Description
Technical Field

Background
With the development of orthopedic sports medicine, injury repair operations such as rotator cuff repair operation, hip labrum repair operation and the like are more and more widely concerned and applied. A common method of revision surgery is to implant an anchor into bone and secure the injured tendon or other tissue to the bone by self-threading the anchor to the bone. The anchor is in the form of a rigid anchor such as a titanium alloy anchor, a PEEK anchor, etc., and a recently developed full suture anchor, which is flexible. At present, in the process of implanting the full-suture anchor, a pre-drilling hole needs to be made on a bone, then the suture anchor is implanted into the hole, or an inserter with the suture anchor is directly hammered and knocked into the bone, in addition, the self-drilling suture anchor inserter carries the suture anchor to be drilled into the bone, finally, the three methods all need to draw the suture to enable the suture anchor entering the bone passage to be knotted, the transverse diameter (vertical to the central axis of the bone hole) of the knotted suture anchor is enlarged and clamped in the bone to complete the fixation of the bone, and the suture on the anchor finishes the fixation of tendons or other tissues through a thread passing device.
The knot forming mode in the prior art is that after a suture anchor enters a bone, a suture is pulled to tighten, displacement of a knot is generated after tightening, the fixed position of the knot has certain randomness, a bone cavity is reserved below the knot, the bone removing amount is large, meanwhile, the knot needs to enter a relatively deep position of the bone when pre-drilling, knocking-in or self-drilling is conducted so as to reserve the allowance of the displacement of the knot, the deeper the hole is, the larger the interference influence between the hole and the hole is, therefore, the number of implanted anchor points in a unit area is limited to a certain extent, and in addition, the fixing strength is limited to a certain extent due to the size and the material of the knot. Meanwhile, the pre-drilling method needs the suture anchor to be aligned with the pre-drilled hole to enter the bone hole when being implanted, the situation that the suture anchor cannot be inserted and cannot be deployed due to deviation can occur, and the pre-drilled hole needs to be drilled again; the knock-in requires hammering of the inserter, applying impact forces to the bone, and may cause additional loss, especially if the bone is small.
Therefore, the research on a novel suture anchor implantation device is of great significance.

The principle of the invention is as follows:
the invention relates to a suture anchor implanting device, which can automatically form knots through friction between a suture anchor and a bone wall: in the drilling process of the device, the nail body rotates and moves downwards at the same time, the far end of the suture anchor at the position of a nail groove (namely a through hole I) of the nail body is firstly contacted with the bone wall of a drilled hole, the suture anchors at two sides of the position move towards the direction of the axial pointed end and the transverse direction opposite to the drilling rotation at the same time relative to the nail body under the action of friction force with the bone wall, the transverse area of the suture anchor at the position is increased under the condition of the same height, and meanwhile, the suture anchor twists to form wrinkles due to the simultaneous movement of the two directions. After the suture anchor is rapidly drilled to the required depth, the transverse area of the suture anchor at the position of the nail groove is larger, and the suture anchor is twisted to form a fold, so that the friction force between the suture anchor and the bone wall is larger, the hole diameter is rapidly expanded, other parts of the suture anchor are driven to approach the position of the nail groove in a spiral mode (the structure with the spiral groove plays a spiral guiding role, so that spiral knots are more orderly), the transverse diameter of the suture anchor at the position is expanded, the hole diameter at the position is further expanded, and the reciprocating operation is carried out, and finally a spiral knot gathered at the position close to the nail groove is formed.
The prior art puts into the hole with the suture anchor of fixed suture earlier, and the suture anchor is in free state this moment, needs to rely on manual tractive fixed suture, drives the suture anchor and shifts up and contract in the hole, and the horizontal size of suture anchor increases gradually and extrudes the bone wall and becomes the knot, and the resistance increases, and when the resistance was greater than the pulling force of fixed suture, the suture anchor was fixed and is accomplished. In this process, the suture anchor moves up in the hole, and therefore the hole depth needs to be deeper than the intended knot formation location, and the amount of bone removed is large. The invention automatically finishes the knotting action in the drilling process without fixed suture traction, thereby controlling the hole depth to be shallower and removing less bone. Meanwhile, in the prior art, the transverse size of the suture anchor knot is increased limitedly by manual traction, and the fixing strength is limited within the traction force.
The working principle of the suture anchor implanting device is as follows:
the drill stem part of the suture anchor implanting device is loaded to an electric tool, a proper operation bone surface position is selected, the suture anchor is slightly stopped after being drilled into a needed depth, the suture anchor automatically forms a spiral knot, the suture anchor is visually checked to be completely inserted into bone tissue, then the self-drilling rod body is drawn out, the nail body and the suture anchor form a composite spiral suture anchor to be fixed in bone, and the fixing suture is fixed to a tendon or other soft tissue or device through a proper tool to form the fixation of the bone and the tendon or other soft tissue or device.
