Abstract

Provided is a femoral trochanter peak pulp-opening guider. A plane (6) is arranged at the edge portion on one side of a finger guider (1), Kirschner wire guiders (3) are arranged on the plane (6), and a grip (5) is arranged on the other side of the finger guider (1). The finger guider (1) and the Kirschner wire guiders (3) are respectively in a tubular shape, a hole in the finger guider (1) is called a finger guide hole (2), and a hole in each Kirschner wire guider (3) is called a Kirschner wire guide hole (4). One to three Kirschner wire guiders (3) are arranged on the plane (6) of the finger guider (1). The femoral trochanter peak pulp-opening guider helps orthopedists solve the problems of locating inaccuracy and high frequency of X-ray examinations common in the peak locating pulp-opening process for closed reduction of femoral trochanter fracture, X-rays harmful to patients and doctors in operations is reduced, meanwhile operation accuracy is improved, and operation time is shortened.

Description

The marrow guider is driven on the femoral bone tuberosity summit

Technical field

This utility model relates to a kind of bone surgery guider, and particularly the marrow guider is driven on a kind of femoral bone tuberosity summit, belongs to the technical field of medical device aspect.

Background technology

The surgeon operates on to patient by rule of thumb and carries out the femoral bone tuberosity summit and open marrow when performing an operation, there is no guider aspect technology at all, the orthopedist solves the inaccurate perspective in location common in the locating open marrow process of closed reduction femur intertrochanteric fracture summit often, in patient and doctor's operation, seriously, perform the operation simultaneously accuracy and operating time are the maximum worries between orthopedist and patient in the x-ray injury.

Summary of the invention

The purpose of this utility model is to provide a kind of femoral bone tuberosity summit to drive the marrow guider.

This utility model is to realize like this.

The marrow guider is driven on a kind of femoral bone tuberosity summit, limit section in finger guides (1) one side is provided with plane (6), (6) are upper on plane, are provided with Kirschner wire guider (3), at the opposite side of finger guides (1), are provided with handle (5).

Finger guides (1) all is tubular with Kirschner wire guider (3).

Hole in finger guides (1) is called finger pilot hole (2).

Hole in Kirschner wire guider (3) is called Kirschner wire pilot hole (4).

Outerplanar (6) in finger guides (1) is upper, is provided with one to three Kirschner wire guider (3), and the about 2mm to 8mm in (6) bottom locates three Kirschner wire guiders (3) on plane.

Finger guides (1) is made with metal or plastics.

The internal diameter 20mm of finger guides (1).

Handle (5) is the free arc wire.

This utility model is that to help the orthopedist to solve location common in the locating open marrow process of closed reduction femur intertrochanteric fracture summit inaccurate, and perspective often, reduces x-ray injury in patient and doctor's art, improves simultaneously the operation accuracy and shortens operating time.

The accompanying drawing explanation

Fig. 1 is plan structure schematic diagram of the present utility model;

Fig. 2 is the right TV structure schematic diagram of Fig. 1.

In figure: 1 finger guides, 2 finger pilot holes, 3 Kirschner wire guiders, 4 Kirschner wire pilot holes, 5 handles, 6 planes.

The specific embodiment

As shown in Figure 1, the marrow guider is driven on a kind of femoral bone tuberosity summit, is the accurate guider of a kind of bone surgery.Finger guides 1 is poroid metal object, and also available plastics are made.The internal diameter 20mm of finger guides 1, section is provided with plane 6 on the limit of an example, at the opposite side of finger guides 1, is provided with handle 5, and described handle 5 is the use of holding for orthopedist's handled easily.Described handle 5 is the free arc wire.The poroid finger pilot hole 2 that is called in finger guides 1.On the plane 6 of finger guides 1, be provided with three Kirschner wire guiders 3, the endoporus of described Kirschner wire guider 3 is called Kirschner wire pilot hole 4.

The 6 about 2mm to 8mm in bottom locate described three Kirschner wire guiders 3 on plane.

Using method: cut after suffering from the limb traction closed reduction under the non-direct-view of skin and touch femoral bone tuberosity greater trochanter summit, hand-held this utility model will lead and be placed in Kirschner wire pilot hole 4 with Kirschner wire this moment, first finger is placed in finger pilot hole 2, then can the one-handed performance guiding touch simultaneously the greater trochanter summit with the position all around of Kirschner wire, after touching clearly, squeeze into the guiding Kirschner wire, squeeze into during Kirschner wire to have an X-rayed and according to practical situation, change Kirschner wire and be positioned at Kirschner wire guiding, 4 position.This device makes operation technique doctor one-handed performance guiding with the squeezing into of Kirschner wire in operating process, reduced because of two hand operateds cause range of operation large, and the perspective machine is put inconvenience, leads and fixes the problems such as inaccurate and not firm with Kirschner wire.
