Detailed description of the invention
Traditional scalpel is due to staight shank and angle is non-adjustable, is subject to many restrictions in use, and especially for the operation of endocardial, straight shape structure is difficult to the actual needs meeting internal mute.This programme proposes a kind of scalpel can adjusting blade angle in advance according to focus, facilitates the excision of focus.
A kind of universal can illumination scalpel, comprise cutter head 1 and handle 6, cutter head 1 removably installs blade, connected by movable joint between described cutter head 1 and handle 6, movable joint by multiple series connection and spaced ball seat 5 and regulate ball 4 to form, and by through ball seat 5 with regulate the rope 8 of ball 4 center setting to be connected; Described handle 6 is provided with for haul 8 clamp device, scalpel is also provided with light source 19.
As shown in Figure 1, the movable joint be arranged between cutter head 1 and handle 6 is used for adjusting the angle of whole scalpel.Because the degree of freedom of whole movable joint is very high, the adjustment of cutter head 1 direction, angle in very large range can be carried out.Movable joint is can be relatively-stationary, and movable joint is connected by rope 8, hauls 8, also just secure movable joint by clamp device.Owing to regulating ball 4 and ball seat 5 structure, make ball seat 5 and regulate between ball 4 to coordinate with multiple angles, thus make whole movable joint be put into various shape.The Adjusting Shape of movable joint can make cutter head 1 be in the advantageous angle of convenient cutting depths focus, is also convenient to go deep into the position that coventional scalpel is difficult to arrive simultaneously, and additionally need not expands otch.
Particularly, regulating ball 4 to be ball, being provided with for the through hole by rope 8 through regulating the center of ball 4; Described ball seat 5 comprises one section of cylinder, two end faces spherically shape depression of cylinder, and the size of depression adapts with regulating ball 4; Ball seat 5 center is also provided with through hole.
As depicted in figs. 1 and 2, why angle is adjustable on a large scale in movable joint, is because have employed the structure regulating ball 4 and ball seat 5, regulates ball 4 can rotate in certain limit in ball seat 5, and when arranging multiple adjustment ball 4 and ball seat 5, whole movable joint just can show various shape.And owing to being the fit system of ball and dome shape depression, when so ball turns to different directions, as long as be among depression, just keep being relatively fixed between energy and ball seat 5.For original shape when overlapping to regulate the through hole in ball 4 and the through hole in ball seat 5, owing to being connected by rope 8 between ball seat 5 and adjustment ball 4, when regulating ball 4 position change, regulate the through hole in ball 4 can to offset within the specific limits relative to the through hole in ball seat 5, outward manifestation is then that movable joint global shape changes.Adjusting Shape well after, tightened up by rope 8, owing to regulating the frictional force between ball 4 and ball seat 5, the ball seat 5 and regulate the through hole of ball 4 to overlap when rope 8 tightens up, then the shape that rope 8 tightens up rear movable joint just obtains fixing.
Clamp device comprises the movable adapter sleeve 7 be arranged on handle 6, and adapter sleeve 7 can along the axially-movable of handle 6; Adapter sleeve 7 is provided with push pedal 11, when adapter sleeve 7 moves, drives rope 8 to move by push pedal 11.
A kind of rope 8 tightening device is arranged on by the end of rope 8 on adapter sleeve 7, when adapter sleeve 7 opposite handle 6 is tightened, drives rope 8 to move, thus haul 8.Due between movable joint when rope 8 does not tighten up spacing very little, and the angle adjustment of spacing little so enough between movable joint, so haul 8 time also only need to drive rope 8 to advance a bit of distance, the object of tightening up can be reached.
Handle 6 inside offers cavity 13 vertically, cavity 13 wall is provided with a countershaft 10; The front end of two bracing wires 12 walks around the end that rotating shaft 10 is connected to rope 8 jointly respectively, and the end of two bracing wires 12 is separately fixed in a push pedal 11, and push pedal 11 utilizes push rod 15 to be fixed on adapter sleeve 7.Handle 6 outer wall is provided with external screw thread 9, adapter sleeve 7 inwall is provided with the female thread 14 coordinated with external screw thread 9.
As shown in Figure 3, the cavity 13 of handle 6 inside is for passing through rope 8.Rope 8 end is walked around rotating shaft 10 by two bracing wires 12 and is arranged, and bracing wire 12 end is fixed in push pedal 11.Push pedal 11 and adapter sleeve 7 are integrative-structures, when adapter sleeve 7 turns, move towards near cutter head 1 direction, push pedal 11 is now driven also to move towards near cutter head 1 direction, push pedal 11 is moved and is driven bracing wire 12 to move, bracing wire 12 changes direction through rotating shaft 10, then pull rope 8 to move towards the direction away from cutter head 1, so just tightened up rope 8.By the mode of this threaded engagement, simple to operate laborsaving, regulate and also facilitate.
Adapter sleeve 7 one end open, the other end is provided with end cap 16, and it is inner that described push rod 15 is arranged on adapter sleeve 7, and the end of push rod 15 is cemented on end cap 16 by a rotating disk 18.
When adapter sleeve 7 turns, in order to anti-throw-out lever 15 simultaneously fastened cover 7 there is situation about being blocked by cavity 13 inwall with rotation, can arrange a rotating disk 18 at two push rod 15 ends, rotating disk 18 is arranged in end cap 16 by axle, can rotate around axle.So when turning adapter sleeve 7, the power of direction of rotation is laid down by the axle of rotating disk 18, and the power of adapter sleeve 7 axially-movable then passes to push pedal 11 through push rod 15, and push pedal 11 is travelled forward.
Adapter sleeve 7 outer wall is intervally distributed with multiple along the axially extended antiskid plate 17 of adapter sleeve 7.Antiskid plate 17 can conveniently turn adapter sleeve 7.
Cutter head 1 is connected by holder 3 with between movable joint, and cutter head 1 is by threadingly removably installing between installing rack 2 and holder 3; The front end of described rope 8 is fixed in holder 3.
For installing blade on cutter head 1, existing scalpel blade can be contained on cutter head 1 in the mode of plug-in mounting.And for the cutter head 1 of different size, the mode by dismounting is arranged on holder 3.Cutter head 1 is fixedly installed on a fixed mount, and fixed mount is provided with bolt, can be fastened in holder 3.The front end original position of rope 8 is exactly holder 3, therefore needs to be fixed in holder 3.
Form the ball seat 5 of movable joint and regulate the size of ball 4 to reduce gradually along the direction near cutter head 1.
Due to the closer to cutter head 1 position, just the closer to focus during operation, and relative utilized space is just narrower and small, when therefore arranging, reduces all gradually near the adjustment ball 4 in cutter head 1 direction and the size of ball seat 5, ensures working place.
In addition, scalpel is also provided with light source 19.
Be holder near the immediate parts of tool bit part, due to focus darker time, it is very poor that knife head for surgical arrives lesions position rearward vision, is not easy to doctor's operation.Therefore light source can be set on scalpel, and according to structure of the present utility model, light source is preferably disposed on holder, specifically can arrange like this: the screwed hole coordinated with cutter head is offered in holder inside, this part space may be used for holding and is set to the button cell that light source provides electric power, and LED is embedded on the outer wall of holder, around setting.The positive pole of LED is directly connected with battery, and negative pole arranges a shell fragment, only has when cutter head utilizes installing rack to rotate in holder, the end of installing rack by shell fragment top to and battery terminal contact, now lamp is bright.As long as and unload cutter head after finishing using, shell fragment depart from and battery terminal contact, LED is gone out.
