Description
Technical Field
[0001] This utility model relates to the field of disposable water-cooled microwave thermocoagulation ablation needle technology, specifically a sterile disposable water-cooled microwave thermocoagulation ablation needle. Background Technology
[0002] Disposable water-cooled microwave thermocoagulation ablation needles are single-use medical devices used in medical settings such as tumor treatment. Controlled by a handle, they contain a needle that emits microwaves. The microwave thermal effect causes tumor tissue to heat up, coagulate, and necrotize. During operation, a water-cooling system lowers the needle temperature, preventing excessive heat damage to surrounding healthy tissue. This allows for precise and efficient ablation of diseased tissue, providing patients with a minimally invasive treatment option. However, existing disposable water-cooled microwave thermocoagulation ablation needles cannot guarantee sterility before use, allowing bacteria from the environment to easily adhere to them. Manual disinfection by medical personnel can result in uneven application of disinfectant and missed areas, making it difficult to completely remove bacteria from the ablation needle. Utility Model Content
[0003] The purpose of this invention is to provide a sterile, disposable water-cooled microwave thermocoagulation ablation needle. Using this device solves the problem that bacteria can easily adhere to existing ablation needles during operation, making it difficult to completely remove bacteria.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a sterile disposable water-cooled microwave thermal coagulation ablation needle, comprising a handle, a needle head disposed inside the handle, a tube groove opened inside the handle, a cleaning component for cleaning the needle head fixedly installed on the outer surface of the handle, and a wiping component movably disposed at one end of the handle, the wiping component being located on the outer surface of the arc groove;
[0005] The cleaning assembly includes a liquid reservoir fixedly installed on the outer surface of the handle. The liquid reservoir has a liquid storage chamber inside. An L-tube is fixedly installed at one end of the liquid reservoir, with one end of the L-tube connected to the inside of the liquid storage chamber and the other end of the L-tube connected to a tube groove. A push plate is movably installed on the inner wall of the liquid storage chamber. A long rod is fixedly installed on one side of the push plate. A pressure plate is fixedly installed at one end of the long rod, and a T-shaped block is fixedly installed on the upper surface of the long rod.
[0006] Furthermore, the wiping assembly includes a sleeve disposed on the outer surface of the handle. The inner wall of the sleeve has an inner groove, and the inner wall of the inner groove has a transverse groove. A ball is movably disposed in the transverse groove. A sponge is fixedly installed on the inner wall of the inner groove. A sterile cloth is fixedly installed inside the sponge. A slider is slidably disposed on the inner wall of the transverse groove. A sleeve is fixedly installed on one side of the slider. The outer surface of the sleeve is in contact with the sterile cloth. The sleeve is located on the outer surface of the needle. A limiting plate is fixedly installed at one end of the sleeve, and one side of the limiting plate is in contact with one end of the sleeve.
[0007] Furthermore, the handle has an integrated module inside, and the surface of the handle has a sliding groove and an arc groove. A rotating disk is movably installed inside the arc groove and is movably fitted onto the outer surface of the needle. The outer surface of the handle has a T-shaped groove that matches a T-shaped block. One end of the handle has an installation groove, and one end of the installation groove has a round hole. The installation groove has a connecting hole inside and is connected to the installation groove.
[0008] Furthermore, a slide rod is movably installed inside the slide groove, an anti-slip pad is fixedly installed on the upper surface of the slide rod, and the other end of the slide rod is movably sleeved on the outer surface of the needle.
[0009] Furthermore, one side of the rotating disk is provided with an annular groove, a V-shaped groove, a pinhole, and a water channel. The pinhole is connected to the V-shaped groove and penetrates through the other side of the rotating disk. The pinhole is located at the center of the V-shaped groove. The water channel is connected to the slide rod. A positioning plate is fixedly installed on the outer surface of the rotating disk. One end of the tube channel is located above the V-shaped groove. The pinhole is movably connected to the needle.
