Description
Technical field
This utility model relates to a kind of suction catheter with micro-hoe scaler, belongs to medical instruments field.
Background technology
Suction catheter and micro-hoe scaler are requisite important use instruments in the surgical operations such as neurosurgery, microsurgery, suction catheter mainly plays attraction blood, organizes body fluid, up-stripping operative site tissue, expose the effect of surgical field of view, micro-hoe scaler is peeled off the tissues such as cutting mucosa, fascia in being mainly used in performing the operation.In the neurosurgery process such as acoustic neuroma, doctor need to will constantly change above two kinds of apparatuses according to operation demand, and complex operation, affects operating time.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of easy to operate, have and attract and peel off two kinds of functions of cutting and can be widely used in the suction catheter with micro-hoe scaler in surgical operation simultaneously.
Suction catheter with micro-hoe scaler described in the utility model, comprise hands handle, body, micro-hoe scaler and hoe scaler control handle, body head is welded with protective sleeve, on the inwall of protective sleeve, be welded with two parallel projections, two projections are divided into the internal cavities of protective sleeve, lower two parts, body afterbody weldering connecting handle, handle front end arranges control hole, rear end suit hoe scaler control handle, the inner side fixing lug boss of hoe scaler control handle, corresponding boss arranges bar shaped gathering sill on handle, boss snaps in bar shaped gathering sill and along bar shaped gathering sill and moves, micro-hoe scaler one end is welded on the front end of hoe scaler control handle, the other end penetrates body inside from the control hole of handle, the cutter head of micro-hoe scaler moves forward and backward in the lower cavity of protective sleeve.
Operation principle and process:
While needing to attract in operation process, first make the cutter head of micro-hoe scaler be positioned at body, then by thumb, regulate the size of control hole to regulate attraction flow; In the time of need to peeling off cutting; with thumb, promote forward hoe scaler control handle; under the drive of hoe scaler control handle; micro-hoe scaler moves forward in body; the head of micro-hoe scaler exposes protective sleeve, can be to organizing and implementing cutting, after having cut; back pull hoe scaler control handle, until micro-hoe scaler is return in body.According to operation demand, above operation can be repeated, different operating required in operation can be met.Simple to operation, function conversion flexibly, without the frequent apparatus of changing, is saved operating time.
In above-mentioned hoe scaler control handle and the space of handle, back-moving spring is installed, corresponding back-moving spring arranges limited block on handle, and limited block is positioned at the front end of back-moving spring.Promote forward hoe scaler control handle, can drive micro-hoe scaler to move forward, after loosing one's grip, in hoe scaler control handle, under the elastic force of back-moving spring, can drive micro-hoe scaler to set back, easy and simple to handle.
The beneficial effect that this utility model compared with prior art had is:
This is with the suction catheter reasonable in design of micro-hoe scaler; can be effectively by together with the function combinations of hoe scaler and two kinds of apparatuses of suction catheter; during attraction; make micro-hoe scaler be positioned at the inner lower of protective sleeve; avoid scratching tissue; when organization need such as running into mucosa is peeled off cutting; only need promote forward hoe scaler control handle; drive micro-hoe scaler to expose body in protective sleeve; to organizing and implementing cutting, simple to operation, function conversion flexibly; without the frequent apparatus of changing, save operating time.

The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Fig. 1～5, suction catheter with micro-hoe scaler comprises handle 1, body 5, micro-hoe scaler 3 and hoe scaler control handle 2, body 5 heads are welded with protective sleeve 6, on the inwall of protective sleeve 6, be welded with two parallel projections 7, two projections 7 are divided into the internal cavities of protective sleeve 6, lower two parts, body 5 afterbody welding handles 1, handle 1 front end arranges control hole 4 (adopting drop-shaped control hole in the present embodiment), rear end suit hoe scaler control handle 2, the inner side fixing lug boss 11 of hoe scaler control handle 2, corresponding boss 11 arranges bar shaped gathering sill 10 on handle 1, boss 11 snaps in bar shaped gathering sill 10 and along bar shaped gathering sill 10 and moves, micro-hoe scaler 3 one end are welded on the front end of hoe scaler control handle 2, the other end penetrates body 5 inside from the control hole 4 of handle 1, the cutter head of micro-hoe scaler 3 moves forward and backward in the lower cavity of protective sleeve 6.During attraction, micro-hoe scaler 3 is return the inner lower of protective sleeve 6, can avoid scratching tissue; During cutting, micro-hoe scaler 3 stretches out protective sleeve 6 outsides, to organizing and implementing cutting.
