Abstract

The invention relates to a fracture reduction holding clamp comprising two clamping bodies and two bone clamping needles, wherein the two clamping bodies are respectively clamped on bone bodies positioned on two fracture broken ends through the bone clamping needles and can carry out manipulative reduction instead of bone clamping forceps. After reduction, adjacent clamp heads are connected by using a tension spring, and adjacent clamp holders are connected by using a horizontal plate so that the two clamping bodies are formed into an integer so as to form a geometrical relative invariant system with the fracture broken ends. The fracture reduction holding clamp masterly applies the lever action to the reduction and the fixation of fractures by using a clamp and a torsional spring, thereby reducing the volume and the weight of a device and enlarging the application range; the invention can ensure the functional reduction, relieve the pains of patients and enable the fixation to be stable and elastic by using the torsional spring and the tension spring, thereby retaining the fine motion of the fracture broken ends and enabling the fracture broken ends to obtain physiological stress stimulus; the invention shortens the creeping distances of new bone cells through accurate reduction and stable fixation without surgeries, thereby preventing the iatrogenic injury; and in addition, the invention does not violate the blood supply and the blood circulation, thereby protecting the bone hematomas, the periosteum and the biological environment of fracture healing and accelerating the progress of the fracture healing.

Description

Reduction of the fracture fixation clamp

[technical field] the invention belongs to medical domain, and fixed apparatus is used to reset when particularly relating to surgery orthopaedics therapy fracture.

The fractures method that [background technology] is traditional is a manual reduction, small splints fixation.Its method is easy, and expense is cheap, and the swollen and periosteum of protection flesh and blood does not destroy blood and follows, and does not have wound again.But because of between clamping plate and the bone across skin, fat, muscle, soft tissue, can not effectively control the bone stump that takes place because of myotility effect and fracture far-end rotation and be shifted.The internal fixation of doctor trained in Western medicine can reach anatomical reduction, and fixing strong, stable, and is effective for the fractures at positions such as osteoarthrosis, pelvis, spinal column.But steel plate has occlusion effect, and the blood that operation influences bone stump follows, and causes the cortical bone attenuation, causes the danger of disunion and refracture to increase.The advantage of the comprehensive integrative therapy fracture of " Meng and the frame " of professor's Meng He invention preferably resolves the problems referred to above.99246159.6 number formerly patent is near the function of the Meng and frame, the blemish in an otherwise perfect thing volume is big, and the scope of application is little.

[summary of the invention] the object of the present invention is to provide a kind of advantage and volume with the Meng and frame little, in light weight, be applicable to non-comminuted long diaphysis, clavicle, rib, phalanges and near the apparatus of the fractures at osteoarthrosis position, promptly a kind of reduction of the fracture fixation clamp.

The present invention includes two clamps and the splenial bone pin 1 more than four or four, it is characterized in that: each chuck (comprising two slit bamboo or chopped woods up and down) has two or more pin holes that spiral is arranged 2, to hold splenial bone pin 1; Two clamps are clipped in respectively by splenial bone pin 1 on the diaphysis of two fracture sites, and adjacent chuck connects with horizontal plate 8 with extension spring 3 connections, adjacent clamp holder, so that two clamps form one, constitute the relative invariable system of geometry with fracture site.

Common clip in the similar daily life of clamp divides two slit bamboo or chopped woods up and down, and preceding be chuck, and the back be a clamp holder, and there is support chip middle both sides, pivot by support chip up and down two slit bamboo or chopped woods be connected as a single entity, clamp holder about the torsion spring support is installed on the pivot; Clamp is made with metals such as rustless steel or nonmetallic materials, and the rigidity of clamp and the elastic force of torsion spring should be able to clamp diaphysis effectively, can be sustained by diaphysis again.

The needle point form of splenial bone pin 1 can be smooth syringe needle, can prick to compact bone, also can be to have to eat the syringe needle that murices revolves, but the precession compact bone; There is spiral at the needle handle position, but precession pin hole 2, and reuse nut 5 is fixed.

Have the fixing hole that spiral is arranged 6 more than two on every slit bamboo or chopped wood clamp holder, be rotary with trip bolt 9 on it, in order to fixing handle 7 or the horizontal plate 8 of prolonging; Use prolongation handle 7 can overcome the powerful elastic force of torsion spring, be convenient to free-hand operation.

Extension spring 3 connects two chucks by the extension spring post on the chuck 4, fracture site is closely contacted and has the fine motion phenomenon.

For the thinner fracture of treatment, can be deformed into a clamp to two clamps, chuck is deformed into the curved splenial bone pin 1 more than four or four, omits extension spring 3 and horizontal plate 8, has dwindled volume.

During with reduction of the fracture fixation clamp treatment long bone shaft fracture, assist fixingly to hindering limb, fixingly not be subjected to big outside destroy, keep far and near hold static relatively of fracture with what guarantee bone stump with plintlet.Both guaranteed fixing strong stablizing, and made volume of the present invention enough little again.

Reduction of the fracture fixation clamp can be made into volume difference, several models that splenial bone pin 1 length is different, with the fracture diaphysis that adapts to different-diameter and hinder limb.

The present invention is creationary cleverly to be applied to resetting of fracture and fixing to leverage with the clip torsion spring, saves support bodys such as support bar, semi-ring, has reduced volume and weight, has enlarged range of application; Make to reset accurately and simple to operately, reduce patient's misery; Reset accurately and the stable area of new bone cell distance of creeping of fixedly having dwindled, accelerated the progress of healing.

Beneficial effect of the present invention: fractures has three basic principles, i.e. dissection or functional reduction, keep reset the back position until the healing and functional exercise.Effect of the present invention meets mentioned above principle fully, and the one, can guarantee functional reduction, be close in anatomical reduction.The 2nd, fixing-stable, clamp, clamping plate constitute relative invariable system how much with the far and near end of fracture.The 3rd, owing to fix, the clamp volume is little helps functional exercise.The present invention has also possessed three key factors of effective union of fracture, and promptly clamp is used in combination with clamping plate and has constituted held stationary; Make with torsion spring and extension spring to be fixed with elasticity, kept the fine motion of bone stump, making it obtain physiological stress stimulates, and makes the callus formation reaction be able to repetition and continuity, accelerates healing; Owing to need not have an operation, soft tissue damage is minimum, does not destroy blood fortune, blood follows, and has protected that flesh and blood is swollen, the biological environment of periosteum and union of fracture.
