Referring to fig. 1-3, the femoral head necrosis washing device 200 operates according to the following principle:
the femoral head necrosis washing device 200 comprises a main body 210, wherein the main body 210 is provided with a water injection channel 211 and a water drainage channel 212; wherein, the distal end of the main body 210 is used for being inserted into the femoral head necrosis area, and the water injection channel 211 is used for injecting normal saline into the femoral head necrosis area after the main body 210 is inserted, so as to flush the femoral head necrosis area; the drainage channel 212 is used for guiding out the mixed liquid mixed with necrotic tissue after washing in the femoral head necrosis area, so that the femoral head necrosis washing device 200 has the functions of washing deep necrotic tissue of a medullary core hole by injecting normal saline into the femoral head necrosis area, guiding out the necrotic liquid such as grey white, liquefied fat and milky turbidity generated after washing, and removing focus in the femoral head necrosis area so as to relieve the action of bone marrow edema, stimulate osteoblast activity, restore blood circulation in the femoral head, promote tissue repair and relieve hip pain;
specifically, in order to enable the water injection channel 211 to introduce normal saline into the femoral head necrosis area and to guide out the flushing mixture in the femoral head necrosis area, the distal end of the main body 210 is provided with a water injection port 213 communicating with the water injection channel 211 and a water return port 214 communicating with the water discharge channel 212; since the normal saline is added to the water filling passage 211 and the mixed liquid in the water discharging passage 212 is discharged, a water inlet 215 communicating with the water filling passage 211 and a water outlet 216 communicating with the water discharging passage 212 are provided at the proximal end of the main body 210.
In summary, the femoral head necrosis flushing device 200 is convenient to operate, and can accurately clean the femoral head necrosis area, thereby being beneficial to thoroughly cleaning the deep necrotic tissue, being beneficial to bone tissue growth and shortening the treatment period; but also can avoid secondary pollution.
It should be noted that referring to fig. 1-3, the femoral head necrosis washing device 200 is used as follows:
with the aid of a C-arm machine, an operator drills a hole through a Kirschner wire and eliminates dead bones in a femoral head necrosis area, and inserts the distal end of the femoral head necrosis flushing device 200 into the femoral head necrosis area;
physiological saline is injected into the water injection channel 211 through the water inlet 215, and after passing through the water injection channel 211, the physiological saline is accurately washed by the injection port in the femoral head necrosis area; the mixed liquid mixed with necrotic tissue debris after washing is guided into the drainage channel 212 through the water return port 214 and discharged to the outside of the patient through the water discharge port 216.
In summary, the femoral head necrosis flushing device 200 directly acts on the necrosis area of the femoral head in the whole using process, thereby realizing the purpose of accelerating the treatment of femoral head necrosis, and the influence on the surrounding area in the femoral head is only in the femoral head necrosis area, thereby avoiding the influence on the intact area in the femoral head, achieving the targeted treatment on the necrosis area of the femoral head and avoiding the sequela; the necrotic tissue in the femoral head is continuously discharged through the drainage channel 212, so that the pressure in the femoral head is continuously lightened, the blood supply of the necrotic area of the femoral head is enhanced, the recovery of the femoral head is accelerated, thorough cleaning is realized, the water injection channel 211 and the drainage channel 212 are not in communication with each other, secondary pollution is prevented, the wound surface is fresh, the growth of bone tissue is facilitated, and the treatment period is shortened.
Further, referring to fig. 1-3, in the present embodiment, when the water filling port 213 and the water return port 214 are disposed, the water filling port 213 and the water return port 214 are both located at the distal end of the main body 210, so that the water filling port 213 and the water return port 214 can be both located at the distal end face of the main body 210. In other embodiments of the present utility model, one or both of the water filling port 213 and the water returning port 214 may be disposed on the outer peripheral surface of the distal end of the main body 210 according to the requirements of use.
When the water inlet 215 is provided, the physiological saline is introduced into the water injection channel 211, so that when the water inlet 215 is provided, the physiological saline is conveniently injected, and therefore, the femoral head necrosis washing device 200 further comprises a water inlet pipe 217 connected to the proximal outer circumferential surface of the main body 210, the water inlet pipe 217 is provided with the water inlet 215 communicated with the water injection channel 211, and the extending direction of the water inlet pipe 217 is perpendicular to the extending direction of the main body 210. In other embodiments of the present utility model, the water inlet 215 may be formed on the outer peripheral surface of the proximal end of the main body 210.
When the drain port 216 is provided, the drain port 216 is positioned on the proximal end surface of the main body 210 so that the mixed liquid in the drain passage 212 can smoothly flow in the drain passage 212 during the draining process. That is, in such an arrangement, the drain passage 212 penetrates the main body 210, and the smoothness of the mixed liquid in the drain passage 212 can be improved.
Further, referring to fig. 1-3, in the present embodiment, when the main body 210 is disposed, in order to facilitate the main body 210 extending into the patient, the main body 210 is cylindrical, and the water injection channel 211 and the water discharge channel 212 in the main body 210 extend along the axial direction of the main body 210. On the basis of this structure, the present embodiment adopts such a configuration that the inner diameter of the water injection channel 211 is made smaller than the inner diameter of the water discharge channel 212, that is, the inner diameter of the water discharge channel 212 is increased, in order to improve the discharging efficiency of the mixed liquid in the water discharge channel 212, in consideration that the mixed liquid in the water discharge channel 212 may be mixed with necrotic tissue, and since the fluidity of the mixed liquid may be lower than that of the physiological saline in the water injection channel 211.
As can be seen from the above description, referring to fig. 1 to 3, the water injection channel 211 is used for injecting normal saline into the femoral head necrosis area to flush the femoral head necrosis area; the drainage channel 212 is used for guiding out the mixed liquid mixed with necrotic tissue after flushing in the femoral head necrosis area, so that in order to avoid the situation that the liquid in the water injection channel 211 and the drainage channel 212 are in cross mixed flow or backflow, a first one-way valve which is used for conducting the water injection channel 211 in one way from the water inlet 215 to the water injection port 213 is arranged in the water injection channel 211, and the purpose of the drainage channel is to prevent the mixed liquid in the femoral head necrosis area from entering the water injection channel 211 to pollute the normal saline in the water injection channel 211, so that secondary pollution in the femoral head necrosis area can be avoided; outside, the situation that the water injection channel 211 is back flowed can be avoided; in the same manner as described above, in this embodiment, in addition to the structure of the first check valve, a second check valve may be provided in the drain passage 212 to conduct the drain passage 212 in one direction from the return port 214 to the drain port 216.
The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
