Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a transforaminal vertebral body shaping kit. Background Technology

[0002] Percutaneous vertebroplasty, as an important technique in minimally invasive spinal surgery, has become the mainstream treatment for osteoporotic vertebral compression fractures. Clinically, most procedures establish a working channel through a transpedicular approach, injecting bone cement into the affected vertebral body to achieve vertebral reinforcement. Its advantages include significantly shortening the operation time, and patients can generally resume walking within 43 hours post-surgery. However, existing transpedicular vertebroplasty kits have some drawbacks. The surgery requires high precision in positioning, and the puncture path is relatively long. Excessive abduction can easily puncture the pedicle and enter the spinal canal, causing bone cement leakage and potentially leading to serious complications such as nerve damage. Insufficient abduction during transpedicular puncture makes it difficult to reach the ideal center of the vertebral body, often requiring bilateral punctures, which doubles the trauma and carries the risk of pedicle fracture.

[0003] Transforaminal puncture is a more ideal puncture route, but there are no dedicated transforaminal puncture kits available on the market. Currently, conventional transpedicle puncture kits are used instead, which may have some impact on the safety of the surgery. On the other hand, there is bleeding from the wound or the open cannula during the operation. During the removal of the cannula after the procedure, blood often seeps out along the wound. It is necessary to use highly absorbent hemostatic gauze or a suction tube connected to a negative pressure suction device to continuously clean up the seeping blood. At the same time, after the puncture cannula is removed, medical staff often need to place hemostatic gauze on the wound and continuously press the hemostatic gauze for 10-30 minutes to wait for the blood to clot and stop the bleeding. Prolonged pressing can cause fatigue and soreness in the hands of medical staff, increasing their workload and labor burden. Utility Model Content

[0039] (III) Beneficial Effects

[0040] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0041] I. This utility model solves the current clinical problem of the lack of a dedicated puncture kit for transforaminal vertebroplasty, filling an application gap;

[0042] The anchoring guide pin can guide the puncture path of the puncture rod, improving surgical safety and efficiency.

[0043] Second, in this utility model, through the set drainage cavity, when the injection cannula or external puncture tube is pulled out, the blood flowing out of the wound will be drawn into the drainage cavity through the suction port by the action of the external suction pump, and discharged to the designated location by the external suction pump, without the need for additional medical staff to use hemostatic cotton to continuously clean the extravasated blood.

[0044] Third, in this utility model, the pressure cap is reinstalled on the inner retaining ring by the cooperation of the external thread screwing part and the internal thread screwing part. At the same time, the rotating rod continues to rotate, causing the pressure cap to rotate. Under the meshing action of the external thread screwing part and the internal thread screwing part, the pressure cap will drive the sterile gauze at its bottom to move downward, so that the sterile gauze can press on the wound and stop bleeding, without the need for manual long-term pressing.

[0045] Fourth, in this utility model, the skin patch and the outer edge patch and the rubber pressure sleeve can be detachably fixed together by the set skin patch, and the skin patch and the blood-blocking ring can be attached to the patient's skin by the adhesive layer, thereby fixing the blood-blocking ring at the designated position.

[0046] V. In this utility model, after the wound hemostasis is completed, the staff can remove the rubber sleeve from the inner groove through the clearance groove. At this time, the squeezing force of the rubber sleeve on the outer edge patch disappears, so that the staff can remove the hemostatic ring.

[0047] VI. In this utility model, the rubber sleeve can increase the friction between the insert ring and the inner edge, preventing the inner locking ring and the blood-blocking ring from falling off during use or transportation. The blood-blocking ring and the inner locking ring can be quickly integrated together during production, reducing the difficulty of injection molding for one-piece molding.

[0068] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0069] Example 1

[0070] like Figures 1-19 As shown, a transforaminal vertebral body shaping kit includes an anchoring guide needle 1, an injection cannula 2, an external puncture kit 3, an internal puncture kit 4, a reaming kit 5, a support kit 7, a mud cannula 8, and a push rod 9.

