Description

Technical Field

[0001] This invention relates to the field of screwdriver technology, specifically a ratchet screwdriver for dental implant impression taking. Background Technology

[0002] Currently, the generally accepted screwdriver for implant impression taking consists of a compact, integrated structure comprising a blade, a straight handle, and a shank. It is used to insert the screw into the mouth via the screw hole on the cover screw or healing cap, or to loosen and remove it after unscrewing it inside the mouth. Alternatively, it can be used to place the abutment and impression post in the mouth and then tighten it. However, many patients have thick buccal soft tissue, obstruction from adjacent teeth, and insufficient mouth opening leading to blind spots in visual and spatial manipulation, especially during gingival reconstruction surgery in the maxillary posterior teeth region when changing the healing cap. Existing general-purpose screwdrivers, with their straight handles, are often unsuitable for the posterior teeth region, causing difficulties in insertion and removal during oral cavity entry. This can easily lead to dislodgement of restorative components, resulting in accidental swallowing or aspiration. Furthermore, most screwdrivers require hand-held intraoral manipulation, and the surgeon's fingers and the patient's soft and hard tissues obstruct the linear field of vision, resulting in poor lighting and inconvenience, especially in the maxillary posterior teeth region. On the other hand, during closed-mouth impression taking of posterior teeth, the impression post occupies too much space in the intermaxillary distance, making screwdriver insertion difficult. Summary of the Invention

[0003] The purpose of this invention is to provide a ratchet screwdriver for dental implant impression taking, in order to solve the problems mentioned in the background art. The general impression taking screwdriver is a straight-handle type, which cannot be operated normally when entering the oral cavity due to the degree of mouth opening, cannot take impressions vertically, and is prone to secondary injury to the patient due to poor lighting in the oral cavity.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a ratchet screwdriver for dental implant impression taking, comprising a first outer shell, a second outer shell, a bent tube, and a torque meter. A spotlight is circumferentially arranged on the inner wall of the bottom of the first outer shell. A battery is located on the back of the outer side of the first outer shell, and the battery is electrically connected to the spotlight and is externally charged. A first inner shell is located inside the first outer shell. A vertical groove is provided on the inner wall of the first inner shell, and a positioning top is provided within the vertical groove. A bent tube is located above the first inner shell. A first ratchet is located within the first inner shell, and a hexagonal screw head is provided within the first ratchet. A torque meter is horizontally fixedly connected to the bent tube near the first outer shell. A cylinder is located at the other end of the bent tube. A second outer shell is located above the cylinder. A second inner shell is located within the second outer shell. A second ratchet is located within the second inner shell, and a Torx head is provided within the second ratchet.

[0005] Preferably, the first outer shell has an opening at the top, and the side of the opening is tightly fitted to the outer circumferential surface of the bottom end of the bend. The first inner shell is slidably connected to the first outer shell. The outer circumferential surface of the first inner shell is tightly fitted to the circumferential surface of the inner wall of the first outer shell.

The circumferential surface of the teeth of the first ratchet is in close contact with the circumferential surface of the inner wall of the first inner shell, and the upper and lower planes of the first ratchet are in close contact with the upper and lower planes of the inner wall of the first inner shell.

[0007] Preferably, a vertical groove is formed on the inner wall of the first inner housing, the opening surface of the vertical groove is directly opposite the vertical surface of the first ratchet, and a support member is fixedly connected to the inner wall of the vertical groove, and there are two support members, one above the other, which are symmetrical to each other.

[0008] Preferably, a pin is fixedly connected inside the support member, and the pin passes through the two support members. A positioning top member is rotatably connected to the support member. The top of the positioning top member is tightly engaged with the teeth of the first ratchet, and the positioning top member is located in the middle of the vertical groove.

[0009] Preferably, the first ratchet has internal hexagonal teeth and an opening at the bottom. A magnet is provided above the internal hexagonal teeth of the first ratchet, and the internal hexagonal teeth are tightly fitted with the hexagonal screw head. The opening at the bottom of the first ratchet, the opening at the bottom of the first inner housing, and the opening at the bottom of the first outer housing are concentric and circular.

[0010] Preferably, one end of a torque meter is fixedly connected to the transverse end of the bent tube near the first outer shell, the other end of the torque meter is fixedly connected to the rear end of the bent tube, the inner wall of the end of the bent tube is provided with an internal thread, the internal thread is threaded to an external thread, the external thread is provided on the outer circumferential surface of the lower end of the cylinder, and the top of the cylinder is fixedly connected to the second outer shell.

[0011] Preferably, the second outer shell is slidably connected to the second inner shell, and both the second outer shell and the second inner shell have openings at their tops, with the openings being concentric and circular.

The second ratchet has an inner perforated tooth, and the inner perforated tooth is connected to a common perforated head.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the existing mold-taking screwdriver is relatively simple, with a straight handle and a gear buckle at the handle end. Due to the length of the screwdriver, it cannot be used properly when the patient's mouth is open. The angle of the curved tube allows for convenient operation inside the oral cavity. Furthermore, a first ratchet is provided below the curved tube, under which the hexagonal screw head is magnetically attracted. At the same time, the length of the lower part of the curved tube is short, making it easy to enter the oral cavity. A spotlight is also provided below the first outer shell, which can effectively operate without causing discomfort in the oral cavity and can also illuminate the operation area.

[0015] Existing screwdrivers are all single-piece designs. This invention adds a detachable cylinder at the rear, effectively utilizing the rear end. During operation, it can be used with a Torx head to take the mold according to the situation on site, which is convenient and quick. When not in use, it can be disassembled for thorough cleaning and maintenance. Attached Figure Description
