Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a rotor-type myoskeletal fascial release water jet power system. Background Art

[0002] Various pains in the neck, shoulders, waist, back, joints, etc. have become the second most common disease in the world after respiratory infections. Inflammation / adhesion of soft tissues (such as muscle fascia) and cartilage tissues are the main "culprits" of various pains. Local adhesions and even nodules in tissues such as musculoskeletal fascia will lead to narrowing or disappearance of tissue gaps, thereby restricting blood circulation, compressing nerves, and even limiting limb movement. Its symptoms combine pain, limited movement, and nerve dysfunction, which seriously affects the patient's physical and mental health and quality of life.

[0003] At present, the treatment methods of this disease mainly include general treatment and minimally invasive surgery. Among them, general treatment is divided into traditional Chinese medicine, physical therapy, and drug therapy, such as traditional massage, acupuncture, radiofrequency physical therapy, etc. Minimally invasive surgery mainly uses small needle knife therapy, which is a physical acupuncture separation therapy using a small needle knife similar to acupuncture silver needles. During the treatment, the doctor repeatedly and multi-point punctures the patient's myofascial pain area with a small needle knife, and uses the tip of the small needle knife to cut the inflamed or adhered tissue to achieve the purpose of separation. Anesthesia is usually not applied during the treatment, and rehabilitation training is required after the treatment.

[0004] Regarding the treatment methods mentioned above, there are many general treatment methods, but the curative effect is not good. Most of them are only temporary treatments and not fundamental treatments. The condition is very likely to relapse after stopping treatment. It can only achieve a relieving effect but cannot fundamentally solve the pathological problem of pain. The micro-needle knife rigid stripping surgery is still an invasive cutting surgery. During the operation, patients often experience severe pain and even painful shock.

[0005] In addition, the rigid cutting of the needle knife causes great stimulation to the surrounding tissues, which can easily lead to bleeding and inflammatory edema. If precise rehabilitation training is not performed after the operation, more serious adhesions will occur again at the cutting interface. Utility Model Content

[0048] like Figure 1-Figure 6As shown, the embodiment of the utility model provides a rotor-type musculoskeletal fascial release water jet power system, including a jet generating device, a jet pipeline 32, a handle 1, a needle nozzle 13, and a liquid bottle 3; the needle nozzle 13 is connected to the front end of an adapter (preferably a Luer adapter 15), and the rear end of the adapter is connected to the end of the jet pipeline 32, and the jet pipeline 32 is a flexible hose; after the jet pipeline 32 cooperates with the adapter, it passes through the hollow cavity inside the handle 1 and extends from the end of the handle 1, and the handle 1 includes a mechanical regulating device for controlling the internal pressure and water flow rate of the jet pipeline by squeezing the pipeline; a section of the pipeline between the end and the front end of the jet pipeline 32 is located in the jet generating device, and a rotor mechanism for squeezing the section of the pipeline is provided inside the jet generating device, which is used to squeeze the pipeline through the rotor to generate a vacuum inside the pipeline, pump the medical liquid in the liquid bottle 3, so that the medical liquid is sucked into the jet pipeline, and the jet is realized through the needle nozzle.

[0049] In a preferred embodiment, the handle 1 comprises an upper handle shell 16 and a lower handle shell 17 , and the upper handle shell 16 and the lower handle shell 17 are snapped together to form the handle 1 .

[0050] In a preferred embodiment, the mechanical adjustment device includes a slider 18, which has a semicircular flange in the middle of its upper end. The jet pipeline in the handle passes through the top of the semicircular flange and the inner surface of the handle opposite to the flange. The bottom end of the slider is connected to a spring, and the upper end is connected to a button 19; the button is assembled in the button slide groove of the handle, and the slider is installed in the slider groove of the handle; the handle has grooves of different depths inside, and the lower two sides of the slider have bosses that match the grooves; after the bosses are moved by the button control and positioned in different grooves, the pipe sections of the jet pipeline in the handle will be subjected to different sizes of extrusion forces due to the spring action at the bottom of the slider. See Figure 2 As shown, the needle nozzle 13 is connected to the front end of the Luer adapter 15, and the rear end of the Luer adapter 15 is connected to the end of the jet pipeline 32. After the jet pipeline 32 is matched with the Luer adapter 15, it passes through the internal hollow cavity formed by assembling the handle upper shell 16 and the handle lower shell 17, and fits tightly with the surface of the semicircular flange in the middle of the top of the slider 18, and then extends out from the circular hole at the end of the handle upper shell 16 to connect to the subsequent structure.

