Description

Medical half-tube fracture reduction fixator

Technical Field

The utility model relates to the technical field of surgical instruments, in particular to a medical half-pipe fracture reduction fixator.

Background

In the existing orthopedic surgery, a kirschner wire or a bone round wire is often required to fix the fracture, the kirschner wire or the bone round wire penetrates through the center of a bone, the holding force is the largest, and the fixation is the firmest. However, the long bone is basically cylindrical and smooth in surface, so that the kirschner wire is easy to slide on the surface of the bone and deviate from the preset position, fixation failure occurs, particularly, closed needle insertion is often needed along with the development of the orthopedic surgery in the minimally invasive direction, the whole bone appearance cannot be seen, and in addition, the skin, fascia and muscle around the bone are obstructed, the operation difficulty is high, the fixation needle is easy to slide, the drilling deviation occurs, repeated drilling occurs, and even iatrogenic fracture occurs. One end of the prior art orthopedic reduction tool in the form of a clamp, which contacts a bone, is in point contact with opposite forces, which is symmetrical to each other, that is, two symmetrical force application points can contact each other when the orthopedic reduction tool is closed. However, in a complicated or special human anatomy position or a narrow operation area, two symmetrical tip force application points of the reduction forceps cannot be simultaneously accommodated, or the insertion direction of the reduction forceps can appear, or important nerve vessels which cannot be avoided exist in an insertion channel, and the conventional reduction fixing forceps cannot meet the situation.

The prior art, the application number is: CN201820371637.5, patent name: the utility model provides an orthopedics doctor is with direction pincers that reset, discloses an orthopedics doctor is with direction pincers that reset, including pincers handle one, binding clip, articulated elements, extension pincers handle, ring, go up latch, bolt, adjusting nut, hollow guide sleeve, pincers handle two and lower latch, pincers handle one and two upper portions of pincers handle pass through the articulated elements cross arrangement, the upper end of pincers handle one and pincers handle two all is equipped with the binding clip, threaded connection has hollow guide sleeve on the binding clip, set up on the binding clip with hollow guide sleeve assorted spiral shell, also have foretell problem. Therefore, there is a need for a forceps-type orthopedic reduction tool that can meet the requirements of a specific anatomical bone location or a relatively narrow surgical space.

SUMMERY OF THE UTILITY MODEL

1. The technical problem to be solved is as follows:

aiming at the technical problem, the utility model provides a medical half-pipe fracture reduction fixator, which adopts asymmetric forceps heads to adapt to a narrower operation area; a hollow guide sleeve for placing a Kirschner wire or a bone round needle is arranged on one straight forceps head to meet special bone anatomy.

2. The technical scheme is as follows:

the utility model provides a medical half pipe fracture reduction fixer which characterized in that: comprises a left forceps handle, a right forceps handle and a left forceps head; the left tong head is arc-shaped and the arc is bent inwards; the right forceps head is straight and longer than the right forceps head in extension length; and a hollow sleeve in the same extending direction as the right forceps head is arranged on the outer side of the right forceps head.

Further, a bolt is arranged between the left clamp handle and the right clamp handle; the left end of the bolt is fixed on the inner side of the left clamp handle, and the right end of the bolt is sleeved with an adjusting nut after penetrating through the right clamp handle;

furthermore, the left and right clamp handles comprise extension sleeve handles.

Furthermore, the left and right forceps handles are connected with the left and right forceps heads through a hinge structure.

Furthermore, finger ring sleeves are arranged at the bottoms of the left and right clamp handles.

3. Has the advantages that:

(1) one of the forceps heads is arc-shaped, and the other is strip-shaped, so that the operation space required by the forceps heads is effectively reduced.

(2) The sleeve for placing the Kirschner wire or the bone round needle is arranged at the position of the strip-shaped forceps head, the extending direction of the sleeve is consistent with the extending direction of the forceps head, so that the sleeve is beneficial to adapting to a narrow operation space or an operation scene with unavoidable important nerve vessels in an insertion channel of the reduction forceps, and the Kirschner wire or the bone round needle passes through sclerotin along the hollow sleeve in the scene to achieve a disposable fixing effect. Not only can meet the resetting requirement of the operation, but also can avoid the injury of repeated fixation to sclerotin.

Drawings

FIG. 1 is a schematic structural diagram of the present invention.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in the attached figure 1, the medical half-pipe fracture reduction fixator is characterized in that: comprises a left forceps handle 2, a right forceps head 1 and a left forceps handle; the left tong head is arc-shaped and the arc is bent inwards; the right forceps head is straight and longer than the right forceps head in extension length; and a hollow sleeve 3 which has the same extension direction with the right forceps head is arranged on the outer side of the right forceps head.

Further, a bolt 4 is arranged between the left clamp handle and the right clamp handle; the left end of the bolt is fixed on the inner side of the left clamp handle, the middle of the bolt penetrates through the right clamp handle, and the right end of the bolt is sleeved with an adjusting nut 5.

Further, the left and right forceps handles comprise extension sleeve handles 6.

Furthermore, the left and right handles are connected with the left and right heads through a hinge structure 7.

Further, finger ring sleeves 8 are arranged at the bottoms of the left and right clamp handles.

The specific embodiment is as follows:

when the fracture reduction fixator is used, the length of the extension sleeve handle is set, the length of the forceps handle can be adjusted according to needs, and then the fixation is carried out through the fastening bolt, so that the application range of the fracture reduction fixator is enlarged; through the arrangement of the bolt, after the bone is reset, the adjusting nut is screwed at the handle part of the forceps, so that the reset of the bone block can be maintained, and an operator can vacate two hands for subsequent operation; through setting up the cavity sleeve and combining with rectangular form binding clip, can make gram formula needle pass through the sclerotin along hollow guide sleeve, reach disposable fixed best effect, both can satisfy the needs operation demand that resets, also can fix for gram formula needle by orientation, avoid fixing the damage to the sclerotin repeatedly many times, improved the accuracy, reduced patient's misery.

Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the utility model as defined by the appended claims.
