diameter and puncture needle 12 diameter to be worn of vertical core 11 of threading a needle is suitable.
The lower end of crossbeam slide block 9 is provided with external screw thread 15, and the lower end of crossbeam slide block 9 has been threaded setscrew nut 16, coordinates projection 9-1, makes crossbeam slide block 9 be fixed on some positions.
Base plate 1 and limit, crossbeam 2 left and right sides are equipped with scale, facilitate people's moving beam 2 and crossbeam slide block 9 as required.
Use procedure: manually promote crossbeam 2 and move forward and backward suitable position, then use locking nut 8 by crossbeam 2 stationary positioned.Then promote certain puncturing hole place of crossbeam slide block 9 to transverse direction, then fix with sleeve lock catch 10 and setscrew nut 16.Then puncture needle 12 is entered human body through the through hole 3 of threading a needle on vertical core 11 and base plate 1, puncture completes.Puncture after a pin, then by identical step, an other crossbeam has been positioned and punctures fixing.
