The lumbar interbody fusion is a common and effective method for treating LDD, and the lumbar interbody fusion device is used as an important component of the lumbar interbody fusion, mainly has the functions of restoring intervertebral space height and physiological curvature, realizing immediate postoperative stability, reducing fracture of pedicle screws, promoting interbody fusion, and reducing the amount of autologous bone to a certain extent, thereby reducing a series of complications caused by fracture.

Since the lumbar interbody fusion, various surgical approaches have been developed in response to the treatment needs for various kinds of degenerative lumbar diseases, and lumbar interbody fusion cages have been developed. With the deepening of the minimally invasive concept, the lumbar interbody fusion is developing towards the minimally invasive, and the minimally invasive lumbar interbody fusion comprises minimally invasive transforaminal approach lumbar interbody fusion, percutaneous endoscopic lumbar interbody fusion, lateral approach lumbar interbody fusion, oblique lateral approach lumbar interbody fusion and the like. Compared with other operation modes, the intervertebral foramen access has the advantages of minimum influence on surrounding tissues of an affected part, short healing time after operation and the like, but the operation visual field is small, the requirement on the instrument control capability of a doctor is extremely high, when an implantation instrument and an intervertebral fusion cage go deep into a human body, the operation can not be directly performed by visual operation only through touch and experience, and after the doctor places the intervertebral fusion cage at a correct position through precise operation, when the existing implantation instrument is separated from the fusion cage, the fusion cage is easily driven to deviate from the correct position, so that the operation time needs to be repositioned to be delayed.

In order to solve the above-mentioned technical problems, the patent document CN106073950A discloses an implanting apparatus for spinal fusion surgery, which utilizes the relative motion between rigid components to reduce the uncertainty of the operation process caused by the unpredictable factors such as elastic fatigue or motion delay of elastic components or flexible components. The stop bolt abuts against the guide profiles of the first clamping piece and the second clamping piece, so that the first clamping groove and the second clamping groove of the jaw part can be smoothly separated from the clamping end of the interbody fusion cage, and the problems that the existing implantation instrument is easy to shake and shift when the fusion cage is released are solved. Further, as disclosed in patent publication No. CN108697513A, an intervertebral cage inserting apparatus is disclosed, which can stably maintain the posture of an intervertebral cage during insertion and finely adjust the posture of the intervertebral cage when the intervertebral cage is rotated. Above-mentioned technical scheme all can realize intervertebral fusion ware's implantation, and fuse ware and implant between the apparatus the separation convenient, but its in-process of implanting, the relative movement between implantation apparatus and the fusion ware is all limited the value in two-dimensional space, can't realize more complicated displacement relation (three-dimensional), and then leads to can't carrying out more delicate implantation operation.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

< first embodiment >

Referring to the drawings, an intervertebral cage applied to an implanting instrument to be held by the implanting instrument to be placed between adjacent two vertebrae has a cage body 201, and the cage body 201 forms an appearance of the intervertebral cage 1 to have a certain thickness for being inserted between the vertebrae, i.e., a thickness similar to that of an undamaged intervertebral disc. The cage body 201 may have various shapes, such as pea type, crescent type, cashew type, etc., and the cage body 201 has two opposite insertion ends and connection ends, and the insertion ends have sharp streamline contour with acute angle, so as to easily peel off or pass through the fibers of the surrounding tissues of the intervertebral disc and effectively reduce the resistance caused by the residual intervertebral disc tissues.

The upper and lower surfaces of the cage body 201 have rugged contact surfaces for the purpose of increasing the friction between the two vertebrae and the cage body to prevent the intervertebral cage from shifting or separating due to external force after operation.

The fusion cage body 201 is provided with a through hole for accommodating bone powder and allowing tissues such as patient's bone cells, nerves and blood vessels to pass through or attach therebetween to increase healing efficiency, wherein when the volume removal ratio of the through hole is too large, the overall strength of the intervertebral fusion cage 2 is affected, and the structural disintegration may be caused in severe cases. When the removal rate is too small, the healing degree of autologous cells of the patient is affected. Thus, the volume removed by the through-hole is about 1/3-2/3 of the volume of the cage body 201.

The overall contour of the fusion cage body 201 is provided with a circumferential chamfer to avoid the sharp outline from accidentally injuring the surrounding tissues such as nerves, blood vessels and the like in the operation area during the implantation operation.

