Description

Artificial stapes implanter

Technical Field

The utility model relates to a medical supplementary surgical instruments field, concretely relates to artifical stapes implantation device.

Background

During the operation of an otomicroscope or otoscope for the implantation of an artificial stapes, the implantation of an artificial stapes generally takes place in the following manner:

1: the McLee forceps are used for clamping the artificial stapes to implant, and the clamped position and angle need to be adjusted in the implantation process, so the operation is difficult, and the McLee forceps are not suitable for an underwater operation mode for implanting the artificial stapes in an ear endoscope, because in the underwater operation mode, when the position and the angle for clamping the artificial stapes are adjusted, water flow washes away the artificial stapes;

2: the suction apparatus sucks the hook of the artificial stapes to implant, the operation is relatively simple, but the artificial stapes is easy to fall off in the operation process, the direction of the hook of the artificial stapes is not easy to control, and the suction apparatus is not suitable for an underwater operation mode for implanting the artificial stapes in the ear endoscope, because the suction apparatus cannot suck the hook of the artificial stapes in the underwater operation mode, the artificial stapes is flushed away by water;

3: the method is difficult to operate and is not suitable for an underwater operation mode of the artificial stapes implantation of the ear endoscope, because in the underwater operation mode, the artificial stapes can be washed away by water flow;

at the present stage, because of good operation visual field, the underwater operation mode of the ear endoscope for implanting the artificial stapes becomes more and more mainstream, the conventional artificial stapes implantation mode is not suitable for underwater operation, and at the moment, the underwater operation is usually changed into the non-underwater operation when the artificial stapes is implanted, which undoubtedly increases operation time and difficulty.

Therefore, how to solve the defects of the prior art is a subject of the present invention.

Detailed Description

The present invention will be further illustrated with reference to the accompanying drawings and specific embodiments, which are to be understood as merely illustrative of the invention and not as limiting the scope of the invention.

Example (b): referring to fig. 1-4, an artificial stapes implanting device comprises a casing 100, a push rod 200 is slidably disposed in the casing 100 along a length direction thereof, a sliding groove 101 is formed at an outer end of the casing 100 corresponding to the push rod 200, an operating handle 201 is formed at a top end of the push rod 200 corresponding to the sliding groove 101, and the operating handle 201 extends out of the sliding groove 101 and is in sliding fit with the sliding groove 101;

the left side and the right side of the lower end of the sleeve 100 are respectively provided with a guide groove 102 along the length direction of the sleeve 100, the guide grooves 102 are used for being inserted and matched with a hook part of an artificial stirrup, and the bottom end of the push rod 200 is correspondingly arranged above the guide grooves 102;

when the artificial stapes are implanted, firstly, the hook-shaped artificial stapes are inserted into the lumen of the cannula 100 through the lower end of the cannula 100, and the hook of the artificial stapes is inserted into the guide groove 102, so as to complete the installation of the device; then under microscope or otoscope, aim the lower extreme of sleeve 100 at the opening of stapes bottom plate, push the operation handle 201 downwards so that the end of artificial stapes gets into the stapes bottom plate opening, push the operation handle 201 and roll back sleeve 100 simultaneously, when the artificial stapes is about to break away from sleeve 100 completely, hang the hook of artificial stapes on the incus long foot, accomplish the implantation of artificial stapes this moment.
