Description

Orthopedic spinal surgery tissue opening forceps

Technical Field

The invention relates to the field of medical instruments, in particular to a pair of orthopedic spine surgery tissue opening forceps.

Background

The spinal diseases are that sclerotin, intervertebral disc, ligament and muscle of the spine are diseased, and then the spinal cord, spinal nerves, blood vessels and vegetative nerves are pressed and pulled to stimulate, thereby causing complex and various symptoms. The common diseases include cervical spondylosis and lumbar spondylosis. The main symptoms are: failure to stand upright, headache, vertigo, blurred vision, memory loss, soreness of the neck and shoulders, poor appetite, regurgitation, vomiting, weakness of lower limbs, and paralysis in severe cases.

Two methods, namely surgical treatment and non-surgical treatment, are mainly adopted for clinically treating the spinal diseases. As shown in fig. 1, cut open patient's skin and expose the backbone, then adopt to strut the pincers to strut certain opening to the tissue on backbone both sides and make things convenient for the doctor to perform the operation, among the prior art, because backbone operation time is long, need keep the strut of longer time to strutting pincers, because the operation in-process can not make to strut pincers easily and rock: if take place to rock and make the opening reduce and influence doctor's operation sight promptly to increase the risk of operation failure, then probably arouse patient's backbone department blood to surge if the opening grow, thereby lead to the operation failure, among the prior art moreover, prop the head for fixing in propping open pincers tip department, prop the first kind of singleness of opening, and because there is the difference in the state of an illness of every patient's backbone operation, so will be fit for in time changing propping open first kind.

Disclosure of Invention

The invention aims to provide a pair of tissue spreading forceps for an orthopedic spine operation to solve the problems in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme:

the utility model provides an orthopedics spinal surgery tissue struts pincers, includes first pincers handle, second pincers handle and opens a mouthful location portion, first pincers handle, second pincers handle are connected through the round pin axle is articulated, and the extension length is reserved to the one end of this round pin axle, open a mouthful location portion fixes and reserves the tip of stretching out at the round pin axle, the spliced pole is all installed to the head end of first pincers handle, second pincers handle, the cover is equipped with the connecting rod on the spliced pole, and the other end and the cooperation of opening a mouthful location portion of this connecting rod are connected, and still install the grab handle on being close to the connecting rod of opening a mouthful location portion, the afterbody of first pincers handle, second pincers handle is installed and is propped first fixed part, should prop first fixed part of opening and.

Further, open a mouthful location portion includes fixed link, ring cover and locking bolt I, wherein: the middle part of the fixed connecting rod is fixed on the end part of the pin shaft which is reserved to extend, the two groups of the ring sleeves are respectively arranged on the fixed connecting rods on the two sides of the pin shaft and are in movable fit with the fixed connecting rods, the other ends of the connecting rods are fixedly connected with the ring sleeves, and the locking bolts I penetrate through the ring sleeves and are in fit connection with the fixed connecting rods.

Further, open a mouthful location portion includes pole I, pole II and locking bolt II, wherein: the end of pole I is fixed on the tip that the round pin axle was reserved and is stretched out, and pole I has seted up the blind hole, II poles are through inserting blind hole and I clearance fit of pole, II locking bolts run through in I to the blind hole of pole with II locking cooperation of pole, and pole I, II correspond respectively and are fixed with the other end of connecting rod.

Furthermore, the supporting head is a bent head or a hook head, and the bent head or the hook head is provided with an integrated plug pin.

Furthermore, a groove body used for inserting the inserting pin is formed in the fixing part of the supporting head.

Further, install on the first fixed part of strutting and strut first fixed part, should strut first fixed part and include fixed pin and fixed band, wherein: the fixed pin runs through to be installed on being close to the first fixed part that struts of cell body opening part, the one end at the fixed pin is fixed to the one end of fixed band, and the other end of fixed band is through the fixed orifices on it and the fixed cooperation of the other end of fixed pin.

Compared with the prior art, the invention has the beneficial effects that: open mouthful location portion can avoid the doctor to hold two pincers handles of strutting the pincers for a long time, can keep strutting of longer time to strutting the pincers, can not make the pincers of strutting easily in the operation process and rock: the opening is reduced due to shaking, so that the operation sight of a doctor is not influenced, the risk of operation failure is increased, or the blood surge at the spine of a patient is possibly caused due to the enlarged opening, so that the operation failure is caused. Because the conditions of each patient are different, if the tissue of the patient dissects the opening is loose and slides, the opening can be propped up by the two hook-shaped heads, the tissue at the opening is prevented from sliding off from the hook-shaped heads, so that the opening is closed, and if the capillary vessels in the tissue of the patient dissects the opening are dense, the two bent heads can prevent the capillary vessels from being scratched, so that the blood at the vertebral column in the opening is prevented from being too much, and the operation is influenced; the inserting pin can be inserted into and pulled out from the groove body, so the curved head and the hook-shaped head can be conveniently replaced, and the replaced curved head or the replaced hook-shaped head can be fixed on the distraction head fixing part through the fixing band.