[0010] Furthermore, a groove is provided on the outer surface of the handle, and a fixing rod is fixedly installed on the inner wall of the groove. The rotating disk is located inside the groove, and the fixing rod is slidably connected to the annular groove.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] This invention proposes a sterile, disposable water-cooled microwave thermocoagulation ablation needle. When the ablation needle is needed, the pressure plate is pressed down beforehand. When the pressure plate is pressed all the way down, the ablation needle is hung up so that the needle tip is perpendicular to the ground. At this time, the squeezed disinfectant flows through the tube groove into the V-shaped groove, and then flows again through the V-shaped groove into the water flow trough. Since the water flow trough is connected to the connecting hole, and the connecting hole is connected to the round hole, the disinfectant flows onto the surface of the needle tip to disinfect the needle tip. Because the round holes are evenly distributed, the liquid also flows evenly onto the needle tip. The surface of the needle tip is then cleaned. When using the ablation needle, the limiting disc is pulled to move it out of the cannula. Since the inner wall of the sleeve does not contact the outer surface of the needle, the needle will not be damaged as the sleeve moves. When the sleeve is removed from the cannula, the squeezed sponge and sterile cloth will come closer together to wrap the needle. Since the cannula and one end of the handle are installed by rotating the thread, the cannula must also be rotated when it is removed. At this time, the rotating cannula will wipe the needle, thus improving the effect of cleaning bacteria from the needle. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] According to one embodiment of the present invention, Figures 1-7 A sterile disposable water-cooled microwave thermal coagulation ablation needle includes a handle 1, a needle 4 is provided inside the handle 1, a tube groove 15 is opened inside the handle 1, a cleaning component 3 for cleaning the needle 4 is fixedly installed on the outer surface of the handle 1, and a wiping component 2 is movably provided at one end of the handle 1, the wiping component 2 is located on the outer surface of the arc groove 14.
[0023] Cleaning component 3 includes a liquid reservoir 31 fixedly mounted on the outer surface of handle 1. The liquid reservoir 31 has a liquid storage chamber 32 inside. An L-tube 33 is fixedly mounted at one end of the liquid reservoir 31, with one end connected to the inside of the liquid storage chamber 32 and the other end connected to a tube groove 15. A push plate 34 is movably mounted on the inner wall of the liquid storage chamber 32. A long rod 35 is fixedly mounted on one side of the push plate 34, with a pressure plate 36 fixedly mounted at one end of the long rod 35. A T-shaped block 37 is fixedly mounted on the upper surface of the long rod 35. When needed... When using the handle 1, pressing the pressure plate 36 beforehand allows the push plate 34 to squeeze the liquid inside the liquid storage chamber 32, allowing the liquid to enter the tube groove 15 through the L tube 33. The disinfectant will then gradually flow through the tube groove 15 to the outer surface of the needle 4. When using the handle 1, simply remove the wiping component 2 from the surface of the needle 4. As the wiping component 2 is removed, it can wipe the needle 4 to remove the disinfectant, thus further improving the sterility of the handle 1.
[0024] The wiping assembly 2 includes a sleeve 21 disposed on the outer surface of the handle 1. An inner groove 22 is formed on the inner wall of the sleeve 21, and a transverse groove 23 is formed on the inner wall of the inner groove 22. A retaining ball 24 is movably disposed in the transverse groove 23. A sponge 25 is fixedly installed on the inner wall of the inner groove 22, and a sterile cloth 26 is fixedly installed inside the sponge 25. A slider 28 is slidably disposed on the inner wall of the transverse groove 23. A sleeve 27 is fixedly installed on one side of the slider 28. The outer surface of the sleeve 27 is in contact with the sterile cloth 26. The sleeve 27 is located on the outer surface of the needle 4. A limiting disc 29 is fixedly installed at one end of the sleeve 27, and one side of the limiting disc 29 is attached to… When the handle 1 is needed to operate, grasp the limiting plate 29 at one end of the sleeve 21 and pull the limiting plate 29 to allow the sleeve 27 to gradually detach from the inside of the sleeve 21. When the sleeve 27 gradually detaches from the inside of the sleeve 21, the sponge 25 and sterile cloth 26, which have been compressed into an arc shape, will return to their original positions and thus come into contact with the needle 4. Since the sleeve 21 and the handle 1 are installed by rotating the thread, when disassembling the sleeve 21, rotate the sleeve 21. At this time, the rotating sleeve 21 and the sterile cloth 26 that are in contact with the needle 4 will clean the disinfectant on the surface of the needle 4.