[0051] See also Figure 2As shown, specifically, a cylindrical boss is provided at the bottom of the slider 18, and a spring is connected by interference. Rectangular bosses are arranged at the lower part of both sides of the slider 18, and after the rectangular bosses are inserted into the rectangular grooves provided at the front end of the handle lower shell 17, they can slide in the hollow cavity inside the handle lower shell 17. Slender rectangular bosses are arranged on both sides of the top of the slider 18, and after the rectangular bosses pass through the grooves of the handle upper shell 16, they are connected with the grooves at the bottom of the button 19 by interference, so as to achieve the purpose of fastening; by pressing and pushing the button 19, the slider 18 can slide in the hollow cavity inside the handle lower shell 17 along the length direction of the handle lower shell.

[0052] Optionally, the hollow cavity inside the handle lower shell 17 has a plurality of rectangular grooves of different depths or heights arranged at intervals to cooperate with the slider 18, arranged along its length direction. Optionally, the grooves are arranged at intervals along the length direction of the handle, and their depths increase or decrease from one end of the handle to the other end. After the rectangular bosses on both sides of the lower part of the slider vertically leave the corresponding rectangular grooves downward, the slide guide can be controlled to move forward and backward by the button 19. When the rectangular bosses on both sides of the lower part of the slider are embedded in the corresponding rectangular grooves, the slider 18 can be positioned. By pushing the button 19, the jet pipeline 32 can be squeezed, thereby realizing mechanical adjustment of pressure and water flow rate.

[0053] In a preferred embodiment, the top of the button 19 is designed with a continuous small convex groove for increasing friction. Optionally, the bottom of the upper handle shell 16 near the front end has a rectangular boss, which is matched with the rectangular positioning groove provided at the front end of the lower handle shell 17 to achieve positioning. After the upper handle shell 16 and the lower handle shell 17 are matched and docked, the front end is connected to the threaded cover 14 with internal threads, and the threaded cover 14 is fastened with the external threads of the front ends of the upper handle shell 16 and the lower handle shell 17.

[0054] Among them, the center of the threaded cover 14 is provided with a hole for the needle nozzle 13 to pass through and connect with the front end of the Luer adapter 15. The Luer adapter 15 is positioned in a positioning cavity formed by the upper and lower self-connector positioning grooves formed on the inner side of the handle upper shell 16 and the handle lower shell 17 near the front end.

[0055] Preferably, the front end of the Luer adapter 15 is connected to the needle nozzle 13 by thread fastening, and the rear end of the Luer adapter 15 is designed with a cylindrical slender truncated cone to achieve interference connection with the end of the jet pipeline 32. After the needle nozzle 13 and the Luer adapter 15 are threadedly fastened, the Luer adapter 15 is matched with the front end positioning grooves of the handle upper shell 16 and the handle lower shell 17, and threadedly fastened through the threaded cover 14; after the jet pipeline 32 is connected through the Luer adapter 15, it passes through the groove structure formed by the rectangular boss at the upper end of the slider 18 and extends from the end of the handle upper shell 16 to connect to the subsequent structure, that is, it passes through the internal hollow cavity after the upper shell 16 and the handle lower shell 17 are assembled, and then extends from the circular hole at the end of the handle upper shell 16 to connect to the subsequent structure.

[0056] In the present application, through the design of the button 19 and the slider 18, the mechanical step-by-step adjustment of the pressure and the water flow rate can be controlled. After the medicine flows out of the liquid bottle 3 and enters the jet pipeline 32, since the bottom of the slider 18 is connected to the spring and the upper part is connected to the button 19, by pushing the button 19 to move, the slider 18 can be matched with different wedge-shaped grooves, and the upper end flange of the slider 18 will squeeze the jet pipeline 32, thereby adjusting the cross-sectional area of ​​the flow pipeline 32, and finally realizing real-time mechanical adjustment of the pressure and flow rate.

[0057] In the present application, the process of mechanical step-by-step adjustment of pressure and water flow rate is that the part of the jet pipeline 32 in the handle 1 passes through the gap formed by the upper shell 16 of the handle and the semicircular flange in the middle of the slider 18, and the semicircular working surface of the flange fully fits and squeezes the jet pipeline 32. The cylindrical boss at the bottom of the slider 18 is connected with a spring to provide an upward elastic force. During the movement of the slider 18 in the internal cavity of the shell 17, the elastic force provided by the spring will cause the rectangular bosses on both sides of the slider 18 to rebound upward, thereby achieving clearance fit with the rectangular grooves of different depths in the internal cavity of the shell 17. Due to the different depths of the multiple rectangular grooves, the position depth of the slider 18 after the fit is completed is also different, which will result in different gaps formed by the upper shell 16 of the handle and the semicircular flange in the middle of the slider 18, so that the semicircular working surface of the flange squeezes the jet pipeline 32 to different degrees, thereby adjusting the cross-sectional area of ​​the jet pipeline 32 and achieving mechanical step-by-step adjustment of pressure and water flow rate.

