[0001] The utility model belongs to the technical field of medical equipment, in particular to a perianal abscess puncture device. Background Art
[0002] Anorectal abscess is a common perianal infectious disease. Once diagnosed, immediate surgical drainage is required to quickly control the infection, alleviate symptoms, and avoid further spread of the infection, which may affect anal function and even be life-threatening.
[0003] There are two main drainage methods currently used. One is to use a scalpel to cut an incision in the abscess and squeeze out the pus. The other is to use a syringe to puncture and extract the pus inside.
[0004] Although the above two methods can solve the drainage problem of perianal abscess very well, in actual operation, due to many special clinical situations, for example, for patients with advanced malignant tumors and blood system diseases, as well as elderly patients with many underlying diseases who cannot tolerate surgery, incision and drainage surgery is risky and is not applicable. Syringe puncture drainage requires repeated extraction to avoid puncturing the external anal sphincter, which is cumbersome to operate and the patient's physical sensation is poor. Both of the above methods have certain inconveniences. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] like Figures 1 to 6 As shown, an embodiment of the utility model provides a perianal abscess puncture device, comprising: a puncture needle 1, at least two slots 2 are provided on the side of the needle stem of the puncture needle 1 close to the needle tip, a pipette 3, the outer diameter of the pipette 3 is smaller than the inner diameter of the puncture needle 1, and the puncture needle 1 and the pipette 3 are slidably matched, and a number of locking members corresponding to the slots 2 are installed in a pre-opened installation groove on the pipette 3, and the puncture needle 1 and the pipette 3 are locked by the locking members.
[0028] The working principle and beneficial effects of the above technical solution are as follows: when in use, first pull out the pipette 3 a distance relative to the puncture needle 1 so that the end of the pipette 3 close to the needle tip is immersed in the interior of the puncture needle 1 without affecting the puncture of the needle tip, and then perform puncture until the tube body of the puncture needle 1 at the position of the slot 2 is immersed in the abscess, then pinch the part of the puncture needle 1 that has not penetrated into the abscess with one hand, and push the pipette 3 in the direction close to the abscess with the other hand, push the pipette 3 into the deep of the abscess until the protruding part of the locking piece is embedded in the corresponding slot 2, and lock the pipette 3 relative to the puncture needle 1. At the same time, the protruding part of the locking piece can be against the inner wall of the epidermis near the wound where the abscess is punctured, so as to prevent the device from falling out of the wound formed by puncturing the abscess, thereby performing safe and efficient continuous drainage.
[0029] In one embodiment, the locking member includes an elastic connecting strip 4 , one end of which is fixedly connected to the pipette 3 , and the other end of the connecting strip 4 is fixedly connected to a protrusion 5 , the length and width of the protrusion 5 are both smaller than the slot 2 .
[0030] The working principle and beneficial effects of the above technical solution are as follows: when puncture is required, the pipette 3 is first pulled outward for a distance relative to the puncture needle 1, so that the end of the pipette 3 close to the needle tip is immersed in the interior of the puncture needle 1 without affecting the puncture of the needle tip. During this process, the protrusion 5 is squeezed by the inner wall of the puncture needle 1 near the slot 2, and is separated from the slot 2, and the connecting strip 4 is squeezed and bent, so that the protrusion 5 is embedded in the corresponding guide groove 6 and slides therein.
[0031] In one embodiment, the inner wall of the puncture needle 1 is provided with guide grooves 6 corresponding in number to the protrusions 5 , and each protrusion 5 is slidably matched with the corresponding guide groove 6 .
[0032] The working principle and beneficial effects of the above technical solution are as follows: the setting of the guide groove 6 limits the moving trajectory of the protrusion 5 and the pipette 3, so that the pipette 3 can only move back and forth along the groove direction of the guide groove 6.
[0033] In one embodiment: it also includes a first adjusting part, the first adjusting part includes a first driving ring 7 and a first limiting ring 8, the first limiting ring 8 is fixedly connected to the side of the puncture needle 1 away from the needle tip 1, the first driving ring 7 is rotatably connected to the first limiting ring 8, an external thread is provided on part of the tube body of the pipette 3, and an internal thread matching the external thread is provided on the inner side of the first driving ring 7.
[0034] The working principle and beneficial effects of the above technical solution are as follows: after the puncture is completed, one hand pinches the part of the puncture needle 1 that has not penetrated the abscess, and the other hand rotates the first driving ring 7, and with the cooperation of the guide groove 6, drives the pipette 3 to move, so that the inner wall of the pipette 3 and the puncture needle 1 slide relative to each other, and the pipette 3 can be extended deep into the abscess to perform drainage work. At the same time, the pipette 3 is deeper than the needle tip of the puncture needle 1, which can avoid unnecessary damage to the patient's body caused by the needle tip, further improving the safety of the device.
