[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 7 An orthopedic arthroscopic puncture instrument comprises a popliteal pad 1, a binding assembly 2 is arranged on the top of the popliteal pad 1, the binding assembly 2 comprises an arc frame 21 movably mounted on the right side of the top of the popliteal pad 1, the arc frame 21 is inclined to the left in an arc shape, a first binding strap 24 is fixedly mounted on the left side of the top of the arc frame 21, and a binding 11 is fixedly mounted on the left side of the top of the popliteal pad 1;

[0036] The interior of the arc frame 21 is provided with a hand frame auxiliary component 3, and the hand frame auxiliary component 3 includes a mobilization frame 31 movably installed inside the arc frame 21, and a mobilization block 32 is movably installed inside the mobilization frame 31, and a connecting rod 33 is movably installed on the top of the mobilization block 32, and a linkage block 34 is movably installed on the top of multiple connecting rods 33. The centers of the mobilization block 32 and the linkage block 34 are respectively provided with a first through hole 326 and a second through hole 341, and an arthroscopic puncture device body 6 is movably installed between the mobilization block 32 and the linkage block 34 through the first through hole 326 and the second through hole 341. The inner walls of the front and rear ends of the arc frame 21 are both provided with a first sliding Slot 22, a limiting tooth 23 is fixedly installed inside the first slide groove 22, a first sliding block 311 is fixedly installed at both the front and rear ends of the adjustment frame 31, a first positioning tooth 312 is movably installed on the surface of the first sliding block 311 close to the first slide groove 22, and a second slide groove 316 is opened on the left and right sides of the inner wall of the adjustment frame 31, and a second sliding block 321 is fixedly installed on the left and right sides of the adjustment block 32, the overall curvature of the first sliding block 311 is consistent with the first slide groove 22, and can slide in the first slide groove 22, and the adjustment block 32 is movably installed inside the adjustment frame 31 through the second sliding block 321 and the second slide groove 316.

[0037] By adopting the above technical solution, when in use, the popliteal pad 1 is placed in the popliteal fossa below the patient's knee, and then the arc frame 21 is rotated to cover the side of the patient's knee. At this time, the first strap 24 is passed through the strap 11 to fix the arc frame 21. The first strap 24 is used in the same way as Velcro. After fixing the arc frame 21, first adjust the hand frame auxiliary component 3 to align the first through hole 326 with the knee opening position, and finally insert the arthroscopic puncture device body 6 into the hand frame auxiliary component 3. After the arthroscopic puncture device body 6 is inserted, the arthroscopic puncture tube body is located in the first through hole 326, and the arthroscopic handle is located in the second through hole 341. Through the above structural setting, the arthroscopic puncture device body 6 does not need to be held by medical staff for a long time when in use, thereby avoiding hand fatigue of medical staff and reducing the quality of the monitoring picture in the patient's knee. At the same time, it also avoids the problem of arthroscopic puncture device body 6 being damaged. The problem of shaking hurting the patient's knee occurs. The adjustment frame 31 is installed on the arc frame 21 through the first sliding block 311 and the first sliding groove 22 at the front and rear ends, and can slide up and down. When sliding, the first touch block 313 needs to be pinched. The first touch block 313 drives the first positioning tooth 312 to move through the first linkage plate 314, and at the same time compresses the first spring 315. At this time, the first positioning tooth 312 is no longer engaged with the limiting tooth 23 in the first sliding groove 22, and the adjustment frame 31 can be slid. After sliding is completed, the first touch block 313 is released, the pressure of the first spring 315 is released, and the first positioning tooth 312 is engaged with the limiting tooth 23 again to complete the locking of the adjustment frame 31. This structural setting is convenient for the adjustment frame 31 to move. When the adjustment frame 31 moves and adjusts, it drives the adjustment block 32 and the linkage block 34 to move, thereby adjusting the position of the arthroscopic puncture instrument body 6, and locking it after adjustment, without the need to hold the arthroscopic puncture instrument body 6 by hand.

[0038] like Figures 1 to 8As shown, the front and rear ends of the adjustment frame 31 are located above the first sliding block 311 and are movably installed with a first touch block 313. The first touch block 313 and the first positioning tooth 312 on the side away from the first slide slot 22 extend into the adjustment frame 31, and a first linkage plate 314 is fixedly connected between the first touch block 313 and the first positioning tooth 312. A first spring 315 is fixedly installed on the side of the first linkage plate 314 away from the first touch block 313 and the first positioning tooth 312. A second touch block 323 is movably installed on the right side above the second sliding block 321, and a second positioning tooth 322 is movably installed on the surface of the second sliding block 321 away from the adjustment block 32. The second positioning tooth 322 and the second touch block 323 extend into the adjustment block 32 on the side close to the adjustment block 32, and a second linkage plate 324 is fixedly connected between the second positioning tooth 322 and the second touch block 323, and a second spring 325 is fixedly installed on the side of the second linkage plate 324 close to the first through hole 326.

