Description
Technical field
This utility model belongs to medical instruments field, is specifically related to the Attraction structure after a kind of improvement.
Background technology:
In surgical operation, suction pump is often used to Sterile surgery open country, and in actual mechanical process, suction pump is easy to by blockings such as soft tissue, broken bone bits, in operation process, dredge suction pump can waste the more time again, the progress of operation of slowing down, too increases the risk of patient.Chinese utility model patent CN2834450Y discloses a kind of block-proof suction device on November 8th, 2006, comprises suction pump body, is arranged at manual portion on body and can the tail end of connection plastic sebific duct, is provided with anti-network blocking at the tube cavity of suction pump front end.This block-proof suction device makes simple, easy to operate, effectively can improve the efficiency of operation.But soft tissue, broken bone bits are still deposited on filter screen, be easy to block filter screen, cause attraction not smooth, impact attracts effect.
Utility model content:
In order to solve the problem, this utility model provides the Attraction structure after a kind of improvement, effectively can prevent the blocking of suction pump in operation process, avoid tamper to block screen plate, and structure is simple, easy to operate.
In order to achieve the above object, this utility model adopts following technical scheme: the Attraction structure after a kind of improvement, comprise the rear negative tube that is connected with negative pressure device and be connected with described rear negative tube for suction catheter before attracting, be connected by linkage section between described rear negative tube with described front suction catheter, described linkage section is the structure of expanding that internal diameter is greater than described rear negative tube, described side of expanding structure be provided with protrude from described in expand the accommodation district for holding chip of structure, the inner chamber in described accommodation district communicates with the described inner chamber expanding structure, described expanding in structure is provided with screen plate.
This technical scheme arranges screen plate, is filtered by tamper, and collects tamper by holding district, avoids its blocking screen plate.
As preferably, described screen plate is hoisted by the minimum point of the lumen inlet in described accommodation district and is obliquely installed.The screen plate be obliquely installed can make chip take advantage of a situation under the effect of negative pressure and enter accommodation district, reduces the chance of its delay blocking screen plate.
As preferably, the angle of inclination of described screen plate is 45 ° ~ 60 °, can guarantee that tamper enters and hold district, and not affect again the attraction of waste liquid.
As preferably, the latter half coincident of the lower limb of described screen plate and the entrance of described accommodation district inner chamber, makes tamper enter smoothly and holds district.
As preferably, the entrance of described accommodation district inner chamber is circular, and the internal diameter of described round entrance is equal with the described internal diameter expanding structure, makes tamper can enter accommodation district smoothly.
As preferably, described front suction catheter be provided with near described in expand the active segment of structure, described active segment is scrimp structure, can bend front suction catheter, is convenient to attraction operation.
As preferably, described in expand the outer surface of structure and be provided with axial rib, handled easily.
By implementing technique scheme, this utility model structure is simple, easy to operate, effectively can prevent the blocking of suction pump in operation process, avoids tamper to block screen plate.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of this utility model one embodiment.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Attraction structure after a kind of improvement as shown in Figure 1, comprise the rear negative tube 10 that is connected with negative pressure device and be connected with rear negative tube 10 for suction catheter 11 before attracting, 13 are connected by linkage section, for internal diameter is greater than the structure of expanding of rear negative tube 10 between rear negative tube 10 with front suction catheter 11.For the ease of attraction operation, especially there is corner district at field of operation, front suction catheter 11 is provided with the active segment of the one end near rear negative tube 10, is scrimp structure 111, can change more broadly and attract direction; The outer surface of structure of expanding is provided with axial rib 133, is convenient to hand-held.The blocking of soft tissue, broken bone bits etc. is had in attraction process, expanding the side of structure is provided with that to protrude from what expand structure be circular accommodation district 131 for holding the entrance of chip, the inner chamber holding district 131 with expand the inner chamber of structure and communicate, expand and to be provided with lower limb and the screen plate 132 of the latter half coincident of entrance holding district 131 inner chamber in structure, its internal diameter is with to expand the internal diameter of structure equal; Screen plate 132 is hoisted by the minimum point of the lumen inlet holding district 131 and is obliquely installed, and angle of inclination is 45 ° ~ 60 °, and the present embodiment is 50 °.
