With reference to the accompanying drawings shown in the 1-16, the complete surgical instruments for removal of percutaneous mdrrow nucleus pulposus of invention by three pieces of nucleus angiography needles, 3 pieces of outer casing needles, Ke Shi draw point, sword shape dermatotome, urceolus, tube core, inner tube trephine, feeler lever, snail hook biopsy forceps, pliability biopsy forceps, guider, special pin device, sharp tweezer, cup, cotton applicator totally 16 kinds of 20 instruments form.These 16 kinds of 20 instruments have constituted the medical apparatus and instruments that the treatment prolapse of lumbar intervertebral disc adapts to.Have 11 kinds to be the product of the U.S. or Japan and other countries public offering in these 16 kinds of 20 instruments, but it does not satisfy the needs of doing removal of percutaneous mdrrow nucleus pulposus.My basis clinical experience for many years.Trial production repeatedly, New Development is understood three kinds of instruments such as sword shape dermatotome, feeler lever, snail hook such as Fig. 4, Fig. 8, shown in Figure 9.Two kinds of instruments such as pliability biopsy forceps, pliers guider such as Figure 11, shown in Figure 12 have been invented in improvement.Like this, the medical instrument of the treatment prolapse of lumbar intervertebral disc of existing public offering in the world and use has been carried out replenishing and perfect.Bring convenience to the medical personnel, for therapist palliates the agonizing sufferings.
The sword shape dermatotome of invention, whole as sword shape as shown in Figure 4, have through hole on the axis of cutter with Ke Shi draw point coupling.This cutter is cut skin and is used, during use, sword shape dermatotome is enclosed within on the Ke Shi draw point, thrust along the Ke Shi draw point, cut skin, dark sarolemma,, then sword shape dermatotome is taken off with the rupture of membranes sense that feel has twice resistance as can be known and stings, promptly cutting one on the skin is the 0.5cm otch at center with the Ke Shi draw point, on the dark sarolemma same otch is arranged also.
The feeler lever of invention, as shown in Figure 8, feeler lever is the stainless steel strip of a diameter 2mm, be carved with length mark on the steel bar, total length equates with inner tube trephine, one end is provided with annular hand grip, its using method is: finish inner tube trephine drilling fibrous ring in operation process after, feeler lever is stretched into from the inner tube trephine centre bore, when feeling resistance, watch inner tube trephine to remain the length of feeler lever outward, equate (1.7cm) as length difference with inner tube trephine, urceolus, the fibrous ring piece of tissue of filling capacity in the inner tube trephine then is described, oneself finishes the operation of drilling fibrous ring.As when watching inner tube trephine to remain feeler lever curtailment (1.7cm) at home and abroad, illustrating does not have the fibrous ring of capacity piece of tissue in the inner tube trephine.
The snail hook of invention, as shown in Figure 9, snail hook end parts such as helical form, external diameter is 0.4cm, and internal diameter is 0.2cm, and tooth pitch is 0.6cm, the spiral revolution was 1.5 weeks, length is 1.0cm, and the shank diameter is 0.1cm, and length is 14cm, hook end and shank total length equate with inner tube trephine, handle portion length 4.0cm, moment brachium 1.5cm, moving sleeve internal diameter 1.6mm, external diameter 2.0mm, the supporting use of this snail hook and inner tube trephine when inner tube trephine drilling fibrous ring operation is finished, and proves the success of drilling through using feeler lever to detect, pull out feeler lever, snail hook is stretched into from the inner tube trephine centre bore, after running into the resistance that the fibrous ring piece of tissue stops, the rocking-turn spiral neck of hook along clockwise direction, and inwardly compress, can be with fibrous tissue piece bolt-lock in inner tube trephine, then with the spiral shell hook, inner tube trephine, the fibrous tissue piece is extracted from urceolus together, shift out external, can once finish the boring on the fibrous ring smoothly, this is simple and quick, accurately and reliably.
The pliability biopsy forceps of invention, as shown in figure 11, these pincers are to improve invention on the basis of biopsy forceps (Figure 10), its main points are to set up the spring 2 that a segment length is 30-40mm between the claw beam 1 of existing biopsy forceps and jaw 3.
The guider of invention as shown in figure 12.Constitute by guide post 4, guide sub 6, pull bar 5, spring 7, Spring Card 8, the bottom of guide post 4 and guide sub 6 hinge connection, spring 7 is contained in the rearward end of guide post 4, Spring Card 8 is contained on the guide post 4 to withstand spring 7, pull bar 5 one ends are connected with Spring Card 8, and the other end is connected with guide sub 6.
Pliability biopsy forceps and guider coupling are used.During use guider is stretched into from urceolus, go deep into length 15cm, see through the most advanced and sophisticated 2.2cm of urceolus, in guider, insert the pliability biopsy forceps this moment again, 1.0cm can be stretched out from side opening in the pliers tip, crooked 30 ° of pliability biopsy forcepss picked-up guider side nucleus pulposus, as Spring Card 8 is pulled back, and be stuck on the guide post 4, the side guider gos deep into 3mm forward, and guide end is to bent 30 ° of perforate lateral bending, camber addition with the guiding side opening, can make the total camber of spring lever portion of pliability biopsy forceps reach 50-60 °, the nucleus pulposus of pliability biopsy forceps picked-up guider side, working range promptly enlarges.During EO, need first pull-off spring card 8, take out the pliability biopsy forceps, just can go out to get guider then.
The percutaneous Nuclectomy operation rig of invention, great variety of goods, easy to use, can improve the operation quality, shorten operating time, alleviate patient's misery.