The connecting end is provided with a clamping groove 202 which can enable the clamping seat 1021 of the implantation instrument to extend into, and the inner wall of the clamping groove 202 is provided with a rough layer 3 for increasing the friction force. The connecting end is used for realizing butt joint with an implanting instrument, and controllable detachable connection needs to be formed between the connecting end and the implanting instrument, namely, the relation between the connecting end and the implanting instrument can be adjusted manually, so that the two components are fastened together or separated from each other. In this embodiment, the above technical purpose is achieved by the arrangement of the rough layer 3, when the card holder 1021 (described in the following embodiment) of the implanting apparatus is placed in the card slot 202 of the connecting end, due to the existence of the rough layer 3, the card holder 1021 of the implanting apparatus cannot be easily separated from the card slot 202 of the connecting end, and when a certain degree of external force is applied, the card holder 1021 can be moved out of the card slot 202, so as to separate the two components.

It is anticipated that the number and the arrangement position of the locking screws 501B and the locking screw holes 203B may be adjusted according to the requirements of industrial design, and are not limited to the above-described position setting.

< fourth embodiment >

Referring to the figures: an implanting instrument for holding and implanting an intervertebral cage between two adjacent vertebrae has an implanting rod 101 and an angle adjusting assembly 102.

The implantation rod 101 has a manipulation end and a connection end, the manipulation end is a distal end during implantation operation, and is used outside the body of a patient during implantation so as to perform various manipulations on the implantation instrument. The connecting end is the end that interfaces with the interbody cage to deliver the interbody cage to the target location.

The angle adjusting assembly 102 comprises a clamping seat 1021 and a rolling ball 1022, wherein the clamping seat 1021 is used for being in butt joint with the intervertebral fusion cage and is provided with a limiting groove 1023 for the rolling ball 1022 to be embedded, the rolling ball 1022 can rotate in the limiting groove 1023 and cannot be separated from the limiting groove 1023, and the rolling ball 1022 is provided with a through hole 1024 formed along an axis. The shape of the limiting groove 1023 is the shape formed by the intersection part of the ball 1022 exceeding 1/2 and the clamping seat 1021. It should be noted that, in order to adjust the angle of the angle adjustment assembly 102 more, the opening of the limiting groove 1023 should be as large as possible, while the ball 1022 is prevented from falling out of the limiting groove 1023.

The implantation rod 101 comprises an outer rod 1011 and a core rod 1012 penetrating the inner part of the outer rod 1011, the core rod 1012 can move along the axial direction of the outer rod 1011, and the outer rod 1011 is arranged in a through hole 1024 of a rolling ball 1022 and is fixedly connected with the rolling ball 1022. Because outer pole 1011 and spin 1022 are fixed connection relation, consequently, can drive spin 1022 at spacing groove 1023 internal rotation through outer pole 1011, outer pole 1011 has constituted the whole shape of implanting the apparatus, through spin 1022 in the free rotation of certain extent promptly, has realized implanting the three-dimensional direction of apparatus and interbody fusion cage and has adjusted.

The core rod 1012 is composed of a linkage portion 1012A and a driving portion 1012B, the driving portion 1012B is connected with the outer rod 1011 by screw thread fit, the linkage portion 1012A and the driving portion 1012B can rotate relatively, and only axial displacement can be performed between the linkage portion 1012A and the outer rod 1011. Specifically, a spherical groove is formed in the lower end surface of the driving portion 1012B, a connection ball is formed in the upper end of the linkage portion 1012A, the connection ball is inserted into the spherical groove and can rotate in the spherical groove, a guide fin and a guide groove are formed between the linkage portion 1012A and the outer rod 1011 to prevent the linkage portion 1012A from rotating, and the linkage portion 1012A is restricted from being axially displaced only in the outer rod 1011 by the cooperation of the guide fin and the guide groove. When the driving portion 1012B is rotated, the driving portion 1012B can move inward due to the thread fit, and further the linking portion 1012A is driven to move inward, so as to achieve the purpose of implementing the stem 1012 at the control end, and due to the existence of the thread, when the stem 1012 reaches a certain position, a certain locking effect can be achieved.