[0071] The anchoring guide needle 1 is detachably inserted into the injection cannula 2. Specifically, the bottom of the anchoring guide needle 1 is provided with a spiral self-tapping tip so that the anchoring guide needle 1 can puncture through the intervertebral foramen to reach the vertebral body surface and anchor in the vertebral bone.

[0072] The top of the anchoring guide pin 1 is threaded with a rotating nut 11. When anchoring, the operator can install the rotating nut 11 on the top of the anchoring guide pin 1 and rotate the rotating nut 11 to drive the anchoring guide pin 1 to rotate, so that the self-tapping tip is anchored in the vertebral bone.

[0073] The bottom of the injection cannula 2 is obliquely pointed to facilitate puncture and injection of local anesthetic drugs;

[0074] Specifically, during the surgery, the injection cannula 2 is first connected to an external syringe containing anesthetic drugs to administer local anesthesia to the patient. Then, the external syringe is removed, and the rotating nut 11 is installed on the top of the anchoring guide needle 1. The anchoring guide needle 1 is then inserted into the injection cannula 2 and, under the monitoring of an X-ray fluoroscopy machine, reaches the target vertebral body surface through the intervertebral foramen. The anchoring guide needle 1 is then rotated by rotating the rotating nut 11, thereby anchoring the self-tapping tip into the vertebral bone.

[0075] After anchoring is complete, remove the rotating nut 11 from the top of the anchoring guide pin 1, and then remove the injection sleeve 2.

[0076] Both the internal puncture kit 4 and the mud cannula 8 can be detachably inserted into the external puncture kit 3;

[0077] The push rod 9 is detachably inserted into the mud sleeve 8. Specifically, the external puncture kit 3 includes a first pinch plate 31 and an external puncture tube 32 fixedly inserted at the bottom of the first pinch plate 31. The top opening of the external puncture tube 32 penetrates the first pinch plate 31.

[0078] The internal puncture kit 4 includes a second pinch plate 41 and a puncture rod 42 fixed to the second pinch plate 41. The bottom of the puncture rod 42 is provided with a reaming head 43, and a guide needle slot 4202 is provided on the puncture rod 42. The bottom of the guide needle slot 4202 passes through the reaming head 43, and the top of the guide needle slot 4202 passes through the second pinch plate 41.

[0079] The bottom of the second pinch plate 41 is provided with a snap-fit ​​groove 4201 that is compatible with the first pinch plate 31. The piercing rod 42 is inserted into the outer piercing tube 32, and the first pinch plate 31 is snapped into the snap-fit ​​groove 4201.

[0080] Anchor pin 1 is inserted into pin slot 4202.

[0081] Specifically, after the injection cannula 2 is removed, the external puncture tube 32 is fitted onto the puncture rod 42, and the first pinch plate 31 is engaged in the engagement groove 4201. After the fitting is completed, the reaming head 43 extends out of the external puncture tube 32. During reaming, the top of the anchoring guide needle 1 is aligned with the guide needle slot 4202. At this time, the puncture rod 42 and the reaming head 43 at its bottom will move along the path of the anchoring guide needle 1. Then, under the action of the reaming head 43, the puncture rod 42 drives the external puncture tube 32 to puncture along the anchoring guide needle 1. During the procedure, the staff rotates the second pinch plate 41 to drive the puncture rod 42 and the reaming head 43 to rotate. Under the monitoring of the X-ray fluoroscopy machine, the puncture tube 32 is drilled into the designated position of the target vertebra through the intervertebral foramen. During the rotation, the second pinch plate 41 drives the first pinch plate 31 to rotate together through the locking groove 4201, so that the external puncture tube 32 and the reaming head 43 are drilled into the designated position of the target vertebra. The anchoring guide needle 1 can guide the puncture path of the puncture rod 42, improving the safety and efficiency of the operation.

