Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a handle structure for a medical irrigator, which is particularly suitable for solving the problem of easy blockage of the internal channel of the handle. Background Technology

[0002] In clinical medical procedures, medical irrigators are commonly used medical devices, widely applied in surgical procedures for wound cleaning, cavity irrigation, and suction. The handle, a key component, contains internal channels for fluid flow. To minimize contamination, two channels are typically provided: one connects the irrigation fluid supply device to the irrigation head for fluid transfer; the other is used to absorb blood, tissue fluid, and other contaminants generated during surgery, removing them from the patient's body.

[0003] However, existing medical irrigator handles are prone to clogging during use. This is mainly due to the following reasons: First, some sections of the inner diameter of the channel are narrow or have excessively small corner angles. When contaminants contain small amounts of impurities, tissue debris, or viscous blood clots, they tend to accumulate in these areas, gradually forming a blockage. Second, after use, residual irrigating fluid dries inside the channel, forming solid residues that can easily cause blockages when used again.

[0004] Blockage of the irrigation channel not only affects the normal use of the irrigation device and reduces irrigation and suction efficiency, but can even prolong treatment time during surgery, posing safety hazards. Therefore, there is an urgent need for a medical irrigation device handle that can effectively solve the problem of easy blockage of the internal channel. Utility Model Content

[0005] The purpose of this invention is to provide a clog-resistant medical irrigator handle. This invention has the advantages of a large channel, easy cleaning, and clog prevention.

[0006] The technical solution of this utility model is as follows: A medical rinsing device handle for preventing blockage, comprising a handle body, wherein the handle body is provided with a transverse channel and a longitudinal channel, the axis of the transverse channel intersecting perpendicularly with the axis of the longitudinal channel to form a T-shaped intersection, and control holes are provided on the cross-sections of the transverse channel and the longitudinal channel, the control holes extending through both sides of the handle body, and control buttons are installed on the control holes, the control buttons controlling the opening and closing of the transverse channel and the longitudinal channel.

[0007] In the aforementioned anti-clogging medical irrigator handle, for ease of disassembly and installation, the diameter of the channel openings of the transverse and longitudinal channels is smaller than the diameter of the control hole.

[0008] In the aforementioned anti-clogging medical irrigator handle, the control button includes a button sleeve, which is disposed in the longitudinal control hole and the transverse control hole. A left button is fixedly installed at one end of the button sleeve, and a threaded button buckle is provided at the other end. A reset spring and a button core are sequentially installed inside the button sleeve. A right button is provided at the end of the button core. The left button and the right button are respectively located on the two sides of the handle body.

[0009] In the aforementioned anti-clogging medical irrigator handle, in order to fit the button sleeve and the button core together, the button sleeve has through holes running vertically through its wall, and a protruding clip is provided on the inner side of the button sleeve wall, with the protruding clip located in the middle of the two through holes; the button core has a groove on its circumferential surface, and the protruding clip is slidably connected in the groove.

[0010] In the aforementioned anti-clogging medical irrigator handle, in order to enable precise control, the button core is provided with a channel hole, the channel hole being the same size as the through hole, and the protrusion sliding to the end of the groove, where the channel hole coincides with the through hole.

[0011] In the aforementioned anti-clogging medical irrigator handle, to facilitate suction and prevent clogging, one end of the transverse channel is provided with a suction interface, one end of the longitudinal channel is provided with a rinsing interface, and the other end forming the T-shaped junction is provided with a rinsing tube mounting threaded hole.

[0012] In the aforementioned anti-clogging medical irrigator handle, for the convenience of doctors, the handle body is gun-shaped. The edge of the control button on the horizontal channel is flush with the inner wall of the T-shaped intersection. The control button on the vertical channel is located away from the T-shaped intersection, and the distance from the T-shaped intersection is less than 1 / 2 of the total length of the vertical channel. During operation, the control button is pressed with the thumb to control the opening and closing of the horizontal and vertical channels.

[0013] Compared with the prior art, this utility model sets up a T-shaped intersecting horizontal and vertical channel, and sets control buttons on the cross-section of the two channels. The two control buttons control the opening and closing of the horizontal and vertical channels respectively. The two channels share a small section of the channel, which increases the inner diameter of the channel without increasing the size of the handle body. The larger channel prevents blockage. At the same time, the suction channel is designed as a straight line to make the suction smoother and further prevent blockage.

