Description

A kind of bushing type splanchnocoel attracts head

This utility model relates to a kind of bushing type splanchnocoel and attracts head, belongs to surgical medical equipment.

In surgical operation, often need to use a kind of attraction head of making by metal or macromolecular material, absorb blood, sepage and the Digestive system etc. that occur in the operation at any time,, be convenient to operation technique and carry out smoothly to keep operating field clear.Splanchnocoel commonly used at present attracts head to be made of a straight shape inner suction pipe and trocar sheath, has to attract the hole around the tube wall at trocar sheath suction inlet place.In the use, if when need making " point " shape and attracting, negative pressure on a termination of inner suction pipe then, the other end is on the required absorption thing can absorb blood, sepage and the Digestive system etc. that occur in the operation; If when needing to do " all around " attraction, then outside inner suction pipe, put trocar sheath again.This weak point of head that attracts is: the visual field that 1, stops the doctor; 2,, when " point " shape attracts and attract switching frequent, use very inconvenient all around because inner suction pipe and trocar sheath are split type; 3, the dynamics of Xi Yining can't be regulated, and dark excessively sometimes negative pressure can cause the damage of tissue.

The purpose of this utility model provides a kind of bushing type splanchnocoel and attracts head, and it has integral structure, makes the patient easy to operate, and has clear visual field, the advantage that appeal is adjustable.

For achieving the above object, this utility model comprises inner suction pipe and trocar sheath, around the tube wall of trocar sheath, have and attract the hole near suction inlet, it is characterized in that: also comprise outer cannula hub, the inner suction pipe handle, nut and attraction mouth, it is circular-arc that trocar sheath and inner suction pipe all are, trocar sheath one end is connected on the outer cannula hub, the other end is equipped with the attraction mouth, one end of inner suction pipe places in the trocar sheath, the other end connects on the inner suction pipe handle that slides in the outer cannula hub, the inner suction pipe handle other end extends outside the outer cannula hub and connects negative pressure, has gathering sill on the outer cannula hub, is equipped with protruding key on trocar sheath and the inner suction pipe handle, protruding key is in the gathering sill, outer cannula hub and inner suction pipe handle relatively move and can make inner suction pipe do telescopic moving in trocar sheath, and nut is fixed on the outer cannula hub by screw thread, in case trocar sheath comes off.The inner suction pipe handle is connected negative pressure in the use, relatively moves by outer cannula hub and inner suction pipe handle and can do the attraction of " point " shape or do " all around " to attract, also the scalable appeal.

This utility model is owing to increased outer cannula hub and inner suction pipe handle, form the structure of integral type, make the patient in use only with hand refer to that mobile outer cannula hub both can do the switching that " point " shape or " all around " attract, can do the adjusting of " point " appeal again, brought convenience to use; Because inner suction pipe and trocar sheath all are circular-arc, make patient's the visual field very clear again.In addition, this utility model also has advantage simple in structure.

Provide embodiment of the present utility model and accompanying drawing below, and be described further:

Fig. 1, be structure cut-away view of the present utility model.

By shown in Figure 1, this utility model is made of inner suction pipe 2, outer cannula hub 3, inner suction pipe handle 4, nut 5, attraction mouth 7 and trocar sheath 1.Trocar sheath 1 and inner suction pipe 2 all are circular-arc, and trocar sheath 1 one ends are connected on the outer cannula hub 3, and the other end is equipped with and attracts mouth 7.Around the tube wall of trocar sheath 1, have and attract hole 6 near suction inlet.One end of inner suction pipe 2 places in the trocar sheath 1, and the other end connects on the inner suction pipe handle 4 that slides in the outer cannula hub 3, and inner suction pipe handle 4 other ends extend outside the outer cannula hub 3 and connect negative pressure.For preventing to relatively rotate between trocar sheath 1 and the inner suction pipe 2, on outer cannula hub 3, have gathering sill 8, be equipped with protruding key 9,10 on trocar sheath 1 and the inner suction pipe handle 4, protruding key 9,10 is in the gathering sill 8.Outer cannula hub 3 relatively moves with inner suction pipe handle 4 and can make inner suction pipe 2 do telescopic moving in trocar sheath 1, and nut 5 is fixed on the outer cannula hub 3 by screw thread, in case trocar sheath 1 comes off.Inner suction pipe handle 4 is connected negative pressure in the use, if when needing to do the attraction of " point " shape, outer cannula hub 3 and inner suction pipe handle 4 suction inlet that makes inner suction pipe 2 that relatively moves heads in the horn mouth that attracts mouth 7, then absorbs thing by attracting mouth 7 to suck, through inner suction pipe 2,4 sucking-offs of inner suction pipe handle; If in the time of need doing " all around " attraction, make inner suction pipe 2 withdraw from the horn mouth and attraction 6 positions, hole of attraction mouth 7, then absorb thing from attracting hole 6 suctions, through inner suction pipe 2,4 sucking-offs of inner suction pipe handle.In operation, the degree of tightness that can utilize the suction inlet of inner suction pipe 2 and attract to mesh between the horn mouth of mouth 7 is regulated the dynamics that " point " shape attracts.