[0082] After drilling is completed, the anchoring guide needle 1 and the internal puncture kit 4 are removed from the external puncture kit 3 for hole enlargement. The enlargement kit 5 includes a third pinch plate 51 for easy handling by the operator and an enlargement drill bit 52 fixedly inserted at the bottom of the third pinch plate 51. The enlargement drill bit 52 slides in contact with the inner wall of the external puncture tube 32. The enlargement drill bit 52 is inserted into the external puncture tube 32 and drilled under the monitoring of an X-ray fluoroscopy machine to allow the enlargement drill bit 52 to enter the osteoporosis area. Then the enlargement drill bit 52 is removed from the external puncture tube 32 for further hole enlargement.

[0083] The expansion kit 7 includes a fourth pinch plate 71 and a trachea 72 fixedly inserted at the bottom of the fourth pinch plate 71. The outer wall of the trachea 72 slides in contact with the inner wall of the external puncture tube 32, and an air bag 73 is fixedly fitted at the bottom of the trachea 72. The air inlet of the trachea 72 extends out of the top of the fourth pinch plate 71 and is connected to an external air pump. The air outlet of the trachea 72 is connected to the inner cavity of the air bag 73. The air bag 73 is filled with contrast agent so that the staff can observe the expansion size of the air bag 73 through an X-ray fluoroscopy machine. The trachea 72 is inserted into the external puncture tube 32, and the external air pump injects gas into the inner cavity of the air bag 73 through the trachea 72 to inflate it, thereby compressing the bone in the osteoporotic area. At the same time, it can also further expand the hole that has just been drilled.

[0084] The mud sleeve 8 includes a fifth pinch plate 81 and an inner sleeve 82 fixedly inserted at the bottom of the fifth pinch plate 81. The outer wall of the inner sleeve 82 slides in contact with the inner wall of the outer puncture tube 32, and the top opening of the inner sleeve 82 extends through the fifth pinch plate 81.

[0085] The push rod 9 includes a sixth pinch plate 91 and a push rod 92 fixedly inserted at the bottom of the sixth pinch plate 91. The outer wall of the push rod 92 slides in contact with the inner wall of the inner sleeve 82. After the hole is enlarged, the gas in the airbag 73 is discharged by an external air pump, and the air tube 72 is removed from the external puncture tube 32. Then, bone cement is injected into the inner sleeve 82, and the inner sleeve 82 is inserted into the external puncture tube 32 so that the opening of the inner sleeve 82 extends into the osteoporotic area after the hole is enlarged. Next, the push rod 92 is inserted into the inner sleeve 82. By pushing the push rod 92, the bone cement in the inner sleeve 82 is injected into the osteoporotic area after the hole is enlarged, and the osteoporotic area is supported and fixed by the bone cement. The principle of bone cement is existing technology and will not be described in detail here.

[0086] Example 2

[0087] like Figures 1-19 As shown, this embodiment has been improved based on embodiment one as follows: the transforaminal vertebral body shaping kit also includes a blood dam absorption kit 6, which includes a blood-blocking ring 61, an inner locking ring 62, and a skin patch 63 disposed at the bottom of the blood-blocking ring 61.

[0088] The inner locking ring 62 is locked onto the blood-blocking ring 61, specifically as follows: Figures 14-16As shown, the two inner walls of the flow guiding cavity 6101 are provided with inner edges 611. The bottom of the inner locking ring 62 is integrally provided with a plug ring 641 that matches the inner edge 611. A rubber sleeve 622 is provided on the side of the two plug rings 641 that are far apart. The inner locking ring 62 is inserted into the inner edge 611 through the plug ring 641, and the rubber sleeve 622 abuts against the corresponding inner edge 611. The rubber sleeve 622 can increase the friction between the plug ring 641 and the inner edge 611, and prevent the inner locking ring 62 and the blood blocking ring 61 from falling off during use or transportation. The blood blocking ring 61 and the inner locking ring 62 can be quickly integrated together during production, which reduces the difficulty of injection molding. The bottom of the inner locking ring 62 is connected to the flow guiding cavity 6101, thereby sealing the top of the flow guiding cavity 6101.