[0025] The handle 1 has an integrated module 11 inside. The surface of the handle 1 has a sliding groove 13 and an arc groove 14. A rotating disk 12 is movably installed inside the arc groove 14. The rotating disk 12 is movably fitted on the outer surface of the needle 4. The outer surface of the handle 1 has a T-shaped groove 16, which is adapted to a T-shaped block 37. One end of the handle 1 has a mounting groove 17, and one end of the mounting groove 17 has a round hole 171. The mounting groove 17 has a connecting hole 19 inside, which is connected to the mounting groove 17. The T-shaped block 37 can be moved stably through the T-shaped groove 16. By pushing the sliding rod 18, the needle 4 can be used to puncture some tumors with hard outer skin. Finally, the disinfectant can flow to the outer surface of the needle 4 through the round hole 171 and the sliding rod 18.
[0026] The slide 13 has a movable slide rod 18 inside. An anti-slip pad 181 is fixedly installed on the upper surface of the slide rod 18. The other end of the slide rod 18 is movably sleeved on the outer surface of the needle 4. By moving the slide rod 18, the needle 4 can be moved, thereby piercing some hard tumor epidermis. The anti-slip pad 181 can prevent the slide rod 18 from slipping.
[0027] A rotating disk 12 has an annular groove 121, a V-shaped groove 122, a pinhole 123, and a water channel 124 on one side. The pinhole 123 is connected to the V-shaped groove 122 and extends through the other side of the rotating disk 12. The pinhole 123 is located at the center of the V-shaped groove 122. The water channel 124 is connected to the connecting hole 19. A positioning plate 125 is fixedly installed on the outer surface of the rotating disk 12. One end of the tube groove 15 is located above the V-shaped groove 122. The pinhole 123 is movably connected to the needle 4. When the venom enters the surface of the V-shaped groove 122 through the inside of the tube groove 15, the disinfectant will gradually flow into the water flow trough 124 because the V-shaped groove 122 is conical. Since the water flow trough 124 is connected to the connecting hole 19, and the connecting hole 19 is connected to the round hole 171, and one end of the round hole 171 is aligned with the outer surface of the needle 4, the liquid will flow through the water flow trough 124, the connecting hole 19, and the round hole 171 in sequence and finally flow to the outer surface of the needle 4 to disinfect the needle 4.
[0028] The outer surface of the handle 1 has a groove 141, and a fixing rod 142 is fixedly installed on the inner wall of the groove 141. The rotating disk 12 is located inside the groove 141. The fixing rod 142 is slidably connected to the annular groove 121. The rotating disk 12 can be rotated stably through the annular groove 121 and the fixing rod 142. When the needle 4 still cannot pierce the tumor epidermis, the rotating disk 12 can be rotated to make the rotating disk 12 rotate with the needle 4. At this time, the rotation of the rotating disk 12 plus the push of the slide rod 18 can improve the efficiency of piercing the tumor epidermis.
[0029] Specifically, when the ablation needle is needed, the needle 4 is held perpendicular to the ground, and then the pressure plate 36 is pressed, causing the pressure plate 36 to move along with the long rod 35 and the push plate 34. The moving push plate 34 then squeezes the disinfectant inside the reservoir 32 into the L-tube 33. Due to gravity, the liquid flows through the tube groove 15 to the surface of the V-shaped groove 122, and the disinfectant flows along the V-shaped groove 122 into the water trough 124. Because the water trough 124, the connecting hole 19, and the round hole 171 are connected, the disinfectant flows from one end of the round hole 171 to the outer surface of the needle 4. Since the round holes 171 are evenly distributed at one end of the handle 1, the disinfectant also flows evenly onto the surface of the needle 4. The disinfectant flowing from the round holes 171 gradually fills the surface of the needle 4. When the needle 4 needs to be used after disinfection for a period of time, the sleeve 27 is pulled out from inside the sleeve 21. The compressed sponge 25, compressed by the sleeve 27, is reset. The reset sponge 25, along with the sterile cloth 26, adheres to the needle 4. At this point, the two sets of sterile cloths 26 will wrap around the needle 4. Finally, when removing the cannula 21, it needs to be rotated. At this time, the rotating cannula 21 will rotate simultaneously with the sponge 25 and the sterile cloth 26, thereby wiping the disinfectant on the surface of the needle 4. When the needle 4 encounters a tumor with a hard epidermis, the sliding rod 18 can be rotated to move the needle 4. If pushing the sliding rod 18 still cannot pierce the epidermis, the rotating disk 12 can be rotated to rotate the needle 4 together. At this time, pushing the sliding rod 18 again can pierce the tumor with a hard epidermis, allowing for subsequent work. Thus, the needle 4 is disinfected by the cooperation of the cleaning component 3 and the wiping component 2, thereby improving the effectiveness of the needle 4 in cleaning bacteria.