[0061] Among them, further, an eccentric wheel 28 is arranged on the upper part of the jet generating pump 2, and a slender cylinder is arranged at the front end of the eccentric wheel 28. After the cylinder passes through the circular through hole at the upper end of the pump head rear shell 25 (through the trapezoidal convex groove), it is inserted into the trapezoidal groove at the rear of the pump head upper shell 22 to achieve positioning; the disc at the rear of the eccentric wheel 28 and the rectangular groove at the rear of the pump head rear shell 25 are gap-matched to achieve connection, see Figure 5 As shown, Figure 5 The structure diagram of the rear part of the pump head rear shell 25 is shown.

[0063] Optionally, a hole is opened on the roller disk 21, and the rotor 27 is fastened thereto by threads. After the roller bearing 24, roller disk 21 and rotor 27 are integrally installed on the jet generating pump 2, the structure formed together is located in the hollow cavity formed by assembling the pump head lower shell 20 and the pump head upper shell 22.

[0064] Furthermore, in one embodiment, a pull-up slider 30 is installed in a groove on the upper shell 22 of the pump head, and the pull-up button 31 and the pull-up slider 30 are fastened together by pins. Preferably, grooves are symmetrically provided on both sides of the bottom of the upper shell 22 of the pump head, and the pull-up button 31 is installed in the groove as a whole through clearance fit, and can slide up and down in the groove. The pull-up button 31 is fastened to the pull-up slider 30 through the pin and then symmetrically installed on the upper shell 22 of the pump head. By pushing the pull-up button 31, the pull-up button 31 can be controlled to slide up and down in the groove, thereby positioning and fastening the subsequent jet pipeline 32.

[0065] Specifically, the jet pipeline 32 extends out from the circular hole at the end of the handle upper shell 16, passes through the gap formed after the pump head upper shell 22 and the rotor 27 are installed, and the pull-up slider 30 is moved up and down by pushing the pull-up button 31. The bottom of the pull-up slider 30 has a V-shaped groove aligned with the pipeline section of the jet pipeline 32 inside the jet generating pump 2, that is, the left and right ends of the pipeline section squeezed by the rotor 27 are clamped to achieve fastening and fixation. The part of the jet pipeline 32 located inside the jet generating pump 2 contacts the top of the rotor 27 and is in the interference gap between the rotor 27 and the pump head upper shell 22. After the jet pipeline 32 passes through the jet generating pump 2, the sharp plug at the end of the jet pipeline 32 is connected and fixed to the bottom slot of the liquid bottle 3.

[0066] Further, in one embodiment, an electric control device is included, the electric control device has a shell, the shell includes a pump body upper shell 12 and a pump body lower shell 8, the two are connected by threaded fastening, the DC brush motor 4 extends the shaft through the circular groove opened on the pump body lower shell 8, and is connected to the rotating shaft 26 in the jet generating pump 2; further, the DC brush motor 4 is connected to a motor controller 11, the motor controller 11 is connected to the fan 9 and the display screen 5, and is connected to an external communication interface 10 and a power supply interface 7, the display screen is preferably a touch-type LED display screen, the fan is used to dissipate heat for the DC motor, the power supply interface is used to connect an external power supply, and the communication interface is used to communicate with an external device. The DC brush motor 4, the motor controller 11, and the fan 9 are all placed in the corresponding positioning grooves of the shell; wherein, preferably, the pump body upper shell 12 is provided with a display screen 5 for pressure regulation and real-time display.

[0067] Preferably, the external communication interface 10 and the power interface 7 are installed in the grooves opened at the rear end of the lower shell 8 of the pump body to connect external leads, and the foot pad 6 is installed at the bottom of the lower shell 8 of the pump body through threaded connection.

[0068] Among them, the DC brush motor 4, motor controller 11, fan 9, external communication interface 10, power interface 7, and display screen 5 are connected by wires, and a through hole is provided at the front of the lower outer shell 8 of the pump body, and the motor shaft flange at the front end of the DC brush motor 4 passes through the through hole and is connected to the rotating shaft 26.

[0069] During installation, after the upper shell 22 of the pump head is raised by rotating the rocker 23, the jet pipeline 32 can be fixed in the pump head by pushing the pull-up button, so that the rotor 27 can squeeze and release the jet pipeline. Specifically, rotating the rocker 23 can make the upper shell 22 of the pump head rise, thereby increasing the gap between the upper shell 22 of the pump head and the rotor 27, installing the jet pipeline 32 in the gap between the upper shell 22 of the pump head and the rotor 27 and making the jet pipeline 32 contact the upper end of the rotor 27, and rotating the rocker again can make the jet pump 22 return to its original position, at which time the gap between the rotor 27 and the upper shell 22 of the pump head is reduced, and the reduced gap can make the jet pipeline 32 fully contact the rotor 27, and the arc-shaped working surface of the rotor 27 will squeeze the jet pipeline to cause deformation, and the V-shaped groove at the bottom of the pull-up slider 30 is controlled by pushing the pull-up button 31 to move up and down, and the jet pipeline 32 is clamped and clamped at both ends of the pump body 2, thereby preventing the jet pipeline 32 from loosening and moving when the equipment is running.