[0089] A rubber sleeve 64 is detachably engaged between the inner locking ring 62 and the blood-blocking ring 61. The free end of the skin patch 63 is clamped between the rubber sleeve 64 and the blood-blocking ring 61, specifically as follows: Figure 13 As shown, the outer wall of the skin patch 63 is integrally provided with at least two outer edge patches 631. The bottom of both the skin patch 63 and the outer edge patches 631 are coated with an adhesive layer 67, and the surface of the adhesive layer 67 on the skin patch 63 is covered with a bottom peel-off sticker 632, while the surface of the adhesive layer 67 on the outer edge patches 631 is covered with a side peel-off sticker 633.

[0090] The inner locking ring 62 and the blood-blocking ring 61 form an inner groove 68. During production and installation, the operator only needs to fold the outer edge patch 631 along the outer wall of the blood barrier absorption kit 6 into the inner groove 68, and then snap the rubber sleeve 64 into the inner groove 68. After snapping, the outer wall of the rubber sleeve 64 abuts against the side peel-off sticker 633, and the outer edge patch 631 abuts against the inner wall of the blood-blocking ring 61, thereby fixing the skin patch 63 and improving production efficiency.

[0091] A pressure cap 65 is detachably installed on the inner ring wall of the inner locking ring 62. The pressure cap 65 is located at the inner ring opening of the blood-blocking ring 61, and a sterile gauze 66 is clamped to the bottom of the pressure cap 65. A plastic sleeve 661 is detachably fitted onto the outer wall of the sterile gauze 66. Specifically: Figure 16 and Figure 17 As shown, the inner wall of the inner snap ring 62 is provided with an internal thread screwing part 6201, the outer wall of the pressure cap 65 is provided with an external thread screwing part 6501 that meshes with the internal thread screwing part 6201, and a rotating rod 651 is fixedly connected to the top of the pressure cap 65.

[0092] Specifically, before the surgery, the staff removes the bottom peel-off sticker 632, thus attaching the adhesive layer 67 at the bottom of the skin patch 63 to the corresponding location where the patient needs to have the surgery. This allows the inner ring of the blood-blocking ring 61 to be fitted around the drilling point. Then, the rod 651 is rotated, which drives the pressure cap 65 to rotate. Under the engagement action, the pressure cap 65 with the external thread screwing part 6501 is removed from the internal thread screwing part 6201, thus temporarily removing the pressure cap 65 with the sterile gauze 66 attached for later use. Then, the surgery begins. The plastic film 661 prevents the sterile gauze 66 from being infected.

[0093] A positioning baffle 33 is detachably fitted onto the outer wall of the external puncture tube 32. A clamping bolt 34 is threadedly connected to the side of the positioning baffle 33. One end of the clamping bolt 34 passes through the positioning baffle 33 and abuts against the outer wall of the external puncture tube 32. During use, the operator can slide the positioning baffle 33 up and down according to the puncture depth to adjust the position of the positioning baffle 33 on the external puncture tube 32. After adjustment, the clamping bolt 34 is rotated to squeeze the end of the external puncture tube 32, thereby fixing the positioning baffle 33 on the external puncture tube 32. During the operation, the diameter of the positioning baffle 33 is larger than the inner diameter of the inner retaining ring 62. When the external puncture tube 32 is inserted to the predetermined depth, the positioning baffle 33 abuts against the top of the inner retaining ring 62, thereby preventing the operator from puncturing downward.

[0094] like Figure 14 As shown, the blood-blocking ring 61 is provided with a flow-guiding cavity 6101, and the inner ring wall of the blood-blocking ring 61 is provided with an inlet 6102 that communicates with the flow-guiding cavity 6101. The outer ring wall of the blood-blocking ring 61 is provided with an exhaust port 6103 that communicates with the flow-guiding cavity 6101. The free end of the exhaust port 6103 is connected to an external suction pump.

