Problems solved by technology

[0002] In the minimally invasive operation of orthopedic intramedullary nailing to treat fractures, the operator often needs to use fingers to probe and determine the nail entry point. However, due to factors such as the depth of the nail entry point and the obstruction of surrounding soft tissues, the intramedullary nail cannot be accurately grasped. , often resulting in inaccurate positioning, deviation of the nail entry point, or deviation of the entry direction of the nail, resulting in difficult and repeated surgical operations, thus prolonging the operation time and even increasing the trauma of the operation

Embodiment Construction

[0011] Such as figure 1 As shown, a finger-shaped intramedullary nail guide of the present invention is made of aluminum alloy or stainless steel, and includes a finger sleeve 1 that matches the shape of the finger and an intramedullary nail guide cylinder 2 for guiding the guide wire. The intramedullary nail guide cylinder 2 is fixedly connected to the surface of the finger sleeve 1, and the central axes of the two are parallel. There is an opening 3 parallel to the axis on the surface of the finger sleeve 1, and the finger sleeve 1 can be adjusted by using the opening 3. thickness; the length of the finger sleeve 1 is the distance from the distal interphalangeal joint of the index finger to the proximal interphalangeal joint; when in use, adjust the size of the finger sleeve 1 according to the user’s condition, and then insert the intramedullary nail through Through the intramedullary nail guide cylinder 2, the other hand operates the intramedullary nail, thus avoiding the d...

Abstract

The invention discloses an intramedullary nail finger-type guider which comprises a finger sleeve matched with a finger in shape and an intramedullary nail guiding barrel used for guiding an intramedullary nail. The intramedullary nail guiding barrel is fixedly connected to the surface of the finger sleeve, and the central axis of the finger sleeve is parallel to the central axis of the intramedullary nail guiding barrel. An opening parallel to the axis is formed in the surface of the finger sleeve. The intramedullary nail finger-type guider is simple in structure and accurate in location.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a finger guide for intramedullary nails. Background technique [0002] In the minimally invasive operation of orthopedic intramedullary nailing to treat fractures, the operator often needs to use his fingers to probe and determine the nail entry point. However, due to factors such as the depth of the nail entry point and the obstruction of surrounding soft tissues, the intramedullary nail cannot be accurately grasped. , often resulting in inaccurate positioning, deviation of the nail entry point, or deviation of the nail entry direction, resulting in difficult and repeated surgical operations, thereby prolonging the operation time and even increasing the trauma of the operation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a finger-shaped guider for intramedullary nails with simple structure and...