[0035] In one embodiment, a plurality of first anti-slip ribs 9 arranged in parallel are fixedly connected to the outer surface of the first driving ring 7 .
[0036] The working principle and beneficial effects of the above technical solution are as follows: the provision of the first anti-slip rib 9 increases the friction between the first drive ring 7 and the worker's hand, and improves the stability when the first drive ring 7 is moved or rotated.
[0037] In one embodiment: it also includes a second adjustment part, the second adjustment part includes a second driving ring 10, a second limiting ring 11 and a driving rod 12, the second limiting ring 11 is fixedly connected to the side of the puncture needle 1 away from the needle tip, the second driving ring 10 is rotatably connected to the second limiting ring 11, the driving rod 12 is fixedly installed on the outer surface of the pipette 3, a spiral groove 13 is opened on the inner side of the second driving ring 10, and the driving rod 12 is slidably matched with the spiral groove 13.
[0038] The working principle and beneficial effects of the above technical solution are as follows: after the puncture is completed, one hand pinches the part of the puncture needle 1 that has not penetrated the abscess, and the other hand rotates the second drive ring 10, so that the spiral groove 13 and the drive rod 12 slide relative to each other, pushing the pipette 3 and the puncture needle 1 to slide relative to each other. Under the limiting effect of the guide groove 6, the pipette 3 is able to extend deep into the abscess to perform drainage work. At the same time, the pipette 3 is deeper than the needle tip of the puncture needle 1, which can avoid unnecessary damage to the patient's body caused by the needle tip, further improving the safety of the device.
[0039] In one embodiment, a plurality of second anti-slip ribs 14 arranged in parallel are fixedly connected to the outer surface of the second driving ring 10 .
[0040] The working principle and beneficial effects of the above technical solution are as follows: the provision of the second anti-slip rib 14 increases the friction between the second drive ring 10 and the worker's hand, and improves the stability of moving or rotating the second drive ring 10 .
[0041] In one embodiment, a drainage tube 15 is installed at one end of the pipette 3 away from the needle tip of the puncture needle 1 .
[0042] The working principle and beneficial effects of the above technical solution are as follows: the provision of the drainage tube 15 facilitates the safe and continuous drainage of pus.
[0043] Working principle and usage process:
[0044] First, the pipette 3 and the drainage tube 15 are connected and fixed. In the initial state, the protrusion 5 on the pipette 3 is located in the corresponding slot 2. At this time, the pipette 3 is pulled away from the needle tip relative to the puncture needle 1 until the needle tip is not hindered by the pipette 3, and the puncture work can be successfully completed. During the pulling process, the protrusion 5 is disengaged from the corresponding slot 2 and is squeezed by the inner wall of the needle tube of the puncture needle 1, driving the elastic connecting strip 4 to undergo elastic deformation, and the protrusion 5 is embedded in the corresponding guide groove 6 and slides therein.
[0045] During puncture, the needle tip of the puncture needle 1 is slowly inserted into the abscess until the two slots 2 for the protrusion 5 to pop out of the puncture needle 1 are immersed in the abscess. Then, the first drive ring 7 or the second drive ring 10 is slowly twisted to slowly push the pipette 3 in until the protrusion 5 moves to the corresponding slot 2 position and is embedded therein under the elastic force of the elastic connecting strip 4. The two protrusions 5 protruding to the outside of the puncture needle 1 can prevent the needle tube from falling out of the abscess during drainage. The pipette 3, which is deeper than the needle tip of the puncture needle 1, can prevent the puncture needle tube from stabbing the patient during continuous drainage.
[0046] After the drainage is completed, the first drive ring 7 or the second drive ring 10 is twisted in the opposite direction to slowly withdraw the pipette 3. During this process, the residual pus in the shallow layer of the abscess can be sucked out. At the same time, the protrusion 5 is disengaged from the corresponding slot 2 and no longer forms an obstacle, so that the puncture needle 1 can be smoothly pulled out.
[0047] The utility model adopts the technical means of cooperating with the puncture needle 1 and the pipette 3. First, the puncture needle 1 is used for puncture, and then the pipette end of the pipette 3 is pushed into the deep of the abscess through the channel inside the puncture needle 1, and then the protrusion 5 is used for limiting to prevent the device from falling off during the continuous drainage process, so that the device can continue to drain while eliminating the risk of the external anal sphincter being pierced by the needle tip of the puncture needle 1. To a certain extent, the technical problems existing in the two existing methods are overcome, thereby achieving minimally invasive, safe and efficient technical effects.