When the angle between the implantation rod 101 and the intervertebral cage 2 reaches a desired angle, it is necessary to lock the current state and then perform a subsequent implantation operation. There are many forms of construction which can achieve locking of the state, and it is anticipated that at least two specific forms may be employed:

<4-1 example >: the surface of the limiting groove 1023 of the clamping seat 1021 and the head end of the core rod 1012 of the implanting rod 101 are both provided with a rough layer 3 for increasing friction force, and the rolling ball 1022 is a ball body with a smooth surface.

After the angle is adjusted to the optimum angle, the core rod 1012 is moved inwards by the operation end, the head end of the core rod 1012 and the limiting groove 1023 form a squeezing state, and the contact surfaces of the core rod 1012 and the limiting groove 1023 are rough layers 3 with large friction force, so that the position fixation between the core rod 1012 and the clamping seat 1021 can be realized, namely the state between the implantation rod 101 and the intervertebral fusion device 2 is locked.

<4-2 example >: the surface of the limiting groove 1023 of the clamping seat 1021 is provided with a rubber layer 4, the head end of the core rod 1012 of the implantation rod 101 is provided with a puncture head 1013 capable of puncturing the rubber layer 4, and the rolling ball 1022 is a ball body with a smooth surface.

When the angle is adjusted to the optimum angle, the core rod 1012 is moved inwards by the operation end, the puncture head 1013 at the head end of the core rod 1012 penetrates into the rubber layer 4, thereby realizing the position fixation between the core rod 1012 and the clamping seat 1021, namely, locking the state between the implantation rod 101 and the intervertebral fusion device 2.

After the implantation of the interbody fusion cage is completed, the implantation instrument needs to be separated from the interbody fusion cage so as to be moved out of the human body, and the interbody fusion cage is detained in the spine of the patient. There are many forms of construction which can achieve locking of the state, and it is anticipated that at least three specific forms can be used:

<4-3 examples >: the inner wall of the clamping groove 202 of the intervertebral fusion device 2 is provided with a rough layer 3 for increasing the friction force, and the outer wall of the clamping seat 1021 is also provided with a rough layer 3 for increasing the friction force. When the clamping seat 1021 of the implantation instrument is placed in the clamping groove 202 of the connecting end, due to the existence of the rough layer 3, the clamping seat 1021 of the implantation instrument cannot be easily separated from the clamping groove 202 of the connecting end, and when a certain degree of external force is applied, the clamping seat 1021 can be moved out of the clamping groove 202, so that the two parts are separated.

<4-4 examples >: the implanting apparatus also has a locking control assembly 5 for changing the connection state between the holder 1021 and the interbody fusion cage, the locking control assembly 5 has: locking plug 501A and drag wire 502A.

The locking plug 501A can be matched with the locking socket 203A on the interbody fusion cage to realize the locking between the clamping seat 1021 and the interbody fusion cage body 201. The draw wire 502A is connected to the locking plug 501A to enable the locking plug 501A to be disengaged from the locking socket 203A. The tail end of the drag wire 502A is disposed at the control end of the implantation rod 101, and the drag wire 502A can be pulled at the control end, and besides, the wiring and guiding of the drag wire 502A should be selected according to the requirements of industrial design, and will not be described in detail herein.

<4-5 examples >: the implanting instrument also has a locking control component 5 for changing the connection state between the clamping seat 1021 and the intervertebral fusion device, and the locking control component 5 has: a locking screw 501B and a flexible transmission shaft 502B.

The locking screw 501B can be matched with the locking screw hole 203B on the interbody fusion cage to lock the cassette 1021 and the interbody fusion cage body 201. The flexible shaft is a shaft which has small rigidity and elasticity and can be freely bent and driven. The coupling mechanism is used for coupling two shafts which are not in the same axis and are not in the same direction or have relative motion so as to transmit rotary motion and torque, and the rotary motion and the torque can be flexibly transmitted to any position. The driving flexible shaft 502B is connected with the locking screw 501B, so that the locking screw 501B can be screwed into or out of the locking screw hole 203B. The tail end of the transmission flexible shaft 502B is arranged at the control end of the implantation rod 101, and the transmission flexible shaft 502B can be subjected to torque input at the control end. The wiring and guiding of the flexible transmission shaft 502B are selected according to the requirements of industrial design, and are not described in detail herein.
