Abstract
The utility model relates to a lumbar intervertebral disc cutting and suction therapy apparatus. One end of a flexible shaft assembly is connected with the power shaft of a safety motor and the other end of the flexible is inserted with the tail end of an inner cutting knife assembly in a machine head. The rear end of an outer cutting knife assembly is tightly inserted with the front end of the machine head, the handle of the outer cutting knife assembly is threaded and coupled with the tail end of the machine head, and in addition, the inner part of the outer cutting knife assembly is sheathed with an inner cutting knife. The device is characterized in light weight, little vibration, convenient operation, and high cutting efficiency, with serious complications avoided.
Description
This utility model relates to the operating theater instruments of medicine and hygiene fields, particularly the lumbar intervertebral disc operation apparatus.
It is a kind of common disease that lumbar intervertebral disc is deviate from, and brings great misery to the patient.Effective Therapeutic Method of generally acknowledging is an operative treatment at present, promptly cuts the muscular tissue of disease sites with scalpel, and is neural because of gathering around the lumbar vertebra then with excision of the lesion, makes the patient face the unexpected dangerous of surgical injury nerve and general anesthesia.General postoperative complication accounts for 14～20%, and postoperative need lie in bed one month, the expense height, and patient is painful big.Chinese patent [patent No.: 902192736] discloses a kind of prolapse of intervertebral disc therapeutic instrument, it is a kind of novel percutaneous lumbar intervertebral disc ablation technique, this technology is utilized the new-type guidance system of a cover, put into intervertebral space, through these cutter of sending into the prolapse of intervertebral disc therapeutic instrument vertebral pulp cutting is combined together with sucking-off again, having shortened operating time does not have severe complication, and effective percentage is up to 98%.But this apparatus is defectiveness also: 1, motor is installed on the operating theater instruments, operating theater instruments weight is big, it is heavy to compare; 2, interior cutter impact type cutting, the apparatus shake is difficult for holding.
The purpose of this utility model is to overcome above-mentioned operating theater instruments defective, provide a kind of in light weight easy to operate, cut and inhale the higher therapeutic instrument of efficient.
Technical solution of the present utility model is: lumbar intervertebral disc is cut the suction therapeutic instrument, comprises power section, head, outer cutter assembly, interior cutter assembly.Interior cutter assembly tail end in the flexible axle assembly other end that one end connects with the safe motor line shaft and the head is pegged graft, and handle and head tail end are fixedly connected.The outer cutter assembly rear end and the head front end of cutter are closely pegged graft in the interior cover.The front end external diameter of interior cutter coincide with the front inner diameter of outer cutter, and the anterior undergauge of interior cutter place leaves the backwater hole that communicates with inner chamber.Interior cutter front end is shaped as unicuspid shape, two sharp fork-shaped, middle concave.
According to technique scheme, earlier the outlet on the head assembly is connect negative pressure source, the water inlet reason saline container of delivering a child during use.Selected point of puncture under the guiding of X line, use puncture needle earlier in the back muscle group enters the pathological interspinal dish, re-use the guiding convergent divergent channel, then cutter are inserted diseased region through convergent divergent channel, start motor this moment, the flexible axle assembly is given interior cutter assembly with transmission of power, and interior cutter rotation forms shearing force with the forward recess of outer cutter, and resection organization discharges from the outlet on the head with normal saline through interior cutter inner chamber.Art finishes extracts puncture needle and guides the convergent divergent channel wrapping to get final product.
Owing to motor and operating theater instruments split, alleviated the weight of operating theater instruments, easy to operate, adopt the rotational shear mode, shearing force is strong, and the operating theater instruments shake is light, is convenient to accurate assurance.
Accompanying drawing 1 is this utility model structural representation;
Accompanying drawing 2 is a cutter sketch map in this utility model.
In conjunction with the accompanying drawings, a kind of embodiment of the present utility model is described.
Lumbar intervertebral disc is cut the suction therapeutic instrument, comprises power section, head 15, outer cutter assembly 2, interior cutter assembly 12.Flexible axle assembly 11 other ends that one end connects with safe motor (safe voltage, band protector) line shaft and interior cutter assembly 12 tail ends in the head 15 are pegged graft handle 10 and head 15 tail end thread connection; Outer cutter assembly 2 rear ends and head 15 front ends of cutter 17 are closely pegged graft in the interior cover.The dynamic inserted sheet 9 of flexible axle assembly 11 front ends cooperates with the socket 8 of interior cutter assembly 12; Having normal saline to import and export 5 above the head 15 communicates with the water inlet 4 of outer cutter assembly 2, there is outlet 13 to communicate below the head 15 with the outlet 14 of interior cutter assembly 12, normal saline enters water inlet 4 from water inlet 5 and enters cutting knife through the gap of interior cutting assembly 12 and outer cutter assembly 2, then the inner chamber that enters interior cutter assembly 12 with resection organization through outlet 14, outlet 13 by the negative pressure source sucking-off.Being partly with of head 15 front ends has fixing outer cutter assembly 2 on O-ring seal 3, the head 15 screw 16 is inserted in outer cutter assembly 2 rear ends; Packing ring 7 is used to compress and fixed seal ring 6.Front end 18 external diameters of interior cutter 17 coincide [microgap is arranged] with the internal diameter of outer cutter 1, the anterior undergauge of interior cutter place leaves the backwater hole 19 that communicates with the cutter inner chamber, and this hole is used for when interior cutter 17 front ends 18 stop up in resection organization and interior cutter inner chamber constitutes the normal saline loop.Interior cutter 17 front ends 18 be shaped as unicuspid shape, two sharp fork-shaped, middle concave, select to use when being convenient to excise different organizing.
