Description
Technical field
This utility model relates to a kind of operation machinery, relates in particular to a kind of medical joint Cutting instrument for cervical intervertebral disc hyperplasia that cuts and repair for the pathological changes joint tissue.
Background technology
Usually need the pathological changes joint tissue is cut and repairs in medical operating, the joint Cutting instrument for cervical intervertebral disc hyperplasia is an instrument commonly used in the existing medical skill.Patent document about the joint Cutting instrument for cervical intervertebral disc hyperplasia also has a lot, as Chinese patent: " the medical electronic Cutting instrument for cervical intervertebral disc hyperplasia mobile phone of through type (CN2617317Y) ", it discloses a kind of medical Cutting instrument for cervical intervertebral disc hyperplasia, and its motor and cutter are out-of-alignments, need by meshed transmission gear the structure more complicated.The motor and the cutter of present medical joint Cutting instrument for cervical intervertebral disc hyperplasia are coaxial, designs simplification, but there is bending part in the attraction passage that is provided with in the main frame, stops up easily when attracting.
Summary of the invention
This utility model has mainly provided a kind of simple in structure, and technology is succinct, and is easily manufactured, do not allow susceptible to plugging medical joint Cutting instrument for cervical intervertebral disc hyperplasia; Solve the technical problem that existing in prior technology attracts passage to stop up easily.
This utility model also provides a kind of simultaneously can implement high-temperature sterilization, the medical joint Cutting instrument for cervical intervertebral disc hyperplasia that the security reliability of medical apparatus and instruments is higher; Solve the joint Cutting instrument for cervical intervertebral disc hyperplasia that exists in the prior art and can only take soaking disinfection, the technical problem that security reliability is stable inadequately.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of medical joint Cutting instrument for cervical intervertebral disc hyperplasia, comprise motor, motor is arranged in the main frame, front end at motor is provided with cutter, the centrage of described motor and the central lines of cutter, be provided with suction catheter in the described main frame, the outer attraction of described suction catheter and main frame is taken over to removably connecting.Motor and the coaxial setting of cutter have omitted both disalignment drive mechanisms, make overall structure more simple, the transmission better effects if.In main frame, add an independently suction catheter, suction catheter can be made according to original attraction passage, make suction catheter separately than attracting via process simply a lot of by boring in the main frame, and the independent manufacturing of suction catheter can guarantee the smooth transition in the bending place, prevented blockage phenomenon in the attraction process.Attract by suction shaft control, attract thing to take over directly and discharge, thereby finish the process that planing attracts by the attraction of suction catheter and main frame outside.
As preferably, described suction catheter is positioned at the top of motor, is arciform; The front end of described suction catheter is provided with suction shaft.Because suction catheter is to be fixed on the main frame after the processing separately again, so its shape can be according to the size and the shape of main frame, and can allow the shaped design that attracts thing to seamlessly transit.Arciform suction catheter has satisfied above-mentioned requirement, can allow smoothly attract thing by the suction catheter sucking-off.
As preferably, described suction catheter is fixed by welding on the main frame, described suction catheter with attract to take over to being threaded.Suction catheter is welded on the main frame, can ensure the stability of whole medical apparatus and instruments, is difficult in the course of the work rocking, and improves the stability of work.Suction catheter and attraction are taken over and is threaded, and is simple in structure, and conveniently install and remove and clean.
As preferably, be provided with resistant to elevated temperatures O shape circle at described suction catheter with between attracting to take over.Resistant to elevated temperatures O shape circle is set, can conveniently Cutting instrument for cervical intervertebral disc hyperplasia be placed in the hot environment and sterilizes, improve the safety in utilization of apparatus.
As preferably, an end of described motor links to each other with interior cutter by coupling joint, and described coupling joint is socketed with the high temperature high voltage resistant oil sealing outward, is provided with high temperature resistant O shape circle at the other end of motor.The both sides of motor all are provided with exotic material sealing, also are in order to ensure that the joint Cutting instrument for cervical intervertebral disc hyperplasia can disinfection in high temperature and high pressure environment, make that sterilization is more thorough that it is safer to work.
Therefore, medical joint of the present utility model Cutting instrument for cervical intervertebral disc hyperplasia has following advantage: 1, independently suction catheter is set in main frame, has prevented to take place to attract the passage phenomenon of blocking, make the use of medical apparatus and instruments more convenient and smooth and easy; 2, in the junction that two ends, suction catheter and the attraction of motor are taken over resistant to elevated temperatures sealing ring is set, has improved sealing effectiveness, make apparatus under the situation of High Temperature High Pressure, to carry out disinfection simultaneously, improved the safety of using apparatus; 3, motor and the coaxial setting of cutter, transmission is more stable, the efficient height, merit is decreased little.
Description of drawings:
Fig. 1 is the sketch map of medical joint of the present utility model Cutting instrument for cervical intervertebral disc hyperplasia.
The concrete thing mode of implementing:
Below by embodiment, and in conjunction with the accompanying drawings, the technical scheme of utility model is described in further detail.
Embodiment:
As shown in Figure 1, a kind of medical joint Cutting instrument for cervical intervertebral disc hyperplasia, comprise main frame 13, in main frame 13, be provided with motor 28, one end of motor 28 is socketed with oil-sealing sleeve 26, oil-sealing sleeve 26 is loaded onto High Temperature High Pressure oil sealing 15, be pressed in the main frame 13 after refilling high temperature resistant O shape circle 27, the other end of motor 28 is fixed in the main frame 13 by stationary bushing 9 and locknut 8, and by high temperature resistant O shape circle 5, gasket seal 4 and high temperature resistant O shape circle 7 and locking wire cover 1 and extraneous sealing, motor 28 rear portion lines are connected with peripheral control unit by high-temperature-resisting silicon rubber line 3.Front end at motor 28 is connected with coupling joint 16 with pin, and the front end of coupling joint 16 is provided with cutter, and cutter comprises interior knife bar 23, interior tool rest 24, outer knife bar 22 and outer tool rest 21.Interior knife bar 23 is connected with interior tool rest 24 usefulness high-temperature plastics, cutter stage clip 25 in loading onto; Outer knife bar 22 also is connected with high-temperature plastic with outer tool rest 21, is connected with lock tool rest 18 with pinning 20 by cutter lock 19, and removable, lock tool rest 18 links to each other with main frame 13 by attaching nut 17.
