Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a precise gradient temperature control system and device for ultrasonic tumor treatment. Background Art

[0002] Ultrasonic treatment technology is a commonly used technology for treating tumors at present. The onset location of tumor diseases is uncertain. Tumors are relatively easy to treat in the early stage. In the late stage, tumors are not only difficult to cure, but also cause more and more physical damage. Ultrasonic treatment technology has the advantages of non-invasive, no side effects and little damage to patients, and is an ideal way to treat tumors.

[0003] Ultrasonic tumor treatment technology mainly heats the lesion of the patient through the thermal effect of ultrasound. Since the blood flow in the tumor is small and it is difficult to dissipate heat, cancer cells can be effectively killed after being heated by ultrasound without damaging normal tissues. However, when treating patients with tumors of different degrees, it is necessary to control the temperature rise range of the patient's lesion so that the tumor temperature is within a suitable range. Existing ultrasonic tumor treatment devices generally have difficulty detecting and controlling the tumor temperature inside the patient's body, and doctors need to control the ultrasound heating time based on experience, which is very demanding on the doctor's level and the operation difficulty is relatively high. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that existing ultrasonic tumor treatment devices generally have difficulty in controlling the temperature of heating the tumor, and doctors need to control the ultrasound heating time based on experience, with a large operation difficulty, and to propose a precise gradient temperature control device for ultrasonic tumor treatment.

[0005] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0006] A precise gradient temperature control device for ultrasonic tumor treatment, including a housing, on which are provided:

[0007] A central column, which is made of metal conductive material, and the central column is coaxially arranged with the housing and rotatably connected to the housing. A knob is fixedly arranged at the top end of the central column;

[0008] A metal coil, which is arranged in a spiral shape, and a contact is slidably connected to the metal coil. The contact is fixedly connected to a metal ring slidably arranged on the central column. An insulating coating is provided at the outermost end of the metal coil so that the contact is in an open circuit state when it is at the outermost end of the metal coil;

[0009] A disc spring, one end of which is fixedly arranged on the central column and the other end is fixedly arranged on the housing;

[0010] Switch assembly, the switch assembly includes a slider slidably disposed on a housing, the slider is connected to a fixed post fixedly disposed on the housing through a spring, and a starting mechanism and a one-way limiting mechanism are further provided on the slider.

[0011] Preferably, a partial cross-section of the central post located inside the housing is rectangular, and a rectangular groove matching the rectangular portion of the central post is formed in the middle of the metal ring.

[0012] Preferably, a clamping groove is formed on the metal coil, and a clamping block adapted to the clamping groove is provided on the contact head.

[0013] Preferably, the starting mechanism includes a first contact fixedly disposed at one end of the slider, an installation plate is disposed on one side of the housing close to the first contact, and a second contact corresponding to the first contact is disposed on the installation plate. The device starts when the first contact contacts the second contact.

[0014] Preferably, the one-way limiting mechanism includes a toothed ring fixedly sleeved on the central post, a plug rod with an inclined end is fixedly disposed at one end of the slider close to the toothed ring, and the plug rod is engaged with the tooth groove on the toothed ring.

[0015] Preferably, a sliding groove is disposed at the top of the housing, the slider is slidably connected to the sliding groove, the fixed post is located on one side of the sliding groove corresponding to the midpoint position of the sliding groove, and the spring is an elastic spring.

[0016] Preferably, a protective shell is disposed at the top of the housing.

[0017] Preferably, a plurality of anti-slip strips are disposed on the outer peripheral surface of the knob, and the plurality of anti-slip strips are distributed in a circumferential array.

[0018] A temperature control system includes a reading component, the reading component includes a turntable fixedly disposed on the central post, a protrusion is disposed on the turntable, a graduated disk with a plurality of notches is rotatably disposed on the housing, the protrusion is adapted to the notch, and a pointer is further disposed at the top of the rotating shaft of the graduated disk. A dial cooperating with the pointer is disposed on the protective shell.