[0095] Specifically, after the blood-blocking ring 61 is attached to the skin patch 63, the external suction pump is turned on. When the injection cannula 2 or the external puncture tube 32 is pulled out, blood will flow out from the wound. The blood-blocking ring 61 can block the outflowing blood into the inner ring of the blood-blocking ring 61, preventing the blood from spreading. At the same time, the external suction pump removes the air inside the drainage cavity 6101, creating a negative pressure inside the drainage cavity 6101. At this time, the blood in the inner ring of the blood-blocking ring 61 will flow into the drainage cavity 6101 through the suction port 6102 and be discharged to the designated location by the external suction pump. There is no need for additional medical staff to use hemostatic cotton to continuously clean the extravasated blood.

[0096] After the surgery is completed and the external puncture tube 32 is removed, while the external suction pump is operating, the staff removes the plastic sleeve 661 covering the sterile gauze 66. Then, through the cooperation of the external thread screwing part 6501 and the internal thread screwing part 6201, the pressure cap 65 is reinstalled on the inner retaining ring 62. At the same time, the rotating rod 651 is rotated to make the pressure cap 65 rotate. Under the meshing action of the external thread screwing part 6501 and the internal thread screwing part 6201, the pressure cap 65 will drive the sterile gauze 66 at its bottom to move downward, so that the sterile gauze 66 can press and stop bleeding at the wound without manual pressure. After the sterile gauze 66 is installed, the external suction pump is turned off.

[0097] During preparation, some permeable drugs that promote hemostasis and coagulation can be added to the sterile gauze 66 to accelerate the blood clotting speed at the wound site.

[0098] Furthermore, the blood-blocking ring 61 is provided with a relief groove 6104 that communicates with the inner groove 68, and the rubber pressure sleeve 64 is connected to the relief groove 6104.

[0099] Specifically, after the wound hemostasis is completed, the staff can remove the rubber sleeve 64 from the inner groove 68 through the relief groove 6104. At this time, the squeezing force of the rubber sleeve 64 on the outer edge patch 631 disappears. The staff can then remove the outer edge patch 631 and peel off the side peel-off sticker 633. Then, the outer edge patch 631 is pasted onto the patient's skin through the adhesive layer 67. As the outer edge patch 631 is removed, the skin patch 63 will also separate from the hemostatic ring 61. At this time, the staff can remove the hemostatic ring 61, but the skin patch 63 will not be peeled off immediately to avoid the wound from rupturing during the peeling process.

[0100] During preparation, some permeable anti-inflammatory agents can be added to the skin patch 63 and the outer edge patch 631 to prevent inflammation and ulceration at the wound site.

[0101] In summary, the workflow of this utility model is as follows:

[0102] Before the surgery, the bottom peel-off sticker 632 is removed, and the adhesive layer 67 at the bottom of the skin patch 63 is attached to the corresponding position where the patient needs to have the surgery. This allows the inner ring of the blood-blocking ring 61 to be fitted around the point to be drilled. Then, the rod 651 is rotated, which drives the pressure cap 65 to rotate. Under the engagement action, the pressure cap 65 with the external thread screwing part 6501 is removed from the internal thread screwing part 6201. The pressure cap 65 with the sterile gauze 66 is temporarily removed for later use. Then, the external suction pump is turned on.

[0103] First, connect the injection cannula 2 to an external syringe containing anesthetic drugs to administer local anesthesia to the patient. Then, remove the external syringe and install the rotating nut 11 on the top of the anchoring guide needle 1. Then, insert the anchoring guide needle 1 into the injection cannula 2 and, under the monitoring of an X-ray fluoroscopy machine, reach the target vertebral body surface through the intervertebral foramen. Then, rotate the rotating nut 11 to drive the anchoring guide needle 1 to rotate, thereby anchoring the self-tapping tip in the vertebral bone.

