Description

Technical Field

[0001] The utility model relates to the field of medical instruments, and in particular to an implant device. Background Art

[0002] The implant handle of the external row anchor used is a disposable sterile product made of polymer material, which cannot be sterilized at high temperature or reused. In order to reduce the cost of use, veterinary medicine hopes that the implant handle of the external row nail is a reusable and sterilizable product.

[0003] The nails currently used in the market are made of polymer materials and do not show up under CT or X-ray machines. Since animals cannot express their feelings after implantation in words, doctors usually need to use CT, X-ray and other imaging methods to determine the state of the anchor in the animal after surgery, which requires the implanted anchor to be made of metal.

[0004] The existing product structure is based on the product being a polymer material, a one-time sterilized product, which does not meet the requirements of veterinary medicine. To solve these two problems, it is necessary to develop an external row anchor with a reusable handle, multiple sterilizations, and suitable for animal use. Utility Model Content

[0055] Embodiment 1

[0056] Please refer to Figure 1 and Figure 8 This embodiment provides an implant device 010, which is mainly used in animal medical surgery.

[0057] Please refer to Figure 1-Figure 3 The implant device 010 proposed in this embodiment includes a driving rod 120 and an anchor head 110; a driving head 122 is provided at the distal end of the driving rod 120; the proximal end of the anchor head 110 is a mating end, and a driving part 111 is provided on the mating end of the anchor head 110, and the driving part 111 is detachably connected to the driving head 122.

[0058] The proximal end of the implant device 010 is the end close to the operator, and the distal end is the end close to the anchor head 110 .

[0059] It is understandable that the metal anchor head 110 and the driving rod 120 can be sterilized at high temperatures for many times and reused, and have a long service life. However, when the anchor head 110 is made of metal, it is impossible to process a thread with a particularly small pitch on the anchor head 110 or the processed thread has a very short service life; therefore, the driving part 111 of the anchor head 110 is detachably connected to one end of the driving rod 120 through an interference fit, which reduces the manufacturing difficulty of the anchor head 110 and makes the installation of the anchor head 110 and the driving rod 120 more convenient; at the same time, after the anchor head 110 is implanted in the bone, the driving rod 120 can be reused, reducing the cost of use.

[0060] Please refer to Figure 2 and Figure 6 In this embodiment, the implant device 010 includes an anchor head 110 .

[0061] Specifically, the proximal end of the anchor head 110 is the mating end, and a driving part 111 is provided on the anchor head 110.

The clamping portion 121 is provided with a tapered mating surface 1211. The tapered mating surface 1211 cooperates with the inner wall of the implant anchor 130 to prevent the implant anchor 130 from slipping during the implantation process. Please refer to Figure 3-Figure 6 A driving head 122 with a spherical structure is provided at both ends of the driving rod 120, which can increase the number of times the product can be reused.

[0066] The driving head 122 with a spherical end is disposed in the driving portion 111 , and a gap exists between the driving head 122 and the driving portion 111 .

[0067] Of course, in other embodiments, the driving rod 120 may also be provided with a driving head 122 only at the proximal end.

[0068] The driving rod 120 is made of metal, such as titanium alloy or stainless steel.

[0069] It is worth mentioning that please refer to Figure 2 and Figure 6 In this embodiment, the driving portion 111 is a driving hole, and the structure of the driving hole is a connected columnar through hole and a circular hole, and both ends of the connected columnar through hole and circular hole transversely penetrate both sides of the anchor head 110. Correspondingly, the end of the driving head 122 is also a spherical structure.

[0070] Please refer to Figure 9-10 In other embodiments, the driving portion 111 is also a driving hole, and the structure of the driving hole is a circular hole and a columnar through hole set at the upper and lower ends of the circular hole, and both ends of the columnar through hole set at the lower end and the circular hole both transversely penetrate the two sides of the anchor head 110. Correspondingly, the end of the driving head 122 is a columnar structure with a ball, and the ball cooperates with the circular hole. Of course, when the driving portion 111 is a driving hole, the structure of the driving hole can be other forms of hole structures.

[0071] Please refer to Figure 1 as well as Figure 8 In this embodiment, the implant device 010 includes an implant anchor 130 .

The driving rod 120 is fixed to the connecting rod 160 by the magnet 150 , which is convenient for disassembly and assembly.

[0077] The magnet 150 and the connecting rod 160 are both cylindrical structures with the same diameter.

[0078] Please refer to Figure 1 and 7 In this embodiment, the implant device 010 includes a sleeve 140. One end of the inner wall of the sleeve 140 is used to sleeve the cylindrical surface of the magnet 150 and the connecting rod 160; the other end of the inner wall of the sleeve 140 is a matching surface for matching with the driving head 122 and the driving rod 120.

