Description

Single use sterile hose cryoprobe

Technical field

This utility model relates to a kind of single use sterile hose cryoprobe, belongs to medical apparatus and instruments.

Background technology

Hose cryoprobe in use enters human body by scope, can treat the pathological changes in scope mouth front or pick foreign body.

The hose cryoprobe of current use comprises probe base assembly, air inlet pipe, polyfluortetraethylene pipe, the female sleeve pipe of band and with externally threaded cold head; Cold head is connected with polyfluortetraethylene pipe by joint sleeve, and concrete assembly relation is as follows;

First polyfluortetraethylene pipe is penetrated in described joint sleeve, alignd in the front end of the two, then the male thread portion of cold head be screwed into the front end of the joint sleeve being installed with polyfluortetraethylene pipe and be threaded with the female thread of joint sleeve, in fact, between cold head and the screw thread of joint sleeve, accompany the tube wall of polyfluortetraethylene pipe, such sealing effectiveness is best.

During use, gases at high pressure are released into atmosphere gas by air inlet pipe at cold head place, cause a large amount of heat absorption, make the temperature of cold head reach the treatment temperature of-40 DEG C--80 DEG C.

The material of above-mentioned cold head is silver-colored titanium alloy, the external diameter of cold head is 1.8-2.8mm, so thin cold head wants machining hole and external screw thread, also will on joint sleeve machining internal thread, percent defective is high, and assembling also very difficult, add silver-colored titanium alloy price higher, cause existing flexible pipe cryoprobe expensive, so above-mentioned hose cryoprobe is all repeatedly Reusability, there is the risk of cross infection between patient.

Utility model content

It is low that technical problem to be solved in the utility model is to provide a kind of cost, and processing and fabricating is easy to single use sterile hose cryoprobe.

This utility model solves the technical scheme that its technical problem adopts:

This utility model improves on the basis of existing hose cryoprobe, and its main improvement is the improvement to cold head part, and concrete technical scheme is as follows:

This utility model comprises probe base assembly, air inlet pipe and polyfluortetraethylene pipe; Also comprise cold head, throttle pipe and connection tube; The rearward end of described cold head is directly inserted in polyfluortetraethylene pipe, and be compact siro spinning technology, the rear end of described throttle pipe is inserted into tracheal strips, and be welded to connect with air inlet pipe, the rearward end sidewall of described connection tube is connected with the sidewall weld of throttle pipe, and the front end of described connection tube is sealed after welding with the front end of cold head.

The material of described cold head and connection tube is 316L medical stainless steel.

The material of described throttle pipe and air inlet pipe is rustless steel.

The beneficial effects of the utility model greatly reduce production cost, and processing and fabricating is simple, this probe can be made to become disposable sterile probe, avoid the cross infection between patient.

Accompanying drawing explanation

Fig. 1 is this utility model structural representation;

Fig. 2 is Fig. 1's place's partial enlarged drawing.

In Fig. 1-2: 1 probe base assembly, 2 cold heads, 3 connection tubes, 4 throttle pipes, 5 air inlet pipe, 6 polyfluortetraethylene pipes, 7 return gas channels, 8 steam vents.

Detailed description of the invention

From the embodiment described in Fig. 1-2, it comprises probe base assembly 1, air inlet pipe 5 and polyfluortetraethylene pipe 6; Also comprise cold head 2, throttle pipe 4 and connection tube 3; The rearward end of described cold head 2 is directly inserted in polyfluortetraethylene pipe 6, and be compact siro spinning technology, the rear end of described throttle pipe 4 is inserted in trachea 5, and be welded to connect with air inlet pipe 5, the rearward end sidewall of described connection tube 3 is connected with the sidewall weld of throttle pipe 4, the front end of described connection tube 3 is sealed after welding with the front end of cold head 2, adopts 316L medical stainless steel to weld etc. during the front end solder up of the front end of described connection tube 3 and cold head 2.

The material of described cold head 2 and connection tube 3 is 316L medical stainless steel.

The material of described throttle pipe 4 and air inlet pipe 5 is rustless steel.

By the cryoprobe that the present embodiment is produced, pack after sterilization, can as single use sterile hose cryoprobe.