[0104] After anchoring is completed, remove the rotating nut 11 from the top of the anchoring guide pin 1, and then remove the injection sleeve 2;

[0105] After the injection cannula 2 is removed, the external puncture tube 32 is fitted onto the puncture rod 42, and the first pinch plate 31 is engaged in the engagement groove 4201. After the fitting is completed, the reaming head 43 will extend out of the external puncture tube 32. When reaming, the top of the anchoring guide needle 1 is aligned with the guide needle slot 4202. At this time, the puncture rod 42 and the reaming head 43 at its bottom will move along the path of the anchoring guide needle 1. Then, under the action of the reaming head 43, the puncture rod 42 drives the external puncture tube 32 to puncture along the anchoring guide needle 1. During puncture, the operator rotates the second pinch plate 41 to drive the puncture rod 42 and the reaming head 43 to rotate. Under the monitoring of the X-ray fluoroscopy machine, the needle is drilled into the designated position of the target vertebra through the intervertebral foramen. Then, the anchoring guide needle 1 and the internal puncture kit 4 are removed from the external puncture kit 3.

[0106] The reaming drill bit 52 is inserted into the external puncture tube 32, and drilling is performed under the monitoring of an X-ray fluoroscopy machine, allowing the reaming drill bit 52 to enter the osteoporotic area. The reaming drill bit 52 is then removed from the external puncture tube 32 for secondary reaming. An air tube 72 is inserted into the external puncture tube 32, and an external air pump injects gas into the inner cavity of the air bag 73 through the air tube 72, causing it to inflate and compress the bone in the osteoporotic area. Simultaneously, the previously drilled hole can be further enlarged. After reaming is complete, the external air pump... The air pump expels the gas from the airbag 73 and removes the air tube 72 from the external puncture tube 32. Then, bone cement is injected into the inner cannula 82, and the inner cannula 82 is inserted into the external puncture tube 32 so that the opening of the inner cannula 82 extends into the osteoporotic area after the hole is enlarged. Next, the push rod 92 is inserted into the inner cannula 82. By pushing the push rod 92, the bone cement in the inner cannula 82 is injected into the osteoporotic area after the hole is enlarged, and the osteoporotic area is supported and fixed by the bone cement.

[0107] When the injection cannula 2 or the external puncture cannula 32 is pulled out, blood will flow out from the wound. The air inside the drainage cavity 6101 will be removed by the external suction pump, so that the inside of the drainage cavity 6101 will be negatively pressured. At this time, the blood in the inner ring of the blood blocking ring 61 will flow into the drainage cavity 6101 through the suction port 6102 and be discharged to the designated location by the external suction pump.

[0108] Meanwhile, the staff removed the plastic film 661 covering the sterile gauze 66, and then reinstalled the pressure cap 65 on the inner retaining ring 62 through the cooperation of the external thread screwing part 6501 and the internal thread screwing part 6201. At the same time, the rotating rod 651 continued to rotate, causing the pressure cap 65 to rotate. Under the meshing action of the external thread screwing part 6501 and the internal thread screwing part 6201, the pressure cap 65 would drive the sterile gauze 66 at its bottom to move downward, so that the sterile gauze 66 could press on the wound and stop bleeding. After the sterile gauze 66 was installed, the external suction pump was turned off.

[0109] After the wound hemostasis is completed, the staff can remove the rubber sleeve 64 from the inner groove 68 through the relief groove 6104. At this time, the squeezing force of the rubber sleeve 64 on the outer edge patch 631 will disappear. The staff can then remove the outer edge patch 631 and peel off the side peel-off sticker 633. Then, the outer edge patch 631 is pasted on the patient's skin through the adhesive layer 67. As the outer edge patch 631 is removed, the skin patch 63 will also separate from the hemostatic ring 61. At this time, the staff can remove the hemostatic ring 61.