[0039] By adopting the above technical solution, the inner wall of the adjustment frame 31 is further provided with a second slide groove 316, and at the same time, a tooth engaged with the second positioning tooth 322 is provided in the second slide groove 316. The adjustment block 32 can be adjusted in the same manner as the adjustment frame 31 through the arrangement of the second touch block 323, the second sliding block 321, the second positioning tooth 322 and other structures. When the adjustment block 32 is adjusted, it moves through the second slide groove 316 and the second sliding block 321 inside the hand frame auxiliary component 3, pinches the second touch block 323, and the second touch block 322 is adjusted. The block 323 drives the second linkage plate 324, and the second linkage plate 324 drives the second positioning tooth 322. At the same time, the second linkage plate 324 compresses the second spring 325. At this time, the second positioning tooth 322 retracts into the second sliding block 321 and is no longer engaged with the tooth provided in the second sliding groove 316. At this time, the adjustment block 32 can be moved. The adjustment block 32 can move forward and backward in the adjustment frame 31. After adjustment, the second contact block 323 is released, and the pressure of the second spring 325 is released through the second linkage plate 324 to make the second positioning tooth 322 2 reset, and engage with the teeth in the second slide groove 316 again to complete the positioning. The mobilizing block 32 drives the linkage block 34 on the top to move while moving. The linkage block 34 is installed on the top of the mobilizing block 32 through the connecting rod 33. Threads 331 are provided at both ends of the connecting rod 33, and the top of the mobilizing block 32 and the bottom of the linkage block 34 are provided with thread grooves 332 that match the connecting rod 33. The connecting rod 33 is installed by rotating with the help of the thread 331. The linkage block 34 is detachable through the connecting rod 33. The linkage block 34 can be installed or not according to actual use requirements. Through the above-mentioned structural design, the mobilizing frame 31 can be adjusted and moved up and down along the arc frame 21, and the mobilizing block 32 can be moved left and right along the mobilizing frame 31, so that the device is easy to adjust in position, and there will be no problem of affecting the normal operation of the arthroscopic puncture device body 6, thereby ensuring that the arthroscopic puncture device body 6 can still maintain a certain flexibility during work, and automatically lock the position after adjustment to ensure its auxiliary support ability for the arthroscopic puncture device body 6.

[0040] like Figures 5 to 8As shown, threads 331 are provided at the upper and lower ends of the connecting rod 33, and thread grooves 332 that match the two ends of the connecting rod 33 are provided at the top of the adjusting block 32 and the bottom of the linkage block 34. The inner walls of the adjusting block 32 and the linkage block 34 are provided with a puncture tube limiter 4, and the puncture tube limiter 4 includes a first receiving groove 41 provided on the inner wall of the adjusting block 32, and a seesaw 42 is movably installed inside the first receiving groove 41, and a third spring 43 is fixedly installed on the side wall of the seesaw 42 away from the first through hole 326. A mounting groove 44 is provided at the bottom of the adjusting block 32, and a liquid blocking ring 45 is movably installed at the bottom of the mounting groove 44, and a mounting head 46 is fixedly installed on the top of the liquid blocking ring 45, and the mounting head 46 is movably installed inside the mounting groove 44, and the interior of the liquid blocking ring 45 is filled with filling cotton 48, and a third through hole 47 communicating with the first through hole 326 is provided at the center of the liquid blocking ring 45.

[0041] By adopting the above technical solution, a first receiving groove 41 is opened inside the maneuvering block 32, and a seesaw 42 is installed inside the first receiving groove 41, and a third spring 43 is installed on the side of the seesaw 42 away from the first through hole 326, so that the seesaw 42 is in a state of tilting toward the center of the first through hole 326, and a puncture tube limiter 4 is also installed in the second through hole 341. When the arthroscopic puncture device body 6 is inserted into the first through hole 326, the puncture tube body of the arthroscopic puncture device body 6 is located in the first through hole 326. At this time, the first through hole 326 is in a state of tilting due to the insertion of the puncture tube body into the seesaw 42. Due to its extrusion, it will be compressed, and the seesaw 42 will be clamped on the surface of the puncture tube body through the action of the third spring 43. When the diameter of the puncture tube body inserted into the first through hole 326 is slightly smaller, the seesaw 42 can also keep it in the center position, which can better limit the arthroscopic puncture device body 6 and improve the application range of the device to the arthroscopic puncture device body 6. As long as the puncture tube body diameter of the arthroscopic puncture device body 6 is smaller than the diameter of the first through hole 326 and larger than the minimum clamping range of the seesaw 42, it can be used. The second through hole 341 set in the linkage block 34 plays a role in the opponent The handle has a clamping function. The bottom of the maneuvering block 32 is also equipped with a liquid blocking ring 45 through a mounting groove 44 and a mounting head 46. A third through hole 47 is provided at the center of the liquid blocking ring 45. The third through hole 47 is connected to and perpendicular to the first through hole 326, and does not affect the normal operation of the arthroscopic puncture device body 6. When the device is in use, the liquid blocking ring 45 is in a state of fitting with the patient's knee and covering the puncture site. The liquid blocking ring 45 is filled with filling cotton 48. During the puncture hand-held process, most of the patient's knees have effusion, so the effusion in the patient's knee may pass through the puncture. The fluid flows out of the puncture hole, and the liquid-blocking ring 45 covers the periphery of the puncture hole, and the flowing effusion can be absorbed by the filling cotton 48, so that the medical staff does not need to constantly wipe the effusion flowing out of the patient's knee puncture hole during the operation. Through the arrangement of the above-mentioned components, the application scope of the device is improved, and it can be better matched with the arthroscopic puncture device body 6 to cooperate in completing the operation. At the same time, through the arrangement of the liquid-blocking ring 45, the effusion flowing out of the patient's knee can also be actively absorbed, and the medical staff does not need to constantly wipe the flowing effusion during the operation, thereby improving the functionality of the device itself and making it better to use.

