Abstract
The invention discloses an adjustable medical cutting scalpel, which comprises an inner tube, an outer tube and a power connector. A hose is located at identical local positions of the inner tube and the outer tube, the outer tube is provided with a moving sleeve and a drawbar, one end of the drawbar is rotatably connected with the outer tube between the hose and a scalpel head, the other end of the drawbar is rotatably connected with the moving sleeve, an adjusting nut is sleeved on the moving sleeve, the moving sleeve and the adjusting nut are connected in a threaded manner, one end of the power connector extends into the adjusting nut, and the power connector and the adjusting nut can rotate relatively. The angle of the scalpel head can be changed optionally, so that the scalpel can reach a more concealed sickness position inconvenient to reach, sufferings of a patient are removed, and the adjustable medical cutting scalpel brings convenience for doctors and improves surgery quality.
Description
Technical field
Patent of the present invention belongs to medical instruments field, relates to a kind of medical cutter that cuts of scalable that is used for the surgery Minimally Invasive Surgery.
Background technology
Along with the progress of science, the development of society, the raising of Medical Technology; Arthrocsopic surgery as the joint surgery important component part can carry out the excision and the reparation of intraarticular pathological tissues under Wicresoft's condition; It all is that many in the past arthrotomy operations are incomparable to the accuracy of the diagnosis and the reparation of intraarticular illness, has painful few; Recover fast, reduce advantages such as post-operative complication and surgery cost are low.The development of arthrocsopic surgery has demonstrated fully the development trend of modern surgery Wicresoftization.
The medical cutter that cuts of arthroscope is the key factor that guarantees high quality surgical as operating equipment indispensable in the arthrocsopic surgery.Referring to accompanying drawing 1; The existing cutter that cuts generally includes pipe 2 and power union joint 8 in an outer tube 1 and one, and in use, the pipe shaft of interior pipe 2 partly is inserted in the pipe shaft through hole of outer tube 1; Under the drive of dynamical system, interior pipe 2 high speed rotating and outer tube 1 combine to reach the effect of cutting.
The above-mentioned existing pipe shaft part that cuts cutter mostly can not be crooked, can only vertically or tilt to get into ill position, but the human synovial shape be circular-arc mostly that this just causes cutting cutter and in use is difficult to arrive some glenoid circular-arc positions; Other has part to cut cutter can only single angle single use deflectable in operation, and this has brought trouble just for diffusivity disease patient's treatment, and all patient parts can not effectively arrive, and must deal with in addition, operates making troubles to the doctor, brings misery to the patient.
Summary of the invention
The object of the present invention is to provide a kind of pipe shaft can arbitrarily, repeatedly adjust the medical cutter that cuts of scalable of angle.
The present invention includes interior pipe, outer tube and power union joint, the local location that interior pipe is identical with outer tube is a flexible pipe; Outer tube is provided with moving sleeve, pull bar, and the outer tube between pull bar one end and flexible pipe and the cutter head is rotationally connected, and the other end and moving sleeve are rotationally connected; Be set with adjusting nut on the moving sleeve, between the two for being threaded; One end of power union joint stretches in the adjusting nut, can relatively rotate between the two.
In order to limit the displacement of adjusting nut, prevent that it from coming off from moving sleeve pipe in rotary course, the outside of adjusting nut also is provided with end cap, and this end cap stretches in the cannelure of offering on the power union joint simultaneously.
Can not rotate in order to guarantee moving sleeve to move, moving sleeve has chute vertically, is provided with the spline part in the groove, and an end of this spline part stretches in the outer tube.
Pipe shaft of the present invention can be arbitrarily, angle changing repeatedly, and therefore in use cutting cutter can arrive some glenoid circular-arc positions, makes that operation is more thorough, bringing convenience to doctor's operation, improves the operation quality.
Description of drawings
Fig. 1 is the existing medical part sectioned view that cuts cutter.
Fig. 2 is the medical structural representation that cuts the cutter off working state of scalable of the present invention.
Fig. 3 is the medical structural representation that cuts the cutter case of bending of scalable of the present invention.
Fig. 4 is the A-A profile of Fig. 2 and Fig. 3.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is explained further details.
As shown in Figure 2, pipe 1 and outer tube 2 in the present invention includes, interior pipe 1 and outer tube 2 are flexible pipe 3 near the part of the same position of head 4.Moving sleeve 6, pull bar 5 and adjusting nut 9 are set on the outer tube 2, and the outer tube 2 between pull bar 5 one ends and flexible pipe 3 and the cutter head is rotationally connected, and the other end and moving sleeve 6 are rotationally connected.Adjusting nut 9 is sleeved on moving sleeve 6, between the two for being threaded; One end of the power union joint 8 that is used for linking to each other with dynamical system stretches in the adjusting nut 9, can relatively rotate between the two.The outside of adjusting nut 9 is provided with end cap 10, and this end cap 10 stretches in the cannelure of offering on the power union joint 11 simultaneously.
As shown in Figure 4, moving sleeve 6 has chute vertically, is provided with pin 7 in the groove as the spline part, and an end of pin 7 stretches into and is fixed in the outer tube 2.
The adjustment process of pipe shaft angle of the present invention is following:
Referring to Fig. 3, rotate adjusting nut 9, moving sleeve 6 moves right along with the rotation of adjusting nut 9, and the left end of pull bar 5 rises thereupon, because the part of interior pipe and outer tube all is flexible pipes, so can bending, thereby pipe shaft shape is had a certain degree.
The structure that the present invention relates to also is applicable to the planing operating theater instruments of other principle of similitude, like rotary-cut cutter of great saphenous varicose vein excision etc.
Claims (3)
1. the medical cutter that cuts of scalable comprises interior pipe, outer tube and power union joint, it is characterized in that:
The interior pipe local location identical with outer tube is flexible pipe; Outer tube is provided with moving sleeve, pull bar, and the outer tube between pull bar one end and flexible pipe and the cutter head is rotationally connected, and the other end and moving sleeve are rotationally connected; Be set with adjusting nut on the moving sleeve, between the two for being threaded; One end of power union joint stretches in the adjusting nut, can relatively rotate between the two.
2. the medical cutter that cuts of scalable as claimed in claim 1 is characterized in that the outside of adjusting nut is provided with end cap, and this end cap stretches in the cannelure of offering on the power union joint simultaneously.
3. according to claim 1 or claim 2 the medical cutter that cuts of scalable is characterized in that moving sleeve has chute vertically, is provided with the spline part in the groove, and an end of this spline part stretches in the outer tube.