[0019] The present invention has the following advantages compared with the prior art:

[0020] In the present invention, through the combined use of a central column, a metal coil, a metal ring, and a contact, a complete electrical path can be formed. By providing a disc spring and a knob, when the central column is rotated, the contact rises around the metal coil from the insulated end of the metal coil, and at the same time, the disc spring stores elastic potential energy. When the slider slides to one side of the central column, the device is not activated, and the insertion rod cooperates with the gear ring to limit the central column unidirectionally to prevent the central column from rotating back. After adjusting the number of turns of the central column, the device can be activated by sliding the slider, so that the insertion rod is disengaged from the gear ring. While the disc spring releases the elastic potential energy, it drives the central column to rotate until the contact slides to the end of the metal coil, at which point the device is powered off. By controlling the number of turns of the knob, the actual contact time between the contact and the metal coil can be controlled, so as to achieve the purpose of controlling the ultrasonic heating time, and thereby control the heating temperature of the ultrasonic. With the cooperation of the dial and the pointer, doctors can more easily master the generated heating time, reduce the surgical difficulty and facilitate use. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0030] Refer to Figure 1-3 , a precise gradient temperature control device for ultrasonic tumor treatment, including a housing 1, and the housing 1 is provided with:

[0031] A central column 2, the central column 2 is made of a metal conductive material, and the central column 2 is coaxially arranged with the housing 1 and rotatably connected to the housing 1. A damping is provided between the housing 1 and the central column 2, so that an external force needs to be applied to rotate the central column 2, and it rotates slowly and uniformly. A knob 9 is fixedly provided at the top end of the central column 2, and by rotating the knob 9, it is convenient to drive the central column 2 to rotate.

[0032] Refer to Figure 1-3 , a plurality of anti-slip strips 20 are arranged on the outer peripheral surface of the knob 9, and the plurality of anti-slip strips 20 are distributed in a circumferential array, which is beneficial to increasing the friction force on the outer peripheral surface of the knob 9 and reducing the situation of slipping when rotating the knob 9.

[0033] A metal coil 3, the metal coil 3 is arranged in a spiral shape, and a contact 6 is slidably connected to the metal coil 3. The contact 6 can move along the metal coil 3 while maintaining an electrical connection with the metal coil 3. The contact 6 is fixedly connected to a metal ring 7 slidably arranged on the central column 2. The metal coil 3, the contact 6, the metal ring 7 and the central column 2 form a complete electrical circuit, and a negative terminal is provided on the metal coil 3, and a positive terminal is provided at the bottom end of the central column 2. The device can be connected to an ultrasonic device through the positive terminal and the negative terminal. An insulating coating is provided at the outermost end of the metal coil 3, so that the contact 6 is in an open circuit state when it is located at the outermost end of the metal coil 3, and the power can be automatically cut off when the contact 6 moves to the bottom end of the metal coil 3.

[0034] Refer to Figure 3-4The cross-section of the part of the center column 2 located in the shell 1 is rectangular, and a rectangular groove 12 matching the rectangular part of the center column 2 is opened in the middle of the metal ring 7. When the center column 2 rotates, the metal ring 7 can rotate synchronously with the center column 2, and when the contact 6 moves along the metal coil 3, the metal ring 7 can change its position along the height direction of the center column 2.

[0035] Reference Figure 3 A card slot 13 is provided on the metal coil 3, and a card block 14 adapted to the card slot 13 is provided on the contact 6. The card slot 13 and the card block 14 cooperate with each other, which can effectively reduce the risk of the contact 6 and the metal coil 3 being separated.

[0036] Reference Figure 5 , a coil spring 4, one end of which is fixedly arranged on the central column 2, and the other end of which is fixedly arranged on the shell 1. By arranging the coil spring 4, when the central column 2 rotates, the coil spring 4 will store elastic potential energy, and when the coil spring 4 releases its elasticity, it will drive the central column 2 to rotate, thereby driving the metal ring 7 to rotate, and causing the contact 6 to slide along the metal coil 3. The operating time of the ultrasonic equipment can be controlled by the contact time between the contact 6 and the metal coil 3, thereby achieving the purpose of controlling the heating time of the patient's lesion and realizing precise temperature control.

[0037] The switch assembly 5 includes a slider 10 slidably disposed on the housing 1 , the slider 10 is connected to a fixing column 11 fixedly disposed on the housing 1 through a spring, and a starting mechanism and a one-way limiting mechanism are also provided on the slider 10 .

[0038] Reference Figure 4-6 The starting mechanism includes a first contact 15 fixedly arranged at one end of the slider 10, a mounting plate is arranged on the side of the housing 1 close to the first contact 15, and a second contact 16 corresponding to the first contact 15 is arranged on the mounting plate. When the slider 10 is slid to one side of the mounting plate, the first contact 15 and the second contact 16 will be abutted against each other under the action of the elastic force of the spring, and the device starts when the first contact 15 and the second contact 16 are in contact.