[0014] Furthermore, by setting the diameter of the opening of the transverse channel and the longitudinal channel to be smaller than the diameter of the control hole, a detachable control button is installed inside the control hole. The control button has a simple structure, few parts, and is easy to disassemble and clean.

[0015] In summary, this utility model has the characteristics of simple structure, anti-clogging, and convenient rinsing. Attached Figure Description

[0023] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0024] Example 1.

[0025] A clog-resistant medical flushing device handle, such as Figure 1-4 As shown, the device includes a handle body 1, which is T-shaped. The handle body 1 has a horizontal channel 11 and a vertical channel 12 inside. One end of the horizontal channel 11 is connected to a mounting threaded hole 5, and the other end is connected to a suction interface 3. One end of the vertical channel 12 is connected to a rinsing interface 4.

[0026] The axis of the transverse channel 11 and the axis of the longitudinal channel 12 intersect perpendicularly to form a T-shaped junction; a transverse control hole 110 is provided on the cross-section of a section of the transverse channel 11 that connects to the suction interface 3; a longitudinal control hole 120 is provided on the cross-section of the longitudinal channel 12; both the transverse control hole 110 and the longitudinal control hole 120 penetrate through both sides of the handle body 1, and a detachable control button 2 is sealed and installed on both the transverse control hole 110 and the longitudinal control hole 120, the control button 2 controlling the opening and closing of the transverse channel 11 and the longitudinal channel 12.

[0027] The diameter of the channel openings of the transverse channel 11 and the longitudinal channel 12 is smaller than the diameter of the control holes of the transverse control hole 110 and the longitudinal control hole 120.

[0028] The edge of the transverse control hole 110 is flush with the inner wall of the T-shaped intersection, and the longitudinal control hole 120 is located away from the T-shaped intersection, and the distance between it and the T-shaped intersection is less than 1 / 2 of the total length of the longitudinal channel 12.

[0029] The control button 2 includes a button sleeve 21, which is disposed in the longitudinal control hole 120 and the transverse control hole 110. A left button 22 is fixedly installed at one end of the button sleeve 21, and a button buckle 23 is connected to the other end. A return spring 24 and a button core 25 are installed in sequence inside the button sleeve 21. A right button 26 is provided at the end of the button core 25. The left button 22 and the right button 23 are respectively located on the two sides of the handle body 1.

[0030] The button sleeve 21 has through holes 211 extending through its upper and lower walls, and a protrusion 212 is provided on the inner side of the button sleeve 21 wall; the button core 25 has a groove 252 on its outer circumferential surface, the direction of the groove 252 is along the axial direction of the button core 25, and the protrusion 212 is slidably connected in the groove 252.

[0031] The button core 25 is provided with a channel hole 251, which is the same size as the through hole 211. The protrusion 212 slides to the end of the groove 252, and the channel hole 251 coincides with the through hole 211.

[0032] In use, first install the irrigation tube 6 suitable for surgery into the mounting threaded hole 5, then connect the suction port 3 and the irrigation port 4 to the water hoses respectively, and connect the two water hoses to the negative pressure suction device tank.

[0033] When the wound needs to be rinsed, press and hold the right button 26 on the control button 2 at the longitudinal channel 12 to slide the convex card 212 to the end of the groove 252, so that the channel hole 251 coincides with the through hole 211. Figure 5The flushing fluid flows through the longitudinal channel 12, through hole 211, channel hole 251, and the common transverse channel to the flushing pipe 6; after flushing is completed, the right button 26 is released, and under the action of the reset spring 24, the button core 25 moves, the channel hole 251 and the through hole 211 do not coincide, and the button core 25 blocks the longitudinal channel 12.

[0034] When it is necessary to remove sewage, press and hold the right button 26 on the control button 2 at the transverse channel 11, so that the convex clip 212 slides to the end of the groove 252, and the channel hole 251 coincides with the through hole 211, as shown. Figure 6 Wastewater flows from flushing pipe 6 through a shared transverse channel, through hole 211, channel hole 251, and transverse channel 11 into a negative pressure waste liquid tank. Upon completion of the suction action, releasing the right button 26 causes the button core 25 to move under the action of the return spring 24. The channel hole 251 and through hole 211 no longer coincide, and the button core 25 blocks the transverse channel 11. During wastewater suction, because the wastewater contains small amounts of impurities, tissue debris, or viscous blood clots, the suction channel is designed in a straight line to prevent clogging.
