Abstract
A bone tunnel combined drill device belongs to a surgical instrument. The device comprises an operation drill and a protective sleeve, wherein the operation drill comprises a handle part, a rod part and a head part, the head part comprises two stepped parts with small front parts and larger rear parts, and the two stepped parts are respectively provided with a helical cutting edge; and the protective sleeve comprises series of hollow sleeves with different diameters, the hollow sleeves can be combined and sleeved together, and the operation drill can penetrate through the hollow sleeve with maximum diameter. By adopting the corresponding hollow sleeve to protect the drill bit, the working cutting edge is prevented from unnecessarily hurting muscles on lateral sides when the drill bit is in operation.
Description
Technical field
This utility model relates to a kind of surgical operating instrument, relates to a kind of osseous tunnel associating boring device particularly.
Background technology
Anterior cruciate ligament (anterior cruciate ligament, ACL) fracture is common and serious athletic injury, malpractice will cause instability of knee, cause that a series of backs something lost changes, have a strong impact on the motion of knee joint function, therefore, its clinical research and treatment are important topics in orthopaedics and athletic injury field always, are paid attention to by numerous experts, scholars.To the treatment of ACL fracture, the method that often adopts ligament to rebuild.The method for reconstructing of cruciate ligaments of knee joint fracture is a lot, but generally all needs to set up osseous tunnel.Set up osseous tunnel and need use bone drill, but present used bone drill often has only drill bit or pin, in piercing the process of bone,, easily cause unnecessary strand to hinder muscular tissue on every side owing to lack protection.Again or have some devices that the band sleeve is arranged, but often have only the sleeve of a diameter, during use, the muscle in the sleeve diameter scope all can sustain damage.
The utility model content
The purpose of this utility model is at the existing in prior technology deficiency, and a kind of step-like osseous tunnel associating boring device is provided.This osseous tunnel associating boring device can be used for the foundation of step-like osseous tunnel, particularly is applied to keep in the foundation of osseous tunnel in the Healing in Anterior Cruciate Ligament Reconstruction operation of vestiges the muscular tissue around can protecting.
The technical scheme that this utility model provides is as follows:
A kind of osseous tunnel associating boring device, comprise surgical drill and protection sleeve, it is characterized in that: described surgical drill comprises a shank, a bar portion and a head, described head is pre-small post-large step-like two parts, and described step-like two parts respectively have spiral helicine cutting edge; Described protection sleeve comprises the serial cannulated sleeve of different-diameter size, and this series cannulated sleeve is capable of being combined to be nested in together, and wherein the cannulated sleeve inside of diameter maximum can be passed by described surgical drill.
Described surgical drill head longitudinal section be step-like two cylindrical.
Described surgical drill head longitudinal section is two step-like taper shapes.
Described surgical drill head longitudinal section is that a step-like taper shape and one are cylindrical.Can be anterior for cylindrical, the rear portion be conical, also can be anterior for conical, and the rear portion is cylindrical.
Described cannulated sleeve is a hollow cylinder.
Described cannulated sleeve is a hollow cylinder, and its head has an oblique section, and afterbody has one handle, is used to control.
According to the above; the utlity model has following advantage: the protection sleeve of employing comprises the serial cannulated sleeve of different-diameter size; when setting up the tunnel; can be by sleeve from fine to coarse; progressively enlarge the mode of boring; expand the hole muscle on every side that spuds in, the muscle that originally is positioned at the boring scope is expanded open, reduced muscle injury.Because adopted corresponding cannulated sleeve protection drill bit, when therefore having avoided drill bit work, its working edge is hindered the unnecessary strand of lateral muscular tissue; Drill bit head is pre-small post-large step-like, can set up step-like osseous tunnel, and helps the drill bit work efficiency and improve.

The specific embodiment
A kind of osseous tunnel associating boring device of this utility model development is formed by uniting brill and protection sleeve two parts.Gen Ju Hams length and diameter are made to unite and are bored and protection sleeve.30 Li Yong Hamses are rebuild the patient of front and back ligamentaum cruciatum, length after measurement semitendinosus m. tendon, gracilis tendon take out, semitendinosus m. tendon length 27.8 ± 2.14cm (24～32cm) as a result, (diameter of 23～30cm), four strands of semitendinosus m. gracilis tendons is 7.47 ± 0.51cm (7～8cm) to gracilis tendon length 26.2 ± 1.99cm.Patient to 50 examples are rebuild ACL with isometric technology measures the femur length of tunnel, found that the femur length of tunnel is 5.81 ± 0.47cm (5～6.5cm).Therefore design the hollow brill of uniting of special step sample of six kinds of different sizes, the foundation in femur bottleneck sample bone tunnel is guaranteed in the application of uniting brill.
Sleeve in the specific embodiment of the utility model, with reference to figure 1 and Fig. 2, the serial cannulated sleeve 1,2,3,4,5 that is 5 different-diameters is formed, and promptly is respectively diameter 4mm length 200mm, diameter 6mm length 160mm, diameter 8mm length 120mm, diameter 10mm length 100mm, diameter 12mm length 80mm.Wherein cannulated sleeve 1～3 is a hollow cylinder, and sleeve cannulated sleeve 5 is a hollow cylinder, and its head has an oblique section, and afterbody has one handle.This series sleeve can be nested together, as shown in Figure 2.
Referring to Fig. 3～5, Fig. 3～5 are respectively perspective view, planar structure sketch map and the side view of this utility model embodiment surgical drill.This surgical drill 6 comprises shank 61, bar portion 62 and head 63, and wherein shank 61 is the position that fixes with the electric drill instrument, in the present embodiment, shank 61 cross sections are a pentagon, yet are not limited thereto, and shank can be according to the shape of the insertion portion of electric drill instrument and the shape of design.This bar portion 62 is one cylindrical.The head of this surgical drill comprises and is pre-small post-large step-like front portion 63 and rear portion 64 that described step-like front portion 63 and rear portion 64 respectively have spiral helicine cutting edge.
Surgical drill part of the present utility model is made up of the surgical drill of the same race of six different-diameter specifications, only shows a structural representation among the figure, and all the other are not because the structure unanimity repeats diagram.Anterior 63 diameters of surgical drill head are 6～8mm, and rear portion 64 diameters are 11～12mm.Every kind of specification drill bit all can carry out work by a cannulated sleeve (diameter 12mm length 80mm) of diameter maximum.
When a kind of osseous tunnel associating of this utility model boring device uses, use the sleeve 1 of diameter minimum to insert the skeleton position of muscular tissue earlier, outside sleeve 1, be inserted in the big slightly sleeve of diameter 2 then, and sleeve pipe 2 also arrives this skeletal sites to required punching, extract sleeve 1 again, retention sleeve 2 in position; Be inserted in the diameter sleeve 3 bigger slightly afterwards than sleeve 2; extract sleeve 2; so repeat; progressively excessively arrive the sleeve 5 of diameter maximum; the drill bit 6 of reuse inserts in the sleeves 5 and carries out work (as shown in Figure 6), owing to during each drill bit rotary work, all be with corresponding cannulated sleeve protection outward; when therefore having avoided drill bit work, its working edge is hindered the unnecessary strand of lateral muscle or skeleton.
Above-mentioned only is a specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that this utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading this utility model protection domain.
