Description

Cervical intervertebral disk is cut the suction therapeutic instrument

This utility model relates to the operating theater instruments of medicine and hygiene fields, particularly is applicable to the cutting of human body sub-dermal soft tissue and the operating theater instruments that the excision thing is discharged.

Diseases such as prolapse of cervical intervertebral disc are frequently-occurring disease, the commonly encountered diseases of the particularly middle-aged and elderly people of human body, bring great misery to the patient.The generally acknowledged effective ways of such disease of treatment are operative treatments at present.Promptly cut the muscular tissue of disease sites with scalpel, removal lesion tissue then, because of cervical vertebra peripheral nerve blood vessel more, during operation, the patient faces danger such as surgical injury spinal cord, and surgical wound surface is big, postoperative healing is slow, so patient accepts when performing the operation and the postoperative misery is bigger.

It is little that the purpose of this utility model just provides a kind of surgical wound surface, and patient's misery is little, and the cervical intervertebral disk of wound site capable of washing and eliminating excision thing is cut the suction therapeutic instrument.

In order to reach the purpose of this utility model, adopt the method for puncture that narrow and small cutter are probeed into diseased region from the working column inner chamber, removal lesion tissue drives sterilised liq flushing cutting part and sucking-off excision thing with negative pressure then.Its technical scheme is: by power section, power passes part, outer cutter, and interior cutter, working column, head is formed.One end of its motivation transfer motion part and power section screws after pegging graft, and screws after the interior cutter in the other end and the head are pegged graft.Power section is a safe motor, and motivation transfer motion part is waited by the flat axle of flexible axle to be formed, and handle and head tail end are fixedly connected.Outer cutter rear end and head front end are closely pegged graft and are screwed, the front end external diameter of interior cutter coincide with the front inner diameter of outer cutter, the cutter head external diameter should be slightly less than outer cutter head internal diameter promptly, and interior cutter front end is shaped as unicuspid shape, two sharp fork-shapeds, middle concave etc.Working column and head can fuse and also can use separately, and the working column inner chamber should make outer cutter insert.The cutter head that should guarantee outer cutter leans out outside working column, should leave the slit between working column inner chamber and the outer cutting knife body, liquid is flow through from this slit, and can flow out from the sleeve pipe front end, can adjust the distance of circumscribed cutter head and working column mouth by handle, outer cutter rear end and working column should airtight the connections; Make that water is unlikely to flow out from its rear end.The turnover water nozzle of whole therapeutic instrument is located at respectively on working column and the head, water inlet tap communicates with the working column inner chamber, faucet communicates at the external negative pressure source of faucet with interior cutter inner chamber, makes between the turnover water nozzle and sets up a micro channel by subcutaneous cutting part.Be sterilised liq from water inlet tap through working column and outside slit between the cutter, because the effect of negative pressure, make liquid flow out to diseased region from the working column front end, utilize the impact of liquid, the pathological changes soft tissue that downcuts is entered interior cutter inner chamber from outer cutter head with interior cutter head and liquid, discharge from faucet then, and reach the purpose of cleaning wound site simultaneously.

According to above technical scheme, outlet on the head should be connect negative pressure source during use, the reason of on the water inlet on the working column, delivering a child saline container, selected point of puncture uses puncture needle to enter pathological interspinal Pan Chu through cervical region under the X ray guiding, re-use guiding convergent divergent channel and working column the sleeve pipe front end is placed nearly diseased region, then cutter are inserted diseased region through the working column inner chamber, start motor, give interior cutter with flexible axle with transmission of power, the cutter rotation forms shearing force with the forward recess of outer cutter in making, excision pathological changes soft tissue, and make the excision thing with discharging from the outlet on the head through interior cutter inner chamber from the effusive normal saline of working column mouth.Art finishes extracts cutting tool and working column.

Owing to motor and operating theater instruments split, alleviated the weight of operating theater instruments, make and cure the thing personnel operation conveniently, this utility model is owing to adopt the rotational shear mode, and shearing force is strong, and apparatus is shaken gently during operation, is convenient to accurate assurance.

Below in conjunction with accompanying drawing a kind of embodiment of the present utility model is described:

Accompanying drawing one is this utility model working column body and head separated structures sketch map;

Accompanying drawing two is the A-A amplification view of figure one;

Accompanying drawing three is the B-B cutaway view of figure two;

Accompanying drawing four is interior cutter head sketch map, and wherein (a) is two sharp forked type cutter heads; (b) be unicuspid shape cutter head; (c) be the drop centre type cutter head.

1 is outer cutting knife body in the accompanying drawings, the 2nd, outer cutter head, the 3rd, outer cutter fixture, the 4th, outer cutter seat, the 5th, head body, the 6th, the fixed screw between head 5 and the tool rest 4, the 7th, the sealing ring between head 5 and the tool rest 4, the 8th, the breathing sealing gasket, the 9th, the inscribe cutter bod, 10 is interior cutter head (inlet opening), 11 is the apopore of inscribe cutter bod 9,12 is the faucet on the head body 5, and 13 is the inward turning rotating shaft, and 14 is the internal rotation axle sleeve, 15 is flat axle, 16 is flexible axle, and 17 is this utility model handle, the 18th, and working column, the 19th, the working column seat, the 20th, water inlet tap, the 21st, the sealing gasket between casing seat 19 and the outer cutting knife body 1, the 22nd, the slit between sleeve pipe 18 and the outer cutting knife body 1.

This therapeutic instrument, by power section (safe motor of band protector), motivation transfer motion part (comprising inward turning rotating shaft 13, flat axle 15, flexible axle 16 etc.), outer cutting knife body 1, inscribe cutter bod 9, head 5, working column 18 are formed.The flexible axle 16 of motivation transfer motion part one end connects with safe motor, and the inward turning rotating shaft 13 and inscribe cutter bod 9 ends of the other end are fixedly connected.At inscribe cutter bod 9 overcoat outer cutting knife bodies 1, the rear end of cutter hub 1 and head 5 front ends are closely pegged graft.On working column seat 19, be provided with liquid influent mouth 20 and communicate, on head 5, establish liquid faucet 12 and communicate through the inner chamber of apopore 11 with inscribe cutter bod 9 with the inner chamber of working column 18.Cut outside between tool rest 4 and the head 5 and be provided with O-ring seal 7, on head 5, have the screw 6 of cutter seat 4 outside fixing; Packing ring 8 is used to compress and fixed seal ring 7.The internal diameter of interior cutter head 10 external diameters and outer cutting knife body head 2 coincide (microgap is arranged).Interior cutter head 10 be shaped as unicuspid shape, two sharp fork-shaped, middle concave, select to use when being convenient to excise different organizing.

During use, normal saline enters cutting knife from the slit 22 that water inlet tap 20 enters between working column 18 internal chamber walls and the outer cutting knife body 1, from outer cutter head 2 with being entered the inner chamber of inscribe cutter bod 9 from cutter head 2 and 10 by the subcutaneous pathological changes soft tissue under the 10 rotation excisions of interior cutter head, through apopore 11 then faucet 12 by the negative pressure source sucking-off.Have the function of not cutting skin and flesh and subcutaneous pathological tissues being downcut and getting rid of, and operation technique is easy, patient's misery is little.
