Description
Technical field
The utility model is related to the field of medical instrument technology, especially a kind of thoracic cavity aspirator.
Background technology
Bleeding that aspirator is used to be precipitated in operation, exudate, agricultural, the content etc. in thoracic organ, reduce and infect
Chance；Aspirator also in the course of surgery, when detaching lesion, plays barrier surrounding organ function, makes surgical field of view and solution simultaneously
It cuts open level to be more clear, to save operating time, improves surgical quality.The principle of aspirator is very simple, is exactly by one
The method of determining manufactures the negative pressure state of its sucking head, and such atmospheric pressure will squeeze the substance outside sucking head into sucking head, complete
It is operated at attracting.
Traditional thoracic cavity aspirator is a hard tube body with sucking head, and the front end of tube body is sucking head, on sucking head
Offer suction hole, the rear end connection negative pressure mechanism of tube body；However since suction hole cannot effectively control the size of negative pressure,
Very big inconvenience is brought to operation.
Chinese patent CN104645426A discloses a kind of adjustable thoracoscope suction apparatus head comprising suction tube, band
Sucking head, discharge pipe and the debugging switch of suction hole, debugging switch ends are separately connected suction tube and discharge pipe, debug on switch
It is provided with regulating valve；This patent is by being arranged debugging switch so that the negative pressure pressure in suction tube becomes adjustable, can be according to hand
Art status adjustment uptake size meets operation and requires.But there is no open debugging switch and regulating valves in text
Concrete structure needs a human hand held suction tube according to different rotary formula regulating valve during adjusting negative pressure pressure, another
People operates regulating valve and can be adjusted, it has not been convenient to perform the operation；And sucking head is structure as a whole with suction tube in this article, and attracts
After head is a flat structure, is easy to accidentally injure internal organs in thoracic cavity in operation, and sucking head blocks, it has not been convenient to clean.
Invention content
The utility model technical issues that need to address are to provide that one kind is conveniently operated and postoperative easy cleaned thoracic cavity is inhaled
Lead device.
In order to solve the above technical problems, technical solution adopted in the utility model is as follows.
The front end of thoracic cavity aspirator, including tube body, tube body is provided with sucking head, the rear end connection negative pressure mechanism of tube body, institute
It includes the bulb being fixedly connected and connecting section to state sucking head, several suction holes of connection tube cavity is offered on bulb, even
The other end and the tube body front end screw thread for taking over portion are equipped；The tube body rear end is fixedly installed negative pressure connector, and tube body is close
The handgrip part of rear end be provided with vacuum magnitude in control pipe body by compressing switch.
Above-mentioned thoracic cavity aspirator, it is described by compressing switch including the right plate and left plate for being oppositely arranged on tube two sides, it is right
Fixed setting is useful for the package cylinder of connection pipe body on side plate, wraps up the blind hole that connection tube cavity is offered in cylinder, blind
Be fitted in hole move back and forth, in control pipe body conducting sectional area piston rod；The outer end of the piston rod is fixed with left plate
Connection.
Above-mentioned thoracic cavity aspirator, the blind hole are provided with sealing ring close to the outer end of left plate.
Above-mentioned thoracic cavity aspirator, the negative pressure connector are the serial sphere structure of decrement shape with barrier structure.
As a result of above technical scheme, technological progress acquired by the utility model is as follows.
The utility model by tube body and sucking head by using split type screw connection structure, and sucking head uses bulb knot
Structure can not only be removed and be cleaned after surgery, facilitate surgical procedure, but also be can avoid sucking head and damaged chest in the course of surgery
The internal organs of intracavitary.The negative pressure connector of tube body rear end setting uses the serial sphere structure of decrement shape with barrier structure, both facilitates
The installation of negative pressure mechanism, prevented also from negative pressure, mechanism falls off phenomenon in art.Push type structure is used by compressing switch, is made
The negative pressure in tube body can be adjusted in real time by obtaining a people in the course of surgery, facilitated medical staff's operation, improved hand
Art efficiency.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is described in the utility model by the vertical view to compress switch.
Wherein：1. tube body, 2. sucking heads, 21. connecting section, 22. bulbs, 3. negative pressure connectors, 4. by compressing switch, 41.
Right plate, 42. left plates, 43. package cylinders, 44. piston rods, 45. sealing rings.
Specific implementation mode
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
A kind of thoracic cavity aspirator, structure is as shown in Figure 1, include tube body 1, the front end of tube body 1 is provided with sucking head 2, manages
The rear end connection negative pressure mechanism of body.
Sucking head 2 includes the bulb 22 being fixedly connected and connecting section 21, and connection tube cavity is offered on bulb 22
Several suction holes, the other end and tube body front end screw thread of connecting section are equipped.The tube body of sucking head is set in the utility model
Front end may also be configured to bending structure, as shown in Figure 1, between the angle of bending is 160 ~ 170 °, facilitates and draws product in art
Liquid.
The rear end of tube body 1 is fixedly installed negative pressure connector 3, and negative pressure connector 3 is that the decrement shape with barrier structure is serial
Sphere structure, as shown in Figure 1, the decrement serial sphere structure of shape facilitates the hose of negative pressure mechanism to pass through, group facilitates fixation every structure
Hose prevents hose in art because movement falls off.
Handgrip part of the tube body close to rear end is provided with by compressing switch 4, for the vacuum magnitude in control pipe body.By pressing off
