Description
technical field:
This utility model is relevant with bone marrow aspiration holder, and especially to determine angle marrow puncture fixator relevant with depthkeeping.
background technology:
In clinical practice, bone marrow aspiration is one of basic Clinical operational skill, and operator is had relatively high expectations.Existing bone marrow puncture device (being called for short " bone is worn ") is one " needle-like " sharp weapon, can meet conventional ilium sour jujube puncture, if but be used in presternum puncture upper (some crowd as: old age, special disease etc. need carry out breastbone position bone and wear inspection), because lacking, " bone is worn " pin determines angle and fixture, very easily because needle angle is improper, the uncertain factor such as double swerve is damaged the vitals such as the contiguous heart of sqternal puncture point, lung, trunk and occurred accident in inserting needle process, the utmost point needs to improve.
utility model content:
The purpose of this utility model is in order to provide one to determine angle by depthkeeping, avoids operation to move, rock, the depthkeeping degree bone marrow aspiration holder of damage organ.
The purpose of this utility model is achieved like this:
This utility model depthkeeping is determined angle bone marrow aspiration holder, the first support, the second support connects into entirety by rack connecting plate, first, between the second support, there is vertical free bearing through hole, the first support, on the second support opposite position, there is coaxial and axis first axis hole vertical with vertical free bearing through-bore axis respectively, the second axis hole, cylindrical free bearing is arranged in vertical free bearing through hole and axis is vertical with vertical free bearing through-bore axis, on the corresponding surface of free bearing, have respectively and the first axis hole, the first axle of the second axis hole sliding fit, the second axle, the second shaft extension goes out the first locking nut that has threaded engagement on the end of the second axis hole, on free bearing, there is the guiding centre tapped through hole vertical with axis, the end face that free bearing is positioned at guiding centre tapped through hole is plane, the bottom shape of the guiding cored screw coordinating with guiding centre tapped through hole is spherical and top is counter sink, on guiding cored screw, there is the second locking nut coordinating with guiding cored screw the position of free bearing top planes relatively, the scale that has the expression degree of depth on the position of the observation port that communicates with counter sink and relative observation port is arranged at guiding cored screw top, the scale that represents angle is arranged at the top of the first support and/or the second support, the first support, on the second frame bottom opposite position, there is respectively bandage fixed ear base, the two ends of bandage are contained in respectively on the fixed ear base on first, second support.
Above-mentioned rack connecting plate adopts transparent lucite to make, so that doctor observes the bulb contact patient's of guiding cored screw end inserting needle position while operating.
When work, puncture needle fixer is fixedly tied to patient chest with bandage.Swing free bearing, make the guiding cored screw being threaded with it in best effort angle, (the maximal regulated scope of this angle be ± 45 °) turn first locking nut is to determine the accurate orientation of puncture needle, rotary steering cored screw, the bulb of its bottom is touched behind patient's inserting needle position, turn the second locking nut to be to determine the depthkeeping of puncture needle, puncture needle inserted to the puncture needle that just can start to locate depthkeeping in the hole of guiding cored screw and operated.
This utility model is fixed on existing medullo-puncture needle to treat inserting needle site of puncture, displacement while avoiding operating, rocks etc.; Coordinate with existing medullo-puncture needle, can set up the medullo-puncture needle degree of depth, avoid deeply damaging adjacent organs because puncturing; Can set up the bone degree of medullo-puncture needle, avoid puncture angle to change and the vitals such as heart, lung, trunk that damage sqternal puncture point is close to, safety.

detailed description of the invention:
Referring to Fig. 1～Fig. 4, the present embodiment 1 depthkeeping is determined angle bone marrow aspiration holder, and the first support 1, the second support 2 connect into entirety by rack connecting plate 3.Between first, second support, there is vertical free bearing through hole 4.On the first support, the second support opposite position, there is coaxial and axis first axis hole 5, second axis hole 6 vertical with vertical free bearing through-bore axis respectively.Cylindrical free bearing 7 is arranged in vertical free bearing through hole and axis is vertical with vertical free bearing through-bore axis.On the corresponding surface of free bearing, there are respectively the first axle 8, the second axle 9 with the first axis hole, the second axis hole sliding fit.The second shaft extension goes out the first locking nut 10 that has threaded engagement on the end of the second axis hole.On free bearing, there is the guiding centre tapped through hole 11 vertical with axis.The end face 12 that free bearing is positioned at guiding centre tapped through hole is plane.It is counter sink 14 that the bottom 13 of the guiding cored screw coordinating with guiding centre tapped through hole is shaped as spherical top.On guiding cored screw, there is the second locking nut 15 coordinating with guiding cored screw the position of free bearing top planes relatively.The scale 17 that has the expression degree of depth on the position of the observation port 16 that communicates with counter sink and relative observation port is arranged at guiding cored screw top.The top opposite position of the first support and the second support has respectively the scale 18 that represents angle.On first, second frame bottom opposite position, have respectively bandage fixed ear base 19, the two ends of bandage 20 are contained in respectively on bandage fixed ear base.Rack connecting plate adopts transparent lucite to make.
Fig. 5 is this utility model work schematic diagram.