[0042] like Figures 1 to 9As shown, the front and rear ends of the popliteal pad 1 are provided with a support assembly 5, and the support assembly 5 includes a first support plate 51 and a second support plate 54 movably mounted at the front and rear ends of the popliteal pad 1, a through hole 52 is opened on the top right side of the first support plate 51, and a second strap 53 is fixedly installed on the top left side of the first support plate 51, the second support plate 54 has the same structure as the first support plate 51, and both are movably mounted with the popliteal pad 1 through bearings, a positioning rod 55 is movably mounted on the right side of the first support plate 51, and a positioning hole 551 is opened on the rear end surface of the positioning rod 55, and the second support plate 5 4 is provided with a second receiving groove 541 inside the right rear end, a pull rod 542 is movably installed inside the second receiving groove 541, a positioning block 543 is fixedly installed on the right side of the pull rod 542, a pull ring 544 is fixedly installed on the right side of the positioning block 543, the surface of the pull rod 542 is located inside the second receiving groove 541 and a fourth spring 545 is sleeved thereon, the positioning block 543 can be inserted into the positioning hole 551, the area of ​​the pull ring 544 is larger than the area of ​​the positioning hole 551, and the length of the positioning rod 55 is the same as the sum of the lengths of the first support plate 51, the second support plate 54 and the popliteal fossa pad 1.

[0043] By adopting the above technical solution, the front and rear ends of the popliteal fossa pad 1 are respectively installed with the first support plate 51 and the second support plate 54 through bearings. When the popliteal fossa pad 1 is placed on the patient's popliteal fossa, the pull ring 544 is first pulled, and the pull ring 544 drives the positioning block 543 and the pull rod 542 to move. At this time, the positioning block 543 extends out from the positioning hole 551 and compresses the fourth spring 545. At this time, the restriction of the positioning rod 55 on the first support plate 51 and the second support plate 54 can be released, and the first support plate 51 and the second support plate 54 can be rotated to make the first support plate 51 and the second support plate 54 fit the patient's thigh and calf abdomen. At this time, the pull ring 544 is released again to release the pressure of the fourth spring 545. The fourth spring 545 drives the positioning block 543 to retract and reinsert it into the positioning hole 551. At this time, the pull ring 544 can be rotated to make the positioning block 543 match the shape of the positioning hole 551 to ensure that the positioning block 543 is inserted into the positioning hole The first support plate 51 and the second support plate 54 are fixed to the hole 551, thereby completing the positioning of the first support plate 51 and the second support plate 54. At this time, the first support plate 51 and the second support plate 54 can be bound to the patient's thigh and calf through the second strap 53 and the perforation 52 to complete the fixation of the device to the patient's limbs. The device can be better fixed to the patient through the above-mentioned structural design. At the same time, the adjustable design of the first support plate 51 and the second support plate 54 allows the patient to use it when lying flat with the legs straight or bent, further improving the applicability of the device and making it usable in most situations. At the same time, the first support plate 51 and the second support plate 54 can be positioned after adjustment, and the patient's limbs can be fixed by the second strap 53. When the patient's limbs are in a bent state, the above-mentioned structure can play a role in auxiliary support of the patient's limbs and fix them, further improving the functionality of the device itself.

[0044] Instructions for use: When in use, first pull the pull ring 544 to separate the positioning block 543 from the positioning hole 551, so that the first support plate 51 and the second support plate 54 can rotate, and then place the popliteal pad 1 on the patient's popliteal fossa, and fix the first support plate 51 and the second support plate 54 through the cooperation of the second strap 53 and the perforation 52, and then cover the arc frame 21 on the patient's knee, and fix the arc frame 21 through the first strap 24 and the strap 11. At this time, the position of the hand frame auxiliary component 3 can be adjusted to align the first through hole 326 with the puncture part. When adjusting, pinch the first touch block 313 to retract the first positioning tooth 312. At this time, the frame 31 can be slid up and down to adjust. After adjustment, release the first touch block 313, and the adjustment frame 31 automatically adjusts to The arc frame 21 is fixed. When adjusting the position of the adjustment block 32, the second touch block 323 needs to be pinched to retract the second positioning tooth 322.
