Description
Technical field
This utility model relates to field of medical technology, particularly a kind of manual type laser positioning lead stamp cutting machine.
Background technology
In the tumour radiotherapy process; often need to make some low melting point lead blocks and block in the irradiation field and some peripheral normal structures, so that when shining tumor tissues exactly, can protect its peripheral normal structure again with definite shape size.Existing manual lead stamp cutting machine design exists following shortcoming to have much room for improvement:
As shown in Figure 1.Because indicating arm 16 deadweight (long 30CM of existing manual lead stamp cutting machine, the rustless steel steel pole of diameter 1.5CM), indicating arm 16 bars point contacts the frictional force that produces with X-ray film 17, waste time and energy when mobile, particularly when contour line is turned, not easy to operate especially, often operator's finger is shaken, be easy to generate cutting error owing to moving effort.In addition, the operator must hands pinches indicating arm 16 lower ends makes the bar point keep in touch with X-ray film 17, in order to guarantee cutting accuracy, palm must tightly be cut X-ray film 17, then indicating arm 16 itself reaches the sight line that operator's palm just can shelter from the operator wholly or in part, can't accurately move along the target wheel profile, this brings very big inconvenience to operation.
As shown in Figure 2.Must leave an intersegmental distance between indicating arm 16 and the sleeve pipe 14, be convenient to indicating arm 16 upper and lower slip in sleeve pipe 14, like this indicating arm 16 bar points in moving process to keep tightly cutting X-ray film, indicating arm 16 needs first inclination certain angle, tangent with sleeve pipe 14 inwalls before moving, indicating arm 16, sleeve pipe 14 and the same moved further of electric heating cutting silk 15 ability, this axis that just makes indicating arm 16 and telescopic axis by overlap become crossing, article two, the intersection point of axis and X-ray film is respectively O, O ' 2 points, and spacing OO ' just can cause bigger cutting error.
Summary of the invention
The purpose of this utility model is in order to solve the deficiency that prior art exists, a kind of lead stamp error manual type laser positioning lead stamp cutting machine little, easy to operate that guarantees that manual lead stamp cutting function is accurately cut, made according to the target wheel profile to be provided.
The purpose of this utility model is to be achieved through the following technical solutions:
Manual type laser positioning lead stamp cutting machine comprises casing rack, sleeve pipe, connecting rod, electric heating cutting silk, operating board, support bar, mould bases, and it is characterized in that: described sleeve pipe bottom is connected with laser instrument.
As further improvement:
Described telescopic upper end is fixedly connected on the bottom of casing rack, the bottom of connecting rod is fixedly connected on the top of casing rack, one end of electric heating cutting silk is connected the connecting rod lower surface, the other end is connected the sleeve pipe upper surface, support bar is fixed on the supporting seat, mould bases is fixedly connected on the support bar middle part, and the connecting rod top movable is hinged on the support bar.
Described connecting rod is connected on the support bar by universal active section.
The external diameter of described laser instrument and telescopic internal diameter match, and laser instrument is set in the sleeve pipe.
Described laser instrument and sleeve pipe are by being threaded.
Has spacing between described laser instrument and the operating board.
Described laser instrument has the focusing lens group.
Be provided with adjustable background light source in the described operating board.
The utlity model has following advantage:
1, changing existing contact-type indicating arm is and the laser instrument of operating board non-contact type to have eliminated the frictional force between indicating device and the X-ray film; Simultaneously, this improvement can alleviate the weight of indicating device to a great extent, and then makes operation very light.
2, laser instrument is fixed in the sleeve pipe, has eliminated the error of bringing by the gap between laser instrument and the sleeve pipe in the moving process basically.
3, owing to adopt the non-contact type laser positioning, has certain spacing (about 5CM, the technician can suitably adjust according to the operating habit of oneself) at laser instrument and operating board sheet; Simultaneously, because the weight saving of indicating device own, but the operator need only tightly pinch laser instrument, middle finger with thumb and forefinger and tightly cut X-ray film with just flexible operating of the balance that keeps operation posture, the operator see through laser instrument, middle finger, and X-ray film between the space just can be observed the position of target wheel profile, solved the problem that operator's sight line is blocked.
Description of drawings

Fig. 2 is the user mode partial enlarged drawing of existing manual type lead stamp cutting machine.
Fig. 3 is the structural representation of this utility model manual type laser positioning lead stamp cutting machine.
The specific embodiment
Embodiment 1: as shown in Figure 3.The supporting mechanism of this machine comprises the supporting seat 1 of bottom, the support bar 2 on top, and support bar 2 is fixedly connected on the supporting seat 1, and operating board 3 is fixed on the supporting seat 1, mould bases 4 is fixed on support bar 2 middle parts, is provided with adjustable background light source in the operating board 3.The top of connecting rod 5 hangs on support bar 2 upper and lower parts by universal active section 11 and fixedlys connected with the top of casing rack 6; Fixedly connected with the bottom of casing rack 6 in the upper end of sleeve pipe 7, the bottom is fixedly connected with laser instrument 8, laser instrument 8 fixed covers be loaded in the sleeve pipe 7 or by screw thread fixedly connected with sleeve pipe 7, head exposes outside sleeve pipe 7, has spacing between laser instrument 8 heads and operating board 3 surfaces; Be fixedly connected with electric heating cutting silk 9 between the upper surface of the lower surface of connecting rod 5 and sleeve pipe 7.Described operating board is used to place the X-ray film 12 that is decorated with contour line; Above-mentioned mould bases 4 stretches in the space that casing rack 6 surrounded, the foam plastics 13 of making lead stamp to be cut that is used to place.Above-mentioned electric heating cutting silk 9 drives same moved further with laser instrument 8 by casing rack 6.
The using method of this machine is: with X-ray film 12 be fixed on operating board 3 middle parts, the foam plastics 13 that is slit into mould to be cut is fixed on the mould bases 4, the laser beam that utilizes laser instrument 8 to be sent can form a little indication point that has color on X-ray film 12, indicate cutting position with little indication point; The operator need only tightly pinch laser instrument 8, middle finger with thumb and forefinger and tightly cut X-ray film 12; The little indication point that laser instrument 8 sends moves along the contour line of X-ray film 12 and makes cutting track, cut out the mould of making plumbous link stopper with laser instrument 8 synchronization-moving electric heating cutting silks 9 according to cutting track in foam plastics to be cut 13, the liquid lead of pouring fusing in this lead stamp just can be made required lead block.Little indication point for outstanding laser instrument 8 is sent should dim the background light sources in the operating board 3, so that as seen little indication is checked up clear.
For reducing electric heating cutting 9 lead stamp of making and the error between the contour line on the X-ray film 12, the more little location of the spot diameter of the small red dot that laser instrument 8 sends lead stamp precision just more accurate, that make is high more.For reaching above-mentioned effect, the head of laser instrument 8 has focusing lens group 10, focuses by the laser beam that 10 pairs of laser instrument 8 of focusing lens group send, and makes the little finger of toe that drops on the X-ray film 12 show that spot diameter is littler.
