Description

Olecranal fracture reduction forceps

Technical field

The utility model relates to medical instruments fields, more particularly to a kind of olecranal fracture reduction forceps.

Background technique

Fixed operation method is in olecranal fracture Pin fixation, under brachial plexus anesthesial, takes vertical on rear side of elbow Shape notch, is about 8~10cm.Skin subcutaneous tissue is cut, side (or ulnar side) is scratched with olecroanon point and cuts elbow posterior joint capsule, edge Anconeus is opened in ulna back lateral incision, and subperiosteum removing appears fracture end, eliminates the outmoded hematocele between fracture end and the fiber of adhesion Property tissue, elbow joint is stretched under direct-view, intra-articular fracture block reset is fixed temporarily with towel clamp towel forceps, olecranon tip later side Fixed 2 points are placed in Kirschner wire with electric drill respectively, and direction and the ulna longitudinal axis are 10 ° or so angled, pierce and are fixed on dish-shaped bone block On main sclerite, ulna distal forward cortical bone is penetrated.Then by 2~3cm of fracture end distal end, inward-outward direction bores a hole, steel Silk passes through rear 8 word and Kirschner wire fastens, and steel wire knot embedment ulna scratches side, finally cuts short Kirschner wire, tail bending that let the acupuncture needle remain at a certain point.Stretch elbow joint Normal range (NR) is fully achieved, loose tourniquet thoroughly stops blooding, layer-by-layer suture wound.

When doing olecranal fracture Pin fixation internal fixation operation, fracture end it is accurate reset be operation at The key of function.After fracture end accurately resets, could accurately establish two Kirschner wires in steel wire tunnel and accurate positionin enters needle Point.

It is further used as the improvement of technical solutions of the utility model, left clamp handle is equipped with bolt, and right clamp handle is equipped with and lock The mutually matched lockhole of item.

It is further used as the improvement of technical solutions of the utility model, the included angle of pawl head and pawl body is less than 90 °.

The utility model has the beneficial effects that this olecranal fracture reduction forceps, the end of the fracture end of olecroanon is used Chela in left clamp handle clasps, and the chela in right clamp handle catches on the two sides of ulna, so that a stable force structure is constituted, By adjusting the angle between left clamp handle and right clamp handle, the fracture end of olecroanon is accurately resetted, the fixed operation after being Be ready, the angle between left clamp handle and right clamp handle can the body make-up of different patients be adjusted, be suitable for each age The patient of section, reaches more accurate reset effect.

Detailed description of the invention

The utility model is described in further detail with reference to the accompanying drawing:

Fig. 1 is the overall structure diagram of the utility model embodiment；

Fig. 2 is the operation chart of the utility model embodiment.

Specific embodiment

Referring to Fig.1, Fig. 2, the utility model is olecranal fracture reduction forceps, including the left clamp handle 1 being hinged and the right side Clamp handle 2, left clamp handle 1 and right clamp handle 2 include handheld terminal and pinching end, and the pinching end of left clamp handle 1 and right clamp handle 2 is equipped with several Chela 3, chela 3 include pawl head 31 and pawl body 32, and left clamp handle 1 and the opposite side of right clamp handle 2 are clamping face, are located at left clamp handle 1 On chela 3 pawl head 31 towards the clamping face of right clamp handle 2, the chela 3 in right clamp handle 2 shares two, two pincers in right clamp handle 2 Pawl 3 is set to the clamping face two sides of right clamp handle 2, and the pawl head 31 of two chelas 3 in right clamp handle 2 is opposite.

This olecranal fracture reduction forceps clasps chela 3 of the end of the fracture end of olecroanon in left clamp handle 1, Chela 3 in right clamp handle 2 catches on the two sides of ulna, to constitute a stable force structure, effectively overcomes tradition Occur resetting difficult situation when reseting fracture end interim using towel clamp towel forceps in operation, by adjusting between left clamp handle 1 and right clamp handle 2 Angle, the fracture end of olecroanon is accurately resetted, the fixed operation after being is ready, left clamp handle 1 and right clamp handle 2 it Between angle can the body make-up of different patients be adjusted, suitable for the patient of all age group, reach more accurate multiple Position effect.

As the utility model preferred embodiment, the end of right clamp handle 2 is equipped with axis and is parallel to each other with its clamping face Shaft, shaft and right clamp handle 2 be rotatablely connected, and two chelas 3 in right clamp handle 2 are separately fixed at the both ends of shaft.It is right Chela 3 in clamp handle 2 is rotated by shaft around right clamp handle 2, can be revolved the chela 3 in right clamp handle 2 according to the case where each patient Suitable position is gone to, firmly to catch on the side of ulna.

As the utility model preferred embodiment, pawl head 31 is equipped with the through-hole 311 at perforation 31 both ends of pawl head.Specifically , the through-hole 311 on chela 3 in left clamp handle 1 can be passed through with for Kirschner wire, and for the merging of kirschner nail, and piercing will be dish-shaped Bone block is fixed on main sclerite, and the through-hole 311 on two chelas 3 in right clamp handle 2 drills simultaneously on ulna for Kirschner wire Bone channel is established, steel wire can be then worn in bone channel, finally one will be formed with Kirschner wire after steel wire " 8 " winding and opens Power band fixed system.

Before steel wire and Kirschner wire form tension band fixation system, it is necessary to (the distance fracture on the ulna spine of proximal ulna Distally at 2~3cm), inward-outward direction bores a hole to establish the bone channel of steel wire, however in clinical practice operation, steel wire bone Property Path Setup superiority and inferiority often determined by the clinical manipulation experience of operative doctor, the design of this reduction forceps be effectively shortened just The learning curve of scholar, so that steel wire channel is more accurately established.

As the utility model preferred embodiment, the chela 3 in left clamp handle 1 shares two, and two chelas 3 are V-shaped Be symmetrically disposed on the two sides of the clamping face of left clamp handle 1 so that chela 3 catch on it is stronger when ulna.

As the utility model preferred embodiment, left clamp handle 1 is equipped with bolt, and right clamp handle 2 is equipped with and bolt phase The cooperation of the lockhole mutually cooperated, bolt and lock enables the angle between left clamp handle 1 and right clamp handle 2 accurately to control.

As the utility model preferred embodiment, the included angle of pawl head 31 and pawl body 32 forms one less than 90 ° Stable grapple structure so that chela 3 catch on it is stronger when ulna.

The utility model is hooked fracture end tightly by the way of chela 3 is arranged on reduction forceps, then adjusts left clamp handle 1 and the right side The angle of clamp handle 2 enables fracture end parking position accuracy.It is logical on the chela 3 in left clamp handle 1 since chela 3 is equipped with through-hole 311 Hole 311 can be used as the placed channel of merging Kirschner wire, play the role of auxiliary positioning, the positioning of Kirschner wire is more convenient, and energy Effectively shorten operating time；And the through-hole 311 on the chela 3 in right clamp handle 2 can play auxiliary Kirschner wire and establish bone channel Effect, so that the foundation in bone channel more accurate quick, improves the accuracy that steel wire is worn and the efficiency worn.

The design concept of the utility model is to advanced optimize olecranal fracture Pin fixation internal fixation Middle process enables reset accurately to carry out simultaneously with fixation, the learning curve of beginner is effectively shortened, so that this basis Modus operandi can allow orthopaedics primary doctor faster, better grasp.

Certainly, the invention is not limited to above embodiment, and those skilled in the art are without prejudice to originally Equivalent deformation or replacement can be also made under the premise of utility model spirit, these equivalent variation or replacement are all contained in the application In claim limited range.