[0039] Reference Figure 5-6 The one-way limiting mechanism includes a gear ring 17 fixedly mounted on the center column 2, the tooth groove cross-section in the gear ring 17 is triangular, and a plug rod 18 with an oblique end is fixedly provided at one end of the slider 10 near the gear ring 17, and the plug rod 18 is engaged with the tooth groove on the gear ring 17. When the slider 10 is slid to one side of the gear ring 17, the plug rod 18 is inserted into the tooth groove of the gear ring 17 under the elastic force of the spring, and when the center column 2 is rotated, the gear ring 17 rotates with the center column 2, and the inclined surface of the tooth groove on the gear ring 17 is against the oblique mouth of the plug rod 18, so that the spring contracts a certain distance, which does not affect the rotation of the gear ring 17. When the gear ring 17 rotates in the opposite direction, the tooth groove plane of the gear ring 17 is against the side of the plug rod 18. At this time, the gear ring 17 is limited and cannot rotate.

[0040] Refer to Figure 4-6 , a chute 19 is provided at the top of the housing 1, and the slider 10 is slidably connected to the chute 19, which is beneficial to limit the slider 10, so that the slider 10 can only move in the length direction of the chute 19. The fixed column 11 is located on one side of the chute 19 corresponding to the midpoint position of the chute 19. The spring is an elastic spring. When the slider 10 is slid, when the slider 10 slides to the midpoint position of the chute 19, the spring force is in the maximum state. At this time, when the slider 10 is continuously slid, under the action of the spring force, the slider 10 tends to slide to the end of the chute 19.

[0041] Refer to Figure 1 , a protective shell 21 is provided at the top of the housing 1, which is beneficial to protect components such as the slider 10, the gear ring 17 and the spring.

[0042] During actual use, the central column 2 can be rotated by rotating the knob 9. The central column 2 drives the metal ring 7 to rotate and simultaneously drives the contact 6, so that the contact 6 is separated from the insulating area on the metal coil 3 and rises along the metal coil 3 to a certain height, and the disc spring 4 generates elastic potential energy. Due to the cooperation of the inserting rod 18 and the gear ring 17 at this time, the central column 2 will not rotate back. When the appropriate number of turns is rotated, the slider 10 is slid to the other end. At this time, the first contact 15 is in contact with the second contact 16, and the device power supply is turned on. The ultrasonic device emits ultrasonic waves to heat up the lesion. At this time, the inserting rod 18 is separated from the gear ring 17, and the central column 2 rotates back, and finally the contact 6 returns to the lowest insulating position of the metal coil 3. After this process is the actual ultrasonic heating time. The heating time can be controlled by setting the number of turns of rotation of the central column 2 to achieve the effect of controlling the ultrasonic temperature.

[0043] Refer to Figure 4-6 , a temperature control system includes a reading component. The reading component includes a turntable 22 fixedly arranged on the central column 2. A protrusion 23 is arranged on the turntable 22. A graduated disc 25 with a plurality of notches 24 is rotatably arranged on the housing 1. The turntable 22 and the graduated disc 25 are arranged on the same horizontal plane, and the protrusion 23 is arranged in a matching manner with the notch 24. When the central column 2 is rotated, the turntable 22 can be driven to rotate. The protrusion 23 on the turntable 22 abuts against the notch 24, so that the graduated disc 25 rotates, and when the turntable 22 rotates one circle, the graduated disc 25 rotates one degree, which is convenient for recording the number of turns of rotation of the central column 2.

[0044] Refer to Figure 4-6 , a pointer 26 is further arranged at the top of the rotating shaft of the graduated disc 25. When the graduated disc 25 rotates, the pointer 26 is driven to rotate. A dial 8 cooperating with the pointer 26 is arranged on the protective shell 21. The pointer 26 cooperating with the dial 8 can master the number of turns of rotation of the central column 2 to understand the ultrasonic power-on time, so as to achieve the purpose of controlling the ultrasonic heating temperature.

Any person skilled in the art within the technical scope disclosed by the present invention should cover within the protection scope of the present invention any equivalent replacement or change made according to the technical solution and inventive concept of the present invention.
