Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 4, the present invention provides a bladder stone breaking device, comprising a human body auxiliary device 100 and an external shock wave device 200, wherein the human body auxiliary device 100 comprises a bed frame 15, a semicircular track 16 bridging two sides of the bed frame 15 is installed on the part of the bed frame 15, a semicircular bracket 17 driven to reciprocate between the bottom and the top of the bed frame 15 is slidably installed on the semicircular track 16, a groove 1701 is opened on the inner side of the semicircular track 16 of the semicircular bracket 17, and an air bag 18 for fixing the crotch of a patient is installed in the groove 1701.
The external shock wave device 200 is slidably mounted on the outer side of the semicircular support 17 far away from the semicircular track 16, the X-ray radiography device 300 used for detecting a calculus position is slidably mounted on the outer side of the semicircular support 17, a through hole 1701 penetrating through the inner side wall and the outer side wall of the semicircular support 17 is formed in the semicircular support 17, the X-ray radiography device 300 and the external shock wave device 200 are respectively located on one side of the semicircular support 17, and the X-ray radiography device 300 and the external shock wave device 200 are alternately matched with the through hole 1701 to detect the calculus position and crush the external shock wave.
After a patient lies on the bed frame 15, the semicircular bracket 17 positioned below the bed frame 15 is driven to rotate upwards along the semicircular track 16 to a position right above the bed frame 15, and then the semicircular bracket 17 clamps and fixes the crotch of the patient through the air bags 18 at two sides, so that the situations of inaccurate positioning of gravels and reduction of the gravels effect caused by movement of the crotch of the patient during radiography and gravels operations are avoided.
After the crotch of the patient is fixed by the air bag 18, the X-ray imaging apparatus 300 and the external shock wave apparatus 200 are operated according to the operation requirements, for example, before performing shock wave lithotripsy by the external shock wave apparatus 200, the X-ray imaging apparatus 300 is driven to rotate above the through hole 1701, the position of the stone is detected or determined again by the X-ray imaging apparatus 300, and when the position of the stone is determined, the X-ray imaging apparatus 300 is driven to move obliquely downward along the semicircular bracket 17. When the position above the through hole 1701 is set out, the external shock wave lithotripsy device is driven to move to the position above the through hole 1701 along the semicircular bracket 17, and the external shock wave lithotripsy device is debugged according to the detection result of the position of the calculus, so that the focus of the shock wave emitted by the external shock wave lithotripsy device falls on the corresponding position of the calculus to help to achieve the expected operation effect.
The through holes 1701 are provided to reduce the weight of the semicircular bracket 17, and to uniformly distribute the weight of the X-ray radiography apparatus 300 and the shock wave lithotripsy apparatus in the axial direction of the semicircular bracket 17, thereby stabilizing the semicircular bracket 17 and reducing the abrasion between the semicircular bracket 17 and the semicircular track 16.
Further, the semicircular bracket 17 on which the X-ray radiography apparatus 300 and the shock wave lithotripter are mounted is moved to the lower side of the bed frame 15 along the semicircular track 16, and then the X-ray radiography apparatus 300 and the shock wave lithotripter are stored and protected.
It is further optimized on the above embodiment that the bed frame 15 is provided with slide rails 19 at both sides along the length direction thereof, and the semicircular rails 16 are slidably mounted on the slide rails 19.
The semicircular track 16 is driven to move along the slide rail 19 to adapt to the position of the crotch of patients with different heights, and in addition, the semicircular track 16 can be moved to one end of the bed frame 15, so that the human body auxiliary device 100 can be further accommodated, and the patients can conveniently lie on the bed frame 15.
In the above embodiment, it is further optimized that the X-ray radiography apparatus 300 and the extracorporeal shock wave apparatus 200 are connected and synchronously linked through an arc plate 20 coaxial with the semicircular track 16.
The X-ray radiography device 300 and the external shock wave device 200 are connected through the arc-shaped plate 20 to synchronously move along the semicircular track 16, on one hand, the arc-shaped plate 20 keeps the distance between the X-ray radiography device 300 and the external shock wave lithotripsy device constant, and the situation that the X-ray radiography device 300, the external shock wave device 200 and the semicircular bracket 17 collide due to mechanical failure or program failure is avoided. On the other hand, since the X-ray radiography apparatus 300 and the extracorporeal shock wave apparatus 200 are linked by the arc plate 20, and only one of them needs to be in the working state at the same time, it is advantageous to simplify the structure for driving the X-ray radiography apparatus 300 and the extracorporeal shock wave apparatus 200.
It should be noted that the driving modes of the semicircular frame 17, the X-ray imaging apparatus 300 and the external shock wave apparatus 200 are selected according to actual requirements and conditions, for example, the semicircular track 16 is an electric rail with a driving function, the semicircular frame 17 is directly driven by the semicircular track 16, and similarly, the semicircular frame 17 may also be an electric rail with a driving function to drive the X-ray imaging apparatus 300 and the external shock wave apparatus 200.
The extracorporeal shock wave device 200 includes a central shock wave source 1 and a plurality of secondary shock wave sources 2 arranged around the central shock wave source 1, wherein secondary focuses of the secondary shock wave sources 2 gradually retract or are away from a direction in which a main focus of the central shock wave source 1 is located, and the secondary focuses of the secondary shock wave sources 2 do circular arc motion with the main focus of the central shock wave source 1 as a circle center.