[0070] During the operation, the doctor first quickly connects the liquid bottle 3 filled with medical liquid to the jet pipeline 32. After the doctor holds the handle 1 and inserts the needle nozzle 13 into the calibrated point to be loosened, the DC brush motor 4 is started. Under the joint regulation of the handle button 19 and the touch screen 5, the medical liquid is pumped to realize the jet through the subsequent pipeline and the needle nozzle 13.

[0071] Specifically, during operation, the liquid bottle 3 is filled with medical liquid, the doctor holds the instrument handle 1, and after determining the release site with the assistance of the ultrasonic navigator, the needle nozzle 13 is inserted into the skin so that the nozzle tip reaches the jet position, and the DC brush motor 4 is started. The extended shaft of the DC brush motor 4 rotates to drive the rotating shaft 26 to rotate, and the rotation of the rotating shaft 26 will drive the rotating roller disk 21 to rotate, and the rotor 27 installed on the rotating roller disk 21 will rotate around the center line of the rotating roller disk 21. The extrusion force generated by the arc-shaped working surface of the rotor 27 squeezes the jet pipeline 32, which will generate a vacuum and suck the pumped medical liquid into the jet pipeline 32.

[0072] As the rotor 27 continues to move, the pumped medical liquid has entered the jet pipeline 32. At this time, the rotor 27 will squeeze the jet pipeline 32 again and push the medical liquid to the pump outlet. When the rotor 27 is separated from the jet pipeline 32, the elastically deformed pipeline part will return to its original state, forming a negative pressure, thereby inhaling new medical liquid. In this way, when the rotor 27 inside the jet generating pump 2 rotates by extending the shaft, it will periodically squeeze and release the jet pipeline 32, thereby forming a continuous and stable jet. Since the speed of the motor will affect the frequency of the periodic squeezing and releasing of the jet pipeline 32 by the arc surface of the rotor 27, the jet pressure can be controlled by setting the speed of the motor. During use, the liquid in the liquid bottle flows through the jet pipeline in the handle 1, and completes the jet after reaching the needle nozzle 13 via the Luer adapter 15. In this way, the needle nozzle 13 is inserted into the calibrated musculoskeletal fascial release site through the auxiliary guidance of the ultrasonic navigator, thereby achieving the purpose of musculoskeletal fascial release.

[0073] In the present application, after the DC brush motor 4 is started, the jet begins to be generated. The speed of the DC brushless motor 4 can be set through the display screen 5, and the frequency of the arc working surface of the rotor 27 in the jet generating pump 2 squeezing and releasing the pipeline is controlled and adjusted, thereby adjusting the flow rate of the jet in the pipeline, thereby realizing jet pressure control; in addition, the button 19 in the adjustment handle 1 is actuated so that the flange at the upper end of the slider 18 and the semicircular flange in the middle of the slider 18 squeeze the pipeline, which can control the cross-sectional area of ​​the pipeline, thereby controlling the jet pressure, thereby realizing pressure regulation of medical solution injection. The display screen 5 located on the upper shell 12 of the pump body can display the pressure gear and working status of the equipment in real time, so that the doctor can observe and adjust, thereby improving the accuracy of treatment and the convenience of operation.

[0074] In a preferred embodiment, the needle nozzle 13 is designed as a flexible rigid guide needle structure with a diameter of ≤0.3 mm. When the surgeon holds the handle 1 to insert the needle, the access trauma caused during the treatment process is small, and the bleeding of the wound is also small. Water jet separation has a selective separation characteristic, and the jet pressure can be adjusted to effectively loosen the muscle, bone and fascia tissue without causing excessive damage to the surrounding tissue.

[0075] The utility model is a special surgical tool for musculoskeletal fascial release. After the ultra-minimally invasive needle nozzle reaches the calibrated lesion point, the pressure injection of the drug is controlled by the button 19 on the handle 1 and the display screen on the shell. The operating physician does not need to adjust the needle holding gesture to complete the drug injection, and the needle position will not change. The positioning accuracy of musculoskeletal fascial release can be improved, and the problem of closed surgical approach is solved.

[0076] During the jetting process of the system of the utility model, except for the disposable consumables, there is no direct contact with the medicine liquid and the water flow. Only the disposable consumables need to be replaced for each treatment, which can realize the requirements of surgical sterilization and disposableness, and can effectively meet the safety and sterility requirements of clinical treatment operations.

[0077] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model.

[0078] Therefore, no matter from which point of view, the embodiments should be regarded as illustrative and non-restrictive, and the scope of the present invention is limited by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

[0079] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
