Description

SURGICAL INSTRUMENT FOR ORTHOPEDICS.
DESCRIPTION
The present invention relates to an orthopaedic surgical instrument.
In particular, the surgical instrument according to the present invention is designed to facilitate the creation of a tunnel or hole passing through a bone to enable the introduction of a suture thread. One example of an intervention for which the surgical instrument according to the present invention is particularly useful is the reattachment of a rotator cuff. As is well known, this intervention entails reattaching an end of the injured ligament, which is normally the end towards the arm, at the head of the humerus. The reattachment is achieved by creating a tunnel or hole passing through the tuberosity of the head of the humerus. This hole is used to pass through a suture thread, which is tied to the end of the ligament in order to fix it to the head of the humerus.
At present, the tunnel or through hole is created with an elongate burr, manoeuvred and oriented in a substantially manual manner. In practical terms, the burr is inserted into the shoulder, following the creation of an incision in the tissues, and guided solely by virtue of the sensitivity of the surgeon. Therefore, it is not infrequent for the hole to be created in an incorrect position and orientation. Moreover, an incorrect positioning or an incorrect orientation of the burr may cause serious injuries to the patient. The object of the present invention is to offer a surgical instrument that enables the drawbacks of current instruments to be overcome.
One advantage of the surgical instrument according to the present invention is that it enables a tunnel or through hole to be created in a safe and precise manner, strongly limiting the possibility of an incorrect positioning or an incorrect inclination of the hole itself.
Another advantage of the surgical instrument according to the present invention is that it renders the surgical intervention easier and safer.
Additional features and advantages of the present invention will become 2 more apparent from the detailed description that follows of one embodiment of the invention in question, illustrated by way of non-limiting example in the appended figures, in which:
- figure 1 shows a sectional view of the surgical instrument according to
5 the present invention, taken on a plane containing a longitudinal axis
(X);
- figure 2 shows an isometric view of the surgical instrument according to the present invention.
The surgical instrument according to the present invention comprises a
10 handle (2) with which a tubular guide (3) is associated.
The tubular guide has a longitudinal axis (X) and has a first end (31) and a second end (32) which are open so as to allow the introduction and sliding of an elongate tool (N).
The elongate tool (N) is an instrument designed to create a tunnel or
15 hole passing through a bone. For this purpose, the elongate tool (N) has a pointed or sharp terminal (T), structured so as to perforate a bone. The tool (N) is inserted into the tubular guide (3) with the terminal (T) turned towards the second end (32) of the tubular guide (3). For example, the elongate tool (N) is a burr or a K wire.
20 Advantageously, the instrument according to the present invention comprises an abutment (4), disposed at the second end (32) of the tubular guide (3), which abutment has a first portion (41), structured so as to be able to rest on a first area of a bone surface (B).
The presence of the abutment (4), endowed with the first portion (41),
25 together with the presence of the tubular guide (3), enables the tool (N) to be guided with great precision. In fact, the surgeon, after having introduced the abutment element (4) into the incision made in the patient, and after having rested the first portion (41) on the bone surface, can maintain the tubular guide (3) in a stable position with one hand, by
30 gripping the handle (2), while he/she can manoeuvre the tool (N) with the other hand. The first portion (41) stably and precisely defines the entry 3 position of the hole drilled by means of the tool (N). The tubular guide (3) defines the direction of the hole, guiding the tool (N) along the longitudinal axis (X).
In order to facilitate the manoeuvring of the tool (N), the first end (31) of
5 the tubular guide (3) projects or faces an end of the handle (2).
Preferably, but not necessarily, the abutment (4) comprises a second portion (42), structured so as to be able to rest on a second area of a bone surface (B) that is distinct from the first area.
The presence of the second portion (42) makes it possible to further
10 increase the stability and precision of the positioning of the tubular guide (3), and therefore also the precision and correct orientation of the hole created by means of the tool (N). In fact, resting both portions (41 ,42) of the abutment (4) on the bone surface enables the inclination of the longitudinal axis (X) to be defined with precision on a plane passing
15 through the points of contact between the portions (41 ,42) and the bone surface.
Preferably, the first portion (41) and the second portion (42) are disposed in such a way as to define a concave surface, whose concavity faces towards the longitudinal axis (X). This arrangement favours the
20 resting of the two portions (41 ,42) on the tuberosity of the head of the humerus, or in general on a bone surface with a convex shape. Moreover, the free end (42a) of the second portion (42) is disposed in proximity to the longitudinal axis (X). In this manner, the free end (42a) lies in proximity to the exit of the hole drilled by means of the tool (N).
25 In the preferred, but non-exclusive, embodiment illustrated, the first portion (41) and the second portion (42) are substantially rectilinear and inclined relative to each other so as to define overall the concave surface. Moreover, the first and second portions (41 ,42) are coplanar with the longitudinal axis (X). This makes it possible to visually identify, in a clear
30 and immediate manner, the plane in which the longitudinal axis (X) lies. In this manner, the intervention of the surgeon is facilitated considerably, as 4 the latter is able to clearly perceive, at the moment of introduction, the plane in which the longitudinal axis (X) lies, and thus the plane in which the hole drilled by means of the tool (N) lies.
Preferably, the second portion (42) has a through slot (43). The slot (43) 5 can be open or closed. In the former case, the slot (43) is delimited by an open outline, i.e. an outline interrupted at an opening, whereas in the latter case the slot (43) is delimited by a continuous closed outline. The slot (43) is useful for retaining a suture thread, which can be introduced into the site of the intervention. The slot (43) is preferably disposed at the free end 10 (42a) of the second portion (42). This allows the suture thread to be retained in proximity to the exit of the hole drilled by the tool (N). In this manner, the thread can be easily engaged and drawn into the hole itself by means of specific hooked instrument, which can be introduced into the tubular guide (3) following the extraction thereof from the tool (N).
