Background technique
In modern medical service operation, medical use needle is widely used in the operations such as injection, puncture.In puncture process,
The puncture force size of medical use needle has a large effect to the accuracy and success rate of puncture, therefore many scholars expand pair
The research of puncture force size factor has simultaneously carried out modeling and simulating to puncture process, by puncture force detection device to puncture force size
It is detected.Current pricking device has the shortcomings that structure is complicated mostly, is only capable of vertically puncturing.Chinese utility model
The sting device that " CN201420447889.3 " is proposed can bear biggish load, however it is only suitable for detection puncture needle
Whether satisfaction produces standard, can not simulate actual puncture process.China practical new " CN201720394100.6 ", which improves, to be set
Standby security performance, but equally there is the problems such as can not simulating clinical puncture process completely.In view of the deficiencies of the prior art, originally
Utility model proposes to carry medical use needle using linear motor and pull pressure sensor is laterally moved, can XY fortune to being fixed on
The scheme that soft tissue in moving platform is punctured is realized by the transverse movement of motor to power in medical operating puncture process
Measurement.
Summary of the invention
In view of the deficienciess of the prior art, the utility model proposes a kind of cross measure of medical use pin puncture power dresses
It sets.Medical use needle is carried using linear motor and pull pressure sensor transverse movement carries out soft tissue puncture, realizes medical operating
The emulation of human body puncture process in the process.
The technical solution of the utility model is as follows:
A kind of cross measure device of medical use pin puncture power, including erecting bed 1, bottom plate 2, linear motor 3, pinboard 4,

12, medical use needle 13, soft tissue grip block 14, XY motion platform 15, support plate 16, computer control system 17, it is characterized in that
Bottom plate 2 is fixed on erecting bed 1, and linear motor 3 is installed on bottom plate 2 by bolt, and Z axis motion platform 5 is solid by pinboard 4
Due on linear motor 3, sensor mounting plate 6 is fixed on Z axis motion platform, is equipped with sensor 7 thereon and is passed through sensing
Device is installed lid 8 and is fixed, and medical use needle 13 is inserted in collet chuck 11 and is clamped on extension rod 10 by nut 12, passes through connecting rod
9 connect with sensor 7；Support plate 16 is installed on bottom plate 2 by bolt, and surface is equipped with XY axis by bolt and nut on it
Motion platform 15, soft tissue grip block 14 are installed on the top of XY motion platform 15；Computer control system 17 controls straight-line electric
The movement of machine 3 and the data of sensor 7 acquire.
The utility model has the advantages that:
(1) pass through lateral arrangement linear motor, the lateral puncture behavior of analog medical use needle.
(2) measuring device of the utility model medical use needle transverse direction puncture force, structure is simply dexterous, easy to assembly, operation
Simply.
