Description

Mechanical arm applicable to surgery.

Object of the invention

The present Utility Model application has by object the registration of a mechanical arm applicable to surgery that incorporates notable innovations and advantages over current arms used for the same purpose in operations Surgical

More specifically, it refers to an arm mechanical applicable to surgery that is manually scrollable, including at its end means of support to sustain surgical instruments while at the opposite end presents guide means for fixing to fixed support.

Background of the invention

At present, in the field of surgery is well known the use of rigid or articulated arms as complementary element for the surgeon during the interventions Surgical

Specifically, these arms are used as points of support or help to the surgeon since in them the various instruments and accessories to perform an intervention conventional.

However, these arms have large movement or adaptation limitations in certain situations, since their essentially rigid configurations prevent the most appropriate or appropriate arrangement of accessories necessary for the surgeon.

Description of the invention

The present invention has been developed with the in order to provide a mechanical arm applicable to surgery that solve the aforementioned problems by contributing, in addition, other additional advantages that will be apparent from The description that follows.

The mechanical arm applicable to surgery of the This invention, which can be moved manually, includes in its extreme support means to hold instruments surgical while at the opposite end presents guiding means to be fixed fixed support, and is characterized by the fact that it comprises a plurality of bushings joined together defining a elongated body through which a rope is passed so that the elongated body can move and adapt multiple tour settings manually and keep in a fixed condition the previously set travel configuration, having been provided at one end a stop bushing on which a support element that includes the support means is fixed while on the other opposite end of the tow includes a body comprising a threaded end section and a contour section geometric defined by a plurality of straight edges for fit the guide elements.

Thanks to these characteristics, you get a Easy manufacturing element with high flexibility and versatility that facilitates the manipulation of instruments to user or surgeon during a surgical operation.

According to another aspect of the invention, the central bushes are formed by a body that has a noticeably cylindrical section that includes a hollow cavity substantially hemispherical and a second section with a shape substantially spherical to be coupled in the hollow cavity substantially hemispherical of the cap that follows.

Preferably, the support means for hold surgical instruments comprise two elements equidistant discidales arranged on the same axis that includes superiorly a fork that has a tilting crank which acts as a clamping element to fix the instruments surgical between the two discoid elements.

Other features and advantages of the arm mechanical applicable to surgery object of the present invention will be apparent from the description of an embodiment preferred, but not exclusive, illustrated by way of example no limiting in the accompanying drawings, in which:

Description of a preferred embodiment

As shown in figure 1, the arm mechanical applicable to surgery of the present invention, movable manually, includes at its end support means for hold surgical instruments while at the opposite end It presents guide means to be fixed to fixed support. Said arm is essentially constituted by a plurality of bushings (3) linked together that define an elongated body whose interior is passes a tow (17) so that the elongated body can move and adapt multiple travel settings so manual and keep in a fixed condition the configuration of route previously fixed, having been additionally provided in one end a stop bushing (2) on which the support element (1) shown in figure 6 attached to the tow (17) which includes the means of support. At the opposite end from the arm to the aforementioned, an element of guide (5) (see Figure 8) that has a side coupled vertical bar (9) with a lower cap (10) that is fixed to a surgery table (not shown), a threaded bushing (6) that It has a pivot bar (7) with two end stops (8) and the tow (17) which is coupled by means of a threaded body (18). When the threaded bushing (6) is turned clockwise of the watch, the threaded body (18) that cannot turn when its geometric section, preferably, hexagonal guided in a section of same contour in the guide element (5), (see figures 7 and 8) moves to the threaded bushing (6) and the syringe is tensioned (17), that is, the guide element (5) and the threaded body (18) transform a rotation movement into a movement of translation.

The central bushes (3) are formed by a body that has a substantially cylindrical section that includes a substantially hemispherical hollow cavity and a second section with a substantially spherical shape to be coupled in the substantially hemispherical hollow cavity of the bushing (3) that continue, as shown in figure 4. In figure 5, it has been represented a bushing (4) substantially different from the rest of bushings (3) located at the end that joins the element guide (5).

The livelihoods used to hold the surgical instruments comprise two elements discoid (11) and (13) equidistant arranged on the same axis (12) that includes a fork (14) that has a crank (16) articulated superiorly with a pin (15) that acts as a clamping element by simply turning the same, so that the surgical instruments can be fixed between the said two discoid elements (11, 13).

The details, the shapes, the dimensions and others accessory elements, as well as the materials used in the manufacture of the mechanical arm applicable to surgery of the invention may be conveniently substituted by others that are technically equivalent and do not depart from the essentiality of the invention or of the scope defined by the claims to be include below.
