自吸式液体二氧化碳冷冻手术刀是利用液态二氧化碳作冷源的外科手术刀，通常由二氧化碳贮罐、截止阀、、电磁阀、联结管、毛细管、冷冻刀外筒、凹形刀面、控制器等部件组成。它利用抽气器形成负压把病患组织吸到内凹的冷冻手术刀上并使之逐步降温到－78度而使病患组织冻死。自吸式液体二氧化碳冷冻手术刀具有使用廉价、安全、方便、在负压吸引作用下切除肿瘤时癌细胞不易转移等优点。
Self-priming liquid carbon dioxide cryogenic scalpel is a surgical scalpel that uses liquid carbon dioxide as a cold source, usually consisting of a carbon dioxide storage tank, a stop valve, a solenoid valve, a connecting tube, a capillary tube, a frozen knife outer cylinder, a concave knife surface, and a controller. and other components. It uses an aspirator to form a negative pressure to suck the patient's tissue onto the concave cryosurgical knife and gradually cool it down to -78 degrees to freeze the patient's tissue to death. The self-priming liquid carbon dioxide cryosurgical knife has the advantages of low cost, safety and convenience, and the cancer cells are not easy to transfer when resecting tumors under the action of negative pressure suction.
Description
Technical field:
The title of patent of the present invention is a self-suction type liquid carbon freezing scalpel, belongs to medical instruments field.
Background technology:
Mostly present widely used its low-temperature receiver of medical cryoprobe is liquid nitrogen, liquid nitrogen temperature is subzero 196 degree, liquid nitrogen splashes on the skin will cold injury to cause and gives birth to security incident under such low temperature, and the gasification latent heat of liquid nitrogen is not high, and therefore in use also big, the cost of its consumption must increase.Also have the freezing cutter of a kind of immersion type it be will have the metal cutter of certain thermal capacitance insert to make it to drop in the liquid nitrogen again its to be taken out behind-196 degree and use, because cutter thermal capacity is limited, can only play the excision effect to shallow layer tissue and little pathological changes, and just powerless to big and dark position.The higher transportation of the cost of liquid nitrogen and store also inconvenient this situation that has just caused present medical refrigeration end generally to promote.
Summary of the invention:
For overcoming the deficiencies in the prior art, the present invention will adopt the latent heat of vaporization big (latent heat is about 3 times of liquid nitrogen) and evaporating temperature can reach the purpose that illing tissue is killed for-78.3 degree both safety.Utilize air ejector and bleeding point between spill knife face and pathological tissues, to make a negative-pressure vacuum environment, pathological tissues inhaled tightly be attached on the scalpel freezer surface, its temperature can remain unchanged for a long period of time, maintain about-78 degree, the working time of freezing cutter is set on controller computer by the doctor, can thoroughly freeze pathological tissues extremely.The present invention is with liquid CO particularly
2The working medium of storing in jar is guided on the joint on the self-suction type liquid carbon freezing scalpel handle of a knife by stop valve, electromagnetic valve and capillary tube, and a joint bottom and a tubule link, and the tubule other end directs at spill knife back face, allows liquid CO
2Spray makes it to keep about-78 degree thereon.Air ejector is a device with swabbing action, and it can be pump bowl, vacuum pump or other aspirators, but its interface is wanted and can be mated with bleeding point.Bleeding point is made up of gas passage, valve seat, mobile piston, and the piston upper end has a Shen to go out the valve rod of bleeding point in order to the vacuum between manual control spill knife face and the pathological tissues.Be wrapped in the heat-insulation layer that only exposes the cryoprobe of going to the bottom handle as self-priming liquid carbon dioxide cryoprobe in the urceolus outside.
Description of drawings:
Fig. 1 is self-priming liquid three carbonoxide cryoprobe structure charts, and Fig. 2 is the bleeding point structure chart, wherein: 1-spill knife face; 2-cross over pipe; 3-freezing cutter urceolus; 4-bleeding point; 5-bleeding point joint; 6-air ejector; 7-tubule; 8-joint; 9-capillary tube; 10-electromagnetic valve; 11-stop valve; 12-liquid CO 2 basin; 13-temperature sensor; 14-controller; 15-piston; 16-piston valve spindle; 17-valve seat.
The structure explanation:
Liquid carbon dioxide communicates with capillary tube 9 from 12 by 11,10, and 9 the other end and joint 8 link, and 8 lower end communicates with tubule 7.The middle part of spill knife face 1 has an aperture, and the bleeding point 4 that a cross over pipe 2 and freezing cutter urceolus 3 tops are housed on the hole joins, and 4 the other end is a bleeding point joint 5, connects with air ejector 6 herein.Be wrapped in the heat-insulation layer that only exposes the spill knife face of the going to the bottom handle as self-priming liquid carbon dioxide cryoprobe in the urceolus outside, the work of self-priming liquid carbon dioxide cryoprobe is regulated and control by controller 14.Temperature signal is taken from the temperature sensor 13 that places in the freezing cutter urceolus, and its signal is drawn from 3 top drillings.
The specific embodiment:
Fig. 1 also represents a cryoprobe schematic diagram that is used to excise cutaneous tumor.Its urceolus 3 diameters are 20mm, the cryosurgery knife face 1 that urceolus is gone to the bottom and made concave shaped, enter the capillary tube 9 of using the 3mm diameter from liquid CO 2 basin 12 effusive liquid CO 2s through stop valve 11, electromagnetic valve 10, spray to spill knife face inboard by joint 8 and tubule 7 then the knife face temperature is dropped to about-78 degree.Spill knife face middle part has an aperture, has connect a cross over pipe that joins with bleeding point 4 on the hole.The bleeding point other end is that bleeding point joint 5,5 is tied mutually with air ejector 6.Wrap as handle with the polyamine fat vacuole foam insulation material of thick 15mm in the outside at freezing cutter urceolus, and the work of electromagnetic valve is by controller 14 controls.After the spill knife face being covered on the pathological changes machine skin, can use aspirator that pathological tissues is inhaled tightly and be attached on the spill knife face, owing to suction function blood, tissue fluid etc. all concentrate this just can reduce cancerous cell diffusion probability to the spill knife face.When liquid CO 2 sprays from tubule, spill knife face temperature will be reduced to about-78 degree, and the pathological tissues of being close to it also can progressively be as cold as this temperature and freezed to death, thereby reach the purpose that tumor resection and non-proliferation shift.
