Description

Orthopaedics angle screwdriver

Technical field

The utility model relates to a kind of orthopaedics angle screwdrivers.

Background technique

At present there are many kinds of the orthopedic screwdrivers of clinical use, but its knife bar is all straight.Much in special circumstances, such as The fracture patients such as clavicle, shin bone, it is fixed in steel plate screw of being expert at or when removing inside-fixture operation, since operating space is small, cause Operating difficulty increases, and the time extends, or even broken nail occurs, situations such as inside-fixture can not take.Especially fracture of clavicle patient, hand If must often allow patients head to deflect to strong side pole degree, patient still feels time-consuming and laborious using traditional straight screwdriver when art operates. Above situation may make patient generate sense of discomfort, increase infection probability etc., and the disease and psychology to patient all generate bad shadow It rings.Chinese patent CN201620356713.6 and CN20151021178.3 etc. are provided mostly can illuminate, is electronic, replaceable blade The orthopedic screwdriver of first-class mode.The above patent is all without solving the problems, such as the operation difficulty in small space.

Summary of the invention

Time-consuming and laborious present in the narrow bone surgery in operating space in order to solve the problems, such as, the utility model proposes one kind The orthopaedics angle screwdriver that structure is simple and convenient to operate.

Orthopaedics angle screwdriver described in the utility model, including handle, knife bar and cutter head, the handle are mounted on institute The handshake part of knife bar is stated, the cutter head is mounted on the cutting part of the knife bar, it is characterised in that: the knife bar is angle knife bar, Including the first knife bar, the second knife bar and bolt, the first knife bar installs handle as the first end of handshake part, and the of the first knife bar Two ends are hinged by the first end of bolt and the second knife bar, and the second end of the second knife bar is axially arranged with along it for installing cutter head Concave hole；The installation end of the cutter head is inserted into the concave hole of the second knife bar, and is detachably connected with therewith.

The second end of first knife bar is equipped with the second internal thread hole that can be spirally connected with bolt；The first end of second knife bar is matched There are two mounting ear positioned opposite, there are the card slot of the second end for being inserted into first knife bar between two mounting ears, Second internal thread hole is respectively provided on two mounting ears, and two the second internal thread holes are coaxial；The second of first knife bar After the card slot of second knife bar is inserted at end, and keep the first internal thread hole, two the second internal thread holes coaxial, the bolt rotation Enter in first internal thread hole and the second internal thread hole, the first knife bar of realization is spirally connected with the second knife bar.

The concave hole inner wall coating can adsorb the magnetosphere of top guide.

The concave hole is interior hexagonal structure, and the installation end of the cutter head is the outer-hexagonal that can cooperate with interior hexagonal structure Type.

The end of the cutter head is hexagonal, blossom type or other suitable shapes.

The angle of first knife bar and the second knife bar is 0~180 °.

The technical concept of the utility model are as follows: it is narrow that the design of the variable-angle of screwdriver angle knife bar can solve orthopaedics In space perform the operation row Fracture internal fixaiion or remove inside-fixture when operating difficulties the problem of.Especially fracture of clavicle related surgical When, the design more meets human dissection, physiological characteristic.

Specific embodiment: for removing right side fracture of clavicle inside-fixture operation.Inside-fixture is completely exposed in art, The cutter head of the design screwdriver corresponding with cap nut is selected to be inserted into the second end of the second knife bar such as hexagonal cutter head, pass through Pulling the first knife bar makes the first knife bar and the second knife bar angle be threaded to 90 ° of positions, and handle is placed on the right side of patient, the cutter head of screwdriver After suiting with screw cap, handle, rotation to patient left side are pulled.Patient's neck blocks handle at this time, prevents its continuation left-handed.Art Person can utilize the hinge arrangement of knife bar, by about 180 ° of rotatable handle to patient right side, pull handle, rotation to a patient left side again Side.It operates, screw can be screwed out repeatedly, and do not have to that patient is allowed extremely to make rotation neck.

The utility model has the following beneficial effects: the hinge design of (1) knife bar distal end more meets human body solution in clinical use It cuts open, physiological characteristic, screwdriver is made to rotate freely use in a limited space；(2) structure is simple, at low cost, easy to operate；(3) may be used Cutter head of different shapes is had according to different types of patient production.