[0079] The driving rod 120 is arranged in the sleeve 140 in cooperation with the magnet 150 , and driving rods 120 of different lengths can be used in cooperation with the magnet 150 .

[0080] Please refer to Figure 7 In this embodiment, the implant device 010 includes a threaded rod 170 , one end of the threaded rod 170 is fixed to the connecting rod 160 , and the other end of the threaded rod 170 is fixed to the implant handle 180 .

[0081] Please refer to Figure 1 In this embodiment, the implantation device 010 includes an implantation handle 180 , and the implantation handle 180 is fixed to the threaded rod 170 .

[0082] Please refer to Figure 1 and Figure 7 In this embodiment, the implant device 010 includes a connected gripping handle 190 and a sleeve 200 .

[0083] Specifically, the gripping handle 190 is sleeved on the connecting rod 160, and the gripping handle 190 is provided with a connecting through hole with an internal thread at one end; the gripping handle 190 is threadedly connected to the threaded rod 170 through the internal thread; and a sleeve 200 is fixed to the other end of the gripping handle 190. The sleeve 200 is sleeved on the connected connecting rod 160 and the driving rod 120, one end of the sleeve 200 is connected to the gripping handle 190, and the other end is matched with an extension tube 210, and is used to match and abut against the implanted anchor 130.

[0084] It is understandable that the doctor holds the implantation handle 180 to make the anchor head 110 contact the bone surface, and at the same time rotates the gripping handle 190 to screw the implantation anchor 130 into the bone. During the screwing-in process of the implantation anchor 130, it can play a guiding and supporting role in the axial direction, and can prevent the implantation anchor 130 from axial deviation during the screwing-in process, thereby improving the implantation efficiency of the implantation anchor 130, and further facilitating the smooth progress of the operation.

[0085] The gripping handle 190 is a flat and long structure, which conforms to the shape of a human body grip, so that the user has a better grip feeling.

[0086] In this embodiment, the implantation device 010 includes an extension tube 210 . The extension tube 210 is sleeved on the driving rod 120 ; one end of the extension tube 210 is connected to the sleeve 200 , and the other end is used to cooperate with and abut one end of the implantation anchor 130 .

[0087] It is understandable that the extension tube 210 allows the implant device 010 to be used in conjunction with implant anchors 130 of different lengths; by adding the extension tube 210, short anchors and long anchors can share the implant device 010, which is economical and practical.

[0088] Of course, please refer to Figure 3 In other embodiments, the gripping handle 190, the tube sleeve and the extension tube 210 may not be provided, depending on the actual surgical situation.

[0089] The use process of the implant device 010 of this embodiment is as follows:

[0090] First, after the suture is inserted into the threading hole 112 of the anchor head 110 , the implant anchor 130 is inserted into the driving rod 120 from the anchor head 110 and abuts against the extension tube 210 .

[0091] Then, the operator holds the implantation handle 180 and implants the anchor head 110 into the port of the bone tunnel. The operator rotates the gripping handle 190 relative to the threaded rod 170 to move the gripping handle 190 toward the anchor head 110; the gripping handle 190 moves while driving the sleeve 200, the extension tube 210 and the implantation anchor 130 to move together until the implantation anchor 130 abuts against the mating end of the anchor head 110.

[0092] Finally, the operator continuously rotates the gripping handle 190, the implantation anchor 130 abuts against the anchor head 110 and cancels the matching between the driving hole of the anchor head 110 and the driving head 122 of the driving rod 120; the implantation anchor 130 pushes the anchor head 110 into the bone canal until the implantation anchor 130 is screwed into the bone canal and fixed in the bone canal and the suture is compressed and fixed with the anchor head 110, thereby completing the implantation of the anchor head 110 and the implantation anchor 130.

[0093] Embodiment 2

[0094] Compared with the first embodiment, the connection method between the driving rod 120 and the anchor head 110 in this embodiment is different, and the other components and usage methods are the same.

[0096] In this embodiment, the protrusion structure is a rhombus-shaped protrusion, and the groove is a cylindrical groove. Of course, in other embodiments, the protrusion structure can also be a cylindrical protrusion or the like.

[0097] In summary, the implantation device 010 of this embodiment, its metal anchor head 110 and driving rod 120 can be sterilized and reused for many times at high temperatures, and have a long service life; at the same time, the driving part 111 of the anchor head 110 is detachably connected to one end of the driving rod 120, which reduces the manufacturing difficulty of the anchor head 110 and makes the installation of the anchor head 110 and the driving rod 120 more convenient; at the same time, after the anchor head 110 is implanted in the bone, the driving rod 120 can be reused, reducing the cost of use.

[0098] Furthermore, by providing the extension tube 210, the implantation device 010 can be used in conjunction with implantation anchors 130 of different lengths, so that short anchors and long anchors can share the implantation device 010, which is economical and practical.
