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 adjustable medical scalpel for the surgery Minimally Invasive Surgery.
Background technology
Progress along with science, the development of society, the raising of Medical Technology, arthrocsopic surgery as the joint surgery important component part can carry out excision and the reparation of intraarticular pathological tissues under Wicresoft's condition, it all is that many arthrotomy operations were incomparable in the past to the accuracy of diagnosis and the reparation of intraarticular illness, has painful few, recover fast, reduce the 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 Wicresoft.
The arthroscope medical scalpel is the key factor that guarantees high quality surgical as operating equipment indispensable in the arthrocsopic surgery.Referring to accompanying drawing 1, existing scalpel generally includes an outer tube 1 and an inner tube 2 and power connector 8, and in use, the pipe shaft partial insertion of inner tube 2 is in the pipe shaft through hole of outer tube 1, under the drive of dynamical system, inner tube 2 high speed rotating and outer tube 1 are in conjunction with the effect that reaches cutting.
The pipe shaft of above-mentioned existing scalpel part mostly can not be crooked, can only be vertically or inclination enter ill position, but that the human synovial shape mostly is greatly is circular-arc, this just causes scalpel in use to be difficult to arrive some glenoid circular-arc positions; Other has the part scalpel can only single angle single use deflectable in operation, and this has brought trouble with regard to the treatment of giving diffusivity disease patient, and all patient parts can not effectively arrive, and must deal with in addition, make troubles to doctor's operation, bring 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 adjustable medical scalpel of angle.
The present invention includes inner tube, outer tube and power connector, the local location that inner and outer tubes are identical is flexible pipe; Be provided with moving sleeve, pull bar on the outer tube, 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 connector 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 mobile 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 connector 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 scalpel can arrive some glenoid circular-arc positions, so that operation is more thorough, brings convenience to doctor's operation, improves the operation quality.
Description of drawings
Fig. 1 is the part sectioned view of existing medical scalpel.
Fig. 2 is the structural representation of adjustable medical scalpel off working state of the present invention.
Fig. 3 is the structural representation of adjustable medical scalpel case of bending 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 described in further details.
As shown in Figure 2, the present invention includes inner tube 1 and outer tube 2, inner tube 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; End for the power connector 8 that links 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 11 of offering on the power connector 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 as follows:
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 inner and outer tubes all is flexible pipes, therefore can bending, thus 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, such as peeling knife of great saphenous varicose vein excision etc.
