Description

Pneumatic sacculus oppression drainage rifle
Technical Field
The utility model relates to the technical field of clinical surgical instruments, in particular to a pneumatic balloon compression drainage gun.
Background
Blunt dissection refers to a surgical operation method for separating original intact soft tissues by using a scalpel handle, hemostatic forceps, fingers and other tools. Blunt dissection is commonly used to loosen connective tissue, including flat muscle, interstitial space, tumor removal, dissection of cystic extracapsular connective tissue or adhesion tissue, and the like. Can prevent accidental injury of nerve and blood vessel, avoid excessive opening of tissue, and reduce damage of tissue function. Before the operation of a surgical laparoscope or a retrolaparoscopic surgery, abdominal wall tissues are required to be separated bluntly, and a laparoscopic instrument operation space is created. The compression hemostasis is to press the bleeding part with force to achieve the purpose of hemostasis. Can be applied to a wide range of wound surfaces. Direct compression hemostasis is the most common method, and a certain pressure is directly applied to a wound to reduce or close a blood vessel laceration, slow blood flow, and quickly form thrombus such as platelets and fibrin so as to stop bleeding.
At present, no special abdominal cavity and posterior abdominal cavity tissue passive separation device exists in clinic, and the passive separation method used at present has a plurality of defects and shortcomings in practice.
In laparoscopic or retrolaparoscopic surgery, abdominal wall tissues are frequently required to be separated bluntly before surgery to create an abdominal operation space, and currently, a commonly used method is to perform incision on the abdominal wall, then fingers enter the abdominal wall to perform blunt separation, or surgical gloves and suture for ventilation tubes are used for bundling, so that a spherical sac is manufactured and is used in combination with a syringe. In the process of operation, the steps take special time to manufacture the balloon, certain experience is needed in the process of manufacturing the balloon, each step or each action is not in place, the result of manufacturing the balloon is possibly influenced, if the suture is tightly tied, the ventilated pipeline is tied, or the tying is too loose, so that the device is air-leaked, and the device needs to be manufactured again. In addition, another person is required to clamp the ventilation pipe with the vascular clamp in cooperation in the inflating process of the injector, so that a novice operator can obtain a satisfactory effect only by repeated tests, manpower and time are wasted, and the operation efficiency is greatly influenced.
Some cavity organs bleed in the operation, for example in gynaecology and obstetrics's operation, metrorrhagia, gastrointestinal bleeding, or for the unexpected injury internal organs hemorrhage in the outdoor emergency, sometimes need to use pressurization hemostasis method to stanch, need to flow out the blood that is abundant in the cavity, peritoneal effusion simultaneously, reduce the interference to the operation field of vision, at present there is not the device that pressurization hemostasis and drainage function combine yet clinically.
In addition, for some diseases in clinic, continuous drug infusion into a specific organ part is needed, for example, urinary bladder drug infusion in surgery, and a drug infusion device can be placed in the tissue of the diseased part to improve the absorption rate of the drug in the vascular system or other diseased tissues of body lumens. Currently, there are drug-coated balloon devices clinically applied to the fields of vascular surgery and interventional therapy, which enable almost all the drugs to be released to specific parts after expansion, but the device has disadvantages, for example, one balloon drug cannot be repeatedly used by the same patient after being released, and the type of drug loaded on the balloon is specific, and different drugs cannot be flexibly delivered according to different conditions.

The container 9 may be a vacuum bottle or a drug delivery bottle, depending on the clinical operating requirements. Of course, either the vacuum bottle or the administration bottle may be replaced with a syringe.
When the container 9 is a vacuum bottle, the vacuum bottle is communicated with the opened cavity organ sequentially through the drainage cavity 29, the exchange hole 28, the circulation cavity 804, the through hole 805 and the drainage hole 806 to form a drainage circuit. Due to the negative pressure inside the vacuum bottle, the accumulated liquid in the abdominal cavity or the posterior abdominal cavity is sucked into the vacuum bottle along the drainage route.
When the container 9 is a medicine feeding bottle, the medicine is filled in the medicine feeding bottle, and the medicine is conveyed to the specific wound part expanded by the balloon 8 along the drainage route so as to be used for cleaning or medicine feeding treatment.
In clinical application, the balloon 8 tube is placed on the corresponding part of the abdominal cavity or the posterior abdominal cavity, and the inner liner layer balloon 8 is inflated by using a manual air gun for blunt separation or is placed on the corresponding bleeding part for compression hemostasis. If only drainage is needed or the medicine is added directionally, the vacuum bottle or the medicine feeding bottle can be used independently. If only blunt separation is needed, the balloon 8 is inflated by the inflation tube 26 alone to be spread. For example, when it is necessary to perform drainage while applying pressure to stop bleeding, the inner container layer 801 may be spread apart and used in combination with a vacuum bottle.
Of course, in the above embodiment, the second control valve 22 may be replaced with a check valve.
