Description

Support for Kirschner wire

Technical Field

The utility model relates to a medical apparatus, in particular to a bracket for a Kirschner wire.

Background

Kirschner wire and traction bow are instruments used for bone reduction in orthopedics dislocation patients, and as shown in the specification of CN 208404800U, figure 7 shows the traction bow and Kirschner wire combined together. The k-wire is used to penetrate the bone, the traction bow is used to connect with weights, etc., and a pulling force is applied to the k-wire mounted to the traction bow, thereby resetting the dislocated bone.

Taking the heel as an example, a Kirschner wire after passing through bone, a physician would normally want the Kirschner wire to remain in a relatively stable plane all the time; the Kirschner wire is suspended in the air at both ends after passing through the heel of the patient, so that if the patient turns over at night, the Kirschner wire at the heel often tilts, and the Kirschner wire deviates from the originally set plane, which may affect the direction of the force line on the bone under traction, and affect traction treatment.

Disclosure of Invention

In view of the above problems, the present utility model aims to provide a holder for a k-wire, which can support the k-wire on both the left and right sides of the k-wire, ensuring that the k-wire does not incline.

The present utility model provides a holder for a k-wire, comprising: a base member, a support member;

the base member includes: a flat base body and a screw; the screw rod is formed on the upper side surface of the base body in an upward extending manner; the screw is provided with a first nut and a second nut;

the support member includes: collar, side support bar and combining block; the lantern ring is used for being sleeved on the screw rod of the base member and clamped between the first nut and the second nut, and the position of the supporting member on the screw rod of the base member is adjusted by adjusting the heights of the first nut and the second nut, so that the height of the whole bracket for the Kirschner wire is adjusted; the side support rods are respectively fixed at the left side and the right side of the lantern ring; the combining blocks are fixed at the top ends of the side supporting rods at the left side and the right side of the lantern ring; a Kirschner wire jack is formed in the middle of the combining block; the top end of the combining block is provided with a screw hole which extends downwards and is communicated with the Kirschner wire jack; a screw is arranged in the screw hole; the end of the screw is abutted against the peripheral surface of the Kirschner wire in the Kirschner wire inserting hole so as to fix the Kirschner wire.

Preferably, the base member has an annular weight mounted thereon; the annular weight is sleeved at the bottom of the screw.

The support for the Kirschner wire is respectively supported at the two ends of the Kirschner wire, so that the Kirschner wire is supported at the two ends of the Kirschner wire, and the Kirschner wire is effectively prevented from being inclined accidentally.

Detailed Description

The holder for k-wire according to the present utility model will be described in detail with reference to the accompanying drawings.

The present utility model provides a holder for a k-wire, comprising: a base member and a support member.

The base member includes: a flat base body 10 and a screw 11.

The screw 11 is formed on the upper side of the base body 10 to extend upward; the screw 11 is provided with a first nut 12 and a second nut 13. The first nut 12 and the second nut 13 are threadedly engaged on the screw 11.

The support member includes: collar 20, side support bar 21, joint block 22.

The collar 20 is used to be sleeved on the screw 11 of the base member and clamped between the first nut 12 and the second nut 13, and the position of the supporting member on the screw 11 of the base member is adjusted by adjusting the heights of the first nut 12 and the second nut 13, so that the height of the whole support for the k-wire is adjusted to adapt to specific height requirements.

The side support rods 21 are respectively fixed on the left side and the right side of the lantern ring 20; the combining blocks 22 are fixed at the top ends of the side supporting rods 21 at the left and right sides of the collar 20; a Kirschner wire insertion hole 23 is formed in the middle of the combining block 22; the top end of the combining block 22 is provided with a screw hole 25, and the screw hole 25 extends downwards to be communicated with the Kirschner wire jack 23; screw holes 25 are provided with screws 24; the tip of the screw 24 abuts against the peripheral surface of the k-wire 30 in the k-wire insertion hole 23 to fix the k-wire.

An annular weight (not shown) is mounted on the base member; the ring-shaped weight is fitted over the bottom of the screw 11, thereby increasing the weight of the base member and making the base member more stable.

When in use, as shown in figure 1, two brackets for the Kirschner wire are respectively supported at the left end and the right end of the Kirschner wire, wherein the Kirschner wire is inserted into a Kirschner wire jack of the corresponding bracket; the positions of the first and second nuts on the bolts of the corresponding brackets are adjusted so that the brackets are at a proper height so that the k-wire is on a desired plane (usually a horizontal plane). When a patient turns over, the Kirschner wire cannot incline due to the limitation of the brackets at the two sides, so that the correct traction force line of the patient is ensured.
