They are generally categorized as straight quick-release handles and T-shaped quick-release handles. Straight quick-release handles are typically used with orthopedic screwdrivers to install implants at lower torques, while T-shaped handles are typically used with orthopedic taps to tap bone tunnels and with orthopedic screwdrivers to install implants at higher torques.

[0003] Existing handles include straight handles (such as Figure 8 As shown), the axis of the instrument is parallel to the axis of the handle after the instrument is connected; there is a T-shaped handle (as shown Figure 9 As shown), after the instrument is connected, the instrument axis is perpendicular to the handle axis; the handle is converted horizontally and vertically (as shown Figure 10 As shown), there are two instrument connection ports. When the instrument is connected from port 1, it is in a straight handle state, and when the instrument is connected from port 2, it is in a T-handle state.

[0004] The above-mentioned prior art has the following problems:

[0005] 1. When a larger torque is required to install the implant, the straight quick-release handle cannot provide sufficient force and needs to be replaced with a T-handle;

[0006] 2. After using a T-handle with an orthopedic tap to complete the tapping of a bone tunnel, the large rotation radius of the T-handle affects the speed of the tap's reverse rotation when withdrawing the tap, increasing the operation time.

[0007] 3. When preparing surgical instruments, two different types of quick-release handles need to be prepared at the same time, which increases production costs;

[0008] 4. During the operation, different handles must be replaced to meet different usage requirements. The surgical steps are cumbersome, which increases the operation time and the error rate. Utility Model Content

DETAILED DESCRIPTION

[0030] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0031] The utility model provides a foldable T-shaped quick-release handle, such as Figure 1-5 As shown, it includes a handle body 1, one end of the handle body 1 is fixedly connected to a connecting end 2, and a group of symmetrical storage grooves 3 and slide grooves 4 are opened on the handle body 1, wherein a folding mechanism 5 is provided in each storage groove 3, and a sliding mechanism 6 is elastically installed inside the handle body 1, and both ends of the sliding mechanism 6 are slidably installed in the slide groove 4, one end of the folding mechanism 5 is hinged to the end of the storage groove 3, and the other end of the folding mechanism 5 is hinged to the sliding mechanism 6. Pushing the sliding mechanism 6 makes the other end of the folding mechanism 5 move in the storage groove 3, so that the folding mechanism 5 forms a conical or horizontal state, and a locking mechanism 7 is provided at the end of the handle body 1.

[0032] In the straight handle form, the folding mechanism 5 is stored in the storage groove 3 of the handle 1, forming a complete cylinder with the handle body 1;

[0033] When it is necessary to use an orthopedic screwdriver to install an implant with a larger torque or to use an orthopedic tap to complete bone tunnel tapping, the sliding mechanism 6 is pushed toward the tail of the handle body 1, and the sliding mechanism 6 drives the folding mechanism 5 to move and gradually unfold to form a T shape with the handle body. The sliding mechanism 6 is further pushed toward the tail of the handle body 1, and the sliding mechanism 6 and the snap mechanism 7 are locked, completing the switching of the T-shaped handle form;

[0034] When the orthopedic tap needs to be quickly withdrawn after completing bone tunnel tapping, the upper and lower snap mechanisms 7 are pressed simultaneously to release the lock. At this time, the sliding mechanism 6 and the snap mechanism 7 automatically return to the straight handle shape under the elastic force. Since the turning radius is reduced, the tap can be quickly withdrawn.

[0035] The quick-release handle can be switched between the T-shaped handle and the straight handle at will, which not only reduces costs but also shortens operation time and the error rate of operation.

[0036] Furthermore, the folding mechanism 5 includes a rear link 51 hinged at the end of the storage slot 3 and a front link 52 hinged at the top of the sliding mechanism 6. The rear link 51 and the front link 52 are hinged. The width of the rear link 51 is greater than that of the front link 52. A connecting groove 511 is provided at one end of the rear link 51 close to the front link, and one end of the front link 52 is hinged in the connecting groove 511. The storage slot 3 has a T-shaped structure. The outer surfaces of the rear link 51 and the front link 52 are designed to be arc-shaped and have the same curvature as the handle body 1, so that the rear link 51 and the front link 52 can remain horizontal with the handle and be spliced ​​to form a complete cylindrical structure.

[0037] Furthermore, the sliding mechanism 6 includes a slider 61 movably installed inside the handle body 1. The slider 61 has a cross-shaped structure, and its two ends extend into the slide groove 4 and slide in contact with the slide groove 4. The rear end of the slider 61 is connected to a first spring 62. In the initial state, the slider 61 is located at the front end of the slide groove 4 under the elastic force of the first spring.

[0038] Furthermore, the locking mechanism 7 includes a mounting groove 73 opened at the end of the handle body 1 and two clips 71 hinged in the mounting groove 73. The mounting groove 73 is provided with an arc groove 731 for the movement of the clip 71. The two clips 71 are designed to be symmetrical on the left and right. Blind holes 712 are opened at the ends of the opposite sides of the two clips, and a second spring 72 is connected between the two blind holes 712.

[0039] The slider 61 has a cross-shaped structure, wherein the upper and lower ends are used to hinge the folding mechanism 5, and slide grooves extend from the left and right ends, and a boosting structure 612 is fixedly connected to the end. The boosting structure 612 makes it convenient for the staff to use the thumb and index finger to clamp the slider 61 and push it. At the same time, the inner side of the boosting structure 612 contacts and abuts against the handle body 1 to enable the slider 61 to move stably inside the handle body 1.

[0040] Furthermore, an insertion rod 611 is provided at the rear end of the slider 61, and a slot is provided at the tail of the insertion rod 611, wherein the first spring 62 is sleeved on the insertion rod 611, and a hook 711 is provided at the front end of the buckle 71, and the hook 711 and the slot provided at the tail of the insertion rod 611 are adapted to each other.

[0041] The working principle of this utility model:

[0042] In the straight handle configuration, the rear connecting rod 51 and the front connecting rod 52 are stored in the storage groove 3 of the handle 1, forming a complete cylinder with the handle body 1;

[0043] When it is necessary to use an orthopedic screwdriver to install an implant with a larger torque or to use an orthopedic tap to complete bone tunnel tapping, the slider 61 is pushed toward the rear end of the handle body 1, and the slider 61 drives the front connecting rod 52 to move. Under the action of the hinge, the rear connecting rod 51 and the front connecting rod 52 are gradually unfolded into a T shape with the handle body 1. The slider 61 is further pushed toward the rear end of the handle body 1, and the insertion rod 611 is locked with the buckle 72. At this time, the hook 711 is embedded in the card slot, completing the switch to the T-shaped handle form;

[0044] When the orthopedic tap needs to be quickly withdrawn after completing the bone tunnel tapping, the upper and lower buckles 71 are pressed simultaneously to release the lock. At this time, the slider 61 and the buckle 71 automatically return to the straight handle shape under the elastic force of the first spring 62. Since the turning radius is reduced, the tap can be quickly withdrawn.

[0045] The quick-release handle can be switched between the T-shaped handle and the straight handle at will, which not only reduces costs but also shortens operation time and the error rate of operation.

[0046] Several points should be explained: First, it should be noted that in the description of this application, unless otherwise specified or limited, the terms "mounted", "connected", and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection.
