Description

Technical Field

[0001] This utility model belongs to the field of medical devices, and in particular relates to a positioning mechanism for a wire anchor. Background Technology

[0002] Positioning mechanisms for suture anchors are commonly used in medical surgeries, such as rotator cuff repair. Their primary function is to assist surgeons in correctly placing the anchor to secure tissue or materials. The guide sleeve of the positioning mechanism connects to the main body of the locator and guides the insertion direction of the anchor. During surgery, the guide sleeve and anchor pusher need to operate in narrow and complex anatomical environments, requiring instruments with high precision and smooth operation. Medical devices are typically used frequently in hospitals, and each operation can cause minor wear and tear, which can accumulate over time and affect their functionality. Because the anchor pusher in the positioning mechanism slides within the guide sleeve, frequent use leads to wear on the inner wall of the guide sleeve, thus affecting its accuracy and performance. Summary of the Invention

[0003] In view of this, the present invention aims to at least partially solve one of the related technical problems.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A positioning mechanism for a wire anchor includes a guide sleeve, a positioning and clamping mechanism, an anchor push rod, a first mounting base, a connecting structure, a height adjustment mechanism, and an angle adjustment mechanism.

[0006] The guide sleeve is provided with the first mounting base at its end. The first mounting base is connected to the angle adjustment mechanism through the height adjustment mechanism. The connection structure is provided at the bottom of the angle adjustment mechanism.

[0007] The anchor push rod is slidably disposed within the guide sleeve;

[0008] The guide sleeve has a groove on one side and a slot on the other side. The positioning and clamping mechanism is located in the slot and is detachably connected to the outer wall of the guide sleeve. The positioning and clamping mechanism is used to clamp the anchor push rod.

[0009] The positioning and pressing mechanism includes a fixed pressure plate, a pressure plate base, and multiple elastic pressing devices. The multiple elastic pressing devices are arranged on the pressure plate base, and the pressure plate base is set on the fixed pressure plate. The front and rear ends of the fixed pressure plate are connected to the guide sleeve by a screw.

[0010] Furthermore, the elastic clamping device is a rubber roller.

[0011] Furthermore, the height adjustment mechanism includes an adjustment rod, a fixed rod, an adjustment slide, a second mounting base, and two locking structures. The adjustment slide is disposed on the upper part of the fixed rod. One end of the adjustment rod is connected to the first mounting base, and the other end of the adjustment rod is slidably engaged with the adjustment slide. The adjustment rod is locked and fixed to the adjustment slide by the two locking structures. The bottom of the fixed rod is connected to the angle adjustment mechanism through the second mounting base.

[0012] Furthermore, two reinforcing ribs are symmetrically provided at the position where the adjusting rod connects to the first mounting base.

[0013] Furthermore, a guide groove is provided on both the left and right sides of the adjusting groove. The guide groove is located on the fixed rod. The locking structure can slide within the guide groove. The locking structure includes a locking rod, a fixing nut, and two anti-slip pads. The locking rod passes through the adjusting rod and the two guide grooves. The two fixing nuts are symmetrically arranged on the locking rod. One anti-slip pad is correspondingly provided on the inner side of each guide groove.