In preparation for surgery, the central shock wave source 1 and the plurality of secondary shock wave sources 2 are adjusted such that the primary focus of the central shock wave source 1 is located in the geometric center of the stone and the primary positions of the secondary focuses of the plurality of secondary shock wave sources 2 are located on the periphery of the top layer of the stone, i.e. the plurality of secondary focuses are arranged around the primary focus.
In the early period of operation, the central shock wave source 1 and the secondary shock wave source 2 generate shock waves impacting the calculus, when the main shock waves emitted by the central shock wave source 1 reach the calculus, the calculus generates main residual waves which are diffused from the calculus to the periphery and are attenuated continuously, and simultaneously, when the secondary shock waves emitted by the secondary shock wave source 2 reach the calculus, the secondary residual waves which are diffused from the surface layer of the calculus to the center of the calculus are generated. On one hand, while the main shock wave loosens and disintegrates the whole calculus, the main residual wave collides with a plurality of secondary residual waves (the calculus at the collision part vibrates at higher frequency), so that the surface layer of the calculus is loosened and disintegrated in a large range, and the disintegration of the whole calculus is accelerated; on the other hand, the secondary shock waves generated by the plurality of secondary shock wave sources 2 are mutually collided while the surface layer of the calculus is disintegrated, so that the disintegration of the surface layer of the calculus is accelerated, and the surface layer of the calculus positioned between the adjacent secondary shock waves is disintegrated at a higher speed.
And after the outer layer of the calculus is disintegrated, the positions of the secondary focuses of the secondary shock wave sources 2 are adjusted again, so that the secondary focuses are distributed on the new outer layer of the shrunk calculus, and the calculus is disintegrated layer by layer and at multiple points again.
Through the cooperation of central shock wave source 1 and a plurality of secondary shock wave source 2, make the calculus at whole in-process that disintegrates gradually, the calculus top layer takes place to disintegrate into the calculus of fritter with higher speed, not only improved the efficiency that disintegrates to the calculus, and compare in whole disintegration, the calculus granule volume that layer-by-layer multiple spot disintegration was peeled off is small, avoided peeling off the calculus that produces big granule and lead to needing to carry out the condition of fixing a position many times and disintegrating to the calculus of a plurality of big granules, thereby operation time has been shortened greatly.
Compared with the conventional shock wave stone breaking mode, the embodiment of the invention has the advantages that the main residual wave and the plurality of secondary residual waves and the adjacent secondary residual waves collide with each other, so that the part of the stone between the collision waves vibrates at higher frequency, and the aim of accelerating the disintegration of the stone is fulfilled. In addition, the frequency of the main shock wave and the secondary shock wave is favorably reduced, so that the condition that the soft tissue injury of a patient caused by an operation is aggravated due to the adoption of the high-frequency shock wave in the operation is avoided, the pain of the patient and the discomfort after the operation are relieved, and the probability of occurrence of operation complications such as hematuria and the like is reduced.
In addition, in order to avoid the problem that the whole calculus is disintegrated into a plurality of large-particle calculi before the calculus is disintegrated layer by layer, when the calculus with a large volume is subjected to a shock wave lithotripsy operation, the shock wave emission frequency of the secondary shock wave source 2 is preferably twice as high as that of the central shock wave source 1, so that the frequency of the collision wave generated by the collision between the secondary and residual waves is twice as high as that of the collision wave generated by the collision between the secondary and residual waves and the main residual wave, and the condition that the whole calculus is too early disintegrated to generate a plurality of large-particle calculi which are difficult to clean is avoided.
And moreover, the shock wave lithotripsy device is used for a shock wave lithotripsy operation for cleaning small-size stones in time, the central shock wave source 1 and the secondary shock wave source 2 can still carry out lithotripsy in a mode of working at a lower shock wave emission frequency, and a plurality of collision waves are formed on stones through cooperation of the central shock wave source 1 and the secondary shock wave source 2, so that the disintegration speed of the stones is increased, and meanwhile, the situation that high-frequency shock waves penetrate through soft tissues to aggravate the soft tissues to be damaged due to the operation is avoided.
It should be noted that the working mode and the matching mode of the central shock wave source 1 and the secondary shock wave source 2 are adjusted according to the actual application requirements, and in order to meet the adjustment requirements of the central shock wave source 1 and the secondary shock wave source 2 in the actual application, the present invention further has the following optimized embodiments:
the invention also comprises a driving base 3 which rotates along the shock wave axis of the central shock wave source 1, the central shock wave source 1 is arranged on the driving base 3, a plurality of groups of retraction mechanisms 4 which are in one-to-one correspondence with the secondary shock wave sources 2 and are used for retracting the corresponding secondary focuses to the primary focus are arranged on the driving base 3, and the secondary shock wave sources 2 are arranged on the driving base 3 through the retraction mechanisms 4 and surround the central shock wave source 1.
The retraction mechanism 4 is used for enabling the secondary focus position to gradually approach to the center of the top layer of the stone (the direction towards the central shock wave source 1 is the top layer) along with the reduction of the volume of the stone so as to meet the requirement that large-particle stones need to be gradually stripped from the periphery to the center.
The retracting mechanism 4 comprises a sliding base 401 provided with the secondary shock wave source 2, a centripetal guide rail 402 arranged on the driving base 3, and a push-pull driving assembly 403 for driving the sliding base 401 to move along the corresponding centripetal guide rail 402, wherein the extension lines of the centripetal guide rails 402 are all perpendicular to the rotary guide moving shaft 6 line of the driving base 3.
