Abstract
The utility model relates to a suction force regulating valve of controllable suction apparatus of neurosurgery, which consists of a base, a valve outer cover, a plug valve inner core, an inner core fixing cover and a connecting tube. The valve outer cover is constantly connected with the base and provided with two holes corresponding to the through holes on the plug valve inner core which is relatively fixed by the inner core fixing cover in the valve outer cover with the two holes respectively connected with the connecting tubes. The utility model is a suction force regulating valve of controllable suction apparatus of neurosurgery with continuous and exact regulation of suction force and simple and convenient use.
Description
This utility model relates to the suction pump suction control valve that uses in a kind of neurosurgery.
Suction pump is an apparatus indispensable in the neurosurgery, and it has the liquid of absorption and tumor, the tissue that dissociates, collaborative bipolar coagulation hemostatic function.In the use, need be according to the suction of the different adjustment suction pump of suction material, such as: when absorbing liquid substance, need suction smaller, during absorptive tissue, need suction big.The suction pump that uses is to reach the purpose of regulating suction by the suction catheter of selecting different tube diameters for use, the pore of closing or open suction catheter, the central negative pressure system of adjusting at present.That these methods exist is time-consuming in operation process, influence patient's attention and suction is regulated the shortcoming that changes not obvious, inaccurate (adjusting of central negative pressure system has only large and small two grades, can not regulate continuously), makes troubles and inconvenience to operation.
The purpose of this utility model provides a kind ofly can continuously, accurately regulate suction pump suction, controlled neurosurgery suction pump suction control valve easy to use.
For achieving the above object, this utility model is taked following design: a kind of controlled neurosurgery suction pump suction control valve, it comprises: base, valve body overcoat, cock-type valve body inner core, inner core fixed cap, connection tube, described valve body overcoat is fixedly connected on the base, on the described cock-type valve body inner core through hole is arranged, described valve body overcoat also has two relative holes with respect to the position of this through hole, described cock-type valve body inner core in described valve body overcoat, respectively is connected with connection tube outside two holes that described valve body puts by inner core fixed cap relative fixed outward.
This utility model is owing to adopt above-mentioned design, make it in use, by the rotary valve inner core, thereby the through hole of regulating on the inner core comes the flow of control valve to regulate the suction of suction pump with the relative position that valve body puts two relative holes outward, the hole that puts outside hole on the inner core and valve body is fully on time, flow maximum by valve, the suction of suction pump is also maximum, otherwise when stagger fully in the hole that puts outside hole on the inner core and the valve body, by the flow minimum of valve, the suction of suction pump is also minimum.Use this control valve to avoid fully could regulating suction by the suction catheter of selecting different tube diameters for use, the pore of closing or open suction catheter, the central negative pressure system of adjusting in the prior art, time-consuming in the operation process, influence patient's attention and suction and regulate and change not obvious, inaccurate shortcoming, the great convenience of having given surgical band.It is a kind ofly can continuously, accurately regulate suction pump suction, controlled neurosurgery suction pump suction control valve easy to use.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is this utility model overall structure sketch map
Fig. 2 is this utility model major part sectional structure sketch map
As shown in Figure 1, 2, this utility model is mainly combined by base 1, valve body overcoat 2, cock-type valve body inner core 3, inner core fixed cap 4, connection tube 5.Described valve body overcoat 2 is fixedly connected on the described base 1, on the described cock-type valve body inner core 3 through hole 6 is arranged, its top has knob 7, described valve body overcoat also has two relative holes 8 with respect to the position of this through hole 6, described cock-type valve body inner core 3 is arranged in described valve body overcoat 2, described inner core fixed cap 4 is threadedly connected to the top of described valve body overcoat 2, there is the hole that can supply described cock-type valve body inner core 3 upper knobs 7 to stretch out its center, and connects described connection tube 5 respectively outside two holes on the described valve body overcoat 2.Can indicate scale on the inner core fixed cap, corresponding with the pointer that knob 7 indicates, so that user makes things convenient for the opening degree of control valve, thus the size of regulating suction pump suction.
During use, the connection tube of a side connect cause the suction catheter that inserts human body, the connection tube of opposite side then connects suction pump, after connecting, the material that the doctor can attract is as required regulated the opening degree of control valve, and this regulates not only continuous, accurate, and very simple and convenient.
