As shown in fig. 1 to 6, the intra-osseous lesion 100 scraping component for minimally invasive surgery is used for scraping the lesion 100 by matching with a base hole 10, the base hole 10 penetrates from the outside to the lesion 100, the component comprises a scraper 1, a knife handle 11 and a knife head 12 fixed with the knife handle 11 at an angle, and the knife head 12 is provided with scraping teeth 121; the guide part 2 comprises a support main body 21, the cross section of the support main body 21 is the same as that of the base hole 10 in shape and size, and part of the support main body is inserted into the base hole 10, a plurality of guide holes 210 are formed in the support main body 21 along the length direction of the base hole 10, and the cutter handle 11 of the scraper 1 is inserted into the guide holes 210.
The shape of the focus 100 in the bone is mainly divided into two shapes of approximate round or strip, when the shape of the focus 100 is approximate round, the hole pattern of the base hole 10 is also round, and the cross section of the guide part 2 is consistent with the base hole 10 and is also round.
During operation, the head of the scraper 1, the camera and the like is not convenient to pass through the base hole 10 by a tool of the guide hole 210 according to actual conditions. And then the guide part 2 is inserted into the base hole 10, and the guide part 2 is partially remained outside the base hole 10, when the guide part 2 is inserted, the handle parts of the scraper 1, the camera and the like are firstly aligned to the guide hole 210, and the handle parts are ensured to penetrate into the guide hole 210. Finally, the lesion 100 is scraped off by the rotary scraper 1. As shown in fig. 2, the part of the rotary guide part 2 reserved outside the base hole 10 is rotated, the position of the guide hole 210 can be adjusted by rotating the whole guide part 2, and the guide hole 210 drives tools required by operations such as a scraper 1, a camera and a washing tube to rotate and change the position, so that the action position of the equipment is further enlarged, the operation range can be ensured to relate to the whole focus 100, the whole focus 100 can be completely scraped under the minimally invasive condition, and the operation is completed.
When the shape of the lesion 100 is close to a long strip, the hole pattern of the base hole 10 is also long and rectangular, and the cross section of the guide part 2 is also rectangular in accordance with the base hole 10. The supporting body 21 at this time includes a supporting frame 211 matched with the base hole 10, the supporting frame 211 has a plurality of guide bars 212 therein, the guide holes 210 are opened on end surfaces of the guide bars 212, and each guide bar 212 is slidably connected with the supporting frame 211 through an adjusting portion. The adjusting part comprises a sliding block 213 fixed on the guide bar 212, a threaded locking hole 2130 is arranged on the sliding block 213 along the length direction of the base hole 10, a sliding track 214 is arranged on the supporting frame 211, the sliding track 214 is arranged along the direction perpendicular to the length direction of the base hole 10, and the sliding block 213 is inserted into the sliding track 214 to match with the sliding track 214.
The adjusting part also comprises an adjusting hole 215 which is arranged on the end surface of the supporting frame 211 along the length direction of the base hole 10, the adjusting hole 215 passes through the sliding track 214, and the cross section length of the adjusting hole is enough for the sliding block 213 to move freely in the sliding track 214; the adjusting hole 215 is inserted with a locking pin 216, the locking pin 216 has a thread matching with the locking hole 2130, and the locking pin 216 can be inserted into the locking hole 2130 to fix the sliding block 213 and the support frame 211.
In the operation of this embodiment, the head of the spatula 1, the camera or the like is not easily inserted through the base hole 10 by the tool of the guide hole 210 according to the actual situation. And then the guide part 2 is inserted into the base hole 10, and the guide strip 212 is ensured to be partially remained outside the base hole 10, when the guide part 2 is inserted, the handle parts of the tools such as the scraper 1, the camera and the like are firstly aligned with the guide hole 210, and the handle parts are ensured to penetrate into the guide hole 210. Finally, the focus 100 is scraped by rotating the scraper 1, the part of the guide strip 212 reserved outside the base hole 10 is moved, the position of the guide hole 210 is adjusted, as shown in fig. 3-6, the guide strip 212 is moved, the sliding block 213 fixed on the guide strip 212 slides on the sliding track 214 to change the position, the guide strip 212 drives tools required by the operations such as the scraper 1, a camera, a washing tube and the like to move in the support frame 211 to change the position, and after the position is determined, the locking pin 216 is inserted into the locking hole 2130 for fixing. When the position of the scraper 1 and the like needs to be adjusted in the operation, the locking pins 216 are loosened to continuously move the corresponding guide strips 212.
The eccentric design of the scraper 1 can ensure the great action range of the scraper 1 by rotating the cutter handle 11, so that the focus 100 in a large range can be completely scraped under the condition that the diameter of the base hole 10 is very small and the minimally invasive concept is met. The camera that cooperation scraper 1 used can transmit focus 100 inside picture to external equipment, and the medical personnel of being convenient for observes focus 100 condition in real time, adjusts and confirms the operation position. The irrigation tube can timely suck out the scraped focus 100, clean the focus 100, enlarge the operable range of the operation and facilitate the camera to obtain a clearer visual field.
In addition, a surgical electrode 122 is fixed to the blade 12 of the shaver 1, and the surgical electrode 122 is connected to the electrosurgical unit through the handle 11. The operation electrode 122 can burn the bone wall around the focus 100 to inactivate the residual cells, thereby ensuring that the focus 100 cells are scraped more thoroughly.
For the drilling of the base hole 10, the steps are as follows: a. drilling a hole in the center of the bone core of the taken focus 100 through a positioning needle for positioning. b. The skin is cut linearly by taking the positioning needle as a center, the skin is driven into a soft tissue separator, surrounding soft tissues are separated until reaching the bone surface, and the tail end of the positioning needle can be seen. c. Screwing the positioning sleeve into the bone along the positioning direction under the guidance of the soft tissue separator, wherein the depth is 100 degrees of contact with the focus; the positioning needle 12 and the soft tissue separator are removed. d. The open-circuit trephine is used for penetrating the positioning sleeve, and the position of the focus 100 is not tightly connected with surrounding bone tissues, so that the cutting device at the far end of the trephine can automatically cut off the connection position of the bone core and the focus 100. e. The bone core is extracted and a basal hole 10 is formed.
The above is only a preferred embodiment of the invention, and any simple modifications, variations and equivalents of the invention may be made by anyone in light of the above teachings and fall within the scope of the invention.
